- OBJECTIVES: To identify risk factors of carcinoma of the extrahepatic biliary tract in men. METHODS: Newly diagnosed and histologically confirmed patients, 35-70 years old, were interviewed between 1995 and 1997 in Denmark, Sweden, France, Germany and Italy. Population controls were frequency-matched by age and region. Adjusted odds ratios and 95%-confidence intervals were estimated by logistic regression. RESULTS: The analysis included 153 patients and 1421 controls. The participation proportion was 71% for patients and 61% for controls. Gallstone disease was corroborated as a risk factor for extrahepatic biliary tract carcinoma in men (odds ratio 2.49; 95% confidence interval 1.32-4.70), particularly for gall bladder tumors (odds ratio 4.68; 95% confidence interval 1.85-11.84). For a body mass index [height (m) divided by squared weight (kg2)] >30 at age 35 years, an excess risk was observed (odds ratio 2.58; 95% confidence interval 1.07-6.23, reference: body mass index 18.5-25) that was even stronger if the body mass index was >30 for the lowest weight in adulthood (odds ratio 4.68; 95% confidence interval 1.13-19.40). Infection of the gall bladder, chronic inflammatory bowel disease, hepatitis or smoking showed no clear association, whereas some increase in risk was suggested for consumption of 40-80 g alcohol per day and more. CONCLUSIONS: Our study corroborates gallstones as a risk indicator in extrahepatic biliary tract carcinoma. Permanent overweight and obesity in adult life was identified as a strong risk factor for extrahepatic biliary tract carcinoma, whereas we did not find any strong lifestyle-associated risk factors. Inconsistent results across studies concerning the association of extrahepatic biliary tract carcinoma with overweight and obesity may be explained by the different approaches to assess this variable.

- BACKGROUND: Gastrointestinal (GI) symptoms are common in myotonic dystrophy (MD). Diarrhoea is one of the more disabling of these GI complaints. The mechanisms behind diarrhoea in MD have not previously been investigated systematically. OBJECTIVE: To elucidate the mechanisms behind diarrhoea in MD. METHODS: Twenty patients with MD and suffering from diarrhoea were investigated in order to detect malabsorption (blood tests and faecal fat excretion) and bile acid malabsorption ([75Se]selenahomocholic acid-taurine (SeHCAT) retention) and to study intestinal morphology (duodenal and rectal biopsies). RESULTS: Two patients had deficiency of folic acid and four showed reduced levels of pancreatic isoamylase, but none of them had steatorrhoea. Two out of eight patients had abnormal bile acid breath tests with normal SeHCAT, indicating small bowel bacterial overgrowth and 12 displayed reduced SeHCAT retention. Duodenal biopsies were normal in eight patients and five out of nine rectal biopsies displayed slight inflammation. CONCLUSIONS: A possible mechanism of diarrhoea in MD could be identified in most of the patients. Bile acid malabsorption seems to be a frequent cause and can be treated successfully

- OBJECTIVE: Autoantibodies against goblet cells in the gastrointestinal mucosa have been described in patients with inflammatory bowel disease (IBD) but a corresponding autoantigen has not yet been identified. The aim of this study was to identify such an antigen. METHODS: First, 10 candidate autoantigens were discarded based on double stainings of appendiceal sections and a mucin-producing cell line (HT29-mtx). Second, an appendiceal cDNA library was immunoscreened with IBD sera. RESULTS: Three out of 48 positive clones were identified as complement C3. Using immunoprecipitation of in vitro transcribed and translated C3, seven of 17 primary sclerosing cholangitis patient sera, 15 of 65 IBD sera, and none out of 54 sera from healthy blood donors showed C3 immunoreactivity. The results were confirmed using western blot and an enzyme-linked immunosorbent assay with alternative sources of C3 protein. CONCLUSION: In conclusion, we have identified complement C3 as a potential autoantigen in IBD and primary sclerosing cholangitis.

