Abstract
BACKGROUND Some studies have suggested a reduced life expectancy in patients with Crohn's disease (CD) compared with the general population. The evidence, however, is inconsistent. AIMS Prompted by such studies, we studied survival of CD patients in Örebro county, Sweden. METHODS From the medical records, we identified all patients diagnosed with CD during 1963-2010 with follow-up to the end of 2011. We estimated: overall survival, net and crude probabilities of dying from CD, relative survival ratio (RSR), and excess mortality rate ratios (EMRR) at 10-year follow-up. RESULTS The study included 492 patients (226 males, 266 females). Median age at diagnosis was 32 years (3-87). Net and crude probabilities of dying from CD increased with increasing age and were higher for women. Net survival of patients aged ≥60 at diagnosis was worse for patients diagnosed during 1963-1985 (54%) than for patients diagnosed during 1986-1999 (88%) or 2000-2010 (93%). Overall, CD patients' survival was comparable to that in the general population [RSR = 0.98; 95% CI: (0.95-1.00)]. However, significantly lower than expected survival was suggested for female patients aged ≥60 diagnosed during the 1963-1985 [RSR = 0.47 (0.07-0.95)]. The adjusted model suggested that, compared with diagnostic period 1963-1985, disease-related excess mortality declined during 2000-2010 [EMRR = 0.36 (0.07-1.96)]; and age ≥60 at diagnosis [EMRR = 7.99 (1.64-39.00), reference: age 40-59], female sex [EMRR = 4.16 (0.62-27.85)], colonic localization [EMRR = 4.20 (0.81-21.88), reference: ileal localization], and stricturing/penetrating disease [EMRR = 2.56 (0.52-12.58), reference: inflammatory disease behaviour] were associated with poorer survival. CONCLUSION CD-related excess mortality may vary with diagnostic period, age, sex and disease phenotype.Key summaryThere is inconsistent evidence on life expectancy of patients with Crohn's diseaseCrohn's disease-specific survival improved over time.Earlier diagnosis period, older age at diagnosis, female sex, colonic disease and complicated disease behaviour seems to be associated with excess Crohn's disease-related mortality.

Abstract
BACKGROUND The mortality and risk factors of severe disease and death due to arterial and venous thromboembolism (ATE and VTE, respectively) in patients with inflammatory bowel disease (IBD) remain unclear, especially in Asia. AIMS This study aimed to reveal the mortality and risk factors of TE in IBD patients in Japan. METHODS In the primary surveillance, responses to questionnaires regarding the number of cases of severe TE and TE-associated death in IBD patients in a span of over the past 10 years were obtained from 32 institutions in Japan. In the secondary surveillance, detailed data about IBD patients with TE were collected. The characteristics, laboratory data, therapy status, and situation at the time of TE development were retrospectively collected, and the data were compared between the patients with and without severe TE and TE-associated death. RESULTS The incidence of TE was 1.89% among 31,940 IBD patients. The frequencies of severe TE and TE-associated mortality were 10.7% and 1.0% among the total IBD and TE with IBD patients, respectively. The only risk factor for severe ATE and ATE-associated death was ischemic heart disease. The independent risk factors for severe VTE and VTE-associated death were age (≤ 45 years old), the site of VTE, and disease severity, with anti-TNF therapy as a potential negative risk factor. Patients with severe VTE had a high risk of developing persistent VTE and sequelae. CONCLUSION Unlike ATE, the incidence of VTE was comparable in Asian and Western countries. Therapeutic and prophylactic strategies for managing IBD-associated TE in Asia are urgently needed.

Abstract
BACKGROUND AND AIMS With rising rates of inflammatory bowel diseases [IBD] in older adults, management of comorbidities such as osteoporosis is becoming increasingly important. Hip fracture [HF] is the most serious consequence of low bone mineral quality and is associated with excess risk of mortality. For older IBD patients, there are only limited data available. Therefore, we aimed to assess the association of IBD with HF, and all-cause mortality risk after HF, among IBD patients older than 50 years. METHODS In a national database-registered case-control study, 56 821 HF cases aged ≥50 years, and 113 718 age-, sex- and region-matched non-hip-fracture controls, were analysed between 2012 and 2016. A history of IBD was assessed from data from Austrian social health insurance funds. Logistic regression and Cox proportional multivariate models were used to test the association of IBD with HF and post-hip fracture mortality risk. RESULTS A total of 531 patients were identified with IBD (25.0% men, mean age 81.2 years, standard deviation [SD] 9.7). Analysis, adjusted for anti-osteoporotic treatment, use of glucocorticoids, and selected medications, showed that IBD patients had an increased odds of HF (odds ratio [[OR] 2.22, 95% confidence interval [CI] 1.86-2.64). Patients with Crohn's disease [CD] revealed a higher HF odds in contrast to patients with ulcerative colitis [OR 2.91, 95% CI 2.17-3.89 and OR 1.89, 95% CI 1.52-2.35, respectively]. Overall mortality risk after HF was higher among female CD patients [HR 1.75, 95% CI 1.28-2.41] than in the general population. CONCLUSIONS IBD was strongly associated with HF in older patients. Post-hip fracture mortality risk was elevated particularly in women with CD.

Abstract
BACKGROUND The results from previous studies on association between prostaglandin E receptor 4 (PTGER4) polymorphisms and inflammatory bowel disease (IBD) risk in Caucasian were conflict. The present study aimed to investigate the genetic association by conducting a meta-analysis. METHODS Systematic literature search was conducted through Wiley Online Library, Chinese National Knowledge Infrastructure (CNKI), and PubMed databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to investigate the associations between rs4613763 T/C, 17234657T/G polymorphisms, and IBD risk in Caucasian. RESULTS Twenty case-control studies consisting of 18,495 Crohn disease (CD) patients and 4203 ulcerative colitis (UC) patients, as well as 26,063 controls were included in this meta-analysis. The rs4613763T/C polymorphism had obvious influence on CD, UC risk in Caucasian. However, rs17234657T/G polymorphism had obvious influence on CD but not UC in Caucasian. CONCLUSION This meta-analysis suggested that both the rs4613763 T/C, rs17234657T/G polymorphisms had obvious influence on risk of CD in Caucasian. In addition, rs4613763 T/C, polymorphism had obvious influence on risk of UC in Caucasian.

