Leptin is a recently found hormone regulating body weight. In human obesity, this weight-regulating hormone level is in a positive correlation with FMI (fat mass index) and BMI (body mass index). In this study, we aimed to investigate the relation between serum leptin levels and BMI, PF (percentage fat), LMI (lean mass ındex), FMI and some other parameters of patients with haematologic malignant diseases. Fourty-four patients with haematologic malignant diseases and 25 healthy control group were taken into the study. In the comparison, there were no significant difference between the PF and FMI values of both groups, while the mean BMI and LMI values of the control group were significantly higher than that of the patient group. There was a positive correlation between leptin levels and BMI and FMI among parameters studied in our control group, whereas we couldn’t demostrate any such correlation in patient group. We estimate that the alteration may be due to disturbances in the feed back mechanism developing in patient with haematologic malignancy.
