Abstract
BACKGROUND AND AIMS Therapeutic drug monitoring of active metabolites of thiopurines, azathioprine and 6-mercaptopurine, is relatively new. The proposed therapeutic threshold level of the active 6-thioguanine nucleotides (6-TGN) is ≥235 pmol/8×10(8) erythrocytes. The aim of this prospective cross-sectional study was to compare 6-TGN levels in adult thiopurine tolerant IBD patients with an exacerbation with those in remission, and to determine the therapeutic 6-TGN cut-off level. METHODS Hundred IBD patients were included. Outcome measures were thiopurine metabolite levels, calculated therapeutic 6-TGN cut-off level, CDAI/CAI scores, thiopurine dose and TPMT enzyme activity. RESULTS Forty-one patients had an exacerbation, 59 patients were in remission. In 17% of all patients 6-TGN levels were compatible with non-compliance. The median 6-TGN levels were not significantly different between the exacerbation and remission group (227 versus 263 pmol/8×10(8) erythrocytes, p=0.29). The previous reported therapeutic 6-TGN cut-off level of 235 pmol/8×10(8) erythrocytes was confirmed in this study. Twenty-six of the 41 patients (63%) with active disease had 6-TGN levels below this threshold and 24 of 59 IBD patients (41%) in clinical remission (p=0.04). CONCLUSIONS Thiopurine non-compliance occurs frequently both in active and quiescent disease. 6-TGN levels below or above the therapeutic threshold are associated with a significant higher chance of IBD exacerbation and remission, respectively. These data support the role of therapeutic drug monitoring in thiopurine maintenance therapy in IBD to reveal non-compliance or underdosing, and can be used as a practical tool to optimize thiopurine therapy, especially in case of thiopurine non-response.

Abstract
BACKGROUND Participation in and tolerability of primary colonoscopy screening are presumed to be relatively low. The present study aimed to test its feasibility in a well-informed population of hospital staff using an intensive information campaign, and to identify factors associated with screening colonoscopy rated as uncomfortable. METHODS Data were collected using standardized forms. RESULTS Out of 1,090 invited employees (50-65 years), 447 (41.0%) participated. Bowel preparation and colonoscopy were rated as 'somewhat to very uncomfortable' by 79.5 and 21.9%, respectively. 96.3% of participants were willing to repeat colonoscopy in the future. Participants rating colonoscopy as uncomfortable were more likely unwilling to repeat the procedure (OR 8.026, CI 2.667-24.154). Multivariate analysis (age- and gender-adjusted) showed an association of colonoscopy rated as uncomfortable with: abdominal pain during colonoscopy (OR 3.185, CI 1.642-6.178), other pain (OR 2.428, CI 1.335-4.416), flatulence (OR 2.175, CI 1.219-3.881), embarrassment (OR 2.843, CI 1.350-5.989), abdominal pain after colonoscopy (OR 1.976, CI 1.041-3.751), and a prolonged procedure time (OR 1.000, CI 1.000-1.001). CONCLUSIONS Acceptance of primary colonoscopy screening for colorectal neoplasia was high, although participants with symptoms during and after colonoscopy were more likely to rate colonoscopy as uncomfortable. This type of opportunistic screening procedure is suitable for the introduction of screening programs and may be useful in areas that have no access to population-based screening.

Abstract
Given the current increase in colorectal cancer screening, information on performance of screening tests is needed, especially in groups with a presumed lower test performance. We compared test performance of immunologic fecal occult blood testing (FIT) and pseudosigmoidoscopy with colonoscopy for detection of advanced adenomas in an average risk screening population. In addition, we explored the influence of gender, age, and location on test performance. FIT was collected prior to colonoscopy with a 50 ng/mL cutoff point. FIT results and complete colonoscopy findings were available from 329 subjects (mean age: 54.6 ± 3.7 years, 58.4% women). Advanced adenomas were detected in 38 (11.6%) of 329 subjects. Sensitivity for advanced adenomas of FIT and sigmoidoscopy were 15.8% (95% CI: 6.0-31.3) and 73.7% (95% CI: 56.9-86.6), respectively. No sensitivity improvement was obtained using the combination of sigmoidoscopy and FIT. Mean fecal hemoglobin in FIT positives was significantly lower for participants with only proximal adenomas versus those with distal ones (P = 0.008), for women versus men (P = 0.023), and for younger (<55 years) versus older (≥55 years) subjects (P = 0.029). Sensitivities of FIT were 0.0% (95% CI: 0.0-30.9) in subjects with only proximal versus 21.4% (95% CI: 8.3-41.0) in those with distal nonadvanced adenomas; 5.3% (95% CI: 0.0-26.0) in women versus 26.3% (95% CI: 9.2-51.2) in men; 9.5% (95% CI: 1.2-30.4) in younger versus 23.5% (95% CI: 6.8-49.9) in older subjects. Sigmoidoscopy had a significantly higher sensitivity for advanced adenomas than FIT. A single FIT showed very low sensitivity, especially in subjects with only proximal nonadvanced adenomas, in women, and in younger subjects. This points to the existence of "low" FIT performance in subgroups and the need for more tailored screening strategies.

Abstract
BACKGROUND Large colorectal cancer screening studies using primary colonoscopy have reported a low risk of major complications. Studies on diagnostic and therapeutic colonoscopy have pointed to a frequent occurrence of(minor) cardiopulmonary events, and with the steady increase of colonoscopy screening, it is important to investigate their occurrence in colonoscopy screening. METHODS This study describes the frequency of bradycardia(pulse rate <60 min-1), hypotension (systolic blood pressure(SB P) <90 mmHg), hypoxaemia (blood oxygenation, SaO2<90%) and ECG changes during colonoscopy screening in an average-risk population (hospital personnel, n=214,mean age 54.0±3.8, 39.3% male), without significant comorbidity) and aims at identifying subject-related and/or endoscopic factors associated with their occurrence. All data were collected prospectively. During 214 consecutive primary screening colonoscopies under conscious sedation(midazolam and pethidine), on top of pulse rate and SaO2,blood pressure and a three-channel ECG were recorded every five minutes. RESULTS No major complications or relevant ECG changes occurred. Hypoxaemia occurred in 119 (55.6%),hypotension in 19 (8.9%) and bradycardia in 12 subjects(5.6%). In multivariate analysis, the sedation level 3 increased the risk of hypoxaemia (OR 4.8, CI 1.7-13.7), and incomplete colonoscopy (OR 5.3, CI 1.6-18.1) was associated with hypotension. Subjects with bradycardia had a longer mean procedure time (38±12 vs. 29±12 min, p<0.05), which did not turn out as a risk factor in a multivariate analysis. CONCLUSIONS Mainly procedure-related and not subject-related factors were found to be associated with the occurrence of cardiopulmonary events in primary colonoscopy screening in this relatively healthy screening population.

Abstract
BACKGROUND The importance of fatigue in chronic disease has been increasingly recognized; however, little is known about fatigue in inflammatory bowel disease (IBD). The aim of the present study was to investigate the prevalence and severity of fatigue and the impact on health-related quality of life (HRQoL) in patients included in a population-based IBD cohort in the Netherlands. METHODS IBD patients, diagnosed between January 1st, 1991, and January 1st, 2003, were followed up for a median of 7.1 years. They completed a questionnaire, which included a disease activity score, the Multidimensional Fatigue Inventory (MFI-20), the Inflammatory Bowel Disease Questionnaire (IBDQ), and the Short Form health survey (SF-36). Hemoglobin levels were recorded. RESULTS Data were available in 304 Crohn's disease (CD), 368 ulcerative colitis (UC), and 35 indeterminate colitis (IC) patients. During quiescent disease, the prevalence of fatigue was nearly 40%. MFI-20 and HRQoL scores were significantly worse in IBD patients having active disease. In a multivariate analysis, disease activity was positively related with the level of fatigue in both CD and UC. In UC, anemia influenced the general fatigue score independently of disease activity. Disease activity as well as fatigue were independently associated with an impaired IBDQ. CONCLUSIONS In IBD, even in remission, fatigue is an important feature. Both in CD and in UC, fatigue determined HRQoL independently of disease activity or anemia. This implies that in IBD patients physicians need to be aware of fatigue in order to better understand its impact and to improve the HRQoL.

