RESUMO

AIM: The aim was to explore the subjective health expectations (sHE) of patients with Crohn's disease (CD) for both the near future and the elderly. METHOD: A cross-sectional survey was performed in four gastroenterology centres in Hungary. Consecutive outpatients with CD with age ≥ 18 were recruited. Socio-demographic and disease characteristics were recorded and the Crohn's Disease Activity Index (CDAI), Perianal Disease Activity Index, Patients' Global Assessment (PGA) and current pain visual analogue scale (VAS) were assessed. Subjective life expectancy (sLE) was explored and compared to statistical life expectancy. Current health and sHE for 1 year ahead and for ages 60/70/80/90 were assessed using the descriptive system of the EQ-5D-3L. RESULTS: In all, 206 patients (54.9% men) with a mean age of 34.7 (SD 10.5 years) and disease duration of 10.5 (SD 6.3) years were studied. The CDAI score was 110.5 (SD 77.0) and 66% were treated by biologic drugs. Mean current EQ-5D-3L score was 0.80 (SD 0.17) and patients expected a 0.05 (SD 0.15) improvement within a year (P < 0.05). For ages 60/70/80/90, a mean EQ-5D-3L score of 0.59, 0.38, 0.10 and -0.12 respectively was provisioned. Age, current health status, sLE, PGA and pain VAS showed significant correlation with both 1-year and older age sHE (P < 0.05). Long-term sHE and sLE were negatively affected by the presence of extraintestinal manifestations but not by previous CD-related surgery. CONCLUSION: Patients with CD expect severe deterioration in health in later life. Given that unrealistic sHE may affect patients' current quality of life and health behaviour, we encourage physicians to explore and consider CD patients' sHE in clinical care.

RESUMO

OBJECTIVES: The Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) program was initiated by the International Organization for the Study of Inflammatory Bowel Diseases (IOIBD). It examined potential treatment targets for inflammatory bowel disease (IBD) to be used for a "treat-to-target" clinical management strategy using an evidence-based expert consensus process. METHODS: A Steering Committee of 28 IBD specialists developed recommendations based on a systematic literature review and expert opinion. Consensus was gained if ≥75% of participants scored the recommendation as 7-10 on a 10-point rating scale (where 10=agree completely). RESULTS: The group agreed upon 12 recommendations for ulcerative colitis (UC) and Crohn's disease (CD). The agreed target for UC was clinical/patient-reported outcome (PRO) remission (defined as resolution of rectal bleeding and diarrhea/altered bowel habit) and endoscopic remission (defined as a Mayo endoscopic subscore of 0-1). Histological remission was considered as an adjunctive goal. Clinical/PRO remission was also agreed upon as a target for CD and defined as resolution of abdominal pain and diarrhea/altered bowel habit; and endoscopic remission, defined as resolution of ulceration at ileocolonoscopy, or resolution of findings of inflammation on cross-sectional imaging in patients who cannot be adequately assessed with ileocolonoscopy. Biomarker remission (normal C-reactive protein (CRP) and calprotectin) was considered as an adjunctive target. CONCLUSIONS: Evidence- and consensus-based recommendations for selecting the goals for treat-to-target strategies in patients with IBD are made available. Prospective studies are needed to determine how these targets will change disease course and patients' quality of life.

RESUMO

BACKGROUND: Data suggests that tight objective monitoring may improve clinical outcomes in IBD. AIM: To assess the adherence to serial tight objective monitoring(clinical and biomarkers) and its effect on clinical outcomes. METHODS: We retrospectively reviewed the chart of 428 consecutive IBD patients started on adalimumab between January 1,2015-January 1,2019 [338 Crohn's disease(CD), 90 ulcerative colitis(UC)]. Clinical symptoms(assessed by Harvey-Bradshaw-Index,partial Mayo),C-Reactive Protein(CRP), and fecal calprotectin(FCAL) assessments were captured at treatment initiation and at 3,6,9, and12 months. Dose optimization and drug sustainability curves were plotted by Kaplan-Meier method. RESULTS: Clinical evaluation was available in nearly all patients at 3(CD-UC:95-94%), 6(90-83%), 9(86-85%) and 12(96-89%) months. CRP testing frequency decreased in CD patients over time. Compliance to serial FCAL testing was low. Clinical remission at one-year was higher in patients adherent to early assessment visit at 3 months(p = 0.001 for CD and UC). Adherence to early follow-up resulted in earlier dose optimization in CD and UC patients(pLogrank=0.026 for UC & p = 0.09 for CD). Overall drug sustainability did not differ. CONCLUSION: Clinical & CRP, but not FCAL, were frequently assessed in patients starting adalimumab. Adherence to early objective combined follow-up visits resulted in earlier dose optimization, improved one-year clinical outcomes but did not change drug sustainability.

