Early detection of neonatal cholestasis by stool color card screening

Area of Science:

• Neonatology
• Pediatric Gastroenterology
• Public Health Screening

Background:

• Neonatal cholestasis requires early detection to prevent severe liver damage.
• Biliary atresia is a primary concern, but other causes of cholestasis also necessitate prompt diagnosis.
• Stool color assessment is a non-invasive method for monitoring infant health.

Purpose of the Study:

• To evaluate the efficacy of early stool color screening in identifying infants with acholic or hypocholic stools.
• To detect biliary atresia and other causes of neonatal cholestasis in one-month-old infants.
• To assess the utility of a stool color card in a public health setting.

Main Methods:

• An observational, prospective study conducted from 1999 to 2002 in a public hospital in Argentina.
• Screening involved a stool color card assessment for all newborns attending their first-month checkup.
• A total of 12,484 infants were screened, with 4,239 specifically examined using the color card.

Main Results:

• Eighteen infants were identified with hypocholic stools.
• Out of these, only four infants were confirmed to have neonatal cholestasis.
• No cases of biliary atresia were detected during the study period.

Conclusions:

• Stool color card screening is a useful tool for detecting other causes of neonatal cholestasis beyond biliary atresia.
• While not detecting biliary atresia in this cohort, the method shows promise for broader neonatal cholestasis screening.
• Further research with larger sample sizes may be warranted to assess biliary atresia detection rates.
