RESUMO
BACKGROUND & AIMS: In this nationwide study, we explored whether early initiation of biologics is associated with improved outcomes in children and adults with Crohn's disease (CD) and ulcerative colitis (UC). METHODS: All patients diagnosed with CD or UC in Israel (2005-2020) were included in the Epidemiology Group of the Israeli Inflammatory Bowel Disease Research Nucleus cohort, encompassing 98% of the population. We compared disease duration at biologics initiation (ie, 0-3 months, >3-12 months, >1-2 years, and >2-3 years) using the cloning, censoring, and weighting by inverse probabilities method to emulate a target trial, adjusting for time-varying confounders and selection bias. RESULTS: Of the 34,375 included patients (of whom 5240 [15%] were children), 7452 of 19,264 (39%) with CD and 2235 of 15,111 (15%) with UC received biologics. In CD, by 10 years postdiagnosis, the probability of CD-related surgery decreased gradually but modestly with earlier initiation of biologics; a significant difference was noted between >2-3 years (31%) and 0-3 months (18%; P = .02; number needed to treat, 7.7), whereas there was no difference between the 0-3-month and >3-12-month periods. The 10-year probability of steroid dependency for the 0-3-month period (19%) differed both from the >2-3-year (31%; P < .001) and 1-2-year periods (37%; P < .001). In UC, no significant differences in colectomy or steroid dependency rates were observed between the treatment initiation periods. Similar trends were noted in the pediatric population. CONCLUSIONS: Very early initiation of biologics was not associated with some outcomes except for a modest risk reduction of surgery and steroid dependency for CD, which requires confirmation in future studies. In UC, early introduction of biologics was not associated with reduced risk of colectomy or steroid dependency.

BACKGROUND & AIMS: Studies have shown decreased response to coronavirus disease 2019 (COVID-19) vaccinations in some populations. In addition, it is possible that vaccine-triggered immune activation could trigger immune dysregulation and thus exacerbate inflammatory bowel diseases (IBD). In this population-based study we used the epi-Israeli IBD Research Nucleus validated cohort to explore the effectiveness of COVID-19 vaccination in IBD and to assess its effect on disease outcomes. METHODS: We included all IBD patients insured in 2 of the 4 Israeli health maintenance organizations, covering 35% of the population. Patients receiving 2 Pfizer-BioNTech BNT162b2 vaccine doses between December 2020 and June 2021 were individually matched to non-IBD controls. To assess IBD outcomes, we matched vaccinated to unvaccinated IBD patients, and response was analyzed per medical treatment. RESULTS: In total, 12,109 IBD patients received 2 vaccine doses, of whom 4946 were matched to non-IBD controls (mean age, 51 ± 16 years; median follow-up, 22 weeks; interquartile range, 4-24). Fifteen patients in each group (0.3%) developed COVID-19 after vaccination (odds ratio, 1; 95% confidence interval, 0.49-2.05; P = 1.0). Patients on tumor necrosis factor (TNF) inhibitors and/or corticosteroids did not have a higher incidence of infection. To explore IBD outcomes, 707 vaccinated IBD patients were compared with unvaccinated IBD patients by stringent matching (median follow-up, 14 weeks; interquartile range, 2.3-20.4). The risk of exacerbation was 29% in the vaccinated patients compared with 26% in unvaccinated patients (P = .3). CONCLUSIONS: COVID-19 vaccine effectiveness in IBD patients is comparable with that in non-IBD controls and is not influenced by treatment with TNF inhibitors or corticosteroids. The IBD exacerbation rate did not differ between vaccinated and unvaccinated patients.

BACKGROUND & AIMS: Limited population-based data have explored perianal involvement in Crohn's disease (CD) and compared the disease course between severe and non-severe perianal CD (PCD). We aimed to explore the disease course of these phenotypes in a population-based study of CD. METHODS: Cases were identified from the epi-IIRN cohort and included 2 Israeli health maintenance organizations covering 78% of the population. We validated specific algorithms to identify fistulizing PCD and to differentiate severe from non-severe disease by medication utilization, International Classification of Disease, 9th Revision codes, and perianal procedures. RESULTS: A total of 12,904 CD patients were included in an inception cohort from 2005 (2186 pediatric-onset, 17%) providing 86,119 person-years of follow-up. Fistulizing PCD was diagnosed in 1530 patients (12%) (574 with severe PCD, 4%). The prevalence of PCD was 7.9%, 9.4%, 10.3%, and 11.6% at 1, 3, 5, and 10 years from CD diagnosis, respectively. At 5 years, PCD patients were more likely to be hospitalized (36% in non-PCD vs 64% in PCD; P < .001), undergo inflammatory bowel disease-related surgeries (9% vs 38%, respectively; P < .001), and develop anorectal cancer (1.2/10,000 person-years for non-PCD vs 4.2/10,000 for PCD; P = .01). Severe PCD was associated with poorer outcomes compared with non-severe PCD, as shown for hospitalizations (61% in non-severe PCD vs 73% in severe; P = .004) and surgeries (35% vs 43%; P = .001). CONCLUSIONS: Despite higher utilization of immunomodulators and biologics, PCD is associated with poor disease outcomes, especially in severe PCD.