Abstract
OBJECTIVE The European Panel on the Appropriateness of Crohn's disease Therapy (EPACT) has developed appropriateness criteria. We have applied these criteria retrospectively to the population-based inception cohort of Crohn's disease (CD) patients of the European Collaborative Study Group on Inflammatory Bowel Disease (EC-IBD). MATERIAL AND METHODS A total of 426 diagnosed CD patients from 13 European centers were enrolled at the time of diagnosis (first flare, naive patients). We used the EPACT definitions to identify 247 patients with active luminal CD. We then assessed the appropriateness of the initial drug prescription according to the EPACT criteria. RESULTS Among the cohort patients 163 suffered from mild-to-moderate CD and 84 from severe CD. Among the mild-to-moderate disease group, 96 patients (59%) received an appropriate treatment, whereas for 66 patients (40%) the treatment was uncertain and in one case (1%) inappropriate. Among the severe disease group, 86% were treated medically and 14% required surgery. 59 (70%) were appropriately treated, whereas for one patient (1%) the procedure was considered uncertain and for 24 patients (29%) inappropriate. CONCLUSION Initial treatment was appropriate in the majority of cases for non-complicated luminal CD. Inappropriate or uncertain treatment was given in a significant minority of patients, with an increased potential risk of adverse events.

Abstract
OBJECTIVE Although there is a suggestion that the medical psychiatric unit (MPU) may reduce length of hospital stay (LOS), little is known about costs in terms of medical service use and psychiatric interventions in MPU care. METHOD A record linkage study was conducted, linking cost data of hospital medical service use, LOS, and hospital psychiatric interventions to patients admitted to the MPU of the Maastricht University Medical Centre (MUMC) between 1998 and 2004. The data set was analyzed to enable comparison between cost changes of the same complex patient population following either MPU index admission or index admissions to reference MUMC medical wards. RESULTS Comparisons revealed lower costs of medical service use in favor of the MPU (-euro104; 95% CI -euro174 to -euro35; P<.01). However, cost of psychiatric intervention and cost of LOS were higher after MPU admission (respectively, +euro165; 95% CI +euro25 to +euro305; P<.05; and +euro202; 95% CI +euro170 to +euro235; P<.001). Total costs were higher after MPU admission compared to medical ward admission (+euro263; 95% CI +euro68 to +euro458; P<.05). These differences were not moderated by somatic diagnosis or previous pattern of admissions. CONCLUSION The findings suggest that patients at the interface of psychiatric and somatic morbidity are diagnosed and treated adequately at the MPU, leading to a decrease in medical service use and an appropriate increase in exposure to psychiatric interventions. These results are specifically generalizable to MPUs with a focus on psychosomatic conditions, for instance, somatoform disorders or affective disorders with comorbid somatic diseases. However, failure to show cost savings in terms of LOS compared to medical wards outweighs cost-benefit derived from lower medical service use, suggesting that MPU activities may gain in cost-effectiveness if shifted more to outpatient psychosomatic care solutions.

Abstract
We have used a gene expression array-based strategy to identify the methylation of tissue factor pathway inhibitor 2 (TFPI2), a potential tumor suppressor gene, as a frequent event in human colorectal cancers (CRC). TFPI2 belongs to the recently described group of embryonic cell Polycomb group (PcG)-marked genes that may be predisposed to aberrant DNA methylation in early stages of colorectal carcinogenesis. Aberrant methylation of TFPI2 was detected in almost all CRC adenomas (97%, n = 56) and stages I to IV CRCs (99%, n = 115). We further explored the potential of TFPI2 as a biomarker for the early detection of CRC using stool DNA-based assays in patients with nonmetastatic CRC and average-risk noncancer controls who were candidates for screening. TFPI2 methylation was detected in stool DNA from stage I to III CRC patients with a sensitivity of 76% to 89% and a specificity of 79% to 93%. Detection of TFPI2 methylation in stool DNA may act as a useful adjunct to the noninvasive strategies for screening of CRCs in the future.

Abstract
OBJECTIVES Disease course in inflammatory bowel disease (IBD) is variable and difficult to predict. To optimize prognosis, it is of interest to identify phenotypic characteristics at disease onset and other prognostic factors that predict disease course. The aim of this study was to evaluate such factors in a population-based IBD group. METHODS IBD patients diagnosed between 1 January 1991 and 1 January 2003 were included. A follow-up questionnaire was developed and medical records were reviewed. Patients were classified according to phenotype at diagnosis and risk factors were registered. Disease severity, cumulative medication use, and "surgical" and "nonsurgical" recurrence rates were calculated as outcome parameters. RESULTS In total, 476 Crohn's disease (CD), 630 ulcerative colitis (UC), and 81 indeterminate colitis (IC) patients were diagnosed. In CD (mean follow-up 7.6 years), 50% had undergone resective surgery. In UC (mean follow-up 7 years), colectomy rate was 8.3%. First year cumulative recurrence rates per 100 patient-years for CD, UC, and IC were 53, 44, and 42%, respectively. In CD, small bowel localization and stricturing disease were negative prognostic factors for surgery, as was young age. Overall recurrence rate was increased by young age and current smoking. In UC, extensive colitis increased surgical risk. In UC, older age at diagnosis initially increased recurrence risk but was subsequently protective. CONCLUSIONS This population-based IBD study showed high recurrence rates in the first year. In CD, small bowel localization, stricturing disease, and young age were predictive for disease recurrence. In UC, extensive colitis and older age at diagnosis were negative prognostic predictors.

Abstract
BACKGROUND AND AIMS Communication to patients of information about their disease has become increasingly important in modern medicine, and particularly with chronic nonfatal disorders like inflammatory bowel disease (IBD), but the subject is not adequately researched or understood. METHODS We studied the media and preferences for communication of information in a multi-national community-based inception cohort of European and Israeli patients with IBD and 10 years follow-up, using structured questionnaires categorizing demographics, disease status, current and preferred sources of information, use of electronic media, role of patients' associations, and satisfaction level. RESULTS The 917 patients completing the questionnaire were derived from northern (60%) and southern (40%) countries. The mean age was 48.3 years (62% under 50 years); 51% were males; 67% had ulcerative colitis, 33% Crohn's disease. Sixty-six percent of patients designated the specialist as their primary source of information, 77% indicated satisfaction with their current information, and 65% reported not receiving information about medical treatment in the past year. Patient concerns were about new research into their illness (64%), medical treatments (58%), risks and complications (51%) and genetics (42%). Preferred sources of information were paper bulletin (76%), electronic media (30%) and international organization (79%). Diagnosis (ulcerative colitis or Crohn's disease), gender, education level and country impacted significantly on patients' choices. CONCLUSIONS In providing health care information to patients with IBD their individual attitudes and preferences must be considered. There should be greater roles for IBD patients' associations and international IBD-research organizations, and an increasing use of electronic media.

