Abstract:
urpose:Adipocyte specific hormone, leptin is thought to regulate appetite and body weight, and serum level of leptin correlate with body fat content not only in adulthood but also in childhood. Adults who received cranial irradiation for childhood acute lymphoblastic leukemia are prone to hypothalamic damage in the form of growth hormone deficiency and leptin insensitivity. The purpose of this study is to evaluate the effect of total body irradiation on serum leptin concentration at short- term follow-up. METHODS:Twenty-four acute leukemia patients undergoing bone marrow transplantation(BMT) were enrolled in this study. They were divided into total body irradiation(TBI) group(n=13) and non total body irradiation(NTBI) group(n=11). Body mass index and leptin concentration at 1 week before BMT and 1 day, 1 week and 4 weeks after BMT were checked. Serum leptin concentration was measured by RIA method. RESULTS:Leptin concentration was well correlated with BMI(r=0.689, P<0.05). BMI were 17.96+/-2.48, 17.58+/-2.39, 17.39+/-2.30, 17.74+/-2.31 in TBI group and 16.91+/-1.88, 16.53+/-1.91, 16.50+/-1.96, 16.78+/-1.82 in NTBI group at 1 week before BMT and 1 day, 1 week and 4 weeks after BMT. Lepin concentrations were 4.31+/-3.57ng/ml, 3.22+/-2.87ng/ml, 3.78+/-4.41ng/ml, 3.46+/-2.96ng/ml in TBI group and 3.46+/-1.84ng/ml, 2.60+/-1.11ng/ml, 2.71+/-1.61ng/ml, 3.61+/-3.27ng/ml in NTBI group at 1 week before BMT and 1 day, 1 week and 4 weeks after BMT. BMI was different at each time period(P<0.05) but not different between two groups. Lepin concentration was not different between two groups and at each time period. CONCLUSION: Serum leptin concentration was not changed, but BMI was significantly decreased by total body irradiation at short-term follow-up.
