Background Acute gastrointestinal bleeding (AGIB) is common in older patients but the use of iron in this context remains understudied. Aims This study aimed to evaluate prospectively the efficacy of ferric carboxymaltose to treat anaemia in older patients after AGIB. Methods This randomised double-blinded placebo-controlled clinical trial was conducted in 10 French centres. Eligible patients were 65 years or more, had controlled upper or lower gastrointestinal bleeding and a haemoglobin level of 9–11 g/dl. Patients were randomly assigned, in a 1:1 ratio, to receive either one intravenous iron injection of ferric carboxymaltose or one injection of saline solution. The primary endpoint was the difference in haemoglobin level between day 0 and day 42. Secondary endpoints were treatment-emergent adverse events, serious adverse events, rehospitalisation and improvement of quality of life (QOL) at day 180. Results From January 2013 to January 2017, 59 patients were included. The median age of patients was 81.9 [75.8, 87.3] years. At day 42, a significant difference in haemoglobin level increase was observed (2.49 g/dl in the ferric carboxymaltose group vs. 1.56 g/dl in the placebo group, P  = 0.02). At day 180, QOL, measured on European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, improved by 10.5 points in the ferric carboxymaltose group and by 8.2 points in the placebo group (P  = 0.56). Rates of adverse events and rehospitalisation were similar in the two groups. Conclusions Intravenous iron seems safe and effective to treat anaemia in older patients after AGIB and should be considered as a standard-of-care treatment. ClinicalTrials.gov (NCT01690585).

Crohn's disease affects 2.5 million people in Europe (more than 100,000 people in France) and often occurs between the ages of 15 and 30, a period marked by self-construction. However, few studies have focused on the experience of the diagnosis during this sensitive developmental stage. This study aimed to qualitatively explore the experience of Crohn's disease in young adults since their diagnosis. Fifteen young adults (18–35 years) diagnosed with Crohn's disease participated in a semi-directive interview. Narrative data were subjected to a thematic analysis, and thirty percent of the interviews were double-coded. The results revealed an evolution of four main themes since diagnosis: (1) course of care, (2) illness perceptions, (3) disease management and (4) self-perception. For most participants, the onset of the disease was difficult, marked by severe symptoms requiring hospitalization, numerous medical examinations and sometimes several consultations before diagnosis. This journey was more difficult when it was associated with negative relations with the medical staff, who were sometimes perceived as unsupportive. Thus, some people described this diagnostic period as an "ordeal", while others experienced it as a "relief" from their suffering. The announcement of the diagnosis was often a "shock", an "upheaval" or a "downfall", followed by phases of denial associated with a desire to maintain a "normal life" and not to be defined by the disease. Despite a difficult start, most participants grew from their experience with CD, with a sense of a personal development that was made possible by self-regulation processes that enabled them to draw on their own experience and resources to adjust to their illness. By highlighting positive possibilities for evolution, this study suggests the importance of supporting the psychological resources of young adults by proposing, at an early stage, psychological support or therapies focused on acceptance and engagement.

Background: Iron deficiency (ID) is a frequent condition in patients with inflammatory bowel disease (IBD). Aim: Our aim was to investigate the prevalence of ID in patients with IBD. Methods: This was a prospective multicenter cross-sectional study conducted in 21 gastroenterology departments in France between January and March 2020. All adult patients with confirmed IBD who were admitted to the hospital were eligible for inclusion. ID was defined as ferritinemia ≤ 100 μg/L in patients with signs of inflammation (C-reactive protein (CRP) ≥ 5 mg/L) or ferritinemia < 30 μg/L in the absence of inflammation. Results: In total, 1036 IBD (685 Crohn's disease and 351 ulcerative colitis) patients (52.1% women) with a mean age of 41.8 ± 15.5 years were recruited. Approximately half of the patients (504, 51.1%) were in disease remission at the time of enrollment. Systematic monitoring of iron status was performed in 12/21 (57%) participating centers, including measurements of ferritin (12/12, 100%), hemoglobin (11/12, 92%), transferrin saturation (TSAT) (6/12, 50.0%), and serum iron (5/12, 42%). About one-fifth of the patients had been treated with intravenous iron (218, 21.0%), whereas only a small percentage received oral iron (36, 3.5%). ID occurred in 97 patients (23.7% CI 95% 19.8–28.1). Patients with moderate/severe IBD activity (OR: 3.66; CI 95% 24.4–61.2; p = 0.007) or concomitant anemia (OR: 3.66; CI 95% 1.97–6.78; p < 0.001) had an increased likelihood of having ID. Conclusion: Patients with moderate/severe IBD activity or concomitant anemia are at increased risk of ID. Early detection and management of ID in patients with IBD is recommended.

