title: [Influence of weight gain during the first year after kidney transplantation in the survival of grafts and patients].
abstract: BACKGROUND
  After receiving a kidney allograft, patients tend to gain weight acquiring the risk associated with overweight and obesity.
  
  
  OBJECTIVE
  To compare the evolution during 10 years after transplantation of patients who gained more than 15% of their initial weight during the first year after receiving the graft with those who did not experience this increase.
  
  
  METHODS
  Cohort study of 182 patients transplanted in a single hospital between 1981 and 2003. Demographic data, weight gain during the first year, drugs used, complications and evolution of patients and grafts were recorded.
  
  
  RESULTS
  Seventy two patients gained more than 15% of their weight during the first year. These were discharged after receiving the graft with a lower serum creatinine than their counterparts (1.46 ± 0.71 and 1.97 ± 1.74 mg/dl respectively, p = 0.02). Ten years mortality with a functioning kidney was higher among weight gainers (25 and 12.7% respectively, p = 0.03). No other differences were observed between groups.
  
  
  CONCLUSIONS
  Patients who gained more than 15% of their initial weight during the first year after receiving a kidney graft have a higher 10 years mortality with a functioning kidney.
