摘要 目的:探讨儿童嗜血细胞综合征(HPS)的临床特征及对预后有影响的危险因素。方法:回顾性分析54例儿童HPS的病因,临床特征,实验室检查结果及转归。结果:54例患儿均以发热为首要症状(100%),其余临床表现依次为脾脏肿大,肝脏肿大,淋巴结肿大,黄疸,多浆膜腔积液,水肿,呼吸系统症状,消化道出血,皮疹,泌尿系出血,中枢神经系统症状。实验室检查以肝功能异常最为突出(100%),其中以酶学(ALT、LDH、AST)改变为主(100%),次为低蛋白血症及高胆红素血症,之后依次为骨髓见噬血细胞,外周血至少两系细胞减少,高甘油三酯血症,血清铁蛋白升高,低纤维蛋白原血症,NK细胞活性降低,肾功能异常。病因分析显示:感染相关性(IAHS)占72.22%,以EB病毒相关性嗜血细胞综合征(EBV-AHS)最多,占IAHS的82.05%。54例HPS患儿中,自动出院19例,后经随访,16例死亡,接受治疗36例,接受治疗患儿中死亡9例(16.67%),痊愈22例(40.74%),5例正在治疗中。死亡25例(病死率46.29%)中,IAHS19例(其中EBV-AHS17例,败血症2例),恶性肿瘤2例,原因不明者4例。单因素分析显示:发病年龄、EBV感染、血小板计数降低、LDH和ALT水平升高与患儿死亡有关。将以上因素进行Logistic多因素分析显示:EBV感染、血小板降低、ALT升高是嗜血细胞综合征患儿死亡的独立危险因素。结论:HPS由多种病因所致,临床表现多样,预后凶险。EBV-AHS发病占首位,EBV感染、PLT计数、ALT水平是决定HPS预后的危险因素,确诊HPS后果断采用HLH-04方案治疗有助于提高HPS患儿的生存率。
