低增生性骨髓增生异常综合征临床分析

 目的 探讨低增生性骨髓增生异常综合征（hypo-MDS）的临床特征、实验室指标及治疗。方法 对8例hypo-MDS患者的临床特点、骨髓涂片及骨髓活检结果进行分析，用流式细胞仪测定T细胞亚群，采取个体化治疗方案，随访观察疗效。结果 8例患者均有2个以上部位骨髓增生低下、骨髓低细胞容积和不同程度病态造血。T细胞亚群分析结果显示5例有T细胞数目、CD+4／CD+8比例异常。治疗后2例基本缓解，3例部分缓解，2例进步，1例无效。结论 hypo-MDS以骨髓低细胞容积和病态造血为共同特征，表现为细胞免疫异常，采取个体化治疗原则可延长患者生存期。

The clinical analysis of hypoplastic myelodysplastic syndrome

Objective To study the clinical features, laboratory index and therapy of hypoplastic myelodysplastic syndrome. Methods 8 patients with hypoplastic MDS by using the method of bone marrow smear and bone marrow biopsy were studied. T lymphocyte subsets were analyzed by flow cytometry. 8 patients were treated with personalized therapy. Results All the patients of this group had hypoplastic bone marrow with more than two parts, bone marrow hypocellularity and characteristics of ineffective hematopoiesis. The analysis of T lymphocyte subsets showed that 5 of 8 patients had abnormal CD+4/CD+8 ratios. After personalized treatment, there were 2 obvious remission cases, 3 partial remission cases, 2 progression cases and 1 inefficacy case. Conclusion Hypoplastic MDS is characterized by bone marrow hypocellularity and ineffective hematopoiesis, which showed immunological abnormalities. Personalized therapeutic strategy may prolong survival in patients with hypoplastic MDS.
