Abstract
BACKGROUND Despite the rising prevalence of Inflammatory Bowel Disease (IBD), age and sex differences in its outcomes remain understudied. We investigated age and sex differences in IBD patients using a nationwide study in Iran, the Iranian Registry of Crohn's and Colitis (IRCC). METHODS The IRCC is a national registry that gathered information on adult IBD patients since 2017. The collected data included demographic information, medication history, disease activity, comorbidities, diagnosis age, prognosis, the extent of ulcerative colitis (UC), Crohn's disease (CD) location, and extraintestinal manifestations. The statistical methods included the independent Student's t-test, Chi-square test, and binary logistic regression, using R version 4.2.2. RESULTS Among the 9,392 IBD patients, 7,496 (3,600 females) and 1,896 (808 females) had UC and CD, respectively. Sex difference showed higher odds of active disease in the past six months in male CD patients (OR 1.24 [95%CI 1.03, 1.49]) vs. females, but in male UC patients, the OR was 0.85 [0.78, 0.93]. Severe disease was less likely in CD patients aged 19-59 and >60 vs. <18. Similarly, UC patients <18 had lower odds of severe disease vs. those aged 19-59 and >60. CONCLUSIONS This study emphasizes the importance of understanding age and sex differences in IBD outcomes. These findings contribute to the ongoing global discussion on IBD management and facilitate the development of targeted interventions and personalized care.

Genomic testing identifies monogenic causes in patients with very early-onset inflammatory bowel disease: a multicenter survey in an Iranian cohort. Clin Exp Immunol 2024; 217:1-11.

Abstract
Patients with very early-onset inflammatory bowel disease (VEO-IBD) may present because of underlying monogenic inborn errors of immunity (IEI). Strong differences have been observed in the causes of monogenic IBD among ethnic populations. This multicenter study was carried out on 16 Iranian patients with VEO-IBD. We reviewed clinical and basic immunologic evaluation including flow cytometry and immunoglobulin levels. All patients underwent clinical whole exome sequencing (WES). Sixteen patients (8 females and 8 males) with a median age of 43.5 months were enrolled. The median age at the onset of symptoms was 4 months. Most patients (12, 75%) had consanguineous parents. Chronic non-bloody diarrhea (13, 81.3%) and perianal diseases including perianal abscess (6, 37.5%), anal fissure (6, 37.5%), or anal fistula (2, 12.5%) were the most common manifestations. WES identified a spectrum of genetic variants in 13 patients (81.3%): IL10RB (6, 37.5%), MVK (3, 18.8%), and CASP8, SLC35C1, G6PC3, and IKBKB in 1 patient, respectively. In 3 patients (18.7%), no variant was identified. Flow cytometry identified a spectrum of abnormalities that helped to assess the evidence of genetic diagnosis. At the end of the survey, 3 (18.8%) patients were deceased. This high rate of monogenic defects with a broad spectrum of genes reiterates the importance of investigating IEI in patients with infantile-onset IBD.

Abstract
BACKGROUND Data on the epidemiology of inflammatory bowel disease (IBD) in the Middle East are scarce. We aimed to describe the clinical phenotype, disease course, and medication usage of IBD cases from Iran in the Middle East. METHODS We conducted a cross-sectional study of registered IBD patients in the Iranian Registry of Crohn's and Colitis (IRCC) from 2017 until 2022. We collected information on demographic characteristics, past medical history, family history, disease extent and location, extra-intestinal manifestations, IBD medications, and activity using the IBD-control-8 questionnaire and the Manitoba IBD index, admissions history, history of colon cancer, and IBD-related surgeries. RESULTS In total, 9746 patients with ulcerative colitis (UC) (n=7793), and Crohn's disease (CD) (n=1953) were reported. The UC to CD ratio was 3.99. The median age at diagnosis was 29.2 (IQR: 22.6,37.6) and 27.6 (IQR: 20.6,37.6) for patients with UC and CD, respectively. The male-to-female ratio was 1.28 in CD patients. A positive family history was observed in 17.9% of UC patients. The majority of UC patients had pancolitis (47%). Ileocolonic involvement was the most common type of involvement in CD patients (43.7%), and the prevalence of stricturing behavior was 4.6%. A prevalence of 0.3% was observed for colorectal cancer among patients with UC. Moreover,15.2% of UC patients and 38.4% of CD patients had been treated with anti-tumor necrosis factor (anti-TNF). CONCLUSION In this national registry-based study, there are significant differences in some clinical phenotypes such as the prevalence of extra-intestinal manifestations and treatment strategies such as biological use in different geographical locations.

