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.

[PMID: 38414786 PMCID: PMC10895587 DOI: 10.3892/etm.2024.12414] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 11/24/2023] [Indexed: 02/29/2024] Open
Abstract
Paeoniflorin (PF) is the primary component derived from Paeonia lactiflora and white peony root and has been used widely for the treatment of ulcerative colitis (UC) in China. UC primarily manifests as a chronic inflammatory response in the intestine. In the present study, a network pharmacology approach was used to explore the specific effects and underlying mechanisms of action of PF in the treatment of UC. A research strategy based on network pharmacology, combining target prediction, network construction, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and molecular docking simulation was used to predict the targets of PF. A total of 288 potential targets of PF and 599 UC-related targets were identified. A total of 60 therapeutic targets of PF against UC were identified. Of these, 20 core targets were obtained by protein-protein interaction network construction. GO and KEGG pathway analyses showed that PF alleviated UC through EGFR tyrosine kinase inhibitor resistance, the IL-17 signaling pathway, and the PI3K/AKT signaling pathway. Molecular docking simulation showed that AKT1 and EGFR had good binding energy with PF. Animal-based experiments revealed that the administration of PF ameliorated the colonic pathological damage in a dextran sulfate sodium-induced mouse model, resulting in lower levels of proinflammatory cytokines including IL-1β, IL-6, and TNF-α, and higher levels of IL-10 and TGF-β. PF decreased the mRNA and protein expression levels of AKT1, EGFR, mTOR, and PI3K. These findings suggested that PF plays a therapeutic protective role in the treatment of UC by regulating the PI3K/AKT signaling pathway.

Abstract
AIM Biologic therapies have been associated with reduced rate of colectomy in ulcerative colitis (UC) in adults, but data are limited in paediatric-onset UC. Our aim was to define the rate of colectomy in paediatric-onset UC, including post-transition into adult care, and to evaluate the impact of biologic therapies on rate of colectomy. METHOD All prevalent patients diagnosed with paediatric-onset UC in South-East Scotland were identified from a prospectively accrued database at our regional tertiary centre. Patients exposed to biologics or surgery were identified and further data collected from health records. Kaplan-Meier analysis was used to calculate cumulative risk of colectomy over time. RESULTS 145 prevalent patients were identified between 2000 and 2021. Median follow-up was 7.9 years (IQR 4.1-13.1). 23 patients (16 %) underwent a colectomy. 50/145 (34 %) patients received biologic therapy, and 13/23 (57 %) patients who underwent colectomy received biologics. The cumulative risk of colectomy across the whole cohort at 1, 5, and 10 years was 3 %, 13 % and 16 %, respectively. Patients exposed to biologics had a higher colectomy rate at 5 and 10 years (22 % and 34 %). Patients in the pre-biologic era (2000-2008) had non-significantly reduced time from diagnosis to colectomy (2.4 vs 3.7 years, p = 0.204). CONCLUSION We have defined the 1-, 5-, and 10-year colectomy rate in a population-based cohort of Paediatric-onset UC patients. Patients who received biologic therapy had a significantly increased risk of colectomy. Increased severity of disease in these patients may account for the greater colectomy risk.

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.

Abstract
PURPOSE The aim of this study was to describe our initial surgical and functional outcomes of transanal ileal pouch anastomosis (Ta-IPAA) in adolescents. METHODS A total of 16 adolescents' age ≤ 19 underwent consecutive Ta-IPAA on the indication ulcerative colitis (UC) or familiar adenomatous polyposis (FAP), between January 2018 and September 2022. Primary outcomes were postoperative complications. Secondary outcomes were conversion rates, intraoperative complications, length of hospital stay (LOS), morbidity within 30 days, surgical characteristics, and functional outcomes. RESULTS Thirteen adolescents with UC and three with FAP underwent Ta-IPAA. The median age of UC patients was 16. They had a colectomy on the indication UC followed by a Ta-IPAA. Median operating time was 247 min, and there were no conversion or intraoperative complications. Median LOS was 7 days. No anastomotic leakage was observed, and three patients had complications within the first 30 days. Three had late complications. The median bowel movements were 5, and 50% had bowel movements during the night. Three children were operated on the indication FAP with proctocolectomy and Ta-IPAA. There were no conversion or intraoperative complications, and the median bowel movements was 4. CONCLUSION Ta-IPAA approach in children seems to be feasible, safe and offers acceptable functional results.

Diagnostic Delay in Pediatric Inflammatory Bowel Disease: A Systematic Review. Dig Dis Sci 2022; 67:5444-5454.

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
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
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 Develop a clinical and biological predictive model for colectomy risk in children newly diagnosed with ulcerative colitis (UC). METHODS This was a multicenter inception cohort study of children (ages 4-17 years) newly diagnosed with UC treated with standardized initial regimens of mesalamine or corticosteroids (CS) depending upon initial disease severity. Therapy escalation to immunomodulators or infliximab was based on predetermined criteria. Patients were phenotyped by clinical activity per the Pediatric Ulcerative Colitis Activity Index (PUCAI), disease extent, endoscopic/histologic severity, and laboratory markers. In addition, RNA sequencing defined pretreatment rectal gene expression and high density DNA genotyping by the Affymetrix UK Biobank Axiom Array. Coprimary outcomes were colectomy over 3 years and time to colectomy. Generalized linear models, Cox proportional hazards multivariate regression modeling, and Kaplan-Meier plots were used. RESULTS Four hundred twenty-eight patients (mean age 13 years) started initial theapy with mesalamine (n = 136), oral CS (n = 144), or intravenous CS (n = 148). Twenty-five (6%) underwent colectomy at ≤1 year, 33 (9%) at ≤2 years, and 35 (13%) at ≤3 years. Further, 32/35 patients who had colectomy failed infliximab. An initial PUCAI ≥ 65 was highly associated with colectomy (P = 0.0001). A logistic regression model predicting colectomy using the PUCAI, hemoglobin, and erythrocyte sedimentation rate had a receiver operating characteristic area under the curve of 0.78 (95% confidence interval [0.73, 0.84]). Addition of a pretreatment rectal gene expression panel reflecting activation of the innate immune system and response to external stimuli and bacteria to the clinical model improved the receiver operating characteristic area under the curve to 0.87 (95% confidence interval [0.82, 0.91]). CONCLUSIONS A small group of children newly diagnosed with severe UC still require colectomy despite current therapies. Our gene signature observations suggest additional targets for management of those patients not responding to current medical therapies.

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.
