Introduction: More data are needed to confirm the long-term safety of recombinant human GH (rhGH) in adult patients with severe GH deficiency (GHD), particularly with regard to diabetogenic potential. PATRO Adults is an ongoing observational, multicentre, open, longitudinal study of Omnitrope, being conducted in hospitals and specialised endocrinology clinics across Europe. Here, we present safety data from an interim analysis.Methods: Eligible patients ...

Introduction: Treatment with dopamine agonists in patients with PRL adenomas has been associated with weight loss in short-term studies. However, long-term studies on weight changes are lacking. Taq1A is a restriction fragment length polymorphism considered as a gene marker for the D2DR gene. The presence of at least one A1 allele is linked to reduced brain dopaminergic activity due to reduced receptor binding and lower density of the dopamine two receptor.<p clas...

Introduction: Discontinuation of GH therapy in patients with COGHD after attainment of final height has been associated with impaired somatic development, altered peak bone mass and cardiovascular risk factors. A well-managed transition of care between paediatric and adult health services can improve the clinical and social outcomes in adolescents with GHD.Objective: To assess the quality of the transfer between children and adult medical services in our...

Hypoxia inducible factor-1alpha (HIF-1α) is a transcription factor regulating expression of many genes related to oxygen homeostasis in response to hypoxic stress. RSUME is a sumoylation enhancer, which was recently cloned from a pituitary cell line with an increased tumorigenic and angiogenic potential. It has been shown that RSMUE is induced by hypoxia and enhances the sumoylation of HIF-1α. Although many studies demonstrated that the level of HIF-1α is remark...

Background: Low testosterone levels in men occur with increasing age and are associated with increased morbidity, particularly metabolic syndrome, and mortality. As the prevalence of hypogonadal testosterone levels has not been assessed in the primary care setting in Europe, we aimed to investigate the prevalence of low testosterone levels in this setting, and the patient characteristics and comorbidities associated with it.Methods: We measured testoster...

Objectives: Acromegaly is associated with elevated cardiovascular morbidity. Medical treatment of acromegaly does not only lead to a normalisation of the somatotroph axis, but can also negatively influence cardiovascular risk factors and comorbidities.Methods: In a cross-sectional study, we evaluated cardiovascular risk markers (glucose, HbA1c, triglycerides, cholesterol, HDL, LDL, lipoprotein a, homocystein, CRP) in relation to biochemical control and m...

Introduction: Omnitrope® (Sandoz) is a recombinant human growth hormone (rhGH) and was the first biosimilar medicine approved by the European Medicines Agency. PATRO Adults is an international, longitudinal, non-interventional study of the long-term safety and efficacy of Omnitrope® in adults treated in routine clinical practice. The study provides data on the long-term safety of rhGH in adult patients with severe GH deficiency (GHD). Here we pr...

Corticotrophin-releasing hormone (CRH) stimulation test is used in the differential diagnosis of Cushing’s syndrome. Cushing’s disease tumours carry somatic driver activating mutations in the ubiquitin-specific-protease 8 (USP8) gene in almost half of the cases. The aim of the present study was to examine whether the USP8 mutational status in Cushing’s disease tumours influences the response to the CRH stimulation test. We did a monocentric, re...

The chemotherapeutic agent temozolomide (TMZ) has been applied for the treatment of pituitary carcinomas, atypical pituitary adenomas and prolactinomas resistant to dopamine agonist treatment with considerable success. Both shrinkage of the tumors and a drop of excessive hormone production were observed in TMZ-responsive patients. In order to clarify whether the TMZ-induced suppression of hormone secretion was a consequence of tumor shrinkage or caused by direct effects on hor...

Introduction: PATRO adults is an ongoing, international, open, longitudinal, non-interventional study of the long-term safety and efficacy of recombinant human GH (rhGH; Omnitrope, Sandoz). The study will provide further data on the long-term safety of rhGH in adult patients with severe GH deficiency (GHD). Here, we present safety data from an interim analysis.Methods: Adults who are receiving treatment with Omnitrope and who have provided informed conse...
