EPIDEMIOLOGICAL STUDY OF GASTRODUODENAL DISEASES (HELICOBACTER PYLORI) IN THE REGION OF TIARET, ALGERIA

It was judicious to estimate the prevalence of infection by Helicobacter pylori, responsible for several gastroduodenal pathologies in the region of Tiaret, targeting a retrospective cohort of 1230 patients, presenting symptoms of gastroduodenal diseases, collected over a period of 6 years (2015-2020) at the hepato-gastroenterology department of EPH Youcef Damardji in Tiaret. After an analytical study, it turns out that our studied population has a considerably high prevalence rate of infection 69%, and this under the influence of three preponderant factors: sex (male), age (from 50 to 59 years old) and the region where the prevalence is considerably greater in the city of Tiaret than that recorded in rural areas. On the other hand, diseases associated with H. pylori such as ulcer, gastritis and gastric cancer have a great influence on this prevalence.
