  • Prevalence of Nelson's syndrome after bilateral adrenalectomy in patients with cushing's disease: a systematic review and meta-analysis
  • 2021
  • Ingår i: Pituitary. - : Springer Science and Business Media LLC. - 1386-341X .- 1573-7403.
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose Bilateral adrenalectomy (BA) still plays an important role in the management of Cushing's disease (CD). Nelson's syndrome (NS) is a severe complication of BA, but conflicting data on its prevalence and predicting factors have been reported. The aim of this study was to determine the prevalence of NS, and identify factors associated with its development. Data sources Systematic literature search in four databases. Study Selection Observational studies reporting the prevalence of NS after BA in adult patients with CD. Data extraction Data extraction and risk of bias assessment were performed by three independent investigators. Data synthesis Thirty-six studies, with a total of 1316 CD patients treated with BA, were included for the primary outcome. Pooled prevalence of NS was 26% (95% CI 22-31%), with moderate to high heterogeneity (I-2 67%, P < 0.01). The time from BA to NS varied from 2 months to 39 years. The prevalence of NS in the most recently published studies, where magnet resonance imaging was used, was 38% (95% CI 27-50%). The prevalence of treatment for NS was 21% (95% CI 18-26%). Relative risk for NS was not significantly affected by prior pituitary radiotherapy [0.9 (95% CI 0.5-1.6)] or pituitary surgery [0.6 (95% CI 0.4-1.0)]. Conclusions Every fourth patient with CD treated with BA develops NS, and every fifth patient requires pituitary-specific treatment. The risk of NS may persist for up to four decades after BA. Life-long follow-up is essential for early detection and adequate treatment of NS.

  • Natural history and surgical outcome of Rathke's cleft cysts-A study from the Swedish Pituitary Registry
  • 2022
  • Ingår i: Clinical Endocrinology. - : Wiley. - 0300-0664 .- 1365-2265. ; 96:1, s. 54-61
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow-up of Rathke's cleft cysts vary since data on the natural history are sparse. Patients and Design Data at diagnosis and at 1, 5 and 10 years for patients with a Rathke's cleft cyst (434 at diagnosis, 317 females) were retrieved from the Swedish Pituitary Registry. Cysts <= 3 mm in diameter were excluded from the study. Measurements Data included demographics, cyst size, pituitary function, visual defects and surgery. Results The mean age at diagnosis was 45 years. In patients with cysts <10 mm in diameter (n = 204) 2.9% had pituitary hormone deficiencies and 2% had visual field impairments. Cyst size did not progress during the 5 years. Cysts with a diameter of >= 10 mm that were not operated (n = 174) decreased in size over the years (p < .01). Pituitary hormone deficiencies and visual impairments were more frequent (18% and 5.7%, respectively) but were stable over time. Transphenoidal surgery was performed in 56 patients of whom 51 underwent surgery before the 1-year follow-up. The mean cyst diameter at diagnosis was 18 mm (range: 930 mm), 36% had pituitary hormone deficiency, 45% had visual field defects and 20% had impaired visual acuity. One year after surgery 60% had no cyst remnants, 50% had a pituitary deficiency, 26% had visual field defects and 12% had impaired visual acuity. No major changes were observed after 5 years. Twelve of the operated patients had a follow-up at 10 years, in eight the cyst remnants or recurrences increased in size over time (p < .05). Conclusions Rathke's cleft cysts with a size less than 10 mm rarely grow and our results indicate that radiological follow-up can be restricted to 5 years. In contrast, progression of postoperative remnants or recurrent cysts is more likely and require long-term follow-up.

  • Pituitary function before and after surgery for nonfunctioning pituitary adenomas-data from the Swedish Pituitary Register.
  • 2023
  • Ingår i: European journal of endocrinology. - : Bioscientifica. - 1479-683X .- 0804-4643. ; 189:2, s. 217-224
  • Tidskriftsartikel (refereegranskat)abstract
    • Data on pre- and postoperative pituitary function in nonfunctioning pituitary adenomas (NFPA) are not consistent. We aimed to investigate pituitary function before and up to 5 years after transsphenoidal surgery with emphasis on the hypothalamic-pituitary-adrenal axis (HPA).Data from the Swedish Pituitary Register was used to analyze anterior pituitary function in 838 patients with NFPA diagnosed between 1991 and 2014. Patients who were reoperated or had received radiotherapy were excluded.Preoperative ACTH, TSH, LH/FSH, and GH deficiencies were reported in 31% (236/755), 39% (300/769), 51% (378/742), and 28% (170/604) of the patients, respectively. Preoperative median tumor volume was 5.0 (2.4-9.0) cm3. Among patients with preoperative, 1 year and 5 years postoperative data on the HPA axis (n = 428), 125 (29%) were ACTH-deficient preoperatively. One year postoperatively, 26% (32/125) of them had recovered ACTH function while 23% (70/303) patients had developed new ACTH deficiency. Thus, 1 year postoperatively, 163 (38%) patients were ACTH-deficient (P < .001 vs. preoperatively). No further increase was seen 5 years postoperatively (36%, P = .096). At 1 year postoperatively, recoveries in the TSH and LH/FSH axes were reported in 14% (33/241) and 15% (46/310), respectively, and new deficiencies in 22% (88/403) and 29% (83/288), respectively.Adrenocorticotrophic hormone deficiency increased significantly at 1 year postoperatively. Even though not significant, some patients recovered from or developed new deficiency between 1 and 5 years postoperatively. This pattern was seen in all axes. Our study emphasizes that continuous individual evaluations are needed during longer follow-up of patients operated for NFPA.

  • Achievements and experiences from science–policy interaction in the field of air pollution : Synthesising 20 years of research and outreach,thinking about future needs
  • 2021
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • For 20 years, the Swedish Environmental Protection Agency together with the MISTRA research foundation have funded five air pollution research programmes with focus on producing knowledge that supports policy and emission control in national and international arenas. The research has been multidisciplinary and has included research on emissions, atmospheric transport and transformation processes, human health effects, ecosystem effects, and emission control strategies. Research has also been conducted on the interaction between air pollution and climate change.Over these years, the link between the research programmes and the development of emission control strategies and policies in Sweden, the EU, and the UNECE Air Convention has been of high importance. This report presents how the research programmes have created societal benefits through support for the development of air pollution policies and emission control measures. The report also identifies future research needs to ensure continued progress towards even better air quality for future generations.

  • Acromegaly management in the Nordic countries: A Delphi consensus survey
  • 2024
  • Ingår i: Clinical Endocrinology. - : WILEY. - 0300-0664 .- 1365-2265.
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectiveAcromegaly is associated with increased morbidity and mortality if left untreated. The therapeutic options include surgery, medical treatment, and radiotherapy. Several guidelines and recommendations on treatment algorithms and follow-up exist. However, not all recommendations are strictly evidence-based. To evaluate consensus on the treatment and follow-up of patients with acromegaly in the Nordic countries.MethodsA Delphi process was used to map the landscape of acromegaly management in Denmark, Sweden, Norway, Finland, and Iceland. An expert panel developed 37 statements on the treatment and follow-up of patients with acromegaly. Dedicated endocrinologists (n = 47) from the Nordic countries were invited to rate their extent of agreement with the statements, using a Likert-type scale (1-7). Consensus was defined as >= 80% of panelists rating their agreement as >= 5 or <= 3 on the Likert-type scale.ResultsConsensus was reached in 41% (15/37) of the statements. Panelists agreed that pituitary surgery remains first line treatment. There was general agreement to recommend first-generation somatostatin analog (SSA) treatment after failed surgery and to consider repeat surgery. In addition, there was agreement to recommend combination therapy with first-generation SSA and pegvisomant as second- or third-line treatment. In more than 50% of the statements, consensus was not achieved. Considerable disagreement existed regarding pegvisomant monotherapy, and treatment with pasireotide and dopamine agonists.ConclusionThis consensus exploration study on the management of patients with acromegaly in the Nordic countries revealed a relatively large degree of disagreement among experts, which mirrors the complexity of the disease and the shortage of evidence-based data.

