- ContextPrader–Willi syndrome (PWS) is associated with several hypothalamic-pituitary hormone deficiencies. There is no agreement on the prevalence of central adrenal insufficiency (CAI) in adults with PWS. In some countries, it is general practice to prescribe stress-dose hydrocortisone during physical or psychological stress in patients with PWS. Side effects of frequent hydrocortisone use are weight gain, osteoporosis, diabetes mellitus, and hypertension—already major problems in adults with PWS. However, undertreatment of CAI can cause significant morbidity—or even mortality.ObjectiveTo prevent both over- and undertreatment with hydrocortisone, we assessed the prevalence of CAI in a large international cohort of adults with PWS. As the synacthen test shows variable results in PWS, we only use the metyrapone test (MTP) and insulin tolerance test (ITT).DesignMetyrapone test or ITT in adults with PWS (N = 82) and review of medical files for symptoms of hypocortisolism related to surgery (N = 645).SettingOutpatient clinic.Patients or Other ParticipantsEighty-two adults with genetically confirmed PWS.Main Outcome MeasureFor MTP, 11-deoxycortisol > 230 nmol/L was considered sufficient. For ITT, cortisol > 500 nmol/L (Dutch, French, and Swedish patients) or > 450 nmol/L (British patients) was considered sufficient.ResultsCentral adrenal insufficiency was excluded in 81 of 82 patients. Among the 645 patients whose medical files were reviewed, 200 had undergone surgery without perioperative hydrocortisone treatment. None of them had displayed any features of hypocortisolism.ConclusionsCentral adrenal insufficiency is rare (1.2%) in adults with PWS. Based on these results, we recommend against routinely prescribing hydrocortisone stress-doses in adults with PWS.

- To assess the safety (particularly the occurrence of malignancies) of growth hormone (GH) replacement (Omnitrope®) in adults with GH deficiency, using data from the ongoing PATRO Adults post-marketing surveillance study. Methods: PATRO Adults is being conducted in hospitals and specialized endocrinology clinics across Europe. All enrolled patients who receive ⩾1 dose of Omnitrope® are included in the safety population. Malignancies are listed as adverse events under the MedDRA System Organ Class ‘neoplasms, benign, malignant and unspecified (including cysts and polyps)’. Results: As of July 2018, 1293 patients had been enrolled in the study and 983 (76.0%) remained active in the study. Approximately half [ n = 637 (49.3%)] of the patients were GH treatment-naïve on study entry. The majority of enrolled patients had multiple pituitary hormone deficiency ( n = 1128, 87.2%). A total of 41 on-study malignancies were reported in 33 patients (2.6%; incidence rate 7.94 per 1000 patient-years). The most common cancers were basal cell carcinoma ( n = 13), prostate ( n = 6), breast, kidney and malignant melanoma (each n = 3). Treatment with Omnitrope® was discontinued following diagnosis of malignancy in 16 patients. The tumors occurred after a mean of 79.4 months of recombinant hormone GH (rhGH) treatment overall. Conclusion: Based on this snapshot of data from PATRO Adults, Omnitrope® treatment is tolerated in adult patients with GH deficiency in a real-life clinical practice setting. Our results do not generally support a carcinogenic effect of rhGH in adults with GH deficiency, although an increased risk of second new malignancies in patients with previous cancer cannot be excluded based on the current dataset.
