What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether a simple lung ultrasound can tell the difference between a sudden COPD flare-up and stable disease. It will compare ultrasound images, breathing tests, and exercise ability in about 60 people—those with an acute exacerbation, those with stable COPD, and healthy controls. The goal is to see if ultrasound findings, like B-lines and consolidations, relate to how breathless patients feel and how well they can move. If it works, lung ultrasound could become a quick, non-invasive way to check disease severity at the bedside.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could establish lung ultrasound as a reliable bedside tool to quickly assess COPD severity and guide management.
What could go wrong
This is a small, observational study, so results may not apply broadly. Ultrasound findings may not strongly correlate with symptoms or function.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults aged 40-75 years will be recruited from Munzur University and Tunceli State Hospital. The study population will consist of three groups: patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), patients with clinically stable COPD, and age-matched healthy controls. Eligible participants will be enrolled consecutively after providing written informed consent and will undergo standardized assessments, including lung ultrasound, pulmonary function testing, functional capacity tests, dyspnea evaluation, and psychological assessments.

Ages

40 to 75 years

You do not need to have the condition being studied to take part.
