Determine the Prevalence of cagA and Baba of Helicobacter Pylori Isolated from Gastric Atrophic Patients

Abstract

Objective: The aim of this study is to determine the prevalence of cagA and babA of helicobacter pylori isolated from gastric atrophic patients. Study Design: Descriptive/Analytical Place and Duration: The study was conducted at Medicine/Gastroenterology department of Khyber Teaching Hospital and Peshawar Institute of Medical Sciences, Peshawar for six months duration from March 2020 to August 2020. Methods: Total one hundred and twenty patients of both genders were presented in this study. Patients were aged between 20-80 years of age. Patients detailed demographics age, sex and body mass index were recorded after taking informed written consent. All patients of gastroduodenal disorders were undergone for isolation of bacteria by using standard techniques. Complete data was analyzed by SPSS 22.0 version. Results: Total 50 (41.7%) patients were males and 70 (58.3%) patients were females. Mean age of the patients were 41.96 ± 16 years with mean BMI 25.24 ± 4.8 kg/m2. Frequency of H pylori was isolated in 30 (25%) patients in which 13 patients had atrophic gastritis, 9 patients had gastric ulcer and 8 patients had acute gastritis. Prevalence of cagA gene was 16 (53.33%) and babA was 10 (33.33%) in H. pylori isolated patients. Significantly difference with p value <0.05 was observed between cagA positive strains and patients of gastric atrophic. The involvement of gastric atrophic patients was not correlated to the babA gene. Conclusion: We concluded in this study that different cagA positive H. pylori can be retrieved from gastric atrophy patients. Keywords: Gastric atrophy, Gastric cancer, cagA, babA, Helicobacter pylori
