Four children on chemotherapy for acute lymphoblastic leukemia presented with severe diarrhea and dehydration. Cryptosporidium was identified in the stools using modified ZiehlNeelsen stain. Two of them received paromomycin and responded well. One was started on paromomycin for 10 days and although there was clinical improvement, his stools examination continued to be positive for Cryptosporidium. He then received azithromycin for 10 days. He responded well and his stools became negative for Cryptosporidium. The fourth patient received azithromycin from the start and responded well. Cryptosporidium should be considered in all immunocompromised children with severe or prolonged diarrhea, and since it is not seen in a routine ova and parasite examination, the laboratory should be notified for diagnostic confirmation using modified ZiehlNeelsen stain. Immunocompromised children with Cryptosporidium diarrhea may benefit from paromomycin or azithromycin therapy.
