The relationship between Covid-19 and mucociliary clearance

Area of Science:

• Otolaryngology
• Infectious Diseases
• Respiratory Physiology

Background:

• The impact of COVID-19 on nasal mucociliary clearance (MCC) remains largely uncharacterized.
• Understanding this relationship is crucial for managing respiratory symptoms and recovery.

Purpose of the Study:

• To investigate the association between COVID-19 infection and nasal MCC.
• To explore how factors like smoking, symptoms, and treatment influence this relationship.

Main Methods:

• A comparative study involving 36 hospitalized COVID-19 patients and 36 healthy controls.
• Nasal MCC was assessed using the standardized Saccharin test in both groups.

Main Results:

• No significant differences in age or gender were observed between the COVID-19 patient group and the control group.
• Nasal MCC time was significantly prolonged in COVID-19 patients (19.18 ± 10.84 min) compared to controls (13.78 ± 8.18 min; p=0.003).

Conclusions:

• COVID-19 infection independently prolongs nasal MCC time, irrespective of patient age.
• Corticosteroid therapy is recommended for COVID-19 treatment due to potential benefits in symptom relief and improved nasal MCC duration.
