Abstract
PURPOSE This unselected, population-based cohort study aimed to determine the level of health-related quality of life (HRQoL) in patients with Crohn's disease (CD) and ulcerative colitis (UC) at the time of diagnosis compared with a reference population and identify the demographic factors, psychosocial measures, and disease activity markers associated with HRQoL. METHODS Adult patients newly diagnosed with CD or UC were prospectively enrolled. HRQoL was measured using the Short Form 36 (SF-36) and Norwegian Inflammatory Bowel Disease Questionnaires. Clinical significance was assessed using Cohen's d effect size and further compared with a Norwegian reference population. Associations between HRQoL and symptom scores, demographic factors, psychosocial measures, and disease activity markers were analyzed. RESULTS Compared with the Norwegian reference population, patients with CD and UC reported significantly lower scores in all SF-36 dimensions, except for physical functioning. Cohen's d effect sizes for men and women in all SF-36 dimensions were at least moderate, except for bodily pain and emotional role for men with UC and physical functioning for both sexes and diagnoses. In the multivariate regression analysis, depression subscale scores ≥ 8 on the Hospital Anxiety and Depression Scale, substantial fatigue, and high symptom scores were associated with reduced HRQoL. CONCLUSION Patients newly diagnosed with CD and UC reported statistically and clinically significantly lower scores in seven of the eight SF-36 dimensions than the reference population. Symptoms of depression, fatigue, and elevated symptom scores were associated with poorer HRQoL.

Abstract
Background Patients with Crohn's disease (CD) are most often diagnosed as young adults; therefore, long-term studies are needed to assess the risk of cancer over their lifetime. Thus, the aims of the present study were to determine the risk of cancer in a Norwegian population-based cohort (the Inflammatory Bowel South Eastern Norway [IBSEN] study), 30 years after diagnosis, and to assess whether patients with CD were at an increased risk of specific cancer types. Methods The IBSEN cohort prospectively included all incident patients diagnosed between 1990 and 1993. Data on cancer incidence were obtained from the Cancer Registry of Norway. Overall and cancer-specific hazard ratios (HRs) for CD patients compared with age- and sex-matched controls were modeled using Cox regression. Standardized incidence ratios (SIRs) were estimated compared to the general population. Results In total, the cohort included 237 patients with CD, and 36 of them were diagnosed with cancer. Compared to the general Norwegian population, patients with CD had an increased overall risk of cancer (HR = 1.56, 95% CI: 1.06-2.28), particularly male patients (HR = 1.85, 95% CI: 1.08-3.16). The incidence of lung cancer and nonmelanoma skin cancer was increased; however, the difference was not statistically significant (SIR = 2.29, 95% CI: 0.92-4.27 and SIR = 2.45, 95% CI: 0.67-5.37, respectively). Conclusions After 30 years of follow-up, the risk of all cancers in patients with CD was increased compared to the general population.

Abstract
OBJECTIVES Patients with ulcerative colitis (UC) have shown an increased risk for colorectal cancer, hepatobiliary, hematologic, and skin cancers, but updated long-term data is needed. This study aimed to estimate the risk of cancer in patients with UC compared to the general Norwegian population, in a population-based cohort (the IBSEN study), 30 years after diagnosis; and to identify possible risk factors associated with cancer. METHODS The IBSEN cohort prospectively included all incident patients between 1990 and 1993. Cancer incidence data were obtained from the Cancer Registry of Norway. The overall and cancer-specific hazard ratios (HR) were modelled using Cox regression. Standardized incidence ratios were estimated compared to the general population. RESULTS In total, the cohort included 519 patients, and 83 cases were diagnosed with cancer. There was no statistically significant difference in the overall cancer risk (HR = 1.01, 95% CI: [0.79-1.29]) and colorectal cancer risk (HR = 1.37, 95% CI: [0.75-2.47]) between patients and controls. The incidence of biliary tract cancer was higher than expected (SIR = 9.84, 95%CI: [3.19-20.15]), especially when UC patients suffered from primary sclerosing cholangitis. Male UC patients were also more at risk of being diagnosed with hematologic malignancies (HR = 3.48, 95% CI: [1.55-7.82]). Being prescribed thiopurines was associated with a higher risk of cancer (HR = 2.03, 95% CI: [1.02-4.01]). CONCLUSIONS At 30 years after diagnosis, the risk of all cancer in patients with UC was not significantly increased compared with the general population. However, the risks of biliary tract cancer and hematologic cancers were increased, particularly in male patients.

Abstract
Crohn's disease (CD) is a chronic inflammatory disorder characterized by a transmural inflammation that may involve any part of the gastrointestinal tract. An evaluation of small bowel involvement, allowing recognition of disease extent and severity, is important for disease management. Current guidelines recommend the use of capsule endoscopy (CE) as a first-line diagnosis method for suspected small bowel CD. CE has an essential role in monitoring disease activity in established CD patients, as it can assess response to treatment and identify high-risk patients for disease exacerbation and post-operative relapse. Moreover, several studies have shown that CE is the best tool to assess mucosal healing as part of the treat-to-target strategy in CD patients. The PillCam Crohn's capsule is a novel pan-enteric capsule which enables visualization of the whole gastrointestinal tract. It is useful to monitor pan-enteric disease activity, mucosal healing and accordingly allows for the prediction of relapse and response using a single procedure. In addition, the integration of artificial intelligence algorithms has showed improved accuracy rates for automatic ulcer detection and the ability to shorten reading times. In this review, we summarize the main indications and virtue for using CE for the evaluation of CD, as well as its implementation in clinical practice.

Abstract
Capsule endoscopy (CE) has proven to be a valuable diagnostic modality for small bowel diseases over the past 20 years, particularly Crohn's disease (CD), which can affect the entire gastrointestinal tract from the mouth to the anus. CE is not only used for the diagnosis of patients with suspected small bowel CD, but can also be used to assess disease activity, treat-to-target, and postoperative recurrence in patients with established small bowel CD. As CE can detect even mildly non-specific small bowel lesions, a high diagnostic yield is not necessarily indicative of high diagnostic accuracy. Moreover, the cost effectiveness of CE as a third diagnostic test employed usually after ileocolonoscopy and MR or CT enterography is an important consideration. Recently, new developments in colon capsule endoscopy (CCE) have increased the utility of CE in patients with ulcerative colitis (UC) and pan-enteric CD. Although deflation of the colon during the examination and the inability to evaluate dysplasia-associated lesion or mass results in an inherent risk of overestimation or underestimation, the convenience of CCE examination and the risk of flare-up after colonoscopy suggest that CCE could be used more actively in patients with UC.

