Abstract
BACKGROUND AND AIMS To date, no large-scale studies have evaluated long-term outcomes of infliximab (IFX) treatment in Korean patients with Crohn's disease (CD). METHODS We analyzed long-term clinical responses to IFX in 582 Korean CD patients who received scheduled IFX treatments at Asan Medical Center. Clinical responses were defined as maintaining IFX without major abdominal surgery (MAS) or dose intensification. RESULTS Between February 2002 and July 2015, a total of 11,990 IFX infusions were administered to 582 Korean patients with CD over a median period of 36 months. At the end of follow-up, 316 (54.3 %) were still receiving IFX without MAS (71 patients, 12.2 %) or dose intensification (86 patients, 14.8 %). IFX was stopped in 109 (18.7 %) patients because of a loss of response (48 patients, 8.2 %), adverse events (30 patients, 5.2 %), or patient preferences or problems with reimbursement (31 patients, 5.3 %). The cumulative survival for maintenance of IFX without MAS or dose intensification was 89.0, 75.9, 68.3, and 50.8 % at 1, 2, 3, and 5 years, respectively. Multivariate regression analysis identified older age at the initiation of IFX (≥40 years, P = 0.006) and a longer disease duration (≥3 years, P = 0.020) as independent positive predictors of a poorer response to IFX. CONCLUSIONS The long-term efficacy of IFX in a large, real-life cohort of Korean patients with CD appears to be similar to that in previously published Western studies. Our findings support the early use of IFX to obtain better clinical outcomes.

Abstract
BACKGROUND Infliximab is licenced for use in Crohn's disease (CD). Trial data demonstrate that infliximab is effective for inducing remission of active CD, healing fistulising CD, and preventing relapse once in remission. However, long-term data regarding efficacy, safety, and predictors of response are still emerging. AIM To examine these issues in a large cohort of patients who received infliximab for CD. METHODS A retrospective analysis of prospectively collected data was performed for 210 patients receiving infliximab for luminal or fistulising CD. Response to infliximab induction therapy, and sustained clinical benefit, were assessed by a decrease in Harvey-Bradshaw Index (HBI) of ≥ 2 points. Remission was defined as an HBI ≤ 4. Physician's global assessment was used where HBI could not be obtained. Demographic and disease factors that may predict response to therapy were analysed by Kaplan-Meier plots and univariate and multivariate analyses. RESULTS Overall, 173 (82.4%) patients responded to infliximab induction, with 114 (65.9%) achieving sustained clinical benefit. Almost 40% of the study cohort had an HBI ≤ 4, indicating remission, at last point of follow-up (median 24 months). Concomitant immunosuppression predicted sustained clinical benefit in the first 6 months of therapy (P=0.03). An inflammatory disease phenotype (P=0.04 univariate analysis, P=0.03 Kaplan Meier analysis) and male gender (P=0.03) also predicted sustained clinical benefit. Episodic therapy was associated with an increased likelihood of secondary non-response. Adverse events, including malignancies, were few. CONCLUSION In this single centre study, infliximab was efficacious and well-tolerated in CD.

Abstract
Anti-tumor necrosis factor (TNF) therapy to treat inflammatory bowel disease has been available for more than a decade. Although extensive data on the outcome of anti-TNF therapy from individual clinical trials and patient cohorts are available, integrated guidance on the best use of such therapy to achieve optimal clinical outcomes when managing patients with luminal Crohn's disease is lacking. This review combines published data to establish practical strategies for anti-TNF therapy with respect to effective and safe timing of introduction, use of concurrent immunosuppressive therapy, dose escalation, managing relapse, changing drugs, pregnancy and breast feeding, and stopping drug treatment.

Abstract
The advent of biological therapy has revolutionized inflammatory bowel disease (IBD) care. Nonetheless, not all patients require biological therapy. Selection of patients depends on clinical characteristics, previous response to other medical therapy, and comorbid conditions. Availability, reimbursement guidelines, and patient preferences guide the choice of first-line biological therapy for luminal Crohn's disease (CD). Infliximab (IFX) has the most extensive clinical trial data, but other biological agents (adalimumab (ADA), certolizumab pegol (CZP), and natalizumab (NAT)) appear to have similar benefits in CD. Steroid-refractory, steroid-dependent, or complex fistulizing CD are indications for starting biological therapy, after surgical drainage of any sepsis. For fistulizing CD, the efficacy of IFX for inducing fistula closure is best documented. Unique risks of NAT account for its labeling as a second-line biological agent in some countries. Patients who respond to induction therapy benefit from systematic re-treatment. The combination of IFX with azathioprine is better than monotherapy for induction of remission and mucosal healing up to 1 year in patients who are naïve to both agents. Whether this applies to other agents remains unknown. IFX is also effective for treatment-refractory, moderate, or severely active ulcerative colitis. Patients who have a diminished or loss of response to anti-tumor necrosis factor (TNF) therapy may respond to dose adjustment of the same agent or switching to another agent. Careful consideration should be given to the reasons for loss of response. There are insufficient data to make recommendations on when to stop anti-TNF therapy. Preliminary evidence suggests that a substantial proportion of patients in clinical remission for >1 year, without signs of active inflammation can remain in remission after stopping treatment.

