Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory disease with relapses. Many patients need systemic corticosteroids to induce clinical remission. AIM Efficacy and safety of Budesonide-MMX® 9 mg tablets, a new oral, extended-release formulation, were evaluated in patients suffering from active, left-sided UC with colitis activity index (CAI) <14. METHODS 36 patients were treated once daily for 4 weeks with Budesonide-MMX® 9 mg tablets or placebo. In an additional 4-week period, all patients received Budesonide-MMX®. CAI, endoscopic index and histology were assessed after 4 and 8 weeks. Primary end-point was remission, and/or CAI reduction by 50% after 4 weeks. Morning cortisol was assayed after 4 and 8 weeks, and a short ACTH-test was performed at week 8. RESULTS 32 patients were analysed. After 4 weeks, 47.1% of the patients in the Budesonide-MMX® 9 mg tablets group achieved the primary end-point vs. 33.3% of patients on placebo. In addition, 47.1% of budesonide patients and another 33.3% of placebo recipients improved without remission by 4 weeks. The CAI reduction was significant with Budesonide (p<0.0001) tablets and not with placebo (p=0.1). Neither morning cortisol nor pituitary-adrenal axis was more frequently suppressed with Budesonide tablets than with placebo. CONCLUSIONS Budesonide-MMX® 9 mg tablets induced a fast and significant clinical improvement of active left-sided UC without suppression of adrenocortical functions and without important toxicity EudraCT number 2004-000896-33.

Abstract
BACKGROUND/AIM To investigate patient-reported health-related quality of life (HRQoL) in data collected from a multinational randomized double-blind controlled trial comparing oral mesalazine (4 g) + topical mesalazine enema (1 g) to oral mesalazine alone (4 g). METHODS HRQoL was collected using the EQ-5D at baseline and weeks 2, 4 and 8. The EQ-5D assesses mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Scores from each dimension were reported individually, and converted into a weighted health state which reflects an individual's perception of their health condition. RESULTS At week 4, a significant HRQoL improvement was observed for patients on mesalazine enemas compared to placebo enemas, with EQ-5D scores of 0.906 and 0.838, respectively (p < 0.05). Mesalazine enema was found to reduce the probability of impairment at week 4 for mobility (p = 0.049) and anxiety/depression (p = 0.048), and was of borderline significance for pain/discomfort (p = 0.053); there was also an increased probability of influencing HRQoL changes for mobility (p < 0.005), usual activities (p < 0.005), pain/discomfort (p < 0.005) and anxiety/depression (p < 0.005), based on reported HRQoL problems at baseline. CONCLUSIONS Including 1 g mesalazine enemas with 4 g oral mesalazine significantly improved HRQoL in patients with active ulcerative colitis. The improvement in QoL of patients with UC preceded clinical remission, and this underlines the importance of including QoL instruments in clinical studies.

Abstract
The pathogenesis of inflammatory bowel disease (IBD) involves an interaction between host susceptibility (which is partly genetically determined), mucosal immunity and the intestinal milieu. Micro-organisms have physiological effects on mucosal structure, epithelial turnover, the intestinal immune cells and, thus, on many intestinal functions. Toll-like receptors and nucleotide oligomerisation-binding domain proteins in host cells recognise specific bacterial molecules and modify the immune response. Human studies have repeatedly shown that the microbiota of patients with IBD differs from that of controls and is unstable, both in the intestinal lumen and at the surface of the mucosa. A single pathogen has not been identified, but potentially pro-inflammatory micro-organisms have been found in samples from IBD patients more often than from healthy controls. These include Mycobacterium paratuberculosis, and enteroadherent and invasive Escherichia coli in Crohn's disease (CD). Ecological descriptions of the microbiota present in patients with IBD (either in the faeces or adherent to the mucosa) have repeatedly reported a decrease in usually dominant bacteria, especially those from the dominant phylum Firmicutes. A decrease in the biodiversity of Firmicutes has been observed in CD, while a recent study has shown that a decrease in Firmicutes, especially Faecalibacterium prausnitzii, was associated with CD and the post-operative recurrence of CD lesions in the ileum. Taken together, these results suggest that dysbiosis, or an imbalance within the (dominant) intestinal microbiota, may favour IBD.

