A Pilot Study to Evaluate Safety and Tolerability, Pharmacokinetics, and Preliminary Efficacy of Quercetin in Patients With XIAP (X-linked Inhibitor of Apoptosis) Deficiency
Children's Hospital Medical Center, Cincinnati
Summary
The purpose of the study is to evaluate safety and tolerability of oral quercetin in reducing inflammation in male patients with XIAP deficiency. Quercetin is a naturally occurring antioxidant that has many properties including the ability to decrease inflammation in other diseases.
Description
XIAP deficiency is a rare genetic immune disorder. XIAP usually suppresses inflammation and XIAP deficiency leads to increased inflammation. Patients may develop several inflammatory problems including hemophagocytic lymphohistiocytosis (HLH), a life-threatening syndrome of overwhelming inflammation characterized by fever, low blood counts (cytopenias), an enlarged spleen, liver problems, seizures, and other manifestations. Patients may develop milder symptoms such recurrent fevers or problems with low blood counts. Inflammatory bowel disease (IBD), arthritis or inflammation of the eyes (uveit…

Interventions
- DrugQuercetin
Quercetin will be administered orally at a weight adjusted dose for a maximum total daily dose of 4000mg/day, divided twice a day. If the patient is 70 kg or more, the dose will automatically be assigned at the maximum dose of 4000mg/day. Patients will be instructed to mix quercetin with a small amount of yogurt or other preferred food for ingestion.
