Obesity and adiponectin after kidney transplantation.
Obesity and hyperlipidaemia are found very frequently after kidney transplantation (Tx) and may represent independent risk factors for development of atherosclerosis and chronic allograft nephropathy. In a prospective metabolic study, we monitored, a total of 68 obese transplant patients [body mass index (BMI) > 30 kg/m2] with dyslipidaemia over a period of 24 months. We compared the findings of a new therapeutic regimen 1 year (start of the study) and 2 years after renal transplantation. Based on a Subjective Global Assessment Scoring Sheet, we started at the end of the first year with an individualized hypoenergic-hypolipidaemic diet (IHHD). Subsequently, after corticoid withdrawal, IHHD was supplemented regularly with statins (atorvastatin 10-20 mg/day)) and followed-up for 2 years. All patients were on a regimen of cyclosporin A or tacrolimus and mycophenolate mofetil. During the study period, there was a significant decrease in BMI (p < 0.025) and an increase of the adiponectin level (p < 0.01). Long-term therapy was associated with a significant decrease in serum leptin (p < 0.01) and lipid metabolism parameters (p < 0.01). Inulin clearance, mean systolic and diastolic blood pressure, proteinuria, lipoprotein(a) and apo-lipoprotein E isoforms did not differ significantly. Based on our results, we assume that obesity and hyperlipidaemia after renal transplantation can be treated effectively by modified immunosuppression (corticosteroid withdrawal), statins and long-term diet (IHHD). The increased level of adiponectin may be a marker of reducing atherosclerotic and chronic allograft nephropathy processes.
