ABSTRACT
BACKGROUND AND OBJECTIVE: The COVID-19 coronavirus disease outbreak is evolving around the world. The aim of this study is to evaluate the association between influenza vaccination and the risk of mortality in hospitalized COVID-19 patients, as well as other risk factors. MATERIALS AND METHODS: Retrospective observational study. This study was conducted among hospitalized patients with COVID-19 at Hospital La Mancha Centro between March 5 and 25, 2020. Information on influenza vaccination was extracted from electronic medical records. We used a multivariate logistic regression to explore the association between influenza vaccination and mortality from COVID and other risk factors. RESULTS: 410 patients were included. Influenza vaccine had no effect among COVID-19 hospitalized patients [OR: 1.55 (95%CI: 0.96 - 2.48; p=0.071)]. Increasing hospital mortality was associated with older age [OR: 1.05 (95% CI 1.02-1.07), per year increase; p<0.001)], Charlson ≥3 [OR: 1.84 (95%CI: 1.07-3.15, p=0.027)] and heart failure on admission [OR: 6 (IC95%: 1.6 - 21.7; p=0.007)] CONCLUSIONS: Influenza vaccine had no effect among COVID-19 hospitalized patients. The risk factors identified were older age, higher comorbidity and heart failure on admission.

Antecedentes y objetivo: El brote de la enfermedad COVID-19 está evolucionando en todo el mundo. Objetivo: Evaluar la asociación de la vacunación antigripal y otros factores y el riesgo de mortalidad en pacientes con COVID-19 hospitalizados. Materiales y métodos: Estudio observacional retrospectivo. Se realizó entre pacientes hospitalizados con COVID-19 del Hospital La Mancha Centro entre el 5 y el 25 de marzo de 2020. Utilizamos una regresión logística multivariable para explorar la asociación entre la vacunación antigripal y la mortalidad por COVID y otros factores de riesgo. Resultados: Se incluyeron 410 pacientes. La vacunación antigripal no tuvo efecto entre los pacientes hospitalizados por COVID-19 [OR: 1,55 (IC95%: 0,962,48; p = 0,071)]. El aumento de la mortalidad intrahospitalaria se asoció con edad avanzada [OR: 1,05, (IC95%: 1,021,07), por cada aumento de año; p < 0.001)], Charlson ≥ 3 [OR: 1,84 (IC95%: 1,073,15, p = 0,027)] e insuficiencia cardíaca al ingreso [OR: 6 (IC95%: 1,621,7; p = 0,007)]. Conclusiones: La vacuna antigripal no tuvo efecto en la evolución de pacientes hospitalizados por COVID-19. Los factores de riesgo identificados fueron la edad avanzada, mayor comorbilidad e insuficiencia cardíaca al ingreso.

ABSTRACT
BACKGROUND AND OBJECTIVE: COVID-19 is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has caused a global pandemic that we are currently suffering from. OBJECTIVE: to identify factors associated with the death of patients aged 65 years or older hospitalized for COVID-19. MATERIALS AND METHODS: Retrospective cohort study. We included patients aged 65 years or older who were hospitalized for COVID-19 and dead o discharged between March 5 and 25, 2020. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. RESULTS: 277 patients were included in this study. The bivariate analysis showed significant differences (p<0.05) between survivors and non survivors: age, increased dependence and comorbidity, history of ischemic heart disease, renal failure and non-hematological neoplasms, heart failure during admission, leukocytosis, elevated creatinine, PCR, GOT and troponin Ic values, lymphopenia, and decreased blood pH and SatO2. Multivariate logistic regression revealed that age ≥65 years (OR: 4.23 (95% CI: 1.43-12.52; p=0.009), lymphopenia <1000/µL (OR: 2.36 (95% CI: 1.07-5.20; p=0.033), creatinine>1.2mg/dL (OR: 3.08 (95% CI: 1.37-6.92; p=0.006), SatO2 <90% (OR: 2.29 (95% CI: 1.01-5.21; p=0.049) and troponin Ic>11ng/mL (OR: 2.32 (95% CI: 1.04-5.16; p=0.040) were independently associated with higher hospital mortality. CONCLUSIONS: Older age, lymphopenia, SatO2 <90%, elevated creatinine and troponin Ic values were independently associated with higher mortality in hospitalized patients with COVID-19, these factors could help clinicians to identify patients with poor prognosis.
