Ability of different rescue therapies to save the bowel in acute, severe, steroid-refractory ulcerative colitis

Short-term colectomy is avoided in over half of regional patients failing medical therapy for acute severe ulcerative colitis with co-ordinated transfer and tertiary care

BACKGROUND AND AIMS

Many patients presenting with an acute severe ulcerative colitis to a regional hospital are transferred to a metropolitan hospital for specialised care. This study aimed to evaluate the outcomes and characteristics of these patients.

METHOD

A retrospective observational cohort study was conducted to examine the 30-day colectomy rate using prospectively collected data on 69 consecutive index cases of acute severe ulcerative colitis transferred from regional hospitals to our metropolitan hospital meeting Truelove and Witts criteria. Those that avoided colectomy were followed out to 1 year to examine outcomes.

RESULTS

The 30-day colectomy rate was 46.4% (32/69) in regional transfer patients. Rescue therapy was administered to 65% (45/69) of patients after transfer to our metropolitan hospital. Colectomy was avoided in 55% of these patients at 30 days. Colectomy free status was maintained in 78% (29/39) of these patients. Mortality was 0% at 30 days and 1 year.

CONCLUSION

Over 50% of the patients failing therapy in a regional centre and requiring transfer avoided short term colectomy with co-ordinated referral for rescue therapy in a tertiary metropolitan inflammatory bowel disease unit. These patients would have ultimately required colectomy in their regional hospital without intervention.

Colectomy rates in patients with ulcerative colitis following treatment with infliximab or ciclosporin: a systematic literature review

This review aimed to compile all available published data on colectomy rates following treatment using infliximab or ciclosporin in adult ulcerative colitis patients and to analyse colectomy rates, timing to colectomy and postcolectomy mortality for each treatment. We systematically reviewed the literature after 1990 reporting colectomy rates in ulcerative colitis patients treated with infliximab or ciclosporin, excluding articles on paediatric patients, patients with indeterminate colitis or Crohn's disease and bowel surgery not related to ulcerative colitis. We presented weighted mean colectomy rates and mortality rates. Cox's regression was used to assess time to colectomy adjusting for colitis severity, patient age and sex. We tabulated 78 studies reporting on ciclosporin and/or infliximab and colectomy rates or postcolectomy mortality rates. Not all studies reported data in a standardized manner. Infliximab had a significantly lower colectomy rate than ciclosporin at 36 months when analysing all studies, studies directly comparing infliximab and ciclosporin and studies using severe colitis patients, but not at 3, 12 or 24 months. Severity and age were key indicators in the likelihood of undergoing colectomy after treatment. Postcolectomy mortality rates were less than 1.5% for both drugs. This review indicates that long-term colectomy rates following infliximab are significantly lower than ciclosporin in the longer term, and that postcolectomy mortality following infliximab and ciclosporin is very low. However, many key data items were missing from research articles, reducing our ability to establish with more confidence the actual impact of these two drugs on colectomy rates and postcolectomy mortality rates.

Pharmacologic therapy for inflammatory bowel disease refractory to steroids

Although corticosteroids are an effective treatment for induction of remission in inflammatory bowel disease (IBD), many patients are dependent on or refractory to corticosteroids. This review is based on scrutinizing current literature with emphasis on randomized controlled trials, meta-analyses, and Cochrane reviews on the management of IBD refractory to corticosteroids. Based on this evidence, we propose algorithms and optimization strategies for use of immunomodulator and biologic therapy in IBD refractory to corticosteroids.
