Jayasooriya N, Saxena S, Blackwell J, Bottle A, Creese H, Petersen I, Pollok RCG. Associations between prior healthcare use, time to diagnosis, and clinical outcomes in inflammatory bowel disease: a nationally representative population-based cohort study. BMJ Open Gastroenterol 2024; 11:e001371. [PMID: 38802264 PMCID: PMC11131120 DOI: 10.1136/bmjgast-2024-001371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 04/23/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Timely diagnosis and treatment of inflammatory bowel disease (IBD) may improve clinical outcomes. OBJECTIVE Examine associations between time to diagnosis, patterns of prior healthcare use, and clinical outcomes in IBD. DESIGN Using the Clinical Practice Research Datalink we identified incident cases of Crohn's disease (CD) and ulcerative colitis (UC), diagnosed between January 2003 and May 2016, with a first primary care gastrointestinal consultation during the 3-year period prior to IBD diagnosis. We used multivariable Cox regression to examine the association of primary care consultation frequency (n=1, 2, >2), annual consultation intensity, hospitalisations for gastrointestinal symptoms, and time to diagnosis with a range of key clinical outcomes following diagnosis. RESULTS We identified 2645 incident IBD cases (CD: 782; UC: 1863). For CD, >2 consultations were associated with intestinal surgery (adjusted HR (aHR)=2.22, 95% CI 1.45 to 3.39) and subsequent CD-related hospitalisation (aHR=1.80, 95% CI 1.29 to 2.50). For UC, >2 consultations were associated with corticosteroid dependency (aHR=1.76, 95% CI 1.28 to 2.41), immunomodulator use (aHR=1.68, 95% CI 1.24 to 2.26), UC-related hospitalisation (aHR=1.43, 95% CI 1.05 to 1.95) and colectomy (aHR=2.01, 95% CI 1.22 to 3.27). For CD, hospitalisation prior to diagnosis was associated with CD-related hospitalisation (aHR=1.30, 95% CI 1.01 to 1.68) and intestinal surgery (aHR=1.71, 95% CI 1.13 to 2.58); for UC, it was associated with immunomodulator use (aHR=1.42, 95% CI 1.11 to 1.81), UC-related hospitalisation (aHR=1.36, 95% CI 1.06 to 1.95) and colectomy (aHR=1.54, 95% CI 1.01 to 2.34). For CD, consultation intensity in the year before diagnosis was associated with CD-related hospitalisation (aHR=1.19, 95% CI 1.12 to 1.28) and intestinal surgery (aHR=1.13, 95% CI 1.03 to 1.23); for UC, it was associated with corticosteroid use (aHR=1.08, 95% CI 1.04 to 1.13), corticosteroid dependency (aHR=1.05, 95% CI 1.00 to 1.11), and UC-related hospitalisation (aHR=1.12, 95% CI 1.03 to 1.21). For CD, time to diagnosis was associated with risk of CD-related hospitalisation (aHR=1.03, 95% CI 1.01 to 1.68); for UC, it was associated with reduced risk of UC-related hospitalisation (aHR=0.83, 95% CI 0.70 to 0.98) and colectomy (aHR=0.59, 95% CI 0.43 to 0.80). CONCLUSION Electronic records contain valuable information about patterns of healthcare use that can be used to expedite timely diagnosis and identify aggressive forms of IBD.

Pediatric Crohn's Disease in the Upper Gastrointestinal Tract: Clinical, Laboratory, Endoscopic, and Histopathological Analysis. Diagnostics (Basel) 2024; 14:877. [PMID: 38732292 PMCID: PMC11083814 DOI: 10.3390/diagnostics14090877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/18/2024] [Accepted: 04/21/2024] [Indexed: 05/13/2024] Open
Abstract
Crohn's disease (CD) is a progressive, multifactorial, immune-mediated disease characterized by chronic inflammation of any part of the gastrointestinal (GI) tract. Pediatric patients present with a more extensive form of the disease, especially in the upper GI tract with various histopathological inflammatory patterns. Our study aims to analyze the clinical, laboratory, endoscopic, and histopathological findings in children with diagnosed CD and compare results on the initial and follow-up tests. We have included 100 children and adolescents with CD, with performed endoscopic and histopathological (HP) procedures. The results of multiple biopsies executed in these 8 years were matched and compared. We found a statistically significant frequency reduction in stool changes (65.52% to 18.18%), weight loss (35.24% to 4%), and abdominal pain (41.86% to 6.67%) as presenting symptoms. There was an improvement in all laboratory values: fecal calprotectin (1000 to 60,8 μg/g), C-reactive protein (12.2 to 1.9 mg/L), and albumin (36 to 41 g/L). On esophagogastroduodenoscopy and ileo-colonoscopy 36.59% and 64.86% patients had specific findings, respectively. A total of 32 patients had evidence of Crohn's disease in the upper GI tract. Non-caseating granulomas were found on 9% of oesophageal, 18% of gastric, and 12% of duodenal biopsies. In the lower GI tract, we have observed a disease progression in the rectum (72.29 to 82.22%) and descending colon (73.49 to 80%). There was no registered disease progression in the upper GI tract. Our study demonstrated a significant decline in the frequency of symptoms and an improvement in laboratory values on the follow-up examinations. More than a third of our patients had specific endoscopic and HP findings in the upper GI tract, and an additional 23% had HP findings highly suggestive of CD. We demonstrated the importance of regular clinical, laboratory, endoscopic, and histopathological assessments of pediatric CD patients.

