1 The Role of Viral Infection in Acute Exacerbations of Non-cystic Fibrosis Bronchiectasis in Adults

Bronchiectasis is clinically characterized by irreversible dilation of the bronchi and bronchioles leading to persistent cough, purulent sputum, and airway flow limitation, which may be accompanied by recurrent exacerbations.It has been increasingly recognized that respiratory viruses are mainly responsible for acute exacerbation of chronic pulmonary diseases, i.e. asthma, chronic obstructive pulmonary disease and cystic fibrosis. However,little is known about the roles of viral infection in driving exacerbations of bronchiectasis.This study aims to identify the frequency of common viral infections and determine the roles that viruses play in acute exacerbations of bronchiectasis.

NCT01801657 Bronchiectasis
MeSH:Bronchiectasis Virus Diseases
HPO:Bronchiectasis

Primary Outcomes

Description: Respiratory viruses in the nasal swab and sputum will be identified using the polymerase chain reaction(PCR)technique when clinically stable and during exacerbation.The following viruses will be tested for:influenza A,B(including influenza A H1N1),respiratory syncytial virus(RSV),Enterovirus,Parainfluenza 1-4,Rhinovirus,human Coronaviruses(subtypes OC43、229E、HKU1),human metapneumovirus,adenovirus, human bocavirus,chlamydia,mycoplasma.

Measure: The prevalence of respiratory virus infection in adults with bronchiectasis during a pulmonary exacerbation and when clinically stable.

Time: 1 year

Secondary Outcomes

Description: Systemic and airway inflammatory cytokines including IL-1β、IL-6、IL-8、TNF-a were measured using a commercial multiplex bead-based assay.

Measure: The effect of respiratory virus infection on systemic and pulmonary inflammatory markers.

Time: 1 year

Description: Spirometric indices in the present study is referred to as forced expiratory vilume in 1s(FEV1),forced vital capacity(FVC).Spirometry tests are carried out using a spirometer (COSMED, QUARK PFT, Italy). All operation procedures meet the joint recommendation by ATS and ERS. A total of at least 3 (not more than 8) spirometric maneuvers are performed, with the variation between the best two maneuvers of <5% or 200ml in FVC and FEV1. The maximal values of FVC and FEV1 are reported.

2 SequelaeCov: a Prospective Study on Lung Damage Caused by SARS-CoV-2 Pneumonia

Pneumonia is a recurrent element of COVID-19 infection, it is often associated with development of respiratory failure and patients frequently need various degrees of oxygen therapy up to non invasive ventilation (NIV-CPAP) and invasive mechanical ventilation (IMV). Main purpose of this study is to evaluate with non invasive clinical instruments (pletysmography, Diffusion lung capacity for carbon monoxide -DLCO-, six minute walking test and dyspnea scores) and radiological tools (chest X-ray and chest CT scan) the development of medium-to-long term pulmonary sequelae caused by SARS-CoV-2 pneumonia.
