Abstract: BACKGROUND: Intensive intravenous treatment remains the first line therapy of severe, uncomplicated attacks of ulcerative colitis. AIM: To predict the failure of intensive intravenous treatment by combining clinical and laboratory parameters with endoscopy findings. METHODS: Retrospective study conducted in a tertiary care referral centre. Failure of intensive intravenous treatment was defined as colectomy before day 30, intravenous cyclosporin, or death. Predictive factors of outcome were assessed using univariate and multivariate prognostic analysis. RESULTS: Between January 1990 and May 1997, 85 consecutive patients were treated with intensive intravenous treatment for non-response to oral corticosteroids (n=59) and/or severe attack of ulcerative colitis (n=26). There were 41 successes and 44 failures (including 1 death, 13 cyclosporin and 30 colectomies before day 30). Multivariate prognostic analysis found that the presence of Truelove and Witts' criteria (P=0.018), an attack that had lasted more than 6 weeks (P=0.001), and severe endoscopic lesions (P=0.007) were associated with an increased risk of failure. Patients with severe endoscopic lesions and Truelove and Witts' criteria, or an attack of more than 6 weeks had a failure rate of 85-86%. CONCLUSION: Clinical, laboratory and endoscopic findings can predict the risk of failure of intensive intravenous treatment. A prospective study is required to confirm these results.

Abstract: AIM: To determine whether prior appendectomy modifies the phenotype and severity of Crohn's disease. METHODS: Appendectomy status and smoking habits were specified by direct interview in 2838 patients consecutively seen between 1995 and 2004. Occurrence of complications and therapeutic needs were reviewed retrospectively. Additionally, annual disease activity was assessed prospectively between 1995 and 2004 in patients who had not had ileocecal resection and of a matched control group. RESULTS: Compared to 1770 non-appendectomized patients, appendectomized patients more than 5 years before Crohn's disease diagnosis (n=716) were more often females, smokers, with ileal disease. Cox regression showed that prior appendectomy was positively related to the risk of intestinal stricture (adjusted hazard ratio, 1.24; 95% confidence interval, 1.13 to 1.36; P=0.02) and inversely related to the risk of perianal fistulization (adjusted hazard ratio, 0.75; 95% confidence interval, 0.68 to 0.83; P=0.002). No difference was observed between the two groups regarding the therapeutic needs, except for an increased risk of surgery in appendectomized patients, attributable to the increased prevalence of ileal disease. Between 1995 and 2004, Crohn's disease was active during 50% of years in appendectomized patients (1318 out of 2637 patient-years) and 51% in non-appendectomized patients (1454 out of 2841 patient-years; NS). CONCLUSION: Prior appendectomy is associated with a more proximal disease and has an increased risk of stricture and a lesser risk of anal fistulization. However, the severity of the disease is unaffected.

Abstract: BACKGROUND AND AIMS: The aim of this study was to examine in parallel the effect of smoking on ulcerative colitis and Crohn's colitis and assess the effect of gender on the response of colitis to smoking. METHODS: Medical charts of 1784 adult consecutive patients (978 patients, ulcerative colitis; 118 patients, indeterminate colitis; and 688 patients, Crohn's colitis), whose smoking habits were specified by direct interview, were reviewed. RESULTS: The proportion of ever smokers was 42% in ulcerative colitis, 43% in indeterminate colitis, and 61% in Crohn's colitis. Smoking cessation preceded the onset of colitis in 279 patients with ulcerative colitis or indeterminate colitis (61%) and only 52 patients (12%) with Crohn's colitis. In ulcerative colitis and indeterminate colitis, current smoking delayed mean age at disease onset in men (from 32 to 41 yr; P < 0.001), but not women (from 33 to 33 yr), and decreased the need for immunosuppressants in men (10-yr cumulative risk, 26% +/- 4% in nonsmokers vs. 8% +/- 4% in smokers; P < 0.01), but not significantly in women. Conversely, in Crohn's colitis, current smoking hastened disease onset in women (from 35 to 29 yr; P < 0.001), but not men (from 32 to 31 yr), and increased the need for immunosuppressants in women (10-yr cumulative risk, 48% +/- 5% in nonsmokers vs. 58% +/- 4% in smokers; P < 0.01), but not men. CONCLUSIONS: The dual effects of smoking in colitis, beneficial in ulcerative colitis and harmful in Crohn's colitis, are modulated importantly by gender, with women having more disadvantage than men.

Abstract: BACKGROUND: Appendicectomy reduces the risk of having ulcerative colitis. However, its effect on the natural history of ulcerative colitis remains uncertain. AIM: To determine whether appendicectomy reduces the overall severity of ulcerative colitis. PATIENTS AND METHODS: Appendicectomy status and smoking habits were specified by direct interview in 638 patients seen consecutively between 1997 and 2000. Severity of ulcerative colitis was assessed by reviewing therapeutic needs from the onset of colitis. Additionally, the annual incidence of flare up was assessed prospectively between 1997 and 2000 in patients who had not been colectomised. RESULTS: The 10 year risk of colectomy was 16 (7)% in previously appendicectomised patients (n=49) compared with 33 (2)% in non-appendicectomised patients (n=589, p=0.05). Cox regression showed that previous appendicectomy and current smoking were independent factors protecting against colectomy (adjusted hazard ratio and 95% confidence intervals: 0.40 (0.20-0.78) and 0.60 (0.40-0.95), respectively). The respective proportions of appendicectomised and non-appendicectomised patients who required oral steroids and immunosuppressive therapy were not significantly different (67% v 70% and 27% v 19%, respectively). Between 1997 and 2000, ulcerative colitis was active for 48% of the time in appendicectomised patients (47 of 98 patient years) and for 62% of the time in non-appendicectomised patients (631 of 1024 patient years; p<0.01). CONCLUSION: Previous appendicectomy is associated with a less severe course of ulcerative colitis. The beneficial effect of appendicectomy on the risk of colectomy is additive to that of current smoking.

Abstract: OBJECTIVES: The incidence and severity of ulcerative colitis (UC) are higher in nonsmokers than in smokers. The natural course of UC in smokers who stop smoking is not known. The aim of this study was to determine the impact of cessation of smoking on the course of UC among the cohort of patients regularly seen at our institution. METHODS: The severity of UC, as judged by the occurrence of flare-ups and the need for systemic steroids, immunosuppressive drugs and colectomy, was determined in 32 patients with UC who stopped smoking after the diagnosis of UC. We compared the period after cessation of smoking (7-yr mean follow-up) with the period between the onset of the disease and the cessation of smoking (9-yr mean duration). The course of UC in this group was compared with that of 32 nonsmokers and 32 continuing smokers matched for sex, age, and age at onset. RESULTS: In patients who quit, cessation of smoking was followed by an increase in the rate of years with active disease (p < 0.01), years with hospitalization (p < 0.05) and years with major medical therapy (oral steroids, intravenous steroids, and azathioprine, p < 0.01). After cessation of smoking, the rate of years with immunosuppressive therapy was significantly greater in ex-smokers and nonsmokers than in continuing smokers (p < 0.01). The risk of colectomy in ex-smokers after smoking cessation was similar to that of nonsmokers and continuing smokers. CONCLUSIONS: In smokers with UC who stop smoking, the severity of the disease increases after smoking cessation, with an increase in the disease activity and the need for hospital admission and major medical therapy. In addition, the need for azathioprine therapy becomes similar to that of nonsmokers.