Abstract
Background Understanding the molecular pathogenesis of inflammatory bowel disease (IBD) has led to the discovery of new therapeutic targets that are more specific and effective. Our aim was to explore the molecular pathways and genes involved in IBD pathogenesis and to identify new therapeutic targets and novel biomarkers that can aid in the diagnosis of the disease. Methods To obtain the largest possible number of samples and analyze them comprehensively, we used a mega-analysis approach. This involved reprocessing raw data from multiple studies and analyzing them using bioinformatic and machine learning techniques. Results We analyzed a total of 697 intestinal biopsies of Ulcerative Colitis (n = 386), Crohn's disease (n = 183) and non-IBD controls (n = 128). A machine learning analysis detected 34 genes whose collective expression effectively distinguishes inflamed biopsies of IBD patients from non-IBD control samples. Most of these genes were upregulated in IBD. Notably, among these genes, three novel lncRNAs have emerged as potential contributors to IBD development: ENSG00000285744, ENSG00000287626, and MIR4435-2HG. Furthermore, by examining the expression of 29 genes, among the 34, in blood samples from IBD patients, we detected a significant upregulation of 12 genes (p-value < 0.01), underscoring their potential utility as non-invasive diagnostic biomarkers. Finally, by utilizing the CMap library, we discovered potential compounds that should be explored in future studies for their therapeutic efficacy in IBD treatment. Conclusion Our findings contribute to the understanding of IBD pathogenesis, suggest novel biomarkers for IBD diagnosis and offer new prospects for therapeutic intervention.

Abstract
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.

Early Use of Biologics Reduces Healthcare Costs in Crohn's Disease: Results from a United States Population-Based Cohort. Dig Dis Sci 2024; 69:45-55.

Abstract
BACKGROUND Early initiation of biologics in moderate-to-severe Crohn's disease (CD) may significantly alter disease progression, resulting in better patient outcomes. Limited real-world data exist on the impact of early biologic use in patients with CD in the United States. AIMS We aimed to characterize biologic initiation and subsequent healthcare resource utilization (HCRU) in adults with recently diagnosed CD. METHODS Patients with CD who initiated biologic treatment within 2 years of diagnosis (index date) were identified from medical and pharmacy claims (Merative L.P. MarketScan Database from 2010 to 2016) and classified as early (≤ 12 months post-index) or late (> 12-24 months post-index) biologic initiators. Propensity score matching balanced patient characteristics up to 1 year post-index. Differences in HCRU frequency and costs 1-2 years post-index were compared between the matched groups. RESULTS After propensity score matching, 672 pairs of early and late biologic initiators were identified. Patients who initiated biologics early had fewer outpatient visits (15.5 vs 19.8, 95% confidence interval [CI] for difference: 2.7, 6.1) and lower total medical costs ($13,646.20 vs $22,180.70, 95% CI for difference: 4748.9, 12,320.1) 1-2 years post-index than late biologic initiators. Early biologic initiators had higher medication costs 1-2 years post-index ($33,766.30 vs $30,580.70, 95% CI: 546.1, 5825.1) but lower combined medical and medication costs ($47,412.50 vs $52,761.50, 95% CI: 801.5, 9896.40). CONCLUSIONS While biologic treatments are costly, patients initiating biologics sooner after diagnosis appear to have better HCRU outcomes and require fewer healthcare resources at 1-2 years post-index, potentially leading to overall cost savings.

Abstract
Delayed diagnosis is a challenge in the management of inflammatory bowel disease (IBD). Several studies show a significant association between diagnostic delay and disease progression to complications and surgery, especially in Crohn's disease (CD). What risk factors are associated with diagnostic delay in IBD remains unclear. In order to reduce diagnostic delay, the Red Flags Index has been developed and validated. The combination of the Red Flags Index score and non-invasive biomarkers such as fecal calprotectin seems to be highly accurate in screening patients with underlying IBD to be referred for further diagnostic workup and eventual early effective treatment strategies. Our literature review aims to obtain a comprehensive overview of the impacts of diagnostic delay in IBD on the potential risk factors associated with IBD, how diagnostic tools may be effective in reducing diagnostic delay, and future perspectives in this field.

Abstract
Non-caseating granulomas may indicate a more aggressive phenotype of Crohn disease (CD). Genetic associations of granulomatous CD (GCD) may help elucidate disease pathogenesis. Whole-exome sequencing was performed on peripheral blood-derived DNA from 17 pediatric patients with GCD and 19 with non-GCD (NGCD), and from an independent validation cohort of 44 GCD and 19 NGCD cases. PLINK (a tool set for whole-genome association and population-based linkage analyses) analysis was used to identify single nucleotide polymorphisms (SNPs) differentiating between groups, and subgroup allele frequencies were also compared to a public genomic database (gnomAD). The Combined Annotation Dependent Depletion scoring tool was used to predict deleteriousness of SNPs. Human leukocyte antigen (HLA) haplotype findings were compared to a control group (n = 8496). PLINK-based analysis between GCD and NGCD groups did not find consistently significant hits. gnomAD control comparisons, however, showed consistent subgroup associations with DGKZ , ESRRA , and GXYLT1 , genes that have been implicated in mammalian granulomatous inflammation. Our findings may guide future research and precision medicine.