Abstract
BACKGROUND AND AIM Modern treatment strategies for inflammatory bowel disease (IBD) are postulated to change the natural disease course. Inception cohort studies are the gold standard for investigating such changes. We have initiated a new population-based inception cohort study; Inflammatory bowel disease in South Eastern Norway III (IBSEN III). In this article, we describe the study protocol and baseline characteristics of the cohort. METHODS IBSEN III is an ongoing, population-based observational inception cohort study with prospective follow-up. Adult and pediatric patients with suspected IBD in the South-Eastern Health Region of Norway (catchment area of 2.95 million inhabitants in 2017), during the 3-year period from 2017 to 2019, were eligible for inclusion. Comprehensive clinical, biochemical, endoscopic, demographic, and patient-reported data were collected at the time of diagnosis and throughout standardized follow-up. For a portion of the patients, extensive biological material was biobanked. RESULTS The study included 2168 patients, of whom 1779 were diagnosed with IBD (Crohn's disease: 626, ulcerative colitis: 1082, IBD unclassified: 71). In 124 patients, there were subtle findings indicative of, but not diagnostic for, IBD. The remaining 265 patients were classified as symptomatic non-IBD controls. CONCLUSION We have included patients in a comprehensive population-based IBD cohort from a catchment population of 2.95 million, and a unique biobank with materials from newly diagnosed and treatment-naïve IBD patients and symptomatic non-IBD controls. We believe this cohort will add important knowledge about IBD in the years to come.

Abstract
PURPOSE Subtotal colectomy (STC) is performed for severe acute and refractory colitis. The diagnosis can be difficult even after the surgery when colectomy specimen has overlapping features of ulcerative colitis (UC) and Crohn's disease (CD). The aim of this study was to evaluate the rate of postoperative diagnostic revision to CD after surgery and determine predictor factors. METHODS Retrospective study of 110 patients who underwent STC (2005-2018). RESULTS Preoperative diagnosis comprised UC = 80 (73%), CD = 11 (10%), and unclassified colitis (IBDU = 19, 17%). Initial diagnosis of IBDU and UC was modified to CD in 6 patients (6%) after STC. The final diagnosis after the follow-up of 10 ± 6 years switched from CD for 8 patients (9%). The multivariate analysis showed that patients with a colitis evolving for less than 10 years and initial diagnosis of IBDU were the two independent factors associated with an increased risk of diagnosis change to CD (p = 0.03; p = 0.016). At the end of the follow-up, 15 patients (14%) had a definitive stoma. CONCLUSIONS In patients with IBD, attention must be paid to determine the right restorative strategy to patients with an evolution of the disease less than 10 years or with IBDU who are more at risk to have a diagnosis change to CD after STC.

Abstract
BACKGROUND The differential diagnosis of inflammatory bowel diseases (IBDs) between Crohn's disease (CD) and ulcerative colitis (UC) is important for designing an effective therapeutic regimen. However, without any adequate gold standard method for differential diagnosis currently, therapeutic design remains a major challenge in clinical practice. In this context, recent studies have showed that circulating leptin stands out as a potential biomarker for the categorization of IBDs. Thus, we aimed to summarize the current understanding of the prognostic and diagnostic value of serum leptin in patients with IBDs. METHODS A systematic search was performed in PubMed/MEDLINE, Scopus, Cochrane Library, and Web of Science databases. Articles that aimed to study the relationship between circulating levels of leptin and IBDs were included. Finally, the meta-analysis was performed with the mean serum leptin levels in patients with IBDs and healthy controls using RevMan 5.3 software, with I2 > 50% as a criterion for substantial heterogeneity. RESULTS Nineteen studies were included. Serum leptin levels among patients with IBDs and healthy controls did not show a significant difference (95% CI, -2.15 to 0.57; I2, 86%, P ≤ 0.00001). Similarly, there was no association of leptin levels with the activity of IBDs (95% CI, -0.24 to 0.06; I2, 50%; P = 0.13). However, serum leptin levels were significantly higher in patients with CD than those in patients with UC (95% CI, -2.09 to -0.37; I2, 7%; P ≤ 0.36). CONCLUSION This review suggested that serum leptin levels might be a promising biomarker to help in the differentiation between CD and UC.

Abstract
BACKGROUND AND AIMS The long-term course of ulcerative colitis [UC] is difficult to predict. Mortality, colectomy, cancer, and hospitalisation represent hard outcomes of disease. Moreover, knowledge on the risk of relapses and need for potent medication add important information about living with UC. We aimed to evaluate the course and prognosis of UC during the first 20 years after diagnosis, and to identify early prognostic risk factors. METHODS From 1990 to 1994, a population-based inception cohort of patients with inflammatory bowel disease was enrolled in South-Eastern Norway. A systematic follow-up [FU] was conducted at 1,5, 10, and 20 years after diagnosis. Clinical outcomes were recorded continuously, and possible relationships between early disease characteristics and outcomes were analysed using multiple regression analysis. RESULTS Among 519 UC patients, 119 died, 60 were lost to FU, and 340 were included in the FU cohort. The 20-year cumulative risk of colectomy was 13.0% (95% confidence interval [CI] [11.4-14.6]). Extensive colitis at diagnosis was independently associated with an increased risk of colectomy compared with proctitis (hazard ratio [HR] = 2].8, 95% CI [1.3-6.1]). In contrast, mucosal healing at 1-year FU was independently associated with reduced risk of colectomy [HR = 0.4, 95% CI [0.2-0.8]), and inversely associated with subsequent risk of relapse [adjusted HR = 0.5, 95% CI [0.3-0.7]). CONCLUSIONS The overall risk of colectomy in our cohort was lower than expected from previous studies, although considerable for patients with extensive colitis at diagnosis. Early mucosal healing was associated with better disease outcomes 20 years after diagnosis.

Abstract
Ulcerative colitis and Crohn’s disease are the main entities of inflammatory bowel disease characterized by chronic remittent inflammation of the gastrointestinal tract. The incidence and prevalence are on the rise worldwide, and the heterogeneity between patients and within individuals over time is striking. The progressive advance in our understanding of the etiopathogenesis coupled with an unprecedented increase in therapeutic options have changed the management towards evidence-based interventions by clinicians with patients. This guideline was stimulated and supported by the Emirates Gastroenterology and Hepatology Society following a systematic review and a Delphi consensus process that provided evidence- and expert opinion-based recommendations. Comprehensive up-to-date guidance is provided regarding diagnosis, evaluation of disease severity, appropriate and timely use of different investigations, choice of appropriate therapy for induction and remission phase according to disease severity, and management of main complications.

Abstract
Our aim in this study was to analyze the importance of childbearing for risk of inflammatory bowel disease. Using data from the Norwegian Population Register and the Norwegian Patient Register, we fitted discrete-time hazard models for diagnosis of Crohn disease (CD) or ulcerative colitis (UC) among men and women aged 18-81 years in 2011-2016. Year and various sociodemographic factors were controlled for. The data included 4,304 CD cases and 8,866 UC cases. Women whose youngest child was ≤4 years of age had lower CD risk the following year than childless women (odds ratio (OR) = 0.73, 95% confidence interval (CI): 0.62, 0.86). There was no such reduction in CD risk among fathers. Men whose youngest child was aged ≥20 years had higher risks of CD (OR = 1.22, 95% CI: 1.01, 1.49) and UC (OR = 1.15, 95% CI: 1.02, 1.30) than childless men. UC risk was also increased among men whose youngest child was aged ≤4 years (OR = 1.14, 95% CI: 1.02, 1.27). The short-term reduction in women's CD risk after a birth may reflect biological effects of pregnancy. Alternatively, it may reflect residual confounding or lifestyle effects of parenthood that are of special relevance for CD in women. In particular, differences in use of oral contraceptives (which it was not possible to control for) may have contributed to the observed pattern.

