Objective: The objective of this study was to identify the incidence of posttransplantation lymphoproliferative disease (PTLD) among children within 1 year after liver transplantation.
Methods: This retrospective review analyzed information in medical charts of pediatric (younger than 18 years of age) recipients of liver transplants between September 2000 and December 2007.
Results: Seventy-one patients underwent a liver transplantation and 7 (9.85%) developed PTLD. Among this group, 6 children were girls and 1 was a boy. The median age at transplantation was 35.14 months. Indications that led the children to have their transplantation were 1 case of hemangioendothelioma, 1 case of autoimmune hepatic cirrhosis, 1 case of alpha-1-antitrypsin deficiency, and 4 cases of biliary atresia. The most frequent symptoms were splenomegaly, diarrhea, and fever. The median time from the first symptoms to the initial treatment was 9.7 days. The standard treatment was withdrawal of immunosuppression and close observation of tacrolimus levels and liver function tests associated with antiviral drugs and chemotherapy. Four among 7 children died; 3 children recovered. All 3 children who recovered has presented at the transplantation center within 5 days of initiation of symptoms (P = .033896).
Conclusion: Despite its rarity, when it occurs, PTLD shows a high mortality rate. Therefore, it is necessary to have interdisciplinary work between the medical team that performs the transplantation and those promoting the primary care to diagnose the disease early and treat it effectively.
