Background: PYY is a gut hormone that physiologically inhibits appetite. Currently only radioimmunoassay (RIA) techniques are available for its estimation. The aim of the study was to evaluate our in-house assay for precision, detection limit, interference of haemolysis, suitability of serum versus plasma and biological variation within one subject.Method: All samples were obtained from one subject on two occasions following an over night fast and the co...

Background: Changes in gut hormone levels after laparoscopic sleeve gastrectomy (LSG) has been proposed as a possible mechanism that explains the long-term weight loss and the improvement in glucose homeostasis after bariatric operations. In this prospective study we evaluated the changes in the fasting and postprandial levels of glucagon like peptide-1 (GLP-1), peptide YY (PYY), insulin and glucose during the first postoperative year after LSG.Methods: ...

Background: Adrenal venous sampling (AVS) is considered the gold standard for lateralisation of aldosterone production in patients with primary aldosteronism (PA). However, in some patients AVS is not technically successful and management may depend on radiological findings.Aim: To determine 1) the success rate of AVS and 2) the outcomes after surgery related to the lateralisation modality.Method: 156 patients were included who pre...