- OBJECTIVE: To analyze the subgingival microflora composition of inflammatory bowel disease (IBD) patients with untreated chronic periodontitis and compare them with systemically healthy controls also having untreated chronic periodontitis.METHOD: Thirty IBD patients [15 with Crohn's disease (CD) and 15 with ulcerative colitis (UC)] and 15 control individuals participated in the study. All patients had been diagnosed with untreated chronic periodontitis. From every patient, subgingival plaque was collected from four gingivitis and four periodontitis sites with paper points. Samples from the same category (gingivitis or periodontitis) in each patient were pooled together and stored at -70 °C until analysis using a checkerboard DNA-DNA hybridization technique for 74 bacterial species.RESULTS: Multiple-comparison analysis showed that the groups differed in bacterial counts for Bacteroides ureolyticus, Campylobacter gracilis, Parvimonas micra, Prevotella melaninogenica, Peptostreptococcus anaerobius, Staphylococcus aureus, Streptococcus anginosus, Streptococcus intermedius, Streptococcus mitis, Streptococcus mutans, and Treponema denticola (P<0.001). CD patients had significantly higher levels of these bacteria than UC patients either in gingivitis or in periodontitis sites (P<0.05). CD patients harbored higher levels of P. melaninogenica, S. aureus, S. anginosus, and S. mutans compared with controls both at gingivitis and at periodontitis sites (P<0.05). UC patients harbored higher levels of S. aureus (P=0.01) and P. anaerobius (P=0.05) than controls only in gingivitis sites.CONCLUSION: Our study showed that even with similar clinical periodontal parameters, IBD patients harbor higher levels of bacteria that are related to opportunistic infections in inflamed subgingival sites that might be harmful for the crucial microbe-host interaction.

- AIM: To compare 14 and 24 weeks treatment to patients with HCV genotype 2 or 3 infection and rapid virological response (RVR). MATERIALS AND METHODS: Patients included in two Scandinavian trials, one nonrandomized pilot trial (n=122) and one randomized controlled trial (RCT) (n=428) were entered into a pooled database. In both trials treatment naïve patients with genotype 2 or 3 were treated with pegylated interferon alpha 2b (1.5 mug/kg, subcutaneous) weekly and ribavirin (800-1400 mg, orally) daily. Primary endpoint was sustained virological response (SVR). RVR was defined as HCV RNA less than 50 IU/ml after 4 weeks of treatment. In the pilot trial all patients with RVR were treated for 14 weeks and in the RCT patients with RVR were randomised to either 14 or 24 weeks treatment. Patients treated per protocol were included in the primary analysis. The noninferiority margin was set to be 10% between the two groups with a one-sided 5% significance level. RESULTS: In patients with RVR and genotype 2 or 3 SVR was obtained in 181 of 199 (91.0%) and 93 of 98 (94.9%) after 14 and 24 weeks treatment, respectively. The observed difference in SVR rates was 3.9% (90% confidence interval: +1 to -8.8). The relapse rate was highest among those older than 40 years and those with genotype 3 and high viral load, but prolongation of treatment from 14 to 24 weeks did not reduce the relapse rate substantially in any of these groups. CONCLUSION: In patients with HCV genotype 2 or 3 infection and RVR 14 weeks treatment is noninferior to 24 weeks.

- When investigating a patient with suspected celiac disease (CD), several other conditions must be considered, including potential infection with Giardia lamblia. Although giardiasis is rare, its histopathological and serological picture may resemble that of CD. We report the case of a young man with diabetes mellitus and a family history of CD referred to our hospital because of diarrhoea and weight loss. Investigation showed, among other factors, partial villous atrophy in duodenal biopsies and elevated immunoglobulin A antitissue transglutaminase antibodies. The patient was diagnosed with CD and recommended a gluten-free diet. At the same time, faecal tests were conducted, indicating the presence of G. lamblia. The patient was treated and improved, even after discontinuing the gluten-free diet. Subsequent follow-up after 6 months showed total regression of mucosal histopathology and a normal antitissue transglutaminase antibodies level.

