ABSTRACT
Background:
The long-term prognosis of COVID-19 survivors remains poorly understood. It is evidenced that the lung is the main damaged organ in COVID-19 survivors, most notably in impairment of pulmonary diffusion function. Hence, we conducted a meta-analysis of the potential risk factors for impaired diffusing capacity for carbon monoxide (DLCO) in convalescent COVID-19 patients.Methods:
We performed a systematic search of PubMed, Web of Science, Embase, and Ovid databases for relevant studies from inception until January 7, 2022, limited to papers involving human subjects. Studies were reviewed for methodological quality. Fix-effects and random-effects models were used to pool results. Heterogeneity was assessed using I2. The publication bias was assessed using the Egger's test. PROSPERO registration CRD42021265377.Findings:
A total of eighteen qualified articles were identified and included in the systematic review, and twelve studies were included in the meta-analysis. Our results showed that female (OR 4.011; 95% CI 2.928-5.495), altered chest computerized tomography (CT) (OR 3.002; 95% CI 1.319-6.835), age (OR 1.018; 95% CI 1.007-1.030), higher D-dimer levels (OR 1.012; 95% CI 1.001-1.023) and urea nitrogen (OR 1.004;95% CI 1.002-1.007) were identified as risk factors for impaired DLCO.Interpretation:
Pulmonary diffusion capacity was the most common impaired lung function in recovered patients with COVID-19. Several risk factors, such as female, altered chest CT, older age, higher D-dimer levels and urea nitrogen are associated with impairment of DLCO. Raising awareness and implementing interventions for possible modifiable risk factors may be valuable for pulmonary rehabilitation.Funding:
