title: Helicobacter pylori infection in symptomatic HIV-seropositive and -seronegative patients: a case-control study.
abstract: We conducted a case-control study in a Greek hospital to evaluate the prevalence and morbidity of Helicobacter pylori in HIV-infected patients. HIV-seropositive patients were infected by H. pylori less often than HIV-seronegative controls [12/58 (20.7%) versus 38/58 (65.5%),p < 0.001]. The mean CD4 count was lower for H. pylori-negative than H. pylori-positive HIV-infected patients (p < 0.007). Also, among HIV patients, prior use of antibiotics or proton pump inhibitors was more common in those without H. pylori infection, however, this difference was not statistically significant (p = 0.06). The grading of the density of H. pylori infection and the grading of the histomorphological findings according to the Sydney classification were similar between HIV-seropositive and -seronegative patients with H. pylori infection.