- Background. Many individuals are infected with the bacterium Helicobacter pylori. Some develop ulcers or mucosal atrophy. Aims. To correlate the histological characteristics of the H. pylori-induced gastritis to the immunoblot pattern of the H. pylori infection and to compare the presence of H. pylori bacteria in tissue specimens with ELISA serology and immunoblot analysis. Methods. One hundred and sixty-six consecutive patients were referred to gastroscopy. Forty patients were excluded for various reasons and 126 were included in the study. Results. Twenty-three patients had ulcerations and 25 erosions. Ninety-two (73%) had a chronic gastritis and in 90 (71%) it involved both the antrum and corpus. Ninety-one (72%), of whom 96% had a chronic gastritis, had visible bacteria in the tissue specimens, used as the 'gold standard' for the detection of infection. In patients with chronic gastritis 65 (70%) had positive H. pylori ELISA serology, 27 (30%) had negative H. pylori ELISA, while 76 (83%) had a positive immunoblot pattern. The ELISA positive patients had more advanced chronic gastritis but a lower frequency of metaplasia and atrophy. Acute inflammatory activity in the chronic gastritis had a high immunoreactivity to 120 kDa (CagA) protein and was significantly correlated to antibody reactivity to proteins in the 53-65 kDa range (heat shock proteins) and to a 43 kDa subunit. Metaplasia and atrophy in antrum was associated with a 62 kDa protein band. Conclusion. Almost all H. pylori-infected patients had a pangastritis, visible in both antrum and corpus. Acute inflammatory activity in the chronic gastritis and the presence of metaplasia and atrophy in antrum were associated with a specific immunoblot pattern, indicating infection with more virulent strains. Immunoblot analysis had a better sensitivity than ELISA H. pylori serology.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: Two functional genetic variants in the inosine triphosphatase (ITPA) gene have been shown to be strongly associated with protection from ribavirin (RBV)-induced hemolysis. We aimed at evaluating this finding in a chronic hepatitis C genotype 2/3 cohort with a predominance of genotype 3 patients where available data are scarce. A second objective was to determine whether a protective association translated into the need for RBV reduction and hence a possible impact on treatment response. METHODS: Overall, 457 patients were recruited from two trials of genotype 2/3 patients treated with pegylated interferon α-2b and weight-based RBV. rs1127354 and rs7270101 were genotyped and a composite ITPAase deficiency variable was graded according to the two single nucleotide polymorphisms. The primary endpoints were hemoglobin (Hb) decline from baseline and Hb decline of more than 3 g/dl at week 4. RESULTS: Both single nucleotide polymorphisms and the composite ITPAase deficiency variable were strongly and independently associated with protection from a decline in Hb at week 4 in multivariate linear regression models (Prs1127354=7.0×10, Prs7270101=0.0036, PITPase deficiency variable =6.3×10). Patients with any degree of reduced ITPAase activity were less likely to have their RBV dose reduced (odds ratio 0.39, 95% confidence interval 0.16-0.96, P=0.040), although this did not translate into increased rapid viral response or sustained viral response (Prvr=0.93, Psvr=0.22). CONCLUSION: We have confirmed a strong association between functional ITPA variants and RBV-induced hemolysis and showed protection from RBV dose reduction, although this did not translate into increased rapid viral response or sustained viral response.

- OBJECTIVE: To investigate the frequency and nature of bowel symptoms in a population-based cohort of patients with systemic sclerosis (SSc), compared with healthy controls, and to relate these symptoms to health-related quality of life (HR-QOL). METHOD: Seventy-nine SSc patients and 158 matched controls answered a validated questionnaire on gastrointestinal (GI) symptoms and Medical Outcomes Study Short Form Health Survey (SF-36). Modified Miller Score, a composite score measuring faecal incontinence, was computed. RESULTS: Abnormal stool consistency, bloating, a feeling of incomplete evacuation, faecal incontinence and rectal bleeding were more frequently reported by SSc patients than controls. The ability for anorectal discrimination, and deferring defecation was diminished in SSc patients. Bowel function affected general well being in 30% of patients and social life in 20%. Patients had lower SF-36 scores, that is, worse HR-QOL than controls. Modified Miller Score did not correlate to the SF-36 scores in patients, but other lower GI symptoms, especially abdominal pain and bloating, were associated with diminished HR-QOL. CONCLUSION: Lower GI symptoms, including faecal incontinence, are more common in patients with SSc than in healthy controls and are of consequence to the individual patient's life. The lower prevalence of anorectal discrimination in the SSc patients suggests a neuronal defect in these patients. Increased awareness of these symptoms might stimulate a search for new diagnostic and therapeutic strategies.

- OBJECTIVE: Patients with extensive and long-standing ulcerative colitis have an increased risk of developing colorectal cancer and sub-epithelial fibrosis. The polypeptide transforming growth factor alpha (TGF-alpha) has mitogenic effects and it is believed that local overproduction may result in tumour formation and fibrosis. DESIGN: In the present study, we correlated the presence of TGF-alpha in ulcerative colitis with the degree of inflammation and with dysplasia. METHODS: Sixty two patients were investigated, 46 with ulcerative colitis (16 with active inflammation and 20 in remission, 10 with dysplasia of the colon), and 16 controls with normal colonoscopy and without a history of colitis. There were no overlaps between the subgroups. Tissue sections from colonic biopsies were examined and TGF-alpha was detected by immunohistochemistry. TGF-alpha-containing cells were characterized by double-staining with antibodies to eosinophil cationic protein (ECP). An antibody (EG2) recognizing eosinophils with an activated phenotype was also used. RESULTS: The median number of TGF-alpha-containing cells in the mucosa was 24 per mm2 (inter-quartile range 10-51) in controls, 186 per mm2 (73-245) in ulcerative colitis with active inflammation, 76 per mm2 (52-198) in remission, and 130 per mm2 (66-203) in areas of dysplasia. Double-staining for TGF-alpha and ECP revealed that most of the TGF-alpha-containing cells were eosinophils, and most had an activated phenotype as judged by staining with EG2. CONCLUSIONS: The presence of TGF-alpha-containing cells in colonic mucosa is increased both in active inflammation and during remission in ulcerative colitis. Dysplasia is not associated with any significant increase in TGF-alpha-containing cells. The majority of TGF-alpha-containing cells are eosinophils with an activated phenotype. TGF-alpha released from these cells could be important for the development of complications seen in ulcerative colitis, such as cancer and fibrosis.

