Abstract
BACKGROUND Ustekinumab and tofacitinib have recently been approved for the management of moderate to severe ulcerative colitis (UC). However, there is no evidence on how they should be positioned in the therapeutic algorithm. The aim of this study was to compare tofacitinib and ustekinumab as third-line therapies in UC patients in whom anti-TNF and vedolizumab had failed. METHODS This was a multicenter retrospective observational study. The primary outcome was disease progression, defined as the need for steroids, therapy escalation, UC-related hospitalization and/or surgery. Secondary outcomes were clinical remission, normalization of C-reactive protein, endoscopic remission, treatment withdrawal, and adverse events. RESULTS One-hundred seventeen UC patients were included in the study and followed for a median time of 11.6 months (q1 -q3, 5.5-18.7). Overall, 65% of patients were treated with tofacitinib and 35% with ustekinumab. In the entire study cohort, 63 patients (54%) had disease progression during the follow-up period. Treatment with ustekinumab predicted increased risk of disease progression compared to treatment with tofacitinib in Cox regression analysis (HR: 1.93 [95% CI: 1.06-3.50] p = 0.030). Twenty-eight (68%) patients in the ustekinumab group and 35 (46%) in the tofacitinib group had disease progression over the follow-up period (log-rank test, p < 0.054). No significant differences were observed for the secondary outcomes. Six and 22 adverse events occurred in the ustekinumab and tofacitinib groups, respectively (15% vs. 31%, p = 0.11). CONCLUSIONS Tofacitinib was more efficacious in reducing disease progression than ustekinumab in this cohort of refractory UC patients. However, prospective head-to-head clinical trials are needed as to confirm these data.

Abstract
We report a 19-year-old male with congenital, combined deficiency of immunoglobulin (Ig) E and 2/4 subclasses of IgG (G1, G3) and chronic diarrhea. He presented at six years of age with chronic recurrent diarrhea responsive to immunoglobulin treatment. Initially, it was considered of infectious origin. However, at the age of 14 years, ileocolonoscopy and magnetic resonance enterography (MRE) were performed, and they showed a mild, limited, non-specific, terminal ileitis with increased eosinophil count on histology. A diagnosis of possible eosinophilic gastroenteritis was made, and budesonide was administered with temporary relief. However, at the age of 19 years, repeat ileocolonoscopy showed multiple ulcers in the terminal ileum and aphthous ulcers in the cecum, and repeat MRE demonstrated extensive ileal involvement. Esophagogastroduodenoscopy demonstrated the involvement of the upper GI tract with aphthous ulcers. Subsequently, gastric, ileal, and colonic biopsies revealed Ziehl-Neelsen-negative, non-caseating granulomas. We hereby report the first case of IgE and selective IgG1 and IgG3 deficiency complicated with Crohn's disease-like extensive GI involvement.

Abstract
BACKGROUND Chronic diseases, such as IBD, can lead to anxiety and depression which can have a significant impact on productivity at work [presenteeism]. The aim of this study was to assess the prevalence of depression/anxiety, presenteeism and exercise levels among IBD patients. METHODS This was a multicentre study whereby adult IBD patients, in clinical remission, were asked to answer a questionnaire anonymously. Hospital Anxiety and Depression Score [HADS], Stanford Presenteeism Scale [SPS-6] and Godin Exercise Score were also collected. RESULTS A total of 585 patients were recruited. The majority had Crohn's disease [CD, 62.2%] and were male [53.0%], with a median age of 39 years [IQR 30-49]. A psychiatric diagnosis was present in 10.8% of patients prior to their IBD diagnosis. A further 14.2% of patients were psychiatrically diagnosed after IBD diagnosis, this being commoner in CD patients [41.6% of CD, p <0.01]. A raised HADS-Anxiety or a HADS-Depression score ≥8 was present in 46.1% of patients, with 27.4% having a score ≥11. Low presenteeism at work was present in 34.0%. Patients diagnosed with depression/anxiety had a more sedentary lifestyle [p <0.01], lower presenteeism at work [p <0.01] and a higher rate of unemployment [p <0.01]. CONCLUSIONS A significant percentage of IBD patients in remission suffer from anxiety and/or depression. Risk factors for these are CD, female gender, use of biologic medications, long-standing and/or perianal disease. Depression/anxiety was associated with a sedentary lifestyle, lower presenteeism at work and unemployment. Validated screening tools and appropriate referrals to psychologists and/or psychiatrists should be employed within IBD clinics.

