Thromboembolic events and cardiovascular mortality in inflammatory bowel diseases: a meta-analysis of observational studies. J Crohns Colitis 2014; 8:469-79. [PMID: 24183231 DOI: 10.1016/j.crohns.2013.09.021] [Citation(s) in RCA: 131] [Impact Index Per Article: 13.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2013] [Revised: 09/22/2013] [Accepted: 09/24/2013] [Indexed: 02/08/2023]
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
BACKGROUND Patients with ulcerative colitis (UC) have an increased risk of developing colorectal cancer (CRC); however, the magnitude of this effect is open to debate. AIM To assess the risk of CRC in UC patients by systematic review and meta-analysis. METHODS A systematic literature search was performed up to November 2013. We selected studies describing the incidence and prevalence of CRC in patients with UC. Articles were assessed for quality using the Newcastle-Ottawa Scale. Cumulative incidence and incidence rates of CRC were combined and analysed using the generic inverse variance method. Sub-analyses were performed to identify factors associated with an increased risk of developing CRC. RESULTS A total of 81 studies (181 923 patients) met the inclusion criteria. The incidence rate of CRC in patients with UC was 1.58 per 1000 patient-years (py) [95% confidence interval (CI), 1.39–1.76]. Results were heterogeneous (I2 = 81–89%). The incidence rate was 4.02/1000 py (95%CI = 2.74–5.31) in studies that only included patients with extensive colitis, and 1.24/1000 py (95%CI = 1.01–1.47) in population-based studies. The incidence rate was 0.91/1000 py (95%CI = 0.61–1.2) in the first decade of disease, 4.07/1000 py (95%CI = 2.58–5.56) in the second, and 4.55/1000 py (95%CI = 2.64–6.46) in the third. The incidence rate decreased from 4.29/1000 py in the studies published in the 1950s to 1.21/1000 py in studies published in the last decade. CONCLUSIONS The risk of patients with ulcerative colitis developing colorectal cancer has decreased steadily over the last six decades, but the extent and duration of the disease increase this risk.

Abstract
AIM: To clarify the impact of cytomegalovirus (CMV) activation and antiviral therapy based on CMV antigen status on the long-term clinical course of ulcerative colitis (UC) patients.
METHODS: UC patients with flare-up were divided into CMV-positive and -negative groups according to the CMV antigenemia assay. The main treatment strategy provided for the patients in the CMV-positive group comprised a dose reduction of corticosteroids and administration of ganciclovir.
RESULTS: The median number of days to initial remission was significantly greater for the patients in the CMV-positive group (21 d vs 16 d, P = 0.009). However, the relapse rate after remission and colectomy rate during more than 30 mo of observation did not differ between the two groups. Multivariate analysis revealed that administration of ganciclovir was the only independent factor for avoiding colectomy in patients of the CMV-positive group.
CONCLUSION: CMV antigen status did not significantly affect the long-term prognosis in UC patients under treatment with appropriate antiviral therapy.

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
Patients with inflammatory bowel disease are susceptible to complications from pharmacologic treatment of their disease. Tumor necrosis factor (TNF)-α inhibitors are being used increasingly in the treatment of inflammatory bowel disease and can be associated with adverse events, including common infections, and rarely the development of serious life-threatening opportunistic infections. TNF-α inhibitors have the ability to prevent an effective patient granulomatous response, and this may be associated with an increased risk of developing mycobacterial and certain fungal infections, including histoplasmosis, blastomycosis, and coccidioidomycosis, endemic in several parts of the United States. The concern for invasive fungal infection was realized during clinical trials and further demonstrated after the marketing of TNF-α inhibitors. Because of this awareness, the Food and Drug Administration developed an adverse event-reporting system to capture cases of infections associated with the use of TNF-α inhibitors. These opportunistic fungi have a great degree of regional variability, and it has been very difficult to quantify the incidence of infection in patients treated with TNF-α inhibitors. Currently, there are no formal guidelines regarding the use of TNF-α inhibitors and these fungal infections. Considering that gastroenterologists have embraced the use TNF-α inhibitors as a valuable armamentarium in the treatment of inflammatory bowel disease, they must be aware of therapy-related infectious complications, including appropriate diagnostic, therapeutic, and preventive strategies. In this article, we explore the association of these fungal entities in relation to the TNF-α inhibitor therapy by considering information provided in the gastroenterology, infectious diseases, rheumatology, and transplant literature. Finally, we provide some recommendations on diagnosis and treatment.

Abstract
BACKGROUND Inflammatory bowel disease, especially ulcerative colitis, is increasing in many "non-Western" countries, including Sri Lanka. The aim was to evaluate long-term outcomes of ulcerative colitis in a Sri Lankan population. METHODS A retrospective cohort study was conducted at the gastroenterology clinics of the Colombo North Teaching Hospital, Ragama and the National Hospital of Sri Lanka, Colombo; the two major referral centers for ulcerative colitis. All cases had histological confirmation of ulcerative colitis. Three outcomes: colectomy, development of colorectal carcinoma, and death were assessed. Patients not attending the clinic during the previous 4 weeks, or their families, were contacted to obtain clinical details and survival status. In those who had died, the cause of death was confirmed from clinical records and death certificates. RESULTS Details of 348/425 (81.9%) patients with ulcerative colitis (mean age 45.6 [standard deviation {SD} 14.3] years, male/female ratio = 1.00:1.03) were available. The mean follow-up was 6.8 (SD 6.5) years. The cumulative colectomy rates at 1, 5, 10, and 15 years were 1.5%, 4.0%, 5.5%, and 9.3% respectively. The cumulative probability of colorectal cancer in this cohort after 10 and 15 years was 0.47% and 2.36% respectively. The cumulative survival rate after 1, 5, 10, and 15 years was 99.7%, 98.9%, 98.1%, and 94.5% respectively. Patients with pancolitis were more likely to have disease-related death (P = 0.05). Multivariate analysis (Cox proportional hazards model) showed that an older age at diagnosis was associated with long-term mortality (hazard ratio, 1.11; P = 0.001). CONCLUSION In this cohort, colectomy, colorectal carcinoma, and death rates were low, suggesting a relatively benign disease course for ulcerative colitis.