Abstract
BACKGROUND It is unknown if the clinical manifestations and phenotype of disease are comparable between early- and elderly-onset inflammatory bowel disease (IBD). We aimed to seek differences in disease phenotype, course, complications, and treatment between early- and elderly-onset IBD patients. METHODS This retrospective cohort study on registered IBD patients in the Iranian Registry of Crohn's and Colitis (IRCC) compared demographics, disease phenotype, disease activity, IBD-related surgery and medications between early- and elderly-onset IBD. A generalized linear regression model was used to investigate the relative risk of age at diagnosis adjusted for gender and disease duration for the outcomes. RESULTS From 10048 IBD patients, 749 with early-onset (7.5%), and 472 (4.7%) elderly-onset IBD were enrolled: 855 (63.1%) ulcerative colitis (UC) and 366 (26.9%) Crohn's disease (CD). Left-sided colitis was more frequent among elderly-onset UC patients (P<0.001). Ileum and ileocolonic locations were the most common types in elderly-onset and early-onset CD patients, respectively. In comparison with elderly-onset UC, early-onset cases more often used prednisolone (22.1% vs. 11.4%, P=0.001), immunomodulators (44.9% vs 25.2%, P<0.001) and anti-tumor necrosis factors (TNF) (20.1% vs 11.9%, P=0.002). Elderly-onset UC patients had 0.7 times lower risk of aggressive phenotype (95%CI:0.6‒0.9, P=0.005). Early-onset CD was associated with higher use of prednisolone (27.7% vs 8.1%, P<0.001), immunomodulators (58.7% vs 41.8%, P=0.005) and anti-TNF (49.6% vs 35.4%, P=0.006). CONCLUSION Early-onset IBD was associated with a more aggressive phenotype and higher prednisolone, immunomodulators, and anti-TNF use.

Abstract
Background: Pharmacotherapy with biologics and small molecules, as the more effective therapies for moderate to severe ulcerative colitis (UC) and Crohn's disease (CD), is complex. Choosing the best methods for their utilization in order to induce and maintain remission are critical for practicing gastroenterologists. We aimed to develop an Iranian consensus on the management of inflammatory bowel disease (IBD) patients with biologics and small molecules. Methods: A Delphi consensus was undertaken by experts who performed a literature summary and voting process. Quality of evidence was assessed using the Grading and Recommendations Assessment, Development, and Evaluation; and an additional risk of bias-protocol. Results: Following an extensive search of the literature, 219 studies were used to determine the quality of the evidence. After three rounds of voting, consensus (defined as≥80% agreement) was reached for 87 statements. Conclusion: We considered different aspects of pharmacotherapy in this consensus. This guideline, along with clinical judgment, can be used to optimize management of IBD patients.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic inflammatory condition involving individuals across all age groups. Recent data suggests the increase in the prevalence of IBD and the surge in applying the biologic drugs in which both change the cost of IBD in recent years. Comprehensive assessment of direct and indirect cost profiles associated with IBD in our area is scarce. This study aimed to determine the economic burden of IBD in Iran from a societal perspective, using cost diaries. METHODS Patients available on clinic registry and hospital information system (HIS), who were diagnosed with IBD, were invited to take part in this study. Demographic and clinical data, the healthcare resource utilization or cost items, absenteeism for the patients and their caregivers were obtained. The cost of the used resources were derived from national tariffs. The data regarding premature mortality in IBD patients was extracted from HIS. Productivity loss was estimated based on the human capital method. Then, cost date were calculated as mean annual costs per patient. RESULTS The cost diaries were obtained from 240 subjects (Ulcerative colitis: n = 168, Crohn's disease, n = 72). The mean annual costs per patient were 1077 US$ (95% CI 900-1253), and 1608 (95% CI 1256, 1960) for the patients with ulcerative colitis and Crohn's disease, respectively. Of the total costs, 58% and 63% were in terms of the indirect costs for the patients with ulcerative colitis and Crohn's disease, respectively. The cost of illness for country was found to be 22,331,079 US$ and 15,183,678 US$ for patients with ulcerative colitis and Crohn's disease, respectively. Highest nationwide economic burden of IBD was found for patients older than 40 years were estimated to be 8,198,519 US$ and 7,120,891 US$, for ulcerative colitis and Crohn's disease, respectively. CONCLUSION The medication was found to be the greatest contributor of direct medical costs. Productivity loss in terms of long-term disability and premature mortality were major components of IBD's economic burden in Iran.

