BACKGROUND Considering the poor prognosis of oesophageal adenocarcinoma (EAC), it is important to identify individuals at increased risk of developing EAC who may benefit from early detection and prevention strategies. We aimed to determine whether individuals with a positive family history of Barrett's oesophagus (BE) and EAC are at an increased risk of oesophageal neoplasia. METHODS In a multi-centre case-control study, BE patients with or without related oesophageal neoplasia and randomly selected population controls filled out a questionnaire to collect information on family history and other risk factors for BE and EAC. Positive family history was defined as having ≥1 first-degree relative with BE or EAC whose diagnosis was histologically confirmed in the Dutch nationwide histopathology database. FINDINGS We included 480 BE patients and 420 controls without BE who had a total of 6393 first-degree relatives. A pathologically confirmed positive family history was significantly higher in BE patients compared with controls (6.5% versus 0.9; p

BACKGROUND: It remains unclear whether urgent endoscopic retrograde cholangiopancreatography (ERCP) with biliary sphincterotomy improves the outcome of patients with gallstone pancreatitis without concomitant cholangitis. We did a randomised trial to compare urgent ERCP with sphincterotomy versus conservative treatment in patients with predicted severe acute gallstone pancreatitis.METHODS: In this multicentre, parallel-group, assessor-masked, randomised controlled superiority trial, patients with predicted severe (Acute Physiology and Chronic Health Evaluation II score ≥8, Imrie score ≥3, or C-reactive protein concentration >150 mg/L) gallstone pancreatitis without cholangitis were assessed for eligibility in 26 hospitals in the Netherlands. Patients were randomly assigned (1:1) by a web-based randomisation module with randomly varying block sizes to urgent ERCP with sphincterotomy (within 24 h after hospital presentation) or conservative treatment. The primary endpoint was a composite of mortality or major complications (new-onset persistent organ failure, cholangitis, bacteraemia, pneumonia, pancreatic necrosis, or pancreatic insufficiency) within 6 months of randomisation. Analysis was by intention to treat. This trial is registered with the ISRCTN registry, ISRCTN97372133.FINDINGS: Between Feb 28, 2013, and March 1, 2017, 232 patients were randomly assigned to urgent ERCP with sphincterotomy (n=118) or conservative treatment (n=114). One patient from each group was excluded from the final analysis because of cholangitis (urgent ERCP group) and chronic pancreatitis (conservative treatment group) at admission. The primary endpoint occurred in 45 (38%) of 117 patients in the urgent ERCP group and in 50 (44%) of 113 patients in the conservative treatment group (risk ratio [RR] 0·87, 95% CI 0·64-1·18; p=0·37). No relevant differences in the individual components of the primary endpoint were recorded between groups, apart from the occurrence of cholangitis (two [2%] of 117 in the urgent ERCP group vs 11 [10%] of 113 in the conservative treatment group; RR 0·18, 95% CI 0·04-0·78; p=0·010). Adverse events were reported in 87 (74%) of 118 patients in the urgent ERCP group versus 91 (80%) of 114 patients in the conservative treatment group.INTERPRETATION: In patients with predicted severe gallstone pancreatitis but without cholangitis, urgent ERCP with sphincterotomy did not reduce the composite endpoint of major complications or mortality, compared with conservative treatment. Our findings support a conservative strategy in patients with predicted severe acute gallstone pancreatitis with an ERCP indicated only in patients with cholangitis or persistent cholestasis.FUNDING: The Netherlands Organization for Health Research and Development, Fonds NutsOhra, and the Dutch Patient Organization for Pancreatic Diseases.

Contains fulltext : 238944.pdf (Publisher’s version ) (Closed access) IMPORTANCE: Diagnostic yield of upper gastrointestinal (GI) tract endoscopy for uninvestigated dyspepsia is low, and its clinical implications are limited. There is an unmet need for better strategies to reduce the volume of upper GI tract endoscopic procedures for dyspepsia. OBJECTIVE: To study the effectiveness of a web-based educational intervention as a tool to reduce upper GI tract endoscopy in uninvestigated dyspepsia. DESIGN, SETTING, AND PARTICIPANTS: This open-label, multicenter, randomized clinical trial enrolled participants between November 1, 2017, and March 31, 2019, with follow-up 52 weeks after randomization, at 4 teaching hospitals in the Netherlands. Participants included patients with uninvestigated dyspeptic symptoms who were referred for upper GI tract endoscopy by their general health care clinician without prior consultation of a gastroenterologist. A total of 119 patients, aged 18 to 69 years, were included. Patients were excluded if any of the following red flag symptoms were present: (indirect) signs of upper GI tract hemorrhage (hematemesis, melena, hematochezia, or anemia), unintentional weight loss of 5% or higher of normal body weight during a period of 6 to 12 months, persistent vomiting, dysphagia, or jaundice. INTERVENTIONS: Patients were randomly assigned (1:1) to education (intervention) or upper GI tract endoscopy (control). Education consisted of a self-managed web-based educational intervention, containing information on gastric function, dyspepsia, and upper GI tract endoscopy. MAIN OUTCOMES AND MEASURES: Difference in the proportion of upper GI tract endoscopy procedures between those who received access to the web-based educational intervention and those who did not at 12 weeks and 52 weeks after randomization, analyzed in the intention-to-treat population. Secondary outcomes included quality of life (Nepean Dyspepsia Index) and symptom severity (Patient Assessment of Gastrointestinal Disorders Symptom Severity Index) measured at baseline and 12 weeks. RESULTS: Of 119 patients included (median age, 48 years [interquartile range, 37-56 years]; 48 men [40%]), 62 were randomized to web-based education (intervention) and 57 to upper GI tract endoscopy (control). Significantly fewer patients compared with controls underwent upper GI tract endoscopy after using the web-based educational intervention: 24 (39%) vs 47 (82%) (relative risk, 0.46; 95% CI, 0.33-0.64; P

Background and Aims The COVID-19 risk and disease course in inflammatory bowel disease [IBD] patients remains uncertain. Therefore, we aimed to assess the clinical presentation, disease course, and outcomes of COVID-19 in IBD patients. Second, we determined COVID-19 incidences in IBD patients and compared this with the general population. Methods We conducted a multicentre, nationwide IBD cohort study in The Netherlands and identified patients with COVID-19. First, we assessed the COVID-19 disease course and outcomes. Second, we compared COVID-19 incidences between our IBD study cohort and the general Dutch population. Results We established an IBD cohort of 34 763 patients. COVID-19 was diagnosed in 100/34 763 patients [0.29%]; 20/100 of these patients [20%] had severe COVID-19 defined as admission to the intensive care unit, mechanical ventilation, and/or death. Hospitalisation occurred in 59/100 [59.0%] patients and 13/100 [13.0%] died. All patients who died had comorbidities and all but one were ≥65 years old. In line, we identified ≥1 comorbidity as an independent risk factor for hospitalisation (odds ratio [OR] 4.20, 95% confidence interval [CI] 1.58–11.17,; p = 0.004). Incidences of COVID-19 between the IBD study cohort and the general population were comparable (287.6 [95% CI 236.6–349.7] versus 333.0 [95% CI 329.3–336.7] per 100000 patients, respectively; p = 0.15). Conclusions Of 100 cases with IBD and COVID-19, 20% developed severe COVID-19, 59% were hospitalised and 13% died. A comparable COVID-19 risk was found between the IBD cohort [100/34 763 = 0.29%] and the general Dutch population. The presence of ≥1 comorbidities was an independent risk factor for hospitalisation due to COVID-19.

