[PMID: 35703262 DOI: 10.1097/mcg.0000000000001729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 05/15/2022] [Indexed: 12/10/2022]
Abstract
BACKGROUND AND GOALS Perianal Crohn's disease (pCD) represents an aggressive phenotype with limited studies on long-term outcomes. We evaluated 5-year outcomes of these patients on biologic therapies. METHODS We performed a retrospective analysis of patients with pCD at a tertiary medical center. We used Kaplan-Meier curves to estimate rates and multivariate logistic regression to identify predictors of long-term outcomes. RESULTS We included 311 patients with pCD of which 168 patients were started on biologics [138 anti-tumor necrosis factor (TNF) α, 14 vedolizumab, 16 ustekinumab] at the time of diagnosis. Anti-TNF use at the time of diagnosis was associated with decreased rates of perianal abscess recurrence [hazard ratio (HR)=0.48, 95% confidence interval (CI): 0.32-0.74], whereas ustekinumab use was associated with increased rates of perianal fistula closure (HR=3.58, 95% CI: 1.04-12.35) and decreased rates of perianal abscess recurrence (HR=0.20, 95% CI: 0.07-0.56) at follow-up. Among patients who failed their first anti-TNF, switching to another anti-TNF was associated with decreased rates of colectomy (HR=0.20, 95% CI: 0.04-0.90) and permanent diversion (HR=0.16, 95% CI: 0.03-0.94) compared with ustekinumab, whereas vedolizumab use was associated with decreased perianal fistula closure (HR=0.22, 95% CI: 0.05-0.96) compared with ustekinumab. Predictors of colectomy included colonic disease (odds ratio=2.71, 95% CI: 1.36-5.38) and anal stenosis (odds ratio=4.44, 95% CI: 1.59-12.43). CONCLUSION Type of biologic use at the time of pCD diagnosis or after first anti-TNF failure may be associated with long-term outcomes in patients with pCD.

Abstract
BACKGROUND We aimed to develop criteria for treatment intensification in patients with (1) luminal Crohn's disease (CD), (2) CD with perianal disease and/or fistula, (3) CD with small bowel stenosis, (4) in the postoperative setting, and (5) for discontinuing or reducing the dose of treatment in patients with CD. METHODS PubMed and Embase were searched for studies published since 1998 which may be relevant to the five defined topics. Results were assessed for relevant studies, with preference given to data from randomized, controlled studies. For each question, a core panel of 12 gastroenterologists defined the treatment target and developed statements, based on the literature, current guidelines, and relevant additional studies. The evidence supporting each statement was graded using the Oxford Centre for Evidence-Based Medicine: Levels of Evidence (March 2009). A modified Delphi process was used to refine statements and gain agreement from 54 Japanese specialists at in-person and online meetings conducted between October 2020 and April 2021. RESULTS Seventeen statements were developed for treatment intensification in luminal CD (targeting endoscopic remission), six statements for treatment intensification in perianal/fistulizing CD (targeting healing of perianal lesions and complete closure of the fistula), six statements for treatment intensification in CD with small bowel stenosis (targeting resolution of obstructive symptoms), seven statements for treatment intensification after surgery (targeting endoscopic remission), and five statements for discontinuing or reducing the dose of treatment in patients with CD. CONCLUSIONS These statements provide guidance on how and when to intensify or de-intensify treatment for a broad spectrum of patients with CD.

Abstract
Inflammatory bowel disease (IBD) refers to a group of disorders, including Crohn's disease and ulcerative colitis, that exhibit similar but distinct manifestations. These diseases are characterized by refractory and chronic inflammation of the bowel. IBD is usually accompanied by severe symptoms. When a patient presents with suspected IBD, physicians encounter various challenges in terms of diagnosis and treatment. In addition, given such characteristics, the associated medical expenses gradually increase. Although IBD was formerly known as a disease of Western countries, the incidence and prevalence are increasing in Korea. Korean investigators have accumulated a great deal of knowledge about the regional characteristics and epidemiology of the disease, especially via well-organized, joint cohort studies. Against this background, this article describes the epidemiology of IBD in Korea compared to that in the West. In addition, an overview of the pathophysiology of the disease is provided, focusing on the latest results.

