Abstract
INTRODUCTION Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease, characterized by painful and recurrent lesions in apocrine gland-bearing skin areas. It is a heterogeneous disease, which makes assessment and data collection difficult. Questionnaires with detailed items, such as the Belgian European Registry for Hidradenitis Suppurativa (ERHS-Be), are useful to study HS and its associated comorbidities. The aim of this registry was to uncover new factors associated with HS and understand HS patients' clinical profiles and efficacy of treatments. MATERIAL AND METHODS The ERHS-Be registry is based on questionnaires, with sections for sociodemographic data, medical and HS history, clinical examination, and treatment plan. It allows identification of different clinical phenotypes and automatic calculation of severity scores. RESULTS At present, 606 patients are included in the ERHS-Be (67% women, 33% men). The mean age at the first visit is 38.5 years. Tobacco use is present in 72.6% of patients. A family history of HS is noted in 42% of patients. Comorbidities are documented in this cohort: depression is present in 43.8% of patients, arthritis in 27.8%, obesity in 31.5%, hypertension in 10.6%, diabetes mellitus in 6.4%, and dyslipidemia in 12.4%. Moreover, 7.7% of patients suffer from IBD and 27.4% have a pilonidal sinus. History of severe acne is found in 32.1% of patients and psoriasis in 9.3%. Thirteen percent of women in our cohort suffer from polycystic ovarian syndrome. Severity of disease is quantified in 533 patients: for instance, Hurley I, II, and III scores proportions are, respectively, 32.3%, 52.7%, and 15%, while the mean IHS4 score is 5.2. This registry also enables determination of relative phenotype proportions in our cohort, according to different classifications. CONCLUSION The ERHS-Be questionnaires allow systematic and larger data collection, including detailed comorbidities, phenotypes, and severity of disease. Analysis of this large database will contribute to a better understanding and management of HS, at a time where new therapeutic options are becoming available.

Correlation of Socioeconomic and Environmental Factors With Incidence of Crohn Disease in Children and Adolescents: Systematic Review and Meta-Regression. JMIR Public Health Surveill 2024; 10:e48682. [PMID: 38526534 PMCID: PMC11002755 DOI: 10.2196/48682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 12/28/2023] [Accepted: 01/23/2024] [Indexed: 03/26/2024] Open
Abstract
BACKGROUND The worldwide incidence of Crohn disease (CD) in childhood and adolescence has an increasing trend, with significant differences between different geographic regions and individual countries. This includes an increase in the incidence of CD in countries and geographic regions where CD was not previously prevalent. In response to the increasing incidence, the pediatric care landscape is facing growing challenges. OBJECTIVE This systematic review and meta-analysis were undertaken to comprehensively delineate the incidence rates of CD in pediatric populations across different countries and to explore potential influencing factors. METHODS We performed a systematic review of PubMed and Embase (via Ovid) for studies from January 1, 1970, to December 31, 2019. In addition, a manual search was performed in relevant and previously published reviews. The results were evaluated quantitatively. For this purpose, random effects meta-analyses and meta-regressions were performed to investigate the overall incidence rate and possible factors influencing the incidence. RESULTS A qualitative synthesis of 74 studies was performed, with 72 studies included in the meta-analyses and 52 in the meta-regressions. The results of our meta-analysis showed significant heterogeneity between the individual studies, which cannot be explained by a sample effect alone. Our findings showed geographical differences in incidence rates, which increased with increasing distance from the equator, although no global temporal trend was apparent. The meta-regression analysis also identified geographic location, UV index, and Human Development Index as significant moderators associated with CD incidence. CONCLUSIONS Our results suggest that pediatric CD incidence has increased in many countries since 1970 but varies widely with geographic location, which may pose challenges to the respective health care systems. We identified geographic, environmental, and socioeconomic factors that contribute to the observed heterogeneity in incidence rates. These results can serve as a basis for future research. To this end, implementations of internationally standardized and interoperable registries combined with the dissemination of health data through federated networks based on a common data model, such as the Observational Medical Outcomes Partnership, would be beneficial. This would deepen the understanding of CD and promote evidence-based approaches to preventive and interventional strategies as well as inform public health policies aimed at addressing the increasing burden of CD in children and adolescents.

Abstract
Recent advances in our understanding of the pathogenesis of inflammatory bowel disease (IBD) have highlighted the complex interplay between the genome, the epigenome, and the environment. Despite the exciting advances in genomics that have enabled the identification of over 200 susceptibility loci, these only account for a small proportion of the disease variance and the estimated heritability in IBD. It is likely that gene-environment (GxE) interactions contribute to "missing heritability" and these may act through epigenetic mechanisms. Several environmental factors, such as the microbiome, nutrition, and tobacco smoking, induce alterations in the epigenome of children and adults, which may impact disease susceptibility. Other mechanisms for GxE interactions are also directly pertinent in early life. We discuss a model in which environmental factors imprint disease risk in a window of susceptibility during infancy that may contribute to later disease onset, whereas other elements of the exposome act later in life and contribute directly to the pathogenesis and course of the disease. Understanding the mechanisms underlying GxE interactions may provide the basis for new therapeutic targets or preventative strategies for IBD.

BMC Gastroenterol 2023; 23:199. [PMID: 37291531 DOI: 10.1186/s12876-023-02840-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 05/31/2023] [Indexed: 06/10/2023] Open
Abstract
BACKGROUND Birth cohort studies with linked register-based data on inflammatory bowel disease (IBD) provide opportunities to prospectively study early-life determinants of the disease. However, register-based data often lack information on clinical characteristics and rely on diagnostic algorithms. Within the All Babies in Southeast Sweden (ABIS) cohort, we examined the validity of a register-based definition of IBD, its incidence, and clinical and therapeutic characteristics at diagnosis. METHODS We followed 16,223 children from birth (1997-1999) until the end of 2020 for the diagnosis of IBD as defined by a minimum of two diagnostic codes for IBD in the Swedish National Patient Register (NPR). We described the incidence and cumulative incidence of IBD. Through a medical record review of cases diagnosed by the end of 2017, we examined the positive predictive value (PPV) for IBD and described its clinical characteristics and treatment. RESULTS By 2020, at an average age of 22.2 years, 113 participants (0.74%, 95% confidence interval [CI] = 0.61-0.89) had a register-based diagnosis of IBD, corresponding to an incidence of 31.3 per 100,000 person-years of follow-up; the incidence for Crohn's disease (CD) was 11.1 per 100,000 person-years and 15.8 for ulcerative colitis (UC). Of 77 participants with a register-based definition of IBD by the end of 2017, medical records were identified for 61 participants, of whom 57 had true IBD (PPV = 93%; 95%CI = 0.87-1.00). While oral 5-aminosalicylic acid treatment was equally common in newly diagnosed CD and UC patients, biologics were more often used for newly diagnosed CD. The median faecal calprotectin levels were 1206 mg/kg at diagnosis and 93 mg/kg at the last follow-up (P < 0.001). CONCLUSIONS In this population-based sample of Swedish children and young adults the cumulative IBD incidence was 0.74. The validity of register-based definition of IBD was high and supports using such data to identify IBD patients in cohort studies.

Abstract
BACKGROUND Incidence rates of inflammatory bowel disease [IBD] reported from developed countries are rising, with some levelling out. The aim of this study was to assess the disease burden of IBD by estimating the incidence and prevalence across age groups and projecting these to 2030 in a high-incidence country. METHODS Using an algorithm [incorporating ICD codes, medications and histopathology], patients [n = 69 862] diagnosed with Crohn's disease [CD] or ulcerative colitis [UC] between 1980 and 2017 were identified in the Danish National Patient Registry and included in a nationwide cohort. RESULTS From 1980 to 2017 the overall incidence of CD increased from 5.1 [95% CI: 4.5-5.8] to 15.6 [95% CI: 14.6-16.6] per 100 000, while the incidence of UC increased from 6.2 [95% CI: 5.5-6.9] to 27.2 [95% CI: 25.9-28.6] per 100 000. For paediatric-onset CD [pCD], the incidence increased from 1.9 [95% CI: 1.2-2.8] to 9.9 [95% CI: 8.1-11.8] per 100 000 and from 1.8 [95% CI: 1.2-2.8] to 8.7 [95% CI: 7.1- 10.5] per 100 000 for paediatric-onset UC [pUC]. In 2017, the prevalence of CD and UC was 293 [95% CI: 288-297] and 523 [95% CI: 517-528] per 100 000. For pCD and pUC, the prevalence was 35 [95% CI: 31-38] and 28 [95% CI: 26-32] per 100 000. CONCLUSIONS The incidence of paediatric- and adult-onset IBD in Denmark continues to increase and is among the highest in the world.

Has the Incidence of Inflammatory Bowel Disease Peaked? Evidence From the Population-Based NorDIBD Cohort 1978-2020. Am J Gastroenterol 2023; 118:501-510.