Abstract
BACKGROUND Infliximab has shown benefit in Crohn's disease (CD) and ulcerative colitis (UC). OBJECTIVE Evaluation of long-term outcome of therapy for both diseases. METHODS We analyzed retrospectively patients treated at infusion centers from one institution. Demographic, laboratory parameters leading up to biologic therapy and the subsequent pattern of outcomes in either disease were established as a database. Initial failure, subsequent need to change therapy, or need to adjust therapy were evaluated. Kruskal-Wallis (nonparametric) tests to compare two groups and Kaplan-Meier survival curve analysis were used to compare outcomes. RESULTS Over approximately 6 years, 71 CD and 26 UC patients received 999 and 215 infusions, respectively, for a median of 62 months. Of these, 17% for CD and 19% for UC patients were primary failures. Following the start of infliximab, 18% of CD and 11% of UC patients required stoppage and switching to another type of therapy. In either CD or UC patients, 54% or 62%, respectively, continued therapy without the need to change to other treatments. Few serious side effects were noted. No important statistically significant differences in treatment patterns or outcome were observed between the groups. DISCUSSION Long-term treatment of both inflammatory bowel diseases reflects outcomes of clinical trials. CONCLUSIONS This study emphasizes similarities between CD and UC and reports therapeutic success for an extended time.

Abstract
Infliximab (IFX) has tremendously enriched the therapy of inflammatory bowel diseases (IBD) and other immune mediated diseases. Although the efficacy of IFX was undoubtedly proven during the last decade numerous publications have also caused various safety concerns. To summarize the immense information concerning adverse events and safety issues the Austrian Society of Gastroenterology and Hepatology launched this evidence based consensus on the safe use of IFX which covers the following topics: infusion reactions and immunogenicity, skin reactions, opportunistic infections (including tuberculosis), non-opportunistic infections (bacterial and viral), vaccination, neurological complications, hepatotoxicity, congestive heart failure, haematological side effects, intestinal strictures, stenosis and bowel obstruction (SSO), concomitant medication, malignancy and lymphoma, IFX in the elderly and the young, mortality, fertility, pregnancy and breast feeding. To make the vast amount of information practicable for routine application the consensus was finally condensed into a checklist for a safe use of IFX which consists of two parts: issues to be addressed prior to anti-TNF therapy and issues to be addressed during maintenance. Both parts are further divided into obligatory and facultative items.

Abstract
BACKGROUND The increasing awareness of increased risk for opportunistic infections when combining several immunosuppressant drugs led to new treatment goals for inflammatory bowel disease including limited use of steroids. AIM To conduct a systematic review to establish figures for steroid withdrawal in anti-TNF treated inflammatory bowel disease-patients. METHODS Medline was searched using the search-terms Ulcerative Colitis (UC) [Mesh], Crohn Disease (CD) [Mesh], IBD [Mesh], crohn, colitis, IBD and steroid sparing, all combined with infliximab and adalimumab. We selected English-language publications that addressed the effect of anti-TNF on steroid withdrawal. Studies had to assess patients with luminal CD or UC. Numbers of patients who were able to withdraw steroids were calculated. RESULTS Six studies could be included; five reporting on infliximab and one on adalimumab. Studies were heterogeneously designed. Overall, in the adult population, up to 38% of the patients were able to withdraw corticosteroids during infliximab therapy. In the paediatric population, up to 75% of the patients were able to withdraw corticosteroids during infliximab therapy. CONCLUSIONS Although a consensus on the definition of steroid-sparing is lacking, approximately two-thirds of the inflammatory bowel disease-patients are unable to withdraw corticosteroid treatment during anti-TNF therapy.

