Low glycaemic index (GI) diet and gut hormones such as glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) have been shown independently to reduce appetite. However, the direct relationship between a single meal of low or high GI and the levels of these hormones has not been studied. In this study we looked at the short term effects of a single low or high GI meal on plasma levels of GLP-1, PYY and insulin.King’s College London’s research ethi...

Generalised and periarticular osteoporosis are common features of inflammatory arthritides. These effects appear due to high levels of pro-inflammatory cytokines. 11beta-hydroxysteroid dehydrogenase type 1 (11b-HSD1) is an intracellular enzyme that generates active cortisol from inactive cortisone and is an important determinant of the effects of glucocorticoids on osteoblasts. In vitro, osteoblastic 11b-HSD1 expression is induced by pro-inflammatory cytokines. We thus ...
