Prognostic factors in hospitalized patients diagnosed with SARS-CoV-2 infection, Bogotá, Colombia
Abstract
Introduction: Infection with the new SARS-Cov-2 coronavirus is a worldwide public health emergency; its diagnosis is based on molecular tests, while its prognosis depends on the patient’s history and on some paraclinical tests. In Colombia, forecasts are not yet counted. Objective: To assess the factors associated with the development of severe disease in hospitalized patients diagnosed with SARS-CoV-2 infection, as well as the prognostic factors for the outcome of mortality. Materials and methods: We conducted an ambispective cohort study in hospitalized patients at the Fundación Cadioinfantil from March to June, 2020. Results: Of the 104 patients analyzed, 31.7% (n=33) had a severe presentation and 9.6% (n=10) had a mortality outcome. For mortality, the most important prognostic factor was the development of severe disease followed by age over 60 years and malnutrition. For the development of the severe disease, prognostic factors were a history of hemodialysis (HR=135), diabetes (HR=4.4), and an increased level of lactate dehydrogenase (LDH) (HR=1,004), while the lymphocyte count over 1,064 was a protective factor (HR=0.9). In the classification of patients, the National Early Warning Score (NEWS2) score in the high and low-risk categories corresponded to the best performance. There was no difference between the treatments administered. Conclusions: The most important prognostic factors for mortality were being over 60 years of age, hypertension, diabetes, and cirrhosis, while for the development of severe disease they were chronic kidney disease with hemodialysis, NEWS2 with high risk at admission, increased levels of LDH and C reactive protein (CRP), and leukocytosis.
Introducción. La infección por el nuevo coronavirus SARS-Cov-2 es una emergencia de salud pública en todo el mundo; su diagnóstico se basa en pruebas moleculares, en tanto que su pronóstico depende de los antecedentes del paciente y de algunos exámenes paraclínicos. En Colombia aún no se cuenta con datos de pronóstico en una población local. Objetivo. Evaluar los factores asociados con el desarrollo de la enfermedad grave en pacientes hospitalizados con diagnóstico de infección por SARS-CoV-2, así como los factores pronósticos de la mortalidad. Materiales y métodos. Se hizo un estudio de cohorte ambispectivo en pacientes hospitalizados en la Fundación Cardioinfantil entre marzo y junio de 2020. Resultados. De los 104 pacientes analizados, en el 31,7 % (n=33) la infección fue grave y en el 9,6 % (n=10) se produjo la muerte. El factor pronóstico más importante de la mortalidad fue el desarrollo de la enfermedad grave, seguido de una edad de más de 60 años y la desnutrición. Para el desarrollo de la enfermedad grave los factores pronósticos fueron los antecedentes de hemodiálisis (hazard ratio, HR=135), diabetes (HR=4,4) y el aumento en el nivel de la lactato deshidrogenasa (LDH) (HR=1,004), en tanto que un conteo de linfocitos superior a 1.064 fue un factor protector (HR=0,9). El puntaje del National Early Warning Score (NEWS2) correspondiente a las categorías de alto y bajo riesgo fue el que mejor rendimiento tuvo. No hubo diferencia entre los tratamientos administrados. Conclusiones. Los factores pronósticos más importantes para la mortalidad fueron tener más de 60 años, hipertensión, diabetes y cirrosis, en tanto que para el desarrollo de la enfermedad grave fueron la enfermedad renal crónica con hemodiálisis, un puntaje de NEWS2 de alto riesgo al ingreso, y aumento en los niveles de LDH y proteína C reactiva, y leucocitosis.