RESUMO

Genetic predisposition is a risk factor for the development of inflammatory bowel diseases (IBDs). Disruption of the interleukin (IL)-10 pathway in mice causes intestinal inflammation similar to human IBD. Two common non-synonymous IL-10R1 variants, S138G and G330R, were cloned and expressed in HeLa and Ba/F3. A reduction in IL-10-induced STAT1 and STAT3 activation was seen for IL-10R1-S138G (but not IL-10R1-G330R) by phosphospecific western blotting in both cell types. When analyzing 52 world populations for the presence of IL-10R1 variants, a strong dissimilarity was found between major geographical regions. In addition, when 182 IBD-parent trios were genotyped for both variants, a reduced transmission of haplotype -7 (carrying the S138G variant allele) to offspring with ulcerative colitis (UC) was observed. This UC-protective effect of S138G was confirmed in a Hungarian cohort (n=185, allele frequency 11.6 versus 17.5%; P=0.017) but not in an independent Belgian cohort (n=666, allele frequency 15.9 versus 15.5%; P=0.8). In conclusion, the IL-10R1 S138G variant is a loss-of-function allele for IL-10-induced STAT1 and STAT3 activation but does not protect from UC susceptibility.

RESUMO

BACKGROUND: DLG5 p.R30Q has been reported to be associated with Crohn disease (CD), but this association has not been replicated in most studies. A recent analysis of gender-stratified data from two case-control studies and two population cohorts found an association of DLG5 30Q with increased risk of CD in men but not in women and found differences between 30Q population frequencies for males and females. Male-female differences in population allele frequencies and male-specific risk could explain the difficulty in replicating the association with CD. METHODS: DLG5 R30Q genotype data were collected for patients with CD and controls from 11 studies that did not include gender-stratified allele counts in their published reports and tested for male-female frequency differences in controls and for case-control frequency differences in men and in women. RESULTS: The data showed no male-female allele frequency differences in controls. An exact conditional test gave marginal evidence that 30Q is associated with decreased risk of CD in women (p = 0.049, OR = 0.87, 95% CI 0.77 to 1.00). There was also a trend towards reduced 30Q frequencies in male patients with CD compared with male controls, but this was not significant at the 0.05 level (p = 0.058, OR = 0.87, 95% CI 0.74 to 1.01). When data from this study were combined with previously published, gender-stratified data, the 30Q allele was found to be associated with decreased risk of CD in women (p = 0.010, OR = 0.86, 95% CI 0.76 to 0.97), but not in men. CONCLUSION: DLG5 30Q is associated with a small reduction in risk of CD in women.

RESUMO

AIM: To test the cross-immunogenicity of anti-CT-P13 IBD patients' sera to CT-P13/infliximab originator and the comparative antigenicity evoked by CT-P13/infliximab originator sera. METHODS: Sera of patients with IBD with measurable anti-CT-P13 antibodies were tested for their cross-reactivity to 5 batches of infliximab originator and CT-P13. Anti-drug antibody positive sera from treated patients were used to compare antigenic epitopes. RESULTS: All 42 anti-CT-P13 and 37 anti-infliximab originator IBD sera were cross-reactive with infliximab originator and CT-P13 respectively. Concentration of anti-drug antibodies against infliximab originator or CT-P13 were strongly correlated both for IgG1 and IgG4 (P < 0.001). Anti-CT-P13 sera of patients with IBD (n = 32) exerted similar functional inhibition on CT-P13 or infliximab originator TNF binding capacity and showed reduced binding to CT-P13 in the presence of five different batches of CT-P13 and infliximab originator. Anti-CT-P13 and anti-infliximab originator IBD sera selectively enriched phage-peptides from the VH (CDR1 and CDR3) and VL domains (CDR2 and CDR3) of infliximab. Sera reactivity detected major infliximab epitopes in these regions of infliximab in 60%-79% of patients, and no significant differences were identified between CT-P13 and infliximab originator immunogenic sera. Minor epitopes were localised in framework regions of infliximab with reduced antibody reactivity shown, in 30%-50% of patients. Monoclonal antibodies derived from naïve individuals and ADA-positive IBD patients treated with CT-P13 provided comparable epitope specificity to five different batches of CT-P13 and infliximab originator. CONCLUSIONS: These results strongly support a similar antigenic profile for infliximab originator and CT-P13, and point toward a safe switching between the two drugs in anti-drug antibody negative patients.