Abstract
BACKGROUND Little is known about environmental determinants of autoimmune diseases. OBJECTIVES We studied autoimmune diseases in relation to level of exposure to perfluorooctanoic acid (PFOA), which was introduced in the late 1940s and is now ubiquitous in the serum of residents of industrialized countries. METHODS In 2008-2011 we interviewed 32,254 U.S. adults with high serum PFOA serum levels (median, 28 ng/mL) associated with drinking contaminated water near a chemical plant. Disease history was assessed retrospectively from 1952 or birth (if later than 1952) until interview. Self-reported history of autoimmune disease was validated via medical records. Cumulative exposure to PFOA was derived from estimates of annual mean serum PFOA levels during follow-up, which were based on plant emissions, residential and work history, and a fate-transport model. Cox regression models were used to estimate associations between quartiles of cumulative PFOA serum levels and the incidence of autoimmune diseases with ≥ 50 validated cases, including ulcerative colitis (n = 151), Crohn's disease (n = 96), rheumatoid arthritis (n = 346), insulin-dependent diabetes (presumed to be type 1) (n = 160), lupus (n = 75), and multiple sclerosis (n = 98). RESULTS The incidence of ulcerative colitis was significantly increased in association with PFOA exposure, with adjusted rate ratios by quartile of exposure of 1.00 (referent), 1.76 (95% CI: 1.04, 2.99), 2.63 (95% CI: 1.56, 4.43), and 2.86 (95% CI: 1.65, 4.96) (ptrend < 0.0001). A prospective analysis of ulcerative colitis diagnosed after the baseline 2005-2006 survey (n = 29 cases) suggested a positive but non-monotonic trend (ptrend = 0.21). DISCUSSION To our knowledge, this is the first study of associations between this common environmental exposure and autoimmune diseases in humans. We found evidence that PFOA is associated with ulcerative colitis.

Abstract
AIM To evaluate the anti-inflammatory effect of antiplatelet agent, clopidogrel, in experimentally induced inflammatory bowel disease (IBD). MATERIALS AND METHODS TNBS induced Crohn's disease model and oxazolone induced ulcerative colitis model were used to evaluate the role of clopidogrel in IBD. Spargue Dawley female and Wistar male rats were used respectively. The colitis was induced by a single intra-colonic application of TNBS (0.25 ml, 120 mg/ml in 50% ethanol) and oxazolone (450 μl 5% oxazolone in 50% ethanol). Rats were divided into four groups (n=6) in each model namely normal control, sham control, test and standard group. Drug treatment was carried out for 21 days. After 21 days, animals were sacrificed and evaluated for weight change, colon mucosal damage index (CMDI), disease activity Index (DAI) and myeloperoxidase (MPO) activity. RESULTS Results showed that clopidogrel provided significant protection against mucosal damage in both the models of IBD. It significantly reduced (P<0.05) the decrease in body weight and CMDI, DAI and MPO scores. CONCLUSION The results indicate that clopidogrel may be effective in treatment of Crohn's disease and ulcerative colitis. Platelet inhibition may be one of the mechanism for effectiveness of clopidogrel in the treatment of IBD.

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
BACKGROUND & AIMS The relationship between inflammatory bowel disease (IBD) and the incidence and mortality of colorectal adenocarcinoma (CRC) has not been evaluated recently. METHODS We calculated the incidence and standardized incidence and mortality rate ratios of CRC among adult individuals with intact colons using Kaiser Permanente of Northern California's database of members with IBD and general membership data for the period of 1998 to June 2010 (data through 2008 were used to calculate mortality). We also evaluated trends in medication use and rates of cancer detection over time. RESULTS We identified 29 cancers among persons with Crohn's disease (CD) and 53 among persons with ulcerative colitis (UC). Overall, the incidence rates of cancer among individuals with CD, UC, or in the general membership were 75.0, 76.0, and 47.1, respectively, per 100,000 person-years. In the general population, the incidence of CRC was 21% higher in 2007-2010 than in 1998-2001 (P for trend, <.0001), coincident with the growth of CRC screening programs. The incidence of CRC among individuals with CD or UC was 60% higher than in the general population (95% confidence interval [CI] for CD, 20%-200%; 95% CI for UC, 30%-200%) and was stable over time (P for trend was as follows: CD, .98; UC, .40). During 1998-2008, the standardized mortality ratio for CRC in individuals with CD was 2.3 (95% CI, 1.6-3.0) and 2.0 in those with UC (95% CI, 1.3-2.7). Over the study period, anti-tumor necrosis factor agents replaced other therapies for CD and UC; the rate of colonoscopy increased by 33% among patients with CD and decreased by 9% in those with UC. CONCLUSIONS From 1998 to 2010, the incidence of CRC in patients with IBD was 60% higher than in the general population and essentially stable over time.

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 Pouchitis is the most common long-term complication in ulcerative colitis that follows restorative proctocolectomy. Clinical evidence suggests that dysbiosis plays a key role in its pathogenesis. METHODS Current literature on the topic was reviewed. A therapeutic approach was proposed based on the literature along with personal experience from the subspecialty Pouchitis Clinic. RESULTS Pouchitis represents a disease spectrum in the reservoir, with ranging etiopathogenesis, clinical phenotypes, disease courses and prognoses. Dysbiosis plays a critical role in disease initiation and progress, with antibiotic therapy as the mainstay for treatment. On the other hand, superimposed infection from pathogens contributes to flare-up of the disease. Pouchitis can progress into an 'IBD-like' condition, requiring anti-inflammatory, immunomodulator or even biological therapy. CONCLUSION Pouchitis represents a unique form of IBD. Investigation on the evolution from an antibiotic-responsive phenotype to chronic antibiotic-refractory pouchitis may shed some light on the pathogenesis and therapeutic targets of IBD.

