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
Most patients with ulcerative colitis (UC) have mild-to-moderate disease activity, with low risk of colectomy, and are managed by primary care physicians or gastroenterologists. Optimal management of these patients decreases the risk of relapse and proximal disease extension, and may prevent disease progression, complications, and need for immunosuppressive therapy. With several medications (eg, sulfasalazine, diazo-bonded 5-aminosalicylates [ASA], mesalamines, and corticosteroids, including budesonide) and complex dosing formulations, regimens, and routes, to treat a disease with variable anatomic extent, there is considerable practice variability in the management of patients with mild-moderate UC. Hence, the American Gastroenterological Association prioritized clinical guidelines on this topic. To inform clinical guidelines, this technical review was developed in accordance with the Grading of Recommendations Assessment, Development and Evaluation framework for interventional studies. Focused questions included the following: (1) comparative effectiveness and tolerability of different oral 5-ASA therapies (sulfalsalazine vs diazo-bonded 5-ASAs vs mesalamine; low- (<2 g) vs standard (2-3 g/d) vs high-dose (>3 g/d) mesalamine); (2) comparison of different dosing regimens (once-daily vs multiple times per day dosing) and routes (oral vs rectal vs both oral and rectal); (3) role of oral budesonide in patients mild-moderate UC; (4) comparative effectiveness and tolerability of rectal 5-ASA and corticosteroid formulations in patients with distal colitis; and (5) role of alternative therapies like probiotics, curcumin, and fecal microbiota transplantation in the management of mild-moderate UC.

Abstract
Proctitis accounts for a significant proportion of cases of ulcerative colitis (UC), and some patients subsequently develop more extensive disease. However, most patients continue to have limited inflammation, although the changes in the distal colon and rectum can occasionally be severe, and symptoms of increased frequency, rectal bleeding and urgency can be as disabling as they are for patients with more extensive colitis. Furthermore, although symptoms are typically well controlled with standard medications, medically refractory proctitis poses particular problems. Patients generally are not systemically unwell, and there is no added fear of cancer. Therefore, the prospect of colectomy for such limited disease is resisted by patients, physicians and surgeons alike. Unusual therapies, often delivered locally by enema or suppository, have been tested in small case series without definitive outcomes. The pathogenesis of such limited, yet intractable inflammation remains unclear, and the differential diagnosis should be carefully reviewed to ensure that local disease, whether it is infectious, vascular, or a result of injury or degeneration, is not overlooked. Ileo-anal pouch formation is the surgery of choice for about 20% of patients with UC who undergo colectomy. In the majority of cases, this surgery results in an acceptable quality of life and freedom from a stoma. However, in a sizeable minority of cases, pouch dysfunction can cause intractable problems. The causes of pouch dysfunction are varied and must all be considered carefully, particularly in refractory cases. Pouchitis is a common issue and is usually transient and easily treated. However, refractory and chronic pouchitis can be challenging. Ischaemia, injury, infection and Crohn's disease can all cause refractory pouch dysfunction. In a minority of cases, there appears to be no apparent organic pathology, and the presumptive diagnosis is that of a functional pouch disorder. Although it is much rarer, neoplastic changes in the pouch must also be considered, and the risk managed appropriately. The management of both intractable proctitis and the problematic pouch is made more challenging by the wide differential diagnosis that must be considered and by the paucity of high-quality clinical trials to support any one therapy. Key strategies to overcoming these limitations include methodical and systematic investigation and review, and a willingness to tailor therapy to the individual patient. Clinical trials of new treatments should be supported, and data from the experience with small cohorts of patients should be meticulously collected, critically analysed and widely disseminated.

