- Pharmacokinetic properties of cortisone acetate (CA) and hydrocortisone (HC) differ because CA needs to be converted into cortisol to become active.This work analyzed the metabolic consequences of switching CA to an equivalent daily dose of HC in patients with secondary adrenal insufficiency (SAI).This was a post hoc analysis from a prospective study including individuals with hypopituitarism receiving growth hormone replacement. Data were collected before and after a switch from CA to an equivalent dose of HC (switch group). Two control groups were included: patients continuing CA replacement (CA control group) and adrenal-sufficient hypopituitary patients (AS control group).The analysis included 229 patients: 105, 31, and 93 in the switch, CA control, and AS control groups, respectively. After the change from CA to HC, increases in mean body weight (1.2 kg; P < .05), waist circumference (2.9 cm; P < .001), body fat measured by dual-energy x-ray absorptiometry (1.3 kg; P < .001), and glycated hemoglobin (0.3%; P < .05) were recorded in the switch group. The increase in mean waist circumference was greater than in the AS control group (0.9 cm; P < .05). Mean body fat increased in the switch group but not in the CA control group (-0.7 kg; P < .05).A switch from CA to an equivalent dose of HC was associated with a worsened metabolic profile, suggesting that HC has a more powerful metabolic action than CA based on the assumption that 20 mg HC equals 25 mg CA.

- Objective: Little is known of the effects of long-term GH replacement on bone mineral content (BMC) and bone mineral density (BMD) in elderly GH deficient (GHD) adults.Design/Patients/Methods: In this prospective, single-centre, open-label study, the effects of 3-year GH replacement were determined in 45 GHD patients above 65 years of age and in 45 younger control GHD patients with a mean age of 39.5 (SEM 1.1) years. All patients had adult onset disease and both groups were comparable in terms of number of anterior pituitary hormonal deficiencies, gender, body mass index (BMI), and waist:hip ratio.Results: The mean maintenance dose of GH was 0.24 (0.02) mg/day in the elderly patients and 0.33 (0.02) mg/day in the younger GHD patients (p<0.01). The three years of GH replacement induced a marginal effect on total body BMC and BMD whereas femur neck and lumbar (L2-L4) spine BMC and BMD increased in both the elderly and the younger patients. The treatment response in femur neck BMC was less marked in the elderly patients (p<0.05 vs. younger group). However, this difference disappeared after correction for the lower dose of GH in the elderly patients using an analysis of covariance. There were no between-group differences in responsiveness in BMC or BMD at other skeletal locations.Conclusions: This study shows that GH replacement increases lumbar (L2-L4) spine and femur neck BMD and BMC in younger as well as elderly GHD patients. This supports that long-term GH replacement is useful also in elderly GHD patients.

- Objective: Few studies have determined the effects of more than 5-10 years of GH replacement in adults on body composition and cardiovascular risk factors. Design/patients: In this prospective, single-center, open-label study, the effects of 15 years of GH replacement on body composition and cardiovascular risk factors were determined in 156 hypopituitary adults (93 men) with adult-onset GH deficiency (GHD). Mean age was 50.5 (range 22-74) years at study start. Body composition was measured using dual-energy X-ray absorptiometry. Results: The mean initial GH dose of 0.55 (S. E. M. 0.03) mg/day was gradually lowered to 0.40 (0.01) mg/day after 15 years. The mean serum IGF1 SDS increased from -1.53 (0.10) at baseline to 0.74 (0.13) at study end (P<0.001 vs baseline). Lean soft tissue (LST) increased to 3% above the baseline level at study end (P<0.001). After a 9% decrease during the first year of treatment (P<0.001 vs baseline), body fat (BF) started to increase and had returned to the baseline level after 15 years. Serum levels of total cholesterol and LDL-cholesterol decreased and serum HDL-cholesterol level increased. Fasting plasma glucose increased from 4.4 (0.1) at baseline to 4.8 (0.1) mmol/l at study end (P<0.001). However, blood HbA1c decreased from 5.0 (0.1) to 4.6 (0.1) % (P<0.001). Conclusions: Fifteen-year GH replacement in GHD adults induced a transient decrease in BF and sustained improvements of LST and serum lipid profile. Fasting plasma glucose increased whereas blood HbA1c was reduced. European Journal of Endocrinology 168 745-753

