Abstract
In contrast to the esophagus and colon, the stomach is a less common site for the occurrence of primary opportunistic infections in AIDS. Most gastric opportunistic infections in AIDS occur as part of a generalized gastrointestinal or systemic syndrome (ie, secondary involvement). Besides infections, opportunistic neoplasms such as Kaposi's sarcoma and non-Hodgkin's lymphoma can also involve the stomach in AIDS patients. Since the introduction of highly active antiretroviral therapy, the incidence of gastrointestinal disorders has decreased in HIV-infected patients and the incidence of nonopportunistic gastrointestinal disorders, including Helicobacter pylori infection and peptic ulcer disease, has risen. The main diagnostic tool for AIDS patients with suspected gastric pathology is upper endoscopy with biopsies. The article presents the various gastric pathologies that can occur in AIDS and focuses on their clinical and endoscopic approach.
