My comments assume you have Evans Syndrome or some similar autoimmune cytopenia.Evans syndrome is a rare disorder in which the body’s immune system produces antibodies that mistakenly destroy red blood cells, platelets and sometimes certain white blood cell known as neutrophils.

Medscape: Evans Syndrome
Because of its rarity, information on treatment for Evans Syndrome is limited, but there are many treatments for ITP left to be tried. Some may work when others don't, including dapsone and danazol.emedicine.medscape.com/article/955266-treatment#d9
Medscape: Evans Syndrome Treatment & Management
Splenectomy does not have a clearly established role in the treatment of Evans syndrome, but it may be considered in refractory cases. Splenectomy may improve the CBC and reduce steroid dependence; however, relapses are common and, in most cases, occur within 1-2 months after the procedure.
According to a national survey, splenectomy provided a reported duration of response that ranged from 1 week to 5 years; however, the median response duration was just 1 month.[15] The risk of postsplenectomy sepsis appears to be increased in children with Evans syndrome, especially those with pancytopenia.

Sirolimus is effective in relapsed/refractory autoimmune cytopenias: results of a prospective multi-institutional trial
The initial dose for Nplate is 1 mcg/kg based on actual body weight.
Dose Adjustments
Use the actual body weight at initiation of therapy, then adjust the weekly dose of Nplate by increments of 1 mcg/kg until the patient achieves a platelet count ≥ 50 x 109/L as necessary to reduce the risk for bleeding; do not exceed a maximum weekly dose of 10 mcg/kg. In clinical studies, most patients who responded to Nplate achieved and maintained platelet counts ≥ 50 x 109/L with a median dose of 2 mcg/kg.
During Nplate therapy, assess CBCs, including platelet counts, weekly until a stable platelet count ( ≥ 50 x 109/L for at least 4 weeks without dose adjustment) has been achieved. Obtain CBCs, including platelet counts, monthly thereafter.
Adjust the dose as follows:
If the platelet count is < 50 x 109/L, increase the dose by 1 mcg/kg.
If platelet count is > 200 x 109/L for 2 consecutive weeks, reduce the dose by 1 mcg/kg.
If platelet count is > 400 x 109/L, do not dose. Continue to assess the platelet count weekly. After the platelet count has fallen to < 200 x 109/L, resume Nplate at a dose reduced by 1 mcg/kg.