- Introduction The colonic mucus layer plays an important role in the protection of the intestinal epithelium and mainly consists of mucin glycoproteins (primarily MUC2 in the colon) trefoil factor 3 (TFF3) and secretory IgA. Butyrate is a major end product of fermentation of dietary fibres and is associated with beneficial effects on colonic health. Earlier in-vitro and animal studies showed that butyrate modulates MUC2 and TFF3 expression and mucin secretion, although data from human studies are not yet available. Methods Sixteen healthy volunteers and 35 ulcerative colitis (UC) patients in clinical remission self-administered a 60 ml rectal enema containing 100 mmol/l butyrate or placebo once daily for 2 and 3 weeks, respectively. After each treatment, biopsies were taken from the distal sigmoid for quantitative RT-PCR and immunohistochemical analysis of MUC2 and TFF3. In addition, mucosal sections were stained with high iron diamine-alcian blue to distinguish between sialomucins and sulphomucins. To analyse total mucin secretion and secretory IgA concentrations, 24 h faeces were collected during the day before the endoscopic examination. Results The butyrate intervention did not significantly modulate the expression of MUC2 ( fold change: 1.04 and 1.05 in healthy volunteers and ulcerative colitis patients, respectively) or TFF3 (fold change: 0.91 and 0.94 in healthy volunteers and UC patients, respectively). Furthermore, the percentage of sialomucins, mucus secretion and secretory IgA concentrations were not affected by the butyrate intervention in both the groups. Conclusion Butyrate exposure in healthy volunteers and UC patients in remission did not affect the measured parameters of the colonic mucus layer.

- OBJECTIVE: The prevalence of Helicobacter pylori in chronic peptic ulcer is well known. In this study the frequency of H. pylori infection was investigated in patients with acute bleeding peptic ulcer.DESIGN AND SETTING: Prospective study in a district hospital.PATIENTS: Seventy consecutive patients with acute bleeding peptic ulcer.INTERVENTIONS: Diagnosis was verified on admission by endoscopy, and healing was examined at follow-up. Previous history of ulcer disease, presence of dyspeptic symptoms and consumption of non-steroidal anti-inflammatory drugs were recorded.MAIN OUTCOME MEASURES: H. pylori infection was detected by two serological tests in samples obtained on admission for the acute bleeding episode, and at follow-up 1-3 months later.RESULTS: With a commercial latex immunoassay, 53% of the patients with gastric ulcer and 62% with duodenal ulcer were shown to possess H. pylori antibodies. In the other test, a standard enzyme-linked immunosorbent assay based on cell surface protein antigens of H. pylori with high sensitivity and specificity, 81% of gastric ulcer patients and 85% of duodenal ulcer patients were shown to have H. pylori antibodies.CONCLUSION: The results indicate that H. pylori infection plays a major aetiological role in patients with acute bleeding peptic ulcer.

- Introduction: Infliximab was launched for the treatment of Crohn's disease (CD) in 1999. We set up a follow-up protocol to meticulously study disease development with repeated infusions of infliximab. Aim: To follow the effects of infliximab treatment on disease activity, blood chemistry, quality of life, plasma nitrite, and titers of Saccharomyces cerevisiae antibodies (ASCA). Methods: During 1999–2008, CD patients were monitored for disease activity by Harvey–Bradshaw index, blood chemistry with hemoglobin, albumin, C-reactive protein, platelet count, leukocyte count and creatinine, quality of life by the Short Health Scale, and plasma nitrite. During the first year of treatment, follow-up was done repeatedly before and 1 week after each infusion and thereafter every year before the last infusion for 5 years. ASCA was analyzed by flow cytometry with fluorescein isothiocyanate-labelled antibodies. Results: A total of 1061 infusions were given to 103 patients; 92 responders and 11 nonresponders. Responders were further monitored and Harvey–Bradshaw index decreased with infusions during the first year of treatment (P<0.0001), whereas hemoglobin (P<0.01) and albumin (P<0.001) increased, C-reactive protein (P<0.01) decreased, platelets (P<0.001) increased, and leukocytes (P<0.01) decreased. Creatinine was not affected. Short Health Scale (questions analyzed separately) decreased (P<0.0001), and nitrite (P<0.001) increased. During the next 4 years the improved values remained stable. Adverse effects were noted among 32% of the patients; local circulatory reactions being most common. No correlation between ASCA titers and inflammatory activity or infliximab treatment was found. Conclusion: Infliximab treatment is highly effective in responders and maintains symptomatic improvement and low inflammatory activity over years in CD patients.

