RESUMO

OBJECTIVE: The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East-West gradient in the incidence of IBD in Europe exists. DESIGN: A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience. RESULTS: 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100,000 in 2010 for CD were 6.5 (range 0-10.7) in Western European centres and 3.1 (range 0.4-11.5) in Eastern European centres, for UC 10.8 (range 2.9-31.5) and 4.1 (range 2.4-10.3), respectively, and for IBDU 1.9 (range 0-39.4) and 0 (range 0-1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy. CONCLUSIONS: An East-West gradient in IBD incidence exists in Europe. Among this inception cohort--including indolent and aggressive cases--international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

RESUMO

Resistin is a cysteine-rich protein, which is abundantly expressed at the site of inflammation, and acts as a regulator of the NF-kB-dependent cytokine cascade. The aim of this study was to evaluate resistin levels in relation to inflammatory mediators, disease phenotype and autoantibody status in a spectrum of pathological conditions of the gastrointestinal tract. Resistin levels were measured with an ELISA in sera originated from 227 patients and 40 healthy controls (HC). Fifty patients diagnosed with non-alcoholic fatty liver disease (NAFLD), 53 ulcerative colitis (UC), 51 Crohn's disease (CD), 46 autoimmune hepatitis (AIH) and 27 primary sclerosing cholangitis (PSC) were included. The sera were analysed with respect to biochemical parameters of systemic inflammation and liver function and to the presence of antibodies to nuclear antigens (ANA), mitochondria (AMA) and smooth muscle (SMA). Compared with HC, resistin levels were raised in AIH (P = 0.017) and PSC (P = 0.03); compared with NAFLD, levels were elevated in CD (P = 0.041), AIH (P < 0.001) and PSC (P < 0.001). Patients with elevated levels of resistin were more often treated with corticosteroids, but no difference was found between active disease and clinical remission. Resistin levels were significantly higher in ANA-positive individuals compared with ANA-negative (P = 0.025). Resistin levels were directly correlated with IL-6 (r = 0.30, P = 0.02) and IL-8 (r = 0.51, P < 0.001). Elevated levels of resistin were prominent in patients with hepatobiliary inflammation and were associated with breach of self-tolerance, i.e. ANA positivity. Thus, we propose that resistin may be an important marker of disease severity in autoantibody-mediated gastrointestinal inflammatory diseases.

RESUMO

OBJECTIVES: Inflammatory bowel disease (IBD), e.g., Crohn's disease (CD) and ulcerative colitis (UC), is a complex genetic disorder. Tumor necrosis factor (ligand) superfamily, member 15 (TNFSF15) has been previously identified as a susceptibility gene for CD in Japanese and UK cohorts. This replication study was designed in order to confirm and further validate the role of TNFSF15 in IBD. METHODS: A total of 666 IBD families (corresponding to 2,982 relatives) with European ancestry were genotyped for the rs6478108 and rs7869487 polymorphisms, which define the main TNFSF15 haplotypes previously associated with CD. An association between the main haplotypes and CD, UC and IBD was tested using the Genehunter TDT and Unphased statistics. Caspase recruitment domain 15 (CARD15)/TNFSF15 interaction and genotype/phenotype correlations were also studied. RESULTS: The previously reported "high-risk" haplotype (A) was associated with IBD (P=0.001) (OR=1.25 (1.05-1.50)) and CD (P=0.02) (OR=1.31 (1.03-1.67)) whereas the "protective" (B) haplotype was significantly less transmitted to IBD and CD patients. No interaction between CARD15 and TNFSF15 was detected. We also failed to define a clinical subgroup of CD patients specifically associated with TNFSF15 haplotype A. CONCLUSIONS: This study confirms that TNFSF15 or a closely linked gene is involved in the genetic predisposition to CD.