  • Long-term outcomes of patients with acromegaly: a report from the Swedish Pituitary Register
  • 2022
  • Ingår i: European Journal of Endocrinology. - : European Society of Endocrinology. - 1479-683X .- 0804-4643. ; 186:3, s. 329-339
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To describe the treatment and long-term outcomes of patients with acromegaly from all healthcare regions in Sweden. Design and methods: Analysis of prospectively reported data from the Swedish Pituitary Register of 698 patients (51% females) with acromegaly diagnosed from 1991 to 2011. The latest clinical follow-up date was December 2012, while mortality data were collected for 28.5 years until June 2019. Results: The annual incidence was 3.7/million; 71% of patients had a macroadenoma, 18% had visual field defects, and 25% had at least one pituitary hormone deficiency. Eighty-two percent had pituitary surgery, 10% radiotherapy, and 39% medical treatment. At the 5- and 10-year follow-ups, insulin-like growth factor 1 levels were within the reference range in 69 and 78% of patients, respectively. In linear regression, the proportion of patients with biochemical control including adjuvant therapy at 10 years follow-up increased over time by 1.23% per year. The standardized mortality ratio (SMR) (95% CI) for all patients was 1.29 (1.11-1.49). For patients with biochemical control at the latest follow-up, SMR was not increased, neither among patients diagnosed between 1991 and 2000, SMR: 1.06 (0.85-1.33) nor between 2001 and2011, SMR: 0.87 (0.61-1.24). In contrast, non-controlled patients at the latest follow-up from both decades had elevated SMR, 1.90 (1.33-2.72) and 1.98 (1.24-3.14), respectively. Conclusions: The proportion of patients with biochemical control increased over time. Patients with biochemically controlled acromegaly have normal life expectancy, while non-controlled patients still have increased mortality. The high rate of macroadenomas and unchanged age at diagnosis illustrates the need for improvements in the management of patients with acromegaly.

  • Understanding persons with psychological distress in primary health care
  • 2016
  • Ingår i: Scandinavian journal of caring sciences. - : Wiley. - 0283-9318 .- 1471-6712. ; 30:4, s. 687-694
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of this study was to gain more knowledge and a deeper understanding of experiences of persons living with psychological distress who seek help in primary care. Psychological distress is a state of emotional suffering associated with stressors and demands that are difficult to cope with in daily life. The lack of effective care for and difficulty in identifying psychological distress is frustrating for patients and health professionals alike. The aim was therefore to gain more knowledge about the experience of living with psychological distress. Twelve persons (nine women and three men) aged 23-51 years were interviewed. Analyses were based on a phenomenological hermeneutic method and indicated that psychological distress may be seen as an imbalance (incongruence) between the self and the ideal self, which slowly breaks down a person's self-esteem. This imbalance was described in three dimensions: Struggling to cope with everyday life, Feeling inferior to others and Losing one's grip on life. It seems to be associated with a gradual depletion of existential capacities and lead to dissatisfaction, suffering, poor self-esteem and lack of control. As psychological distress may be a forerunner to mental, physical and emotional exhaustion, there is a need to initiate preventive or early interventions to avoid mental, physical and emotional chaos in such patients. Patients' with psychological distress need to be involved in a person-centred salutogenic dialogue with health professionals to become aware of and strengthen their own capacities to regain health and well-being.

  • Increased Mortality Persists after Treatment of Cushing's Disease: A Matched Nationwide Cohort Study
  • 2022
  • Ingår i: Journal of the Endocrine Society. - : The Endocrine Society. - 2472-1972. ; 6:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Whether biochemical remission normalizes life expectancy in Cushing's disease (CD) patients remains unclear. Previous studies evaluating mortality in CD are limited by using the expected number of deaths in the background population instead of the actual number in matched controls. Objective and setting: To study mortality by time-to-event analysis in an unselected nationwide CD patient cohort. Design and participants: Longitudinal data from the Swedish Pituitary Register of 371 patients diagnosed with CD from 1991 to 2018 and information from the Swedish Cause of Death Register were evaluated. Four controls per patient (n = 1484) matched at the diagnosis date by age, sex, and residential area were included. Main outcome measures: Mortality and causes of death. Results: The median diagnosis age was 44 years (interquartile range 32-56), and the median follow-up was 10.6 years (5.7-18.0). At the 1-, 5-, 10-, 15-, and 20-year follow-ups, the remission rates were 80%, 92%, 96%, 91%, and 97%, respectively. Overall mortality was increased in CD patients compared with matched controls [hazard ratio (HR) 2.1 (95% CI 1.5-2.8)1. The HRs were 1.5 (1.02-2.2) for patients in remission at the last follow-up In = 303), 1.7 (1.03-2.8) for those in remission after a single pituitary surgery In = 177), and 5.6 (2.7-11.6) for those not in remission (n = 31). Cardiovascular diseases (32/66) and infections (12/66) were overrepresented causes of death. Conclusions: Mortality was increased in CD patients despite biochemical remission compared to matched controls. The study highlights the importance of careful comorbidity monitoring, regardless of remission status.

  • Psychotropic Drugs in Patients with Cushing's Disease Before Diagnosis and at Long-Term Follow-Up: A Nationwide Study
  • 2021
  • Ingår i: Journal of Clinical Endocrinology & Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 106:6, s. 1750-1760
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Psychiatric symptoms are common in Cushing's disease (CD) and seem only partly reversible following treatment. Objective: To investigate drug dispenses associated to psychiatric morbidity in CD patients before treatment and during long-term follow-up. Design: Nationwide longitudinal register-based study. Setting: University Hospitals in Sweden. Subjects: CD patients diagnosed between 1990 and 2018 (N = 372) were identified in the Swedish Pituitary Register. Longitudinal data was collected from 5 years before, at diagnosis, and during follow-up. Four matched controls per patient were included. Cross-sectional subgroup analysis of 76 patients in sustained remission was also performed. Main outcome measures: Data from the Swedish Prescribed Drug Register and the Patient Register. Results: In the 5-year period before and at diagnosis, use of antidepressants (odds ratio [OR] 2.2 [95% confidence interval (CI) 1.3-3.7]) and 2.3 [1.6-3.5]), anxiolytics [2.9 (1.6-5.3) and 3.9 (2.3-6.6)], and sleeping pills [2.1 (1.2-3.7) and 3.8 (2.4-5.9)] was more common in CD than controls. ORs remained elevated at 5-year follow-up for antidepressants [2.4 (1.53.9)] and sleeping pills [3.1 (1.9-5.3)]. Proportions of CD patients using antidepressants (26%) and sleeping pills (22%) were unchanged at diagnosis and 5-year follow-up, whereas drugs for hypertension and diabetes decreased. Patients in sustained remission for median 9.3 years (interquartile range 8.1-10.4) had higher use of antidepressants [OR 2.0 (1.1-3.8)] and sleeping pills [2.4 (1.3-4.7)], but not of drugs for hypertension. Conclusions: Increased use of psychotropic drugs in CD was observed before diagnosis and remained elevated regardless of remission status, suggesting persisting negative effects on mental health. The study highlights the importance of early diagnosis of CD, and the need for long-term monitoring of mental health.

  • Health-Related Quality of Life In Patients With Adrenal Insufficiency Receiving Plenadren Compared With Immediate-Release Hydrocortisone
  • 2015
  • Ingår i: Value in Health. - : Elsevier. - 1098-3015 .- 1524-4733. ; 18:7
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundPrevious studies in patients with primary adrenal insufficiency (PAI) on conventional replacement therapy suggest decreased health-related quality of life (HRQoL), and that patients report more frequently fatigue, increased anxiety and inability to work compared to background population.ObjectivesTo study self-reported health status with EQ-5D in patients with PAI. Patients treated with Plenadren (modified-release hydrocortisone) were compared with patients treated with immediate release hydrocortisone (IRHC) replacement therapy.MethodsThis was a cross-sectional, multi-centre, non-interventional survey of patients with PAI receiving Plenadren or immediate release hydrocortisone (IRHC) replacement.SubjectsOne hundred thirty-four adult patients with PAI of whom 36 (19 females [53%]) were treated with Plenadren and 98 (77 females [79%]) were treated with IRHC, were included.MAIN OUTCOME MEASUREHRQoL described by the EQ-5D, a generic preference-based measure of health.RESULTSPatients on Plenadren and on IRHC had a mean ± SD age of 53.1 ± 12.7 years and 48.0 ± 13.1 years, respectively (P=0.043). The majority of the patients were diagnosed more than 5 years ago (69%). The mean ± SD daily Plenadren and IRHC doses were 27.0 ± 6.8 mg and 26.6 ± 10.9 mg, respectively (P=0.807). 47% of the Plenadren patients had been receiving Plenadren and 82% of the IRHC patients had been receiving IRHC for more than 3 years. Patients receiving Plenadren had better HRQoL measured by the EQ-5D questionnaire compared to patients replaced with IRHC (0.76 ± 0.18 vs 0.68 ± 0.18, respectively [P=0.040]).CONCLUSIONSReplacement therapy with Plenadren in patients with PAI confers measurable benefit on HRQoL relative to IRHC as estimated by the EQ-5D questionnaire, and may therefore be advantageous when compared to IRHC substitution.