- Objective: The aims of this study were to analyse the health-related quality of life of patients with ulcerative colitis and to assess in what way demographic and disease-related factors influence patients' experiences of this, in order to interpret the results of health-related quality of life assessment more correctly.Patients and methods: We carried out a cross-sectional evaluation of 300 consecutive patients with ulcerative colitis from the catchment areas of Linköping University Hospital and Örebro University Hospital in Sweden. Health-related quality of life was measured using four questionnaires: the IBDQ, the RFIPC, the SF-36 and the PGWB. Disease activity was evaluated using a one-week symptom diary, blood tests and rigid sigmoidoscopy. Demographic factors (gender, age, civil status, educational level), disease-related factors (disease duration, disease extent, disease activity) and presence of co-morbidity were obtained.Results: Health-related quality of life was mainly impaired in the psychological and social areas and to a much lesser degree in physical areas. Patients with relapse had significantly more disease-related worries and concerns (the RFIPC), more impaired social functioning (the IBDQ and SF-36), and a lower feeling of well being (the IBDQ, the SF-36 and the PGWB). However, their physical function (SF-36) was no worse than patients in remission. Besides the symptom burden of the current disease, co-morbidity and female gender were associated with a lower health-related quality of life.Conclusion: To correctly interpret health-related quality of life assessments, it is necessary to consider co-morbidity and gender distribution in addition to the symptom burden of the disease studied.

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

METHODS: The study was prospective and population based. The cohort included all patients who underwent colonoscopy during the year 2010 at the National University Hospital of Iceland. Indications for endoscopies and drug history were recorded in a systematic manner. The inclusion criteria were overt bleeding leading to hospitalization or occurring in hospitalized patients. The use of NSAIDs, low-dose aspirin, warfarin, selective serotonin receptor inhibitors, and bisphosphonates before GIB was also checked in a Pharmaceutical Database covering all drug prescriptions in the country. A control group included patients who underwent colonoscopy during the study period and did not have GIB. RESULTS: Altogether, 1134 patients underwent 1275 colonoscopies. Overall, 163 patients had ALGIB. The crude incidence for ALGIB was 87/100 000 inhabitants/year. The most common findings were diverticulosis (23%) and ischemic colitis (16%). A total of 7.4% of individuals had endoscopic therapy and none had undergone surgery. Two (1.2%) patients died because of ALGIB, both with severe comorbidities. Overall, 19% with ALGIB were on NSAIDs versus 9% in nonbleeders (P=0.0096); 37% with ALGIB were on low-dose aspirin versus 25% in nonbleeders (P=0.0222). CONCLUSION: The incidence for ALGIB is the highest reported to date. The most common reasons for ALGIB were diverticulosis and ischemic colitis. Mortality during hospitalization was very low. NSAIDs and low-dose aspirin seem to increase the risk for ALGIB.

- Irritable bowel syndrome (IBS) is a chronic, disabling and functional gastrointestinal disorder. Effective treatments are lacking. Self-care and coping with symptoms are considered important but little is known about what patients with IBS actually do to manage their illness. The aim of this study was to explore how patients with long-term experience of living with IBS perceive their situation and manage illness in daily life.