The clinical significance of biliary findings in magnetic resonance enterography of patients with inflammatory bowel disease. Pol J Radiol 2022; 87:e613-e621. [PMID: 36532253 PMCID: PMC9749785 DOI: 10.5114/pjr.2022.121443] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Accepted: 04/18/2022] [Indexed: 08/30/2023] Open
Abstract
PURPOSE Given the association of inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC), we aimed to investigate the clinical relevance of abnormal hepatobiliary findings on magnetic resonance enterography (MRE) of IBD patients considering the risk of over- or underestimation of PSC at MRE. MATERIAL AND METHODS Using the MRE dataset of patients referring to a tertiary hospital and the National Registry of Crohn's and Colitis, 69 MREs, including 23 IBD-PSC, 23 IBD-without PSC, and 23 healthy controls (HC), were retrospectively reviewed by 2 experienced radiologists blinded to the clinical data, to evaluate hepatobiliary abnormalities. Sensitivity, specificity, and likelihood ratios were calculated. RESULTS Bile duct irregularities were the most common finding in the IBD-PSC group, with a frequency of 91%. Intra- and extrahepatic bile duct (IHBD and EHBD) irregularities were observed in 87% and 78% of PSC patients, respectively. Higher frequency of IHBD and EHBD wall thickening, bile duct dilation, EHBD stricture, and periportal oedema were observed in the IBD-PSC group. Peribiliary T2-weighted hyperintensities and contrast-enhancement were significantly more common in the IBD-PSC group than in the IBD and HC groups (48% and 35%, respectively) (p < 0.001). Detection of biliary irregularities on MRE had a specificity of 94% (95% CI: 82-99%), a sensitivity of 91% (95% CI: 72-99%), and a positive likelihood ratio of 14.0 (95% CI: 4.7-42.1) for the diagnosis of PSC. CONCLUSIONS This study emphasizes the importance of assessing and reporting hepatobiliary abnormalities visible in the MRE of patients with IBD to avoid a delayed diagnosis of PSC.

Abstract
BACKGROUND The role of genetic and environmental factors in inflammatory bowel disease's (IBD) clinical course is not fully clear. We aimed to assess the clinical phenotype, disease course, and prognosis of familial IBD in comparison with sporadic cases. METHODS We conducted a prospective national matched case-control study of registered IBD patients in the Iranian Registry of Crohn's and Colitis (IRCC) recruited from 2017 until 2020. Sporadic and familial IBD patients were matched based on age, sex, and disease duration. Data on demographics, past medical disease, family history of IBD, disease type, clinical phenotype, extraintestinal manifestations, IBD medications, IBD activity using the IBD-control-8 questionnaire and the Manitoba IBD index, emergency visits in the past 12 months, admissions in the past 3 months, history of colon cancer, IBD-related surgeries, and aggressive phenotype were gathered. Variable distributions were compared between sporadic and familial cases. RESULTS Overall, 5231 patients with ulcerative colitis (UC, 18.3% familial) and 1438 patients with Crohn's disease (CD, 16.7% familial) were registered in the IRCC. Age at diagnosis was similar between familial and sporadic cases. After matching, 3523 UC patients and 908 CD patients were enrolled in the study. Extraintestinal manifestations, UC extent, CD location and behavior, anti-TNF use, disease activity, colon cancer, IBD-related surgeries and the aggressive phenotype were similar between these sporadic and familial cases. CONCLUSIONS The prevalence of familial UC and CD cases in Iran was more similar to western countries, and family history did not show a predictive value for disease phenotype, course, and outcomes in our study.