Abstract
BACKGROUND One of the side effects of antimicrobial therapy is a disturbance of the intestinal microbiota potentially resulting in antibiotic-associated diarrhea (AAD). In this placebo-controlled double-blind study, the effect of a multispecies probiotic on the composition and metabolic activity of the intestinal microbiota and bowel habits was studied in healthy volunteers taking amoxycillin. METHODS Forty-one healthy volunteers were given 500 mg amoxycillin twice daily for 7 days and were randomized to either 5 g of a multispecies probiotic, Ecologic AAD (10(9) cfu/g), or placebo, twice daily for 14 days. Feces and questionnaires were collected on day 0, 7, 14, and 63. Feces was analyzed as to the composition of the intestinal microbiota, and beta-glucosidase activity, endotoxin concentration, Clostridium difficile toxin A, short chain fatty acids (SCFAs), and pH were determined. Bowel movements were scored according to the Bristol stool form scale. RESULTS Mean number of enterococci increased significantly from log 4.1 at day 0 to log 5.8 (day 7) and log 6.9 (day 14) cfu/g feces (P < 0.05) during probiotic intake. Although no other significant differences were observed between both intervention groups, within each group significant changes were found over time in both microbial composition and metabolic activity. Moreover, bowel movements with a frequency >or=3 per day for at least 2 days and/or a consistency >or=5 for at least 2 days were reported less frequently in the probiotic compared to the placebo group (48%vs 79%, P < 0.05). CONCLUSIONS Apart from an increase in enterococci no significant differences in microbial composition and metabolic activity were observed in the probiotic compared with the placebo group. However, changes over time were present in both groups, which differed significantly between the probiotic and the placebo arm, suggesting that the amoxycillin effect was modulated by probiotic intake. Moreover, the intake of a multispecies probiotic significantly reduced diarrhea-like bowel movements in healthy volunteers receiving amoxycillin.

Abstract
BACKGROUND Morbid obesity is strongly associated with non-alcoholic fatty liver disease. The effects of bariatric surgery on liver tests an histological abnormalities after weight loss are controversial. AIM To review the literature on the prevalence of non-alcoholic fatty liver disease in patients with morbid obesity with respect to laboratory and histopathological parameters and the effect of weight loss on these parameters after bariatric surgery. RESULTS Standard liver tests do not seem to be a sensitive tool for the assessment and follow-up of non-alcoholic fatty liver disease in obesity. In nearly all patients with morbid obesity, histological abnormalities reflecting non-alcoholic fatty liver disease are present. Bariatric surgery in these patients will decrease the grade of steatosis. However, there are some concerns about the effect of bariatric surgery on hepatic inflammation and fibrosis. In particular, older follow-up studies reported negative results as opposed to more recent studies, which also showed improvement in hepatic inflammation and fibrosis. Unfortunately, most studies had limitations because of the selection of patients. CONCLUSION Despite limitations in many studies, bariatric surgery seems to be a promising treatment in patients with obesity presenting with non-alcoholic fatty liver disease.

Abstract
OBJECTIVE The assessment of intestinal inflammation in patients with inflammatory bowel disease (IBD) remains a difficult challenge. Both rectal nitric oxide (NO) and fecal calprotectin can be measured using non-invasive methods and are emerging as promising inflammatory markers in IBD. In this study the aim was to compare calprotectin and NO levels in IBD patients. MATERIAL AND METHODS Rectal NO was measured tonometrically in 23 healthy volunteers and 32 patients with IBD. In addition, we collected stool samples from all subjects for measurement of fecal calprotectin and nitrate/nitrite (NO metabolites). RESULTS Patients with IBD had greatly increased NO and calprotectin levels compared to healthy volunteers (p <0.001). In addition, the nitrate levels were slightly increased in IBD patients. A weak correlation was found between rectal NO levels, disease activity and number of loose stools in IBD patients (Spearman's rho 0.37 and 0.51, respectively; p <0.05). Fecal calprotectin correlated only with age (Spearman's rho 0.51; p <0.01). However, no correlation was found between NO and calprotectin. CONCLUSIONS Both rectal NO and fecal calprotectin are greatly increased during bowel inflammation, but they may reflect different parts of the inflammatory process. Future studies will elucidate the clinical usefulness of these two markers.

Abstract
BACKGROUND In several open and 1 controlled trial, unfractionated heparin was effective in the treatment of active ulcerative colitis (UC). Low molecular weight heparin (LMWH) had a similar effect in several open studies. METHODS We studied the efficacy, safety, and tolerability of LMWH in mild to moderately active UC in a randomized, double-blind, placebo-controlled trial. In all, 29 patients with a mild or moderate recurrence of UC during salicylate treatment were randomized to receive either reviparin 3,436 IU (n = 15) subcutaneously twice daily or placebo (n = 14). The study period was 8 weeks. Treatment was discontinued if there was no improvement at 4 weeks or at any disease progression. Primary outcome measure was clinical improvement at 8 weeks measured by the Colitis Activity Index (CAI) and the Clinical Symptoms Grading (CSG, based on the CAI). Endoscopic and histologic grading and quality of life as measured by the Inflammatory Bowel Disease Questionnaire (IBDQ) were secondary outcome measures. Patients were closely monitored for adverse events. RESULTS Twenty of 29 patients finished the 8-week treatment period (reviparin versus placebo: 11 versus 9; P = 0.70). There was no difference in CSG, CAI, endoscopic and histologic grading, or IBDQ. Treatment was well tolerated and no serious adverse events occurred. CONCLUSION In this study, treatment with LMWH showed no significant clinical advantage compared to placebo in mild to moderately active UC.

Abstract
BACKGROUND Population based studies have revealed varying mortality for patients with ulcerative colitis but most have described patients from limited geographical areas who were diagnosed before 1990. AIMS To assess overall mortality in a European cohort of patients with ulcerative colitis, 10 years after diagnosis, and to investigate national ulcerative colitis related mortality across Europe. METHODS Mortality 10 years after diagnosis was recorded in a prospective European-wide population based cohort of patients with ulcerative colitis diagnosed in 1991-1993 from nine centres in seven European countries. Expected mortality was calculated from the sex, age and country specific mortality in the WHO Mortality Database for 1995-1998. Standardised mortality ratios (SMR) and 95% confidence intervals (CI) were calculated. RESULTS At follow-up, 661 of 775 patients were alive with a median follow-up duration of 123 months (107-144). A total of 73 deaths (median follow-up time 61 months (1-133)) occurred compared with an expected 67. The overall mortality risk was no higher: SMR 1.09 (95% CI 0.86 to 1.37). Mortality by sex was SMR 0.92 (95% CI 0.65 to 1.26) for males and SMR 1.39 (95% CI 0.97 to 1.93) for females. There was a slightly higher risk in older age groups. For disease specific mortality, a higher SMR was found only for pulmonary disease. Mortality by European region was SMR 1.19 (95% CI 0.91 to 1.53) for the north and SMR 0.82 (95% CI 0.45-1.37) for the south. CONCLUSIONS Higher mortality was not found in patients with ulcerative colitis 10 years after disease onset. However, a significant rise in SMR for pulmonary disease, and a trend towards an age related rise in SMR, was observed.

Abstract
OBJECTIVE Geographic differences in disease course of Crohn's disease (CD) might possibly be related to differences in genetic and environmental factors encountered in different parts of the world. The aim of this study was to assess differences in treatment regimens within a European cohort of CD patients as a reflection of disease course, and to identify associated phenotypic risk factors at diagnosis. MATERIAL AND METHODS A prospective European population-based inception cohort of 380 CD patients was studied. The patients were classified for phenotype according to the Vienna classification. Differences between Northern and Southern European centres in treatment over the first 10 years of disease were analysed using a competing risks survival analysis method. RESULTS Patients in the North were more likely to have had surgery (p<0.01), whereas patients in the South were more likely to have been treated medically (p<0.01). Phenotype at diagnosis was not predictive of differences in treatment regimens between North and South. CONCLUSIONS In this study, a difference in management of CD was observed between Northern and Southern European centres. This suggests that there may be a North-South disease severity gradient across Europe. Phenotypic differences between patients in the North and South did not explain this observed difference.

