Recent years have witnessed a yearly increase in the prevalence of COPD. OBJECTIVE: To investigate the impact of respiratory virus infections on patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and to perform sequencing typing and mutation analysis of viruses with high detection rate. METHODS: A total of 1523 inpatients with AECOPD admitted to our hospital from April 1,2020 to March 30,2022 were collected and divided into two groups: the infected group (n= 532) and the non-infected group (n= 991). The related indexes between the two groups were collected and compared (including clinical characteristics and laboratory tests that blood cell count, PCT, CRP, adenovirus, respiratory syncytial virus, rhinovirus, influenza A virus, influenza B virus, etc.). RESULTS: In the infected group, the proportion of patients with palpitations (49.44% VS 8.07%, P&lt; 0.001), lipid metabolism abnormalities (18.42% VS 39.96%, P&lt; 0.001), heart failure (39.85% VS 29.87%, P&lt; 0.001), disease duration (17.48 \u00b1 7.47 VS 12.45 \u00b1 11.43 d, P&lt; 0.001), and poor prognosis (69.55% VS 17.15%, P&lt; 0.001) were higher than those in the non-infected group; Adenovirus (ADV) accounted for 75.94% (404\/532) of all infected viruses. 31 virus strains could be categorized into 16 ADV-C1, one ADV-C5, two ADV-B3, three ADV-B7, two ADV-D17, two ADV-D19, and five ADV-D27, which were similar to the serotypes reported in severe pneumonia. Furthermore, three strains of C1 adenovirus were found to be highly homologous to the original strain AF534906 by sequencing, and the phylogenetic trees of the three main structural genes were all on the same branch as the original strain. Base mutations and amino acid variants were found in each structural gene segment. In clinical data, it\u2019s found that patients with mutations are worse than those without mutations. CONCLUSION: Respiratory viruses are common in patients with poor prognosis of AECOPD, especially adenovirus, respiratory syncytial virus. Respiratory virus infections will lead to the deterioration of patients with AECOPD, accompanied by longer treatment cycles and poor prognosis.<\/jats:p>","DOI":"10.3233\/thc-240010","type":"journal-article","created":{"date-parts":[[2024,7,26]],"date-time":"2024-07-26T11:01:14Z","timestamp":1721991674000},"page":"4203-4221","source":"Crossref","is-referenced-by-count":3,"title":["Respiratory
