- Quality of life (QoL) and psychosocial well-being are substantially impaired in patients with Cushing's disease (CD), not only at the acute illness stage but also after therapy; however, the reason for these impairments remains unclear. In this cross-sectional, patient-reported outcome study, we conducted a postal survey on psychosocial impairment and coping strategies in patients after surgical treatment of CD in three large tertiary referral centers. In total, 176 patients with CD completed a compilation of self-assessment inventories pertaining to depression (Hospital Anxiety and Depression Scale, HADS), QoL (Short Form SF-36, Tuebingen CD; Tuebingen CD-25), coping style (Freiburg questionnaire on coping with illness, FKV-LIS), and embitterment (Bern Embitterment Inventory), on average 6.8 +/- 6.66 years after surgery. Regression analyses were performed to identify predictors of psychosocial impairment. At the time of the study, 21.8 % of patients suffered from anxiety, 18.7 % experienced an above-average feeling of embitterment, and 13.1 % suffered from depression. Maladaptive coping styles (FKV-LIS subscales depressive coping and minimizing importance) emerged as robust and strong predictors of psychosocial impairment in all inventories; while age, sex, and hydrocortisone intake failed to explain the variance in these measures. Similar to several studies in non-pituitary patient cohorts (e.g., patients with multiple sclerosis or lower back pain), our results indicate that psychosocial impairment in CD is significantly influenced by how the patient deals with the illness. Therefore, psychological training of positive coping styles could be a helpful complementary therapy in the overall treatment strategy of CD.

- Objective: GH deficiency (GHD) in adults is characterized by elevated body mass index (BMI), increased waist girth (WG) and increased fat mass (FM). Information about how these indicators of obesity affect the lipid profile and quality of life (QoL) of GHD subjects is scarce. It is also unclear how changes in these indicators brought about by GH replacement influence lipids and QoL. Design and methods: Adult GHD Subjects from the Pfizer International Metabolic Database were grouped according to BMI (n = 291 with BMI < 25 kg/m(2), n = 372 with BMI 25-30 kg/m(2), n = 279 with BMI > 30 kg/m(2)), WG (n = 508 with normal WG, n = 434 with increased WG) and FM (n = 357) and according to changes in these variables after 1 year of GH replacement. Serum IGF-1 concentrations, lipid concentrations and QoL using the QoL Assessment of GHD in Adults questionnaire were assessed at baseline and after 1 year of treatment. Results: At baseline, total and low-density lipoprotein (LDL) cholesterol were similarly elevated in the BMI and WG groups, but high-density lipoprotein (HDL) cholesterol decreased and triglycerides increased with increasing BMI and WG. QoL was progressively poorer with increasing BMI and WG. After 1 year of GH replacement, total and LDL cholesterol and QoL improved in all BMI, WG and FM groups. Conclusions: Variables of obesity adversely affect the already unfavourable lipid profile in GHD Subjects by decreasing HDL cholesterol, but do not counteract the positive effect of GH replacement on LDL cholesterol. Similarly, QoL is influenced by obesity, but responds equally well to GH treatment independent of BMI, WG and FM.

- Objective: The aim of the present study was to clarify the relationship between GH deficiency (GHD) andsome cardiovascular risk factors and to analyse the effect of GH replacement therapy in a large numberof patients over a prolonged period of time.Design: Data for analysis were retrieved from KIMS (Pfizer International Metabolic Database). Serumconcentrations of total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein(LDL)-cholesterol and triglycerides were obtained from 2589 patients at baseline and from 1206patients after 1 and 2 years of GH replacement therapy. Body mass index (BMI), waist and hip, restingblood pressure and body composition were also measured.Results: At baseline, the unfavourable effects of GHD were most obvious in the lipid profiledemonstrating elevated mean total and LDL-cholesterol, in the increased waist circumference and theelevated BMI. The cholesterol concentration, BMI and body composition were significantly adverselyaffected by a number of factors, including age, sex and the use of anti-epileptic drugs. The therapeuticeffect of GH was essentially uniform across the whole population. GH replacement reduced significantlythe mean total and LDL-cholesterol, the waist circumference and the fat mass and was maintainedduring 2 years.Conclusions: This analysis of a large number of patients confirmed that GHD adults present with anincreased cardiovascular risk. The sustained improvement of the adverse lipid profile and bodycomposition suggests that GH replacement therapy may reduce the risk of cardiovascular disease andthe premature mortality seen in hypopituitary patients with untreated GHD.