Abstract
BACKGROUND Sodium hyaluronate can contribute to the hydration and maintenance of the integrity of the intestinal mucosa. Restoration of the protective layer with sodium hyaluronate may contribute to the induction of remission of active ulcerative colitis. METHODS We investigated the safety and efficacy of sodium hyaluronate enema (IBD98E) in distal active ulcerative colitis, in a prospective, uncontrolled, open-label pilot trial. Subjects with active distal ulcerative colitis (UCDAI ≥ 4 and sigmoidoscopy score ≥ 1) received IBD98E 60 mL enema once a day. Primary endpoints were safety and clinical response rate at Day 28. Secondary endpoints included clinical remission, endoscopic remission, and tolerability of IBD98E. Paired Student's t-test was performed to assess statistically significant differences in subjects between baseline and Day 28. RESULTS Twenty-one subjects were enrolled. The overall safety profile was good; no serious adverse events were recorded. At Day 28, 9 subjects (42.9%) were clinical responders, and 10 subjects (47.6%) had an endoscopic response. Eight subjects (38.1%) achieved clinical remission, and 10 subjects (47.6%) achieved endoscopic remission. The mean average UCDAI score decreased from 6.10 to 3.81 at Day 28 (p=0.001), and average endoscopic score decreased from 1.57 to 1.10 (p=0.004). CONCLUSION IBD98E seems to be safe and effective for the induction of clinical and endoscopic remission. Placebo-controlled studies are warranted.

Abstract
The clinical management of ulcerative colitis (UC) involves first treating the acute symptoms to induce remission, and then successfully maintaining it. Oral 5-aminosalicylic acids are safe and useful for maintaining remission in patients with UC. In terms of adherence, a once-daily form of 5-aminosalicylic acid is superior in maintaining remission as compared with split dosing. Patients at high risk of relapse may be candidates for treatment with thiopurines and/or biologics in the early stages of UC. Calcineurin inhibitors, such as cyclosporine and tacrolimus, are effective for severe, steroid-refractory UC patients. It is suggested that these patients use thiopurines as their maintenance therapy once they achieve remission with calcineurin inhibitors. Recent studies have confirmed that biologics are effective for inducing clinical and endoscopic remission of UC, and thus they may improve long-term prognosis of UC.

Abstract
Topical therapy with mesalazine and/or corticosteroids is the standard treatment for patients with distal ulcerative colitis. Rectal mesalazine is more effective than rectal systemically active corticosteroids or topically active corticosteroids like budesonide. In patients with mild to moderately active distal ulcerative colitis, topical mesalazine is therefore the treatment of choice. Doses of 1 g or higher are equally effective. The period of treatment is important (4 weeks are more effective than 2 weeks). In the case of nonresponse or nontolerability of rectal mesalazine, rectal budesonide is indicated. The standard dose of budesonide is 2 mg/day. This does not usually induce any corticosteroid-associated adverse events. Treatment with rectal mesalazine plus rectal topically active corticosteroids is even more effective than treatment with either substance alone. To overcome adherence problems with rectal therapy, rectal foam preparations have been developed which are usually better tolerated than enemas.

Abstract
OBJECTIVES Despite a paucity of published supporting data, 5-aminosalicylate (5-ASA) use in pediatric ulcerative colitis (UC) is common. The present study describes the use and outcome of a large multicenter inception cohort of children with UC treated with 5-ASA. METHODS Data were obtained from the Pediatric Inflammatory Bowel Disease Collaborative Research Group Registry, a prospective North American observational study of children newly diagnosed as having inflammatory bowel disease ages 16 years or younger. Patient data are recorded at diagnosis, 30 days, and then quarterly. Patients are managed by physician dictate, not protocol. Disease activity is classified by physician global assessment. The primary outcome examined was corticosteroid (CS) free, inactive UC at 1 year following initiation of 5-ASA within 30 days of diagnosis (with or without concomitant CS use) without the need for rescue therapy (immunomodulators, biologics, or colectomy). RESULTS Study subjects included 213 patients newly diagnosed as having UC who received oral 5-ASA compounds (115 of whom also received CS) during the first 30 days after diagnosis, and no other oral therapies for the treatment of UC. Of these 213 patients, 86 (40%) were CS free and physician global assessment inactive at 1 year without rescue. Outcome was not associated with disease severity at diagnosis, demographic or laboratory factors examined, or initial dose of 5-ASA used. CONCLUSIONS Forty percent of children taking 5-ASA as primary maintenance therapy at diagnosis are in CS-free remission after 1 year of treatment. Further pediatric studies will be needed to address whether increased adherence and/or higher dosing schedules will improve outcomes.