- OBJECTIVES: Alpha1-antitrypsin deficiency (AATD) is a common genetic cause of chronic liver disease. According to retrospective studies, up to 25% of those with homozygous ZZ (Glu 342 to Lys) AATD suffer from liver cirrhosis and/or liver cancer in late adulthood. We hypothesized that the plasma markers for liver fibrosis, necrosis, and apoptosis may identify AATD individuals at higher risk for liver diseases. METHODS: The study cohort included 52 clinically healthy ZZ AATD individuals of 34 years of age, identified in the Swedish neonatal screening of 1972-1974, and 81 age-matched controls with normal MM AAT variant. We analyzed plasma levels of the enhanced liver fibrosis (ELF) panel, including plasma tissue inhibitor of metalloprotease-1, amino-terminal propeptide of type III collagen and hyaluronic acid (HA), and the M30 and M65 antigens, markers for apoptosis/necrosis. RESULTS: Higher levels of tissue inhibitor of metalloprotease-1 (52%, P<0.001), amino-terminal propeptide of type III collagen (12%, P<0.05), HA (17% not significant), and M65 (13.4%, P=0.043) were found in ZZ than in MM patients. In the ZZ group, plasma levels of AAT correlated with M65 (P<0.01) and with HA (P<0.05). On the basis of the ELF panel, M30 and M65, a logistic regression model enabled us to correctly classify 81.2% of the originally grouped ZZ and MM cases with a sensitivity of 73.1% and a specificity of 86.4%. CONCLUSION: The ELF markers are associated with ZZ AATD at early adulthood, and can be considered as a useful tool to identify ZZ cases at an increased risk of developing liver diseases later in life.

- BACKGROUND AND STUDY AIM: Few previous studies have addressed the agreement between endoscopy and histology regarding Barrett's oesophagus in unselected endoscopy patients. Our aim was to quantify this agreement, and to study its relation to clinical and endoscopic characteristics in consecutive patients coming for first-time gastroscopy. METHODS: We invited consecutive patients aged 18-79 years and endoscoped for the first time at endoscopy units exclusively serving defined catchment areas in southeast Sweden. Endoscopic and clinical data were recorded according to a predetermined protocol, and biopsies were taken from the distal oesophagus in all patients. RESULTS: Among 705 patients included, 17% [95% confidence interval (CI): 14-20] had endoscopically visible columnar mucosa above the oesophagogastric junction and 38% (95% CI: 34-42) had columnar mucosa in at least one biopsy irrespective of the endoscopic finding. The overall concordance between endoscopy and histology regarding presence (or absence) of columnar mucosa above the oesophagogastric junction was 74% (95% CI: 71-77) and the agreement beyond chance, as measured by Kappa (?) statistics, was fair, ?=0.38 (95% CI: 0.32-0.45). The agreement between the endoscopic assessment and intestinal metaplasia at biopsy was 86% (95% CI: 83-88), but ? was only 0.31 (95% CI: 0.21-0.41). Our data were consistent with a lower threshold for macroscopic detection of columnar epithelium above the oesophagogastric junction, when risk factors for Barrett's oesophagus were present. CONCLUSION: The agreement between macroscopic and microscopic assessments of Barrett's oesophagus is no more than fair, and partly dependent on the presence of patient characteristics suggestive of pathology in this region. © 2007 Lippincott Williams & Wilkins, Inc.

- Background Functional gastrointestinal disorders (FGIDs) are diagnosed according to expert consensus criteria based on recall of symptoms over periods of 3 months or longer. Whether the expert opinion concords with underlying disease process and whether individual recall is accurate are both in doubt. This study aimed to identify naturally occurring clusters of individuals with respect to symptom pattern, evaluate their significance, compare cluster profiles with expert opinion and evaluate their temporal stability.Methods As part of a random population study of FGID-related symptoms, we first explored the use of prospective stool and symptom diaries combined with empirical grouping of individuals into clusters using nonhierarchical cluster analysis.Results The analysis identified two clusters of individuals, one of which was characterized by elevated scores on all domains of symptoms (26% of the sample) and one that was low to average on all domains (74% of the sample). Cluster membership was found to be stable over a long interval. Clusters were found to differ on most domains of quality-of-life (d = 0.46–0.74), self-rated health (d = −0.42) and depression (d = −0.42) but not anxiety. Prevalence of clinically diagnosed irritable bowel syndrome (IBS) was higher in the more impacted cluster (33%) compared with the healthy cluster (13%; P < 0.0001).Conclusion A naturalistic classification of individuals challenges consensus criteria in showing that some IBS individuals have a symptom experience not unlike health. The proposed approach has demonstrated temporal stability over time, unlike consensus criteria. A naturalistic disease classification system may have practical advantages over consensus criteria when supported by a decision-analytic system.

