title: [Expression of anti-platelet glycoprotein specific antibodies and anti-HLA antibodies in idiopathic thrombocytopenic purpura].
abstract: In order to investigate the expression of the anti-platelet glycoprotein specific antibodies and anti-HLA antibodies in idiopathic thrombocytopenic purpura (ITP), 45 patients with ITP were selected in this study. An easy PCR-SSP assay was used to detect single-nucleotide polymorphisms or deletion in HPA and HLA systems. The anti-platelet glycoprotein specific antibodies and anti-HLA antibodies in plasma or platelet eluate were tested with a solid phase ELISA. The results indicated that the anti-platelet glycoprotein specific antibodies were detected in plasma or platelet eluate of 45 patients, among which anti-GPIIb/IIIa/and anti-GpIb/IX were most common. Both the anti-platelet glycoprotein specific antibodies and anti-HLA antibodies were found in plasma of 11 patients. Pedigree investigation in 2 patients (case 37 and case 40) was carried out, the results showed that anti-platelet glycoprotein specific antibodies and anti-HLA antibodies detected in 2 patients closely related to incompatibility with platelet antigens and HLA antigens in parents. In conclusion, the results suggested that detection of the anti-platelet glycoprotein specific antibodies and anti-HLA antibodies in plasma or platelet eluate in combination with investigation of clinical manifestation of patients is important for diagnosis of idiopathic thrombocytopenic purpura.
