Zusammenfassung: | Introduction: Neonatal sepsis (NS) is an important cause of morbidity and mortality in newborns despite advances. Possessing a complex pathophysiology, NS presents different clinical forms and eventually scarce guiding symptoms or signs, which makes diagnosis, severity analysis and timely therapy difficult. Objective: To analyze the use of biomarkers for the early diagnosis and prognostic evaluation of SN. Method: Literature review with search in PubMed/MEDLINE, Scielo and VHL databases, conducted between February and March 2021, with analysis of 21 articles published from January 2010 to December 2020. Results and Discussion: The biomarkers used in SN analysis, such as C-reactive protein (CRP), procalcitonin (PCT), interleukins (IL-6, IL-8), tumor necrosis factor alpha (TNF-[alpha]) and cell surface markers are important for faster diagnosis and assistance, enabling better prognosis for neonatal cases. Conclusion: The study of biomarkers with the knowledge of their serum levels during disease progression can facilitate the analysis and predict the severity of SN, besides following the establishment of an early protocol, increasing the proportion of patients who receive an effective treatment and obtain better prognosis. Keywords: Neonatal sepsis; Biomarkers; Newborn. Introducao: A sepse neonatal (SN) e importante causa de morbimortalidade em recem-nascidos apesar dos avancos. Possuindo uma fisiopatologia complexa, a SN apresenta diferentes formas clinicas e, eventualmente, sintomas ou sinais norteadores escassos; o que dificulta o diagnostico, a analise da gravidade e a terapeutica oportuna. Objetivo: Analisar o uso de biomarcadores para o diagnostico precoce e avaliacao prognostica da SN. Metodo: Revisao bibliografica com busca nas bases de dados PubMed/MEDLINE, Scielo e BVS, realizada entre fevereiro e marco de 2021, com analise de 21 artigos publicados de janeiro de 2010 a dezembro de 2020. Resultados e Discussdo: Os biomarcadores usados na analise da SN, como a proteina C reativa (PCR), procalcitonina (PCT), interleucinas (IL-6, IL-8), fator de necrose tumoral alfa (TNF-[alpha]) e marcadores de superficie celular, sao importantes no diagnostico e assistencia mais celeres, viabilizando um melhor prognostico para os casos neonatais. Conclusao: O estudo dos biomarcadores com o conhecimento acerca da modificacao de seus niveis sericos durante a progressao da doenca pode facilitar a analise e predizer a gravidade da SN, alem de orientar a instauracao de um |
