The Ulcerative Colitis Endoscopic Index of Severity More Accurately Reflects Clinical Outcomes and Long-term Prognosis than the Mayo Endoscopic Score. J Crohns Colitis 2016; 10:286-95.

Abstract
BACKGROUND AND AIMS The Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and the Mayo endoscopic score (Mayo ES) are used to evaluate ulcerative colitis (UC) severity. This study compared UCEIS and the Mayo ES for evaluating UC severity and outcomes in patients undergoing remission induction during routine clinical practice with the aim of predicting medium- to long-term prognosis. METHODS Forty-one UC patients who received colonoscopy before and after tacrolimus remission induction therapy were included. An index of clinical activity and endoscopic findings scored by both the UCEIS and the Mayo ES were determined. Changes in UCEIS and Mayo ES before and after induction therapy were compared. RESULTS The mean UCEIS improved from 6.2±0.9 to 3.4±2.1 (p < 0.001). Based on the UCEIS, a significant reduction was reached in both the response and the remission groups. In contrast, the Mayo ES did not reflect a significant change in the response group. The discrepancy appeared to be due to ulcers becoming smaller and shallower during the early stages of mucosal healing; the Mayo ES seems to miss these early changes. In other words, whereas the UCEIS indicates improvements when ulcers shrink, the Mayo ES does not distinguish deep ulcers from shallow ulcers and is 3 (severe UC) for both deep and shallow ulcers. Additionally, better UCEIS strata after induction therapy were associated with lower incidences of colectomy (p = 0.0001) or relapse (p = 0.0008). CONCLUSIONS The UCEIS accurately reflects clinical outcomes and predicts the medium- to long-term prognosis in UC patients undergoing induction therapy. These findings should support decision-making in clinical practice settings.

A Comparison of Short- and Long-Term Therapeutic Outcomes of Infliximab- versus Tacrolimus-Based Strategies for Steroid-Refractory Ulcerative Colitis. Gastroenterol Res Pract 2016; 2016:3162595. [PMID: 26904108 PMCID: PMC4745932 DOI: 10.1155/2016/3162595] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2015] [Revised: 12/24/2015] [Accepted: 01/03/2016] [Indexed: 12/16/2022] Open
Abstract
Background/Aims. Antitumor necrosis factor antibodies and calcineurin inhibitors have shown good therapeutic efficacy for steroid-refractory ulcerative colitis (UC). Although some studies have compared the efficacy of infliximab (IFX) and cyclosporin A, there are no published studies comparing IFX and tacrolimus (Tac). This study aimed to compare therapeutic efficacies between IFX- and Tac-based strategies for steroid-refractory UC. Methods. Between July 2009 and August 2013, 95 patients with steroid-refractory UC received either IFX (n = 48) or Tac (n = 47) in our hospital. In the IFX group, the patients continued to receive maintenance treatment with IFX. In the Tac group, patients discontinued Tac treatment up to 3 months and subsequently received thiopurine. We retrospectively compared the therapeutic outcomes between the groups. Results. There was no significant difference in the colectomy-free rate, clinical remission rate, and clinical response rate at 2 months between the groups. However, relapse-free survival was significantly higher in the IFX group than in the Tac group (p < 0.001; log-rank test). The proportions of serious adverse events did not differ between the groups. Conclusion. The findings of our study showed that IFX and Tac have similar short-term therapeutic efficacy for steroid-refractory UC. Maintenance treatment with IFX, however, yields better long-term outcomes than Tac-thiopurine bridging treatment.

Abstract
BACKGROUND AND AIMS Tacrolimus is recommended for the treatment of steroid-refractory ulcerative colitis (UC). Concomitantly started purine analogues (PAs) are used for the maintenance of remission, though their therapeutic relevance remains uncertain. Here we studied the role of PAs in the long-term outcome of steroid-refractory UC after tacrolimus treatment. METHODS In five centres, charts of tacrolimus-treated UC patients with a steroid-refractory moderate to severe course were reviewed. Long-term efficacy was determined by colectomy rates and clinical remission in cases of colectomy-free survival for 3 months. RESULTS We identified 156 patients (median age 34 years) with a median Lichtiger score of 12 (4-17) and pancolitis (E3) in 65% (101). The Kaplan-Meier curve for colectomy-free survival after month 3 showed a benefit in the PA group (p = 0.02). In patients treated with PA clinical remission was achieved in 82% (65/79) vs 67% (39/58) in those not treated with PA (p = 0.02). Time to colectomy was 2 years (median, 0.7-5.8) in the PA group and 0.8 years (0.3-4.7) in the group not treated with PAs (p = 0.02). Time to relapse was 1.2 years (median, 0.3-6.2) in patients with PA treatment and 0.5 years (0.3-3.9) in those without PA treatment (p = 0.05). Overall, clinical remission was achieved in 67% (104/156) of patients. Colectomy was performed in 29% (45/156) 0.5 years (median, 0.04-5.79) after initiation of tacrolimus. Ten (6%) patients had to stop tacrolimus due to adverse events and two (without PA treatment) died. CONCLUSIONS Our study supports the efficacy of tacrolimus in steroid-refractory UC. Purine analogues appear to be beneficial for the long-term outcome of these patients.

Abstract
Compromised intestinal barrier function is a prominent feature of inflammatory bowel disease (IBD). However, links between intestinal barrier loss and disease extend much further, including documented associations with celiac disease, type I diabetes, rheumatoid arthritis, and multiple sclerosis. Intestinal barrier loss has also been proposed to have a critical role in the pathogenesis of graft-versus-host disease (GVHD), a serious, potentially fatal consequence of hematopoietic stem cell transplantation. Experimental evidence has begun to support this view, as barrier loss and its role in initiating and establishing a pathogenic inflammatory cycle in GVHD is emerging. Here we discuss similarities between IBD and GVHD, mechanisms of intestinal barrier loss in these diseases, and the crosstalk between barrier loss and the immune system, with a special focus on natural killer (NK) cells. Unanswered questions and future research directions on the topic are discussed along with implications for treatment.

Abstract
Tacrolimus is a calcineurin inhibitor used for the treatment of corticosteroid-refractory ulcerative colitis (UC). Two randomized controlled trials and a number of retrospective studies have assessed the therapeutic effect of tacrolimus in UC patients. These studies showed that tacrolimus has excellent short-term efficacy in corticosteroid-refractory patients, with the rates of clinical response ranging from 61% to 96%. However, the long-term prognosis of patients treated with tacrolimus is disappointing, and almost 50% of patients eventually underwent colectomy in long-term follow-up. Tacrolimus can achieve mucosal healing in 40-50% of patients, and this is associated with a favorable long-term prognosis. Anti-tumor necrosis factor (TNF)-α antibodies are another therapeutic option in corticosteroid-refractory patients. A prospective head-to-head comparative study of tacrolimus and infliximab is currently being performed to determine which treatment is more effective in corticosteroid-refractory patients. Several retrospective studies have demonstrated that switching between tacrolimus and anti-TNF-α antibody therapy was effective in patients who were refractory to one of the treatments. Most adverse events of tacrolimus are mild; however, opportunistic infections, especially pneumocystis pneumonia, are the most important adverse events, and these should be carefully considered during treatment. Several issues on tacrolimus treatment in UC patients remain unsolved (e.g., use of tacrolimus as remission maintenance therapy). Further controlled studies are needed to optimize the use of tacrolimus for the treatment of UC.

