Can a common steroid stop lung fluid from coming back?
NCT ID NCT07039019
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether the steroid prednisone can prevent recurrent pleural effusions (fluid buildup around the lungs) in people with non-specific pleuritis. Forty adults will be randomly assigned to take prednisone daily for 4 weeks or receive no steroid. The study lasts 6 months and tracks how many people have fluid recurrence and need further procedures.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Prednisone (a corticosteroid)
- What this could lead to
- If it works, this could point toward a simple treatment to prevent fluid buildup in the lungs for people with non-specific pleuritis.
- What could go wrong
- This is a very early pilot study with only 40 people, so results may not be conclusive. Corticosteroids also have side effects like weight gain and increased infection risk.