Contains fulltext : 220092.pdf (Publisher’s version ) (Open Access) Background: The Dutch guidelines for esophageal and gastro-esophageal junction (GEJ) cancer recommend discussion of patients by a multidisciplinary tumor board (MDT). Despite this recommendation, one previous study in the Netherlands suggested that therapeutic guidance was missing for palliative care of patients with esophageal cancer. The aim of the current study was therefore to assess the impact of an MDT discussion on initial palliative treatment and outcome of patients with esophageal or GEJ cancer.Material and methods: The population-based Netherlands Cancer Registry was used to identify patients treated for esophageal or GEJ cancer with palliative intent between 2010 and 2017 in 7 hospitals. We compared patients discussed by the MDT with patients not discussed by the MDT in a multivariate analysis. Primary outcome was type of initial palliative treatment. Secondary outcome was overall survival.Results: A total of 389/948 (41%) patients with esophageal or GEJ cancer were discussed by the MDT before initial palliative treatment. MDT discussion compared to non-MDT discussion was associated with more patients treated with palliative intent external beam radiotherapy (38% vs. 21%, OR 2.7 [95% CI 1.8-3.9]) and systemic therapy (30% vs. 23%, OR 1.6 [95% CI 1.0-2.5]), and fewer patients treated with stent placement (4% vs. 12%, OR 0.3 [95% CI 0.1-0.6]) and best supportive care alone (12% vs. 33%, OR 0.2 [95% CI 0.1-0.3]). MDT discussion was also associated with improved survival (169 days vs. 107 days, HR 1.3 [95% CI 1.1-1.6]).Conclusion: Our study shows that MDT discussion of patients with esophageal or GEJ cancer resulted in more patients treated with initial palliative radiotherapy and chemotherapy compared with patients not discussed by the MDT. Moreover, MDT discussion may have a positive effect on survival, highlighting the importance of MDT meetings at all stages of treatment.

Endoscopic dilation (ED) is still the mainstay of therapeutic management of benign esophageal strictures (BESs). This study aimed to establish risk factors for refractory BESs and assess long-term clinical outcomes of ED.We performed a retrospective study in 891 patients who underwent ED from 2003 to 2018 for BESs. We searched electronic medical records in 6 tertiary care centers in the Netherlands for data on clinical outcome of ED. Median follow-up was 39 months. The primary endpoint was risk factors for refractory BESs, defined as factors associated with an increased number of ED sessions during follow-up. Secondary endpoints were time from first to last ED session and adverse events.Dilation up to 13 to 15 mm was associated with a higher number of ED sessions than dilation up to 16 to 18 mm (5.0 vs 4.1; hazard ratio [HR], 1.4; P = .001). Compared with peptic strictures, anastomotic (4.9 vs 3.6; HR, 2.1; P .001), radiation (5.0 vs 3.6; HR, 3.0; P .001), caustic (7.2 vs 3.6; HR, 2.7; P .001), and postendotherapy (3.9 vs 3.6; HR, 1.8; P = .005) strictures were associated with a higher number of ED sessions. After 1 year of follow-up, the proportions of patients who remained free of ED was 75% in anastomotic, 71% in radiation, 70% in peptic, 83% in postendotherapy, and 62% in caustic strictures. Esophageal perforation occurred in 23 ED sessions (.4%) in 22 patients (2.4%).More than 60% of patients with BESs remain free of ED after 1 year of follow-up. Because dilation up to 16 to 18 mm diameter was associated with fewer ED sessions during follow-up, we suggest that clinicians should consider dilation up to at least 16 mm to reduce the number of ED sessions in these patients.

Background Tools for patient identification to safely cease anti-TNF therapy in Crohn’s disease (CD) patients are urgently needed. After an individual participant data meta-analysis (IPD-MA) a predictive diagnostic tool has been developed for cessation of anti-TNF therapy in CD. This study aims to validate this tool. Methods A retrospective study was conducted, in 16 Dutch Hospitals, of CD patients in whom anti-TNF therapy was ceased. Inclusion criteria were anti-TNF therapy use >6 months, start of anti-TNF therapy due to luminal CD and remission as an indication for cessation. Collected baseline demographic, clinical, biochemical, treatment and imaging data were included; age, gender, smoking, Montreal classification, disease- and remission duration, history of surgery, type of anti-TNF medication, previous or concomitant immunosuppressant, thiopurines level, previous anti-TNF therapy, anti-TNF therapy duration, haemoglobin, leukocytes, thrombocytes, albumin, C-reactive protein, anti-TNF serum concentration, anti-infliximab/adalimumab antibodies, remission at MRI/endoscopy, additional stop reason other than remission. The primary outcome was documented relapse of CD that necessitated (re)introduction of biologicals, corticosteroids or immune-suppressants or surgery. Results A total of 523 CD patients (333 females (63%), median age 40 years (IQR 32 – 53)) were included. 293 (56%) patients experienced a relapse after anti-TNF cessation after a median follow-up of 30.2 months (IQR 15–51). The relapse rate was 33% (95% CI 31–34) and 53% (95% CI 52–53) after 1 and 2 years, respectively. The discriminative ability of the prediction model in this external validation cohort (Table 1) equalled that of a previous IPD-MA with a C-statistic of 0.59. An update of the model with faecal calprotectin resulted in a C-statistic of 0.60 [0.55–0.63] and a reported calibration slope of 0.69. Conclusion A previously developed predictive diagnostic tool to safely cease anti-TNF therapy in CD has been validated, however, showed moderate performance in this external cohort. A further update of the model with biochemical and histological data is necessary to improve our ability to adequately select patients for cessation of anti-TNF therapy and is currently being performed.

Background In current clinical practice, patients with inflammatory bowel disease (IBD) treated with originator infliximab (IFX) have been or are being switched to biosimilar infliximab (CT-P13) because of lower costs and seemingly similar effectiveness of biosimilars. Over a one-year follow-up, 7%-26% of the patients discontinue CT-P13 treatment. Common reasons for CT-P13 discontinuation are (subjective) loss of response or adverse events. As a result of these newly experienced symptoms, patients are occasionally switched back to treatment with originator IFX. However, not much is currently known regarding reverse switching to originator IFX. We aimed to assess the prevalence of and the specific reasons for reverse switching to originator infliximab within 52-weeks after an initial conversion from originator infliximab to CT-P13 in patients with IBD. Additionally, we evaluated whether reinitiating originator infliximab led to the desired favourable effect and sustained infliximab use. Methods In this retrospective, multicentre cohort study, data of IBD patients from eight hospitals in the Netherlands were collected. Adult patients with IBD were eligible for inclusion if they were switched from infliximab originator to CT-P13 and had a follow-up time of at least 52 weeks after initial conversion. Reasons for re-switching were categorised into adverse events or loss of response on the biosimilar. Drug survival was analysed with a time-varying Cox proportional hazards model. Results A total of 684 patients with IBD were switched (516 Crohn’s disease, 168 ulcerative colitis). Reverse switching was seen in 74 (10.8%) patients after a median of 140 days (IQR 86–231). Reverse switchers were more often females (70.3% vs. 49.7%, p < 0.001) and had shorter originator treatment (4.0 [IQR 2.6–6.5] vs. 5.2 [IQR 3.0–7.5] years, p = 0.037) than those who stayed on CT-P13. A total of 105 symptoms for switching were reported. IBD-like symptoms (25.7%) and dermatological symptoms (21.9%) were the most common. Four patients had objectified loss of response. All regained response after switching back. IBD-like symptoms and dermatological symptoms were reversible in 74.1% and 87%, respectively. Overall reversibility of symptoms was 73.3%. Cox proportional hazards model with CT-P13/originator infliximab as time-varying covariate, yielded no difference in survival risk (hazard ratio 1.23, 95% CI 0.65–2.33). Conclusion Switching back to originator infliximab seems effective in patients with IBD, who experience adverse effects or loss of response after switching from originator to CT-P13. Switching patients back to originator infliximab might, therefore, be justified in case patients experience new side effects or loss of response after switching to CT-P13.