Abstract
INTRODUCTION While the incidence of inflammatory bowel disease (IBD) is rising globally, it has been suggested to stabilize in westernized countries, but this has not yet been shown in exhaustive and large cohorts. We generated an IBD cohort in North Denmark (NorDIBD) of 6,158 patients with IBD diagnosed from 1978 to 2020, based on all recorded and verified IBD diagnoses in the region. While describing the establishment of this cohort, we aimed to present the accurate incidence and prevalence of IBD over 4 decades. METHODS The NorDIBD cohort covered all pediatric and adult patients with an IBD diagnosis dated between January 1, 1978, and December 31, 2020, and living in North Denmark, hence forming an unselected population-based patient cohort. IBD incidence rates between 1978 and 2020 and IBD point prevalences between 2003 and 2020 were calculated. RESULTS We observed a 4-fold increase in the incidence of IBD from 11.5 per 100,000 persons (95% confidence interval [CI] 8.4-14.6) in the year 1978 to 51.3/100,000 (95% CI 45.5-57.1) in the year 2014, whereas in 2020, this rate stabilized. The overall prevalence of IBD more than doubled from 2003 to 2020, from 424 (95% CI 407-443) in 2003 to 872 (95% CI 849-896) IBD cases per 100,000 persons in 2020. DISCUSSION Our population-based NorDIBD cohort suggests stabilizing of the incidence of IBD in Denmark, whereas the prevalence continues to rise. Because the data represent a 10% sample of the entire Danish IBD population, we believe that data can be extrapolated to the IBD population in general and used for healthcare planning.

Abstract
BACKGROUND & AIMS Shifts in epidemiological stages of inflammatory bowel disease (IBD) carry implications toward understanding IBD etiology and managing clinical care. We conducted a temporal analysis of the epidemiology of IBD between 1995 and 2016 in the Danish nationwide cohort. METHODS We used the Danish registers to obtain data on demographics and IBD-related outpatient and inpatient contacts between 1995 and 2016. IBD diagnosis was defined as having ≥2 registrations related to Crohn's disease (CD) or ulcerative colitis (UC) within a 2-year period. We estimated overall and annual incidence rates and prevalence of CD and UC standardized with respect to age and sex. RESULTS A total of 47,830 individuals met the criteria for IBD diagnosis, of which 33% were diagnosed with CD and 67% with UC. Between 1995 and 2016, the incidence rate (95% confidence interval) per 100,000 person-years rose from 9.1 (8.3-10.0) to 17.8 (16.8-19.0) for CD, and from 21.0 (19.8-22.3) to 28.4 (27.0-29.8) for UC. The highest increase in CD and UC incidence rates occurred in children and young adults, respectively. The prevalence of IBD doubled from 1995 to 2016; the greatest increase (2.5-fold) was in UC prevalence among individuals aged >40 years. During this period, the median age of the IBD population increased by 6 to 7 years. CONCLUSIONS In Denmark, the incidence and prevalence of IBD have increased during the last 2 decades. The IBD population is shifting toward an older age. These findings have implications towards understanding environmental shifts as well as preparing health care systems for an aging IBD population.

Abstract
Purpose The Danish National Patient Registry (DNPR) is recognized for providing high-quality data. However, only a few minor studies have validated inflammatory bowel disease (IBD) diagnoses in the DNPR, reporting various degrees of validity. To pave the way for large-scale studies of IBD in Denmark, we aimed to investigate the validity of IBD among >8000 patients registered in the DNPR between 2002 and 2020 in the North Denmark Region. Patients and Methods To evaluate the reliability of the diagnoses in the DNPR, we initially compared all patients registered with one IBD diagnosis during 2002–2020 to a list of already verified patients in the regional IBD database GASTROBIO. Medical records on all DNPR registered patients not on the list were manually reviewed by a gastroenterologist to verify or dismiss the IBD diagnosis. Positive predictive values (PPV) were calculated. Results Of 8040 patients with at least one IBD diagnosis in DNPR, 5263 were already confirmed cases, leaving 2777 for medical record evaluation, of whom 849 had IBD. In total, 6112 were correctly registered with IBD based on one diagnosis, and 1343 were incorrectly registered, resulting in a PPV of 0.82 (95% CI, 0.81–0.83). For patients registered with at least two diagnoses, the PPV was 0.95 (95% CI, 0.95–0.96), and with at least three diagnoses, the PPV was 0.98 (95% CI, 0.98–0.99). Results were similar for UC and CD separately. Of note, the completeness of valid cases went from 6112 to 4606 (75%; 95% CI, 74%-76%) when demanding at least two registered diagnoses and to 3320 (54%; 95% CI, 53%-56%) when demanding at least three registered diagnoses. Conclusion Reassuringly, the validity of IBD diagnoses in DNPR is high, especially for patients registered more than once. However, the reduced completeness when applying a true case definition of at least two registered diagnoses should be considered.

Abstract
The burden of inflammatory bowel disease (IBD) in Asia has been increasing over the past decades. Although patients with IBD show heterogenous phenotypes depending on the individual characteristics, no significant differences have been established in the IBD phenotypes of Western and Asian populations. However, despite the much lower incidence of IBD in Asia than in Western countries, the incidence has been rapidly increasing in Asia while remaining stable in Western countries. The incidence of ulcerative colitis (UC) showed an earlier and a more marked increase than the incidence of Crohn disease (CD), but the UC-to-CD ratio has recently decreased because of a relative increase in the incidence of CD in Asia. While CD shows a significant male predominance, UC only shows a slight male predominance. A recent study reported that the incidence of IBD in Asia showed a bimodal age distribution with increasing IBD prevalence, similar to the findings of Western studies. CD in Asian patients, especially those in East Asia, is characterized by ileocolonic involvement and perianal fistula. The frequency of extraintestinal manifestations, including primary sclerosing cholangitis, appears to be lower in Asia, but this finding should be interpreted with caution due to the transient and nonspecific nature of these manifestations. Although familial aggregation is lower in East Asia, it may also be explained by the low prevalence of IBD in Asia. Thus, more studies should focus on the differences in phenotypes in Asian IBD patients versus Western patients.

Abstract
A 44-year-old patient with known ulcerative colitis presented with abdominal pain and an abdominal mass. CT revealed cecal stranding, a mass at the left colonic flexure involving the pancreas and multiple lesions in the lungs, retroperitoneum and liver. The patient had also developed a scalp rash as well as impaired hearing. Biopsies from the abdominal mass and lungs revealed necrotic inflammation, and the clinical suspicion of malignancy could not be ruled out. After further examination, the patient was treated with high-dose steroids, which rapidly reduced the extraintestinal manifestations. Due to a persistent abscess formation at the left colonic flexure and pancreas, the patient was referred to our hospital for a total colectomy. Histology showed acute and chronic inflammation with cryptitis, indicating ulcerative colitis. Our case is a rare presentation of extensive extraintestinal disease in organs such as the lungs and liver, as well as necrotic mass formation at the colon site which mimicked malignancy.

Abstract
BACKGROUND There are currently no nationwide data on the epidemiology of inflammatory bowel diseases (IBD) in Israel. We aimed to determine the population-based epidemiological trends of IBD in the diverse Israeli population. METHODS Health-administrative data were retrieved from all 4 Israeli health maintenance organizations, insuring 98% of the population, using validated identification algorithms. National trends were determined using Joinpoint regression analysis calculating annual percent change and average annual percent change (AAPC). RESULTS By 2019, there were 46,074 patients with IBD in Israel, corresponding to a national prevalence of 519/100,000 (0.52%), of whom 54.1% had Crohn disease (CD) and 45.9% had ulcerative colitis (UC). The number of Jewish patients doubled from 18,701 in 2005 (354/100,000) to 38,950 (589/100,000) in 2018 (AAPC, +4.0%; P < 0.05), and the number of Arab patients increased 3-fold from 1096 (102.1/100,000) to 3534 (240.7/100,000; AAPC, +6.8%; P < 0.05) during the same years. However, the increase rate has gradually decelerated over time (annual percent change during 2005-2008, 2009-2014, and 2005-2018 was +6.7%, +4.2%, and +2.3%, respectively; P < 0.05). Pediatric prevalence increased from 37.4 to 52.2/100,000, with CD predominating in both Jews and Arabs. The incidence of CD remained stable (from 15.9/100,000 to 14.9/100,000) and the incidence of UC decreased (15.4/100,000 to 10.5/100,000 (AAPC, -3.2%; P < 0.001)). In contrast, pediatric incidence of CD increased from 7.3/100,000 to 8.3/100,000 (AAPC, +1.9%; P < 0.05) and that of UC increased from 2.6 to 4.4/100,000 (AAPC, +5.8%; P < 0.05). CONCLUSIONS The IBD prevalence rate in Israel is still increasing but gradually decelerating, probably due to the decreasing overall IBD incidence. Nonetheless, incidence rate in children is still increasing. Ongoing narrowing in the rates between Jews and Arabs over time may indicate shared environmental factors.

