Ro等875人接种破伤风疫苗均属正常。基因测序发现STAT1中存在R274Q杂合突变。先前的记录显示,她的母亲和姐妹也在信号转导和转录激活因子1(STAT1)基因上发生了功能增强突变。患者的疾病表现主要是她的三叉神经区的皮肤。她的病程也因表面感染甲氧西林敏感的金黄色葡萄球菌、传染性软骨病和溃烂而变得复杂。她没有任何自身免疫异常。她的皮肤真菌感染用口服伊曲康唑、1%克霉唑乳膏和0.1%曲安奈德乳膏治疗,而口服伊维菌素则需要根除溃疡。对于她的浅表葡萄球菌感染,她接受了两个疗程的头孢氨苄治疗,然后预防性服用磺胺甲恶唑/甲氧苄啶。通过上述治疗方案,她的临床症状有所改善,随后的酵母菌筛查仍为阴性。
Ro et al 875 to tetanus vaccination was normal. Genetic sequencing identified a heterozygous R274Q mutation in STAT1. Prior records revealed that her mother and sisters also had gainof-function mutations in the signal transducer and activator of transcription 1 (STAT1) gene. The patient’s disease manifestation was primarily cutaneous in her intertriginous regions. Her course was also complicated by superficial infections with methicillin-sensitive Staphylococcus aureus and molluscum contagiosum as well as scabies. She did not have any autoimmune abnormalities. Her cutaneous fungal infection was treated with oral itraconazole, clotrimazole 1% cream, and triamcinolone 0.1% cream while oral ivermectin was required for eradication of scabies. For her superficial staphylococcal infection, she received 2 courses of cephalexin followed by prophylactic dosing with sulfamethoxazole/trimethoprim. She clinically improved with the above therapeutic regimens with subsequent yeast screens remaining negative.