Summary: Background: The burden of inflammatory bowel disease (IBD) is rising worldwide. The goal of IBD treatment is to achieve clinical and endoscopic remission but also prevent disability. Aims: To identify the predictive factors of disability in a large population of patients with IBD. Patients and methods: We conducted a cross‐sectional survey in 42 tertiary centres in France and Belgium. A self‐administered questionnaire was designed to explore patients and their IBD characteristics. IBD‐disk is a validated tool to measure disability in patients with IBD. The IBD‐disk score was then calculated for each patient. Based on a previous study, an overall IBD‐disk score ≥40 was associated with moderate‐to‐severe disability. Results: Among the 2011 patients, 1700 were analysed, including 746 (44%) in self‐reported clinical remission and 752 (44.2%) declaring clinical activity. The patient global assessment of global remission was missing in 200 (11.8%) of 1700 patients. Moderate‐to‐severe disability was significantly increased in patients with BMI >25 kg/m2 (OR = 1.66; 95% CI [1.29‐2.14]), in those having perception of need for a psychotherapist (OR = 2.24; 95% CI [1.79‐3.05]) and social worker (OR = 1.54; 95% CI [1.08‐2.21]). Conversely, male gender (OR = 0.83; 95% CI [0.69‐0.99]), ulcerative colitis (OR = 0.69; 95% CI [0.53‐0.92]), self‐reported clinical remission (OR = 0.59; 95% CI [0.46‐0.77]) and employed or student occupational status (OR = 0.69; 95% CI [0.52‐0.92]) were inversely correlated with disability. Overall, 257 (34.5%) patients who declared being in clinical remission had disability. Conclusion: Determinants of IBD‐related disability include IBD‐related factors but also psychological and social factors. This highlights the importance of a multidisciplinary team in the management of patients with IBD. [ABSTRACT FROM AUTHOR]

Summary: Background: Geographical variations in Crohn's disease (CD) suggest that the environment has a role in the pathogenesis of this condition. Aims: To describe the spatial distribution and the clustering of CD cases in France, and to assess the relationship between the prevalence of CD and environmental risk factors. Methods: We identified all patients with CD included in the French hospital discharge database from 2007 to 2014. Age‐ and gender‐smoothed standardised prevalence ratios over this period were computed for 5610 spatial units. An ecological regression analysis was used to assess the relationship between the risk of CD and ecological variables (health care, latitude, socio‐economic deprivation, urbanisation, proportion of agricultural surfaces and density of industries). Local spatial clusters of high‐CD prevalence were searched for using elliptic spatial scan statistics and characterised in a hierarchical ascendant classification based on the same ecological variables. Results: About 129 089 patients with CD were identified, yielding a crude prevalence of 203 per 100 000 inhabitants. The overall spatial heterogeneity was statistically significant (P <.001). An elevated risk of CD was found to be significantly associated with high‐social deprivation (relative risk [95% confidence interval] = 1.05 [1.02‐1.08]) and high urbanisation (1.09 [1.04‐1.14]). Sixteen significant spatial clusters of high‐CD prevalence were identified; there were no common ecological variables. Conclusions: The geographical distribution of CD prevalence in France is not uniform, and is associated with high levels of social deprivation and urbanisation. Larger ecological databases integrating more detailed environmental and clinical information are needed. [ABSTRACT FROM AUTHOR]

Objective: To date, there are no epidemiological data on microscopic colitis (MC) in France. The aim of this study was to determine the incidence of MC in the Somme department in Northern France, to evaluate clinical characteristics, and to search for risk factors for both collagenous colitis (CC) and lymphocytic colitis (LC).Design: Between January 1, 2005, and December 31, 2007, four pathology units in the Somme department recorded all new cases of MC diagnosed in patients living in the area. Colonic biopsies were reviewed by 4 pathologists together. For each incident case, demographic, clinical, endoscopic, and biological data were collected according to methodology of the EPIMAD registry.Results: One hundred and thirty cases of MC, including 87 CC and 43 LC, were recorded during the three-year study. The mean annual incidence for MC was 7.9/105 inhabitants, 5.3/105 inhabitants for CC, and 2.6/105 inhabitants for LC. Annual standardized incidence of Crohn's disease and ulcerative colitis in the EPIMAD registry during the same period (2005-2007) were 7.4/105 and 4.9/105, respectively. Median age at diagnosis was 63 years for MC, 70 for CC, and 48 for LC. The female-to-male gender ratio was 3.5 for MC, 4.1 for CC, and 2.6 for LC. Median time to diagnosis was 8 weeks. Chronic diarrhea and abdominal pain were, respectively, present in 93 and 47 % of the cases. An autoimmune disease was associated in 28 % of MC cases. At diagnosis, proton pump inhibitor treatment was more often reported in CC than in LC (46 vs 16 %; p = 0.003). Budesonide was effective on diarrhea in 77 % of patients, and thirteen percent of patients became steroid dependent.Conclusion: This population-based study shows that the incidence of MC in France is high and similar to Crohn's disease incidence and confirms that this condition is associated with female gender, autoimmune diseases, and medications.

