Abstract
The timely introduction and adjustment of the appropriate drug in accordance with previously well-defined treatment goals is the foundation of the approach in the treatment of inflammatory bowel disease (IBD). The therapeutic approach is still evolving in terms of the mechanism of action but also in terms of the possibility of maintaining remission. In patients with achieved long-term remission, the question of de-escalation or discontinuation of therapy arises, considering the possible side effects and economic burden of long-term therapy. For each of the drugs used in IBD (5-aminosalycaltes, immunomodulators, biological drugs, small molecules) there is a risk of relapse. Furthermore, studies show that more than 50% of patients who discontinue therapy will relapse. Based on the findings of large studies and meta-analysis, relapse of disease can be expected in about half of the patients after therapy withdrawal, in case of monotherapy with aminosalicylates, immunomodulators or biological therapy. However, longer relapse-free periods are recorded with withdrawal of medication in patients who had previously been on combination therapies immunomodulators and anti-tumor necrosis factor. It needs to be stressed that randomised clinical trials regarding withdrawal from medications are still lacking. Before making a decision on discontinuation of therapy, it is important to distinguish potential candidates and predictive factors for the possibility of disease relapse. Fecal calprotectin level has currently been identified as the strongest predictive factor for relapse. Several other predictive factors have also been identified, such as: High Crohn's disease activity index or Harvey Bradshaw index, younger age (< 40 years), longer disease duration (> 40 years), smoking, young age of disease onset, steroid use 6-12 months before cessation. An important factor in the decision to withdraw medication is the success of re-treatment with the same or other drugs. The decision to discontinue therapy must be based on individual approach, taking into account the severity, extension, and duration of the disease, the possibility of side adverse effects, the risk of relapse, and patient's preferences.

Abstract
BACKGROUND Ulcerative proctitis (UP) is a common highly symptomatic form of ulcerative colitis that can be difficult to treat. AIM To assess the efficacy of medical treatments for UP. METHODS We searched MEDLINE, EMBASE, and CENTRAL on 23 November 2022 for randomised controlled trials (RCTs) of medical therapy for adults with UP. Primary outcomes included induction and maintenance of clinical remission. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated for each outcome. RESULTS We included 53 RCTs (n = 4096) including 46 induction studies (n = 3731) and seven maintenance studies (n = 365). First-line therapies included topical 5-aminosalicylic acid (5-ASA), conventional corticosteroids, budesonide, and oral 5-ASA. Therapy for refractory UP included topical tacrolimus and small molecules. Topical 5-ASA was superior to placebo for induction (RR 2.72, 95% CI 1.94-3.82) and maintenance of remission (RR 2.09, 95% CI 1.26-3.46). Topical corticosteroids were superior to placebo for induction of remission (RR 2.83, 95% CI 1.62-4.92). Topical budesonide was superior to placebo for induction of remission (RR 2.34, 95% CI 1.44-3.81). Combination therapy with topical 5-ASA and topical corticosteroids was superior to topical monotherapy with either agent. Topical tacrolimus was superior to placebo. Etrasimod was superior to placebo for induction (RR 4.71, 95% CI 1.2-18.49) and maintenance of remission (RR 2.08, 95% CI 1.31-3.32). CONCLUSIONS Topical 5-ASA and corticosteroids are effective for active UP. Topical 5-ASA may be effective for maintenance of remission. Tacrolimus may be effective for induction of remission. Etrasimod may be effective for induction and for maintenance of remission. Trials should include UP to expand the evidence base for this under-represented population.

Placebo Rates in Randomized Controlled Trials of Proctitis Therapy: A Systematic Review and Meta-Analysis Placebo Response in Proctitis. J Crohns Colitis 2023; 17:123-136. [PMID: 35930405 DOI: 10.1093/ecco-jcc/jjac109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND AND AIMS Treatment options for proctitis are limited. To assist trial design for novel therapeutics, we conducted a systematic review and meta-analysis of proctitis randomized controlled trials [RCTs] to quantify placebo rates and identify factors influencing them. METHODS We searched MEDLINE, EMBASE and CENTRAL from inception to June 2021. Placebo-controlled trials of pharmacological interventions for proctitis were eligible. Placebo clinical response and remission rates for induction and maintenance trials were extracted and pooled using a random-effects model. Mixed-effects meta-regression was used to evaluate the impact of patient and study-level characteristics. RESULTS Twenty RCTs [17 induction and four maintenance phases] were included. The most common intervention was aminosalicylates and most studies investigated topical medications. The pooled placebo clinical response and remission rates for induction trials were 28% (95% confidence interval [CI] 22-35%; n = 17) and 20% [95% CI 12-32%; n = 9], respectively. Pooled placebo endoscopic response and remission rates were 32% [95% CI 26-39%, n = 12] and 18% [95% CI 9-33%, n = 6], respectively. For maintenance trials, the pooled placebo clinical remission rate was 29% [95% CI 16-46%, n = 17]. Trials published after 2005 and trials with a longer duration of follow-up were associated with significantly lower placebo response rates. Nineteen of 20 studies were assessed as having an unclear risk of bias, reflecting the historical nature of trials. CONCLUSIONS Placebo response and remission rates in proctitis trials are influenced by trial phase and the endpoint being assessed. These contemporary rates will inform trial design for novel therapeutics for treatment of proctitis, which is a large unmet need.

Abstract
BACKGROUND Ulcerative proctitis is a common and often highly symptomatic form of inflammatory bowel disease. We performed a systematic review to assess the efficacy of different therapies in the management of patients with ulcerative proctitis. METHODS We identified randomized controlled trials in adults with ulcerative proctitis treated with oral or topical therapies for induction of response or remission, or prevention of relapse. RESULTS A total of 32 randomized controlled trials were included [27 induction/2839 participants, five maintenance/334 participants]. Follow-up varied from 3 to 8 weeks for induction, and from 6 to 24 months for maintenance of remission. 5-Aminosalicylic acid [5-ASA] suppository was the most frequently evaluated treatment [14/32, 43.7%], followed by steroid enema [7/32, 21.9%]. Topical 5-ASA demonstrated effectiveness for induction of clinical response or remission and prevention of relapse in several studies. Combined topical steroids and 5-ASA was more effective than topical 5-ASA or topical steroids alone to induce response [100% of patients for combination vs 70% for beclomethasone alone and 76% for 5-ASA alone]. One observational study suggested azathioprine may be effective in patients with ulcerative proctitis. Only two cohort studies evaluated the efficacy of tumour necrosis factor inhibitors in ulcerative proctitis. Small molecules, anti-integrins and anti-interleukin therapies have not been evaluated in isolated ulcerative proctitis. CONCLUSION The role of topical 5-ASA as a treatment for ulcerative proctitis has been confirmed in this systematic literature review, for induction and maintenance of remission. Future trials are needed to investigate the efficacy of more recent and upcoming drug classes in patients with ulcerative proctitis.

Abstract
INTRODUCTION Since the first edition of the Guidelines was published in 2013, much information has been generated around the treatment of ulcerative colitis, and new drugs and action protocols have been introduced. Clinical practice has changed substantially, warranting new approaches and a comprehensive review and update of the evidence. MATERIAL AND METHODS Once again, we used the GRADE approach, supported by an electronic tool (https://gradepro.org). The clinical scenarios are the same as in the previous version (induction and maintenance in severe and mild-moderate flare-ups), as are the variables and their evaluation. However, in the updated guidelines, three questions have been deleted, 14 added and 30 maintained, making a total of 44 clinical questions. After an exhaustive review of the evidence, the recommendations are now updated. RESULTS Of the 44 questions analysed, no recommendation could be established in two due to the very low quality of the evidence, while in the other 42, based on different degrees of quality of evidence, recommendations were made according to the GRADE system. In 25 of these questions the final recommendation is strongly in favour, in six strongly against, in seven weakly in favour and in four weakly against. According to the scenarios and recommendations, six algorithms are proposed as a simple guide for practical decision-making. CONCLUSIONS The aim of this update of the 2013 guidelines is to provide answers, based on the GRADE approach, to the different questions we ask ourselves daily when deciding the most appropriate treatment for our patients with ulcerative colitis in the different clinical scenarios.

Abstract
BACKGROUND 5-Aminosalicylates [5-ASAs] are the mainstay of treatment for ulcerative colitis [UC]. The optimum preparation, dose, and route of administration for UC remain unclear. We conducted a network meta-analysis to examine this issue. METHODS We searched MEDLINE, EMBASE, EMBASE Classic, and the Cochrane central register of controlled trials from inception to December 2020. We included randomised controlled trials [RCTs] comparing oral, topical, or combined oral and topical 5-ASAs, with each other or placebo for induction of remission or prevention of relapse of UC. Results were reported as pooled relative risks [RRs] with 95% confidence intervals [CIs] to summarise effect of each comparison tested, with treatments ranked according to P-score. RESULTS We identified 40 RCTs for induction of remission and 23 for prevention of relapse. Topical mesalazine [P-score 0.99], or oral and topical mesalazine combined [P-score 0.87] ranked first and second for clinical and endoscopic remission combined. Combined therapy ranked first in trials where ≥50% of patients had left-sided/extensive disease, and topical mesalazine first in trials where ≥50% of patients had proctitis/proctosigmoiditis. High-dose [≥3.3 g/day] oral mesalazine ranked third in most analyses, with the most trials and most patients. For relapse of disease activity, combined therapy and high-dose oral mesalazine ranked first and second, with topical mesalazine third. 5-ASAs were safe and well tolerated, regardless of regimen. CONCLUSIONS Our results support previous evidence; however, higher doses of oral mesalazine had more evidence for induction of remission than combined therapy and were significantly more efficacious than lower doses. Future RCTs should better establish the role of combined therapy for induction of remission, as well as optimal doses of oral 5-ASAs to prevent relapse.

Abstract
BACKGROUND 5-aminosalicylates (5-ASA) are widely used in inflammatory bowel disease (IBD), but emerging evidence suggests that they may be safely withdrawn in significant subsets of patients. This is important to address: 5-ASA therapy accounts for up to 25% of total healthcare costs in ulcerative colitis (UC), while almost a third of patients with Crohn's disease (CD) receive long-term 5-ASA despite no clear evidence of benefit. Further, rationalising medication burden may improve overall adherence and outcome. AIMS To summarise the rationale for 5-ASA withdrawal, review the current evidence in both UC and CD and consider the data surrounding colorectal cancer (CRC) prevention, guiding an evidence-based withdrawal strategy. METHODS PubMed was searched to identify relevant studies. Only papers published in English were reviewed, with priority given to randomised clinical trials and meta-analyses. RESULTS For patients with UC, consideration of 5-ASA withdrawal should be made on a case-by-case basis, but it appears safest for those in deep remission without any of the following risk factors: younger age (<40 years), remission for less than 2 years, a history of multiple flares, extensive disease. 5-ASA withdrawal should also be considered in patients with UC escalated to biologic therapy who have achieved remission and in all patients with CD. Although 5-ASA therapy may have chemopreventive benefits for CRC, the cost-benefit ratio appears significant, and this indication is not justified by evidence in those who have achieved remission and are continuing therapy with other agents, or in those in sustained remission without a history of extensive disease. CONCLUSIONS Although the majority of patients with IBD receive 5-ASA during their disease course, safe withdrawal appears possible in many, with important implications for both health economics and patient experience. A number of unanswered questions, however, remain.

