CHB is defined as conjugated bilirubin(CB) fraction greater than 15% of total bilirubin and CB greater or equal to 25 μmol/L. ECHB is defined as CHB detected within 14 d of life. "Late-onset" CHB(LCHB) is detected at 15-28 d of life and served as the comparison group.RESULTS Total of 117 patients were recruited: 65 had ECHB, 52had LCHB. Neonates with ECHB were more likely to be clinically unwell(80.0% vs 42.3%, P < 0.001) and associated with non-hepatic causes(73.8% vs 44.2%, P = 0.001) compared to LCHB. Multifactorial liver injury(75.0%) and sepsis(17.3%) were the most common causes of ECHB in clinically unwell infants, majority(87.5%) had resolution of CHB with no progression to chronic liver disease. Inborn errors of metabolism were rare(5.8%) but associated with high mortality(100%) in our series. In the subgroup of clinically well infants(n = 13) with ECHB, biliary atresia(BA) was the most common diagnosis(61.5%), all presented initially with normal stools and decline in total bilirubin but with persistent CHB. CONCLUSION Secondary hepatic injury is the most common reason for ECHB. BA presents with ECHB in well infants without classical symptoms of pale stools and deep jaundice.展开更多
目的分析高胆红素血症患儿新生儿溶血病(hemolytic disease of newborn,HDN)血清学检测结果并探讨与其相关因素之间的关系。方法对796例高胆红素血症患儿的血样进行新生儿溶血三项试验,并分析HDN阳性率与血型、送检日龄、血红蛋白水平...目的分析高胆红素血症患儿新生儿溶血病(hemolytic disease of newborn,HDN)血清学检测结果并探讨与其相关因素之间的关系。方法对796例高胆红素血症患儿的血样进行新生儿溶血三项试验,并分析HDN阳性率与血型、送检日龄、血红蛋白水平及血清总胆红素值等因素的关系。结果 796例高胆红素血症患儿中HDN患儿184例(23.12%),其中ABOHDN 176例,Rh-HDN 8例。796例患儿血样检测结果中游离试验阳性180例(22.61%),释放试验阳性184例(23.12%),直抗试验阳性140例(17.59%)。B型血患儿HDN阳性率高于A型血患儿,差异有统计学意义(χ2=10.30,P<0.05)。HDN阳性率与送检日龄密切相关,且日龄越大阳性检出率越低,差异有统计学意义(P<0.05)。184例HDN阳性患儿血红蛋白水平及血清总胆红素值与HDN患儿差异有统计学意义(P<0.05)。结论高胆红素血症患儿HDN阳性率较高,应尽早进行溶血三项试验,并可结合血红蛋白水平及血清总胆红素值来提高HDN检出率。展开更多
