Abstract
Inflammatory bowel diseases, which include Crohn's disease and ulcerative colitis, are lifetime chronic and progressive disorders of poorly known etiology. Over the past few decades, new therapeutic approaches, including early and more aggressive intervention with immunomodulators and biological agents have offered the possibility of a favorable modification in the natural history of inflammatory bowel diseases. Area covered: Here, we review the literature about the effectiveness of early detection and intervention in adult inflammatory bowel diseases patients. Expert commentary: Detecting and managing early stages of inflammatory bowel diseases represents an effective strategy to avoid disease progression in selected patients. Primary care physicians may play a key role in attaining these outcomes by recognizing the signs and symptoms early and making timely referrals. Moreover, early therapeutic intervention with complete disease control may allow dose reduction or even treatment withdrawal in the maintenance phase, reducing side effects, costs, and also improving quality of life.

Long-term outcome of pediatric-onset Crohn's disease: A population-based cohort study. Dig Liver Dis 2019; 51:496-502. [PMID: 30611597 DOI: 10.1016/j.dld.2018.11.033] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Revised: 11/23/2018] [Accepted: 11/26/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Pediatric-onset Crohn's disease (CD) may represent a more severe form of disease. The aim of this study was to describe long-term outcome and identify associated risk factors of complicated behavior in a large population-based pediatric-onset CD cohort. PATIENTS AND METHODS Cases included all patients recorded in the EPIMAD registry diagnosed with definite or probable CD between January 1988 and December 2004, under the age of 17 years at the time of diagnosis, with at least two years of follow-up. RESULTS Five hundred and thirty-five patients were included. Median follow-up was 11.1 years [IQR, 7.3-15.0]. At the end of follow-up, 8% (n = 44) of patients had pure ileal disease (L1), 8% (n = 44) had pure colonic disease (L2), and 83% (n = 439) had ileocolonic disease (L3). L4 disease and perianal disease were observed in 42% (n = 227) and 16% (n = 85) of patients, respectively. At the end of follow-up, 58% (n = 308) of patients presented complicated disease behavior (B2, 39% and B3, 19%), and 42% (n = 163) of patients with inflammatory behavior at diagnosis had evolved to complicated behavior. During follow-up, 86% of patients (n = 466) received at least one course of corticosteroids, 67% (n = 357) of patients had been exposed to immunosuppressants and 35% (n = 187) of patients received at least one anti-TNF agent. Forty-three percent (n = 230) of patients underwent at least one intestinal resection. The overall mortality rate was 0.93% and the SMR was 1.6 [0.5-3.8] (p = 0.20). Five cancers were reported with a crude cancer incidence rate of 1.1% and an SIR of 3.3 [1.2-7.0] (p = 0.01). In a multivariate Cox model, ileal (HR, 1.87 [1.09-3.21], p = 0.022) or ileocolonic (HR, 1.54 [1.01-2.34], p = 0.042) and perianal lesions at diagnosis (HR, 1.81 [1.13- 2.89], p = 0.013) were significantly associated with complicated behavior. CONCLUSION About 80% of patients with pediatric-onset CD presented extensive ileocolonic disease during follow-up. The majority of patients evolved to complicated behavior. Surgery, cancer and mortality were observed in 43%, 0.9% and 0.9% of patients, respectively.

Abstract
Background A case is reported of innocuous intestinal obstruction requiring surgical intervention that was confirmed to be Crohn’s disease histopathologically in a resource-constrained rural mission hospital in Cameroon. Case presentation A 70-year man of Kumbo origin from Northwest region of Cameroon with a history of crampy right lower-quadrant abdominal pain, non-bloody, non-mucoid diarrhea alternating with constipation presented to my institution. Abdominal examination of the patient revealed an ill-defined mass in the right iliac fossa and visible peristalsis. An abdominal computed tomographic scan and barium enema study confirmed a complex ascending colonic and cecal tumor. The patient underwent exploratory laparotomy. The intraoperative finding was a huge complex inflammatory mass involving the cecum, terminal ileum, and sigmoid colon. He subsequently had sigmoidectomy with end–to-end sigmoidorectal anastomosis and a cecal resection, and the proximal ascending colon was exteriorized because end mucoid fistula and terminal ileostomy were performed. The histopathological diagnosis confirmed Crohn’s disease. The patient subsequently received five courses of adjuvant chemotherapy consisting of azathioprine, methotrexate, mesalamine, and methylprednisolone. He had complete disease remission and subsequently had closure of ileostomy with satisfactory postoperative status. The most recent follow-up abdominal computed tomographic scan and colonoscopy revealed disease-free status. The patient is also currently receiving a maintenance dose of rectal mesalamine and oral omeprazole treatment. He has been followed every 2 months in the surgical outpatient clinic over the last 16 months with satisfactory clinical outcome. Conclusions Crohn’s disease is uncommon in Africa, and this entity is encountered sparingly. The signs and symptoms of Crohn’s disease overlap with many other abdominal disorders, such as tuberculosis, ulcerative colitis, irritable bowel syndrome, and others. Several publications in the literature describe that it is difficult to make an accurate diagnosis of this disease, despite the fact that many diagnostic armamentaria are available to suggest its presence. Most of the patients with Crohn’s disease are treated conservatively, and a few may require surgical intervention, especially those presenting with complications such as intestinal obstruction, perforations, and abscess as well as fistula formations, as seen in this index patient. Crohn’s disease is considered by many to be a very rare disease in Africa. It is interesting to know that Crohn’s disease, which affects mainly young adults, may debut at any age. The rarity and clinical curiosity of this entity suggested reporting of my patient’s case. Evidence-based up-to-date information on Crohn’s disease is also documented.

Usefulness of Thiopurine Monotherapy for Crohn's Disease in the Era of Biologics: A Long-Term Single-Center Experience. Dig Dis Sci 2019; 64:875-879. [PMID: 30542812 DOI: 10.1007/s10620-018-5381-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2017] [Accepted: 11/14/2018] [Indexed: 12/23/2022]
Abstract
BACKGROUND Thiopurines are classically used in Crohn's disease (CD). Treatment fails in a proportion of patients either due to adverse events (AE) or lack of efficacy. Increasing use of anti-TNFα biologic drugs may have had impact on thiopurines usage. AIM To evaluate the evolving use of azathioprine (AZA) monotherapy in the era of biologics. METHODS The study retrospectively analyzed clinical records of all CD patients who started treatment with AZA monotherapy at our center since 1990. Dates of starting AZA and treatment failure (TF) were collected. We defined AZA TF if it was withdrawn due to lack of efficacy or AE, or biologics were added. RESULTS A total of 383 patients were included: 46.5% were males and mean age was 31 (range 17-84) years. Median follow-up was 43 (range 0.2-289) months. Overall, 147 patients (38%) experienced TF. Median cumulative survival time of AZA was 126 (95% CI 105-147) months. Proportion of patients with AZA TF increased along time: 7 patients in 1990-1995 (4.7% of all TF); 8 in 1996-2000 (5.4%); 22 in 2001-2005(15%); 41 in 2006-2010 (28%); 69 in 2011-2014 (47%) (p = 0.04). 7%, 21%, 4%, 45%, and 33.3% of patients moved to biologics in each period, respectively (χ2 = 13.07; p < 0.05). Seventy-four patients (18.4%) stopped AZA due to AE, and 73(19%) due to lack of efficacy. Regarding AZA indication, prevention of postoperative recurrence obtained better results than steroid dependency (p = 0.001); perianal fistulizing CD predicted poorer outcomes (p = 0.002). CONCLUSION An important proportion of CD patients under AZA monotherapy experienced TF in our experience. Although AZA monotherapy remains useful for CD in the era of biologics, current clinical practice is shifting to anti-TNFα biologic drugs in an increasing proportion of patients.