IntroductionIdiopathic acute pancreatitis (IAP) remains a dilemma for physicians as it is uncertain whether patients with IAP may actually have an occult aetiology. It is unclear to what extent additional diagnostic modalities such as endoscopic ultrasonography (EUS) are warranted after a first episode of IAP in order to uncover this aetiology. Failure to timely determine treatable aetiologies delays appropriate treatment and might subsequently cause recurrence of acute pancreatitis. Therefore, the aim of the Pancreatitis of Idiopathic origin: Clinical added value of endoscopic UltraSonography (PICUS) Study is to determine the value of routine EUS in determining the aetiology of pancreatitis in patients with a first episode of IAP.Methods and analysisPICUS is designed as a multicentre prospective cohort study of 106 patients with a first episode of IAP after complete standard diagnostic work-up, in whom a diagnostic EUS will be performed. Standard diagnostic work-up will include a complete personal and family history, laboratory tests including serum alanine aminotransferase, calcium and triglyceride levels and imaging by transabdominal ultrasound, magnetic resonance imaging or magnetic resonance cholangiopancreaticography after clinical recovery from the acute pancreatitis episode. The primary outcome measure is detection of aetiology by EUS. Secondary outcome measures include pancreatitis recurrence rate, severity of recurrent pancreatitis, readmission, additional interventions, complications, length of hospital stay, quality of life, mortality and costs, during a follow-up period of 12 months.Ethics and disseminationPICUS is conducted according to the Declaration of Helsinki and Guideline for Good Clinical Practice. Five medical ethics review committees assessed PICUS (Medical Ethics Review Committee of Academic Medical Center, University Medical Center Utrecht, Radboud University Medical Center, Erasmus Medical Center and Maastricht University Medical Center). The results will be submitted for publication in an international peer-reviewed journal.Trial registration numberNetherlands Trial Registry (NL7066). Prospectively registered.

Contains fulltext : 195713.pdf (Publisher’s version ) (Open Access) BACKGROUND: Azathioprine (AZA) and mercaptopurine (MP) are the cornerstone of steroid-sparing strategies in autoimmune hepatitis (AIH). Up to 20% of patients do not tolerate or respond to these regimens. AIM: To evaluate retrospectively the tolerability and efficacy of tioguanine (thioguanine) (TG) therapy in selected patients with AIH and AIH variant syndromes. METHODS: Records of 52 patients who received TG therapy were retrieved from nine hospitals in the Netherlands. Indications for TG treatment were intolerable side effects on AZA or MP (n = 38), insufficient response (n = 11) or first-line treatment (n = 3). Treatment efficacy was defined as normalisation of serum aminotransferases and serum immunoglobulin G. RESULTS: No serious adverse events occurred in patients treated with TG during a median follow-up of 18 months (range 1-194). Treatment was well tolerated in 41 patients (79%), whereas four had tolerable (8%) and seven (13%) intolerable side effects. Thirty-eight patients were treated with TG after intolerable side effects on AZA or MP; 29 patients continued TG therapy of whom 24 (83%) achieved complete biochemical remission, four (14%) had incomplete and one (3%) had no response; nine discontinued treatment. Seven of 11 patients with insufficient response to AZA or MP were responsive to TG, three with complete and four with incomplete biochemical remission; four discontinued due to intolerance (n = 2) and non-response (n = 2). TG was effective in all AIH patients as first-line maintenance treatment. CONCLUSION: In our retrospective review of TG therapy in selected patients with AIH or AIH variants who previously failed on AZA or MP, TG appeared tolerable with biochemical efficacy.

Background: Chronic pancreatitis is a complex disease with many unanswered questions regarding the natural history and therapy. Prospective longitudinal studies with long-term follow-up are warranted.Methods: The Dutch Chronic Pancreatitis Registry (CARE) is a nationwide registry aimed at prospective evaluation and follow-up of patients with chronic pancreatitis. All patients with (suspected) chronic or recurrent pancreatitis are eligible for CARE. Patients are followed-up by yearly questionnaires and review of medical records. Study outcomes are pain, disease complications, quality of life, and pancreatic function. The target sample size was set at 500 for the first year and 1000 patients within 3 years.Results: A total of 1218 patients were included from February 2010 until June 2013 by 76 participating surgeons and gastroenterologist from 33 hospitals. Participation rate was 90% of eligible patients. Eight academic centers included 761 (62%) patients, while 25 community hospitals included 457 (38%). Patient centered outcomes were assessed by yearly questionnaires, which had a response rate of 85 and 82% for year 1 and 2, respectively. The median age of patients was 58 years, 814 (67%) were male, and 38% had symptoms for less than 5 years.Discussion: The CARE registry has successfully recruited over 1200 patients with chronic and recurrent pancreatitis in about 3 years. The defined inclusion criteria ensure patients are included at an early disease stage. Participation and compliance rates are high. CARE offers a unique opportunity with sufficient power to investigate many clinical questions regarding natural course, complications, and efficacy and timing of treatment strategies.

Objective For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.Patients and methods This randomized multicenter trial included 219 patients who were randomized to receive plastic stent (n = 73) or SEMS [uncovered (n = 75) and covered (n = 71); n = 146] placement. HRQoL was assessed with two general questionnaires (EQ-5D-3L and QLQ-C30) and one disease-specific questionnaire (PAN-26). Scores were analyzed using linear mixed model regression and included all patients with baseline and at least one follow-up measurement.Results HRQoL data were available in 140 of 219 patients (64%); 71 patients (32%) declined participation and in eight patients (4%) only baseline questionnaires were available. On the QLQ-C30, the interaction between follow-up time and type of stent was significantly different on two of five functional scales [physical functioning (P = 0.004) and emotional functioning (P = 0.01)] in favor of patients with a SEMS. In addition, patients with SEMS reported significantly less frequent symptoms of fatigue (P = 0.01), loss of appetite (P = 0.02), and nausea and vomiting (0.04) over time. The EQ-VAS score decreased with time in both treatment groups, indicating a statistically significant decrease in HRQoL over time.Conclusion In patients with inoperable malignant extrahepatic bile duct obstruction, SEMS placement results in better scores for general and disease-specific HRQoL over time compared with plastic stent placement.

