Health of the Newborn and Breastfeeding during the COVID-19 Pandemic: A Literature Review

Abstract

Objective The present article presents a literature review concerning the microbiota of breast milk and the influence of epigenetics in the susceptibility to COVID-19.

Methods A literature review.

Results Breastfeeding transfers microbiota, nutrients, diverse white blood cells, prebiotics, hormones, and antibodies to the baby, which provide short- and long-term immunological protection against several infectious, gastrointestinal, and respiratory illnesses. The little evidence available shows that breast milk very rarely carries the SARS-CoV-2 virus, and even in those cases, it has been discarded as the source of contagion.

Conclusion The reviewed studies show evidence of a beneficial effect of breastfeeding and highlights its importance on the current pandemic due to the immune reinforcement that it provides. Breastfed individuals showed better clinical response due to the influence on the microbiota and to the nutritional and immune contribution provided by breast milk, compared with those who were not breastfed.

Resumo

Objetivo O presente artigo apresenta uma revisão de literatura sobre a microbiota do leite materno e a influência da epigenética na suscetibilidade à COVID-19.

Métodos Revisão de literatura.

Resultados A amamentação transfere microbiota, nutrientes, diversos glóbulos brancos, prebióticos, hormônios e anticorpos para o bebê, os quais proporcionam proteção imunológica de curto e longo prazo contra diversas doenças infecciosas, gastrointestinais e respiratórias. As poucas evidências disponíveis mostram que o leite materno transporta muito raramente o vírus SARS-CoV-2, e mesmo nestes casos, ele foi descartado como fonte de contágio.

Conclusão Os estudos revisados mostram evidências de um efeito benéfico da amamentação e destacam sua importância na atual pandemia devido ao reforço imunológico que ela proporciona. Os indivíduos amamentados mostraram melhor resposta clínica devido à influência sobre a microbiota, e à contribuição nutricional e imunológica proporcionada pelo leite materno, em comparação com aqueles que não o foram.
