Aplastic anemia (AA) is an immune‐mediated disease. Although most patients are responsive to immunosuppressive therapy (IST) with a combination of anti‐thymocyte globulin (ATG) and cyclosporine (CsA), some patients relapse or are refractory to IST. Sirolimus (rapamysin) inhibits the serine–threonine kinase mammalian target of rapamysin (mTOR), and blocks CsA‐resistant and calcium‐independent pathways late in the progression of the T‐cell cycle. We report two cases of AA which relapsed after CsA and ATG plus CsA, respectively. They achieved transfusion independence after retreatment with sirolimus in combination with a CsA.