Contains fulltext : 169929.pdf (Publisher’s version ) (Closed access) OBJECTIVE: Proton pump inhibitors (PPIs) are effective drugs for the treatment of gastric acid-related disorders. Serious adverse events are rare for PPIs, but recent data suggest that PPIs cause hypomagnesemia. The aim of this study was to estimate the frequency of PPI-induced hypomagnesemia and to define the risk factors for its development. MATERIALS AND METHODS: A total of 133 chronic users of PPIs were enrolled and patients were distinguished on the basis of their serum Mg concentrations. Common single nucleotide polymorphisms (SNPs) in the candidate gene, transient receptor potential melastatin type 6 (TRPM6), were screened. RESULTS: Seventeen out of 133 patients had PPI-induced hypomagnesemia. The duration of PPI use was longer in those with hypomagnesemia (7.7 vs. 5.2 years). Two common SNPs in TRPM6 (rs3750425 and rs2274924) increased the risk for PPI-induced hypomagnesemia by 5.8-fold. CONCLUSION: We found hypomagnesemia in 13% of PPI users. SNPs in TRPM6 drive the risk of developing hypomagnesemia during chronic PPI use.

Barrett's esophagus, with gastroesophageal reflux disease and obesity as risk factors, predisposes to esophageal adenocarcinoma (EAC). Recently a British genome wide association study identified two Barrett's esophagus susceptibility loci mapping within the major histocompatibility complex (MHC; rs9257809) and closely to the Forkhead-F1 (FOXF1; rs9936833) coding gene. An interesting issue is whether polymorphisms associated with Barrett's esophagus, are also implicated in esophageal carcinoma (EC), and more specifically EAC genesis. Assessing the individual genetic susceptibility can help identify high risk patients more prone to benefit from surveillance programs. Our hypothesis: Barrett associated MHC and FOXF1 variants modify EC risk in Caucasians. In a Dutch case-control study, 431 patients with EC and 605 healthy controls were included. Polymorphisms at chromosomes 6p21 (MHC) and 16q24 (FOXF1) were determined by means of real-time polymerase chain reaction (RT-PCR). Logistic regression analysis was used to calculate odds ratios with 95% confidence intervals. The FOXF1 rs9936833 variant C allele was associated with an increased EAC susceptibility; OR, [95% CI]; 1.21, [0.99-1.47]. A sex-stratified analysis revealed a similar association in males; 1.24 [1.00-1.55]. The variant MHC rs9257809 G allele as well as the MHC heterozygous AG genotype significantly increased ESCC risk; 1.76 [1.16-2.66] and 1.74 [1.08-2.80], respectively. Sex-stratification showed that the variant G allele was especially present in female patients; 2.32 [1.04-5.20]. In conclusion, this study provides evidence that MHC rs9257809 and FOXF1 rs9936833 variants, associated with Barrett's esophagus, also increase ESCC and EAC susceptibility in Caucasians. FOX proteins are transcription factors involved in organogenesis of the GI tract, while MHC haplotypes are strongly associated with smoking behavior, a crucial risk factor for ESCC. Assessing the individual genetic susceptibility can help identify high risk patients more prone to benefit from (Barrett) surveillance programs.

Background Acute pancreatitis is mostly caused by gallstones or sludge. Early decompression of the biliary tree by endoscopic retrograde cholangiography (ERC) with sphincterotomy may improve outcome in these patients. Whereas current guidelines recommend early ERC in patients with concomitant cholangitis, early ERC is not recommended in patients with mild biliary pancreatitis. Evidence on the role of routine early ERC with endoscopic sphincterotomy in patients without cholangitis but with biliary pancreatitis at high risk for complications is lacking. We hypothesize that early ERC with sphincterotomy improves outcome in these patients. Methods/Design The APEC trial is a randomized controlled, parallel group, superiority multicenter trial. Within 24 hours after presentation to the emergency department, patients with biliary pancreatitis without cholangitis and at high risk for complications, based on an Acute Physiology and Chronic Health Evaluation (APACHE-II) score of 8 or greater, Modified Glasgow score of 3 or greater, or serum C-reactive protein above 150 mg/L, will be randomized. In 27 hospitals of the Dutch Pancreatitis Study Group, 232 patients will be allocated to early ERC with sphincterotomy or to conservative treatment. The primary endpoint is a composite of major complications (that is, organ failure, pancreatic necrosis, pneumonia, bacteremia, cholangitis, pancreatic endocrine, or exocrine insufficiency) or death within 180 days after randomization. Secondary endpoints include ERC-related complications, infected necrotizing pancreatitis, length of hospital stay and an economical evaluation. Discussion The APEC trial investigates whether an early ERC with sphincterotomy reduces the composite endpoint of major complications or death compared with conservative treatment in patients with biliary pancreatitis at high risk of complications.

Contains fulltext : 172861.pdf (Publisher’s version ) (Closed access) BACKGROUND: Proton pump inhibitors (PPI) are among the most widely prescribed drugs to treat gastric acid-related disorders. PPI-induced hypomagnesaemia, a defect in intestinal absorption of Mg(2+) , can be a severe side effect of chronic PPI use. AIM: To restore serum Mg(2+) concentrations in PPI-induced hypomagnesaemia patients by dietary supplementation with inulin fibres. METHODS: Eleven patients with PPI-induced hypomagnesaemia and 10 controls were treated with inulin (20 g/day). Each trial consisted of two cycles of 14-day inulin treatment followed by a washout period of 14 days. Patients continued to use their PPI. Serum Mg(2+) levels served as the primary endpoint. RESULTS: Inulin significantly enhanced serum Mg(2+) levels from 0.60 to 0.68 mmol/L in PPI-induced hypomagnesaemia patients, and from 0.84 to 0.93 mmol/L in controls. As a consequence 24 h urinary Mg(2+) excretion was significantly increased in patients with PPI-induced hypomagnesaemia (0.3-2.2 mmol/day). Symptoms related to hypomagnesaemia, including muscle cramps and paraesthesia, were reduced during intervention with inulin. CONCLUSION: Inulin increases serum Mg(2+) concentrations under PPI maintenance in patients with PPI-induced hypomagnesaemia. 01 juni 2016

Item does not contain fulltext OBJECTIVES: Electromagnetic (EM)-guided bedside placement of nasoenteral feeding tubes by nurses may improve efficiency and reduce patient discomfort and costs compared with endoscopic placement by gastroenterologists. However, evidence supporting this task shift from gastroenterologists to nurses is limited. We aimed to compare the effectiveness of EM-guided and endoscopic nasoenteral feeding tube placement. METHODS: We performed a multicenter randomized controlled non-inferiority trial in 154 adult patients who required nasoenteral feeding and were admitted to gastrointestinal surgical wards in five Dutch hospitals. Patients were randomly assigned (1:1) to undergo EM-guided or endoscopic nasoenteral feeding tube placement. The primary end point was the need for reinsertion of the feeding tube (e.g., after failed initial placement or owing to tube-related complications) with a prespecified non-inferiority margin of 10%. RESULTS: Reinsertion was required in 29 (36%) of the 80 patients in the EM-guided group and 31 (42%) of the 74 patients in the endoscopy group (absolute risk difference -6%, upper limit of one-sided 95% confidence interval 7%; P for non-inferiority=0.022). No differences were noted in success and complication rates. In the EM-guided group, there was a reduced time to start of feeding (424 vs. 535 min, P=0.001). Although the level of discomfort was higher in the EM-guided group (Visual Analog Scale (VAS) 3.9 vs. 2.0, P=0.009), EM-guided placement received higher recommendation scores (VAS 8.2 vs. 5.5, P=0.008). CONCLUSIONS: EM-guided bedside placement of nasoenteral feeding tubes by nurses was non-inferior to endoscopic placement by gastroenterologists in surgical patients and may be considered the preferred technique for nasoenteral feeding tube placement.