- Background: Clinical understanding of gastrointestinal symptoms is commonly based on patient reports of symptom experience. For diagnosis and treatment choices to be appropriate, symptom reports need to be accurate. We examined the agreement between questionnaire recall and prospective diary enumeration of symptoms relevant to the irritable bowel syndrome.Patients and methods: Data are reported from a randomly selected general population sample (n=238) and also a primary healthcare centre (PHC) sample (n=503, 10 PHCs). All the patients completed the questionnaires, which included Rome III-qualifying irritable bowel syndrome items and a stool and symptom diary over either 7 or 14 days. Agreement between retrospective questionnaire reports and prospective diaries was evaluated.Results: Concordance between questionnaires and diaries was highest for the simple construct of the occurrence of abdominal pain, although after adjusting for possible chance, agreement was only moderate in the general population sample. More complex constructs, such as pain relieved by defecation, yielded poorer concordance. In general, concordance was stronger among PHC respondents than in the general population sample.Conclusion: Concordance between questionnaires and diaries was generally poor and related to the complexity of the symptom construct and the type of respondent. The information used to classify individuals based on patient self-report may be unreliable, and therefore, more effort is needed to develop data collection instruments.

- Objective Cardiac dysfunction, in particular left ventricular diastolic dysfunction, is common in cirrhosis. We aimed to investigate the impact of cardiac dysfunction on health-related quality of life (QoL) in liver cirrhosis. Materials and methods A total of 88 cirrhotic liver transplant candidates with an available echocardiogram and ECG completed the Short form-36 (SF-36) and Fatigue Impact Scale. In a subgroup of 61 patients, levels of cardiac biomarkers, in particular serum N-terminal pro-brain natriuretic peptide, adiponectin, and high-sensitive troponin T, were also measured. Results Although left ventricular systolic diameter was related to a lower SF-36 physical component summary, neither left ventricular diastolic dysfunction nor any other echocardiographic feature was found to be associated with any other SF-36 or Fatigue Impact Scale domain (P>0.05 for all). On linear regression analysis after adjustment for confounders, a prolonged QTc interval was found to be related to a lower SF-36 mental component summary score (beta = -9.7, P = 0.009) and increased physical fatigue (beta = 10.5, P= 0.004). Neither serum N-terminal pro-brain natriuretic peptide, high-sensitivity troponin T, nor adiponectin levels were found to be related to QoL (P> 0.05 for all). Serum adiponectin levels did not differ among patients with versus those without echocardiographic cardiac alterations (P> 0.05 for all). Conclusion A prolonged QTc interval, but not any echocardiographic abnormalities or cardiac biomarkers, seems to be predictive of QoL in cirrhosis. Copyright (C) 2015 Wolters Kluwer Health, Inc.

- BACKGROUND: End-stage liver disease is a medical problem with high morbidity and mortality. We have investigated the feasibility, safety, and efficacy of using autologous mesenchymal stem cells (MSCs) as a treatment. METHODS: Eight patients (four hepatitis B, one hepatitis C, one alcoholic, and two cryptogenic) with end-stage liver disease having Model for End-Stage Liver Disease score > or =10 were included. Autologous MSCs were taken from iliac crest. Approximately, 30-50 million MSCs were proliferated and injected into peripheral or the portal vein. Liver function and clinical features were evaluated at baseline and 1, 2, 4, 8, and 24 weeks after injection. RESULTS: Treatment was well tolerated by all patients. Liver function improved as verified by the Model for End-Stage Liver Disease score, which decreased from 17.9±5.6 to 10.7±6.3 (P<0.05) and prothrombin complex from international normalized ratio 1.9±0.4 to 1.4±0.5 (P<0.05). Serum creatinine decreased from 114±35 to 80±18 µmol/l (P<0.05). Serum albumin changed from 30±5 to 33±5 g/l and bilirubin from 46±29 to 41±31 µmol/l. No adverse effects were noted. CONCLUSION: Our data show that MSCs injection can be used for the treatment of end-stage liver disease with satisfactory tolerability. Furthermore, this treatment may improve clinical indices of liver function in end-stage liver disease.

- ObjectiveTo analyse the epidemiology of irritable bowel syndrome (IBS) symptoms in a random sample of the general population and in a subsample consenting to a colonoscopy, and to what extent this introduces symptom selection bias.Materials and methodsOverall, 3347 randomly selected Swedish adults aged 18-70 years were mailed the validated Abdominal Symptom Questionnaire (ASQ). Responders (n=2293; 68.5%) were contacted by phone, and 745 consented to a colonoscopy. All nonresponders were contacted by phone; 265 were reached and asked seven key ASQ questions. Colonoscopy participants also completed the Rome II Modular Questionnaire.ResultsThe prevalence of IBS on the basis of the mailed ASQ (troublesome abdominal pain and bowel disturbance in the past 3 months) was 26.2% [95% confidence interval (CI): 24.4-28.0] among the ASQ responders and 36.6% (95% CI: 33.2-40.1) among the colonoscopy participants (P<0.001). Nonresponders had a lower prevalence of IBS (15.8%; 95% CI: 11.4-20.3, P<0.001) than ASQ responders. Colonoscopy participants were slightly older than noncolonoscoped participants completing the ASQ (P<0.001), but men and women were equally represented and no significant socioeconomic differences were identified. The prevalence of IBS was 14.8% (95% CI: 12.2-17.5) on the basis of the Rome II Modular Questionnaire in colonoscopy participants and 14.5% (95% CI: 11.9-17.2) when visible inflammatory disease was excluded. Of the colonoscopy participants, 31.9% (95% CI: 28.5-35.3) were symptom free.ConclusionIBS symptoms are common and rarely explained by visible inflammatory disease or cancer. There was a modest selection bias by IBS in participants accepting a screening colonoscopy, but still, one-third were symptom free. Thus, conclusions for the general population can be made from findings in the study cohort.

