Full description

The purpose of this study is to validate the Disease Severity Index (DSI) from the HepQuant SHUNT Liver Diagnostic Kit (Test) for likelihood of large esophageal varices. The Hepatitis C Antiviral Long-term Treatment against Cirrhosis (HALT-C) Trial training dataset demonstrated that the DSI 18.3 had sensitivity 95%, specificity 54%, positive predictive value (PPV) 19%, negative predictive value (NPV) >99%, negative likelihood ratio (NLR) 0.09, and positive likelihood ratio (PLR) 2.09 for large varices. To validate DSI 18.3 as a cutoff for large varices, we will enroll 420 subjects with chronic liver disease (CLD) of mixed etiologies from 15 to 25 US clinical centers (CLD Validation dataset). The target prevalence of large varices is ≥20%. Each subject will have been scheduled for an esophago-gastro-duodenoscopy (EGD) as part of their standard of care for either variceal or non-variceal indications. Enrolled subjects will undergo standard clinical assessment, laboratory tests, and the HepQuant SHUNT Test. The EGD will be performed within 6 weeks following the HepQuant SHUNT Test. The relationship of DSI to large varices will be analyzed by univariate and multivariate logistic regression analyses, area under the receiver operating characteristic curve (AUROC), and linear and nonlinear regression and correlation coefficients. Diagnostic performance of the DSI cutoff will be defined in the CLD Validation dataset and validated for likelihood of large esophageal varices. The validated DSI cutoff will identify subjects who are either unlikely or likely to have large esophageal varices.