  • Non-physiological levels of circulating cortisol in growth hormone-treated hypopituitary adults after conventional cortisone substitution
  • 2004
  • Ingår i: Scandinavian Journal of Clinical and Laboratory Investigation. - : Informa UK Limited. - 0036-5513 .- 1502-7686. ; 64:2, s. 132-139
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To assess the usefulness of measuring plasma cortisol profiles in growth hormone-treated hypopituitary adults and to compare these with cortisol levels in healthy controls. Methods: Eleven ACTH-deficient adult patients received 12.5 mg cortisone-acetate orally at 16.00 h and 25 mg at 07.00 h. The patients arrived in the ward at 12.00 h. After tablet intake at 16.00 h, samples for serum cortisol were taken at hourly intervals for the next 24 h, except between 07.00 and 12.00 h when samples were drawn every half hour, 24-h urinary free cortisol (24-h-UFC) excretion was collected simultaneously. For comparison, 8 healthy controls were investigated. Results: The patients had circulating cortisol levels with very low plasma cortisol at 07.00 h before their morning dose of cortisone acetate. At the same time period, controls had their highest plasma cortisol levels. After tablet intake the patients had a rapid initial absorption of cortisol, but a marked variability in the morning peak levels (Cmax), and the Cmax was in general higher and occurred 90 min later than the Cmax in the controls. The 24-h-UFC excretion and 24-h area under the curve (24-h-AUC) did not differ between patients and controls. The female patients had higher 24-h-AUC for plasma cortisol (p=0.032) and tended to have higher plasma cortisol peaks in the morning, but had levels of 24-h-UFC similar to those of the male patients. Conclusions: Conventional cortisone substitution with a twice-daily replacement regimen in hypopituitary adults results in abnormal circulating cortisol profiles with low or non-measurable morning values and variable individual peaks. This suggests that the present dosing schemes have to be improved and that cortisone substitution should be individualized.

  • Limited value of cabergoline in Cushing's disease : a prospective study of a 6-week treatment in 20 patients
  • 2016
  • Ingår i: European Journal of Endocrinology. - : Bioscientifica. - 0804-4643 .- 1479-683X. ; 174:1, s. 17-24
  • Tidskriftsartikel (refereegranskat)abstract
    • CONTEXT AND OBJECTIVE: The role of cabergoline in Cushing's disease (CD) remains controversial. The experience is limited to case reports and few open studies that report the effects determined after ≥1 month of treatment. In prolactinomas and dopamine-responsive GH-secreting tumours, effects of cabergoline are seen within days or weeks. Here, we searched for short-term effects of cabergoline in CD.DESIGN: Twenty patients (19 naïve and one recurrent) were included in a prospective study. Cabergoline was administered in increasing doses of 0.5-5 mg/week over 6 weeks.METHODS: Urinary free cortisol (UFC) 24 h, morning cortisol and ACTH, and salivary cortisol at 0800, 1600 and 2300 h were determined once weekly throughout. Diurnal curves (six samples) of serum cortisol were measured at start and end.RESULTS: At study end, the median cabergoline dose was 5 mg, range 2.5-5 mg/week. The prolactin levels, markers of compliance, were suppressed in all patients. During the treatment, hypercortisolism varied, gradual and dose-dependent reductions were not seen. Five patients had a >50% decrease of UFC, three had a >50% rise of UFC. Salivary cortisol at 2300 h showed a congruent >50% change with UFC in two of the five cases with decreased UFC, and in one of the three cases with increased UFC. One patient with decreases in both UFC and 2300 h salivary cortisol also had a reduction in diurnal serum cortisol during the course of the study.CONCLUSIONS: Cabergoline seems to be of little value in the management of CD. Only one patient had a response-like pattern. Given the known variability of disease activity in CD, this might represent a chance finding.

  • Corticotroph Aggressive Pituitary Tumors and Carcinomas Frequently Harbor ATRX Mutations
  • 2021
  • Ingår i: Journal of Clinical Endocrinology & Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 106:4, s. 1183-1194
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Aggressive pituitary tumors (APTs) are characterized by unusually rapid growth and lack of response to standard treatment. About 1% to 2% develop metastases being classified as pituitary carcinomas (PCs). For unknown reasons, the corticotroph tumors are overrepresented among APTs and PCs. Mutations in the alpha thalassemia/mental retardation syndrome X-linked (ATRX) gene, regulating chromatin remodeling and telomere maintenance, have been implicated in the development of several cancer types, including neuroendocrine tumors. Objective: To study ATRX protein expression and mutational status of the ATRX gene in APTs and PCs. Design: We investigated ATRX protein expression by using immunohistochemistry in 30 APTs and 18 PCs, mostly of Pit-1 and T-Pit cell lineage. In tumors lacking ATRX immunolabeling, mutational status of the ATRX gene was explored. Results: Nine of the 48 tumors (19%) demonstrated lack of ATRX immunolabelling with a higher proportion in patients with PCs (5/18; 28%) than in those with APTs (4/30;13%). Lack of ATRX was most common in the corticotroph tumors, 7/22 (32%), versus tumors of the Pit-1 lineage, 2/24 (8%). Loss-of-function ATRX mutations were found in all 9 ATRX immunonegative cases: nonsense mutations (n = 4), frameshift deletions (n = 4), and large deletions affecting 22-28 of the 36 exons (n = 3). More than 1 ATRX gene defect was identified in 2 PCs. Conclusion: ATRX mutations occur in a subset of APTs and are more common in corticotroph tumors. The findings provide a rationale for performing ATRX immunohistochemistry to identify patients at risk of developing aggressive and potentially metastatic pituitary tumors.

    • Background: One of the most critical decisions that emergency department (ED) physicians make is the discharge versus admission of patients. We aimed to study the association of the decision in the ED to admit patients with chest pain and/or breathlessness to a ward with risk assessment using the Rapid Emergency Triage and Treatment System (RETTS), the National Early Warning Score (NEWS), and plasma levels of the biomarkers copeptin, midregional proadrenomedulin (MR-proADM), and midregional proatrial natriuretic peptide (MR-proANP). Methods: Patients presenting at the ED with chest pain and/or breathlessness with less than one week onset were enrolled. Patients were triaged according to RETTS. NEWS was calculated from the vital signs retrospectively. Results: Three hundred and thirty-four patients (167 males), mean age 63.8 +/- 16.8 years, were included. Of which, 210 (62.8%) patients complained of chest pain, 65 (19.5%) of breathlessness, and 59 (17.7%) of both. Of these, 176 (52.7%) patients were admitted to a ward, and 158 (47.3%) patients were discharged from the ED. In binary logistic models, age, gender, vital signs (O-2 saturation and heart rate), NEWS class, and copeptin were associated with admission to a ward from the ED. In receiver-operating-characteristics (ROC) analysis, copeptin had an incremental predictive value compared to NEWS alone (P = 0.002). Conclusions: Emergency physicians decisions to admit patients with chest pain and/or breathlessness from the ED to a ward are related to age, O-2 saturation, heart rate, NEWS category, and copeptin. As an independent predictive marker for admission, early analysis of copeptin might be beneficial when improving patient pathways at the ED.

  • A dose titration model for recombinant GH substitution aiming at normal plasma concentrations of IGF-I in hypopituitary adults
  • 2002
  • Ingår i: European Journal of Endocrinology. - : Oxford University Press (OUP). - 0804-4643 .- 1479-683X. ; 147:1, s. 49-57
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To evaluate a dose titration model for recombinant human GH substitution in adult patients with GH deficiency, aiming at normal plasma levels of IGF-I.DESIGN AND METHODS: Eighteen patients participated and a start dose of 0.17 mg GH/day was used except by two men who started with 0.33 mg/day. To demonstrate a clear GH effect the patients were first titrated, with steps of 0.17 mg GH/day every 6-8 weeks, to IGF-I levels in the upper range of age-adjusted reference values. The GH dose was then reduced 1 dose step and kept for a further 6 months. For comparison we investigated 17 healthy control subjects.RESULTS: Plasma IGF-I was increased after 2 weeks on the start dose and did not increase further for up to 8 weeks. Women had significantly lower GH sensitivity than men measured as net increment of IGF-I on the start dose of GH. GH sensitivity was not changed by age. The plasma IGF-I levels increased from 76.3+/-47.0 (s.d.) to 237+/-97 microg/l at the end of the study (P<0.001), and similar IGF-I levels were obtained in both sexes. The maintenance median GH dose was 0.33 mg/day in males and 0.83 mg/day in females (P=0.017). The GH dose correlated negatively with age in both sexes. Body weight, very low density triglycerides, lipoprotein(a) (Lp(a)), and fasting insulin increased, whereas insulin sensitivity index (QUICKI) decreased significantly. In comparison with the controls, the patients had lower fasting blood glucose, fasting insulin and Lp(a) levels at baseline, but these differences disappeared after GH substitution. The two groups had equal insulin sensitivity (QUICKI), but 2 h oral glucose tolerance test values of blood glucose and insulin were significantly higher in the patients at the end of the study.CONCLUSIONS: In conclusion our data suggest that the starting dose of GH substitution and the dose titration steps should be individualised according to GH sensitivity (gender) and the IGF-I level aimed for (age). The reduced insulin sensitivity induced by GH substitution could be viewed as a normalisation if compared with control subjects.

