The association of serum leptin with biochemical parameters of bone turnover in maintenance hemodialysis patients
Journal Title: Αρχεία Ελληνικής Ιατρικής - Year 2006, Vol 23, Issue 5
Abstract
OBJECTIVE Leptin is a small peptide hormone that is mainly, but not exclusively, produced in adipose tissue and cleared principally by the kidney. Serum leptin concentrations and bone mass are directly related. This cross-sectional study was conducted on patients with end-stage renal disease (ESRD), who were undergoing maintenance hemodialysis (HD). METHOD Serum calcium, phosphorus, predialysis serum creatinine, blood urea nitrogen, alkaline phosphatase (ALP), intact serum PTH (iPTH) and serum leptin were measured in 36 dialysis patients, 10 of whom were diabetic. RESULTS A significant difference in serum leptin between male and female diabetic patients was seen with higher values in females. In all patients a significant positive correlation of the logarithm of serum leptin with the logarithm of serum iPTH and a significant positive correlation of serum leptin with body mass index (BMI) were found. In male HD patients a near significant and inverse correlation of serum ALP with serum leptin was seen. In female HD patients a near significant inverse correlation of serum leptin with serum phosphorus and a significant inverse correlation of serum leptin with Ca΄P products were found.
