Trial summary

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the main factor that leads to the deterioration of the disease. Currently, the diagnosis of AECOPD mainly relies on clinical manifestations, and good predictors or biomarkers are lacking. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 to 90 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Patients with stable COPD and AECOPD and healthy controls were recruited from the Second Affiliated Hospital of Zhejiang University School of Medicine and Yuhang District of the Second Affiliated Hospital of Zhejiang University, Hangzhou, China.

Who may be able to join

  • Over 40 years old.
  • in line with the diagnostic criteria in GOLD 2018.
  • with the ability to sign informed consent.
  • can be followed up according to the study protocol.
  • Patients who were over 40 years old were eligible for inclusion if they had a diagnosis of COPD in their primary care clinical record and were presenting with an acute exacerbation of respiratory symptoms.
  • Healthy people over 40 years old.

Who cannot join

  • with other pulmonary diseases (such as lung cancer, sarcoidosis, tuberculosis, pulmonary fibrosis, cystic fibrosis) and severe α1-antitrypsin deficiency.
  • with other inflammatory diseases (such as rheumatoid arthritis and inflammatory bowel disease, etc.).
  • a history of pulmonary surgery, or a diagnosis of malignant tumor recently.
  • a history of blood transfusion in 4 weeks.
  • participating in a double-blind drug clinical trial.
  • unable to walk.

  • using oral or intravenous steroid therapy.
  • with acute exacerbation in 4 weeks.
  • For AECOPD:
  • Other specific diseases that may account for sudden changes in respiratory symptoms should be excluded by clinical or laboratory tests.
  • The remaining exclusion criteria were consistent with the above five criteria in stable COPD.
  • The control group:
  • with chronic airway diseases and other lung diseases, and heart, kidney, liver, and other important organ diseases.

About this study

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the main factor that leads to the deterioration of the disease. Currently, the diagnosis of AECOPD mainly relies on clinical manifestations, and good predictors or biomarkers are lacking. This study aims to explain the gene expression changes related to the disease at the transcriptional level and validate it in multiple levels, reveal specific biomarkers and potential pathogenesis, to provide a research basis for the diagnosis and treatment of AECOPD.

Questions about this trial

What is this clinical trial studying?

An observational study of COPD Exacerbation, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Differentially expressed genes of 13 participants as assessed by RNA sequencing (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2021.
