Blood:噬血细胞性淋巴组织细胞增多症成年患者的诊疗

2019-04-18 MedSci MedSci原创

噬血细胞性淋巴组织细胞增多症(HLH)是由异常活化的巨噬细胞和细胞毒性T细胞导致的一种严重的炎症综合征。由影响淋巴细胞毒性和免疫调节的突变引发的原发性(遗传型)HLH最常见于儿童,而继发性(获得性)HLH最常见于成年人。继发性HLH继发于炎症或恶性肿瘤,但也可由自身炎症/自身免疫性疾病引起;由自身免疫引发的HLH又称为巨噬细胞活化综合征(MAS或MAS-HLH)。HLH诊疗的大部分信息都是来自与儿

噬血细胞性淋巴组织细胞增多症(HLH)是由异常活化的巨噬细胞和细胞毒性T细胞导致的一种严重的炎症综合征。由影响淋巴细胞毒性和免疫调节的突变引发的原发性(遗传型)HLH最常见于儿童,而继发性(获得性)HLH最常见于成年人。

继发性HLH继发于炎症或恶性肿瘤,但也可由自身炎症/自身免疫性疾病引起;由自身免疫引发的HLH又称为巨噬细胞活化综合征(MAS或MAS-HLH)。

HLH诊疗的大部分信息都是来自与儿科文献。虽然也可用于部分成年患者,但仍有很多不足。例如,针对儿童的2004版HLH诊断标准应用最广,但并不适用于成年患者。HLH诊断的另一个挑战是,患者可能会出现与败血症或多器官功能障碍综合征(MODS)难以区分的表型。针对超级炎症的治疗算法往往都是基于儿科的治疗方案,如94版HLH和2004版HLH,应用与成年患者时,可能会导致过度治疗和不必要的毒性。

因此,应考虑对剂量和治疗时间进行个体化调整,根据年龄修正诊断方法。为提高HLH成年患者的预后,多位专家共同商议建立针对成人HLH患者特异性的诊疗标准,意见详见正文。

Lancet:这名患者的诊断扑朔迷离,你能诊断正确吗?——案例报道

患者女,32岁,腰背疼痛、大腿沉重、间歇性发热和寒战2周。 既往史包括三叉神经痛、焦虑(近期服用奎硫平)。 查体:体温39°C,余正常。 实验室检查:C-反应蛋白升高(CRP; 118 mg/L),包括肝功能、肾功能在内的生化指标和其他血常规指标都未见明显异常。 考虑急性肾盂肾炎,予以广谱抗生素治疗;但患者的血培养、尿培养均是无菌的,泌尿系统CT也是正常的,于是停止了抗生素
