Conditions

Intervention / Treatment

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.

  • 4.18 years old or more

Exclusion Criteria:
