摘要: 目的 探讨尿液生物学标志物在儿童巨细胞病毒(CMV)感染所致肾损伤以及治疗前后的变化。方法 收集我科 CMV 感染的患儿 50 例作为患儿组, 对照组选择健康体检儿童 35 例, 患儿组在入院初检测血肌酐 (Scr)、 血尿素氮 (BUN)、 血β2微球蛋白 (MG)、 肝功能、 血 CMV-IgM, 血及尿液 CMV-PCR、 脑干电测听(BAEP)、 头 CT、 尿常规,尿液中的尿液转铁蛋白(TFR)、 微量白蛋白(mALb)、 β2MGα1MG N-乙酰-β-D 氨基葡萄糖苷酶(NAG), 合并 MV肺炎吸取痰液检测 CMV-PCR。所有患儿均给予更昔洛韦治疗, 5 mg/kg 加入 0.9%氯化钠溶液(5 mL/kg)中, 静脉滴注12 h 1 次, 每次滴注不少于 1 h, 持续 14 d, 复查尿液 TFRmALbβ2MGα1MG NAG结果 患儿组与对照组尿mALbTFR 差异无统计学意义, 患儿组尿液α1MGNAGβ2MG 高于对照组, 患儿组予更昔洛韦抗病毒治疗 2 后, 复查尿液α1MGNAGβ2MG 治疗后较治疗前降低, 而尿液 mALbTFR 治疗前后差异无统计学意义。结论 尿液β2MGα1MGNAG 的联合检测对于早期发现儿童 CMV 肾损害有很好的提示作用。

Abstract: Objective To explore changes of urine transferrin (TFR)micro albumin (mALb), β2 microspheres protein (MG), α1MG and N- acetyl β-D amino group (NAG) in children with kidney injury induced by cytomegalovirus (CMV) infection, and the outcome after treatment. Methods Fifty children with CMV infection were used as case group, and 35 children of convalescence stage of upper respiratory tract infection were used as control group. The serum levels of creatinine (Scr), blood urea nitrogen (BUN), β2MG, liver function, CMV-IgM, CMV-PCR and brainstem auditory (BAEP), head CT and urine routine test, urine TFR, mALb, β2MG, α2MG and NAG were detected. The sputum CMV-PCR was detected if children combined with CMV pneumonia. Ganciclovir (5mg/kg) was given to two groups, 1/12 h i.v. for 14 d. The urine TFRmALb, β2MG, α2MG and NAG were detected again after treatment. Results There were no significant differences in the urine mALb and TFR between the two groups. The urine levels of α1MG, NAG and β2MG were higher in case group than those of control group. The urine levels of α1MG, NAG and β2MG were decreased after 2-week treatment in case group. There were no significant differences in urine mALb and TFR before and after treatment. Conclusion The combined detection of β2MG, α1MG and NAG can predict CMV kidney damage in children at a early stage.