Abstract
In the management of Crohn's disease, earlier aggressive treatment is becoming accepted as a strategy to prevent or retard progression to irreversible bowel damage. It is not yet clear, however, if this same concept should be applied to ulcerative colitis. Hence, we review herein the long-term structural and functional consequences of this latter disease. Disease progression in ulcerative colitis takes six principal forms: proximal extension, stricturing, pseudopolyposis, dysmotility, anorectal dysfunction, and impaired permeability. The precise incidence of these complications and the ability of earlier, more aggressive treatment to prevent them have yet to be determined.

Abstract
BACKGROUND Today we are observing an increasing incidence of ulcerative colitis associated with an improved survival of patients. AIM To analyse current rates, outcomes, and costs of inpatient care for ulcerative colitis patients of central Italy. METHODS The cohort included 644 ulcerative colitis patients, living in the Lazio region, with diagnosis made or confirmed by the staff of a single tertiary referral centre in Rome (1997-2006). Follow-up data on hospitalization rates, costs, and colectomy rates were collected from the Regional Hospital Information System. RESULTS Overall hospitalization rates were 3 times higher than those of the region's general population, reflecting excess admissions for digestive or infectious diseases (standardized hospitalizations rates for digestive-tract: 15.9; for infectious diseases: 3.5). The overall cumulative risk for colectomy was 7.5%. On the average, hospitalizations for ulcerative colitis lasted 10 days. The mean reimbursement for a ulcerative colitis-related hospitalization was EUR 5120 (€4609 for nonsurgical admissions, €8655 for surgical hospitalizations). CONCLUSION Ulcerative colitis patients are 3 times more likely to be hospitalized than the general population. Colectomy rates in Italian ulcerative colitis patients resemble those of northern Europe, but most hospital admissions are for diagnostic procedures or medical therapy. Hospitalizations are almost twice as long as those reported in the United States although their mean cost is considerably lower.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis has become the procedure of choice for the majority of patients with ulcerative colitis who require surgical treatment. Pouchitis, the most common long-term complication of the procedure, involves a spectrum of disease processes with heterogeneous risk factors, clinical features, disease courses and prognoses. In addition, clinical symptoms of pouchitis are not specific and often overlap with those of other inflammatory and functional pouch disorders, such as Crohn's disease of the pouch and irritable pouch syndrome. Pouchoscopy and biopsy, along with laboratory and radiographic evaluations, are often required for accurate diagnosis in patients with symptoms indicative of pouchitis. Dysbiosis has been implicated as a triggering factor for pouchitis, and concurrent infection with pathogens, such as Clostridium difficile, might contribute to disease relapse and exacerbation. Antibiotic therapy is the main treatment modality. However, the management of antibiotic-dependent and antibiotic-refractory pouchitis remains challenging. Secondary causes of pouchitis, such as ischaemia, NSAID use, the presence of concurrent primary sclerosing cholangitis and other systemic immune-mediated disorders, should be evaluated and properly managed.

Abstract
Crohn's disease is an inflammatory bowel disease associated with a variety of systemic manifestations, including large and small airway involvement. The latter is most often a subclinical one, and requires expensive and invasive diagnostic approaches. Nitric oxide (NO) can be detected non-invasively in the exhaled air (eNO) and be considered as a surrogate marker of airway inflammation. eNO tested at multiple expiratory flows can be used to distinguish the alveolar concentration of NO (CalvNO) from the total amount of fractional eNO (FeNO). The aim of our study is to compare FeNO and concentration of alveolar nitric oxide (CalvNO) levels and to assess their relationship with pulmonary involvement in Crohn's patients differing in clinical stage and therapeutic regimens versus a group of healthy subjects. Thirty Crohn's patients not showing clinical evidence of pulmonary diseases and 21 non-smoking, non-atopic healthy controls were enrolled. FeNO (14.9±10.2 ppb vs 10.1±6.3 ppb, p=0.049) and CalvNO (4.4±2.2 ppb vs 2.6±1.9; p=0.006) values were found to be significantly higher in Crohn's patients than in healthy controls. Both FeNO and CalvNO correlated positively with the Crohn's Disease Activity Index. In conclusion, our results for FeNO and CalvNO confirm the presence of subclinical pulmonary involvement in Crohn's disease. eNO measurement may be of clinical value in the follow-up of Crohn's patients.

Abstract
BACKGROUND Ulcerative colitis (UC) has a large impact on patients' lives. Clinical course studies of population-based cohorts contribute to our understanding of the disease as it progresses. We reviewed the clinical course of UC as reported in adult population-based longitudinal cohort studies. METHODS A MEDLINE literature search to identify all adult population-based studies published up to June 2010 with data on the clinical course of UC was performed. Demographic and clinical data were reviewed. RESULTS Twenty-two studies reporting data from seven prospective longitudinal cohorts were identified. Extension from initial location varied from 10%-19% of the patients after 5 years of disease and from 11%-28% after 10 years in two of the cohorts. Disease activity appeared to improve over the disease course. The majority of patients had relapses in the first years of disease. The cumulative relapse rate varied from 67%-83% after 10 years of disease. From 1962-2004 a decreasing trend in the proportion of colectomies was observed. Most colectomies were performed during the first 2 years of disease and in patients with pancolitis. Salycilates were the most consumed medication followed by systemic steroids, immunosuppressors, and antitumor necrosis factors, with the latter two showing a substantial increased intake over time. Mortality increased with disease duration. CONCLUSIONS This review shows how the clinical course of UC has changed over time and alerts to the need for more prospective cohort studies to evaluate long-term outcomes especially to study the impact of biologic agents on UC.

