Massive study reveals hidden dangers of common steroid treatments
NCT ID NCT06488703
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at over 107,000 patients in Germany to understand the long-term side effects of systemic steroids (corticosteroids) used for conditions like asthma, COPD, and arthritis. Researchers compared patients who took steroids with those who did not, tracking risks such as diabetes, heart disease, osteoporosis, and infections. The goal was to measure how often these side effects occur and their economic impact on the healthcare system.
