Abstract
Crohn's disease (CD) and ulcerative colitis (UC), two major subtypes of inflammatory bowel disease, show substantial differences in their clinical course and treatment response. To identify the genetic factors underlying the distinct characteristics of these two diseases, we performed a genome-wide association study (GWAS) between CD (n = 2359) and UC (n = 2175) in a Korean population, followed by replication in an independent sample of 772 CD and 619 UC cases. Two novel loci were identified with divergent effects on CD and UC: rs9842650 in CD200 and rs885026 in NCOR2. In addition, the seven established susceptibility loci [major histocompatibility complex (MHC), TNFSF15, OTUD3, USP12, IL23R, FCHSD2 and RIPK2] reached genome-wide significance. Of the nine loci, six (MHC, TNFSF15, OTUD3, USP12, IL23R and CD200) were replicated in the case-case GWAS of European populations. The proportion of variance explained in CD-UC status by polygenic risk score analysis was up to 22.6%. The area under the receiver-operating characteristic curve value was 0.74, suggesting acceptable discrimination between CD and UC. This CD-UC GWAS provides new insights into genetic differences between the two diseases with similar symptoms and might be useful in improving their diagnosis and treatment.

Impact of Sarcopenia on Clinical Course of Inflammatory Bowel Disease in Korea. Dig Dis Sci 2023; 68:2165-2179. [PMID: 36693962 DOI: 10.1007/s10620-023-07838-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 01/13/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND AND AIMS Reduced body muscle mass is a poor prognostic factor for inflammatory bowel disease (IBD). In this study, we investigated the prevalence of sarcopenia at diagnosis and its clinical significance in Korean patients with IBD. METHODS The prevalence of sarcopenia in IBD patients between June 1989 and December 2016 was investigated using a well-characterized referral center-based cohort. Abdominopelvic computed tomography within six months from IBD diagnosis was used for the evaluation. Sarcopenia was defined as an L3 skeletal muscle index of < 49 cm2/m2 for male and < 31 cm2/m2 for female. The clinical characteristics and outcomes were evaluated with respect to sarcopenia. RESULTS A total of 1,027 patients (854 Crohn's disease [CD]; 173 ulcerative colitis [UC]) were evaluated. Sarcopenia was found in 56.8% of the population (CD, 57.5%; UC, 53.2%), and male were more likely to be sarcopenic (CD, 94.3%; UC, 91.6%). There were no significant differences in the cumulative risk of using steroids, immunomodulators, biologics, and bowel resections (or colectomy) with or without sarcopenia during follow-up (median: CD, 5.8 years; UC, 3.7 years). In sarcopenic patients with CD, there was a significantly higher cumulative risk of perianal surgeries than in non-sarcopenic patients with CD (Log-rank test; P = 0.001). However, the risk of perianal surgeries was not significant in multivariate analysis (Odds ratio 1.368; 95% confidence interval 0.782-2.391; P = 0.272). CONCLUSION Sarcopenia at diagnosis may have no significant prognostic value for medical treatment and bowel resection, but it may be associated with perianal CD.

Abstract
BACKGROUND Surgical management in Ulcerative Colitis (UC) is typically utilised in medically refractory cases and, therefore, it is a useful marker for efficacy of medical management. AIMS To understand the changing prevalence of colectomy in UC over time. METHODS A systematic review was conducted using MEDLINE (1946-2021), EMBASE and EMBASE classic (1947-2021) to identify studies with a population of n>500 that reported colectomy rates in UC patients >18 years old. The primary outcome was the prevalence of colectomy at 1-, 5- and 10-years post-diagnosis. Secondary outcomes included colectomy rates in the pre-biologics (defined as pre-2004) and post-biologics eras (defined as post-2004). RESULTS Thirty-one studies with 294,359 patients with UC were included for review and meta-analysis. The prevalence of colectomy at 1-, 5- and 10-years post-diagnosis were 3% (95% CI 2%-6%), 5% (95% CI 2%-9%), 10% (95% CI 6%-16%) respectively. The pooled relative risk for colectomy in the post-biologics era was 0.68 (95% CI 0.42 to 1.09, p=0.10) at 1-year and 0.71 (95% CI 0.56 to 0.91, p<0.01) at 5-years post-diagnosis. CONCLUSION The overall colectomy rate has decreased over the past three decades. Biologics may have played a role in reducing the risk of colectomy, however the relative risk reduction is likely to be modest.

Abstract
BACKGROUND AND AIMS Few population-based studies have investigated the long-term colectomy rates of ulcerative colitis (UC). We aimed to assess the colectomy rates over 40 years of different therapeutic eras in a prospective population-based inception cohort from Veszprem Province, Western Hungary. METHODS Patient inclusion lasted between January1,1977, and December31, 2018. Patient follow-up ended December 31,2020. Colectomy rates and disease course were examined in three different eras based on the time of UC diagnosis; cohort-A(1977-1995),cohort-B(1996-2008), and cohort C(2009-2018). RESULTS A total of 1,370 incident UC patients were included (male 51.2%,median age at diagnosis:37 years). Median follow-up was 17 years (IQR 9-24); 87 patients(6.4%) underwent colectomy. The cumulative probability of colectomy in the total population was 2.6%(95%CI 2.2-3.0), 4.2%(95%CI 3.6-4.8), 7.0%(95%CI 6.2-7.8), and 10.4%(95%CI 9.1-11.7) after 5, 10, 20, and 30 years, respectively. The proportion of extensive colitis at diagnosis increased over time (24.2%/24.3%/34.9% in cohorts A/B/C,p=0.001). Overall exposure to immunomodulators (11.3%/20.9%/34.4% in cohorts A/B/C,p<0.001), as well as the probability for biological therapy initiation increased over time; 0%/ 3.3%(95%CI 2.6-4.0)/ 13.9%(95%CI 12.1-15.7), p<0.001. There were no statistically significant differences in the cumulative probability of colectomies between cohorts A/B/C; 1.7% (95%CI 1.0-2.4), 2.5%(95%CI 1.9-3.1), and 3.7%(95%CI 2.7-4.7) after 5 years; 3.5%(95%CI 2.5-4.5), 4.2%(95%CI 3.4-5.0), and 4.5%(95%CI 3.3-5.7) after 10 years; and 7.5% (95%CI 6.1-8.9) and 6.3% (95%CI 5.2-7.4) in cohorts A/B after 20 years (Log-rank=0.588). Extensive colitis (HR;2.24:95%CI 1.55-3.23) and continuous active disease activity (HR;6.36:95%CI 3.46-11.67) were independent predictors for colectomy. CONCLUSION No differences in colectomy rates have been observed in the incident UC patients over 40 years despite increasing use of immunomodulators and biological therapies.

Abstract
Background The quality of life of persons living with inflammatory bowel disease (IBD) is impacted by the physical and psychosocial burdens of disease, as well as by their satisfaction with the quality of care they receive. We sought to better understand (1) the drivers of satisfaction with treatment, including treatment goals, treatment selection, and attributes of patient/health care professional (HCP) interactions, and (2) how IBD symptoms affect aspects of daily life and overall quality of life. Methods Two online questionnaires were accessed via MyCrohnsAndColitsTeam.com. The Treatment Survey assessed desired treatment outcomes, past and present therapies, and experiences with the patient's primary treating HCP. The Quality of Life survey assessed respondents' most problematic IBD symptoms and their influence on family and social life, work, and education. Respondents had Crohn's disease (CD) or ulcerative colitis (UC), were 19 years or older, and resided in the United States. All responses were anonymous. Results The Treatment Experience survey was completed by 502 people (296 CD, 206 UC), and the Quality of Life survey was completed by 302 people (177 CD, 125 UC). Reduced pain, diarrhea, disease progression, and fatigue were the most desired goals of treatment. Biologics and 5-aminosalicylates were reported as a current or past treatment by the greatest proportion of patients with CD and UC, respectively. A numerically lower proportion of respondents with UC than CD reported use of biologic or small molecule therapy; conversely, a numerically greater proportion of respondents with UC than CD reported these drugs to be very or extremely effective. The HCP was key in the decision to switch to, and in the selection of, biologic or small molecule therapy. Overall satisfaction with an HCP was greatly driven by the quality and quantity of the communication and of the time spent with the HCP. Troublesome abdominal symptoms most impacted aspects of social and family life. Emotional challenges associated with IBD were experienced by most respondents. Conclusions Treatment goals of respondents seem to align with HCPs overall treatment goals, including control of gastrointestinal symptoms and prevention of disease progression. Persons with UC might be offered biologic and small molecule therapies less often, despite reported high efficacy by users. Feeling heard and understood by the HCP are key drivers of treatment satisfaction. Quality communication in the patient/HCP relationship enables a better understanding of the patients' goals, disease burden, and emotional needs, which are all key factors to consider when developing a personalized and comprehensive treatment plan and optimizing quality of life.

