Proportion who would avoid splenectomy at 6 months of follow up


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.

Medical and Biotech [MESH] Definitions

Chronic refractory anemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells.

Proteins found usually in the cytoplasm or nucleus that specifically bind steroid hormones and trigger changes influencing the behavior of cells. The steroid receptor-steroid hormone complex regulates the transcription of specific genes.

The period of time following the triggering of an ACTION POTENTIAL when the CELL MEMBRANE has changed to an unexcitable state and is gradually restored to the resting (excitable) state. During the absolute refractory period no other stimulus can trigger a response. This is followed by the relative refractory period during which the cell gradually becomes more excitable and the stronger impulse that is required to illicit a response gradually lessens to that required during the resting state.

A 21-carbon steroid, derived from CHOLESTEROL and found in steroid hormone-producing tissues. Pregnenolone is the precursor to GONADAL STEROID HORMONES and the adrenal CORTICOSTEROIDS.

A 21-carbon steroid that is converted from PREGNENOLONE by STEROID 17-ALPHA-HYDROXYLASE. It is an intermediate in the delta-5 pathway of biosynthesis of GONADAL STEROID HORMONES and the adrenal CORTICOSTEROIDS.