RESUMO

BACKGROUND: Firm recommendations about the way thiopurine drugs are introduced and the use of thiopurine methyltransferase (TPMT) and metabolite measurements during treatment in inflammatory bowel disease (IBD) are lacking. AIM: To evaluate pharmacokinetics and tolerance after initiation of thiopurine treatment with a fixed dosing schedule in patients with IBD. PATIENTS: 60 consecutive patients with Crohn's disease (n = 33) or ulcerative colitis (n = 27) were included in a 20 week open, prospective study. METHODS: Thiopurine treatment was introduced using a predefined dose escalation schedule, reaching a daily target dose at week 3 of 2.5 mg azathioprine or 1.25 mg 6-mercaptopurine per kg body weight. TPMT and ITPA genotypes, TPMT activity, TPMT gene expression, and thiopurine metabolites were determined. Clinical outcome and occurrence of adverse events were monitored. RESULTS: 27 patients completed the study per protocol, while 33 were withdrawn (early protocol violation (n = 5), TPMT deficiency (n = 1), thiopurine related adverse events (n = 27)); 67% of patients with adverse events tolerated long term treatment on a lower dose (median 1.32 mg azathioprine/kg body weight). TPMT activity did not change during the 20 week course of the study but a significant decrease in TPMT gene expression was found (TPMT/huCYC ratio; p = 0.02). Patients with meTIMP concentrations >11,450 pmol/8 x 10(8) red blood cells during steady state at week 5 had an increased risk of developing myelotoxicity (odds ratio = 45.0; p = 0.015). CONCLUSIONS: After initiation of thiopurine treatment using a fixed dosing schedule, no general induction of TPMT enzyme activity occurred, though TPMT gene expression decreased. The development of different types of toxicity was unpredictable, but we found that measurement of meTIMP early in the steady state phase helped to identify patients at risk of developing myelotoxicity.

RESUMO

BACKGROUND: Real-life long-term data on infliximab treatment in ulcerative colitis are limited. AIM: To study the long-term efficacy and safety of infliximab in chronic active ulcerative colitis and possible predictors of colectomy and response were also examined. METHODS: A retrospective multi-centre study of infliximab treatment in 250 patients with chronic active ulcerative colitis with inclusion criteria: age ≥18 years, ambulatory treated, steroid-dependent or intolerant and/or immunomodulator refractory or intolerant. RESULTS: Steroid-free clinical remission was achieved by 123/250 patients (49.2%) at 12 months and in 126/250 patients at a median follow-up of 2.9 years (50.4%). Primary response at 3 months was achieved by 190/250 (76.0%) patients and associated with a high probability of response 168/190 (88.4%) at 12 months and 143/190 (75.3%) at follow-up. Long-term rate of colectomy in primary responders was 6/190 (3.2%) at 12 months and 27/190 (14.2%) at last follow-up. Failure to achieve response at 3 months was associated with a high risk of subsequent colectomy, 29/60 (48.3%) at 12 months and 41/60 (68.3%) at follow-up. Response at 12 months was associated with a low risk of subsequent colectomy, 14/181 (7.7%) compared with non-response 19/34 (55.9%) (P < 0.0001). Non-response at 3 months was an independent predictor of subsequent colectomy (HR = 9.40, 95% CI = 5.10-17.35, P < 0.001). Concomitant azathioprine therapy did not influence outcome in terms of colectomy. CONCLUSIONS: Long-term efficacy of infliximab treatment in chronic active ulcerative colitis is excellent especially in patients who respond to induction treatment. Conversely, non-response at 3 months predicts a poor outcome, with a high risk of subsequent colectomy.

RESUMO

BACKGROUND: Adverse events leading to discontinuation or dose reduction of thiopurine therapy occur in 9-28% of patients with inflammatory bowel disease. AIMS: To evaluate the influence of thiopurine methyltransferase status and thiopurine metabolites in a large patient population for the risk of developing adverse event. METHODS: Three hundred and sixty-four patients with inflammatory bowel disease and present or previous thiopurine therapy were identified from a local database. RESULTS: The adverse event observed in 124 patients (34%) were more common in adults than children (40% vs. 15%; P < 0.001) and in low to intermediate (

