title: Effect of thymoglobulin in graft survival and function 1 year after kidney transplantation using deceased donors.
abstract: This study evaluated 1-year graft function and survival among kidney transplantations from deceased donors using thymoglobulin (Thymo) as an induction strategy.
  
  
  METHODS
  Fifty-seven percent of patients were men and overall mean age was 42 +/- 15 years. Cold ischemia time was 20.1 +/- 4.8 hours. The primary outcome was defined as survival not censored for death after 1 year. The secondary outcome was defined as a comparison of function and survival among patients who received more or less then six doses of Thymo.
  
  
  RESULTS
  Four patients experienced acute rejection episodes and the other three died during follow-up. One-year graft survival was 91% with a mean serum creatinine of 1.28 +/- 0.43 mg/dL. Cytomegalovirus infection occurred in 56%. Forty-two (64%) patients displayed acute tubular necrosis of mean duration of 6.89 +/- 7.48 days. Patients who received lower doses showed better serum creatinine values 3 months (1.45 vs 1.86 mg/dL, P = .013) and 12 months (1.05 vs 1.50 mg/dL, P = .04). The difference was probably due to acute tubular necrosis that produced a RR of 1.7 (P = .02; CI 1.04-2.97) when compared with patients with Scr values above 1.30 mg/dL. When censored for death, graft survival was not different between the two groups (< or =6 doses 93% vs >6 doses 97%, P = .43).
  
  
  CONCLUSIONS
  Immunologic induction with Thymo produced excellent graft survival after 1 year with preservation of graft function. Delayed graft function was the most important determinant of graft function after 1 year.