BACKGROUND AND OBJECTIVES: Both perianal and pediatric-onset Crohn disease (CD) disease are associated with complicated disease course and higher drug utilization. we aimed to explore the differences between pediatric and adult-onset perianal CD and their disease course. METHODS: We included all patients with newly diagnosed CD from 2005 to 2019 at two Israeli Health Maintenance Organizations, covering 78% of the population. A combination of ICD-9 codes, radiology and procedures was used to define fistulizing perianal CD (PCD) and its severity according to the association with simple and complex perianal disease. RESULTS: A total of 12,905 patients were included (2186 [17%] pediatric-onset, 10,719 [83%] adults), with a median follow-up of 7.8âyears. PCD was diagnosed in 1530 (12%) patients, with higher incidence in children (308 [14%] children vs 1222 adults [11%]; Pâ <â0.001). Children had higher incidence of severe PCD (141/308 [47%] vs 433/1222 [35%]; Pâ<â0.001). At 5âyears, children with PCD were more likely than adults to be treated with biologics (212 [69%] vs 515 [42%]; odds ratio [OR] 2.6 [95% confidence interval (CI) 1.6-4.0]; Pâ<â0.001) and immunomodulators (238 [74%] vs 643 [53%]; OR 2.8 [95% CI 2.1-3.6]; Pâ<â0.001). PCD in children was still associated with poorer disease outcomes as shown for surgeries (36 [12%] vs 93 [8%]; Pâ=â0.02) and steroid-dependency (52 [17%] vs 156 [13%]; Pâ<â0.001). Multivariable modeling indicated that the severity of PCD is a stronger predictor of disease course than age. CONCLUSION: PCD is more common in pediatric-onset CD and is associated with higher drug utilization and worse disease outcomes, in large due to higher rate of severe PCD in children.

BACKGROUND: Both corticosteroids and exclusive enteral nutrition (EEN) have been used as induction therapy in children with Crohn's disease (CD). AIM: To compare in a nationwide study the long-term outcomes of children with CD receiving either EEN or corticosteroids as induction therapy. METHODS: We retrieved data of all children diagnosed with CD (2005-2020) from the epi-IIRN cohort covering 98% of the Israeli population. The primary outcome was time to complicated disease course (i.e., surgery, steroid-dependency, or at least 2 biologic class). Patients were matched individually utilising propensity score adjustments. RESULTS: We included 410 children treated with EEN and 375 with corticosteroids without other treatments (median follow-up, 4.73 [IQR: 2.2-7.2] years [1433 patient-years]). For 274 matched children, the probability of a complicated course was higher with corticosteroids than EEN at 0.5, 3 and 5 years (14% vs. 4%, 42% vs. 27% and 54% vs. 41%, respectively, p = 0.0066), despite similar use of biologics. Steroid-dependency (10% vs. 2%, 15% vs. 3%, and 20% vs. 5%, respectively, p = 0.00018), and hospitalisations (20% vs. 11%, 37% vs. 26%, and 55% vs. 38%, respectively, p = 0.002) were higher with corticosteroids. During follow-up, children receiving corticosteroids as induction treatment were more often further exposed to corticosteroids, and those on EEN were more often further exposed to nutritional treatment (p < 0.001). Induction with EEN had no advantage over corticosteroids regarding survival probability of surgeries, biologic use and growth. CONCLUSIONS: EEN in paediatric CD is associated with lower long-term risks of corticosteroid dependency and hospitalisation than corticosteroids. These results may lend support to favouring nutritional therapy in paediatric CD.