Abstract
INTRODUCTION Anti-SARS-CoV-2 vaccine clinical trials did not include patients with immune-mediated conditions such as inflammatory bowel disease [IBD]. We aimed to describe the implementation of anti-SARS-CoV-2 vaccination among IBD patients, patients' concerns, and the side effect profile of the anti-SARS-CoV-2 vaccines, using real-world data. METHODS An anonymous web-based self-completed survey was distributed in 36 European countries between June and July 2021. The results of the patient characteristics, concerns, vaccination status, and side effect profile were analysed. RESULTS In all 3272 IBD patients completed the survey, 79.6% had received at least one dose of anti-SARS-CoV-2 vaccine, and 71.7% had completed the vaccination process. Patients over 60 years old had a significantly higher rate of vaccination [p < 0.001]. Patients' main concerns before vaccination were the possibility of having worse vaccine-related adverse events due to their IBD [24.6%], an IBD flare after vaccination [21.1%], and reduced vaccine efficacy due to IBD or associated immunosuppression [17.6%]. After the first dose of the vaccine, 72.4% had local symptoms and 51.4% had systemic symptoms [five patients had non-specified thrombosis]. Adverse events were less frequent after the second dose of the vaccine and in older patients. Only a minority of the patients were hospitalised [0.3%], needed a consultation [3.6%], or had to change IBD therapy [13.4%] after anti-SARS-CoV-2 vaccination. CONCLUSIONS Although IBD patients raised concerns about the safety and efficacy of anti-SARS-CoV-2 vaccines, the implementation of vaccination in those responding to our survey was high and the adverse events were comparable to the general population, with minimal impact on their IBD.

Abstract
Background Data on the effectiveness of anti-tumor necrosis factor medications in patients with Crohn's disease (CD) with poor prognostic factors (PPFs) are scarce. This study aimed to generate real-world evidence on the effect of early (≤24 months after diagnosis) vs delayed (>24 months) initiation of adalimumab (ADL) on the 26-week remission rate (Harvey-Bradshaw Index ≤4) in these patients. Methods This multicentre, retrospective, chart review study performed in 10 Greek hospitals enrolled adult patients with moderate to severe CD (Harvey-Bradshaw Index ≥8) with ≥3 PPFs who were initiated on ADL ≥12 months before enrollment. A sample size of 164 patients (early:delayed cohort allocation ratio, 30:70) was required to address the primary endpoint. Results Eligible patients (n = 171) were consecutively enrolled. In the early vs delayed cohorts, the 26-week remission rates (off-steroids) using the last-observation-carried-forward imputation method were 60.7% (37/61) vs 47.2% (50/106), respectively (Δ = 13.5%, P = .044). The respective remission rates were 61.2% vs 42.4% among anti-tumor necrosis factor-naive patients (P = .023) and 58.3% vs 53.2% among anti-tumor necrosis factor-experienced patients (P = .374). The 52-week remission rates using as-observed data were 78.8% and 60.3%, and the intestinal resection rates were 6.5% and 11.9% in the early vs delayed ADL cohorts, respectively. Conclusions Patients with CD with PPFs who received early vs delayed treatment with ADL achieved higher clinical response and remission rates. This effect was more pronounced in those patients who were bio-naive and steroid-dependent/refractory with concurrent extraintestinal manifestations than those who were not.