Abstract
BACKGROUND In ulcerative colitis (UC), a state of hypercoagulation has frequently been observed. Low molecular weight heparin (LMWH) has shown beneficial effects as an adjuvant treatment of steroid refractory UC in open trials. We assessed potential therapeutic effects of the LMWH reviparin in hospitalised patients with mesalazine refractory UC, as well as its influence on haemostasis factors. METHODS Twenty-nine patients with mild-to-moderately active UC were included in a double-blind placebo controlled trial. All patients had a flare-up of disease under mesalazine treatment. Reviparin (Clivarin) 3,436 IU anti-Xa/0.6 ml or placebo s.c. was added, and self-administered twice daily for 8 weeks. Patients were monitored for possible adverse events and changes in clinical symptoms. Endoscopical, histological, biochemical and haemostasis parameters were analysed. RESULTS Tolerability and compliance were excellent and no serious adverse events occurred. No significant differences were observed on the clinical, endoscopical and histological outcome, as compared to placebo. A high intrinsic and extrinsic thrombin potential was found before LMWH therapy. However, the significant reduction in the thrombin generation by LMWH was not related to the reduction in disease activity. CONCLUSION The LMWH reviparine reduces thrombin generation in patients with mild-to-moderately active, mesalazine refractory UC, but is not associated with a reduction in disease activity.

Abstract
BACKGROUND 6-Thioguanine is used in inflammatory bowel disease since 2001, with promising short-term results. In 2003, liver histology of some 6-thioguanine treated patients showed nodular regenerative hyperplasia. Recently, magnetic resonance imaging revealed nodular regenerative hyperplasia in patients with normal histology. AIMS Investigating the presence of nodular regenerative hyperplasia in long-term 6-thioguanine treated patients. PATIENTS AND METHODS Inflammatory bowel disease patients, using 6-thioguanine minimally 24 months, were asked to undergo liver biopsy and magnetic resonance imaging. RESULTS Fourteen patients used 6-thioguanine minimally 24 months, 13 participated. Mean 6-thioguanine therapy duration, daily dose and 6-thioguanine nucleotide levels were: 36 months, 18.8 mg (0.28 mg/kg) and 705 pmol/8x10(8) erythrocytes, respectively. Liver histology and magnetic resonance imaging showed no nodular regenerative hyperplasia. DISCUSSION Liver biopsy and magnetic resonance imaging showed no nodular regenerative hyperplasia in these long-term 6-thioguanine treated inflammatory bowel disease patients. 6-thioguanine dose and metabolite levels were lower compared with previous nodular regenerative hyperplasia reports, suggesting dose or metabolite level-dependent effects. Otherwise, nodular regenerative hyperplasia is related with inflammatory bowel disease itself and immunosuppressives, including azathioprine and 6-mercaptopurine. CONCLUSION 6-Thioguanine is debated due to nodular regenerative hyperplasia. We found no nodular regenerative hyperplasia in inflammatory bowel disease patients with long-term, low dosed 6-thioguanine, suggesting metabolite level-dependent effects. Therefore, 6-thioguanine still seems useful, but in selected patients, intolerant for other immunosuppressives, low dosed and under close surveillance of metabolite levels and hepatotoxity.

Abstract
BACKGROUND & AIMS The colectomy rate in ulcerative colitis (UC) is related to morbidity and to treatment decisions made during disease course. The aims of this study were to determine the colectomy risk in UC in the first decade after diagnosis and to identify factors that may influence the choice of surgical treatment. METHODS In 1991-1993, 781 UC patients from 9 centers located in 7 countries in northern and southern Europe and in Israel were included in a prospective inception cohort study. After 10 years of follow-up, 617 patients had complete medical records, 73 had died, and 91 had been lost to follow-up. RESULTS There were no significant differences in age, sex, or disease extent at diagnosis between patients followed for 10 years and those lost to follow-up. The 10-year cumulative risk of colectomy was 8.7%: 10.4% in the northern and 3.9% in the southern European centers (P < .001). Colectomy was more likely in extensive colitis than in proctitis, with an adjusted hazard ratio (HR) of 4.1 (95% CI: 2.0-8.4). Compared with the southern centers, the adjusted HR was 2.7 (95% CI: 1.3-5.6) for The Netherlands and Norway together and 8.2 (95% CI: 3.6-18.6) for Denmark. Age at diagnosis, sex, and smoking status at diagnosis had no statistically significant influence on colectomy rates. CONCLUSIONS The colectomy rate was found to be lower than that in previous publications, but there was a difference between northern and southern Europe. Colectomy was associated with extensive colitis, but the geographic variations could not be explained.

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
BACKGROUND No previous correlation between phenotype at diagnosis of Crohn's disease (CD) and mortality has been performed. We assessed the predictive value of phenotype at diagnosis on overall and disease related mortality in a European cohort of CD patients. METHODS Overall and disease related mortality were recorded 10 years after diagnosis in a prospectively assembled, uniformly diagnosed European population based inception cohort of 380 CD patients diagnosed between 1991 and 1993. Standardised mortality ratios (SMRs) were calculated for geographic and phenotypic subgroups at diagnosis. RESULTS Thirty seven deaths were observed in the entire cohort whereas 21.5 deaths were expected (SMR 1.85 (95% CI 1.30-2.55)). Mortality risk was significantly increased in both females (SMR 1.93 (95% CI 1.10-3.14)) and males (SMR 1.79 (95% CI 1.11-2.73)). Patients from northern European centres had a significant overall increased mortality risk (SMR 2.04 (95% CI 1.32-3.01)) whereas a tendency towards increased overall mortality risk was also observed in the south (SMR 1.55 (95% CI 0.80-2.70)). Mortality risk was increased in patients with colonic disease location and with inflammatory disease behaviour at diagnosis. Mortality risk was also increased in the age group above 40 years at diagnosis for both total and CD related causes. Excess mortality was mainly due to gastrointestinal causes that were related to CD. CONCLUSIONS This European multinational population based study revealed an increased overall mortality risk in CD patients 10 years after diagnosis, and age above 40 years at diagnosis was found to be the sole factor associated with increased mortality risk.

Abstract
BACKGROUND Studies on probiotics mainly base their results on faecal samples, which may not represent the situation in the mucosa of distal and proximal colon. AIM In a placebo-controlled study, to assess the effect of Lactobacillus plantarum 299v on the bacterial composition of faecal vs. mucosal samples. METHODS Twenty-nine patients undergoing colonoscopic examination for polyps consumed a twice-daily drink with or without L. plantarum 299v (10(11) CFU/day) for 2 weeks. Faecal samples were collected before and after consumption. During colonoscopy, biopsies were collected from the ascending colon and rectum. The faecal and mucosal bacterial concentrations and prevalence were determined. RESULTS L. plantarum 299v significantly increased the concentration of faecal lactic acid bacteria, lactobacilli and clostridia, and was identified in two rectal biopsies but not in the ascending colon biopsies of probiotic-treated subjects. Concentrations and prevalence in ascending colon and rectum biopsies were comparable, but were significantly lower compared with faecal samples. CONCLUSIONS After probiotic consumption, a significant increase in the faecal concentration of lactobacilli was found but concentrations were low in biopsies. The bacterial composition in biopsies of the ascending colon and rectum did not differ based on culture techniques. To further elucidate the modes of action of probiotics, it might be necessary to study differences in colonization with molecular techniques.

Abstract
OBJECTIVE To give a general outline of a 10-year clinical follow-up study of a population-based European cohort of inflammatory bowel disease (IBD) patients and to present the first results in terms of clinical outcome parameters and risk factors. MATERIALS AND METHODS A population-based cohort of newly, prospectively, diagnosed cases was initiated between 1991 and 1993. The 2201 patients with IBD (706 had Crohn's disease (CD), 1379 had ulcerative colitis (UC) and 116 had indeterminate colitis) originated from 20 different areas in 11 different European countries and Israel. For the 10-year follow-up of this cohort, electronic data-collecting instruments were made available through an Internet-based website. Data concerning vital status, disease activity, medication use, surgical events, cancer, pregnancy, fertility, quality of life and health-care costs were gathered. A blood sample was obtained from patients and controls to perform genotypic characterization. RESULTS Thirteen centres from eight European countries and Israel participated. In 958 (316 CD and 642 UC) out of a total of 1505 IBD patients (64%) from these 13 centres, a complete dataset was obtained at follow-up. Even though an increased mortality risk was observed in CD patients 10 years after diagnosis, a benign disease course was observed in this patient group in terms of disease recurrence. A correlation between ASCA and CARD15 variants in CD patients and complicated disease course was observed. A north-south gradient was observed regarding colectomy rates in UC patients. Direct costs were found to be highest in the first year after diagnosis and greater in CD patients than in UC patients, with marked differences between participating countries. CONCLUSIONS This 10-year clinical follow-up study of a population-based European cohort of IBD patients provides updated information on disease outcome of these patient groups.

