Abstract
IntroductionWeight gain after renal transplantation has a multifactorial etiology, which can be associated with complications such as hypertension, dyslipidemia and diabetes, with a probable impact on cardiovascular morbidity and mortality post-transplantation. ObjectiveThe objectives of this study were to investigate the prevalence of weight gain and obesity post-transplantation among renal recipients of a hospital and to evaluate the impact of immunosuppressive therapy without steroids. Materials and MethodsWe have evaluated all patients who had kidney transplantations performed between January 2005 and December 2009 at General Hospital of Fortaleza, who were older than 18 years of age and had at least 12 months of follow-up post-transplantation. Overweight was defined as body mass index (BMI) between 25 and 30 kg/m2 and obesity >30 kg/m2. The association between weight gain and the following variables was investigated: age and gender of the recipient and the donor, donor type, steroid use, presence of systemic arterial hypertension (SAH) and diabetes mellitus, creatinine, glucose, cholesterol, and triglycerides. ResultsThe study population included 203 recipients; 59.5% were males, their mean age systemic arterial hypertension (SAH) was 37 years, and 64.2% had deceased donors. In regard to immunosuppression, 41.3% made use of steroids. After 36 months of follow-up, the average weight gain was 6.6 kg in relation to the first month post-transplantation. Among the variables studied, the recipient's younger age and female gender, the younger donor, and the creatinine level were associated with greater weight gain after 36 months of transplantation. ConclusionThe percentage of weight gain was on average 9% after 36 months post-transplantation, although the prevalence of overweight and obesity increased significantly in the same period. The use of steroid therapy had no impact on the percentage of weight gain post-transplantation, and association was observed only between the younger age and the female gender of the recipient, the younger donor age, and the creatinine level with the highest weight gain post-transplantation.
