Background: Food intake and body weight are in a constant sense of balance, which is tightly regulated. The central control of appetite by the hypothalamus and areas in the brainstem has been established. The peripheral regulation of appetite via gut hormones has also been alluded to – previous studies have shown PYY and ghrelin hormones to be altered in obesity. Glucagon-like peptide-1 is a gut hormone released from L-cells in the distal ileum and colon. It has been impl...

Objectives: The long-term outcome of bariatric surgery on renal function in the morbidly obese renal transplant recipient is still unknown. We describe three cases of morbidly obese renal transplant recipients who have subsequently undergone bariatric surgery.Patient 1: A 44-year-old man (BMI 42.2 kg/m2) had received a renal transplant for chronic renal disease secondary to childhood reflux nephropathy. Laparoscopic Roux-en-Y gastric bypass re...

Aims/objectives: Obesity and prediabetes are risk factors for developing T2D. 5–10% weight-loss can reduce risk of developing T2D by >50%. The 3-year part of this phase 3 trial investigated effects of liraglutide 3.0 mg, as adjunct to diet+exercise, in delaying onset of T2D over 3 years, body-weight and cardiometabolic risk factors in adults with obesity or overweight with comorbidities, and diagnosed with prediabetes at screening.Methods: Indiv...

Background: The effect of Roux-en-Y gastric bypass (RYGB) on diabetic kidney disease (DKD) is unclear. We used a Zucker diabetic fatty rat (ZDF) model of DKD to determine the effect of RYGB on histopathological markers of DKD, proteinuria, and MCP1 excretion.Methods: ZDF rats underwent RYGB (n=15) or sham surgery (n=14) at 18 weeks of age. Eight sham operated animals were food restricted to match the weight loss of the RYGB group (body-...

Introduction: Obesity related glomerulopathy (ORG) is an emerging epidemic alongside increasing incidences of obesity. ORG pathophysiology has not been explored despite poor prognosis in untreated patients. MCP-1, MIF, CCL-18 and CCL-15 are novel cytokines that may be pathologically involved in obesity-induced renal injury and explored in this study.Methods: Blood pressure, urine and blood samples were collected from 34 morbidly obese patients before and...

Objective: Rimonabant has been shown to reduce weight, free androgen index (FAI) and insulin resistance in obese patients with PCOS compared to metformin. Metformin has also been shown to maintain the weight loss and enhance the metabolic and biochemical parameters achieved by treatment with rimonabant. We have determined the effect of rimonabant on the incretin hormones in patients with PCOS.Design: A randomized open labelled parallel study of metformin...

Objective: Time-restricted eating (TRE) represents a novel intervention that may improve insulinaemia and reduce weight, but is untested in polycystic ovarian syndrome (PCOS). In a randomised interventional study (NCT05126199), we investigated the feasibility of TRE in PCOS. Secondary objectives included effects on insulin and metabolic indices.Methods: Participants were randomised to 12-week TRE (18h fast/6h eating wind...

Background: Growing evidence suggests that hypothalamic lipid sensing plays a key role in controlling food intake, fat deposition and energy balance and that its dysregulation could lead to obesity and type 2 diabetes (T2D). Recent investigations reported that sphingosine-1-phosphate (S1P) is involved in the hypothalamic control of energy homeostasis. Intra-cerebroventricular administration of S1P decreased food intake and increased energy expenditure in rodents.<p class="...