Abstract
BACKGROUND & AIMS Patients with chronic inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus, and psoriasis have an increased risk of myocardial infarction (MI). Studies of the risk of MI among patients with inflammatory bowel disease have provided inconsistent results. We aimed to determine the risk of first-time acute MI in patients with ulcerative colitis (UC) or Crohn's disease (CD) compared with patients from general practice. METHODS We conducted 2 retrospective cohort studies using the General Practice Research Database. A total of 15,498 UC patients were matched to 144,605 general practice patients (for age, sex, year of enrollment in the General Practice Research Database, and general practice of attendance) and were followed up for a mean of 4.7 years; 9829 CD patients were matched to 92,987 patients from general practice and followed up for a mean of 4.5 years. Univariable and multivariable Cox regression analyses were adjusted for age, sex, history of hypertension, diabetes mellitus, hypercholesterolemia, smoking status, body mass index, and aspirin use for each cohort. RESULTS Patients with UC had a significantly increased risk of first-time acute MI compared with patients from general practice in unadjusted, but not adjusted, analysis (adjusted hazard ratio, 1.11; 95% confidence interval, 0.98-1.27). Patients with CD did not have an increased risk of MI in either unadjusted or adjusted analyses (adjusted hazard ratio, 1.09; 95% confidence interval, 0.89-1.34). CONCLUSIONS Unlike some other chronic inflammatory diseases, inflammatory bowel disease is not associated with an increased risk of MI.

Abstract
Patients with inflammatory bowel disease (IBD) can be affected by other unrelated diseases. These are called comorbid conditions, and can include any secondary health problem that affects a person suffering from a primary or main disease, and which is neither linked physiopathologically to the primary condition, nor is it due to the treatments used for the primary condition or to its long-term anatomical or physiological consequences. Different comorbid conditions, as well as their influence on IBD, are discussed.

Abstract
One of the most serious complications of ulcerative colitis is the development of colorectal cancer. Screening patients with ulcerative colitis by standard histological examination of random intestinal biopsy samples might be inefficient as a method of cancer surveillance. This Review focuses on the current understanding of the pathogenesis of ulcerative colitis-associated colorectal cancer and how this knowledge can be transferred into patient management to assist clinicians and pathologists in identifying patients with ulcerative colitis who have an increased risk of colorectal cancer. Inflammation-driven mechanisms of DNA damage, including the generation and effects of reactive oxygen species, microsatellite instability, telomere shortening and chromosomal instability, are reviewed, as are the molecular responses to genomic stress. We also discuss how these mechanisms can be translated into usable biomarkers. Although progress has been made in the understanding of inflammation-driven carcinogenesis, markers based on these findings possess insufficient sensitivity or specificity to be usable as reliable biomarkers for risk of colorectal cancer development in patients with ulcerative colitis. However, screening for mutations in p53 could be relevant in the surveillance of patients with ulcerative colitis. Several other new biomarkers, including senescence markers and α-methylacyl-CoA-racemase, might be future candidates for preneoplastic markers in ulcerative colitis.

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

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease
(IBD) associated with multiple colonic and extraintestinal
complications, the most severe being the development of colorectal
cancer (CRC). Compared to the general population, there is an
increased risk of CRC associated with UC. Although the
pathogenesis of CRC in UC is unknown, most studies have linked it
to long-standing inflammation as well as other risk factors such
as duration of disease, extent of inflammation, family history of
CRC, and coexisting conditions such as primary sclerosing
cholangitis (PSC). UC is a life-long disease for which patients
enter a vigilant screening program which includes surveillance
colonoscopy to promote early detection of CRC yet some
controversies exist regarding the cost effectiveness of
surveillance colonoscopy and improving survival. Newer modalities
such as chromoendoscopy, narrow band imaging, high definition
colonoscopy, and confocal microscopy have aided in developing a
more targeted approach for early detection of dysplasia in
surveillance colonoscopy. This review focuses on the role of
chronic colonic inflammation and dysplasia in development of
UC-associated CRC and current methods of screening, detection,
chemoprevention, and treatment of UC-associated CRC.

Abstract
BACKGROUND/AIM Metabolic syndrome (MetS) is a clinical condition characterized by central obesity, elevated triglycerides, low-high density lipoproteins, impaired fasting glucose, and hypertension. There is insufficient data on the prevalence of MetS in patients with inflammatory bowel disease (IBD). This study sought to determine the prevalence of MetS in a Turkish cohort of patients with IBD and the association between insulin resistance (IR) and the MetS parameters, in this population. PATIENTS AND METHODS A total of 177 patients over 18 years of age (62 with Crohn's disease (CD) and 115 with ulcerative colitis (UC)) were enrolled in the study. The presence of at least three criteria of the International Diabetes Federation (IDF) was accepted for the diagnosis of MetS. The Homeostasis Model Assessment (HOMA) was used to determine IR. HOMA values < 1 were considered normal and values > 2.5 indicated a high probability of IR. RESULTS MetS frequency was higher in patients n=34 (29.5%) with UC than in patients n=11 (17.7%) with CD (P < 0.01). MetS was detected in 12 of the 117 patients (10.3%) with IBD, under 45 years of age, and in 33 of 60 patients (55%) over 45 years of age. HOMA value in n=31 patients (27%) with UC was > 2.5. Body mass index, insulin (P < 0.001), waist circumference, fasting plasma glucose, leukocyte count (P < 0.01), triglycerides, C-reactive protein, and uric acid values (P < 0.05) were significantly higher in UC patients with IR than those without IR. CONCLUSION Frequent occurrence of MS with increasing age in IBD, particularly in UC, showed the importance of early diagnosis and treatment of cardiovascular disease risk factors in the long-term follow-up of these diseases.

