This study was conducted to assess the efficacy of nirmatrelvir/ritonavir treatment in patients with coronavirus disease 2019 (COVID-19), particularly those aged 60 years and older. Using real-world data, the period during which the BN.1 Omicron variant was dominant was compared to the period dominated by the BA.5 variant. Methods: In this retrospective cohort study, data were collected regarding 2,665,281 patients infected with severe acute respiratory syndrome coronavirus 2 between July 24, 2022, and March 31, 2023. Propensity score matching was utilized to match patients who received nirmatrelvir/ ritonavir in a 1:4 ratio between BN.1 and BA.5 variant groups. Multivariable logistic regression analysis was employed to assess the effects of nirmatrelvir/ritonavir within these groups. Results: Compared to the prior period, the efficacy of nirmatrelvir/ritonavir did not significantly differ during the interval of Omicron BN.1 variant dominance in the Republic of Korea. Among patients treated with nirmatrelvir/ritonavir, a significantly lower risk of mortality was observed in the BN.1 group (odds ratio [OR], 0.698; 95% confidence interval [CI], 0.557–0.875) compared to the BA.5 group. However, this treatment did not significantly reduce the risk of severe or critical illness, including death, for those in the BN.1 group (OR, 0.856; 95% CI, 0.728–1.007). Conclusion: Nirmatrelvir/ritonavir has maintained its effectiveness against COVID-19, even with the emergence of the BN.1 Omicron subvariant. Consequently, we strongly recommend the administration of nirmatrelvir/ritonavir to patients exhibiting COVID-19-related symptoms, irrespective of the dominant Omicron variant or their vaccination status, to mitigate disease severity and decrease the risk of mortality.

AbstractAbstract PDF

To evaluate the impact of 3 treatment regimens upon health-related quality of life and work productivity using patient-reported outcomes (PROs) in chronic hepatitis C infected patients: sofosbuvir (SOF) + daclatasvir (DCV); SOF + DCV + ribavirin (RBV); SOF + simeprevir (SMV).


4 questionnaires were used to evaluate PROs before, during and after treatment: Short Form-36 (SF-36), Chronic Liver Disease Questionnaire (CLDQ) - hepatitis C virus (HCV), Work Productivity and Activity Index, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F).


Of the global sample of 55 patients included in this study; SOF + DCV (n = 10); SOF + DCV + RBV (n = 29); SOF + SMV (n = 16) all had a statistically significant improvement in SF-36, CLDQ and FACIT-F scores during and post-treatment. No statistically significant differences in the PRO questionnaire values were observed between the distinct treatment regimens. The SOF and SMV patient groups presented higher mean PRO variations during and post-treatment, compared to the other groups: SF-36 functional capacity (16.1); SF-36 mental health (21.4); CLDQ activity (1.8); CLDQ emotional function (1.2); FACIT-F physical well-being (8.0); Total FACIT-F (21.6).


Treatment with SOF + DCV, with or without RBV, results in an improved PRO similar to treatment with SOF + SMV in chronic hepatitis C patients.
