Association of Serum Leptin with Various Biochemical Parameters of Bone Turnover in Maintenance Hemodialysis Patients

Hamid Nasri M.D.
Leptin is a small peptide hormone that is mainly but not exclusively, produced in adipose tissue. leptin is 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. Serum calcium, phosphorus, predialysis serum creatinine, blood urea nitrogen and also alkaline phosphatase (ALP) and also intact serum PTH (iPTH) and serum Leptin were measured too. In this study a significant difference of serum leptin between males and females of diabetic patients with more values in females was seen. In all patients a significant positive correlation of logarithm of serum leptin with logarithm of serum iPTH and a significant positive correlation of serum leptin and BMI in were found. In male hemodialysis patients a near significant and inverse correlation of serum ALP with serum leptin was seen, moreover in female hemodialysis patients a near significant inverse correlation of serum leptin with serum phosphorus and also a significant inverse correlation of serum leptin with CaXP products were found too. In hemodialysis patients serum leptin affects bone activity and need further investigation this aspect of hemodialysis patients.