Abstract
BACKGROUND The risk of suicide is increased among people with inflammatory bowel disease (IBD); however, most of the evidence regarding this association comes from studies of all-cause mortality, with small numbers of people who have committed suicide, or from clinical case reports. The current study examined the association between the two forms of IBD: Crohn's disease (CD) and ulcerative colitis (UC), and completed suicide in a population-based sample. METHODS Data for this nested case-control study were obtained from the Danish national healthcare and social registries. We included 27,053 cases who completed suicide between January 1, 1981, and December 31, 2006. Controls were selected from the general population and matched to cases on gender, date of birth, and calendar time (n = 551,060). RESULTS There was an increased rate of suicide among participants with both CD (odds ratio [OR] = 1.6, 95% confidence interval [CI]: 1.1, 2.3) and UC (OR = 1.9, 95% CI: 1.4, 2.4), when adjusting for the matched factors and identified confounders. CONCLUSIONS The current study suggests that physicians treating IBD patients should be vigilant about expressions of suicidal ideation or signs and symptoms of self-harm.

Abstract
Patients with immune-mediated inflammatory diseases (IMID) such as RA, IBD or psoriasis, are at increased risk of infection, partially because of the disease itself, but mostly because of treatment with immunomodulatory or immunosuppressive drugs. In spite of their elevated risk for vaccine-preventable disease, vaccination coverage in IMID patients is surprisingly low. This review summarizes current literature data on vaccine safety and efficacy in IMID patients treated with immunosuppressive or immunomodulatory drugs and formulates best-practice recommendations on vaccination in this population. Especially in the current era of biological therapies, including TNF-blocking agents, special consideration should be given to vaccination strategies in IMID patients. Clinical evidence indicates that immunization of IMID patients does not increase clinical or laboratory parameters of disease activity. Live vaccines are contraindicated in immunocompromized individuals, but non-live vaccines can safely be given. Although the reduced quality of the immune response in patients under immunotherapy may have a negative impact on vaccination efficacy in this population, adequate humoral response to vaccination in IMID patients has been demonstrated for hepatitis B, influenza and pneumococcal vaccination. Vaccination status is best checked and updated before the start of immunomodulatory therapy: live vaccines are not contraindicated at that time and inactivated vaccines elicit an optimal immune response in immunocompetent individuals.

Prevalence of metabolic syndrome is comparable between inflammatory bowel disease patients and the general population. J Gastroenterol 2010; 45:1008-13. [PMID: 20414788 DOI: 10.1007/s00535-010-0247-z] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2009] [Accepted: 03/25/2010] [Indexed: 02/04/2023]
Abstract
BACKGROUND Metabolic syndrome (MS) is associated with an increased risk of cardiovascular disease. However, its prevalence in inflammatory bowel disease (IBD) patients remains largely unknown. This study was planned to determine the prevalence of MS in Japanese IBD patients. METHODS The prevalence of MS among outpatients with IBD aged 18 or older was studied using the modified National Cholesterol Education Program Adult Treatment Panel III definition. RESULTS A total of 107 quiescent IBD patients, including 76 ulcerative colitis (UC) patients and 31 Crohn's disease (CD) patients, were studied. Sufficient data were collected from a total of 102 patients. Prevalence of MS was significantly higher in UC (23.0%) patients compared to CD patients (7.1%). MS prevalence was substantially higher among male IBD patients (21.1%) compared to female IBD patients (12.9%), particularly in patients over 30 years of age. No difference was observed in the prevalence of MS between our IBD cohort and the general population in both males and females aged 40 years and older (P = 0.707 in males, P = 0.328 in females). IBD patients with MS were also older than those without (50.2 ± 15.0 vs. 38.0 ± 11.9 years, P = 0.013). In a logistic regression analysis, age was the statistically significant predictor of MS among IBD patients. The odds ratio (95% confidence interval) was 1.064 (1.017-1.114). CONCLUSIONS Prevalence of metabolic syndrome in our IBD patients was comparable to that of the general population. Because age was the independent risk factor for developing MS, evaluation for MS is needed for elderly IBD patients.

Abstract
BACKGROUND Computerized tomography enterography (CTE), gastrograffin enema (GGE), magnetic resonance imaging (MRI), and pouch endoscopy (PES) have commonly been used to assess ileal pouch disorders. However, their diagnostic utility has not been systematically evaluated. The aims of this study were to compare these imaging techniques to each other and to optimize diagnosis of pouch disorders by using a combination of these diagnostic modalities. METHODS Clinical data of patients from the Pouchitis Clinic from 2003 to 2008 who had a PES and at least 1 additional imaging modalities (CTE, GGE, or MRI) used for evaluation of ileal pouch disorders were retrospectively evaluated. We analyzed the accuracy, sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) with which these tests were able diagnose pouch inlet and distal small bowel and pouch outlet strictures, pouch fistulas, sinuses, and leaks. Subsequently, accuracy was recalculated by combining 2 imaging modalities to see if this could enhance accuracy. RESULTS A total of 66 patients underwent evaluation with PES and 1 other imaging modality as follows: PES + CTE (n = 23), PES + GGE (n = 34), and PES + MRI (n = 26). The mean age was 41.5 +/- 14.5 years, with 28 being female (42.4%). Sixty patients (90.9%) had J pouches and 59 (89.4%) had a preoperative diagnosis of ulcerative colitis. Overall, CTE, GGE, MRI, and PES all had reasonable accuracy for the diagnosis of small bowel and inlet strictures (73.9%-95.4%), outlet strictures (87.9%-92.3%), fistula (76.9%-84.8%), sinus (68.0%-93.9%), and pouch leak (83-93.9%). CTE had the lowest accuracy for small bowel and inlet strictures (73.9%) and MRI had the lowest accuracy for pouch sinus (68.0%). Combining 2 imaging tests can increase the accuracy of diagnosis to 100% for strictures, fistulas, sinus, and pouch leaks. CONCLUSIONS CTE, GGE, MRI, and PES offer complementary information on disorders of the pouch and the combination of these tests increases diagnostic accuracy for complex cases.

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

Patients with late-adult-onset ulcerative colitis have better outcomes than those with early onset disease. Clin Gastroenterol Hepatol 2010; 8:682-687.e1.

