Brief summary
Proportion who would avoid splenectomy at 6 months of follow up
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.
Interventions
