• No studies evaluating the association between statins and outcomes of patients with seasonal influenza have been performed since the 2007–2008 and the 2009 pandemic H1N1 influenza seasons. All consecutive hospitalized patients between October 2017 and April 2018, diagnosed with laboratory-confirmed influenza A and B virus, were included. Patients were divided into two groups: statin and non-statin users. Outcomes were 30- and 90-day mortality, complications (pneumonia, myocarditis, encephalitis, intensive care unit (ICU) transfer, mechanical ventilation, vasopressor support), length of hospital stay, and readmission rates. A multivariate analysis was performed to adjust for mortality risk factors. To compare the groups, we matched patients to the nearest neighbor propensity score. Of the 526 patients ill with influenza A (201/526) and B (325/526), 36% (188/526) were statin users; 64% (338/526) were not. Statin users were older (78 vs.70; p  = < 0.05) and suffered from more comorbidities (Charlson comorbidity scores of 6 vs.4; p  < 0.005). The 30-day mortality rate among statin vs. non-statin users was 6% vs. 8% ( p  = 0.3). On multivariate analysis, statin use was not associated with mortality benefit (OR = 0.67 (0.29–1.36)). After propensity score matching, the results were unchanged (OR = 0.71 (0.29–1.71)). Statin users were diagnosed with less complicated diseases as they were less likely to receive vasopressor support, mechanical ventilation, and/or transfer to the ICU. Although statin users were significantly older and exhibited more comorbidities, 30-day mortality rates did not differ between statin users and non-users, which may signify a protective role of statins on seasonal influenza patients. Further studies performed during different influenza seasons and different subtypes are essential.
