Abstract

Introducción: La sepsis neonatal es una causa frecuente de morbilidad y mortalidad infantil. Se le ha definido como un síndrome clínico caracterizado por signos sistémicos de infección, acompañado de bacteriemia en el primer mes de vida. Por lo tanto, el diagnóstico temprano es fundamental.

Objetivo: Conocer la sensibilidad y especificidad de la combinación de biomarcadores séricos como procalcitonina, proteína C reactiva y volumen plaquetario medio en el diagnóstico temprano de sepsis neonatal.

Material y métodos: Estudio clínico, de tipo prospectivo, predictivo, observacional, analítico, longitudinal y conveniencia. Se analizaron los biomarcadores como PCT, PCR, VPM para diagnosticar sepsis neonatal. Se incluyeron todos los recién nacidos con factores de riesgo a cada uno de ellos se le tomó 4 muestras seriadas. El análisis estadístico se realizó en la base de datos SPSS versión 25.

Resultados: Se estudió a 146 recién nacidos y se detectó en los 3 biomarcadores séricos (PCT, PCR, VPM) entre las 48 a 72 horas una sensibilidad del 80%, una especificidad del 79%, un VPP del 49%, VPN del 93%. y un índice J (Youden) de 0,58. Y encontramos en el SRIS una sensibilidad de 87.23%, especificidad 91.92%, VPP 83.67%, VPN 93.8%, LHR (+) 10.8, LHR (-) 0.14 y un índice J de 0.78.

Conclusión: La combinación de biomarcadores para el diagnóstico de sepsis (PCT, PCR y VPM) en el recién nacido se considera como buena entre las 48 y 72 horas de inicio del proceso infeccioso.

Introduction: Neonatal sepsis is a frequent cause of infant morbidity and mortality. It has been defined as a clinical syndrome characterized by systemic signs of infection, accompanied by bacteremia in the first month of life. Therefore, early diagnosis is essential.

Objective: To determine the sensitivity and specificity of the combination of serum biomarkers such as procalcitonin, C-reactive protein and mean platelet volume in the early diagnosis of neonatal sepsis. Material and methods: A prospective, predictive, observational, analytical, longitudinal, convenience clinical study was conducted. Biomarkers such as PCT, CRP, and MPV were analyzed to diagnose neonatal sepsis. All newborns with risk factors were included and 4 serial samples were taken from each of them. Statistical analysis was performed in the SPSS version 25 database.

Results: A total of 146 newborns were studied and a sensitivity of 80%, a specificity of 79%, a PPV of 49%, a NPV of 93%, and a J (Youden) index of 0.58 were detected in the 3 serum biomarkers (PCT, CRP, MPV) between 48 and 72 hours. And we found in the SIRS a sensitivity of 87.23%, specificity of 91.92%, PPV of 83.67%, NPV of 93.8%, LHR (+) 10.8, LHR (-) 0.14 and a J index of 0.78.

Conclusion: The combination of biomarkers for the diagnosis of sepsis (PCT, CRP and MPV) in the newborn is considered good between 48 and 72 hours after the onset of the infectious process.