Abstract
BACKGROUND It is important to minimize placebo rates in randomised controlled trials (RCTs) to efficiently detect treatment differences between interventions. Historically, high placebo rates have been observed in clinical trials of ulcerative colitis (UC). A better understanding of factors influencing placebo rates may lead to more informed clinical trial design. OBJECTIVES A systematic review and meta-analysis was conducted to evaluate placebo response and remission rates in RCTs evaluating UC treatments in adult patients. SEARCH METHODS Electronic databases (i.e. MEDLINE, EMBASE, and CENTRAL) were searched from inception to 1 March 2017 with no language restrictions applied. Reference lists and conference proceedings of major gastroenterology meetings were also handsearched to identify additional studies. SELECTION CRITERIA Placebo-controlled RCTs of adult patients with UC treated with corticosteroids, aminosalicylates, immunosuppressives or biologics were eligible, provided enrolment and outcome assessment was conducted using the Ulcerative Colitis Disease Activity Index (UCDAI) or the Mayo Clinic Score. The minimum trial duration was two weeks for induction trials and four months maintenance trials. DATA COLLECTION AND ANALYSIS Pairs of authors independently determined study eligibility and extracted data with any disagreements resolved through consensus. Outcomes of interest included the proportion of patients with clinical response and remission. Trial characteristics such as the design, participant demographics and disease history, interventions, and enrolment and assessment criteria were also recorded. The methodological quality of the included studies was evaluated using the Cochrane risk of bias tool. Pooled placebo response and remission rates and 95% confidence intervals (95% CI) were calculated using a binomial normal model for proportions. Induction of remission and maintenance studies were pooled separately. The impact of study-level characteristics on placebo response and remission rates was investigated using mixed-effects meta-regression analyses with logits of event rates as the outcome variables. An assessment of pooled placebo rates over time was conducted using a cumulative meta-analysis based on date of publication. Publication bias was examined using funnel plots. MAIN RESULTS The screening process identified 61 included studies which encompass 58 induction phases (5111 patients randomised to placebo) and 12 maintenance phases (1579 patients randomised to placebo). For induction trials, the pooled estimate of placebo response was 33% (95% CI 30% to 36%) while the pooled estimate of placebo remission was 12% (95% CI 9% to 15%). For maintenance trials, the pooled estimate of placebo response was 23% (95% CI 19% to 28%) while the pooled estimate of placebo remission was 17% (95% CI 10% to 27%).Studies enrolling patients with more active disease confirmed objectively by endoscopy were associated with significantly lower placebo remission and response rates than trials enrolling patients with less active disease (27% versus 4%, OR 2.60, 95% CI 1.25 to 5.42, P = 0.01 for UCDAI endoscopy sub score ≥1 versus ≥ 2 for remission; and 27% versus 4%, OR 1.70, 95% CI 1.02 to 2.82, P = 0.02 for UCDAI endoscopy sub score greater than or equal to one versus greater than or equal to two for response). With respect to drug class, the lowest placebo response and remission rates were observed in trials evaluating corticosteroids (23%; 95% CI 19 to 29%, and 5%; 95% CI 2 to 11%, respectively). Trials of biologics had the highest placebo response rate (35%; 95% CI 30 to 41%), while trials evaluating aminosalicylates had the highest placebo remission rate (18%; 95% CI 12 to 24%). Disease duration of greater than five years prior to enrolment was associated with a significantly lower placebo response rate compared to disease duration of less than or equal to five years (29% versus 47%, respectively; OR 0.54, 95% CI 0.32 to 0.92, P = 0.02). The requirement of a minimum rectal bleeding score for study eligibility was associated with an increased placebo response rate compared to studies that did not use rectal bleeding for trial eligibility (37% versus 32%, respectively; OR 1.70, 95% CI 1.02 to 2.82, P = 0.02). Finally, the time point of primary outcome assessment was found to be significantly associated with placebo remission rates such that every one week increment in endpoint assessment was associated with a 6% increase in the placebo remission rate (OR 1.06, 95% CI 1.02 to 1.10, P = 0.01).Cumulative meta-analysis indicated a consistent increase in the placebo response rate from 1987 to 2007 (from 13% to 33%), although rates have remained constant from 2008 to 2015 (32% to 34%). Similarly, placebo remission rates increased from 1987 to 2007 (5% to 14%) but have remained constant from 2008 to 2015 (12 to 14%). On meta-regression, there were no statistically significant differences between the 1987-2007 and 2008-2015 point estimates for both response (P = 0.81) and remission (P = 0.32). AUTHORS' CONCLUSIONS Placebo response and remission rates vary according to endoscopic disease severity and rectal bleeding score at trial entry, class of agent, disease duration, and the time point at which the primary outcome was measured. These observations have important implications for the design and conduct of future clinical trials in UC and will help researchers design trials, determine required sample sizes and also provide useful information about trial design features which should be considered when planning new trials.

Abstract
BACKGROUND Disease activity can be determined using clinical, endoscopic or histologic criteria in patients with ulcerative colitis (UC). Persistent disease activity is associated with poor outcomes. Histologic disease activity has been shown to be associated with relapse, colectomy and colorectal cancer. The ability to objectively evaluate microscopic disease activity using histology is important for both clinical practice and clinical trials. However, the operating properties of the currently available histologic indices remain unclear. OBJECTIVES A systematic review was undertaken to identify and evaluate the development and operating characteristics of histologic disease activity indices used to assess disease activity in people with ulcerative colitis. SEARCH METHODS We searched MEDLINE, EMBASE, PubMed, CENTRAL and the Cochrane IBD Review Group Specialized Trials Register from inception to 2 December 2016 for applicable studies. There were no language or document type restrictions. SELECTION CRITERIA Any study design (e.g. randomized controlled trials, cohort studies, case series) that evaluated a histologic index in patients with UC were considered for inclusion. Eligible patients were adults (> 18 years), diagnosed with UC using conventional clinical, radiographic, endoscopic and histologic criteria. DATA COLLECTION AND ANALYSIS Two authors (MHM and CEP) independently reviewed the titles and abstracts of the studies identified from the literature search. A standardized form was used to assess eligibility of trials for inclusion and for data extraction.Two authors (MHM and CEP) independently extracted and recorded data, which included the number of patients enrolled, number of patients per treatment arm, patient characteristics including age and gender distribution, and the name of the histologic index. Outcomes (i.e. intra-rater reliability, inter-rater reliability, internal consistency, content validity, criterion validity, construct validity, responsiveness, and feasibility) were recorded for each trial. MAIN RESULTS In total, 126 reports describing 30 scoring indices were identified through the screening process. Eleven of the 30 scoring indices have undergone some form of index validation. Intra-rater reliability was assessed for eight scoring indices. Inter-rater reliability was evaluated for all 11 of the scoring indices. Three of the indices underwent content validation. Two of the included scoring indices assessed criterion validity. Six of the included scoring indices explored content validity. Two of the included scoring indices were tested for responsiveness. AUTHORS' CONCLUSIONS The Nancy Index and the Robarts Histopathology Index have undergone the most validation in that four operating properties including reliability, content validity, construct validity (hypothesis testing) and criterion validity have been tested. However, none of the currently available histologic scoring indices have been fully validated. In order to determine the optimal endpoint for histologic healing in UC, more research is required. The optimal index would need to be fully validated.

Abstract
BACKGROUND No studies have monitored the levels of faecal calprotectin (FC) during mesalazine suppository therapy for proctitis in ulcerative colitis (UC). AIMS To evaluate the value of consecutive monitoring of FC in patients with UC during mesalazine suppository therapy. METHODS One hundred and sixty patients with active inflammation limited to the rectum were treated with mesalazine 1 g suppository once daily for 8 weeks. Patients who achieved clinical remission were advised to maintain the treatment, and were followed up for further 40 weeks. FC levels were measured every 8 weeks during the study. RESULTS At week 8, 118 patients (74%) went into clinical remission, of whom 88 achieved endoscopic healing. The median FC level significantly decreased in patients with clinical and endoscopic remission (both P < 0.0001), while it did not change significantly in those without remission. Eighty (68%) of the 118 patients with remission continued the treatment. Twenty-four patients (30%) relapsed during the 40-week follow-up. In patients with clinical relapse, the median FC level elevated already 8 weeks before the diagnosis of relapse. In contrast, in patients who maintained remission it remained at a low level and did not significantly change during the follow-up. Elevated FC level (≥55 μg/g) was useful for the early diagnosis of relapse (88% sensitivity and 80% specificity). CONCLUSIONS Faecal calprotectin may represent a useful biomarker for the assessment of disease activity in UC patients treated with mesalazine suppositories. Serial monitoring of faecal calprotectin appears to be valuable for the prediction and early diagnosis of relapse during maintenance therapy.