Abstract
New data suggest that incidence and prevalence of inflammatory bowel diseases [IBD] are still increasing worldwide, and approximately 0.2% of the European population suffer from IBD at the present time. Medical therapy and disease management have evolved significantly in recent decades, with an emphasis on tight objective monitoring of disease progression and a treat-to-target approach in Europe and also worldwide, aiming to prevent early bowel damage and disability. Surgery rate declined over time in Europe, with 10-30% of CD and 5-10% of UC patients requiring a surgery within 5 years. The health economic burden associated with IBD is high in Europe. Direct health care costs [approximately €3500 in CD and €2000 in UC per patient per year] have shifted from hospitalisation and surgery towards drug-related expenditures with the increasing use of biologic therapy and other novel agents, and substantial indirect costs arise from work productivity loss [approximately €1900 per patient yearly]. The aim of this paper is to provide an updated review of the burden of IBD in Europe by discussing current data on epidemiology, disease course, risk for surgery, hospitalisation, and mortality and cancer risks, as well as the economic aspects, patient disability, and work impairment, by discussing the latest population-based studies from the region.

Abstract
Background: Over the past three decades, inflammatory bowel diseases (IBD) have been rapidly increasing in the African, South American, and Asian countries, including Korea. However, in Korea, the public awareness of IBD remains low, and diagnostic delay is not uncommon due to the physicians' lack of clinical experience. It is essential to understand the trends and regional differences in the epidemiology of IBD for proper diagnosis and treatment.Current Concepts: Although lower than those of the West, the prevalence and incidence of IBD in Korea rank among the highest in Asia and are steadily increasing. In the past 10 years, the prevalence of IBD has almost doubled, while its incidence has decreased gradually. As compared to Western IBD patients, Korean patients have higher proportion of proctitis in ulcerative colitis, male predominance, more ileocolonic involvement, and higher incidence of perianal fistula in Crohn disease. There is no single gold standard for the diagnosis of IBD. Thus, diagnosis can be made by clinical evaluation, including a detailed history taking, physical examination, and a combination of endoscopic, radiologic, laboratory, and histologic findings.Discussion and Conclusion: Population-based studies have revealed the current trends and characteristics of the epidemiology of IBD in Korea. Continued education and development of diagnostic tools will help clinicians to diagnose IBD accurately and differentiate it from other diseases such as intestinal tuberculosis.

Abstract
The burden of inflammatory bowel disease (IBD) in Australia is increasing but national data about the current prevalence are limited. We aimed to estimate the prevalence of IBD (including Crohn’s disease, ulcerative colitis and unspecified IBD) as well as Crohn’s disease and ulcerative colitis separately in a general practice population in Australia. We also assessed risk factors associated with Crohn’s disease and ulcerative colitis. We conducted a cross-sectional study using data from MedicineInsight, a national database of general practice electronic health records, from 1 July 2017 to 30 June 2019. The prevalence of IBD was calculated and stratified by sociodemographic characteristics. Logistic regression analysis was conducted to assess risk factors associated with Crohn’s disease and ulcerative colitis. The study comprised 2,428,461 regular patients from 481 practices. The estimated crude prevalence of IBD was 653 per 100,000 patients; Crohn’s disease was 306 per 100,000 and ulcerative colitis was 334 per 100,000. Males were independently associated with a lower risk of Crohn’s disease (OR: 0.86; 95% CI: 0.81, 0.90) but a greater risk of ulcerative colitis (OR: 1.12; 95% CI: 1.06, 1.17) than females. Compared to non-smokers, patients who were current smokers were associated with a greater risk of Crohn’s disease (OR: 1.13; 95% CI: 1.04, 1.23) but a lower risk of ulcerative colitis (OR: 0.52; 95% CI: 0.47, 0.57). Other factors positively associated with both Crohn’s disease and ulcerative colitis were age (≥ 25 years), non-Indigenous status and socioeconomic advantage. Our findings provide a current estimate of the prevalence of IBD, Crohn’s disease and ulcerative colitis in a large national general practice population in Australia and an assessment of the factors associated with Crohn’s disease and ulcerative colitis. These data can assist in estimating the health burden and costs, and planning for health services.

Abstract
OBJECTIVES To determine the age-standardised prevalence of inflammatory bowel disease (IBD) in a metropolitan area of Sydney, with a focus on its prevalence among older people. DESIGN, SETTING Population-based epidemiological study of people with IBD in the City of Canada Bay, a local government area in the inner west of Sydney, during 1 March 2016 - 10 November 2016. PARTICIPANTS Patients diagnosed with confirmed IBD according to the Copenhagen or revised Porto criteria. MAIN OUTCOME MEASURES Crude prevalence of IBD, including Crohn disease and ulcerative colitis; age-standardised prevalence of IBD, based on the World Health Organization standard population; prevalence rates among people aged 65 years or more. RESULTS The median age of 364 people with IBD was 47 years (IQR, 34-62 years); 185 were women (50.8%). The crude IBD prevalence rate was 414 cases (95% CI, 371-456 cases) per 100 000 population; the age-standardised rate was 348 cases (95% CI, 312-385 cases) per 100 000 population. The age-standardised rate for Crohn disease was 166 cases (95% CI, 141-192 cases) per 100 000 population; for ulcerative colitis, 148 cases (95% CI, 124-171 cases) per 100 000 population. The IBD prevalence rate in people aged 65 years or more was 612 cases (95% CI, 564-660 cases) per 100 000, and for those aged 85 years or more, 891 cases (95% CI, 833-949 cases) per 100 000; for people under 65, the rate was 380 cases (95% CI, 342-418 cases) per 100 000. CONCLUSIONS We found that the prevalence of confirmed IBD in a metropolitan sample was highest among older people. Challenges for managing older patients with IBD include higher rates of comorbid conditions, polypharmacy, and cognitive decline, and the immunosuppressive nature of standard therapies for IBD.

Abstract
Inflammatory bowel disease (IBD) is a global disease; its evolution can be stratified into four epidemiological stages: Emergence, Acceleration in Incidence, Compounding Prevalence and Prevalence Equilibrium. In 2020, developing countries are in the Emergence stage, newly industrialized countries are in the Acceleration in Incidence stage, and Western regions are in the Compounding Prevalence stage. Western regions will eventually transition to the Prevalence Equilibrium stage, in which the accelerating prevalence levels off as the IBD population ages and possibly as a result of an unexpected rise in mortality during the COVID-19 pandemic. Mitigating the global burden of IBD will require concerted efforts in disease prevention and health-care delivery innovations that respond to changing demographics of the global IBD population. In this Perspective, we summarize the global epidemiology of IBD and use these data to stratify disease evolution into four epidemiological stages.

Abstract
BACKGROUND AND AIMS Inflammatory bowel disease [IBD] is often one of the most devastating and debilitating chronic gastrointestinal disorders in children and adolescents. The main objectives here were to systematically review the incidence and prevalence of paediatric IBD across all 51 European states. METHODS We undertook a systematic review and meta-analysis based on PubMed, CINAHL, the Cochrane Library, searches of reference lists, grey literature and websites, covering the period from 1970 to 2018. RESULTS Incidence rates for both paediatric Crohn's disease [CD] and ulcerative colitis [UC] were higher in northern Europe than in other European regions. There have been large increases in the incidence of both paediatric CD and UC over the last 50 years, which appear widespread across Europe. The largest increases for CD have been reported from Sweden, Wales, England, the Czech Republic, Denmark and Hungary, and for UC from the Czech Republic, Ireland, Sweden and Hungary. Incidence rates for paediatric CD have increased up to 9 or 10 per 100 000 population in parts of Europe, including Scandinavia, while rates for paediatric UC are often slightly lower than for CD. Prevalence reported for CD ranged from 8.2 per 100 000 to approximately 60 and, for UC, from 8.3 to approximately 30. CONCLUSIONS The incidence of paediatric IBD continues to increase throughout Europe. There is stronger evidence of a north-south than an east-west gradient in incidence across Europe. Further prospective studies are needed, preferably multinational and based on IBD registries, using standardized definitions, methodology and timescales.