Abstract
BACKGROUND Interstitial lung [ILD] disease and granulomatous lung disease [GLD] are rare respiratory disorders that have been associated with inflammatory bowel disease [IBD]. Clinical presentation is polymorphic and aetiology is unclear. METHODS This was an ECCO-CONFER project. Cases of concomitant ILD or GLD and IBD, or drug-induced ILD/GLD, were collected. The criteria for diagnosing ILD and GLD were based on definitions from the American Thoracic Society and the European Respiratory Society and on the discretion of reporting clinician. RESULTS We identified 31 patients with ILD. The majority had ulcerative colitis [UC] [n = 22]. Drug-related ILD was found in 64% of these patients, 25 patients [80.6%] required hospitalisation, and one required non-invasive ventilation. The causative drug was stopped in all drug-related ILD, and 87% of patients received systemic steroids. At follow-up, 16% of patients had no respiratory symptoms, 16% had partial improvement, 55% had ongoing symptoms, and there were no data in 13%. One patient was referred for lung transplantation, and one death from lung fibrosis was reported. We also identified 22 GLD patients: most had Crohn's disease [CD] [n = 17]. Drug-related GLD was found in 36% of patients and 10 patients [45.4%] required hospitalisation. The causative drug was stopped in all drug-related GLD, and 81% of patients received systemic steroids. Remission of both conditions was achieved in almost all patients. CONCLUSIONS ILD and GLD, although rare, can cause significant morbidity. In our series, over half of cases were drug-related and therefore focused pharmacovigilance is needed to identify and manage these cases.

Abstract
AIM To evaluate the uptake of screening colonoscopy among physicians as compared to the general population. METHODS Asymptomatic physicians, aged 45-67 years, at average risk for colorectal cancer (CRC), working in the participating National Health System hospitals were asked to complete a questionnaire regarding the uptake of screening colonoscopy. The results were compared to those in a background healthy population, aged 50-75 years, inhabitants of a Greek county, who were offered a free access to a screening colonoscopy program for CRC. High-risk adenomas were those ≥10 mm in diameter or any adenoma, regardless of size, with villous histology or high-grade dysplasia. RESULTS Overall, 267 of 782 physicians and 402 of 6,534 nonphysicians underwent a screening colonoscopy (uptake rates 34.2 and 6.2% respectively, p = 0.00001). Screening colonoscopy has yielded 4 adenocarcinomas (1.6%), 14 high-risk adenomas (5.5%), and 61 low-risk adenomas (25.7%) in the physicians' group. Corresponding figures in the nonphysician arm were 4 (1), 26 (6.5), and 107 (26.6%), respectively. The main reason among physicians for nonadherence was indifference/negligence (n = 213). CONCLUSION The proportion of physicians undergoing screening colonoscopy for CRC is significantly higher compared to the general population; however, it does remain suboptimal.

Abstract
Background and study aims Colonic polypectomy is acknowledged to be a technically challenging part of colonoscopy. Training in polypectomy is recognized to be often inconsistent. This study aimed to ascertain worldwide practice in polypectomy training. Patients and methods An electronic survey was distributed to endoscopic trainees and trainers in 19 countries asking about their experiences of receiving and delivering training. Participants were also asked about whether formal polypectomy training guidance existed in their country. Results Data were obtained from 610 colonoscopists. Of these responses, 348 (57.0 %) were from trainers and 262 (43.0 %) from trainees; 6.6 % of trainers assessed competency once per year or less often. Just over half (53.1 %) of trainees had ever had their polypectomy technique formally assessed by any trainer. Approximately half the trainees surveyed (51.1 %) stated that the principles of polypectomy had only ever been taught to them intermittently. Of those trainees with the most colonoscopy experience, who had performed over 500 procedures, 48.2 % had had training on removing large polyps of over 10 mm; 46.2 % (121 respondents) of trainees surveyed held no record of the polypectomies they had performed. Only four of the 19 countries surveyed had specific guidelines on polypectomy training. Conclusions A significant number of competent colonoscopists have never been taught how to perform polypectomy. Training guidelines worldwide generally give little direction as to how trainees should acquire polypectomy skills. The learning curve for polypectomy needs to be defined to provide reliable guidance on how to train colonoscopists in this skill.