RESUMO

BACKGROUND: NOD1/CARD4, a member of the pattern-recognition receptor family, is a perfect candidate as a susceptibility gene for Crohn's disease. Since only limited and conflicting data are available on G796A polymorphisms in inflammatory bowel disease patients, we set out to study the effect of this polymorphism on the susceptibility and course of Crohn's disease in the Hungarian population. METHODS: Four hundred thirty-four unrelated Crohn's disease patients (age at presentation: 28.6+/-9.6 years, female/male: 210/224, duration of Crohn's disease: 8.2+/-6.9 years) and 200 healthy subjects (blood donors) and 136 non-inflammatory bowel disease gastrointestinal controls with chronic gastritis were investigated. NOD1 G796A was detected by using polymerase chain reaction/restriction fragment length polymorphism. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: The frequencies of the variant alleles of NOD1 G796A differed significantly between the Crohn's disease patients and both healthy (GG 49.5% vs. 67%; AG 41.5% vs. 28%; and AA 9.0% vs. 5.2%; p<0.0001) and non-inflammatory bowel disease controls with chronic gastritis. Carriage of the single nucleotide polymorphism of NOD1 G796A proved to be a highly significant risk factor for Crohn's disease compared to both healthy (p<0.0001, OR: 2.1, 95% CI: 1.5-2.9) and non-inflammatory bowel disease controls with chronic gastritis (p=0.008). Significant associations were not found between the different genotypes and the demographic data on the patients or the clinical characteristics of Crohn's disease. The different polymorphisms of pattern-recognition receptors (e.g. NOD2/CARD15 SNP8, SNP12 and SNP13 mutations, the TLR4 D299G polymorphism and NOD1 G796A) did not reveal a mutual basis. CONCLUSIONS: Our results suggest that carriage of the NOD1 G796A mutation increases susceptibility for Crohn's disease in the Hungarian population.

RESUMO

Limited data are available on the management of inflammatory bowel diseases (IBD) in East European countries. The diagnostic tools and most treatment options are also available in Eastern Europe. The diagnostic procedures commonly used became more sophisticated in the past few years, with a greater use of computed tomography/magnetic resonance imaging and serology testing; however, double contrast barium enema, enteroclysis, and endoscopy remained standard. The medical therapy and surgical strategies are also somewhat different from those applied in Western countries. In ulcerative colitis, besides mesalazine, the use of sulphasalazine is still frequent, while azathioprine is only used in a minority of patients. The use of conventional corticosteroids is common and the rate of non-colorectal cancer associated colectomies is low. In contrast, 5-aminosalicylates are still used for maintenance in Crohn's disease and azathioprine is generally less frequently given compared with Western Europe. Biological agents have also become available about five years ago, yet their use is restricted mainly to specialised centres.

RESUMO

Limited data are available on the frequency of inflammatory bowel diseases in East European countries. A recent study from Hungary reported an increasing incidence rate for ulcerative colitis (from 1.6 to 11.0) and for Crohn's disease (from 0.4 to 4.7) from 1977 to 2001. A similar trend was seen in Croatia. In contrast, other countries (for example, Czech Republic, Poland, Romania, Slovakia, and Baltic countries) reported low incidence and prevalence rates. This review will discuss the available data on the epidemiology of inflammatory bowel diseases in Eastern Europe, as well as consider the possible factors responsible for the differences seen between countries and epidemiological trends.

