Background: Phaeochromocytoma and paraganglioma (PPGLs) are rare neuroendocrine tumours arising from the adrenal medulla and paraganglia. Biochemical assessment relies on demonstrating elevated concentrations of catecholamines and their metabolites. Analytical methods for catecholamine and metanephrine measurement vary in sensitivity and specificity. We reviewed our biochemical work-up in order to optimise patient diagnosis.Methods: This retrospective au...

Introduction: Graves’ disease is the commonest cause of hyperthyroidism accounting for 80% of all cases. The first line treatment for Graves’ disease in the UK is medical therapy, most frequently using a ‘dose-titration’ regimen. Currently, there is a lack of guidance to aid clinicians in carrying out optimal dose-titration of carbimazole, resulting in a risk of under- or over-treatment. Thus, we aimed to develop a carbimazole dosing-algorithm for the medic...

Context: Identification of risk factors predicting relapse in patients with hyperthyroidism of Graves’ disease after the first cycle with standard thyreostatic therapy [ATD] is important to guide therapeutic options.Objective: We performed a systematic review and meta-analysis to study predictors for risk of relapse after the first treatment episode with ATD in patients with Graves’ disease induced hyperthyroidism.Data so...

Purpose: To investigate the kinetics of adrenocorticotropin (ACTH) following oral metyrapone administration and describe differences between ACTH-deficient and non ACTH-deficient subjects.Methods: Patients from a tertiary endocrine center at a University Hospital in Munich, Germany, were tested. Metyrapone (Metopirone, HRA Pharma, France) was administered with a dosage of 40 mg/kg bodyweight at 0800 h. Consecutive levels of ACTH were determined at 0, 60,...

Introduction: Regardless of improvements in MRI, up to 20% of ACTH-secreting pituitary tumors are only identified at surgical exploration. The objective was to estimate whether there is any difference in blood vessels and the subsequent ability to uptake contrast agent in visualized micro-adenomas as compared to non-visualized on MRI ACTH-secreting pituitary tumors.Materials and methods: Retrospective evaluation of ACTH-positive pituitary tumors from pat...

Background: Type 2 diabetes (T2D) is a progressive disease. The gut microbiota has recently been identified as a new potential diabetes risk factor.Design: To investigate the gut microbiota composition in association with the dietary patterns in patients with different glucose tolerance we analyzed 92 patients: with normal glucose tolerance (n=48), prediabetes (n=24) and T2D (n=20). Metagenomic analysis was performed using 16Sr...

The aim: To establish unfavorable genetic polymorphisms on the development of comorbidity of DM2 and EH in Ukrainian population and to evaluate the effectiveness of α-lipoic acid appointment (α-LC) in complex therapy in patients with 3-4 crossed unfavorable genetic polymorphisms.The primary examination of 167 patients with DM2 in combination with EH showed that A/C and C/C genotypes of AGTR1, Pro/Pro genotype of PPARγ2, Arg/Arg ...

Introduction: Acromegaly is a chronic disorder caused by growth hormone (GH) hyperproduction which leads to significant morbidity and mortality primarily due to cardiovascular and respiratory complications. Pituitary adenoma is the main cause of GH’s hyperproduction. By current guidelines transsphenoidal surgery (TSS) is the first-line treatment in acromegaly patients.Aim: To evaluate the results of TSS in acromegaly patients 6 months after surgery....

Objective: Whether additional immunosuppressive drugs to standard treatment with thyreostatic drugs reduce the risk for relapse in Graves’ disease is not well understood. We performed a systematic review and meta-analysis to study the effects of immunosuppressive drugs on relapse rate and treatment effect of patients with hyperthyroidism due to Graves’ disease.Methods: We searched PubMed, EMBASE and Cochrane in July 2015 for randomized-controll...

The nodular goiter is the most prevalent thyroid disorder. Its prevalence increases with age and reaches over 70%. The aim of the study was to compare the nodule prevalence in two population-based studies, carried in Bulgaria in 2006 and 2012.Material and methods: Two thousand four hundred and two subjects (1347 female and 1053 male, age range 20–94 years) were included in 2006 and 2022 (1073 female and 949 male, 20–88 years) in 2012. All subje...