    • ContextCurrent guidelines on how to divide the daily cortisol substitution dose in patients with primary adrenal insufficiency (PAI) are controversial and mainly based on empirical data.ObjectiveTo assess how an equal dose of hydrocortisone given either four times daily or twice daily influence diurnal profiles of cortisol and ACTH, patient preferences and health related quality of life (HRQoL).DesignDouble blind, crossover.MethodsFifteen patients with PAI (6 women) were included. Capsules of hydrocortisone or placebo were given at 07:00, 12:00, 16:00 and 22:00 h in 4-week treatment periods: either one period with four doses (10+10+5+5 mg) or one period with two doses (20+0+10+0 mg). Diurnal profiles of cortisol and ACTH were collected and area under the curve (AUC) was calculated. Questionnaires were used to evaluate patient preferences and HRQoL.ResultsThe four-dose regimen gave a higher serum cortisol before tablet intake in the morning (P = 0.027) and a higher 24-h-cortisolAUC (P < 0.0001) compared with the two-dose period. In contrast a lower median plasma ACTH in the morning before tablet intake (P = 0.003) and a lower 24-h-ln(ACTHAUC) were found during the four-dose period. The patients preferred the four-dose regimen (P = 0.03), and the HRQoL scores tended to be higher (high score indicates better HRQoL) for the four-dose period.In summary a four-dose regimen gives increased availability of cortisol and an enhanced effect with a less elevated ACTH in the morning in comparison with a two-dose regimen but the effect on HRQoL remains inconclusive.

  • Circulating IGF-I concentrations are low and not correlated to glycaemic control in adults with type 1 diabetes
  • 2000
  • Ingår i: European Journal of Endocrinology. - : Oxford University Press (OUP). - 0804-4643 .- 1479-683X. ; 143:4, s. 505-510
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To study plasma concentrations of insulin-like growth factor-I (IGF-I) in adults with type 1 diabetes (IDDM) in comparison with a reference population, and the influence of glycaemic control, dose of insulin, and sex on the concentration of circulating IGF-I in IDDM.DESIGN AND METHODS: Patients with type 1 diabetes were recruited consecutively from our outpatient diabetes unit. In all, 79 men and 55 women aged 20-60 years with a disease duration >/=6 years (range 6-51 years) took part in the study. A reference population of 80 men and 83 women aged 20-60 years was randomly obtained from the population registry. IGF-I was measured with radioimmunoassay after acid-ethanol extraction.RESULTS: Mean +/- s. d. values of IGF-I were lower in patients with diabetes (146+/-66 microg/l) than in controls (238+/-83 microg/l, P<0.001). Those with diabetes had lower IGF-I concentrations in all age groups and the differences were highly significant in all decades except in women aged 50-59 years. IGF-I was negatively correlated with age in patients and controls. No correlation was found between IGF-I and glycaemic control measured as haemoglobin A(1c) (HbA(1c)) in the patients. IGF-I was positively associated with the dose of insulin/kg body weight in male patients independently of age, HbA(1c) and body mass index (P<0.03), but not in female patients (P=0.14).CONCLUSIONS: Our data show that IGF-I concentrations are low in adult patients with type 1 diabetes with a disease duration >/=6 years, independently of glycaemic control. This suggests that subcutaneous insulin substitution is inadequate to normalize circulating IGF-I concentrations in patients without endogenous insulin secretion.

  • European Adrenal Insufficiency Registry (EU-AIR): a comparative observational study of glucocorticoid replacement therapy
  • 2014
  • Ingår i: BMC Endocrine Disorders. - : BioMed Central (BMC). - 1472-6823. ; 14:40
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND:Increased morbidity and mortality associated with conventional glucocorticoid replacement therapy for primary adrenal insufficiency (primary AI; estimated prevalence 93-140/million), secondary AI (estimated prevalence, 150-280/million, respectively) or congenital adrenal hyperplasia (estimated prevalence, approximately 65/million) may be due to the inability of typical glucocorticoid treatment regimens to reproduce the normal circadian profile of plasma cortisol. A once-daily modified-release formulation of hydrocortisone has been developed to provide a plasma cortisol profile that better mimics the daytime endogenous profile of cortisol. Here, we describe the protocol for the European Adrenal Insufficiency Registry (EU-AIR), an observational study to assess the long-term safety of modified-release hydrocortisone compared with conventional glucocorticoid replacement therapies in routine clinical practice (ClinicalTrials.gov identifier: NCT01661387).METHODS:Patients enrolled in EU-AIR have primary or secondary AI and are receiving either modified-release or conventional glucocorticoid replacement therapy. The primary endpoints of EU-AIR are the incidence of intercurrent illness, adrenal crisis and serious adverse events (SAEs), as well as the duration of SAEs and dose changes related to SAEs. Data relating to morbidity, mortality, adverse drug reactions, dosing and concomitant therapies will be collected. Patient diaries will record illness-related dose changes between visits. All decisions concerning medical care are made by the registry physician and patient. Enrolment is targeted at achieving 3600 patient-years of treatment (1800 patient-years per group) for the primary analysis, which is focused on determining the non-inferiority of once-daily modified-release replacement therapy compared with conventional glucocorticoid therapy.RESULTS:Recruitment began in August 2012 and, as of March 2014, 801 patients have been enrolled. Fifteen centres are participating in Germany, the UK and Sweden, with recruitment soon to be initiated in the Netherlands.CONCLUSIONS:EU-AIR will provide a unique opportunity not only to collect long-term safety data on a modified-release preparation of glucocorticoid but also to evaluate baseline data on conventional glucocorticoid replacement. Such data should help to improve the treatment of AI.

  • Growth hormone substitution titrated to obtain IGF-I levels in the physiological range in hypopituitary adults : Effects upon dynamic strength, endurance and EMG
  • 2003
  • Ingår i: European Journal of Applied Physiology. - : Springer Science and Business Media LLC. - 1439-6319 .- 1439-6327. ; 90:5-6, s. 496-504
  • Tidskriftsartikel (refereegranskat)abstract
    • We studied the effects of individualised growth hormone (GH) substitution, aiming at normal insulin-like growth factor I (IGF-I) levels, on biomechanical output and surface electromyogram (EMG) of isokinetic muscle strength and endurance performance in 18 hypopituitary adults and compared with 17 matched healthy controls. The muscle function tests consisted of isokinetic contractions of the right knee extensors, from which torque and EMG were recorded. Three patients were excluded from the final analysis of the muscle function tests due to technical errors and one control subject moved from the area during the study. We found that GH-deficient adults without GH substitution were weaker and had less endurance than healthy control subjects. At the group level, plasma levels of IGF-I were normalised but generally no significant effects upon biomechanical output and EMG were found after dose titration and 6 months of a constant GH dose. However, subjects with the largest changes in IGF-I had significantly better biomechanical output and EMG compared to those with small changes in IGF-I. This finding may indicate that the net increase in IGF-I levels is critical for improvements in biomechanical output, EMG and perception of fatigue to occur.