Abstract
In recent decades, the incidence of ulcerative colitis (UC) presents a gradually upward trend. The combination of topical and oral therapy is more widely adopted in current management of UC in comparison with traditional oral therapy. As a typical topical therapy, suppository treatment has received increasing attention due to its convenience, high tolerance and good curative effect. Aminosalicylic acid preparations are the major Western medicine suppositories, consisting of sulfasalazine suppository and mesalazine suppository, with the latter considered the first choice for mild-to-moderate UC due to better efficacy and fewer side effects. For traditional Chinese medicine (TCM), several drugs have been applied as suppositories. Qingchang suppository is a representative of TCM suppositories whose therapeutic principle is based on heat-clearing and detoxicating effects. This article reviews the recent progress in suppository treatment of UC.

Abstract
BACKGROUND Patients with ulcerative colitis limited to the proctum are considered to have ulcerative proctitis (UP). In patients with more extensive ulcerative colitis, treatment occurs in a step-up fashion (5-ASA, corticosteroids, thiopurines, anti-TNF-α agents), a strategy which has proven effective. Although treatment of UP occurs using the same step-up design, the efficacy of these therapies in UP is scarcely studied. The objectives were to systematically review the literature for randomized controlled trials studying drug therapies for induction and maintenance of remission in patients with UP. METHODS Electronic databases and reference lists of review articles were searched. The primary outcomes were clinical remission induction rate and the maintained clinical remission rate. Secondary outcomes were induction and maintenance of endoscopic and histological remission. Relative risks (RR) and 95% confidence intervals (CI) for were calculated. RESULTS Twenty-three studies (1834 patients) were included. Eighteen trials investigated induction and 5 studied maintenance of remission. Topical 5-ASA was significantly superior to placebo for induction (RR, 2.39; 95% CI, 1.63-3.51) and maintenance (RR, 2.80; 95% CI, 1.21-6.45) of clinical remission, regardless of dose or formulation. Subgroup analysis of 5-ASA suppositories also showed superiority over placebo for induction of clinical (RR, 3.07; 95% CI, 1.70-5.55) and endoscopic remission (RR, 2.64; 95% CI, 1.85-3.77). CONCLUSIONS Topical 5-ASA is superior to placebo for the induction and maintenance of clinical remission and for the induction of endoscopic remission. The efficacy of corticosteroids, thiopurines, and anti-TNFα has been insufficiently studied in patients with UP.

Abstract
BACKGROUND Chronic active ulcerative colitis (UC) is associated with significant morbidity, loss of productivity, increased colorectal cancer risk and cost. Up to 18% of patients suffer chronic active disease, with 30% requiring colectomy at 10 years. The management remains challenging given the relatively few clinical trials in this area. AIM To summarise the evidence regarding optimal management strategies for patients with chronic active UC of differing disease extents and degrees of treatment refractoriness. METHOD A literature search using the PubMed and Medline databases was performed. No time limit was set on article publication for inclusion. RESULTS The principles of management should focus on confirming disease activity, exclusion of alternative diagnoses, adherence and treatment escalation. Infliximab and topical tacrolimus are options in refractory proctitis, although the evidence for these therapies is limited. Both infliximab and adalimumab are effective in corticosteroid-refractory disease, although the proportions of patients achieving corticosteroid-free remission remain modest (24% at 30 weeks and 16.9% at 8 weeks respectively). Alternatives include ciclosporin and tacrolimus, and possibly methotrexate. Colectomy often leads to an improved quality of life; medical strategies unlikely to provide durable corticosteroid-free remission should not be pursued. CONCLUSIONS No current pharmacological treatment delivers mucosal healing in the majority of patients. Newer treatments such as vedolizumab and tofacitinib may represent valuable future therapies. Available medical options should be discussed with patients at every step of their management, with an honest appraisal of the evidence. Surgery should always be considered in patients with chronic refractory disease of any extent.

Abstract
BACKGROUND AND AIM Topical mesalamine or corticosteroid has shown efficacy in patients with ulcerative proctitis, but patients often become refractory to these interventions. Xilei San is a herbal preparation with evidence of anti-inflammatory effects. We evaluated the efficacy of topical Xilei San in ulcerative proctitis patients. METHODS In a double blind setting, 30 patients with intractable ulcerative proctitis despite ≥ 4 weeks of topical mesalamine or corticosteroid were randomly assigned to True (n = 15) and placebo (n = 15). Patients in True received suppository Xilei San (0.1 g/dose per day of Xilei San), the other 15 received placebo suppository. The initial efficacy was evaluated on day 14. Primary endpoint of the trial was avoiding relapse during 180 days, relapse meant recurrence of active disease. Riley's index was applied for endoscopic and histological evaluations, while patients' quality of life was evaluated by an inflammatory bowel disease questionnaire. RESULTS On day 14, the number of patients who achieved remission, clinical activity index ≤ 4 in True was significantly higher versus placebo (P < 0.04). Likewise, at day 180, an 81.8% of patients in True were without relapse versus 16.7% in placebo (P < 0.001). Further, significant endoscopic (P < 0.01), histological (P < 0.02) and inflammatory bowel disease questionnaire (P < 0.04) improvements were observed in True, but not in placebo. CONCLUSIONS This is the first controlled investigation showing significant clinical and endoscopic efficacy for Xilei San in patients with intractable ulcerative proctitis. Topical Xilei San was well tolerated, and was without safety concerns.