Abstract
BACKGROUND In vitro studies suggest interactions between mesalazine (mesalamine) and thiopurines by thiopurine S-methyltransferase (TPMT) inhibition, influencing the balance of hepatotoxic 6-methylmercaptopurine ribonucleotide and immunosuppressive tioguanine (thioguanine) metabolites. AIM To examine the in vivo pharmacokinetic interaction between mesalazine and mercaptopurine. METHODS A prospective study was performed in quiescent inflammatory bowel disease patients using the combination of mercaptopurine and mesalazine. Laboratory parameters, 6-methylmercaptopurine ribonucleotide and tioguanine levels and thiopurine S-methyltransferase activity in erythrocytes were measured at stable medication, after mesalazine discontinuation and mesalazine reintroduction, further mercaptopurine was continued. RESULTS Seventeen patients were participated. Mean mercaptopurine dose was 0.78 mg/kg/day and median of mesalazine dose was 3000 mg/day. After mesalazine discontinuation, mean tioguanine levels changed significantly from 262 to 209 pmol/8 x 10(8) red blood cell, increasing to 270 after reintroduction. Mean 6-methylmercaptopurine ribonucleotide levels were 1422, 2149 and 1503 pmol/8 x 10(8) red blood cell respectively. Mean 6-methylmercaptopurine ribonucleotide/tioguanine ratio increased significantly from 6.3 at baseline to 11.2. Mean baseline thiopurine S-methyltransferase activity was 0.58 pmol/10(6) red blood cell/h and stable. All patients had wild-type thiopurine S-methyltransferase genotypes however, leucocyte counts were stable. DISCUSSION A significantly higher tioguanine levels and improving 6-methylmercaptopurine ribonucleotide/tioguanine ratio were found during mesalazine/mercaptopurine combination. Theoretically, mesalazine inhibits thiopurine S-methyltransferase activity. In vivo thiopurine S-methyltransferase activity did not change, however. CONCLUSION Mesalazine has synergistic effects on mercaptopurine therapy, but the mechanism is unclear. Combining these drugs may be further indication for mesalazine in inflammatory bowel disease treatment.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder that is frequently seen in gastroenterological practice. Population-based studies have shown that at any point in time IBS symptoms are present in about 3%-22% of the general Western population. In general practice, half of all new patients have functional disorders and IBS is responsible for about five consultations per week. General practitioners (GPs) manage the majority of IBS patients, but most knowledge (and research) is based on the smaller percentage of patients managed in secondary care. There is a paucity of literature on differences or similarities between these two groups with regard to clinical characteristics or diagnostic approach. METHODS The literature published in English about IBS in general practice was reviewed. CONCLUSIONS Irritable bowel syndrome is frequently encountered in primary care. Primary care IBS patients, compared to secondary care patients, are likely to be young, female and to have less severe symptoms. But this is only true for some symptoms; for example, non-abdominal complaints are equally reported in both groups. The disorder can be diagnosed safely using internationally agreed symptom-based criteria, such as the Rome II criteria. Additional diagnostic measures will be necessary to support the diagnosis in only a minority of situations. Many primary care IBS patients can be managed given adequate reassurance and education, frequently without additional pharmacological treatment.

Abstract
BACKGROUND & AIMS Osteoporosis frequently occurs in Crohn's disease, often because of corticosteroids. Budesonide as controlled release capsules is a locally acting corticosteroid with low systemic bioavailability. We investigated its effects on bone compared with prednisolone. METHODS In 34 international centers, 272 patients with Crohn's disease involving ileum and/or colon ascendens were randomized to once daily treatment with budesonide or prednisolone for 2 years at doses adapted to disease activity. One hundred eighty-one corticosteroid-free patients had active disease (98 had never received corticosteroids, corticosteroid naive; 83 had received corticosteroids previously, corticosteroid exposed), and 90 had quiescent disease, receiving long-term low doses of corticosteroids, corticosteroid-dependent; in 1 patient, no efficacy data were obtained. Bone mineral density and fractures were assessed in a double-blinded fashion; disease activity, side effects, and quality of life were monitored. RESULTS Neither the corticosteroid-free nor the corticosteroid-dependent patients treated with budesonide differed significantly in bone mineral density from those receiving prednisolone. However, corticosteroid-naive patients receiving budesonide had smaller reductions in bone mineral density than those on prednisolone (mean, -1.04% vs -3.84%; P = .0084). Treatment-emergent corticosteroid side effects were less frequent with budesonide. Efficacy was similar in both groups. CONCLUSIONS Treatment with budesonide is associated with better preserved bone mass compared with prednisolone in only the corticosteroid-naive patients with active ileocecal Crohn's disease. In both the corticosteroid-free and corticosteroid-dependent groups, budesonide and prednisolone were equally effective for up to 2 years, but budesonide caused fewer corticosteroid side effects.

Abstract
Quality of life is reduced in patients with irritable bowel syndrome, and the costs for this disease are substantial to society. During a meeting in London, UK, the IBiS club reviewed the literature on these subjects. Drawbacks and advantages with existing instruments to assess quality of life and costs were discussed and the clinical and scientific relevance of the current knowledge was assessed. A summary from the meeting is presented in this paper.

Abstract
BACKGROUND Disease outcome in Crohn's disease might have changed during the last four decades. Disease outcome measurement in Crohn's disease has methodological difficulties because of patient selection and lack of proper definition of diagnostic and outcome measurement criteria. AIM To assess possible changes in disease outcome in Crohn's disease during the last four decades. METHODS A systematic literature search was performed using the MEDLINE search engine and major international conference libraries. Articles and abstracts were selected according to stringent inclusion criteria. RESULTS Forty articles and nine abstracts complied with the inclusion criteria. Seven studies with a median follow-up time between 11.1 and 17 years showed standard mortality ratios in Crohn's disease ranging between 2.16 and 0.72 with a tendency of decline during the last four decades. One study with 11.4 years mean follow-up time showed a statistically significant increased relative risk for colorectal cancer that was not confirmed by three others. Sixteen publications applied in the disease recurrence category. Probability of first resective surgery ranged between 38 and 96% during the first 15 years after diagnosis. The overall recurrence and surgical recurrence rates after first resective surgery ranged between 50 and 60, and 28 and 45% respectively during the following 15 years without an apparent time trend. CONCLUSION This structured literature review provides no hard evidence for change in disease outcome in Crohn's disease during the last four decades.

Abstract
BACKGROUND In inflammatory bowel disease (IBD), gut microvascular thrombosis as well as thromboembolic complications have repeatedly been observed. We examined the long-term course of markers of coagulation and fibrinolysis in relation to clinical disease activity. MATERIALS AND METHODS In a prospective study, prothrombin fragment 1 and 2 (F1.2), thrombin-antithrombin complex (TAT), antithrombin, D-dimer, plasmin-alpha(2)-antiplasmin complex (PAP) and plasminogen activator inhibitor-1 (PAI-1) were measured in 20 patients with Crohn's disease (CD), 18 with ulcerative colitis (UC), and 19 with giant cell arteritis during active and inactive disease, as well as in 51 controls without inflammation. RESULTS Levels of F1.2, TAT, D-dimer, PAP and PAI-1 were significantly higher in active versus inactive CD and UC. However, even after 12 months of follow-up, in CD and UC the mean levels of F1.2, D-dimer and PAP were significantly higher than the levels of the controls. CONCLUSIONS Levels of F1.2, D-dimer and PAP were markedly raised for a long time in clinically inactive IBD, underlining a chronic state of hypercoagulation and enhanced fibrinolysis.

