Abstract

Atypical perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) have been detected in most patients with ulcerative colitis and primary sclerosing cholangitis. Persistent atypical p-ANCA have been observed in ulcerative colitis patients with a prior proctocolectomy, especially with pouchitis, suggesting that this serological marker might be predictive of subsequent development of chronic or refractory pouchitis. This study prospectively evaluated this serological marker in 24 consecutive patients with inflammatory bowel disease and prior colectomies (12 with a clinical diagnosis of ulcerative colitis and 12 with a clinical diagnosis of Crohn's disease involving the colon). Of these, 14 were positive, including 11 with extensive ulcerative colitis and three with Crohn's disease. Although two of three ulcerative colitis patients with pouchitis were positive, eight of eight ulcerative colitis patients having a pelvic pouch with no pouchitis were also positive, as was a patient who elected to have an end-ileostomy (Brooke's ileostomy). Two patients had abnormal liver chemistry tests. Both had end-stage primary sclerosing cholangitis treated with liver transplantation and were positive for this serological marker. Although atypical p-ANCA may be a marker of persistent inflammation in pelvic pouch patients, a positive test result should not be used for prognosis or as a decision-making parameter for pelvic pouch procedures.