RESUMO

BACKGROUND: A better knowledge of the natural history of disabling chronic diseases is essential to improve patient management, evaluate the impact of treatment strategies and provide predictors for disabling disease and comprehensive information for patients. AIM: To summarise our current knowledge issued from population-based studies of the natural history of ulcerative colitis (UC) in children. METHODS: We searched MEDLINE (source PubMed) and international conference abstracts, and included all population-based studies that evaluated long-term outcome of paediatric-onset (<17 years at diagnosis) UC. RESULTS: A total of 26 population-based studies were considered in this review from the total of 61 articles or abstracts screened. Most patients presented disease extension and about two-thirds of patients had pancolitis at the end of follow-up. One-half of patients experienced extra-intestinal manifestations and primary sclerosing cholangitis was observed in 5-10% of patients. Overall, patients did not appear to have any significant growth retardation or delayed puberty. About two-thirds of patients required corticosteroid therapy and up to 25% were steroid dependent. An increased use of thiopurines was observed and the most recent data indicate that up to one-half of patients were exposed to thiopurines and 10-30% were exposed to anti-tumour necrosis factor. One-half of patients required hospitalisations and 20% of patients required colectomy after a follow-up of 10 years. CONCLUSIONS: Paediatric-onset UC is characterised by a high rate of disease extension. About 20% of patients had been operated at 10-year follow-up. New population-based studies are needed to evaluate the impact of new treatment strategies comprising immunosuppressants and biologics.

RESUMO

BACKGROUND AND AIMS: The ECCO-EpiCom study investigates the differences in the incidence and therapeutic management of inflammatory bowel diseases [IBD] between Eastern and Western Europe. The aim of this study was to analyse the differences in the disease phenotype, medical therapy, surgery, and hospitalization rates in the ECCO-EpiCom 2011 inception cohort during the first year after diagnosis. METHODS: Nine Western, five Eastern European centres and one Australian centre with 258 Crohn's disease [CD], 380 ulcerative colitis [UC] and 71 IBD unclassified [IBDU] patients [female/male: 326/383; mean age at diagnosis: 40.9 years, SD: 17.3 years] participated. Patients' data were registered and entered in the web-based ECCO-EpiCom database [www.epicom-ecco.eu]. RESULTS: In CD, 36 [19%] Western Europe/Australian and 6 [9%] Eastern European patients received biological therapy [p = 0.04], but the immunosuppressive [IS] use was equal and high in these regions [Eastern Europe vs Western Europe/Australia: 53% vs 45%; p = 0.27]. Surgery was performed in 17 [24%] CD patients in Eastern Europe and 13 [7%] in Western Europe/Australia [p < 0.001, pLogRank = 0.001]. Of CD patients from Eastern Europe, 24 [34%] were hospitalized, and 39 [21%] from Western Europe/Australia, [p = 0.02, pLogRank = 0.01]. In UC, exposure to biologicals and colectomy rates were low and hospitalization rates did not differ between these regions during the 1-year follow-up period [16% vs 16%; p = 0.93]. CONCLUSIONS: During the first year after diagnosis, surgery and hospitalization rates were significantly higher in CD patients in Eastern Europe compared with Western Europe/Australia, whereas significantly more CD patients were treated with biologicals in the Western Europe/Australian centres.

RESUMO

Osteopathia has been reported in Wilson disease (WD), but bone density has not been measured; therefore, we performed bone mineral density (BMD), bone mineral content (BMC), and quantitative bone ultrasound (QUS) assessments, as well as measured the serum levels of osteocalcin (OCN), beta-cross-laps (beta-CTx's), and the recently discovered osteoprotegerin (OPG) and its ligand RANKL to investigate the underlying mechanism of osseous disorders. Serum OCN, beta-CTx, OPG, and RANKL levels were measured by ELISA in 21 WD patients and in 20 age- and gender-matched healthy subjects. BMD, BMC, and QUS parameters were also determined. Osteoporosis was present in 9/21 (43%) WD patients. Abnormal QUS parameters were found in 7 (33%) of the patients. Although serum OCN levels were similar in patients and controls (29.93 +/- 24.65 mg/ml vs. 29.84 +/- 6.89 mg/ml), beta-CTx and OPG levels were significantly increased in WD compared with the healthy controls (625.4 +/- 312.3 pg/ml vs. 423.6 +/- 144.3 pg/ml and p = 0.022 and 7.2 +/- 3.4 pM vs. 3.5 +/- 1.0 pM and p < 0.001, respectively). No difference was observed in the RANKL level. There was a positive correlation between OCN and beta-CTx (r = 0.55; p = 0.01). We proved high occurrence of osteoporosis in WD. Negative bone remodeling balance is a consequence of increased bone resorption, which is indicated by elevated beta-CTx. The novel finding of elevated serum OPG may reflect a compensatory reaction to enhanced osteoclast activity, despite the normal OCN level.