Abstract
BACKGROUND Although the pathogenesis of pouchitis is incompletely understood, steroid and FK506 therapy are significantly associated with pouchitis. These medical treatments are regulated by the FK506-binding protein (FKBP) 4 and FKBP5 genes. AIM This study aimed to evaluate the relationship between pouchitis and FKBP4 and FKBP5 mRNA expression in ileal mucosa at the time of colectomy. METHODS Ileal mucosa specimens were collected from 71 patients who underwent ileal pouch-anal anastomosis for ulcerative colitis. FKBP4 and FKBP5 mRNA expression was evaluated. The relationship between mRNA expression and clinicopathological factors, including developed pouchitis, was investigated. RESULTS Of these 71 patients, 25 (35.2 %) patients developed pouchitis in a mean duration of 20.2 months (range 0-68 months). FKBP4 mRNA levels in patients who received an immunomodulator were significantly higher than those in untreated patients (0.167 ± 0.060 vs 0.131 ± 0.065, p = 0.009). However, FKBP5 mRNA levels in patients who received a three-stage operation were significantly lower than those in the other patients (1.97 ± 1.15 vs 2.70 ± 1.12, p = 0.02). A total dose of prednisolone >9.4 g (HR 2.84, p = 0.02) before colectomy and FKBP5 mRNA level higher than the median (HR 4.49, p = 0.01) were identified as factors related to pouchitis. CONCLUSIONS FKBP5 mRNA levels in ileal mucosa at the time of colectomy are significantly associated with pouchitis and may be a predictive factor for developing pouchitis.

Abstract
BACKGROUND Tacrolimus has shown efficacy in patients with ulcerative colitis. AIMS To evaluate the efficacy of tacrolimus as remission induction therapy and assess medium to long-term outcomes in patients who achieve remission. METHODS Forty-four ulcerative colitis patients who were treated with tacrolimus in three institutes during 2009-2013 were retrospectively reviewed. Short-term efficacy was based on the clinical activity index and the Mayo endoscopic subscores. Clinical activity index≤4 meant clinical remission, while Mayo endoscopic subscore 0 or 1 meant mucosal healing. Medium to long-term prognosis was based on relapse free survival in relation to the Mayo endoscopic subscore and duration of tacrolimus therapy in patients who achieved remission. RESULTS At 12 weeks, clinical remission was achieved in 29 of 44 patients (65.9%). Thirty-two patients received endoscopic evaluations, and mucosal healing rate was 43.8%. Among patients with clinical remission, mucosal healing rate was 60.9%. Relapse-free survival at 6, 12, and 24 months were 66%, 56%, and 50%, respectively, and was higher in patients on long-term tacrolimus (over 4 months, P=0.03), and patients with better endoscopic subscore (P=0.009). CONCLUSIONS Mucosal healing observed within 12 weeks or after a longer duration of tacrolimus therapy was associated with significantly better remission maintenance time.

Abstract
BACKGROUND Several open-label and retrospective studies have indicated that thalidomide may be beneficial in patients with refractory Crohn's disease (CD). AIM To report our long-term experience with the use of thalidomide for adults with refractory Crohn's disease. METHODS We conducted a retrospective study of long-term clinical and safety outcomes among adults treated with thalidomide for refractory Crohn's disease. Response was defined as a clinician's assessment of improvement after at least 7 days treatment of one or more of the following: bowel movement frequency, fistula output, rectal bleeding, abdominal pain, extraintestinal manifestations, or well-being. Remission required all of the following: <3 stools/day, no bleeding, abdominal pain or extraintestinal manifestations and increased well-being. RESULTS Thirty-seven adults with refractory Crohn's disease were treated with thalidomide for a median of 4.4 months and followed up for a median of 58 months. Clinical response and remission rates were 54% and 19%, respectively. About 40% of patients were able to stop steroids. Response rates were higher for those treated with more than 50 mg/day (85%) than for those treated with a maximum of 50 mg/day (40%; P = 0.01). An adverse event occurred in 68% of patients. Approximately one-third of patients (38%) experienced neuropathy. CONCLUSIONS Thalidomide appears to be safe and effective in some patients with refractory Crohn's disease. Although side effects may limit long-term use, thalidomide has potential to induce significant clinical responses.

Abstract
Objective Treatment of severe ulcerative colitis (UC) is challenging. Although the efficacy of tacrolimus (TAC) and infliximab (IFX) have been evaluated in patients with severe UC, the safety and efficacy levels of sequential therapies (TAC→IFX/IFX→TAC) in these patients remain unclear. The aim of this study was to assess short-term and long-term outcomes in patients with severe UC treated with TAC and IFX. Methods From October 2001 to February 2014, 29 patients with consecutive severe UC treated with TAC or IFX were retrospectively evaluated. Median follow-up duration was 27 months (range 0.5–118 months). The primary end point was short-term outcomes at 8 weeks after induction of TAC (TAC group, n=22) or IFX (IFX group, n=7). The secondary end point included long-term outcomes and colectomy-free survival. The clinical response was evaluated based on a partial Mayo score. Results The clinical remission (CR) rate at 8 weeks in the TAC and IFX groups was 63.6% and 71.4%, respectively. In 13 of the 29 patients (10 in the TAC group, 3 in the IFX group), sequential therapies were used in their clinical courses. In 9 of these 13 patients (6 in the TAC group, 3 in the IFX group), CR was achieved and maintained by sequential therapies. Overall cumulative colectomy-free survival was 79.3% at 118 months. Conclusions TAC and IFX had similar effects on remission induction in patients with severely active UC. Sequential therapies could rescue patients with UC who failed initial treatment with TAC or IFX. In clinical practice, sequential therapies might be deliberately performed.

Abstract
The management strategy of acute severe ulcerative colitis has evolved over the past decade from being entirely restricted to twin choices of intravenous steroids or colectomy to include colon rescue therapies like cyclosporin as well as infliximab. However it still remains a medical emergency requiring hospitalization and requires care from a multidisciplinary team comprising of a gastroenterologist and a colorectal surgeon. The frame shift in management has been the emphasis on time bound decision making with an attempt to curtail the mortality rate to below 1%. Intravenous corticosteroids are the mainstay of therapy. Response to steroids should be assessed at day 3 of admission and partial/non-responders should be considered for alternative medical therapy/surgery. Medical rescue therapies include intravenous cyclosporin and infliximab. Cyclosporin is administered in a dose of 2 mg/kg per day and infliximab is administered as a single dose intravenous infusion of 5 mg/kg. Approximately 75% patients have short term and 50% patients have long term response to cyclosporin. Long term response to cyclosporin is improved in patients who are thiopurine naïve and are started on thiopurines on day 7. Infliximab also has a response rate of approximately 70% in short term and 50% in long term. Both cyclosporin and infliximab are equally efficacious medical rescue therapies as demonstrated in a recent randomized control trial. Patients not responding to infliximab or cyclosporin should be considered for colectomy.