Abstract
BACKGROUND Indeterminate colitis [IC] is type of inflammatory bowel disease that exhibits features of both ulcerative colitis [UC] and Crohn's disease [CD]. The present meta-analysis aimed to assess the outcomes of ileal pouch-anal anastomosis [IPAA] in patients with IC in comparison with patients with UC. METHODS A PRISMA-compliant systematic review of the outcome of IPAA in patients with IC was conducted. Electronic databases were searched, and full-text articles were reviewed to extract essential data. Main outcome measures were pouch failure and pouch-related complications. RESULTS A total of 17 studies were included in this meta-analysis. There were 1057 patients with IC and 6511 patients with UC. The weighted mean pouch failure rate in patients with IC was 7.5 (95% confidence interval [CI]: 4.8-10.2) and the weighted mean complication rate was 67 [95% CI: 53.5-80.5]. As compared with patients with UC, patients with IC had significantly higher odds of developing complications after IPAA (odds ratio [OR]: 2.6, p <0.001): pouch fistula [OR:4.98, p <0.001], pelvic sepsis [OR:3.98, p =0.002], pelvic or cuff abscess [OR: 4.5, p <0.001], perineal complications [OR: 5.13, p <0.001], and ultimate diagnosis of CD [OR: 2.57, p <0.001]. Patients with IC and UC had similar odds of pouch failure, pouchitis, anastomotic leak, stricture, and small bowel obstruction. CONCLUSIONS Patients with IC had similar pouch failure rates, yet higher overall complication rates than patients with UC. Complications that tend to be higher after IPAA for patients with IC include pouch fistula, pelvic sepsis, abscess, perineal complications, and ultimate diagnosis of Crohn's disease.

[PMID: 30230160 DOI: 10.1111/imj.14111] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 07/31/2018] [Accepted: 08/29/2018] [Indexed: 01/14/2023]
Abstract
BACKGROUND High inflammatory bowel disease (IBD) rates have been reported in Australasia, but no state-wide studies have yet been performed. AIM This study estimates the 1-year incidence and point prevalence of IBD in the state of Tasmania, Australia. It also reports clinical outcomes after 12 months of diagnosis in an incident cohort. METHODS A prospective, population-based study was performed collecting prevalent and incident state-wide cases from 1 June 2013 to 31 May 2014. Case data were identified from specialist doctors, pathology databases and hospital records. Age-standardised rates (ASR) were calculated based on World Health Organization 2000 standard population characteristics. Incident cases were followed up 12 months after diagnosis. RESULTS There were 1719 prevalent cases: ASR for IBD, Crohn disease (CD), ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU) prevalence rates were 303.9, 165.5, 131.4 and 6.9 per 100 000 respectively. Prevalent CD cases were younger, with greater immunomodulator/biological use and bowel resections. There were 149 incident cases: ASR for IBD, CD, UC and IBDU incidence were 29.5, 15.4, 12.4 and 1.7 per 100 000 respectively. Incident CD cases were more likely than UC or IBDU to require escalation of medical therapy, hospitalisation and bowel resection, especially among those with penetrating or stricturing disease. They had a longer duration of symptoms prior to diagnosis. CONCLUSION IBD prevalence and incidence rates are high in Tasmania, comparable to data from other Australasian studies and those from Northern Europe and America. Poorer 12-month clinical outcomes occurred in complicated CD, with greater use of healthcare resources.

Abstract
BACKGROUND AND AIMS Although the incidence of inflammatory bowel disease [IBD] is increasing in Asia, data on long-term epidemiological trends are limited. We performed a 30-year longitudinal study to investigate temporal trends in the epidemiology of Crohn's disease [CD] and ulcerative colitis [UC] in Seoul, Korea. METHODS This population-based study included 1431 IBD patients [418 CD, 1013 UC] diagnosed between 1986 and 2015 in the Songpa-Kangdong district of Seoul, Korea. Temporal trends in incidence, prevalence, and disease phenotype at diagnosis were analysed. RESULTS The adjusted mean annual incidence rates of CD and UC per 100 000 inhabitants increased from 0.06 (95% confidence interval [CI], 0.05-0.07) and 0.29 [95% CI, 0.27-0.31], respectively, in 1986-1990 to 2.44 [95% CI, 2.38-2.50] and 5.82 [95% CI, 5.73-5.92], respectively, in 2011-2015. Average annual percentage change in IBD incidence was 12.3% in 1986-1995, 12.3% in 1996-2005, and 3.3% in 2006-2015. The male-to-female ratio of the adjusted incidence rate was 3.3:1 for CD and 1.2:1 for UC. Perianal fistula/abscess was present in 43.3% of patients before or at CD diagnosis. At diagnosis, 54.3% of UC patients presented only with proctitis. The adjusted prevalence rate in 2015 was 31.59/100 000 [95% CI, 31.10-32.07] for CD and 76.66/100 000 [95% CI, 75.91-77.42] for UC. CONCLUSIONS The incidence and prevalence of IBD in Korea have continued to increase over the past three decades. Korean patients have distinct demographic and phenotypic characteristics, including a male predominance and high frequency of perianal fistula/abscess in CD and high proportion of proctitis in UC.

Abstract
PURPOSE OF REVIEW Once thought a disease of Western civilizations, the inflammatory bowel diseases (IBD) impose a global burden, now penetrating populations in Asia, Africa, and South America. We summarize similarities and differences in the epidemiology of IBD globally, highlighting gaps in knowledge where future study is needed. RECENT FINDINGS While incidence of IBD is stabilizing (or even decreasing) in many westernized regions, prevalence continues to grow due to a young age of onset and low mortality. In newly westernized regions, IBD is beginning to penetrate populations comparable to the rapid increases seen in North America, Europe, and Oceania in the last century. IBD imposes a significant fiscal and resource burden on healthcare systems. As global prevalence of these diseases continues to increase, we desperately need to anticipate the future burden to proactively prepare our healthcare systems for the challenges of increased patient load and aging populations with comorbid conditions and longer disease course.

Abstract
Background The Global Rating Scale (GRS) is a web-based self-assessment quality improvement tool used to identify gaps in health care, change the focus to patient-centred care and standardize care. There are four levels of achievement ranging from basic-(D) to excellent-(A) service delivery. The goal was to develop a GRS for inflammatory bowel disease (IBD) to improve the quality of care for patients on a system level. Methods The IBD GRS was developed through an iterative process and modeled upon the successful endoscopy GRS programs in the United Kingdom and Canada. Dimensions, items and statements were drafted based on expert opinions, patient-informed quality indicators and best available evidence, then reviewed and modified by a core committee. A working group of IBD and GRS experts voted in-person to establish consensus on the inclusion and quality of statements. Results Two dimensions (Clinical Quality and Quality of Patient Experience), 10 items and 89 statements made up the IBD GRS. There was a 100% response rate for each of the 40 votes for statements in the IBD GRS. All statements within each level received a mean rating score between four (agree) and five (strongly agree). Revisions agreed upon during the voting process were incorporated into the IBD GRS. Group consensus was achieved on the inclusion of statements, and 10 items were selected as standards within the two dimensions. Conclusions We have developed the first IBD GRS with the aim of improving quality of care through ongoing evaluations and improvements by health care teams, focusing on patient-centred care.

Abstract
Aging plays a significant role in the progression of vascular diseases and vascular dysfunction. Activation of the ADP-ribosylation factor 6 and small GTPases by inflammatory signals may cause vascular permeability and endothelial leakage. Pro-inflammatory molecules have a significant effect on smooth muscle cells (SMC). The migration and proliferation of SMC can be promoted by tumor necrosis factor alpha (TNF-α). TNF-α can also increase oxidative stress in SMCs, which has been identified to persuade DNA damage resulting in apoptosis and cellular senescence. Peroxisome proliferator-activated receptor (PPAR) acts as a ligand-dependent transcription factor and a member of the nuclear receptor superfamily. They play key roles in a wide range of biological processes, including cell differentiation and proliferation, bone formation, cell metabolism, tissue remodeling, insulin sensitivity, and eicosanoid signaling. The PPARγ activation regulates inflammatory responses, which can exert protective effects in the vasculature. In addition, loss of function of PPARγ enhances cardiovascular events and atherosclerosis in the vascular endothelium. This appraisal, therefore, discusses the critical linkage of PPARγ in the inflammatory process and highlights a crucial defensive role for endothelial PPARγ in vascular dysfunction and disease, as well as therapy for vascular aging.