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
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
OBJECTIVES Efficacy of 5-aminosalicylic acids (5-ASAs) in ulcerative colitis (UC) has been studied previously in meta-analyses. However, no recent meta-analysis has studied the relative efficacies of differing routes of administration. METHODS MEDLINE, EMBASE, and the Cochrane central register of controlled trials were searched (through May 2011). Eligible trials recruited adults with mildly to moderately active UC, or quiescent UC, and compared oral 5-ASAs with either topical 5-ASAs or a combination of oral and topical 5-ASAs. Dichotomous data were pooled to obtain relative risk (RR) of failure to achieve remission in active UC, and RR of relapse of disease activity in quiescent UC, with a 95% confidence interval (CI). The number needed to treat (NNT) was calculated from the reciprocal of the risk difference. RESULTS The search identified 3,061 citations, and 12 randomized controlled trials (RCTs) were eligible. Four compared topical with oral 5-ASAs in active UC remission, with an RR of no remission with topical 5-ASAs of 0.82 (95% CI=0.52-1.28). Four trials compared combined with oral 5-ASAs in active UC (RR of no remission=0.65; 95% CI=0.47-0.91; NNT=5). Three RCTs compared intermittent topical with oral 5-ASAs in preventing relapse of quiescent UC (RR=0.64; 95% CI=0.43-0.95; NNT=4), and two compared combined with oral 5-ASAs (RR of relapse=0.48; 95% CI=0.17-1.38). CONCLUSIONS Combined 5-ASA therapy appeared superior to oral 5-ASAs for induction of remission of mildly to moderately active UC. Intermittent topical 5-ASAs appeared superior to oral 5-ASAs for preventing relapse of quiescent UC.

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
Optimizing treatment goals in ulcerative colitis requires recognizing the needs of patients. It is increasingly recognized that adapting treatment strategies aligned with patient needs can improve patient compliance and consequently minimize relapse rates. Tailoring of treatment strategies can improve not only patient quality of life, and decrease the number harmed by adverse events from more potent drugs, but can also save valuable healthcare costs by avoiding high-cost treatment interventions associated with acute ulcerative colitis. This review will consider several elements of mesalazine management from the patient perspective based on a range of clinical and patient-focused evidence. By highlighting patient preferences in disease management it is envisaged that this review will aid physicians to optimize treatment decisions with the different mesalazine preparations available.

Abstract
To investigate how long and how much Mesalazine (M) is available inside the rectal mucosa following its topical instillation, in patients (pts) with Ulcerative Colitis (UC). Two rectal biopsies for M concentration were obtained from 45 UC pts in clinical remission and on oral M treatment (OT), before a 4g enema randomly given to consentient pts every day (Group A, 15 pts), every 2 days (Group B, 15 pts) and every 3 days (Group C, 15 pts). Two additional biopsies were taken 1, 2 and 3 days after the last enema in group A, B and C respectively, at least 10 days later. All biopsies were immediately frozen at -80°C for later assay by means of high-performance light chromatography (HPLC). Data were analyzed using Student's t-test. Mean values±standard deviation of M mucosal concentration (ng/mg of tissue) were 1.32±1.41, 56.1±39.2, 9.65±6.60, and 6.39±5.03 in pts receiving OT alone, groups A, B and C, respectively. Values in Group A were statistically higher (p<0.001) than those in Groups B and C while no differences were found between Groups B and C. Values of OT were lower than groups A, B and C. M mucosal concentration rapidly decreases 2 days after a 4g enema, but after three days is still higher than OT alone. These results may provide data which would be useful to plan topical therapy and improve adherence to treatment.