Abstract
BACKGROUND We investigated the real-life effectiveness and safety of vedolizumab (VDZ) induction therapy among Korean patients with Crohn disease (CD) or ulcerative colitis (UC) for whom anti-tumor necrosis factor therapy previously failed. METHODS Adult patients who started VDZ induction therapy at 16 centers were prospectively enrolled in the Korean VDZ nationwide registry. The coprimary outcomes were clinical remission, defined as a Crohn's Disease Activity Index score <150 points and a partial Mayo score ≤2 points with a combined rectal bleeding and stool frequency subscore ≤1 point at week 14 and endoscopic remission defined as a Mayo endoscopic subscore ≤1 point. We also analyzed predictors of clinical remission. RESULTS Between August 2017 and November 2019, a total of 158 patients (80 with CD and 78 with UC) received VDZ induction therapy. Clinical remission rates among patients with CD and patients with UC were 44.1% and 44.0%, respectively. Among patients with UC, the endoscopic remission rate was 32.4%. Clinical response and remission rates showed increasing trends during induction therapy. Multivariable analysis revealed that clinical response at week 6 was the only predictor of clinical remission at week 14 for both patients with CD and patients with UC. Among patients who experienced 1 or more adverse events (n = 71; 44.9%), disease exacerbation (n = 28; 17.7%) was the most common adverse event. CONCLUSIONS Among Korean patients with CD or UC for whom anti-tumor necrosis factor therapy failed, VDZ induction therapy was effective and safe. The early clinical response was associated with clinical remission after VDZ induction therapy.

Insufficient vaccination and inadequate immunization rates among Korean patients with inflammatory bowel diseases. Medicine (Baltimore) 2021; 100:e27714. [PMID: 34766576 PMCID: PMC10545296 DOI: 10.1097/md.0000000000027714] [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: 01/19/2021] [Revised: 08/02/2021] [Accepted: 10/20/2021] [Indexed: 11/26/2022] Open
Abstract
ABSTRACT This study aimed to evaluate self-reported vaccination rates, immunity, knowledge of and attitudes toward vaccination among Korean patients with inflammatory bowel disease (IBD) as well as to identify factors associated with proper vaccination.Between November 2013 and February 2015, consecutive patients with IBD were invited to complete a standardized questionnaire on vaccination. Moreover, immune status for common vaccine-preventable diseases was evaluated via serologic tests.A total of 310 patients with IBD were invited to the questionnaire survey and 287 patients (92.6%) who completed the questionnaires were finally enrolled (men, 188 [65.5%], median age at survey, 29.9 years [interquartile range, 22.3-39.2], ulcerative colitis: Crohn disease = 165:122]. Self-reported vaccine uptake rates were as follows: hepatitis A virus (HAV; 13.2%), hepatitis B virus (HBV; 35.2%), seasonal influenza (43.2%), pneumococcus (4.9%). Most of the patients (87.1%) did not know that proper vaccination has been recommended for patients with IBD. Up to 64.8% and 32.8% of patients were negative for IgG anti-HAV antibody and IgG HBV surface antibody, respectively. In a multivariable analysis, newspaper subscription (aOR [adjusted odds ratio] 2.185, 95% confidence interval [CI] 1.136-4.203, P = .019), ever recommendation of vaccination by a physician (aOR 2.456, 95% CI 1.240-4.862, P = .010), and use of anti-tumor necrosis factor agents (aOR 4.966, 95% CI 1.098-22.464, P = .037) showed a significant association with uptake of adult vaccines recommended for patients with IBD.Vaccine uptake rates, positivity of antibody to HAV and HBV, and knowledge of patients with IBD regarding vaccination were not sufficient. Proper educational information and recommendation from physicians could enhance awareness among patients with IBD about the need for vaccination and thereby improve vaccination rates.Trial registration number: NCT01984879.

Early Changes in Serum Albumin Predict Clinical and Endoscopic Outcomes in Patients With Ulcerative Colitis Starting Anti-TNF Treatment. Inflamm Bowel Dis 2021; 27:1452-1461. [PMID: 33269403 DOI: 10.1093/ibd/izaa309] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Up to 60% of patients with ulcerative colitis (UC) ultimately fail anti-tumor necrosis factor (TNF) treatment. We aimed to investigate early predictive markers of clinical and endoscopic outcomes in patients with UC who were anti-TNF-naïve commencing anti-TNF treatment, with particular focus on changes in albumin and C-reactive protein levels in the first 2 weeks of treatment. METHODS We retrospectively investigated 210 patients with UC who started infliximab or adalimumab between 2009 and 2016 (male, 62.4%; median age at diagnosis, 37.9 years [interquartile range, 25.5-48.9 years]; median follow-up duration, 3.3 years [1.9-5.0 years]). Logistic and Cox proportional-hazards regressions were performed to identify variables associated with primary nonresponse (PNR), endoscopic outcomes, time-to-colectomy, and anti-TNF failure. RESULTS Forty-one patients (19.5%) experienced PNR; week 0/week 2 ratio serum albumin was associated with PNR (adjusted odds ratio [aOR], 1.8; 95% confidence interval [CI], 1.1-2.9, per interquartile range increase). Week 0/week 2 ratio albumin was also associated with endoscopic response (aOR, 0.28; 95% CI, 0.31-0.82) and endoscopic remission (aOR, 0.61; 95% CI, 0.39-0.96) at weeks 8 to 14, time-to-colectomy (adjusted hazard ratio, 2.12; 95% CI, 1.29-3.49) and time-to-anti-TNF failure (adjusted hazard ratio, 1.54; 95% CI, 1.22-1.96), regardless of age, disease severity, or in-patient status. Association with time-to-colectomy and anti-TNF failure was externally validated in an independent cohort of inpatients with UC starting infliximab. CONCLUSIONS Change in serum albumin within the first 2 weeks of anti-TNF treatment is predictive of PNR, endoscopic outcomes, time-to-colectomy, and anti-TNF failure in patients with UC. Timely access to this biomarker enables early identification of patients with UC at risk of anti-TNF failure and may guide early optimization of anti-TNF treatment to improve disease outcomes.

Abstract
METHODS We retrospectively reviewed the medical records of IBD patients who visited Asan Medical center. We used a large, well-characterized referral center-based cohort. The clinical features of IBD patients with body mass index (BMI) over 30 and matched controls with BMI under 30 were compared. RESULTS Among the 6,803 IBD patients enrolled in the Asan IBD Registry between June 1989 and December 2016, we identified 16 patients with Crohn's disease (CD) and 27 patients with ulcerative colitis (UC) whose BMI was over 30 at the time of diagnosis. Their clinical characteristics and course were compared with those of 64 and 108 matched patients with CD and UC, respectively. There were no significant differences in the risk of using steroids (hazards ratio (HR) = 0.633 and P=0.254), immunomodulators (HR = 0.831 and P=0.517), and anti-tumor necrosis factor (TNF) therapy (HR = 1.539 and P=0.351) and risk of bowel resections (HR = 1.858 and P=0.231) between CD patients with BMI over 30 and those with BMI under 30; similarly, UC patients did not show significant differences in the risk of using steroids (HR = 0.613 and P=0.145), immunomodulators (HR = 0.492 and P=0.111), anti-TNF therapy (HR = 0.385 and P=0.095), and risk of colectomy (HR = 0.262 and P=0.104). In the subgroup analysis, under-weight UC patients had a higher cumulative probability of needing steroids (HR = 0.2510 and P=0.042), needing immunomodulators (HR = 0.097 and P=0.014), and a higher risk of receiving colectomy (HR = 0.024 and P=0.019) than obese UC patients. CONCLUSIONS Obese IBD patients with CD or UC did not show significantly different clinical features from nonobese IBD patients.

Abstract
Background/Aims Although pediatric ulcerative colitis (UC) has a different phenotype and clinical course than adult UC, its clinical features and outcomes are poorly defined, especially in Asian populations. This study investigated the clinical features and long-term outcomes of pediatric UC in a Korean population. Methods We retrospectively analyzed 208 patients aged <18 years diagnosed with UC between 1987 and 2013. The patient characteristics at diagnosis according to the Paris classification and the clinical course were analyzed. Results The male-to-female ratio was 1.3:1, and the median patient age was 15.5 years. At diagnosis, 28.8% of patients had proctitis (E1), 27.8%, left-sided colitis (E2); 5.2%, extensive colitis (E3); and 38.2%, pancolitis (E4). The cumulative probabilities of extension after 5, 10, 15, and 20 years were 32.7%, 40.4%, 52.5%, and 65.8%, respectively. Eighteen patients underwent colectomy, and three patients had colorectal cancer. The cumulative probabilities of colectomy after 5, 10, 15, and 20 years were 7.1%, 8.9%, 12.6%, and 15.6%, and those of colorectal cancer after 10, 15, and 20 years were 0%, 2.1%, and 12.0%, respectively. The disease extent, Pediatric Ulcerative Colitis Activity Index severity, and systemic corticosteroid therapy were significant risk factors for colectomy. The development of primary sclerosing cholangitis was significantly associated with colorectal cancer. Conclusions This study provides detailed information on the disease phenotype and long-term clinical outcomes in a large cohort of Korean children with UC. They have extensive disease at diagnosis, a high rate of disease extension, and a low rate of cumulative colectomy.

Dig Dis Sci 2021; 66:587-596. [PMID: 32219610 DOI: 10.1007/s10620-020-06207-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Accepted: 03/10/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Previous studies have shown vitamin D status to be associated with disease activity in patients with inflammatory bowel disease (IBD), but its influence on the clinical course of IBD has not been established. AIMS We aimed to analyze whether the serum 25-hydroxyvitamin D3 [25(OH)D] status is associated with clinical characteristics and affects the risk of surgery in patients with IBD. METHODS From the IBD registry of the Asan Medical Center, we identified all patients who had at least one 25(OH)D measurement; we then analyzed the association between clinical factors and 25(OH)D status. 25(OH)D was considered borderline deficient, deficient, and severely deficient at levels of < 30, < 20, and < 10 ng/mL, respectively. RESULTS We included 711 Crohn's disease (CD) and 764 ulcerative colitis (UC) patients who had not undergone surgery before 25(OH)D was measured. Both in CD and in UC patients, reduced 25(OH)D was associated with higher disease activity scores and CRP levels (p < 0.001). Severe 25(OH)D deficiency was associated with ileocolonic disease and complicated behavior in CD (p < 0.05) and was relevant to the disease extent in UC (p < 0.001). Additionally, severe 25(OH)D deficiency was associated with CMV colitis in patients with UC (p < 0.001). In multivariable analysis, severe deficiency of 25(OH)D was an independent risk factor for surgery in both CD (HR 1.93, 95% confidence interval [CI] 1.38-2.70) and UC (HR 2.77, 95% CI 1.14-6.74). CONCLUSION Severe 25(OH)D deficiency may be a marker of a more aggressive clinical course of IBD.

Prevalence and risk factors of bowel symptoms in Korean patients with ulcerative colitis in endoscopic remission: a retrospective study. BMC Gastroenterol 2021; 21:13. [PMID: 33407193 PMCID: PMC7789344 DOI: 10.1186/s12876-020-01597-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 12/28/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Many patients with ulcerative colitis (UC) in clinical remission frequently complain of bowel symptoms such as increased stool frequency (SF) and rectal bleeding (RB). However, studies on these patient-reported outcomes in patients with inactive UC are limited, especially in Korea. Therefore, we investigated the prevalence and risk factors of bowel symptoms in Korean patients with inactive UC. METHODS We investigated the prevalence of bowel symptoms in patients with endoscopically quiescent UC between June 1989 and December 2016 using a well-characterized referral center-based cohort. The Mayo clinic score (MCS) was used to evaluate bowel symptoms at the most recent visit near the date of endoscopy. Clinical characteristics of the patients were compared based on the presence or absence of bowel symptoms. RESULTS Overall, 741 patients with endoscopically quiescent UC were identified, of whom 222 (30%) and 48 (6.5%) had an SF and RB subscore of ≥ 1, respectively. Patients with bowel symptoms (SF + RB ≥ 1; n = 244 [32.9%]) had higher rates of left-sided colitis (E2) or extensive colitis (E3) than patients without bowel symptoms (SF + RB = 0; n = 497 [67.1%]; P = 0.002). Multivariate analysis revealed that female sex (odds ratio [OR]: 1.568; 95% confidence interval [CI]: 1.023-2.402; P = 0.039) and E2 or E3 (OR 1.411; 95% CI 1.020-1.951; P = 0.038) were the significant risk factors for increased SF. CONCLUSIONS This study revealed that one-third of patients with endoscopically quiescent UC reported increased SF. Female sex and disease extent may be associated with bowel symptoms.

Abstract
OBJECTIVE No population-based study has evaluated the natural course of UC over three decades in non-Caucasians. We aimed to assess the long-term natural course of Korean patients with UC in a population-based cohort. DESIGN This Korean population-based, Songpa-Kangdong IBD cohort included all patients (n=1013) newly diagnosed with UC during 1986-2015. Disease outcomes and their predictors were evaluated. RESULTS During the median follow-up of 105 months, the overall use of systemic corticosteroids, thiopurines and antitumour necrosis factor (anti-TNF) agents was 40.8%, 13.9% and 6.5%, respectively. Over time, the cumulative risk of commencing corticosteroids decreased, whereas that of commencing thiopurines and anti-TNF agents increased. During follow-up, 28.7% of 778 patients with proctitis or left-sided colitis at diagnosis experienced proximal disease extension. A total of 28 patients (2.8%) underwent colectomy, demonstrating cumulative risks of colectomy at 1, 5, 10, 20 and 30 years after diagnosis of 1.0%, 1.9%, 2.2%, 5.1% and 6.4%, respectively. Multivariate Cox regression analysis revealed that extensive colitis at diagnosis (HR 8.249, 95% CI 2.394 to 28.430), ever use of corticosteroids (HR 6.437, 95% CI 1.440 to 28.773) and diagnosis in the anti-TNF era (HR 0.224, 95% CI 0.057 to 0.886) were independent predictors of colectomy. The standardised mortality ratio in patients with UC was 0.725 (95% CI 0.508 to 1.004). CONCLUSION Korean patients with UC may have a better clinical course than Western patients, as indicated by a lower colectomy rate. The overall colectomy rate has continued to decrease over the past three decades.

Concordance regarding disease type and phenotypic characteristics among patients with familial inflammatory bowel disease. J Gastroenterol Hepatol 2020; 35:988-993. [PMID: 31674059 DOI: 10.1111/jgh.14913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 10/03/2019] [Accepted: 10/13/2019] [Indexed: 12/09/2022]
Abstract
BACKGROUND AND AIMS The phenotypic concordance among familial cases of inflammatory bowel disease (IBD) has been rarely reported. Thus, the present study aimed to evaluate the concordance regarding disease type and phenotypic features in a large cohort of Korean patients with IBD. METHODS A total of 6647 patients with IBD who visited the Asan Medical Center between June 1989 and September 2016 were enrolled in the study. When at least two familial cases existed in our cohort, they were included in the concordance analysis (κ index). The concordance between younger and older members for IBD type [Crohn's disease (CD) and ulcerative colitis (UC)] and phenotypic characteristics such as disease extent and location, disease behavior, the use of medication, and need for surgery were evaluated. RESULTS A positive family history of IBD was noted in 216 patients with CD (7.0%) and in 238 patients with UC (6.7%). Of all patients, 167 consanguineous pairs in 146 families were identified. The crude concordance rate for IBD type was 82.6% with a κ index of 0.656 [95% confidence interval (CI): 0.545-0.768, good concordance]. There was mild concordance for disease location in CD (κ = 0.256; 95% CI: 0.007-0.505) and for the use of antitumor necrosis factor agents in UC (κ = 0.354; 95% CI: -0.049-0.757). The concordance for IBD type and several phenotypes in first-degree relative pairs was better than that in the entire pairs. CONCLUSIONS Disease type and phenotypic characteristics of patients with familial IBD may be anticipated.

Long-term Outcomes of Adalimumab Therapy in Korean Patients with Ulcerative Colitis: A Hospital-Based Cohort Study. Gut Liver 2020; 14:347-356. [PMID: 31530738 PMCID: PMC7234882 DOI: 10.5009/gnl19137] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 06/08/2019] [Accepted: 06/20/2019] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND/AIMS Studies on long-term outcomes of adalimumab therapy in non-Caucasian patients with ulcerative colitis (UC) are lacking. METHODS We analyzed long-term outcomes of Korean UC patients treated with adalimumab at the Asan Medical Center, Seoul, Korea. RESULTS Between July 2013 and October 2018, adalimumab therapy was started in a total of 100 patients with UC (65 males [65.0%]; median age, 39.5 years [interquartile range, 23.3 to 49.8 years]; and median disease duration, 3.0 years [interquartile range, 1.0 to 7.0 years]). The median duration of adalimumab therapy was 13.5 months (interquartile range, 4.0 to 32.0 months). Eight of 100 patients (8.0%) received induction therapy only, four (4.0%) of whom ultimately underwent colectomy. Of 92 patients who received adalimumab maintenance therapy, 30 (30.0%) stopped adalimumab therapy due to loss of response, and one patient (1.0%) was lost to follow-up. Among the 92 patients who received adalimumab maintenance therapy, the cumulative proportions of patients remaining on adalimumab maintenance therapy were 70.0% at 1 year and 48.9% at 5 years. High partial Mayo score after 8 weeks of adalimumab therapy (hazard ratio [HR], 1.217; 95% confidence interval [CI], 1.040 to 1.425; p=0.014) and a history of exposure to two biologic agents before adalimumab therapy (HR, 4.722; CI, 1.033 to 21.586; p=0.045) were predictors of adalimumab discontinuation. CONCLUSIONS Long-term outcomes of adalimumab therapy in Korean UC patients appear to be comparable to those in previously published Western studies. Furthermore, previous exposure to multiple biologic agents before adalimumab therapy and disease activity after 8 weeks of adalimumab therapy were predictors of adalimumab discontinuation.