Abstract
Ulcerative colitis and Crohn's disease, which is the 2 major forms of inflammatory bowel disease, are chronic relapsing and remitting inflammatory disorder of the gastrointestinal tract. During the last 30 years, the therapy for patients with refractory inflammatory bowel diseases is still challenging despite the fact that morbidity and mortality rates have been obviously reduced. The conventional management with corticosteroids has been modified by the introduction of calcineurin inhibitors and biologics. In this review, we focus on role in calcineurin inhibitors for patients with inflammatory bowel disease in the currently clinical practice.

Abstract
Ulcerative colitis (UC)-associated pan-enteritis is a newly identified clinical entity that occurs almost exclusively after colectomy. Characterized by diffuse small bowel mucosal inflammation not compatible with Crohn's disease, the optimal treatment modality for this condition is unknown. Tacrolimus is a potent calcineurin inhibitor that has been successfully used in the treatment of UC. We describe a case of severe refractory pan-enteritis after colectomy for UC that was successfully treated with oral tacrolimus after failing intravenous corticosteroid treatment. Tacrolimus may be a safe and effective treatment modality for diffuse enteritis after colectomy in UC patients.

Abstract
BACKGROUND Tacrolimus in refractory ulcerative colitis often serves as a bridge to long-term maintenance therapy with thiopurines. Our aim was to review efficacy and safety of tacrolimus in active ulcerative colitis resistant to conventional therapies, including anti-tumour necrosis factor. METHODS Charts of consecutive outpatients with refractory ulcerative colitis, in whom tacrolimus was orally administered as a 12 week-induction (target trough levels 10-15ng/mL) followed by a maintenance therapy (target trough levels 5-10ng/mL), were retrospectively reviewed. Clinical remission and response at weeks 4, 12 and 52 as well as adverse events within 1-year therapy were reported. RESULTS Twelve (40%) and six (20%) of the 30 patients included (14 males, mean age 37.1±1.4 years) achieved a clinical remission and response, respectively, at week 12. Three responders to tacrolimus initiation experienced drug-related adverse events requiring discontinuation. Among the 18 remaining initial responders who tolerated tacrolimus, 8 (27%) were in clinical remission at week 52, whereas the remainder either experienced adverse events requiring drug withdrawal (n=4) or relapsed (n=6). Overall adverse events were recorded in 14 patients (46%), mainly finger tremor and urinary infections. CONCLUSION Oral monotherapy with tacrolimus may be a valuable long-term therapeutic option in selected patients with moderate-to-severe active refractory ulcerative colitis.

Abstract
To date, corticosteroids have been the primary therapies for acute, severe ulcerative colitis (UC). Patients not responding to intravenous steroids assessed at 3-5 days of the treatment are candidates for second-line rescue therapy. Cyclosporine (CsA), tacrolimus and infliximab (IFX) are also effective therapeutic options in acute, severe UC. In this review we summarized the results of the published studies examining and comparing the efficacy of CsA, tacrolimus and IFX as rescue therapies, and assessing the outcome of switching the drugs in case of therapeutic failure.

Abstract
Ulcerative colitis (UC) is an idiopathic, inflammatory gastrointestinal disease of the colon. As a chronic condition, UC follows a relapsing and remitting course with medical maintenance during periods of quiescent disease and appropriate escalation of therapy during times of flare. Initial treatment strategies must not only take into account current clinical presentation (with specific regard for extent and severity of disease activity) but must also take into consideration treatment options for the long-term. The following review offers an approach to new-onset UC with a focus on early treatment strategies. An introduction to the disease entity is provided along with an approach to initial diagnosis. Stratification of patients based on clinical parameters, disease extent, and severity of illness is paramount to determining course of therapy. Frequent assessments are required to determine clinical response, and treatment intensification may be warranted if expected improvement goals are not appropriately reached. Mild-to- moderate UC can be managed with aminosalicylates, mesalamine, and topical corticosteroids with oral corticosteroids reserved for unresponsive cases. Moderate-to-severe UC generally requires oral or intravenous corticosteroids in the short-term with consideration of long-term management options such as biologic agents (as initial therapy or in transition from steroids) or thiopurines (as bridging therapy). Patients with severe or fulminant UC who are recalcitrant to medical therapy or who develop disease complications (such as toxic megacolon) should be considered for colectomy. Early surgical referral in severe or refractory UC is crucial, and colectomy may be a life-saving procedure. The authors provide a comprehensive evidence-based approach to current treatment options for new-onset UC with discussion of long-term therapeutic efficacy and safety, patient-centered perspectives including quality of life and medication compliance, and future directions in related inflammatory bowel disease care.

Abstract
BACKGROUND We previously demonstrated that antibiotic combination therapy is effective for induction and maintenance of ulcerative colitis (UC) remission. AIM To assess whether antibiotic combination therapy is effective for active UC refractory to or dependent on steroids in a multicentre, open-label trial. METHODS We enrolled 30 patients with steroid-refractory and 64 with steroid-dependent active UC. These patients received three-times-daily by mouth amoxicillin 500 mg, tetracycline 500 mg and metronidazole 250 mg, for two weeks, as well as conventional treatment. Symptom assessment and colonoscopic evaluation were performed before enrolment and at 3 and 12 months after treatment completion. Clinical response was defined as a Lichtiger symptom score decrease in ≥3 points and clinical remission as a score ≤4. RESULTS Nineteen of the 30 steroid-refractory (63.3%) and 47 of the 64 steroid-dependent (73.4%) patients showed a clinical response within 2 weeks. At 3 and 12 months, 60% and 66.6% of steroid-refractory patients, and 56.3% and 51.6% of steroid-dependent patients, respectively, achieved clinical remission. In the steroid-dependent group, 39 of the 64 patients (60.9%) were able to stop steroid therapy and remained in remission for 3 months. Three (10%) steroid-refractory and four (6.3%) steroid-dependent patients underwent colectomy. CONCLUSIONS This multicentre, long-term follow-up study suggests 2 week antibiotic combination therapy to be effective and safe in patients with active UC refractory to or dependent on steroids.

