Use of remdesivir for patients with Covid-19: a review article

SUMMARY The etiological agent of COVID-19, which causes severe respiratory diseases such as pneumonia and pulmonary insufficiency, has been confirmed as a new coronavirus, now known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). There is currently no authorized medication for the treatment of COVID-19. No vaccines have been authorized. Thus, this study aimed at conducting a review of the use of Remdesivir in patients with COVID-19. The following electronic databases were used MEDLINE, SCIELO, LILACS, and PUBMED. On May 1, Remdesivir received emergency use authorization from the Food and Drug Administration. Remdesivir is currently the most promising molecule in the treatment of COVID-19, taking into account its broad antiviral spectrum (considering the genetic sequences of the virus, it is expected to maintain activity against SARS-CoV-2). There is in vitro and in vivo information available for coronaviruses, as well as an extensive clinical safety database (from a clinical trial of the Ebola virus and in the context of the Monitored Emergency Use of Unregistered and Investigational Interventions - MEURI). Further studies are relevant as available data on the efficacy and safety of Remdesivir against SARS-nCoV-2 are limited.

RESUMO O agente etiológico da COVID-19, que causa doenças respiratórias graves, como pneumonia e insuficiência pulmonar, foi confirmado como um novo coronavírus, agora conhecido como coronavirus de síndrome respiratória aguda grave 2 (SARS-CoV-2). Não existem atualmente medicamentos autorizados para o tratamento de COVID-19, nem estão também autorizadas quaisquer vacinas. Assim, o estudo teve como objetivo realizar uma revisão sobre a utilização de Remdesivir em pacientes com COVID-19. As seguintes bases de dados eletrônicas foram utilizadas MEDLINE, SCIELO, LILACS e PUBMED. Em primeiro de maio, o Redemsivir recebeu autorização de uso de emergência da Food and Drug Administration. Remdesivir é presentemente a molécula promissora no tratamento da COVID-19 tendo em conta o seu largo espetro antiviral (considerando as sequências genéticas do vírus, é expectável que mantenha atividade contra o SARS-CoV-2). A informação in vitro e in vivo está disponível para os coronavírus, assim como a extensiva base de dados de segurança clínica (proveniente de ensaio clínico do vírus Ebola e no contexto do Monitored Emergency Use of Unregistered and Investigational Interventions - MEURI). A realização de novos estudos torna-se relevantes uma vez que os dados disponíveis são limitados sobre eficácia e segurança do Remdesivir contra SARS-nCoV-2.

Remdesivir-Warfarin Interaction: A Case Report.

Description A greater than 65-year-old Caucasian woman receiving long-term anticoagulation with warfarin for atrial fibrillation experienced a sudden rise in an international normalized ratio (INR) after she was started on remdesivir for management of 2019 Novel Coronavirus (COVID-19). Patient INR was maintained within the target therapeutic range of 2-3 with a warfarin dose of 11 mg/week before starting remdesivir. After 2 days of remdesivir therapy, the patient's INR increased significantly and remained elevated during the 5 day course of remdesivir therapy. Patient required an interruption of her warfarin therapy for 7 days, and her INR did not return to the targeted therapeutic INR range of 2-3 until day 5 from the last dose of remdesivir, despite no warfarin administration. A comprehensive PubMed/MEDLINE search did not find published literature documenting interaction between warfarin and remdesivir. We describe the first case report, to our knowledge, documenting a potential drug interaction between warfarin and remdesivir. The authors found that there is a probable interaction between warfarin and remdesivir when applying the Adverse Drug Reaction Probability Scale, Naranjo Scale. To reduce the risk of bleeding associated with excessive anticoagulation, clinicians should closely monitor INR, and adjust the warfarin dose accordingly when patients are receiving remdesivir and warfarin concomitantly.

Extracorporeal Membrane Oxygenation for COVID-19 Treatment in a Community Hospital.

Description Coronavirus disease 2019 (COVID-19) may result in severe acute respiratory disease syndrome (ARDS) and death. For COVID-19 patients failing mechanical ventilation, extra corporeal membrane oxygenation (ECMO) has been used with varying efficacy in academic medical centers and quaternary referral centers. We report the successful use of veno-venous (VV) ECMO to treat refractory ARDS due to COVID-19 in a community hospital setting with a survival to discharge rate of 71% over a 3 month period. In a community hospital with adequate resources, VV ECMO can be an effective rescue therapy for selected COVID-19 patients who fail all other available treatments.