BACKGROUND: Timely access to quality medical care impacts patient outcomes in inflammatory bowel disease (IBD). In a nationwide study from the epidemiology group of the Israeli IBD research nucleus we aimed to assess the impact of residence and socioeconomic status (SES) on disease outcomes. METHODS: We utilized data from the 4 health maintenance organizations in Israel, representing 98% of the population. Regions were defined as central, northern and southern; SES was graded from lowest to highest (from 1 to 4) as per Israel Central Bureau of Statistics. The primary outcome was steroid dependency, with secondary outcomes of surgeries and biologic therapy use. RESULTS: A total of 28 216 IBD patients were included: 15 818 (56%) Crohn's disease (CD) and 12 398 (44%) ulcerative colitis; 74%, 12% and 14% resided in central, southern, and northern Israel, respectively (SES 1: 21%, SES 4: 12%). Lower SES was associated with steroid dependency (20% in SES 1 vs 12% in SES 4 in CD; P < .001; and 18% vs 12% in ulcerative colitis; P < .001), and higher surgery rates (12% vs 7%; P < .001, and 1.4% vs 0.7%; P = .115, respectively). There were higher steroid dependency and CD surgery rates in peripheral vs central regions. In multivariable models, both SES and peripheral region were independently associated with poorer outcomes. CONCLUSIONS: We found that lower SES and peripheral residence were associated with deleterious outcomes in IBD. This should be considered by policymakers and should encourage strategies for improving outcomes in populations at risk.
In a novel nationwide population study, we found that patients with inflammatory bowel disease living in peripheral regions and those with lower socioeconomic status had significantly worse inflammatory bowel disease outcomes, notably higher corticosteroid dependency, higher surgery rate, and higher repeat surgery rate.

BACKGROUND: Since data on predictors of complicated Crohn's disease (CD) from unselected populations are scarce, we aimed to utilize a large nationwide cohort, the epi-IIRN, to explore predictors of disease course in children and adults with CD. METHODS: Data of patients with CD were retrieved from Israel's 4 health maintenance organizations, whose records cover 98% of the population (2005-2020). Time-to-event modeled a complicated disease course, defined as CD-related surgery, steroid-dependency, or the need for >1 class of biologics. Hierarchical clustering categorized disease severity at diagnosis based on available laboratory results. RESULTS: A total of 16â 659 patients (2999 [18%] pediatric-onset) with 121â 695 person-years of follow-up were included; 3761 (23%) had a complicated course (750 [4.5%] switched to a second biologic class, 1547 [9.3%] steroid-dependency, 1463 [8.8%] CD-related surgery). Complicated disease was more common in pediatric- than adult-onset disease (26% vs 22%, odds ratio, 1.3; 95% confidence interval [CI], 1.2-1.4). In a Cox multivariate model, complicated disease was predicted by induction therapy with biologics (hazard ratio [HR], 2.1; 95% CI, 1.2-3.6) and severity of laboratory tests at diagnosis (HR, 1.7; 95% CI, 1.2-2.2), while high socioeconomic status was protective (HR, 0.94; 95% CI, 0.91-0.96). In children, laboratory tests predicted disease course (HR, 1.8; 95% CI, 1.2-2.5), as well as malnutrition (median BMI Z score -0.41; 95% CI, -1.42 to 0.43 in complicated disease vs -0.24; 95% CI, -1.23 to 0.63] in favorable disease; Pâ <â .001). CONCLUSIONS: In this nationwide cohort, CD course was complicated in one-fourth of patients, predicted by laboratory tests, type of induction therapy, socioeconomic status, in addition to malnutrition in children.
Prognostic factors of complicated disease course are vital for considering early escalation to biologics. In this nationwide cohort, complicated disease course was apparent in approximately one-fourth of patients and was predicted particularly by routinely collected laboratory tests, age, and type of induction therapy at diagnosis.