Abstract
Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

Abstract
BACKGROUND AND AIM Little is known regarding the exact burden of inflammatory bowel disease (IBD) in Asian countries because previous epidemiologic studies were hospital based. We aimed to develop and validate an operational definition of IBD cases from health insurance claims data and to examine the epidemiological features of IBD in Korea. METHODS We analyzed stratified sample data from the Korean Health Insurance Review and Assessment (2010-2016) database using 12 different definitions and applied the best definition to the entire (2007-2016) dataset. RESULTS The definition that combined the International Classification of Disease 10th revision code with IBD-specific medications had the best performance characteristics among the 12 tested definitions. During the 8-year study period, IBD prevalence increased from 25 345 in 2009 to 47 444 in 2016. Over that period, the prevalence of Crohn's disease increased 1.9-fold (from 16.0/100 000 in 2009 to 29.6/100 000 in 2016) and that of ulcerative colitis increased 1.6-fold (from 41.4/100 000 in 2009 to 66.0/100 000 in 2016). Similarly, the estimated incidence of Crohn's disease also increased 1.2-fold (from 2.4 to 2.9 per 100 000) and that of ulcerative colitis rose 1.3-fold (from 4.0 to 5.3 per 100 000). During the study period, the predominant increase in IBD incidence was among younger individuals, especially those aged < 30 years. CONCLUSION Patients with IBD can be accurately identified using Korean insurance claims data by combining information regarding the International Classification of Disease 10th revision codes and the IBD medications used. The prevalence of IBD continues to increase, with an apparent shift toward younger (< 30 years) age groups.

Abstract
Up to 25% of inflammatory bowel disease (IBD) presents during childhood, often with severe and extensive disease, leading to significant morbidity including delayed growth and nutritional impairment. The classical approach to management has centred on differentiation into Crohn's disease (CD) or ulcerative colitis (UC), with subsequent treatment based on symptoms, results and complications. However, IBD is a heterogeneous condition with substantial variation in phenotype, disease course and outcome, so whilst effective treatment exists one size does not fit all. The ability to predict disease course at diagnosis, alongside tailoring medications based on response gives the potential for a more 'personalised approach'. The move to a pre-emptive strategy to prevent IBD-related complications, whilst simultaneously minimising side effects and long-term toxicity from therapy, particularly in those with relatively indolent disease, has the potential to revolutionise care. In very early-onset IBD, personalised approaches to diagnosis and management have become the standard of treatment enabling clinicians to significantly alter the outcomes of the few children with monogenic disease. However, the promise of discoveries in genomics, microbiome and transcriptomics in paediatric IBD has not yet translated to clinical application for the vast majority of patients. Despite this, the opportunity presents itself to apply data gathered at diagnosis and follow-up to predict which patients are likely to progress to complicated disease, which will respond well and which will require additional therapy. Using complex mathematics and innovative, cutting-edge machine learning (ML) techniques gives the potential to use this data to develop personalised clinical care algorithms to treat patients more effectively, reduce toxicity and improve outcome. In this review, we will consider current management of paediatric IBD, discuss how precision medicine is making inroads into clinical practice already, examine the contemporary studies applying data to stratify patients and explore how future management may be revolutionised by personalisation with clinical, genomic and other multi-omic data.

Abstract
BACKGROUND/AIMS Accurately diagnosing inflammatory bowel disease (IBD) remains a challenge, but is crucial for providing proper management for affected patients. The aim of the present study was to evaluate the frequency of change in diagnosis in Korean patients who were referred to our institution with a diagnosis of IBD. METHODS We enrolled 1,444 patients diagnosed with ulcerative colitis (UC) and 1,452 diagnosed with Crohn's disease (CD), who had been referred to the Asan Medical Center between January 2010 and December 2014. These patients were assessed and subsequently classified as having UC, CD, indeterminate colitis, possible IBD, or non-IBD. RESULTS During a median follow-up of 15.9 months, 400 of the 2,896 patients (13.8%) analyzed in this study experienced a change in diagnosis. A change in diagnosis from UC to CD, or vice-versa, was made in 24 of 1,444 patients (1.7%) and 23 of 1,452 patients (1.6%), respectively. A change to a non-IBD diagnosis was the most common modification; 7.5% (108 of 1444) and 12.7% (184 of 1452) of the patients with a referral diagnosis of UC and CD, respectively, were reclassified as having non-IBD. Among the 292 patients who were ultimately determined not to have IBD, 135 (55 UC and 80 CD cases) had received IBD-related medication. CONCLUSIONS There are diagnostic uncertainties and difficulties in relation to IBD. Therefore, precise assessment and systematic follow-up are essential in the management of this condition.

Abstract
OBJECTIVES Identifying ulcerative colitis (UC) patients with increased risk of colectomy is essential for appropriate treatment. We aimed to develop a prediction model assessing the risk of having colectomy within the first 10 years after diagnosis. MATERIAL AND METHODS A population-based inception cohort of UC patients diagnosed in south-eastern Norway between 1990 and 1994 has been followed for 10 years. Altogether 519 patients were recruited including 49 patients who were colectomized. Based on the best-fitted multivariate model, the probabilities of colectomy were computed for selected levels of baseline covariates, and the results arranged in a prediction matrix. The following risk factors at diagnosis were analyzed: age, smoking, sex, disease extent, weight loss and fever and need for systemic steroids. Biochemical markers included C-reactive protein (CRP, <30 or ≥30 mg/l); erythrocyte sedimentation rate (ESR, <30 or ≥30 mm/h) and hemoglobin (Hgb, <10.5 or ≥ 10.5 g/dL). RESULTS Extent of disease, age (<40 years, ≥40 years), need for systemic steroids and CRP or ESR (<30 or ≥30) at diagnosis were independently associated with colectomy and were combined in a prediction matrix. The probabilities of colectomy during the follow-up period ranged from 2.6% to 40.1% depending on the combination of predictors at diagnosis. CONCLUSIONS Our prediction model revealed significant differences in the probability of undergoing colectomy during a 10-years course of disease, which supports an early individualized treatment approach in UC.

Nonbloody Diarrhea but Not Significant Weight Loss at Diagnosis Is Associated with the Development of Denovo Crohn's Disease After Ileal Pouch-anal Anastomosis for Ulcerative Colitis. Inflamm Bowel Dis 2016; 22:654-61.

