Core Tip

Core tip: Diarrhea caused by Cryptosporidium is a serious and underrecognized cause of diarrhea in solid organ transplant recipients. The most important diagnostic challenge is low index of suspicion, since many new diagnostic methods have improved detection of the parasite. Treatment can be challenging as the disease may cause severe dehydration and antiparasitic drugs have modest activity. Electrolyte and fluid replacement, reduction of immunosuppression and antiparasitic therapy are the cornerstones of management. Newer antiparasitic drugs and vaccines may help manage the disease in the future.
