The Impact of Gut Microbiota on Gender-Specific Differences in COVID-19 Patients

Background: The gut microbiome has been shown to play a crucial role in modulating the immune system and protecting against infections. Studies have reported gender differences in the gut microbiome composition, but little is known about how these differences may be affected by COVID-19 infection. In this study, we aimed to compare the gut microbiome composition of male and female patients with COVID-19. Methods: We obtained gut microbiome data from the study by Zuo et al. (2020) available in the NCBI BioProject database under accession number PRJEB56080. We created two cohorts, one consisting of male patients and the other consisting of female patients. We used the SRA Toolkit to download the gut microbiome data and performed taxonomic classification and diversity analysis using the EZBioCloud server. Results: Our results showed that the gut microbiome composition of male and female patients with COVID-19 differed significantly in terms of alpha diversity indices, with male patients having higher species richness and diversity than female patients. However, no significant differences were observed in beta diversity indices between the two cohorts. Conclusion: Our findings suggest that sex may play a role in modulating the gut microbiome composition in COVID-19 patients. Future studies are needed to explore the underlying mechanisms behind this gender difference and its potential implications for COVID-19 pathogenesis and treatment.
