Treatment of primary thrombocythemia with platelet separation plus medication:Experence of 22 cases
[Abstract] Objective To observe the clinical effects of platelet separation plus hydroxyurea, INF-α on primary thrombocythemia(PT). Methods All patients were treated with platelet separation and hydroxyurea, INF-α in turn.Results After platelet separation, the platelet count of patients decreased significantly and the symptoms referable to thrombocythemia were improved. Then, all cases were treated with hydroxyurea, INF-α and got obviously amelioration finally. Conclusion The method of platelet separation plus hydroxyurea and INF-α have significant effects on PT.

原發(fā)性血小板增多癥(primary thrombocythemia,PT)是一種慢性骨髓增生性疾病,其特點為外周血血小板持續(xù)顯著增多且功能異常,骨髓巨核細胞增生顯著,臨床表現(xiàn)常有出血傾向和(或)血栓形成,約半數(shù)患者有脾腫大。盡快降低血小板、使血液黏滯度下降,預防血栓及出血的發(fā)生是治療PT的關鍵。我院于2002年1月~2004年12月采取血小板去除術聯(lián)合羥基脲、干擾素-α治療PT患者22例,現(xiàn)將其臨床特征及診療情況報告如下。
