ABSTRACT C3 glomerulopathies are a rare group of glomerular diseases resulting from excessive activation of the alternative complement pathway. The pathogenesis involves genetic, acquired, or immunologic defects in regulators of the alternative complement pathway. Currently, these diseases have a chronic course with progression to end-stage renal disease in up to 50% of adult patients. We report a case of a young woman who presented with nephrotic syndrome and renal disfunction. During follow-up, the diagnosis of C3 glomerulopathy associated with complement factor I deficiency was established. After relapse of nephrotic proteinuria, immunosuppressive therapy with mycophenolate mofetil and glucocorticoid was added to supportive care. There is no disease-specific therapy for C3 glomerulopathies, and treatment is focused on reducing proteinuria and renal inflammation. Supportive treatment with ACE inhibitors or angiotensin receptor blockers is the first-line therapy. Immunosuppressive therapy with mycophenolate mofetil plus corticosteroids is associated with higher chances of clinical remission and lower risk of kidney failure. Complement targeting therapies, such as eculizumab, avacopan, danicopan, iptacopan, and pegcetacoplan, are being studied as potential new therapeutic options. This article highlights the need for more clinical trials to test new therapeutic agents, as well as to better understand the heterogeneity of the disease and its long-term outcomes.

Resumo Objetivo: analisar indicadores de qualidade e conteúdo técnico dos vídeos postados na plataforma YouTube, para leigos, sobre reanimação cardiopulmonar em adultos e sua produção audiovisual quanto aos princípios do letramento digital em saúde. Método: estudo descritivo, exploratório, que selecionou vídeos gravados entre dezembro de 2015 e abril de 2021. Foram analisados por indicadores da produção de material audiovisual, considerando as diretrizes da American Heart Association e os princípios do letramento digital em saúde. Foi realizada estatística descritiva e inferencial. Resultados: dos 121 vídeos analisados, 26 não atenderam qualquer indicador sobre ressuscitação cardiopulmonar; quatro atingiram 81% de conformidade; oito vídeos, 79%; nove vídeos, 69% e 74 vídeos de seis a 63%. De acordo com os princípios do letramento digital em saúde, um vídeo atendeu 85% dos indicadores; 81 vídeos atenderam de 50 a 80% e 39 vídeos, de 10 a 49%. Foi identificada correlação positiva entre letramento e ressuscitação cardiopulmonar. Conclusão: nenhum vídeo apresentou 100% de conformidade com as diretrizes da American Heart Association. A falta de mecanismos de fiscalização e controle sobre conteúdos relacionados à saúde permite a publicação de vídeos equivocados, que têm sido utilizados como aprendizado pelas pessoas e podem perder o maior objetivo que é salvar vidas.

Abstract Objective: to analyze the quality indicators and technical content of the videos for lay people posted on the YouTube platform, on cardiopulmonary resuscitation in adults and their audiovisual production regarding the principles of digital health literacy. Method: a descriptive and exploratory study, which selected videos recorded between December 2015 and April 2021. They were analyzed by indicators of the production of audiovisual material, considering the American Heart Association guidelines and the principles of digital health literacy. Descriptive and inferential statistics were performed. Results: of the 121 videos analyzed, 26 did not comply with any indicator on cardiopulmonary resuscitation, four reached 81% compliance, eight videos reached 79%, nine reached 69% and 74 videos, from 6% to 63%. According to the principles of digital health literacy, one video met 85% of the indicators, 81 met from 50% to 80% and 39, from 10% to 49%. A positive correlation was identified between literacy and cardiopulmonary resuscitation. Conclusion: no video presented 100% compliance with the American Heart Association guidelines. The absence of mechanisms for supervision and control over health-related contents allows for the posting of mistaken videos, which have been used as a learning method by people and can thus miss their greatest goal: save lives.

Resumen Objetivo: analizar los indicadores de calidad y contenido técnico de los videos publicados en la plataforma YouTube, para legos, sobre reanimación cardiopulmonar en adultos y su producción audiovisual según los principios de la alfabetización digital en salud. Método: estudio descriptivo, exploratorio, que seleccionó videos grabados entre diciembre de 2015 y abril de 2021. Fueron analizados en función de los indicadores de producción de material audiovisual, considerando las directrices de la American Heart Association y los principios de la alfabetización digital en salud. Se realizó estadística descriptiva e inferencial. Resultados: de los 121 videos analizados, 26 no cumplieron con ninguno de los indicadores de reanimación cardiopulmonar; cuatro lograron un 81% de conformidad; ocho videos, 79%; nueve videos, 69% y 74 videos de seis a 63%. De acuerdo con los principios de la alfabetización digital en salud, un video cumplió con el 85% de los indicadores; 81 videos cumplieron del 50 al 80% y 39 videos del 10 al 49%. Se identificó una correlación positiva entre la alfabetización y la reanimación cardiopulmonar. Conclusión: ningún video cumplió el 100% de las directrices de la American Heart Association. La falta de mecanismos de supervisión y control sobre los contenidos relacionados con la salud permite la publicación de videos erróneos, que han sido utilizados como experiencia de aprendizaje por las personas y es probable que no cumplan con el principal objetivo, que es salvar vidas.