RESUMO

The aim of this study was to follow, during standardized initiation of thiopurine treatment, thiopurine methyltransferase (TPMT) gene expression and enzyme activity and thiopurine metabolite concentrations, and to study the role of TPMT and ITPA 94C > A polymorphisms for the development of adverse drug reactions. Sixty patients with ulcerative colitis or Crohn's disease were included in this open and prospective multi-center study. Thiopurine naïve patients were prescribed azathioprine (AZA), patients previously intolerant to AZA received 6-mercaptopurine (6-MP). The patients followed a predetermined dose escalation schedule, reaching target dose at Week 3; 2.5 and 1.25 mg/kg body weight for AZA and 6-MP, respectively. The patients were followed every week during Weeks 1-8 from baseline and then every 4 weeks until 20 weeks. TPMT activity and thiopurine metabolites were determined in erythrocytes, TPMT and ITPA genotypes, and TPMT gene expression were determined in whole blood. One homozygous TPMT-deficient patient was excluded. Five non compliant patients were withdrawn during the first weeks. Twenty-seven patients completed the study per protocol; 27 patients were withdrawn because of adverse events. Sixty-seven percent of the withdrawn patients tolerated thiopurines at a lower dose at Week 20. There was no difference in baseline TPMT enzyme activity between individuals completing the study and those withdrawn for adverse events (p = 0.45). A significant decrease in TPMT gene expression (TPMT/huCYC ratio, p = 0.02) was found, however TPMT enzyme activity did not change. TPMT heterozygous individuals had a lower probability of remaining in the study on the predetermined dose (p = 0.039). The ITPA 94C > A polymorphism was not predictive of adverse events (p = 0.35).

RESUMO

Crohn's disease (CD) is a complex genetic disorder for which a susceptibility gene, IBD1, has been mapped within the pericentromeric region of chromosome 16. In order to refine the location of IBD1, 77 multiplex CD families were genotyped for 26 microsatellite markers evenly spaced by approximately 1 cM. Nonparametric linkage analyses exhibited a maximum NPL score of 3.49 (P=2.37x10(-4)) in a region centred by markers D16S3136, D16S3117 and D16S770. Simulation studies showed that the probability for IBD1 to be located in a 5 cM region around these markers was 70%. A 2.5 Mb YAC and BAC contig map spanning this genetic region on chromosome band 16q12 was built. TDT analyses demonstrated suggestive association between the 207 bp allele of D16S3136 (P<0.05) and a new biallellic marker hb27g11f-end (P=0.01). These markers were located in the hb27g11 and hb87b10 BAC clones from the contig. Taken together, the present results provide a crucial preliminary step before an exhaustive linkage disequilibrium mapping of putatively transcribed regions to identify IBD1.

RESUMO

Topically applied antifibrinolytic drugs may be of value in the control of bleeding in active ulcerative colitis. Any impairment of systemic fibrinolysis in this condition, however, is potentially harmful. Since pharmacokinetic data after the rectal administration of tranexamic acid are non-existent, plasma concentration and recovery in the urine were recorded after a single dose of 2 g tranexamic acid given rectally to five patients with ulcerative colitis and to five healthy volunteers. The median area under the curve was, for the volunteers, 7.64 mg/L x hr (range: 4.43-11.56) and, for the patients, 13.84 mg/L x hr (range: 9.32-50.22) (P less than .05). The median 24-hour recovery in the urine was 0.8% (0.3-1.1) and 2.7% (1.1-4.0), respectively (P less than .05). The median peak plasma concentration was, for the volunteers, 0.40 mg/L (range: 0.20-0.69) 6 hours after administration and, for the patients, 1.10 mg/L (range: 0.53-2.90) 5 hours after administration (P less than .05). The plasma concentrations and recovery in the urine that were observed in the patients and volunteers were low compared with those seen after oral intake of the same dose. The plasma concentrations did not reach levels that were considered liable to impair systemic fibrinolysis.

