Arthritis drug may mask diabetes, study warns
NCT ID NCT07416656
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether sulfasalazine, a drug for inflammatory arthritis, makes the standard diabetes blood test (HbA1c) falsely low. That could mean diabetes goes undiagnosed or is undertreated in these patients. Researchers will use continuous glucose monitors and fasting blood sugar tests in 75 adults to find out how often this happens.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
sulfasalazine
What this could lead to
If successful, this could lead to better diabetes screening guidelines for people with inflammatory arthritis taking sulfasalazine.
What could go wrong
This is a small, observational study (75 people) that only identifies a problem—it does not test a new treatment or solution.
