ABSTRACT

Resumen Introducción: Existen índices hematológicos que correlacionan la severidad y predicen la mortalidad, principalmente en estados sépticos y de inflamación. Objetivo: Correlacionar los índices neutrófilo/linfocito (INL), plaqueta/linfocito (IPL) e inmunidad/inflamación sistémica (IIIS) con la severidad de COVID-19. Método: Estudio descriptivo, analítico y retrospectivo de pacientes con neumonía por COVID-19, en quienes se analizaron INL, IPL e IIIS. Resultados: Se incluyeron 100 pacientes, 54 hombres y 46 mujeres, con una media de 49.4 ± 19.3 años. Las medias de INL, IPL e IIIS fueron 10.7 ± 10.9, 290.1 ± 229.2 y 2.6 ± 3.4 × 109, respectivamente. En 54 %, la neumonía fue leve y en 46 %, grave. En cuanto a los desenlaces hospitalarios, 75 % egresó por mejoría y 25 % falleció. Las medias de INL, IPL e IIIS de los pacientes que fallecieron versus las de los pacientes que mejoraron fueron 20.4 ± 16.9 versus 7.5 ± 4.9 (p = 0.001), 417.1 ± 379.7 versus 247.7 ± 127.4 (p = 0.038) y 4.8 ± 6.1 versus 1.9 ± 1.2 × 109 (p = 0.030), respectivamente. Conclusión: Los índices hematológicos en pacientes con neumonía por COVID-19 pueden ser empleados como predictores de severidad y pronóstico.


Abstract Introduction: There are hematological parameters that correlate severity and predict mortality mainly in septic and inflammatory states. Objective: To correlate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) with COVID-19 severity. Method: Descriptive, analytical, retrospective study of patients with COVID-19 pneumonia, in which NLR, PLR and SII were analyzed. Results: One-hundred patients were included, 54 men and 46 women, with a mean age of 49.4 ± 19.3 years. NLR, PLR and SII means were 10.7 ± 10.9, 290.1 ± 229.2, and 2.6 ± 3.4 × 109, respectively. In 54 %, pneumonia was mild, and in 46 %, severe. Regarding hospital outcomes, 75 % were discharged due to improvement and 25 % died. NLR, PLR and SII means of the patients who died versus the patients who improved were 20.4 ± 16.9 versus 7.5 ± 4.9 (p = 0.001), 417.1 ± 379.7 versus 247.7 ± 127.4 (p = 0.038) and 4.8 ± 6.1 versus 1.9 ± 1.2 × 109 (p = 0.030), respectively. Conclusion: Hematological parameters can be used in patients with COVID-19-associated pneumonia as predictors of severity and prognosis.