Abstract
AIM To evaluate whether crypt abscesses from inflammatory bowel disease (IBD) patients contain bacteria and to establish their nature. METHODS We studied 17 ulcerative colitis patients, 11 Crohn's disease patients, 7 patients with acute self-limited colitis (ASLC) and normal colonic biopsies from 5 subjects who underwent colonoscopy for colon cancer screening. A fluorescent in situ hybridization technique was applied to colonic biopsies to assess the microbiota composition of the crypts and crypt abscesses. RESULTS Crypts colonized by bacteria were observed in 42.9% and 3.6% of ASLC and IBD patients, respectively (P = 0.019). Crypt abscesses colonized by bacteria were observed in 28.6% and 0.0% of ASLC and IBD patients, respectively (P = 0.035). CONCLUSION These results do not support the hypothesis that crypt abscesses in IBD are the result of localized dysbiosis arising from persistence of living bacteria colonizing the crypts.

Abstract
BACKGROUND AND AIM The prevalence and incidence of inflammatory bowel disease (IBD) differs worldwide. While the prevalence of IBD has stabilized in Europe, the USA and Japan, an increasing trend has been observed in Asia. However, there are no data on the current clinical practice for the management of IBD in the region. The present study aims to investigate the number of existing and new cases of IBD and to understand the current practice of diagnosis and treatment of IBD in different Asian countries. METHODS A self-administered questionnaire, designed according to European and US guidelines, was distributed to IBD specialists throughout Asia. The questionnaire estimated the annual incidence of existing and new IBD cases in physicians' clinical practices and evaluated their procedures of diagnosis and preference for therapeutic treatment and maintenance treatment. RESULTS Eighty-seven questionnaires were received out of the 107 distributed. In the clinical practices of these 87 respondents, there were 502 existing and 73 new cases per year for ulcerative colitis (UC) and 202 existing and 32 new cases per year for Crohn's disease (CD). Colonoscopy and histology were the most commonly used methods for the diagnosis of UC and CD, but clinical practice regarding the diagnosis of IBD varied. The treatment of choice for mild-to-moderate UC and CD was 5-aminosalicylic acid (5-ASA), which is also the preferred choice for the maintenance treatment of UC and CD. CONCLUSION Clinical practice with regards to IBD diagnosis and management varies within Asia.5-ASA is the preferred treatment and maintenance therapy for mild-to-moderate IBD.

Abstract
BACKGROUND Adalimumab (ADA) and certolizumab pegol (CZP) have demonstrated efficacy in Crohn's disease (CD) patients previously treated with infliximab (IFX). AIM To assess the efficacy and tolerability of a third anti-TNF in CD after failure of and/or intolerance to two different anti-TNF antibodies. METHODS Crohn's disease patients who received ADA or CZP after loss of response and/or intolerance to two anti-TNF agent were included in this retrospective study. Data were collected using a standardized questionnaire. Clinical response, duration, safety and reasons for discontinuation were assessed. RESULTS Sixty-seven patients treated with CZP (n = 40) or ADA (n = 27) were included. A clinical response was observed in 41 (61%) at week 6 and 34 patients (51%) at week 20. The probability of remaining under treatment at 3 months, 6 months and 9 months was 68%, 60% and 45%, respectively. At the end of follow-up, the third anti-TNF had been stopped in 36 patients for intolerance (n = 13), or failure (n = 23). Two deaths were observed. CONCLUSIONS The treatment with a third anti-TNF (CZP or ADA) agent of CD patients, who have experienced loss of response and/or intolerance to two anti-TNF antibodies, has favourable short-term and long-term efficacy. It is an option to be considered in patients with no other therapeutic options.