Abstract
BACKGROUND In the randomized, double-blind, placebo-controlled CHARM trial, adalimumab was more effective than placebo in maintaining clinical remission for patients with moderate-to-severe Crohn's disease (CD) through 56 weeks. AIM To substantiate the long-term safety and clinical benefits of adalimumab through 2 years of therapy in CHARM and its open-label extension (ADHERE). METHODS Patients entering ADHERE on blinded therapy received adalimumab 40 mg every other week (eow). Patients who had already moved to open-label adalimumab eow or weekly in CHARM continued their regimens. Data were analysed by originally randomized treatment group at CHARM baseline (adalimumab 40 mg eow, adalimumab 40 mg weekly, or placebo), regardless of whether patients entered ADHERE or received open-label adalimumab (eow or weekly). RESULTS After up to 2 years of therapy, 37.6%, 41.9% and 49.8% of patients originally randomized to placebo, adalimumab eow and adalimumab weekly, respectively, were in clinical remission. All groups experienced sustained improvements on the Inflammatory Bowel Disease Questionnaire. Decreasing hazard rates for both all-cause and CD-related hospitalizations were observed over time. Over a 2-year period, the rates of serious adverse events and malignancies (33.3 and 1.1 events/100-patient-years respectively) were similar to those observed during the overall adalimumab CD clinical development programme. CONCLUSIONS Adalimumab demonstrated sustained maintenance of clinical remission, improvements in quality of life and reductions in hospitalization during long-term treatment for CD, with no new safety concerns identified.

Abstract
INTRODUCTION Infliximab was launched for the treatment of Crohn's disease (CD) in 1999. We set up a follow-up protocol to meticulously study disease development with repeated infusions of infliximab. AIM To follow the effects of infliximab treatment on disease activity, blood chemistry, quality of life, plasma nitrite, and titers of Saccharomyces cerevisiae antibodies (ASCA). METHODS During 1999-2008, CD patients were monitored for disease activity by Harvey-Bradshaw index, blood chemistry with hemoglobin, albumin, C-reactive protein, platelet count, leukocyte count and creatinine, quality of life by the Short Health Scale, and plasma nitrite. During the first year of treatment, follow-up was done repeatedly before and 1 week after each infusion and thereafter every year before the last infusion for 5 years. ASCA was analyzed by flow cytometry with fluorescein isothiocyanate-labelled antibodies. RESULTS A total of 1061 infusions were given to 103 patients; 92 responders and 11 nonresponders. Responders were further monitored and Harvey-Bradshaw index decreased with infusions during the first year of treatment (P < 0.0001), whereas hemoglobin (P < 0.01) and albumin (P <0.001) increased, C-reactive protein (P < 0.01) decreased, platelets (P <0.001) increased, and leukocytes (P< 0.01) decreased. Creatinine was not affected. Short Health Scale (questions analyzed separately) decreased (P < 0.0001), and nitrite (P < 0.001) increased. During the next 4 years the improved values remained stable. Adverse effects were noted among 32% of the patients; local circulatory reactions being most common. No correlation between ASCA titers and inflammatory activity or infliximab treatment was found. CONCLUSION Infliximab treatment is highly effective in responders and maintains symptomatic improvement and low inflammatory activity over years in CD patients.

Abstract
PURPOSE Infliximab may represent an adjuvant to surgical therapy in patients with severe anal Crohn's disease as it has been shown to affect rapid remissions in a proportion of cases. PATIENTS AND METHODS Nineteen patients underwent infliximab therapy 5 mg/kg perioperatively to scheduled anal reconstructive surgery for complicated fistulising anal Crohn's disease. RESULTS One adverse event was recorded (generalised exanthema with subsequent resolution). Eight patients showed complete clinical remission refusing further surgery. One of the eight relapsed during follow-up and was continued on infliximab. Surgery consisted of advancement flaps. It was successful at first attempt in nine of the remaining 11 patients (82%). Operative fistula closure remained unsuccessful in two patients. Overall, 16 of 19 patients (84%) with advanced anal Crohn's disease had a favourable outcome. CONCLUSION The use of infliximab as adjuvant to surgery in this series of patients with complicated anal Crohn's disease was safe. Although the data is uncontrolled a positive effect of infliximab on the outcome of surgery may be postulated since our results compare favourably with other studies.

Abstract
CD137 is a member of the tumor necrosis factor receptor family, and is involved in the regulation of activation, proliferation, differentiation and apoptosis of T cells, B cells, monocytes, dendritic cells, natural killer cells and granulocytes. Here report that soluble forms of murine CD137 (sCD137) are generated by differential splicing and are released by activated T cells. Levels of sCD137 correlate with cell activation and the extent of cell death but not with cellular proliferation. While CD8+ T cells express significantly more cell surface CD137 than CD4+ T cells, both T cell subsets express similar levels of sCD137, resulting a twofold increased ratio of soluble to cell surface CD137 for CD4+ T cells. sCD137 exists as a trimer and a higher order multimer, can bind to CD137 ligand, and inhibits secretion of IL-10 and IL-12. sCD137 is present in sera of mice with autoimmune disease but is undetectable in sera of healthy mice.