Abstract
The inflammatory bowel diseases (IBDs) are chronic incurable conditions that primarily present in young patients. Being incurable, the IBDs may be part of the patient’s life for many years and these conditions require therapies that will be effective over the long-term. Surgery in Crohn’s disease does not cure the disease with endoscopic recurrent in up to 70% of patients 1 year post resection. This means that, the patient will require many years of medications and the goal of the treating physician is to induce and maintain long-term remission without side effects. The development of the anti-tumour necrosis factor alpha (TNFα) agents has been a magnificent clinical advance in IBD, but they are not always effective, with loss of response overtime and, at times, discontinuation is required secondary to side effects. So what options are available if of the anti-TNFα agents can no longer be used? This review aims to provide other options for the physician, to remind them of the older established medications like azathioprine/6-mercaptopurine and methotrexate, the less established medications like mycophenolate mofetil and tacrolimus as well as newer therapeutic options like the anti-integins, which block the trafficking of leukocytes into the intestinal mucosa. The location of the intestinal inflammation must also be considered, as topical therapeutic agents may also be worthwhile to consider in the long-term management of the more challenging IBD patient. The more options that are available the more likely the patient will be able to have tailored therapy to treat their disease and a better long-term outcome.

Abstract
BACKGROUND AND AIM The pharmacokinetics of tacrolimus (Tac) differ among individuals, and genetic polymorphisms of cytochrome P-450 (CYP) 3A4, CYP3A5, and ABCB1 are thought to be involved. The aim of this study was to clarify whether these genetic polymorphisms affect the pharmacokinetics of Tac in patients with ulcerative colitis. METHODS The subjects in this study were 45 patients with moderate-to-severe ulcerative colitis who were resistant to other therapies and were treated with Tac. The subjects were tested for genetic polymorphisms of CYP3A4, CYP3A5, and ABCB1, and the relationship between Tac pharmacokinetics and the remission rate was investigated. RESULTS Of the 45 subjects, 24 (53.3%) were CYP3A5 expressers (Exp), and 21 (46.7%) were non-expressers (Non-Exp). The trough level and the dose-adjusted trough level on days 2-5 were significantly higher in the Non-Exp group than in the Exp group (10.16 ± 5.84 vs 4.47 ± 2.50 ng/mL, P < 0.0001, 139.36 ± 77.43 vs 61.37 ± 41.55 ng/mL per mg/kg/day, P < 0.0001). The percentage of patients achieving the optimal trough level on days 2-5 was significantly higher in the Non-Exp group than in the Exp group (40.0% vs 4.3%, P = 0.01). This trend was also observed on days 7-10. On multivariate analysis, factors associated with achievement of the optimal trough level were food non-intake and Non-Exp of CYP3A5. The remission rate was significantly higher in the Non-Exp group than in the Exp group (47.6% vs 16.7%, P = 0.046). CONCLUSIONS CYP3A5 genetic polymorphisms affected the pharmacokinetics of Tac, so that the short-term clinical remission rate was different between Exp and Non-Exp of CYP3A5.

Abstract
BACKGROUND Oral administration of tacrolimus is an effective remission induction therapy for steroid-refractory/dependent ulcerative colitis (UC). AIM This study aimed to evaluate the short- as well as medium- and long-term effectiveness of tacrolimus therapy. METHODS The medical records of 51 patients treated with tacrolimus for UC at our hospital between July 2009 and December 2011 were reviewed retrospectively. Clinical remission and improvement were defined as a Lichtiger score of 4 or less and as a Lichtiger score of ≤10 and a reduction in the score of ≥3 compared with the baseline score, respectively. Endoscopic findings were evaluated based on the endoscopic activity index and Mayo endoscopic score. RESULTS The clinical effectiveness combining clinical remission and improvement was observed in 62.7% of the patients at 3 months. Thirty-six patients underwent colonoscopy at 3 months, and 12 (33.3%) and 10 patients (27.8%) showed Mayo endoscopic scores of 0 and 1, respectively. On Kaplan-Meier analysis, the overall percentage of event-free survivors, who did not require colectomy nor switching to other induction therapy such as infliximab, was 73.0% at 6 months, 49.9% at 1 year, and 37.8% at 2 years. Patients with a Mayo endoscopic score of 0-1 at 3 months showed significantly better medium- and long-term prognosis than those with a score of 2-3 (p<0.01). All adverse events, including infections in 2 patients, were reversible. CONCLUSIONS Tacrolimus therapy was effective for inducing clinical and endoscopic remission of steroid-refractory/dependent UC. Endoscopic improvement was associated with favorable medium- and long-term prognosis.

Abstract
BACKGROUND The medical management of refractory ulcerative colitis (UC) remains a significant challenge. Two randomised controlled studies have demonstrated tacrolimus therapy is effective for the induction of remission of moderate to severe UC. However, the long term outcomes of UC patients treated with tacrolimus as maintenance therapy are not certain. AIMS This study aims to assess the efficacy of tacrolimus maintenance therapy for refractory UC. METHODS A retrospective review of patients with UC treated with tacrolimus at two London tertiary centres was performed. Clinical outcomes were assessed at six months, at the end of tacrolimus treatment, or at the last follow-up for patients continuing tacrolimus treatment. Modified Truelove-Witts score (mTW) and Mayo endoscopy subscores were calculated. RESULTS 25 patients with UC, treated with oral tacrolimus between 2005 and 2011, were identified. The median duration of tacrolimus treatment was 9 months (IQR 3.7-18.2 months). The median duration of follow-up was 27 months (range 3-66 months). At six months thirteen (52%) patients had achieved and maintained clinical response and eleven (44%) were in clinical remission. The mean mTW score decreased from 10+/-0.5 before therapy, to 5.8+/-0.8 (p≤0.001 95% CI 2.7-5.8) at cessation of treatment or last follow-up. Mayo endoscopy subscore decreased from 2.6+/-0.1 to 1.2+/-0.2 (p≤0.001 mean reduction 1.4, 95% CI 0.8-1.9). Eight patients (32%) subsequently underwent a colectomy within a mean time of 17 months (range 2-45 months). CONCLUSION Tacrolimus is effective for the maintenance of refractory UC and can deliver sustained improvement in mucosal inflammation.

Abstract
Systemic non-biologic agents have long been in clinical use in medicine--often with considerable efficacy, albeit with some adverse effects--as with all medications. With the advent of biologic agents, all of which currently are restricted to systemic use, there is a growing need to ensure which agents have the better therapeutic ratio. The non-biologic agents (NBAs) include a range of agents, most importantly the corticosteroids (steroids). Previous articles by us in this series have discussed systemic use of corticosteroids and purine synthesis inhibitors; the other immunomodulating agents (calcineurin inhibitors, thalidomide, dapsone, colchicine and cyclophosphamide) are reviewed in this final article.

Abstract
Biological functions of antibiotics are not limited to killing. The most likely function of antibiotics in natural microbial ecosystems is signaling. Does this signaling function of antibiotics also extend to the eukaryotic – in particular mammalian – cells? In this review, the host modulating properties of three classes of antibiotics (macrolides, tetracyclines, and β-lactams) will be briefly discussed. Antibiotics can be effective in treatment of a broad spectrum of diseases and pathological conditions other than those of infectious etiology and, in this capacity, may find widespread applications beyond the intended antimicrobial use. This use, however, should not compromise the primary function antibiotics are used for. The biological background for this inter-kingdom signaling is also discussed.