RESUMO
BACKGROUND: Data on predictors of complicated ulcerative colitis (UC) course from unselected populations cohorts are scarce. We aimed to utilize a nationwide cohort to explore predictors at diagnosis of disease course in children and adults with UC. METHODS: Data of patients diagnosed with UC since 2005 were retrieved from the nationwide epi-IIRN cohort. Complicated disease course was defined as colectomy, steroid-dependency, or the need for biologic drugs. Hierarchical clustering categorized disease severity at diagnosis based on complete blood count, albumin, C-reactive protein and erythrocyte sedimentation rate (ESR), analyzed together. RESULTS: A total of 13â 471 patients with UC (1427 [11%] pediatric-onset) including 103â 212 person-years of follow-up were included. Complicated disease course was recorded in 2829 (21%) patients: 1052 (7.9%) escalated to biologics, 1357 (10%) experienced steroid-dependency, and 420 (3.1%) underwent colectomy. Probabilities of complicated disease course at 1 and 5 years from diagnosis were higher in pediatric-onset (11% and 32%, respectively) than adult-onset disease (4% and 16%; Pâ <â .001). In a Cox multivariate model, complicated course was predicted by induction therapy with steroids (hazard ratio [HR], 1.5; 95% CI, 1.2-2.0), extraintestinal manifestations (HR, 1.3; 95% CI, 1.03-1.5) and the disease severity clusters of blood tests (HR, 1.8; 95% CI, 1.01-3.1), while induction therapy with enemas (HR, 0.6; 95% CI, 0.5-0.7) and older age (HR, 0.99; 95% CI, 0.98-0.99) were associated with noncomplicated course. CONCLUSION: In this nationwide cohort, the probability of complicated disease course during the first 5 years from diagnosis was 32% in pediatric-onset and 16% in adults with UC and was associated with more severe clusters of routinely collected laboratory tests, younger age at diagnosis, extraintestinal manifestations, and type of induction therapy.
Prognostic factors of complicated disease course are vital for clinical decision-making of early escalation to intensive treatment. In this nationwide cohort, one-third of children and one-fifth of adults with UC developed complicated disease course. Disease course was predicted particularly by routinely collected laboratory tests, age, extraintestinal manifestations, and type of induction therapy at diagnosis.
RESUMO
BACKGROUND & AIMS: We conducted this nationwide study to evaluate the association between peripheral blood eosinophilia (PBE) and long-term outcomes in children and adults with inflammatory bowel diseases (IBD). METHODS: Data from the epi-IIRN cohort, a validated population-based IBD database, included patients diagnosed between 2005-2020 who had an eosinophil count at diagnosis, and those of non-IBD controls. PBE was defined as an eosinophil count of >0.5 X109/L Severe disease course was defined as corticosteroid dependency, use of ≥2 biologics from different classes, or surgery. Time-to-outcomes, including severe disease course, was determined by Cox proportional hazard models. RESULTS: Included were 28,133 patients (15,943 Crohn's disease [CD] and 12,190 ulcerative colitis [UC]), and 28,724 non-IBD controls. The prevalence of PBE was 13% in the IBD group and 5% in controls (P < .001). PBE was more prevalent in UC (16.1%) compared to CD (10.6%, OR=1.52 (95%CI 1.42-1.63); P < .001) and in pediatric-onset (23.5%) compared to adult-onset (11%) IBD (OR=2.14 (1.97-2.31); P <.001). In a multivariate analysis, PBE was a predictor of severe disease course in IBD (hazard ratio [HR]=1.49, 95%CI 1.38-1.62, P < .001). PBE also predicted time-to-hospitalization (HR=1.24, 95%CI 1.19-1.30), use of corticosteroids (HR=1.32, 95%CI 1.28-1.36), corticosteroid dependency (HR=1.37, 95%CI 1.31-1.43), and need of biologics (HR=1.27, 95%CI 1.21-1.33). CONCLUSION: In this largest nationwide study, PBE predicted severe IBD course. These findings support the use of PBE as a marker of adverse outcome of IBD and as a potential target for future therapies.
RESUMO
BACKGROUND: Different antibiotic classes were reported to have variable effects on immunogenicity towards anti-tumour necrosis factor [TNF] agents. However, the impact of antibiotic administration on biologic treatment durability was not investigated. We aimed to assess the association between antibiotic treatment and persistence of different classes of biologic therapy in inflammatory bowel disease [IBD] patients. METHODS: Data from the epi-IIRN, a nationwide registry of all Israeli IBD patients were analysed. All patients who filled a prescription of either infliximab, adalimumab, vedolizumab, or ustekinumab, were included. Treatment cessation was defined as drug discontinuation of at least 6 months. Macrolides, cephalosporins, fluoroquinolones, and penicillins with beta-lactamase inhibitors were selected as primary exposure variables. Survival analysis was performed using marginal structural models for each drug separately. RESULTS: In all 13 513 IBD patients, with a total of 39 600 patient-years, were included. Significant differences of overall treatment persistence were demonstrated, with highest persistence rates for ustekinumab and the lowest for infliximab treatment. Macrolides were found to be significantly associated with reduced risk of infliximab cessation (adjusted hazard ratio [aHR] 0.72, 95% CI 0.62-0.89]. Fluoroquinolones and cephalosporins were associated with an elevated risk of adalimumab treatment cessation [aHR 1.33, 95% CI 1.22-1.46; and aHR 1.20, 95% CI 1.08-1.34, respectively]. No significant effects of the studied antibiotics were observed in ustekinumab and vedolizumab users. CONCLUSIONS: Specific antibiotic classes are associated with duration of anti-TNF treatment, but not with durability of vedolizumab or ustekinumab treatments. Further research is required to study the effect of specific antibiotics on response to biologics.
