Analysis of COVID-19 patient outcomes with molnupiravir treatment and the role of risk factors: a single-centre retrospective descriptive study.

OBJECTIVE

This study aims to describe the outcomes of COVID-19 patients treated with molnupiravir and to explore the associations with various risk factors.

METHODS

We conducted a single-centre, descriptive, retrospective study without a comparison group.

RESULTS

Out of 141 patients, 70 (49.7%) required follow-up outpatient care. In the subgroup of 66 (46.8%) hospitalized patients, 28 (19.9%) developed interstitial viral pneumonia, with 6 (4.3%) deaths. Unvaccinated patients had a higher incidence of pneumonia (p = 0.020), and obesity was a significant risk factor for both pneumonia (p = 0.001) and mortality (p = 0.011). Patients over 60 years (p = 0.040) and those with cardiovascular diseases (p = 0.026) also had increased pneumonia risk. Male sex was associated with a higher risk of death (p = 0.020).

CONCLUSION

Molnupiravir treatment was linked to reduced risks of hospitalization and death, particularly in high-risk patients. Vaccination provided additional protection, and obesity obstructive pulmonary disease and autoimmune diseases were significant risk factors for severe outcomes.
