This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This completed study looked at whether fragments from gut bacteria (called peptidoglycans) are linked to alcohol-related liver disease. 40 participants with liver cirrhosis provided stool samples to measure these fragments. The goal was to see if these fragments could be used as a screening or diagnostic tool for the disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could point toward new ways to screen for or diagnose alcohol-related liver disease using stool samples.
What could go wrong
This is a small, completed observational study (40 people) that only looks for a link, not a treatment. The findings may not apply to everyone with the disease.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: (1) patients diagnosed with liver cirrhosis based on clinical-pathologic features including liver history and endoscopic or radiologic findings (the presence of clinical cirrhosis was adjudicated in a blinded fashion by two separate hepatology experts; to be included, both experts were required to agree on the presence of clinical cirrhosis) and (2) all patients with chronic liver disease were required to have evidence of clinical liver disease for at least 6 months and were required to have an identifiable etiology of liver disease, including alcohol-related liver diseases (based on a history of alcohol use disorder or a past history of alcohol consumption of greater than 2 ounces of ethanol per day for men or 1 ounce of ethanol per day for women (for greater than 10 years) with no other cause of liver disease identified), NAFLDs, viral hepatitis B or C (detected by HCV RNA or HBV DNA measurement) or autoimmune liver disease (based on international autoimmune scoring criteria). Exclusion Criteria: (1) individuals treated with antibiotics, probiotics or proton pump inhibitors within 1 month before sample collection; (2) any participant undergoing a gastrointestinal surgical procedure or colonoscopy within 6 months before sample collection; (3) any individual with uncontrolled infection; and (4) individuals with uncontrolled systolic blood pressure.