Abstract
Innate lymphoid cells (ILCs) are considered innate counterparts of adaptive T cells; however, their common and unique transcriptional signatures in pediatric inflammatory bowel disease (pIBD) are largely unknown. Here, we report a dysregulated colonic ILC composition in pIBD colitis that correlates with inflammatory activity, including accumulation of naive-like CD45RA+CD62L- ILCs. Weighted gene co-expression network analysis (WGCNA) reveals modules of genes that are shared or unique across innate and adaptive lymphocytes. Shared modules include genes associated with activation/tissue residency, naivety/quiescence, and antigen presentation. Lastly, nearest-neighbor-based analysis facilitates the identification of "most inflamed" and "least inflamed" lymphocytes in pIBD colon with unique transcriptional signatures. Our study reveals shared and unique transcriptional signatures of colonic ILCs and T cells in pIBD. We also provide insight into the transcriptional regulation of colonic inflammation, deepening our understanding of the potential mechanisms involved in pIBD.

Abstract
OBJECTIVES Pediatric inflammatory bowel disease (IBD) is a complex inflammatory condition of the gut. Diagnosing IBD involves distinct longitudinal periods from first symptoms to primary care assessment, tertiary care referral, and then endoscopic confirmation. The term diagnostic delay (DD) is used if these periods are prolonged. The aim of this review was to amalgamate DD data for children with IBD, and identify factors associated with prolonged DD. METHODS Six health literature databases were searched (December 2020). Inclusion criteria for papers were children diagnosed with IBD before the age of 18 years, DD central tendency data, and to report a central tendency of their DD data, cohort >10 children. For analysis, all data were weighted by cohort sample size. RESULTS Searches identified 236 papers, and 26 were included in the final analysis with a pooled cohort of 7030 children. The overall DD periods were IBD 4.5 months [Interquartile range (IQR) 3.6-8.7 months], Crohn disease (CD) 5 months (IQR 4-7.2 months), and ulcerative colitis/indeterminate colitis/IBD-unclassified (UC/IC/IBDU) 3 months (IQR 2.2-4.9 months). The difference between subtypes was significant ( P < 0.001), with shorter DD for UC/IC/IBDU than CD ( P < 0.001) and IBD ( P < 0.001). DD periods were longer for CD than IBD ( P < 0.001). DD decreased over time for IBD ( P < 0.001) and UC ( P < 0.001) but the trend suggested an increase for CD ( P 0.069). CONCLUSIONS This data can be used to benchmark DD for children with IBD. Individual centers could determine whether improvements to awareness or infrastructure may reduce DD in order to minimize the risk of poor outcomes.

Systematic review with meta-analysis: Time to diagnosis and the impact of delayed diagnosis on clinical outcomes in inflammatory bowel disease. Aliment Pharmacol Ther 2023; 57:635-652. [PMID: 36627691 DOI: 10.1111/apt.17370] [Citation(s) in RCA: 33] [Impact Index Per Article: 33.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/29/2022] [Accepted: 12/10/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND The impact of diagnostic delay on the clinical course of inflammatory bowel disease (IBD) remains uncertain. AIM To perform a systematic review of time to diagnosis and the impact of delayed diagnosis on clinical outcomes in Crohn's disease (CD) and ulcerative colitis (UC). METHODS We searched EMBASE and Medline from inception to 30th November 2022 for studies reporting diagnostic interval, from symptom onset to IBD diagnosis. We calculated the median, interquartile range (IQR) and pooled weighted median, of median diagnostic intervals of eligible studies. We defined delayed diagnosis as individuals above the 75th centile of longest time to diagnosis in each study. Using random effects meta-analysis, we pooled odds ratios (ORs) with 95% confidence intervals (CI) for studies reporting clinical outcomes, according to delayed diagnosis. RESULTS One hundred and one studies representing 112,194 patients with IBD (CD = 59,359; UC = 52,835) met inclusion criteria. The median of median times to diagnosis was 8.0 (IQR: 5.0-15.2) and 3.7 months (IQR: 2.0-6.7) in CD and UC, respectively. In high-income countries, this was 6.2 (IQR: 5.0-12.3) and 3.2 months (IQR: 2.2-5.3), compared with 11.7 (IQR: 8.3-18.0) and 7.8 months (IQR: 5.2-21.8) in low-middle-income, countries, for CD and UC respectively. The pooled weighted median was 7.0 (95% CI: 3.0-26.4) and 4.6 (95% CI: 1.0-96.0) months, for CD and UC respectively. Eleven studies, representing 6164 patients (CD = 4858; UC = 1306), were included in the meta-analysis that examined the impact of diagnostic delay on clinical outcomes. In CD, delayed diagnosis was associated with higher odds of stricturing (OR = 1.88; CI: 1.35-2.62), penetrating disease (OR = 1.64; CI: 1.21-2.20) and intestinal surgery (OR = 2.24; CI: 1.57-3.19). In UC, delayed diagnosis was associated with higher odds of colectomy (OR = 4.13; CI: 1.04-16.40). CONCLUSION Delayed diagnosis is associated with disease progression in CD, and intestinal surgery in both CD and UC. Strategies are needed to achieve earlier diagnosis of IBD.

