Obesity is associated with increased and dysfunctional white adipose mass. In the past, pharmacological approaches have not yielded significant results in terms of stable weight loss. Glucagon-like peptide 1 receptor (GLP-1R) agonists (GLP-1RA) used for the treatment of type 2 diabetes have more recently been proposed as anti-obesity drugs due to their relevant effects on weight loss. Furthermore, dual agonists engaging both GLP-1R and glucagon receptor (GCGR) are under invest...

Recent guidelines on diabetes treatment provide that bariatric surgery should be the most logical & cost-effective means of controlling Type 2 diabetes.Objectives: To compare laparoscopic mini-gastric bypass vs laparoscopic sleeve gastrectomy regarding the efficacy of control of D.M in obese patients.Summary: A randomized controlled study conducted on 60 obese patients with type 2 D.M divided into, group (1): 30 patients treate...

The leptin/melanocortin pathway plays a critical role in hypothalamic control of food intake. Variants in the genes involved in this pathway, such as leptin (LEP), its receptor (LEPR), proopiomelanocortin (POMC) or proconvertase 1 (PCSK1) are associated with early-onset severe obesity and endocrine abnormalities especially in case of homozygosity. Heterozygous variants in the melanocortin-4 receptor (MC4R) gene are associated with an increased risk of severe obesity. The aim i...

Background: Interleukin (IL)-1 antagonism decreases systolic blood pressure in obese individuals. However, the underlying mechanism is unknown. Based on experimental data in animals we hypothesised a blood-pressure lowering effect of IL-1-antagonism via modulation of the renin-angiotensin-aldosterone system (RAAS).Methods: In this post-hoc explorative study, we examined short- (2 days) and long-term effects (4 weeks) of IL-1 antagonism (anakinra/Kineret<...

Introduction: Leptin is a well-known adipokine which has a critical role in the regulation of body weight, body fat mass, appetite, and food intakes. Energy-supplying nutrients such as carbohydrates is a dietary-related factor which has potential effects on plasma leptin levels. The effect of habitual carbohydrates intake on leptin gene expression was limited only in animal studies. The current study aimed to investigate the association of habitual carbohydrate intake with lep...

Background and aims: Obesity is a chronic multifactorial disease characterized by an excessive accumulation of body fat resulting from an imbalance between energy intake and caloric expenditure. Uncoupling protein 2 (UCP2) is located in the inner mitochondrial membrane and plays an important role in the regulation of energy expenditure. NLR family, pyrin domain-containing 3 (NLRP3) inflammasome seems to have a key role in obesity-induced inflammation through production of the ...

Background: Growth hormone (GH) potently stimulates lipolysis, and after GH exposure, levels of serum free fatty acids (FFAs) increase in a distinct temporal pattern characterized by a 1-hour lag phase and a peak after 3 hours followed by a gradual return to baseline. This effect predominantly operates during fasting and promotes utilization of lipids from adipose tissue (AT) at the expense of glucose and protein. Prolonged fasting also downregulates the expression of the G0/G...

Background: Postprandial hypoglycemia is an increasingly recognized complication after bariatric surgery. Its hallmark is a pronounced glycemic rise after carbohydrate ingestion followed by an exaggerated hyperinsulinemic response. Recent studies have shown that IL-1β contributes to postprandial stimulation of insulin. Furthermore, inhibition of SGLT2 reduces excessive plasma glucose increase. Therefore, we investigated whether inhibition of IL-1β with the IL-1 recep...

Background: Men with obesity often have low total and, with increasing adiposity, also free testosterone (T) levels, which can partially restore when they lose weight. Although this is in part explained by lower sex-hormone binding globulin (SHBG) production and hypothalamic-pituitary downregulation, it is still not fully unraveled whether changes in androgen metabolization contribute to this phenomenon.Aim: Investigating metabolisation of sex steroids d...

Introduction: Identification of early responders is widely used in pharmacotherapy for weight loss to minimize unnecessary exposure to risks and unnecessary expenses. Gelesis Loss Of Weight (GLOW; NCT02307279), a multicenter, double-blind, placebo-controlled pivotal study, demonstrated that Gelesis100 offers a compelling new potential approach in the management of overweight and obesity.Objective: A post-hoc area under the curve (AUC) for the receiver op...

Aim of the study was to estimate the effect of complex 3-week treatment with 4 kinesiotherapy methods on body weight loss and muscle function in patients with obesity.Material and methods: 80 men and women aged 21-69 years old with alimentary obesity were enrolled in the study (mean age 52.4±11 years, weight 111.3±24.5 kg, BMI 40.3±8.1 kg/m2, waist circumstance WC 113.4±16 cm, hip circumstance HC 124.2±16 cm). The comp...

Introduction: In overweight and obesity energy unbalance is responsible for the accumulation of ectopic fat. Excess energy and metabolic alterations, namely insulin resistance, may favor ectopic fat depositions. However, the role played by dietary factors, especially the pro-inflammatory properties of dietary patterns, in ectopic fat storage is not thoroughly understood. The aim of our study was to investigate the association between the Dietary Inflammatory Index (DII) and di...
