Abstract
BACKGROUND Inflammatory bowel disease (IBD) consists of two main types: Crohn's disease (CD) and ulcerative colitis (UC). The epidemiology of IBD patients has not been comprehensively studied in EMRO countries; therefore, we conducted this meta-analysis to study the epidemiology of this disease in these countries. METHODS We searched four international databases, namely Scopus, Web of Knowledge (ISI), Medline/PubMed, and ProQuest, from inception up to the end of May 2023. The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guideline was used to carry out this systematic review and meta-analysis investigation. Using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist, the quality of the selected papers was assessed. RESULTS Based on the results of this study, the incidence of UC in EMRO countries was 2.65 per 100,000 (95% CI: 1.39-3.90), and the incidence of CD was 1.16 per 100,000 (95% CI: 0.73-1.59). The most commonly involved intestinal segment in CD was the terminal ileum (44.7%, 95% CI: 34.7-55.2), followed by the ileum (29.8%, 95% CI: 22.2-38.6), and colon (18.7%, 95% CI: 10.8-30.4). However, in UC patients, extensive colitis was the most common finding (32.3%, 95% CI: 26.4-38.8), followed by proctosigmoiditis (27.9%, 95% CI: 21.1-35.8), left-sided colitis (27.4%, 95% CI: 22.7-32.7), and proctitis (22.6%, 95% CI: 17.5-28.5). CONCLUSION As a result, we were able to establish the traits of IBD patients in EMRO nations. UC patients had a higher incidence than CD patients. The most common regions of involvement in CD and UC patients, respectively, were the colon and pancolitis. Compared to UC patients, CD patients had a higher history of appendectomy.

Abstract
Background Inflammatory bowel disease which is subgrouped mainly to ulcerative colitis and Crohn's disease is thought to be a multi-organ disease. Most organs can be involved in the disease course in addition to gastrointestinal tract involvement. In this systematic review we aimed to assess the prevalence of these manifestations in Eastern Mediterranean Regional Office (EMRO) countries. Method The present systematic review and meta-analysis study was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guideline. Joanna Briggs Institute (JBI) Critical Appraisal Checklist was admired for the quality evaluation of the included studies. For determining the heterogeneity, we used Cochran test and I2 statistics. Result Finally, 12 studies were included in our study. Based on the results of our study the prevalence of arthritis in ulcerative colitis and Crohn's disease patients was 7.1% (95% CI: 2.6-18.2%) and 13.5% (95% CI: 2.6-47.3%), respectively. Prevalence of arthralgia in ulcerative colitis patients was 18.4% (95% CI: 14.3-23.3%). skin involvement prevalence was 9.9% (95% CI 4.7-19.6%) in inflammatory bowel disease (IBD) patients. ocular involvement prevalence was 7.2% (95% CI 17-25.8%) in IBD patients. PSC prevalence in ulcerative colitis and Crohn's disease patients was 3.5% (95% CI: 1.7-7.3%) and 2.7% (95% CI: 1.3-5.5%), respectively. Conclusion Based on the results of this study arthralgia and arthritis were the most common extra-intestinal manifestation of IBD followed by dermatologic and ocular involvements. This extra-intestinal manifestation can challenge the patients' management and identifying their pattern is important during the disease course.