RESUMO

Although the incidence of gastric cancer has declined in the past few decades in developed countries, it has remained one of the most frequent malignomas with high mortality. Epidemiological, clinical and basic research studies confirm the role of Helicobacter pylori in the pathogenesis of the tumors of the distal stomach and low-grade MALT lymphomas. On the contrary more and more data suggest a possible protective role of the infection in the gastro-oesophageal reflux disease, tumors of the cardia and adenocarcinoma of the distal oesophagus. The intensive research being done in the past few years prove our previous concept, that the pathogenesis of gastric cancer is a multifactorial process, which is affected by Helicobacter pylori ("a major environmental factor") together with distinct environmental, social and genetic factors. The interaction of these factors and the importance of them urge further investigations, which may differ in different populations.

RESUMO

The (re)discovery of the gastric pathogen Helicobacter pylori almost one and a half decade ago completely changed our conception on gastroduodenal ulcer disease and gastric cancer. The most important issue is that Helicobacter pylori induces a mild, antrum dominant chronic pangastritis without increased risk of severe diseases in most of the cases. A smaller part of the infected develops antrum dominant gastritis with increased risk of duodenal ulcer. In a few cases the corpus is also affected, pangastritis occurs with increased risk to develop gastric ulcer and gastric cancer. Until now it is not quite obvious why some of the infected patients get ill while others not, and why different diseases develop in different patients. 1. From the bacterial point of view it is ascertained that toxin-producing strains (VacA, CagA positive) are more likely to induce ulcer formation and gastric carcinoma. 2. Genetic phenotype of the infected patients (blood-group and HLA antigens) may also be of importance. 3. Environmental factors may affect (promote or inhibit) disease development. All of these factors determine the complex immunological, functional and morphological changes characteristic for the developing disease.

RESUMO

Osteopenia is a common complication in primary biliary cirrhosis (PBC). In this follow-up study the authors investigated the metabolic bone disease in postmenopausal PBC patients. 17 Ca and vitamin D supplemented, postmenopausal female patients with PBC (stage II-IV, age: 41-84, mean: 52, each AMA M2 positive, without ascites) were followed-up for an average of 6.3 years. Bone mineral density (BMD) was measured yearly by dual energy x-ray absorptiometry (XR26, Norland) in lumbar spine (L2-4), femoral neck (FN), and radius BMC by single photon absorptiometry. Urinary pyridinoline/creatinine (Pyr/c) and deoxypyridinoline/creatinine ratio (D-Pyr/c) by HPLC, 25-OH-D3 level and standard liver function tests were monitored in all patients. At the beginning the BMD was decreased in 7 out of 17 patients (T-score < -2.5). The mean BMD was 0.885 SD +/- 0.26 g/cm2 in L2-4, 0.725 +/- 0.16 g/cm2 in FN and the BMC 0.703 +/- 0.14 g/cm in the radius. During follow-up the rate of annual bone loss was increased in patients with osteoporosis at the start of this study. There was a correlation between the urinary Pyr/c and D-pyr/c values and the annual rate of bone loss in patients with PBC (r: -0.79; p < 0.01). In patients with severe osteoporosis at the time of the diagnosis of PBC a more pronounced progression of bone loss was observed during the follow-up period.

RESUMO

There has been a major improvement in our knowledge in the area of molecular genetics in the past 20 years. It has become evident that genetic factors are important in the initiation, progression and prognosis of most diseases. Many studies addressed the issue of tumorigenesis, which provided insight into the molecular basis of the sequencional development of cancer, driven by the accumulation of genomic defects. Most of the neoplasms are genetically heterogeneous, independent pathways and simultaneous tumorigenesis may exist within the same organ. As some mutations exist in benignant and also in malignant conditions, it is an important challenge to define the molecular characteristics of significant versus non-significant lesions. A new form of therapeutic intervention is gene therapy. During the next decade it will likely play an increasing role in clinical practice and particularly in the treatment of cancer.