Geographical variations in Crohn’s Disease incidence have been reported worldwide suggesting putative variations in the distribution of environmental risk factors. A spatial heterogeneity in standardized incidence ratios of Crohn’s Disease was previously detected in northern France. Aims: The goals of this study were to highlight significant atypical clusters in terms of incidence using scan statistics methodology and to study the evolution of these clusters during the study period. Subjects and methods: From 1990 to 2006, the EPIMAD Registry recorded 6,472 Crohn’s Disease cases distributed in 273 administrative areas of northern France. Detection of clusters used space-time scan statistics adjusted for gender and age of patients. Results: Scan statistics provided identification of 18 significant clusters of two types: 14 time-constant clusters and 4 time-varying clusters. Among the fourteen time-constant clusters, 5 clusters of high incidence and 9 clusters of low incidence were detected. Among the four time-varying clusters, 3 clusters of high incidence and 1 cluster of low incidence were identified. Conclusion: The existence of time-constant and time-varying clusters suggests that risk factors of Crohn’s Disease are still at work in our region. [ABSTRACT FROM AUTHOR]

Background: Inflammatory bowel disease [IBD] is associated with an increased risk of developing lymphoma. Although recent data have clarified the epidemiology of lymphoma in IBD patients, the clinical and pathological characteristics of lymphoma in IBD remain poorly known., Methods: Patients with IBD and lymphoma were retrospectively identified in the framework of a national collaborative study including the Groupe d'Étude Thérapeutique des Affections Inflammatoires du Tube Digestif [GETAID] and the Lymphoma Study Association [LYSA]. We characterized clinical and prognostic features for the three most frequent lymphoma subtypes occurring in IBD. We performed a multicentre case-control study. Controls [lymphoma de novo] were matched [5:1] to cases on gender, age at diagnosis, lymphoma subtype, year of diagnosis, and IPI/FLIPI indexes. Overall survival and progression-free survival were compared between cases and controls., Results: In total, 133 IBD patients with lymphoma were included [males = 62.4%, median age at lymphoma diagnosis = 49 years in males; 42 years in females]. Most had Crohn's disease [73.7%] and were exposed to thiopurines [59.4%]. The most frequent lymphoma subtypes were diffuse large B cell lymphoma [DLBCL, 45.1%], Hodgkin lymphoma [HL, 18.8%], and follicular lymphoma [FL, 10.5%]. When matched with 365 controls, prognosis was improved in IBD patients with DLBCL compared to controls [p = 0.0064, hazard ratio = 0.36] or similar [HL and FL]., Conclusions: Lymphomas occurring in IBD patients do not seem to have a worse outcome than in patients without IBD. Due to the rarity of this situation, such patients should be managed in expert centres., (© The Author(s) 2023.

Background and Aim: The inflammatory bowel disease [IBD]-disk is a 10-item self-questionnaire that is used to assess IBD-related disability. The aim of the present study was to evaluate this tool in the assessment of IBD daily-life burden., Methods: A 1-week cross-sectional study was conducted in 42 centres affiliated in France and Belgium. Patients were asked to complete the IBD-disk [best score: 0, worst score: 100] and a visual analogue scale [VAS] of IBD daily-life burden [best score: 0, worst score: 10]. Analyses included internal consistency, correlation analysis, and diagnostic performance assessment., Results: Among the 2011 IBD outpatients who responded to the survey [67.8% of the patients had Crohn's disease], 49.9% were in clinical remission. The IBD-disk completion rate was 73.8%. The final analysis was conducted in this population [n = 1455 patients]. The mean IBD-disk score and IBD daily-life burden VAS were 39.0 ± 23.2 and 5.2 ± 2.9, respectively. The IBD-disk score was well correlated with the IBD daily-life burden VAS [r = 0.67; p <0.001]. At an optimal IBD-disk cut-off of 40, the area under the receiver operating characteristic curve [AUROC] for high IBD daily-life burden [VAS >5] was 0.81 (95% confidence interval [CI]: 0.79-0.83; p <0.001)., Conclusions: In a large cohort of patients, the IBD-disk score was well correlated with IBD daily-life burden, and it could be used in clinical practice., (© The Author(s) 2020.

Background: Patients' experience with healthcare professionals could influence their clinical outcomes., Aims: To assess inflammatory bowel disease (IBD) patients' experience with their disease, their treatment and their relationship with their physician., Methods: A one-week cross-sectional study was conducted in 42 IBD centres. 2011 consecutive outpatients with IBD completed an anonymous self-report questionnaire assessing their experience with and knowledge of IBD., Results: A quantitative assessment of the doctor-patient relationship revealed that patients' knowledge of IBD and IBD treatment ranged from 7.4 to 8.3 out of 10. In addition to IBD physicians, other sources of information about IBD and current treatment mainly included the internet (80% and 63%, respectively) and general practitioners (61% and 54%). Knowledge about education programmes (28%) was poor, resulting in a lack of willingness to further use these resources (25%). Concerns about IBD treatment were raised in 76% of patients, mostly related to the fear of adverse events (47%) and a lack of efficacy (33%). The need of alternative healthcare professionals was reported by 89% of the sample., Conclusion: In a large cohort of patients, we highlighted gaps in the management of patients with IBD regarding the need for higher-quality information and the implementation of alternative healthcare professionals., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

