研究目的:

(1)比较具有胚系突变的有胚系突变的难治性血小板减少症患者与经典ITP患者之间血常规(包括红细胞体积、血小板体积等)、免疫相关指标的差异,并探讨其潜在的生物学意义。 (2)比较WES检测具有胚系突变的患者与经典ITP患者的发病年龄、病史,探讨是否存在显著差异,并进一步讨论其影响因素与发展趋势。 (3)分析WES检测具有胚系突变的血小板减少症患者中骨髓CD34的表达水平,疗效,并与经典ITP患者进行对比,以揭示其在疾病发展中的可能作用。  

Objectives of Study:

(1) Compare the differences in blood routine (including red blood cell volume, platelet volume, etc.) and immune-related indexes between patients with refractory thrombocytopenia with germline mutations and patients with classical ITP, and explore their potential biological significance. (2) Compare the age of onset and medical history between patients with germline mutations by WES test and patients with classical ITP, and explore whether there are significant differences, and further discuss their influencing factors and development trends. (3) To analyze the expression level of bone marrow CD34 in thrombocytopenic patients with germline mutations detected by WES, the efficacy of the treatment, and to compare them with patients with classical ITP, in order to reveal their possible role in the development of the disease.
