| Abstract | Purpose of review: Cholestasis in infants can indicate a serious hepatobiliary disease and requires timely assessment, diagnosis and intervention to prevent progression to serious liver decompensation. This report aims to highlight recently published studies regarding diagnosis and treatment of cholestasis in infants. Recent findings: The evaluation of neonatal cholestasis can be challenging, requiring the assessment of a broad differential diagnosis in timely fashion. The Italian Society of pediatric gastroenterology, hepatology, and nutrition position paper on the evaluation of neonatal cholestasis is reviewed and compared to other published guidelines. In biliary atresia, the most time-sensitive of these diagnoses, serum matrix metalloproteinase-7 was studied in Japanese infants with biliary atresia with excellent diagnostic performance characteristics. Genetic testing panels are an increasingly used tool to help identify causes of cholestasis. An American experience of genetic testing in large cohort of infants identified a definite or possible genetic diagnosis in 11% of cholestatic infants. In the treatment of prutitus in Alagille syndrome and progressive familial intrahepatic cholestasis the clinical studies of two newly Food and Drug Administration approved ileal bile acid transport inhibitors are discussed. New information on the prevalence of cytomegalovirus and idiopathic cholestasis as other etiologies of infant cholestasis is also reviewed. Lastly, new insight on potential maternal microbiome regulation on biliary disease in neonates on experimental biliary atresia models is discussed. Summary: Cholestasis in infants requires timely diagnosis and intervention. There are exciting new diagnostic and treatment options now being studied which could help minimize the likelihood of advanced liver disease and development of serious complications. |