Abstract
The burden of inflammatory bowel disease (IBD) in Asia has been increasing over the past decades. Although patients with IBD show heterogenous phenotypes depending on the individual characteristics, no significant differences have been established in the IBD phenotypes of Western and Asian populations. However, despite the much lower incidence of IBD in Asia than in Western countries, the incidence has been rapidly increasing in Asia while remaining stable in Western countries. The incidence of ulcerative colitis (UC) showed an earlier and a more marked increase than the incidence of Crohn disease (CD), but the UC-to-CD ratio has recently decreased because of a relative increase in the incidence of CD in Asia. While CD shows a significant male predominance, UC only shows a slight male predominance. A recent study reported that the incidence of IBD in Asia showed a bimodal age distribution with increasing IBD prevalence, similar to the findings of Western studies. CD in Asian patients, especially those in East Asia, is characterized by ileocolonic involvement and perianal fistula. The frequency of extraintestinal manifestations, including primary sclerosing cholangitis, appears to be lower in Asia, but this finding should be interpreted with caution due to the transient and nonspecific nature of these manifestations. Although familial aggregation is lower in East Asia, it may also be explained by the low prevalence of IBD in Asia. Thus, more studies should focus on the differences in phenotypes in Asian IBD patients versus Western patients.

Perianal disease onset age is associated with distinct disease features and need for intestinal resection in perianal Crohn's disease: a ten-year hospital-based observational study in China. BMC Gastroenterol 2021; 21:376. [PMID: 34649523 PMCID: PMC8515669 DOI: 10.1186/s12876-021-01961-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 10/08/2021] [Indexed: 11/10/2022] Open
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/Aims The long-term course of Crohn’s disease (CD) has never been evaluated in non-Caucasian population-based cohorts. The aim of the present study was to evaluate the long-term prognosis of Korean CD patients in the well-defined population-based Songpa-Kangdong inflammatory bowel disease cohort. Methods Outcomes of disease and their predictors were evaluated for 418 patients diagnosed with CD between 1986 and 2015. Results During a median of 123 months, systemic corticosteroids, thiopurines, and anti-tumor necrosis factor (TNF) agents were administered to 58.6%, 81.3%, and 37.1% of patients, respectively. Over time, the cumulative probability of starting corticosteroids significantly decreased (p=0.001), whereas that of starting thiopurines and anti-TNFs significantly increased (both p<0.001). The cumulative probability of behavioral progression was 54.5% at 20 years, and it significantly decreased during the anti-TNF era. Intestinal resection was required for 113 patients (27.0%). The cumulative probabilities of intestinal resection at 1, 5, 10, 20, and 25 years after CD diagnosis were 12.7%, 16.5%, 23.8%, 45.1%, and 51.2%, respectively. Multivariable Cox regression analysis identified stricturing behavior at diagnosis (adjusted hazard ratio [aHR], 2.70; 95% confidence interval [CI], 1.55 to 4.71), penetrating behavior at diagnosis (aHR, 11.15; 95% CI, 6.91 to 17.97), and diagnosis of CD during the anti-TNF era (aHR, 0.51; 95% CI, 0.35 to 0.76) as independently associated with intestinal resection. The standardized mortality ratio among CD patients was 1.36 (95% CI, 0.59 to 2.68). Conclusions The long-term prognosis of Korean patients with CD is at least as good as that of Western CD patients, as indicated by the low intestinal resection rate. Moreover, behavioral progression and intestinal resection rates have decreased over the past 3 decades.

Abstract
BACKGROUND AND AIM The clinical impact of perianal Crohn's disease (CD) (pCD), a well-known poor prognostic factor of CD, has not been fully evaluated in Asian patients. We investigated the outcomes of CD in Korean patients according to the presence of pCD at CD diagnosis. METHODS Using 2010-2014 data from the national health insurance claims database, we evaluated the disease course of CD according to the presence of pCD at CD diagnosis. The results were verified in a hospital-based cohort of 2923 patients. RESULTS The cumulative risk of intestinal resection was lower in patients with pCD at diagnosis than in those without, in the population-based cohort (9.1% vs 14.7% at 5 years after diagnosis, P < 0.001), but it was similar between the two groups in the hospital-based cohort (36.8% vs 36.8% at 10 years after diagnosis, P = 0.950). Moreover, the cumulative risk of behavioral progression was not significantly different between the two groups in the hospital-based cohort (43.4% vs 41.6% at 10 years after diagnosis, P = 0.366). On multivariable analysis, pCD at CD diagnosis was not a predictor of intestinal resection, behavioral progression, CD-related hospital admission, or diverting surgery; however, it was an independent predictor of proctectomy (hazard ratio [HR] 3.210, P < 0.001) and anorectal cancer (HR 3.104, P = 0.047). CONCLUSIONS Although the presence of pCD increased the risk of proctectomy and anorectal cancer in Asian patients, the clinical impact of pCD on the overall outcomes of patients with CD may be less significant in Asian patients compared with Western patients.