Abstract
BACKGROUND Patients with inflammatory bowel disease who are refractory to standard therapies frequently require surgery. The long-term efficacy of tacrolimus in patients who fail standard immunosuppressive and antitumor necrosis factor α therapy is unknown. METHODS Thirty-five patients (11 Crohn's disease and 24 ulcerative colitis) with medication-resistant disease were treated with oral tacrolimus and reviewed retrospectively. Patients were commenced on tacrolimus 0.1 mg/kg/day, with a trough level targeted between 8 and 12 ng/mL. Clinical response or remission at 30 days, 90 days, and 1 year was assessed. The overall risk of requiring surgery and predictive factors were also assessed. RESULTS All patients had failed a thiopurine, 5 (14%) had also failed methotrexate, while 90% had a primary or secondary nonresponse, or an incomplete response, to an antitumor necrosis factor α agent. The proportions that achieved a clinical response at 30 days, 90 days, and 1 year was 65.7%, 60%, and 31.4%, respectively, whereas the corresponding proportions in remission were 40%, 37.1%, and 22.9%. The cumulative risk of requiring surgery was 40.4% at 1 year and 59.3% at 2 years with a median time to surgery of 22 months (range, 0.5-84 months). Patients who were steroid refractory, or dependent, before starting tacrolimus were more likely to have surgery (P = 0.006), whereas patients who were able to achieve or maintain a clinical response with tacrolimus by 90 days were less likely (P = 0.004). CONCLUSIONS Tacrolimus is able to induce a clinical response in a third and remission in a fifth of medically refractory patients with inflammatory bowel disease at 1 year. A 90-day therapeutic trial is worthwhile in difficult to treat patients.

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
BACKGROUND Several small retrospective studies have reported encouraging response rates in patients with Crohn's disease (CD) treated with tacrolimus. METHODS We conducted a retrospective study of the use of oral tacrolimus for severe CD refractory to anti-tumor necrosis factor agents. Response was defined as a clinician's assessment of improvement after at least 7 days of treatment of one or more of the following: bowel movement frequency, fistula output, rectal bleeding, abdominal pain, extraintestinal manifestations, or well-being. Remission required all of the following: <3 stools per day, no bleeding, abdominal pain or extraintestinal manifestations, and increased well-being. RESULTS Twenty-four eligible patients were treated with tacrolimus for a median of 4 months. Approximately 37% were steroid dependent or steroid refractory. Response and steroid-free remission rates were 67% and 21%, respectively, and lasted for a median of 4 months. Approximately 42% of patients were able to stop steroids and 54% of patients ultimately required surgery within a median of 10 months after starting tacrolimus. Patients with mean tacrolimus trough levels of 10 to 15 ng/mL had the highest rates of response (86%) and remission (57%). Surgery seemed to be postponed in this group compared with others. An adverse event occurred in 75% of patients. Eight of these events (33%) required dose reduction and 6 (25%) led to treatment discontinuation. There were no irreversible side effects or deaths attributable to tacrolimus over a median follow-up of 56 months. CONCLUSIONS Oral tacrolimus seems to be safe and effective in some patients with severe CD refractory to anti-tumor necrosis factor therapy, particularly at a mean trough level of 10 to 15 ng/mL.

Abstract
Background. Tacrolimus (FK506) is effective for patients with ulcerative colitis (UC). However, there are few reports on tacrolimus therapy (TT) with respect to the relationship with endoscopic and clinicopathologic findings. Methods. Thirty patients with moderate/severe active UC refractory to or dependent on corticosteroid were treated with oral tacrolimus. The expression of ectopic MUC5AC in the colon was pathologically analyzed before and at 12 weeks after TT, evaluating the Mayo score and steroid-sparing effects. Results. Both mean disease and endoscopic activity index scores were reduced at levels of statistical significance in 26 UC patients receiving more than one month of TT (P < 0.0001). The dose of prednisolone was reduced by a statistically significant amount (P = 0.00022), and 14 of the 26 patients (53.8%) had steroid-free status 12 weeks after TT. The decrease in ectopic MUC5AC expression in the mucous cells of the colon was significantly associated with endoscopic improvement of inflammation in the UC patients with TT (P = 0.043). Loss of ectopic MUC5AC expression was detected in all patients who had complete response. Conclusions. Tacrolimus appears to be effective for the treatment of moderate/severe UC patients. Loss of ectopic MUC5AC expression may be important for pathologic remission in the colon of UC patients.

Abstract
Endothelial and epithelial cells form selectively permeable barriers that separate tissue compartments. These cells coordinate movement between the lumen and tissue via the transcellular and paracellular pathways. The primary determinant of paracellular permeability is the tight junction, which forms an apical belt-like structure around endothelial and epithelial cells. This chapter discusses endothelial and epithelial barriers in graft-versus-host disease after allogeneic bone marrow transplantation, with a focus on the tight junction and its role in regulating paracellular permeability. Recent studies suggest that in graft-versus-host disease, pathological increases in paracellular permeability, or barrier dysfunction, are initiated by pretransplant conditioning and sustained by alloreactive cells and the proinflammatory milieu. The intestinal epithelium is a significant focus, as it is a target organ of graft-versus-host disease, and the mechanisms of barrier regulation in intestinal epithelium have been well characterized. Finally, we propose a model that incorporates endothelial and epithelial barrier dysfunction in graft-versus-host disease and discuss modulating barrier properties as a therapeutic approach.

Abstract
BACKGROUND Steroid-refractory ulcerative colitis (UC) remains a challenging condition warranting surgery upon failure of pharmacological treatment. Calcineurin inhibitors or infliximab are alternatives in this situation. Data on the efficacy and safety of tacrolimus in this setting are limited. AIM To study the short-term efficacy and safety of tacrolimus in moderate-to-severe steroid-refractory UC. The role of thiopurines in this situation and predictors of colectomy were evaluated. METHODS In three centers, all charts from tacrolimus-treated patients with steroid-refractory UC were reviewed. Efficacy was assessed by colectomy-free survival and clinical remission at 3 months. RESULTS We identified 130 patients with pancolitis in 75 (59%), left-sided disease in 35 (27%) and proctitis in 18 patients (14%) (disease localisation not obtainable in two patients). The median age was 40 (range: 18-81). Clinical activity according to the median Lichtiger score decreased from 13 (range: 4-17) at baseline to 3 (0-14) at week 12. Eighteen patients underwent colectomy within the first 3 months of treatment with tacrolimus (14%). Clinical remission was achieved in 94 patients (72%) in this period. Thiopurines given in parallel to tacrolimus tended to limit colectomy and significantly increased remission (P = 0.002) in the short-term. No other predictors of colectomy or remission were identified. Side effects were noticed in 53% of patients and no severe events occurred. CONCLUSION This large survey confirms the efficacy and safety of tacrolimus in patients with steroid-refractory ulcerative colitis.