Abstract
BACKGROUND & AIMS Comparative data on budesonide vs mesalamine for the treatment of mild-to-moderately active Crohn's disease (CD) are sparse. We assessed the efficacy and safety of each therapy in patients with mildly to moderately active CD. METHODS We performed a randomized, double-blind, double-dummy, 8-week, multicenter study in which 309 patients with mildly to moderately active CD received pH-modified-release oral budesonide (9 mg/day once daily or 3 mg/day 3 times daily) or Eudragit-L-coated oral mesalamine (4.5 g/day). RESULTS The primary efficacy variable, clinical remission (defined as Crohn's Disease Activity Index ≤150), at the final visit occurred in 69.5% (107 of 154) of patients given budesonide vs 62.1% (95 of 153) of patients given mesalamine (difference, 7.4%; 95% repeated confidence interval, -4.6% to 18.0%; P = .001 for noninferiority). Clinical remission rates did not differ significantly between the 2 budesonide groups. Treatment response, defined as Crohn's Disease Activity Index of 150 or less and/or a decrease of 70 or more (Δ70) or 100 or more (Δ100) points from baseline to final visit, did not differ significantly between patients given budesonide vs mesalamine (Δ70, P = .11; Δ100, P = .15), or between the 2 budesonide groups (Δ70, P = .38; Δ100, P = .78). No other efficacy end points differed significantly between groups. Discontinuation because of adverse events occurred in 3% and 5% of budesonide- and mesalamine-treated patients, respectively. There were no clinically relevant differences in adverse events between the 2 budesonide groups. CONCLUSIONS Budesonide (9 mg/day) was numerically, but not statistically, more effective than Eudragit-L-coated mesalamine (4.5 g/day) in patients with mildly to moderately active CD. Budesonide (9 mg/day), administered once daily, was as effective as the standard (3 times daily) regimen.

Abstract
Human colonic epithelial cells express T helper type 1 (Th1)-associated chemoattractants, yet little is known about the production of Th2-associated chemoattractants. CCL11/eotaxin-1, CCL24/eotaxin-2 and CCL26/eotaxin-3 are known to attract CCR3-expressing, Th2-polarized lymphocytes. We studied constitutive and inflammation-induced expression and production of CCR3 together with its ligands in the colon and peripheral blood of patients with inflammatory bowel disease (IBD) by flow cytometry, reverse transcription–polymerase chain reaction (RT–PCR) and enzyme-linked immunosorbent assay (ELISA). We further defined the regulated expression of these chemokines by RT–PCR and ELISA using cultured human epithelial cell lines. A higher fraction of peripheral T lymphocytes were found to be positive for CCR3 in patients with ulcerative colitis (UC) compared to Crohn’s disease (CD), while almost no CCR3(+) T cells were found in normal controls (NC). Similarly, higher and more frequent expression of CCR3 was observed in colonic biopsies from patients with UC, regardless of the disease activity, when compared to CD or NCs. Serum CCL11/eotaxin-1 was increased significantly in UC (306 ± 87 pg/ml) and less so in CD (257 ± 43 pg/ml), whereas CCL24/eotaxin-2, and CCL26/eotaxin-3 were increased only in UC. Colonic expression of the three chemokines was minimal in NCs but high in inflammatory bowel diseases (especially UC) and was independent of disease activity. Th2, and to a lesser extent Th1, cytokines were able to induce expression and production of all three eotaxins from colonic epithelial cells in culture. CCR3 and ligands over-expression would appear to be a characteristic of UC. The production of CCR3 ligands by human colonic epithelial cells suggests further that epithelium can play a role in modulating pathological T cell-mediated mucosal inflammation.

