HIV and diarrhea in the era of HAART: 1998 New York State hospitalizations

Abstract

Background: This study reflects an attempt to identify the causes of diarrheal illness in hospitalized HIV patients in light of therapeutic advancements in HIV management.

Methods: The study identifies the various etiologies associated with diarrhea among HIV patients hospitalized in New York State in 1998. Data for this study were extracted from the New York State Department of Health Statewide Planning and Research Cooperative System. Pathogens recognized to cause diarrhea in persons with HIV and general codes identifying diarrhea were examined by using the principal and all secondary diagnoses based on the International Classification of Diseases 9th Revision Clinical Modification codes.

Results: Based on the Statewide Planning and Research Cooperative System data set, more than 15,000 patients with HIV were hospitalized in 1998. Among the HIV patients hospitalized, 2.8% were admitted with a diarrheal diagnosis. The following diagnoses occurred the most frequently among HIV patients hospitalized with a diarrheal illness: Clostridium difficile (51.3%), other protozoal diseases (18.1%), and other organisms, not elsewhere specified (11.7%).

Conclusions: In the era of highly active antiretroviral therapy, diarrhea is still an occurring symptom in HIV patients. Despite the relatively small percentage of hospitalizations attributed to diarrhea, clinicians must remember that even "mild" to "moderate" diarrhea can have a debilitating impact among persons with the symptom.
