Favipiravir Experience in COVID-19 Patients at a Tertiary Center Intensive Care Unit.

Abstract

ObjectivesThe aim of this study was to compare intensive care unit (ICU) and overall hospital mortality in patients treated with favipiravir and lopinavir-ritonavir for COVID-19.MethodsData were collected retrospectively between March 10 and May 10, 2020, from patients’ records admitted to ICU due to COVID-19. Laboratory data, clinical characteristics, ICU and hospital mortality, ICU and hospital length of stay were compared in patients treated with favipiravir and lopinavir-ritonavir.ResultsA total of 100 patients’ data were investigated. Favipiravir was used as the treatment for 85% of patients, with the rest treated with lopinavir-ritonavir. Clinical and laboratory data of both antiviral treatment groups were similar. Length of hospital stay was 16 (9–24) days with favipiravir and 8.5 (5–12.5) days with lopinavir-ritonavir (p=0.002). Length of ICU stay for favipiravir and lopinavir-ritonavir groups were 8 (5–15) days and 4 (3–9) days, respectively (p=0.011). ICU mortality was 65.9% for the favipiravir and 80% for lopinavir-ritonavir (p=0.002). Hospital mortality for favipiravir and lopinavir-ritonavir was 67.1% and 80%, respectively (p=0.001).ConclusionThe mortality in patients treated with favipiravir was less than patients treated with lopinavir-ritonavir. Favipiravir needs more attention and trials for its effect to be confirmed.