Abstract
BACKGROUND Calcineurin inhibitors (CNIs) such as cyclosporine and tacrolimus have been shown to be effective for treatment of patients with steroid-dependent or steroid-refractory ulcerative colitis (UC) with moderate to severe activity. However, it has not been determined whether readministration of CNIs is effective in patients who experience relapse after remission induced by CNIs. OBJECTIVE To determine the effect of readministration of CNIs in patients who had initially responded to CNIs. METHODS A review of the medical records of 46 patients with moderate to severe UC who were treated with a CNI at a single tertiary teaching hospital with 840 beds was conducted. Remission was defined as a clinical activity index (CAI) score of 3 or less within 2 months of starting CNI therapy. Response was defined as a CAI score of 4 or higher but had decreased by half from the start of CNI therapy. Relapse was defined as flare-up of symptoms that required an additional treatment or colectomy. RESULTS Of the 46 patients, 37 (80%) achieved clinical remission or response with the initial CNI treatment. Among those 37 patients, 19 experienced relapse (median duration to relapse, 6.4 months), 12 of whom were readministered a CNI. Of the 12 patients, 2 achieved clinical remission, 2 had a response, and the remaining 8 had no response to the CNI. In addition, all patients who responded to CNI readministration experienced relapse within 6 months. CNI readministration was significantly less effective than the initial administration for treatment of UC (80% vs 33%; p = 0.0014). CONCLUSIONS Readministration of CNIs for relapse after remission with CNI treatment does not seem to be successful. Alternative therapies such as anti-tumor necrosis factor antibody should be used or colectomy should be considered.

Abstract
Diabetic retinopathy is a complex disease that has potential involvement of inflammatory in its pathogenesis. We hypothesized that tacrolimus (FK506), one of the potent immunosuppressive agent, could be effective against diabetic retinopathy, which involves significant inflammation. The aim of the present study was to investigate the effects of FK506 in early retinal changes of streptozotocin-induced diabetic mice. The effect of FK506 treatment (10 μg per eye for one week) was evaluated by TNF-a, VEGF, iNOS and COX-2 protein levels measurement, neovascularization, and the activation of NF-kB in the retina. Increased amounts of cytokines, neovascularization, inflammatory markers and activation of NF-kB were observed in retina from diabetic mice. FK506 treatment significantly lowered retinal TNF-a, VEGF, iNOS and COX-2. Further, treatment with FK506 significantly suppressed diabetes-related neovascularization, as well as the activation of NF-kB. These data demonstrated that FK506 attenuates the degree of retinal inflammation and preserving the neovascularization in early diabetic mice.

Abstract
BACKGROUND We report a multicenter study of oral tacrolimus (FK506) therapy in steroid-refractory ulcerative colitis (UC). METHODS In a placebo-controlled, double-blind study, 62 patients with steroid-refractory, moderate-to-severe UC were randomized into either a tacrolimus group or a placebo for 2 weeks. Patients were evaluated using the Disease Activity Index (DAI). As an entry criterion, patients had to have a total DAI score of 6 or more as well as a mucosal appearance subscore of 2 or 3. Clinical response was defined as improvement in all DAI subscores. Mucosal healing was defined as mucosal appearance subscore of 0 or 1. Clinical remission was defined as a total DAI score ≤ 2 with an individual subscore of 0 or 1. RESULTS The mean total DAI score at study entry was 9.8 ± 1.61 in the tacrolimus group and 9.1 ± 1.05 in the placebo group. At week 2 the clinical response rate was 50.0% (16/32) in the tacrolimus group and 13.3% (4/30) in the placebo group (P = 0.003). The rate of mucosal healing observed was 43.8% (14/32) in the tacrolimus group and 13.3% (4/30) in the placebo group (P = 0.012) and the rate of clinical remission observed was 9.4% (3/32) in the tacrolimus group and 0.0% (0/30) in the placebo group (P = 0.238). The therapies in this study were well tolerated, with only minor side effects. CONCLUSIONS Oral tacrolimus therapy in patients with steroid-refractory UC shortened the acute phase and induced rapid mucosal healing. These results suggest that tacrolimus therapy is useful as an alternative therapy for steroid-refractory UC.

Abstract
BACKGROUND Several published studies have evaluated the efficacy of tacrolimus in the management of Crohn's disease with variable conclusions. AIM To review systematically the evidence examining the efficacy and safety of tacrolimus in treating Crohn's disease. METHODS The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (PUBMED) and EMBASE (1984 to January 2011) were searched. Also, references from selected articles were examined. Case series (five or more patients), cohort and randomised controlled trials were eligible for inclusion, incorporating oral, intravenous or topical tacrolimus therapy. The primary outcome was induction of remission of active Crohn's disease. RESULTS Eleven studies met the inclusion criteria which included 163 patients, of which 127 received tacrolimus therapy. In patients with luminal Crohn's disease, the crude pooled remission rate for tacrolimus was 44.3% (range, 7-69%) and the crude pooled response rate was 37.1% (range, 14-57%). For patients with perianal disease using systemic tacrolimus, crude pooled remission rate was 28.6% (range, 0-64%) and crude pooled response rate was 38.8% (range, 0-57%). Combining data from two studies using topical tacrolimus, 35.7% of patients achieved remission and 28.6% partial response. Nonserious adverse effects are common, particularly tremor, paraesthesia and headache. Reversible nephrotoxity occurred in 16% of patients. CONCLUSIONS The current evidence; although of a poor quality, appears to support the use of tacrolimus in Crohn's disease. High quality randomised controlled trials are needed.

Abstract
OBJECTIVE To perform a survey of thiopurine treatment in inflammatory bowel disease (IBD) among Swedish gastroenterologists. MATERIAL AND METHODS A web-based questionnaire consisting of 25 multiple-choice questions was sent to 322 gastroenterologists in adult practice. RESULTS A total of 132 questionnaires were received giving a response rate of 41%. Thiopurines were used by all 122 gastroenterologists in IBD practice and azathioprine was the first-choice thiopurine among 118 (97%) of them. Almost all gastroenterologists (97%) used weight-based dosing that was gradually escalated. The vast majority (89%) considered that efficacy should be evaluated within 6 months of therapy, while opinions regarding the optimal duration of therapy varied considerably. It was seen that 74% switched thiopurine in case of intolerance to the first-line substance. Thiopurine S-methyltransferase (TPMT) determinations were performed by 74% of the gastroenterologists and 67% used metabolite measurements. TPMT analyzers were more likely to measure metabolites (74 vs. 43%, p = 0.002). A quarter of the respondents were familiar with unconventional immunomodulation (co-administration of allopurinol, 6-thioguanine, mycophenolate mofetil or tacrolimus) and these respondents were also more likely to measure metabolites (79 vs. 52%; p = 0.002). CONCLUSIONS Thiopurines are well established in the treatment of IBD among Swedish gastroenterologists. New and evolving knowledge about thiopurine therapy in IBD has been adapted to a large extent. Whether this change in clinical practice will have an impact on treatment outcomes has yet to be proven.

