“…The varying rate of prevalence, ranging from 5 to 60 %, of H. pylori infection has been documented by several authors [ 19 – 23 ]. In this study, we documented the prevalence of 16 % which is in accordance with the reported results of 14.2 % by Portorreal et al from Brazil [ 24 ] and 23.6 % by Ceylan et al from Turkey [ 25 ]. As much as 42.7 % of colonization rate was reported by Rafeey et al from Iran [ 26 ].…”

BackgroundHelicobacter pylori, a gram-negative bacterium, can cause gastritis, peptic and duodenal ulcers. It is considered an important public health problem for both developed and developing world. This bacterium is classified as the class 1 carcinogen because it can cause cancer.MethodsA hospital based study was conducted at Chitwan Medical College Teaching Hospital (CMCTH) from May to October 2014. Stool samples were collected from the suspected patients and were subjected to detection of the H. pylori stool antigen (HpSAg) following the procedures recommended by the manufacturer. A standard questionnaire on the potential risk factors was also designed and completed.ResultHpSAg was detected in 16 % of suspected patients. The children up to 10 years of age were found to be highly infected (36 %). The patients living in urban area were found more susceptible to develop H. pylori infection (P < 0.05). Tea drinking and repeated eating habit (more than twice a day) were listed as the important factors that can limit the H. pylori infections significantly (P < 0.05).ConclusionIn this hospital based study, a significant rate of prevalence was evaluated. However, we recommend a community based extensive study to reveal the real scenario of H. pylori infection in Nepalese populations.
