Summary |
Background and objectives |
A notable proportion of COVID-19 patients need statins for their co-existing conditions. Statins possess several anti-inflammatory properties. We have attempted to describe potential association of exposure to statins and severity of COVID symtpoms in a historical study in hospitalized COVID-19 patients.
Methods |
This single-center, historical cohort study was performed in Baharloo hospital as a referral hospital for COVID-19 patients in Tehran. Patients were divided into two groups; 163 statins users and 547 non-users. Mortality rate, intensive care unit (ICU) admission and length of hospitalization were compared between studied groups. In addition, during the investigation, pre-existing conditions were evaluated for groups. If a significant difference was observed between groups, the feature was considered in the adjustment of the odds ratio.
Results |
At the beginning, statistical analysis study showed that statins users had significantly (p<0.0001) higher mortality rate, ICU admission and length of hospitalization. But after implementation of variables such as age, sex, diabetes, hypertension status, stroke, dyslipidemia, cardiovascular diseases, chronic kidney disease (CKD), corticosteroids, renin-angiotensin-aldosterone axis inhibitors and proton pump inhibitors (PPIs) for adjustment of the odds ratio, a considerable alteration appeared in the studied values. Following adjustment of odds ratio it was shown that statins did not change mortality (95% CI, OR 0.71 (0.41–1.22), p=0.22), ICU admission (95% CI, OR 1.05 (0.66–1.66), p=0.835) and length of hospitalization (95% CI, OR 1.30 (0.78–2.17), p=0.311). In addition, we found that statins could not decrease inflammatory markers in COVID-19 infected patients.
Conclusion |
The use of statins did not seem to change outcomes in COVID19.