RESUMO

OBJECTIVE: Health is a complex and multi-dimensional entity and is neither easily determined nor easily conveyed to others. Publications have often combined various variables of disease activity and health-related quality of life (HRQoL), used the variables interchangeably or utilized summation indices to compare health assessment. The aim of this study is to investigate the relationship between measurements of disease activity and HRQoL. STUDY: design Cross-sectional evaluation of disease activity and HRQoL. STUDY POPULATION: Two hundred and eleven consecutive patients with ulcerative colitis. SETTING: The catchment area of Linköping University Hospital. MEASUREMENTS: HRQoL was measured using two questionnaires, the Sickness Impact Profile (SIP) and the Rating Form of IBD Patient Concerns (RFIPC). Patients were also asked if they were 'feeling fit and well', as a measurement of general health perception. Disease activity was measured by means of symptom cards, laboratory tests and sigmoidoscopy. RESULTS: The correlations (Spearman's r (r5)) between variables of disease activity and HRQoL were low. 'Feeling fit and well' was best correlated to worries and concerns (the RFIPC, rs 0.32, P < 0.05), while there was a decreasing association with subjective functional status (the SIP, rs 0.31, P < 0.05), symptoms (stools per day, rs 0.15, not significant) and biological variables (endoscopy score, rs 0.04, not significant). CONCLUSION: The correlations between traditional measurements of disease activity and various measures of HRQoL are low. We therefore propose a system whereby the process is conceptualized using a 'network strategy', ordering the measurements of disease activity and HRQoL into five dimensions: biological variables, symptoms, functional status, worries and concerns, and health perceptions. We feel that this method of interpretation more accurately reflects the overall health of a group of patients with IBD than more traditional summation indices.

RESUMO

OBJECTIVE: To compare air enema radiology with a leukocyte scintigraphy technique using technetium-99m-hexamethyl propylene amine oxime-labelled leukocytes for imaging colonic inflammation in ulcerative colitis. DESIGN: Prospective study in a University hospital. One radiologist and one nuclear physician independently graded the degree of inflammation in six colon segments per patient using radiographs and leukocyte scans. PATIENTS: Twenty consecutive patients with symptoms of active ulcerative colitis requiring corticosteroids, inflammation on rigid sigmoidoscopy and a positive leukocyte scan above the rectum. RESULTS: Using air enema radiology, inflammation above the rectum was observed in 17 of the 20 patients. Eleven patients had the same extent of disease with both imaging techniques (total n = 5; extensive n = 3; distal n = 3). Seven patients had more widespread colitis using leukocyte scintigraphy. In the remaining two patients with extensive inflammation at scintigraphy, air enema films showed total colitis. When the colon was subdivided into six different segments, prediction of the presence of inflammation in individual segments was 0.88 for air enema radiology compared with leukocyte scintigraphy and 0.60 for the prediction of absence of inflammation. All segments with an irregular mucosal contour or ulceration on air enema films had intense inflammation at scintigraphy. CONCLUSIONS: In patients with active ulcerative colitis, air enema radiology underestimates the extent of inflammation because this investigation shows secondary patho-anatomical changes, while leukocyte scintigraphy visualizes the acute cellular infiltrate. In patients with more severe inflammation, there is excellent agreement between the two methods.

RESUMO

In order to compare visual interpretation of inflammation detected by leukocyte scintigraphy with that of different computer-aided quantification methods, 34 patients (25 with ulcerative colitis and 9 with endoscopically verified non-inflamed colonic mucosa), were investigated using 99Tcm-hexamethylpropyleneamine oxime (99Tcm-HMPAO) leukocyte scintigraphy and colonoscopy with biopsies. Scintigrams were obtained 45 min and 4 h after the injection of labelled cells. Computer-generated grading of seven colon segments using four different methods was performed on each scintigram for each patient. The same segments were graded independently using a 4-point visual scale. Endoscopic and histological inflammation were scored on 4-point scales. At 45 min, a positive correlation was found between endoscopic and scan gradings in individual colon segments when using visual grading and three of the four computer-aided methods (Spearman's rs = 0.30-0.64, P < 0.001). Histological grading correlated with visual grading and with two of the four computer-aided methods at 45 min (rs = 0.42-0.54, P < 0.001). At 4 h, all grading methods correlated positively with both endoscopic and histological assessment. The correlation coefficients were, in all but one instance, highest for the visual grading. As an inter-observer comparison to assess agreement between the visual gradings of two nuclear physicians, 14 additional patients (9 ulcerative colitis, 5 infectious enterocolitis) underwent leukocyte scintigraphy. Agreement assessed using kappa statistics was 0.54 at 45 min (P < 0.001). Separate data concerning the presence/absence of active inflammation showed a high kappa value (0.74, P < 0.001). Our results showed that a simple scintigraphic scoring system based on assessment using the human eye reflects colonic inflammation at least as well as computer-aided grading, and that highly correlated results can be achieved between different investigators.

