Background: Rapid and accurate risk stratification in patients with community-acquired pneumonia (CAP) is an unmet clinical need. Cortisol to DHEA ratio was put forward as a prognostic marker in sepsis. We herein validated the prognostic value of DHEA and DHEAS and of cortisol/DHEA- and cortisol-DHEAS – ratios, respectively, in patients with CAP as the most common (disease resulting) sepsis-defining illness.Methods: We assessed clinical parameters a...

Objective: The German KIMS Database is a national surveillance study for evaluation of efficacy and safety of growth hormone (GH) replacement therapy in adults with GH deficiency (GHD) in clinical practice.Patients: The analysis was performed using data of 1425 consecutively documented adult patients (777 men, 648 women) with GHD enrolled in KIMS Germany. The present report examined baseline and long term data (>48 months, range: 48–161 month) f...

Glycogen storage disease type 1 (GSD1) is a rare inherited defect of endogenous glucose production. While children present with severe hypoglycemia the propensity for hypoglycemia may decrease with age in these patients. It was the aim of this study to elucidate the mechanisms for milder hypoglycemia symptoms in grown up GSD1 patients. Four patients with GSD1 (BMI: 23.2±6.3 kg/m2, age: 21±3 yr) and four healthy controls matched for BMI (23.1±3.0 kg/m<...

Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant disorder characterised by the combined occurrence of tumours of the parathyroids, pancreas and pituitary. The MEN1 gene, which is located on chromosome 11q13 and encodes a 610 amino acid protein (menin), belongs to the class of tumour suppressors. To investigate the role of menin in tumour suppression, three different mouse models have been generated through targeted disruption of the Men1 gene. ...

Background: Serum soluble alpha klotho (sαKL) is a circulating protein which had been shown to be very high in active acromegaly, and significantly reduced after disease control. Therefore, sαKL has been suggested as a new biomarker for growth hormone (GH) excess. In this study, we aimed to evaluate the impact of short-term stimulation and suppression of GH and acute modulation of glucose metabolism on sαKL concentrations.Methods: Serum s&...

Rationale: The Aldosterone:Renin ratio (ARR) is commonly used for patients fulfilling screening criteria for primary hyperaldosteronism (PA), followed by confirmatory testing. Reference intervals for interpretation of the ARR vary in accordance with local population and assay 1. While ARR provides high sensitivity for PA, this is compromised by low specificity, further compounded by medication interference. However, additional variables may improve the specificity of ARR as a ...

Introduction: Diagnostic imaging of neuroendocrine tumors (NETs) is the domain of somatostatin receptor (SSTR) agonists as well as FDG PET/CT in dedifferentiated tumors. SSTR also serves as target for receptor directed peptide therapy. More recently, specific ligands targeting the chemokine receptor 4 (CXCR4) were introduced potentially offering an additional theranostic option in NETs. Here we evaluated the CXCR4 expression using 68Ga-Pentixafor PET/CT in NET patie...

Hypoparathyroidism is a rare endocrine deficiency due to inadequate amounts of parathyroid hormone (PTH) and is characterised by hypocalcaemia and hyperphosphataemia. Current management regimens with large amounts of oral calcium and active vitamin D do not adequately control mineral homeostasis and can lead to complications in many patients. The phase III REPLACE and RELAY clinical trials established the efficacy and safety of once-daily s.c. injection of r...

ObjectivesThere is a paucity of real-world studies analyzing comorbidities, lab testing and treatment patterns of patients with chronic hypoparathyroidism (cHP). This study describes a large cohort of cHP patients identified using a diagnosis-based approach from a US claims database.MethodsThis retrospective study was conducted using a large (130 million individuals) claims database (HealthVerity Closed Payer...

ObjectivesThere is a paucity of real-world studies on the clinical burden and practice patterns associated with chronic hypoparathyroidism (cHP). This study assesses the comorbidities, treatment and lab testing patterns in cHP patients identified using surgery-based criteria.MethodsThis was a retrospective study conducted using a large (130 million individuals) US claims database (HealthVerity Closed Payer Cl...