Abstract
Background Inflammatory bowel disease (IBD) was emerging as a worldwide epidemic disease, and the advanced therapy changed the clinical course and possibly the outcomes. Our previous study reported a higher mortality rate from (IBD) in Taiwan than in Western countries. We proposed to analyze the trend and risk factors of mortality in order to improve the care quality of IBD patients. Methods This retrospective study was conducted to analyze data for January 2001 to December 2015 from a registered database, compiled by the Taiwan’s National Health Insurance. Results Between 2001 and 2015, a total of 3806 IBD patients [Crohn’s disease (CD): 919; ulcerative colitis (UC): 2887] were registered as having catastrophic illness, and 8.2% of these patients died during follow-up. The standardized mortality ratios (SMRs) of CD and UC were 3.72 (95% CI 3.02–4.55) and 1.44 (95% CI 1.26–1.65), respectively, from 2001 to 2015, respectively. A comparison of the periods of 2011–2015 and 2001–2005 revealed a decrease in the mortality rates from both UC and CD. Multivariate Cox proportional hazards analysis identified elderly individuals; sepsis and pneumonia were the risk factors for IBD mortality. The specific risk factors of mortality were liver cancer for UC and surgeries for CD. Conclusion For further decreasing IBD-related mortality in Taiwan, we need to pay special attention toward elderly individuals, infection control, cancer screening and improvement in perioperative care.

Abstract
BACKGROUND Studies examining the mortality risk of inflammatory bowel disease (IBD) have yielded conflicting results, and most do not account for recent advancements made in the treatment of Crohn's disease (CD) and ulcerative colitis (UC). We aim to assess the overall, premature, and cause-specific mortality in IBD patients over a 17-year time period and to evaluate any differences since the introduction of biologic therapy. METHODS A death record case-control study was performed to explore the odds of premature death (before age 65) and all-cause mortality among those with IBD. Cases consisted of IBD patients (1,129 with CD and 841 with UC) who died in New York State (NYS) from 1993 to 2010. Controls (n = 7880) were matched 4:1 on the basis of sex and zip code from those who died in NYS in the same time frame, without an IBD diagnosis. RESULTS Compared with matched controls, those with CD (OR 1.56, CI 95% 1.34-1.82), but not UC (OR 0.72, CI 95% 0.59-0.89), were more likely to die prematurely. Both those with UC and CD were more likely to die from a gastrointestinal cause (CD OR 15.28, 95% CI 12.11-19.27; UC OR 14.02, 95% CI 10.76-18.26). There was no difference in the cause or age of death before and after the introduction of anti-TNF agents in those with IBD. CONCLUSIONS Both CD and UC cases were more likely to die of a gastrointestinal etiology, and CD patients were more likely to die prematurely. There was no significant difference in the premature death, average age of death, and cause of death in this IBD population after the availability of anti-TNF therapy.

Abstract
OBJECTIVE To determine the mortality of Crohn disease (CD) and ulcerative colitis (UC) and temporal trends in mortality. PATIENTS AND METHODS All 895 residents of Olmsted County, Minnesota, first diagnosed as having inflammatory bowel disease (IBD) (411 with CD and 484 with UC) from January 1, 1970, through December 31, 2010, were followed through June 30, 2016. Standardized mortality ratios (SMRs) were computed-expected rates were derived from the US 2010 background population. To determine overall and cause-specific mortality, each patient with IBD was matched with 5 county residents, and Cox regression analysis was used to assess time to death. RESULTS A total of 895 patients with IBD and 4475 patients without IBD were included. Seventy-four patients with CD died compared with 59.2 expected (SMR, 1.25; 95% CI, 0.98-1.57), and 77 patients with UC died compared with 108.1 expected (SMR, 0.71; 95% CI, 0.56-0.89). In CD, the risk of dying was significantly associated with diagnosis from 1970 through 1979 (SMR, 1.90; 95% CI, 1.24-2.78). Of those diagnosed after 1980, the risk of dying in patients with CD was similar to the US background population. In UC, the risk of dying was less than expected in all periods of diagnosis. In the Cox regression analysis, overall mortality was not significantly higher in CD (hazard ratio [HR], 1.26; 95% CI, 0.97-1.63) or UC (HR, 0.89; 95% CI, 0.70-1.14) compared with the comparison cohort. The risk of dying of digestive diseases (HR, 3.70; 95% CI, 1.24-11.0) and respiratory diseases (HR, 2.72; 95% CI, 1.36-5.44) was increased in CD but not UC. CONCLUSION In this cohort, overall mortality in patients with CD diagnosed after 1980 did not differ from that in the US background population. Overall mortality in patients with UC diagnosed from 1970 through 2010 was lower than the expected mortality.

Abstract
AIMS Budesonide with multi-matrix technology (MMX) is an oral corticosteroid, shown to have high topical activity against ulcerative colitis (UC) while maintaining low systemic bioavailability with few adverse events. The aim of this study was to evaluate the cost-effectiveness of budesonide MMX versus commonly used corticosteroids, in the second-line treatment of active mild-to-moderate UC in the Netherlands. MATERIALS AND METHODS An eight-state Markov model with an 8 week cycle length captured remission, four distinct therapy stages, hospitalization, possible colectomy and mortality. Remission probability for budesonide MMX was based on the CORE-II study. Population characteristics were derived from the Dutch Inflammatory Bowel Disease South Limburg cohort (n = 598) and included patients with proctitis (39%), left-sided (42%) and extensive disease (19%). Comparators (topical budesonide foam and enema, oral budesonide and prednisolone) were selected based on current Dutch clinical practice. Treatment effects were evaluated by network meta-analysis using a Bayesian framework. Cost-effectiveness analysis was performed over a 5 year time horizon from a societal perspective, with costs, health-state and adverse event utilities derived from published sources. Outcomes were weighted by disease extent distribution and corresponding comparators. RESULTS Budesonide MMX was associated with comparable quality-adjusted life year (QALY) gain versus foam and oral formulations (+0.01 QALYs) in the total UC population, whilst being cost-saving (EUR 366 per patient). Probabilistic sensitivity analysis evaluated an 86.6% probability of budesonide MMX being dominant (cost-saving with QALY gain) versus these comparators. Exploratory analysis showed similar findings versus prednisolone. LIMITATIONS Differing definitions of trial end-points and remission across trials meant indirect comparison was not ideal. However, in the absence of head-to-head clinical data, these comparisons are reasonable alternatives and currently offer the only comparison of second-line UC treatments. CONCLUSIONS In the present analysis, budesonide MMX was shown to be cost-effective versus comparators in the total UC population, for the second-line treatment of active mild-to-moderate UC in the Netherlands.

Abstract
Background The risk of cardiovascular disease occurrence and death in inflammatory bowel disease patients is still unclear. Design Meta-analysis. Methods Pertinent studies were identified by searching articles in PubMed and Web of Knowledge to December 2017 and reviewing the reference lists of the retrieved articles. We used the fixed-effect model to pool the study-specific estimates when there was no indication of heterogeneity; otherwise, the random-effect model was used. Results A total of 27 articles was included, of which 11 studies reported the risk of cardiovascular disease incidence and 16 studies reported the risk of cardiovascular disease death. The pooled relative risks were 1.25 (95% confidence interval (CI): 1.08, 1.44), 1.17 (95% CI: 1.07, 1.27) and 1.12 (95% CI: 1.05, 1.21) for cerebrovascular disease, coronary heart disease and myocardial infarction, respectively. In particular, the pooled relative risk was much higher in females. The pooled standardized mortality ratios were 1.01 (95% CI: 0.90, 1.14) for Crohn's disease patients and 0.93 (95% CI: 0.86, 1.01) for ulcerative colitis patients with low heterogeneity across studies. No publication bias was detected. Conclusions There was a positive association between inflammatory bowel disease and higher risk of cardiovascular disease incidence, particularly in females. Such an association was not observed for cardiovascular disease mortality.