Contains fulltext : 108111.pdf (Publisher’s version ) (Open Access) Esophageal cancer (EC) has a globally increasing incidence with poor curative treatment options and survival rates. Environmental and dietary factors have crucial roles in esophageal carcinogenesis. Polymorphisms in the UGT genes, a superfamily of enzymes essential for the detoxification of carcinogens, may alter enzyme activity and subsequently may play a role in EC etiology. Rather than solely establishing differences in genotype distribution, we investigated whether functional polymorphisms in UGT genes that can predict enzyme activity in vivo, may influence EC risk. A case-control study including 351 Caucasian EC patients and 592 Caucasian controls was conducted and polymorphisms in seven UGT genes were determined, using the polymerase chain reaction. On the basis of allelic in vitro enzyme activity measurements, genotypes were categorized according to their predicted in vivo enzyme activity into high, medium and low categories. Predicted enzyme activity groups were combined and compared between patients and controls. The UGT1A1 and UGT1A8 predicted high enzyme activity genotypes were significantly more (OR=1.62; 95% CI, 1.02-2.56) and less frequent (OR=0.36; 95% CI, 0.15-0.84) among patients with esophageal squamous cell carcinoma (ESCC), respectively. High (OR=0.42; 95% CI, 0.22-0.84) and medium (OR=0.25; 95% CI, 0.12-0.52) activity UGT2B4 genotypes were significantly less often present in ESCC patients. No association was detected between UGT genotypes and esophageal adenocarcinoma (EAC) risk. Polymorphisms in UGT genes, resulting in altered enzyme activity genotypes, do not seem modifiers of EAC risk. However, the predicted high activity UGT1A1 genotype, associated with low serum levels of the antioxidant bilirubin, was associated with an increased ESCC risk. The UGT1A8 and UGT2B4 genotypes associated with decreased predicted enzyme activities, were significantly associated with an increased risk of ESCC, probably by a decreased detoxification of carcinogens. 01 juni 2012

Background Self-expanding metal stents (SEMS) are known to have a significantly higher patency rate than plastic stents. We aimed to identify prognostic factors, besides stent type, for stent patency and to develop a score model that could further aid in guiding stent choice for the palliation of a malignant biliary stricture. Methods A retrospective multicenter study was conducted. Data on consecutive patients who had a stent placed between January 2002 and July 2009 were collected. Cumulative stent occlusion rates were analyzed by Kaplan-Meier curves and log rank testing, and prognostic factors were assessed by Cox regression analysis. Results A total of 690 stents (512 plastic stents, 174 SEMS) were endoscopically placed in 390 patients. At 8 weeks, stent occlusion had occurred in 32% of the plastic stents and 11% of the SEMS. Multivariate analysis indicated that plastic stents (hazard ratio [HR] 2.5, 95% confidence interval [CI] 1.9-3.5), a tight stricture requiring preceding dilation (HR 1.8, 95% CI 1.3-2.5), and a high initial bilirubin level (>50 mu mol/L (HR 1.3, 95% CI 1.0-1.7) were independently associated with an increased risk of stent occlusion. A score model based on these 3 factors was able to distinguish between stent procedures with a relatively high and low risk of stent occlusion (median 14 vs. 26 weeks, respectively). Conclusion Besides plastic stents, stricture severity requiring preceding dilation, and initial higher bilirubin level were associated with a shorter period of stent patency. A simple score model based on these factors was able to predict stent occlusion and may aid in choosing the most appropriate stent type in individual patients.

OJECTIVES: The risk for inflammatory bowel disease (IBD)-related colorectal cancer (CRC) remains a matter of debate. Initial reports mainly originate from tertiary referral centers, and conflict with more recent studies. Overall, epidemiology of IBD-related CRC is relevant to strengthen the basis of surveillance guidelines. We performed a nationwide nested case-control study to assess the risk for IBD-related CRC and associated prognostic factors in general hospitals. METHODS: IBD patients diagnosed with CRC between January 1990 and July 2006 in 78 Dutch general hospitals were identified as cases, using a nationwide automated pathology database. Control IBD patients without CRC were randomly selected. Clinical data were collected from detailed chart review. Poisson regression analysis was used for univariable and multivariable analyses. RESULTS: A total of 173 cases were identified through pathology and chart review and compared with 393 controls. The incidence rate of IBD-related CRC was 0.04%. Risk factors for IBD-related CRC were older age, concomitant primary sclerosing cholangitis (PSC, relative ratio (RR) per year duration 1.05; 95% confidence interval (CI) 1.01-1.10), pseudopolyps (RR 1.92; 95% CI 1.28-2.88), and duration of IBD (RR per year 1.04; 95% CI 1.02-1.05). Using immunosuppressive therapy (odds ratio (OR) 0.3; 95% CI 0.16-0.56, P < 0.001) or anti-tumor necrosis factor (TNF) (OR 0.09; 95% CI 0.01-0.68, P < 0.02) was protective. CONCLUSIONS: We found a limited risk for developing IBD-related CRC in The Netherlands. Age, duration of PSC and IBD, concomitant pseudopolyps, and use immunosuppressives or anti-TNF were strong prognostic factors in general hospitals.

Contains fulltext : 70440.pdf (Publisher’s version ) (Closed access) BACKGROUND & AIMS: Antidepressants could be effective in the treatment of functional gastrointestinal disorders through their anticholinergic and pain-modulating effects. Previous studies with these drugs lacked sufficient power and were predominantly conducted in patients with irritable bowel syndrome. This study aimed to assess the effectiveness of the serotonin and norepinephrine reuptake inhibitor venlafaxine in patients with functional dyspepsia. METHODS: This was a multi-center, randomized, double-blind, placebo-controlled trial. Participants had persistent dyspeptic symptoms and underwent upper gastrointestinal endoscopy in a secondary care hospital to exclude organic abnormalities. They were randomly assigned to receive 8 weeks of treatment with either venlafaxine XR (2 weeks 75 mg once daily, 4 weeks 150 mg once daily, and 2 weeks 75 mg once daily) or placebo. Symptoms, health-related quality of life, anxiety, and depression were assessed before and at 4, 8, 12, and 20 weeks after inclusion. RESULTS: One hundred sixty patients were randomized; 56% and 73% of participants completed treatment with venlafaxine or placebo, respectively, according to protocol. There was no difference in proportions of symptom-free patients after 8 weeks of treatment or at 20 weeks after inclusion, with venlafaxine in comparison to placebo (37% and 39%, respectively; odds ratio [OR], 0.8; 95% confidence interval [CI], 0.3-2.1; and 42% and 41%, respectively; OR, 3.1; 95% CI, 0.9-12.6). Per-protocol analysis did not reveal any differences between venlafaxine and placebo either (38% and 39% symptom-free, respectively; OR, 1.0; 95% CI, 0.4-2.4 at 8 weeks). CONCLUSIONS: Treatment with the selective serotonin and norepinephrine reuptake inhibitor venlafaxine is not more effective than placebo in patients with functional dyspepsia.