Abstract
BACKGROUND Denovo Crohn's disease (CD) develops in 5% to 10% of patients after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) leading to increased morbidity and rates of pouch failure. Initial nonbloody diarrhea and weight loss at diagnosis are independent risk factors for a change in diagnosis from UC to CD in nonsurgical patients. We investigated whether these features were risk factors for denovo CD in a longitudinal cohort of patients with UC undergoing IPAA. METHODS Prospective profiles of patients with UC undergoing IPAA followed over a 22-year period by 1 surgeon were analyzed. Denovo CD was diagnosed when mucosal inflammation (5 or more ulcers) involved the small bowel mucosa proximal to the ileal pouch any time after surgery and/or when a pouch fistula or other perianal complication developed more than 3 months after ileostomy closure. Patients with inflammatory bowel disease unclassified, acute pouchitis, chronic pouchitis, and those lost to follow-up were excluded from analysis. Cox regression analysis was performed for statistical significance. RESULTS Of the 199 study patients included in the analysis, denovo CD developed in 42 patients (21%). Patients who developed denovo CD had an increased incidence of nonbloody diarrhea (n = 12; 29%) compared with patients who had no evidence of pouch inflammation (n = 25; 16%) (P = 0.03). In contrast, the incidence of weight loss was not significantly increased in patients with denovo CD (n = 7; 17%) compared with patients who never had pouch inflammation (n = 16; 10%) (P = 0.12). CONCLUSIONS Initial nonbloody diarrhea is associated with denovo CD after IPAA. This association warrants close consideration before surgery.

Abstract
BACKGROUND Crohn's disease and ulcerative colitis are the two major forms of inflammatory bowel disease; treatment strategies have historically been determined by this binary categorisation. Genetic studies have identified 163 susceptibility loci for inflammatory bowel disease, mostly shared between Crohn's disease and ulcerative colitis. We undertook the largest genotype association study, to date, in widely used clinical subphenotypes of inflammatory bowel disease with the goal of further understanding the biological relations between diseases. METHODS This study included patients from 49 centres in 16 countries in Europe, North America, and Australasia. We applied the Montreal classification system of inflammatory bowel disease subphenotypes to 34,819 patients (19,713 with Crohn's disease, 14,683 with ulcerative colitis) genotyped on the Immunochip array. We tested for genotype-phenotype associations across 156,154 genetic variants. We generated genetic risk scores by combining information from all known inflammatory bowel disease associations to summarise the total load of genetic risk for a particular phenotype. We used these risk scores to test the hypothesis that colonic Crohn's disease, ileal Crohn's disease, and ulcerative colitis are all genetically distinct from each other, and to attempt to identify patients with a mismatch between clinical diagnosis and genetic risk profile. FINDINGS After quality control, the primary analysis included 29,838 patients (16,902 with Crohn's disease, 12,597 with ulcerative colitis). Three loci (NOD2, MHC, and MST1 3p21) were associated with subphenotypes of inflammatory bowel disease, mainly disease location (essentially fixed over time; median follow-up of 10·5 years). Little or no genetic association with disease behaviour (which changed dramatically over time) remained after conditioning on disease location and age at onset. The genetic risk score representing all known risk alleles for inflammatory bowel disease showed strong association with disease subphenotype (p=1·65 × 10(-78)), even after exclusion of NOD2, MHC, and 3p21 (p=9·23 × 10(-18)). Predictive models based on the genetic risk score strongly distinguished colonic from ileal Crohn's disease. Our genetic risk score could also identify a small number of patients with discrepant genetic risk profiles who were significantly more likely to have a revised diagnosis after follow-up (p=6·8 × 10(-4)). INTERPRETATION Our data support a continuum of disorders within inflammatory bowel disease, much better explained by three groups (ileal Crohn's disease, colonic Crohn's disease, and ulcerative colitis) than by Crohn's disease and ulcerative colitis as currently defined. Disease location is an intrinsic aspect of a patient's disease, in part genetically determined, and the major driver to changes in disease behaviour over time.

Sparse Modeling Reveals miRNA Signatures for Diagnostics of Inflammatory Bowel Disease. PLoS One 2015; 10:e0140155.

Abstract
The diagnosis of inflammatory bowel disease (IBD) still remains a clinical challenge and the most accurate diagnostic procedure is a combination of clinical tests including invasive endoscopy. In this study we evaluated whether systematic miRNA expression profiling, in conjunction with machine learning techniques, is suitable as a non-invasive test for the major IBD phenotypes (Crohn's disease (CD) and ulcerative colitis (UC)). Based on microarray technology, expression levels of 863 miRNAs were determined for whole blood samples from 40 CD and 36 UC patients and compared to data from 38 healthy controls (HC). To further discriminate between disease-specific and general inflammation we included miRNA expression data from other inflammatory diseases (inflammation controls (IC): 24 chronic obstructive pulmonary disease (COPD), 23 multiple sclerosis, 38 pancreatitis and 45 sarcoidosis cases) as well as 70 healthy controls from previous studies. Classification problems considering 2, 3 or 4 groups were solved using different types of penalized support vector machines (SVMs). The resulting models were assessed regarding sparsity and performance and a subset was selected for further investigation. Measured by the area under the ROC curve (AUC) the corresponding median holdout-validated accuracy was estimated as ranging from 0.75 to 1.00 (including IC) and 0.89 to 0.98 (excluding IC), respectively. In combination, the corresponding models provide tools for the distinction of CD and UC as well as CD, UC and HC with expected classification error rates of 3.1 and 3.3%, respectively. These results were obtained by incorporating not more than 16 distinct miRNAs. Validated target genes of these miRNAs have been previously described as being related to IBD. For others we observed significant enrichment for IBD susceptibility loci identified in earlier GWAS. These results suggest that the proposed miRNA signature is of relevance for the etiology of IBD. Its diagnostic value, however, should be further evaluated in large, independent, clinically well characterized cohorts.

Abstract
OBJECTIVE Coexistence of ANCA-associated vasculitis (AAV) and IBD is a rare condition that is rarely described in the literature. The aim of the study was to describe the main characteristics of patients presenting with both IBD and AAV. METHODS A retrospective study of AAV patients in the French Vasculitis Study Group cohort who also had a diagnosis of IBD was conducted. We reviewed the medical records and outcomes of these patients. RESULTS We identified 11 patients with AAV and IBD. Four patients with eosinophilic granulomatosis with polyangiitis (Churg-Strauss) also had ulcerative colitis and seven patients with granulomatosis with polyangiitis (GPA) had Crohn's disease. No Crohn's disease was observed in eosinophilic GPA and no ulcerative colitis in GPA. IBD started before AAV manifestations in six cases, simultaneously in two cases and after AAV manifestations in three cases. CONCLUSION Coexistence of IBD and AAV is a rare condition. The therapeutic management of these patients includes corticosteroids in all cases and immunosuppressive drugs in some patients. Coexistence of IBD and AAV might be explained by common underlying inflammatory responses and cytokine profiles polarized towards either Th1 or Th2. Finally, in the presence of digestive manifestations in the context of AAV, the hypothesis of IBD should be assessed.

Abstract
Scandinavian researchers have contributed to the present understanding of inflammatory bowel disease (IBD). Important epidemiological data and family risk factors have been reported from all the Nordic countries, original twin studies mainly from Denmark and Sweden, and relationships to cancer and surgery mostly from Sweden. In collaboration with the industry, development of medical compounds was for a long time in the front line of international research, and the Scandinavian countries participated in the clinical breakthrough of biologic treatment. At present, many Nordic centers are working in the forefront of IBD research. An increasing number of young investigators have entered the scene along with the extended distribution of University clinics and research laboratories in these countries. This presentation of IBD gives a brief overview in the fields of clinical epidemiology and molecular biology. Many areas are covered by International collaborations with partners from Nordic centers. IBD was a topic focused by the founders of Scandinavian Journal of Gastroenterology. After 50 years one may state that the journal's history reflects important pieces of scientific knowledge within these diseases. The early scope of Johannes Myren for IBD was shown through his work in the original World Association of Gastroenterology (OMG), and after 50 years we can clearly support the view that global perspectives in IBD are increasingly important.

