The treatment response in aplastic anemia, unlike in other autoimmune diseases, is slow. At least 4-12 weeks is usually needed to observe early improvement, and the patient may continue to improve slowly thereafter. Late responses may also occur. About 50% of patients respond by 3 months after ATG administration, and about 75% respond by 6 months. Full hematologic recovery is rare, but most patients improve to a functional hematologic recovery and become transfusion independent.
