Background:In chronic renal failure leptin levels are elevated and BMD decreased, however, so far data about correlations between leptin and BMD in dialyzed patients are scarce. It has been suggested that leptin is a predictor of BMD in postmenopausal women. We examined the relationships between leptinemia, BMD and bone metabolism in HD and CAPD patients. We also assessed whether leptin is significant and independent predictor of BMD in dialyzed patients.Material/Methods: BMD was measured using dual energy X-ray absorptiometry (DEXA) at lumbar spine and femoral neck in 25 HD and 23 CAPD patients. Markers of bone turnover and leptin were studied using commercially available kits.Results: In femoral neck BMD was significantly higher in CAPD patients, without significant differences in BMD in lumbar spine.There was a negative correlation between BMD at the femoral neck and time on hemodialysis (r=–0.45,p