Abstract
INTRODUCTION The incidence of inflammatory bowel disease (IBD) in Denmark is among the highest in the world, with Crohn's disease and ulcerative colitis occurring at rates of 9.1 and 18.6 per 100,000 person-years respectively in 2010-2013. Anemia is the most prevalent extraintestinal complication of IBD, most commonly caused by iron deficiency. In treating IBD-associated iron deficiency anemia (IDA), intravenous iron is more effective and better tolerated and shows a faster response than oral iron. The present study evaluated resource use and costs associated with using iron isomaltoside (Monofer; IIM) versus ferric carboxymaltose (Ferinject; FCM) in patients with IDA and IBD in Denmark. METHODS A budget impact model was developed to evaluate the cost of IIM compared with FCM from a Danish healthcare payer perspective. Iron deficits were modeled using dosing tables and a joint distribution of bodyweight [mean 75.4 kg, standard deviation (SD) 17.4 kg] and hemoglobin (mean 10.8 g/dL, SD 1.4 g/dl) based on observational data from patients with IBD. Retreatment frequency was modeled using a pooled retrospective analysis of randomized trial data, and costs were modeled using diagnosis-related groups with an outpatient infusion cost of DKK 2855. RESULTS Using IIM required 1.2 infusions (per treatment) to correct the mean iron deficit compared with 1.6 with FCM. Treating 2.54 patients with IIM would therefore avoid one infusion compared with FCM. Patients using IIM required multiple infusions in 25.0% of cases compared with 64.3% with FCM. Over 5 years, total estimated costs were DKK 21,406 per patient with IIM compared with DKK 28,137 with FCM, corresponding to savings of DKK 6731 with IIM. CONCLUSION Using IIM in place of FCM markedly reduced the number of iron infusions required in patients with IBD and IDA in Denmark. The reduction in infusions was accompanied by reductions in cost compared with FCM. FUNDING Pharmacosmos A/S.

Abstract
AIM To perform a comprehensive review and provide an up-to-date synopsis of the incidence and trends of inflammatory bowel disease (IBD). METHODS We systematically searched the MEDLINE (source PubMed), EMBASE and Cochrane Library databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (period: 1985-2018) to identify studies reporting population-based data on the incidence of pediatric-onset (< 19 years at diagnosis) IBD in full manuscripts. Two authors carried out screening and data extraction. Choropleth interactive maps and temporal trends were used to illustrate the international differences and incidences of and changes in IBD and subtypes. RESULTS In total, one hundred forty studies reporting data from 38 countries were considered in this review. The highest annual pediatric incidences of IBD were 23/100000 person-years in Europe, 15.2/100000 in North America, and 11.4/100000 in Asia/the Middle East and Oceania. The highest annual incidences of Crohn's disease (CD) were 13.9/100000 in North America and 12.3/100000 in Europe. The highest annual incidences of ulcerative colitis (UC) were 15.0/100000 in Europe and 10.6/100000 in North America. The highest annual incidences of IBD-unclassified (IBD-U) were 3.6/100000 in Europe and 2.1/100000 in North America. In the time-trend analyses, 67% of CD, 46% of UC and 11% of IBD-U studies reported an increasing incidence (P < 0.05). The risk of IBD is increasing among first-generation of migrant populations. CONCLUSION Globally, the incidence of IBD varies greatly by geographical areas. The steadily increasing incidence of pediatric IBD over time indicates its emergence as a global disease, suggesting that studies should investigate the environmental risk factors among pediatric cohorts.

Abstract
Background Epidemiologic studies combining exposure and outcome data with the collection of biosamples are needed to study gene-environment interactions that might contribute to the etiology of complex diseases such as pediatric Crohn's disease (CD). Nationwide registries, including those in Denmark and other Scandinavian countries, provide efficient and reliable sources of data for epidemiological studies evaluating the environmental determinants of disease. We performed a pilot study to test the feasibility of collecting salivary DNA to augment registry data in established cases of pediatric CD and randomly selected, population-based controls. Subjects and methods Cases of CD born after 1995 and residing in the central region of Denmark were identified through the Danish National Patient Registry and confirmed by using standard diagnostic criteria. Age- and gender-matched controls were selected at random through the civil registration system. Cases and controls were contacted by mail and telephone and invited to submit a saliva sample. DNA was extracted and genotyped for six CD-associated single-nucleotide polymorphisms (SNPs). Results A total of 53 cases of pediatric CD were invited, and 40 contributed a saliva sample (75% response rate). A total of 126 controls were invited, and 54 contributed a saliva sample (44% response rate). As expected, demographic characteristics did not differ between cases and controls. DNA was successfully isolated from 93 of 94 samples. Genotyping was performed with only 2% undetermined genotypes. For five of six SNPs known to be associated with CD, risk allele frequencies were higher in cases than controls. Conclusion This pilot study strongly supports the feasibility of augmenting traditional epidemiological data from Danish population-based registries with the de novo collection of genetic information from population-based cases and controls. This will facilitate rigorous studies of gene-environment interactions in complex chronic conditions such as CD.

Abstract
BACKGROUND Long-term data on real life use of infliximab (IFX) for inflammatory bowel disease (IBD) are lacking. We studied prescription patterns during the first 16 years following marketing authorization. METHODS In a population-based cohort from the North Denmark Region, all IBD patients exposed to IFX during 1999 to 2014 were identified. RESULTS A total of 623 patients (210 with ulcerative colitis [UC] and 413 with Crohn's disease [CD]) were exposed to IFX. In patients with UC, age at first exposure decreased by 10 months per calendar year (P < 0.05) during the study period. In patients with CD, disease duration at time of first IFX exposure decreased by 7 months per calendar year (P < 0.001). From 2005-2009 to 2010-2014, the proportion of IFX-exposed patients with pancolitis (40% vs 24%, P = 0.04) and the proportion of patients with extensive CD (P = 0.002) decreased. The mean time to discontinuation of IFX remained stable in patients with CD during the study period (2.5-3.0 years) and increased from 0.34 years (2005-2009) to 1.11 years (2010-2015) in patients with UC (P = 0.04). CONCLUSION During the first 16 years postmarketing, age at first exposure to IFX decreased in patients with UC, whereas disease duration at time of first exposure decreased in patients with CD. Also, a significant change toward less extensive disease in both UC and CD patients exposed to IFX was observed. Treatment duration in patients with UC increased during the study period, but did not reach the more constant and longer duration of treatment observed in patients with CD.

Abstract
BACKGROUND Inflammatory bowel disease is a global disease in the 21st century. We aimed to assess the changing incidence and prevalence of inflammatory bowel disease around the world. METHODS We searched MEDLINE and Embase up to and including Dec 31, 2016, to identify observational, population-based studies reporting the incidence or prevalence of Crohn's disease or ulcerative colitis from 1990 or later. A study was regarded as population-based if it involved all residents within a specific area and the patients were representative of that area. To be included in the systematic review, ulcerative colitis and Crohn's disease needed to be reported separately. Studies that did not report original data and studies that reported only the incidence or prevalence of paediatric-onset inflammatory bowel disease (diagnosis at age <16 years) were excluded. We created choropleth maps for the incidence (119 studies) and prevalence (69 studies) of Crohn's disease and ulcerative colitis. We used temporal trend analyses to report changes as an annual percentage change (APC) with 95% CI. FINDINGS We identified 147 studies that were eligible for final inclusion in the systematic review, including 119 studies of incidence and 69 studies of prevalence. The highest reported prevalence values were in Europe (ulcerative colitis 505 per 100 000 in Norway; Crohn's disease 322 per 100 000 in Germany) and North America (ulcerative colitis 286 per 100 000 in the USA; Crohn's disease 319 per 100 000 in Canada). The prevalence of inflammatory bowel disease exceeded 0·3% in North America, Oceania, and many countries in Europe. Overall, 16 (72·7%) of 22 studies on Crohn's disease and 15 (83·3%) of 18 studies on ulcerative colitis reported stable or decreasing incidence of inflammatory bowel disease in North America and Europe. Since 1990, incidence has been rising in newly industrialised countries in Africa, Asia, and South America, including Brazil (APC for Crohn's disease +11·1% [95% CI 4·8-17·8] and APC for ulcerative colitis +14·9% [10·4-19·6]) and Taiwan (APC for Crohn's disease +4·0% [1·0-7·1] and APC for ulcerative colitis +4·8% [1·8-8·0]). INTERPRETATION At the turn of the 21st century, inflammatory bowel disease has become a global disease with accelerating incidence in newly industrialised countries whose societies have become more westernised. Although incidence is stabilising in western countries, burden remains high as prevalence surpasses 0·3%. These data highlight the need for research into prevention of inflammatory bowel disease and innovations in health-care systems to manage this complex and costly disease. FUNDING None.

Abstract
Crohn disease (CD) with complications such as penetrating, stricturing, and perianal disease is called complicated CD. The aim of this study is to test the efficiency with which the CD8CD28/CD8CD28 cell balance can predict a subsequent active stage in patients with newly diagnosed complicated CD.Seventeen patients with complicated CD and 48 CD patients with no complications were enrolled. Blood CD8 T cells were tested from all of the 65 newly diagnosed CD patients upon enrollment. The potential risk factors were compared between the 2 groups. A 30-week follow-up was performed, and the efficiency of the CD8 cell balance at predicting active CD was analyzed using receiver-operating characteristic curves. The cumulative remission lasting rates (CRLRs) were analyzed using the Kaplan-Meier method.Compared with the control CD group, patients with complicated CD were predominantly male and younger in age; they also had lower body mass indices (BMIs), higher Crohn disease activity indices (CDAIs), higher immunosuppressant and steroid prescription rates, and significantly higher surgical rates. The CD8CD28/CD8CD28 balance was associated with BMI, CDAI, steroids, and surgery. The CD8CD28/CD8CD28 ratios were significantly lower at week 0 and on the 6th, 22nd, and 30th week during follow-up with a shorter lasting time of remission for the complicated CD patients. The CD8CD28/CD8CD28 ratio could accurately predict the active stage for the patients with complicated CD, and the highest sensitivity (89.2%) and specificity (85.3%) were found when the ratio was 1.03. Treatment with steroids and surgery, along with a significantly lower CD8CD28/CD8CD28 ratio and lower CRLRs, was closely related to a worse outcome for the patients with complicated CD.Patients requiring steroids and surgery experience more severe disease activity and thus a disequilibrated immunological balance, which could be the main reason for a decreased CD8CD28/CD8CD28 ratio. This ratio can sensitively predict the active stage for patients with complicated CD, and more care should be taken when this ratio is <1.03.