RESUMO
BACKGROUND: The effectiveness of biologics for improving long-term outcomes in patients with Crohn's disease [CD] is still controversial. In this nationwide study, we aimed to evaluate trends of long-term outcomes in all CD patients in Israel during the biologics era. METHODS: Trends of outcomes were analysed using data from the four Israeli health maintenance organisations, covering 98% of the population; joinpoint regression models were used to explore changes of these trends over 2005 to 2019. RESULTS: A total of 16 936 patients were diagnosed with CD in Israel since 2005 (2932 [17%] paediatric onset, 14 004 [83%] adult onset) with 114 947 person-years of follow-up. The cumulative rate of any CD related surgery was 5%, 9%, 11%, and 14% at 1, 3, 5, and 10 years from diagnosis. The increase in use of biologics was sharp (from 8.9% to 36%; average annual percent change [AAPC], 14.3%), and the time to biologics was shorter in recent years (median time of 4.8 [1.9-8.1] years in those diagnosed in 2005-2008 compared with 0.5 [0.2-1.1] years in those diagnosed in 2015-2018; pâ <â 0.001). A significant decrease was noted in the hazard of hospitalisations (1.3 [0.1-4.6] years compared with 0.2 [0.02-0.9] years; pâ <â 0.001), steroid dependency (1.5 [0.2-5.4] years compared with 0.1 [0.02-0.4] years; pâ <â 0.001), and intestinal surgeries [4.7 [1.6-8.2] years compared with 0.6 [0.2-1.4] years; pâ <â 0.001), but not of perianal surgery (4.2 [1.1-7.7] years compared with 0.6 [0.2-1.4] years; pâ =â 0.2). Outcomes were consistently worse in paediatric onset compared with adults. CONCLUSIONS: The rates of hospitalisations, steroid dependency, and intestinal resections decreased in association with increased use of biologics both in children and in adults, but not the rate of perianal surgeries.

BACKGROUND: It is still of debate whether the advent of biologics has been associated with a change in the natural history of ulcerative colitis [UC]. In this nationwide study we evaluated trends of long-term outcomes in all patients diagnosed with UC in Israel during the biologic era. METHODS: Data in the epi-IIRN cohort were retrieved from the four Israeli Health Maintenance Organizations covering 98% of the population, and linked to the Ministry of Health prospective registry on surgeries and hospitalizations. Joinpoint Regression and Kaplan-Meier survival analyses were used, reporting annual average percentage change [AAPC] for each outcome. RESULTS: A total of 13 231 patients were diagnosed with UC since 2005 (1426 [11%] paediatric-onset, 10 310 [78%] adults, 1495 [11%] elderly) with 93 675 person-years of follow-up. The probabilities of surgery after 1, 3 and 5 years from diagnosis were 1.1, 2.3 and 4.1%, respectively, and the corresponding rates of hospitalizations were 22, 33 and 41%. The overall utilization of biologics in UC increased from 0.1% in 2005 to 9.6% in 2019 [AAPC 22.1%] and they were prescribed earlier during the disease course (median of 5.6 years [interquartile range 2.8-9.1] in 2005-2008 vs 0.8 years [0.4-1.5] in 2015-2018; p < 0.001]. Annual rates of surgeries [AAPC -1.3; p = 0.6] and steroid-dependency [AAPC -1.2; p = 0.3] remained unchanged, while rates of hospitalizations slightly decreased [AAPC -1.2; p < 0.001]. Outcomes were consistently worse in paediatric-onset disease than in adults, despite higher utilization of biologics [28% vs 12%, respectively; p < 0.001]. CONCLUSION: During the biologic era rates of surgeries and steroid-dependency have remained unchanged in patients with UC, while rates of hospitalizations have slightly decreased.