Abstract
PURPOSE To evaluate the clinical relevance of circulating CEACAM5mRNA-positive cells in patients with operable colorectal cancer (CRC). METHODS Peripheral blood was obtained from 265 patients with operable CRC before the initiation of adjuvant systemic therapy from 96 normal donors and RNA prepared from the Lovo and ARH-77 CRC and leukemic cell lines, respectively, was used as positive and negative controls. The detection of CEACAM5mRNA-positive cells was done using a real-time PCR assay. The association with known prognostic factors and the effect of CEACAM5mRNA-positive cells on patients' prognosis was investigated. RESULTS The analytical detection limit of the method was found to correspond to 0.7 Lovo cell equivalence/5 μg RNA, with a sensitivity of 1 tumor cell/10(5) normal cells and a specificity of 97%. Ninety-eight (37%) patients had detectable circulating CEACAM5mRNA-positive cells. Detection of CEACAM5mRNA-positive cells was significantly associated with higher relapse rate (P < 0.001), decreased disease-free survival (DFS; P < 0.001), higher death rate (P = 0.017), and decreased median overall survival (P = 0.025). Multivariate analysis revealed that the detection of circulating CEACAM5mRNA-positive cells was an independent prognostic factor for decreased DFS [HR = 3.4; 95% CI: 2.0-5.9; P < 0.001]. CONCLUSIONS Detection of peripheral blood CEACAM5mRNA-positive cells is an adverse prognostic factor correlated with poor clinical outcome in patients with operable CRC.

Abstract
Anemia is a common complication of inflammatory bowel diseases. An international working party has formed and developed guidelines for evaluation and treatment of anemia and iron deficiency that should serve practicing gastroenterologists. Within a total of 16 statements, recommendations are made regarding diagnostic measures to screen for iron- and other anemia-related deficiencies regarding the triggers for medical intervention, treatment goals, and appropriate therapies. Anemia is a common cause of hospitalization, prevents physicians from discharging hospitalized patients, and is one of the most frequent comorbid conditions in patients with inflammatory bowel disease. It therefore needs appropriate attention and specific care.

Abstract
BACKGROUND In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning. AIMS To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis. METHODS A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non-surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease. RESULTS A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13-2.10)) whereas age >/=40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70-0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21-0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32-7.89)). CONCLUSIONS A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North-South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres.

Abstract
Patients with ulcerative colitis have an increased risk for developing colon cancer compared to the general population. The risk is related to the extension of the disease and its duration. This risk is the same for Crohn's colitis patients of equal extension and duration. By chemoprevention we mean the use of specific natural or synthetic chemical agents to reverse, suppress or prevent progression to invasive cancer. The chemopreventive agents for colon cancer are either of natural origin (vitamins, minerals, food constituents) or synthetic chemicals (difluoromethyl ornithine) and pharmaceutical agents (aspirin, oltipraz). Apart from folate, no other agent has so far been used in vivo for the prevention of colon cancer in long-standing inflammatory bowel disease. The use of folate was, however, not primarily intended to prevent cancer but to enhance folate absorption in ulcerative colitis. From retrospective studies, within the framework of cancer surveillance programmes, it became evident that folate supplementation may play a positive role as a chemopreventive agent against colorectal cancer in patients with long-standing, extensive ulcerative colitis. There is also evidence suggesting that folate supplementation may contribute to regulation of rectal cell proliferation in ulcerative colitis patients. There is a real need for multicentre, randomized, prospective clinical studies in order to evaluate the promising role of folate in preventing colorectal cancer in patients with long-standing inflammatory bowel disease.

