ABSTRACT
Objetivo: Examinar e mapear as evidências científicas sobre a eficácia do uso de ivermectina e atazanavir no tratamento de COVID-19. Metodologia: Scoping Review, baseado nos procedimentos recomendados pelo Instituto Joanna Briggs. Estabeleceu-se a pergunta norteadora: "Quais são as evidências científicas sobre o uso de ivermectina e atazanavir no tratamento de pacientes com sintomas leves de COVID-19?". Foram realizadas buscas em seis bases de dados nacionais e internacionais, sobre trabalhos publicados até dezembro de 2022. Dos 357 estudos encontrados, 22 foram selecionados para leitura na íntegra, resultando em uma amostra final de 11 estudos analisados. Resultados: As 11 publicações analisadas foram publicadas de 2020 a 2022 durante período pandêmico, de âmbito nacional e internacional com delineamento de estudos experimentais, do tipo ensaio clínico com randomização. Apenas 03 estudos (25%) testaram o atazanavir como intervenção conjugada a outras drogas, não evidenciando melhorias significativas em relação ao seu uso. Já no tratamento com Ivermectina, dos oito (75%) estudos que a testaram, apenas três (37,5%) recomendaram seu uso e cinco (62,5%) não suportam seu uso para tratamento de COVID-19 leve. O tempo de resolução dos sintomas variou de 8 a 10 dias nos braços tratados com ivermectina e em média 07 dias no tratamento com atazanavir. Não se detectou eventos adversos graves relacionados ao uso das duas drogas. Conclusão: As evidências que recomendavam o uso de ivermectina datam do início do período pandêmico, 2020, mas posteriormente, com a realização de ensaios clínicos robustos e controlados, novas evidências não suportam o uso de ivermectina e atazanavir no tratamento de COVID-19 leve mostrando que não houve diferença no tempo de resolução dos sintomas, na taxa de mortalidade, taxa de internação na UTI e tempo de hospitalização.
Objective: To examine and map the scientific evidence on the effectiveness of using ivermectin and atazanavir in the treatment of COVID-19. Methodology: Scoping Review, based on the procedures recommended by the Joanna Briggs Institute. The guiding question was established, "What is the scientific evidence on the use of ivermectin and atazanavir in the treatment of patients with mild symptoms of COVID-19?" Searches were conducted in six national and international databases on papers published until December 2022. Of the 357 studies found, 22 were selected for reading in full, resulting in a final sample of 11 studies analyzed. Results: The 11 publications analyzed were published from 2020 to 2022 during pandemic period, of national and international scope with experimental study design, of clinical trial type with randomization. Only 03 studies (25%) tested atazanavir as a combined intervention with other drugs, showing no significant improvements in relation to its use. As for the treatment with Ivermectin, of the eight (75%) studies that tested it, only three (37.5%) recommended its use and five (62.5%) did not support its use for treating mild COVID-19. The time to symptom resolution ranged from 8 to 10 days in the ivermectin-treated arms and on average 07 days in the atazanavir treatment. No serious adverse events related to the use of the two drugs were detected. Conclusion: evidence recommending the use of ivermectin dates back to the beginning of the pandemic period, 2020, but subsequently, with robust controlled clinical trials, new evidence does not support the use of ivermectin and atazanavir in the treatment of mild COVID-19 showing that there was no difference in time to symptom resolution, mortality rate, ICU admission rate, and length of hospital stay.

Resultados: Las 11 publicaciones analizadas fueron publicadas entre 2020 y 2022 durante el periodo pandémico, de ámbito nacional e internacional con diseño de estudio experimental, de tipo ensayo clínico con aleatorización. Apenas 03 estudios (25%) probaron el atazanavir como intervención combinada con otras drogas, sin evidenciar mejoras significativas en relación con su uso. En cuanto al tratamiento con Ivermectina, de los ocho (75%) estudios que la probaron, sólo tres (37,5%) recomendaron su uso y cinco (62,5%) no apoyaron su uso para tratar la COVID-19 leve. El tiempo transcurrido hasta la resolución de los síntomas osciló entre 8 y 10 días en los brazos tratados con ivermectina y una media de 07 días en el tratamiento con atazanavir. No se detectaron acontecimientos adversos graves relacionados con el uso de los dos fármacos. Conclusión: las pruebas que recomiendan el uso de ivermectina se remontan al inicio del periodo pandémico, 2020, pero posteriormente, con ensayos clínicos controlados sólidos, las nuevas pruebas no apoyan el uso de ivermectina y atazanavir en el tratamiento de la COVID-19 leve, lo que demuestra que no hubo diferencias en el tiempo hasta la resolución de los síntomas, la tasa de mortalidad, la tasa de ingreso en la UCI y la duración de la estancia hospitalaria.
ABSTRACT
OBJECTIVE: To describe the profile and temporal variation of hospital admissions and deaths due to severe acute respiratory syndrome (SARS) caused by COVID-19 in Piauí, Brazil, according to place of hospitalization. METHODS: We performed a descriptive study using data from the Influenza Surveillance Information System between 2020 and 2021. Case fatality ratio among hospital records with outcome and respective 95% confidence intervals (95%CI) were calculated. RESULTS: We included 12,649 individuals who were mostly male (57.1%), Black (61.2%) and had one or two comorbidities (30.5%). Case fatality ratio among hospital records with outcome was higher in the state's interior region than in its capital, with proportion of 44.1% (95%CI 42.0;46.3) for those who were hospitalized, 82.3% (95%CI 79.7;84.8) for those admitted to intensive care units and 96.6% (95%CI 94.9;97.8) for those undergoing invasive mechanical ventilation. CONCLUSION: The study enabled characterization of the profile of SARS hospitalizations due to COVID-19 in Piauí and demonstrated high case fatality ratio, among hospital records with outcome, which remained high during the study period, especially in the interior of the state.