Design/patients: In this prospective, single-centre, open-label study, the effects of 15 years of GH replacement on BMC and BMD, measured using dual-energy X-ray absorptiometry, were determined in 126 hypopituitary adults (72 men) with adult-onset GH deficiency (GHD). Mean age was 49.4 (range 22-74) years at the initiation of the study. Results: The mean initial GH dose of 0.63 (S.E.M. 0.03) mg/day was gradually lowered to 0.41 (0.01) mg/day after 15 years. The mean serum IGF1 SDS increased from -1.69 (0.11) at baseline to 0.63 (0.16) at the study end (P < 0.001 vs baseline). The 15 years of GH replacement induced a sustained increase in total body BMC (+5%, P < 0.001) and BMD (+2%, P < 0.001). Lumbar (L2-L4) spine BMC increased by 9% (P < 0.001) and BMD by 5% (P < 0.001). In femur neck, a peak increase in BMC and BMD of 7 and 3%, respectively, was observed after 7 years (both P < 0.001). After 15 years, femur neck BMC was 5% above the baseline value (P < 0.01), whereas femur neck BMD had returned to the baseline level. In most variables, men had a more marked response to GH replacement than women. Conclusions: Fifteen-year GH replacement in GHD adults induced a sustained increase in total body and lumbar (L2-L4) spine BMC and BMD. In femur neck, BMC and BMD peaked at 7 years and then decreased towards baseline values.

- Few studies have determined the effects of long-term growth hormone (GH) replacement on quality of life (QoL). This study investigated the effects of 7 years of GH replacement on QoL.A prospective, single-center, open-label study of 95 adults (mean age 52.8 years; 46 men) with adult-onset GH deficiency (GHD).QoL was measured using Quality of Life-Assessment for Growth Hormone Deficiency in Adults (QoL-AGHDA) and Psychological General Well-Being (PGWB) scores.The GH dose was gradually increased from 0.13 mg/day to 0.42 mg/day. IGF-I SD score increased from -1.49 at baseline to 0.35 at study end. The GH replacement induced sustained improvements in total QoL-AGHDA and PGWB scores. GHD women had a more marked improvement in total QoL-AGHDA score than GHD men after 5 and 7 years. Most of the improvement in QoL was seen during the first year, but there was a small further improvement also after one year as measured using QoL-AGHDA. All QoL-AGHDA dimensions improved, but the improvement in memory and concentration as well as tenseness occurred later than that of other dimensions. Correlation analysis demonstrated that the patients with the lowest baseline QoL had the greatest improvement in QoL.Seven years of GH replacement improved QoL with the most marked improvements in GHD women and in patients with low baseline QoL. Most, but not all, of the improvement in QoL was seen during the first year. Some QoL-AGHDA dimensions (memory and concentration, tenseness) responded at a slower rate than other dimensions.

- 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.

Forskningsöversikt (refereegranskat)abstract
- Women with hypopituitarism have various degrees of androgen deficiency, which is marked among those with combined hypogonadotrophic hypogonadism and secondary adrenal insufficiency. The consequences of androgen deficiency and the effects of androgen replacement therapy have not been fully elucidated. While an impact of androgen deficiency on outcomes such as bone mineral density, quality of life, and sexual function is plausible, the available evidence is limited. There is currently no consensus on the definition of androgen deficiency in women and it is still controversial whether androgen substitution should be used in women with hypopituitarism and coexisting androgen deficiency. Some studies suggest beneficial clinical effects of androgen replacement but data on long-term benefits and risk are not available. Transdermal testosterone replacement therapy in hypopituitary women has shown some positive effects on bone metabolism and body composition. Studies of treatment with oral dehydroepiandrosterone have yielded mixed results, with some studies suggesting improvements in quality of life and sexual function. Further research is required to elucidate the impact of androgen deficiency and its replacement treatment on long-term outcomes in women with hypopituitarism. The lack of transdermal androgens for replacement in this patient population and limited outcome data limit its use. A cautious and personalized treatment approach in the clinical management of androgen deficiency in women with hypopituitarism is recommended while awaiting more efficacy and safety data.