Abstract
BACKGROUND Pediatric inflammatory bowel disease (IBD) is increasingly prevalent, but diagnosis can still be challenging. Diagnostic delay is particularly deleterious in this age group. OBJECTIVE This study explores the evolution of diagnostic delay in pediatric IBD and the influence of the COVID-19 pandemic. METHODS Retrospective study including all pediatric IBD patients diagnosed during 2014, 2019 and 2020 in a tertiary hospital. Diagnostic delay, time to first medical visit, time to pediatric gastroenterologist (PG) visit and time to diagnosis were calculated and compared within a gap of five years (2019 and 2014) and with the year of onset of the pandemic (2020 and 2019). RESULTS A total of 93 participants were included (2014: 32, 2019: 30, 2020: 31). No significant differences were observed in diagnostic delay, time to first medical visit in Crohn's disease (CD), time to PG visit and time to diagnosis when comparing 2019-2014 and 2020-2019. Time to first visit in ulcerative colitis (UC) and Undetermined-IBD increased in 2019 (P=0.03), with new decrease in 2020 (P=0.04). Diagnostic delay was longer in DC compared to UC plus Undetermined-IBD. CONCLUSION Diagnostic delay is still an important matter in pediatric IBD, with no significant change over the last years. The time to the first PG visit and the time for diagnosis seem to have the greatest impact on diagnostic delay. Thus, strategies to enhance recognition of IBD symptoms among first-line physicians and to improve communication, facilitating referral, are of utmost importance. Despite the restraints in the health care system caused by the pandemic, time to diagnosis in pediatric IBD was not impaired during 2020 in our center.

Abstract
INTRODUCTION Delays in diagnosing pediatric inflammatory bowel disease (IBD) are common, but the extent of this delay remains unclear due to variations in reported time-periods between studies. The objectives of this systematic review were to examine the extent of diagnostic delay in pediatric IBD and examine any association between specific characteristics and length of diagnostic delay. METHODS We identified studies from several medical bibliographical databases (EMBASE, Medline and CINAHL) from their inception to April 2021. Studies examining pediatric cohorts (< 18 years old) defined as having a diagnosis of Crohn's Disease (CD), ulcerative colitis (UC), or by the more general definition of IBD, and reporting a median time-period between the onset of symptoms and a final diagnosis (diagnostic delay) were included. Two reviewers selected each study, extracted data, and assessed their quality using the Newcastle-Ottawa scale. Narrative synthesis was then used to examine the extent of overall diagnostic delay and delay associated with specific sample characteristics. RESULTS Of the 10,119 studies initially identified, 24 were included in the review. The overall median diagnostic delay range was 2-10.4 months for IBD, 2.0-18.0 months for UC and 4.0-24.0 months for CD. However, for approximately two thirds of UC (68.8%) and CD (66.7%) studies, delay ranged from 2.0-3.0 and 4.0-6.3 months, respectively. A longer delay was significantly associated with several sample characteristics; however, these were too infrequently examined to draw robust conclusion on their role. CONCLUSION Children continue to wait several months for a final diagnosis of IBD, and those with CD experience longer delay than those with UC. The role of specific characteristics on delay needs further exploration.

Abstract
BACKGROUND The identification of early prognostic factors during Crohn's disease (CD) remains needed for physician decision-making to minimize structural bowel damage, which this study aimed to assess in a population-based setting. METHODS All incident cases of CD were prospectively registered from 1994 to 1997 in Brittany, a limited area of France. All charts of patients were reviewed from the diagnosis to the last clinic visit in 2015. Disabling CD course was defined according to the Saint-Antoine criteria. RESULTS Among the 331 incident cases of CD, 272 (82%) were followed-up for a median time of 12.8 years. The cumulative probability of developing stricturing or fistulizing CD was 66% at 15 years, and 107 (39%) patients underwent surgery. The cumulative probabilities of immunosuppressant and TNF antagonist use at 15 years were 37% and 22%, respectively. The cumulative risks for disabling disease and bowel damage were 74% and 71% at 15 years, respectively. Systemic symptoms and perianal lesions at diagnosis were independently associated with a disabling disease course. Perianal disease and short disease extension were associated with the onset of bowel damage. Deep ulcers was not predictive of any outcome. CONCLUSIONS A disabling disease course and bowel damage occurred early in the course of CD, which suggests the need for early diagnosis and early treatment, particularly for patients with systematic symptoms and perianal disease.

Abstract
OBJECTIVES Disparities in health care for racial/ethnic minority children in the United States who are burdened by pediatric Crohn's disease (PCD) are not well understood. METHODS A retrospective review of the Texas Children's Hospital ImproveCareNow database from 2007 to 2015 was performed. CD patients with a minimum of 2-year follow-up were included if the onset of symptoms attributable to inflammatory bowel disease was clearly documented. We primarily aimed to identify race and ethnicity associations in diagnostic delay, presentation, treatment, and 2-year outcomes. We also examined early versus late diagnosis (ie, over 6 months from disease onset) associations with these variables unrelated to race/ethnicity. RESULTS One hundred and sixty-six PCD patients [57.8% non-Hispanic White (NH-White), 18.1% African American (AA), and 15.7% Hispanic] met selection criteria. Time to diagnosis was shorter in Hispanic patients ( P < 0.01) and they were older at diagnosis than NH-White patients ( P = 0.0164). AA patients (33%, P < 0.01) and Hispanic patients (35%, P < 0.05) had lower rates of granuloma detection than NH-White patients (63%). AA patients had lower rates of steroid-free remission (SFR) at 2 years than NH-White patients ( P < 0.05). Higher ESR and lower hemoglobin levels were associated with early diagnosis ( P < 0.01). Early diagnosis was associated with higher rates of surgery within 2 years of diagnosis ( P < 0.05). Diagnostic fecal calprotectin levels inversely associated with SFR at 2 years ( P < 0.05). Early use of biologics positively, and early use of corticosteroids negatively correlated with 2-year SFR ( P < 0.05). CONCLUSIONS Race and ethnicity may influence the diagnosis, treatment, and outcomes of PCD. This recognition presents a nidus toward establishing equity in PCD care.

