摘要 目的了解新生儿高胆红素血症对肾功能的影响以及测定血β2微球蛋白的临床意义。方法对79例高胆红素血症和43例非高胆红素血症的新生儿进行血尿素氮、肌酐和β2微球蛋白测定。结果高胆组和非高胆组新生儿血尿素氮、肌酐值均在正常范围,两组比较差异无统计学意义(P均>0.05);高胆组血β2微球蛋白浓度(4.06±0.73)mg/L高于非高胆组(2.01±0.76)mg/L,差异有高度统计学意义(P<0.001);中度高胆组(4.52±0.35)mg/L和轻度高胆组(3.35±0.41)mg/L比较差异有高度统计学意义(P<0.001),重度高胆组(4.75±0.30)mg/L和中度高胆组比较差异有统计学意义(P<0.05);血胆红素水平与血β2微球蛋白浓度经线形相关分析呈高度直线正相关(r=0.86,P<0.001)。结论新生儿高胆红素血症时β2微球蛋白明显增高,存在肾小球滤过率的下降,并随着血胆红素浓度的增加而加剧,血尿素氮、肌酐不能反映此种变化;对新生儿高胆红素血症应予以积极干预并避免使用肾毒性药物,以免加重肾脏损害。
