  Purpose

The main objective of the study is to investigate the impact of H. pylori infection on immune activation and clinical outcome in HIV patients.

Other specific study objectives are:

  1. To investigate the effects of H. pylori infection on immune activation and the T-cell profile in HIV positive patients and compare those with HIV negative controls.
  2. To assess the influence of H. pylori infection on virological and immune parameters, and on clinical progression of HIV infection (WHO stage, opportunistic infections).
  3. To assess the prevalence of H. pylori infection among HIV patients in the Komfo Anokye Teaching Hospital.
  4. To assess the prevalence of gastrointestinal symptoms in HIV patients in Kumasi.
  5. To assess the association of H. pylori infection with gastrointestinal symptoms and pathology in HIV patients.
  6. To compare the clinical and immunological response to antiretroviral therapy and in HIV-patients with and without concomitant H. pylori infection.

Primary Outcome Measures:
  • T-cell status [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Frequency and activation status of T-cell subsets in HIV positive patients with versus without H. pylori infection


Secondary Outcome Measures:
  • CD4 response and virological status [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Change of CD4 cells and HIV viral load in HIV positive patients with versus without H. pylori infection during follow-up


Other Outcome Measures:
  • Clinical events [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Incidence of clinical events in HIV positive patients with versus without H. pylori infection during follow-up

  • Prevalence of H. pylori in HIV patients in Kumasi [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Prevalence of infection with helminth and other gastrointestinal parasites in HIV patients in Kumasi [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Prevalence and risk factors for gastrointestinal infections in HIV patients in Kumasi [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Association of gastrointestinal infections with abdominal pain, nausea, diarrhoea, anorexia [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    assessed by a questionnaire

  • Association of gastrointestinal infections with Body Mass Index and Hemoglobin level in HIV patients [ Time Frame: 12 months ] [ Designated as safety issue: No ]
