Treatment and outcome of autoimmune hematologic disease in common variable immunodeficiency (CVID)

Common variable immunodeficiency (CVID) is associated with autoimmunity, most commonly immune thrombocytopenic purpura (ITP) and autoimmunity hemolytic anemia (AIHA). In a retrospective chart review of 326 CVID patients, 35 (11%) patients had a history of autoimmune hematologic disease. Fifteen patients had ITP, 9 had AIHA, and 11 had Evans syndrome (both ITP and AIHA). The age at diagnosis for CVID ranged from 5 to 66 years and for autommumity, from 2 to 66 years. There were 16 males and 19 females. Nineteen patients (54%) had the first episode of thrombocytopenia or hemolytic anemia prior to the diagnosis of immunodeficiency, It (32%) were diagnosed concurrently, and 5 (14%) developed one or both of these autoimmune diseases following the diagnosis of CVID. Eight patients were known to have granulomatous changes in one or more organs. Treatments for autoimmunity included corticosteroids, anti-Rh immunoglobulin, and intravenous immunoglobulin; 11 patients underwent splenectomy. While 5 patients had recurrences of autoimmune hemolytic disease while receiving maintenance intravenous immunoglobulin, most episodes occurred for subjects not yet on this therapy (P < 0.0001). Most patients with frequent infections and hematologic autoimmunity should be evaluated for CVID. (c) 2005 Elsevier Ltd. All rights reserved.