Abstract
BACKGROUND & AIMS The influence of age on the presentation, clinical course, and therapeutic response of patients with adult-onset ulcerative colitis (UC) is understudied. Given potential age-related differences in risk factors and immune function, we sought to determine if disease behavior or clinical outcomes differed between patients diagnosed with UC in later versus earlier stages of adulthood. METHODS We performed a retrospective cohort study of 295 patients with UC seen at a tertiary care center from 2001 to 2008. Adult subjects newly diagnosed with UC between the ages of 18 and 30 years were defined as early onset, those newly diagnosed at age 50 or older were defined as late onset. The 2 groups were analyzed for differences in medication use and clinical end points, including disease extent, severity at the time of diagnosis, and steroid-free clinical remission at 1 year after disease onset. RESULTS Disease extent and symptom severity were similar between groups at the time of diagnosis. One year after diagnosis, more patients in the late-onset group achieved steroid-free clinical remission (64% vs 49%; P = .01). Among those who required systemic steroid therapy, more late-onset patients achieved steroid-free remission by 1 year (50% vs 32%; P = .01). Former smoking status was a more common risk factor in the late-onset cohort (P < .001), whereas more early onset patients had a positive family history (P = .008). CONCLUSIONS Patients with early and late-adult-onset UC have similar initial clinical presentations, but differ in disease risk factors. Late-onset patients have better responses to therapy 1 year after diagnosis.

Abstract
BACKGROUND The aim was to evaluate overall and disease-specific mortality in a population-based inflammatory bowel disease (IBD) cohort in the Netherlands, as well as risk factors for mortality. METHODS IBD patients diagnosed between 1 January 1991 and 1 January 2003 were included. Standardized mortality ratios (SMRs) were calculated overall and with regard to causes of death, gender, as well as age, phenotype, smoking status at diagnosis, and medication use. RESULTS At the censoring date, 72 out of 1187 patients had died (21 Crohn's disease [CD], 47 ulcerative colitis [UC], and 4 indeterminate colitis [IC] patients). The SMR (95% confidence interval [CI]) was 1.1 (0.7-1.6) for CD, 0.9 (0.7-1.2) for UC and 0.7 (0.2-1.7) for IC. Disease-specific mortality risk was significantly increased for gastrointestinal (GI) causes of death both in CD (SMR 7.5, 95% CI: 2.8-16.4) and UC (SMR 3.4, 95% CI: 1.4-7.0); in CD patients, especially in patients <40 years of age at diagnosis. For UC, an increased SMR was noted in female patients and in patients <19 years and >80 years at diagnosis. In contrast, UC patients had a decreased mortality risk from cancer (SMR 0.5, 95% CI; 0.2-0.9). CONCLUSIONS In this population-based IBD study, mortality in CD, UC, and IC was comparable to the background population. The increased mortality risk for GI causes might reflect complicated disease course, with young and elderly patients at diagnosis needing intensive follow-up. Caution in interpreting the finding on mortality risk from cancer is needed as follow-up was probably to short to observe IBD-related cancers.

Abstract
The article summarizes the current knowledge on the pathogenesis, clinical aspects and treatment of bone problems in the major inflammatory bowel diseases (Crohn's disease and ulcerative colitis) and celiac disease. It presents the physiological relationship between intestine and bone as well as the alterations determined by disease-disrupted intestinal integrity. Two hypotheses about the pathogenetic mechanisms of bone metabolism derangements and bone loss are discussed: the classical one, that indicates calcium malabsorption as the main culprit, and the new one, that emphasizes the role of inflammation. The article summarizes the available epidemiological data about osteopenia/osteoporosis and fragility fractures in these chronic intestinal diseases and presents the state-of-the-art treatment options.

Abstract
BACKGROUND Pulmonary involvement due to inflammatory bowel disease (IBD) is frequent when evaluating a patient with IBD and pulmonary involvement remains complicated. Most of the patients are asymptomatic and the methods used are mostly invasive or expensive procedures. The aim of this prospective study is to evaluate the value of the fractional exhaled nitric oxide (FE(NO)) level for the diagnosis of pulmonary involvement due to IBD and to investigate any correlation between FE(NO) level and disease activity. METHODS Thirty-three nonsmoker patients with IBD (25 ulcerative colitis [UC] and 8 Crohn's Disease [CD]) who were free of corticosteroid treatment and 25 healthy subjects as a control group were enrolled in this study. All patients with IBD were investigated for pulmonary involvement with medical history, physical examination, chest roentgenogram, oxygen saturation, blood eosinophil levels, pulmonary function tests (PFTs), high-resolution computed tomography (HRCT), and FE(NO) level. RESULTS Pulmonary involvement was established in 15 patients (45.5%) with IBD. The FE(NO) level was higher in patients with pulmonary involvement than without pulmonary involvement and healthy controls independent from the pulmonary symptoms, eosinophil count, duration of disease, activity of disease, and surgery history (FE(NO): 32 +/- 20; 24 +/- 8; 14 +/- 8 ppb, respectively) (P < 0.05). In addition, diffusion capacity (DLCO) was found to be significantly lower in patients with CD compared with UC (P < 0.05). CONCLUSIONS This study showed that an increased FE(NO) level may be used for identifying patients with IBD who need further pulmonary evaluation.