RESUMO

The inclusion of a patient's illness experience as outcome in the assessment of health care technology has revealed methodological limitations such as the interpretation of multi-attribute scores and lack of knowledge about the association between illness and disease information. In an attempt to overcome these limitations, a cross-sectional study is performed to search for patterns of illness severity and investigate the association between illness measures and between illness patterns and disease factors. A sample of 211 patients with ulcerative colitis is studied using the sickness impact profile (SIP) and the rating form for inflammatory bowel disease patient concerns (RFIPC) as illness measures. SIP and RFIPC scores show low association, suggesting that they provide complementary information about the patient's illness status. Cluster analysis is performed using the two measures of illness separately to identify groups of patients with different degrees of severity of illness (clusters). The cluster description covers illness, disease and social and demographic variables. The RFIPC clusters show a general pattern of ascendant rank scores for the RFIPC items. SIP clusters differ, not only in the level of severity, but also in specific types of disability. The patients in the clusters with the highest degree of disability (reflected by SIP) show a non-linear relationship with patients' concerns (reflected by RFIPC) and disease factors.

RESUMO

Retrograde colonic distribution of a new 4 g 5-aminosalicylic acid enema (mesalazine) was investigated in seven patients with ulcerative colitis, five of whom were in remission. The enema was labeled with 99m-technetium and imaged by a gamma camera. A median of 86 percent (range 57-90) of the enema had spread beyond the rectum during the first two hours after administration. In four of the five examined patients with left-sided ulcerative colitis, the diseased mucosa was covered within the first 4 hours. In the fifth patient, with involvement of the descending colon, the enema did not spread beyond the very tortuous sigmoid colon 4 or even 8 hours after enema administration.

RESUMO

In inflammatory bowel disease, the use of various diagnostic techniques to visualise the extent and severity of inflammation is of vital importance at the onset of disease, in the event of subsequent relapse, and when complications are suspected. Medical treatment and surgery can thus be optimised and limited operations performed, especially in Crohn's disease. The article consists in a summary of published reports from a single centre, representing 10 years' experience of three new techniques for assessing inflammatory bowel disease. Leucocyte scintigraphy is a non-invasive and well-tolerated method whereby the small and large bowels are assessed on the same occasion, and complications such as abscesses and possibly fistulas can be visualised. Intraoperative enteroscopy yields more accurate information than previous methods for deciding the extent of small bowel resections, and often permitting gut to be saved. Air enema radiography is a convenient and safe means of obtaining reliable information about the presence and depth of ulceration in ulcerative colitis. These methods facilitate the care of patients with inflammatory bowel disease, and should be made available at centres where such patients are treated.

RESUMO

Chronic inflammatory bowel diseases, ulcerative colitis and Crohn's disease, are steadily increasing in prevalence, and one half to one per cent of the Swedish population are currently estimated to be affected. The aetiology remains unknown, but is probably multifactorial. Both dietary, microbiological and immunological causes have been discussed. Clinical studies, including several Swedish studies, have also shown genetic factors to be crucially involved. Findings in sophisticated molecular biological studies suggest certain specific genes to be involved, and a current EU project in which Sweden is participating has been launched to map the mode of inheritance in detail.

