Identification of Predictive Markers of Response to Immunomodulators in the Treatment of COVID-19 Patients.

BACKGROUND: Proper identification of patients at risk of developing serious disease in the context of SARS-CoV-2 infection, as well as the initiation of early treatment, is one of the fundamental elements for successful management of COVID-19. The main objective of this study was to evaluate the usefulness of serum biomarkers (neutrophils, lymphocytes, C-reactive protein, lactate dehydrogenase, D-dimer, ferritin, and interleukin-6) to predict the early response to immunosuppressant therapy in COVID-19 patients. METHODS: This is a case-control study nested in a retrospective cohort, which included hospitalized patients with interstitial pneumonia and with elevation of some proinflammatory parameters. Each of the individuals who died during the 28-day follow-up was defined as a case. For each case, 4 controls were selected, matched by age, gender, and comorbidities. RESULTS: The initial cohort included 856 patients. The incidence of therapeutic failure in the cohort was 14%, thus we identified a total of 120 cases. After the application of a Cox regression model, high serum concentrations of LDH (> 451 IU/L), ferritin (> 1,014 ng/mL) and D-Dimer (> 1,300 ng/mL) were identified as predictors of poor response to treatment. Highly-specific cut-off points could not be established for any of these biomarkers. CONCLUSIONS: Some inflammatory biomarkers, such as LDH, ferritin, and D-dimer, may be helpful in identifying patients for whom an early immunomodulatory therapeutic intervention should be considered in the treatment of COVID-19 patients with pneumonia.

[Acute poisoning among patients attended to in an emergency department: From the pre-pandemic period to the new normality]. / Intoxicaciones agudas atendidas en un servicio de urgencias. De la prepandemia a la nueva normalidad.

Background: The COVID-19 pandemic has caused global changes that affect the daily life of the world's population, with a direct impact on individuals' physical and mental health as well as on their social and recreational habits. Methods: This study aimed to retrospectively analyze the demographic and clinical characteristics of patients attended to for acute poisoning in a hospital emergency department (ED) at three different periods of time: pre-pandemic (2019), after strict lockdown of the population in Spain (2020), and post-pandemic (2021). We analyzed 2 months (June and July) in each period. Results: A total of 1,182 cases of acute poisoning were included. Compared to the pre-pandemic period, during lockdown, the number of patients with acute poisoning decreased (2019: 1.9% vs. 2020: 1.5%; p<.01); the ratio of men to women increased (2.0 vs. 1.4; p=.02); and the mean age of patients increased (2019: 31.4 vs. 2020: 41.3; p<.001), a trend which continued in 2021 (38.3). Poisoning with suicidal intention also increased during the pandemic (2019: 8.71% vs. 2020: 21.0%; p<.01) whereas poisonings with a recreational intention declined (2019: 76.1% vs. 2020: 62.0%; p<.01) with a non-significant increase in 2021 (69.0%, p=.07). Conclusion: The COVID-19 pandemic generated clinical and epidemiological changes in the acute poisonings attended to in a hospital emergency department during the various phases of the pandemic.

Intoxicaciones agudas atendidas en un servicio de urgencias. De la prepandemia a la nueva normalidad / Acute poisoning among patients attended to in an emergency department: From the pre-pandemic period to the new normality

Fundamentos La pandemia por COVID-19 ha provocado cambios globales que afectan a la vida diaria de la población mundial, con un impacto directo sobre la salud física y mental de los individuos, así como en sus hábitos sociales y recreativos. Métodos Análisis retrospectivo de aspectos demográficos y clínicos de los pacientes atendidos por intoxicaciones agudas en un servicio de urgencias hospitalario durante 3 períodos distintos: prepandemia (2019), tras el confinamiento domiciliario (2020) y en el período pospandémico (2021), analizando en cada uno los meses de junio y julio. Resultados Se incluyeron 1.182 intoxicaciones agudas. En relación con la etapa prepandémica, el número de intoxicados disminuyó durante el confinamiento (2019: 1,9 vs. 2020: 1,5%; p<0,01), incrementándose la ratio varón/mujer (2,0 vs. 1,4; p=0,02) y la edad media (2019: 31,4 vs. 2020: 41,3; p<0,001), tendencia que se mantuvo en el año 2021 (38,3). La intoxicación con motivación suicida también aumentó en dicho período (2019: 8,71 vs. 2020: 21,0%; p<0,01), mientras que las lúdicas decrecieron (2019: 76,1 vs. 2020: 62,0%; p<0,01), con un aumento no significativo en el último año 2021 (69,0%; p=0,07). Conclusiones La pandemia por COVID-19 ha generado cambios clínicos y epidemiológicos en las intoxicaciones agudas atendidas en un servicio de urgencias hospitalario durante las distintas fases de la pandemia (AU)
