    High burden of iron deficiency and different types of anemia in inflammatory bowel disease outpatients in Scandinavia: A longitudinal 2-year follow-up study2013In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 48, no 11, p. 1286-1293Article in journal (Refereed)
    Abstract [en]

    Objective. The prevalence of anemia in inflammatory bowel disease (IBD) has been broadly described. The recurrence, type and burden of anemia remain unenlightened. The primary objective was to describe this. The secondary objective was to evaluate the implementation of European guidelines. Materials and methods. This longitudinal follow-up study included 300 IBD outpatients from six centers in Scandinavia. Patients were enrolled in a research cohort, in which each center included 5% of their IBD cohort. The study was prospectively planned, while data were retrospectively collected. The burden of anemia was calculated as number of months with anemia. A Markov model was used to calculate the probabilities of transitioning between stages. The European guidelines were used as the standard for anemia management. Results. Anemia affected andgt; 50% of IBD outpatients during the 2-year observation period. Totally, 20% of the total observation time was spent in anemia. Over the 7200 months of observation, anemia was found in 1410 months. The most frequent type was combined anemia (63%). Combined anemia covers both anemia of chronic disease (ACD) and iron-deficiency anemia (IDA). Pure ACD was present in 21% of burden time, while pure IDA was present in 16% of burden time. The European guidelines have mainly been implemented. Conclusion. Anemia affected a majority of the IBD outpatients. One in five months, the patients were anemic. Anemia related to inflammation dominated the different types of anemia. Pure IDA was found in for 16%. These findings, despite a fair implementation of guidelines.

    Intraepithelial lymphocyte distribution differs between the bulb and the second part of duodenum2013In: BMC Gastroenterology, ISSN 1471-230X, E-ISSN 1471-230X, Vol. 13Article in journal (Refereed)
    Abstract [en]

    Background

    Evaluation of intraepithelial duodenal lymphocytosis (IDL) is important in celiac disease (CD). There is no established cut-off value for increased number of IELs in the bulb.

    We therefore investigated the relation between IEL counts in the bulb and duodenal specimens in non-celiac subjects.

    Methods

    The number of CD3+ IELs was determined in specimens from the second part of the duodenum and from the bulb in 34 non-celiac subjects. The numbers of IELs in the villus tip and sides were counted and the quotient tip/side was calculated. HLA DQ2/DQ8 and serum antibodies against transglutaminase were analysed.

    Results

    The mean number of IELs per 100 enterocytes (95% CI) in specimens was 14.7 (11.8-17.6) in the bulb, and 21.2 (17.0-25.5) in the second part of the duodenum (p<0.01). There was no difference in IEL count or distribution comparing patients carrying or lacking HLA DQ2/DQ8.

    Conclusions

    IEL count in non-celiac, HLA DQ2/DQ8 positive or negative patients is significantly lower in the bulb than in the second part of the duodenum. These findings implicate that the site of biopsy should be taken into account when considering duodenal lymphocytosis.

    Anemia and iron deficiency in inflammatory bowel disease: an open, prospective, observational study on diagnosis, treatment with ferric carboxymaltose and quality of life2013In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 48, no 9, p. 1027-1032Article in journal (Refereed)
    Abstract [en]

    Objective. Iron deficiency and anemia are being increasingly recognized as a complication of inflammatory bowel disease (IBD). The aim of this study was to observe, in a non-interventional way, how Swedish gastroenterologists adhere to guidelines in IBD outpatients treated with intravenous ferric carboxymaltose (FCM), and the result of treatment. Material and methods. Altogether 394 IBD patients (Crohns disease (CD) 60%, ulcerative colitis (UC) 40%) from 14 centers were included. Group A (n = 216) was observed from November 2008 and group B (n = 178) from March 2010. Time of observation ranged from 12 to 29 months. Results. S-Ferritin (mmol/l) and transferrin saturation (T-Sat; %) were recorded at baseline in 62% and 50% in group A. Median values for Hb, ferritin and T-Sat at baseline were 111 g/l, 10 mu mol/l and 10%, respectively, and 134 g/l, 121 mmol/l and 20% after iron treatment (p andlt; 0.001 for all three parameters). Similar results were found in group B. Approximately three-quarters of all patients had only one iron infusion during the study period. Median time to reinfusion was 6 (1-25) months. Only previously described infusion reactions occurred in 27 (7%) patients. Conclusions. Adherence to European guidelines was rather poor and needs to be improved. The effect on iron parameters of intravenous FCM was significant, and resulted in a ferritin level that indicates an effect on the iron stores. The effect was mostly sustained for a year since only one-quarter of the patients were given repeated iron infusions. No unforeseen safety concerns emerged during the observation period.

