In this study, we analyzed the association between serum leptin levels and non-small cell lung carcinoma (NSCLC). By examining English and Chinese databases, we identified potential relevant studies for statistical analysis. Human-associated case-control studies evaluating the association between serum leptin levels and NSCLC according to the random-effect model were retrieved and extracted dat...

INTRODUCTION Leptin, protein taking part in body mass regulation, might play a role in cancer cachexia development. The aim of the study was to measure leptin serum levels in cachectic, non-cachectic lung cancer patients, healthy controls and to correlate leptin concentration with nutritional status markers. MATERIAL AND METHODS 40 lung cancer patients were enrolled into the study: 20 with ca...

Ghrelin and leptin are two hormones that possess multiple functions, including appetite regulation, maintenance of the tissue homeostasis regulation proinflammatory cytokines. A few studies on serum ghrelin levels in autoimmune diseases have exhibited conflicting results. Therefore, present study aimed to investigate relationship between energy balance diseases. Serum were assessed 94 adult pat...

BACKGROUND The ob gene product leptin is secreted by fat cells and reflects the content of fat in the body. Leptin and insulin concentrations as well as body weight are interrelated and a direct correlation has been found between these concentrations in humans with normal renal function. Markedly elevated serum leptin concentrations have recently been reported in patients with chronic renal fai...

INTRODUCTION Leptin is a hormone secreted by adipocytes that plays an important role in regulating appetite and energy expenditure. Our aim was to evaluate serum leptin level in hemodialysis (HD) patients with or without chronic liver disease (CLD) and study the relationship between serum leptin level and bone mineral density in these groups of patients. METHODS we recruited 20 healthy volunt...

The mechanisms of the increased serum leptin in response to feeding are poorly understood. Therefore, we used metabolic labeling to directly assess leptin biosynthesis, secretion, and turnover in adipose tissue from 14 h-starved compared with fed 12-14 week old rats. Starvation decreased serum leptin (-47 +/- 7%), adipose tissue leptin content (-32 +/- 5%), and leptin secretion during 3 h of in...

 Background: Appetite is one of the main obesity-controlling factors that can be influenced by hormones, including leptin and ghrelin. This study aimed to determine the effects of zinc supplementation on the serum levels of leptin, ghrelin, C-reactive protein (CRP), and anthropometrical indices in obese individuals with increased appetite and zinc deficiency. Methods: This study was conducted a...

Abstract Background The role of adipokines such as leptin and adiponectin in regulating the immunity has been documented, however data concerning their consequence on multiple sclerosis (MS) Egyptian patients are deficient. aim this study is to demonstrate serum levels MS assess association with disease disability severity. A case–control including 60 subjects (30 30 age, sex body mass index-ma...

introduction: leptin is an adipocyte-derived hormone. exogenous leptin allows the recovery of the reproductive function. in humans, leptin correlates positively with the body mass index (bmi). the aim of this study was to investigate the association of leptin with the toxic effects of iron overload. methods: 219 major beta thalassemic patients (119 men, 100 women) and 137 non thalassemic indivi...

Background: Hypoandrogenicity is common in obesity and in chronic inflammatory diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Adrenal androgens such as androstenedione (ASD) and dehydroepiandrosterone (DHEA) sulphate are low, which partly depends on the influence of TNF in chronic inflammatory diseases. Leptin is stimulated by TNF and is associated with hypoa...