Abstract
Induction and maintenance of remission, mucosal healing, the avoidance of surgical intervention, and decreasing the likelihood of cancer developing are the primary therapeutic goals in ulcerative colitis (UC). For the traditional therapies, 5-aminosalicylic acid (including mesalamine), corticosteroids, and thiopurines (azathioprine and mercaptopurine), there are major changes evolving in terms of formulation, patterns of use, and appreciation of long-term benefits and toxicities. The calcineurin inhibitors cyclosporin and tacrolimus, and infliximab, have recently defined, well-established roles. Preliminary supportive evidence is emerging in relation to novel antiinflammatory molecules such as curcumin, manipulation of the bacterial flora, enhancement of the mucosal barrier, and direct epithelial restoration. For patients in whom the disease is resistant to standard simple therapies, strategies are required to integrate these developing and new therapies into clinical practice. This review aims to highlight the evidence supporting new patterns of use of existing therapies and new therapies, and to devise therapeutic pathways that incorporate these new treatments. We propose how treatment might be optimized to improve the outcome in patients with mild-to-moderately active UC, chronic active UC, resistant proctitis, and fulminant UC.

Abstract
BACKGROUND Ulcerative proctitis (UP) is a common presentation of ulcerative colitis (UC). OBJECTIVE To summarize available literature on up-to-date management and pharmacotherapy of UP patients. METHODS Extensive Medline/Embase literature search was performed to identify relevant articles. RESULTS/CONCLUSION Topical medication with rectally administered 5-aminosalicylic acid (5-ASA)/corticosteroid suppositories or enemas is effective treatment for most UP patients. Locally administered 5-ASA is more efficacious than oral compounds. The combination of topical 5-ASA and oral 5-ASA or topical steroids should be considered for escalation of treatment. Maintenance treatment is indicated in all UC cases. 5-ASA suppositories are suggested as first-line maintenance therapy if accepted by patients, although oral 5-ASA as maintenance therapy might prevent proximal extension of the disease. After re-assessment, chronically active patients refractory or intolerant to 5-ASAs and corticosteroids may require immunomodulators or biological therapy. Exceptional cases may require a proctocolectomy.

Abstract
BACKGROUND 5-aminosalicylic acid (5-ASA) is known to be effective in the treatment of active ulcerative colitis (UC). The aim of the current study was to investigate the effect of 5-ASA enemas, as a maintenance therapy for UC, when administered twice weekly as a weekend treatment regimen, compared to daily oral 5-ASA alone. We hypothesized that the weekend enema therapy would be better tolerated by patients who worked or attended school. METHODS Between January 2004 and August 2005, patients with UC, in whom remission of the condition had just been induced, were randomly assigned to either: the weekend 5-ASA enema group (n=11), who received 1 g 5-ASA enemas twice a week on Saturday and Sunday plus oral 5-ASA 3 g/day for 7 days, or to the daily oral 5-ASA use only group (n=13), who received only oral 5-ASA 3 g/day for 7 days. The primary endpoint of the study was defined as the incidence of relapse. The study was stopped after 24 patients had been enrolled because an interim analysis showed a significant benefit of the weekend 5-ASA enema group. RESULTS In the weekend enema group, 2 patients (18.2%) had relapses compared with 10 (76.9%) in the oral 5-ASA only group. The multivariate hazard ratio of relapse associated with weekend 5-ASA enema, relative to the oral alone group, was 0.19 (95% confidence interval, 0.04-0.94). CONCLUSIONS This study demonstrated the beneficial effects of adding weekend 1 g 5-ASA enema to daily 3 g oral 5-ASA as maintenance therapy for UC.

