Comparison of the Efficacy of Sofosbuvir and Kaletra on the Outcome of COVID-19. Is Sofosbuvir A Potential Treatment For COVID-19?

The COVID-19 is a family of large enveloped non-segmented positive-sense RNA viruses which was first reported in December 2019 in Wuhan, China with a cluster of unexplained pneumonia. Although various medications have been tried to manage the COVID-19 pandemic, there is no exclusive medication or vaccine so far. In this study, we aimed to focus on the effectiveness of Hydroxychloroquine + Kaletra (lopinavir/ritonavir) versus Hydroxychloroquine + Sofosbuvir in patients hospitalized with COVID-19 to given the urgent need for an effective drug against SARS-CoV-2 in the current pandemic context.

Fifty-four eligible patients with moderate to severe COVID-19 symptoms, according to the WHO criteria entered the study. Patients were randomized into two treatment groups. Thirty-two patients received Hydroxicholoroquine (400 mg stat) and Kaletra (400/100 mg q 12 h) as a control group (group A) and the trial group of 22 patients, received Hydroxicholoroquine (200 mg q 12 h) plus Sofosbuvir (400 mg daily) (group B) for a period of 7 to 14 days. Eventually, collected data included demographic characteristics, underlying diseases, clinical symptoms, laboratory data, and mortality were analyzed.

There was no significant difference in age, sex, and underlying diseases between the two groups. There was no significant statistical difference between the two groups on the seventh day of treatment in terms of cough relief, leukocyte count, and improvement of lymphopenia however in terms of the time of defervescence of fever, there was a significant difference between the two groups.

Therefore, it can be said that our study is one of the first studies in the world to evaluate the effectiveness of sofosbuvir in the treatment of patients with COVID-19. According to our results, although Kaletra was assumed as an effective therapy, its superiority over Sofosbuvir was confined to the earlier effervescence of the 7-day fever and sofosbuvir can be used as an effective treatment, especially in patients with underlying heart disease who are at risk for arrhythmias with Kaletra.
