    Abstract:
    BACKGROUND: The course of ulcerative colitis (UC) following orthotopic liver transplantation (OLT) for primary sclerosing cholangitis (PSC) is unclear. AIM: To investigate the clinical course of UC, before and after OLT for PSC. METHODS: From a historical cohort of 86 patients with PSC-UC who underwent OLT, 77 patients who were followed up at our institution both before and after OLT from 1985 to 2011 were included. RESULTS: Ulcerative colitis was diagnosed in 77 (97.5%) patients before OLT. Nineteen of 77 (24.7%) patients underwent colectomy before OLT. In the other 58 patients, the course of UC after OLT when compared to the last 5 years before OLT was quiescent in 48 patients (82.8%) while 9/58 (15.5%) of patients underwent colectomy post-OLT. There was a total of 97 colitis flares over a total of 621 years of follow-up from PSC/UC diagnosis to OLT (0.156 flares per patient year) whereas post-OLT, there were 31 flares over a total of 511 years of post-OLT follow-up (0.061 flares per patient year) (P < 0.001). On univariable analysis, the number of UC flares [Odds ratio (OR) 1.52; 95% Confidence interval (1.02-2.27), P = 0.04] and dysplasia [OR 47.00; 95% CI (6.48-340.66), P < 0.001] increased the risk of colectomy following OLT; the use of corticosteroids [OR 0.07; 95% CI (0.01-0.63), P = 0.008] and 5-aminosalicylate [OR 0.18; 95% CI (0.04-0.83), P = 0.04] was protective. CONCLUSIONS: Ulcerative colitis in the presence of primary sclerosing cholangitis remains quiescent, and may improve in most patients after orthotopic liver transplantation.