    Gender differences when using sedative music during colonoscopy2013In: Gastroenterology Nursing, ISSN 1042-895X, E-ISSN 1538-9766, Vol. 36, no 1, p. 14-20Article in journal (Refereed)
    Abstract [en]

    Colonoscopy is a procedure often experienced as uncomfortable and worrying. Music has been reported to reduce discomfort during colonoscopy; however, no study in a Swedish setting has been found. The purpose of this randomized controlled trial was to analyze the effects of sedative music on patients' experience of anxiety, pain, relaxation, and well-being during colonoscopy. Prior to colonoscopy, adult patients (n = 120), aged 18–80 years, were randomly assigned to either an intervention group (n = 60) who listened to sedative instrumental music with 60–80 beats per minute during the colonoscopy or a control group. After the colonoscopy, both groups completed a questionnaire on anxiety, the State Trait Anxiety Inventory, and an anxiety Visual Analogue Scale. Pain, relaxation, and well-being were also measured with Visual Analogue Scales. Women in the intervention group had a lower level of anxiety during the colonoscopy than those in the control group (p = .007) and well-being was significantly higher in the intervention group, especially among men, than in the controls (p = .006 and p = .025, respectively). Men in the intervention group were more relaxed during the colonoscopy than those in the control group (p = .065). Listening to sedative music decreased anxiety among women and increased well-being among men during colonoscopy.

    East-West gradient in the incidence of inflammatory bowel disease in Europe: the ECCO-EpiCom inception cohort2014In: Gut, ISSN 0017-5749, E-ISSN 1468-3288, Vol. 63, no 4, p. 588-597Article in journal (Refereed)
    Abstract [en]

    Objective The incidence of inflammatory bowel disease (IBD) is increasing in Eastern Europe. The reasons for these changes remain unknown. The aim of this study was to investigate whether an East–West gradient in the incidence of IBD in Europe exists.

    Design A prospective, uniformly diagnosed, population based inception cohort of IBD patients in 31 centres from 14 Western and eight Eastern European countries covering a total background population of approximately 10.1 million people was created. One-third of the centres had previous experience with inception cohorts. Patients were entered into a low cost, web based epidemiological database, making participation possible regardless of socioeconomic status and prior experience.

    Results 1515 patients aged 15 years or older were included, of whom 535 (35%) were diagnosed with Crohn's disease (CD), 813 (54%) with ulcerative colitis (UC) and 167 (11%) with IBD unclassified (IBDU). The overall incidence rate ratios in all Western European centres were 1.9 (95% CI 1.5 to 2.4) for CD and 2.1 (95% CI 1.8 to 2.6) for UC compared with Eastern European centres. The median crude annual incidence rates per 100 000 in 2010 for CD were 6.5 (range 0–10.7) in Western European centres and 3.1 (range 0.4–11.5) in Eastern European centres, for UC 10.8 (range 2.9–31.5) and 4.1 (range 2.4–10.3), respectively, and for IBDU 1.9 (range 0–39.4) and 0 (range 0–1.2), respectively. In Western Europe, 92% of CD, 78% of UC and 74% of IBDU patients had a colonoscopy performed as the diagnostic procedure compared with 90%, 100% and 96%, respectively, in Eastern Europe. 8% of CD and 1% of UC patients in both regions underwent surgery within the first 3 months of the onset of disease. 7% of CD patients and 3% of UC patients from Western Europe received biological treatment as rescue therapy. Of all European CD patients, 20% received only 5-aminosalicylates as induction therapy.

    Conclusions An East–West gradient in IBD incidence exists in Europe. Among this inception cohort—including indolent and aggressive cases—international guidelines for diagnosis and initial treatment are not being followed uniformly by physicians.

    Increased thrombin generation in splanchnic vein thrombosis is related to the presence of liver cirrhosis and not to the thrombotic event2014In: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 134, no 2, p. 455-461Article in journal (Refereed)
    Abstract [en]

    Background: In recent years there have been increasing evidence associating liver disease with hypercoagulability, rather than bleeding.

    Aims: To evaluate the haemostatic potential in patients with liver disease.

    Methods: We measured thrombin generation in the presence and absence of thrombomodulin in patients with portal vein thrombosis (PVT, n=47), Budd-Chiari syndrome (BCS, n=15) and cirrhosis (n=24) and compared the results to those obtained from healthy controls (n=21). Fifteen patients with PVT and 10 patients with BCS were treated with warfarin and were compared with an equal number of patients with atrial fibrillation matched for prothrombin time-international normalized ratio. We assessed resistance to thrombomodulin by using ratios [marker measured in the presence]/[marker measured in the absence of thrombomodulin].

