Obstructive Sleep Apnea as a Risk Factor for COVID-19 Severity-The Gut Microbiome as a Common Player Mediating...

Area of Science:

• Infectious Diseases
• Pulmonology
• Gastroenterology

Background:

• SARS-CoV-2, the virus causing COVID-19, has led to millions of deaths globally.
• COVID-19 severity ranges from mild symptoms to fatal acute respiratory distress syndrome.
• Risk factors like age, hypertension, diabetes, and obesity are linked to severe COVID-19 outcomes.

Purpose of the Study:

• To investigate obstructive sleep apnea (OSA) as a potential independent risk factor for severe COVID-19.
• To explore the interrelationships between COVID-19, OSA, and gut microbiota.
• To evaluate the role of gut dysbiosis and barrier dysfunction in COVID-19 severity.

Main Methods:

• A comprehensive literature review was conducted.
• The review focused on the interactions between OSA, COVID-19, and gut microbiota.
• Analysis of existing research on risk factors and disease mechanisms.

Main Results:

• Obstructive sleep apnea (OSA) may be an independent risk factor for worse COVID-19 clinical outcomes.
• Shifts in gut microbiota are associated with both COVID-19 and OSA.
• These microbial shifts may promote bacterial translocation through a compromised gut barrier, fostering systemic inflammation.

Conclusions:

• OSA may contribute to increased severity of COVID-19.
• Gut dysbiosis and intestinal barrier dysfunction are potential mechanisms linking OSA and severe COVID-19.
• Targeting gut microbiota and tight junction dysfunction could offer novel strategies for risk detection and adjuvant therapy.