Abstract
BACKGROUND There is an urgent need for cheap, reproducible, easy to perform and specific biomarkers for diagnosis, differentiation and stratification of inflammatory bowel disease (IBD) patients. Technical advances allow for the determination of volatile organic compounds in the human breath to differentiate between health and disease. AIM Review and discuss medical literature on volatile organic compounds in exhaled human breath in GI disorders, focusing on diagnosis and differentiation of IBD. METHODS A systematic search in PubMed, Ovid Medline and Scopus was completed using appropriate keywords. In addition, a bibliography search of each article was performed. RESULTS Mean breath pentane, ethane, propane, 1-octene, 3-methylhexane, 1-decene and NO levels were elevated (P < 0.05 to P < 10(-7)) and mean breath 1-nonene, (E)-2-nonene, hydrogen sulphide and methane were decreased in IBD compared to healthy controls (P = 0.003 to P < 0.001). A combined panel of 3 volatile organic compounds (octene, (E)-2-nonene and decene) showed the best discrimination between paediatric IBD and controls (AUC 0.96). Breath condensate cytokines were higher in IBD compared to healthy individuals (P < 0.008). Breath pentane, ethane, propane, isoprene and NO levels correlated with disease activity in IBD patients. Breath condensate interleukin-1β showed an inverse relation with clinical disease activity. CONCLUSIONS Breath analysis in IBD is a promising approach that is not yet ready for routine clinical use, but data from other gastrointestinal diseases suggest the feasibility for use of this technology in clinical practice. Well-designed future trials, incorporating the latest breath detection techniques, need to determine the exact breath metabolome pattern linked to diagnosis and phenotype of IBD.

Abstract
BACKGROUND & AIMS To improve the clinical course of ulcerative colitis (UC), more accurate serum diagnostic and assessment methods are required. We used serum metabolomics to develop diagnostic and assessment methods for UC. METHODS Sera from UC patients, Crohn's disease (CD) patients, and healthy volunteers (HV) were collected at multiple institutions. The UC and HV were randomly allocated to the training or validation set, and their serum metabolites were analyzed by gas chromatography mass spectrometry (GC/MS). Using the training set, diagnostic and assessment models for UC were established by multiple logistic regression analysis. Then, the models were assessed using the validation set. Additionally, to establish a diagnostic model for discriminating UC from CD, the CD patients' data were used. RESULTS The diagnostic model for discriminating UC from HV demonstrated an AUC of 0.988, 93.33% sensitivity, and 95.00% specificity in the training set and 95.00% sensitivity and 98.33% specificity in the validation set. Another model for discriminating UC from CD exhibited an AUC of 0.965, 85.00% sensitivity, and 97.44% specificity in the training set and 83.33% sensitivity in the validation set. The model for assessing UC showed an AUC of 0.967, 84.62% sensitivity, and 88.23% specificity in the training set and 84.62% sensitivity, 91.18% specificity, and a significant correlation with the clinical activity index (rs=0.7371, P<0.0001) in the validation set. CONCLUSIONS Our models demonstrated high performance and might lead to the development of a novel treatment selection method based on UC condition.

Abstract
GOALS AND BACKGROUND Inflammatory bowel disease (IBD) serology testing is often used in patients with indeterminate colitis (IC) to help distinguish between ulcerative colitis (UC) and Crohn's disease (CD). We investigated the performance of serology testing in predicting future diagnosis in this setting. STUDY This was an observational study of individuals with IC at a single center who underwent IBD serology testing [anti-Saccharomyces cerevisiae antibody (ASCA), perinuclear anti-neutrophil cytoplasmic antibody (pANCA), and anti-outer membrane porin C antibody (anti-OmpC)] and had at least 12 months follow-up from the time of serology test results. RESULTS A total of 117 individuals with IC and with 1-year follow-up data were enrolled. All IC patients had endoscopic and histologic evidence of colitis at enrollment. One year after serology testing, 58 (50%) individuals with IC were diagnosed with UC, 49 (42%) with CD, and 10 (9%) remained labeled with IC. The sensitivity/specificity of an initial positive pANCA for a subsequent diagnosis of UC was 78%/44%. For ASCA and anti-OmpC, the results were 18%/84% and 27%/75%, respectively, for a subsequent diagnosis of CD. A positive pANCA test was associated with a likelihood ratio (LR) of 1.4 [95% confidence interval (CI), 1.1-1.8] for a subsequent diagnosis of UC at 1 year. Neither positive ASCA (LR 1.1; 95% CI, 0.5-2.5) nor anti-OmpC (LR 1.1; 95% CI, 0.6-2.0) was associated with a subsequent diagnosis of CD in patients with IC. CONCLUSIONS The disease phenotype in the majority of individuals initially labeled with IC evolved to be more consistent with either UC or CD on follow-up. pANCA, ASCA, and anti-OmpC, individually, were of limited utility in predicting a patient's subsequent disease phenotype.

Abstract
BACKGROUND In Japan, Crohn's disease (CD) is diagnosed according to a single, well-established set of diagnostic criteria. However, no nationwide attempt has been made to determine which specific criteria within these diagnostic criteria are used to make diagnoses. METHODS A questionnaire-based survey was conducted of patients given a definitive or suspected diagnosis of CD before January 2011 according to the Japanese Diagnostic Criteria for Crohn's Disease. The survey included 579 patients with a definitive diagnosis of CD and 59 patients with a suspected diagnosis of CD at 34 Japanese medical institutions. RESULTS A total of 87.4 % of definitive diagnoses of CD were based on the criterion in the definite category: major finding A "longitudinal ulcer (LU)" or B "cobblestone-like appearance (CSA)". A total of 30.4 % of definitive diagnoses were based on the criterion: major finding C "non-caseating epithelioid cell granuloma (NCEG)" with minor finding a "irregularshaped and/or quasi-circular ulcers or aphthous ulcerations found extensively in the gastrointestinal tract" or b "characteristic perianal lesions". Finally, 7.1 % of definitive diagnoses were made according to the criterion: all minor findings a, b and c "characteristic gastric and/or duodenal lesions". Among suspected diagnoses of CD, 74.6 % were based on the criterion in the suspected category: one or two minor findings. CONCLUSIONS The Japanese diagnostic criteria for Crohn's disease consist of combinations of specific morphological findings. Many of the diagnoses were based on the findings of LU or CSA.

