ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is the cause of the coronavirus disease 2019 (COVID-19) pandemic, which has a high case fatality rate. Most severely ill patients develop a special type of coagulopathy that had not been described before and that is now considered the main cause of death. For this reason, anticoagulant treatment has become one of the cornerstones of the treatment of this infection. However, the rate at which the evidence regarding the use of anticoagulants is generated is quite fast, and sometimes it is difficult to interpret and conflicting. After having performed an extensive review of the published literature, this proposal for the use of anticoagulant treatment is made, taking into account available resources in Mexico.


La infección por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) es la causante de la pandemia de enfermedad por coronavirus 2019 (COVID-19), con un índice de letalidad alto. La mayoría de los pacientes graves desarrollan un tipo especial de coagulopatía no descrito hasta ahora y la cual se considera ahora la principal causa de muerte. Por esta razón, el tratamiento anticoagulante se ha convertido en una de las piedras angulares del tratamiento de esta infección. Sin embargo, la velocidad con la que se genera la evidencia respecto al uso de anticoagulantes es muy rápida y, en ocasiones difícil de interpretar y contradictoria. Luego de hacer una revisión extensa de la literatura publicada, se hace esta propuesta para el uso del tratamiento anticoagulante tomando en cuenta los recursos disponibles en México.

ABSTRACT

INTRODUCTION: Various biomarkers based on blood counts have been useful for the prognosis of patients critically ill with COVID-19. OBJECTIVE: To describe the usefulness of the neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR) and lymphocyte-to-platelet (LPR) ratios for the prognosis of mortality and ventilatory support requirement for COVID-19. METHOD: Retrospective cohort of clinical records of patients with COVID-19 who required hospital care. RESULTS: One-hundred and -twenty-five cases were analyzed; mean age was 51 years, and 60 % were of the male gender; 21.6 % had type 2 diabetes mellitus, and 18.4 % had hypertension. Mean leukocyte count was 9.5 x 103/µL, with a neutrophil mean of 8.0 x 103/µL. Mean NLR was 12.01, while for MLR it was 0.442, and for LPR, 373.07. Regarding the area under the curve, the following values were recorded for mortality: 0.594 for NLR, 0.628 for MLR and 0.505 for LPR; as for mechanical ventilation, the values were 0.581 for NLR, 0.619 for MLR and 0.547 for LPR. In the univariate analysis, an NLR value > 13 (OR: 2.750, p = 0.001) and an MLR of > 0.5 (OR: 2.069, p = 0.047) were associated with mortality; LPR showed no impact on mortality or respiratory support. CONCLUSION: NLR and MLR are useful for predicting mortality in patients with COVID-19.


INTRODUCCIÓN: Diversos biomarcadores basados en conteos sanguíneos han sido de utilidad para el pronóstico de los pacientes en estado crítico por COVID-19. OBJETIVO: Describir la utilidad de los índices neutrófilo/linfocito (INL), monocito/linfocito (IML) y linfocito/plaqueta (IPL) para el pronóstico de la mortalidad y necesidad de soporte ventilatorio por COVID-19. MÉTODO: Cohorte retrospectiva de registros clínicos de pacientes con COVID-19 que requirieron atención hospitalaria. RESULTADOS: Se analizaron 125 casos, la edad media fue de 51 años y 60 %, del sexo masculino; 21.6 % padecía diabetes mellitus tipo 2 y 18.4 %, hipertensión. La media de leucocitos fue 9.5 × 103/µL y la de neutrófilos, de 8.0 × 103/µL. La media del INL fue de 12.01; del IML, de 0.442 y del IPL, de 373.07. Respecto al área bajo la curva se registraron los siguientes valores en cuanto a mortalidad: INL, 0.594; IML, 0.628 e ILP, 0.505; en cuanto a ventilación mecánica: INL, 0.581; IML, 0.619 e ILP, 0.547. En el análisis univariado, INL > 13 (RM = 2.750, p = 0.001) e IML > 0.5 (RM = 2.069, p = 0.047) se asociaron a mortalidad; ILP no mostró impacto en la mortalidad ni en el soporte respiratorio. CONCLUSIÓN: INL e IML son de utilidad para predecir la mortalidad en pacientes con COVID-19.
