Purpose: To compare the clinical efficacy between peramivir and oseltamivir in hospitalized patients with influenza.
Patients and Methods: Retrospective cohort study examined data from 542 adult patients with laboratory-confirmed seasonal influenza hospitalized in five teaching hospitals and one secondary hospital between August 2017 and May 2018. The main outcome was the defervescence rate within 3 days from the first administration of peramivir or oseltamivir. The secondary outcomes were mortality and duration of hospitalization/intensive care unit (ICU) stay.
Results: Of the 542 enrolled patients, 251 were administered the standard dose of peramivir (300 mg, single dose), 42 were administered peramivir at doses exceeding 300 mg, and 249 were administered oseltamivir (75 mg, twice daily for 5 days). There were more ICU and pneumonia cases and older patients in the peramivir group, especially the high-dose group. The Charlson comorbidity index (CCI) scores were similar among the three groups. There were no significant differences in defervescence rates within 3 days between the three groups. The mortality and duration of hospital and ICU stays also did not differ significantly. The factors associated with 30-day mortality were ICU admission, high CCI score, and pneumonia.
Conclusion: Treatment of influenza with either peramivir or oseltamivir in hospitalized adults resulted in generally similar clinical outcomes. Peramivir treatment showed good clinical response in influenza patients with pneumonia or admitted to the ICU.