  • IGF-I in growth hormone deficiency and in type 1 diabetes
  • 2002
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Both GH-deficiency and type 1 diabetes are associated with low IGF-I levels. The aim with our studies was to develop a dose titration model to obtain physiological IGF-I levels in growth hormone deficiency and to evaluate the relationship between glycaemic control and IGF-I in diabetes. First we established reference values for insulin like growth factor-I (IGF-I) and insulin like growth factor bindingprotein-1 (IGFBP-1) from 101 women and 101 men randomly selected from the population registry. No gender differences in IGF-I levels were fmmd. IGF-1 decreases with advancing age in both sexes, whereas IGFBP-1 increases with age.Titrating the GH dose according to population based reference values of IGF-I might be a way to obtain a fairly physiological substitution dose of GH. We hypothesised that a safe and probably effective maintenance dose of GH should increase IGF-I to the mean or slightly below the mean according to age adjusted reference levels. Eighteen adult hypopituitary patients with severe GH deficiency were titrated in steps, according to age adjusted IGF-I levels, to an individual dose of recombinant GH. For comparison 17 untreated healthy control subjects were evaluated. Similar IGF-1 levels armmd the mean for corresponding age were obtained in both sexes, but the maintenance median GH dose was more than twice in the women compared to men. The :individual dose differed markedly and elderly patients needed lower GH doses due to unchanged GH-sensitivity. Six months on the maintenance GH dose induced changes in blood-glucose, lipids, and insulin sensitivity index, indicating increased insulin resistance, which compared with the controls, were a normalisation. No major changes were seen in the variables of the renin-angiotensin-system. A significant increase in atrial natriuretic peptide seems also to be a normalisation if compared with the controls. The patients had less muscle strength and endmance at baseline compared with the controls and increased the muscle strength and endmance about 10 % after GH-substitution, an effect associated with the increase in IGF-I.Paradoxically circulating IGF-I is decreased in type 1 diabetes despite increased GH levels. We studied 134 adult patients with type I diabetes (aged 20-60 years), without endogenous insulin secretion, and found that circulating IGF-I were decreased to about 70 % of the values in the reference population. No con·elation between glycaemic control and IGF-I levels was found.To conclude the GH dose obtained when normalising circulating IGF-I according to population-based IGF-I levels, depends on GH-sensitivity (gender) and the IGF-1 level aimed for (age). In comparison with matched controls several OR-dependent variables are improved. In type 1 diabetes, our results suggests that the low IGF-I levels are independent of glycaemic control, and can not be corrected with subcutaneous insulin substitution.

  • Improved muscle function in GH substituted adults is related to increase in circulating IGF-I
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • We studied the effects of individualized growth hormone substitution, aiming at normal IGF-I levels, on biomechanical output and EMG of isokinetic muscle strength and endurance performance in 18 hypopituitary adults compared with matched controls. The muscle function tests consisted of isokinetic contractions of the dght knee extensors, and torque and EMG were recorded. Plasma levels of IGF-I were normalized, and peak torque at 90° s-1, and peak torque endurance level increased after dose titration and 6 months constant GH-dose. The change in IGF-I correlated positively with the changes in biomechanical output and EMG variables and a negative correlation existed with the perception of fatigue. Despite improvement during GH-substitution the patients still had about 10-20 % less muscle strength and endurance compared with the controls at the study end. In summary we found that individualized GH substitution improves muscle function and that the net increase in IGF-I levels indicates generally increases in biomechanical output and EMG variables and a lower perception of fatigue.

    • objective To study the effects of individualized recombinant GH substitution, aiming at normal circulating IGF-I levels, in GH-deficient adults on blood pressure, the renin–angiotensin–aldosterone system (RAAS), natriuretic peptides and urine free cortisol.study design Open study with control group. The patients were titrated in dose steps of 0·17 mg GH/day every 6–8 weeks until an IGF-I level around the mean + 1 SD was attained (Tmax). After another month the dose was reduced by 0·17 mg (minimum dose 0·17 mg/day) to produce IGF-I levels at or slightly below the age-related mean (Tend), and this maintenance dose was held constant for 6 months.subjects Eighteen patients (11 males and seven females) with GH deficiency participated. For comparison we also prospectively evaluated 17 matched control subjects.measurements Blood pressure and heart rate, circulating levels of IGF-I, plasma renin activity (PRA), immunoreactive active renin (IRR), angiotensin II, aldosterone, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and 24-h urine aldosterone and urine free cortisol levels.results Blood pressure was unchanged by GH substitution but heart rate increased significantly (P < 0·03). PRA was elevated on the highest GH dose (Tmax) compared to baseline (P < 0·01), but returned to baseline and levels of controls at Tend. Four patients developed transient oedema and tended to have higher PRA levels than the rest of the subjects (P = 0·09). The circulating levels of IRR, angiotensin II, aldosterone, BNP and 24-h urine aldosterone and urine free cortisol levels were unchanged by GH substitution, and did not differ from the levels in the control subjects. Baseline ANP levels in the patients were lower than in the controls (P < 0·01), but increased after GH substitution (P < 0·01) to levels found in with the controls.conclusions We found no major changes of the variables in the circulating renin–angiotensin–aldosterone system and a normalization of atrial natriuretic peptide when an individualized dose of GH was titrated to near-normal IGF-I levels.

    • Free milk-type oligosaccharides are produced during pregnancy and lactation and may have an impact on several cells in the immune system. Our aim was to investigate if patients with isolated hyperprolactinaemia, not related to pregnancy, also have increased synthesis and urinary excretion of milk-type oligosaccharides and to compare the excretion pattern with that found during pregnancy. Urine samples were collected as morning sample from 18 patients with hyperprolactinaemia, 13 healthy controls with normal prolactin levels and four pregnant women. After purification, lactose and free oligosaccharides were analysed and quantified by high-performance anion-exchange chromatography with pulsed amperometric detection. The identity of peaks was confirmed by exoglycosidase treatment and comparison with oligosaccharide standards. Prolactin was measured in serum collected between 09 and 11 a.m. by a standardized immunochemical method. Patients with hyperprolactinaemia had higher urinary excretion of lactose than normoprolactinemic controls and urinary lactose correlated positively to prolactin levels (r = 0.51, p < 0.05). Increased levels of the fucosylated oligosaccharides 2-fucosyl lactose and lacto-di-fucotetraose were found in urine from three and two patients, respectively. The acidic oligosaccharide 3-sialyl lactose was found in high amount in urine from two patients with prolactin of >10,000 mU/l. However, pregnant women in their third trimester had the highest concentration of all these oligosaccharides and excretion increased during pregnancy. This study is first to show that both lactose and certain fucosylated and sialylated milk-type oligosaccharides are increased in some patients with hyperprolactinaemia. It remains to elucidate the functional importance of these findings.

    • Our aim was to investigate the usefulness of circulating levels of adrenocorticotropic hormone (ACTH) and also salivary cortisol to monitor cortisone substitution in patients with Addisons disease. 13 patients with primary adrenal insufficiency (8 women and 5 men, age 44 +/- 11 years) received 12.5 mg cortisone acetate orally at 16:00 h and 25 mg at 07:00 h. Blood samples for cortisol and ACTH analysis were drawn every hour for 24 h, and also every half hour between 07:00 and 12:00 h. Samples for salivary cortisol were collected in parallel. Total ACTH levels showed large inter-individual variations and a diurnal rhythm with a nadir in the early evening at 19:00 (median 19 ng/l, range 2-434 ng/l) and high levels in the early morning, with a peak around 07:30 (median 844 ng/l, range 45-2 249 ng/l). Plasma cortisol concentrations showed 2 peaks distinct in time, but variable in height, 1-2 h after intake of cortisone. Plasma cortisol correlated significantly with ln(ACTH) at 17:00 h (r = -0.56), at 10:00 h (r = -0.51), and at 10.30 h (r = -0.57). When tested at different time points, ln(ACTH) at 10:00 to 12:00 h was negatively correlated with plasma cortisol between 08:30 and 12:00 h. Plasma cortisol was highly correlated to ln(salivary cortisol) most of the time points measured, but 30-60 min after intake of cortisone acetate the correlation disappeared. In conclusion, the large interindividual variation in ACTH levels most likely indicates varying sensitivity to cortisol with a need for individualized dosing schemes. Furthermore ACTH-determinations may be useful for dose titration of cortisol.

    • Emerging scientific knowledge such as the role of epigenetics and neuroplasticity—the brain’s capability to constantly rewire with every action, experience, and thought—is fundamentally changing our understanding of the potential impact we can have on our brain. Our brain is formed by our habits in interaction with our body, the environment, influenced by our lifestyle, successes, failures, and traumas. Neuroplasticity proves that every student’s brain is a work in progress, and it is never too late to take better care of one’s cognitive fitness. This review presents a repertoire of good habits (GHs). Combined, we suggest that these GHs provide conditions for optimal brain health, by acting as a “Mental Vaccine” which enhances the brain’s resilience to brain health-degrading challenges. We argue hat schools have a crucial role to play in empowering students to increase their own stress resilience, well-being, and learning by developing their own GHs profile.

