Helicobacter pylori Infection and Association with Anaemia in Cameroon Patients, Using GastroPanel® Serological Biomarkers (Pepsinogen I; Pepsinogen II; Gastrin-17; Helicobacter pylori IgG)

Abstract

Introduction: Helicobacter pylori (H. pylori) together with chronic atrophic gastritis have also been associated to extragastric manifestations including neurological, dermatological, ocular, cardiovascular, metabolic, allergic diseases and hematologic disorders. Several studies have associatedH. pylori with anaemia, iron deficiency and iron deficiency anemia. Little or no data on the association of H. pylori infection andanaemia exist in Cameroon. We therefore evaluated the prevalence H. pylori infection among patients with anaemia. Methodology: Blood samples were aseptically collected for the measurements Helicobacter pylori IgG antibodies, pepsinogene I et II levels, gastrine-17 in a total of 150 patients during the period February to July 2020. The blood samples required for the study were collected prospectively. Ethical clairance was obtained from the Centre Regional Ethics Committee for Human Sciences. An authorization of research was obtained from the authorities of General Hospital of Yaounde. All participants signed an informed consent form. Results: The GastroPanel® results showed that the prevalence of H. pyloriinfection was 90(60.00%).We observeda strong association of H. pylori with anaemia (OR 2.19, 95% CI 1.08–4.46; p=0,02). Conclusion: The prevalence of H. pylori infection is high in patients with anaemia and thus requires continuous monitoring of these patients.