Abstract
BACKGROUND The goal of this work was to critically evaluate the published studies on the treatment of ulcerative proctitis (UP) and left-sided ulcerative colitis (L-UC). The results of this review provided the content for the accompanying treatment guidelines, Clinical Guidelines for the Medical Management of Left-sided Ulcerative Colitis and Ulcerative Proctitis: Summary Statement. METHODS All English language articles published between 1995 and September 2005 were identified through a comprehensive literature search using OVID and PubMed. The quality of the data supporting or rejecting the use of specific therapies was categorized by a data quality grading scale. An "A+" grade was assigned to treatment supported by multiple high-quality randomized controlled trials with consistent results, whereas a "D" grade was given to therapy supported only by expert opinion. The therapeutic efficacy of a treatment was defined by its success in treating UP and L-UC compared with placebo. A medication was ranked as "excellent" if it was specifically studied for UP and L-UC and had consistently positive results compared with placebo or another agent. Quality and efficacy scores were agreed on by author consensus. RESULTS For the acute treatment of UP or L-UC, the rectally administered corticosteroids and mesalazine (5-ASA), either alone or in combination with oral 5-ASAs, are the most effective therapy: evidence quality, A+; efficacy, excellent. Only rectally administered 5-ASA received an A+/excellent rating for maintenance of remission. Infliximab received an A+ grade for induction and maintenance of remission but only a "good" rating because the studies were performed in all UC, not specifically UP or L-UC. CONCLUSIONS This critical evaluation of treatment provides a "report card" on medications available for the management of patients with UP and L-UC. The guidelines should provide a useful reference and supplement for physicians treating UC patients.

Abstract
BACKGROUND Mesalazine is among the medications most commonly prescribed by gastroenterologists, having to a large extent superseded sulfasalazine (sulphasalazine). However, there are still a number of aspects regarding its use which provoke debate and controversy. AIM To provide a systematic assessment of the evidence for the use of mesalazine in ulcerative colitis and Crohn's disease. METHODS References were identified using PubMed database. Additional references were identified with related article searches. RESULTS Mesalazine has a clear role in the maintenance of remission in ulcerative colitis and management of mild to moderately active disease, although the efficacy of topical preparations or combined topical and oral is clearly superior to oral alone. Evidence that increasing the dose of oral mesalazine improves efficacy is not clear-cut. The benefits of mesalazine in the management of acute Crohn's disease and the maintenance of remission are questionable and alternative treatments are usually more appropriate. Emerging evidence suggests that maintenance mesalazine reduces the risk of neoplastic progression in chronic ulcerative colitis. Compliance with therapy is thus important, as is an understanding of individuals most likely to default on this. CONCLUSION Evidence for a beneficial effect of mesalazine is largely confined to the management of ulcerative colitis.

Abstract
OBJECTIVES Studies aimed at establishing which characteristics of patients with ulcerative proctitis could be predictive of the extension of inflammation have failed to provide conclusive results. The aim of the study was to evaluate the prognostic role of clinical and therapeutic parameters in patients with proctitis. PATIENTS AND METHODS Case records of 138 patients with ulcerative proctitis were retrospectively evaluated. The following parameters were considered: gender; age at onset of disease; smoking habits; histologic severity of disease at onset; mean number of clinical relapses of disease per year; mean duration of oral and topical mesalazine treatment; and number of topical corticosteroid treatments per year. RESULTS Twenty-eight patients were excluded from the analysis for different reasons. During follow-up, inflammation spread proximally in 33 of 110 patients (30%). Patients with extended proctitis showed a significantly higher number of relapses and a shorter duration of oral mesalazine treatment than patients with nonprogressive proctitis (p < 0.001 for both). The multivariate analysis also found that the mean duration of topical mesalazine treatment was longer in patients with extended proctitis. CONCLUSIONS Ulcerative proctitis patients with more frequent relapses who need a longer duration of topical therapy are at higher risk of extension of the disease, while a more prolonged oral mesalazine treatment period protects against the proximal spread of rectal inflammation.