    Results: There were no differences between patients with BCS, patients on warfarin treatment and controls. Cirrhotic patients generated more thrombin in the presence of thrombomodulin and exhibited thrombomodulin resistance compared with controls [p=0.006 for endogenous thrombin potential (ETP) and p<0.001 for peak thrombin. P<0.001 for both ratios ETP and peak] and patients with non-cirrhotic PVT (p=0.001, p=0.006, p<0.001, p<0.001 for ETP, peak, ratio ETP, ratio peak). The patients with cirrhotic PVT exhibited higher ETP (p=0.044) and peak (p=0.02) in the presence of thrombomodulin than controls, as well as thrombomodulin resistance (ETP ratio: p=0.001, peak ratio: p=0.001).

    Conclusions: Hypercoagulability and thrombomodulin resistance in patients with cirrhosis were independent of the presence of splanchnic vein thrombosis. The hypercoagulability in patients with cirrhotic PVT could have implications for considering longer treatment with anticoagulants in this group.

    Comparing 2D and 3D Magnetic Resonance Elastography Techniques in a Clinical Setting: Initial Experiences2014Conference paper (Other academic)
    Abstract [en]

    Purpose: It has been shown that liver fibrosis, and even cirrhosis, may be reversible in humans. For this reason there is a great need for the imminent introduction of non-invasive and clinically useful methods in order to monitor fibrosis in patients [1, 2]. A body of evidence points to the fact that MRE is a highly useful candidate towards this end [3]. However, before using such techniques more widely, it is important to verify that comparable physical measures are provided by alternative and clinically relevant MRE approaches. The aim of this pilot study was to compare 2D and 3D MRE, also known as MR Rheology, using a commercially available 2D system, with an acoustic transducer, and 3D MRE research system, with an electromagnetic transducer, with respect to liver stiffness and elasticity in patients with diffuse or suspected diffuse liver disease. Materials and Methods: Seven patients, referred to our hospital for evaluation of elevated serum alanine aminotransferase (ALT) and/or alkaline phosphatase (ALP) levels but without signs of cirrhosis on physical examination, were recruited from a previous study [4], and examined in the course of one day. Fibrosis staging from prior biopsy were gained from [4], see Table 1. The 3D MRE method included an active electromagnetic transducer generating waves at 56 Hz, and a 1.5 T Philips Achieva MR-scanner, with a phased array body coil (Sense TorsoXL, all 16 coil elements), GRE sequence parameters include; FOV = 320x256 mm2, matrix = 80x38, slice thickness = 4 mm, # slices = 9, FA = 15°, TR = 112 ms, TE = 9.21 ms, SENSE = 2. The 2D MRE method included a passive acoustic transducer generating waves at 60 Hz, and a 1.5 T GE 450W MR-scanner, with a phased array body coil (HD8 Torso, all 8 coil elements), GRE sequence parameters include; FOV = 440x440 mm2, matrix = 256x64, slice thickness = 10 mm, # slices = 4, FA = 30°, TR = 50 ms, TE = 21.7 ms, ASSET = 2. The transducers were on both systems placed on the anterior chest wall to the right of xiphoid process (patient in a supine position), the time between each MRE acquisition was dependent on how long it took to transfer the patient between the two MR systems in the hospital (<10 min) A region of interest (ROI) was placed in an appropriate single 10 mm slice acquired using the GE MR-scanner. A corresponding ROI for the Philips system, covering the same anatomical region, was placed over three slices (4 mm thickness each). This yielded a total cranio-caudal coverage of the ROIs equal to 10 mm (on the GE data) and 12 mm (on the Philips data). The mean and standard deviations of the stiffness (GE), elasticity (Philips) and Gabs,Elastic (Philips) were calculated. Gabs,Elastic is the absolute value of the shear modulus, which in principle is equivalent to the viscoelastic property, shear stiffness. In the 3D method the shear waves were obtained by applying the curl operator and using the Voigt rheological model to obtain shear elasticity maps [5, 6]. In the 2D method the GE system provided the stiffness maps. Statistics was performed using Mathematica 9. ROI drawing and quantification of the data from the GE system was performed using Sectra PACS IDS7, and ROI drawing and quantification of the data from the Philips system was performed using a custom software package implemented in ROOT, generously provided by R. Sinkus (Kings College, London, UK). Results: The measured values are presented in Table 1. Both elasticity and Gabs,Elastic correlates well with the stiffness measurement carried out in the GE system (Fig. 1), as was shown by the elasticity and stiffness correlation R2 = 0.96 (P < 0.001) slope = 1.08 (P < 0.001), intercept = 0.61 kPa (P = 0.08), Gabs,Elastic and stiffness correlation R2 = 0.96 (P < 0.001), slope = 0.95 (P< 0.001) intercept = 0.28 kPa (P = 0.43)