Abstract
Inflammatory bowel disease (IBD) applies to two main forms of chronic relapsing inflammatory intestinal disorders: Crohn's disease (CD), Ulcerative colitis (UC). CD requires an irregular immune reaction that induces intense inflammation. The cause of CD disease is not yet fully known; previous research, however, indicated inflammation of the intestines elevated or continues due to inappropriate immune responses due to associations between genetic factors, intestinal microbiota, and environmental factors contributing to the production of IBD. This study aimed to investigate predisposing genes, single nucleotide Polymorphisms (SNPs) NOD1/CARD4 and NOD2/CARD15) with CD in Iraqi patients. The common NOD1 (G796A) SNP and NOD2 SNPs R702W, G908R and L1007fsinC for NOD2 SNPs were selected. Thirty Iraqi citizens with a recognized diagnosis of CD and twenty apparently healthy controls were included in the study from November 2019 to December 2020; the common NOD1 and NOD2 polymorphisms have been screened by the polymerase chain reaction/restriction analysis length polymorphism (PCR/RFLP). The results of the current investigation for NOD1 polymorphism in studied patients and controls, the allelic and genotypic data show a highly significant association of G796A SNPs in the NOD1 with Crohn's disease, GA percentage was 56.67% in patients as compared to controls genotype was (0.00%).
Furthermore, the G allele was more common in Crohn's patients than the A allele 0.72 vs. 0.28. Also, the allelic and genotypic frequency distribution of the studied NOD2 SNPs in the current study were (R702W, G908R, and L1007fs) in Iraqi patients, and controls revealed a highly significant connection between the G908R SNP with Crohn's disease susceptibility. The proportion of the genotype GC was 30% in patients while 0% in the control group, the frequency of the G allele was 0.85 vs 0.15 respectively, which was more than the frequency of the A allele. There were no significant changes in genotypic and allelic frequencies of the R702W and L1007fs SNPs in Iraqi Crohn's disease patients. The present study concluded that the NOD1 SNP of allelic and genotypic data show a highly significant association of G796A with a predisposition to Crohn's disease in Iraqi patients. And the NOD2 SNPs of G908R were also revealed to be highly effective. While the other studied SNPs were R702W and L1007fsinsC of NOD2, which showed no significant changes in the allelic and genotypic frequencies of the SNPs with Crohn's disease Iraqi patients.

Abstract
Objectives Despite the recent findings of the rising incidence of inflammatory bowel disease (IBD) in Arab countries, there are limited data on the characteristics of IBD patients and the disease course in the Arab world. This systematic review aimed to investigate the incidence and epidemiology of IBD in the Arab world. Material and Methods We conducted a systematic literature review that utilized a comprehensive search of PubMed, Cochrane Central, SCOPUS, Google Scholar, and Web of Science from their inception till August 2020. We included cross-sectional, prospective, and retrospective studies that examined the prevalence and/or epidemiological characteristics of IBD in Arab countries. Results A total of 16 studies that examined IBD in Saudi Arabia, Egypt, Kuwait, the United Arab Emirates, Bahrain, Lebanon, and Oman were included. Generally, the included studies covered the period from the early 1990s to the late 2010s. A total of 1,627 ulcerative colitis (UC) patients and 1,588 Crohn's disease (CD) patients were included in this systematic review. The mean age at diagnosis ranged from 24.13 to 43.6 years in adult cases and from 4.5 to 16 years in pediatric cases. In most of the included studies, the majority of patients were male. The quantitative analysis revealed a pooled incidence rate of 2.33 (95% confidence interval [CI] 1.2-3.4) per 100,000 persons per year for UC in the Arab world. Likewise, the pooled incidence rate for CD in the Arab world was 1.46 (95% CI 1.03-1.89) per 100,000 persons per year. Conclusion There is a growing incidence of IBD in the Arab world, while IBD patients from Arab countries may present with some different characteristics, compared to their counterparts in Europe.

