1. The obese gene product leptin, secreted exclusively from adipocytes, was discovered to serve as a satiety factor and to play an important role in regulating body weight. In adults, the serum leptin level reportedly increases with the degree of obesity. Leptin receptors are expressed in various tissues, and recent in vitro studies suggest a role for leptin in haematopoiesis. 2. The present st...

Carlson, G. L., M. Saeed, R. A. Little, and M. H. Irving. Serum leptin concentrations and their relation to metabolic abnormalities in human sepsis. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E658–E662, 1999.—Circulating leptin concentrations are raised in animal models of inflammation and sepsis. The purpose of this study was to determine the effect of sepsis on serum leptin concentration in...

BACKGROUND Some studies propose that changes in leptin concentrations (above or under the normal range) result in infertility. Therefore, we investigated serum and follicular fluid leptin concentrations in infertile women with polycystic ovary syndrome (PCOS). OBJECTIVE To study serum and follicular fluid leptin concentrations in infertile women with PCOS. MATERIALS AND METHODS We conducted...

Abstract Background Idiopathic intracranial hypertension (IIH) is typically seen in females of childbearing period; therefore, it possible that female sex hormones have a pathogenic role IIH. Obesity considered as strong risk factor for IIH, Leptin levels the serum and CSF were found to be positively correlated with anthropological measures obesity. The leptin pathogenesis idiopathic not fully ...

Introduction: Leptin, generated by the obesity gene, acts as an anti-obesity hormone that plays a key role in regulating weight. We aimed to investigate the effects of eight weeks of selected aerobic training on serum leptin levels, anthropometric indices and maximal oxygen consumption (VO2max) in obese men. Methods: Twenty healthy elderly men were selected by convenience sampling method and...

We have studied the effect of prolonged hyperinsulinemia and hyperglycemia on serum leptin levels in young nonobese males during 72-h euglycemic-hyperinsulinemic and hyperglycemic ( approximately 8.5 and 12.6 mM) clamps. Hyperinsulinemia increased serum leptin concentrations (by RIA) dose-dependently. An increase in serum insulin concentration of > 200 pM for > 24 h was needed to significantly ...

BACKGROUND Beta-thalassemia is the most common hematology disease in human and leptin is one of the hormone that produce by adiposities cells. The purpose of this study was to investigate the relationship between serum leptin level and thyroid hormones in children with major beta-thalassemia. MATERIALS AND METHODS This descriptive-cross sectional study was performed on 90 children aged 6-16 y...

OBJECTIVE Circulating leptin levels correlate positively with the degree of obesity and prolonged hyperinsulinaemia increases serum leptin levels. Moreover, insulin secreting beta-cells express functional leptin receptors indicating a functional relationship between leptin and insulin. The aim of this study was to examine the relationship between fasting serum leptin levels and measures of insu...

AIM This study was designed to clarify the role of leptin and adiponectin in preeclampsia (PE) pathogenesis and different subtypes of preeclampsia. METHOD This case control study was performed in 45 PE patients and 45 healthy controls matched for age, BMI, and ethnicity. Serum leptin and adiponectin levels were determined by enzyme linked immunosorbent assay (ELISA). RESULTS Maternal serum ...

AIMS We evaluated the links between leptin and visfatin levels and fertilization rates in nonoverweight (NOW) women with PCOS (NOW-PCOS) from Apulia undergoing in vitro fertilization/embryo transfer (IVF). MATERIALS AND METHODOLOGY We recruited 16 NOW women with PCOS (NOW-PCOS) and 10 normally ovulating NOW women (control-NOW). All women underwent IVF. Androgens, 17- β -estradiol (17 β -E2), ...
