Objective: Therapeutic glucocorticoids (GCs) are commonly used in the treatment of chronic inflammatory disease. Unfortunately, their long-term administration is associated with deleterious systemic side effects including muscle atrophy. 11 beta-hydroxysteroid dehydrogenase type 1 (11βHSD1) activates glucocorticoids within muscle, is increased with inflammation, and has previously been shown to mediate GC induced muscle wasting. We examined the role of 11 beta-hydroxyster...

Objective: Therapeutic glucocorticoids (GCs) are used to treat chronic inflammatory disease, due to their anti-inflammatory effects. Despite their efficacy, chronic exposure to GCs elicits undesirable side effects, including muscle atrophy. 11 beta-hydroxysteroid dehydrogenase 1 (11β-HSD1) activates GCs within muscle, is induced by inflammation, and has previously shown to drive GC-induced muscle wasting. We examined the role of 11β-HSD1 in mediating muscle wasting i...

Introduction: Muscle atrophy is a major clinical complication of acute exacerbations (AE) in chronic obstructive pulmonary disease (COPD). The enzyme 11 beta-hydroxysteroid dehydrogenase 1 (11β-HSD1) activates glucocorticoids (GCs) within muscle, is induced by inflammation, and has been shown to contribute towards GC-induced muscle wasting. In this study, we examined the role of 11β-HSD1 in this context using a murine model of COPD-AE in animals with transgenic globa...

Germline mutations in the succinate-dehydrogenase subunits A, B, C, and D (SDHA/B/C/D) predispose to development of the phaeochromocytoma-paraganglioma (FPGL) syndromes. SDHC and SDHD are anchoring proteins located in the inner mitochondrial membrane. The SDH complex has two major roles in energy production it is part of the tricarboxic acid cycle catalysing the oxidative dehydrogenation of succinate coupled to the reduction of ubiquinone. It is also the complex II component o...

Background: Thyroid-stimulating hormone (TSH) might influence bone mineral density (BMD) through its regulation of the thyroid hormones thyroxine (T4) and triiodthyronine (T3). Direct effect of TSH on bone turnover, mediated through its receptors on both osteoblast and osteoclast precursors, has been suggested. We wanted to explore the relationship between serum TSH, fT4 and BMD in women with different TSH levels after a long-term observation of thyroid function and bone statu...

Introduction: Surgery is the established first line treatment in adrenocortical carcinoma (ACC). For benign adrenal tumours, laparoscopic adrenalectomy (LA) has become the treatment of choice. However, the role of LA in ACC remains highly controversial. Data from the German ACC Registry were used to evaluate the technical feasibility of LA in ACC and to compare the long-term outcome after LA with the results of open adrenalectomy (OA).Methods: Out of 521...

Background: Craniopharyngiomas (CP) are benign brain tumours presenting in childhood treated by tumour resection together with radiotherapy. In about half of the cured patients hypothalamic damage leading to eating disorders and obesity as well as to hypopituitarism, necessitating consequent hormone substitution therapy, is observed. Bariatric surgery is an efficient treatment strategy for morbid obesity. However, so far it is unknown, whether oral hormone substitution is hamp...

Objective: The role of surgery for recurrent adrenocortical carcinomas (ACC) is not well defined. Therefore, we evaluated the outcome after surgery for tumor recurrence in patients from the German ACC Registry.Methods: Only patients with first recurrence after initial R0 resection were investigated. Progression–free and overall survival (PFS, OS) after first recurrence were analyzed by Kaplan–Meier method. Cox proportional hazards regression mo...

Adrenocortical carcinoma (ACC) is a rare disease with poor prognosis. Accordingly, in many cases, the attending doctors have no previous experience with the disease. The aim of our study was to evaluate the quality of care in a large number of patients with ACC in Germany. Data from 263 adult patients of the German ACC registry were analyzed with regard to the following parameters: time to diagnosis, hormonal assessment, imaging, histopathological documentation, follow-up. The...

Even after complete resection, patients with ACC have a high risk of relapse, and adjuvant treatment with mitotane is frequently recommended. Although mitotane has significant efficacy in this setting, it is associated with a wide range of side effects. As survival is highly variable, prognostic factors are of great interest to better guide adjuvant therapy after radical resection.We analyzed clinical and histopathological data of patients without distan...
