Insights
Pleural effusion in Coronavirus Disease 19 (COVID-19) patients indicates severe illness, increased mortality, and longer recovery times. This finding highlights the need for special attention to these patients for better outcomes.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Coronavirus Disease 19 (COVID-19) rapidly emerged as a global pandemic.
- Understanding clinical manifestations in specific patient groups is crucial.
Purpose of the Study:
- To investigate the clinical characteristics and outcomes of COVID-19 patients with pleural effusion.
- To determine if pleural effusion is a prognostic indicator in COVID-19.
Main Methods:
- Retrospective enrollment of COVID-19 patients from Union Hospital.
- Classification into groups based on computed tomography (CT) scan findings of pleural effusion.
- Comparison of clinical features, laboratory results, imaging, and outcomes between groups.
Main Results:
- Pleural effusion was present in 9.19% of COVID-19 patients.
- Patients with pleural effusion exhibited more severe or critical illness and higher mortality.
- Longer hospital stays, prolonged viral shedding, and delayed lung inflammation resolution were observed in patients with pleural effusion.
Conclusions:
- Pleural effusion in COVID-19 patients is associated with poor prognosis.
- These patients require specialized clinical attention.
- Pleural effusion may serve as a significant indicator of adverse outcomes in COVID-19.
Background:
Coronavirus Disease 19 (COVID-19) is a global health concern that has become a pandemic over the past few months. This study aims at understanding the clinical manifestations of COVID-19 patients with pleural effusion.
Methods:
COVID-19 patients were retrospectively enrolled from the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology. Pharyngeal swabs from patients were tested using real-time polymerase chain reaction. Patients with COVID-19 were divided into two groups based on their computed tomography (CT) scans for the presence of pleural effusion at admission. We compared the clinical features, laboratory findings, scans and clinical outcomes between the two groups.
Results:
Pleural effusion was observed in 9.19% of the patients. Patients with pleural effusion were more likely to be severe or critical cases. Moreover, patients with pleural effusion were associated with increased mortality. Of the 799 discharged patients, patients with pleural effusion had longer hospital stays and duration of viral shedding since the onset of symptoms as compared with that for patients without pleural effusion. After discharge, 217 patients visited for a follow-up CT re-examination at the Union Hospital. The CT scans showed that patients with pleural effusion required a longer time to resolve the lung inflammation after the onset of COVID-19 as compared with the time required by patients without pleural effusion.
Conclusion:
This population of patients requires special attention and pleural effusion may be an indicator of poor prognosis in COVID-19 patients.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
