A2 - Sunshine, Philip PY - 2015 T2 - Neonatology: Clinical Practice and Procedures AB - Historical estimates place the incidence of cholestasis among all neonates at 1 in 2500 live births.1 A recent retrospective data review found that among all infants cared for in a large hospital system in the United States who had at least 1 measured conjugated bilirubin level, 3 in 1000 had a peak conjugated (direct) bilirubin greater than 2.0 mg/dL2; however, in the majority of these patients a specific hepatobiliary disorder was not identified, and the peak bilirubin was relatively low ( 1.0 mg/dL when total bilirubin is 5 mg or less or direct bilirubin > 20% of total bilirubin when the total bilirubin is above 5 mg/dL) was identified in 2% of all NICU patients.3 Risk factors that are common in this population include prematurity, low birth weight, sepsis, shock, surgery, and parenteral nutrition.4 Thus, although cholestatic liver disease is rare in general outpatient pediatrics, the neonatologist must be familiar with the initial triage and diagnostic evaluation, as well as supportive care, of the cholestatic infant.