Abstract
In the literature there are indications of associations between health-related quality of life (HRQoL) in inflammatory bowel disease and disease activity, psychological status, coping, stressful life events, and social support. The aim of this study was to examine whether a relation exists between quality of health care and HRQoL, taking possible confounding variables into account. For this purpose, one single questionnaire was compiled from existing validated questionnaires. A population-based inception cohort of 1056 patients with inflammatory bowel disease in eight countries, diagnosed 6 to 8 years prior to the study, was approached to participate. In total, 824 patients responded (78%), and 517 could be included in statistical analyses. It was shown that in inflammatory bowel disease HRQoL was indeed influenced by quality of care (particularly with regard to the parameters of "providing information," "costs," and "courtesy"), as well as by disease activity, psychological status, type of hospital, social support, stressful life events, and way of administration of the questionnaire. Patients with active disease had lower psychological status and HRQoL scores at the time of the survey than patients without active disease. However, quality of care scores did not differ between these groups. The care aspect "costs" was scored worse by CD compared with UC patients, probably caused by a potentially more expensive treatment. In conclusion, it is shown in a large exploratory study, for the first time, that in inflammatory bowel disease, quality of care has a significant role in determining health-related quality of life.

Abstract
Background: An observational study was conducted at eight university and four district hospitals in eight countries collaborating in clinical and epidemiological research in inflammatory bowel disease (IBD) to compare European health care facilities and to define current "best practice" with regard to IBD. Methods: The approach used in this multi-national survey was unique. Existing quality norms, developed for total hospital care by a specialized organization, were restricted to IBD-specific care and adapted to the frame of reference of the study group. In each center, these norms were surveyed by means of questionnaires and professional audits in all participating centers. The collected data were reported to the center, compared to data from other hospitals, and used to benchmark. Group consensus was reached with regard to defining current "best practice". Results: The observations in each center involved patient-oriented processes, technical and patient safety, and quality of the medical standard. Several findings could be directly implemented to improve IBD care in another hospital (benchmarks). These included a confidential relationship between health care worker(s) and patients, and availability of patient data. Conclusions: The observed benchmarks, in combination with other subjectively chosen "positive" procedures, have been defined as current "best practice in IBD", representing practical guidelines towards better quality of care in IBD.

Abstract
BACKGROUND Colorectal cancer (CRC) is the second commonest cause of cancer death in the Western world. In The Netherlands, CRC causes about 4400 deaths per year, and its diagnosis and treatment make up for a large share of health-care costs. METHODS Review and discussioN. RESULTS Experts in the field presently assume that screening for CRC and its precursor lesions, colorectal adenomas (CRAs), could prevent death from colorectal neoplasia by more than 80%. Additionally, there is increasing acknowledgement that CRC screening programmes can save lives at a cost similar to, or even less than, the generally accepted breast cancer or cervical cancer screening programmes. Nonetheless, while neighbouring countries have taken vigorous measures to fight CRC, the Dutch are still hesitating in this matter. This is partly due to some yet unanswered questions concerning the acceptability of screening for CRC in the general population, the starting age and the frequency of screening, the type of screening tests to be used, and the programme organization. In this commentary, general epidemiological and pathogenetic aspects of CRC are addressed. In addition, some frequently asked questions (FAQ) and (very subjective) answers about screening for CRC are offered, as potential substrate for further in-depth discussions. CONCLUSION The emerging message for the community is that an effective national screening programme is urgently required to reduce the substantial morbidity and mortality from this disease.

Abstract
BACKGROUND Different food items are made responsible for irritable bowel syndrome (IBS) symptoms, but the physiopathology of IBS remains unclear. AIMS During a meeting in Nice, France, experts of the European Working Team of the IBiS Club discussed selected data regarding the relationships between alimentation, food items (including fibers) and IBS symptoms. METHODS/RESULTS Food allergy remains a difficult diagnosis, but medical and general history, presence of general symptoms such as skin rash, and hypersensitivity tests may help in achieving a positive diagnosis. On the other hand, food intolerance is more confusing because of the subjectivity of the relationship between ingestion of certain foods and the appearance of clinical symptoms. Different food items which are commonly implicated in adverse reactions mimicking IBS were found to be stimulants for the gut, suggesting that patients with predominant diarrhea IBS have to be carefully questioned about consumption of different kinds of food (i.e., coffee, alcohol, chewing gum, soft drinks) and not only on lactose ingestion. Gas production is discussed on the basis of retention of intestinal gas as well as on malabsorption of fermentable substrates. The role of a large amount of this kind of substrate reaching the colon is suggested as a potential mechanism of IBS-type symptoms in overeating patients. Regarding the role of fiber in IBS, the expert group concluded that fibers are not inert substances and that they could trigger pain or bloating in some IBS patients. CONCLUSION Despite numerous reviews on this subject, it is very difficult to give general dietary advice to IBS patients, but dieteticians may have a positive role in managing such patients.

Abstract
BACKGROUND AND AIMS Elevated serum gastrin and a low pepsinogen A/C ratio are well-recognized markers for atrophic body gastritis (ABG). We have shown that the presence of body atrophy is also associated with elevated serum pro-inflammatory cytokines. This study tested the hypothesis that serum cytokines provide additional information to gastrin and pepsinogens in screening for ABG. METHODS Two hundred and twenty-six consecutive patients were investigated on referral for upper gastrointestinal endoscopy: 150 were patients with gastro-oesophageal reflux disease, receiving acid inhibitory medication either with proton pump inhibitors (n = 113) or with histamine2-receptor antagonists (n = 37), and 76 were nontreated controls, who had normal endoscopic findings. Gastric mucosal biopsies were sampled for histological examination (Sydney classification). Serum samples were analyzed for gastrin, chromogranin A (CgA), and pepsinogens A and C by RIA, and for the interleukins (IL)-1beta, IL-6, and IL-8 by ELISA. RESULTS Subjects with ABG had significantly higher serum gastrin (P < 0.01) and serum CgA (P < 0.01) levels and significantly lower pepsinogen A/C ratios (P < 0.001) than those without ABG. Additionally, serum IL-1beta, IL-6 and, especially, IL-8 levels were significantly higher in the subjects with than in those without ABG (P < 0.0001, for all cytokines). To optimize the detection of body atrophy we defined the ABG index: the ratio between the simultaneously measured IL-8 and pepsinogen A/C. The area under the ROC curve for the ABG index was significantly greater than that for serum gastrin and for serum pepsinogen A/C alone (0.91 +/- 0.029 vs. 0.72 +/- 0.042, and vs. 0.83 +/- 0.031, P = 0.018 and P = 0.049). Using the ABG index at a cut-off value of 1.8 pg mL-1, 91% of the cases were classified correctly. CONCLUSIONS The ratio between serum IL-8 and pepsinogen A/C accurately predicts the presence of ABG. We therefore propose the ABG index as a noninvasive screening test for ABG in population-based studies.

Abstract
INTRODUCTION Inflammatory bowel diseases are chronic conditions that might cause a severe impact on social life. The aim of the study was to assess employment, chronic work disability, and sick leave in patients with inflammatory bowel disease. METHODS A postal questionnaire was sent to 984 patients with inflammatory bowel disease and 1504 controls. Age- and gender-adjusted employment and chronic work disability ratios and rates were calculated using indirect standardization. In subjects in paid employment, proportions of those having an episode of sick leave and lost workdays were analyzed. Logistic regression was used to assess the contribution of age, gender, education, and course of disease. RESULTS The results of 680 (69%) patients and 715 (48%) controls could be analyzed. For the entire group of patients, employment was 6.5% lower, compared with controls (95% CI: 4.0-9.0). Chronic work disability was 17.1% higher than expected (95% CI: 15.1-19.1). In those in paid employment, 62% of patients compared with 53% of controls had experienced one or more episodes of sick leave during the past year (p = 0.002). This resulted in 19.2 versus 11.8 days of sick leave per subject per year for patients and controls respectively (p = 0.002). Relative to controls, the risk of chronic work disability was more increased in younger (p = 0.02) and higher educated (p = 0.02) patients. Course of disease contributed to chronic work disability and sick leave. CONCLUSION IBD has a significant impact on labor force participation that is higher in CD compared with UC and highest in younger and more highly educated patients.

