Can a blood marker reveal how rehabilitation affects axial spondyloarthritis?
NCT ID NCT07821541
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers at Giresun University are studying whether a blood protein called calprotectin changes in people with axial spondyloarthritis who complete a four-week pulmonary rehabilitation program. Thirty patients aged 25 to 65 will take part. The team will measure calprotectin alongside other inflammation markers, lung function, disease activity scores, and quality-of-life questionnaires before and after rehabilitation to see how these measures relate to each other.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a four-week pulmonary rehabilitation program
- What this could lead to
- If calprotectin tracks with disease activity, doctors may gain a simple blood marker to follow axial spondyloarthritis over time.
- What could go wrong
- The study is small, with 30 participants, and it only observes changes during rehabilitation. It cannot prove that rehabilitation causes any shift in calprotectin or that the marker predicts long-term outcomes.