- Context: New therapeutic strategies have developed for the management of acromegaly over recent decades. Whether this has improved mortality has not been fully elucidated. Objective: The primary aim was to investigate mortality in a nationwide unselected cohort of patients with acromegaly. Secondary analyses included time trends in mortality and treatment patterns. Design: A total of 1089 patients with acromegaly were identified in Swedish National Health Registries between 1987 and 2013. To analyse time trends, the cohort was divided into three periods (1987–1995, 1996–2004 and 2005–2013) based on the year of diagnosis. Main outcome measures: Using the Swedish population as reference, standardized mortality ratios (SMRs) were calculated with 95% confidence intervals (CIs). Results: Overall SMR was 2.79 (95% CI: 2.43–3.15) with 232 observed and 83 expected deaths. Mortality was mainly related to circulatory diseases (SMR: 2.95, 95% CI: 2.35–3.55), including ischemic heart disease (2.00, 1.35–2.66) and cerebrovascular disease (3.99, 2.42–5.55) and malignancy (1.76, 1.27–2.26). Mortality decreased over time, with an SMR of 3.45 (2.87–4.02) and 1.86 (1.04–2.67) during the first and last time period, respectively (P=.015). During the same time periods, the frequency of pituitary surgery increased from 58% to 72% (P<0.001) and the prevalence of hypopituitarism decreased from 41% to 23% (P<0.001). Conclusions: Excess mortality was found in this nationwide cohort of patients with acromegaly, mainly related to circulatory and malignant diseases. Although still high, mortality significantly declined over time. This could be explained by the more frequent use of pituitary surgery, decreased prevalence of hypopituitarism and the availability of new medical treatment options. © 2018 European Society of Endocrinology Printed in Great Britain.

- Diabetes is a major risk factor for cardiovascular disease and death but its effect on outcomes in acromegaly is unknown.This work aimed to study whether diabetes affects morbidity and mortality in patients with acromegaly.A nationwide (Sweden), observational, matched-cohort study was conducted. Patients diagnosed with acromegaly between 1987 and 2020 were identified in the Swedish National Patient Registry and those with concomitant type 2 diabetes in the National Diabetes Registry and Drug Registry. The risk of overall mortality, and cardiovascular mortality and morbidity were estimated using Cox regression.The study included 254 patients with acromegaly and concomitant type 2 diabetes (ACRO-DM group) and 532 without diabetes (ACRO group). Mean (SD) age at baseline was 62.6 (11.4) and 60.0 (12.1) years (P = .004) and the mean (SD) duration of acromegaly was 6.8 (8.1) and 6.0 (6.2) years (P = .098) in the ACRO-DM and ACRO groups, respectively. Overall mean follow-up was 9.2 years. The unadjusted overall mortality rate per 1000 person-years was 35.1 (95% CI, 27.2-44.7) and 20.1 (95% CI, 16.5-24.3) in the respective groups. The hazard ratio (HR) for overall mortality adjusted for multiple confounders was 1.58 (95% CI, 1.12-2.23) in the ACRO-DM group compared with the ACRO group. Cardiovascular mortality (HR 2.11; 95% CI, 1.09-4.10) and morbidity (HR 1.49; 95% CI, 1.21-1.82) were also increased in the ACRO-DM group.The presence of diabetes in patients with acromegaly was associated with increased overall mortality as well as increased cardiovascular mortality and morbidity.