Abstract
Ulcerative colitis (UC) is a chronic disease featuring recurrent inflammation of the colonic mucosa. The goal of medical treatment is to rapidly induce a steroid-free remission while at the same time preventing complications of the disease itself and its treatment. The choice of treatment depends on severity, localization and the course of the disease. For proctitis, topical therapy with 5-aminosalicylic acid (5-ASA) compounds is used. More extensive or severe disease should be treated with oral and local 5-ASA compounds and corticosteroids to induce remission. Patients who do not respond to this treatment require hospitalization. Intravenous steroids or, when refractory, calcineurin inhibitors (cyclosporine, tacrolimus), tumor necrosis factor-α antibodies (infliximab) or immunomodulators (azathioprine, 6-mercaptopurine) are then called for. Indications for emergency surgery include refractory toxic megacolon, perforation, and continuous severe colorectal bleeding. Close collaboration between gastroenterologist and surgeon is mandatory in order not to delay surgical therapy when needed. This article is intended to give a general, practice-orientated overview of the key issues in ulcerative colitis treatment. Recommendations are based on published consensus guidelines derived from national and international guidelines on the treatment of ulcerative colitis.

Abstract
AIMS Hepatocyte growth factor (HGF) modulates intestinal epithelial cell proliferation and migration. We previously reported that systemic administration of recombinant human HGF (rh-HGF) ameliorated experimental colitis. However, an increase in serum HGF concentrations may induce undesired systemic effects, limiting the use of rh-HGF. To avoid possible side effects, we investigated the safety and efficacy of rectally administered rh-HGF as a treatment for experimental colitis. MAIN METHODS We measured serum human HGF concentration following a single rectal enema of rh-HGF. Rats with 2,4,6-trinitrobenzene sulfonic acid (TNBS)- or dextran sulfate sodium (DSS)-induced colitis were treated with rectal enemas of rh-HGF once a day for seven days. The degree of mucosal injuries and the proliferative activity of the colon epithelium were examined. KEY FINDINGS Rats administered a rectal enema of rh-HGF at a dose of 0.1 mg/ml or less had no detectable rh-HGF in the serum. Repeated enemas of rh-HGF at this dose significantly reduced mucosal injuries, both with respect to lesion size and inflammatory cell infiltration. This regimen also stimulated proliferation of epithelial cells surrounding injured mucosa; however, the cell proliferation of uninjured mucosa was not affected by this local treatment. SIGNIFICANCE Rectally administered rh-HGF selectively accelerates the repair of injured mucosa in rat experimental colitis without systemic exposure to HGF. Rectal enemas of HGF are thus a potential novel and safe therapy for IBD.

Abstract
Conservative management of inflammatory bowel disease (IBD) is based on a combination of drugs, including aminosalicylates (ASAs), steroids, antibiotics, immunosuppressives and biologic agents. Although various side effects have been related to treatment regimens, drug-induced nephrotoxicity is rather uncommon. Furthermore, it is often underestimated since renal function deterioration may be attributed to the underlying disease. The nephrotoxicity of ASAs and cyclosporine A seems well established, but recent data have suggested a possible role of biologic agents such as infliximab and adalimubab in renal impairment. The aim of this review is to summarize the nephrotoxic effects of medical treatment as well as to express possible caveats in the administration of novel agents in IBD.

Abstract
Renal manifestations and complications are not rare in patients with inflammatory bowel disease (IBD) and may present as nephrolithiasis, amyloidosis, tubulointerstitial nephritis, and glomerulonephritis. Symptoms of renal impairment are not always specific and since the underlying bowel disease is preponderant, renal function deterioration may be underestimated. Additionally, medical treatment of patients with IBD such as aminosalicylates, cyclosporine, and tumor necrosis factor-α inhibitors can cause renal complications, although direct correlation to bowel disease is not always clear. The well-documented renal manifestations and complications of IBD, as well as the possible renal side effects of new drugs, emphasize the need for periodic evaluation of renal function. New markers of renal function may facilitate early diagnosis and unravel the complex mechanisms responsible for kidney damage. The purpose of this review is to summarize the renal manifestations and complications as well as the markers of renal function utilized in IBD, attempting to shed more light on the pathophysiology of renal damage in IBD.

Abstract
Tacrolimus (Tac) is effective in the treatment of steroid-refractory ulcerative colitis (UC); however, nonresponse and unpredictable side effects are major limitations. Because Tac response in patients who have undergone solid-organ transplantation has been associated with the presence of variants in CYP3A and ABCB1, we elucidated the contributions of CYP3A4*1B and CYP3A5*3 and of ABCB1 1236C>T, 2677G>T,A, and 3435C>T polymorphisms to Tac response in 89 patients with UC. Short-term remission and response were achieved in 61 and 14% of the patients, respectively, and were associated with colectomy-free survival. In a linear logistic regression model, patients with homozygous variants for one of the three ABCB1 alleles showed significantly higher short-term remission rates as compared with those of other genotypes. The effects held true after multivariate analysis including multiple comparisons and were more pronounced after correction for dose-adjusted Tac blood trough levels. We suggest that ABCB1, but not CYP3A5, may predict short-term remission of Tac in steroid-refractory UC.

Abstract
BACKGROUND Intravenous cyclosporine A (CsA) is an effective treatment for patients with severe, steroid-refractory ulcerative colitis (UC). Like the response to CsA, clinical trials have shown that two-thirds of patients with refractory UC respond to tacrolimus therapy. However, it is unclear how/when this agent should be used for patients with active UC. METHODS We reviewed the results of previous studies regarding calcineurin inhibitors in UC patients. We examined the best way to use tacrolimus to obtain maximum efficacy by comparing the results from clinical trials with those from a recent survey in Japan. RESULTS Calcineurin inhibitors are useful to induce remission in patients with refractory UC; however, the long-term prognosis has not been shown to be improved by CsA. Early intervention with CsA/tacrolimus may improve the long-term prognosis of UC patients just as infliximab does for Crohn's disease patients. Recent studies have indicated that a fasting state and administration of a higher dosage of tacrolimus at the beginning of therapy are critical in ensuring that the target trough concentration of the agent is reached. CONCLUSIONS The use of higher initial doses of tacrolimus ensured that patients achieved their target levels. Further studies will be needed to elucidate the efficacy of top-down therapy with tacrolimus in patients with UC. Physicians must know how to use calcineurin inhibitors to obtain maximum efficacy.

