Association of Helicobacter pylori Infection and Atrophic Gastritis with Chronic Renal Insufficiency in Yaounde Cameroon, Using Gastropanel® Serological Biomarker Panel (Pepsinogen I; Pepsinogen II; Gastrin-17; Helicobacter pylori Igg)

Introduction: Helicobacter pylori infection is associated with an atrophic gastritis peptic and duodenal ulcer and gastric cancer. Patients with chronic renal diseases usually have dyspeptic symptoms. Several investigations have demonstrated an association between H. pylori infection and chronic kidney disease, although their results are still conflicting. We therefore aimed, to clarify the prevalence of H. pylori infection in patients receiving dialysis.

Materials and Methods: Patients undergoing hemodialysis were recruited at the University Teaching Hospital of Yaounde, between January and May 2019. The clinical and socio-demographic information of the patients was recorded. 5 ml of blood were collected aseptically for Pepsinogen I and II enzymes, gastrin17 hormone and IgG anti H. pylori anti-body. The test parameters were analyzed using a GastroSoft software application. The data was analyzed using Epi Info 7.0. All statistics were 95% CI. Ethical clearance was also obtained from the National Ethics Committee. Authorization was obtained atthe University Teaching Hospital.

Results: A total of 60 subjects were recruited aged 25-74 years, (mean±SD 52.03 ± 12,78) years;22(45.16%) females, aged 29 to 71years(mean±SD 47,45 ± 11.46) years and 38(54.84%) males aged 25 to 74 (mean±SD 56,47±12.25) years. Female / male ratio was 1.2. Overall, 26(43.33%) subjects were positive for H. pylori infection (IgG≥30EIU). The prevalence of atrophic gastritis obtained was (23.33%)(PG1< 30µg/l). The mean H. pylori IgG antibodies were significantly higher in obese than non obese subjects (F=3.59; p=0,01). A significant increase in the mean creatinine(P=0.008), andurea (P=0,05) was observed in H. pylori positive than negative ones. Conclusion: H. pylori infection is highly prevalent amongst patients with chronic renal failure and may thus require continuous follow up.
