H. pylori infections and chronic kidney diseases are in increasing, global records; if not well controlled in a specific population, these diseases might lead to more clinical complications.Methods: In this retrospective study, we investigated the prevalence of acute H. pylori infections among 127 dialysis patients via subjecting their serums to the enzyme-linked immunosorbent assay (ELISA) to detect the human Immunoglobulin M (IgM) against H. pylori infections. Samples were from dialysis patients in a single hemodialysis center in Medina, Saudi Arabia, from January to August 2021.Results: Our results indicated the significant prevalence of H. pylori acute infections among 33.1% of renal failure patients recruited in this study, chi-squared: 14.559, p-value: 0.0001. In addition, no significant occurrence of acute H. pylori infection among males and females, chi-squared: 1.823, p-value: 0.177. Furthermore, the prevalence of acute H. pylori infection was not significant in different age groups of renal failure patients. Chi-squared: 6.803, p-value: 0.147, despite H. pylori-infected cases predominantly represented in patients above 51 years. Moreover, we noticed that hypertension, followed by diabetes, was the most prevalent underlying medical condition among acute infected H. pylori and renal failure patients.Conclusion: We documented the significant prevalence of acute H. pylori infection among renal failure patients. We also highlighted and discussed the possible potential roles of H. pylori in renal failure and other chronic diseases. Routine screening and treatment for acute H. pylori infection for chronic kidney diseases, hypertension, and diabetes patients would positively reduce the bacterium’s progressive effects on them. They might even improve the control of these diseases.Keywords: Helicobacter pylori, acute infection, chronic kidney disease, renal failure, hypertension, diabetes mellitus

Coinfections with respiratory viruses among SARS CoV-2 patients have been reported by several studies during the current COVID-19 pandemic. Most of these studies designated these coinfections as being hospital-acquired infections; however, there is inadequate knowledge about community-acquired respiratory coinfections among SARS CoV-2 patients.In this retrospective cohort study, we investigated the seroprevalence of influenza A, influenza B, and parainfluenza-2 among newly hospitalized patients with confirmed COVID-19 infections (n = 163). The study was conducted during the early phase of the COVID-19 pandemic in Saudi Arabia (from April to October 2020). The patients' serum samples were subjected to commercial immunoglobulin M (IgM) antibody tests against the three aforementioned viruses.Seropositivity for influenza A and B and parainfluenza-2 occurred only in 4.2% (7/163) of COVID-19 patients, indicating simultaneous acute infections of these three viruses with SARS CoV-2 infection. All coinfection cases were mild and misdiagnosed during the care period in the hospital.This study highlights the low prevalence of community-acquired respiratory infections among COVID-19 patients in the current pandemic and we discussed the possible factors for this finding. During newly emerging epidemics or pandemics, considering other respiratory viruses circulating in the community is essential to avoid their misdiagnosis and account for their possible negative effects on pandemic disease management and prognosis.
