Abstract

      Background and Objective: BabA2 and Hpa genes are involved in adherence of Helicobacter pylori (H.pylori) to gastric mucosal tissue. This study aimed to investigate the frequency of these genes in isolates of H. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer.

      Methods: Gastric biopsy samples were obtained from patients with gastritis, peptic ulcer and gastric cancer. A sample was sent to the laboratory for urease test and histopathology study, and another sample for DNA extraction. The frequency of BabA2 and Hpa genes was investigated using their specific primers by PCR.

      Results: Among the 80 analyzed biopsy samples, 51 (63%) were BabA2 positive, and the frequency of this gene in the samples of gastric cancer, gastritis and peptic ulcer was 61.1, 58.3 and 73.3%, respectively. In addition, 57 samples (71%) were Hpa positive, and the frequency of this gene in the samples of gastric cancer, gastritis and peptic ulcer was 55.5, 69.4 and 84.6%, respectively. There was no significant correlation between the presence of these genes and the type of H.pylori-related diseases.

       Conclusion: Frequency of BabA2 and Hpa genes is higher in the samples of peptic ulcer but there was no significant relationship between these genes and H.pylori-related diseases.

      Keywords: BabA2, Hpa, Gastric Cancer, Gastritis, Peptic Ulcer.

Abstract
Background: Intestinal infections with Helicobacter pylori mainly occur during childhood. If contracted, these infections may cause chronic gastritis, frequently leading to peptic ulcer disease in later life. This study aims to detect the prevalence of H. pylori infections in patients with active gastritis.
Methods: The study included 150 participants who were consuming daily anti-gastritis drugs to reduce the gas and were considered active gastritis patients and were recruited from Lekhnath 12, now known as Pokhara metropolitan-30, from May 2018 to March 2019. They were screened for H. pylori antibodies for detection of infection by the immunochromatographic rapid detection kit, and the data were analyzed using SPSS 2016.
Results: Serum anti-Helicobacter pylori antibodies were used to detect the presence of Helicobacter pylori in these participants. Among the 150 participants, 54 were males (36%) and 96 were females (64%). The results showed that 47 (31.3%) of the patients were positive for anti-Helicobacter pylori test. The age group 30 to 40 had the highest prevalence of 21 (14.0%). Using public water showed the highest prevalence with a P value of 0.04.
Conclusion: There should be an additional aspect required for the diagnosis and treatment of gastritis, which is the healthcare providers' and patients' awareness of the cause and most efficient treatments for this medical condition. Using only anti-gastritis drugs is not sufficient; treatment against Helicobacter pylori requires the right pathway of treatment by the use of several antibiotics.