RESUMO

BACKGROUND AND AIMS: The aim of the present study was to validate the IBD (inflammatory bowel diseases) incidence reported in the 2010 ECCO-EpiCom (European Crohn's and Colitis Organization-Epidemiological Committee) inception cohort by including a second independent inception cohort from participating centers in 2011 and an Australian center to investigate whether there is a difference in the incidence of IBD between Eastern and Western European countries and Australia. METHODS: Fourteen centers from 5 Eastern and 9 Western European countries and one center from Australia participated in the ECCO-EpiCom 2011 inception cohort. Patients' data regarding disease type, socio-demographic factors, extraintestinal manifestations and therapy were entered into the Web-based EpiCom database, www.ecco-epicom.eu. RESULTS: A total of 711 adult patients were diagnosed during the inclusion year 2011, 178 (25%) from Eastern, 461 (65%) from Western Europe and 72 (10%) from Australia; 259 (37%) patients were diagnosed with Crohn's disease, 380 (53%) with ulcerative colitis and 72 (10%) with IBD unclassified. The mean annual incidence rate for IBD was 11.3/100,000 in Eastern Europe, 14.0/100,000 in Western Europe and 30.3/100,000 in Australia. Significantly more patients were diagnosed with complicated disease at diagnosis in Eastern Europe compared to Western Europe (43% vs. 27%, p=0.02). CONCLUSION: Incidence rates, disease phenotype and initial treatment characteristics in the 2011 ECCO-EpiCom cohort were not significantly different from that reported in the 2010 cohort.

RESUMO

BACKGROUND AND AIMS: The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe possibly due to changes in environmental factors towards a more "westernised" standard of living. The aim of this study was to investigate differences in exposure to environmental factors prior to diagnosis in Eastern and Western European IBD patients. METHODS: The EpiCom cohort is a population-based, prospective inception cohort of 1560 unselected IBD patients from 31 European countries covering a background population of 10.1 million. At the time of diagnosis patients were asked to complete an 87-item questionnaire concerning environmental factors. RESULTS: A total of 1182 patients (76%) answered the questionnaire, 444 (38%) had Crohn's disease (CD), 627 (53%) ulcerative colitis (UC), and 111 (9%) IBD unclassified. No geographic differences regarding smoking status, caffeine intake, use of oral contraceptives, or number of first-degree relatives with IBD were found. Sugar intake was higher in CD and UC patients from Eastern Europe than in Western Europe while fibre intake was lower (p<0.01). Daily consumption of fast food as well as appendectomy before the age of 20 was more frequent in Eastern European than in Western European UC patients (p<0.01). Eastern European CD and UC patients had received more vaccinations and experienced fewer childhood infections than Western European patients (p<0.01). CONCLUSIONS: In this European population-based inception cohort of unselected IBD patients, Eastern and Western European patients differed in environmental factors prior to diagnosis. Eastern European patients exhibited higher occurrences of suspected risk factors for IBD included in the Western lifestyle.

RESUMO

BACKGROUND AND AIMS: The EpiCom study and inception cohort was initiated in 2010 in 31 centers from 14 Western and 8 Eastern European countries, covering a 10.1million person background population. Our aim was to investigate whether there is a difference between Eastern and Western Europe in health care and education of patients with inflammatory bowel disease (IBD). METHODS: A quality of care (QoC) questionnaire was developed in the EpiCom group consisting of 16 questions covering 5 items: time interval between the onset of symptoms and diagnosis, information, education, empathy and access to health care providers. RESULTS: Of 1,515 patients, 947 (217 east/730 west) answered the QoC questionnaire. Only 23% of all patients had knowledge about IBD before diagnosis. In Eastern Europe, significantly more patients searched out information about IBD themselves (77% vs. 68%, p<0.05), the main source was the Internet (92% vs. 88% p=0.23). In Western Europe, significantly more patients were educated by nurses (19% vs. 1%, p<0.05), while in Eastern Europe, gastroenterologists were easier to contact (80% vs. 68%, p<0.05). CONCLUSION: Health care differed significantly between Eastern and Western Europe in all items, but satisfaction rates were high in both geographic regions. Because of the low awareness and the rising incidence of IBD, general information should be the focus of patient organizations and medical societies. In Western Europe IBD nurses play a very important role in reducing the burden of patient management.