Abstract
BACKGROUND 5-Aminosalicylic acid (5-ASA) is a first-line therapy for inducing and maintaining remission of mild and moderately active ulcerative colitis (UC). When the proximal margin of inflammation is distal to the splenic flexure, 5-ASA therapy can be delivered as a rectal suppository, foam or liquid enema. OBJECTIVES The primary objective was to assess the efficacy and safety of rectal 5-ASA for maintaining remission of distal UC. SEARCH METHODS We searched MEDLINE (1966 to August 2012), the Cochrane Library (August 2012), abstracts from major gastroenterology meetings (1997-2011) and bibliographies of relevant publications to identify relevant studies. SELECTION CRITERIA Eligible studies were randomized controlled trials comparing rectal 5-ASA to placebo or another active treatment for a minimum duration of six months. Symptom scores needed to be assessed in at least one study outcome. Patients had to be at least 12 years of age with disease extent less than 60 cm from the anal verge or distal to the splenic flexure, as determined by barium enema, colonoscopy or sigmoidoscopy. Patients were expected to be in remission prior to the treatment trial. DATA COLLECTION AND ANALYSIS Study eligibility was independently assessed by three authors. Data were extracted using standardized forms by two independent reviewers, with inter-rater agreement assessed using Cohen's Kappa and disagreements resolved by consensus. In cases where clarification of study results or methodology was needed, corresponding authors were contacted. The methodological quality of each trial was assessed by the Cochrane risk of bias tool and by a 30-point scale developed and used previously by the authors. Pooled risk ratios (RR) and corresponding 95% confidence intervals (CI) for continued clinical, endoscopic and histologic remission were estimated for comparisons between rectal 5-ASA and placebo or oral 5-ASA, and for comparisons among 5-ASA doses. Heterogeneity was assessed using the Chi(2) test and visual inspection of forest plots. If no significant heterogeneity was identified (P > 0.10 for Chi(2)) a fixed-effect model (Mantel-Haenstzel) was used. If heterogeneity was significant, a random-effects model was used. MAIN RESULTS Nine studies (484 patients) met the pre-specified inclusion criteria (Kappa 1.00). Six studies were rated as low risk of bias. Three studies were rated as high risk of bias due to blinding (two open label and one single-blind). The total daily dose of rectal 5-ASA ranged from 0.5 g to 4 g, and dose frequency ranged from once to three times daily. 5-ASA was delivered as liquid enema in five studies or as a suppository in four studies. Follow-up ranged from 6 to 24 months. Rectal 5-ASA was significantly superior to placebo for maintenance of symptomatic remission over a period of 12 months.Sixty-two per cent of patients in the rectal 5-ASA group maintained symptomatic remission compared to 30% of patients in the placebo group (4 studies; 301 patients; RR 2.22, 95% CI 1.26 to 3.90; I(2) = 67%; P < 0.01). A GRADE analysis indicated that the overall quality of the evidence for the primary outcome was low due to imprecision (i.e. sparse data 144 events) and inconsistency (i.e. unexplained heterogeneity). Rectal 5-ASA was significantly superior to placebo for maintenance of endoscopic remission over a 12 month period. Seventy-five per cent of patients in the rectal 5-ASA group maintained endoscopic remission compared to 15% of patients in the placebo group (1 study; 25 patients; RR 4.88, 95% CI 1.31 to 18.18; P < 0.05). There was no statistically significant difference in the proportion of patients who experienced at least one adverse event. Sixteen per cent of patients in the rectal 5-ASA group experienced at least one adverse compared to 12% of placebo patients (2 studies; 160 patients; RR 1.35, 95% CI 0.63 to 2.89; I(2) = 0%; P = 0.44). The most commonly reported adverse events were anal irritation and abdominal pain. No statistically significant differences between rectal and oral 5-ASA were identified for either symptomatic or endoscopic remission over a period of six months. Eighty per cent of patients in the rectal 5-ASA group maintained symptomatic remission compared to 65% of patients in the oral 5-ASA group (2 studies; 69 patients; RR 1.24, 95% CI 0.92 to 1.66; I(2) = 0%; P = 0.15). A GRADE analysis indicated that the overall quality of the evidence for the primary outcome was low due to imprecision (i.e. sparse data 50 events) and high risk of bias (i.e. both studies in the pooled analysis were open label). Eighty per cent of patients in the rectal 5-ASA group maintained endoscopic remission compared to 70% of patients in the oral 5-ASA group (2 studies; 91 patients; RR 1.14, 95% CI 0.90 to 1.45; I(2) = 0%; P = 0.26). In two small trials, one comparing 2 g/day 5-ASA enemas to 4 g/day 5-ASA enemas and the other comparing 0.5 g/day 5-ASA suppositories to 1 g/day 5-ASA suppositories no dose response relationship was observed. AUTHORS' CONCLUSIONS The limited data available suggest that rectal 5-ASA is effective and safe for maintenance of remission of mild to moderately active distal UC. Well designed randomized trials are needed to establish the optimal dosing regimen for rectal 5-ASA, to compare rectal 5-ASA with rectal corticosteroids and to identify subgroups of patients who are more or less responsive to specific rectal 5-ASA regimens. The combination of oral and rectal 5-ASA appears to be more effective than either oral or rectal monotherapy for induction of remission. The efficacy of combination therapy for maintenance of remission has not been assessed and could be evaluated in future trials.

Abstract
BACKGROUND AND AIMS Pediatric ulcerative colitis (UC) shares many features with adult-onset disease but there are some unique considerations; therefore, therapeutic approaches have to be adapted to these particular needs. We aimed to formulate guidelines for managing UC in children based on a systematic review (SR) of the literature and a robust consensus process. The present article is a product of a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN). METHODS A group of 27 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to ESPGHAN and ECCO members. A list of 23 predefined questions were addressed by working subgroups based on a SR of the literature. RESULTS A total of 40 formal recommendations and 68 practice points were endorsed with a consensus rate of at least 89% regarding initial evaluation, how to monitor disease activity, the role of endoscopic evaluation, medical and surgical therapy, timing and choice of each medication, the role of combined therapy, and when to stop medications. A management flowchart, based on the Pediatric Ulcerative Colitis Activity Index (PUCAI), is presented. CONCLUSIONS These guidelines provide clinically useful points to guide the management of UC in children. Taken together, the recommendations offer a standardized protocol that allows effective, timely management and monitoring of the disease course, while acknowledging that each patient is unique.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by a relapsing and remitting course. The quality of life can decreases significantly during exacerbations of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies are currently used for the management of UC. However, many challenging issues exist and sometimes these lead to differences in practice between clinicians. Therefore, Inflammatory Bowel Diseases (IBD) Study Group of Korean Association for the Study of Intestinal Diseases (KASID) set out the Korean guidelines for the management of UC. These guidelines are made by the adaptation using several foreign guidelines and encompass treatment of active colitis, maintenance of remission and indication for surgery in UC. The specific recommendations are presented with the quality of evidence. These are the first Korean treatment guidelines for UC and will be revised with new evidences on treatment of UC.