Tidskriftsartikel (refereegranskat)abstract
- Background: To evaluate the cost-effectiveness of growth hormone (GH) treatment (Genotropin®) compared with no GH treatment in adults with GH deficiency in a Swedish societal setting.Methods: A Markov-type cost-utility simulation model was constructed and used to simulate, for men and women, morbidity and mortality for GH-treated and -untreated individuals over a 20-year period. The calculations were performed using current available prices concerning morbidity-related healthcare costs and costs for Genotropin®. All costs and treatment effects were discounted at 3%. Costs were expressed in Euro (1€ = 9.03 SEK). GH-treated Swedish patients (n = 434) were identified from the KIMS database (Pfizer International Metabolic Database) and untreated patients (n = 2135) from the Swedish Cancer Registry and the Hospital Discharge Registry.Results: The results are reported as incremental cost per quality-adjusted life year (QALY) gained, including both direct and indirect costs for GH-treated versus untreated patients. The weighted sum of all subgroup incremental cost per QALY was €15,975 and €20,241 for men and women, respectively. Including indirect cost resulted in lower cost per QALY gained: €11,173 and €10,753 for men and women, respectively. Key drivers of the results were improvement in quality of life, increased survival, and intervention cost.Conclusions: The incremental cost per QALY gained is moderate when compared with informal thresholds applied in Sweden. The simulations suggest that GH-treatment is cost-effective for both men and women at the €55,371 (SEK 500,000 - the informal Swedish cost-effectiveness threshold) per QALY threshold. © 2013 Bolin et al.; licensee BioMed Central Ltd.

Tidskriftsartikel (refereegranskat)abstract
- Context: The diagnosis of GH deficiency (GHD) in adults is based on provocative tests of GH release, all influenced by clinical factors. It is unknown whether the amount of residual GH reserve under the cutoff value has any physiological implication. Objectives: We used a large pharmacoepidemiological database of adult GHD (KIMS) and tested the impact of confounding factors on GH release of no greater than 3 µg/liter after an insulin tolerance test (ITT) and evaluated its potential physiological role. Design, Settings, and Patients: A total of 1098 patients fulfilled the criteria of having a GH peak of no greater than 3 µg/liter during ITT as well as documented IGF-I levels. Outcomes: The impact of underlying hypothalamic-pituitary disease, age, gender, body weight, as well as treatment modalities such as irradiation on peak GH level to ITT was evaluated, and the correlations between GH peak and targets of GH action were analyzed. Results: The GH response to ITT was regulated by gender, age, and the number of additional pituitary deficiencies. In a multivariate evaluation, the extent of hypothalamic-pituitary dysfunction was the most important single predictor of GH peak in ITT. GH peaks in ITT were positively related to IGF-I levels and high-density lipoprotein-cholesterol, as well as inversely to triglycerides. Conclusions: Even in adult severe GHD, GH release appears to be regulated by factors defined to play an important role in normal GH secretion. The impact of very low GH release on IGF-I and lipid parameters indicates a persistent physiological role of low GH concentrations in severely affected patients with GHD.

- PurposeTo explore the effects of pegvisomant (PEGV) on glucose metabolism in patients with acromegaly within ACROSTUDY, an international, observational, prospective safety surveillance study.MethodsPatients were retrospectively divided into two cohorts, with (DM group) or without diabetes mellitus (no-DM). Parameters of glucose metabolism and IGF-I values were analyzed yearly both cross-sectionally for 4 years (yrs) and longitudinally at 1 and 4-5yrs of PEGV treatment.ResultsAmong 1762 patients, 510 (28.9%) had DM before PEGV start. At cross-sectional analyses, in the DM group mean blood glucose was 140.058.7mg/dl at baseline, 116.4 +/- 44.8mg/dl at year 1 and 120.0 +/- 44.3mg/dl at yr 4. Mean HbA1c was 6.6 +/- 1.2 % at yr 1 vs. 7.0 +/- 1.4 % at baseline. HbA1c was above 6.5% in 61.9% at baseline and ranged from 45.4 to 53.8% at subsequent yearly time points. At the 4-yr longitudinal analysis, in the DM group (n=109), mean blood glucose decreased by 20.2mg/dl at yr 4, mean HbA1c was 7.0 +/- 1.5% at baseline vs. 6.8 +/- 1.4%. Patients achieved IGF-I normalization in 52.1% and 57.4% of cases in the DM and no-DM groups, respectively at 1 year. The mean daily PEGV dose (mg/day) was higher in the DM group (18.2 vs. 15.3) while the absolute change of IGF-I values from baseline was similar in both groups. PEGV was well tolerated in both groups without any unexpected AEs.Conclusions p id=Par4 Patients with DM had a moderate decrease in mean fasting glucose values during PEGV treatment.

Forskningsöversikt (refereegranskat)abstract
- The concept of health-related quality of life (HrQoL) reflects the subjective perception of health and includes aspects of well-being and functioning in physical, emotional, mental and social life domains. Nowadays, HrQoL has become a relevant treatment outcome from epidemiological and clinical perspectives and is also broadly employed in health economic analyses. To assess HrQoL generic as well as condition-specific instruments are used. The former are applicable to a wide range of health conditions and aim at measuring HrQoL across different conditions. The latter focus on capturing the impact of a specific disease. Although HrQoL research in adults is now well-advanced, there are still open questions regarding how to assess HrQoL in pediatric conditions, such as short stature. Eight generic (one chronic-generic) and seven condition-specific (one treatment-specific) instruments used in HrQoL research in short stature of youth are described. Additionally, this mini review identifies a need for further research and indicates potential directions.