Abstract
BACKGROUND & AIMS A comprehensive knowledge of the natural history of ulcerative colitis (UC) helps understand disease evolution, identify poor prognostic markers and impact of treatment strategies, and facilitates shared decision-making. We systematically reviewed the natural history of UC in adult population-based cohort studies with long-term follow-up. METHODS Through a systematic literature review of MEDLINE through March 31, 2016, we identified 60 studies performed in 17 population-based inception cohorts reporting the long-term course and outcomes of adult-onset UC (n = 15,316 UC patients). RESULTS Left-sided colitis is the most frequent location, and disease extension is observed in 10%-30% of patients. Majority of patients have a mild-moderate course, which is most active at diagnosis and then in varying periods of remission or mild activity; about 10%-15% of patients experience an aggressive course, and the cumulative risk of relapse is 70%-80% at 10 years. Almost 50% of patients require UC-related hospitalization, and 5-year risk of re-hospitalization is ∼50%. The 5-year and 10-year cumulative risk of colectomy is 10%-15%; achieving mucosal healing is associated with lower risk of colectomy. About 50% of patients receive corticosteroids, although this proportion has decreased over time, with a corresponding increase in the use of immunomodulators (20%) and anti-tumor necrosis factor (5%-10%). Although UC is not associated with an increased risk of mortality, it is associated with high morbidity and work disability, comparable to Crohn's disease. CONCLUSIONS UC is a disabling condition over time. Prospective cohorts are needed to evaluate the impact of recent strategies of early use of disease-modifying therapies and treat-to-target approach with immunomodulators and biologics. Long-term studies from low-incidence areas are also needed.

Abstract
PURPOSE OF REVIEW Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are chronic, relapsing diseases with unknown etiologies. The purpose of this review is to present the natural disease course evidenced in the latest epidemiology data. RECENT FINDINGS The prevalence of IBD is rapidly increasing, affecting five million patients worldwide with the highest incidence observed in Northern Europe and Northern America. It has been shown that both CD and UC patients are at an increased risk for developing cancer of the gastrointestinal tract compared to the general population. Though the disease course of IBD is unpredictable, the rate of surgical treatment has declined potentially as a consequence of the introduction of immunomodulators and new biologic treatment options. Treatments with biological agents and/or immunosuppressive drugs as well as disease monitoring with eHealth devices seem to have a positive impact on the disease course. However, long-term follow-up studies are still lacking and therefore no reliable conclusions can be drawn as of yet. Medical compliance is paramount in the treatment of IBD, and continuous research focusing on approaches that increase compliance is also necessary.

Abstract
The incidence and prevalence of childhood-onset inflammatory bowel diseases (IBD), including subtypes Crohn's disease and ulcerative colitis, have risen dramatically in recent years, and have emerged globally as important pediatric chronic diseases. Therefore, health care providers are more frequently encountering very young children with IBD, a chronic and incurable condition requiring life-long therapy. These children are living long lives with IBD and therefore knowledge of long-term outcomes is increasingly important to better counsel families and determine the best course of treatment. This review summarizes the current knowledge and literature surrounding long-term outcomes of pediatric IBD, with emphasis on the following areas: need for surgery due to complicated disease behavior, risk of disease remission and recurrence, mental health and psychosocial well-being, educational outcomes, linear growth impairment, cancer risk, and mortality. In addition, we review recent research about predicting negative long-term outcomes in children with IBD.

Abstract
BACKGROUND AND AIM Limited data are available regarding mortality from inflammatory bowel disease in non-Caucasian populations. Herein, we evaluated overall and cause-specific mortality in a hospital-based cohort of Korean inflammatory bowel disease patients. METHODS We determined mortality in 2414 Crohn's disease patients and 2798 ulcerative colitis patients diagnosed between 1977 and 2013. Standardized mortality ratios were calculated in several demographic and phenotypic subgroups. RESULTS During the mean 9-year follow up, 114 patients died: 35 with Crohn's disease and 79 with ulcerative colitis. The overall standardized mortality ratios were 1.40 (95% confidence interval: 0.97-1.94) in Crohn's disease and 0.73 (0.58-0.91) in ulcerative colitis. In Crohn's disease, female sex, age < 30 years at diagnosis, disease duration > 10 years, ileocolonic disease at diagnosis, perianal fistula, intestinal resection, and ever-use of corticosteroids were associated with higher mortality. In ulcerative colitis, male sex, age ≥ 30 years at diagnosis, disease duration ≤ 5 years, proctitis at diagnosis, and no history of colectomy were associated with lower mortality, while primary sclerosing cholangitis was associated with higher mortality. In both Crohn's disease and ulcerative colitis, high mortality rates due to nonmalignant gastrointestinal causes (standardized mortality ratios: 4.59 and 2.32, respectively) and gastrointestinal malignancies (standardized mortality ratios: 16.59 and 3.45, respectively) were observed. Cardiovascular mortality was lower in ulcerative colitis (standardized mortality ratio: 0.47). CONCLUSIONS The overall mortality tended to be higher in Crohn's disease patients than in the general population; it was slightly lower in ulcerative colitis patients than in the general population.

Abstract
BACKGROUND Inflammatory bowel diseases are common in Europe, with prevalences as high as 1 in 198 persons (ulcerative colitis) and 1 in 310 persons (Crohn's disease). METHODS This review is based on pertinent articles retrieved by a search in PubMed and in German and European guidelines and Cochrane reviews of controlled trials. RESULTS Typically, the main clinical features of inflammatory bowel diseases are diarrhea, abdominal pain, and, in the case of ulcerative colitis, peranal bleeding. These diseases are due to a complex immunological disturbance with both genetic and environmental causes. A defective mucosal barrier against commensal bowel flora plays a major role in their pathogenesis. The diagnosis is based on laboratory testing, ultrasonography, imaging studies, and, above all, gastrointestinal endoscopy. Most patients with Crohn's disease respond to budesonide or systemic steroids; aminosalicylates are less effective. Refractory exacerbations may be treated with antibodies against tumor necrosis factor (TNF) or, more recently, antibodies against integrin, a protein of the cell membrane. In ulcerative colitis, aminosalicylates are given first; if necessary, steroids or antibodies against TNF-α or integrin are added. Maintenance therapy to prevent further relapses often involves immunosuppression with thiopurines and/or antibodies. Once all conservative treatment options have been exhausted, surgery may be necessary. CONCLUSION The treatment of chronic inflammatory bowel diseases requires individually designed therapeutic strategies and the close interdisciplinary collaboration of internists and surgeons.