Abstract
BACKGROUND The point prevalence estimates of anaemia in patients with inflammatory bowel disease (IBD) range between 6% and 74%. The variation is probably due to differences in the definition of anaemia and the study populations. AIM To retrospectively determine the prevalence of anaemia at diagnosis and at the 1-, 5- and 10-year follow-ups in patients with IBD from a prospectively followed, population-based inception cohort (the IBSEN Study). To compare the prevalence of anaemia after a 10-year disease course with the prevalence of anaemia in the background population, and to assess clinical factors associated with anaemia at diagnosis and during follow-up. METHODS Newly diagnosed IBD patients were included in a population-based, prospective cohort. Follow-up was performed at 1, 5 and 10 years. All visits included clinical examinations and blood samples. Anaemia was defined according to the WHO. RESULTS A total of 756 patients (UC, n = 519 and CD, n = 237) were included; 48.8% of CD and 20.2% of UC patients were anaemic at diagnosis (P < 0.001). The proportion of patients with anaemia decreased during the disease course in all patients, except in women with CD. After 10 years of disease, the relative risk for anaemia was increased in all groups, except for women with UC. The variables associated with anaemia were generally unchanged during the disease course, and elevated CRP was the strongest predictor of risk. CONCLUSIONS Anaemia was more common in CD than in UC. The prevalence of anaemia decreased during the disease course. Women with CD were at high risk for anaemia. Elevated CRP was independently associated with anaemia.

Abstract
BACKGROUND Identifying patients with Crohn's disease with increased risk of subsequent complications is essential for appropriate treatment. Based on exploratory analysis, we developed a prediction model for assessing the probability of developing advanced disease 5 and 10 years after diagnosis. METHODS A population-based cohort of 237 patients with Crohn's disease diagnosed from 1990-1994 was followed for 10 years. In the 5-year analysis, advanced disease was defined as having intestinal resection, progression in disease behavior, or need for thiopurines. The analysis was limited to patients with uncomplicated disease at diagnosis who were alive (n = 140), excluding those who were lost during follow-up (n = 8). For the 10-year analysis, advanced disease was defined as having surgery, excluding those who had surgery within the first 30 days (n = 7), those who died (n = 18), or were lost during follow-up (n = 22). Based on the best fitted multiple model, the probabilities of advanced disease were computed for selected baseline levels of the covariates and the results were arranged in a prediction matrix. Except for ASCA, all predictors were measured at diagnosis. RESULTS ASCA status, disease location, age, and need for systemic steroids were included in the 5-year prediction matrix. The probabilities of advanced disease during this period varied from 8.6% to 92.0% depending on the combination of predictors. The 10-year matrix combined ASCA status, disease behavior, age, and need for systemic steroids; the probabilities of advanced disease ranged from 12.4% to 96.7%. CONCLUSIONS Our prediction models revealed substantial differences in the probability of developing advanced disease in the short and intermediate course of Crohn's disease, suggesting that a model-based prediction matrix is useful in early disease management.

Abstract
The histologic examination of endoscopic biopsies or resection specimens remains a key step in the work-up of affected inflammatory bowel disease (IBD) patients and can be used for diagnosis and differential diagnosis, particularly in the differentiation of UC from CD and other non-IBD related colitides. The introduction of new treatment strategies in inflammatory bowel disease (IBD) interfering with the patients' immune system may result in mucosal healing, making the pathologists aware of the impact of treatment upon diagnostic features. The European Crohn's and Colitis Organisation (ECCO) and the European Society of Pathology (ESP) jointly elaborated a consensus to establish standards for histopathology diagnosis in IBD. The consensus endeavors to address: (i) procedures required for a proper diagnosis, (ii) features which can be used for the analysis of endoscopic biopsies, (iii) features which can be used for the analysis of surgical samples, (iv) criteria for diagnosis and differential diagnosis, and (v) special situations including those inherent to therapy. Questions that were addressed include: how many features should be present for a firm diagnosis? What is the role of histology in patient management, including search for dysplasia? Which features if any, can be used for assessment of disease activity? The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas.

Abstract
BACKGROUND Ulcerative colitis (UC) negatively affects health-related quality of life (HRQoL), but population-based and long-term data on this topic are scarce. Our aim was to determine the HRQoL in UC patients after a 10-year disease duration. METHODS UC patients from a population-based inception cohort met at a prescheduled 10-year follow-up visit. In addition to a clinical examination, interview, and blood samples, the patients completed the Short Form 36 (SF-36) and the Norwegian Inflammatory Bowel Disease Questionnaire (N-IBDQ). The SF-36 scores were compared to scores from a general population sample using one-sample t-tests. Standardized scores were calculated and interpreted according to Cohen's effect size index. The associations between relevant clinical and demographic factors and HRQoL were examined through linear regression analyses. RESULTS A total of 196 patients completed the HRQoL questionnaires (response rate: 80%), of whom 54% were women; the mean age of all patients was 48 years (range: 22-86). The SF-36 scores were comparable to those of the general population except for lower scores in the General Health dimension. The SF-36 scores were significantly lower in the presence of current symptoms, in patients who had used corticosteroids, and in patients who reported not working. Overall N-IBDQ scores were equivalent to scores of patients in remission. Female gender, work status (not working), current symptoms, and smoking were associated with significantly lower N-IBDQ scores. CONCLUSIONS SF-36 scores were not reduced compared to the general population sample. The presence of current symptoms, the use of corticosteroids, work status (not working), female gender, and smoking had a negative impact on HRQoL.

Abstract
The diagnosis of inflammatory bowel disease (IBD) is traditionally based on a combination of clinical, endoscopic, histological, and radiological criteria. However, further testing is needed in cases of diagnostic uncertainty and in predicting disease course. This systematic review focuses on the potential for 10 serological antibodies to fill these roles: pANCA, ASCA, anti-OmpC, anti-CBir1, anti-I2, ALCA, ACCA, AMCA, anti-L, and anti-C. We discuss their prevalence in IBD and health; their role in disease diagnosis and risk stratification; their stability over time; their presence in unaffected relatives; their association with genetic variants; and differences across ethnic groups. Serological antibodies have some role in primary diagnosis and in differentiating between Crohn's disease and ulcerative colitis. In indeterminate colitis, preoperative measurement of serological antibodies can help to predict the likelihood of complications among patients undergoing pouch surgery. The combined presence and magnitude of a large panel of antibodies appear to be of value in predicting disease progression. There is currently insufficient evidence to recommend the use of antibody testing to predict responses to treatment or surgery in patients with IBD.

Abstract
BACKGROUND AND AIMS The use of complementary and alternative medicine (CAM) has been increasing in recent decades. Our aim was to determine the proportion of CAM use among patients with inflammatory bowel disease (IBD) in a longitudinal, population-based cohort and to identify predictive factors for CAM use. METHODS The Inflammatory Bowel South-Eastern Norway (IBSEN) study is a population-based IBD cohort that has been followed prospectively for 10 years. The ten-year follow-up was conducted from 2000 to 2004 and included a questionnaire regarding CAM, a structured interview, a review of hospital records, a clinical examination, laboratory tests, and an ileocolonoscopy. RESULTS Of the 620 patients evaluated at the ten-year follow-up, 517 (84%) completed the CAM questionnaire, 353 had ulcerative colitis (UC), 164 had Crohn's disease (CD), and 50% were male. Thirty percent reported the use of CAM at some point since their IBD diagnosis, and 7.5% reported current CAM use. More CD patients than UC patients reported CAM use (38% vs. 27%, respectively; p=0.01). Younger age, female gender, and higher education level predicted CAM use in UC, whereas younger age was the only predictor of CAM use in CD. Thirty-six percent of the CAM users were mostly satisfied or very satisfied with the treatment. CONCLUSION One third of the patients in this population-based cohort had used CAM at some point during a ten-year disease course, but only 7.5% reported current CAM use. CAM use was more common in the CD than in the UC patients. Only socio-demographic factors, such as age, gender and education, predicted CAM use.

