Anti-integrin αvβ6 Antibodies Predict Pouchitis in Patients With Ulcerative Colitis After Restorative Proctocolectomy With Ileal Pouch-Anal Anastomosis.

ABSTRACT:

Background

Pouchitis is the most common complication of restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). We previously reported the presence of anti-integrin αvβ6 antibodies in the serum of patients with UC. This study investigated the association between anti-integrin αvβ6 antibodies and the development of pouchitis in patients with UC.

Methods

Serum levels of anti-integrin αvβ6 antibodies were measured by enzyme-linked immunosorbent assay in 16 patients with UC who underwent RPC with IPAA. Integrin αvβ6 expression in the colonic, terminal ileal, and pouch epithelium was examined using immunohistochemistry and western blot analysis.

Results

Anti-integrin αvβ6 antibody levels in patients with UC were