Background: The incidence of inflammatory bowel diseases (IBDs) tended to increase for several decades. Diet is suspected to be a major determinant of the occurrence of these diseases. This prospective study aimed to assess the associations among occurrence of IBD, dietary patterns, and ultra-processed food in the French NutriNet-Santé cohort., Methods: Participants of the NutriNet-Santé cohort who completed at least three 24-hour dietary records were included. Incident IBD cases were identified from 3 questionnaires and confirmed by phone or email interview. Major dietary patterns (DPs) were computed using a principal component analysis (PCA) based on 29 food groups' consumption, whereas proportions of ultra-processed foods (UPFs) were obtained using the NOVA classification. Multivariable Poisson models were performed to evaluate associations among DP quintiles, UPF proportion (UPFp) in the diet, and incident IBD., Results: A total of 105,832 participants were included, contributing 238,924 person-years in a mean follow-up of 2.3 ± 2.2 years. Among them, 75 participants reported an incident IBD. Three major DPs were retained: "healthy," "traditional," and "western." No significant association was found for DPs and UPFp after adjustments for covariates., Conclusions: In this study, neither DPs nor UPF proportion in the diet were significantly associated with the risk of incident IBD after adjustments for covariates. Further studies are needed to investigate the long-term association between diet and IBD., (© 2020 Crohn’s & Colitis Foundation. Published by Oxford University Press. All rights reserved.

Introduction: This study aimed to assess the association between incident Crohn's disease (CD) or incident ulcerative colitis (UC) and dietary zinc intake., Methods: NutriNet-Santé cohort's participants who completed at least three 24-hour dietary records were included and incident CD or UC cases were identified. Multivariable Poisson models were performed to assess associations between tertiles of zinc intake and CD or UC., Results: Among the 105,832 participants, 27 reported incident CD and 48 reported incident UC. The relative risks of CD decreased with dietary zinc intakes. Compared with participants with the lowest tertile of zinc intake, the relative risks for CD were 0.60 (95% confidence interval [0.22-1.66]) and 0.12 (95% confidence interval [0.02-0.73]) for the second and the highest tertiles, respectively (Ptrend = 0.02). No significant association was observed for UC., Discussion: Dietary zinc intake was inversely associated with incident CD.

Introduction: Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD., Method: All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD., Results: A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up., Conclusion: During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients., (Copyright © 2019 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press.

Background: Pediatric-onset Crohn's disease (CD) may represent a more severe form of disease. The aim of this study was to describe long-term outcome and identify associated risk factors of complicated behavior in a large population-based pediatric-onset CD cohort., Patients and Methods: Cases included all patients recorded in the EPIMAD registry diagnosed with definite or probable CD between January 1988 and December 2004, under the age of 17 years at the time of diagnosis, with at least two years of follow-up., Results: Five hundred and thirty-five patients were included. Median follow-up was 11.1 years [IQR, 7.3-15.0]. At the end of follow-up, 8% (n = 44) of patients had pure ileal disease (L1), 8% (n = 44) had pure colonic disease (L2), and 83% (n = 439) had ileocolonic disease (L3). L4 disease and perianal disease were observed in 42% (n = 227) and 16% (n = 85) of patients, respectively. At the end of follow-up, 58% (n = 308) of patients presented complicated disease behavior (B2, 39% and B3, 19%), and 42% (n = 163) of patients with inflammatory behavior at diagnosis had evolved to complicated behavior. During follow-up, 86% of patients (n = 466) received at least one course of corticosteroids, 67% (n = 357) of patients had been exposed to immunosuppressants and 35% (n = 187) of patients received at least one anti-TNF agent. Forty-three percent (n = 230) of patients underwent at least one intestinal resection. The overall mortality rate was 0.93% and the SMR was 1.6 [0.5-3.8] (p = 0.20). Five cancers were reported with a crude cancer incidence rate of 1.1% and an SIR of 3.3 [1.2-7.0] (p = 0.01). In a multivariate Cox model, ileal (HR, 1.87 [1.09-3.21], p = 0.022) or ileocolonic (HR, 1.54 [1.01-2.34], p = 0.042) and perianal lesions at diagnosis (HR, 1.81 [1.13- 2.89], p = 0.013) were significantly associated with complicated behavior., Conclusion: About 80% of patients with pediatric-onset CD presented extensive ileocolonic disease during follow-up. The majority of patients evolved to complicated behavior. Surgery, cancer and mortality were observed in 43%, 0.9% and 0.9% of patients, respectively., (Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Background: Extraintestinal manifestations (EIM) have been associated with more severe course of inflammatory bowel disease. The aim was to study the frequency of EIM in pediatric- and elderly-onset Crohn's disease (CD) and the factors associated with EIM and their impact on long-term disease outcome., Methods: Pediatric- (age at diagnosis younger than 17 years) and elderly-onset CD patients (age at diagnosis 60 years or older) from a prospective population-based registry (EPIMAD) were recruited. Data on EIM and clinical factors at diagnosis and at maximal follow-up were collected., Results: We included 535 pediatric- and 370 elderly-onset patients (median age 14.5 and 69.9 years; median follow-up 11.1 and 5.9 years). Extraintestinal manifestations presented in 23.5% of childhood-onset and 4.9% of elderly-onset individuals at diagnosis, while in 29.8% and 5.9% of patients, EIM developed newly during the follow-up (hazard ration [HR] 4.4, 95% CI, 2.7-7.0, P < 0.001). The most frequently involved organ in both age cohorts, either at diagnosis or during disease course, were joints (pediatric: 11.2% and 22.6%; elderly: 3.2% and 3.5%, respectively) followed by skin (pediatric: 15.9% and 13.6%; elderly: 2.7% and 2.7%, respectively). Extraintestinal manifestations at diagnosis were associated with increased risk for corticosteroids (HR 1.42, 95% CI, 1.14-1.78 and HR 3.38, 95% CI, 1.88-6.08) and immunosuppressive therapy (HR 1.30, 95% CI, 1.02-1.65 and HR 4.24, 95% CI, 1.91-9.42), in both age populations., Conclusions: Extraintestinal manifestations occurred at lower frequency in elderly-onset compared with pediatric-onset patients. In both age populations, presence of EIM at diagnosis independently increased the need for corticosteroid and immunosuppressive treatment.