    • Prolactin has many physiological effects and seems to be involved in the human quality of life and well-being. The aim of this study was to describe health related quality of life, fatigue and daytime sleepiness in women with untreated hyperprolactinemia. In total 32 women (mean age 37.0 ± 10.9) with verified hyperprolactinemia completed a questionnaire including questions on fatigue, measured with the Swedish version of the Fatigue Impact Scale (FIS), propensity to fall in sleep, measured with the Swedish version of the Epworth Sleepiness Scale (ESS), and Health related quality of life (HRQoL), measured by the Short-Form-36 scale (SF-36). For comparison Swedish normative data were used. The women were also interviewed regarding different symptoms related to hyperprolactinemia and the answers were analyzed using qualitative content analysis. HRQoL, as measured with SF-36, was significantly lower in all dimensions, except in physical function, compared to the Swedish reference population. Total FIS was 54.3 (41.1) and mean score on the ESS was 8.7 (4.2) indicating increased fatigue and deterioration in night sleep. The women felt very tired, and several of them rarely felt rested in the morning. The restless night sleep and the fatigue during the daytime got them to feel feeble and sometimes to find it difficult to concentrate, which affected both their mood and life in general. Women diagnosed with hyperprolactinemia reported deterioration in night sleep, increased rate of fatigue, and a reduced health related quality of life in comparison with the reference population.

    • Oral once-daily dual-release hydrocortisone (DR-HC) replacement therapy has demonstrated an improved metabolic profile compared to conventional 3-times-daily (TID-HC) therapy among patients with primary adrenal insufficiency. This effect might be related to a more physiological cortisol profile, but also to a modified pattern of cortisol metabolism.To study cortisol metabolism during DR-HC and TID-HC.Randomized, 12-week, crossover study.DC-HC and same daily dose of TID-HC in patients with primary adrenal insufficiency (n=50) versus healthy subjects (n=124) as control.Urinary corticosteroid metabolites measured by gas chromatography/mass spectrometry on 24-hour urinary collections.Total cortisol metabolites decreased during DR-HC compared to TID-HC (P < 0.001) and reached control values (P = 0.089). During DR-HC, 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activity measured by tetrahydrocortisol+5α-tetrahydrocortisol/tetrahydrocortisone ratio was reduced compared to TID-HC (P < 0.05), but remained increased versus controls (P < 0.001). 11β-HSD2 activity measured by urinary free cortisone/free cortisol ratio was decreased with TID-HC versus controls (P < 0.01) but normalized with DR-HC (P = 0.358). 5α- and 5β-reduced metabolites were decreased with DR-HC compared to TID-HC. Tetrahydrocortisol/5α-tetrahydrocortisol ratio was increased during both treatments, suggesting increased 5β-reductase activity.The urinary cortisol metabolome shows striking abnormalities in patients receiving conventional TID-HC replacement therapy with increased 11β-HSD1 activity that may account for the unfavorable metabolic phenotype in primary adrenal insufficiency. Its change towards normalization with DR-HC may mediate beneficial metabolic effects. The urinary cortisol metabolome may serve as a tool to assess optimal cortisol replacement therapy.

    • Prolactin is known to have immune modulatory effects acting through the prolactin receptor, which is present on a variety of immune cells. Certain chemokines contribute to form the type of T helper (Th) preponderance in the immune response. The objective of this work was to assess if hyperprolactinemia not related to pregnancy is associated with changes in circulating levels of chemokines and other immunological markers. In this cross sectional study, 35 patients with hyperprolactinemia (5 men), and 102 healthy blood donors (19 men) were included. Serum levels of Th1- Th2- and Th17-associated chemokines, C-reactive protein, immunoglobulins, and the B cell attracting chemokine CXCL13 were assessed. The hyperprolactinemic group had significantly higher levels of Th2 associated CCL22 (p=0.022), Th17 associated CXCL1 (p=0.001), B cell attracting CXCL13 (p=0.003), and C-reactive protein (p<0.001) compared to controls, and these proteins were also positively correlated with prolactin levels. While differences in CCL22, CXCL1, CXCL13, and C-reactive protein were present in patients with low or moderate hyperprolactinemia, no differences were observed at high (>3600 mU/l) prolactin levels. To evaluate a possible dose-associated response to prolactin, an in vitro model was used, showing prolactin-induced increase in T-helper cell activation at moderate levels, while activation decreased at higher levels. Hyperprolactinemia seems to have several immunomodulatory effects and was associated with increased levels of chemokines associated with Th2 and Th17 responses and B cell attraction. However, patients with greatly increased prolactin had normal levels of chemokines, and in vitro, high levels of prolactin decreased T-helper cell activation.

  • Detailed assessment of hypothalamic damage in craniopharyngioma patients with obesity
  • 2019
  • Ingår i: International Journal of Obesity. - : Springer Science and Business Media LLC. - 0307-0565 .- 1476-5497. ; 43:3, s. 533-544

    • Background/objectives: Hypothalamic obesity (HO) occurs in 50% of patients with the pituitary tumor craniopharyngioma (CP). Attempts have been made to predict the risk of HO based on hypothalamic (HT) damage on magnetic resonance imaging (MRI), but none have included volumetry. We performed qualitative and quantitative volumetric analyses of HT damage. The results were explored in relation to feeding related peptides and body fat. Subjects/methods: A cross-sectional study of childhood onset CPs involving 3 Tesla MRI, was performed at median 22 years after first operation; 41 CPs, median age 35 (range: 17–56), of whom 23 had HT damage, were compared to 32 controls. After exclusions, 35 patients and 31 controls remained in the MRI study. Main outcome measures were the relation of metabolic parameters to HT volume and qualitative analyses of HT damage. Results: Metabolic parameters scored persistently very high in vascular risk particularly among HT damaged patients. Patients had smaller HT volumes compared to controls 769 (35–1168) mm3 vs. 879 (775–1086) mm3; P < 0.001. HT volume correlated negatively with fat mass and leptin among CP patients (rs = −0.67; P <.001; rs = −0.53; P = 0.001), and explained 39% of the variation in fat mass. For every 100 mm3 increase in HT volume fat mass decreased by 2.7 kg (95% CI: 1.5–3.9; P < 0.001). Qualitative assessments revealed HT damage in three out of six patients with normal volumetry, but HT damage according to operation records. Conclusions: A decrease in HT volume was associated with an increase in fat mass and leptin. We present a method with a high inter-rater reliability (0.94) that can be applied by nonradiologists for the assessment of HT damage. The method may be valuable in the risk assessment of diseases involving the HT.

    • Context: Patients with craniopharyngioma (CP) and hypothalamic lesions (HL) have cognitive deficits. Which neural pathways are affected is unknown. Objective: To determine whether there is a relationship between microstructural white matter (WM) alterations detected with diffusion tensor imaging (DTI) and cognition in adults with childhood-onset CP. Design: A cross-sectional study with a median follow-up time of 22 (6-49) years after operation. Setting: The South Medical Region of Sweden (2.5 million inhabitants). Participants: Included were 41 patients (24 women, amp;gt;= 17 years) surgically treated for childhood-onset CP between 1958-2010 and 32 controls with similar age and gender distributions. HI was found in 23 patients. Main outcome measures: Subjects performed cognitive tests and magnetic resonance imaging, and images were analyzed using DTI of uncinate fasciculus, fornix, cingulum, hippocampus and hypothalamus as well as hippocampal volumetry. Results: Right uncinate fasciculus was significantly altered (P amp;lt;= 0.01) Microstructural WM alterations in left ventral cingulum were significantly associated with worse performance in visual episodic memory, explaining approximately 50% of the variation. Alterations in dorsal cingulum were associated with worse performance in immediate, delayed recall and recognition, explaining 26-38% of the variation, and with visuospatial ability and executive function, explaining 19-29%. Patients who had smaller hippocampal volume had worse general knowledge (P = 0.028), and microstructural WM alterations in hippocampus were associated with a decline in general knowledge and episodic visual memory. Conclusions: A structure to function relationship is suggested between microstructural WM alterations in cingulum and in hippocampus with cognitive deficits in CP.