Abstract
BACKGROUND & AIMS Topical 5-aminosalicylates (5-ASAs) such as mesalamine are effective in inducing remission in patients with mild to moderately active ulcerative colitis (UC). However, there has been no meta-analysis of their efficacy in preventing relapse of quiescent UC. METHODS We searched MEDLINE, EMBASE, and the Cochrane central register of controlled trials through July 2011 for randomized controlled trials comparing the effects of topical 5-ASAs with placebo in adults with quiescent UC. Dichotomous data were pooled to obtain relative risk (RR) of relapse of disease activity. The number needed to treat (NNT) was calculated from the reciprocal of the risk difference. Adverse events data were summarized. RESULTS The search identified 3061 citations; we analyzed data from seven (555 patients). All trials used mesalamine, but only one included patients with extensive disease. The duration of therapy ranged from 6-24 months. The RR of relapse of disease activity in patients with quiescent UC who were given topical mesalamine, compared with placebo, was 0.60 (95% confidence interval, 0.49-0.73; NNT = 3); there was no significant heterogeneity between studies (I(2) = 21%, P = .27). No significant differences in rates of adverse events rates were detected (RR = 1.01; 95% confidence interval, 0.59-1.72). CONCLUSIONS On the basis of a meta-analysis of 7 randomized controlled trials, topical mesalamine is effective in preventing relapse of quiescent UC, with no greater number of adverse events than placebo. However, because most studies included only patients with left-sided disease or proctitis, the efficacy of topical mesalamine in preventing relapse in patients with more extensive quiescent UC is not known.

Abstract
BACKGROUND The use of topical therapy in the treatment of ulcerative colitis has declined in recent years despite evidence of good efficacy. AIMS To review US prescription trends for 5-aminosalicylic acid (5-ASA) since the US approval of Asacol extended-release oral mesalazine (mesalamine) in 1992; to estimate the optimal level of 5-ASA exposure in the distal colon; to determine factors influencing distal colonic exposures; and to compare the effectiveness of different 5-ASA formulations (oral, topical suspension, foam, suppositories) in clinical trials. METHODS Review of clinical trials, physiologic studies and prescription trends of various mesalazine formulations for treatment of distal ulcerative colitis. RESULTS Between 1992 and 2009, prescriptions for oral mesalazine increased sixfold, whereas topical suspensions declined by 10%. In clinical trials, topical therapy resulted in higher remission and clinical response rates than oral therapy, with trends to earlier improvement. The mucosal concentrations of 5-ASA achieved by topical agents in the distal colon were up to 200-fold higher than those achieved by oral administration alone. Despite active colitis, over 40% of a topically administered 4 g 5-ASA suspension (equal to 1.6 g) reached the sigmoid colon. This likely represents a therapeutic exposure of 5-ASA. Although topical therapies are less convenient than oral medications, treatment algorithms have failed to take into account quality of life improvements resulting from more rapid and complete treatment response. CONCLUSIONS Topical mesalazine therapy is superior to oral therapy in distal ulcerative colitis for both therapeutic response and drug delivery. Practice patterns should be re-evaluated in light of this information.

Abstract
BACKGROUND Ulcerative proctitis (UP) is a prevalent condition associated with increased morbidity and mortality. Topical mesalamine (5-aminosalicylic acid [5-ASA]) inhibits inflammatory processes in UP. METHODS We evaluated effects of mesalamine 1-g suppository administered QHS compared with 500-mg suppository administered BID on UP activity (e.g., disease extension/mucosal appearance), remission, onset of response, safety and compliance in 97 patients with UP. A 6-week, randomized, multicenter, parallel-group, noninferiority study was conducted (and published) with Disease Activity Index (DAI) at week 6 as the primary efficacy variable and individual components of DAI at week 6 (i.e., stool frequency, rectal bleeding, mucosal appearance, global assessment) as secondary variables. Unreported outcomes were remission (DAI < 3 at weeks 3 and 6), disease extension, and complete response to treatment (DAI = 0; post-hoc, exploratory analysis). RESULTS DAI values after 6 weeks were significantly reduced (±SD) from 6.6 ± 1.5 to 1.6 ± 2.3 (500-mg BID); and from 6.1 ± 1.5 to 1.3 ± 2.2 (1-g QHS). Mucosal appearance significantly improved from baseline after 3 and 6 weeks of treatment from 1.8 ± 0.5 to 0.8 ± 0.7 and 0.5 ± 0.7 (500-mg BID; P ≤ 0.0062) and from 1.7 ± 0.5 to 0.9 ± 0.5 and 0.4 ± 0.6 (1-g QHS; P ≤ 0.0001), respectively. Remission was comparable (78.3-86.1%); onset of response generally occurred within 3 weeks, and disease extension was reduced (>70%) after 6 weeks in both groups. Mesalamine was well tolerated. Compliance was >96%. CONCLUSIONS Mesalamine 500-mg BID and 1-g QHS suppositories are safe and effective for patients with UP. Most patients reported significant improvement within 3 weeks and UP remission and reduced disease extension after 6 weeks of treatment. Validity of QHS administration was confirmed.

Abstract
Ulcerative proctitis is an idiopathic mucosal inflammatory disease involving only the rectum and is therefore an anatomically limited form of ulcerative colitis. Diagnosis is made based on clinical presentation, endoscopic appearance, and histopathology. Additionally, other etiologies of proctitis are excluded. The course of the disease is variable ranging from complete resolution to easily maintained remission to frequent relapses or refractory disease. Extension of inflammatory changes involving the proximal colon occurs in some cases. Rectal 5-aminosalicylic acid (5-ASA) or steroids are the initial treatments of choice with oral 5-ASA, sulfasalazine, or steroids used for treatment failures or patients unable to tolerate rectally administered drugs. Immunomodulators like azathioprine and 6-mercaptopurine have been used successfully in small groups of patients who have not responded to 5-ASA or steroids. Oral or rectal 5-ASA products maintain remission but long-term steroid use should be avoided. Rare cases may require surgical therapy.