Abstract
Diagnostic delays (time from the first symptoms to diagnosis) are common in inflammatory bowel disease (IBD) and may lead to worse disease progression and treatment outcomes. This study aimed to determine the duration of diagnostic delays (DD) and to explore associated factors in a cohort of children with IBD in New Zealand. In this study, patients with IBD diagnosed as children and their parents/caregivers completed questionnaires on the patients’ medical history, diagnostic experience, and demographic characteristics. The parent/caregiver questionnaire also included the Barriers to Care Questionnaire (BCQ). Patients’ healthcare data was reviewed to summarise the history of clinical visits and determine symptoms. Total DD, healthcare DD, patient DD and parent DD were derived from the primary dataset. Factors associated with the different types of DD were explored with a series of simple linear and logistical ordinal regressions. A total of 36 patients (Crohn’s disease 25, ulcerative colitis 10; male 17) were included. They were diagnosed at a median age of 12 years (interquartile range (IQR) 10−15 years). Total healthcare delay (from first healthcare visit to formal diagnosis) was median (IQR) 15.4 (6.5−34.2) months. The median (IQR) specialist-associated delay was 4.5 (0−34) days. Higher household income was associated with shorter healthcare delay (p < 0.018), while lower overall BCQ scores (indicating more barriers experienced) were associated with longer total healthcare DD. Higher scores in each subscale of BCQ (Skills; Pragmatics; Expectations; Marginalization; Knowledge and Beliefs) were also significantly associated with shorter total healthcare delay (p < 0.04). This study found substantial diagnostic delays in paediatric patients with IBD and identified significant associations between longer total healthcare diagnostic delays and overall household income and higher self-reported barriers to accessing healthcare.

Abstract
BACKGROUND/OBJECTIVES We analyzed the nationwide pediatric inflammatory bowel disease (PIBD) registry (1998-2016), to evaluate the nutritional status at the time of diagnosis. SUBJECTS/METHODS Nine types of nutritional status by the combination of weight-for-length (<2 years)/body mass index (>2 years) and length/height-for-age with three categories (<-2, -2 to 2, and >2 SD) were described. Malnutrition was defined by WHO criteria. Univariate and multivariate regression analysis was used to identify risk factors for malnutrition. RESULTS In total, 824 IBD patients (498 Ulcerative colitis (UC); 289 Crohn's Disease (CD); 37 Indeterminate Colitis (IC); 412 male; the median age 12.5 years) were eligible. The prevalence of eutrophy, wasting/thinness, stunting, overweight, tall stature, concurrent wasting/thinness and stunting, tall stature with overweight, tall stature with wasting/thinness, and short stature with overweight were 67.4%, 14.9%, 6.6%, 3.1%, 3.2%, 3.3%, 1.1%, 0.4%, and 0.1%, respectively. The prevalence of malnutrition was 32.7%, indicating a higher prevalence in CD (p < 0.001). Incidence of overweight was less common in the CD than UC and IC (p < 0.001). Multivariate analysis revealed that age of onset (>10 years), prepubertal stage, severe disease activity, perianal involvement, and high C reactive protein level were independently associated with malnutrition in pediatric IBD. CONCLUSION We showed the frequency of nutritional impairment in PIBD. The percentage of overweight subjects was lower than the other studies. The age of onset, disease activity, CRP level, perianal involvement, and pubertal stage were associated with a higher risk for developing malnutrition. Our results also confirmed that CD patients are particularly vulnerable to nutritional impairment. CLINICAL TRIAL NUMBER ClinicalTrials.gov Identifier: NCT04457518.

Abstract
Inflammatory bowel diseases [IBD] such as Crohn's disease [CD] and ulcerative colitis [UC] are complex conditions presenting with a wide range of phenotypes. Given major variation in disease severity and outcomes as well as response to existing therapies, a personalised treatment approach stands the chance of improving the overall disease outcome as well as minimising potentially harmful side effects. However, disease activity or distribution at the point of diagnosis are poor predictors of future disease outcome. Hence, the urgent need to develop biomarkers that could either predict the overall disease course [i.e., disease prognostic biomarkers] or the response to individual therapies [i.e., disease predictive biomarkers]. Despite the widely accepted need for such biomarkers to improve the management of IBD patients, their development has proven to be challenging for a number of reasons. Based on our own experience in this field, we perform a reality check on existing evidence, discuss main challenges, and outline future perspectives.

Abstract
BACKGROUND AND AIMS The significance of different ages of perianal disease (PD) onset in patients with perianal Crohn's disease (PCD) remains unknown. We aimed to investigate the impact of paediatric-onset PD (POP) and adult-onset PD (AOP) on the Crohn's disease (CD) course in a Chinese cohort. METHODS The medical records of diagnosed PCD patients from 2008 to 2018 were reviewed retrospectively. The cumulative incidence and predictors of intestinal resection were calculated using the Kaplan-Meier and logistic regression analysis. RESULTS Complex perianal fistulas (71.7% vs 50.0%, p = 0.011) and infliximab (IFX) treatment (33.3% vs 22.0%, p = 0.044) were more common among the POP patients (age < 18 years old, n = 84). A younger PD onset age (15.1 ± 2.9 vs 30.2 ± 10.5 years, p < 0.001) and shorter PCD diagnostic delay (12 vs 24 months, p = 0.033) was found in the POP cohort. AOP patients (age ≥ 18 years old, n = 209) had a higher rate of current smoking (12.9% vs 4.8%, p = 0.040), stricturing behaviour (42.1% vs 27.4%, p = 0.024) and intestinal resection (21.1% vs 4.8%, p = 0.001). The cumulative probability of intestinal resection in AOP patients was higher than that in POP patients (p = 0.007). In multivariable analysis, AOP (OR: 4.939, 95% CI 1.538-15.855, p = 0.007), stricturing behaviour (OR: 1.810, 95% CI 1.008-3.251, p = 0.047) and rectal inflammation (OR: 3.166, 95% CI 1.119-8.959, p = 0.030) were predictive factors for CD-related intestinal resection in all PCD patients. AOP patients with complex perianal fistula (OR: 2.257, 95% CI 1.041-4.891, p = 0.039) and POP patients with rectal inflammation (OR: 3.166, 95% CI 1.119-8.959, p = 0.030) were more likely to suffer intestinal resection. The IFX administration significantly decreased the rate of intestinal resection in AOP patients (r = - 0.900, p = 0.037). CONCLUSIONS The AOP patients have more complicated luminal disease and higher rate of intestinal resection than COP patients. The perianal diseases onset-age can provide clinical treatment guidance for individual management of CD patients.

