Introduction: The role of hormones and their underlying mechanisms in the development of osteoporosis are complex and not completely understood. Serum SHBG concentration is increased in older men and may be correlated with reduced bone mineral density and increased fracture risk. However, there is little data on exact relation of BMD with 24-h mean concentration and circadian rhythm of SHBG.Methods: We measured 24-h mean SHBG concentration in 3 groups of...

Background: NF1 and MEN2 are rare conditions known to associate with bilateral phaeochromochtomas. We describe, with relevant associated radiology, a NF1 patient developing a series of neuroendocrine tumours including bilateral phaeochromocytomas.Clinical case: A 39-year-old lady presented with long standing episodic abdominal pain, diarrhoea, palpitation and sweating. Past history includes first arch syndrome and NF1 at teens and total thyroidectomy for...

Introduction: T2DM is one of the main causes of morbidity and mortality in the UK. Epigenetic mechanisms impact gene expression and could predispose individuals to a particular metabolic phenotype. We investigated association of LINE-1 methylation (a surrogate of global DNA methylation) with cardiometabolic parameters in a longitudinal cohort of T2DM patients.Methods: Global LINE-1 DNA methylation in blood-derived DNA samples from 795 (men 60%, women 40%...

Introduction: There is growing evidence of external factors modulating epigenetic modifications and their contribution to the development of obesity and T2DM. One of the epigenetic signatures is DNA methylation. We investigated whether a lifestyle intervention could influence DNA methylation of Brain derived neurotrophic factor (BDNF) in individuals with IGR, as BDNF is thought to play an important role in glucose metabolism.Methods: IGR participants (<e...

Background: Adult growth hormone deficient (AGHD) is associated with reduced bone turnover and reduced bone mineral density (BMD): factors improved by growth hormone replacement (GHR). Obesity is associated with reduced bone turnover but increased BMD. We investigated the impact of body mass index on parathyroid hormone (PTH), phospho-calcium metabolism and bone turnover in AGHD patients before and after GHR.Study design: Of 31 AGHD patients (15 obese pa...
