A Prospective Database of Infants With Cholestasis

This is a multi-center project to establish a prospective database of clinical information and a repository of blood, from children with diagnosis of neonatal liver disease, such as biliary atresia (BA), in order to perform research in this important liver problem. Children (diagnosed with BA or suspicious for BA) will be screened and enrolled at presentation at the participating pediatric liver sites. Participants diagnosed with BA will be followed intensively for the first year, at 18 months of age, and then annually up to 10 years of age, and then biannually, or liver transplantation. Other participants (Non-BA) diagnosed with cholestasis will be exited from the study at the time of diagnosis determination. Detailed clinical data, laboratory investigations, liver and biliary specimens, and long-term follow-up of outcomes are part of the normal standard of care with respect to the diagnosis and treatment of the subjects with liver problems. This research involves the collection of diagnostic, clinical and outcome data concerning the subject, which is kept without identification (coded) in a national research database of infants with liver disease. Samples of blood will be obtained for later research analysis, whenever possible, at the time of clinically indicated blood draws or when there is IV access for a clinical procedure. All data from this study will be kept in a secure research database at the Scientific Data Coordinating Center (SDCC) and transferred to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) data repository after the study ends.