RESUMO

Two cases of young patients with the chronic form of Budd-Chiari syndrome are reported. The first concerns a 22-year-old woman with a 6-month history of hepatomegaly, who had used oral contraceptives almost continuously during the five years preceding diagnosis. In a thorough diagnostic work-up, thromboses were detected in all but one of the hepatic veins, and a possible non-occluding thrombosis in the retrohepatic portion of the inferior vena cava. In the blood and bone marrow, findings were compatible with polycythaemia rubra vera, and a high anti-cardiolipin antibody titre was found. The second case concerns a 25-year-old male smoker with normal bone marrow, who had thromboses in at least two of the hepatic veins, though the inferior vena cava was not occluded. In both cases a mesocaval shunt was interposed with synthetic grafts, and postoperatively the patients are doing well--at sixteen and five months, respectively. Both are maintained on anticoagulants, and even without diuretics there has been no recurrence of ascites. The woman takes a small dose of hydroxy-urea to control her hypercoagulability. To our knowledge, hers is the first case to be reported of Budd-Chiari syndrome with hypercoagulability due to the concomitant presence of oral contraceptives, polycythaemia rubra vera and anti-phospholipid antibodies.


PIP: The Budd-Chiari syndrome is a rare condition (0.4-.06 per cent in autopsy material) characterized by ascites, liver function disturbance and abdominal pain caused by thrombosis of the major hepatic veins. $ studies (N = 114) yield the following list of causes with percentages; Oral contraceptives, 18%; polycythemia vera, 13%; other myelo-proliferative disease, 4%; paroxysmal nocturnal hemoglobinuria, 5%; blood vessel malformation, 10%; malignancy, 6%; other simultaneous thrombosis, 3%, vasculitis, 2%; other (trauma, abscess, chronic active hepatitis, pregnancy) 5%; no known cause, 34%. The histories of 2 patients illustrate the difficulty of diagnosis, which is usually verified only by biopsy. One of the patients was a 20-year old woman who had used oral contraceptives for 5 years and presented changes consistent with myeloproliferative syndrome in the peripheral circulation and in the bone marrow, as well as a high cardiolipin antibody titer. Oral contraceptives have been cited as a cause of Budd- Chiari syndrome, but the proportion of oral contraceptives users among patients is no greater than among women in general. One recent French study (N = 33) gives a relative risk factor of 2.4 for women between 15 and 45 years old who have used oral contraceptives during the 12 months before onset of the disease. This risk factor parallels that for stroke, myocardial infarction, and venous thromboembolism. No cases of Budd- Chiari syndrome had been reported to the Swedish side-effects register through December 1988.

RESUMO

BACKGROUND & AIMS: Health-related quality of life (HRQoL) is impaired in patients with Inflammatory Bowel Disease (IBD). The aim was prospectively to assess and validate the pattern of HRQoL in an unselected, population-based inception cohort of IBD patients from Eastern and Western Europe. METHODS: The EpiCom inception cohort consists of 1560 IBD patients from 31 European centres covering a background population of approximately 10.1 million. Patients answered the disease specific Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and generic Short Form 12 (SF-12) questionnaire at diagnosis and after one year of follow-up. RESULTS: In total, 1079 patients were included in this study. Crohn's disease (CD) patients mean SIBDQ scores improved from 45.3 to 55.3 in Eastern Europe and from 44.9 to 53.6 in Western Europe. SIBDQ scores for ulcerative colitis (UC) patients improved from 44.9 to 57.4 and from 48.8 to 55.7, respectively. UC patients needing surgery or biologicals had lower SIBDQ scores before and after compared to the rest, while biological therapy improved SIBDQ scores in CD. CD and UC patients in both regions improved all SF-12 scores. Only Eastern European UC patients achieved SF-12 summary scores equal to or above the normal population. CONCLUSION: Medical and surgical treatment improved HRQoL during the first year of disease. The majority of IBD patients in both Eastern and Western Europe reported a positive perception of disease-specific but not generic HRQoL. Biological therapy improved HRQoL in CD patients, while UC patients in need of surgery or biological therapy experienced lower perceptions of HRQoL than the rest.

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.