Abstract
Proctitis refers to inflammation of the rectum, a diagnosis made by endoscopic evaluation. Symptoms of proctitis include rectal bleeding, urgency, tenesmus, diarrhea or constipation, and occasionally rectal pain. The causes of proctitis include infection, medication, ischemia, radiation, and ulcerative proctitis. Ulcerative proctitis is an important and increasingly common subcategory of ulcerative colitis (UC) in which inflammation is limited to the rectum. Historically, oral aminosalicylates have been the mainstay of acute and maintenance therapy. A growing body of data, however, indicates that topical aminosalicylates are effective first line agents in ulcerative proctitis and distal UC. Topical aminosalicylates act more effectively and rapidly to induce and maintain remission compared with their oral counterparts or topical steroids. Rarely ulcerative proctitis is refractory to topical therapy and in these instances systemic corticosteroids, antibiotics, immunomodulators, or surgery is required. This review highlights the pathogenesis, diagnosis, and treatment of ulcerative proctitis.

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
Oral aminosalicylates such as sulfasalazine and mesalamine are widely prescribed for the treatment of mild or moderately active distal ulcerative colitis. However, a critical review of the literature demonstrates that rectal 5-aminosalicylic acid (5-ASA) is the optimal therapy for this disease. Meta-analyses of published trials show that rectally delivered 5-ASA is superior to placebo and to conventional rectal corticosteroids in inducing remission of distal ulcerative colitis, whereas the combination of rectal 5-ASA with a rectal corticosteroid or oral aminosalicylate is superior to rectal 5-ASA alone. For maintaining remission of distal ulcerative colitis, rectal 5-ASA is significantly better than placebo and at least as effective as oral 5-ASA. The dosage forms available for rectal delivery include suppositories, foams, and liquid enemas, and selection among these preparations should be guided by the proximal extent of disease and patient preference. The efficacy of rectal 5-ASA is complemented by its low rate of reported adverse effects, which may reflect its reduced potential for systemic absorption. This review summarizes the evidence supporting the role of rectal 5-ASA as a first-line therapy for mild or moderately active distal ulcerative colitis, and offers guidelines for its use.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of a single nightly 500-mg Rowasa (mesalamine) suppository as maintenance therapy for patients with ulcerative proctitis in remission. METHODS In this 24-month, multicenter, double-blind trial, 65 patients with ulcerative proctitis in clinical and endoscopic remission were randomized to receive either a single nightly 500-mg rectal mesalamine (Rowasa) suppository or matching placebo as sole therapy. Efficacy was assessed by time to relapse (defined as rectal bleeding or increase in stool frequency for > or =1 wk and active inflammation upon endoscopy). RESULTS Mean time to relapse was 453.4 days for mesalamine-treated patients and 158.0 days for placebo-treated patients. Survival analysis demonstrated that time to relapse was significantly greater for mesalamine-treated patients than for placebo-treated patients (p < 0.001). In addition, at both 12 and 24 months, the proportion of placebo-treated patients (86% at 12 months and 89% at 24 months) who relapsed was significantly (p < or = 0.001) greater than mesalamine-treated patients (32% and 46%, respectively). No statistically significant differences occurred between treatment groups in the reporting of any particular adverse event or the number of patients reporting adverse events. CONCLUSIONS The results demonstrate that mesalamine suppositories are efficacious, well tolerated, and safe for the long-term maintenance of remission of ulcerative proctitis.

