人偏肺病毒(hMPV)是最近发现的一种与细支气管炎、肺炎、哮喘和哮喘加重相关的呼吸道病毒。由于呼吸道病毒经常在慢性阻塞性肺病急性加重期(AE-COPD)患者中检测到,因此我们的目的是通过实时定量RT-PCR的方法,研究在住院的AE-COPD患者与稳定型COPD患者和非吸烟者的前瞻性队列中hMPV检测的频率。我们分析了130例AE-COPD患者、65例稳定期COPD患者和34例非COPD吸烟者的鼻腔灌洗和诱导痰。在3/130例(2.3%)的AE-COPD患者中检测到HMPV,鼻灌洗液中平均检测到6.5 × 105病毒拷贝/ml,诱导痰中平均检测到1.88 × 105病毒拷贝/ml。在稳定期COPD患者或无COPD的吸烟者中未发现。HMPV仅在极少数急性阻塞性肺病患者中发现。然而,由于无症状携带不太可能,因此应将其视为进一步可能的AE-COPD病毒触发因素。
Human metapneumovirus (hMPV) is a recently discovered respiratory virus associated with bronchiolitis, pneumonia, croup and exacerbations of asthma. Since respiratory viruses are frequently detected in patients with acute exacerbations of COPD (AE-COPD) it was our aim to investigate the frequency of hMPV detection in a prospective cohort of hospitalized patients with AE-COPD compared to patients with stable COPD and to smokers without by means of quantitative real-time RT-PCR. We analysed nasal lavage and induced sputum of 130 patients with AE-COPD, 65 patients with stable COPD and 34 smokers without COPD. HMPV was detected in 3/130 (2.3%) AE-COPD patients with a mean of 6.5 × 105 viral copies/ml in nasal lavage and 1.88 × 105 viral copies/ml in induced sputum. It was not found in patients with stable COPD or smokers without COPD. HMPV is only found in a very small number of patients with AE-COPD. However it should be considered as a further possible viral trigger of AE-COPD because asymptomatic carriage is unlikely.
