Neonatal Cholestasis: Updates on Diagnostics, Therapeutics, and Prevention

Area of Science:

• Neonatology
• Hepatology
• Medical Genetics

Background:

• Cholestatic jaundice is a key indicator of liver dysfunction in infants.
• Timely diagnosis and evaluation are critical for effective treatment and improved infant outcomes.
• Genetic factors are increasingly recognized as causes of neonatal cholestasis.

Purpose of the Study:

• To review the causes, diagnostic approaches, and management strategies for cholestasis in infants.
• To highlight advancements in genetic diagnostics for neonatal cholestatic diseases.
• To discuss challenges and emerging therapies for neonatal cholestasis.

Main Methods:

• Review of current literature on neonatal cholestasis.
• Analysis of diagnostic advancements, including next-generation sequencing.
• Examination of therapeutic strategies and outcomes.

Main Results:

• Genetic sequencing offers rapid, cost-effective diagnosis for many previously unidentified cholestatic conditions.
• New lipid emulsions and infection control have reduced parenteral nutrition-associated liver disease.
• Biliary atresia diagnosis remains challenging, with delayed treatment impacting liver transplant rates.

Conclusions:

• Genetic sequencing has transformed the diagnosis of neonatal cholestasis.
• Despite progress, biliary atresia requires further research and improved early detection.
• Emerging therapies show promise for managing specific neonatal cholestatic disorders.
