A study (BL Schneider et al. J Pediatr 2016; 170: 211-7) from ChiLDReN (Childhood Liver Disease Research Network) shows that infants with biliary atresia whose total bilirubin (TB) does not drop below 2 mg/dL (34.2 microM) at anytime during the first 3 months after hepatoportoenterostomy (HPE) (Kasai) are at high risk for disease progression.
- 68/137 (50%) had TB <2.0 at some point following HPE.
- In the cohort with TB ≥ 2.0, the odds ratio for liver transplantation or death was 16.8. Higher TB was associated with diminished weight gain, coagulopathy, and hypoalbuminemia
- In the cohort with TB ≥ 2.0, transplant-free survival at 2 year occurred in only 20% compared with 86% in the TB <2.0 group
- Interestingly, only 6.6% had variceal bleeding among the entire cohort by age 2 years.
The TB was associated with multiple other parameters of worsening liver function, indicating that TB is not the only measure to affect the decision of liver transplantation.
My take: About half of all patients following a Kasai were at high risk for early progressive liver disease. TB ≥ 2.0 is a useful indicator of high risk.
