ABSTRACT

OBJECTIVE: We aimed to test the association between acute kidney injury (AKI) and mortality in critically ill patients with Coronavirus disease 2019 (COVID-19). METHOD: We conducted a single-center case-control study at the intensive care unit (ICU) of a second-level hospital in Mexico. We included 100 patients with critical COVID-19 from January to December 2021, and collected demographic characteristics, comorbidities, APACHE II, SOFA, NEWS2, and CO-RADS scores at admission, incidence of intrahospital complications, length of hospital and ICU stay, and duration of mechanical ventilation, among others. RESULTS: The median survival of deceased patients was 20 days. After multivariable logistic regression, the following variables were significantly associated to mortality: AKI (adjusted odds ratio [AOR] 6.64, 95% confidence intervals [CI] = 2.1-20.6, p = 0.001), age > 55 years (AOR 5.3, 95% CI = 1.5-18.1, p = 0.007), and arrhythmias (AOR 5.15, 95% CI = 1.3-19.2, p = 0.015). Median survival was shorter in patients with AKI (15 vs. 22 days, p = 0.043), as well as in patients with overweight/obesity (15 vs. 25 days, p = 0.026). CONCLUSION: Our findings show that the development of AKI was the main risk factor associated with mortality in critical COVID-19 patients, while other factors such as older age and cardiac arrhythmias were also associated with this outcome. The management of patients with COVID-19 should include renal function screening and staging on admission to the Emergency Department.


OBJETIVO: Probar la asociación entre lesión renal aguda y mortalidad en pacientes con COVID-19 grave. MÉTODO: Realizamos un estudio de casos y controles unicéntrico en la unidad de cuidados intensivos (UCI) de un hospital de segundo nivel en México. Incluimos 100 pacientes con COVID-19 grave de enero a diciembre 2021, recolectando características demográficas, comorbilidad, APACHE II, SOFA, NEWS2 y CO-RADS al ingreso, incidencia de complicaciones intrahospitalarias, duración de la estancia hospitalaria y en la UCI, duración de ventilación mecánica, etc. RESULTADOS: La mediana de supervivencia de los pacientes que fallecieron fue de 20 días. Al realizar el análisis de regresión logística multivariable, las siguientes variables se asociaron significativamente con la mortalidad: lesión renal aguda (odds ratio ajustada [ORa]: 6.64; intervalo de confianza del 95% [IC95%]: 2.1-20.6; p = 0.001), edad > 55 años (ORa: 5.3; IC95%: 1.5-18.1; p = 0.007) y arritmias (ORa: 5.15; IC95%: 1.3-19.2; p = 0.015). La supervivencia fue menor en pacientes con lesión renal aguda (15 vs. 22 días; p = 0,043), así como en pacientes con sobrepeso u obesidad (15 vs. 25 días; p = 0.026). CONCLUSIONES: Nuestros resultados muestran que el desarrollo de lesión renal aguda es el principal factor de riesgo asociado a mortalidad en pacientes con COVID-19 grave, mientras que otros factores, como la edad > 55 años y la presencia de arritmias cardiacas, también se asocian a mortalidad por COVID-19. El manejo de pacientes con COVID-19 debe incluir el tamizaje y la estadificación de la función renal al ingreso a urgencias.
