ABSTRACT
Objective:
To study the clinical and etiological characteristics of viral pneumonia in patients with chronic obstructive pulmonary disease(VP-COPD), and to identify the risk factors associated with poor prognosis.Methods:
From August 1, 2017 to August 1, 2019, totally 235 patients in a general hospital in Beijing were prospectively enrolled in this research, and all patients were diagnosed with viral pneumonia by imaging and etiology. The patients were divided into VP-COPD group(n=60) and VP-nCOPD(viral pneumonia in non-COPD patients) group(n=175). Pathogen detection and clinical characteristics were compared between the two groups.Finally, the binomial logistic regression was used to explore the risk factors associated with severe VP-COPD.Results:
Compared with the VP-nCOPD group, the VP-COPD group was older(76.5 vs 66.0 years, P=0.001), and the CURB-65 score(2 vs 1, P= 0.001) and the PSI score(111 vs 85, P<0.001) were higher at admission. Pseudomonas aeruginosa(χ²= 10.308, P= 0.001) and Staphylococcus aureus(χ²= 5.953, P=0.028) were the most common co-infection bacteria. In the VP-COPD group type â ¡ respiratory failure was more common(23.3% vs 6.8%, P<0.001), the number of severely ill patients was larger(48.3% vs 30.3%, P=0.011), the length of hospital stay was longer(13 vs 8, P<0.001), and the mortality rate during hospitalization was higher(18.3% vs 7.4%, P=0.016) in the VP-nCOPD group. Multivariate analysis showed that the level of blood glucose(OR 1.73, 95%CI 1.22-2.44, P= 0.002) and pleural effusion(OR 133.12, 95%CI 7.57-2 340.36, P=0.001) were risk factors for severe VP-COPD patients.Conclusion:
Viral pneumonia in patients with COPD tended to develop into severe cases and had a poor prognosis.
