To determine the prognostic value of indirect and direct hyperbilirubinemia in neonates with jaundice.
A cohort of 92 consecutive neonates reporting with hyperbilirubinemia to a tertiary care center were followed up till well and discharged, or, till death to assess risk and rate of mortality.
The baseline median values of total, direct and indirect bilirubin in the cohort of 21.8, 1.6 and 18.6 mg/dl, respectively, were used as cut-offs for high and low levels. Using survival analyses i.e. Kaplan-Meier plots, logrank tests and multivariate Cox proportional hazards regression models to adjust for other strong predictors such as receipt of breastfeeding, being small for gestational age (SGA) and exchange transfusion, high direct bilirubin (> or = median value of 1.6 mg/dl) was independently associated with a higher and faster mortality.
This study showed that direct bilirubin has independent and additive prognostic value and due attention should be given to newborns with raised levels.
确定间接和直接高胆红素血症在新生儿黄疸中的预后价值。
对一家三级护理中心连续收治的92例高胆红素血症新生儿进行随访,直至康复出院或死亡,以评估死亡风险和死亡率。
该队列中总胆红素、直接胆红素和间接胆红素的基线中位数分别为21.8、1.6和18.6mg/dl,用作高低水平的分界值。采用生存分析,即Kaplan-Meier曲线、对数秩检验和多变量Cox比例风险回归模型,以调整其他强预测因素,如母乳喂养、小于胎龄儿(SGA)和换血治疗,高直接胆红素(>或=中位数1.6mg/dl)与更高、更快的死亡率独立相关。
本研究表明,直接胆红素具有独立且累加的预后价值,对于直接胆红素水平升高的新生儿应给予充分关注。
