Insights
This study of fatal COVID-19 cases found that older males with chronic diseases were most affected. Eosinophilopenia indicated a poor prognosis, and combined antimicrobial drugs showed limited benefit.
Area of Science:
- Infectious Diseases
- Epidemiology
- Critical Care Medicine
Background:
- Coronavirus disease (COVID-19) caused over 286,000 global deaths by May 2020.
- Risk factors for COVID-19 mortality, such as advanced age and comorbidities, require precise definition.
Purpose of the Study:
- To detail the clinical characteristics of 85 fatal COVID-19 cases.
- To identify key clinical features and outcomes in a cohort of deceased COVID-19 patients.
Main Methods:
- Retrospective analysis of medical records from 85 fatal COVID-19 cases (January 9–February 15, 2020).
- Data collected included demographics, medical history, comorbidities, symptoms, laboratory findings, imaging, and treatments.
Main Results:
- The median age of deceased patients was 65.8 years, with 72.9% being male.
- Common symptoms included fever, shortness of breath, and fatigue. Hypertension and diabetes were prevalent comorbidities.
- Eosinophil counts were very low in 81.2% of patients. Respiratory failure, shock, and acute respiratory distress syndrome were frequent complications.
Conclusions:
- Fatal COVID-19 cases predominantly involved males over 50 with chronic noncommunicable diseases.
- Multiple organ failure was the primary cause of death. Early shortness of breath may signal exacerbation, and eosinophilopenia suggests a poor prognosis.
- Combination antimicrobial therapy did not significantly improve outcomes in this patient group.
Abstract:
Rationale: The global death toll from coronavirus disease (COVID-19) virus as of May 12, 2020, exceeds 286,000. The risk factors for death were attributed to advanced age and comorbidities but have not been accurately defined.Objectives: To report the clinical features of 85 fatal cases of COVID-19 in two hospitals in Wuhan.Methods: Medical records were collected of 85 fatal cases of COVID-19 between January 9, 2020, and February 15, 2020. Information recorded included medical history, exposure history, comorbidities, symptoms, signs, laboratory findings, computed tomographic scans, and clinical management.Measurements and Main Results: The median age of the patients was 65.8 years, and 72.9% were male. Common symptoms were fever (78 [91.8%]), shortness of breath (50 [58.8%]), fatigue (50 [58.8%]), and dyspnea (60 [70.6%]). Hypertension, diabetes, and coronary heart disease were the most common comorbidities. Notably, 81.2% of patients had very low eosinophil counts on admission. Complications included respiratory failure (80 [94.1%]), shock (69 [81.2%]), acute respiratory distress syndrome (63 [74.1%]), and arrhythmia (51 [60%]), among others. Most patients received antibiotic (77 [90.6%]), antiviral (78 [91.8%]), and glucocorticoid (65 [76.5%]) treatments. A total of 38 (44.7%) and 33 (38.8%) patients received intravenous immunoglobulin and IFN-α2b, respectively.Conclusions: In this depictive study of 85 fatal cases of COVID-19, most cases were males aged over 50 years with noncommunicable chronic diseases. The majority of the patients died of multiple organ failure. Early onset of shortness of breath may be used as an observational symptom for COVID-19 exacerbations. Eosinophilopenia may indicate a poor prognosis. A combination of antimicrobial drugs did not offer considerable benefit to the outcome of this group of patients.
