Cryptosporidium is an intracellular protozoa that can cause gastroenteritis in humans. In immunocompromised hosts, infection can be severe, leading to life-threatening persistent diarrhea. There is limited experience in treating this infection in solid organ transplants. Although newer drugs active against Cryptosporidium exist, they are only licensed in the USA for treatment of immunocompetent hosts. Here we describe a seven-year-old renal transplant recipient with severe cryptosporidiosis. He had a protracted course of diarrhea of up to 2 L/day. He was successfully managed with combination antimicrobial therapy including nitazoxanide, paromomycin, and azithromycin. In conjunction with this regimen, he had a reduction in immunosuppression and complete bowel rest. His stool pattern normalized in four weeks and he has had no recurrence after six months of follow up.

We report on the effectiveness of intravenous ribavirin for severe adenoviral pneumonia in a 10-month-old male following orthotopic liver transplantation. On day 20 post-transplantation, he developed high fever, marked respiratory compromise, and hypoxemia. The chest radiograph showed bilateral pulmonary infiltrates. Samples of bronchoalveolar lavage fluid grew adenovirus, serotype 1. Marked clinical and radiological improvement was noted after intravenous ribavirin therapy. A prospective clinical trial is needed to determine the efficacy of ribavirin therapy for severe adenovirus disease. Pediatr Pulmonol. 2000; 29:69–73. © 2000 Wiley-Liss, Inc.
