Abstract

Immune thrombocytopenia is an acquired thrombocytopenia caused by antiplatelet autoantibodies. Corticosteroids is used as first-line therapy. In the cases of refractory with corticosteroids, splenectomy, rituximab and thrombopoietin receptor agonists are tried as second-line treatments. However, there are some concerns such as serious infections, thrombosis or bone marrow fibrosis although these treatments have high efficacy rate. We herein described three cases of secondary immune thrombocytopenia with treated with tacrolimus with a brief review of literature. Tacrolimus may have therapeutic potential for secondary immune thrombocytopenia, particularly in patients with low complement levels and/or non-responders to H. pylori eradication therapy.
