About this study

Official title: The Optimal Noninvasive Indicator for Identify Pulmonary Hypertension Will be Determined. Difference of Some Indexes Between Bronchiectasis With Pulmonary Hypertension and Bronchiectasis Without Pulmonary Hypertension.

Patients with idiopathic bronchiectasis who received right heart catheterization (RHC) were included to evaluate the consistency between pulmonary arterial pressure (PAP) and other noninvasive indicators (pulmonary arterial systolic pressure [PASP] calculated by echocardiography, main pulmonary artery [MPA] diameter and MPA/ascending aorta ratio on chest high-resolution computed tomography [HRCT]). Then the optimal noninvasive indicator for identify PH was determined and its critical point was obtained according to the Youden Index. Based on this, we investigate the proportion, risk factors and prognosis of PH in idiopathic bronchiectasis patients in another large-scale population.

Read the detailed description

Between April 2011 and December 2019, the data of idiopathic bronchiectasis patients were analyzed to determine the optimal noninvasive tool to identify PH. Based on the patients who received RHC examination, Spearman correlation was used to assess the correlation between mean pulmonary arterial pressure (mPAP) and systolic pulmonary arterial pressure (sPAP) measured by RHC and other noninvasive indicators (estimated PASP assessed by echocardiography, main pulmonary artery (MPA) diameter and MPA/ ascending aorta (AA) ratio on chest HRCT scan), in order to screening out the optimal indicator to identify PH. Then the sensitivity and specificity of the indicator was calculated through the receiving operating characteristics (ROC) analysis and the critical point of the indicator was determined by Youden index.

Based on critical point of that indicator, a large sample study from hospital medical database for patients with idiopathic bronchiectasis in Shanghai Pulmonary Hospital (Shanghai, China) between May 2013 and December 2019 was conducted. The following data were collected: demographic information (i.e., age and sex); clinical characteristics (age of symptom onset, duration after bronchiectasis diagnosis, and body mass index [BMI]); radiological presentation (the type of bronchiectasis, and involved lung lobe and segment); pulmonary function (forced vital capacity [FVC], forced expiratory volume in 1 second [FEV1], and FEV1/FVC); N-terminal pro brain natriuretic peptide (N-proBNP); arterial blood gas and microbiological detection in respiratory tract specimen (sputum or bronchoalveolar lavage fluid). The number of hospitalizations and emergency visits in past 12 months before the first hospitalization were collected based on patient's medical records. Patients were followed up by telephone until December 2021.

The idiopathic patients who received echocardiography examination were divided into two groups. The risk factors of PH associated with idiopathic bronchiectasis and the effect of PH on the prognosis of patients with bronchiectasis were analyzed through statistical method.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The optimal noninvasive indicator for identify pulmonary hypertension

    Based on the patients who received right heart catheterization examination, the optimal noninvasive indicator for identify PH was determined

    Measured: April/01/2011-Decemeber/31/2019

  2. Differance of some indexes between Bronchiectasis with pulmonary hypertension and Bronchiectasis without pulmonary hypertension

    Differance of some indexes (ie. course, clinical presentation, type and scope of bronchiolitis, lung function, pseudomonas aeruginosa in respiratory tract specimen and prognosis) between Bronchiectasis with pulmonary hypertension and Bronchiectasis without pulmonary hypertension

    Measured: May/01/2013-Decemeber/31/2019

Questions about this trial

What is this clinical trial studying?

An observational study of Bronchiectasis and Pulmonary Hypertension, run by Shanghai Pulmonary Hospital, Shanghai, China 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 3 inclusion and 7 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 3 Oct 2023. 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?

The optimal noninvasive indicator for identify pulmonary hypertension (time frame: April/01/2011-Decemeber/31/2019). The study lists 2 primary outcomes in all. 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 3 Oct 2023.
