title: [Effects of maintenance treatment after high-dose intravenous gamma-globulin for idiopathic thrombocytopenic purpura].
abstract: High-dose intravenous immunoglobulin (IVIG) for idiopathic thrombocytopenic purpura (ITP) produces a dramatic and substantial increase in platelet count, but the increased count tends to return rapidly to its pretreatment level. We studied the effects of immunosuppressive treatment aimed at the maintenance of platelet counts following the IVIG administration in ITP. Thirty-five patients with ITP were treated with IVIG, and then thirty-two of them with an immunosuppressant (azathioprine) and a glucocorticoid (prednisolone). After IVIG, the platelet count increased significantly. With immunosuppressive therapy after IVIG, most patients had a tendency to maintain the counts. In particular, this maintaining effect was remarkable in those patients who had been responsive to the standard prednisolone therapy while non-responders to the prior prednisolone failed to maintain the counts. When prednisolone was given after IVIG, the effect of maintaining platelet counts was dose-dependent. The treatment with azathioprine and prednisolone after IVIG appears to be effective in maintenance of platelet counts.