Abstract
BACKGROUND Undelayed diagnosis is thought to be a major determinant for good prognosis in pediatric inflammatory bowel disease (PIBD). However, factors predicting diagnostic delay and the consequences of this remain poorly defined. We investigated these issues in a well-defined cohort of PIBD patients. METHODS Comprehensive electronic data were collected from 136 PIBD patients retrospectively. Diagnostic delay was further classified into < 6 and ≥ 6 months, and < 12 and ≥ 12 months. Logistic regression was used to calculate whether the delay was associated with clinical features and/or risk of complications and co-morbidities at diagnosis. RESULTS The median age of patients was 12.4 years and 43.4% were females. Altogether 35.5% had Crohn´s disease (CD), 59.1% ulcerative colitis (UC) and 6.6% IBD undefined (IBD-U). The median delay before diagnosis was 5.0 months in all, 6.6 months in CD, 4.1 months in UC, and 9.8 months in IBD-U (UC vs. CD, p = 0.010). In all but IBD-U most of the delay occurred before tertiary center referral. Abdominal pain predicted a delay > 6 months in all PIBD (OR 2.07, 95% CI 1.00-4.31) and in UC patients (3.15, 1.14-8.7), while bloody stools predicted a shorter delay in all PIBD (0.28, 0.14-0.59) patients and in CD (0.10, 0.03-0.41) patients. A delay > 6 months was associated with a higher frequency of complications (2.28, 1.01-5.19). CONCLUSIONS Delay occurred mostly before specialist consultation, was longer in children presenting with abdominal pain and in CD and was associated with risk of complications. These findings emphasize the roles of active case-finding and prompt diagnostic evaluations.

Abstract
BACKGROUND AND AIMS Crohn's disease (CD) can lead to work disability with social and economic impacts worldwide. In Brazil, where its prevalence is increasing, we assessed the indirect costs, prevalence, and risk factors for work disability in the state of Rio de Janeiro and in a tertiary care referral center of the state. METHODS Data were retrieved from the database of the Single System of Social Security Benefits Information, with a cross-check for aid pension and disability retirement. A subanalysis was performed with CD patients followed up at the tertiary care referral center using a prospective CD database, including clinical variables assessed as possible risk factors for work disability. RESULTS From 2010 to 2018, the estimated prevalence of CD was 26.05 per 100,000 inhabitants, while the associated work disability was 16.6%, with indirect costs of US$ 8,562,195.86. Permanent disability occurred more frequently in those aged 40 to 49 years. In the referral center, the prevalence of work disability was 16.7%, with a mean interval of 3 years between diagnosis and the first benefit. Risk factors for absence from work were predominantly abdominal surgery, anovaginal fistulas, disease duration, and the A2 profile of the Montreal classification. CONCLUSIONS In Rio de Janeiro, work disability affects one-sixth of CD patients, and risk factors are associated with disease duration and complications. In the context of increasing prevalence, as this disability compromises young patients after a relatively short period of disease, the socioeconomic burden of CD is expected to increase in the future.

Abstract
Inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis, are chronic, progressive, immune-mediated diseases of adults and children that have no cure. IBD can cause significant morbidity and lead to complications such as strictures, fistulas, infections, and cancer. In children, IBD can also result in growth impairment and pubertal delays. IBD is highly heterogenous, with severity ranging from mild to severe and symptoms ranging from mild to debilitating. Delay in IBD diagnosis, especially in Crohn's disease, is common and associated with adverse outcomes. Early diagnosis and prompt institution of treatment are the cornerstones for improving outcomes and maximizing health. Early diagnosis requires a low threshold of suspicion and red flags to guide early specialist referral at the primary provider level. Although the armamentarium of IBD medications is growing, many patients will not respond to treatment, and the selection of first-line therapy is critical. Risk stratification of disease severity, based on clinical, demographic, and serologic markers, can help guide selection of first-line therapy. Clinical decision support tools, genomics, and other biomarkers of response to therapy and risk of adverse events are the future of personalized medicine. After starting appropriate therapy, it is important to confirm remission using objective end points (treat to target) with continued control of inflammation with adjustment of therapy using surrogate biomarkers (tight control). Lastly, IBD therapy extends far beyond medications, and other aspects of the overall health and wellbeing of the patient are critical. These include preventive health, nutrition, and psychobehavioral support addressing patients' concerns around complementary therapy and medication adherence, prevention of disability, and ensuring open communication.