Abstract
BACKGROUND: Immunosuppressive agents used in the treatment of inflammatory bowel diseases (IBDs) could potentially increase the risk of coronavirus disease 2019 (COVID-19). We aimed to compare COVID-19 frequency in patients with IBD with their households and identify the related risk factors. METHODS: Firstly, a multi-centered, observational study on 2110 patients with IBD and 2110 age-matched household members was conducted to compare COVID-19 frequency. Secondly, the data of patients with IBD and COVID-19 who had called the COVID-19 hotline were added. Multivariable logistic regression was used to evaluate the effect of age, type and severity of IBD, the number of comorbidities, and medications on the frequency of COVID-19 among the patients with IBD. RESULTS: The prevalence of COVID-19 in patients with IBD and household groups was similar (34 [1.61%] versus 35 [1.65%]; P = 0.995). The prevalence of COVID-19 increased from 2.1% to 7.1% in those with three or more comorbidities (P = 0.015) and it was significantly higher in those with severe IBD (P = 0.026). The multivariable analysis only showed a significant association with anti-TNF monotherapy (OR: 2.5, CI: 0.97-6.71, P = 0.05), and other medications were not associated with COVID-19. CONCLUSION: The prevalence of COVID-19 in patients with IBD was similar to the household members. Only patients with IBD receiving anti-TNF monotherapy had a higher risk of COVID-19 susceptibility. This finding could be attributed to the higher exposure to the virus during administration in health care facilities.

Park SB, Yoon JY, Cha JM. What Are the Different Phenotypes of Inflammatory Bowel Disease in Asia? Gut Liver 2022; 16:676-685.

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.

Middle East J Dig Dis 2022; 14:34-43. [PMID: 36619729 PMCID: PMC9489331 DOI: 10.34172/mejdd.2022.253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 11/01/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND: The rate of hospital readmission is seen as a measure of quality and accountability. Knowing the risk factors that can be changed could reduce the cost burden on patients with inflammatory bowel disease (IBD) and the health system. METHODS: Retrospective analysis was performed on the data extracted from hospital records during a 4-year period. The study setting encompassed three referral hospitals in Tehran and the south of Iran. The primary outcome was hospital readmission of patients with IBD. The factors associated with binary and categorical dependent variables were analyzed using robust logistic regression and multinomial logistic regression, respectively. The significance level was set at P=0.05. RESULTS: 187 patients were admitted during the 4-year study period for an IBD-related reason, among whom 131 patients (70.1%) had ulcerative colitis (UC), and 56 patients (29.9%) had Crohn's disease (CD). Moreover, 29% (55) of the participants had been readmitted at least once during the study period, and seven patients with IBD had been readmitted five or more times during the study period. Corticosteroids (OR=4.55, 95% confidence interval CI: 1.65- 12.55) and chronic pain (OR=6.65, 95% CI: 1.73-25.62) were two factors associated with their readmission within 90 days. For the patients with five or more times of readmissions, Corticosteroids (RRR=5.68), chronic pain (RRR=5.05), length of hospital stay (RRR=0.69), and age (RRR=0.9) could significantly explain the hospital readmissions. CONCLUSION: About one in seven hospitalizations of patients with IBD leads to 30-day readmission. Moreover, younger patients with IBD and shorter length of hospital stay were more likely to be readmitted five or more times during the study period. The use of corticosteroids and the presence of chronic pain were predictors of 90-day readmission. More studies are needed to detect the best management plan for chronic pains.

Abstract
BACKGROUND With an increase in the prevalence and incidence of inflammatory bowel diseases (IBDs), they have become a global challenge. The IBD registry provides complete and timely data, thereby greatly contributing to the estimation of the burden of these diseases and development of control and prevention programs. We aimed to develop an IBD registry software. METHODS The present applied-developmental study had two main stages: determining user requirements, and developing the IBD registry software. The software was created using a Web-based software development technology called ASP.NET Core 2. The programming language in this framework was C#, and the SQL Server 2017 was employed to create a strong and integrated software databank in the relational form. RESULTS When determining user requirements, the data elements were classified into two main categories of patient information and visits and tests. Moreover, in this stage, registry functions, including case ascertainment, abstracting, follow-up, quality control, and reporting were identified. In the registry software development stage, the object-oriented conceptual model was designed with five use case diagrams and 59 classes. The user interface comprised the following main sections: add patient, find patient, complete source report, report, staff, and drugs. Precise user authentication and authorization were also employed to enhance the security of the developed software. CONCLUSION Development of an IBD registry which can precisely record patients and estimate the incidence, prevalence, and socioeconomic burden of these diseases can assist in planning for the control and prevention of IBD in healthcare systems.