    • To describe the clinical presentation and treatment outcomes in a nationwide cohort of patients with giant prolactinomas.Register-based study of patients with giant prolactinomas [serum prolactin (PRL) > 1000 µg/L, tumor diameter ≥40 mm] identified in the Swedish Pituitary Register 1991-2018.Eighty-four patients [mean age 47 (SD ±16) years, 89% men] were included in the study. At diagnosis, the median PRL was 6305 µg/L (range 1450-253 000), the median tumor diameter was 47 mm (range 40-85), 84% of the patients had hypogonadotropic hypogonadism, and 71% visual field defects. All patients were treated with a dopamine agonist (DA) at some point. Twenty-three (27%) received 1 or more additional therapies, including surgery (n = 19), radiotherapy (n = 6), other medical treatments (n = 4), and chemotherapy (n = 2). Ki-67 was ≥10% in 4/14 tumors. At the last follow-up [median 9 years (interquartile range (IQR) 4-15)], the median PRL was 12 µg/L (IQR 4-126), and the median tumor diameter was 22 mm (IQR 3-40). Normalized PRL was achieved in 55%, significant tumor reduction in 69%, and combined response (normalized PRL and significant tumor reduction) in 43%. In the primary DA-treated patients (n = 79), the reduction in PRL or tumor size after the first year predicted the combined response at the last follow-up (P < .001 and P = .012, respectively).DAs effectively reduced PRL and tumor size, but approximately 1 patient out of 4 needed multimodal treatment. Our results suggest that the response to DA after 1 year is useful for identifying patients who need more careful monitoring and, in some cases, additional treatment.

  • Altered immunoglobulin G glycosylation in patients with isolated hyperprolactinaemia
  • 2021

  • Tidskriftsartikel (refereegranskat)abstract
    • Prolactin is a peptide hormone produced in the anterior pituitary, which increase in several physiological and pathological situations. It is unclear if hyperprolactinaemia may affect glycosylation of immunoglobulin G (IgG). Twenty-five patients with hyperprolactinemia and 22 healthy control subjects were included in the study. The groups had similar age and gender distribution. A panel of hormonal and haematological analyses, creatinine, glucose, liver enzymes and immunoglobulins were measured by routine clinical methods. IgG was purified from serum by Protein G Sepharose. Sialic acid was released from IgG by use of neuraminidase followed by quantification on high performance anion-exchange chromatography with pulsed amperometric detection. Tryptic glycopeptides of IgG was analysed by matrix-assisted laser desorption/ionization-time of flight mass spectrometry. Hormone and immunoglobulin levels were similar in the two groups, except for IgA and prolactin. Significantly higher IgG1 and IgG2/3 galactosylation was found in the patient group with hyperprolactinaemia compared to controls. (A significant correlation between prolactin and IgG2/3 galactosylation (Rs 0.61, p<0.001) was found for samples with prolactin values below 2000 mIU/L. The relative amount of sialylated and bisecting glycans on IgG did not differ between patients and controls. The four macroprolactinaemic patients showed decreased relative amount of bisecting IgG2/3 glycans. Hyperprolactinaemia was found to be associated with increased galactosylation of IgG1 and IgG2/3. This may have impact on IgG interactions with Fc-receptors, complement and lectins, and consequently lead to an altered immune response.

    • Fracture risk in GHD patients is not definitely established. Studying fracture incidence in 832 patients on GH therapy and 2581 matched population controls, we recorded a doubled fracture risk in CO GHD women, but a significantly lower fracture risk in AO GHD men. Introduction: The objective of this study was to evaluate fracture incidence in patients wilh confirmed growth hormone deficiency (GHD) on replacement therapy (including growth hormone [GH]) compared with population controls, while also taking potential confounders and effect modifiers into account. Materials and Methods: Eight hundred thirty-two patients with GHD and 2581 matched population controls answered a questionnaire about fractures and other background information. Incidence rate ratio (IRR) and 95% CI for first fracture were estimated. The median time on GH therapy for childhood onset (CO) GHD men and women was 15 and 12 yr, respectively, and 6 and 5 yr for adult onset (AO) GHD men and women, respectively. Results: A more than doubled risk (IRR, 2.29; 95% CI, 1.23-4.28) for nonosteoporotic fractures was recorded in women with CO GHD, whereas no risk increase was observed among CO GHD men (IRR. 0.61) and AO GHD women (IRR, 1.08). A significantly decreased incidence of fractures (IRR, 0.54; 95% CI 0.34-0.86) was recorded in AO GHD men. Conclusions: Increased fracture risk in CO GHD women can most likely be explained by interaction between oral estrogen and the GH-IGF-I axis. The adequate substitution rate of testosterone (90%) and GH (94%) may have resulted in significantly lower fracture risk in AO GHD men.

    • Context: Data on bone mineral density (BMD) are lacking in adults with childhood onset (CO)-craniopharyngioma (CP) with hypothalamic damage from the tumor. In patients with CO GH deficiency, BMD increases during GH treatment. Objective: The aims were to evaluate BMD in adults with CO-CPs on complete hormone replacement, including long-term GH and to evaluate the impact of hypothalamic damage on these measures. Design and participants: BMD (dual-energy X-ray absorptiometry), markers of bone turn over, physical activity and calcium intake were assessed in 39 CO-CP adults (20 women), with a median age of 28 (17-57) years, in comparison with matched population controls. Results: Late puberty induction was recorded in both genders, but reduced androgen levels in females only. Only CP women had lower BMD (PZ0.03) at L2-L4, and reduced Z-scores at femoral neck (P=0.004) and L2-L4 (P=0.004). Both genders had increased serum leptin levels (P=0.001), which significantly correlated negatively with BMD at L2-L4 (P=0.003; r=-0.5) and 45% of CP women had Z-score levels less than= -2.0 S.D. Furthermore, 75% of those with a Z-score less than= -2.0 S.D. had hypothalamic involvement by the tumor. Calcium intake (P=0.008) and physical activity (P=0.007) levels were reduced in CP men only. Levels of ostecalcin and crossLaps were increased in CP men only. Conclusions: Despite continuous GH therapy, low BMD was recorded in CO-CP females. Insufficient estrogen and androgen supplementation during adolescence was the main cause, but hypothalamic involvement with consequent leptin resistance was also strongly associated with low BMD in both genders.

    • Context: Craniopharyngioma patients without GH therapy are at an increased cardiovascular disease (CVD) risk and particularly concerning women. No previous study on long-term GH therapy in adults with childhood onset (CO) craniopharyngioma was identified. Objective: To investigate CVD risk in adults with CO craniopharyngioma on complete hormone replacement, including long-term GH therapy, and to investigate the impact of disease-related factors on CVD risk. Design and participants: In a cross-sectional study of operated CO craniopharyngiomas (1958–2000) from a defined area of Sweden (2.5 million), we enrolled 42 patients (20 women) with a median age of 28 years (range 17–57) and assessed CVD risk of 20 (4–40) years after first operation. Comparisons were made with matched controls and between patients with tumor growth into the third ventricle (TGTV) versus non-TGTV. GH therapy was 10–12 years in women and men. Results: In comparison with controls, both male and female patients had increased body mass index, fat mass, insulin, and leptin levels. Overall, while not significantly increased in male patients, 55–60% of female patients had a medium–high CVD risk, compared with 10–20% in controls. An increased CVD risk (all P<0.05) and higher levels of fat mass and insulin were recorded in the TGTV group versus the non-TGTV group. Late puberty induction and lack of androgens were shown in female patients. Conclusions: Adult patients with CO craniopharyngioma, especially those with TGTV, have persistently increased CVD risk. Conventional hormone substitution, including GH, is insufficient to normalize CVD risk, suggesting an important role for irreversible hypothalamic dysfunction.

    • Context: The impact of long-term GH replacement on cerebrovascular and cardiovascular diseases and diabetes mellitus in hypopituitary patients is unknown. Objective: The incidence of nonfatal stroke and cardiac events, and prevalence of type 2 diabetes mellitus ( T2D) and cardioprotective medication were compared between cohorts of GH-deficient (GHD) patients and population controls. Design and Participants: The incidence of nonfatal stroke and cardiac events was estimated retrospectively from questionnaires in 750 GHD patients and 2314 matched population controls. A prevalence of T2D and cardioprotective medication was recorded at the distribution of questionnaires. Time since first pituitary deficiency to start of GH therapy was 4 and 2 yr, and time on GH therapy was 6 yr for GHD women and men, respectively. Results: Lifelong incidence of nonfatal stroke was tripled in GHD women and doubled in GHD men, but a decline was seen in both genders during periods after first pituitary hormone deficiency and GHD, during which most patients had GH therapy. The lifelong incidence of nonfatal cardiac events declined in GHD men during first pituitary hormone deficiency and GHD periods. GHD women had a higher prevalence of T2D and lipid-lowering medication, whereas GHD men had a higher prevalence of antihypertensive medication. Conclusions: The declined risks of nonfatal stroke in both genders and of nonfatal cardiac events in GHD men during periods on GH replacement may be caused by prescription of cardioprotective drugs and 6-yr GH replacement. GHD women had an increased prevalence of T2D, partly attributed to higher body mass index and lower physical activity.