Abstract
OBJECTIVES To determine the 3 year mortality of patients admitted to hospital for the treatment of ulcerative colitis (UC). DESIGN Retrospective case note review of all patients admitted to hospital for treatment of active UC over a 6 year period from 1 January 2000. SETTING Teaching hospital with a tertiary referral practice for the management of infiammatory bowel disease. PATIENTS 106 patients (134 admissions) met the inclusion criteria. INTERVENTIONS Elective and emergency colectomy was undertaken in 16 and 26 patients, respectively. MAIN OUTCOME MEASURES Mortality at 3 years. RESULTS There were six deaths after 3 years. Case fatality at 30 days, 1, 2 and 3 years was 1.0% (95% CI 0.2 to 5.1), 1.9% (95% CI 0.2 to 6.6), 2.9% (95% CI 5.9 to 8.0) and 5.7% (95% CI 2.1 to 11.9), respectively. There were no deaths in either surgical group. One patient (89 years, female) died while awaiting emergency colectomy. Patients who died were significantly older at the time of admission (79 years (95% CI 71 to 88 years) vs 41.2 years (95% CI 38 to 45 years)) and were more likely to have comorbid illness (p<0.001). Severity of disease, prior immunosuppressive use, first presentation and smoking status were not associated with increased mortality. CONCLUSIONS Three year mortality following admission for treatment of UC was 5.7% (95% CI 2.1 to 11.9), significantly lower than that reported previously. Mortality was significantly associated with increasing age and the presence of comorbid disease. Disease specific factors such as severity, extent and first presentation were associated with emergency colectomy but not mortality.

Abstract
The description of the prognosis of inflammatory bowel disease (IBD) is based on systematic follow-up of population-based cohorts. A steady increase in incidence of IBD has occurred. The distribution of ulcerative colitis (UC) is fairly uniform with a preponderance of left-sided disease. One-third of Crohn's disease (CD) patients present with colonic disease, one-third with ileocolonic disease and one-third with small bowel disease. IBD is associated with extra-intestinal manifestations (EIMs) in up to 36% of patients. Uveitis and episcleritis are the most common. The cumulative probability of a relapsing course in UC is 90% after 25 years. In CD disease behaviour varies substantially with time. At diagnosis behaviour is inflammatory in 70% of patients. At follow-up there is a change to either stricturing or penetrating disease. Most patients with CD will eventually require surgery. Risk factors for CD recurrence after surgery include penetrating/fistulizing disease behaviour, young age, short duration of disease before first surgery and ileocolonic disease. The incidence of colorectal cancer (CRC) in UC seems to be decreasing. The risk of CRC in CD seems to be equivalent to the risk in UC. Patients with small bowel CD are also at increased risk of small bowel adenocarcinoma. CD is associated with a mortality rate 20-70% higher than expected, whereas mortality in UC is equivalent to that of the general population. The improved prognosis of IBD, especially UC, could be due to a chemopreventive effect of the medications used. Further studies are needed to develop the best strategy for the reduction of mortality and cancer risk in IBD.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for the majority of patients with medically refractory ulcerative colitis (UC) or UC with dysplasia, or familial adenomatous polyposis. Various forms of pouchitis frequently occur after surgery. In fact, pouchitis is the most frequent long-term complication of IPAA in patients with UC, with a cumulative prevalence of up to 50%. The etiology and pathogenesis of pouchitis are not entirely clear. It is generally believed that the initiation and development of the disease process of pouchitis is associated with dysbiosis of pouch reservoir, as evidenced by a favorable response to antibiotic therapy. However, the majority of the patients do not show identifiable etiopathogenetic or triggering factors, therefore being labeled to have idiopathic pouchitis. In contrast, a subgroup of patients, particularly those with antibiotic-refractory pouchitis, may have obvious triggering factors for disease flare-up and progression and may be considered to have secondary pouchitis. Therefore, pouchitis can be classified on the basis of etiology into idiopathic and secondary causes. Approximately 20-30% of patients who present with chronic pouchitis have secondary identifiable and triggering factors, including cytomegalovirus or Clostridium difficile infection, ischemia, concurrent immune-mediated disorders, radiation, collagen deposition, and use of nonsteroidal anti-inflammatory drugs. Careful evaluation of these secondary causes of pouchitis that may contribute to resistance to antibiotics should be performed before the introduction of next-line medical therapy.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical treatment of choice for most patients with ulcerative colitis who require surgery. Although the surgical procedure offers a cure in some patients, postoperative inflammatory and noninflammatory complications are common. Pouchitis is the most common long-term complication of the procedure. Pouchitis represents a spectrum of disease processes with heterogeneous risk factors, clinical phenotypes, natural history, and prognosis. Accurate diagnosis and classification are important for proper treatment and prognosis.

Abstract
AIM To describe the development in incidence, disease localization, activity, surgery and prognosis in two Danish paediatric population-based inflammatory bowel disease (IBD) cohorts comparing the time periods 1962-1987 (period I) and 1998-2006 (period II). MATERIALS AND METHODS Incident IBD patients below 15 years of age were included. Disease localization was classified according to the Montreal classification for ulcerative colitis (UC) patients and into small bowel, large bowel and small and large bowel combined for Crohn's disease (CD) patients. Disease activity and surgery in the first 2 years after diagnosis were assessed. Standardized cancer incidence rates and standardized mortality rates were calculated. RESULTS One hundred and nineteen IBD patients (77 UC and 42 CD) were included. Comparing periods II and I, the incidence rate ratios were 0.81 [95% confidence interval (CI): 0.5-1.4] and 15.6 (95% CI: 7.5-32.7) in UC and CD, respectively. The number of UC patients with extensive disease (E3) increased from period I to II (46.7 vs. 94.1%, P<0.001). No colectomies were performed in UC patients in period II compared with nine in period I (P = 0.13) within the first 2 years after diagnosis. For patients diagnosed in period I, the standardized cancer incidence rate for UC was 37.9 (95% CI: 4.6-136.7) after a median follow-up period of 26 years. CONCLUSION We found a significant 15-fold increase in the incidence of CD and a significant increase in the number of UC patients with extensive disease in period II compared with period I. After a median follow-up time of 26 years, a possible increased risk of colorectal cancer in UC patients was detected.