Changes in prevalence and perception of complementary and alternative medicine use in Korean inflammatory bowel disease patients: results of an 8-year follow-up survey. Intest Res 2020; 18:192-199. [PMID: 32238788 PMCID: PMC7206343 DOI: 10.5217/ir.2019.00115] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Accepted: 01/11/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND/AIMS The use of complementary and alternative medicine (CAM) is a global phenomenon, including inflammatory bowel disease (IBD) patients. We aimed to assess the change in prevalence and patterns of CAM use, and attitudes towards CAM over an 8-year time interval (2006 vs. 2014) among IBD patients in Korea. METHODS A total of 221 IBD patients (CD=142, UC=79) were asked to complete a questionnaire regarding CAM at two time points: at enrollment (2006) and 8 years later (2014/2015). RESULTS The proportion of patients ever using CAM increased significantly from 60.2% in 2006 to 79.6% in 2014 (P<0.001), while the proportion of current CAM users increased slightly (35.7% to 38.0%, P=0.635); 21.7% used CAM consistently at both time points. The proportion of patients who felt CAM was less effective (P<0.001) and more expensive (P=0.04) than conventional treatments increased over time. Also, the proportion among ever CAM users who perceived a positive effect from CAM significantly decreased in 2014 compared to 2006 (P=0.004). Higher education (adjusted odds ratio [aOR], 2.10), prior side effects to conventional therapies (aOR, 2.23), and prior use of corticosteroids (aOR, 2.51) were associated with CAM use. Interestingly, use of CAM before IBD diagnosis (aOR, 2.73) was significantly associated with consistent CAM use. CONCLUSIONS Although the attitudes toward CAM have become less favorable, the majority of IBD patients have experienced CAM with an overall increase of current CAM users over time. Moreover, more than half of current CAM users used CAM consistently over time.

Incidence and risk factors of Pneumocystis jirovecii pneumonia in Korean patients with inflammatory bowel disease. J Gastroenterol Hepatol 2020; 35:218-224.

Abstract
BACKGROUND AND AIM Little is known whether routine prophylaxis against Pneumocystis jirovecii pneumonia (PJP) is needed in patients with inflammatory bowel disease (IBD) on immunosuppression, especially in Asian populations. We, therefore, sought to investigate the incidence and risk factors of PJP in patients with IBD in Korea. METHODS We investigated the incidence of PJP in patients with IBD and compared the characteristics of IBD patients with PJP episodes (IBD-PJP group) with those of matched controls (IBD-only group) using a large, well-characterized referral center-based cohort. RESULTS Among the 6803 IBD patients (3171 with Crohn's disease and 3632 with ulcerative colitis) enrolled in the Asan IBD Registry between June 1989 and December 2016, six patients (0.09%) were diagnosed with PJP. During the 57 776.0 patient-years of follow-up (median 7.2 years per patient), the incidence of PJP was 10.4 cases per 100 000 person-years, and none of these patients had received PJP prophylaxis. In case-control analysis, the IBD-PJP group (n = 6) showed significantly higher C-reactive protein level at diagnosis of IBD (P = 0.006), as well as higher exposure to corticosteroids (P = 0.017), than did controls (n = 24). In addition, the IBD-PJP group showed higher rates of double (50% vs 12.5%) or triple (33.3% vs 4.2%) immunosuppression than did controls, although these are not statistically significant. CONCLUSIONS Although the incidence of PJP in Korean patients with IBD is low, careful monitoring is necessary for the early detection of PJP. In addition to the patients receiving double or triple immunosuppression, PJP prophylaxis should be considered especially in patients with severe disease activities requiring corticosteroids.

Abstract
The inflammatory bowel diseases (IBD), which consist of Crohn's disease and ulcerative colitis, are chronic, incurable immunemediated inflammatory disorders of the intestine. As IBD incidence continues to increase globally and its mortality is low, prevalent cases of IBD are rapidly increasing, thereby leading to a substantial increase in health care costs. Although the introduction of biologic agents for IBD management has revolutionized the armamentarium of IBD therapy, the high cost of this therapy is concerning. With the expirations of patents for existing biologic agents (originals), biosimilars with cheaper costs have been highlighted in the field of IBD. Despite concerns regarding their short- and long-term efficacy, safety, immunogenicity, and interchangeability, increasing evidence via prospective observations and phase III or IV clinical trials, which aim to prove the "biosimilarity" of biosimilars to originals, has partly confirmed their efficacy, safety, and interchangeability. Additionally, although patients and physicians are reluctant to use biosimilars, a positive budget impact has been reported owing to their use in different countries. In the near future, multiple biosimilars with lower costs, and efficacy and safety profile similar to originals, could be used to treat IBD; thus, further consideration and knowledge dissemination are warranted in this new era of biosimilars.

Abstract
Introduction: Long-term, sustained, remission is the ultimate goal of contemporary inflammatory bowel disease (IBD) therapy. Avoiding complications, surgery and malignancy, alongside minimizing the side effects of medications are vital. However, the reality of treatment involves patients losing response to therapy, or developing complications requiring cessation of medication. The reasons underlying this are numerous and include medication and host-related influences. Underpinning the response to medication, long-term outcomes and loss of response are individual etiological factors including the molecular cause of disease and individual pharmacogenomic influences.Areas covered: In this review, we discuss the long-term outcome of IBD, with a focus on pediatric-onset illness and discuss the factors leading to loss of treatment response whilst briefly considering the future of personalized therapy as a strategy to improve long-term outcomes.Expert opinion: Research findings are now moving toward clinical translation, including application of novel medications targeting new pathways. The integration of biological and multiomic data to predict disease outcome will provide personalized therapeutic management.

Abstract
BACKGROUND AND AIM Tobacco smoking is a risk factor for gastrointestinal disorders, causing mucosal damage and impairing immune responses. However, smoking has been found to be protective against ulcerative colitis (UC). Human leukocyte antigen (HLA) is a major susceptibility locus for UC, and HLA-DRB1*15:02 has the strongest effect in Asians. This study investigated the effects of smoking on the association between HLA and UC. METHODS The study enrolled 882 patients with UC, including 526 never, 151 current, and 205 former smokers, and 3091 healthy controls, including 2124 never, 502 current, and 465 former smokers. Smoking-stratified analyses of HLA data were performed using a case-control approach. RESULTS In a case-control approach, HLA-DRB1*15:02 was associated with UC in never smokers (ORnever smokers = 3.20, Pnever smokers = 7.88 × 10-23 ) but not in current or former smokers (Pcurrent smokers = 0.72 and Pformer smokers = 0.33, respectively). In current smokers, HLA-DQB1*06 was associated with UC (ORcurrent smokers = 2.59, Pcurrent smokers = 6.39 × 10-12 ). No variants reached genome-wide significance in former smokers. CONCLUSIONS An association between UC and HLA-DRB1*15:02 was limited to never smokers. Our findings highlight that tobacco smoking modifies the effects of HLA on the risk of UC.

[PMID: 31312216 PMCID: PMC6595318 DOI: 10.1155/2019/4175923] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 05/05/2019] [Accepted: 05/15/2019] [Indexed: 02/07/2023] Open
Abstract
The incidence and prevalence of inflammatory bowel disease (IBD) are low but increasing in Taiwan. We aimed to investigate the epidemiology and clinical outcomes of IBD in central Taiwan. We retrospectively analyzed patients with IBD diagnosed at our hospital between January 2000 and September 2018. The diagnostic criteria were based on endoscopic and pathologic findings. Clinical characteristics, treatment regimens, and treatment outcomes were analyzed. A total of 190 patients with IBD were enrolled (80 with Crohn's disease (CD) and 110 with ulcerative colitis (UC)). The mean age at diagnosis was 38.4 years (CD: 36 years, UC: 40 years). Male patients accounted for the majority of patients (71.1%). The male-to-female ratio was 3 : 1 for CD and 2.1 : 1 for UC. Current and ever smokers accounted for 30.5% of all patients. Only 4.2% of patients had a family history of IBD. Extraintestinal manifestations (EIMs) were reported in 7.9%, and colorectal cancers (CRCs) were reported in 2.1% of all patients. In patients with CD, the ileal type was the most common disease phenotype (57.5%), and the stricturing type was the most common disease behavior (60.0%). In patients with UC, left-sided colitis was the predominant disease extent (42.7%). The seroprevalence of hepatitis B virus (HBV) was 13.3%. The incidence of perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) in patients with UC was 22%. 5-Aminosalicylic acids were the preferred treatment for UC, whereas corticosteroids, immunomodulators, and biologic agents were preferred for CD. In patients with CD, the bowel resection rate was 38.8%, and the incidence of hip avascular necrosis was 3.8%. In Taiwan, patients with IBD showed a male predominance, lack of familial clustering, a higher prevalence of HBV infection, and a lower prevalence of p-ANCA, EIMs, and CRC. Moreover, a higher incidence of the ileal type with poor outcomes of CD and left-sided predominance in UC were found.

Abstract
Inflammatory bowel diseases, which include Crohn's disease and ulcerative colitis, are lifetime chronic and progressive disorders of poorly known etiology. Over the past few decades, new therapeutic approaches, including early and more aggressive intervention with immunomodulators and biological agents have offered the possibility of a favorable modification in the natural history of inflammatory bowel diseases. Area covered: Here, we review the literature about the effectiveness of early detection and intervention in adult inflammatory bowel diseases patients. Expert commentary: Detecting and managing early stages of inflammatory bowel diseases represents an effective strategy to avoid disease progression in selected patients. Primary care physicians may play a key role in attaining these outcomes by recognizing the signs and symptoms early and making timely referrals. Moreover, early therapeutic intervention with complete disease control may allow dose reduction or even treatment withdrawal in the maintenance phase, reducing side effects, costs, and also improving quality of life.

