RESUMO
Coronavirus disease 2019 (COVID-19) is still a global health issue with no certain treatment option. So far, various treatments have been suggested among which one can mention isotretinoin. The aim of the present study was to investigate the potential of this medication as a side treatment for COVID-19. This open-label controlled clinical trial with the approval ID of IRCT20190624043993N3 was conducted in Farabi Hospital, Kermanshah University of Medical Sciences, Kermanshah, Iran. Considering the inclusion and exclusion criteria, 52 patients diagnosed with COVID-19 were enrolled. The control group only received standard of care (SOC) treatment while the intervention arm received 40 mg per day of isotretinoin along with the SOC. The patients were followed until discharge. The results showed no death among the groups. The hospitalization duration in the intervention and SOC groups were 5.1 ± 2.29 and 5.1 ± 3.44 days, respectively with no statistical difference (P = 0.98). Moreover, the SpO2, pulse rate, respiratory rate, and blood pressure also showed no statistical difference neither at admission nor upon discharge (P > 0.05). The laboratory investigations showed that white blood cells, absolute lymphocyte count, hemoglobin value, and platelet count did not differ between the groups at admission or upon discharge (P > 0.05). According to the results, it seems that isotretinoin didn't act as a potent side therapy in patients with COVID-19. However, due to the small sample size, we suggest further investigations.