Abstract
The present paper summarizes the consensus views of a group of 9 European clinicians and scientists on the current state of scientific knowledge on probiotics, covering those areas where there is substantial evidence for beneficial effects and those where the evidence base is poor or inconsistent. There was general agreement that probiotic effects were species and often strain specific. The experts agreed that some probiotics were effective in reducing the incidence and duration of rotavirus diarrhoea in infants, antibiotic-associated diarrhoea in adults and, for certain probiotics, Clostridium difficile infections. Some probiotics are associated with symptomatic improvements in irritable bowel syndrome and alleviation of digestive discomfort. Probiotics can reduce the frequency and severity of necrotizing enterocolitis in premature infants and have been shown to regulate intestinal immunity. Several other clinical effects of probiotics, including their role in inflammatory bowel disease, atopic dermatitis, respiratory or genito-urinary infections or H.pylori adjuvant treatment were thought promising but inconsistent.

Abstract
The management of Crohn's disease is rapidly changing. The advent of potent immunomodulatory and biologic therapies has led to more demanding endpoints for clinical trials than only clinical response and remission. Complete withdrawal of corticosteroids, healing of endoscopically visible lesions, and prevention of structural damage are only a few new endpoints that are finding their way into the clinical trials of today and those that are being developed for the future. Given the importance of selecting the most appropriate and relevant endpoints, the International Organization for Inflammatory Bowel Diseases (IOIBD) decided to develop guidelines that could be used by individual researchers, the pharmaceutical industry, and the regulatory bodies. The current document is to be read as a "position paper," which is the result of several years of discussion and consensus finding that was finally approved by the entire membership of the group. The proposed instruments will need further validation and standardization to demonstrate that they are reliable in stable disease and responsive to change, and to determine the cutoff points for response and remission.

Abstract
Stenosis is the most frequent complication during Crohn's disease. The lesion can be inflammatory, or due to a fibrosing or neoplastic process. The medical treatment with anti-inflammatory drugs is usually sufficient as first line treatment; fibrous lesions require endoscopic or surgical procedures while neoplastic lesions require surgery. A multidisciplinary approach (radiologic, medical, surgical and endoscopic) is needed. In a first part, we discuss the definition of stenosis and the modalities of imaging (particularly MRI) and of treatment (particularly with TNFalpha antagonists). Then we expose the strategy for the management of the most frequent clinical situations: occlusion, ileal inflammatory stenosis, stenosis of an ileocolonic anastomosis and chronic fibrous stenosis. The treatment decision takes into account the results of radiological assessment, CRP level and the effects of the previous treatments.

Abstract
BACKGROUND AND AIMS A previous study suggested that the presence of myenteric plexitis in the proximal resection margins could be predictive of early endoscopic recurrence after ileocolonic or ileal resection for Crohn's disease (CD). The aim of the present study was to assess the predictive value of plexitis for early clinical CD recurrence. METHODS All consecutive patients with ileocolonic or ileal resection for active CD in Lariboisière Hospital (Paris) between 1995 and 2006 were included. Clinical, surgical, histological and follow-up data were extracted from medical charts. Early clinical recurrence was defined as the reappearance of CD clinical manifestations requiring a specific treatment within 2 years postsurgery. The proximal resection margin was analysed using haematein eosin saffron (HES) staining and immunochemistry targeting mastocytes (anti-CD117 antibody) and lymphocytes (anti-CD3 antibody). Eosinophils were detected by HES staining. Ten cases of ileocolonic resections for caecal carcinoma served as controls. RESULTS Data were available from 171 postoperative follow-up periods in 164 patients with CD. Early clinical recurrence of CD occurred in 28.1%. In multivariate analysis, factors associated with postoperative recurrence were active smoking (hazard ratio (HR) = 1.94; 95% CI 1.06 to 3.60; p = 0.033), submucosal plexitis with >or=3 mastocytes (HR = 1.87; 95% CI 1.00 to 3.46; p = 0.048) and a disease-free resection margin <5 cm (HR = 0.52; 95% CI 0.27 to 1.02; p = 0.059). CONCLUSIONS Submucosal plexitis is associated with early clinical recurrence and could be taken into account in studies searching for new treatment strategies in the immediate postoperative period.