Incidence and clinical impact of perianal disease in patients with ulcerative colitis: A nationwide population-based study. J Gastroenterol Hepatol 2019; 34:1011-1017. [PMID: 30549125 DOI: 10.1111/jgh.14555] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2018] [Revised: 11/14/2018] [Accepted: 11/14/2018] [Indexed: 12/30/2022]
Abstract
BACKGROUND AND AIM The risk and clinical impact of perianal disease (PAD) in ulcerative colitis (UC) patients have not been fully evaluated. We investigated the incidence of PAD in UC patients and compared clinical characteristics and outcomes of UC according to the presence of PAD. METHODS We performed a nationwide population-based cohort study and a hospital-based cohort study. Using the 2010-2014 data from the Korean National Health Insurance claims database, we calculated incidence rates and standardized incidence ratios of PAD in UC patients compared with the general population. We evaluated the clinical characteristics and outcomes of UC patients with PAD in both population-based and hospital-based cohorts. To reduce clinically meaningful confounding factors, we also conducted matched analyses. RESULTS In the population-based cohort, the incidence rate and standardized incidence ratio of PAD in UC patients were 3.74/1000 person-years (95% confidence interval, 3.25-4.31) and 2.88 (95% confidence interval, 2.50-3.32), respectively. In the hospital-based cohort, the cumulative probabilities of PAD at 1, 5, 10, and 20 years after diagnosis were 1.0%, 2.3%, 4.0%, and 6.3%, respectively. In both population-based and hospital-based cohorts, UC patients with PAD showed higher proportions of corticosteroid use and extensive colitis at diagnosis. The requirements for anti-tumor necrosis factor agents and colectomy were significantly higher in UC patients with PAD before and after matched analysis. CONCLUSIONS The risk of PAD is higher in UC patients than in the general population. UC patients with PAD have distinct clinical features and poor outcomes, as indicated by the greater need for UC-related medications and colectomy.

Abstract
BACKGROUND Ulcerative colitis (UC) is an uncommon inflammatory bowel disease (IBD). However, its incidence has recently increased in South Korea. Moreover, UC diagnoses are frequently delayed, and the relationship between diagnostic delay and UC prognosis has not been extensively studied in South Korean patients.
AIM To identify meaningful diagnostic delay affecting UC prognosis and to evaluate risk factors associated with diagnostic delay in South Korean patients.
METHODS Medical records of 718 patients with UC who visited the outpatient clinic of six university hospitals in South Korea were reviewed; 167 cases were excluded because the first symptom date was unknown. We evaluated the relationship between the prognosis and a diagnostic delay of 3, 6, 12, 18, and 24 mo by comparing the prognostic factors [anti-tumor necrosis factor (TNF)-α use, admission history due to acute flare-ups, frequent admission due to flare-ups, surgery associated with UC, and the clinical remission state at the latest follow-up] at each diagnostic interval.
RESULTS The mean diagnostic interval was 223.3 ± 483.2 d (median, 69 d; 75th percentile, 195 d). Among the prognostic factors, anti-TNFα use was significantly increased after a diagnostic delay of 24 mo. Clinical risk factors predictive of a 24-mo diagnostic delay were age < 60 years at diagnosis [odd ratio (OR) = 14.778, 95% confidence interval (CI): 1.731-126.121], smoking history (OR = 2.688, 95%CI: 1.239-5.747, P = 0.012), and misdiagnosis of hemorrhoids (OR = 11.066, 95%CI: 3.596-34.053). Anti-TNFα use was associated with extensive UC at diagnosis (OR = 3.768, 95%CI: 1.860-7.632) and 24-mo diagnostic delay (OR = 2.599, 95%CI: 1.006-4.916).
CONCLUSION A diagnostic delay > 24 mo was associated with increased anti-TNFα use. Age < 60 years at diagnosis, smoking history, and misdiagnosis of hemorrhoids were risk factors for delayed diagnosis.

Risk factors and long-term outcome of disease extent progression in Asian patients with ulcerative colitis: a retrospective cohort study. BMC Gastroenterol 2019; 19:7. [PMID: 30630426 PMCID: PMC6327558 DOI: 10.1186/s12876-018-0928-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Accepted: 12/27/2018] [Indexed: 02/07/2023] Open
Abstract
Background The incidence of Ulcerative colitis (UC) in Asia is increasing but reports on its long-term course are few. The aim of this study was to identify risk factors predictive of extent progression in Asian patients with UC and to evaluate the clinical outcome by longitudinal follow-up. Methods We retrospectively analyzed 518 UC patients without ascending colon involvement at diagnosis who were regularly followed and underwent colonoscopy between 2003 and 2016 in an Asian tertiary referral center. Proximal disease extension and associated risk factors were analyzed. Results A total of 91 (17.6%) patients experienced proximal disease extension followed for a median period of 7.5 years. The median time for extent extension was 16.1 months (interquartile range (IQR) 8.3–42.2). The cumulative rate of disease extension was 9.9, 14.9, 19.6, 24.6 and 30.5% at 1,2,3,4 and 5 years after diagnosis. 43 (12.0%) patients with E1/E2 progressed to E3, and 40 (21.9%) with E1 progressed to E2. Of patients diagnosed with E3 involvement limited to the hepatic flexure distally, 8 (13.3%) progressed to pancolitis. Cox regression analysis found that disease extent at diagnosis was the sole predictor of disease extension (odds ratio (OR),1.74, 95% confidence interval (CI) 1.18–2.57, p = 0.01). Proximal disease extension was associated with disease relapse (p = 0.03) and increased use of steroids and immunosuppressive agents (p < 0.01). Conclusion UC is a dynamic disease and that the disease extension in Asians was comparable to that in Caucasians. Proximal disease extension increased the risk of disease flare and treatment intensification.

Abstract
BACKGROUND & AIMS Few data are available on risk of herpes zoster (HZ) infection in Asian patients with inflammatory bowel diseases (IBD). We investigated whether patients with IBD in Korea have an increased risk of HZ and sought to identify risk factors for infection. METHODS We performed a nationwide population-based study and a hospital-based, nested case-control study. Using the 2009-2013 data from the Korean national health insurance claims database, we calculated incidence rates and standardized incidence ratios (SIRs) of HZ infection in patients with IBD compared with the entire Korean population. In the nested case-control study, within a hospital-based cohort, 300 patients with IBD and HZ infection were matched with 895 patients with IBD without HZ. RESULTS In the nationwide population-based study, the incidence rate and SIR of HZ infection in patients with IBD were 18.34/1000 person-years and 1.48 (95% CI, 1.42-1.54), respectively. The SIR for HZ infection was higher in patients with Crohn's disease than in patients with ulcerative colitis (1.90 vs 1.36; P < .001) and higher in male patients than female patients (1.63 vs 1.33; P < .001). The incidence rate of HZ increased with age (P trend < .001), whereas the SIR of HZ infection decreased with age (P trend < .001). In the nested case-control study, corticosteroid use was associated with HZ infection (for ulcerative colitis, adjusted odds ratio, 2.44; 95% CI, 1.18-5.05 and for Crohn's disease, adjusted odds ratio, 2.70; 95% CI 1.25-5.83). CONCLUSIONS In a population-based study in Korea, we found patients with IBD to have an increased risk for HZ infection-especially among patients who are male, younger, or have Crohn's disease. Corticosteroid use increases risk of HZ infection in patients with IBD.

Abstract
BACKGROUND AND AIMS The genetic contribution to the prognosis of ulcerative colitis [UC] is poorly understood, and most currently known susceptibility loci are not associated with prognosis. To identify genetic variants influencing the prognosis of UC, we performed an Immunochip-based study using an extreme phenotype approach. METHODS Based on the finding that the only association, Pdiscovery-meta <1 × 10-4, was located in the human leukocyte antigen [HLA], we focused our analyses on the HLA region. We performed the analysis using HLA imputation data from three independent discovery cohorts of 607 UC patients [243 poor-prognosis and 364 good-prognosis], followed by replication in 274 UC patients [145 poor-prognosis and 129 good-prognosis]. RESULTS We found that rs9268877, located between HLA-DRA and HLA-DRB, was associated with poor-prognosis of UC at genome-wide significance (odds ratio [ORdiscovery] = 1.82; ORreplication = 1.55; ORcombined-meta = 1.72, pcombined-meta = 1.04 × 10-8), with effect size [OR] increasing incrementally according to worsening of prognosis in each of the three independent discovery cohorts and the replication cohort. However, rs9268877 showed no association with UC susceptibility [ORcombined-meta = 1.07, pcombined-meta = 0.135]; rs9268877 influenced 30-year clinical outcomes, and the presence of the rs9268877 risk allele had a sensitivity of 80.0% and specificity of 38.1% for colectomy. CONCLUSIONS Our results provide new insights into prognosis-associated genetic variation in UC, which appears to be distinct from the genetic contribution to disease susceptibility. These findings could be useful in identifying poor-prognosis patients who might benefit from early aggressive therapy.

