Comparison of Helicobacter pylori in hospitalized COVID-19 patients with and without gastrointestinal symptoms

Background and aim: Helicobacter pylori plays an important role in causing digestive diseases. The purpose of this study is to investigate Helicobacter pylori in COVID-19 patients with and without gastrointestinal symptoms.

Methods: In this case-control study, all patients with COVID-19 admitted to Imam Khomeini Hospital in Jiroft city in 2021 were convenience sampled and divided into two homogeneous groups. Ninety-five patients with COVID-19, who presented with gastrointestinal symptoms, were included in the case group, while 95 patients with COVID-19 without gastrointestinal symptoms were included in the control group. Noninvasive diagnostic methods, including serology and stool antigen tests, were used to identify Helicobacter pylori in the studied patients.

Results: Fifty-three people (55.8%) from the case group had Helicobacter pylori, and 48 (50.5%) from the control group had Helicobacter pylori. Among the 53 people from the case group, 27 (50.9%) were men and 26 (49.1%) were women. Nineteen people (35.8%) were taking pantoprazole, 10 people (18.8%) were taking nonsteroidal anti-inflammatory drugs, 20 people (37.7%) were taking narcotics, and 7 people (13.2%) had peptic ulcer. Seven people (13.2%) had an H2 blocker, and 21 people had an underlying disease. A significant relationship between infection with Helicobacter pylori and the use of pantoprazole, nonsteroidal anti-inflammatory drugs, narcotics, peptic ulcer, underlying disease, and H2 blocker in COVID-19 patients with gastrointestinal symptoms and without gastrointestinal symptoms was present (P-value < 0.05).

Conclusion: The prevalence of Helicobacter pylori infection in patients with COVID-19, who have gastrointestinal symptoms, is high and should be considered as a treatment criterion for people infected with COVID-19.
