Abstract

Introduction

There are several diagnostic techniques for detecting , the most common of which are upper GI endoscopic biopsies and stool specimens as optimal samples. The goal of this study was to detect and compare infection using the following techniques: rapid urease test (RUT), polymerase chain reaction (PCR), culture, histopathology, and stool antigen test (SAT), as well as to assess their validity in detecting infection.

Methodology

Patients with dyspepsia who presented to the Department of Gastroenterology's Outpatient Department and In-Patient Department between September 2021 and December 2022 were screened (Rome IV criteria). Endoscopy was used to diagnose and recruit patients with Functional dyspepsia (FD) and Peptic ulcer disease (PUD). Each biopsy sample was subjected to a battery of microbiological testing. Patients were considered infected with if any three of five tests were found to be positive. The outcomes of all diagnostic modalities were documented and analysed.

Results and Discussion

A total of 171 patients were enrolled; the majority of them were male (62.60%), with a median age of 43 years. In 120 cases (70.18%), was identified. The RUT showed the following results: sensitivity, specificity, positive predictive value, negative predictive value, and accuracy: 91.67%, 74.51%, 89.43%, 79.17%, and 86.55%; PCR (ureC gene): 91.67%, 100%, 100%, 83.61%, and 94.15%; Histopathology: 61.67%, 100%, 100%, 52.58%, and 73.10%; and SAT: 87.50%, 94.12%, 97.22%, 76.19%, and 89.47%, respectively.

Conclusion

The present study sheds light on the various diagnostic modalities and their efficacy in detecting infection. Since several diagnostics are available for detecting infection, the question of which method to use arises. Thus, the sensitivity, specificity, availability, rapidity in obtaining results, and availability of the test, with added value such as detection of pathogenic qualities, must all be considered.
