ARCH PATHOL LAB MED:骨髓增生异常综合征患者中性粒细胞中的Howell-Jolly包含物

2018-12-29 MedSci MedSci原创

先前研究表明,Howell -Jolly体样包含物与感染人类免疫缺陷病毒(HIV),服用抗病毒药物和免疫抑制的患者具有一定关联。这些包含物出现在中性粒细胞中,类似于异常红细胞生成中的正常成形细胞的Howell-Jolly体。在粒细胞中,它们被认为代表由发育不良的粒细胞生成产生的分离的核碎片。据我们所知,之前没有关于Howell-Jolly体样包含物和骨髓增生异常综合征(MDS)的关联的研

先前研究表明,Howell -Jolly体样包含物与感染人类免疫缺陷病毒(HIV),服用抗病毒药物和免疫抑制的患者具有一定关联。这些包含物出现在中性粒细胞中,类似于异常红细胞生成中的正常成形细胞的Howell-Jolly体。在粒细胞中,它们被认为代表由发育不良的粒细胞生成产生的分离的核碎片。据我们所知,之前没有关于Howell-Jolly体样包含物和骨髓增生异常综合征(MDS)的关联的研究。因此,本研究旨在-建立MDS患者中Howell-Jolly体样包含物的相关性。

研究人员对诊断MDS的患者的11个骨髓病例和20个没有显著病理改变的骨髓病例进行了回顾性分析。同时,进行详细的医疗记录审查以确保没有患者有HIV病史,或者正在服用免疫抑制剂和/或抗病毒药物。

研究表明,来自研究组的11个病例中的8个(72%)显示少数(<5%)成熟中性粒细胞中的脱落的胞质内包含物与Howell-Jolly体样内含物一致。在对照组中未发现Howell-Jolly体样内含物。值得注意的是,所选择的患者中没有一个患有HIV病史或正在服用免疫抑制剂和抗病毒药物。

在文献综述中,Howell-Jolly体样内含物似乎与免疫抑制和抗核苷酸类似物的抗病毒治疗相关。因此,本研究提出Howell-Jolly体样内含物的形成是发育异常的结果,它不仅与上述病症相关,而且与MDS相关。然而,研究发现仅在少数白细胞(<5%)中看到包含物,这可能是过去病理学家未意识到的原因。本研究旨在提高人们对MDSHowell-Jolly体样包含物的认识并将与病症其联系起来。

骨髓增生异常综合征(MDS)难以确诊,特别是当血液和骨髓细胞的形态学改变很小、原始粒细胞比例未增加、核型正常的时候。在MDS患者中已发现40多个反复发生的体细胞基因突变,这让我们看到了针对这些突变做分子遗传检测的希望,可能会有助于明确诊断某些出现血细胞减少和非确诊性骨髓形态学改变的模棱两可的病例。但是,许多年长的健康个体在白血病相关驱动基因上也携带这些体细胞突变,特别是在DNMT3A、TET2和A
