Anti-D immunoglobulin-induced prolonged intravascular hemolysis and neutropenia.
Intravenous anti-D immunoglobulin (anti-D IVIG) is indicated for the treatment of immune thrombocytopenic purpura (ITP) in nonsplenectomized patients who are Rh(D)-positive. Recent reports have described episodes of intravascular hemolysis after anti-D IVIG. We report an adolescent boy with chronic ITP who required multiple transfusions of erythrocyte suspensions when intravascular hemolysis persisted for 6 months after anti-D IVIG treatment. He did not have hemolytic anemia before treatment. The features of our case suggest that pediatric patients treated with anti-D IVIG for ITP should be closely monitored for signs and symptoms of hemoglobinemia and/or hemoglobinuria, and clinically significant anemia. Our case proposes that persistence of immune hemolysis after this treatment may be related to presence of previously defined predisposing agents like tuberculosis and antituberculous therapy. Our observations suggest that steroid therapy can be effective in patients who developed prolonged hemolytic anemia and neutropenia after anti-D IVIG therapy.
