Influence of age in renal transplant infections: cases and controls study

Abstract

Kidney transplantation in elderly patients is a good therapeutic option, but the incidence of infections compared to younger patients must be studied. Case and control study was performed with 40 cases (patients older than 65) and 40 controls (younger than 65) receiving a kidney transplant between January 2000 and August 2002. In 32 cases (80%) and in 14 controls (32%), some type of infection appeared during the follow-up (odds ratio [OR] 5; 95% CI 1.6-20). The percentage of patients with bacterial infections was higher in the cases (70% vs. 28%; OR 5.7; 95% CI 1.9-20), especially for urinary infections. No differences for viral and fungal infections were observed in the two groups. Mortality rate was 13% in the cases (5% due to infections), whereas there was no controls' mortality. Although the number of bacterial infections was higher, kidney transplantation in elderly patients is a secure procedure.
