Intestinal Failure-associated Liver Disease Clinical Trial
Official title:
A Prospective Prevalence Study in Adolescent and Adult Patients Dependent on Parenteral Nutrition to Assess the Incidence of Intestinal Failure-Associated Liver Disease
This is a multi-center prospective cross-sectional observational study that will assess the prevalence of liver disease in patients dependent on parenteral nutrition (PN) for 4 or more days per week. Liver disease will be determined by the presence of choline deficiency, cholestasis (confirmed by elevated serum alkaline phosphatase (ALP) liver isoenzyme level), and steatosis (confirmed by magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF). The objective of this study is to investigate the presence/prevalence of liver disease in patients dependent on PN (≥4 days a week).
Eligible participants will provide blood samples at Visit 1 to determine choline deficiency, elevated serum ALP liver isoenzyme level and liver dysfunction, and complete one imaging study (MRI-PDFF) at Visit 1 to assess steatosis. The purpose of this study is to understand and document critical epidemiological data related to choline deficiency and the incidence of liver disease in patients dependent on PN (≥ 4 days a week) and to better understand this patient population to help determine who might benefit from innovative treatments including IV Choline Chloride treatment. ;
