    Abstract:
    AIM: Excessive weight gain that leads to obesity is quite common after kidney transplantation. This is often attributed to immunosuppression. The aim of this retrospective study was to assess the effect of calcineurin inhibitors on post-transplant weight gain. METHODS: A total of 99 patients were studied. The patients were divided into cyclosporine A (CyA) and tacrolimus (Tac) groups and were evaluated for weight changes and risk factors related to weight gain. RESULTS: The weights of patients in both groups significantly increased after the sixth month. The median weight gain at 12 months was 3.5 and 8.0 kg compared with pretransplant dry weight in the Tac and CyA groups, respectively. The increases in the CyA group were significant compared with those of the Tac group. The prevalences of obese and overweight patients in both groups did not differ during a 12-month follow-up. The frequencies of diabetes mellitus, hypertension and dyslipidemia were comparable in both groups. The decrease in systolic blood pressure (BP) of the Tac group was significant compared with the decrease in the CyA group at the 12th month. In the 12-month follow-up period, the increases in triglyceride, total- and low-density lipoprotein-cholesterol values of the CyA group were significantly higher than those of the Tac group. The weight change between 0 and 12 months was negatively correlated with pretransplant body mass index (BMI) and positively with cumulative corticosteroid doses, total-cholesterol and BP changes. CONCLUSION: Only pretransplant BMI, creatinine clearance, CyA usage, being hypertensive and dyslipidemic were independent predictors of weight gain at the 12th month. Our results suggested that the type of immunosuppression may affect post-transplant weight gain.