Abstract
OBJECTIVE The Epi-IBD cohort is a prospective population-based inception cohort of unselected patients with inflammatory bowel disease from 29 European centres covering a background population of almost 10 million people. The aim of this study was to assess the 5-year outcome and disease course of patients with Crohn's disease (CD). DESIGN Patients were followed up prospectively from the time of diagnosis, including collection of their clinical data, demographics, disease activity, medical therapy, surgery, cancers and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. RESULTS In total, 488 patients were included in the study. During follow-up, 107 (22%) patients received surgery, while 176 (36%) patients were hospitalised because of CD. A total of 49 (14%) patients diagnosed with non-stricturing, non-penetrating disease progressed to either stricturing and/or penetrating disease. These rates did not differ between patients from Western and Eastern Europe. However, significant geographic differences were noted regarding treatment: more patients in Western Europe received biological therapy (33%) and immunomodulators (66%) than did those in Eastern Europe (14% and 54%, respectively, P<0.01), while more Eastern European patients received 5-aminosalicylates (90% vs 56%, P<0.05). Treatment with immunomodulators reduced the risk of surgery (HR: 0.4, 95% CI 0.2 to 0.6) and hospitalisation (HR: 0.3, 95% CI 0.2 to 0.5). CONCLUSION Despite patients being treated early and frequently with immunomodulators and biological therapy in Western Europe, 5-year outcomes including surgery and phenotype progression in this cohort were comparable across Western and Eastern Europe. Differences in treatment strategies between Western and Eastern European centres did not affect the disease course. Treatment with immunomodulators reduced the risk of surgery and hospitalisation.

Association between use of azathioprine and risk of acute pancreatitis in children with inflammatory bowel disease: a Swedish-Danish nationwide cohort study. THE LANCET CHILD & ADOLESCENT HEALTH 2019; 3:158-165. [PMID: 30685366 DOI: 10.1016/s2352-4642(18)30401-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Revised: 11/27/2018] [Accepted: 11/29/2018] [Indexed: 01/16/2023]
Abstract
BACKGROUND Studies have shown an association between use of azathioprine and increased risk of acute pancreatitis in adult inflammatory bowel disease. However, whether an association exists among paediatric patients is not known. We aimed to investigate whether use of azathioprine is associated with the risk of acute pancreatitis in children with inflammatory bowel disease. METHODS We did a nationwide register-based cohort study in Sweden (2006-16) and Denmark (2000-16). All paediatric patients (<18 years of age) with inflammatory bowel disease during the study period were identified through hospital records. Episodes of incident azathioprine use and no use of any thiopurine were matched (1:1) using propensity scores, controlling for sociodemographic characteristics, comorbidities, previous treatment, indicators of disease severity, and health care use. Incident acute pancreatitis (physician-assigned diagnosis with ICD-10 code K85) occurring in the 90 days following treatment initiation were identified through outpatient and inpatient hospital records. FINDINGS We identified 3574 azathioprine episodes and 18 700 no-use episodes, which resulted in 3374 pairs after propensity score matching; baseline characteristics in the matched cohort were well balanced. Among the matched azathioprine episodes, mean age was 14·3 years (SD 3·1), 1854 (54·9%) were male, 1923 (57·0%) had Crohn's disease, and 1451 (43·0%) had ulcerative colitis or unclassified inflammatory bowel disease. Within the first 90 days following initiation of azathioprine, 40 acute pancreatitis events occurred (incidence rate 49·1 events per 1000 person-years) compared with six events in the no-use group (8·4 events per 1000 person-years). Azathioprine use was associated with an increased risk of acute pancreatitis (incidence rate ratio 5·82 [95% CI 2·47-13·72]; absolute difference 1·0 [95% CI 0·3-2·6] events per 100 patients) during the 90-day risk period. INTERPRETATION Use of azathioprine was associated with an increased risk of acute pancreatitis in children with inflammatory bowel disease during the first 90 days following treatment initiation, suggesting the need for regular and rigorous monitoring. The risk of acute pancreatitis needs to be considered when deciding on optimal treatment strategies. FUNDING Swedish Research Council, Frimurare Barnhuset Foundation, and the Åke Wiberg Foundation.

Abstract
The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for acute abscesses, active fistulas (active denovo and still active under treatment), fistulas in remission, and rectovaginal fistulas are suggested. Recommendations have been graded following the international recommendations, and when absent, professional agreement has been established. For each situation, practical algorithms have been drawn.

Abstract
BACKGROUND Thiopurine metabolite monitoring to proactively dose optimize to achieve therapeutic levels has not been used consistently, and it is unclear if this would lead to better outcomes. We aimed to compare 6-month outcomes between standard and optimized dosing strategies and define long-term predictors of thiopurine durability. METHODS Two hundred sixteen pediatric IBD patients with at least 2 6-thioguanine nucleotide (6-TGN) levels were grouped for analysis by start dose: >2.5 mg/kg/day AZA (group 1) or <2.5 mg/kg/day (group 2) and further subgrouped depending on whether dosing was optimized to achieve 6-TGN >235 pmol/8 × 108 RBC. The metabolites, 6TGN and 6MMP, were univariate and multivariate analyses tested associations among metabolite levels, laboratory data, and the primary outcome of 6-month steroid-free clinical remission (SFR) (HBI ≤4 for CD; partial Mayo Score [pMS] ≤2 for UC). Thiopurine durability was measured using Kaplan Maier survival analysis. RESULTS 6-MP, azathioprine, pediatrics, therapeutic drug monitoring, pediatrics were measured a median 59 (43-76) days after initiation of thiopurine. Both dosing strategies led to similar initial 6-TGN levels (group 1 = median 209 [IQR: 155-272] with 25% of patients >235; group 2 = 196 [139-274] with 29% >235). Steroid-free clinical remission was achieved in 74% of the 180 still on thiopurines at 6 months. Start dose was not associated with 6-month SFR-73% in group 1 and 77% in group 2 within those on thiopurines at 6 months (P = 0.61). Fixed- and optimized-dosing subgroups had similar 6-month 6-TGN levels, SFR rate, and percentage 6-TGN > 235. Only 6-TGN level >235 at 6 months predicted thiopurine durability (3 years [1.7-7.7] vs 2.5 years [0.83-5]; log-rank P < 0.001), and this did not retain significant in a multivariate model. Initial dosing strategy, first 6-TGN level, 6-month SFR, 6MMP:6TGN ratio, and delta-MCV did not predict durability. The rate of adverse events was 22%. CONCLUSIONS Steroid-free clinical remission and 6-TGN levels at 6 months were no different between a standardized, fixed dosing strategy and a metabolite-driven, optimized dosing strategy.

Abstract
BACKGROUND The need for immune suppressive strategies in the control of chronic inflammatory bowel diseases originated in the 1960s following the perception of a relative inefficacy of salazopyrin and its derivatives. In some 50 years upon an anecdotal claim, the indication for thiopurines in the management of inflammatory bowel diseases has come of age. OBJECTIVE The aim of this minireview is to give an overview, after the historical premises, of the current use of thiopurines in the context of inflammatory bowel diseases. METHOD Through MEDLINE searches, we reviewed the literature of the last two decades. RESULTS For Crohn's disease, the 1980 trial of 6-mercaptopurine for steroid sparing and fistula closure proved pivotal. The analysis of withdrawal experiments and of numerous open trials has established the efficacy of thiopurines for ulcerative colitis. In this indication, cutting-edge data are now showing that because targeting dysplasia, thiopurines can induce mucosal/histological healing, thus abolishing or delaying the need for pre-emptive (tumor prophylactic) colectomy. CONCLUSION In UC thiopurines may be recognized to effect a treat-to-target strategy, joining the modern algorithms of rheumatologic disorders.

