Background Patients with cancer who receive intensive chemotherapeutic regimens are subject to profound immunosuppression and are susceptible to an extended array of pathogens. Procedure The infectious causes of symptomatic gastroenteritis as evidenced by diarrhea +/− fever, vomiting, and abdominal colic in children following chemotherapy were prospectively monitored at National Cancer Institute, Cairo University. Results A total of 104 diarrhea episodes were recorded in our institution during a 10‐month period, of which an infectious cause was detected in 74 (71.1%). Bacterial and fungal pathogens were isolated in culture from 41 (39.4%) and 24 (23.1%), respectively, while Clostridia difficile (C. difficile) and Cryptosporidium parvum (C. parvum) were detected in 15 (14.4%) and 10 (9.6%) of 104 diarrhea episodes following chemotherapy, respectively. Mixed infections were found in 24 of the patients; whereas, no cause was demonstrable in 30. Hospital acquired and mixed infections were the worst as regards morbidity ( P = 0.004 and 0.02) and mortality ( P = 0.007 and <0.001) of the infectious episode regardless the cause, respectively. On multivariate analysis, C. difficile was associated with the highest mortality rate (OR = 0.04, 95% CI = 0.01–0.19), followed by fungal pathogens (OR = 0.20, 95% CI = 0.05–0.74) and bacterial infections (OR = 0.20, 95% CI = 0.05–0.79). Conclusions Infectious gastroenteritis is an important cause of morbidity and mortality in hospitalized pediatric cancer patients receiving intensified protocols of chemotherapy. © 2003 Wiley‐Liss, Inc.