Background/Aim: Over the past 15 years, there were considerable changes in factors associated with the development and treatment of upper gastrointestinal symptoms, of which the introduction of proton pump inhibitors and Helicobacter pylori eradication in guidelines for treatment of patients with dyspepsia are the most prominent: findings at open-access upper gastrointestinal endoscopy have not been evaluated properly ever since. This study aims to compare the current prevalence of upper gastrointestinal endoscopic findings to the prevalence 15 years ago. Methods: Data about endoscopic findings of consecutive patients for the first time referred for open-access upper gastrointestinal endoscopy between January 2002 and December 2004 was collected from medical files. The prevalence of each specific finding was compared with data described in three historical populations about 15 years ago. Results: The current and historical study population consisted of 1,286 and 3,062 subjects, respectively. The prevalence of peptic ulcer disease and duodenitis significantly decreased by 12.6% (95% CI: 14.5–10.7) and 2.9% (95% CI: 4.5–1.3), respectively. On the other hand, the prevalence of reflux esophagitis and Barrett’s esophagus both significantly increased by 6.9% (95% CI: 4.2–9.6) and 2.1% (95% CI: 0.8–4.4), respectively. Conclusions: Compared to 15 years ago, the prevalence of specific findings at open-access upper gastrointestinal endoscopy has changed considerably.

Contains fulltext : 52156.pdf (Publisher’s version ) (Closed access) BACKGROUND AND STUDY AIM: The total number of upper gastrointestinal endoscopies is increasing, and despite guidelines for endoscopy referral for general practitioners, the proportion of patients found to have no endoscopic abnormalities is still up to 60% (and increasing). The aim of this study was to assess the association between general practitioners' referral indications and endoscopic findings. PATIENTS AND METHODS: General practitioners of patients referred for an open-access endoscopy between January 2002 and December 2004 were asked to specify the reason for referral on a specially designed form. The relative frequency of patients actually having an endoscopic abnormality was assessed for each referral indication. RESULTS: A total of 1298 people were included in the study. A relevant endoscopic abnormality was found in 48% of patients. Patients with an endoscopic abnormality were not more often referred with "alarm" symptoms or failure of empirical treatment than patients without an abnormal endoscopic finding (31% with an endoscopic abnormality vs. 30% without an endoscopic abnormality had alarm symptoms; 57% of people in both groups experienced failure of empirical treatment). Referral with alarm symptoms had a positive predictive value of 4% for cancer (prevalence 2%; P < 0.01), and referral with reflux-like symptoms had a positive predictive value of 33% for finding reflux esophagitis (prevalence 22%; P < 0.01). CONCLUSIONS: General practitioners' referral indications for open-access endoscopy did not add any relevant predictive value for endoscopic findings in comparison with what might have been expected from overall prevalence. Only alarm symptoms slightly increased the probability of finding cancer and only reflux-like symptoms slightly increased the probability of finding reflux esophagitis.

Background Gastroparesis is common in surgical patients and frequently leads to the need for enteral tube feeding. Nasoenteral feeding tubes are usually placed endoscopically by gastroenterologists, but this procedure is relatively cumbersome for patients and labor-intensive for hospital staff. Electromagnetic (EM) guided bedside placement of nasoenteral feeding tubes by nurses may reduce patient discomfort, workload and costs, but randomized studies are lacking, especially in surgical patients. We hypothesize that EM guided bedside placement of nasoenteral feeding tubes is at least as effective as endoscopic placement in surgical patients, at lower costs. Methods/Design The CORE trial is an investigator-initiated, parallel-group, pragmatic, multicenter randomized controlled non-inferiority trial. A total of 154 patients admitted to gastrointestinal surgical wards in five hospitals, requiring nasoenteral feeding, will be randomly allocated to undergo EM guided or endoscopic nasoenteral feeding tube placement. Primary outcome is reinsertion of the feeding tube, defined as the insertion of an endoscope or tube in the nose/mouth and esophagus for (re)placement of the feeding tube (e.g. after failed initial placement or dislodgement or blockage of the tube). Secondary outcomes include patient-reported outcomes, costs and tube (placement) related complications. Discussion The CORE trial is designed to generate evidence on the effectiveness of EM guided placement of nasoenteral feeding tubes in surgical patients and the impact on costs as compared to endoscopic placement. The trial potentially offers a strong argument for wider implementation of this technique as method of choice for placement of nasoenteral feeding tubes.

BACKGROUND: Little is known about the variation in health-related quality of life among patients with different presentations of gastrointestinal symptoms. AIM: To study the association between health-related quality of life and presentations of gastrointestinal symptoms. METHODS: Health-related quality of life and demographic information was obtained from 873 patients referred to the hospital for endoscopy, using a questionnaire. RESULTS: A total of 436 patients (50%) reported predominantly upper gastrointestinal symptoms, 344 (39%) predominantly lower symptoms, and 93 (11%) patients reported both upper and lower symptoms. Patients with mild, moderate and severe symptoms, reported mean scores on a 100-point visual analogue scale (95% CI) of 90 (79-100), 75 (64-86) and 64 (53-76), respectively (P < 0.001). Mean visual analogue scale scores (95% CI) almost linearly declined from 81 (77-85) to 49 (46-52) for those with one to those with more than eight symptoms. Patients who reported upper gastrointestinal symptoms and in particular epigastric pain, bloating and vomiting had significantly impaired health status in comparison to patients without these symptoms (P < 0.05). CONCLUSIONS: Severity of gastrointestinal symptoms is the most important factor in affecting health status, followed by the numbers and type of gastrointestinal symptoms.

Contains fulltext : 125778.pdf (Publisher’s version ) (Closed access) Esophageal cancer (EC), mainly consisting of squamous cell carcinoma (ESCC) in the Eastern world and adenocarcinoma (EAC) in the Western world, is strongly associated with dietary factors such as alcohol use. We aimed to clarify the modifying role in EC etiology in Caucasians of functional genotypes in alcohol-metabolizing enzymes. In all, 351 Caucasian patients with EC and 430 matched controls were included and polymorphisms in CYP2E1, ADH and near ALDH2 genes were determined. In contrast to the results on ESCC in mainly Asian studies, we found that functional genotypes of alcohol-metabolizing enzymes were not significantly associated with EAC or ESCC in an European population.

