Atorvastatin efficacy in the management of mild to moderate hospitalized COVID-19: a pilot randomized triple-blind placebo-controlled clinical trial.

BACKGROUND Statins are first-line lipid-lowering agents with tolerable adverse reactions, low cost, and high availability worldwide. The potent anti-inflammatory, antioxidant, anti-thrombotic and immunomodulatory effects of statins propose them as an option to face COVID-19 infection.

OBJECTIVE In this randomized triple-blind placebo-controlled clinical trial, we have investigated the atorvastatin efficacy in the management of mild to moderate hospitalized COVID-19 patients.

METHODS In this study, 52 mild to moderate hospitalized COVID-19 patients who fulfilled the inclusion criteria were allocated to the treatment group to receive 40 mg atorvastatin orally once daily for two weeks (n=26) or the placebo group (n=26). Patients' symptoms and laboratory investigations were assessed at baseline and during the follow-up period. We also evaluated the duration of hospitalization and supplemental oxygen therapy as endpoints.

RESULTS After 14-day of follow-up, the oxygen saturation (SaO2) was significantly higher, and the serum high sensitivity C-reactive protein (hs-CRP) level was lower in the treatment group compared with the placebo group. Moreover, at the end of the follow-up in the treatment group, the lymphocyte count was higher, and the duration of symptom resolution was shorter but not significant. Additionally, in the treatment group length of supplemental oxygen therapy and hospitalization duration were meaningfully shorter. Our results revealed that the mortality rate was almost twice higher in the placebo group compared with the treatment group, without any significant adverse drug reaction.

CONCLUSION Atorvastatin significantly reduces supplemental oxygen need, hospitalization duration, and serum hs-CRP level in mild to moderate hospitalized COVID-19 patients.