Gut Liver 2021; 15:851-857.

Abstract
Background/Aims Recently, the treatment of Crohn’s disease (CD) has changed to a treat-to-target strategy, in which disease progression is prevented with early intervention. We analyzed the long-term evolution of nonstricturing, nonpenetrating (B1) disease at diagnosis and factors related to disease evolution in pediatric CD. Methods We retrospectively analyzed 402 patients between 2000 and 2013 who were younger than 18 years and had B1 disease at CD diagnosis. The median follow-up was 6.1 years (range, 1 to 13 years). The cumulative probabilities of developing stricturing (B2) or penetrating (B3) disease and associations between risk factors and disease behavior evolution were evaluated. Results Among the 402 patients, 75 (18.7%) had B2 or B3 disease by the final follow-up. The cumulative probabilities of disease behavior evolution were 18.3%, 34.3%, and 50.9% at 5, 10, and 13 years, respectively. Patients whose disease progressed had an increased risk of intestinal resection (hazard ratio [HR], 3.61; 95% confidence interval [CI], 2.25 to 6.03; p<0.001). First-degree family history of inflammatory bowel disease (HR, 2.38; 95% CI, 1.07 to 5.28; p=0.032), isolated ileal involvement at diagnosis (HR, 7.55; 95% CI, 1.04 to 15.57; p=0.045), and positive anti-Saccharomyces cerevisiae antibody titers (HR, 2.10; 95% CI, 1.03 to 4.25; p=0.040) were associated with disease behavior evolution. Early treatment with biologics significantly reduced disease progression (HR, 0.46; 95% CI, 0.79 to 3.39; p=0.042). Conclusions This study suggests that early aggressive therapy should be considered in B1 behavior pediatric CD patients with risk factors of disease evolution to improve long-term outcomes.

Objectives: The incidence of Crohn's disease and the number of associated surgeries are increasing in Korea. This study investigated the effect of azathioprine/6-mercaptopurine (6-MP) and TNF-α antagonists on abdominal and perianal surgery in Korean patients with Crohn's disease. Design: A retrospective cohort study. Setting: Data from the Crohn's Disease Clinical Network and Cohort (CONNECT) were used. Patients with confirmed Crohn's disease between 1982 and 2008 from 32 hospitals in the Republic of Korea were enrolled. The effect of azathioprine/6-MP on abdominal and perianal surgery was analysed using logistic regression analysis adjusting for age and sex. Participants: In total, 1161 Crohn's disease patients were included in the Republic of Korea in the surgery (n = 462, male = 339, female = 123) and control groups (n = 699, male = 484, female = 215). Results: In total, 1161 patients were selected, with 462 patients who underwent abdominal (n = 245) or perianal surgery (n = 217). The preoperative usage rates of azathioprine/6-MP were 18.8% and 65.1% (p < 0.0001) in the surgery and control groups, respectively. The preoperative usage rates of TNF-α antagonists were 7.1% and 23.3% (p < 0.0001) in the surgery and control groups, respectively. A multivariate analysis revealed that the preoperative use of azathioprine/6-MP had an odds ratio of 0.094 for all surgeries (95% confidence interval [CI]: 0.070-0.127, p < 0.0001), 0.131 for abdominal surgery (95% CI: 397-1.599, p < 0.0001), and 0.059 for perianal surgery (95% CI: 0.038-0.091, p < 0.0001). The preoperative use of TNF-α antagonists had an odds ratio of 0.225 for all surgeries (95% CI: 0.151-0.335, p < 0.0001), 0.403 for abdominal surgery (95% CI: 0.261-0.623, p < 0.0001), and 0.064 for perianal surgery (95% CI: 0.026-0.160, p < 0.001). Strengths of this study: The study presents new evidence of the reduced risk of surgery following azathioprine use in Crohn's disease patients. Limitations of this study (1) This was not a controlled prospective study. (2) There was a selection bias specific to the CONNECT cohort. (3) The combination or sequential use of azathioprine/6-MP and TNF-α antagonists was not excluded. Conclusion: Azathioprine/6-MP is significantly associated with a reduced risk of abdominal and perianal surgery in Korean patients with Crohn's disease.