Abstract
Three primigravidae were admitted during the first trimester of pregnancy with nausea, vomiting, ketonuria and liver enzyme elevation of varying severity. A 29-year-old woman had elevated aminotransferase values, at levels described in the literature (ASAT 112 U/l, ALAT 214 U/l). The second patient, a woman aged 26 years, had undergone in vitro fertilisation and showed higher liver enzyme elevation, including the total bilirubin level (ASAT 250 U/l, ALAT 474 U/l, total bilirubin 59.8 micromol/l). A 30-year-old woman had extremely high aminotransferase values (ASAT 705 U/l, ALAT 1674 U/l) and she is the first reported patient with ALAT values exceeding 1,000 U/l in connection with hyperemesis gravidarum. Gallstone disease, viral and drug-induced hepatitis were excluded in all of these patients. Treatment was symptomatic and the abnormal liver tests returned to normal promptly when the vomiting resolved, independent of the severity of liver enzyme elevation. The pregnancies proceeded normally and all three patients delivered healthy babies.

Abstract
BACKGROUND A high prevalence of osteoporosis has been noted in Crohn's disease, but data about fractures are scarce. METHODS The relationship between low bone mineral density and the prevalence of vertebral fractures was studied in 271 patients with ileo-caecal Crohn's disease in a large European/Israeli study. One hundred and eighty-one currently steroid-free patients with active Crohn's disease (98 completely steroid-naive) and 90 steroid-dependent patients with inactive or quiescent Crohn's disease were investigated by dual X-ray absorptiometry scan of the lumbar spine, a standardized posterior/anterior and lateral X-ray of the thoracic and lumbar spine, and an assessment of potential risk factors for osteoporosis. RESULTS Thirty-nine asymptomatic fractures were seen in 25 of 179 steroid-free patients (14.0%; 27 wedge, 12 concavity), and 17 fractures were seen in 13 of 89 steroid-dependent patients (14.6%; 14 wedge, three concavity). The prevalence of fractures in steroid-naive patients was 12.4%. The average bone mineral density, expressed as the T-score, of patients with fractures was not significantly different from that of those without fractures (-0.759 vs. -0.837; P=0.73); 55% of patients with fractures had a normal T-score. The bone mineral density was negatively correlated with lifetime steroids, but not with previous bowel resection or current disease activity. The fracture rate was not correlated with the bone mineral density (P=0.73) or lifetime steroid dose (P=0.83); in women, but not in men, the fracture rate was correlated with age (P=0.009). CONCLUSIONS The lack of correlation between the prevalence of fractures on the one hand and the bone mineral density and lifetime steroid dose on the other necessitates new hypotheses for the pathogenesis of the former.

Abstract
BACKGROUND Infusion of anti-tumour necrosis factor-alpha appears to be highly effective in patients with Crohn's disease. AIM To assess the effect of infliximab on the quality of life in patients with active or fistulizing disease, as measured by the inflammatory bowel disease questionnaire, and to examine the impact on its four dimensions. METHODS An observational study was conducted in 65 patients. An infusion of 5 mg/kg infliximab was given at week 0 in patients with active disease and at week 0, 2 and 6 in fistulizing disease. Changes from baseline in the total and dimensional inflammatory bowel disease questionnaire scores were calculated and compared between the patient groups. Potential predictors of change in the quality of life were identified. RESULTS In the active disease group, at week 4, the mean total and dimensional inflammatory bowel disease questionnaire scores improved compared to baseline (P < 0.001). In the fistulizing group, at week 6, all scores changed from baseline (P < 0.05). Improvement in the total inflammatory bowel disease questionnaire score correlated well with the improvement of the Crohn's disease activity index. Systemic and social scores improved more than bowel and emotional scores. Inflammatory Crohn's disease and a young age at diagnosis were predictors for a better response to infliximab therapy. CONCLUSIONS Infliximab therapy improves all dimensions of the quality of life in patients with Crohn's disease.

Abstract
Pneumatosis cystoides intestinalis (PCI) is a disease in which small gas-filled cysts appear in the intestinal wall. Four cases presented here demonstrate the diversity of the associated diseases. In two of the patients constipation probably played a role; in the third patient decreased colonic motility, elevated intestinal pressure and increased mucosal permeability in the context of enteritis treated with codeine was the underlying problem; in the fourth high protein feeding and bowel ischaemia was diagnosed. Various aetiologies are presented in the literature. There is no specific history and physical or laboratory findings do not help to diagnose PCI. Plain abdominal film, ultrasound, computer tomography, magnetic resonance imaging, barium contrast studies and/or endoscopy may be necessary for diagnosis. Therapy is based on enhancing partial oxygen pressure in the bowel wall. PCI usually runs a benign course.

Abstract
BACKGROUND In ulcerative colitis, a state of hypercoagulation has frequently been observed. Unfractionated heparin has shown beneficial effects as an adjuvant treatment of steroid refractory ulcerative colitis in open trials and in one placebo-controlled trial. Low molecular weight heparin (LMWH) offers advantages in the method of administration, but it has not been evaluated in severe ulcerative colitis. We therefore assessed the tolerability, safety and potential therapeutical effects of LMWH in hospitalized patients with steroid refractory ulcerative colitis. METHODS Twenty-five patients with severely active ulcerative colitis were included in an open-labelled trial. All patients had a flare-up of disease under glucocorticosteroid treatment. Nadroparine calcium 5.700 IE anti-Xa/0.6 mL s.c. was self-administered twice daily for 8 weeks. Patients were monitored for possible adverse events, and changes in clinical symptoms and in laboratory, endoscopical and histological results were analysed. RESULTS Tolerability and compliance were excellent and no serious adverse events occurred. In 20 of 25 patients, a good clinical and laboratory response was observed. Also, the endoscopic and histological signs of inflammation were found to be significantly improved. However, this was not accompanied by a significant reduction in the number of mucosal microvascular thrombi after 8 weeks of LMWH treatment. CONCLUSION LMWH may be a safe adjuvant therapy for patients with active, glucocorticosteroid refractory ulcerative colitis.

Abstract
BACKGROUND Musculoskeletal disorders are the most common extra-intestinal manifestation of inflammatory bowel disease (IBD). Wide ranges of prevalence have been reported depending on the criteria used to define spondylarthropathy and on the selection of patients. We aimed to evaluate the prevalence and clinical spectrum of musculoskeletal manifestations in an inception cohort of European IBD patients. METHODS From 1 October 1991 to 30 September 1993, 202 IBD patients were diagnosed in three centres of two countries (Italy and The Netherlands) by means of a population-based inception cohort study. Of this group of patients, 160 (79%) were interviewed and examined by a rheumatologist and a gastroenterologist in the period June-September 1996. A total of 139/160 patients had an antero-posterior radiograph of the pelvis, and in 140/160 HLA-B27 was determined. RESULTS 53 (33.1%) of the 160 patients had experienced at least one musculoskeletal manifestation, 29 (18.1%) satisfied the European Spondylarthropathy Study Group (ESSG) criteria for spondylarthropathy and 5 (3.1%) satisfied the modified New York criteria for ankylosing spondylitis. However, 23 (14.4%) patients developed one or more spondylarthropathy-related manifestations without fulfilling any of the classification criteria. In patients satisfying ESSG criteria a significantly higher frequency of women (P = 0.03), of ocular and liver involvement (P = 0.01 and P = 0.03, respectively), and use of immunosuppressive drugs (P = 0.02) was observed. CONCLUSION Our study shows a high prevalence of musculoskeletal manifestations in an inception cohort of IBD patients. The clinical spectrum is broader than that defined by spondylarthropathy criteria.

