BreathID 13C-Methacetin Breath Test for Detecting Cirrhosis

This trial is a pivotal trial to validate the use of a 13 C labeled substrate called methacetin and the BreathID automatic breath testing system, for determination of cirrhosis in patients with chronic liver disease.

About this study

Patients with chronic liver disease who have a recent biopsy will be offered a breath test. Correlation will be shown between histology and breath test in determining cirrhosis.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

  • Age >18 with chronic liver disease

Exclusion criteria

  • Patients that are taking hepatotoxin drug.
  • Patient with severe congestive heart failure
  • Patient with severe pulmonary hypertension
  • Patient with uncontrolled diabetes mellitus

Treatment and study plan

c13 methacetin solution with breath analyzer

Device

Carbon 13 methacetin 75mg dissolved in 150 ml is given to the subject and metabolism is measured by a breath analyzer after decomposed by the liver

Primary outcomes

  1. Number of Subjects With Likelihood of Cirrhosis Based on "Hepatic Impairment Score" (HIS)

    Time frame: Study day 1 after a 1 hour test

    "Hepatic Impairment Score" (HIS) is a score based on breath test parameters and demographic parameters of the subject being tested. A HIS value greater than 0.14 would mean that the subject is likely to be cirrhotic (based on biopsy result as the gold standard). The HIS is a probability score,i.e. ranges from 0 to 1, where 0 would mean the lowest probability of having liver cirrhosis and 1 would be the highest probability of having liver cirrhosis. This would be compared to the actual biopsy result of cirrhosis detection as the gold standard.

Secondary outcomes

  1. AUC of ROC (Area Under Receiver Operating Characteristic Curve)

    Time frame: At study day 1 after 1 hour test

    The AUC represents a summary measure of the ROC curve and is the accuracy of the HIS in detecting cirrhosis compared to the gold standard of biopsy.
