Cirrhosis

Cirrhosis is scarring (fibrosis) of the liver caused by long-term liver damage. The scar tissue prevents the liver from working properly. Professor Alastair O'Brien’s team conducts large-scale clinical trials, feasibility studies and data analyses to try to improve outcomes in people with cirrhosis.

Our work

Cirrhosis is the impaired liver function caused when scar tissue formed after liver disease gradually replaces normal functioning tissue. It can take years to develop.

Cirrhosis is often caused by alcoholic liver disease, heroin use, and chronic hepatitis B / C. Non-alcoholic steatohepatitis (NASH) can be caused by obesity, high blood pressure or cholesterol, type 2 diabetes, and metabolic syndrome.

It causes an array of symptoms, from fatigue, nausea and stomach pain, to swelling, jaundice and infections from fluid that collects in the abdomen. In serious cases, it can cause bleeding from swollen veins, or even liver cancer.

We completed the national ATTIRE trial (Albumin to prevent infection in chronic liver failure), and our ASEPTIC trial (Primary Antibiotic Prophylaxis using Cotrimoxazole to Prevent Spontaneous Bacterial Peritonitis in Cirrhosis) is now in the follow-up phase.

Professor O’Brien is also the Clinical Director of the UCL Comprehensive Clinical Trials Unit.