Abstract
Background Recently, the role of endogenous microbiota and the genotype-microbiota correlation in inflammatory bowel disease (IBD) pathogenesis have been highlighted. However, fungi, as the second most prevalent residents of the intestine, and their primary receptor, Dectin-1, are underrated. Thus, we conducted the first human study investigating the association of Leucine-rich repeat kinase 2 (LRRK2) polymorphism (rs11564258) with type and the extent of intestinal fungi in IBD patients. Material and methods A case–control study was performed on 79 ulcerative colitis (UC)-patients (case group) and 58 healthy subjects (HS group). DNA was extracted from blood samples of both groups and amplified with the primers designed for the specific locus containing the LRRK2 polymorphism (rs11564258) and then sequenced. Dectin-1 and LRRK2 mRNA expression levels were also determined. Furthermore, the type and prevalence of fecal yeast species were surveyed in case and control groups. Results A positive correlation was observed between rs11564258 polymorphism and UC susceptibility (p = 0.008 vs. HS). Patients with active UC had the highest rate of isolated fungal colonies (50.41%), followed by patients with non-active UC (24.6%) and HS (25%). These results showed a relationship between UC severity with the increased fungal load. Candida albicans had the highest prevalence in both UC (78.7%) and HS groups (55.8%). Whereas Saccharomyces cerevisiae was the second most common species detected in HS (15.23%), it was significantly reduced in the UC patient group (1.68%) (P = 0.0001). On the other hand, single nucleotide polymorphism (SNP, rs11564258) was not correlated with the increased fungal flora in the UC patients. The expression of LRRK2 and Dectin-1 mRNA detected in blood samples was notably higher in the UC patients (P < 0.01) than in the HS group, without being affected by rs11564258 polymorphism. Conclusions Here, we disclosed that LRRK2 mediates Dectin-1 signaling pathway activation and subsequent inflammation in the UC patients without being affected by the presence of SNP rs11564258. Our data showed an increased global fungal load in the UC patients along with elevated UC susceptibility in cases carrying rs11564258 polymorphism. However, more clinical investigations, particularly in larger populations with different ethnic groups, are required to support this conclusion.

Abstract
INTRODUCTION Immunomodulators remain fundamental for the medical treatment of Crohn's disease (CD). Methotrexate (MTX) is widely used as a second-line immunomodulator; however, there is a lack of recent data on MTX monotherapy among the Asian population with CD. Therefore, in this study, we aimed to investigate the tolerability and clinical outcomes of MTX in Korean patients with CD. METHODS A retrospective chart review was performed for CD patients treated with MTX monotherapy or in combination with 5-aminosalicylic acid (5-ASA), at the Asan Medical Center, Seoul, South Korea. The tolerability of MTX monotherapy within 6 months was assessed and the clinical effectiveness of MTX was evaluated based on the Crohn's disease activity index (CDAI). RESULTS In total, 85 patients were included, of which 29 (34.1%) discontinued MTX due to intolerability during the follow-up. Adverse events (AEs) were reported in 41 (48.2%) patients. The most common AE was gastrointestinal disorders (17/41) and only one patient experienced a serious AE, a systemic infection that required hospitalization. Among the 56 patients who tolerated MTX within 6 months, 44 (65.9%) showed a clinical response. Moreover, no factor was significantly associated with intolerability. The administration method was the only factor significantly associated with a response to MTX (p = 0.041). The adjusted odds ratio of parenteral injection compared to oral administration was 5.68 (95% confidence interval (CI), 1.07-30.08). CONCLUSION In this study, one-third of patients were intolerant to MTX; nonetheless, the response rate was as high as 65.9% among tolerant patients. In addition, no significant factors affected intolerability. In terms of the clinical response, parenteral injection could be better than oral administration.

Kim YS. Treatment of inflammatory bowel diseases: focusing on 5-aminosalicylates and immunomodulators. JOURNAL OF THE KOREAN MEDICAL ASSOCIATION 2021.

