Resumo

Introdução: a pandemia de covid-19 exigiu o desenvolvimento acelerado de métodos de tratamento eficazes. Dentre esses métodos, destacamos o anticorpo monoclonal, uma técnica de imunização passiva com resultados promissores. Objetivos: relatar a eficácia do tratamento para covid-19 com anticorpo monoclonal atualmente. Material e métodos: realizou-se uma revisão de literatura nas plataformas de pesquisa PubMed e SciELO combinando os seguintes descritores em inglês: Monoclonal Antibodies, Coronavirus Infections, Immunotoxins e “Antibodies, Bispecific”. Após a pesquisa inicial, localizou-se 52 artigos científicos de estudos clínicos randomizados completos gratuitos e publicados há 1 ano. Por fim, excluiu-se os textos não relacionados ao tema ou contendo dados secundários. Resultados: obteve-se 6 textos e segmentou-se os resultados em critérios clínicos para verificar a eficácia do tratamento. Dessa forma, verificou-se o total de 1.514 pacientes avaliados no conjunto dos textos; das intervenções: 3 experimentos utilizaram tocilizumabe 8 mg/kg; 1 combinou favipiravir 600-1600 mg duas vezes ao dia com tocilizumabe 4-8 mg intravenosa; 1 utilizou o anticorpo neutralizante LY-CoV555 em uma das três doses (700 mg, 2.800 mg ou 7.000 mg); e 1 utilizou a combinação de anticorpos monoclonais REGN-COV2 em uma dose de 2,4 g (dose baixa) ou REGN-COV2 em uma dose de 8,0 g (dose alta) aplicados por infusão intravenosa. Sobre a eficácia, em síntese, apontou-se que a utilização de favipiravir com tocilizumabe obteve resultados animadores em relação a inflamação pulmonar e inibir deterioração pela doença, porém a utilização isolada de tocilizumabe não demonstrou melhoras na redução do tempo de remissão da doença ou do número de infectados, além de poder ser maléfico em uso prolongado, apesar disso, houve melhora em relação à mortalidade e necessidade de uso de ventilação mecânica; quanto a utilização de LY-CoV555 e REGN-COV2 houve redução da carga viral, como também, acelerou o declínio natural da doença. Conclusão: a utilização de anticorpos monoclonais pode ser eficaz para diminuir a mortalidade em pacientes internados, evitar a necessidade de ventilação mecânica e acelerar recuperação dos pacientes acometidos por covid-19, porém ainda há a necessidade de novas pesquisas para sustentar esses resultados.