Abstract
Acid-suppressive therapy and subsequent changes in gastric mucosa and luminal environment rank highly amongst the investigated issues in gastroenterology over the past two to three decades. Herewith, we present an overview of these intragastric changes, particularly during long-term administration of acid-suppresive medication and concurrent infection with Helicobacter pylori. Current evidence indicates that: i) Long-term acid suppression facilitates the development of fundic ECL cell hyperplasia, especially in the presence of Helicobacter pylori. No neoplastic changes directly attributable to acid suppression have so far been demonstrated in humans. ii) Acid-suppressive therapy increases the risk of enteric infections. iii) Acid-suppressive therapy does not alter fat and mineral bioavailability, but may decrease the absorption of protein-bound vitamin B12. iv) Acid suppression invariably results in intragastric overgrowth of non-Helicobacter pylori bacterial species. The concurrent infection with Helicobacter pylori may promote this bacterial overgrowth and the intragastric formation of N-nitrosamines. v) Acid-suppressive therapy alters the natural course of Helicobacter pylori gastritis, transforming the antral-predominant pattern into a body-predominant pattern, which in turn may progress to body gland atrophy. The pathophysiology of this phenomenon is currently under investigation. vi) In view of the potential adverse effects of acid suppression in the presence of Helicobacter pylori, the screen-and-treat strategy is advocated for Helicobacter pylori in subjects considered for long-term treatment.

Abstract
BACKGROUND Serum chromogranin A (CgA), a marker of neuroendocrine neoplasia, increases during profound gastric acid inhibition, possibly reflecting the trophic effect of gastrin on the enterochromaffin-like (ECL) cells. AIMS This study investigated the clinical value of serum CgA as a screening test for gastric fundic enterochromaffin-like (ECL) cell hyperplasia during acid-suppressive therapy. METHOD A consecutive series of 230 dyspeptic patients referred for upper gastrointestinal endoscopy was investigated in a cross-sectional design. They were 154 patients on continuous medium-term (6 weeks to one year) or long-term (longer than one year) acid inhibition with either proton pump inhibitors (PPIs, n = 117) or histamine2-receptor antagonists (H2RAs, n = 37) for gastro-oesophageal reflux disease, and 76 nontreated subjects, with normal endoscopic findings (control group). Fasting blood samples were analysed for gastrin and CgA. Gastric biopsy specimens (oxyntic mucosa) were examined for histological evaluation of gastritis (Sydney classification) and of ECL cell hyperplasia (Solcia classification). RESULTS Serum CgA levels correlated positively with serum gastrin, following a quadratic function (r = 0.78, P < 0.0001). Elevated serum CgA values during long-term acid inhibition correlated with the presence and severity of fundic ECL cell hyperplasia. Multivariate analysis identified hypergastrinaemia (P < 0.0001), duration of acid inhibition (P < 0.0001), H. pylori infection (P = 0.008), ECL cell hyperplasia (P = 0.012), and body gland atrophy (P = 0.043) as independent predictors of elevated serum CgA. In subjects on long-term acid inhibition (n = 123), serum CgA was equally sensitive but more specific than serum gastrin for the detection of ECL cell hyperplasia (sensitivity, 91.3% for both; specificity, 73% vs. 43%, P < 0.0001). CONCLUSIONS During long-term gastric acid inhibition, serum CgA levels reflect the presence and severity of fundic ECL cell hyperplasia. Serum CgA is therefore a useful screening test for gastric ECL cell proliferative changes within this context.

Abstract
BACKGROUND Long-term acid suppression may accelerate the development of atrophic gastritis in Helicobacter pylori-positive subjects. The pathogenetic mechanism remains unclear. AIM To test the hypothesis that gastric double infection with H. pylori and non-H. pylori bacterial species-during acid suppression-may result in an enhanced inflammatory response, contributing to the development of atrophic gastritis. PATIENTS AND METHODS A consecutive series of patients with gastro-oesophageal reflux disease undergoing treatment with proton pump inhibitors (n=113) or histamine2-receptor antagonists (H2-RAs) (n=37), and 76 non-treated dyspeptic controls were investigated. Gastric mucosal H. pylori and non-H. pylori bacteria, histological gastritis, H. pylori serology, and circulating interleukin (IL)-1beta, IL-6, and IL-8 were examined. RESULTS Patients on acid suppression with either proton pump inhibitors or H2-RAs had a similar prevalence of H. pylori infection to the controls, but a higher prevalence of non-H. pylori bacteria (61% and 60% vs. 29%, P < 0.0001 and P < 0.002). Both the presence of H. pylori and non-H. pylori bacteria were independent risk factors of atrophic gastritis (antrum: relative risks (RRs), 10.1 and 5.07; corpus: RRs, 11.74 and 6.38). A simultaneous presence of H. pylori and non-H. pylori bacteria was associated with a markedly increased risk of atrophic gastritis (antrum: RR, 20.25; corpus: RR, 20.38), compatible with a synergistic effect. Furthermore, the simultaneous presence of both types of bacteria was associated with higher cytokine levels than in patients without any type of bacteria. This increase was also greater than in patients with H. pylori infection alone (P < 0.001, for both IL-1beta and IL-8). SUMMARY AND CONCLUSIONS H. pylori-positive patients on long-term acid inhibition displayed three features: non-H. pylori bacterial growth; increased cytokine levels; and a higher risk of atrophic gastritis. We suggest that double infection with H. pylori and non-H. pylori bacteria is a major factor in the development of atrophic gastritis during gastric acid inhibition.

Abstract
In the Western world, a sharp increase in the incidence of both Crohn's disease and ulcerative colitis was observed during the sixties and seventies, after which it reached a plateau at around 7 and 12 new cases per 100,000 inhabitants per year, respectively. Both chronic inflammatory bowel diseases usually commence between 15 and 30 years of age. Most patients have a normal life expectancy. A multifactorial model has been proposed to explain the pathogenesis, in which there seems to be an interaction between genetic predisposition, environmental factors and an altered immune response (occurring either after or because of the disease). Smoking is a clear risk factor in the development of Crohn's disease and it also negatively influences the clinical outcome. On the other hand, stopping smoking is a risk factor in the development of ulcerative colitis.

Abstract
Muscoloskeletal manifestations are the most common extraintestinal complications of inflammatory bowel disease. Wide ranges in prevalence have been reported, depending on the criteria used to define spondylarthropathy. In 1991, the European Spondylarthropathy Study Group developed classification criteria that included previously neglected cases of undifferentiated spondylarthropathies, which had been ignored in most of the oldest epidemiological studies on inflammatory bowel disease. The spectrum of muscoloskeletal manifestations in inflammatory bowel disease patients includes all of the clinical features of spondylarthropathies: peripheral arthritis, inflammatory spinal pain, dactylitis, enthesitis (Achilles tendinitis and plantar fasciitis), buttock pain and anterior chest wall pain. Radiological evidence of sacroiliitis is common but not obligatory. The articular manifestations begin either concomitantly or subsequent to the bowel disease; however, the onset of spinal disease often precedes the diagnosis of inflammatory bowel disease. The prevalence of the different muscoloskeletal manifestations is similar in ulcerative colitis and Crohn's disease. Symptoms usually disappear after proctocolectomy. The pathogenetic mechanisms that produce the muscoloskeletal manifestations in inflammatory bowel disease are unclear. Several arguments favour an important role of the intestinal mucosa in the development of spondylarthropathy. The natural history is characterized by periods of flares and remission; therefore, the efficacy of treatment is difficult to establish. Most patients respond to rest, physical therapy and nonsteroidal anti-inflammatory drugs, but these drugs may activate bowel disease. Sulphasalazine may be recommended in some patients. There is no indication for the systemic use of steroids.