Abstract
OBJECTIVES The efficacy of infliximab in treatment-naïve patients with stricturing small bowel Crohn's disease (CD) has not been well studied. We aimed to evaluate the efficacy of infliximab in these patients. MATERIALS AND METHODS This was a retrospective study of all consecutive treatment-naïve patients with newly diagnosed CD with small bowel stricture who started regular infliximab therapy in Nanfang Hospital between January 2015 and December 2019. An effective infliximab therapy was defined as infliximab continuation without the use of steroids, new biologics, endoscopic interventions or intestinal surgery. RESULTS Seventy-nine patients were included. After a median 38 months follow-up, an effective infliximab therapy was achieved in 37 patients. Long diagnostic delay (hazard ratio [HR] 0.38, 95% confidence interval [CI] 0.19-0.78; p= .008), pre-stenotic dilatation (HR 0.17, 95%CI 0.09-0.35; p < .001), long segmental stricture (HR 0.20, 95%CI 0.10-0.41; p < .001), and penetrating disease (HR 0.22, 95%CI 0.10-0.49; p < .001) were negatively correlated with an effective infliximab therapy. CONCLUSIONS Infliximab is effective in nearly 50% of treatment-naïve patients with CD with small bowel stricture, and an effective therapy is more likely to be achieved in patients without long diagnostic delay, pre-stenotic dilatation, long segmental stricture or penetrating disease.

Effectiveness of Infliximab on Deep Radiological Remission in Chinese Patients with Perianal Fistulizing Crohn's Disease. Dig Dis Sci 2021; 66:1658-1668.

Abstract
BACKGROUND AND AIMS Information concerning deep radiological healing of perianal fistulas in Chinese patients with CD is limited. The present study aimed to establish the effectiveness of infliximab on CD-related perianal fistulas using magnetic resonance imaging (MRI) and identify predictors of deep radiological remission of fistulas. METHODS We retrospectively reviewed patients with CD with draining perianal fistulas treated with infliximab and included only those who underwent clinical assessment and MRI before and after infliximab therapy. RESULTS Among 178 patients who underwent repeated MRI and clinical assessment, 65.2% had complex fistulas. Post-infliximab therapy, 55.1% of patients with perianal fistulizing CD showed clinical remission and 26.4% presented a clinical response; 38.2% had deep radiological remission, and 34.3% had a partial response based on the Ng score; the Van Assche scores decreased obviously compared with baseline. Prolonged infliximab infusion (18 times) presented higher radiological remission rates in patients with CD with complex fistulas. Concomitant treatment with azathioprine increased the fistula healing rate compared with infliximab alone (50% vs. 36.9%, P < 0.001). Younger age at diagnosis of CD, proctitis and requiring perianal surgery were identified as predictors of poor deep radiological remission of fistulas. Eight of ten patients who stopped infliximab and switched to an alternative agent retained a status of fistula healing in the first year of follow-up. CONCLUSIONS Infliximab induced deep radiological remission of perianal fistulas in Chinese patients with CD. Routine MRI should be used to monitor fistula healing. Patients with younger age at diagnosis of CD, proctitis, and/or requiring perianal surgery should receive combined therapy and careful monitoring.

Abstract
BACKGROUND Using Infliximab early in Crohn's disease can provide a window of opportunity in children for restoration of growth and achievement of puberty. We aimed to compare clinical outcomes and costs of a retrospective pediatric Crohn's disease (pCD) cohort treated with early use Infliximab (EUI) within 12 months compared with later use Infliximab (LUI). METHODS Retrospective review of all children with pCD commenced on Infliximab was undertaken in a tertiary Australian pediatric center. RESULTS pCD progressing to Infliximab was identified in 70 children: 38 (54%) in the EUI cohort versus 32 (46%) in the LUI cohort. Intestinal surgery had a higher risk of occurring in EUI when compared with LUI (2 (5%) versus 9 (28%), HR 5.67 (95% CI 1.21-26.38); p = .027). No patients in EUI underwent intestinal surgery post Infliximab commencement compared with 3 (9%) in LUI (p = .09). Escalation of Infliximab in luminal Crohn's disease was not significantly different in EUI when compared with LUI (3 (10.3%) versus 9 (39.1%) (p = .1)). EUI was more frequently used than LUI in 2015-2018 (27 (71%) versus 14 (44%)) p = .029, with the inverse occurring in 2010-2014 (11 (29%) versus 18 (56%)). Hospital admissions per person per year in EUI and LUI were 43 (0.23 visits/person/year) versus 84 (0.67 visits/person/year); IRR 2.51 (95% CI 0.9-7.01); p = .078). Health costs were not significantly different between cohorts. CONCLUSION EUI in pCD is associated with an increased likelihood of being diagnosed in more recent years, less intestinal surgery and a trend toward decreased hospital admissions than LUI.

Abstract
We report the case of a 63-year-old female patient with liver cirrhosis who presented with symptoms of severe hypoalbuminaemia and diarrhoea. After ruling out other causes of hypoalbuminaemia and confirmation of an elevated faecal α-1 antitrypsin clearance, the diagnosis of protein-losing enteropathy (PLE) could be established. Since PLE is a syndrome caused by various diseases, classified into erosive and non-erosive gastrointestinal diseases or lymphatic obstruction, an extensive work-up was necessary, establishing the final diagnosis of Crohn's disease.

