Study of Prevalence of Gastritis Caused by H. pylori and Correlation of Urease Test with Serology (ELISA) Test

Abstract

ABSTRACT Introduction: H. pylori are a pathogen of global importance. Gram-negative curved flagellate bacilli are implicated as one of the most trivial complaints of and are associated with peptic ulcer disease gastritis ulcer and gastric malignancy. This study was performed to find out the prevalence of Helicobacter pylori (H. pylori) infection in patients presenting the symptoms related with gastritis with or without chemically known peptic ulcer. Materials and Methods: The study was undertaken with the help of the Christensen and quotes urease test on endoscopic biopsy specimen and correlated with the detection of immunoglobulin IgG in the serum against H. pylori by an ELISA technique. Results: A total of 67 cases were analyzed in which 29 (43%) cases were positive for H. pylori. The endoscopic findings of acid peptic diseases show 21 (31.4%) cases of stomach ulcer, and 3 (4.5%) have esophagitis, whereas 43 (64.1%) have nonulcer dyspepsia. There is strong positive association between the urease tesr and ELISA test. Conclusion: The urease test is a quick and inexpensive test with high specificity and sensitivity, but since it is an invasive test, it has reduced patient compliance.
