ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the impact of platelet membrane glycoprotein (GP)-specific autoantibodies on high-dose dexamethasone therapy in patients with idiopathic thrombocytopenic purpura (ITP).</p><p><b>METHODS</b>Modified direct monoclonal antibody immobilization of platelet antigen assay (MAIPA) was used to detect platelet GPIIb/IIIa and/or GPI b specific autoantibodies. All patients received oral dexamethasone 40 mg/d for 4 days.</p><p><b>RESULTS</b>The response rate of high-dose dexamethasone in GPIIb/IIIa and/or GPIb specific autoantibody-negative patients was significantly different from that of antibody-positive patients (P<0.05). The response rate of GPIIb/IIIa specific autoantibody-positive patients was lower than that of antibody-negative patients (P<0.05). GPIb specific autoantibody had no significant impact on the efficacy of high-dose dexamethasone (P>0.05).</p><p><b>CONCLUSION</b>Platelet membrane GPIIb/IIIa-specific autoantibody can be a potential negative indicator for ITP patients'response to high-dose oral dexamethasone.</p>