Abstract
Guidelines for clinical practice are aimed to indicate preferred approaches to medical problems as established by scientifically valid research. Double-blind placebo controlled studies are preferable, but compassionate-use reports and expert review articles are used in a thorough review of the literature conducted through Medline with the National Library of Medicine. When only data that will not withstand objective scrutiny are available, a recommendation is identified as a consensus of experts. Guidelines are applicable to all physicians who address the subject regardless of specialty training or interests and are aimed to indicate the preferable but not necessarily the only acceptable approach to a specific problem. Guidelines are intended to be flexible and must be distinguished from standards of care, which are inflexible and rarely violated. Given the wide range of specifics in any health-care problem, the physician must always choose the course best suited to the individual patient and the variables in existence at the moment of decision. Guidelines are developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee and approved by the board of trustees. Each has been intensely reviewed and revised by the Committee, other experts in the field, physicians who will use them, and specialists in the science of decision analysis. The recommendations of each guideline are therefore considered valid at the time of composition based on the data available. New developments in medical research and practice pertinent to each guideline will be reviewed at a time established and indicated at publication to assure continued validity. The recommendations made are based on the level of evidence found. Grade A recommendations imply that there is consistent level 1 evidence (randomized controlled trials), grade B indicates that the evidence would be level 2 or 3, which are cohort studies or case-control studies. Grade C recommendations are based on level 4 studies, meaning case series or poor-quality cohort studies, and grade D recommendations are based on level 5 evidence, meaning expert opinion.

Abstract
Inflammatory bowel disease (IBD) describes chronic inflammatory disease of the intestines and has a variable course; Crohn's disease and ulcerative colitis comprise the two main forms of the condition. Although IBD occurs worldwide, its epidemiologic and clinical characteristics vary depending upon the geographic location and the ethnicity of the population. Identifying the characteristic features of IBD in populations living in different geographical locations and with different ethnicities may provide significant clues about its etiology and pathophysiology, which in turn may be helpful in the development of more appropriate treatment strategies for IBD for these different populations. Therefore, it is important for each country and region to evaluate critically the epidemiology, genomics, and clinical characteristics of IBD among its own population. We have performed a critical review of the recent data in Korea, and describe herein the current epidemiologic and genotypic status, as well as the clinical manifestations and therapeutic responses of IBD that are unique to Korean patients.

Abstract
5-aminosalicylic acid (5-ASA) preparations (eg, mesalazine, mesalamine) are well-established preparations used in the management of inflammatory bowel disease. These drugs are most useful for the treatment of mild to moderate flares of ulcerative colitis and, especially, for maintenance of remission. Although most gastroenterologists are very familiar with these drugs, the interest in these drugs has undergone a resurgence, with new preparations offering convenience and high dosage, while preserving their customary safety. New dosage regimens are likely to become standard practice in the near future. There is also considerable interest in chemoprevention of colorectal cancer in the context of inflammatory bowel disease, and the role of long-term maintenance therapy with 5-ASAs in achieving such chemoprevention. A mechanism of action for such chemoprevention has been provided by the agonism of the peroxisome proliferator-activated receptor-gamma by 5-ASA, which unifies its efficacy as an anti-inflammatory and chemopreventive agent. In the future, even more effective agents based on 5-ASA are expected, based on more powerful agonism of peroxisome proliferator-activated receptor-gamma; 5-ASA preparations have become 'trendy' again.

Abstract
Sulfasalazine's role as the first-line of therapy in patients with inflammatory bowel disease has led to the development of other "designer" aminosalicylates, which eliminate the sulfa-moiety, and attempt to target the topically active mesalamine to the inflamed bowel. Olsalazine sodium and balsalazide disodium utilize the same azo-bond structure as sulfasalazine, requiring release of active mesalamine by colonic bacteria, and thus targeting these agents to the colon. Other mesalamine delivery systems use pH-dependant- or moisture-release to liberate the active mesalamine in both the large and small bowel. Direct application of mesalamine via enema or suppository is also effective in patients with distal colitis. The pharmacology and thus the undesirable drug absorption rates differ between drugs, although the clinical importance of these characteristics is debatable. Differences in release-systems, the impact of the fed and fasting state, and unique patient intolerances to individual agents demand an understanding of each of these products, and their application to patient therapy.

Abstract
BACKGROUND The association of oral 5-aminosalicylic acid (mesalazine) and enema is effective in treatment of mild-moderate forms of ulcerative colitis. However no study has been aimed at determining optimal duration of this association in active ulcerative colitis. AIM To determine whether longer duration of therapy: 1. increases the rate of patients achieving remission, and 2. reduces relapse rate during the maintenance period in patients in remission. PATIENTS AND METHODS A total of 149 patients, (89 male, 60 female), were randomly assigned to a regimen with 5-aminosalicylic acid tablets 2.4 g/day associated with 5-aminosalycilic enema 2 g/day for a 4-week (n = 73) or 8-week regimen (n = 76). After this acute therapy, patients were submitted to clinical, endoscopic and histological examinations and those in remission were assigned to a follow-up (maintenance) period with oral mesalazine alone at a dosage of 1.2 g/day. A clinical visit, including laboratory tests, at 6 months and an endoscopic-histological control at 12 months were carried out to exclude symptoms and endoscopic-histological signs of activity. Relapse of disease, i.e., presence of clinical symptoms or abnormal laboratory tests, was confirmed by endoscopy and histology. RESULTS At end of acute phase, clinical, endoscopic and histological remission was comparable in the two groups: 42/76 (55%), in the 4-week, and 47/73 patients (64%), in the 8-week regimen. No difference was found stratifying patients according to extension of disease. Of these 89 patients in remission, 75 (34 from 4-week regimen; 41 from 8-week regimen) completed 12 months' follow-up. At end of follow-up, a similar percentage of patients in the 4-week regimen (50%) and 8-week regimen (51%) were still in remission. No significant difference between cumulative relapse rates of the two groups was found. Stratifying patients according to extension of disease, in the 8-week regimen group, those with left-sided colitis showed a higher remission rate than that of patients with diffuse colitis (66% versus 35%, p < 0.05). All regimens were well tolerated by most patients during the entire study period. CONCLUSIONS An additional 4 weeks of topical treatment does not increase the remission rate in patients with mild-moderate active ulcerative colitis but seems to reduce the probability of relapse in patients with left-sided colitis.

Abstract
The evolving medical armamentarium holds promise for more precise and effective therapies for IBD. The experience with anti-TNF therapy, particularly infliximab, illustrates the potential efficacy of therapies targeted at specific mediators or pathways involved in the pathogenesis. Advances in molecular technology have enabled the development of novel and potentially effective targeted therapies. Equally important is the increasing scientific understanding of the pathogenesis of IBD, which will likely improve the ability to stratify disease and to select therapies based on genotypic, immunologic, and phenotypic profiles in the future.