Abstract
Ulcerative colitis (UC) is a chronic, relapsing, remitting, and inflammatory disorder that afflicts millions of people around the world. It carries a substantial economic burden, reducing the quality of life, ability to work, and increasing disability. Conventional medical treatment of UC includes the use of aminosalicylates, corticosteroids, and immunosuppressive drugs. However, these medicines are not always effective due to some serious side effects. Nuclear factor-kappa B (NF-κB) is a key factor in the inflammatory setting and strongly affects the course of mucosal inflammation in UC. This review aims to describe the complex role of NF-κB in UC and discuss existing pharmacological attempts by curcumin for blocking NF-κB activation to develop new therapeutic strategies in UC. Several studies have shown intriguing pharmacologic effects associated with curcumin, which inhibits NF-κB expression by regulating NF-κB/IkB pathway and down-regulation expression of pro-inflammatory cytokines, such as Interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor (TNF)-α. The efficacy of curcumin has been confirmed in several experimental models of UC. Furthermore, curcumin significantly induced clinical remission in active mild-to-moderate UC patients and reduced clinical relapse in quiescent UC patients. The inhibitory effects of curcumin on NF-κB and its unrivaled safety profile indicate that it remains effective for the treatment of UC. In addition, curcumin is a nontoxic, inexpensive, and easily available natural polyphenol. In conclusion, curcumin can be used as a potential and safe drug in the management of patients with remission and mild-to-moderate UC.

Abstract
Owing to the recent progress in regenerative medicine technology, clinical trials that harnessed the regeneration and immune modulation potentiality of stem cells for treating IBD have shown promising results. We investigated the feasibility and utility of intraluminal endoscopic transplantation of rat MSC sheets in murine models of experimental colitis for targeted delivery of stem cells to lesions. We isolated adipose-derived mesenchymal stem cells (AD-MSC) and bone marrow-derived mesenchymal stem cells (BM-MSC) from EGFP-transgenic rats and fabricated the cells in sheet forms using temperature-responsive culture dishes. The MSC sheets were endoscopically transplanted to the inflamed area in electrocoagulation and DNBS colitis model. The effect of the transplantation was verified using endoscopic scoring and histological analysis. In the electrocoagulation model, the AD-MSC group showed significantly decreased ulcer size in the transplanted regions. In the DNBS colitis model, the AD-MSC group showed decreased inflammation and colitis in the transplanted regions. Histologic analysis showed that the MSC sheets had successfully attached to the inflamed mucosa in both the electrocoagulation and DNBS colitis model. Our results show that endoscopic transplantation of MSC sheets could be a new effective mode of stem cell therapy for IBD treatment.

[PMID: 29063720 DOI: 10.1111/jgh.14031] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Revised: 10/13/2017] [Accepted: 10/16/2017] [Indexed: 12/19/2022]
Abstract
BACKGROUND AND AIM CDKN2A/CDKN2B locus on 9p21 is reported to be associated with various diseases, including cancer and cardiovascular and inflammatory diseases. Significant downregulation of CDKN2B-AS1 in inflamed colon tissue of inflammatory bowel disease (IBD) cases was reported in Europeans. This study aimed to confirm the suggestive association of CDKN2A/CDKN2B with IBD identified in our recent genome-wide association study (GWAS). METHODS We examined the association of CDKN2A/CDKN2B locus with IBD in an additional sample of 574 IBD cases and 542 controls, totaling 4068 cases and 8074 controls. In silico study was performed at various levels for functional annotation of the causal variant. Co-localization of the GWAS association signals and the corresponding expression quantitative trait loci in IBD-related tissues was evaluated using eCAVIAR. RESULTS An expanded GWAS showed genome-wide significant association of rs3731257 at 9p21 with IBD (odds ratio = 1.17, 95% confidence interval = 1.12-1.22, Pcombined = 5.68 × 10-9 ) and Crohn's disease (odds ratio = 1.22, 95% confidence interval = 1.15-1.28, Pcombined = 8.85 × 10-9 ) in the Korean population. Co-localization study suggested that both CDKN2B-AS1 and CDKN2A might be functionally associated with the locus in the small intestine. CONCLUSIONS rs3731257 in CDKN2A/CDKN2B is an IBD-susceptible locus in Koreans, with a suggestive role for small intestine-specific gene regulation. Our findings suggested that alterations of the CDKN2A/CDKN2B locus could affect the pathophysiology of IBD.

Abstract
Recently, the incidence and prevalence of inflammatory bowel disease (IBD) have been increasing in worldwide, especially in Asian area. IBD is a chronic and progressive disease eventually causing bowel damage. The advance in the treatment of IBD over the past several decades has been achieved with the development of biologics. Furthermore, goals for management of IBD have been evolving from symptom-based management to mucosal healing, which can reduce the surgery rate and hospitalization. To treat the patients with IBD properly, identification of risk factors of patients should be preceded. In addition, the knowledge of several drugs, which are available in current situation is essential. In this review, optimal therapeutic approach with drugs including 5-aminosalicylate, steroid, immunomodulators and anti-TNF antagonists is discussed.

Abstract
To clarify the different effects of live and heat-killed probiotics on inflammatory bowel disease (IBD), the anti-inflammatory and protective effects of Lactobacillus plantarum AN1 cells isolated from the fermented fish aji-narezushi on murine macrophage RAW264.7 cells and in ICR mice with dextran sodium sulphate (DSS)-induced IBD were determined. L. plantarum AN1 cells showed anti-inflammatory activities in vitro, indicated by secretion of nitric oxide (NO) from RAW264.7 cells in the presence and absence of Escherichia coli 0111 lipopolysaccharide (LPS). L. plantarum AN1 cells also protected RAW264.7 cells against hydrogen peroxide toxicity. There was no difference between these effects in heat-killed and ultraviolet irradiation-killed cells. In the murine IBD model, both live and heat-killed L. plantarum AN1 cells via drinking water tended to ameliorate atrophy of colon length, mucosal tissue damage, and spleen enlargement. Amplicon sequencing of 16S rDNA (V4) revealed that both live and heat-killed AN1 cells increased abundance of indigenous lactic acid bacteria, particularly Lactobacillus reuteri. The results suggest that increased indigenous lactic acid bacterial abundance and feeding with L. plantarum AN1 cells synergistically improve effects against IBD.

Abstract
Inflammatory bowel disease (IBD) is a chronic and progressive inf lammatory condition of the gastrointestinal tract causing bowel damage, hospitalizations, surgeries, and disability. Although there has been much progress in the management of IBD with established and evolving therapies, most current approaches have failed to change the natural course. Therefore, the treatment approach and follow-up of patients with IBD have undergone a significant change. Usage of immunosuppressants and/or biologics early during the course of the disease, known as top-down or accelerated step-up approach, was shown to be superior to conventional management in patients who had been recently diagnosed with IBD. This approach can be applied to selected groups based on prognostic factors to control disease activity and prevent progressive disease. Therapeutic targets have been shifted from clinical remission mainly based on symptoms to objective parameters such as endoscopic healing due to the discrepancies observed between symptoms, objectively evaluated inf lammatory activity, and intestinal damage. The concept of treat-to-target in IBD has been supported by population-based cohort studies, post hoc analysis of clinical trials, and meta-analysis, but more evidence is needed to support this concept to be applied to the clinical practice. In addition, individualized approach with tight monitoring of non-invasive biomarker such as C-reactive protein and fecal calprotectin and drug concentration has shown to improve clinical and endoscopic outcomes. An appropriate de-escalation strategy is considered based on patient demographics, disease features, current disease status, and patients' preferences.

Abstract
BACKGROUND AND AIM Smoking cessation is known to improve the course of Crohn's disease (CD). However, the factors associated with smoking cessation after CD diagnosis have not been well established. METHODS Clinical characteristics and change in smoking status were evaluated in 445 current smokers at the time of CD diagnosis. Patients were classified into three subgroups based on their final smoking status and time of smoking cessation: non-quitters, quitters at diagnosis, and quitters during follow-up. RESULTS The overall smoking cessation rate was 55.7% (248 of 445 patients). The diagnosis of CD was the main reason for quitting (41.5%, 103 of 248 patients). Smoking cessation at the time of CD diagnosis was associated with intestinal resection within 3 months from CD diagnosis (odds ratio [OR] 2.355, 95% confidence interval [CI] 1.348-4.116, P = 0.003), light smoking (OR 2.041, 95% CI 1.157-3.602, P = 0.014), and initiation of smoking before 18 years of age (OR 0.570, 95% CI 0.327-0.994, P = 0.047). Light smoking (OR 1.762, 95% CI 1.019-3.144, P = 0.043) and initiation of smoking before 18 years (OR 0.588, 95% CI 0.381-0.908, P = 0.017) were also associated with overall smoking cessation. CONCLUSION Quitters after CD diagnosis, including quitters at diagnosis and quitters during follow-up, had features distinct from those of non-quitters. Given the motivation at CD diagnosis, a detailed history of smoking habits should be taken and all current smokers should be encouraged to quit smoking at the time of CD diagnosis.