Abstract
BACKGROUND There is no consensus on the leading causes of death among inflammatory bowel diseases (IBD) patients. AIM We present the results of an extended follow-up of the population-based Florence IBD cohort, including 689 ulcerative colitis and 231 Crohn's disease patients. METHODS The causes of death of cohort members were determined through linkage with the local mortality registry. We calculated standardized mortality ratios (SMR) and 95% confidence intervals (95%CI) by applying gender-, age- and calendar time-death rates to person-years at risk. RESULTS Ulcerative colitis patients had overall mortality comparable to the general population (SMR 0.99, 95%CI 0.85-1.14), though being at increased risk of dying from Hodgkin's disease (SMR 11.74, 95%CI 2.94-46.94), rectal cancer (SMR 3.69, 95%CI 1.66-8.22) and Alzheimer's disease (2.40, 95%CI 1.00-5.76). Crohn's disease patients had an increased overall mortality (SMR 1.79, 95%CI 1.39-2.27) and were at higher risk of dying from cancer (SMR 2.57, 95%CI 1.28-5.13) and non-cancer diseases of the respiratory system (SMR 2.51, 95%CI 1.05-6.04), brain cancer (SMR 6.26, 95%CI 1.57-25.02) and non-cancer diseases of the genitourinary system (SMR 4.38, 95%CI 1.10-17.52). CONCLUSIONS IBD patients should be offered counselling on risk reduction strategies, as much of their mortality excess is potentially avoidable.

Abstract
BACKGROUND Mortality rates greater than in the general population have been reported in the population with Crohn's disease (CD), but reports for ulcerative colitis (UC) are conflicting. Trends with time were rarely described. We aimed to assess whether CD and UC mortality in Québec differs from that in the general population and to describe the trends over a 10-year observation period. METHODS This is a population-based cohort study using the Québec administrative health databases and death certificates registry. All-cause and cause-specific standardized mortality ratios (SMRs) were computed for 1999 to 2008. A time trend analysis was used to assess changes in the SMR with the calendar year. RESULTS All-cause mortality was significantly increased in CD and UC compared to the general population: SMR: CD 1.45 (95% confidence interval: 1.34-1.58), UC 1.21 (95% confidence interval: 1.12-1.32). In CD, mortality from digestive conditions, all neoplasms, digestive neoplasms, and colorectal, lymphatic, and lung cancer was significantly higher than in the general population. In UC, mortality from digestive, respiratory, and infectious conditions was also significantly increased. In both CD and UC, there was a decrease with time in all-cause SMRs and in digestive conditions, digestive neoplasms, colorectal cancer, and infectious diseases. SMRs for lung cancer and respiratory conditions increased over time in CD. CONCLUSIONS All-cause mortality was significantly higher in CD and UC populations than in the general population. However, a decreasing trend with time was observed in all-cause and some cause-specific SMRs. In CD, SMRs for lung cancer and respiratory conditions increased during the observation period.

Abstract
Inflammatory bowel disease (IBD) describes a group of closely related yet heterogeneous predominantly intestinal disease processes that are a result of an uncontrolled immune mediated inflammatory response. It is estimated that approximately one and a half million persons in North America have IBD. Pathogenesis of IBD involves an uncontrolled immune mediated inflammatory response in genetically predisposed individuals to a still unknown environmental trigger that interacts with the intestinal flora. There continues to be an enormous amount of information emanating from epidemiological studies providing expanded insight into the occurrence, distribution, determinants, and mechanisms of inflammatory bowel disease.

Abstract
OBJECTIVE Published studies on the association between NCF4 rs4821544T/C polymorphism and inflammatory bowel disease (IBD) risk in Caucasian have yielded conflicting results. The present study aimed to provide more reliable conclusions by conducting a meta-analysis. METHODS All eligible studies were extracted from Wiley Online Library, Chinese National Knowledge Infrastructure and PubMed databases. Odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the associations between rs4821544T/C polymorphism and IBD risk in Caucasian. RESULTS A total of 13 case-control studies comprising 7441 Crohn's disease (CD) patients, 2565 ulcerative colitis (UC) patients and 8315 controls were included in this meta-analysis. Significant associations were found between CD and the rs4821544T/C polymorphism in three genetic models (C vs T: OR = 1.11, 95 % CI: 1.06, 1.16, P = 0.000; CC vs TT: OR = 1.31, 95 % CI: 1.18, 1.45, P = 0.000; CC/TC vs TT: OR = 1.07, 95 % CI: 1.01, 1.13, P = 0.014; CC vs TC/TT OR = 1.28, 95 % CI: 1.16, 1.42, P = 0.000). However, significant associations were not found in UC under any genetic models (C vs T: OR = 1.04, 95 % CI: 0.97, 1.11, P = 0.264; CC vs TT: OR = 1.10, 95 % CI: 0.93, 1.30, P = 0.284; TC vs TT: OR = 1.04, 95 % CI: 0.95, 1.13, P = 0.429; CC/TC vs TT: OR = 1.04, 95 % CI: 0.95, 1.13, P = 0.390; CC vs TC/TT OR = 1.07, 95 % CI: 0.91, 1.26, P = 0.409). CONCLUSION This meta-analysis suggested that the rs4821544T/C polymorphism was associated with CD, but not UC in Caucasian.

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
Patients with inflammatory bowel diseases (IBDs) are at increased risk of colorectal cancer (CRC), but the risk varies between different studies and seems to be decreasing. The cumulative risk of CRC has been reported to be 1%, 2%, and 5% after 10, 20, and over 20 years of disease duration, respectively, in recent meta-analysis. Disease duration and grade of inflammation are the main driving forces of dysplasia and CRC development. Also, the risk of extraintestinal cancers is increased in IBD, where the degree of immunosuppression and its duration are the most important risk factors. Most important extraintestinal malignancies are lymphomas and non-melanoma skin cancers, both of which are increased in patients receiving thiopurines. Also, extraintestinal manifestations or concomitant diseases such as primary sclerosing cholangitis predispose IBD patients to malignancies such as cholangiocarcinoma. History of previous cancer increases the risk of developing either new or recurrent cancers and should be taken into account when choosing therapy and planning surveillance. Dysplasia and cancer screening and surveillance must be individualized according to patients' risk factors. Malignancies are the second most common cause of death after cardiovascular diseases in both genders in patients with IBD.

