Abstract :
Objective: Serum leptin levels of chronic kidney disease patients have been detected higher than normal
population. The aim of this study was to investigate the effects of serum leptin levels on thrombocyte
aggregation in peritoneal dialysis patients.
Methods: Fourty three peritoneal dialysis patients were included in the study. Thrombocyte aggregation
was calculated from the whole blood subsequently the effects of different concentrations of human
recombinant leptin on thrombocyte aggregations were investigated. Four test cells were used for this
process. While leptin was not added into the first test cell, increasing amounts of leptin was added into
the second, third and fourth test cells to attain the concentrations of 25, 50 and 100 ng/ml respectively.
Results: Thrombocyte aggregation was inhibited by recombinant leptin in peritoneal dialysis patients.
Thrombocyte aggregation mean values were found statistically significantly higher in first test cell when
compared to leptin groups in peritoneal dialysis patients. For leptin groups we could not find any statistically
significant differences for thrombocyte aggregation mean values between any of the groups.
Conclusion: Further studies with larger number of peritoneal dialysis patients are required to prove the
action of leptin on thrombocyte aggregation.
