Ketotifen for Children with Functional Dyspepsia and Duodenal Eosinophilia

This study is testing if ketotifen, an anti-allergy medication, can help children aged 8-17 who have functional dyspepsia (ongoing stomach pain) and a specific type of inflammation in their small intestine called duodenal eosinophilia. These children have not found relief from standard acid-reducing medicines. The study compares ketotifen to a placebo (an inactive pill) to see if ketotifen can reduce symptoms. To join, children must have had an endoscopy showing more than 20 eosinophils (a type of white blood cell) in their duodenal biopsies. The study aims to see if ketotifen improves symptoms in these children. The current recruitment status is unclear.

Study design
This is a double-blind, placebo-controlled, cross-over study with 40 planned participants. This means neither you nor the study staff will know if you are receiving ketotifen or the placebo at first.
What's involved
You would have 3 to 4 clinic visits and 2 to 3 phone interviews over 63 to 147 days. Clinic visits include a physical exam, blood draws, questionnaires, and a review of your medical history and medications.
Compensation
Not stated in the trial record.
Follow-up
Your physical, blood pressure, and liver function will be measured at day 0, day 28, day 63, and day 147.
