ABSTRACT
Stem cell transplantation remains the curative option for many patients with hematological malignancies. The long-term effects of these treatments on the patients and their immune systems have been extensively investigated, but there remains a paucity of data regarding autoimmune manifestations post-transplant, although these effects are well recognized.Herein we present the clinical picture and therapeutic approach in three patients (cases 1-3), with varied presentations of autoimmune disease post-transplant. Case 1 exhibited autoimmune hemolytic anemia and other autoimmune manifestations (serositis, thyroiditis), that were probably linked to graft versus relapsed leukemia effect. Cases 2 and 3 had pure red white cell aplasia and pure red cell aplasia, respectively, which were associated with hyperglobulinemia and a clonal T cell expansion.
