Insights
Statins did not worsen outcomes for older, sicker COVID-19 patients. Adjusted for age and comorbidities, statin therapy (ST) showed favorable survival functions compared to no statin therapy (NST).
Area of Science:
- Cardiology
- Infectious Diseases
- Pharmacology
Background:
- The COVID-19 pandemic necessitates effective treatments for the inflammatory response.
- Statins, known for anti-inflammatory properties, were investigated for potential benefits in COVID-19 patients.
- The specific impact of statin therapy on COVID-19 patient outcomes remained underexplored.
Purpose of the Study:
- To evaluate the effect of pre-admission statin therapy on COVID-19 patient outcomes.
- To compare clinical characteristics and survival functions between COVID-19 patients on statin therapy (ST) and those not on statin therapy (NST).
Main Methods:
- Retrospective analysis of 501 adult COVID-19 patients admitted to hospitals in Ferrara.
- Patients were divided into ST and NST groups based on medication at admission.
- Comparison of demographic, clinical, laboratory data, and COVID-19 outcomes between the two groups.
Main Results:
- ST patients were older, had more comorbidities, lower procalcitonin, and higher CPK levels.
- Male sex and Charlson Comorbidity Index (CCI) predicted the need for care intensification.
- Age was a predictor of in-hospital and 100-day mortality; survival functions differed between groups.
Conclusions:
- Despite older age and higher comorbidity burden, ST patients exhibited similar survival functions to NST patients over 100 days.
- When adjusted for age and CCI, statin therapy was associated with considerably more favorable survival functions.
- Pre-admission statin use may offer a survival benefit in COVID-19 patients, particularly when accounting for age and comorbidities.
Introduction:
The outbreak by SARS-CoV-2 has rapidly spread worldwide. The need for specific treatments to adequately stop the inflammatory response and its sequelae is day by day more urgent and many therapeutic strategies were performed since COVID-19 burst in the last months. Statins were thought to be effective against this novel coronavirus for their anti-inflammatory properties, even if the real effects on COVID patients are still partially unexplored.
Methods:
We retrospectively evaluated 501 adult patients, consecutively admitted to the two COVID-hospitals of Ferrara's territory, and divided them into two groups: ST = patients on statin therapy on admission and NST=patients not on statin therapy on admission. We searched for differences between groups in terms of anamnestic, clinical and laboratory data and then in terms of COVID-19 outcomes.
Results:
We found significant differences between groups in terms of age, comorbidities, procalcitonin and CPK serum levels: ST patients were older, more comorbid, with lower procalcitonin and higher CPK serum levels. Male sex was, together with the Charlson Comorbidity Index, an independent predictor of needing intensification of care, while age only was a good predictor of in-hospital and 100-day mortality. Differences were also found in the survival functions between the two groups.
Conclusions:
After a period of observation of 100 days, ST patients, despite their older age and their greater load of comorbidities, have similar survival functions to NST patients. If adjusted for age and CCI the survival functions of ST group are considerably more favourable than those of the second group.