Abstract
BACKGROUND There are currently no nationwide data on the epidemiology of inflammatory bowel diseases (IBD) in Israel. We aimed to determine the population-based epidemiological trends of IBD in the diverse Israeli population. METHODS Health-administrative data were retrieved from all 4 Israeli health maintenance organizations, insuring 98% of the population, using validated identification algorithms. National trends were determined using Joinpoint regression analysis calculating annual percent change and average annual percent change (AAPC). RESULTS By 2019, there were 46,074 patients with IBD in Israel, corresponding to a national prevalence of 519/100,000 (0.52%), of whom 54.1% had Crohn disease (CD) and 45.9% had ulcerative colitis (UC). The number of Jewish patients doubled from 18,701 in 2005 (354/100,000) to 38,950 (589/100,000) in 2018 (AAPC, +4.0%; P < 0.05), and the number of Arab patients increased 3-fold from 1096 (102.1/100,000) to 3534 (240.7/100,000; AAPC, +6.8%; P < 0.05) during the same years. However, the increase rate has gradually decelerated over time (annual percent change during 2005-2008, 2009-2014, and 2005-2018 was +6.7%, +4.2%, and +2.3%, respectively; P < 0.05). Pediatric prevalence increased from 37.4 to 52.2/100,000, with CD predominating in both Jews and Arabs. The incidence of CD remained stable (from 15.9/100,000 to 14.9/100,000) and the incidence of UC decreased (15.4/100,000 to 10.5/100,000 (AAPC, -3.2%; P < 0.001)). In contrast, pediatric incidence of CD increased from 7.3/100,000 to 8.3/100,000 (AAPC, +1.9%; P < 0.05) and that of UC increased from 2.6 to 4.4/100,000 (AAPC, +5.8%; P < 0.05). CONCLUSIONS The IBD prevalence rate in Israel is still increasing but gradually decelerating, probably due to the decreasing overall IBD incidence. Nonetheless, incidence rate in children is still increasing. Ongoing narrowing in the rates between Jews and Arabs over time may indicate shared environmental factors.

Abstract
BACKGROUND Nucleotide-binding oligomerization domain-containing two (NOD2/CARD15) gene polymorphisms are implicated in the pathogenesis of Crohn's disease (CD). AIM To describe the allelic frequency of NOD2/CARD15 gene variants among Kuwaiti patients with CD and investigate potential genotype/phenotype associations. METHODS Adult Kuwaiti citizens with an established diagnosis of CD and healthy controls were enrolled from October 2018 to May 2020. Three common NOD2/CARD15 polymorphisms (R702W, G908R, and L1007fs) and P268S and IVS8+158 polymorphisms were screened by polymerase chain reaction/restriction analysis length polymorphism (PCR/RFLP). RESULTS Ninety adult Kuwaiti patients with CD and 210 healthy subjects (as controls) were recruited. P268S, IVS8+158, G908R, and R702W minor alleles were identified in 38.9%, 21.1%, 12.2%, and 4.4% of CD patients, respectively. NOD2/CARD15 polymorphisms coexisted in 35 healthy controls (16.7%) and 21 CD patients (23.3%). Individuals with either a single or multiple polymorphism were approximately two times more likely to have CD than those with no polymorphism. Patients with multiple polymorphisms had significantly more stricturing and penetrating disease. CONCLUSION NOD2/CARD15 gene polymorphisms were significantly associated with an increased risk of disease and aggressive phenotypes among the Kuwaiti CD population.

Abstract
Ulcerative colitis is an idiopathic, chronic, inflammatory bowel disorder characterized by an unpredictable course of alternating cycles of relapse and remission. Traditionally viewed as a disease of Western countries, the prevalence of ulcerative colitis is reported to be increasing in the developing world. In these regions, there is the potential to further explore the etiology of the disease, mainly through genetic studies. With this in mind, we consider available data relating to the epidemiology, clinical manifestations, and disease course of ulcerative colitis in Africa and the Middle East. Current treatment approaches in these countries are also reviewed and discussed in the context of new, small molecule, orally administered therapies. Areas covered: Available data on the epidemiology, clinical manifestations, and risk factors of ulcerative colitis in Africa and the Middle East are reviewed using a PubMed database search. Expert commentary: Epidemiologic studies from African and Middle Eastern countries suggest disease trends similar to the West, and an important health and economic burden. The management of ulcerative colitis within these developing countries is challenging, with the need to improve early diagnosis, access to healthcare, and patient education, along with facilitation of access to treatment options and improvement of medication adherence.