Abstract
BACKGROUND Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC) is perceived to harbor significant morbidity but limited excess mortality, thought to be driven by colon cancer, compared with the general population. Recent studies suggest mortality rates seem higher than previously understood, and there are emerging threats to mortality. Clinicians must be up to date and able to clearly convey the causes of mortality to arm individual patients with information to meaningfully participate in decisions regarding IBD treatment and maintenance of health. METHODS A MEDLINE search was conducted to capture all relevant articles. Keyword search included: "inflammatory bowel disease," "Crohn's disease," "ulcerative colitis," and "mortality." RESULTS CD and UC have slightly different causes of mortality; however, malignancy and colorectal cancer-associated mortality remains controversial in IBD. CD mortality seems to be driven by gastrointestinal disease, infection, and respiratory diseases. UC mortality was primarily attributable to gastrointestinal disease and infection. Clostridium difficile infection is an emerging cause of mortality in IBD. UC and CD patients have a marked increase in risk of thromboembolic disease. With advances in medical and surgical interventions, the exploration of treatment-associated mortality must continue to be evaluated. CONCLUSIONS Clinicians should be aware that conventional causes of death such as malignancy do not seem to be as significant a burden as originally perceived. However, emerging threats such as infection including C. difficile are noteworthy. Although CD and UC share similar causes of death, there seems to be some differences in cause-specific mortality.

Mortality and extraintestinal cancers in patients with primary sclerosing cholangitis and inflammatory bowel disease. J Crohns Colitis 2014; 8:956-63. [PMID: 24559536 PMCID: PMC4136996 DOI: 10.1016/j.crohns.2014.01.019] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2013] [Revised: 01/20/2014] [Accepted: 01/24/2014] [Indexed: 12/17/2022]
Abstract
INTRODUCTION Primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) frequently co-occur. PSC is associated with increased risk for colorectal cancer (CRC). However, whether PSC is associated with increased risk of extraintestinal cancers or affects mortality in an IBD cohort has not been examined previously. METHODS In a multi-institutional IBD cohort of IBD, we established a diagnosis of PSC using a novel algorithm incorporating narrative and codified data with high positive and negative predictive value. Our primary outcome was occurrence of extraintestinal and digestive tract cancers. Mortality was determined through monthly linkage to the social security master death index. RESULTS In our cohort of 5506 patients with CD and 5522 patients with UC, a diagnosis of PSC was established in 224 patients (2%). Patients with IBD-PSC were younger and more likely to be male compared to IBD patients without PSC; three-quarters had UC. IBD-PSC patients had significantly increased overall risk of cancers compared to patients without PSC (OR 4.36, 95% CI 2.99-6.37). Analysis of specific cancer types revealed that a statistically significant excess risk for digestive tract cancer (OR 10.40, 95% CI 6.86-15.76), pancreatic cancer (OR 11.22, 95% CI 4.11-30.62), colorectal cancer (OR 5.00, 95% CI 2.80-8.95), and cholangiocarcinoma (OR 55.31, 95% CI 22.20-137.80) but not for other solid organ or hematologic malignancies. CONCLUSIONS PSC is associated with increased risk of colorectal and pancreatobiliary cancer but not with excess risk of other solid organ cancers.

Mortality and causes of death in patients with inflammatory bowel disease: a nationwide register study in Finland. J Crohns Colitis 2014; 8:1088-96. [PMID: 24630486 DOI: 10.1016/j.crohns.2014.02.015] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2013] [Revised: 01/29/2014] [Accepted: 02/13/2014] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIM Increased mortality has been reported in Crohn's disease (CD) but mostly not in ulcerative colitis (UC). We evaluated the overall and cause-specific mortality in a nationwide cohort of patients with inflammatory bowel disease (IBD) in Finland. METHODS A total of 21,964 patients with IBD (16,649 with UC and 5315 with CD) from the Special Reimbursement register were diagnosed 1987-1993 and 2000-2007 and followed up to the end of 2010 by collating these figures with the national computerized Cause-of-Death Register of Statistics Finland. In each cause-of-death category, the number of deaths reported was compared to that expected in general population, and expressed as a standardized mortality ratio (SMR). RESULTS Overall mortality was increased among patients with CD (SMR 1.33, 95% confidence interval 1.21-1.46) and UC (1.10, 1.05-1.15). SMR was significantly increased for gastrointestinal causes in CD (6.53, 4.91-8.52) and UC (2.81, 2.32-3.34). Patients with UC were found also to have increased SMR from pulmonary (1.24, 1.02-1.46) and cardiovascular disease (1.14, 1.06-1.22) and cancers of the colon (1.90, 1.38-2.55), rectum (1.79, 1.14-2.69) and biliary tract (5.65, 3.54-8.54), whereas SMR from alcohol-related deaths was decreased (0.54, 0.39-0.71). Patients with CD had a significantly increased SMR for pulmonary diseases (2.01, 1.39-2.80), infections (4.27, 2.13-7.63) and cancers of the biliary tract (4.51, 1.23-11.5) and lymphoid and hematopoietic tissue (2.95, 1.85-4.45). CONCLUSIONS In this Finnish nationwide study increased overall mortality in both CD and UC was observed. The excess mortality of 14% in IBD is mainly due to deaths related to inflammation in the gut.

Abstract
OBJECTIVE Patients with inflammatory bowel disease (IBD) are at increased risk of having venous thromboembolism. The magnitude of this risk has yet to be determined. The question of whether IBD patients have an increased risk of arterial thromboembolism and cardiovascular (CV) mortality remains controversial. DESIGN We searched MEDLINE, Cochrane Library, EMBASE and international conference abstracts and included all controlled observational studies that evaluated the incidence of venous and/or arterial thromboembolic events (TE) and CV mortality in adult IBD. RESULTS 33 studies enrolling 207,814 IBD patients and 5,774,898 controls and capturing 3,253,639 hospitalizations of IBD patients and 936,411,223 hospitalizations of controls reported a risk of arterial and/or venous TE or CV mortality were included. The risk of venous TE was increased in IBD patients compared to the general population (RR, 1.96; 95% CI, 1.67-2.30) contrary to the risk of arterial TE (RR, 1.15; 95% CI, 0.91-1.45). There was an increased risk of deep venous thrombosis (RR, 2.42; 95% CI, 1.78-3.30), pulmonary embolism (RR, 2.53; 95% CI, 1.95-3.28), ischemic heart disease (RR, 1.35; 95% CI, 1.19-1.52) and mesenteric ischemia (RR, 3.46; 95% CI, 1.78-6.71). Differences in methodology were great between studies resulting in a significant heterogeneity in all previous analysis. CV mortality in IBD patients was not increased compared to the general population (SMR, 1.03; 95% CI, 0.93-1.14). CONCLUSION The risk of TE is increased in patients with IBD. This difference is mainly due to an increased risk of venous TE. There is no increased risk of arterial TE or CV mortality in IBD patients, but an increased risk of both ischemic heart disease and mesenteric ischemia.

