  • Publication number: 20260118348
    Abstract: A method is provided for prediction of risk for adverse clinical outcome in patients with compensated advanced chronic liver disease (cACLD) based on an oral distinguishable cholate challenge test (DuO oral distinguishable cholate liver function test).

  • Patent number: 12487231
    Abstract: A method for estimating portal blood flow and hepatic function in a subject is provided. In one example, the STAT test is an in vitro simplified, convenient test intended for screening purposes that can reasonably estimate the portal blood flow from a single blood sample taken 60 minutes after orally administered deuterated-cholate. The test can be administered to a patient having, or suspected of having, Chronic Hepatitis C, Primary Sclerosing Cholangitis (PSC), Non-Alcoholic Fatty Liver Disease (NAFLD), or any chronic liver disease.

  • Publication number: 20250264485
    Abstract: A Disease Severity Index (DSI) is provided for assessment of chronic liver disease in a patient using non-invasive liver function test results. A DSI was derived from non-invasive liver function test results based on hepatic blood flow. The DSI is used in methods for prediction of clinical outcomes, prediction of response to antiviral treatment, and assessment of progression of chronic liver diseases. Non-invasive methods to diagnose three distinct categories of patients with Primary Sclerosing Cholangitis (PSC) are provided. The methods can be used to diagnose PSC patients as Slow Progressors, Moderate Progressors and Rapid Progressors.

  • Publication number: 20240175881
    Abstract: Simplified methods are provided for determining liver function based on a Compartmental Model (CM) method for analysis of various hepatic indices including cholate SHUNT test which closely approximates and elucidates the underlying physiology of hepatic uptake of cholate from systemic and portal circulations simultaneously.