Abstract
Background Clinicians aim to prevent progression of Crohn’s disease (CD); however, many patients require surgical resection because of cumulative bowel damage. The aim of this study was to evaluate the impact of early intervention on bowel damage in patients with CD using the Lémann Index and to identify bowel resection predictors.
Methods We analyzed consecutive patients with CD retrospectively. The Lémann Index was determined at the point of inclusion and at follow-up termination. The Paris definition was used to subdivide patients into early and late CD groups. Results We included 154 patients, comprising 70 with early CD and 84 with late CD. After follow-up for 17.0 months, more patients experienced a decrease in the Lémann Index (61.4% vs. 42.9%), and fewer patients showed an increase in the Lémann Index (20% vs. 35.7%) in the early compared with the late CD group. Infliximab and other therapies reversed bowel damage to a greater extent in early CD patients than in late CD patients. Twenty-two patients underwent intestinal surgery, involving 5 patients in the early CD group and 17 patients in the late CD group. Three independent predictors of bowel resection were identified: baseline Lémann index ≥ 8.99, disease behavior B1, and history of intestinal surgery. Conclusions Early intervention within 18 months after CD diagnosis could reverse bowel damage and decrease short-term intestinal resection. Patients with CD with a history of intestinal surgery, and/or a Lémann index > 8.99 should be treated aggressively and monitored carefully to prevent progressive bowel damage.

Abstract
BACKGROUND Paediatric data on the association between diagnostic delay and inflammatory bowel disease [IBD] complications are lacking. We aimed to determine the effect of diagnostic delay on stricturing/fistulising complications, surgery, and growth impairment in a large paediatric cohort, and to identify predictors of diagnostic delay. METHODS We conducted a national, prospective, multicentre IBD inception cohort study including 1399 children. Diagnostic delay was defined as time from symptom onset to diagnosis >75th percentile. Multivariable proportional hazards [PH] regression was used to examine the association between diagnostic delay and stricturing/fistulising complications and surgery, and multivariable linear regression to examine the association between diagnostic delay and growth. Predictors of diagnostic delay were identified using Cox PH regression. RESULTS Overall (64% Crohn's disease [CD]; 36% ulcerative colitis/IBD unclassified [UC/IBD-U]; 57% male]), median time to diagnosis was 4.2 (interquartile range [IQR] 2.0-9.2) months. For the overall cohort, diagnostic delay was >9.2 months; in CD, >10.8 months and in UC/IBD-U, >6.6 months. In CD, diagnostic delay was associated with a 2.5-fold higher rate of strictures/internal fistulae (hazard ratio [HR] 2.53, 95% confidence interval [CI] 1.41-4.56). Every additional month of diagnostic delay was associated with a decrease in height-for-age z-score of 0.013 standard deviations [95% CI 0.005-0.021]. Associations persisted after adjusting for disease location and therapy. No independent association was observed between diagnostic delay and surgery in CD or UC/IBD-U. Diagnostic delay was more common in CD, particularly small bowel CD. Abdominal pain, including isolated abdominal pain in CD, was associated with diagnostic delay. CONCLUSIONS Diagnostic delay represents a risk factor for stricturing/internal fistulising complications and growth impairment in paediatric CD.

Extraintestinal Manifestations and Other Comorbidities in Ulcerative Colitis and Crohn Disease: A Danish Nationwide Registry Study 2003-2016. CROHN'S & COLITIS 360 2020; 2:otaa070.

Abstract
Background Extraintestinal manifestations (EIMs) in inflammatory bowel disease (IBD) may be a frequent complication to an underlying abnormal immune response. This study investigated the occurrence of EIMs in Crohn disease (CD) and ulcerative colitis (UC) patients using population-based data in Denmark from 2003 to 2016. Methods In this national registry-based study, incident CD and UC patients between 2003 and 2015 were matched on age and gender with non-IBD controls and followed until 2016. The selected EIMs for this study included 51 different diagnoses divided into biological systems of diseases, which were tested for differences in the timing and occurrence of EIMs. Results The study cohort included 10,302 patients with CD and 22,144 patients with UC. The highest risk of patients experiencing EIM/comorbidities for the first time before their IBD diagnosis was in the skin and intestinal tract systems. For CD, the odds ratio of having an EIM before or after IBD diagnosis, as compared with controls, was significant in the skin, intestinal tract, hepatopancreatobiliary, musculoskeletal, ocular, renal, and respiratory systems. For UC, the risks were similar before and after UC diagnosis, apart from the nervous system where the odds ratio was significantly higher before the diagnosis of UC, and significantly lower after diagnosis for diseases in the ocular system. Conclusions EIMs in CD and UC patients may also precede their IBD diagnosis. These findings may indicate a significant diagnostic delay of CD and UC, and the occurrence of known EIMs should prompt physicians to look for patients possibly having underlying IBD.

Abstract
Crohn's disease and ulcerative colitis have emerged as global diseases. They affect over 2 million individuals in the North America, 3.2 million in Europe, and millions more worldwide. The recent decades have been characterized by several important changes in the epidemiology of these diseases, in particularly an increasing incidence rates in newly industrialized countries experiencing a westernization of lifestyle. While rates of surgery have experienced a temporal decline attributable in part to increasing availability of medical treatments, earlier initiation of effective therapy, and changes in clinical practice, the healthcare costs associated with these diseases have continued to increase, in part due to costly therapies. Robust epidemiologic and experimental studies have defined the role of the external environment and microbiome on disease pathogenesis and have offered opportunities for disease prevention by modifying such factors. We propose several important steps that are necessary to provide globally sustainable inflammatory bowel disease care in the 21st century.

Abstract
Paediatric inflammatory bowel disease is not very common in Spain. Its onset can be silent and an early diagnosis reduces complications and sequelae related to the disease, and can improve the prognosis. It is advisable to define the different intervals into which the time until the diagnosis is divided, as well as the peculiarities and conditions in order to be able to act on them and, to avoid, as far as possible, the diagnostic delay. The aim of this review is to provide tools to reduce the time to diagnosis.