Abstract
OBJECTIVE Population-based studies have shown a slightly decreased life expectancy in patients with Crohn's disease (CD). The primary aim of the present study was to evaluate mortality and causes of death 20 years after the diagnosis in a well defined population-based cohort of CD patients in Norway. DESIGN The Inflammatory Bowel South-Eastern Norway study has prospectively followed all patients diagnosed with CD in the period between 1 January 1990 and 31 December 1993 in four geographically well-defined areas. All patients (n=237) were age and sex matched with 25 persons from the same county selected at random from the general population. Data on death and causes of deaths were collected from the Norwegian Causes of Death Register. All causes and cause-specific mortality (gastrointestinal cancer, cancer and heart disease) were modelled with Cox regression model stratified by matched sets. Results are expressed as HRs with 95% CIs. RESULTS There was no significant difference between CD patients and controls in overall mortality (HR=1.35, 95% CI 0.94 to 1.94, p=0.10). Furthermore, there were no marked differences in deaths from gastrointestinal cancer, other cancers or cardiovascular diseases in the CD group compared with the controls. In the CD group, 13.9% had died compared with 12.7% in the control group (p=0.578). CONCLUSIONS In our population-based inception cohort followed for 20 years, there was no increased mortality or more deaths from cancer compared with the general population.

Abstract
Crohn’s disease (CD) is a multifactorial potentially debilitating disease. It has a variable disease course, but the majority of patients eventually develop penetrating or stricturing complications leading to repeated surgeries and disability. Studies on the natural history of CD provide invaluable data on its course and clinical predictors, and may help to identify patient subsets based on clinical phenotype. Most data are available from referral centers, however these outcomes may be different from those in population-based cohorts. New data suggest the possibility of a change in the natural history in Crohn’s disease, with an increasing percentage of patients diagnosed with inflammatory disease behavior. Hospitalization rates remain high, while surgery rates seem to have decreased in the last decade. In addition, mortality rates still exceed that of the general population. The impact of changes in treatment strategy, including increased, earlier use of immunosuppressives, biological therapy, and patient monitoring on the natural history of the disease are still conflictive. In this review article, the authors summarize the available evidence on the natural history, current trends, and predictive factors for evaluating the disease course of CD.

Abstract
Background The incidence of the inflammatory bowel diseases (IBD), ulcerative colitis (UC) and Crohn’s disease (CD), has been increasing in Asia. We probed the nationwide registered database to assess the incidence, prevalence, gender distribution, age of diagnosis and the survival status of IBD patients in Taiwan. Methods A retrospective study was conducted to analyze the registered database compiled by the National Health Insurance provided by the Department of Health, Taiwan, from January 1998 through December 2008. Results A total of 1591 IBD patients were registered from 1998 to 2008 in Taiwan (CD: 385; UC: 1206). The incidence of CD increased from 0.19/100,000 in 1998 to 0.24/100,000 in 2008. The incidence of UC increased from 0.61/100,000 in 1998 to 0.94/100,000 in 2008. The prevalence of CD increased from 0.19/100,000 in 1998 to 1.78/100,000 in 2008. The prevalence of UC increased from 0.61/100,000 in 1998 to 7.62/100,000 in 2008. Male to female ratio for CD was 2.22 and 1.64 for UC. Age of registered for CD was predominantly between 20 to 39, and for UC between 30 to 49 years of age. The standardized mortality ratio (95% CI) was 4.97 (3.72–6.63) for CD and 1.78 (1.46–2.17) for UC, from 1998 to 2008 in Taiwan. Conclusions Using the Taiwan nationwide database for IBD, the incidence and prevalence of IBD in Taiwan significantly increased from 1998 to 2008. The mortality rate was higher for CD patients than UC patients, and both were higher than the general population.

Abstract
OBJECTIVES Although the incidence of pediatric inflammatory bowel disease (IBD) continues to rise in Northern France, the risks of death and cancer in this population have not been characterized. METHODS All patients <17 years, recorded in EPIMAD registry, and diagnosed between 1988 and 2004 with Crohn's disease (CD) or ulcerative colitis (UC) were included. The observed incidences of death and cancer were compared with those expected in the regional general population obtained by French Statistical Institute (INSEE) and the cancer Registry from Lille. Comparisons were performed using Fisher's exact test and were expressed using the standardized mortality ratios (SMRs) and standardized incidence ratios. RESULTS A total of 698 patients (538 with CD and 160 with UC) were identified; 360 (52%) were men, the median age at IBD diagnosis was 14 years (12-16) and the median follow-up time was 11.5 years (7-15). During follow-up, the mortality rate was 0.84% (6/698) and did not differ from that in the reference population (SMR=1.4 (0.5-3.0); P=0.27). After a median follow-up of 15 years (10-17), 1.3% of patients (9/698) had a cancer: colon (n=2), biliary tract (cholangiocarcinoma; n=1), uterine cervix (n=1), prepuce (n=1), skin (basal cell carcinoma (n=2), hematological (acute leukemia; n=1), and small bowel carcinoid (n=1). There was a significantly increased risk of cancer regardless of gender and age (standardized incidence ratio=3.0 (1.3-5.9); P<0.02). Four out of nine patients who developed a cancer had received immunosuppressants or anti-tumor necrosis factor-α therapy (including combination therapy in three patients). CONCLUSIONS In this large pediatric population-based IBD cohort, mortality did not differ from that of the general population but there was a significant threefold increased risk of neoplasia.

Abstract
BACKGROUND To describe the clinical characteristics of inflammatory bowel disease (IBD) at diagnosis in The Netherlands at the population level in the era of biologics. METHODS All patients with newly diagnosed IBD (diagnosis made between January 1, 2006 and January 1, 2007) followed in 9 general hospitals in the southwest of the Netherlands were included in this population-based inception cohort study. RESULTS A total of 413 patients were enrolled, of which 201 Crohn's disease (CD) (48.7%), 188 ulcerative colitis (UC) (45.5%), and 24 IBD unclassified (5.8%), with a median age of 38 years (range, 14-95). Seventy-eight patients with CD (38.8%) had ileocolonic disease and 73 patients (36.3%) had pure colonic disease. In 8 patients (4.0%), the upper gastrointestinal tract was involved. Nineteen patients with CD (9.5%) had perianal disease. Thirty-nine patients with CD (19.4%) had stricturing phenotype. Of the patients with UC and IBDU, 39 (18.4%) suffered from pancolitis and 61 (29%) from proctitis. Severe endoscopic lesions at diagnosis were seen in 119 patients (28.8%, 68 CD, 49 UC, and 2 IBDU), whereas 98 patients (23.7%) had severe histological disease activity. Thirteen patients (3.1%, 10 CD and 3 UC) had extraintestinal manifestations at diagnosis. Twenty-three patients (5.6%, 20 CD and 3 UC) had fistula at diagnosis. CONCLUSIONS In this cohort, 31% of the patients with CD had complicated disease at diagnosis, 39% had ileocolonic disease, 9.5% had perianal disease, and in 4% the upper gastrointestinal tract was involved. Most patients with UC suffered from left-sided colitis (51%). Severe endoscopic lesions were reported in 34% of the patients with CD and 26% of the patients with UC. Three percent of the patients with IBD had extraintestinal manifestations.

