ABSTRACT

Currently, there are no evidence-based treatment options for long COVID-19, and it is known that SARS-CoV-2 can persist in part of the infected patients, especially those with immunosuppression. Since there is a robust secretion of SARS-CoV-2-specific highly-neutralizing IgA antibodies in breast milk, and because this immunoglobulin plays an essential role against respiratory virus infection in mucosa cells, being, in addition, more potent in neutralizing SARS-CoV-2 than IgG, here we report the clinical course of an NFκB-deficient patient chronically infected with the SARS-CoV-2 Gamma variant, who, after a non-full effective treatment with plasma infusion, received breast milk from a vaccinated mother by oral route as treatment for COVID-19. After such treatment, the symptoms improved, and the patient was systematically tested negative for SARS-CoV-2. Thus, we hypothesize that IgA and IgG secreted antibodies present in breast milk could be useful to treat persistent SARS-CoV-2 infection in immunodeficient patients.

ABSTRACT

ABSTRACT The Covid-19 pandemic brought several challenges to the healthcare system: diagnosis, treatment and measures to prevent the spread of the disease. With the greater availability and variety of diagnostic tests, it is essential to properly interpret them. This paper intends to help dialysis units concerning the use of clinical criteria and diagnostic tests for decision making regarding the discontinuation of isolation of patients with suspected or confirmed Covid-19, as well as the return to work activities for employees with suspected or confirmed Covid-19. RESUMO A pandemia da Covid-19 trouxe desafios ao sistema de saúde em diversas esferas: diagnóstico, tratamento e medidas para evitar a disseminação da doença. Com a maior disponibilização e variedades de testes diagnósticos, torna-se fundamental sua adequada interpretação. Este posicionamento pretende orientar unidades de diálise em relação ao uso de critérios clínicos e testes diagnósticos para a tomada de decisão referente à descontinuação do isolamento de pacientes com suspeita ou confirmação de Covid-19, assim como para o retorno às atividades laborais de colaboradores com suspeita ou confirmação de Covid-19.