Abstract
BACKGROUND Perianal disease is associated with a disabling course of Crohn's disease (CD). We aim to study the impact of perianal disease on CD remission rates, after a 1-year course of infliximab in combination therapy with azathioprine. METHODS This was a retrospective, single-center cohort study, including consecutive CD patients on combination therapy, followed for 1 year since induction. The outcome variable was split into clinical and endoscopic remissions. The correlation toward the outcome variable was assessed with univariate and multivariate analysis and a survival assessment, using SPSS software. RESULTS We assessed 74 CD patients, of whom 41 (55.4%) were female, with a mean age of 36 years. Thirty-nine percent of the patients presented perianal disease at diagnosis (n = 29). We documented 70.3% clinical and 47.2% endoscopic remissions. Several variables had statistical significance toward the outcomes (endoscopic and clinical remissions) in the univariate analysis. After adjusting for confoundment, patients with perianal disease presented an odds ratio (OR) of 0.201 for achieving endoscopic remission (CI: 0.054-0.75, p value 0.017) and an OR of 0.203 for achieving clinical remission (CI: 0.048-0.862, p value 0.031). Sixty-six patients (89.2%) presented an initial response to treatment, from whom, 20 (30.3%) exhibited at least 1 disease relapse (clinical and/or endoscopic). Patients with perianal disease presented higher probability of disease relapse, displaying statistically significant difference on Kaplan-Meier curves (Breslow p value 0.043). CONCLUSION In the first year of combination therapy, perianal disease is associated with an 80% decrease in endoscopic and clinical remission rates and higher ratio of disease relapse.

Abstract
Mucosal healing (MH) is the goal of the “treat to target” strategy in Crohn's disease (CD), which seeks to prevent disability. However, evidence is limited regarding whether achieving MH can reduce disability in CD. We aimed to estimate the probability of disabling disease and to investigate the association between MH and disabling disease in CD.

Association of Perianal Fistulas with Clinical Features and Prognosis of Crohn's Disease in Korea: Results from the CONNECT Study. Gut Liver 2019; 12:544-554. [PMID: 30037171 PMCID: PMC6143449 DOI: 10.5009/gnl18157] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2018] [Revised: 06/13/2018] [Accepted: 06/19/2018] [Indexed: 12/15/2022] Open
Abstract
Background/Aims The disease course and factors associated with poor prognosis in Korean patients with Crohn’s disease (CD) have not been fully determined. The aim of this study was to explore potential associations between the clinical characteristics and long-term outcomes of CD and perianal fistulas in a Korean population. Methods The retrospective Crohn’s Disease Clinical Network and Cohort (CONNECT) study enrolled patients diagnosed with CD between July 1982 and December 2008 from 32 hospitals. Those followed for <12 months were excluded. Clinical outcomes were CD-related surgery and complications, including nonperianal fistulas, strictures, and intra-abdominal abscesses. Results The mean follow-up period was 8.77 years (range, 1.0 to 25.8 years). A total of 1,193 CD patients were enrolled, of whom 465 (39.0%) experienced perianal fistulas. Perianal fistulizing CD was significantly associated with younger age, male gender, CD diagnosed at primary care clinics, and ileocolonic involvement. Both nonperianal fistulas (p=0.034) and intra-abdominal abscesses (p=0.020) were significantly more common in CD patients with perianal fistulas than in those without perianal fistulas. The rates of complicated strictures and CD-related surgery were similar between the groups. Independently associated factors of nonperianal fistulas were perianal fistulas (p=0.015), female gender (p=0.048), CD diagnosed at referral hospital (p=0.003), and upper gastrointestinal (UGI) involvement (p=0.001). Furthermore, perianal fistulas (p=0.048) and UGI involvement (p=0.012) were independently associated with the risk of intra-abdominal abscesses. Conclusions Perianal fistulas predicted the development of nonperianal fistulas and intra-abdominal abscesses in Korean CD patients. Therefore, patients with perianal fistulizing CD should be carefully monitored for complicated fistulas or abscesses.