Background and Aims: Changes in body composition have been described in patients with Crohn's disease, but their predictive performances on disease evolution remain undefined. The aims of our study were to assess, in patients with Crohn's disease requiring abdominal computed tomography, body composition by computed tomography, and to study the outcome according to various body composition parameters at the time of the computed tomography., Methods: Patients with Crohn's disease who underwent abdominal computed tomography for suspected complications were retrospectively included. The definition of adverse outcome included death or need for surgery within 6 months of the computed tomography. Skeletal muscle index and visceral and subcutaneous adiposity indexes were calculated from tissue surface areas measured at the third lumbar vertebra, divided by the height squared., Results: The prevalence of underweight was 26.8% and the prevalence of sarcopenia was 33.6%. After gender adjustment, skeletal muscle index tended to be reduced in patients with adverse outcome, compared with patients without surgery or death [p = 0.07]. Moreover, subcutaneous adiposity index and visceral adiposity index were significantly lower in patients with surgery or death [p = 0.009 and p < 0.001, respectively]. These differences were almost equivalent in both genders for the subcutaneous adiposity index but were clearly stronger in men for the visceral adiposity index., Conclusions: Subcutaneous and visceral adiposity indexes correlate inversely with adverse outcome in patients with Crohn's disease. Alteration of body composition assessed by computed tomography in these patients appears to be a marker of disease severity.

Background: Recent population-based study of elderly-onset Crohn's disease patients reported age-related differences in disease phenotype and outcome., Aims: The aim was to assess the impact of age at diagnosis on natural history of elderly-onset ulcerative colitis patients with emphasis on disease presentation, phenotype and treatment., Methods: Elderly-onset patients with ulcerative colitis (≥60 years at diagnosis) registered in a French population-based Registry EPIMAD (1988-2006) were included. Demographic and clinical data at diagnosis and at maximal follow-up were collected using predefined questionnaire., Results: Four-hundred and sixty-five elderly-onset ulcerative colitis patients were included (median follow-up 6.2 years); 276 (59%) were <70 and 189 (41%) ≥70 years at diagnosis. Patients aged <70 years presented with more rectal bleeding (86% vs. 79%, p = .06) and abdominal pain (44% vs. 34%, p = .04) while those ≥70 years had higher rate of left-sided colitis (62% vs. 49%; p = .02). Cumulative exposure to 5-ASA, corticosteroids and immunosuppressants was similar between the groups as well as surgery rate. However, patients <70 years were significantly more steroid-resistant than older individuals (12% vs. 3%, p < .05) while no significant difference in steroid-dependency was observed., Conclusion: Patients with elderly-onset ulcerative colitis differed in presentation, disease phenotype and response to medication with respect to age at diagnosis., (Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l.