Abstract
INTRODUCTION A previous randomised controlled trial has demonstrated that oral plus topical mesalazine enema is more effective than oral mesalazine alone for achieving clinical remission in mild-to-moderately active extensive ulcerative colitis (UC). To evaluate whether this strategy is cost-effective we conducted an economic evaluation comparing 1 g topical mesalazine in combination with 4 g oral mesalazine compared to 4 g mesalazine monotherapy in mild-to-moderately active UC. METHODS The economic evaluation was based on the ability to achieve remission using changes from baseline in the ulcerative colitis disease activity instrument (UCDAI). A cost-utility analysis was used where the main outcome was quality-adjusted life years to reflect improved quality of life associated with achieving remission compared with active disease. A simulated Markov model with five health states was constructed to model cost and outcome changes over time: (1) active UC; (2) mesalazine-refractory active UC; (3) steroid-refractory active UC; (4) infliximab-responsive active UC; and (5) remission. To reflect parameter uncertainty in the cost-effectiveness analysis probabilistic sensitivity analysis (PSA) was conducted by varying relevant clinical parameters. RESULTS Average treatment costs required to transition a patient from active UC to remission using oral and topical mesalazine compared with oral alone were £1812 and £2390, respectively. Improved remission rates attributed to oral and topical mesalazine resulted in moderate improvements in quality-adjusted life years (QALYs) compared to oral mesalazine alone. Disaggregation of medical costs indicated that medical consultations and diagnostic costs were similar for both treatment arms. An abbreviated analysis which considered costs up to steroid-refractory patients in subacute UC indicated that combination therapy offered a cost-savings of £285 over 16 weeks of therapy compared with monotherapy. CONCLUSIONS The results indicate that the addition of 1 g topical mesalazine results in significant cost-savings and moderate quality of life improvements. We have also shown that irrespective of which treatment modality is used in steroid-refractory patients (eg, infliximab, azathioprine, ciclosporine) that topical mesalazine is cost-saving.

Abstract
Natural orifice translumenal endoscopic surgery (NOTES) allows access into the peritoneal cavity with a flexible endoscope, through the wall of the digestive or urogenital tracts. NOTES can be combined to laparoscopic surgery in so-called << hybrid >> techniques. In the absence of any incision of the abdominal wall, NOTES procedures provide perfect cosmetic results, with virtually no risk of parietal complications, and with decreased postoperative pain. NOTES could particularly benefit to overweight patients and to patients receiving intensive or palliative care. Most NOTES studies have been performed on animal models, with great interest for both transgastric and transpelvic approaches. Successful NOTES peritoneoscopy, hysterectomy, oophorectomy, tubal ligation, gastrojejunal anastomosis, cholecystectomy, splenectomy, nephrectomy, and abdominal-wall hernia repair have been described. In human studies, the transvaginal route is preferred. NOTES clinical research focuses on low-morbidity procedures, such as cholecystectomy, appendectomy, and peritoneoscopy. Indirect benefits are expected from this research, with possible technological innovations in the field of endoscopic instrumentation (including sutures, anastomosis, traction and triangulation). Overall, NOTES is believed to make evolve both interventional endoscopy and minimally invasive surgery.

Abstract
BACKGROUND The intestinal microbiota is suspected to play a role in colitis and particularly in inflammatory bowel disease (IBD) pathogenesis. The aim was to compare the fecal microbiota composition of patients with colitis to that of healthy subjects (HS). METHODS fecal samples from 22 active Crohn's disease (A-CD) patients, 10 CD patients in remission (R-CD), 13 active ulcerative colitis (A-UC) patients, 4 UC patients in remission (R-UC), 8 infectious colitis (IC) patients, and 27 HS were analyzed by quantitative real-time polymerase chain reaction (PCR) targeting the 16S rRNA gene. Bacterial counts were transformed to logarithms (Log(10) CFU) for statistical analysis. RESULTS Bacteria of the phylum Firmicutes (Clostridium leptum and Clostridium coccoides groups) were less represented in A-IBD patients (9.7; P = 0.004) and IC (9.4; P = 0.02), compared to HS (10.8). Faecalibacterium prausnitzii species (a major representative of the C. leptum group) had lower counts in A-IBD and IC patients compared to HS (8.8 and 8.3 versus 10.4; P = 0.0004 and P = 0.003). The Firmicutes/Bacteroidetes ratio was lower in A-IBD (1.3; P = 0.0001) and IC patients (0.4; P = 0.002). Compared to HS, Bifidobacteria were less represented in A-IBD and IC (7.9 and 7.7 versus 9.2; P = 0.001 and P = 0.01). CONCLUSIONS The fecal microbiota of patients with IBD differs from that of HS. The phylum Firmicutes and particularly the species F. prausnitzii, are underrepresented in A-IBD patients as well as in IC patients. These bacteria could be crucial to gut homeostasis since lower counts of F. prausnitzii are consistently associated with a reduced protection of the gut mucosa.

