再生障碍性贫血-阵发性睡眠性血红蛋白尿综合征与典型阵发性睡眠性血红蛋白尿症的临床对照研究

Study on the clinical features of patients with aplastic anemia-paroxysmal nocturnal hemoglobinuria syndrome and typical paroxysmal nocturnal hemoglobinuria.

目的 研究再生障碍性贫血 -阵发性睡眠性血红蛋白尿综合征 (AA PNH综合征 )与典型阵发性睡眠性血红蛋白尿症 (PNH)临床特征的异同 ,加深对AA PNH综合征的认识。方法 回顾分析了 2 8例AA PNH综合征和 5 1例典型PNH的临床表现、实验室检查及治疗反应 ,并进行了对照研究。结果 AA PNH综合征与典型PNH相比 :①血栓形成、黄疸、肝脾肿大等临床表现均较轻。②网织红细胞虽较低 ,但仍高于正常 ;骨髓涂片及活检多表现为增生减低 ,但红系比例不低 ;③各溶血指标检查阳性率均较低 ,但CD5 5、CD5 9表达异常的检出率为10 0 % ,且其在红细胞、粒细胞、淋巴细胞中表达的百分率在两组患者中无明显差异。④免疫球蛋白、T细胞亚群的检测 ,两组患者均无异常。⑤两组患者对肾上腺糖皮质激素为主的治疗均反应良好。结论 AA PNH综合征虽临床表现有别于典型PNH ,但与典型PNH无本质区别 ;CD5 5、CD5 9的检测有助于提高AA

Objective To explore the differences of clinical features and relationship between aplastic anemia paroxysmal nocturnal hemoglobinuria syndrome(AA PNH syndrome)and typical paroxysmal nocturnal hemoglobinuria(t PNH).Methods A case control study on the discrepancies of clinical and laboratory features between patients with AA PNH syndrome and t PNH was carried out.Results Compared with t PNH,AA PNH syndrome showed following features:①Lower frequencies of venous thrombosis,jaundice and enlarged liver or spleen.②Higher percentages of pancytopenia and bone marrow hypoplasia.③Lower percentages of positive hemolysis tests.The percentages of CD55 and CD59 of peripheral blood cells were not significantly different in most cases of both groups.④Immunoglobulins and subgroups of T lymphocytes were normal in cases of both groups.⑤Adrenocortical hormone was effective in cases of both groups.Conclusion AA PNH syndrome shares a same pathophysiology with t PNH;CD55 and CD59 tests can improve the diagnosis of AA PNH syndrome.
