A Pilot Study of Moderate Hyperbilirubinemia in Type 1 Diabetes Mellitus

• Status: Completed
• Trial end date: 2014-02-01
• Target enrollment: 0
• Participant gender: All

Summary

Specific Aim: To establish the feasibility of studying the change in endothelial function caused by induced moderate hyperbilirubinemia in type 1 diabetes. Atazanavir, a drug that inhibits bilirubin conjugation, will be used to induce moderate hyperbilirubinemia. Endothelial function will be measured before and after atazanavir therapy. In addition, plasma markers of antioxidant capacity and oxidant stress will be measured as proof-of-concept that induced moderate hyperbilirubinemia has favorable effects on oxidative stress in type 1 diabetes.

• Phase: Phase 1