Abstract
Standardized mortality rates in ulcerative colitis (UC) are no different than that in the general population. Patients who are older and have more comorbidities have increased mortality. Emergent colectomy still carries 30-day mortality rates of approximately 5%. In more recent studies, UC surgery rates at 10 years from diagnosis are nearly 3% in Hungary, <10% in referral center studies from Asia, approximately 10% in Norway, the European Cohort Study of Inflammatory Bowel Diseases and Manitoba, Canada, and nearly 17% in Olmsted County, Minnesota. These rates are for the most part lower than reported colectomy rates from studies completed before 1990. Short-term colectomy rates in severe hospitalized UC have remained stable at 27% for several years. Generally, children seem to have higher rates of extensive colitis at diagnosis than adults. There also seems to be higher rates of colectomy in children than in adults (i.e., at least 20% at 10 years), and perhaps, this reflects a higher rate of extensive disease. Acute severe colitis in patients with UC still represents a condition with a high early colectomy rate and a measurable mortality rate.

Abstract
BACKGROUND Data from the northern hemisphere suggest that patients with ulcerative colitis (UC) have similar survival to the general population, whereas mortality in Crohn's disease (CD) is increased by up to 50%. There is a paucity of data from the southern hemisphere, especially in Australia. METHODS A prevalence cohort (1977-1992) of patients with inflammatory bowel disease (IBD) diagnosed after 1970 was studied. Survival status data and causes of death up to December 2010 were extracted from the National Death Index. Relative survival analysis was carried out separately for men and women. RESULTS Of 816 cases (384 men, 432 women; 373 CD, 401 UC, 42 indeterminate colitis), 211 (25.9%) had died by December 2010. Median follow-up was 22.2 years. Relative survival of all patients with IBD was not significantly different from the general population at 10, 20, and 30 years of follow-up. Separate analyses of survival in CD and UC also showed no differences from the general population. There was no difference in survival between patients diagnosed earlier (1971-1979) or later (1980-1992). At least 17% of the deaths were caused by IBD. Fatal cholangiocarcinomas were more common in IBD (P < 0.001), and fatal colorectal cancers more common in UC (P = 0.047). CONCLUSIONS In Australia, IBD patient survival is similar to the general population. In contrast to data from Europe and North America, survival in CD is not diminished in Australia. IBD caused direct mortality in 17%, especially as biliary and colorectal cancers are significant causes of death.

Abstract
BACKGROUND Sexuality is important when assessing quality of life (QoL), which is often disturbed in inflammatory bowel disease (IBD). However, sexuality is not addressed in most QoL questionnaires. AIMS To evaluate the prevalence and predisposing factors of sexual dysfunction among IBD patients, and their own perception. METHODS A postal survey was conducted in IBD patients 25-65 years of age from two tertiary centres. Patients were asked to provide a control of the same gender and age without IBD. The questionnaire assessed patient perception of the impact of IBD on their sexuality, and also allowed calculation of the Erectile Function International Index or the Female Sexual Function Index. RESULTS A total of 355 patients and 200 controls were available for the final analysis. Both groups were comparable except for a higher proportion of individuals who had been treated for depression among patients. Half of the female and one-third of the male patients considered that both sexual desire and satisfaction worsened after IBD diagnosis. As compared to controls, both men and women with IBD showed significantly lower scores in sexual function indexes, but a higher prevalence of sexual dysfunction was only noticed among women. Independent predictors of sexual dysfunction among IBD patients were the use of corticosteroids in women, and the use of biological agents, depression and diabetes in men. CONCLUSIONS Sexuality is often disturbed in IBD patients, particularly among women. Many factors seem to contribute to worsened intimacy. Sexuality should be considered when QoL is assessed in these patients.

Abstract
Inflammatory bowel diseases (IBD) are chronic disabling gastrointestinal disorders impacting every aspect of the affected individual's life and account for substantial costs to the health care system and society. New epidemiological data suggest that the incidence and prevalence of the diseases are increasing and medical therapy and disease management have changed significantly in the last decade. An estimated 2.5-3 million people in Europe are affected by IBD, with a direct healthcare cost of 4.6-5.6 bn Euros/year. Therefore, the aim of this review is to describe the burden of IBD in Europe by discussing the latest epidemiological data, the disease course and risk for surgery and hospitalization, mortality and cancer risks, as well as the economic aspects, patients' disability and work impairment.

Abstract
BACKGROUND Evidence regarding all-cause and cause-specific mortality in inflammatory bowel disease (IBD) is conflicting, and debate exists over appropriate study design to examine these important outcomes. We conducted a comprehensive meta-analysis of all-cause and cause-specific mortality in both Crohn's disease (CD) and ulcerative colitis (UC), and additionally examined various effects of study design on this outcome. METHODS A systematic search of PubMed and EMBASE was conducted to identify studies examining mortality rates relative to the general population. Pooled summary standardized mortality ratios (SMR) were calculated using random effect models. RESULTS Overall, 35 original articles fulfilled the inclusion and exclusion criteria, reporting all-cause mortality SMRs varying from 0.44 to 7.14 for UC and 0.71 to 3.20 for CD. The all-cause mortality summary SMR for inception cohort and population cohort UC studies was 1.19 (95% confidence interval, 1.06-1.35). The all-cause mortality summary SMR for inception cohort and population cohort CD studies was 1.38 (95% confidence interval, 1.23-1.55). Mortality from colorectal cancer, pulmonary disease, and nonalcoholic liver disease was increased, whereas mortality from cardiovascular disease was decreased. CONCLUSIONS Patients with UC and CD have higher rates of death from all causes, colorectal-cancer, pulmonary disease, and nonalcoholic liver disease.

Abstract
The colony stimulating factor-1 (CSF-1) receptor (CSF-1R) directly regulates the development of Paneth cells (PC) and influences proliferation and cell fate in the small intestine (SI). In the present study, we have examined the role of CSF-1 and the CSF-1R in the large intestine, which lacks PC, in the steady state and in response to acute inflammation induced by dextran sulfate sodium (DSS). As previously shown in mouse, immunohistochemical (IHC) analysis of CSF-1R expression showed that the receptor is baso-laterally expressed on epithelial cells of human colonic crypts, indicating that this expression pattern is shared between species. Colons from Csf1r null and Csf1(op/op) mice were isolated and sectioned for IHC identification of enterocytes, enteroendocrine cells, goblet cells and proliferating cells. Both Csf1r(-/-) and Csf1(op/op) mice were found to have colon defects in enterocytes and enteroendocrine cell fate, with excessive goblet cell staining and reduced cell proliferation. In addition, the gene expression profiles of the cell cycle genes, cyclinD1, c-myc, c-fos, and c-myb were suppressed in Csf1r(-/-) colonic crypt, compared with those of WT mice and the expression of the stem cell marker gene Lgr5 was markedly reduced. However, analysis of the proliferative responses of immortalized mouse colon epithelial cells (lines; Immorto-5 and YAMC) indicated that CSF-1R is not a major regulator of colonocyte proliferation and that its effects on proliferation are indirect. In an examination of the acute inflammatory response, Csf1r(+/-) male mice were protected from the adverse affects of DSS-induced colitis compared with WT mice, while Csf1r(+/-) female mice were significantly less protected. These data indicate that CSF-1R signaling plays an important role in colon homeostasis and stem cell gene expression but that the receptor exacerbates the response to inflammatory challenge in male mice.