Short-Term Clinical Response to Corticosteroids Can Predict Long-Term Natural History of Ulcerative Colitis: Prospective Study Experience. Dig Dis Sci 2017; 62:1025-1034. [PMID: 28161855 DOI: 10.1007/s10620-017-4450-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2016] [Accepted: 01/10/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND Long-term outcome and natural history of steroid response in adult ulcerative colitis patients based on short-term response is largely unknown. AIM To evaluate whether short-term clinical response at 30 days after steroid initiation for moderate to severe disease can predict long-term outcome. METHODS This prospective observational study recruited 161 patients who received oral/intravenous steroid therapy at our institution from April 2005 to July 2009. Short-term response at 30 days and long-term response at the end of first and third years were measured. Risk factors for long-term outcome at 1 and 3 years were analyzed by multivariate regression model. RESULTS At the end of 30 days, 90 patients (55.9%) had complete response, 47 (29.2%) partial response, and 24 (14.9%) did not respond at all. At the end of first year, 53/90 (60%) complete responders (at 30 days) maintained steroid-free remission when compared to 17/71 (23.9%, p < 0.001) partial/no responders. Similar result was observed at the end of third year (74.7 vs 55.1%, p = 0.017). On multivariable analysis, short-term outcome at 30 days was a predictor of outcome at the end of one year (RR 4.1, 95% CI 2.2-8.5) and 3 years (RR 2.1, 95% CI 1.02-4.5). CONCLUSIONS Short-term response to steroids is a strong predictor of long-term outcome at 1 and 3 years in active ulcerative colitis patients.

Abstract
BACKGROUND Globally, the incidence rates of inflammatory bowel disease (IBD) are increasing; however, data from high-incidence areas are conflicting. Previous studies in Denmark have assessed incidence rates of Crohn's disease (CD) and ulcerative colitis (UC) using short observation periods. AIM To investigate trends in IBD incidence in Denmark over a thirty-year period using nationwide data. METHODS Patients diagnosed with CD or UC in Denmark between 1980 and 2013 were identified in the Danish National Patient Registry (NPR) and included in a nationwide cohort. Incidence rates estimated using different numbers of National Patient Registry records (≥1, 2, 3 or 4) required for case definition were compared. RESULTS From 1980 to 2013 the incidence of CD increased from 5.2 (95% CI: 5.0-5.4) per 100 000 to 9.1 (95% CI: 8.7-9.5) per 100 000 and the incidence of UC increased from 10.7 (95% CI: 10.4-11.0) per 100 000 to 18.6 (95% CI: 18.0-19.2) per 100 000. The increased incidence in CD and UC was independent of gender. The annual increase in incidence rate was greatest in patients aged <15 years for CD and those older than 15 years for UC. For both CD and UC the incidence rates for females were significantly higher than for males. The number of registry records chosen to define IBD cases greatly influenced incidence estimates. CONCLUSIONS The incidence of IBD in Denmark continues to increase and is among the highest in the world. Using at ≥2 records of IBD diagnosis in the Danish National Patient Registry will result in more valid incidence estimates.

Abstract
Essentials Risk of pregnancy-related venous thromboembolism may be increased in inflammatory bowel disease. We performed a study on inflammatory bowel disease and pregnancy-related venous thromboembolism. Inflammatory bowel disease is a risk factor for pregnancy-related venous thromboembolism. Proper disease control before conception is pivotal to avoid venous thromboembolism. SUMMARY Background The incidence of inflammatory bowel disease (IBD) increases, and thus is more common, in pregnant women. IBD is a risk factor for venous thromboembolism (VTE) but it is not clear whether IBD predisposes women to an excess risk of VTE during pregnancy and the postpartum period. Methods This was a nationwide population-based cohort study of all deliveries during 1980-2013 in Denmark, using data from two nationwide health registries: the Danish National Patient Registry and the Medical Birth Registry. We computed incidence rates (IRs) per 1000 person-years, and crude and adjusted relative risks (RRs) with 95% confidence intervals (CIs) for VTE during pregnancy and the first 12 postpartum weeks in women with and without IBD. Results We included 1 046 754 women with 1 978 701 deliveries. We identified 3465 VTE events during pregnancy and 1302 VTE events postpartum. The IR for VTE during pregnancy was 4.20 (95% CI, 2.83-5.58) in IBD patients and 2.41 (95% CI, 2.33-2.50) in women without IBD, corresponding to an RR of 1.72 (95% CI, 1.22-2.43). Adjustment for maternal age and smoking (pregnancies during 1991-2013) yielded an adjusted RR of 1.67 (95% CI, 1.15-2.41). IBD flare was associated with an RR of 2.64 (95% CI, 1.69-4.14) for VTE during pregnancy. The IR for postpartum VTE was 7.03 (95% CI, 3.87-10.20) among IBD patients and 2.88 (95% CI, 2.72-3.04) in women without IBD, corresponding to an adjusted RR of 2.10 (95% CI, 1.33-3.30). Conclusions IBD is a risk factor for VTE during pregnancy and postpartum.

Abstract
The genetics of isolated colonic Crohn's disease place it approximately midway between Crohn's disease with small intestinal involvement and UC, making a case for considering it as a separate condition. We have therefore systematically reviewed its epidemiology, pathophysiology and treatment. Key findings include a higher incidence in females (65%) and older average age at presentation than Crohn's disease at other sites, a mucosa-associated microbiota between that found in ileal Crohn's disease and UC, no response to mesalazine, but possibly better response to antitumour necrosis factor than Crohn's disease at other sites. Diagnostic distinction from UC is often difficult and also needs to exclude other conditions including ischaemic colitis, segmental colitis associated with diverticular disease and tuberculosis. Future studies, particularly clinical trials, but also historical cohorts, should assess isolated colonic Crohn's disease separately.

Abstract
Background Though low compared with those in Western countries, the incidence and prevalence of inflammatory bowel disease (IBD) are rapidly increasing in Asia. If we could understand the differences in IBD epidemiology between Asian and Western countries, we might gain insights into the etiopathogenesis of IBD as well as guidance for personalized therapy. Summary In Asia, unlike in the West, Crohn's disease (CD) predominantly occurs in men and involves a high prevalence of perianal fistulas. Moreover, in Korean CD patients, ileocolonic involvement is predominant, whereas isolated colonic involvement is very uncommon. In both ulcerative colitis (UC) and CD, extraintestinal manifestations, such as primary sclerosing cholangitis, as well as a positive family history of IBD are less frequent in Asian patients. However, as the prevalence of IBD rises in Korea, so does the frequency of a positive family history. While the colectomy rate among Korean UC patients is lower, the intestinal resection rate in CD patients is similar in Korea and in the West. Infectious problems that can adversely influence IBD management are usually more common in Asia. Key Messages IBD in Asians differs from that in Westerners in many aspects, including demographic and clinical characteristics, prognosis, and associated problems.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is often associated with inflammatory bowel disease (IBD; Crohn's disease or ulcerative colitis). However, the prevalence of IBD in HS patients is unknown. OBJECTIVE To determine the prevalence of IBD in HS patients, and determine if patients with HS and IBD have a distinct HS phenotype. METHODS For this multicenter, cross-sectional study, HS patients were asked during their first consultation if they had IBD. The diagnosis of IBD was checked in the medical files, and clinical characteristics were collected. RESULTS IBD had a prevalence of 3.3% (95% CI 2.3-4.4) in 1076 HS patients. The prevalence of Crohn's disease was 2.5% (95% CI 1.6-3.4) and the prevalence of ulcerative colitis was 0.8% (95% CI 0.3-1.4). HS-IBD patients were less frequently obese (13.9% vs 31.2%, P = .04) than HS-only patients, but there were no differences in gender, family history of HS, disease severity, body areas affected by HS, or smoking status. LIMITATIONS The prevalence might be underestimated since HS patients might still develop IBD. CONCLUSION The prevalence of IBD in HS patients (3.3%) is 4-8 times higher than the prevalence in the general northern European population (0.41%-0.74%), however HS-IBD patients do not have a distinct HS phenotype.

