Trial summary

Trouble breathing (dyspnea) is a nonspecific symptom associated with many diseases such as chronic obstructive pulmonary disease (lung disorder in which the flow of air to the lungs is blocked), asthma, pneumonia, pulmonary hypertension (high blood pressure in the lungs), congestive heart failure (fluid build-up in… Read more about this study

About this study

Official title: Evaluation of ST2 and IL-33 for Risk Stratification and Diagnosis in Patients Presenting to the Emergency Department With Dyspnea

Trouble breathing (dyspnea) is a nonspecific symptom associated with many diseases such as chronic obstructive pulmonary disease (lung disorder in which the flow of air to the lungs is blocked), asthma, pneumonia, pulmonary hypertension (high blood pressure in the lungs), congestive heart failure (fluid build-up in the lungs because the heart is not pumping normally) and pulmonary embolism (blood clot in the lungs). The purpose of this study is to test two blood markers called ST2 and IL-33. Blood markers are proteins or other compounds in your blood that physicians use to diagnose different diseases and to determine what the course of an illness will be. In preliminary research studies, ST2 and IL-33 have been elevated in patients with a wide variety of diseases where the lungs are the primary organs involved. This research study will further investigate the ability of ST2 and IL-33 to predict the severity of disease and the possible use of ST2 and IL-33 in the diagnosis of various lung diseases.

  2. Mortality with a pulmonary specific etiology

    Measured: 180 days

  3. Any cause morbidity

    Measured: 180 days

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease and Asthma, run by The Cleveland Clinic at 1 site in United States.

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 4 inclusion and 5 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 20 Mar 2024. 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 United States. 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?

Any cause of mortality (time frame: 180 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00707811, which also lists 1 linked publication.

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 20 Mar 2024.
