[Digestive involvement in AIDS].

The high frequency of gastrointestinal manifestations in AIDS raises new diagnostic and therapeutic problems. In this review paper the authors discuss the various clinical presentations and the different types of macroscopic or histological lesions, as well as the diagnostic approaches. This is followed by a description of the infectious agents responsible for opportunistic or non-opportunistic infections in AIDS patients. The epidemiological, clinical and therapeutic aspects of each species are reported.
