ARTICLE HIGHLIGHTS
Research background

An important area of effective control of the coronavirus disease 2019 (COVID-19) pandemic is the study of the pathogenic features of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) infection, including those based on assessing the state of the intestinal microbiota and permeability.

Research motivation

To study the clinical features of the COVID-19 in patients with mild and moderate severity at the stage of hospitalization.

Research objectives

The objective of this clinical study was to determine the role of hepatobiliary injury, intestinal permeability disorders, and changes in composition of the microbiota in the development of systemic inflammation in patients with SARS-CoV-2 infection.

Research methods

The study was performed in 80 patients with mild and moderate severity of COVID-19. The scope of the examination included traditional clinical, laboratory, biochemical, instrumental, and radiation studies, as well as original methods for studying microbiota and intestinal permeability.

Research results

The clinical and biochemical features, manifestations of systemic inflammation, and intestinal microbiome changes in patients with mild and moderate severity were identified.

Research conclusions

This study highlights the role of intestinal permeability and microbiota as the main drivers of gastroenterological manifestations and increased COVID-19 severity.

Research perspectives

Our study showed that there is a change in the composition of the intestinal microflora, an increase in zonulin in feces, and intestinal dysfunction, which might be connected to COVID-19. We believe that additional studies should give more promising results. We also suggest that the use of probiotics, prebiotics, short chain fatty acids might show the success in treating intestinal dysbiosis caused by SARS-CoV-2 infection. If the effectiveness of these drugs is confirmed, the results can be used to complement the algorithms for COVID-19 treatment.
