Risk factors and inflammatory markers in pouchitis
Abstract
Individuals who do not respond to medical therapy for ulcerative colitis (UC) often undergo proctocolectomy followed by ileal-pouch anal anastomosis (IPAA) in hopes of resolving symptoms associated with UC. Inflammation of the ileal pouch, better known as pouchitis, is the most common complication of the IPAA procedure. The causes and development of pouchitis is not well understood. To better understand pathogenesis of pouchitis, pouch aspirates of patients having undergone IPAA were quantitatively analyzed for fecal IL-8, IL-17, and IL-23 levels. According to published literature IL-8 has been linked to pouchitis whereas IL-17 and IL-23 are associated with intestinal inflammation. The study had 80 participants, 33 patients diagnosed with Crohn's Disease (CD) of the pouch, 19 patients diagnosed with pouchitis, and 28 diagnosed with having normal pouches. Patient characteristics and histopathological findings for all patients were noted and statistically compared in addition to fecal cytokine levels. This study supported previous literature that IL-8 production was associated with pouch inflammation. However, IL-17 and IL-23 levels in both CD of the pouch and pouchitis were not significantly different to the levels noted in normal pouch.