Abstract
Thiopurines (azathioprine, mercaptopurine, thioguanine) and methotrexate are widely used in a variety of clinical management scenarios for ulcerative colitis and Crohn's disease. With the introduction of biologic therapies over the last 2 decades, controversies have emerged as to how these immunomodulators should be used in clinical practice, either alone as monotherapies or in combination with biologic therapies. Here, we provide a summary of evidence and our interpretations regarding how physicians can or should incorporate these agents into clinical practice. We have organized the review into sections regarding their utility as monotherapy or as combination therapy with biologics and safety considerations. Clinical pharmacologic considerations are important regarding both efficacy and safety.

Exclusive enteral nutrition with concomitant early thiopurine use was effective in maintaining steroid-free remission in a Southeast Asian cohort of children with Crohn's disease. BMC Gastroenterol 2018; 18:185. [PMID: 30541458 PMCID: PMC6292012 DOI: 10.1186/s12876-018-0907-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2017] [Accepted: 11/13/2018] [Indexed: 12/31/2022] Open
Abstract
Background Exclusive enteral nutrition (EEN) is as effective as corticosteroids in inducing remission in children with Crohn’s disease (CD). However, over 50% of these children relapse by 12 months of diagnosis. Thiopurines are commonly prescribed as maintenance therapy for CD, but evidence for its efficacy is controversial. Data on the effectiveness of EEN in Southeast Asian (SEA) children with CD is scarce. This study aims to evaluate the efficacy of EEN induction therapy in a cohort of SEA children with newly diagnosed CD. The secondary aim was to evaluate concomitant early azathioprine (EAZ) use in determining remission rate at 6 and 12 months. Methods Case records of all children with newly diagnosed CD from 2011 to 2014 were reviewed and relevant demographic as well as clinical data were extracted. The primary outcome measure was the number of patients who completed EEN induction therapy and achieved remission (Paediatric Crohn’s Disease Activity Index; PCDAI≤10). Factors influencing duration of remission were evaluated in particular early azathioprine (EAZ) defined as starting azathioprine within one month of diagnosis versus late azathioprine (LAZ) use. Results Forty children with newly diagnosed CD were identified. Thirty-three children: 67% boys, median age 13y (range 3–17) completed 8 weeks of EEN induction therapy and 91% achieved remission. Significant improvements were seen in PCDAI scores (32.7 ± 9.2 to 4.2 ± 5.1; p < 0.001), mean BMI z-score (− 1.38 ± 1.57 to − 0.82 ± 1.27; p = 0.004) and baseline inflammatory markers: Erythrocyte Sedimentation Rate (51.6 ± 30.1 mm/h to 13.3 ± 7.1 mm/h; p < 0.0001) C-Reactive Protein (44.6 ± 51.0 mg/L to 5.2 ± 7.6 mg/L; p = 0.001), Albumin (30.7 ± 7.5 g/L to 38.7 ± 3.9 g/L; p < 0.0001), Platelets (464 ± 161 × 109 to 370 ± 111 × 109; p < 0.0001),. Early azathioprine initiation was associated with a remission rate of 80 and 73% at 6 and 12 months respectively. Remission was also maintained for longer duration in EAZ vs LAZ groups (p = 0.048). Conclusion EEN effectively induces remission in this cohort of SEA children with newly diagnosed CD. Early initiation of thiopurine with EEN induction therapy is effective in maintaining steroid-free remission for at least one year.

Abstract
BACKGROUND Paediatric Crohn's disease is characteried by frequently relapsing disease which may lead to hospitalisations and complications. AIM To develop predictive models for early relapse following first remission. METHODS The GROWTH CD prospective inception cohort was designed to predict risk for early disease relapse and poor outcomes. Newly diagnosed children underwent endoscopies and imaging. They were phenotyped and followed at scheduled visits through 78 weeks for relapses. Twenty-eight dichotomous and continuous variables were assessed at baseline and week 12, including phenotype, inflammatory markers, disease activity (PCDAI) and other markers. Clinical relapses defined as PCDAI >10 after remission were recorded using a relapse form. Logistic regression & risk modelling was performed. RESULTS We enrolled 282 eligible patients of whom 178 (63.6%) patients achieved steroid free remission by week 12. Disease complications developed in 22/76(29%) of patients with relapse compared to 20/206 (9.7%) without relapse (P = 0.01). Multivariable analysis demonstrated that while variables from age/gender at diagnosis were not predictive, week 12 variables including PCDAI >5 (P = 0.02), CRP >20 mg/L (P = 0.02), and faecal calprotectin >400 µg/g (P = 0.03) as optimal cut-offs were associated with increased risk of relapse. A prediction model for patients in remission including gender, age, week 12 PCDAI, calprotectin and CRP had sensitivity 43%, specificity 92%, PPV 78%, NPV 71% for relapse. CONCLUSIONS Early relapses were associated with a higher risk for disease complications at followup. Relapse prediction based on week 12 disease activity or inflammation is superior to prediction using data from diagnosis.

Abstract
AIMS To describe the characteristics of patients with Crohn's disease (CD) in non-academic hospitals in France and to evaluate how therapeutic practices changed between 1999 and 2013. METHODS During 2 weeks in September 2013, we solicited disease and treatment information for CD patients seen by gastroenterologists in 57 French non-academic hospitals. In four groups of patients defined according to the date of CD diagnosis (<1999, 1999-2003, 2004-2008, and 2009-2013), the use of immunosuppressor (IS) and anti-TNF treatments during the first 5 years following diagnosis of CD was compared using the Kaplan-Meier method. RESULTS 739 consecutive CD patients (median age at diagnosis 25.4 years) were included in the survey. CD location was ileal for 31%, colonic for 21%, and ileocolonic for 45%. CD phenotypes were non-penetrating/non-stricturing (58.7%), stricturing (26.9%), and penetrating (12.7%), with perianal lesions in 26.1%. The proportions of patients who began IS or anti-TNF treatment within 5 years of diagnosis increased significantly from 18% and 0%, respectively, in <1999 (n=170) to 52% and 23% in 1999-2003 (n=120), 66% and 70% in 2004-2008 (n=155), and 75% and 100% in 2009-2013 (n=294; P<0.0001). CONCLUSIONS In this French non-academic hospital cohort of CD patients, the proportions of patients being treated with anti-TNF or IS therapy in the first 5 years after diagnosis both increased sharply since 1999.

Abstract
BACKGROUND & AIMS Endpoints in randomized controlled trials (RCTs) of Crohn's disease (CD) are changing. We performed a systematic review of efficacy and safety outcomes reported in placebo-controlled RCTs of patients with CD. METHODS We searched the MEDLINE, EMBASE, and the Cochrane Library through March 1, 2017 for placebo-controlled RCTs of adult patients with CD treated with aminosalicylates, immunomodulators, corticosteroids, biologics, and oral small molecules. Efficacy and safety outcomes, definitions, and measurement tools were collected and stratified by decade of publication. RESULTS Our final analysis included 116 RCTs (81 induction, 44 maintenance, 7 postoperative prevention trials, comprising 27,263 patients). Clinical efficacy endpoints were reported in all trials; the most common endpoint was CD activity index score. We identified 38 unique definitions of clinical response or remission and 32 definitions of loss of response. Definitions of endoscopic response, remission, and endoscopic healing were also heterogeneous, evaluated using the CD endoscopic index of severity, the simple endoscopic score for CD, ulcer resolution, and Rutgeerts' Score for postoperative endoscopic appearance. Histologic outcomes were reported in 11.1% of induction trials, 2.3% of maintenance trials, and 14.3% of postoperative prevention trials. Biomarker outcomes were reported in 81.5% induction trials, 68.2% of maintenance trials, and 42.9% of postoperative prevention trials. Safety outcomes were reported in 93.8% of induction trials, 97.7% of maintenance trials, and 85.7% of postoperative prevention trials. CONCLUSIONS In this systematic review, we demonstrate heterogeneity in definitions of response and remission, and changes in outcomes reported in RCTs of CD. It is a priority to select a core set of outcomes to standardize efficacy and safety evaluation in trials of patients with CD.

