    Abstract:
    INTRODUCTION: The impact of obesity, a frequent problem after renal transplantation, which has been associated with poor graft and patient survival, was evaluated on renal function and cyclosporine (CsA) blood levels. PATIENTS: We retrospectively evaluated the data of adolescent renal recipients between 1994 and 2004. Patients with serum creatinine > or = 2.5 mg/dL were excluded. We grouped the data with regard to the body mass index (BMI) percentiles as group I (BMI > 95th), group II (BMI < 95th), group III (BMI > 85th), group IV (BMI < 85th). We compared the clinical and laboratory findings between groups I and II and between groups III and IV. RESULTS: We evaluated 778 visits of 27 patients (M/F: 19/8). There were 30 visits in the obesity period (group I) and 72 visits after the overweight periods were added (group III). Serum creatinine levels were significantly higher and glomerular filtration rate levels significantly lower among obese and/or overweight than lean periods (P < .05). Proteinuria levels were similar in groups I and II, but significantly higher in group III than group IV (P = .356 and .000, respectively). CsA(mg/bw), CsA(mg/bmi), and CsA(mg/bsa) levels were significantly lower in group I than group II and in group III than group IV (P < .05), while C0 and C2 levels were similar (P > .05). CONCLUSION: Weight gain is associated with worse renal functions but not greater proteinuria in our patients. Smaller CsA doses were sufficient to maintain C0 and C2 levels similar to the lean patients, results that were parallel to those of adult renal recipients.