Abstract
INTRODUCTION Infliximab is registered for the treatment of moderate-to-severe active ulcerative colitis (UC) adult patients who have had an inadequate response, or are intolerant, or have medical contraindications to therapy including corticosteroids and 5-aminosalicylates or thiopurines (6-mercaptopurine [6-MP] or azathioprine [AZA]). The authors estimate the costs and effects and evaluate the cost-effectiveness of infliximab at the licensed dose of 5 mg/kg versus cyclosporine or surgery for the treatment of adult Dutch patients hospitalized with acute exacerbations of UC, refractory to intravenous steroids. METHOD An existing decision analytical model was updated to simulate disease progression of hospitalized UC patients in the Netherlands, refractory to intravenous corticosteroids, and to estimate the costs and benefits associated with infliximab compared to cyclosporine and surgery over a 1-year time horizon. Colectomy rates were derived from infliximab and cyclosporine randomized trials and synthesized using multiple treatment comparison methods. The utility estimates associated with health states of ulcerative colitis patients were obtained from the literature. Resource use and drug use frequencies as well as unit costs were obtained from Dutch sources. The primary effectiveness measure used in the analysis was quality-adjusted life years (QALYs). RESULTS For a typical UC patient with body weight of 70 kg, the costs of treatment with infliximab, cyclosporine, and surgery over a 1-year treatment period were €17,062, €14,784, €13,979, respectively. The associated numbers of QALYs were 0.80, 0.70, and 0.58 for infliximab, cyclosporine, and surgery respectively. The incremental cost-effectiveness ratio for infliximab was €24,277 per QALY gained compared to cyclosporine, and €14,639 per QALY gained compared to surgery. CONCLUSIONS Infliximab induction regimen appears to be a cost-effective treatment option in comparison to cyclosporine and surgery for hospitalized patients with acute exacerbations of UC, refractory to intravenous corticosteroids in the Netherlands.

Abstract
OBJECTIVE To examine sex differences in medical therapy and clinical outcomes in pediatric patients with inflammatory bowel disease (IBD). METHODS We performed a cross-sectional analysis of children with Crohn disease (CD) and ulcerative colitis (UC) using data from the ImproveCareNow Network collected between May 2007 and May 2010. Clinical remission, disease severity, body mass index (BMI) z scores, normal height velocity, and medication use were analyzed by sex and age. RESULTS One thousand four hundred nine patients were included (993 had CD and 416 had UC). No significant sex differences were found in disease severity, BMI, height velocity, or use of medications. Further analysis of combination therapy with infliximab + 6-mercaptopurine/azathioprine and infliximab + methotrexate also did not reveal any differences. No sex differences were found after mediation use was stratified by age (those younger than 13 years and those 13 years old or older). CONCLUSIONS In this sample of CD and UC pediatric patients, no significant sex differences were found in disease severity, BMI, height velocity, or medication use. Our data do not support the use of sex as a major factor in patient risk stratification for children with IBD. In addition, despite concerns for sex-specific complications of some medications, our analysis did not suggest any sex differences in medication use.

Abstract
Ulcerative colitis (UC) and Crohn's disease (CD) may directly result in morbidity and rarely mortality from complications such as colorectal cancer or sepsis. Mortality rates compared with the matched general population, measured by standardized mortality ratio, may therefore be increased. This review examines the evidence derived from cohort- and population-based mortality studies. In CD the majority of studies and two meta-analyses demonstrated increased standardized mortality ratios of ≈ 1.5-fold, especially for those diagnosed at younger ages and requiring extensive or multiple resection surgery. In UC mortality rates are similar to those of the general population in most studies and a meta-analysis. Proctocolectomy removes the inflammatory burden of UC and can manage colorectal dysplasia but may result in perioperative complications. There is no clear temporal trend of improvement in survival for either CD or UC. Few data are available from countries outside Europe and North America, so geographical influences remain largely unknown.

Abstract
BACKGROUND The aim of this study was to examine the influence of age at diagnosis and sex on the clinical course and long-term prognosis of intestinal Behcet's disease (BD). METHODS We reviewed the medical records of 291 patients with intestinal BD who underwent regular follow-up at a single tertiary academic medical center. The patients were divided into two groups according to their age at diagnosis of intestinal BD or sex. The cumulative probabilities of operation, admission, corticosteroid use, and immunosuppressant use after diagnosis were analyzed using the Kaplan-Meier method and a log-rank test. RESULTS Of the 291 patients, 154 (52.9%) were diagnosed with intestinal BD when younger than 40 years old, and 132 (45.4%) were male. Younger age at diagnosis was associated with a higher leukocyte count, C-reactive protein (CRP) level, and disease activity index for intestinal BD, and with a greater prevalence of volcano-shaped ulcers and a definite diagnostic subtype. Moreover, the cumulative probabilities of operation, admission, and corticosteroid use were significantly higher in the younger group. Male sex was associated with a higher CRP level and a greater prevalence of volcano-shaped ulcers. However, there were no significant differences in cumulative probabilities of operation, admission, corticosteroid use, and immunosuppressant use according to sex. CONCLUSIONS In intestinal BD, younger age at diagnosis is associated with a more severe clinical course and a poorer prognosis. However, although some clinical manifestations at initial diagnosis tend to be more severe in male patients, clinical outcomes do not differ significantly according to sex.

Abstract
The authors review the clinical outcome in patients with Crohn’s disease (CD) based on studies describing the natural course of the disease. Population-based studies have demonstrated that the incidence rates and prevalence rates for CD have increased since the mid-1970s. The authors search for English language articles from 1980 until 2011. Geographical variations, incidence, prevalence, smoking habits, sex, mortality and medications are investigated. An increasing incidence and prevalence of CD have been found over the last three decades. The disease seems to be most common in northern Europe and North America, but is probably increasing also in Asia and Africa. Smoking is associated with an increased risk of developing CD. Age < 40 at diagnosis, penetrating/stricturing complications, need for systemic steroids, and disease location in terminal ileum are factors associated with higher relapse rates. A slight predominance of women diagnosed with CD has been found. Ileocecal resection is the most commonly performed surgical procedure, and within the first five years after the diagnosis about one third of the patients have had intestinal surgery. Smoking is associated with a worse clinical course and with increased risk of flare-ups. In most studies the overall mortality is comparable to the background population. To date, the most effective treatment options in acute flares are glucocorticosteroids and tumor necrosis factor (TNF)-α- blockers. Azathioprine/methotrexate and TNF-α-blockers are effective in maintaining remission.