Abstract
OBJECTIVES Colorectal cancer (CRC) is a feared complication of chronic ulcerative colitis (UC). Annual endoscopic surveillance is recommended for the detection of early neoplasia. 5-Aminosalicylates (5-ASAs) may prevent some UC-associated CRC. Therefore, in patients prescribed 5-ASAs for maintenance of remission, annual surveillance might be overly burdensome and inefficient. We aimed to determine the ideal frequency of surveillance in patients with UC maintained on 5-ASAs. METHODS We performed systematic reviews of the literature, and created a Markov computer model simulating a cohort of 35-year-old men with chronic UC, followed until the age of 90 years. Twenty-two strategies were modeled: natural history (no 5-ASA or surveillance), surveillance without 5-ASA at intervals of 1-10 years, 5-ASA plus surveillance every 1-10 years, and 5-ASA alone. The primary outcome was the ideal interval of surveillance in the setting of 5-ASA maintenance, assuming a third-party payer was willing to pay $100,000 for each quality-adjusted life-year (QALY) gained. RESULTS In the natural history strategy, the CRC incidence was 30%. Without 5-ASA, annual surveillance was the ideal strategy, preventing 89% of CRC and costing $69,100 per QALY gained compared with surveillance every 2 years. 5-ASA alone prevented 49% of CRC. In the setting of 5-ASA, surveillance every 3 years was ideal, preventing 87% of CRC. 5-ASA with surveillance every 2 years cost an additional $147,500 per QALY gained, and 5-ASA with annual surveillance cost nearly $1 million additional per QALY gained compared with every 2 years. In Monte Carlo simulations, surveillance every 2 years or less often was ideal in 95% of simulations. CONCLUSIONS If 5-ASA is efficacious chemoprevention for UC-associated CRC, endoscopic surveillance might be safely performed every 2 years or less often. Such practice could decrease burdens to patients and on endoscopic resources with a minimal decrease in quality-adjusted length of life, because 5-ASA with annual surveillance may cost nearly $1 million per additional QALY gained.

Abstract
OBJECTIVES The incidence of ulcerative colitis (UC) in Asia is increasing but reports on its long-term course are few. We set out determine the incidence, prevalence, and survival rate of UC in the Chinese population and phenotypic stability by longitudinal follow-up. METHODS A cohort of Chinese UC patients were followed up in a tertiary referral center in Hong Kong between 1985 and 2006. Clinical data were prospectively collected since 2001. Population statistics were obtained from the Census and Statistics Department of Hong Kong for the calculation of age-specific incidence, prevalence, and survival. The disease phenotypes at diagnosis and upon follow-up were documented. RESULTS A total of 172 patients (51.7% men) with a median age at diagnosis of 37.0 years (range: 12.0-85.0) were included. The cohort was observed for a total of 1,393 person-years with a median follow-up duration of 7.0 years (range: 0.5-22.0). The age-standardized incidence and prevalence rates of UC per 100,000 were 2.1 (95% confidence interval, CI: 1.1-3.7) and 26.5 (95% CI: 22.6-30.9), respectively, in 2006. The 10-year cumulative rate of proximal extension was 23.8%. Only one patient developed colorectal cancer during the observation period. The cumulative colectomy rates were 2.4% and 7.6% at 1 and 10 years of follow-up. Overall survival was similar to that expected (P=0.07). CONCLUSIONS The incidence of UC has increased sixfold in the past two decades in Hong Kong. The complication, colorectal cancer, and colectomy rates are low in Chinese patients but increase with duration of illness.

Abstract
A rising trend in the incidence and prevalence of inflammatory bowel disease (IBD) in Asia has been recognized for the past two decades. It has been postulated that this phenomenon may be related to the westernization of lifestyles, including changes in dietary habits and environmental changes such as improved sanitation and industrialization. Previously we reported that the incidence and prevalence rates of IBD in Asia were low compared with the West, but there was a notably rising secular trend. In this review, we summarize the recent epidemiological data in Asia, characterize the clinical features, risk factors and genetic susceptibility of Asian IBD patients, and compare these to those of Western IBD patients. In the past decade, the incidence and prevalence of IBD reported across Asia, particularly in East Asia, has continued to increase. Familial clustering is generally uncommon in East Asia but appears to be higher in West Asia. The genetic susceptibilities in Asian IBD patients differ from those of White patients, as NOD2/CARD15 mutations are much less common. The clinical phenotypes and complication rates of Asian IBD resemble the White population in general, but with some differences, including lower surgical rates, higher prevalence of males, and higher prevalence of ileocolonic involvement among East Asian Crohn's disease patients, and a low frequency of primary sclerosing cholangitis among IBD patients in East and Southeast Asia.

Abstract
BACKGROUND & AIMS Data on safety and long-term follow-up evaluation of population-based cohorts of inflammatory bowel disease (IBD) patients treated with infliximab are sparse. The aim of this article is to describe the use of infliximab in a national Danish population-based IBD cohort during 1999-2005. METHODS Medical records of all infliximab-treated IBD patients were scrutinized to abstract information on patient demographics, treatment efficacy, and adverse events. RESULTS A total of 651 patients (619 with Crohn's disease, 15 with ulcerative colitis, and 17 with colonic IBD type unclassified) received infliximab during 1999-2005. A total of 3351 infusions were administered, with a median of 3 infusions per patient. A positive clinical response was observed in 82.7% (95% confidence interval, 79.9-85.5) of patients. Infusion reactions were observed after 146 of 3351 infusions (4.4%). Significantly fewer infusion reactions were seen in patients also receiving azathioprine or methotrexate (63 of 2079; 3.0%), compared with patients not receiving azathioprine or methotrexate (83 of 1272; 6.5%) (P < .0001). Severe adverse events were observed after 112 of 3351 infusions (3.3%) in a total of 95 patients (14.6%). Four patients developed cancer versus 5.9 expected (standardized incidence ratio, 0.7; 95 confidence interval, 0.2-1.7) and 13 patients died versus 6.9 expected (standardized mortality ratio, 1.9; 95% confidence interval, 1.0-3.2). Two deaths caused by infections were possibly related to infliximab. CONCLUSIONS Infliximab seemed effective in IBD and generally was well tolerated. However, rare but severe adverse events occurred, and patients receiving infliximab therefore should be selected carefully and monitored closely. No lymphomas and no increased risk of cancer were observed.