Abstract
BACKGROUND Cyclosporine is considered a safe and effective treatment of severe steroid-refractory ulcerative colitis (UC). However, few data are available concerning its safety profile in pregnant women. We report here the experience of 5 GETAID centers. METHODS In a retrospective study data on patients with severe UC treated with cyclosporine during pregnancy were extracted from medical records of consecutive patients treated between 2001 and 2007. RESULTS Eight patients (median age 30.5 years old) were identified. At the time of flare-up the median duration of pregnancy was 11.5 weeks of gestation (range 4-25). Seven patients had pancolitis. All patients had more than 3 commonly used clinical and biological severity criteria. Three patients had severe endoscopic lesions and 5 patients had not. All patients received intravenous corticosteroids for at least 7 days before introduction of cyclosporine. Two patients received azathioprine during treatment with cyclosporine. No severe infections or other complications due to treatment were observed. Treatment was effective in 7/8 patients. One patient received infliximab due to cyclosporine therapy failure with a good outcome. No colectomy was performed during pregnancy. Seven pregnancies were conducted to term, but 1 in utero death occurred due to maternal absence of S-protein. Two newborns were premature, including 1 case of hypotrophy. No malformations were observed. CONCLUSIONS In our experience, treatment with cyclosporine for steroid-refractory UC during pregnancy can be considered safe and effective.

Abstract
Close, tightly orchestrated interactions between the intestinal epithelium and the mucosa-associated immune system are critical for normal intestinal absorptive and immunological functions. Recent data indicate that commensal intestinal microbiota represents a major modulator of intestinal homeostasis. This review analyzes the process of intestinal colonization and the interaction of microbiota with the intestinal epithelium and mucosal immune system, with special reference to the first years of extrauterine life. Dysregulation of the symbiotic interaction between intestinal microbiota and the mucosa may result in a pathological condition with potential clinical repercussions. Based on the concept that there is a beneficial and symbiotic relation between the host and endogenous microbiota, strategies aimed at directly modulating intestinal microbiota with regard to disease prevention or treatment have been developed. One strategy involves administering viable probiotic bacteria. Clinical evidence for the beneficial effect of probiotics in the prevention and/or treatment of necrotizing enterocolitis, infectious and antibiotic-associated diarrhea, allergic diseases, and inflammatory bowel disorders is reviewed herein.

Abstract
Lactobacillus casei DN-114 001 is a probiotic strain able to interact with the immune system and to interfere with gastrointestinal pathogens. The derived strain DN-114 001Rif was studied during its transit through the upper and distal intestine of human volunteers. Seven volunteers participated in the study, which involved intestinal intubation to sample ileal contents and collection of fecal samples, with a wash-out period of 8 days between the 2 steps. The retrieval of the probiotic was analyzed in the ileum every 2 h for 8 h following the ingestion of one dose of the test product and in the feces prior to, during, and after daily consumption of the test product for 8 days. Persistence of the probiotic amplifiable DNA was assessed using temporal temperature gradient gel electrophoresis and real-time PCR. Fluorescent in situ hybridization allowed analysis of the composition of the dominant digestive microbiota. The ingestion of L. casei DN-114 001Rif led to a significant and transient increase of its amplifiable DNA in ileal and fecal samples. This is related to a high stability in the composition of dominant groups of the gut microbiota. Data from ileal samples are scarce and our study confirms the potentiality for interaction between probiotics and the human immune system.