Abstract
Immunosuppressive therapy (IM) is inexpensive and nearly one-third of patients with inflammatory bowel disease (IBD) experience a benefit from treatment. IM may be ideal for IBD patients at low risk for a disabling disease course or colectomy and/or those patients with inadequate access to biologic therapy. A majority of IBD patients benefit from early biologic therapy with improved short and likely long-term outcomes. Improved methods are needed to identify patients at the greatest risk for a severe disease course and that are likely to respond to the various forms of small molecule and biologic treatments. Health systems need to identify innovative methods to contain costs of biologic therapy.

Abstract
Background & Aims Crohn’s disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. Methods We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a group of specialists. Results The consensus includes 41 statements focused on 6 main drug classes: antibiotics, 5-aminosalicylate, corticosteroids, immunosuppressants, biologic therapies, and other therapies. The group suggested against the use of antibiotics or 5-aminosalicylate as induction or maintenance therapies. Corticosteroid therapies (including budesonide) can be used as induction, but not maintenance therapies. Among immunosuppressants, thiopurines should not be used for induction, but can be used for maintenance therapy for selected low-risk patients. Parenteral methotrexate was proposed for induction and maintenance therapy in patients with corticosteroid-dependent CD. Biologic agents, including tumor necrosis factor antagonists, vedolizumab, and ustekinumab, were recommended for patients failed by conventional induction therapies and as maintenance therapy. The consensus group was unable to clearly define the role of concomitant immunosuppressant therapies in initiation of treatment with a biologic agent. Conclusions Optimal management of CD requires careful patient assessment, acknowledgement of patient preferences, evidence-based use of existing therapies, and thorough assessment to define treatment success.

Abstract
GOALS The aim of this study was to assess whether sustained 6-thioguaninenucleotide (6-TGN) levels were associated with improved long-term outcomes in patients with inflammatory bowel diseases (IBD). BACKGROUND Cross-sectional data have shown that thiopurine metabolites are correlated with clinical efficacy in patient receiving thiopurines for IBD but the role for serial measurements through treatment course is unclear. STUDY We conducted a retrospective cohort study including patients with IBD on thiopurine monotherapy and had serial 6-TGN levels measured. Predictive variables included demographics, disease phenotype, 6-TGN levels (nadir, median, and peak levels). The primary outcome was the development of a disease relapse. The secondary outcome was the need for IBD surgery. RESULTS Two hundred eighteen 6-TGN samples from 87 patients were analyzed. Nadir and median 6-TGN levels were significantly higher in patients who did not relapse [185 and 233 pmol per 8×10 red blood cells (RBCs)] as compared with levels in patients who did relapse (150 and 167 pmol per 8×10 RBCs, P=0.025) but there was no significant difference in peak 6-TGN level. When adjusted for confounding factors, a nadir 6-TGN level ≥161 and a median 6-TGN level ≥264 were associated with a significant decrease in the rate of disease exacerbation (hazard ratio: 0.5; 95% confidence interval, 0.26-0.87; P=0.016 and hazard ratio: 0.4; 95% confidence interval, 0.2-0.82; P=0.14). CONCLUSIONS Serial thiopurine metabolite level assessments and dose adjustment aiming to maintain higher 6-TGN levels may be helpful to improve long-term outcomes in patients with IBD.

Long-term Outcome of Early Combined Immunosuppression Versus Conventional Management in Newly Diagnosed Crohn's Disease. J Crohns Colitis 2018; 12:517-524. [PMID: 29401297 DOI: 10.1093/ecco-jcc/jjy014] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Accepted: 01/25/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIMS Long-term outcomes of early combined immunosuppression [top-down] compared to conventional management [step-up] in recently diagnosed Crohn's disease [CD] are unknown. We aimed to investigate long-term outcomes of participants of the Step-up/Top-down-trial. METHODS Trial participants' medical records were reviewed retrospectively. For 16 semesters following the 2-year trial, we recorded: clinical activity, medication use, flares, hospitalization, surgery and fistulas. Colonoscopy reports were scored as: endoscopic remission, aphthous/small ulcers or large ulcers. The primary endpoint was the proportion of semesters in remission. RESULTS Data were available from 119/133 patients [step-up n = 60]. During a median follow-up of 8 years, clinical remission rates were similar (70% vs 73% [p = 0.85] in step-up and top-down patients, respectively). A shorter time to flare was observed in step-up patients [median five vs nine semesters, p = 0.01]. Cumulatively, 62% of step-up patients used corticosteroids compared to 41% of top-down patients [p = 0.02]. Anti-tumour necrosis factor [anti-TNF] use was higher in the step-up group [73% vs 54%, p = 0.04]. No differences were found in to time to CD hospitalization [respectively 13 vs 14 semesters, p = 0.30], new fistula [14 vs 15 semesters, p = 0.20] or CD surgery [14 vs 15 semesters, p = 0.25]. Mucosal healing 2 years after treatment was associated with a reduced anti-TNF use, but not with differences in other long-term outcomes. Endoscopic remission occurred at similar rates between groups. CONCLUSIONS Top-down treatment did not result in increased clinical remission during long-term follow-up, compared to step-up treatment. However, lower relapse rates and a reduced use of anti-TNF agents and corticosteroids were observed. No difference was found in rates of endoscopic remission, hospitalization, surgery or new fistulas.

Abstract
BACKGROUND Thiopurine hypermethylation towards 6-methylmercaptopurine (6MMP) instead of 6-thioguanine nucleotides (6TGN) is associated with inefficacy in patients with IBD. Allopurinol reverses such hypermethylation. AIMS To prospectively determine efficacy of allopurinol-thiopurine combination and to compare 2 doses of allopurinol. DESIGN In a multicentre, double-blind trial, patients with clinically active or steroid-dependent IBD and thiopurine shunting were randomised to 50 or 100 mg/d allopurinol and 25% of their screening thiopurine dose, which was subsequently optimised, aiming for 6TGN of 260-500 pmol/8x108 RBCs. The primary endpoint was steroid-free clinical remission at 24 weeks. RESULTS Of 73 patients, 39 (53% [95% CI 42-65]) achieved steroid-free remission, (54% with 50 mg/d and 53% with 100 mg/d). 81% were able to discontinue steroids. Therapeutic 6TGN levels were achieved in both groups. Final thiopurine doses were lower with 100 mg/d allopurinol (P < 0.005). 6MMP: 6TGN ratio decreased from mean 64 to 4 (P < 0.001), being higher with 50 mg/d (6 ± 1.83) than for 100 mg/d ([1 ± 0.16], P = 0.003). Three patients on 50 mg/d failed to sustain low ratios at 24 weeks. Toxicity was minimal; three patients on 50 mg/d allopurinol developed transient leukopenia. Alanine aminotransferase concentrations decreased (P < 0.001) similarly in both arms. Faecal calprotectin levels at study end were lower in patients who achieved the primary endpoint (median 171 [85-541] vs 821[110-5892] ug/g, P = 0.03). CONCLUSIONS Low-dose allopurinol-thiopurine combination safely reverses shunting and optimises 6TGN with associated improvement in disease activity. 100 mg/d allopurinol is preferable due to greater metabolite profile stability and lower thiopurine dose without additional toxicity.

