Anti-integrin αvβ6 Autoantibodies Are Increased in Primary Sclerosing Cholangitis Patients With Concomitant Inflammatory Bowel Disease and Correlate With Liver Disease Severity.

ABSTRACT:

Background & aims

Anti-integrin αvβ6 autoantibodies (anti-αvβ6) are found in more than 50% of individuals with ulcerative colitis (UC). We aimed to determine the prevalence of anti-αvβ6 in patients with primary sclerosing cholangitis (PSC) and their association with liver disease severity.

Methods

Four cohorts of pre-liver transplant patients with PSC were recruited. Patients with inflammatory bowel disease (IBD) and healthy controls (HCs) served as comparators. Total IgG and anti-αvβ6 levels were measured using enzyme-linked immunosorbent assay. Olink inflammation panel was run on a subset of samples. Multivariable linear regression analysis was performed to assess the association between anti-αvβ6 and indices of liver disease severity.

Results

A total of 137 patient