Abstract
BACKGROUND The incidence of inflammatory bowel disease (IBD) is high in Western countries, but during the last decade the figures have stabilized, or only slightly increased; at the same time, an increasing incidence rate has been observed in Eastern Europe and Asia. The purpose of this study was to estimate the incidence of IBD in Finland between 2000 and 2007. METHODS New IBD cases between 2000-2007 were retrieved from the national database of special reimbursements for drugs costs. The register includes virtually all Finnish IBD patients since 1986. The incidence rates were calculated per 100,000 persons assuming a Poisson distribution. RESULTS In total, 14,214 IBD patients were identified; 10,352 had ulcerative colitis (UC) and 3,862 had Crohn's disease (CD). During the whole study period the mean annual incidence of IBD per 100,000 was 34.0: in CD 9.2 and in UC 24.8. The incidence of UC was notably higher in males (27.8) than in females (21.9). In CD the incidence rates did not differ significantly between genders. The incidence of UC increased from 22.1 in 2000-2001 to 27.4 in 2006-2007. The incidence of CD increased only slightly. CONCLUSION In Finland, the incidence of IBD is high, and UC is almost three times more common than CD. During the new millennium the incidence rate of UC has increased, while the incidence rate of CD has remained fairly stable. To the best of our knowledge, the incidence of UC in this nationwide register study is one of the highest reported to date.

Abstract
OBJECTIVE The present population based adult cohort was part of a new prospective study of patients with inflammatory bowel disease (IBD) in South-Eastern Norway, the Inflammatory Bowel South-Eastern Norway II study, investigating disease characteristics in an attempt to improve our knowledge regarding factors related to early clinical phenotype and disease activity. MATERIAL AND METHODS Patients suspected to have IBD on the basis of predefined symptoms, including abdominal pain, diarrhea, and/or blood in stool for more than 10 days were examined at the local hospital. Colonoscopy with biopsies was performed and blood and stool samples were taken. RESULTS In ulcerative colitis (UC) patients, the median Simple Clinical Colitis Activity Index (SCCAI) was 4 (range 0-10) in mild and 6 (range 0-14) in patients with moderate or severe endoscopic activity of inflammation (p = 0.002). The calprotectin concentration in feces was significantly related to the SCCAI (p = 0.034) and the Mayo endoscopic subscore (p = 0.031). There was a significant association between the C-reactive protein (CRP) value, leucocytes and thrombocytes and the SCCAI, but only leucocytes were significantly associated with the Mayo endoscopic subscore. In Crohn's disease (CD) patients, there was no statistical significant association between the Harvey-Bradshaw Index (HBI) and the endoscopic grade of mucosal inflammation (p = 0.8). The calprotectin concentration in feces was significantly related to the endoscopic activity score (p = 0.004), but not to the HBI (p = 0.5). HBI was significantly related to the CRP value (p = 0.047) and thrombocytes (p = 0.03). CONCLUSIONS In UC, both biochemical and fecal markers are related to disease activity and extent of disease, whereas in CD, the fecal calprotectin concentration is a reliable marker of mucosal affection, but not for systemic disease activity.

Abstract
In the West, the incidence and prevalence of inflammatory bowel diseases has increased in the past 50 years, up to 8-14/100,000 and 120-200/100,000 persons, respectively, for ulcerative colitis (UC) and 6-15/100,000 and 50-200/100,000 persons, respectively, for Crohn's disease (CD). Studies of migrant populations and populations of developing countries demonstrated a recent, slow increase in the incidence of UC, whereas that of CD remained low, but CD incidence eventually increased to the level of UC. CD and UC are incurable; they begin in young adulthood and continue throughout life. The anatomic evolution of CD has been determined from studies of postoperative recurrence; CD begins with aphthous ulcers that develop into strictures or fistulas. Lesions usually arise in a single digestive segment; this site tends to be stable over time. Strictures and fistulas are more frequent in patients with ileal disease, whereas Crohn's colitis remains uncomplicated for many years. Among patients with CD, intestinal surgery is required for as many as 80% and a permanent stoma required in more than 10%. In patients with UC, the lesions usually remain superficial and extend proximally; colectomy is required for 10%-30% of patients. Prognosis is difficult to determine. The mortality of patients with UC is not greater than that of the population, but patients with CD have greater mortality than the population. It has been proposed that only aggressive therapeutic approaches, based on treatment of early recurrent lesions in asymptomatic individuals, have a significant impact on progression of these chronic diseases.

Abstract
PURPOSE Resources for studying inflammatory bowel disease (IBD) are needed in evaluations of drug safety including traditional drugs and new biologics agents. We developed an IBD registry, with ascertainment from computerized visit information. OBJECTIVE We sought to characterize the positive predictive value (PPV) of IBD case-finding using computerized data compared with chart review. METHODS We identified 2906 persons aged 89 years or younger with one or more IBD diagnoses in computerized visit data during the period of 1996-2002. The diagnosis of IBD was confirmed through chart review. Adopting chart review as the gold standard, the validity of computerized encounter data to determine IBD was estimated. RESULTS Among the 2906 study subjects with one or more ICD-9 diagnosis codes of 555 or 556 in computerized data, 81% were confirmed as having IBD by chart review. Defining cases as those who underwent two or more visits without regard to diagnostic procedures or drug utilization maximized the correct classification of cases (PPV, 95%). CONCLUSIONS The quality of IBD diagnoses in computerized data is adequate to meet the aims of a wide range of research studies.

Abstract
Genome-wide association studies (GWAS) have been applied to various gastrointestinal and liver diseases in recent years. A large number of susceptibility genes and key biological pathways in disease development have been identified. So far, studies in inflammatory bowel diseases, and in particular Crohn’s disease, have been especially successful in defining new susceptibility loci using the GWAS design. The identification of associations related to autophagy as well as several genes involved in immunological response will be important to future research on Crohn’s disease. In this review, key methodological aspects of GWAS, the importance of proper cohort collection, genotyping issues and statistical methods are summarized. Ways of addressing the shortcomings of the GWAS design, when it comes to rare variants, are also discussed. For each of the relevant conditions, findings from the various GWAS are summarized with a focus on the affected biological systems.

Abstract
Our understanding of inflammatory bowel disease (IBD), treatment options, complications and their management has expanded significantly over the past few decades. When caring for patients it is important to remember the complexities of pathogenesis and pharmacology. This review is to identify errors in diagnosis, treatment, complications and preventive care issues that arise while caring for patients with IBD and to provide recommendations and information that can be shared with patients and their health care providers. A review of the literature was undertaken using MEDLINE from 1981 to present. We included randomized controlled studies, case-control studies, and review articles. There are many associated conditions and complications recognized in patients with IBD and current treatment strategies do result in many side effects, some are serious and some are not widely recognized. With the advent of anti-TNF therapies and the newer 5-amino salicylate derivatives, options available have increased significantly. It is also important to remember that these patients are followed by more than one health care provider and it is important for all involved to communicate the plan of action.