Abstract
BACKGROUND AND AIMS Endoscopic balloon dilation [EBD] is an alternative to surgery for Crohn's strictures. However, there have been no prospective studies of EBD for small bowel strictures in patients with Crohn's disease [CD]. The aim of this study was to clarify the efficacy and safety of EBD using balloon-assisted enteroscopy for small bowel strictures in CD. METHODS This was a nationwide, multi-centre, open-label, prospective cohort study. The subjects were CD patients with at least one symptom [abdominal pain, abdominal bloating, nausea] attributable to small bowel stricture. The primary endpoint related to short-term outcomes was the level of improvement of symptoms evaluated using a 10-cm visual analogue scale [VAS]. Cases in which VAS scores for all symptoms improved 4 weeks after EBD compared with baseline were considered to have short-term symptomatic improvement. Factors related to short-term treatment outcomes and safety were investigated as secondary endpoints. RESULTS A total of 112 patients were enrolled. Seventeen were later excluded because they did not meet the criteria, and the analysis was conducted with the remaining 95 patients. Of these 95 patients, procedure failure occurred in six [6.3%], and short-term symptomatic improvement was achieved in 66 patients [69.5%]. Adverse events were seen in five patients [5%] and all of these improved with conservative treatment. A large dilation diameter of the balloon was a factor contributing to the success of EBD. CONCLUSIONS EBD using balloon-assisted enteroscopy for small bowel strictures in CD patients was shown to be an effective and safe procedure. CLINICAL TRIAL REGISTRY UMIN000005946.

Abstract
The management of Crohn's disease involves immunosuppressive protocols in a step-up approach that progresses through a therapeutic pyramid with several tiers of medication. Medications at the top are considered more potent but present greater risk. A new top-down approach to therapy inverts this procedure, using top-tier drugs for initial treatment. A critical appraisal of the current literature relating to top-down therapy was performed to evaluate its merit. A literature search was conducted on PubMed, Ovid, and PubMed Central to identify studies of the efficacy of top-down therapy. Papers were appraised critically using the Scottish Intercollegiate Guidelines Network score to evaluate current evidence for the use of top-down therapy. Nineteen studies were identified, including six randomized controlled trials, thirteen cohort studies, and two cost-benefit studies. Early combined therapy involving both biologics and immunomodulators was found to be effective at improving patient outcomes; however, early biologics alone were not shown to have a clear benefit over step-up therapy. Likewise, the early use of immunomodulators alone showed inconsistent results with respect to efficacy in terms of both remission and surgical outcomes. Evidence for application in pediatric populations was also inconclusive. The cost-benefit analyses found that top-down therapy merits investigation, as it proved to be economical given current data. Top-down therapy has the potential of being a viable alternative to step-up therapy, but further studies are needed to determine the most appropriate patients to receive this treatment.

Abstract
BACKGROUND AND AIM Whether an early use of azathioprine (AZA) can alter the natural history of Crohn's disease (CD) remains debated. The aim of this study is to evaluate the impact of AZA on disease progression in a cohort of patients with early CD. METHODS This longitudinal cohort study examined patients with early CD defined as disease duration ≤ 18 months and no previous use of disease-modifying agents according to Paris definition. The primary outcome was the proportion of CD-related intestinal surgery. Cox regression analysis was performed to identify potential predictive factors of CD progression. RESULTS One-hundred and ninety patients with early CD were enrolled in the study. After a median follow-up of 57 months (interquartile range, 31.3-76.2), 31 patients underwent abdominal surgeries, 48 patients were hospitalized, and 68 patients experienced clinical flares. The cumulative rate of remaining free of CD-related bowel surgery, hospitalization, and flare at 5 years on AZA treatment was 0.65, 0.59, and 0.39, respectively. Three independent predictors of CD-related operations were identified: prior bowel resection (hazard ratio [HR], 9.23; 95% confidence interval [CI] 3.67-23.23), smoker (HR, 4.0; 95% CI 1.38-11.65), and hemoglobin < 110 g/L at the time of initiation of AZA (HR, 4.36; 95% CI 1.80-10.58). Conversely, AZA treatment duration > 36 months (HR, 0.04; 95% CI 0.01-0.15) was associated with reduced CD-related operations. CONCLUSION Prior bowel resection, smoking, and hemoglobin < 110 g/L at the time of initiation of AZA were risk factors associated with intestinal surgery in patients with early CD. However, prolonged use (≥ 36 months) of AZA was associated with a more favorable disease course of early CD.

Abstract
Thiopurines (azathioprine and mercaptopurine) are widely used in patients with inflammatory bowel disease. In this paper, we review the main indications for their use, as well as practical aspects on efficacy, safety and method of administration. They are mainly used to maintain remission in steroid-dependent disease or with ciclosporin to control a severe ulcerative colitis flare-up, as well as to prevent postoperative Crohn's disease recurrence, and also in combination therapy with biologics. About 30-40% of patients will not respond to treatment and 10-20% will not tolerate it due to adverse effects. Before they are prescribed, immunisation status against certain infections should be checked. Determination of thiopurine methyltransferase activity (TPMT) is not mandatory but it increases initial safety. The appropriate dose is 2.5mg/kg/day for azathioprine and 1.5mg/kg/day for mercaptopurine. Some adverse effects are idiosyncratic (digestive intolerance, pancreatitis, fever, arthromyalgia, rash and some forms of hepatotoxicity). Others are dose-dependent (myelotoxicity and other types of hepatotoxicity), and their surveillance should never be interrupted during treatment. If therapy fails or adverse effects develop, management can include switching from one thiopurine to the other, reducing the dose, combining low doses of azathioprine with allopurinol and assessing metabolites, before their use is ruled out. Non-melanoma skin cancer, lymphomas and urinary tract tumours have been linked to thiopurine therapy. Thiopurine use is safe during conception, pregnancy and breastfeeding.

Abstract
Background/Aims The use of anti-tumor necrosis factor (anti-TNF) agents seems to reduce surgical rates and delay surgical procedures in prospective trials and population-based studies in the management of Crohn's disease (CD). This study aimed to identify whether preoperative anti-TNF agents influence the time from diagnosis to surgery. Methods An observational retrospective cohort study was conducted on patients with CD submitted to intestinal resections due to complications or medical therapy failure in a period of 7 years. The patients were allocated into 2 groups according to their previous exposure to anti-TNF agents in the preoperative period. Epidemiological aspects regarding age at diagnosis, smoking, perianal disease, and preoperative conventional therapy were considered. A Kaplan-Meier survival analysis was used to outline possible differences between the groups regarding the time to surgery. Results A total of 123 patients were included (71 and 52 with and without previous exposure to biologics, respectively). The overall time to surgery was 108±6.9 months (maximum, 276 months). The survival estimation revealed no difference in the mean time to intestinal resection between the groups (99.78±10.62 months in the patients without and 114.01±9.07 months in those with previous anti-TNF use) (log-rank P=0.35). There was no significant difference in the time to surgery regarding perianal CD (P=0.49), smoking (P=0.63), preoperative azathioprine (P=0.073) and steroid use (P=0.58). Conclusions The time from diagnosis to surgery was not influenced by the preoperative use of anti-TNF therapy in this cohort of patients.

Abstract
Inflammatory bowel diseases (IBD) are chronic autoimmune conditions of the gut affecting both pediatric and adult patients. Medical therapy is often successful at inducing and maintaining remission and preventing disease complications. The mainstays of treatment are medications and other therapies that reduce inflammation and suppress the overactive immune system. Here we review current medical therapies for pediatric IBD, discuss future therapeutics, and present current treatment goals and approaches.

Abstract
Crohn's disease (CD) is a chronic progressive destructive inflammatory bowel disease. As in rheumatoid arthritis, there is increasing evidence that early treatment initiation with disease-modifying agents, such as biological drugs, may lead to complete disease control, prevention of disease progression thus protecting against irreversible damage and restoration of normal quality of life. Data from randomised clinical trials with immunosuppressants and biologics suggest that treating patients with a disease duration of <2 years and an absence of complications may significantly reduce the risk for complications and increase time in remission in patients with CD. Moreover, rapid disease control may effectively prevent disease progression and allow dose reduction or even withdrawal of treatment, reducing the risk of long-term adverse events and healthcare costs. However, prospective disease modification trials are needed to confirm these initial results. Here we review the literature regarding early intervention in adult patients with CD and propose criteria for future disease modification trials.

