Introduction: Favipiravir is a repurposed drug to treat coronavirus 2019 . Due to a lack of available real-world data, we assessed its effectiveness and safety in moderately to critically ill COVID-19 patients. Methods: This retrospective study was conducted in two public/specialty hospitals in Saudi Arabia. We included patients !18 years) admitted April-August 2020 with confirmed SARS-CoV-2 diagnosed by real-time polymerase chain reaction (RT-PCR) from nasopharyngeal swab. Patients received either favipiravir (1800 mg or 1600 mg twice daily loading dose, followed by 800 mg or 600 mg twice daily) or supportive-care treatment. Patients were excluded if they were outside the study period, classified as having a mild form of the disease per WHO criteria, or had an incomplete patient file. Kaplan-Meier (KM) models were used to estimate median time to discharge. Discharge ratios, progression to mechanical ventilation, and mortality outcomes were estimated across the severity spectrum using Cox proportional-hazards models. As a sensitivity analysis, we performed propensity score-matching (PSM) analysis. Results: Overall, median time to discharge was 10 days (95%CI ¼ 9-10) in the favipiravir arm versus 15 days (95%CI ¼ 14-16) in the supportive-care arm. The accelerated discharge benefit was seen across the COVID-19 spectrum of severity. The adjusted discharge ratio was 1.96 (95%CI ¼ 1.56-2.46). Progression to mechanical ventilation was slower with favipiravir (HR adj ¼ 0.10, 95%CI ¼ 0.04-0.29). There was no significant effect on mortality (HR adj ¼ 1.56, 95%CI ¼ 0.73-3.36). There was a statistically non-significant trend toward worse outcomes in the critical category (HR adj ¼ 2.80, 95%CI ¼ 0.99-7.89). Age was an independent risk factor for mortality in mechanically ventilated patients. PSM analyses confirmed these findings. Conclusion: Favipiravir was associated with clinical benefits, including accelerated discharge rate and less progression to mechanical ventilation; however, no overall mortality benefits were seen across the severity spectrum.

The management of immune thrombocytopenic purpura (ITP) involves several lines of therapy such as corticosteroids and intravenous immunoglobulin. With the emergence of novel therapies such as thrombopoietin receptor agonists (TPO-RAs), there has been a shift in treatment modalities. Eltrombopag and romiplostim have proven to be effective in the management of ITP through clinical studies, but their safety in pregnancy remains uncertain. The purpose of the study is to review the literature to evaluate the safety of TPO-RAs in pregnant women. Ten case reports and a cohort study pertaining to the use of TPO-RAs in pregnancy were obtained. According to the reported cases and prospective study, the use of eltrombopag and romiplostim appears to be relatively safe in the first, second, and third trimesters, as there were no reported congenital malformations. Low fetal birth weight has been observed following the administration of eltrombopag during the second trimester, whereas preterm birth has occurred following the administration of eltrombopag in the third trimester. Eltrombopag and romiplostim seem relatively safe. Further studies are necessary to clarify their safety during pregnancy.