Tidskriftsartikel (refereegranskat)abstract
- Intraductal papillary mucinous neoplasms (IPMNs), characterized by intraductal papillary growth and thick mucin secretion, have increasingly been recognized. Despite modern preoperative evaluation, major difficulties still remain in distinguishing malignant invasive types from benign IPMNs. Following a PubMed database search, all relevant abstracts and articles on IPMN published in English and Chinese were reviewed. Main-duct and the mixed type IPMNs carry a higher risk of malignancy as compared with branch-duct type IPMNs. Treatment of branch-duct type IPMNs remains controversial. Once operation is indicated, intraoperative frozen section of margins plays an important role in the decision concerning the extent and type of surgery. Pancreatectomy, partly preserving both endocrine and exocrine pancreatic function, is advocated for most patients with IPMN, though total pancreatectomy may be necessary in some. Both for patients subjected to surgery and those only observed, IPMN patients need regular close follow-up to identify recurrence or progressive disease.

- Objective: To study the effects of different doses of platelet activating factor receptor antagonist WEB 2170 on animal survival, haemodynamics, reperfusion and ultrastructural changes in the ischaemic liver in rats undergoing 90-min total hepatic inflow interruption (THII). Design: Sixty-five rats were divided into five groups. All animals underwent 90-min THII. Group 1 served as controls. Group 2 underwent THII alone. Group 3 received an intravenous injection of 1 mg/kg WEB 2170 prior to THII. Group 4 received a bolus injection of 3 mg/kg WEB 2170 before THII. Group 4 received a bolus injection of 3 mg/kg WEB 2170 before THII. Group 5 received 3 mg/kg WEB 2170 before, during and after THII. The liver reperfusion index using laser Doppler flowmetry, the time of ischaemic liver initiative reperfusion, and scanning electron microscopy were performed to evaluate the results of different dose schedules. Setting: Lund University Hospital, Lund, Sweden. Results: Animal survival rate, liver reperfusion index, the time of ischaemic liver initiative reperfusion and ultrastructural damage of the ischaemic liver were markedly improved in the groups treated with WEB 2170 compared with the non-treated 90-min THII group. The best result was obtained in the group receiving the three separate doses. Conclusion: In the 90-min THII model, WEB 2170 protects the liver from ischaemia-reperfusion injury and the spread of damage to the post-stasis splanchnic organs. These beneficial effects may be extended to hepatic transplantation or major resections of the liver.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To examine the effect of photodynamic therapy (PDT) on experimental liver tumours in rats. Design: An experimental liver tumour model was used. Each of a group of Fats had two tumours simultaneously inoculated into its liver. The tumour located in the left hepatic robe was used for PDT, and the other one, in the median lobe, as a control. The haem precursor delta-amino laevulinic acid (ALA), at a dose of 30 mg/kg body weight, was injected 60 min before laser irradiation. Rats in group I received ALA through a femoral vein. Those in group II received ALA through the portal vein. Group III had an injection of ALA solution through the portal vein plus hepatic inflow occlusion. Three and 6 days after the treatment, the rats were killed, and the tumours were measured, and ultrastructural changes were examined using scanning electron microscopy. Setting: Lund University Medical Laser Centre, Lund, Sweden. Results: The mean tumour volume of the treated tumours increased by factors of 1.9, 1.5 and 1.7 in groups I, II and III, respectively, compared with the pretreatment baseline value. However, the mean tumour volume in the control tumours increased by factors of 9.5, 4.3 and 4.8 in the respective groups. Under the light microscope, marked necrosis of the treated tumour and the surrounding liver tissue was observed. Scanning electron microscopy revealed heavy damage to the cells and vessels in the treated tumour. Conclusion: PDT with ALA is an effective treatment modality for rat liver tumours.
