Remission of aplastic anemia induced by treatment for Graves disease in a pediatric patient.

Aplastic anemia (AA) is mediated by T-cell autoimmunity in the majority of cases; it is rare and mostly idiopathic in children. We describe a child, who developed AA following Graves' disease which could not be attributed to antithyroid drugs. We hypothesized that both diseases were caused by similar autoimmune process. We monitored the blood counts and did not administer any conventional treatment for AA assuming that the existing anti- hematopoietic stem cell humoral and cellular immunity might subside with induction of remission of Grave's disease. The child went into complete remission with the treatment of the Graves' disease.
