An Investigation of Dexamethasone With Different Doses in the Management of Immune Thrombocytopenia (ITP)
- Registration Number
- NCT02153060
- Lead Sponsor
- Shandong University
- Brief Summary
The project was undertaking by Qilu Hospital of Shandong University and other 7 well-known hospitals in China. In order to report the efficacy and safety of different dose dexamethasone in treating the immune thrombocytopenia (ITP).
- Detailed Description
The investigators are undertaking a parallel group, multicentre, randomised controlled trial of 60 adults with ITP from 7 medical centers in China. Part of the participants are randomly selected to receive dexamethasone (given at a dose of 40mg per day for 4 consecutive days) ,the others are selected to receive dexamethasone(given at a dose of 20 mg daily for 4 days).
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 different dose dexamethasone for the treatment of adults with immune thrombocytopenia (ITP).

- Primary Outcome Measures
Name Time Method Proposed criteria for assessing early response to ITP treatments 3 months 1. Complete response (CR)： A platelet count ≥ 100 \* 10\^9/L measured on two occasions \> 7 days apart and the absence of bleeding.
2. 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.
3. 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.
- Secondary Outcome Measures
Name Time Method Safety 1 years The type and frequency of therapy associated adverse events