Abstract
OBJECTIVE To study the incidence of ulcerative colitis and to analyse the pattern of the disease in the prefecture of Heraklion, Crete. PARTICIPANTS The population at risk comprised 263,670 inhabitants in the prefecture of Heraklion (2641 km2). The two regional hospitals, five health centres, 109 private family doctors and 145 specialists participated in the study. METHODS A prospective and population-based epidemiological study of ulcerative colitis over five years from 1990 to the end of 1994. RESULTS Overall, 117 patients with ulcerative colitis (75 males and 42 females) were newly diagnosed during the study period. The mean annual incidence of the disease for the years 1990-1994 was 8.9 per 10(5) inhabitants (95% CI 7.2-10.4). The male to female ratio was 1.8:1. There were no significant difference between the age-specific incidences of the age groups. The majority (51.3%) of the patients were exsmokers and one-third had never smoked. A family history of first-degree relatives positive for inflammatory bowel disease was obtained in 9.6% of our patients. CONCLUSION Ulcerative colitis is common in Crete; its incidence is as high as in Northern Europe.

Abstract
BACKGROUND There has been an impression from published work that Crohn's disease is less common in southern than in northern Europe. A low incidence of Crohn's disease has been observed in Greece, but conclusive data are still lacking. METHOD A 5-year prospective and population-based epidemiologic study of Crohn's disease was carried out in a well-defined area of Crete. RESULTS The mean annual incidence of the disease for the years 1990-94 was 3.0 per 10(5) inhabitants. During the study period the incidence increased from 1.9/10(5) in 1990 to 3.8/10(5) in 1994. The male to female ratio was 2.4:1. The age group 25-34 years had the highest age-adjusted incidence (6.3/10(5)). The incidence of Crohn's disease was also found to be higher in smokers, in urban areas, and in people with high educational level. CONCLUSION Crohn's disease is common in Heraklion, Crete. The findings of the study are discussed in relation to those of other European countries.

Abstract
In 153 patients with IBD, 64 with Crohn's disease (CD), and 89 with ulcerative colitis (UC), as well as in 54 healthy controls (HC), the frequencies of four known di-allelic polymorphisms in the genes for TNF-alpha and lymphotoxin alpha (LTalpha) were investigated. In the Dutch population, the alleles of these four polymorphisms are present in only five combinations, called TNF haplotypes: TNF-C, -E, -H, -I, -P. Furthermore, the relation with the presence of perinuclear anti-neutrophil cytoplasmic autoantibodies (P-ANCA) was studied. A small, but statistically significant, association between the polymorphism at position -308 in the promoter region of the TNF-alpha gene and UC was found. The frequency of the uncommon TNF-alpha -308 allele 2 was found to be decreased in patients with UC compared with HC (allele frequency of allele 2 in UC patients 0-15 versus 0.25 in HC, P=0.044). No significant differences in distribution of the TNF haplotypes were found between IBD patients and HC, although there was a tendency towards a higher frequency of the TNF-C haplotype in UC patients compared with controls (haplotype frequency 22% versus 13%; P=0.19). No statistically significant differences in distribution of the TNF haplotypes were observed between P-ANCA-positive and P-ANCA-negative UC patients. The strength of the associations indicates that TNF genes are not markers for the predisposition to suffer from IBD. They may, however, be markers of subsets of patients with UC and CD.

Abstract
Besides a genetic predisposition, a causal role of various environmental factors have been taken into consideration in the etiology of inflammatory bowel disease (IBD). The most consistent association of environmental factors so far identified is the association between non smoking and ulcerative colitis (UC) as well a between smoking and Crohn's disease (CD). Other factors such as oral contraceptives, refined sugar, perinatal events, childhood infections, microbial agents, and domestic hygiene have been found to be associated with ulcerative colitis and Crohn's disease but further evaluation is required to confirm the consistency and to define the strength of the association. Recent data also suggest that measles virus may persist in intestinal tissue and early exposure to the virus may be a risk factor for development of CD. The further investigation of environmental factors on IBD and the explanation of their role is expected to open new avenues for basic scientific research and may lead to the development of a more rational approach to the prevention and treatment of IBD. The available data suggest that UC and CD are heterogeneous disorders of multifactorial etiology in which hereditary and environmental factors interact to produce the disease.

