NEJM:JAK抑制剂ruxolitinib治疗遗传性USP18缺乏症

2020-02-20 MedSci MedSci

泛素特异性肽酶18(USP18)缺乏是一种严重的Ⅰ型干扰素病。USP18通过阻断Janus相关激酶1(JAK1)访问I型干扰素受体来下调I型干扰素信号传导。USP18的缺失会导致干扰素介导的炎症,这在围产期是致命的。我们报道了一例患儿,该患儿患有脑积水、坏死蜂窝织炎、全身炎症和呼吸衰竭的新生儿。外显子组测序鉴定出USP18上一个重要剪接位点的纯合子突变。编码蛋白有表达,但无负调控能力。用ruxol

沙特阿拉伯国王大学医学院Abdullah A. Alangari研究小组取得一项新突破。他们研究了JAK抑制剂治疗遗传性USP18缺乏症的效果。这一研究成果发表在2020年1月16日出版的国际学术期刊《新英格兰医学杂志》上。

我们报道了一例患儿,该患儿患有脑积水、坏死蜂窝织炎、全身炎症和呼吸衰竭的新生儿。

外显子组测序鉴定出USP18上一个重要剪接位点的纯合子突变。编码蛋白有表达,但无负调控能力。用ruxolitinib治疗后得以迅速而持续的恢复。
