Clinical features and progression of acute respiratory distress syndrome in coronavirus disease 2019
Abstract
Background
The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in a cluster of coronavirus disease 2019 (COVID-19). We reported the clinical characteristics of COVID-19 patients with acute respiratory distress syndrome (ARDS), and further investigated the treatment and progression of ARDS in COVID-19.
Methods
This study enrolled 109 patients with COVID-19 admitted to the Central Hospital of Wuhan, a designated hospital in Wuhan, China, from January 2 to February 1, 2020. Patients were followed up to February 12, 2020. The clinical data were collected from the electronic medical records. The differences in the treatment and progression with the time and the severity of ARDS were determined.
Findings
Among 109 patients, mean age was 55 years, and 59 patients were male. With a median 15 days (range, 4 to 30 days) follow-up period, 31 patients (28.4%) died, while 78 (71.6%) survived and discharged. Of all patients, 53 (48.6%) developed ARDS. Compared to non-ARDS patients, ARDS patients were elder (mean age, 61 years vs. 49 years), and more likely to have the coexistent conditions, including diabetes (20.8% vs. 1.8%), cerebrovascular disease (11.3% vs. 0%), and chronic kidney disease (15.1% vs. 3.6%). Compared to mild ARDS patients, those with moderate and severe ARDS had higher mortality rates. No significant effect of antivirus, glucocorticoid, or immunoglobulin treatment on survival was observed in patients with ARDS.
Interpretation
The mortality rate increased with the severity of ARDS in COVID-19, and the effects of current therapies on the survival for these patients were not satisfactory, which needs more attention from clinicians.