Abstract
Ulcerative colitis and Crohn's disease are chronic relapsing inflammatory disorders of the gastrointestinal tracts. The inflammatory process is restricted to the mucosa and submucosa of the colon in ulcerative colitis and is transmural and may occur anywhere in the gastrointestinal tract in Crohn's disease. Clinical presentation of these inflammatory disorders depends on the segments of digestive tract affected and on the extent and aggressiveness of the disease process. The treatment of specific clinical presentations of these disorders is discussed in this article.

Abstract
Crohn's disease and ulcerative colitis are idiopathic inflammatory bowel diseases characterized by dysregulated intestinal immune responses in genetically susceptible hosts. Conventional approaches to the medical therapy of ulcerative colitis and Crohn's disease can now be directed at either induction or maintenance of remission to improve therapeutic efficacy while minimizing complications. Newer approaches have expanded the utility of conventional therapies by improving both safety and efficacy and highlight the importance of specific targets along the immunoinflammatory pathways. The combination of conventional and novel approaches now offers the potential of modifying the natural history of these diseases.

Abstract
BACKGROUND Oral and topical mesalazine formulations are effective in active ulcerative colitis, but little is known on the efficacy of combined treatment. AIM To compare the efficacy of oral mesalazine vs. combined oral and topical mesalazine in mildly to moderately active ulcerative colitis. METHODS Patients with mildly to moderately active ulcerative colitis (Clinical Activity Index, CAI 4-12) were identified at 15 participating centres. They were randomized to receive either mesalazine 4 g orally plus placebo enema, or mesalazine 2 g orally plus mesalazine 2 g rectally as a liquid enema for 6 weeks. The rate of clinical remission (CAI < 4) or clinical remission/improvement (reduction of CAI of 50% from baseline) at 6 weeks and time to clinical remission/improvement were primary end-points; the rate of endoscopic remission was a secondary end-point. RESULTS 67 patients were assigned to oral treatment and 63 to combined treatment. One patient in the oral group and 2 in the combined group discontinued the treatment due to adverse events. Following an intention-to-treat analysis, the rate of clinical remission was 82% for oral treatment and 87% for combined treatment (P=0.56); the mean time to remission 22.2 and 20.2 days, respectively (P=0.29); the rate of clinical remission/improvement and the rate of endoscopic remission were 85% and 91% (P=0.503) and 58% and 71% (P=0.21), respectively. CONCLUSIONS In patients with mild active ulcerative colitis, mesalazine 4 g orally and 2 g orally plus 2 g enema are equally effective in inducing disease remission.

Abstract
Advances in the treatment of ulcerative colitis have continued to focus on improved local delivery of existing agents, such as 5-aminosalicylate and corticosteroids, and on novel immunosuppressive agents. Although newer preparations of 5-aminosalicylate continue to provide incremental benefits in safety, tolerance, and efficacy, there is a growing understanding of the limits of benefit from increasing doses. Knowledge of the safety of these agents, particularly in regard to their use in pregnancy, continues to expand. Novel corticosteroids are used in much of the world for the treatment of ulcerative colitis, with the exception of the United States, with anticipated benefits in safety but little additional therapeutic benefit. Innovative use of oral emulsion preparations of cyclosporine has been reported in the treatment of ulcerative colitis and adds to the growing body of literature on the efficacy of cyclosporine in severe disease. Relatively limited experience with other immunosuppressive agents, such as tacrolimus, has been reported. The role of antibiotics in the treatment of ulcerative colitis has continued to present controversy.

Abstract
CD and UC represent a spectrum of chronic IBD that present in protean ways and are accompanied by a variety of systemic sequelae. Sulfasalazine and the newer 5-aminosalicylates are important in the management of mild-to-moderate disease, whereas corticosteroids remain the primary therapy for most patients with moderate-to-severe disease (Tables 2-5). The toxicities associated with long-term steroid therapy, combined with their ineffectiveness as maintenance medications, have led to increased use of immunomodulators, such as azathioprine and 6-MP, for the treatment of steroid-dependent and steroid-resistant IBD. Infliximab is a novel therapeutic adjunct for chronically active and fistulizing CD that will herald a new era of biologic therapy for IBD. Meanwhile, CSA remains an alternative to urgent colectomy in severe UC unresponsive to corticosteroids and also for CD patients with severe disease or refractory fistulas. Finally, continued insights into the etiopathogenic pathways in IBD will provide evolving and innovative approaches until the eventual causes and cures are elucidated. In the meantime, clinicians should remain optimistic regarding current ability to reduce the morbidity and maintain the quality of life for patients suffering with these frustrating diseases.

Abstract
This article reviews the role of corticosteroids, sulfasalazine and mesalazine (5-aminosalicylic acid, mesalamine), immunosuppressive agents and alternative novel drugs for the treatment of distal ulcerative colitis. Short cycles of traditional, rectally administered corticosteroids (methylprednisolone, betamethasone, hydrocortisone) are effective for the treatment of mild to moderately active distal ulcerative colitis. In this context, their systemic administration is limited to patients who are refractory to either oral 5-amino-salicylates, topical mesalazine or topical corticosteroids. Of no value in maintaining remission, the long term use of either or topical corticosteroids may be hazardous. A new class of topically acting corticosteroids [budesonide, fluticasone, beclomethasone dipropionate, prednisolone-21-methasulphobenzoate, tixocortol (tixocortol pivalate)] represents a valid alternative for the treatment of active ulcerative colitis, and may be useful in the treatment of refractory distal ulcerative colitis. Although there is controversy concerning dosage or duration of therapy, oral and topical mesalazine is effective in the treatment of mild to moderately active distal ulcerative colitis. Sulfasalazine and mesalazine remain the first-choice drugs for the maintenance therapy of distal ulcerative colitis. Evidence exists showing a trend to a higher remission rate with higher doses of oral mesalazine. Topical mesalazine (suppositories or enemas) also is effective in maintenance treatment. For patients with chronically active or corticosteroid-dependent disease, azathioprine and mercaptopurine are effective in reducing either the need for corticosteroids or clinical relapses. Moreover, they are effective for long term maintenance remission. Cyclosporin may be useful in inducing remission in patients with acutely severe disease who do not achieve remission with an intensive intravenous regimen. Existing data suggest that azathioprine and mercaptopurine may be effective in prolonging remission in these patients. The role of alternative drugs for the treatment of distal ulcerative colitis and its different forms is reviewed. In particular data are reported concerning the effectiveness of 5-lipoxygenase inhibitors, topical use of short chain fatty acids, nicotine, local anaesthetics, bismuth subsalicylate enema, sucralfate, clonidine, free radical scavengers, heparin and hydroxychloroquine.