Abstract
Disability is a common worldwide health challenge and it has been increasing over the past 3 decades. The treatment paradigm has changed dramatically in inflammatory bowel diseases (IBDs) from control of symptoms towards full control of disease (clinical and endoscopic remission) with the goal of preventing organ damage and disability. These aims are broadly similar to rheumatoid arthritis and multiple sclerosis. Since the 1990s, our attention has focused on quality of life in IBD, which is a subjective measure. However, as an objective end-point in clinical trials and population studies, measures of disability in IBD have been proposed. Disability is defined as '…any restriction or lack (resulting from an impairment) of ability to perform an activity in the manner or within the range considered normal for a human being.' Recently, after 10 years of an international collaborative effort with the World Health Organization (WHO), a disability index was developed and validated. This index ideally would assist with the assessment of disease progression in IBD. In this review, we will provide the evidence to support the use of disability in IBD patients, including experience from rheumatoid arthritis and multiple sclerosis. New treatment strategies, and validation studies that have underpinned the interest and quantification of disability in IBD, will be discussed.

Concomitant Therapy with Immunomodulator Enhances Infliximab Durability in Pediatric Inflammatory Bowel Disease. Inflamm Bowel Dis 2017; 23:1762-1773.

Abstract
BACKGROUND Data on long-term durability of infliximab (IFX) and outcomes of concomitant therapy with immunomodulator in pediatric inflammatory bowel disease are limited. METHODS Children with inflammatory bowel disease who received IFX ± immunomodulator were retrospectively reviewed. Predictors of induction response were assessed using a binary logistic regression model and long-term outcomes evaluated by Cox proportional hazards model. Propensity score matching examined long-term efficacy of concomitant therapy in patients with Crohn's disease (CD). RESULTS Among 148 patients (113 CD, 35 ulcerative colitis; median age at IFX initiation 14.09 years [interquartile range 12.16-15.65]), 91% experienced response to induction therapy; patients with CD were more likely to respond (95% versus 77%, odds ratio = 2.63, 95% confidence interval, 1.01-6.85, P = 0.048). Despite dose optimization, secondary loss of response occurred at a rate of 9.01% and 8.33% per year for patients with CD and ulcerative colitis, respectively. A Cox proportional hazards model showed that concomitant therapy >6 months significantly lowered the risk of secondary loss of response in CD (hazard ratio = 0.39, 95% confidence interval, 0.17-0.88, P = 0.025). The same trend was observed in ulcerative colitis but did not reach significance. A higher proportion of patients on IFX monotherapy stopped IFX because of loss of response or infusion reactions (55% versus 21%, P < 0.001). Propensity score analysis of patients with CD showed significantly higher steroid-free remission rates for concomitant versus monotherapy at 1 year (78% versus 54%, P = 0.020) and 2 years (68% versus 46%, P = 0.044), and durability of response (P = 0.022). CONCLUSIONS These data demonstrate sustained efficacy of IFX in a cohort of pediatric patients with inflammatory bowel disease with durability of response enhanced by concomitant therapy.

Abstract
Despite advances in care, most patients with Crohn's disease (CD) develop complications, such as fistulas, or require surgery. Given the recent advances in drug therapy, an opportunity exists to optimize the management of this chronic disease through early use of effective therapies, clear definition of treatment targets, and application of the principles of personalized medicine. In this article, the authors discuss the evolution of treatment algorithms for CD to incorporate these strategies.

Abstract
Crohn disease is a chronic idiopathic inflammatory bowel disease condition characterized by skip lesions and transmural inflammation that can affect the entire gastrointestinal tract from the mouth to the anus. For this review article, we performed a review of articles in PubMed through February 1, 2017, by using the following Medical Subject Heading terms: crohns disease, crohn's disease, crohn disease, inflammatory bowel disease, and inflammatory bowel diseases. Presenting symptoms are often variable and may include diarrhea, abdominal pain, weight loss, nausea, vomiting, and in certain cases fevers or chills. There are 3 main disease phenotypes: inflammatory, structuring, and penetrating. In addition to the underlying disease phenotype, up to a third of patients will develop perianal involvement of their disease. In addition, in some cases, extraintestinal manifestations may develop. The diagnosis is typically made with endoscopic and/or radiologic findings. Disease management is usually with pharmacologic therapy, which is determined on the basis of disease severity and underlying disease phenotype. Although the goal of management is to control the inflammation and induce a clinical remission with pharmacologic therapy, most patients will eventually require surgery for their disease. Unfortunately, surgery is not curative and patients still require ongoing therapy even after surgery for disease recurrence. Importantly, given the risks of complications from both Crohn disease and the medications used to treat the disease process, primary care physicians play an important role in optimizing the preventative care management to reduce the risk of complications.

Abstract
PURPOSE OF REVIEW The aim of this review is to summarize data regarding surgical trends in inflammatory bowel disease in the prebiologic and biologic era, with a focus on population-based studies and randomized controlled trials (RCTs). RECENT FINDINGS There is paucity of data in RCTs regarding surgical rates, with only a few clinical trials reporting them. From the available data, meta-analyses of RCTs have concluded that antitumor necrosis α agents (anti-TNF) reduce surgical rates in ulcerative colitis and Crohn's disease. A large body of evidence from population-based studies from different regions of the world is available to evaluate surgical trends before and after the introduction of anti-TNF agents. The risk of surgery decreased significantly over the past six decades; these decreasing trends continued in the biologic era, which might indicate a potential beneficial disease-modifying effect of biologics. There is lack of data with nonanti-TNF biologics (i.e. anti-integrins and ustekinumab) regarding the risk of surgery. SUMMARY Although data from population-based studies and available RCTs suggest a protective effect from surgery of anti-TNF agents, definitive conclusions should be drawn only when more disease-modifying trials with different biologics and treatment strategies become available.

Infliximab Is Not Associated With Increased Risk of Malignancy or Hemophagocytic Lymphohistiocytosis in Pediatric Patients With Inflammatory Bowel Disease. Gastroenterology 2017; 152:1901-1914.e3.

Abstract
BACKGROUND AND AIMS Immunosuppressive therapy for inflammatory bowel disease (IBD) in pediatric patients is thought to increase the risk of malignancy and lymphoproliferative disorders, including hemophagocytic lymphohistiocytosis (HLH). We compared unadjusted incidence rates of malignancy and HLH in pediatric patients with IBD exposed to infliximab (IFX) with patients not exposed to biologics and calculated standardized incidence ratios (SIRs). METHODS We collected and analyzed data from 5766 participants in a prospective study of long-term outcomes of pediatric patients with IBD (NCT00606346), from May 31, 2007 through June 30, 2016. Patients were 17 years old or younger and had Crohn's disease, ulcerative colitis, or IBD-unclassified with 24,543.0 patient-years of follow-up. We estimated incidence rates for malignancy and HLH as events/1000 patient-years of follow-up. We calculated age-, sex-, and race-adjusted SIRs, with 95% confidence intervals (CIs), using the Surveillance, Epidemiology, and End Results Program (SEER) database. RESULTS Thirteen of the 15 patients who developed a malignancy and all 5 of the patients who developed HLH had been exposed to thiopurines; 10 patients with malignancy had also been exposed to a biologic agent. Unadjusted incidence rates showed no increased risk of malignancy (0.46/1000 patient-years) or HLH (0.0/1000 patient-years) in patients exposed to IFX as the only biologic vs those unexposed to biologics (malignancy: 1.12/1000 patient-years; HLH: 0.56/1000 patient-years). SIRs did not demonstrate an increased risk of malignancy among patients exposed to IFX (SIR, 1.69; 95% CI, 0.46-4.32) vs patients not exposed to a biologic agent (SIR, 2.17; 95% CI, 0.59-5.56), even when patients were stratified by thiopurine exposure. CONCLUSIONS In determination of age-, sex-, and race-adjusted SIRs using data from a large clinical study and the SEER database, we found that IFX exposure did not associate with increased risk of malignancy or HLH in pediatric patients with IBD. Thiopurine exposure is an important precedent event for the development of malignancy or HLH in pediatric patients with IBD.

