Glycyrrhetinic Acid Combined With Dexamethasone in Management of Newly Diagnosed ITP
Study Details
Study Description
Brief Summary
The project was undertaking by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of glycyrrhetinic acid combining with high-dose dexamethasone for the treatment of adults with newly-diagnosed primary immune thrombocytopenia (ITP).

Detailed Description
The investigators anticipate to undertaking a parallel group, single-centre, randomised controlled trial of 30 ITP adult patients. One part of the participants are randomly selected to receive glycyrrhetinic acid (given compound glycyrrhizin tablets orally at a dose of 225mg per day for 1 month), combining with dexamethasone (given orally at a dose of 40 mg per day for 4 days, two-cycles with an interval of 10 days); the others are selected to receive high-dose of dexamethasone treatment plus placebo. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study. In order to report the efficacy and safety of glycyrrhetinic acid combining with high-dose dexamethasone therapy for the treatment of adults with ITP.

Outcome Measures
Primary Outcome Measures
- Sustained response to ITP treatments [3 months after treatment started]
Percentage of patients maintaining PLT count over 30*10^9 without bleeding
Secondary Outcome Measures
- Evaluation of platelet response [3 months after treatment started]
Complete response (CR)# A platelet count ≥ 100 * 10^9/L measured on two occasions > 7 days apart and the absence of bleeding. Response (R)# A platelet count ≥ 30 * 10^9/L and a greater than two fold increase in platelet count from baseline measured on two occasions > 7 days apart and the absence of bleeding. No response (NR)# A platelet count < 30 * 10^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.
