Asthma in the elderly and COVID-19: results of the 90-day post-hospital follow-up.

Background. After the first wave of the new SARS-CoV-2 coronavirus infection, the researchers focused on identifying potential short-and long-term complications of COVID-19, especially in high-risk patients, after prolonged hospitalization and intensive care. Objective. To study the outcomes, adverse effects of severe COVID-19 and their predictors 90 days after hospital discharge in elderly patients with asthma. Material and methods. The study included elderly patients (101 subjects, 42 males and 59 females;median age 74 (67;79) years) with asthma, discharged from the hospital after treatment of severe COVID-19. They were followed up for 90 days after discharge. In the hospital, COVID-19 was confirmed by laboratory tests (polymerase chain reaction method) and/or clinically and radiologically. All patients had a documented history of asthma according to GINA 2020 criteria. Results and discussion. During the 90-day post-hospital follow-up, 86 (85%) patients survived, and 15 (15%) died after discharge. Deaths were reported within 1 to 4 weeks after discharge: 6 subjects died during re-hospitalization, 6 at home, and 3 in a rehabilitation center. The multivariate regression analysis model, adjusted for all statistically significant indicators, and the ROC analysis showed the most significant predictors of 90-day post-hospital mortality and their threshold values. They include the Charlson comorbidity index >=4 points, lung damage according to computed tomography >=30%, the absolute number of eosinophils <=100 cells/muL, and concomitant diabetes mellitus. The analysis showed that 90-day post-hospital mortality depends on combinations of identified risk factors;a combination of two, three, and especially four risk factors statistically significantly is associated with patients' lower average survival time. Conclusion. The key risk factors for 90-day post-hospital mortality in elderly patients with asthma after severe COVID-19 include the Charlson comorbidity index, lung damage >=30% according to computed tomography, the absolute number of eosinophils <=100 cells/muL, and concomitant diabetes mellitus. The 90-day post-hospital survival rate is correlated with the number of risk factors identified in patients. The effect of asthma severity on 90-day post-hospital mortality in elderly patients was not observed.Copyright © 2023, Media Sphera Publishing Group. All rights reserved.

[Risk factors for adverse outcomes in elderly patients with asthma and severe COVID-19 at the hospital and early post-hospital stages].

BACKGROUND: Mortality and COVID-19 related factors are thoroughly analyzed. Given the large number of hospitalized patients, the potential short- and long-term COVID-19 related complications, further research is needed on the possible consequences of hospitalization, especially in higher-risk patients, after prolonged hospitalization and intensive care admission. AIM: To study the clinical course and outcomes of severe COVID-19 in elderly patients with asthma at the hospital and early post-hospital stages. MATERIALS AND METHODS: The study included 131 elderly patients (WHO, 2020) >60 years old, n=131 with asthma, hospitalized for severe COVID-19. Of these, 86 (65.6%) patients survived, 30 (22.9%) died in the hospital, and 15 (14.9%) patients died after discharge from the hospital (in the 90-day post-hospital period). COVID-19 was confirmed by laboratory tests (SARS-CoV-2 PCR RNA test) and/or clinically and radiologically. All patients had a documented history of asthma. Patients were followed up during the hospital stay and for 90 days after discharge. RESULTS: Comparison of outcomes showed that in the groups of patients with a fatal outcome (regardless of the stage), the Charlson comorbidity index, respiratory rate, extent of lung damage assessed by computed tomography, the absolute leukocyte and neutrophil number and the ratio of neutrophils to lymphocytes were statistically significantly higher. The absolute number of eosinophils was lower in these groups. In the group of patients who died during hospitalization, severe (IV-V) asthma (p=0.03), steroid use during the previous year (p=0.02), chronic heart failure with a reduced ejection fraction (p=0.009) were more common, and atopic asthma phenotype was less common (p=0.02). In those who died after discharge, more common were non-invasive ventilation and diabetes mellitus (p<0.001). The multivariate regression analysis model revealed the most significant predictors of mortality at the hospital and early post-hospital stages. CONCLUSION: Adverse outcomes of severe COVID-19 in elderly patients with asthma include hospital and post-hospital mortality. The most significant predictors of mortality are the comorbidity index and low eosinophil count. Hospital mortality is associated with a higher ratio of neutrophils to lymphocytes and lower total protein levels; early (90-day) post-hospital mortality is associated with extensive lung damage shown by computed tomography and diabetes mellitus.

Analysis of severity and evaluation of prognosis in elderly patients with bronchial asthma and severe COVID-19

Introduction. The role of comorbid conditions in susceptibility to SARS-CoV-2 infection and the severity of associated COVID-19 disease has been an area of ongoing research since the pandemic began. Objective. To evaluate the impact of elderly asthma on the clinical course and outcomes of severe COVID-19. Materials and methods. Elderly patients (WHO, 2020) (> 60 years, n = 131) with bronchial asthma (BA) hospitalized for severe COVID-19 were included in the study. The presence of COVID-19 was confirmed by laboratory tests (PCR smear) and/or clinical and radiological examinations. All patients had a history of a confirmed diagnosis of bronchial asthma (GINA, 2020). Follow-up was performed at the hospital stage and for 90 days after discharge from the hospital. Results. In the groups of patients with lethal outcome (regardless of the stage) there were statistically significantly higher Charlson index, respiratory rate, CT lung lesion volume, leukocyte, neutrophil and neutrophil to lymphocyte ratios, lower absolute eosinophil count. In the group of patients who died during hospitalization, severe (IV–V) asthma (p = 0.03), steroid use during the previous year (p = 0.02), chronic heart failure (p = 0.009), and the atopic asthma phenotype was less common (p = 0.02). Those who died in the 90-day posthospital period had greater lung lesion volume on CT scan, and diabetes mellitus was more common (p < 0.001). The most significant predictors of mortality were identified. Conclusion. The common most significant predictors of hospital and 90-day posthospital mortality in older patients with bronchial asthma were comorbidity index and lower eosinophil levels. Hospital mortality is further characterized by a higher neutrophil to lymphocyte ratio and lower total protein;90-day posthospital mortality by the amount of lung damage on CT scan and the presence of diabetes mellitus. © 2022, Remedium Group Ltd.
