Influence of influenza vaccine and comorbidity on the evolution of hospitalized COVID-19 patients. / Influencia de la vacunación antigripal y la comorbilidad en la evolución de los pacientes hospitalizados por COVID-19.

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.

Aprotinin treatment against SARS-CoV-2: A randomized phase III study to evaluate the safety and efficacy of a pan-protease inhibitor for moderate COVID-19.

BACKGROUND: SARS-CoV-2 virus requires host proteases to cleave its spike protein to bind to its ACE2 target through a two-step furin-mediated entry mechanism. Aprotinin is a broad-spectrum protease inhibitor that has been employed as antiviral drug for other human respiratory viruses. Also, it has important anti-inflammatory properties for inhibiting the innate immunity contact system. METHODS: This was a multicentre, double-blind, randomized trial performed in four Spanish hospitals comparing standard treatment versus standard treatment + aprotinin for patients with COVID-19 between 20 May 2020 and 20 October 2021. The primary efficacy outcomes were length of hospital stay and ICU admission. The secondary endpoints were each of the primary efficacy outcomes and a composite of oxygen therapy, analytical parameters and death. Safety outcomes included adverse reactions to treatment during a 30-day follow-up period. Treatment was given for 11 days or till discharge. RESULTS: With almost identical analytical profiles, significant differences were observed in treatment time, which was 2 days lower in the aprotinin group (p = .002), and length of hospital admission, which was 5 days shorter in the aprotinin group (p = .003). The incidence of discharge was 2.19 times higher (HR: 2.188 [1.182-4.047]) in the aprotinin group than in the placebo group (p = .013). In addition, the aprotinin-treated group required less oxygen therapy and had no adverse reactions or side effects. CONCLUSION: Inhaled aprotinin may improve standard treatment and clinical outcomes in hospitalized patients with COVID-19, resulting in a shorter treatment time and hospitalization compared with the placebo group. The administration of aprotinin was safe.

[Risk factors for mortality in patients over 65 years old hospitalized by COVID-19]. / Factores de riesgo de mortalidad en pacientes mayores de 65 años hospitalizados por COVID-19.

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.
