My wife is 85. Her diagnosis is also aplastic anemia, still current after 7 weeks in the hospital and now for over 4 weeks at home. Meds: 3 cyclosporine and 1 Alvaiz daily, Vitamin B12, few others. For 3 weeks now her platelet level has remained at 21 without an infusion, and she now stays awake most of the day, has returned to cooking meals, moving around the house, even stairs, without extreme worry that she will fall. Helping also, we think, is her return to fruits, vegetables, nuts, greens, fish, poultry, and meats (hospital food wasn't always helpful). Not up to walking longer distance than a block or two, but hopeful. We know that she has a serious illness, currently incurable, and she is not a candidate for stemcell transplant.
She has had a great response to her treatment, it sounds like. Was she given a major treatment while in the hospital, such as horse ATG? Is she on Promacta? I think you are both fortunate with where she is now. So good to hear it.