Abstract
Background: Recently, the incidence and prevalence rates of inflammatory bowel disease (IBD) have increased worldwide, including in Korea. Although there has been considerable progress in the management of IBD following the discovery of biologic agents, 5-aminosalicylate (5-ASA) and immunomodulators are still considered cornerstones in the management of mild to moderate IBD.Current Concepts: 5-ASA plays a key role in inducing remission in patients with mild to moderate ulcerative colitis. High doses of 5-ASA are more effective in inducing remission in patients with moderate ulcerative colitis, and combination therapy of oral 5-ASA and topical 5-ASA agents is recommended. Although the effect of 5-ASA in patients with Crohn disease is limited, high doses of 5-ASA can be effective for patients with mild disease, inflammatory behavior, and colonic involvement. Maintaining remission is essential for patients with IBD. Good doctor-patient relationships and encouraging drug adherence are recommended. Regarding drug adherence, a once-daily regimen is preferred for patients’ satisfaction. Thiopurines, the most important immunomodulators, show therapeutic benefits, such as steroid-sparing effects and remission maintenance in ulcerative colitis and Crohn disease after induction therapy. However, several side effects, including severe leukopenia, can induce the discontinuation of thiopurines. Close monitoring and management decisions should be individualized according to the risk of relapse and adverse events.Discussion and Conclusion: In conclusion, 5-ASA and immunomodulators are cornerstones in the management of IBD. As such, clinicians should have knowledge of these drugs and patients’ characteristics for proper prescription.

Enteroscopy in Crohn's Disease: Are There Any Changes in Role or Outcomes Over Time? A KASID Multicenter Study. Gut Liver 2021; 15:375-382. [PMID: 32616680 PMCID: PMC8129664 DOI: 10.5009/gnl20023] [Citation(s) in RCA: 6] [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: 01/15/2020] [Revised: 04/17/2020] [Accepted: 04/29/2020] [Indexed: 12/21/2022] Open
Abstract
Background/Aims Although balloon-assisted enteroscopy (BAE) enables endoscopic visualization of small bowel (SB) involvement in Crohn's disease (CD), there is no data on the changes in outcomes over time. We therefore investigated the changes in BAE use on CD patients over different time periods in terms of its role and clinical outcomes. Methods We used a multicenter enteroscopy database to identify CD patients with SB involvement who underwent BAE (131 procedures, 116 patients). We compared BAE-related factors and outcomes between the first period (70 procedures, 60 patients) and the second period (61 procedures, 56 patients). The specific cutoff point for dividing the two periods was 2007, when BAE guidelines were introduced. Results Initial diagnosis of SB involvement in CD was the most common indication for BAE during each period (50.0% vs 31.1%, p=0.034). The largest change was in the number of BAE uses for stricture evaluation and/or treatment, which increased significantly in the latter period (2.9% vs 21.3%, p=0.002). The diagnostic yield in patients with suspected CD was 90.7% in the first period and 95.0% in the second (p=0.695). More endoscopic interventions were performed in the second period than in the first (5.1% vs 17.6%, p=0.041). Enteroscopic success rates were high throughout (100% in the first period vs 80.0% in the second period, p>0.999). In the first and second periods, therapeutic plans were adjusted in 62.7% and 61.4% of patients, respectively. Conclusions The overall clinical indications, outcomes, and effectiveness of BAE were constant over time in CD patients with SB involvement, with the exception that the frequency of enteroscopic intervention increased remarkably.

Abstract
Background/Aims The national registry for inflammatory bowel disease (IBD) was designed to study epidemiology and prescribing pattern of treatment of IBD in India. Methods A multicenter, cross-sectional, prospective registry was established across four geographical zones of India. Adult patients with ulcerative colitis (UC) or Crohn’s disease (CD) were enrolled between January 2014 and December 2015. Information related to demographics; disease features; complications; and treatment history were collected and analyzed. Results A total of 3,863 patients (mean age, 36.7 ± 13.6 years; 3,232 UC [83.7%] and 631 CD [16.3%]) were enrolled. The majority of patients with UC (n = 1,870, 57.9%) were from north, CD was more common in south (n = 348, 55.5%). The UC:CD ratio was 5.1:1. There was a male predominance (male:female = 1.6:1). The commonest presentation of UC was moderately severe (n = 1,939, 60%) and E2 disease (n = 1,895, 58.6%). Patients with CD most commonly presented with ileocolonic (n = 229, 36.3%) inflammatory (n = 504, 79.9%) disease. Extraintestinal manifestations were recorded among 13% and 20% of patients in UC and CD respectively. Less than 1% patients from both cohorts developed colon cancer (n = 26, 0.7%). The commonly used drugs were 5-aminosalicylates (99%) in both UC and CD followed by azathioprine (34.4%). Biologics were used in only 1.5% of patients; more commonly for UC in north and CD in south. Conclusions The national IBD registry brings out diversities in the 4 geographical zones of India. This will help in aiding research on IBD and improving quality of patient care.
