Primary Outcome Measures:
  • Proportion who would avoid splenectomy at 6 months of follow up [ Time Frame: 2years ] [ Designated as safety issue: Yes ]
    Proportion who would avoid splenectomy at 6 months of follow up


Secondary Outcome Measures:
  • SR,IR [ Time Frame: 2years ] [ Designated as safety issue: Yes ]
    Sustained response (platelet count that remained above 30X109/L or 2 folds of initial platelet count at 6 months of follow up) Initial response (an increase in the platelet count of at least 10X109/L or a platelet count of more than 30X109/L by day 7 after the initiation of treatment) Changes of platelet counts Safety of treatment Response rate of HP infected patients Decrement of steroid dose Predictors of response


Estimated Enrollment: 38
Study Start Date: February 2010
Estimated Study Completion Date: January 2012
Estimated Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Steroid dependant ITP
more than 10 mg of prednisolone per day is required to maintain a platelet count above 20X109/L (minimum follow up duration: 3 months after diagnosis)
 Other: Steroid refractory ITP
a platelet count less than 20X109/L despite of treatment with full dose of steroid (prednisolone 1mg/kg for at least 4 weeks)
Other Name: prednisolone 1mg/kg

Detailed Description:

  1. If urea breath test (+); omeprazole 20mg bid, amoxicillin 1000mg bid and clarithromycin 500mg bid for 1 week.

    Second line Helicobacter pylori eradication will be permitted after failure of first line treatment.

  2. Anti-D Anti-Ro 50 μg/kg IV for 2 days (D1, 2)
  3. Danazol maintenance (from D1): Danazol will be continued at least 3 months. The dose of danazol can be reduced according to the adverse effects, especially in premenopausal women.