  • Reduced Energy Expenditure and Impaired Feeding-Related Signals But Not High Energy Intake Reinforces Hypothalamic Obesity in Adults with Childhood Onset Craniopharyngioma
  • 2010
  • Ingår i: Journal of Clinical Endocrinology and Metabolism. - : Endocrine Society. - 0021-972X .- 1945-7197. ; 95:12, s. 5395-5402
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Obesity is a frequent manifestation of hypothalamic damage from a craniopharyngioma (CP). It is not yet clarified whether the obesity is due to alterations in energy expenditure, i.e. basal metabolic rate (BMR) and physical activity, or to increased energy intake (EI). Objective: The aim was to investigate whether energy expenditure and EI differed between childhood onset CP patients and matched population controls and whether these measures were related to hypothalamic damage, as tumor growth into the third ventricle (TGTV). Design and Methods: Forty-two CP patients (20 women) aged 28 yr (range, 17-57 yr) operated between 1958 and 2000 in the South Medical Region of Sweden (population, 2.5 million) were studied. Body composition, satiety hormones, BMR (indirect calorimetry), physical activity, EI, and attitudes toward eating were assessed. Comparisons were made with matched controls and between patients with (n = 25) and without (n = 17) TGTV. Results: After adjustment, patients had lower BMR compared to controls (-90 kcal/24 h; P = 0.02) and also had lower EI (1778 vs. 2094 kcal/24h; P = 0.008), and the EI/BMR ratio was significantly lower in TGTV patients. Similar dietary macronutrient composition was found, and only significantly higher scales in restricting food intake were recorded in patients. Ghrelin levels were significantly lower in patients, whereas serum insulin and leptin levels were higher (P less than 0.001), and both ghrelin and insulin correlated significantly to tumor growth. Lower levels of physical activity (P less than 0.01) were recorded in patients. Conclusions: The major mechanisms that reinforced obesity were hypothalamic damage causing disrupted or impaired sensitivity to feeding-related signals for leptin, insulin, and ghrelin, and reductions in both BMR and physical activity.

  • Ingår i: Journal of Medical Economics. - : Informa Healthcare. - 1369-6998 .- 1941-837X. ; 23:11, s. 1311-1320
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Aims: The ReFLeCT study demonstrated that switching to insulin degludec from other basal insulins was associated with reductions in glycated hemoglobin and hypoglycemic events in type 1 (T1D) and type 2 diabetes (T2D), and reductions in insulin doses in T1D. The aim of the present analysis was to assess the short- and long-term cost-effectiveness of switching to insulin degludec in Sweden.Methods: Short-term outcomes were evaluated over 1 year in a Microsoft Excel model, while long-term outcomes were projected over patient lifetimes using the IQVIA CORE Diabetes Model. Cohort characteristics and treatment effects were sourced from the ReFLeCT study. Costs (in 2018 Swedish krona [SEK]) encompassed direct medical expenditure and indirect costs from loss of workplace productivity. In the long-term analyses, patients were assumed to receive insulin degludec or continue prior insulin therapy (primarily insulin glargine U100) for 5 years, before all patients intensified to once-daily degludec and mealtime aspart.Results: Switching to insulin degludec was associated with improved quality-adjusted life expectancy of 0.04 and 0.02 quality-adjusted life years (QALYs) over 1 year, and 0.16 and 0.08 QALYs over patient lifetimes, in T1D and T2D. Combined costs in T1D and T2D were estimated to be SEK 1 249 lower and SEK 1 181 higher over the short term, and SEK 157 258 and SEK 2 114 lower over the long term. Benefits were due to lower insulin doses in T1D, reduced rates of hypoglycemia and lower incidences of diabetes-related complications. Insulin degludec was associated with an incremental cost-effectiveness ratio of SEK 64 298 per QALY gained for T2D over 1 year and considered dominant for T1D and T2D in all other comparisons.Conclusions: Insulin degludec was projected to be cost-effective or dominant versus other basal insulins for the treatment of T1D and T2D in Sweden.

    • Context: Patients with treated adrenal insufficiency (AI) have increased morbidity and mortality rate. Our goal was to improve outcome by developing a once-daily (OD) oral hydrocortisone dual-release tablet with a more physiological exposure-time cortisol profile.Objective: The aim was to compare pharmacokinetics and metabolic outcome between OD and the same daily dose of thrice-daily (TID) dose of conventional hydrocortisone tablets.Design and Setting: We conducted an open, randomized, two-period, 12-wk crossover multicenter trial with a 24-wk extension at five university hospital centers.Patients: The trial enrolled 64 adults with primary AI; 11 had concomitant diabetes mellitus (DM).Intervention: The same daily dose of hydrocortisone was administered as OD dual-release or TID.Main Outcome Measure: We evaluated cortisol pharmacokinetics.Results: Compared with conventional TID, OD provided a sustained serum cortisol profile 0-4 h after the morning intake and reduced the late afternoon and the 24-h cortisol exposure. The mean weight (difference = -0.7 kg, P = 0.005), systolic blood pressure (difference = -5.5 mm Hg, P = 0.0001) and diastolic blood pressure (difference: -2.3 mm Hg; P = 0.03), and glycated hemoglobin (absolute difference = -0.1%, P = 0.0006) were all reduced after OD compared with TID at 12 wk. Compared with TID, a reduction in glycated hemoglobin by 0.6% was observed in patients with concomitant DM during OD (P = 0.004).Conclusion: The OD dual-release tablet provided a more circadian-based serum cortisol profile. Reduced body weight, reduced blood pressure, and improved glucose metabolism were observed during OD treatment. In particular, glucose metabolism improved in patients with concomitant DM.

  • Increased Risk of Drug-Induced Hyponatremia during High Temperatures
  • 2017
  • Ingår i: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 14:7
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To investigate the relationship between outdoor temperature in Sweden and the reporting of drug-induced hyponatremia to the Medical Products Agency (MPA). Methods: All individual adverse drug reactions (ADR) reported to MPA from 1 January 2010 to 31 October 2013 of suspected drug-induced hyponatremia and random controls were identified. Reports where the ADR had been assessed as having at least a possible relation to the suspected drug were included. Information on administered drugs, onset date, causality assessment, sodium levels, and the geographical origin of the reports was extracted. A case-crossover design was used to ascertain the association between heat exposure and drug-induced hyponatremia at the individual level, while linear regression was used to study its relationship to sodium concentration in blood. Temperature exposure data were obtained from the nearest observation station to the reported cases. Results: During the study period, 280 reports of hyponatremia were identified. More cases of drug-induced hyponatremia were reported in the warmer season, with a peak in June, while other ADRs showed an opposite annual pattern. The distributed lag non-linear model indicated an increasing odds ratio (OR) with increasing temperature in the warm season with a highest odds ratio, with delays of 1-5 days after heat exposure. A cumulative OR for a lag time of 1 to 3 days was estimated at 2.21 at an average daily temperature of 20 degrees C. The change in sodium per 1 degrees C increase in temperature was estimated to be -0.37 mmol/L (95% CI: -0.02, -0.72). Conclusions: Warm weather appears to increase the risk of drug-induced hyponatremia.

  • Determination of glomerular filtration rate, a spin off aftercontrast-enhanced computed tomography among criticallyill patients − proof of concept
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • Background Recently, Gong et al. (Gong et al. 2022) showed, in nine heathy subjects, that plasma clearance of high doses of iohexol given as contrast enhanced computed tomography (CT) could be used for determination of glomerular filtration rate (GFR). We utilized high doses of iohexol from angiographic or other contrast enhanced CT given to critical ill patients for calculation of GFRiohexol and compared these data with standard low dose iohexol GFR determinations.Method Patients at intensive care units (ICUs) in Southeast Sweden intended for radiographic investigations that included injection of 45-120 ml of iohexol (Omnipaque) were included, and the concentration of iohexol in plasma was measured by HPLC. Iohexol clearance was calculated by the method of Bröchner-Mortensen. The following days was iohexol clearance determined using the standard low dose of 5 mL of iohexol. Sixteen patients admitted to ICUs were included in this pilot study.Results GFR after high dosing of iohexol at contrast enhanced CT could be measured for all sixteen critically ill patients. Patients with normal or increased renal function had neglectable iohexol concentrations the day following the CT scan. There was excellent correlation between GFR determination with high and standard low iohexol dosing among these 6 patients. Ten patients had decreased renal function and delayed elimination of iohexol, thus was not GFR measurement with low dose iohexol possible to analyse the day after CT scan with high dose iohexol.Conclusion This pilot study showed that GFR can be measured after high doses of iohexol at enhanced CT and compare well with the standard low dose of iohexol clearance determinations.