Objectives: Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period., Methods: Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification., Results: 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/10 5 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/10 5 (+126%; P<0.001) and for UC, from 1.6 to 4.1/10 5 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC., Conclusions: In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Background & Aims: Little is known about long-term outcomes of patients with Crohn's disease (CD) after infliximab withdrawal. We aimed to describe the long-term outcomes of patients with CD in clinical remission after infliximab treatment was withdrawn., Methods: We performed a retrospective analysis of data from the 115 patients included in the infliximab discontinuation in patients with CD in stable remission on combined therapy with antimetabolites (STORI) study, performed at 20 centers in France and Belgium from March 2006 through December 2009. The STORI cohort was a prospective analysis of risk and factors associated with relapse following withdrawal of maintenance therapy with infliximab, maintained on antimetabolites, while in clinical remission. We collected data from the end of the study until the last available follow-up examination on patient surgeries, new complex perianal lesions (indicating major complications), and need for and outcomes of restarting therapy with infliximab or another biologic agent. The de-escalation strategy was considered to have failed when a major complication or infliximab restart failure occurred., Results: Of the 115 patients initially included, data from 102 patients (from 19 of the 20 study centers) were included in the final analysis. The median follow-up time was 7 years. Twenty-one percent of the patients did not restart treatment with infliximab or another biologic agent and did not have a major complication 7 years after infliximab withdrawal (95% CI, 13.1-30.3). Among patients who restarted infliximab, treatment failed for 30.1% 6 years after restarting (95% CI, 18.5-42.5). Overall, at 7 years after stopping infliximab therapy, major complications occurred in 18.5% of patients (95% CI, 10.2-26.8) whereas 70.2% of patients had no failure of the de-escalation strategy (95% CI, 60.2-80.1). Factors independently associated with major complications were upper-gastrointestinal location of disease, white blood cell count ≥ 5.0 × 10 9 /L, and hemoglobin level ≤12.5 g/dL at the time of infliximab withdrawal. Patients with at least 2 of these factors had a more than 40% risk of major complication in the 7 years following infliximab withdrawal., Conclusions: In a long-term follow-up of the STORI cohort (7 years) one fifth of the patients did not restart infliximab or another biologic agent and did not develop major complications. Seventy percent of patients had no failure of the de-escalation strategy (no major complication and no failure of infliximab restart)., (Copyright © 2018 AGA Institute. Published by Elsevier Inc.

Objectives: Cancer may be a complication of inflammatory bowel disease (IBD) or its treatment. In elderly onset IBD patients the risk of malignancy is of particular concern. We studied this risk in a population-based cohort of elderly onset IBD patients., Methods: In a French population-based cohort, we identified 844 patients aged >60 years at IBD diagnosis from 1988 to 2006, including 370 Crohn's disease (CD) and 474 ulcerative colitis (UC). We compared incidence of cancer among IBD patients with that observed in the French Network of population-based Cancer Registries (FRANCIM). Confidence interval (CI) was estimated assuming a Poisson-specific law for rare events. Results were expressed using the standardized incidence ratios (SIRs) and their CI 95%., Results: Median age at IBD diagnosis was 70 (65-76) years in CD and 69 (64-74) in UC. Median follow-up was 6 (2-11) years for both diseases with a number of person-years of 5,598. Among the 844 elderly onset IBD cases, 98 (11.6%; 42 CD and 56 UC) developed a cancer after IBD diagnosis (67 men and 31 women) corresponding to an overall SIR of 0.97 (0.80-1.18). These cancers occurred at a median age of 77 years (71-80) and 75 years (71-81) in patients with CD and UC, respectively. Median time between IBD diagnosis and cancers was 78 months (40-121). There was no significant increased risk of colorectal cancer in IBD (SIR=1.03 (0.62-1.70), CD (SIR=1.20 (0.57-2.52) nor in UC (SIR=0.91 (0.45-1.82) without significant protective role of 5-aminosalicylic acid (hazard ratio (HR)=0.7 (0.2-2.6)). No significant risk for other intestinal cancers was found, especially for small bowel carcinoma. An increased risk of malignant lymphoproliferative disorders was found in all IBD and in CD: SIR=2.49 (1.25-4.99) and SIR=3.09 (1.16-8.23), respectively. An increased risk of myeloproliferative disorders was found in all IBD (SIR=2.18 (1.09-4.35)). Thiopurines exposure, using a time-dependant Cox model, was not found as associated with an increased risk to develop cancer, HR=0.90 (0.48-1.68)., Conclusions: There is no increased risk for developing intestinal cancer among patients with elderly onset IBD in this population-based cohort. There are increased risks of developing lymphoproliferative and myeloproliferative disorders in all IBD. Thiopurines exposure was not found as associated with an increased risk to lymphoproliferative disorders. These data reinforce the difference between elderly onset IBD as compared with patients with younger age at IBD onset.