Abstract
BACKGROUND AND AIM The aim of this study was to investigate the clinical characteristics and prognosis of patients with elderly onset ulcerative colitis (EOUC), a new growing subgroup of UC. METHODS This study retrospectively analyzed 3060 South Korean UC patients diagnosed between 1977 and 2014. The clinical characteristics and prognosis of EOUC, defined as UC in those aged ≥ 60 years at diagnosis, were compared with those of non-EOUC (NEOUC). RESULTS Among the 3060 patients, 226 were diagnosed with EOUC (7.4%, median age at diagnosis 65.9 years [interquartile range, 62.9-68.7 years], 58.4% male). The frequency of EOUC increased from 3.9% in the interval 1977-1999 to 9.7% in the interval 2008-2014 (P < 0.001). There were more ex-smokers in the EOUC than in the NEOUC group (44.2% vs 19.9%, P < 0.001). In the EOUC group, extensive colitis at diagnosis, and the maximum extent thereof, was less than in the NEOUC group (13.7% vs 22.6%, P = 0.002, and 34.5% vs 42.5%, P = 0.011, respectively). The 10-year cumulative colectomy rate was significantly higher in the EOUC than in the NEOUC group (12.6% vs 7.7%, P = 0.015). UC-related and all-cause mortality were higher in the EOUC than in the NEOUC group (3.5% vs 0.6%, P < 0.001, and 12.4% vs 1.8%, P < 0.001, respectively). CONCLUSION Elderly onset ulcerative colitis patients are likely to exhibit distinct features both at diagnosis and during follow-up. It is necessary to pay more attention to, and to conduct further studies on, this particular group of patients.

Abstract
Children and young adults with ulcerative colitis tend to present with more extensive colonic disease than an adult population. The need for surgical intervention in the pediatric population with ulcerative colitis occurs earlier after diagnosis and has a greater incidence than a comparably matched adult population with an estimated need for colectomy at 5 years following diagnosis of 14-20%. Perhaps, even more than the adult population, there is a desire to restore intestinal continuity for the pediatric patient to achieve as healthy and normal quality of life as possible. With surgery playing such a prominent role in the treatment of ulcerative colitis in this age group, an understanding of the surgical treatment options that are available is important. The surgeon's awareness of the complexities of the different operations associated with proctocolectomy and reestablishing intestinal continuity may help to avoid early complications and minimize the risk of less than ideal long-term outcomes.

Fecal calprotectin predicts complete mucosal healing and better correlates with the ulcerative colitis endoscopic index of severity than with the Mayo endoscopic subscore in patients with ulcerative colitis. BMC Gastroenterol 2017; 17:110. [PMID: 29061121 PMCID: PMC5654142 DOI: 10.1186/s12876-017-0669-7] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Accepted: 10/15/2017] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND We aimed to evaluate the role of fecal calprotectin (FC) as a noninvasive marker for the disease activity of ulcerative colitis (UC) in a Korean cohort. METHODS A total of 181 fecal samples were collected from 181 consecutive UC patients between April 2015 and September 2016. FC levels were measured using the Quantum Blue® Calprotectin rapid test. The laboratory test results, partial Mayo Score (pMS), and colonoscopic imaging findings at FC level measurement were retrospectively reviewed. The Mayo endoscopic subscore (MES) and UC endoscopic index of severity (UCEIS) were graded by 2 certified endoscopists after training with 50 other cases. RESULTS The FC levels were significantly correlated with pMS (Spearman correlation coefficient r = 0.428, p < 0.001), MES (r = 0.304, p < 0.001), UCEIS (r = 0.430, p < 0.001), and CRP (r = 0.379, p < 0.001). FC levels exhibited a significantly better correlation with UCEIS than with MES (Meng's z = - 2.457, p = 0.01). The FC cut-off level of 187.0 mg/kg indicated complete mucosal healing (MES = 0; UCEIS =0) with a sensitivity and specificity of 0.857 and 0.891, respectively (area under the curve, 0.883; 95% confidence interval, 0.772-1.000). CONCLUSION The FC level is significantly correlated with the clinical disease activity index, endoscopic indices, and serum inflammatory biomarkers in a Korean UC cohort. FC is highly predictive of complete mucosal healing in UC. UCEIS exhibits a stronger correlation with the FC level, as compared to MES. Thus, FC could be used as a reliable noninvasive indicator for evaluating disease activity and mucosal healing in UC.

Long-Term Outcomes of Adalimumab Treatment in 254 Patients with Crohn's Disease: A Hospital-Based Cohort Study from Korea. Dig Dis Sci 2017; 62:2882-2893. [PMID: 28822006 DOI: 10.1007/s10620-017-4715-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2017] [Accepted: 08/07/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Large-scale studies regarding the long-term outcomes of adalimumab (ADA) treatment in Asian patients with Crohn's disease (CD) are still scarce. METHODS We retrospectively analyzed the long-term outcomes of ADA treatment in Korean CD patients who commenced on scheduled ADA treatment at Asan Medical Center between November 2008 and July 2016. Clinical response was defined as maintaining ADA treatment without dose intensification (DI) and/or major abdominal surgery (MAS). RESULTS Of the 254 patients who received at least two doses of ADA at 2-week intervals as induction therapy, 250 patients (98.4%) showed an initial favorable response by week 4. Among responders, 243 patients were followed up for longer than 4 weeks and were included for further analysis. The median duration of ADA maintenance therapy was 19.4 months. At the last follow-up, 45 patients (18.5%) required DI after a median of 16.8 months and 31 (12.8%) required MAS after a median of 8.9 months. Finally, 161 patients (66.3%) were still receiving ADA without DI and/or MAS. The cumulative probability of maintaining ADA without DI and/or MAS was 81.1% at 1 year, and 36.5% at 5 years. Secondary loss of response to previous infliximab (P = 0.001) and elevated baseline C-reactive protein at starting ADA treatment (P = 0.008) were identified as independent predictors of a poor response to ADA treatment using multivariate regression analysis. CONCLUSIONS The long-term outcome of ADA treatment in a real-life cohort of Korean patients with CD appears to be comparable to that reported in previously published Western studies.

Abstract
AIM To investigate the changes of postoperative anal sphincter function and bowel frequency in Korean patients with ulcerative colitis (UC).
METHODS A total of 127 patients with UC who underwent restorative proctocolectomy (RPC) during 20 years were retrospectively analyzed. The parameters of anal manometry and bowel frequency were compared according to the 6-mo intervals until 24 mo postoperatively. Manometry was used to measure the maximal squeezing pressure (MSP) and maximal resting pressure (MRP).
RESULTS MSP decreased after surgery until 6 mo (157 to 142 mmHg); thereafter, it improved and was recovered to and maintained at the preoperative value at 12 mo postoperatively (142-170 mmHg, P < 0.001). Although the decreased MRP (65 to 56 mmHg) improved after 18 mo (62 mmHg), it did not completely recover to the preoperative value. The decreased rectal capacity after surgery (90 to 82 mL) gradually increased up to 150 mL at 24 mo. Although bowel frequency showed significant gradual decreases at each interval, it was stabilized after 12 mo postoperatively (6.5 times/d).
CONCLUSION Postoperative changes of manometry and bowel frequency after restorative proctocolectomy in Korean patients with UC were not different from those in Western patients with UC.

Abstract
BACKGROUND Large-scale studies regarding the long-term efficacy of infliximab (IFX) treatment in non-Caucasian patients with ulcerative colitis (UC) are lacking. STUDY We analyzed the long-term outcomes of IFX in 195 Korean UC patients who received scheduled IFX treatments at Asan Medical Center. IFX failure was defined as IFX discontinuation due to colectomy or non-response to IFX, and additionally UC-related hospitalization or a need for rescue corticosteroids during the course of IFX. RESULTS Between December 2006 and October 2016, a total of 3101 infusions of IFX were administered to 195 patients over a median period of 21 months. At the end of the follow-up, 86 patients (44.1%) were still receiving IFX without failure. IFX was stopped in 73 (37.4%) patients due to colectomy (23 patients, 11.8%), non-response to IFX (35 patients, 17.9%) or other reasons such as adverse events or patients' preferences (15 patients, 7.7%). An additional 36 (18.5%) patients experienced IFX failure during follow-up due to a need for rescue corticosteroids (13 patients, 6.7%), UC-related hospitalization (8 patients, 4.1%), or both (15 patients, 7.7%). The survival free of IFX failure was 58.1% at 1 year, 50.7% at 3 years and 44.8% at 5 years. In a multivariate regression analysis, cytomegalovirus colitis within 3 months before IFX initiation was a predictor of IFX failure (hazard ratio 1.57; 95% confidence interval 1.04-2.37; p = .032). CONCLUSIONS The long-term efficacy of IFX in a large, real-life cohort of Korean UC patients appears to be comparable to that in previously published Western studies.

Abstract
BACKGROUND The incidence of inflammatory bowel disease (IBD) is increasing in East Asia; however, population-based data from this region are lacking. AIM We conducted a nationwide, population-based study to examine the incidence and disease course of IBD in South Korea. METHODS Using the National Health Insurance claims data, we collected data on patients diagnosed with IBD [10,049 with ulcerative colitis (UC) and 5595 with Crohn's disease (CD)] from 2011 to 2014. RESULTS During the study period, the average annual incidence of UC was 5.0 per 105, while that of CD was 2.8 per 105. Among patients with UC, the cumulative rates of surgery 1 and 4 years after diagnosis were 1.0 and 2.0%; those among patients with CD were 9.0 and 13.9%, respectively. The 1- and 4-year cumulative rates of moderate- to high-dose corticosteroid use were, respectively, 26.6 and 45.2% among patients with UC, and 29.9 and 50.8% among those with CD. Similarly, the 1- and 4-year cumulative rates of immunomodulator use were 14.1 and 26.4% among patients with UC, and 58.3 and 76.1% among those with CD, respectively. With regard to biologic use, the 1- and 4-year cumulative rates were 3.0 and 9.0% among patients with UC, and 11.1 and 31.7% among those with CD, respectively. CONCLUSIONS The recent incidence of IBD in South Korea has been the highest in East Asia. Patients who had been diagnosed recently with IBD showed lower rates of surgery and higher rates of immunomodulator and biologic use compared to those reported ever in South Korea.