Abstract
BACKGROUND Up to one-third of patients with inflammatory bowel disease (IBD) do not respond to, or are intolerant of conventional immunosuppressive drugs. Although biological agents are alternative treatments, they may not be suitable or available to some patients. AIM To review the evidence for use of nonbiological drugs in the treatment of patients with IBD refractory to corticosteroids or thiopurines. METHODS A literature search was performed using PubMed for English language publications with predetermined search criteria to identify relevant studies. RESULTS Published evidence from uncontrolled series and controlled clinical trials has been used to produce a practical approach relevant to clinical practice which incorporates the indication, optimal dose, and side effects of various therapies including tacrolimus, methotrexate, thalidomide, tioguanine, mycophenolate mofotil, leucocyte apheresis, nutritional therapy, antibiotics, probiotics, allopurinol, rectal acetarsol and ciclosporin in the treatment of patients with refractory ulcerative colitis and Crohn's disease. Approaches to optimise thiopurine efficacy are also discussed. CONCLUSIONS Patients with IBD refractory to corticosteroids or thiopurines may respond to alternative anti-inflammatory chemical molecules, but the evidence base for many of these alternatives is limited and further trials are needed.

Abstract
Rectally administered topical agents have demonstrated efficacy in the maintenance of distal colitis (DC) and proctitis and as they are rarely associated with significant blood drug levels, side effects are infrequent. The topical 5-aminosalicylic acid (5-ASA) suppositories and enemas target different regions of the distal colon and are effective for proctitis and DC, respectively. They demonstrate clinical results that are better than oral 5-ASAs and are preferred to topical steroids with better clinical, endoscopic and histological outcomes, without the risk of adrenal suppression. Disease resistant to topical agents, however, can be extremely difficult to manage. The addition of oral 5ASAs, steroids, immunosuppressants and the anti-tumor necrosis factor-α agents may be effective, but can result in significant side effects and not all patients will respond to the therapies. It is for these patients that new and novel therapies are required. Novel topical agents have been proposed for the management of resistant DC. These agents included butyrate, cyclosporine, and nicotine enemas, as well as tacrolimus suppositories, and tacrolimus, ecabet sodium, arsenic, lidocaine, bismuth, rebamipide and thromboxane enemas. While some of these agents appear to demonstrate impressive outcomes, the majority have only been examined in small open-labeled studies. There is thus a desperate need for more randomized double-blinded placebo controlled studies to investigate the clinical utility of these topical therapies. This review summarizes the efficacy of the established topical therapies, and explores the available data on the new and novel topical agents for the management of DC and proctitis.

Abstract
BACKGROUND Children with severe corticosteroid-resistant ulcerative colitis either need to undergo surgery or be treated with more intensive immunosuppression. Our aim was to characterize the short- and long-term outcomes and adverse events associated with the use of tacrolimus in a steroid-refractory pediatric population. METHODS We retrospectively reviewed the medical records of 46 children with steroid-refractory colitis treated with tacrolimus at Children's Hospital Boston between 1994 and 2008. Oral tacrolimus was initiated at a dose of 0.1 mg/kg twice a day and titrated to yield trough levels of 10-15 ng/mL for induction, and 5-10 ng/mL once in remission. The Pediatric Ulcerative Colitis Activity Index (PUCAI) and other measures of disease activity, adverse events, and long-term outcomes were assessed. Statistical analysis of outcomes was performed using SAS statistical software. RESULTS Ninety-three percent of patients were discharged without undergoing surgery. The median length of stay after starting tacrolimus was 10 days (range 4-37 days). The mean PUCAI score was 68 ± 13 prior to initiating tacrolimus, and 27 ± 18 at the time of hospital discharge. The probability of avoiding colectomy after starting tacrolimus was 40% at 26 months. The most common adverse events included hypertension (52%) and tremor (44%). There was one seizure and no deaths. CONCLUSIONS Tacrolimus is useful as induction therapy in pediatric patients with corticosteroid-refractory colitis and side effects are generally mild and reversible. Despite these findings, many patients develop exacerbations of colitis upon transition to maintenance therapies. The long-term colectomy rate in this challenging population remains ≈60% over time.

Abstract
BACKGROUND Tacrolimus is a novel immunomodulator for inflammatory bowel diseases. Immunosuppressive effects of tacrolimus on T cells are well known; however, the effects of tacrolimus on macrophages remain unclear. The aim of this study was to investigate the effects of tacrolimus on activated macrophages and to examine its efficacy in murine colitis models. METHODS Proinflammatory cytokine production from lipopolysaccharide (LPS)-stimulated peritoneal macrophages of IL-10-knockout (KO) mice with and without tacrolimus was measured. We investigated the effects of tacrolimus on nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), and caspase activation in macrophages and the induction of apoptosis in macrophages in vitro and examined the in vivo apoptotic effect of tacrolimus on colonic macrophages in IL-10-KO mice. We evaluated the effect of the rectal administration of tacrolimus on colonic inflammation in IL-10-KO mice and dextran sulfate sodium (DSS)-induced colitis in CB.17/SCID mice. RESULTS Proinflammatory cytokine production from tacrolimus-treated macrophages was significantly lower than that from untreated cells. Tacrolimus suppressed LPS-induced activation of both NF-κB and MAPK in macrophages and induced apoptosis of macrophages via activation of caspases 3 and 9. Rectal administration of tacrolimus evoked apoptosis of colonic macrophages in IL-10-KO mice. Moreover, the rectal administration of tacrolimus ameliorated colitis in IL-10-KO mice and DSS-induced colitis in CB.17/SCID mice. Gene expression of inflammatory cytokines in colonic mucosa was significantly lower in tacrolimus-treated mice than in untreated mice. CONCLUSIONS Tacrolimus suppresses the function of activated macrophages and promotes their apoptosis, which may lead to the amelioration of colonic inflammation.

Abstract
Distal colitis (DC) can be effectively treated with topical 5ASA agents. Suppositories target the rectum while enemas can reliably reach the splenic flexure. Used in combination with oral 5ASAs, the control of the inflammation is even more effective. Unfortunately, resistant DC does occur and can be extremely challenging to manage. In these patients, the use of steroids, immunosuppressants and the anti-tumor necrosis factor α agents are often required. These, however, can be associated with systemic side effects and are not always effective. The investigation of new topical therapeutic agents is thus required as they are rarely associated with significant blood drug levels and side effects are infrequent. Some of the agents that have been proposed for use in resistant distal colitis include butyrate, cyclosporine and nicotine enemas as well as tacrolimus suppositories and tacrolimus, ecabet sodium, arsenic, lidocaine, rebamipide and Ridogrel® enemas. Some of these agents have demonstrated impressive results but the majority of the agents have only been assessed in small open-labelled patient cohorts. Further work is thus required with the investigation of promising agents in the context of randomized double-blinded placebo controlled trials. This review aims to highlight those potentially effective therapies in the management of resistant distal colitis and to promote interest in furthering their investigation.