Abstract
AIMS Tissue concentrations of 5-aminosalicylic acid (5ASA) and its metabolites may influence the clinical course of inflammatory bowel disease. Since the factors that determine tissue drug concentrations are unknown we have studied the relationships between the oral dose of delayed-release mesalazine, rectal tissue drug concentrations and standard pharmacokinetic parameters. METHODS Twelve healthy volunteers were studied following 7 days treatment with 1.2, 2.4 and 4.8 g of delayed-release mesalazine daily. 5-aminosalicylic acid and N-acetyl 5-aminosalicylic acid concentrations were measured in serum, urine, stool and rectal tissue biopsies. RESULTS Serum concentrations and 24 h urinary excretion of 5ASA and N-acetyl 5ASA increased as the oral dose of mesalazine was increased from 1.2 g through 2.4 g to 4.8 g daily (serum area under curve (AUC):5ASA = 3. 9, 15.4 and 46.8 microg ml-1 h, P < 0.0001; N-acetyl 5ASA = 17.2, 30. 9 and 57.8 microg ml-1 h, P < 0.0001: urinary excretion: 5ASA = 1.8, 85.5 and 445 mg, P < 0.0001; N-acetyl 5ASA = 250, 524 and 1468 mg, P < 0.0001, respectively). Faecal 5ASA excretion increased as the oral dose increased from 1.2 g to 2.4 g but did not increase further with 4.8 g daily dosing whereas faecal N-acetyl 5ASA excretion was similar at all three doses. Rectal tissue concentrations of 5ASA increased markedly, and N-acetyl 5ASA increased modestly, as the dose of oral mesalazine increased from 1.2 g to 2.4 g daily but neither increased further with 4.8 g daily dosing. CONCLUSIONS The relationship between the ingested dose of delayed-release mesalazine and rectal tissue drug concentrations is complex. Factors other than dose are likely to be important determinants of rectal tissue drug concentrations.

Abstract
A pluridisciplinary approach that integrates medical therapy with surgery and other aspects of patient care, such as nutritional and psychosocial support, is essential to the management of patients with inflammatory bowel disease (IBD). Despite new medical therapies, such as 5-amino-salicylic acid compounds, steroids, and immunomodulators, the treatment of patients with IBD remains challenging. Success depends on the appropriate use of the available medications in relation to the severity and localization of the disease. The introduction of novel immunomodulating agents such as antitumor necrosis factor alpha is likely to have a major influence on the current therapeutic strategies. This article describes the use of the available medications in the most common clinical presentations of IBD.

Abstract
OBJECTIVES A multicenter double-blind placebo-controlled clinical study was conducted to evaluate the efficacy and tolerability of two different therapeutic schedules of mesalazine suppositories in patients with ulcerative proctitis. METHODS From 1990 to 1993, 111 patients with ulcerative proctisis in remission, limited to the rectum (< or = 15 cm from anus), were enrolled. After obtaining informed consent, patients were randomized to three treatment groups: 500 mg mesalazine b.i.d. (36 patients), 500 mg mesalazine u.i.d. (40 patients), and placebo (35 patients). The treatment lasted 1 yr. Follow-up consisted of periodic clinical, endoscopic, and histological assessments. An endoscopic score > 1 according to the Baron scale defined relapse occurrence. The three groups were homogeneous as regards main demographic, diagnostic, and prognostic features. RESULTS The cumulative relapse rates at 12 months were 10% (95% confidence interval [CI]: 0-21) in the mesalazine b.i.d. group, 32% (95% CI: 16-49) in the mesalazine u.i.d. group, and 47% (95% CI: 29-65) in the placebo group. The comparison between the mesalazine b.i.d. group and the mesalazine u.i.d. group cumulative relapse rates gave a p value of 0.0334, whereas the corresponding comparison between the mesalazine b.i.d. group and the placebo group gave a p value of 0.007 (log-rank test). The dose-response relationship was statistically significant (p = 0.008 by Cox analysis). Two patients in the mesalazine b.i.d. group, two patients in the mesalazine u.i.d. group, and one patient in the placebo group withdrew from the study due to nonserious adverse events; four, three, and four patients per group, respectively, dropped out because of poor compliance. Two patients in the mesalazine u.i.d. group and two in the placebo group were lost to follow-up. CONCLUSIONS The results of this study confirm the therapeutic efficacy of mesalazine suppositories in the maintenance treatment of ulcerative proctitis. According to our experience the most effective therapeutic schedule is 500 mg mesalazine b.i.d.

