Helicobacter pylori infection does not belong to the spectrum of opportunistic infections in people living with HIV (PLHIV). To evaluate the Helicobacter pylori infection prevalence rate trends in HIV co-infected individuals in comparison to the HIV-negative population, we compared histopathological findings of H . pylori positive gastritis (gastritis topography and histopathology) between 303 PLHIV and 2642 HIV-negative patients who underwent esophagogastroduodenoscopy (EGD) between 1993 and 2014 due to dyspeptic symptoms. The prevalence of H . pylori infection was significantly higher in HIV-negative controls than in PLHIV (50.2% vs. 28.1%). A significantly positive linear trend of H . pylori co-infection in PLHIV was revealed in the observed period (b = 0.030, SE = 0.011, p = 0.013), while this trend was significantly negative in HIV-negative patients (b = - 0.027, SE = 0.003, p < 0.001). Patients with HIV/ H . pylori co-infection had significantly higher CD4 + T cell counts and more often had undetectable HIV viremia, due to successful anti-retroviral therapy (ART). Stomach histopathological findings differed between HIV co-infected and H . pylori mono-infected patients. Our findings confirm that the ART has changed the progression of HIV infection, leading to a significant increase in the prevalence of H . pylori infection in dyspeptic PLHIV over time. Our data also suggests that a functional immune system may be needed for H . pylori -induced human gastric mucosa inflammation.