Abstract
Although early treatment of Crohn’s disease (CD) patients with anti-tumor necrosis factor (TNF) agents or immunomodulators (IMs) may improve long-term outcomes, especially those with poor prognostic factors, their effectiveness in Asians remains unclear. In this study, Korean patients with CD naïve to both intestinal surgery and intestinal complications, and with at least two risk factors for progression (diagnosis at age <40 years, systemic corticosteroid treatment <3 months after diagnosis, and perianal fistula at diagnosis) were retrospectively analyzed. Patients were classified into those who started anti-TNFs, or IMs but not anti-TNFs, within 2 years of diagnosis, and those who started anti-TNFs and/or IMs later. Their probabilities of intestinal surgery and intestinal complications were compared. A total of 670 patients were enrolled, 79 in the early anti-TNF, 286 in the early IM, and 305 in the late treatment group. Kaplan-Meier analysis with the log-rank test showed that from starting anti-TNFs/IMs, times to intestinal surgery (P < 0.001), stricturing complications (P = 0.002), and penetrating complications (P < 0.001) were significantly longer in the early anti-TNF/IM groups than in the late treatment group. Multivariate Cox regression analysis showed that, from starting anti-TNFs/IMs, late anti-TNF/IM treatment was independently associated with higher risks of intestinal surgery (adjusted hazard ratio [aHR] 2.321, 95% confidence interval [CI] 1.503–3.584, P < 0.001), behavioral progression (aHR 2.001, 95% CI 1.449–2.763, P < 0.001), stricturing complications (aHR 1.736, 95% CI 1.209–2.493, P = 0.003), and penetrating complications (aHR 3.315, 95% CI 2.094–5.249, P < 0.001) than early treatment. In conclusion, treatment of Asian CD patients having poor prognostic factors with anti-TNFs/IMs within 2 years of diagnosis is associated with better clinical outcomes than later treatment.

Abstract
Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract, with increasing incidence worldwide. Crohn's disease might result from a complex interplay between genetic susceptibility, environmental factors, and altered gut microbiota, leading to dysregulated innate and adaptive immune responses. The typical clinical scenario is a young patient presenting with abdominal pain, chronic diarrhoea, weight loss, and fatigue. Assessment of disease extent and of prognostic factors for complications is paramount to guide therapeutic decisions. Current strategies aim for deep and long-lasting remission, with the goal of preventing complications, such as surgery, and blocking disease progression. Central to these strategies is the introduction of early immunosuppression or combination therapy with biologicals in high-risk patients, combined with a tight and frequent control of inflammation, and adjustment of therapy on the basis of that assessment (treat to target strategy). The therapeutic armamentarium for Crohn's disease is expanding, and therefore the need to develop biomarkers that can predict response to therapies will become increasingly important for personalised medicine decisions in the near future. In this Seminar, we provide a physician-oriented overview of Crohn's disease in adults, ranging from epidemiology and cause to clinical diagnosis, natural history, patient stratification and clinical management, and ending with an overview of emerging therapies and future directions for research.

Abstract
Crohn's disease is one of the major subtypes of idiopathic inflammatory bowel disease and is characterized by chronic transmural intestinal inflammation of the gastrointestinal tract anywhere from mouth to the anus, with a predilection for the small bowel. Cross-sectional imaging with computed tomography and magnetic resonance enterography plays a key role in confirming diagnosis, identifying and managing complications, assessing disease severity, and identifying response to medical therapy. This review will focus on the role of radiologists in the diagnosis and assessment of Crohn's disease. Additionally, a review of current medical therapy approaches, available medications, and side effects will be discussed. The review will also highlight key complications of medical therapy and associated diseases that should be evaluated by the radiologist with cross-sectional imaging.

[PMID: 28247573 DOI: 10.1111/apt.13995] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2016] [Revised: 08/01/2016] [Accepted: 01/28/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND Crohn's disease (CD) and rheumatoid arthritis are chronic, progressive and disabling conditions that frequently lead to structural tissue damage. Based on strategies originally developed for rheumatoid arthritis, the treatment goal for CD has recently moved from exclusively controlling symptoms to both clinical remission and complete mucosal healing (deep remission), with the final aim of preventing bowel damage and disability. AIM To review the similarities and differences in treatment goals between CD and rheumatoid arthritis. METHODS This review examined manuscripts from 1982 to 2016 that discussed and/or proposed therapeutic goals with their supportive evidence in CD and rheumatoid arthritis. RESULTS Proposed therapeutic strategies to improve outcomes in both rheumatoid arthritis and CD include: (i) evaluation of musculoskeletal or organ damage and disability, (ii) tight control, (iii) treat-to-target, (iv) early intervention and (v) disease modification. In contrast to rheumatoid arthritis, there is a paucity of disease-modification trials in CD. CONCLUSIONS Novel therapeutic strategies in CD based on tight control of objective signs of inflammation are expected to change disease course and patients' lives by halting progression or, ideally, preventing the occurrence of bowel damage. Most of these strategies require validation in prospective studies, whereas several disease-modification trials have addressed these issues in rheumatoid arthritis over the last decade. The recent approval of new drugs in CD such as vedolizumab and ustekinumab should facilitate initiation of disease-modification trials in CD in the near future.

Abstract
BACKGROUND Minimising placebo response is essential for drug development. AIM To conduct a meta-analysis to determine placebo response and remission rates in trials and identify the factors affecting these rates. METHODS MEDLINE, EMBASE and CENTRAL were searched from inception to April 2014 for placebo-controlled trials of pharmacological interventions for Crohn's disease. Placebo response and remission rates for induction and maintenance trials were pooled by random-effects and mixed-effects meta-regression models to evaluate effects of study-level characteristics on these rates. RESULTS In 100 studies containing 67 induction and 40 maintenance phases and 7638 participants, pooled placebo remission and response rates for induction trials were 18% [95% confidence interval (CI) 16-21%] and 28% (95% CI 24-32%), respectively. Corresponding values for maintenance trials were 32% (95% CI 25-39%) and 26% (95% CI 19-35%), respectively. For remission, trials enrolling patients with more severe disease activity, longer disease duration and more study centres were associated with lower placebo rates, whereas more study visits and longer study duration was associated with higher placebo rates. For response, findings were opposite such that trials enrolling patients with less severe disease activity and longer study duration were associated with lower placebo rates. Placebo rates varied by drug class and route of administration, with the highest placebo response rates observed for biologics. CONCLUSIONS Placebo rates vary according to whether trials are designed for induction or maintenance and the factors influencing them differ for the endpoints of remission and response. These findings have important implications for clinical trial design in Crohn's disease.

Abstract
INTRODUCTION Crohn's disease (CD) is a chronic, immune-mediated condition with a potentially disabling and destructive course. Despite growing data on when to use a therapeutic 'top-down' strategy, clinical management of this complex disorder is still challenging. Currently, the discussion of 'top-down' strategy in CD mostly includes biological therapy alone or in combination. Areas covered: This article is based on a review of existing literature regarding the use of biological therapy in a 'top-down' approach for the treatment of Crohn's disease. The authors reviewed all the major databases including MEDLINE as well as DDW and ECCO abstracts, respectively. Expert opinion: A 'top-down' therapeutic approach in Crohn's disease is strongly supported by existing data in patients with several risk factors for a severe course of disease. Moreover, there is an increasing amount of published data recommending a more individualised therapeutic strategy to identify candidates for 'top-down' treatment, based on enhanced diagnostics using biomarkers. Emerging therapeutic approaches besides existing therapy concepts using biologicals may possibly redefine the 'top-down' therapeutic strategy for Crohn's disease in the future.

