Successful treatment with rituximab and mycophenolate mofetil of refractory autoimmune hemolytic anemia post-hematopoietic stem cell transplant for dyskeratosis congenita due to TINF2 mutation.

AIHA following allogeneic HSCT is appearing more frequently in the literature. It occurs as a result of donor cell-derived antibodies targeting donor red cell antigens. Little guidance exists on the management of such patients, particularly in the pediatric setting. First-line conventional treatment is corticosteroids and/or immunoglobulin therapy with monoclonal antibody therapy reserved for treatment failure. We report our experience of a child refractory to immunoglobulin and steroid therapy who required several infusions of rituximab and immunomodulatory therapy to obtain a clinically significant response.
