Inflammatory effect on the gastrointestinal system associated with COVID-19

Area of Science:

• Gastroenterology
• Virology
• Microbiome Research

Background:

• The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) pandemic primarily impacts the respiratory system.
• A significant subset of infected individuals experiences gastrointestinal (GI) symptoms.
• Existing research highlights the connection between GI symptoms and COVID-19 severity.

Purpose of the Study:

• To review the mechanisms of gut damage caused by SARS-CoV-2 infection.
• To explore the impact of SARS-CoV-2 on the liver and pancreas.
• To summarize the role of host factors and gut microbiota dysbiosis in severe COVID-19.

Main Methods:

• Literature review of studies on SARS-CoV-2 and gastrointestinal manifestations.
• Analysis of mechanisms linking viral infection to organ damage.
• Examination of host factors and microbiome alterations in COVID-19 patients.

Main Results:

• SARS-CoV-2 infection can lead to direct or indirect gut damage.
• The virus may affect liver and pancreatic functions.
• Intestinal microbiota dysbiosis is a notable finding in severe COVID-19 cases.

Conclusions:

• Gastrointestinal symptoms are a relevant clinical manifestation of COVID-19.
• Understanding gut damage mechanisms is crucial for managing severe disease.
• Microbiota dysbiosis may contribute to COVID-19 severity, warranting further investigation.