Abstract
Strategies for management of inflammatory bowel diseases are shifting from simple control of symptoms toward full control of these diseases (clinical and endoscopic remission), with the final aim of blocking their progression and preventing bowel damage and disability. New goals have been proposed for treatment, such as treat to target and tight control based on therapeutic monitoring and early intervention. For patients who achieve clinical remission, there is often interest in discontinuation of therapy due to safety or economic concerns. We review the evidence supporting these emerging paradigms, the reasons that early effective treatment can alter progression of inflammatory bowel diseases, the importance of examining objective signs of inflammation, and the safety of reducing treatment dosage. We also discuss recent findings regarding personalization of care, including factors that predict patient outcomes and response to therapies, as well as preventative strategies.

Abstract
Crohn's disease (CD) is a chronic, progressive, and disabling disease that leads in most cases to the development of bowel damage presenting as a fistula, abscess, or stricture. For years, therapy for Crohn's disease has been based on a "step-up" approach, in which anti-TNF agents are administered after the failure of steroids and immunosuppressants. However, recent studies have suggested that early introduction of anti-TNF agents combined with immunosuppressants can modify the natural history of the disease. Patients who could benefit more of this "top-down" strategy would be those at elevated risk of a complicated or severe inflammatory bowel disease or with factors that can predict an aggressive disease course. Therefore, the management of a patient with CD should be personalized, taking into account the patient's specific characteristics and comorbidities, disease activity, site and behavior of the disease, and predictable factors of poor prognosis. A balance between medication and potential adverse effects should be achieved, trying to avoid under or overtreatment, always discussing the different therapeutic options with the patient. The natural history of ulcerative colitis differs from CD and, to date, there is not much scientific evidence on the use of early combined immunosuppression.

Abstract
INTRODUCTION Crohn's disease (CD) and ulcerative colitis (UC) have a progressive course leading to hospitalisation and surgery. The ability of existing therapies to alter disease course is not clearly defined. AIM To investigate the comparative efficacy of currently available inflammatory bowel disease (IBD) therapies to reduce hospitalisation and surgery. METHODS We conducted a systematic review in MEDLINE/PubMed for randomised controlled trials (RCT) published between January 1980 and May 2016 examining efficacy of biological or immunomodulator therapy in IBD. We performed direct comparisons of pooled proportions of hospitalisation and surgery. Pair-wise comparisons using a random-effects Bayesian network meta-analysis were performed to assess comparative efficacy of different treatments. RESULTS We identified seven randomised controlled trials (5 CD; 2 UC) comparing three biologics and one immunomodulator with placebo. In CD, anti-TNF biologics significantly reduced hospitalisation [Odds ratio (OR) 0.46, 95% confidence interval (CI) 0.36-0.60] and surgery (OR 0.23, 95% CI 0.13-0.42) compared to placebo. No statistically significant reduction was noted with azathioprine or vedolizumab. Azathioprine was inferior to both infliximab and adalimumab in preventing CD-related hospitalisation (>97.5% probability). Anti-TNF biologics significantly reduced hospitalisation (OR 0.48, 95% CI 0.29-0.80) and surgery (OR 0.67, 95% CI 0.46-0.97) in UC. There were no statistically significant differences in the pair-wise comparisons between active treatments. CONCLUSIONS In CD and UC, anti-TNF biologics are efficacious in reducing the odds of hospitalisation by half and surgery by 33-77%. Azathioprine and vedolizumab were not associated with a similar improvement, but robust conclusions may be limited due to paucity of RCTs.

Abstract
Investigator-initiated randomized clinical trials are the backbone of academic clinical research. Investigator-initiated trials (IITs) complement the large clinical studies sponsored by industry and address questions, which are usually not the main focus of a commercially directed research but have the purpose to confirm, improve, or refute clinically important questions with regard to diagnostic and therapeutic approaches in patient care. The aim of this review is to illustrate the necessary steps to start and complete an IIT in the field of inflammatory bowel diseases in the United States. The initial milestones for an investigator include structuring a protocol, planning and building of the trial infrastructure, accurately estimating the costs of the trial, and gauging the time span for recruitment. Once the trial has begun it is important to keep patient recruitment on target, monitor of the data quality, and document treatment emergent adverse events. This article provides a framework for the different phases of an IIT and outlines potential hurdles, which could hinder a successful execution.

Abstract
The use of thiopurines in inflammatory bowel disease (IBD) has been examined in numerous prospective, controlled trials, with a majority demonstrating a clinical benefit. We conducted this review to describe the historical and current evidence in the use of thiopurines in IBD. A systematic search was performed on MEDLINE between 1965 and 2016 to identify studies on thiopurines in IBD. The most robust evidence for thiopurines in IBD includes induction of remission in combination with anti-tumor necrosis factor (anti-TNF) agents, and maintenance of remission and post-operative maintenance in Crohn’s disease. Less evidence exists for thiopurine monotherapy in induction of remission, maintenance of ulcerative colitis, chemoprevention of colorectal cancer, and in preventing immunogenicity to anti-TNF. Evidence was often limited by trial design. Overall, thiopurines have demonstrated efficacy in a broad range of presentations of IBD. With more efficacious novel therapeutic agents, the positioning of thiopurines in the management of IBD will change and future studies will analyze the benefit of thiopurines alone and in conjunction with these new medications.

Abstract
BACKGROUND Treating inflammatory bowel diseases (IBD) using thiopurines is effective; however, a high rate of adverse effects and lack of efficacy limit its use. Retrospective studies have suggested that treatment with low-dose thiopurines in combination with allopurinol is associated with higher remission rates and lower incidence of adverse events. AIM To compare the rates of clinical remission and the rates of adverse events in IBD patients treated with either standard treatment with azathioprine or low-dose azathioprine in combination with allopurinol. METHODS A prospective, open-label study, randomizing thiopurine-naïve IBD patients with normal thiopurine methyltransferase to 24 weeks of treatment with either standard azathioprine dose or low-dose azathioprine and allopurinol. RESULTS A total of 46 patients with ulcerative colitis or Crohn's disease were randomized. We conducted an intention to treat analysis and found a significant (69.6%) proportion of the patients treated with low-dose azathioprine in combination with allopurinol was in clinical remission without the need for steroid or biologic treatment at week 24 compared to 34.7% of the patients treated with azathioprine monotherapy (RR, 2.10 [95% CI: 1.07-4.11]). In the azathioprine group, 47.8% of the patients compared to 30.4% of the patients in the azathioprine-allopurinol group had to withdraw from the study due to adverse events (RR, 1.47 [95% CI: 0.76-2.85]) Conclusions: This study indicated that by changing the treatment strategy from standard weight-based dosing of azathioprine to weight-based low-dose azathioprine in combination with allopurinol, we can increase remission rates in patients with IBD.

Abstract
Improving the efficacy and reducing the toxicity of thiopurines and methotrexate (MTX) have been areas of intense basic and clinical research. An increased knowledge on pharmacodynamics and pharmacokinetics of these immunomodulators has optimized treatment strategies in inflammatory bowel disease (IBD). This review focuses on the metabolism and mode of action of thiopurines and MTX, and provides an updated overview of individualized treatment strategies in which efficacy in IBD can be increased without compromising safety. The patient-based monitoring instruments adapted into clinical practice include pretreatment thiopurine S-methyltransferase testing, thiopurine metabolite monitoring, and blood count measurements that may help guiding the dosage to improve clinical outcome. Other approaches for optimizing thiopurine therapy in IBD include combination therapy with allopurinol, 5-aminosalicylates, and/or biologics. Similar strategies are yet to be proven effective in improving the outcome of MTX therapy. Important challenges for the management of IBD in the future relate to individualized dosing of immunomodulators for maximal efficacy with minimal risk of side effects. As low-cost conventional immunomodulators still remain a mainstay in pharmacotherapy of IBD, more research remains warranted, especially to substantiate these tailored management strategies in controlled clinical trials.
