【 摘 要 】

Background: Respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and human parainfluenza virus (hPIV) are paramyxoviruses (PMVs) that are important etiologies of community-acquired pneumonia. However, current knowledge about the clinical features and outcomes of PMV-related pneumonia (PMV-p) is limited. We aimed to investigate the clinical characteristics and disease severity in immunocompetent adults hospitalized with hMPV-related pneumonia (hMPV-p), hPIV-related pneumonia (hPIV-p), or RSV-related pneumonia (RSV-p). Methods: We retrospectively recruited 488 patients with PMV-p (153 with RSV-p, 137 with hMPV-p, and 198 with hPIV-p) from five teaching hospitals in China during 2011–2019. Univariate and multivariate analyses were performed to identify predictors to distinguish hMPV-p/hPIV-p from RSV-p and evaluate the effects of virus types on the clinical outcomes. Results: Compared with RSV-p, sputum production [ odds ratio ( OR ) 5.029, 95% confidence interval ( CI ) 2.452–10.312, P < 0.001] was positively associated with hMPV-p, while solid malignant tumor ( OR 0.346, 95% CI 0.126–0.945, P = 0.038), nasal congestion ( OR 0.102, 95% CI 0.041–0.251, P < 0.001), and respiratory rate ≥ 30 breaths/min ( OR 0.296, 95% CI 0.136–0.640, P = 0.002) were negatively related to hMPV-p. Sputum production ( OR 13.418, 95% CI 6.769–26.598, P < 0.001) was positively associated with hPIV-p, while nasal congestion ( OR 0.194, 95% CI 0.098–0.387, P < 0.001), dyspnea ( OR 0.469, 95% CI 0.272–0.809, P < 0.001), and respiratory rate ≥30 breaths/min ( OR 0.090, 95% CI 0.032–0.257, P < 0.001) on admission were negatively related to hPIV-p. After adjustment for confounders, multivariate logistic regression analysis suggested that hMPV-p ( OR 0.355, 95% CI 0.135–0.932, P = 0.035) and hPIV-p ( OR 0.311, 95% CI 0.121–0.784, P = 0.013) were associated with decreased 30-day mortality compared with RSV-p. RSV infection ( OR 4.183, 95% CI 1.709–10.236, P = 0.002) was identified as an independent predictor of 30-day mortality in patients with PMV-p. Conclusion: RSV-p caused more severe disease than hMPV-p and hPIV-p. Although some clinical features are helpful for distinguishing the diseases, etiologic diagnosis is critical in the management of the PMV-p.
