Adenovirus infections in pediatric small bowel transplant recipients.

Journal Article

BACKGROUND: Adenovirus is commonly isolated from pediatric small bowel transplant recipients, but its clinical consequences remain poorly understood. METHODS: The medical records of pediatric small bowel transplant recipients transplanted between January 2003 and December 2007 were reviewed. Thymoglobulin and basiliximab induction and tacrolimus-based immunosuppression were the standard of care. Logistic regression analysis was performed to determine risk factors for infection, descriptive analysis to determine adenovirus incidence, and Kaplan-Meier curve analysis to determine the timing of events after transplantation. RESULTS: Ninety-eight patients were included; 38 were positive for adenovirus (incidence 23.5%), 23 for viral shedding, 23 for infections. Nine infections developed in the first month after transplantation and 8 during the following 5 months. The small bowel was involved in 19 cases. Younger age at transplantation was a risk factor for adenovirus infection (odds ratio=0.81, 95% confidence interval, 0.663-0.994, P=0.04). Treatment of rejection did not increase the risk of adenovirus infection. Cytomegalovirus D+/R- sero-status was a protective factor (odds ratio=0.26, 95% confidence interval, 0.06-1.089, P=0.04). CONCLUSIONS: Adenovirus infections affected 24% of recipients and developed mostly during the first 6 months after transplantation. Small bowel is the most frequently involved site. Younger age at transplantation is a risk factor for adenovirus infection; whereas cytomegalovirus D+/R- sero-status seems to be protective.
