Can your diet impact chronic hives? new study investigates
NCT ID NCT07431658
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how diet and oxidative stress (an imbalance of harmful molecules in the body) relate to chronic spontaneous urticaria (CSU), a condition causing itchy hives and swelling. Researchers will compare adults with active CSU to healthy volunteers, tracking their diet and measuring oxidative stress markers in blood. For CSU patients receiving omalizumab, these factors will be reassessed after 3 months to see if they change with treatment response.
