【摘要】:目的建立流式細胞術檢測藥物依賴性血小板抗體的標準方法。方法針對1名再生障礙性貧血患者的血小板抗體檢測,通過ELISA法檢測其血漿中和血小板上特異性和自身抗體,用Lifecodes LSATM Class I(Luminex試劑盒,磁珠液相懸浮芯片系統(tǒng))檢測患者血漿中HLA-Ⅰ類抗體特異性;以流式細胞術檢測患者血漿中兩性霉素B依賴的血小板抗體。結果 ELISA法檢測:血小板特異性抗體和自身抗體均為陰性;Luminex試劑盒測得:患者血清中HLA-Ⅰ類抗體陽性率為1%,未檢出有特異性的HLA-Ⅰ類抗體。流式細胞術檢測:患者血漿中存在兩性霉素B依賴的血小板抗體。結論流式細胞術或可成為檢測藥物依賴性血小板抗體的實驗室標準手段,為臨床預防和治療藥物引起的血小板減少癥提供可靠的理論和技術保障。
[Abstract]:Objective to establish a standard method for detection of drug-dependent platelet antibodies by flow cytometry. Methods Platelet antibodies were detected by ELISA in a patient with aplastic anemia. The specific and autoantibodies in plasma and platelets were detected by Lifecodes LSATM Class I (Luminex kit. The specificity of HLA-I antibody in plasma was detected by magnetic bead suspension microarray system, and the platelet antibody dependent on amphotericin B in plasma was detected by flow cytometry. Results ELISA assay showed that both platelet specific antibody and autoantibody were negative Luminex test kit. The positive rate of HLA-I antibody in serum was 1 and no specific HLA-I antibody was detected. Flow cytometry: Amphotericin B-dependent platelet antibodies were present in patients' plasma. Conclusion flow cytometry may be a laboratory standard for the detection of drug-dependent platelet antibodies and provide a reliable theoretical and technical guarantee for clinical prevention and treatment of drug-induced thrombocytopenia.