Background & Aims: Colonic strictures complicate inflammatory bowel disease (IBD) and often lead to surgical resection to prevent dysplasia or cancer. We assessed the frequency of dysplasia and cancer among IBD patients undergoing resection of a colorectal stricture., Methods: We analyzed data from the Groupe d'études et thérapeutiques des affections inflammatoires du tube digestif study. This was a nationwide retrospective study of 12,013 patients with IBD in France who underwent surgery for strictures at 16 centers from August 1992 through January 2014 (293 patients for a colonic stricture, 248 patients with Crohn's disease, 51% male, median age at stricture diagnosis of 38 years). Participants had no preoperative evidence of dysplasia or cancer. We collected clinical, endoscopic, surgical, and pathology data and information on outcomes., Results: When patients were diagnosed with strictures, they had IBD for a median time of 8 years (3-14). The strictures were a median length of 6 cm (4-10) and caused symptoms in 70% of patients. Of patients with Crohn's disease, 3 (1%) were found to have low-grade dysplasia, 1 (0.4%) was found to have high-grade dysplasia, and 2 (0.8%) were found to have cancer. Of patients with ulcerative colitis, 1 (2%) had low-grade dysplasia, 1 (2%) had high-grade dysplasia, and 2 (5%) had cancer. All patients with dysplasia or cancer received curative surgery, except 1 who died of colorectal cancer during the follow-up period. No active disease at time of surgery was the only factor associated with dysplasia or cancer at the stricture site (odds ratio, 4.86; 95% confidence interval, 1.11-21.27; P = .036)., Conclusions: In a retrospective study of patients with IBD undergoing surgery for colonic strictures, 3.5% were found to have dysplasia or cancer. These findings can be used to guide management of patients with IBD and colonic strictures., (Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Unlabelled: Data on the natural history of elderly-onset inflammatory bowel disease (IBD) are scarce., Methods: In a French population-based cohort we identified 841 IBD patients >60 years of age at diagnosis from 1988 to 2006, including 367 Crohn's disease (CD) and 472 ulcerative colitis (UC)., Results: Median age at diagnosis was similar for CD (70 years (IQR: 65-76)) and UC (69 years (64-74)). Median follow-up was 6 years (2-11) for both diseases. At diagnosis, in CD, pure colonic disease (65%) and inflammatory behaviour (78%) were the most frequent phenotype. At maximal follow-up digestive extension and complicated behaviour occurred in 8% and 9%, respectively. In UC, 29% of patients had proctitis, 45% left-sided and 26% extensive colitis without extension during follow-up in 84%. In CD cumulative probabilities of receiving corticosteroids (CSs), immunosuppressants (ISs) and anti tumor necrosis factor therapy were respectively 47%, 27% and 9% at 10 years. In UC cumulative probabilities of receiving CS and IS were 40% and 15%, respectively at 10 years. Cumulative probabilities of surgery at 1 year and 10 years were 18% and 32%, respectively in CD and 4% and 8%, respectively in UC. In CD complicated behaviour at diagnosis (HR: 2.6; 95% CI 1.5 to 4.6) was associated with an increased risk for surgery while CS was associated with a decreased risk (HR: 0.5; 0.3 to 0.8). In UC CS was associated with an increased risk (HR: 2.2; 1.1 to 4.6) for colectomy., Conclusions: Clinical course is mild in elderly-onset IBD patients. This information would need to be taken into account by physicians when therapeutic strategies are established.

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.

Most data regarding the natural history of inflammatory bowel diseases and their therapeutic management are from tertiary referral-centres. However, the patients followed in these centres represent a selected sample and extrapolation of these data to the general population is disputable. The EPIMAD Registry covers a large area of Northern France with almost 6 million inhabitants representing 9.3% of the entire French population. From 1988 to 2008, 18,170 incident patients were recorded in the registry including 8071 incident Crohn's disease, 5113 incident ulcerative colitis and 591 unclassified inflammatory bowel disease cases. The aim of this study was to review some of the most recent information obtained from this large population-based registry since its launch in 1988., (Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.

Background: To describe long-term postoperative evolution of pediatric-onset Crohn's disease (CD) and identify predictors of outcome we studied a population-based cohort (1988-2004) of 404 patients (0-17 years), of which 130 underwent surgery., Methods: Risks for a second resection and first need for immunosuppressors (IS) and/or biologics were estimated by survival analysis and Cox models used to determine predictors of outcome. Impact of time of first surgery on nutritional catch-up was studied using regression., Results: In all, 130 patients (70 females) with a median age at diagnosis of 14.2 years (interquartile range: 12-16) were followed for 13 years (9.4-16.6). Probability of a second resection was 8%, 17%, and 29% at 2, 5, and 10 years, respectively. In multivariate analysis, age <14, stenosing (B2) and penetrating (B3) behaviors and upper gastrointestinal location (L4) at diagnosis were associated with an increased risk of second resection. Probability of receiving IS or biologics was 18%, 34%, and 47% at 2, 5, and 10 years, respectively. In multivariate analysis, L4 was a risk factor for requiring IS or biologics, while surgery within 3 years after CD diagnosis was protective. Catch-up in height and weight was better in patients who underwent surgery within 3 years after CD diagnosis than those operated on later., Conclusions: In this pediatric-onset CD study, mostly performed in a prebiologic era, a first surgery performed within 3 years after CD diagnosis was associated with a reduced need for IS and biologics and a better catch-up in height and weight compared to later surgery.