Abstract
OBJECTIVE To investigate a polymorphism within intron 2 of the interleukin-1 receptor antagonist (IL-1ra) gene in a Dutch white population of patients with ulcerative colitis and Crohn's disease. DESIGN Genotype and allele frequencies of the polymorphic region in the IL-1ra gene were determined in 111 unrelated patients with ulcerative colitis, 92 patients with Crohn's disease, and 86 healthy controls. METHODS The polymorphic region on the IL-1ra gene was amplified by the polymerase chain reaction (PCR). The resultant products were analyzed by electrophoresis on 2% agarose gels and stained with ethidium bromide. Amplification of the second exon of HLA-DRB1, HLA-DQA1, and HLA-DQB1 genes was performed by PCR, and Dot-blot analysis with biotin-labelled sequence-specific oligonucleotide probes was used for HLA typing. The standard perinuclear antineutrophil cytoplasmic antibodies (pANCA) indirect immunofluorescence assay was performed according to the protocol described by the First International Workshop on ANCA. RESULTS The frequency of allele 2 of the IL-1ra gene in ulcerative colitis (27.0%) and Crohn's disease patients (25.5%) did not differ significantly from healthy controls (23.8%). However, the estimate of the relative risk for carriers of allele 2 for ulcerative colitis [odds ratio (OR): 1.35, 95%-confidence interval (CI) from 0.73 to 2.49] was in agreement with a previous British study. The exact test for homogeneity of odds ratios provided no evidence for heterogeneity between both populations (P = 0.35) and therefore confirmed the genetic associated between ulcerative colitis and the IL-1ra allele 2 in a different population. Our data confirm that, in ulcerative colitis, the presence of this allele is a genetic marker for severity of the disease. A significant association was demonstrated between the carriership of allele 2 of the IL-1ra gene and the trend over the three localizations in ulcerative colitis (P = 0.023). The same approach for Crohn's disease when compared with healthy controls did not provide evidence for a similar association. The meta-analysis, based on the British data and our data, yielded: OR = 1.06, 95%-CI from 0.71 to 1.59, and P = 0.767. No association between IL-1ra gene polymorphism, and pANCA and the HLA-DR2 allele was found in ulcerative colitis.

Abstract
Recent reports have shown that allele 2 of the IL-1 receptor antagonist (IL-1Ra) gene is over-represented in ulcerative colitis (UC). Healthy individuals carrying allele 2 of this gene have increased production of IL-1Ra protein. Since the final outcome of the biological effects of IL-1 beta may depend on the relative proportion of these two cytokines, we have studied if a TaqI polymorphism in the IL-1 beta gene, which is relevant to IL-1 beta protein production, may be involved in the genetic susceptibility to UC and Crohn's disease (CD), in association with the established IL-1Ra gene polymorphism. Polymorphisms in the closely linked genes for IL-1 beta and IL-1Ra were typed in 100 unrelated Dutch patients with UC, 79 with CD, and 71 healthy controls. The polymorphic regions in exon 5 of the IL-1 beta gene and in intron 2 of the IL-1Ra gene, were studied by polymerase chain reaction (PCR)-based methods. The IL-1 beta allele frequencies in UC and CD patients did not differ from those in healthy controls. In order to study if the IL-1 beta gene polymorphism might participate synergistically with the IL-1Ra gene polymorphism in susceptibility to UC and CD, individuals were distributed into carriers and non-carriers of allele 2 of the genes encoding IL-1 beta and IL-1Ra, in each of the patient groups and controls. Results indicated a significant association of this pair of genes, estimated by the odds ratio (OR) after performing Fisher's exact test, in the UC group (P = 0.023, OR = 2.81), as well as in the CD group (P = 0.01, OR = 3.79). Thus, non-carriers of IL-1 beta allele 2 were more often present in the subgroup of patients carrying the IL-1Ra allele 2. By contrast, no association of these alleles was detected in the group of healthy controls (P = 1.00, OR = 0.92). These results suggest that the IL-1 beta/IL-1Ra allelic cluster may participate in defining the biological basis of predisposition to chronic inflammatory bowel diseases.