Diet and lifestyle influence colorectal adenoma recurrence. The role of dietary supplement use in colorectal adenoma recurrence remains controversial. In this prospective cohort study, we examined the association between dietary supplement use, total colorectal adenoma recurrence and advanced adenoma recurrence. Colorectal adenoma cases (n = 565) from a former case-control study, recruited between 1995 and 2002, were prospectively followed until 2008. Adenomas with a diameter of ≥1 cm and/or (tubulo)villous histology and/or with high grade dysplasia and/or ≥3 adenomas detected at the same colonic examination were considered advanced adenomas. Hazard ratios (HRs) and 95% confidence intervals (CIs) for dietary supplement users (use of any supplement during the past year) compared to nonusers and colorectal adenoma recurrence were calculated using stratified Cox proportional hazard models for counting processes and were adjusted for age, sex, educational level and number of colonoscopies during follow-up. Robust sandwich covariance estimation was used to adjust for the within subject correlation. A number of 165 out of 565 adenoma patients had at least one colorectal adenoma recurrence during a median person-time of 5.4 years and of these, 37 patients had at least one advanced adenoma. One-third of the total study population (n = 203) used a dietary supplement. Compared to no use, dietary supplement use was neither statistically significantly associated with total colorectal adenoma recurrence (HR = 1.03; 95% CI 0.79-1.34) nor with recurrent advanced adenomas (HR = 1.59; 95% CI 0.88-2.87). This prospective cohort study did not suggest an association between dietary supplement use and colorectal adenoma recurrence. What's new? People take vitamins and other dietary supplements for many reasons, but could your supplements be harmful? Heine-Bröring et al. investigated the effects of dietary supplements on colorectal adenomas, to better advise those at risk. Colorectal cancer is one of the most common types of cancer in the Western world, and one red flag for clinicians is the presence of colorectal adenomas. Patients who develop these asymptomatic growths have an increased risk of colorectal cancer. As more and more people have begun taking multivitamin supplements, it is important to know how to advise patients with recurrent colorectal adenomas regarding dietary supplements. The researchers conducted a cohort study, including 203 dietary supplement users and 362 nonusers, and looked at the relative frequency of colorectal adenomas in each group. Their results showed that taking dietary supplements such as vitamin C, calcium, or multivitamins did not reduce or increase a person's risk of colorectal adenoma recurrence. Use of B-vitamin supplements, however, were associated with an increase in total recurrent colorectal adenomas, but not with recurrent adenomas that showed advanced pathology. © 2012 UICC.

Contains fulltext : 118871.pdf (Publisher’s version ) (Open Access) BACKGROUND: Identifying and monitoring high-risk patients can aid the prevention of esophageal cancer (EC). The interaction of environmental risk factor exposure and genetic susceptibility may contribute to the etiology of EC. Biotransformation enzymes such as Glutathione S-Transferases (GSTs ) detoxify mutagenic and genotoxic compounds and therefore control the rate of detoxification of carcinogens. Functional polymorphisms in the genes coding for GSTs alter their enzyme activity in vitro, and were reported to modify EC risk in Asians. We hypothesized that altered enzyme activity GST genotypes influence the susceptibility for esophageal adeno- (EAC) and squamous cell carcinoma (ESCC) in Caucasians. METHODS: We performed a case-control study including 440 Caucasian patients with EC and 592 healthy Caucasian controls matched for age and sex. Functional polymorphisms were selected and genotypes were determined in GST classes Alpha, Mu, Theta and Pi by means of polymerase chain reaction. Genotypes were classified into predicted high, intermediate and low enzyme activity categories based on in vitro activity data. The distribution of the activity genotypes were compared between patients with EAC or ESCC, and controls. Odds ratios (OR) with 95% confidence intervals (CI) were calculated by logistic regression analyses. Gene-gene interactions were tested and for comparison purposes, the predicted low and intermediate activity genotypes were combined. Genotypes with similar risks for EAC or ESCC were combined and analyzed for multiplicative effects. RESULTS: Our analyses includes 327 patients with EAC and 106 patients with ESCC. Low or intermediate activity enzyme genotypes for GSTM1, GSTA1, GSTP1 I105V and A114V as well as for GSTT1, did not significantly modify the risk for ESCC or EAC in our Dutch population. CONCLUSION: Functional genotypes in GST genes are not involved in EAC or ESCC susceptibility in Caucasians, in contrast to results on ESCC from Asia or Africa.

Contains fulltext : 111001.pdf (Publisher’s version ) (Closed access) Esophageal cancer (EC) has a globally increasing incidence with poor curative treatment options and survival rates. Crucial risk factors are exposure to toxins or carcinogens. Microsomal epoxide hydrolase (mEH) is a biotransformation enzyme essential for the detoxification of xenobiotics. Polymorphisms in exon 3 and exon 4 of the microsomal epoxide hydrolase gene (EPHX1) modify catalytic activity of this enzyme and subsequently may play a role in EC etiology. This case-control study investigated whether these polymorphisms in the EPHX1 gene influence esophageal cancer susceptibility in a Dutch Caucasian population. A case-control study including 349 Caucasian EC patients and 581 Caucasian healthy controls was conducted and the polymorphisms Tyr113His (exon 3) and His139Arg (exon 4) in the EPHX1 gene were determined, using polymerase chain reaction. The distribution of exon 3 and exon 4 genotypes were compared between cases and controls. Analyses included a stratification according to tumor histology; esophageal adenocarcinoma (EAC) or squamous cell carcinoma (ESCC). Furthermore, on the basis of allelic in vitro enzyme activity assays, exon 3 and 4 genotypes were combined and categorized according to their predicted high, medium or low enzyme activity. Homozygosity and heterozygosity for both exon 3 and 4 polymorphisms were correlated with a decreased esophageal squamous cell carcinoma risk. Heterozygosity and homozygosity for both polymorphisms correlated with an increased and a decreased esophageal adenocarcinoma risk, respectively. Predicted intermediate and high activity genotypes were risk and protective factors for esophageal squamous cell carcinoma and esophageal adenocarcinoma, respectively. However, none of these associations were statistically significant. In conclusion, the polymorphisms in exon 3 and exon 4 of the EPHX1 gene do not seem to be modifiers of esophageal squamous cell carcinoma or esophageal adenocarcinoma risk in Dutch Caucasians. 01 juni 2012

Postpyloric enteral feeding often requires endoscopic or fluoroscopic placement of a feeding tube. Self-propelled feeding tubes are designed to facilitate spontaneous migration into the jejunum. This study aimed to assess the rate of success and time to migrate a self-propelled feeding tube to jejunal position using erythromycin, a prokinetic agent.Non-critically ill patients with pancreatitis who required jejunal enteral feeding were included. A self-propelled nasoenteric feeding tube was placed into the stomach using either placebo or erythromycin. At 24 and 48 hours after initial placement, an abdominal x-ray was taken to determine the position of the tube.Forty subjects were included and randomized. After 48 hours, there was no difference in the rates of success between placebo 56% (9/16) and erythromycin 50% (10/20) (P = .71).Self-propelled feeding tubes migrated into the jejunum in 53% of the subjects within 48 hours. However, this study failed to determine any benefit of erythromycin in terms of success or time to migrate to jejunal position using a self-propelled feeding tube. Selection of subjects without impaired motility and tachyphylaxis may have contributed to clinical failure of erythromycin as a prokinetic agent in this study.

Item does not contain fulltext A patient who presented with upper abdominal pain, nausea and ascites together with peripheral eosinophilia is described. Based on a surgical full-thickness biopsy of the antrum, the diagnosis of eosinophilic gastroenteritis was made. Treatment with prednisone resulted in a clinical response, but the prednisone dose could not be lowered below 5 mg. We preferred to treat the patient with corticosteroids with minimal systemic side effects. As there was gastric involvement, we could not give enteric-coated budesonide capsules. Therefore, we treated the patient with budesonide tablets, which were designed originally for use as a clysma but now are given orally. With this treatment regimen, the patient has been in remission for more than 2 years.

