Analysis of adverse reactions of lopinavir/ritonavir in the treatment of coronavirus disease 2019

Objective: To explore the occurrence of adverse reactions of lopinavir/ritonavir (LPV/r) in the treatment of coronavirus disease 2019 (COVID-19) Methods: The medical records of patients with COVID-19 who received LPV/r treatment in the Fourth People's Hospital of Nanning from January 24th to February 6th, 2020 were collected and the occurrence of adverse events during the treatment was retrospectively analyzed According to the 5 principles of adverse drug reaction correlation evaluation proposed in the Handbook of Adverse Drug Reaction Reporting and Monitoring in China, adverse events that were certainly related, probably related, and possibly related to LPV/r were defined as LPV/r-related adverse reactions The incidence of adverse reactions was calculated and the main clinical manifestations and severity of adverse reactions [grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (life-threatening), and grade 5 (death);grade 3-5 was defined as severe adverse reaction] were analyzed Results: A total of 28 patients were enrolled in the analysis, including 13 males and 15 females, aged from 18 to 70 years with an average age of 44 years The courses of treatment with LPV/r of patients ranged from 2 to 12 days, with a median course of 6 days Of the 28 patients, 18 developed LPV/r related adverse reactions, with an incidence of 64 3% The LPV/r-related adverse reactions in 18 patients included gastrointestinal reactions in 14 patients (grade 1 in 13 patients and grade 2 in 1 patient), bradycardia in 2 patients (grade 2 in both patients), and acute hemolysis in 1 patient (grade 3), and liver injury in 1 patient (grade 3), and no grade 4 or 5 adverse reactions occurred The incidence of severe adverse reactions was 7 1% Thirteen patients with grade 1 adverse reactions did not affect the treatment, and the symptoms were relieved after 2-7 days of continuous medication LPV/r was discontinued in 5 patients with grade 2 or 3 adverse reactions, 4 of whom received symptomatic treatment, and the symptoms disappeared 2-10 days later Conclusions: The incidence of adverse reactions in COVID-19 patients treated with LPV/r in our hospital was 64 3% LPV/r mainly leads to mild gastrointestinal reactions and can also lead to bradycardia, acute hemolysis, and liver injury Blood routine, liver function, and electrocardiogram need to be monitored during the treatment Copyright © 2020 by the Chinese Medical Association
