Abstract

Objective: To study the prevalence of respiratory viral infection in chronic obstructive pulmonary disease(COPD) exacerbations and to find the factors associated with susceptibility to viral infections. Methods: Eighty patients with exacerbations of COPD and 50 stable COPD patients were recruited. Nasopharyngeal swabs were tested for a range of 18 different respiratory viruses using PCR. Results: Among the COPD exacerbations, viral infection was detected in 18 episodes (22.5%) . The most common virus was rhinovirus (33.3%), followed by coronavirus(27.8%), parainfluenza(22.2%), metapneumovirus(11.1%) and influenza virus B(5.6%). The prevalence of viral infection was 8% in the stable COPD patients. In multivariate regression analysis fever was found to be significantly associated with viral infections in COPD exacerbations (Odds ratio 4.99, 95%CI 1.51-16.48, P=0.008). Conclusion: Viral respiratory pathogens were more often detected in respiratory specimens from hospitalized patients with AECOPD than those with stable COPD. Rhinovirus was the most common infecting agent identified. The symptom of fever was associated with viral detection.

  1. I was diagnosed of Chronic Obstructive Pulmonary Disease (COPD) in summer of 2014, my symptoms started out with shortness of breath and chronic cough. The pulmonary disease specialist prescribed me some medications to help my symptoms however the medications did no good and their side effects were too severe. In May 2016, i started on NewLife Herbal Clinic COPD Herbal formula treatment, i read alot of positive reviews on their success rate with the COPD Herbal formula and i immediately started on the treatment. Just 11 weeks into the Herbal formula treatment I had great improvements with my breathing, there is no case of dyspnea and chest tightness since treatment, visit NewLife Herbal Clinic official website www. newlifeherbalclinic. com or email info@ newlifeherbalclinic. com. This treatment is incredible!