METHODS: Two study groups were recruited, 252 patients with esophageal carcinoma and 240 healthy controls, matched for race, age, gender and recruiting area. DNA was isolated from whole blood and used for genotyping. PCR products were digested with restriction enzymes and products were analyzed by agarose gel electrophoresis. Odds ratios (OR) and 95% confidence intervals (CI) were estimated. RESULTS: The distribution of the -1195 A-->G polymorphism was significantly different in esophageal cancer patients compared to controls. The -1195 GG genotype resulted in a higher risk of developing esophageal adenocarcinoma (OR = 3.85, 95% CI: 1.45-10.3) compared with the -1195 AA genotype as a reference. The -765 G-->C genotype distribution was not different between the two groups. The GG/GG haplotype was present more often in esophageal adenocarcinoma patients than in controls (OR = 3.45, 95% CI: 1.24-9.58; with AG/AG as a reference). The same trends were observed in patients with squamous cell carcinomas, however, the results did not reach statistical significance. CONCLUSION: Presence of the COX-2 -1195 GG genotype and of the GG/GG haplotype may result in a higher risk of developing esophageal carcinoma.

Contains fulltext : 50575.pdf (Publisher’s version ) (Closed access) BACKGROUND: Alexithymia, where a person has difficulty in distinguishing between emotions and bodily sensations, is considered to be a character trait and a vulnerability factor for various psychosomatic disorders. Assessing alexithymia in patients with gastrointestinal (GI) symptoms before endoscopy might therefore be useful in selecting patients who are more prone to functional GI disorders. GOAL: To determine whether alexithymia might be a useful factor in predicting GI endoscopy outcomes. STUDY: Patients referred for endoscopy between February 2002 and February 2004 were enrolled. They were asked to report alexithymia on the Toronto Alexithymia Scale-20 2 weeks before endoscopy. Information about endoscopic diagnoses was obtained from medical files. RESULTS: A total of 1141 subjects was included (49% male), of whom 245 (21%) reported alexithymia. There was no difference in mean+/-SD alexithymia scores between patients with (51+/-12) and without (50+/-12) an endoscopic organic abnormality at GI endoscopy. When divided into subgroups, according to the most prominent finding at either upper or lower GI endoscopy, there was no association with alexithymia. Patients with alexithymia reported a worse sensation of GI symptoms during the last weeks before enrollment in the study (mean+/-SD symptom severity score: 42+/-34 vs. 34+/-30, respectively; P

Contains fulltext : 50425.pdf (Publisher’s version ) (Closed access) BACKGROUND AND STUDY AIMS: Upper gastrointestinal endoscopy in patients with functional dyspepsia is often carried out merely to reassure patients that symptoms are not due to serious pathology. The aim of this study was to compare anxiety, depression, and health-related quality of life as proxy values for reassurance in patients with functional dyspepsia before and after upper gastrointestinal endoscopy. PATIENTS AND METHODS: Consecutive patients referred for endoscopy between February 2002 and February 2004 were included in the study. They were asked to score anxiety and depression using the Hospital Anxiety and Depression Scale, health-related quality of life using the EuroQol-5D questionnaire, and their impression of their own general health using a visual analogue scale, 2 weeks before endoscopy and again 1 month afterwards. RESULTS: A total of 420 patients were included, 42 % of whom were found to have an organic abnormality of some sort during upper gastrointestinal endoscopy. Neither the anxiety nor the depression frequencies differed significantly before and after endoscopy, either in patients with organic abnormalities at endoscopy or in those without. The general impression of health did not change after endoscopy either: organic abnormalities 62.7 +/- 27.4 vs. 64.9 +/- 24.2, P = 0.28; functional dyspepsia 61.0 +/- 27.9 vs. 62.8 +/- 27.2, P = 0.39. Only patients who had organic abnormalities reported a slightly improved quality of life 1 month after endoscopy: 0.74 +/- 0.15 vs. 0.78 +/- 0.12, P < 0.01. CONCLUSION: In patients with functional dyspepsia, upper gastrointestinal endoscopy does not improve psychological well-being or health-related quality of life. In view of the invasiveness, cost, and potential harm associated with endoscopy, careful consideration should be given to whether this procedure should be carried out merely for the sake of the patient's "peace of mind".

Contains fulltext : 48011.pdf (Publisher’s version ) (Closed access) BACKGROUND: Limited information is available about anxiety, depression and psychotropic medication use in patients referred for gastrointestinal endoscopy. AIM: To determine anxiety and depression and its association with endoscopic findings in a representative sample of patients with persistent gastrointestinal symptoms prior to endoscopy. METHODS: Patients referred to the hospital for endoscopy between February 2002 and February 2004 were asked to score anxiety and depression on the Hospital Anxiety and Depression Scale 2 weeks prior to endoscopy. Information about endoscopic diagnoses was obtained from medical files. RESULTS: A total of 1298 subjects was studied (600 upper gastrointestinal endoscopies and 698 lower gastrointestinal endoscopies). Patients referred for upper gastrointestinal endoscopy used most psychotropic agents (24%; odds ratio = 3.1; 95% confidence interval = 2.3-4.2), especially patients with an organic abnormality when compared with patients without an organic abnormality (42% versus 8%; odds ratio = 8.6; 95% confidence interval = 5.4-14.0). Patients with colonic polyps were more anxious (odds ratio = 1.7; 95% confidence interval = 1.0-2.9) and depressed (odds ratio = 1.8; 95% confidence interval = 1.1-3.1) than other patients referred for lower gastrointestinal endoscopy. CONCLUSIONS: There is no difference in anxiety nor depression between patients with and without organic abnormalities at endoscopy. Patients with colonic polyps are more anxious and depressed than other patients referred for lower gastrointestinal endoscopy. Psychotropic medication use is highest among patients with an organic abnormality in the proximal gastrointestinal tract.

Analysis of nuclear DNA extracted from stool specimens (1) is a recent addition to cancer diagnostics (2)(3)(4). Most studies have focused on the detection of sequence variations in tumor suppressor genes and oncogenes and on their correlation with clinical stage. In addition, however, the amount of human DNA in feces may be increased in individuals with colorectal cancer. Villa et al. (5) found that β-globin sequences were amplified by PCR more frequently in patients with either colorectal carcinoma or adenomas than in healthy individuals. Ahlquist et al. (6) demonstrated that large DNA fragments were amplified from DNA in stool samples from colorectal cancer patients more frequently than from healthy volunteers. In view of these results, we developed a real-time PCR assay for quantification of human DNA in stool samples. Human stool samples were collected from 15 healthy adult volunteers (mean age, 46 years; range, 21–78 years) not on any dietary restrictions or antibiotic treatment and from 13 patients (mean age, 71 years; range, 49–81 years) who were diagnosed with colorectal cancer. All volunteers and patients gave informed oral consent. Stools were collected before any preparation for colonoscopy. Absolute care was taken to avoid hydration of the samples until further processing (1). Under these circumstances, solid stool samples can be stored at 4 °C for several days without significant degradation of the DNA. All stool samples from both groups were processed within 48 h after collection. DNA was isolated from 200-mg fresh solid human stool samples with use of the QIAamp …
