免疫学免疫学免疫学
遗传学是一个遗传学.
类风湿病学类风湿病学

背景情况:

发病于婴儿期的刺痛相关血管病变 (SAVI) 是一种罕见的I型干扰症.
它是由STING基因的功能增益变异引起的,导致I型干扰素信号过活.
这种过度激活会导致自身炎症,免疫缺陷和自身免疫.

研究的目的:

强调早期遗传检测和JAK抑制剂治疗的重要性.

主要方法:

一个5岁的孩子和他的母亲患有SAVI的案例报告.
基因检测在两名患者中都发现了异合性STING R281Q变体.
分析了临床表现,器官参与和治疗反应.

主要成果:

这两名患者均携带STING R281Q变异,此前与SAVI相关.
患者表现出非典型的SAVI表现:儿童全身脱发,母亲没有肺部感染.
疾病的进展和治疗反应在母亲和孩子之间有显著的差异.

结论:

SAVI表现出广泛的临床表型.
建议在患有无法解释的全身炎症的患者进行SAVI早期遗传检测.
雅克抑制剂对SAVI症状具有治疗效益.

Vascular Spasm

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...
