HepQuant tests are new liver tests that are being developed to accurately measure liver function with sensitivity and specificity while being safe and non-invasive. The primary goal of this study is to define the intra-individual reproducibility of the HepQuant tests, that is, to see if a person is given the tests several times that the test results are essentially the same each time. Subjects for this study will include healthy controls and patients with chronic liver diseases. The chronic liver diseases will include hepatitis C virus (HCV) infection and a serious form of fatty liver disease, known as non-alcoholic steatohepatitis (NASH). The HCV and NASH patients will include men and women, and those with early stage and late stage liver disease as defined by the amount of fibrosis observed in their liver biopsies. Once a subject has been enrolled in the study they will be given the HepQuant tests on three separate days within the span of one month. The hypothesis of this study is that HepQuant tests will reproducibly report liver function in healthy controls and patients with all stages of chronic HCV and NASH liver disease and that liver function will decrease as the amount of liver fibrosis increases in the chronic liver disease patients.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Cholate Shunt Test | The Cholate Shunt Test result is defined as the ratio of the IV Cholate Clearance to the Oral Cholate Clearance and is expressed as a percentage. The higher the SHUNT percentage, the more the blood flow is shunting around the liver, the more severe the liver disease. The average of the SHUNT test results (ratio of IV Cholate Clearance to Oral Cholate Clearance) from all three time points (3 visits within 30 days) for each participant was used in the calculation of the group SHUNT Test results. |
Average of all three study visits performed within 30 days | |
Secondary | Intra-individual Reproducibility of the Cholate SHUNT Test Across All Subjects | The intra-individual reproducibility of the Cholate Shunt Test (SHUNT %), will be defined by its average Coefficient of Variation (CV) and its Intra-Class Correlation (ICC). Each subject will be tested at baseline and then twice more on separate days within the span of one month. The CV of each subject's three replicate tests will be used to calculate the average CV for each type of test. All test results for each type of test will be used to calculate its ICC. | All three study visits within 30 days | |
Secondary | Intra-class Reproducibility of the Disease Severity Index (DSI) by Histological Fibrosis Stage | The intra-class correlation coefficients (ICCs) for reproducibility of the Disease Severity Index (DSI, an index value measuring severity of liver disease that can be calculated using the SHUNT Test results) were obtained by stage of liver fibrosis by liver biopsy. The DSI is a score on a scale from 0 (healthy) to 50 (severe liver disease), so the higher the DSI, the more severe the liver disease. Fibrosis scores increase with disease severity as well, so subjects with F0-F2 fibrosis have less severe liver disease than subjects with F3-F4 fibrosis. |
Average of DSIs obtained from all three study visits within 30 days |