Abstract
BACKGROUND AND AIMS Genome-wide association studies of inflammatory bowel disease identified > 200 susceptibility loci only in autosomes. This study aimed to identify inflammatory bowel disease susceptibility loci on the X chromosome. METHODS We performed an X chromosome-wide association study in Korean patients with inflammatory bowel disease. We analysed X chromosome data from our recent genome-wide association studies, including 1505 cases [922 Crohn's disease and 583 ulcerative colitis] and 4041 controls during the discovery phase, followed by replication in additional 1989 cases [993 Crohn's disease, 996 ulcerative colitis] and 3491 controls. Sex-related differential effects of single nucleotide polymorphisms on disease were also evaluated. RESULTS We confirmed a significant association of a previously reported inflammatory bowel disease susceptibility locus at chromosome Xq26.3 [CD40LG-ARHGEF6; odds ratio, 1.22; 95% confidence interval, 1.16-1.28; combined p = 3.79 × 10-15]. This locus accounted for 0.18% and 0.12% of genetic variance in Crohn's disease and ulcerative colitis, respectively, and increased the total autosomal chromosome genetic variance from 6.65% to 6.83% and from 5.47% to 5.59% for Crohn's disease and ulcerative colitis risk, respectively, in the Korean population. Sex-stratified analyses did not reveal sex-related differences in effect sizes. CONCLUSIONS We confirmed the association of rs2427870 at the CD40LG-ARHGEF6 locus with an inflammatory bowel disease through an X chromosome-wide association study in a Korean population. Our data suggest that the CD40LG-ARHGEF6 locus on the X chromosome might play a role in inflammatory bowel disease pathogenesis in the Korean population.

Abstract
AIM To investigate the clinical course of ulcerative colitis (UC) patients who develop acute pancreatitis.
METHODS We analyzed 3307 UC patients from the inflammatory bowel disease registry at Asan Medical Center from June 1989 to May 2015. The clinical course of UC patients who developed acute pancreatitis was compared with that of non-pancreatitis UC patients.
RESULTS Among 51 patients who developed acute pancreatitis, 13 (0.40%) had autoimmune, 10 (0.30%) had aminosalicylate-induced, and 13 (1.73%) had thiopurine-induced pancreatitis. All 13 patients with autoimmune pancreatitis (AIP) had type 2 AIP. Two (15.4%) patients had pre-existing AIP, and three (23.1%) patients developed AIP and UC simultaneously. Compared to non-pancreatitis patients, AIP patients had UC diagnosed at a significantly younger age (median, 22.9 years vs 36.4 years; P = 0.001). AIP and aminosalicylate-induced pancreatitis patients had more extensive UC compared to non-pancreatitis patients. All patients with pancreatitis recovered uneventfully, and there were no recurrences. Biologics were used more frequently in aminosalicylate- and thiopurine-induced pancreatitis patients compared to non-pancreatitis patients [adjusted OR (95%CI), 5.16 (1.42-18.67) and 6.90 (1.83-25.98), respectively]. Biologic utilization rate was similar among AIP and non-pancreatitis patients [OR (95%CI), 0.84 (0.11-6.66)]. Colectomy rates for autoimmune, aminosalicylate-induced, and thiopurine-induced pancreatitis, and for non-pancreatitis patients were 15.4% (2/13), 20% (2/10), 15.4% (2/13), and 7.3% (239/3256), respectively; the rates were not significantly different after adjusting for baseline disease extent.
CONCLUSION Pancreatitis patients show a non-significant increase in colectomy, after adjusting for baseline disease extent.

Abstract
BACKGROUND AND AIM Limited data are available regarding mortality from inflammatory bowel disease in non-Caucasian populations. Herein, we evaluated overall and cause-specific mortality in a hospital-based cohort of Korean inflammatory bowel disease patients. METHODS We determined mortality in 2414 Crohn's disease patients and 2798 ulcerative colitis patients diagnosed between 1977 and 2013. Standardized mortality ratios were calculated in several demographic and phenotypic subgroups. RESULTS During the mean 9-year follow up, 114 patients died: 35 with Crohn's disease and 79 with ulcerative colitis. The overall standardized mortality ratios were 1.40 (95% confidence interval: 0.97-1.94) in Crohn's disease and 0.73 (0.58-0.91) in ulcerative colitis. In Crohn's disease, female sex, age < 30 years at diagnosis, disease duration > 10 years, ileocolonic disease at diagnosis, perianal fistula, intestinal resection, and ever-use of corticosteroids were associated with higher mortality. In ulcerative colitis, male sex, age ≥ 30 years at diagnosis, disease duration ≤ 5 years, proctitis at diagnosis, and no history of colectomy were associated with lower mortality, while primary sclerosing cholangitis was associated with higher mortality. In both Crohn's disease and ulcerative colitis, high mortality rates due to nonmalignant gastrointestinal causes (standardized mortality ratios: 4.59 and 2.32, respectively) and gastrointestinal malignancies (standardized mortality ratios: 16.59 and 3.45, respectively) were observed. Cardiovascular mortality was lower in ulcerative colitis (standardized mortality ratio: 0.47). CONCLUSIONS The overall mortality tended to be higher in Crohn's disease patients than in the general population; it was slightly lower in ulcerative colitis patients than in the general population.

Abstract
Background Though low compared with those in Western countries, the incidence and prevalence of inflammatory bowel disease (IBD) are rapidly increasing in Asia. If we could understand the differences in IBD epidemiology between Asian and Western countries, we might gain insights into the etiopathogenesis of IBD as well as guidance for personalized therapy. Summary In Asia, unlike in the West, Crohn's disease (CD) predominantly occurs in men and involves a high prevalence of perianal fistulas. Moreover, in Korean CD patients, ileocolonic involvement is predominant, whereas isolated colonic involvement is very uncommon. In both ulcerative colitis (UC) and CD, extraintestinal manifestations, such as primary sclerosing cholangitis, as well as a positive family history of IBD are less frequent in Asian patients. However, as the prevalence of IBD rises in Korea, so does the frequency of a positive family history. While the colectomy rate among Korean UC patients is lower, the intestinal resection rate in CD patients is similar in Korea and in the West. Infectious problems that can adversely influence IBD management are usually more common in Asia. Key Messages IBD in Asians differs from that in Westerners in many aspects, including demographic and clinical characteristics, prognosis, and associated problems.

Abstract
A substantial proportion of patients with ulcerative colitis (UC) have failed conventional therapies such as steroids, immunosuppressants or TNF-antibodies, or have experienced side effects. This article reviews the pharmacological properties of vedolizumab (VDZ), its efficacy and side effects in UC. By its relatively specific gut-selective mode of action, VDZ's safety profile appears more favorable than that of anti-TNF therapies. VDZ is more effective than placebo for the induction and maintenance of remission in moderate-to-severe UC in both naïve patients and patients who have failed anti-TNF treatment. However, in some patients, VDZ has a slower onset of action. But, to place VDZ as a first-line therapy, it must go head-to-head with azathioprine and anti-TNF antibodies in future studies.

Preoperative Anti-tumor Necrosis Factor Therapy in Patients with Ulcerative Colitis Is Not Associated with an Increased Risk of Infectious and Noninfectious Complications After Ileal Pouch-anal Anastomosis. Inflamm Bowel Dis 2016; 22:2442-7.

Abstract
BACKGROUND There are conflicting data regarding the effect of previous exposure to anti-tumor necrosis factor (anti-TNF) therapy on complication rates after pelvic pouch surgery for patients with ulcerative colitis (UC). In particular, there is concern surrounding the rates of pouch leaks and infectious complications, including pelvic abscesses, in anti-TNF-treated subjects who require ileal pouch-anal anastomosis (IPAA) surgery. METHODS A retrospective study was performed in UC subjects who underwent IPAA between 2002 and 2013. Demographic data, clinical data, use of anti-TNF therapy, steroids, immunosuppressants, and surgical outcomes were assessed. RESULTS Seven hundred seventy-three patients with UC/IPAA were reviewed. Fifteen patients were excluded from the analysis because of missing data. There were 196 patients who were exposed to anti-TNF therapy and 562 patients who were not exposed to anti-TNF therapy preoperatively. There were no significant differences in the postoperative IPAA leak rate between those exposed to anti-TNF therapy and the control group (n = 26 [13.2%] versus 66 [11.7%], respectively, P = 0.44). In addition, there were no significant differences in the postoperative 2-stage IPAA leak rate in those who had been operated on within 15 days from the last anti-TNF dose (n = 10), within 15 to 30 days (n = 17), or 31 to 180 days (n = 54) (10%, 5.9%, and 14.8% respectively, P = 0.43) nor were there differences based on the presence of detectable infliximab serum levels. CONCLUSIONS Preoperative anti-TNF therapy in patients with UC is not associated with an increased risk of infectious and noninfectious complications after IPAA including pelvic abscesses, leaks, and wound infections.
