RESUMO
We report a case of giant condyloma that developed in a pediatric heart transplant recipient. This infection progressed for several months despite reduction in immunosuppression, topical treatment, and oral cimetidine therapy. Complete resolution was observed following 7 months of topical cidofovir, without evidence of systemic toxicity or rejection.

Abstract:Background andObjectives: Immunosuppressed individuals are at particularly increased risk for human papilloma virus-related infections. The primary objective of our study is to determine if there are any adverse effects associated with high-dose cimetidine treatment. A secondary objective is to report our experience with cimetidine in the treatment of cutaneous warts in pediatric heart transplant recipients. Methods and Results: This was a retrospective observational study. A total of 8 pediatric heart transplant recipients diagnosed with multiple recalcitrant warts were the subject of the study. All patients were treated with cimetidine (30-40 mg/kg/day) in two divided doses for 3 to 6 month durations. All patients had complete resolution of their lesions except 1 patient who had no clinical improvement. Of these 8 patients, one had recurrence of warts at one year follow-up, which resolved with restarting cimetidine therapy. One patient who had only 3 months of cimetidine therapy had immediate relapse after cimetidine was stopped. None of them had significant change in their tacrolimus trough, serum creatinine, and alanine transaminase levels. No adverse events were reported except one patient experienced mild gynecomastia. Conclusion: Cimetidine can be a safe and alternative treatment option for multiple warts in pediatric heart transplant recipients.