Abstract
Aim The aims of The Danish National Registry for Biological Therapy in Inflammatory Bowel Disease are to ensure that biological therapy and the clinical management of patients with inflammatory bowel disease (IBD) receiving biological treatment are in accordance with the national clinical guidelines and, second, the database allows register-based clinical epidemiological research. Study population The study population comprises all Danish patients with IBD (both children and adults) with ulcerative colitis, Crohn’s disease, and IBD unclassified who receive biological therapy. Patients will be enrolled consecutively when biological treatment is initiated. Main variables The variables in the database are: diagnosis, time of diagnosis, disease manifestation, indication for biological therapy, previous biological and nonbiological therapy, date of visit, clinical indices, physician’s global assessment, pregnancy and breastfeeding (women), height (children), weight, dosage (current biological agent), adverse events, surgery, endoscopic procedures, and radiology. Descriptive data Eleven clinical indicators have been selected to monitor the quality of biological treatment. For each indicator, a standard has been defined based on the available evidence. National results will be published in an annual report and local results on a quarterly basis. The indicators will be reported as department-specific proportions with 95% confidence intervals, and the national average will be provided for comparison. An estimated 1,200–1,300 new biological therapies are initiated each year in Danish patients with IBD. Conclusion The database will be available for research during 2016. Data will be made available by The Danish Clinical Registries (www.rkkp.dk).

Abstract
Sex differences have been found in the incidence and progression of inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn's disease. The reported differences in observational studies are controversial, and the effects of sex hormones on the pathogenesis of IBD are not clear. The aim of this study was to analyze sex differences in the progression of experimentally induced colitis. Experimental colitis was induced in adult mice by adding 2% dextran sodium sulfate (DSS) into drinking water. Male and female mice were used as intact, gonadectomized, and supplemented with either estradiol or testosterone. In comparison to males, female mice with induced colitis had significantly longer colon (p < 0.05), lower decrease in body weight (p < 0.001), and lower stool consistency score (p < 0.05). Histopathological analysis showed less inflammatory infiltrates (p < 0.001) and crypt damage (p < 0.001) in female mice. Female mice with colitis had also lower concentration of TNF-α in colon homogenates (p < 0.01). Supplementation with estradiol in ovariectomized mice ameliorated the severity of colitis. Female mice are partially protected against chemically induced colitis. This protection seems to be mediated by estradiol.

Abstract
BACKGROUND The efficacy of infliximab has been demonstrated in patients with both acute severe and moderate-severe ulcerative colitis (UC). However, there is a need for 'real-life data' to ensure that conclusions from trial settings are applicable in usual care. We therefore examined the national experience of anti-tumour necrosis factor-α (TNF-α) therapy in UC. METHODS Case notes review of patients with UC who had received compassionate access (CA) anti-TNF-α therapy from prospectively maintained inflammatory bowel disease databases of six Australian adult teaching hospitals. RESULTS Patients either received drug for acute severe UC (ASUC) failing steroids (n = 29) or for medically refractory UC (MRUC) (n = 35). In ASUC, the treating physicians judged that anti-TNF-α therapy was successful in 20/29 patients (69%); in these cases, anti-TNF-α was able to be discontinued (after 1-3 infusions in 19/20 responders) as clinical remission was achieved. Consistent with this perceived benefit, only 7/29 (24%) subsequently underwent colectomy during a median follow up of 12 months (interquartile range (IQR) 5-16). Eight of the 35 patients with MRUC (23%) required colectomy during a median follow up of 28 months (IQR 11-43). The majority of these patients (20/35 or 57%) had anti-TNF-α therapy for ≥4 months, whereas, 27/29 (93%) of ASUC patients had CA for ≤3 months. CONCLUSIONS These data show an excellent overall benefit for anti-TNF-α therapy in both ASUC and MRUC. In particular, only short-duration anti-TNF-α was required in ASUC. These real-life data thus support the clinical trial data and should lead to broader use of this therapy in UC.

Abstract
BACKGROUND AND AIMS Regional variations in inflammatory bowel disease (IBD) rates have been observed. Limited epidemiological data are available from Australasia. IBD prevalence rates have never been assessed in an Australian population-based setting. In addition, there are few historical IBD incidence data to allow assessment of rate changes. The aims were to calculate Australia's first population-based IBD prevalence rates, to reassess local IBD incidence rates, and to establish a population-based inception cohort. METHODS An observational, prospective population-based epidemiological study was performed to assess IBD prevalence and incidence rates from July 2010 to June 2011 in a geographically defined Australian population (Barwon, Victoria). RESULTS There were 1011 prevalent IBD cases identified, representing a crude point prevalence rate of 344.6 per 100,000 on June 30, 2011. Crohn's disease was the most common prevalent subtype. Seventy-one incident cases of IBD were identified, with a crude incidence rate of 24.2 per 100,000. Crohn's disease was again more common. Local incidence rates have not changed between 2007 and the present study. All incident cases were successfully incorporated into an inception cohort. CONCLUSION The burden of IBD in our local region is high. Demographic similarities allow these results to be applied to the broader Australian community. We propose that the number of existing and new cases each year in Australia has been previously underestimated. These revised figures will be important when planning the provision of health resources for these patients in the future and when assessing need for research funding priorities.

Abstract
Eosinophilic infiltration into oesophageal tissue, typical of eosinophilic oesophagitis (EoE), has been described in several other conditions, including infections, hypersensitivity, and other autoimmune disorders. Since its description, EoE has been associated with an increasing number of diseases also characterized by tissue infiltration, including eosinophilic gastroenteritis and Crohn's disease. While an association between EoE and coeliac disease was previously reported, it is not supported by recent research. In contrast, EoE seems to be common in patients with a history of congenital oesophageal atresia, leading to hypotheses linking both disorders. The prevalence of EoE has also been shown to be eight times higher in patients with connective tissue disorders (CTDs), which has led to the proposal of an EoE-CTD phenotype, although this requires further assessment. This paper reviews the evidence of EoE's associations with several disorders, defining the common bases from an epidemiological, clinical, molecular and genetic perspective whenever possible.

Seasonal variation in onset and relapse of IBD and a model to predict the frequency of onset, relapse, and severity of IBD based on artificial neural network. Int J Colorectal Dis 2015; 30:1267-73.

Abstract
BACKGROUND Previous research has yielded conflicting data as to whether the natural history of inflammatory bowel disease follows a seasonal pattern. The purpose of this study was (1) to determine whether the frequency of onset and relapse of inflammatory bowel disease follows a seasonal pattern and (2) to establish a model to predict the frequency of onset, relapse, and severity of inflammatory bowel disease (IBD) with meteorological data based on artificial neural network (ANN). METHOD Patients with diagnosis of ulcerative colitis (UC) or Crohn's disease (CD) between 2003 and 2011 were investigated according to the occurrence of onset and flares of symptoms. The expected onset or relapse was calculated on a monthly basis over the study period. For artificial neural network (ANN), patients from 2003 to 2010 were assigned as training cohort and patients in 2011 were assigned as validation cohort. Mean square error (MSE) and mean absolute percentage error (MAPE) were used to evaluate the predictive accuracy. RESULTS We found no seasonal pattern of onset (P = 0.248) and relapse (P = 0.394) among UC patients. But, the onset (P = 0.015) and relapse (P = 0.004) of CD were associated with seasonal pattern, with a peak in July and August. ANN had average accuracy to predict the frequency of onset (MSE = 0.076, MAPE = 37.58%) and severity of IBD (MSE = 0.065, MAPE = 42.15%) but high accuracy in predicting the frequency of relapse of IBD (MSE = 0.009, MAPE = 17.1%). CONCLUSION The frequency of onset and relapse in IBD showed seasonality only in CD, with a peak in July and August, but not in UC. ANN may have its value in predicting the frequency of relapse among patients with IBD.