Abstract
The first gene associated with Crohn disease (CD) has been identified as CARD15 (16q12). Three variants, R702W, G908R and 1007fsinsC are strongly and independently associated with the disease. A second gene, conveying a smaller risk for inflammatory bowel disease (IBD), has been identified as DLG5 (10q23). We assess the frequency of the CARD15 SNPs and of the R30Q mutation in DLG5 and their contribution to the development of CD in a cohort of unrelated IBD patients (151 CD, 325 ulcerative colitis (UC)) and healthy controls (236) from South-east Norway (IBSEN cohort). Genotype-based tests of population differentiation using 23 SNPs across CARD15, together with estimates of F(ST), indicated that the German and Norwegian background populations could be differentiated at the CARD15 locus. The Norwegian and German CD samples exhibited particularly strong differentiation at the three predisposing loci and those marking their background haplotype. There were significantly lower frequencies of the CARD15 SNPs and no significant association with CD in the Norwegian samples. Only a marginal association was observed for the subphenotypes ileitis and ileocolitis vs colitis (P=0.048). The population attributable risk percentage (PAR%) for CARD15 variants in the Norwegian cohort is the lowest reported for a European population (1.88%), except Iceland. Similarly, the DLG5 variant showed no association with CD or IBD, however, there was a negative correlation with stricture (P=0.035). The present results are consistent with an emerging pattern of a low frequency of the CARD15 variants in Northern countries where the prevalence of IBD is greatest.

Abstract
OBJECTIVE Cohort studies of unselected and newly diagnosed patients are essential for a better understanding of the prognosis in ulcerative colitis (UC). The aim of this study was to evaluate the course of UC in a population-based inception cohort during the first 10 years, and to identify prognostic risk factors based on information gathered at diagnosis. MATERIAL AND METHODS From 1990 to 1994, a population-based cohort of 843 patients with inflammatory bowel disease was enrolled in South-Eastern Norway. The cohort was systematically followed-up at 1, 5 and 10 years after diagnosis. RESULTS Of 519 patients with UC, 423 completed the 10-year follow-up, 53 died and 43 were lost to follow-up. The mortality risk was not increased compared with that in the general population. The cumulative colectomy rate after 10 years was 9.8% (95% CI: 7.4-12.4%). Initial presentation with extensive colitis and erythrocyte sedimentation rate (ESR) > or =30 mm/h was associated with an increased hazard ratio (HR) (3.57, 95% CI: 1.60-7.96) and age > or =50 years at diagnosis, with reduced HR (0.28, 95% CI: 0.12-0.65) for subsequent colectomy. Relapsing disease was noted in 83%, but half (48%) of the patients were relapse free during the last 5 years. One-fifth (69/288) of patients with proctitis or left-sided colitis had progressed to extensive colitis. CONCLUSIONS The prognosis for UC during the first 10 years was generally good. The colectomy rate was low, and a large proportion of patients were in remission as time progressed. Patients with initially extensive colitis and elevated ESR could benefit from an early potent medical treatment strategy.

Abstract
Inflammatory bowel diseases such as Crohn disease and ulcerative colitis are frequently clinical conditions in children. Another clinical entity, indeterminate colitis, is considered a subgroup of pediatric inflammatory bowel disease. It is generally characterized by early onset in the first years of life, and clinical behavior is rapidly progressive to pancolitis. The definition of indeterminate colitis has changed over the years, but it is usually used to identify severe colitis with overlapping features of ulcerative colitis and Crohn disease. Ileal pouch-anal anastomosis is the surgical treatment of choice for patients with ulcerative colitis, but increased rates of complications have been found in indeterminate colitis. Therefore, it is better to be cautious in patients with indeterminate colitis who present with severe attacks and require surgery.

Abstract
Inflammatory bowel diseases (IBD) are a heterogeneous group of diseases, not always easy to diagnose, even more difficult to classify, and diagnostic criteria are not always uniform. Well done population-based studies are not abundant, and so comparisons among different geographical areas or populations are not always very reliable. In this article, we have reviewed epidemiological studies available on the world’s population while making a critical review of published data.

Abstract
BACKGROUND & AIMS Most studies concerning the clinical course in CD are retrospective or based on selected patient groups. Our aim was to assess the course of CD in a prospective population-based follow-up study and to identify possible prognostic risk factors for complications on the basis of information obtained at initial diagnosis. METHODS From 1990-1994, a population-based cohort of 843 new cases of inflammatory bowel disease was recruited in South-Eastern Norway. The cohort was systematically followed up at 1, 5, and 10 years after diagnosis. RESULTS Of 237 patients classified as CD, 197 completed the 10 years of follow-up, 18 died, and 22 were lost to follow-up. The cumulative relapse rate during the first 10 years was 90% (95% confidence interval, 86%-94%), and the cumulative probability of surgery was 37.9% (95% confidence interval, 31.4%-44.4%). Terminal ileal location (P < .001), stricturing (P = .004), penetrating behavior (P < .001), and age younger than 40 years (P = .03) at diagnosis were independent risk factors for subsequent surgery. A total of 53% (n = 105) of the patients had developed stricturing or penetrating disease at 10 years. A large proportion of patients (44%) were in clinical remission during the last 5 years of follow-up. CONCLUSIONS The prognosis for CD seems better than previously reported. The probability of surgery was low, and fewer than expected developed complicated disease behavior. Nevertheless, the cumulative relapse rate of 90% and the finding of prognostic risk factors for subsequent surgery might call for attention to early effective medical treatment strategies.

Abstract
BACKGROUND AND AIM The use of infliximab in the treatment of Crohn's disease (CD) is acceptable and appears to be effective in ulcerative colitis (UC). Careful patient selection, resulting in infliximab only for truly refractory inflammatory bowel disease (IBD), may improve its efficacy. The present study aimed to determine if careful patient selection improved infliximab efficacy in IBD. METHODS CD or UC/IBD unclassified patients (Montreal classification) were considered for infliximab treatment only after failure of disease control with conventional therapies and confirmation of active disease. Patients with purely luminal IBD received a single infliximab dose. Patients with fistulizing disease (with or without luminal disease) received infliximab at 0, 2 and 6 weeks. Changes to Harvey Bradshaw (HBI) for inflammatory CD and Colitis Activity Index (CAI) for UC/IBDU were used to determine the response and remission rates. In fistulizing CD, a remission was sustained cessation of drainage and resolution of the fistula. Response was correlated to inflammatory marker levels. RESULTS Seventy IBD patients were treated. In CD, 85.2% (46/54) had active luminal and 40.7% (22/54) had fistulizing disease. In luminal CD, at 8 weeks a single infliximab dose induced remission in 75% (24/32) of patients compared to 92.9% (13/14) after infliximab at 0, 2 and 6 weeks. Fistulizing disease responded in 77.2% (17/22) and remitted in 50% (11/22) of patients at 8 weeks. In UC/IBDU, 75% (12/16) responded and 43.8% (7/16) of patients were in remission at 8 weeks. CONCLUSION Careful patient selection may improve infliximab's efficacy and clinical remission appears greater after induction with three infliximab doses in CD. Clinical efficacy is suggested for UC/IBDU.
