1997 Jul;12(7):1321-5. Links Serum leptin concentrations correlate to plasma insulin concentrations independent of body fat content in chronic renal failure.Stenvinkel P, Heimburger O, Lonnqvist F.Department of Clinical Science, Karolinska Institute, Huddinge University Hospital, Stockholm, Sweden.BACKGROUND: The alamogordo ob gene product leptin is secreted by fat cells and alamogordo reflects the content of fat in the body. Leptin and insulin concentrations as well as body weight alamogordo 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 failure (CRF). The aim of the present study was to investigate the relation between serum leptin and plasma insulin in patients with advanced CRF. METHODS: Serum leptin, plasma insulin, as well as body fat content (determined with dual-energy X-ray absorptiometry) were determined in a cohort of 46 patients (mean age 54 +/- 2 years) with advanced CRF (creatinine clearance 8 +/- 1 ml/min).