Abstract
BACKGROUND AND AIMS The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), are chronic relapsing disorders of unknown aetiology. The aim of this review is to present the latest epidemiology data on occurrence, disease course, risk for surgery, as well as mortality and cancer risks. MATERIAL AND METHODS Gold standard epidemiology data on the disease course and prognosis of patients with inflammatory bowel disease (IBD) are based on unselected population-based cohort studies. RESULTS The incidence of ulcerative colitis (UC) and Crohn's disease (CD) has increased overall in Europe from 6.0 per 100,000 person-years in UC and 1.0 per 100,000 person-years in CD in 1962 to 9.8 per 100,000 person-years and 6.3 per 100,000 person-years in 2010, respectively. The highest incidence of IBD is found on the Faroe Islands. Overall, surgery rates have been declining over the last decades, partly due to aggressive medical therapy. Among IBD patients, mortality risk is increased by up to 50% in CD when compared to the background population, but this is not the case for UC. In CD, 25 - 50% deaths are disease-specific deaths, e.g. malnutrition, postoperative complications and intestinal cancer. In UC, disease-specific causes of deaths include colorectal cancer (CRC), and surgical and postoperative complications. The risk of CRC and small bowel cancer is increased two- to eightfold among IBD patients. Various subgroups carry increased risk of malignancy, e.g. those with persistent inflammation, long-standing disease, extensive disease, young age at diagnosis, family history of CRC and co-existing primary sclerosing cholangitis. The risk of extra-intestinal cancers, including lymphoproliferative disorders (LD) and intra- and extrahepatic cholangio carcinoma, is significantly higher among IBD patients. CONCLUSION In recent years, self-management and patient empowerment, combined with evolving eHealth solutions, has utilized epidemiological knowledge on disease patterns and has been improving compliance and the timing of adjusting therapies, thus optimizing efficacy by individualizing medication in the community setting.

Abstract
Introduction The present review serves to provide a concise overview of the current knowledge on therapeutic strategies with regard to fibrostenotic lesions in Crohn's disease. Methods A literature search was performed focusing on the last 5 years, and current concepts of pathophysiology, epidemiology, and treatment have been summarized. Results Fibrostenotic lesions in Crohn's disease are currently considered to be a consequence of the chronic inflammatory nature of the disease. Hence, therapeutic strategies are limited to the concept that early treatment of the inflammatory lesions can prevent structural changes, and to various endoscopic and surgical approaches. Direct targeting of the fibrostenotic lesion itself has not been the focus until now. This review will provide an overview of the pathophysiology and epidemiology of fibrostenotic lesions including current therapeutic approaches. Since research with regard to other organ systems and fibrosis is far more advanced, current strategies from available studies in these areas will be discussed. The results and the potential impact for Crohn's disease will be considered. Conclusion The vision of these approaches is to reverse structural changes and restore normal function.

Abstract
INTRODUCTION Incidence of inflammatory bowel disease (IBD) is increasing progressively. Few recent epidemiological prospective studies are available in Spain. The Epicom study, a population-based inception cohort of unselected IBD patients developed within the European Crohn's and Colitis Organization, was started in 2010. Vigo is the only Spanish area participating. OBJECTIVE To describe the incidence of IBD in the Vigo area and the phenotypical characteristics at diagnosis and to compare them with previous data available in Spain. MATERIAL AND METHODS Epidemiological, descriptive, prospective, and population-based study. All incident cases of IBD during 2010 and living in the Vigo area at diagnosis were included. The Copenhagen Diagnostic criteria were used to define cases. Background population at the start of the study was 579,632 inhabitants. Data were prospectively entered in the EpiCom database. RESULTS A total of 106 patients were included (57.5% men, median age 39.5 years). Of them 53 were diagnosed of as Crohn's disease (CD), 47 ulcerative colitis (UC) and six IBD unclassified (IBDU). The incidence rate per 100,000 per year for patients aged 15 years or older was 21.4 (10.8 for CD, 9.4 for UC, 1.2 IBDU). Including pediatric population incidence rates were 18.3 (10.3 CD, 8.7 UC, 1.2 IBDU). Median time since onset of symptoms until diagnosis was 2 months. CONCLUSIONS The incidence rate of IBD in Vigo is the highest compared to former Spanish cohorts, especially in CD patients. Median time since onset of symptoms until diagnosis is relatively short.

Abstract
Background/Aims Despite the rising incidence and prevalence of inflammatory bowel disease (IBD) in Asian populations, data regarding clinical characteristics of patients in Asia based on age at diagnosis are relatively sparse. The aim of this study was to compare clinical characteristics based on the age at diagnosis according to the Montreal Classification in Korean IBD patients. Methods We recruited consecutive patients with IBD at two tertiary hospitals and retrospectively reviewed their medical information. Patients were divided into three groups according to their age at diagnosis: youth (<17 years), young adult (17-40 years), and middle-old (>40 years). The main clinical characteristics for comparison were the achievement of a remission state at the last follow-up visit, cumulative rate of surgery, and cumulative use of immunomodulators and tumor necrosis factor-α (TNFα) blockers during the follow-up period. Results In total, 346 IBD patients were included (Crohn's disease [CD] 146 and ulcerative colitis 200; 36 youth, 202 young adult, and 113 middle-old). The middle-old group with CD was characterized by a predominance of uncomplicated behavior (P=0.013) and a lower frequency of perianal disease (P=0.009). The middle-old group was associated more with a less aggressive disease course than the younger group, as shown by more frequent remission (P=0.004), being less likely to undergo surgery (P<0.001), and lower cumulative use of immunomodulators and TNFα blockers (P<0.001). Conclusions Age at diagnosis according to the Montreal Classification is an important prognostic factor for Korean IBD patients.

Abstract
OBJECTIVE Patients with inflammatory bowel disease (IBD) have an increased risk of extra-intestinal cancer, whereas its impact on cholangiocarcinoma (CC) remains unknown. The aim of this study was to obtain a reliable estimate of the risk of CC in IBD patients through a meta-analysis of clinical observational studies. METHODS Relevant studies were retrieved by searching PUBMED, EMBASE and Web of Science Databases up to Dec 2013. Four population-based case-control and two cohort studies with IBD were identified. Summary relative risk (RR) and its corresponding 95% confidence interval (CI) were calculated using a random-effects model. Potential sources of heterogeneity were detected using subgroup analyses. RESULTS The pooled risk estimate indicated IBD patients were at increased risk of CC (RR = 2.63, 95%CI = 1.47-4.72). Moreover, the increased risk of CC was also associated with Crohn's disease (RR = 2.69, 95%CI = 1.59-4.55) and ulcerative colitis (RR = 3.40, 95%CI = 2.50-4.62). In addition, site-specific analyses revealed that IBD patients had an increased risk of intrahepatic CC (ICC) (RR = 2.61, 95%CI = 1.72-3.95) and extrahepatic CC (ECC) (RR = 1.47, 95%CI = 1.10- 1.97). CONCLUSIONS This study suggests the risk of CC is significantly increased among IBD patients, especially in ICC cases. Further studies are warranted to enable definite conclusions to be drawn.

Abstract
BACKGROUND AND AIM A growing incidence of inflammatory bowel disease (IBD) has been reported recently in southern Europe, with records of pediatric cases confirming these tendencies in Spain. Data on adult populations, however, have not been provided for over 10 years and need to be updated. PATIENTS AND METHODS A multicenter retrospective registry of all adult patients with a diagnosis of IBD, including both Crohn's disease (CD) and ulcerative colitis (UC), attending five public hospitals covering a population of 514 368 inhabitants, was assessed. RESULTS In 2012, the prevalence of CD and UC in adults was 137.17/100 000 inhabitants (95% confidence interval 114-160) and 99.84/100 000 inhabitants (95% confidence interval 79-119), respectively. The mean incidence rate during the period 2000-2012 of CD and UC was 8.9 and 5.6/100 000 inhabitants per year, respectively. Most of our patients (75.55%) had been diagnosed during the last 13 years. CD affected both sexes equally; a trend toward a progressive increase in the age at diagnosis, ileal location, and inflammatory behavior was documented for CD patients. In contrast, UC affected male patients with a higher frequency (57.8%; P=0.015), specifically those older than 40 years of age. Age at UC onset tended to increase progressively from 2000 to 2012 (P<0.001), but the extension on the disease remained unchanged. CONCLUSION IBD is a highly prevalent disorder in our region, reaching the incidence of CD similar to the figures provided for Northern Europe. Changes in IBD localization, behavior, and age at diagnosis were documented during the period 2000-2012.

Abstract
Inflammatory bowel diseases (IBD) are characterised by periods of disease activity and period with disease in remission. In Denmark all patients are seen in hospital settings. The aim of this study was to introduce a nurse-led phone service for stable patients replacing annual visits. The study originated from an outpatient cohort of 1,600 patients with IBD. A research protocol was determined before the intervention was launched, which included surveys among the patients before the intervention, after the intervention, collection of longitudinal data in a three year period, and a clinical audit. Budget impact analysis (BIA) and cost-effectiveness analysis (CEA) were done. Furthermore, the staff evaluated the process. Almost 30% (n = 474) of the total cohort was enrolled in the service. Eighty-seven per cent of the patients welcomed the phone service beforehand. After implementation, 94% of the patients included were pleased with the service. The programme has shortened the waiting time for most other services, but no improvement in the workload was observed. The BIA showed limited savings. The CEA showed an annual saving of 100€ per patient when using the annual phone service over routine visits. In conclusion, changing the method of contact from routine annual visits to annual phone calls from a nurse was feasible and well accepted for stable patients with IBD. The benefits of the service were most marked for the patients.
