Intravenous immunoglobulin for autoimmune thrombocytopenic purpura.
Severe autoimmune thrombocytopenic purpura is now commonly treated with high doses of intravenous immunoglobulins (IVIGs). Twenty-four years after this treatment was first demonstrated to be effective, several questions remain to be resolved. We review here current knowledge concerning the frequency and type of side effects and the likely mechanism of action of IVIGs. We suggest that the currently recommended dose of IVIG (2 g/kg) could be halved, that the total dose of IVIG should be administered as a single infusion, that nonresponders could be provided another equal dose on day 3, and that IVIG plus prednisolone should be considered the gold standard for treatment of the most severe forms of the disease. Treatment with anti-D immunoglobulin could be proposed as an alternative if the results recently obtained with high doses (75 microg/kg) are confirmed. Finally, because IVIG has only a transient effect, it cannot be considered a curative treatment for patients with chronic autoimmune thrombocytopenic purpura.