Abstract
BACKGROUND Daily administration of rectal formulations of mesalazine is effective in preventing relapse of ulcerative proctitis. Maintenance of remission with lower doses would be an advantage. AIM The efficacy of mesalazine suppositories (Pentasa) 1 g three times a week v placebo to maintain remission in patients with cryptogenetic proctitis was studied. METHODS Ninety five patients with cryptogenetic proctitis were randomised within two weeks of remission to receive for one year or until relapse three suppositories per week of either Pentasa (n = 48) or placebo (n = 47). In the case of a relapse, the patients received one suppository/day. RESULTS It was found that 25 of 48 subjects v 18 of 47 remained in remission in the mesalazine and placebo groups respectively. The relapse rate was lower in the mesalazine group for the following time intervals: 0-90 days (19% v 38%, p = 0.035), 0-180 days (29% v 54%, p = 0.017), 0-270 days (38% v 60%, p = 0.031), and 0-365 days (48% v 62%, p = 0.18). Treatment of relapse with one suppository/day induced remission in 11 of 18 and 2 of 26 patients in the mesalazine and placebo groups respectively (p = 0.001). Overall, 61% v 28% patients remained in the protocol and were in remission at one year (p = 0.001). Tolerance was good. CONCLUSION Mesalazine suppositories 1 g three times a week are effective for preventing relapses of cryptogenetic proctitis. Increasing the dose to 1 g/day is effective in a high proportion of subjects who relapsed.

Abstract
Topical therapy can be considered the standard treatment for distal ulcerative colitis. The group of drugs of first choice are the aminosalicylates which are effective in inducing remission in acute disease as well as in preventing relapse. Corticosteroids appear to be slightly less effective and have no proven benefit in maintenance therapy. With new topical steroids, such as budesonide, systemic effects can be minimized. The major role of corticosteroids is to complement aminosalicylates, when necessary. The new topical compounds appear to be especially valuable when there is a long-term requirement for corticosteroids. With the vast majority of patients obtaining remission with standard treatment, it is difficult to make the case for alternative substances. Short-chain fatty acids, local anaesthetics and bismuth compounds seem to be the most promising innovations in topical therapy although their equivalence or even superiority to mesalazine has not been established.

Abstract
BACKGROUND To summarize and quantify the evidence supporting rectal 5- or 4-aminosalicylate (ASA) therapies for disease exacerbation or remission maintenance in distal ulcerative colitis, we performed a meta-analysis. METHODS All randomized, double-blind controlled trials involving aminosalicylate therapy were retrieved from a MEDLINE search, review articles on ulcerative colitis therapy or their bibliographies. Of 55 studies retrieved, 19 met the inclusion criteria. Appraisal and data extraction were performed by two observers and scoring disagreements were resolved by consensus. RESULTS Eleven trials tested 5-ASA and three tested 4-ASA in active ulcerative colitis. 5-ASA was superior to placebo for inducing remission or symptomatic improvement in active ulcerative colitis with a pooled odds ratio of 7.36 (95% Confidence interval (CI): 4.72-11.47). In four trials the pooled odds ratio for endoscopic improvement was 10.04 (95% CI: 5.72-17.61) and for histological improvement 10.31 (95% CI: 5.85-18.18). Studies evaluating 4-ASA suggest a benefit similar to prednisolone in treating active disease. Five trials assessed remission maintenance with 5-ASA, and when compared to placebo gave a pooled odds ratio of 16.22 (95% CI: 4.71-55.92). No dose-response relationship was observed. ASA compounds were not therapeutically superior to other treatments. CONCLUSIONS We conclude that rectal 5-ASA is effective therapy for active distal ulcerative colitis. More trials are needed to assess 4-ASA, dose-response effects and the ideal regimen for remission maintenance.