Background & Aims: It is important to determine whether infliximab therapy can be safely interrupted in patients with Crohn's disease who have undergone a period of prolonged remission. We assessed the risk of relapse after infliximab therapy was discontinued in patients on combined maintenance therapy with antimetabolites and identified factors associated with relapse., Methods: We performed a prospective study of 115 patients with Crohn's disease who were treated for at least 1 year with scheduled infliximab and an antimetabolite and had been in corticosteroid-free remission for at least 6 months. Infliximab was stopped, and patients were followed up for at least 1 year. We associated demographic, clinical, and biologic factors with time to relapse using a Cox model., Results: After a median follow-up period of 28 months, 52 of the 115 patients experienced a relapse; the 1-year relapse rate was 43.9% ± 5.0%. Based on multivariable analysis, risk factors for relapse included male sex, the absence of surgical resection, leukocyte counts >6.0 × 10(9)/L, and levels of hemoglobin ≤145 g/L, C-reactive protein ≥5.0 mg/L, and fecal calprotectin ≥300 μg/g. Patients with no more than 2 of these risk factors (approximately 29% of the study population) had a 15% risk of relapse within 1 year. Re-treatment with infliximab was effective and well tolerated in 88% of patients who experienced a relapse., Conclusions: Approximately 50% of patients with Crohn's disease who were treated for at least 1 year with infliximab and an antimetabolite agent experienced a relapse within 1 year after discontinuation of infliximab. However, patients with a low risk of relapse can be identified using a combination of clinical and biologic markers., (Copyright © 2012 AGA Institute. Published by Elsevier Inc.

Background: We examined short- and long-term benefits and safety of infliximab (IFX) in a population-based cohort of Crohn's disease (CD) patients <17 years old at diagnosis., Methods: The following parameters were assessed: short- and long-term efficacy of IFX, impact of drug efficacy, and mode of administration on rate of resection surgery, growth and nutritional catch-up, and adverse events (AEs)., Results: In all, 120 patients (69 female) required IFX with a median duration of 32 months (Q1 = 8-Q3 = 60). Median age at diagnosis was 14.5 years (12-16) and median interval between diagnosis and IFX initiation was 41 months (22-78). Median follow-up since CD diagnosis was 111 months (75-161). Fifty patients (42%) received episodic and 70 (58%) maintenance therapy. Sixty-five (54%) patients were in the "IFX efficacy" group: 38 (32%) still receiving IFX at the last visit and 27 (22%) stopping IFX while in remission. The "IFX failure" group included 55 (46%) patients: 17 (14%) who stopped IFX due to AEs and 38 (32%) nonresponders. The risk of surgery was reduced (P = 0.009) in the "IFX efficacy" group and lower (P = 0.03) in patients with scheduled versus episodic therapy. Patients in the "IFX efficacy" group had significant catch-up growth (P = 0.04), while those in the "IFX failure" group did not. Twenty-four patients presented AEs leading to cessation of IFX in 17 of them., Conclusions: In this population-based cohort of pediatric-onset CD, IFX treatment was effective in more than half of patients during a median follow-up of 32 months. Long-term IFX responders had a lower rate of surgery and improved catch-up in growth, especially when receiving scheduled IFX therapy., (Copyright © 2011 Crohn's & Colitis Foundation of America, Inc.)

Objectives: Growth retardation and malnutrition are major features of pediatric Crohn's disease (CD). We examined nutritional and growth parameters from diagnosis to maximal follow-up in a population-based pediatric cohort, and we determined predictive factors., Methods: A total of 261 patients (156 boys, 105 girls) with onset of CD before the age of 17 were identified from 1988 to 2004 through the EPIMAD registry (Registre des Maladies Inflammatoires Chroniques de l'Intestin) in northern France. Median age at diagnosis was 13 years (11.2-15.4) and median follow-up was 73 months (46-114). Z-scores of height/age, weight/age, and body mass index (BMI)/age were determined. Multivariate stepwise regression analysis identified predictive factors for malnutrition and growth retardation at maximal follow-up., Results: At diagnosis, 25 children (9.5%) showed height less than -2 s.d., 70 (27%) weight less than -2 s.d., and 84 (32%) BMI less than -2 s.d. At maximal follow-up, growth retardation was present in 18 children (6.9%), whereas 40 (15%) had malnutrition. Nutritional status was more severely impaired in children with stricturing disease. Growth and nutritional retardation at diagnosis, young age, male gender, and extraintestinal manifestations at diagnosis were indicators of poor prognosis. A significant compensation was observed for weight and BMI in both genders and for height in girls. No treatment was associated with height, weight, or BMI at maximal follow-up., Conclusions: In our pediatric population-based study, growth retardation and severe malnutrition were still present at maximal follow-up in 6.9 and 15% of CD children, respectively. Young boys with substantial inflammatory manifestations of CD have a higher risk of subsequent growth failure, especially when growth retardation is present at diagnosis.