    Gene Expression and Thiopurine Metabolite Profiling in Inflammatory Bowel Disease: Novel Clues to Drug Targets and Disease Mechanisms?2013In: PLOS ONE, E-ISSN 1932-6203, Vol. 8, no 2Article in journal (Refereed)
    Abstract [en]

    Background and Aims

    Thiopurines are effective to induce and maintain remission in inflammatory bowel disease (IBD). The methyl thioinosine monophosphate (meTIMP)/6-thioguanine nucleotide (6-TGN) concentration ratio has been associated with drug efficacy. Here we explored the molecular basis of differences in metabolite profiles and in relation to disease activity.

    Methods

    Transcriptional profiles in blood samples from an exploratory IBD-patient cohort (n = 21) with a normal thiopurine S-methyltransferase phenotype and meTIMP/6-TGN ratios >20, 10.0–14.0 and ≤4, respectively, were assessed by hybridization to microarrays. Results were further evaluated with RT qPCR in an expanded patient cohort (n = 54). Additionally, 30 purine/thiopurine related genes were analysed separately.

    Results

    Among 17 genes identified by microarray-screening, there were none with a known relationship to pathways of purines/thiopurines. For nine of them a correlation between expression level and the concentration of meTIMP, 6-TGN and/or the meTIMP/6-TGN ratio was confirmed in the expanded cohort. Nine of the purine/thiopurine related genes were identified in the expanded cohort to correlate with meTIMP, 6-TGN and/or the meTIMP/6-TGN ratio. However, only small differences in gene expression levels were noticed over the three different metabolite profiles. The expression levels of four genes identified by microarray screening (PLCB2, HVCN1, CTSS, and DEF8) and one purine/thiopurine related gene (NME6) correlated significantly with the clinical activity of Crohn’s disease. Additionally, 16 of the genes from the expanded patient cohort interacted in networks with candidate IBD susceptibility genes.

    Conclusions

    Seventeen of the 18 genes which correlated with thiopurine metabolite levels also correlated with disease activity or participated in networks with candidate IBD susceptibility genes involved in processes such as purine metabolism, cytokine signaling, and functioning of invariant natural killer T cells, T cells and B cells. Therefore, we conclude that the identified genes to a large extent are related to drug targets and disease mechanisms of IBD.

    Pinworm infestation mimicking crohns' disease2013In: Case Reports in Gastrointestinal Medicine, ISSN 2090-6528, E-ISSN 2090-6536, Vol. 2013, article id 706197Article in journal (Refereed)
    Abstract [en]

    We here report a case of a young man who presented to his general practitioner with diarrhea. Inflammatory bowel disease was suspected and a colonoscopy showed aphthous lesions suggestive of Crohns' disease but biopsies revealed eggs of Enterobius vermicularis. When treated for this parasite, his symptoms were alleviated and a followup colonoscopy revealed a normal colon and distal ileum. Enterobius vermicularis is the most common parasite worldwide and has been attributed with many different presentations and pathologies. It is therefore necessary to maintain vigilance, even in high-income countries, in order to diagnose patients with one of the many atypical presentations of pinworms.

    Phosphatidylethanol Compared with Other Blood Tests as a Biomarker of Moderate Alcohol Consumption in Healthy Volunteers: A Prospective Randomized Study.2015In: Alcohol and Alcoholism, ISSN 0735-0414, E-ISSN 1464-3502, Vol. 50, no 4, p. 399-406Article in journal (Refereed)
    Abstract [en]

    AIM: It is generally agreed that traditional alcohol biomarkers lack in sensitivity to detect hazardous alcohol consumption. The present study was undertaken to evaluate the ability of phosphatidylethanol (PEth) and traditional alcohol markers to detect moderate alcohol consumption and to distinguish between moderate alcohol consumption and abstinence.

    METHODS: Forty-four subjects, 32 females and 12 males, were included in the study. They were randomized to alcohol abstention or to alcohol consumption. Female participants consumed 150 ml of red wine (equivalent to 16 g of alcohol) per 24 h and the male participants double the amount. The study lasted for 3 months. Blood samples were drawn at the start and at the end of the study period. Blood samples were analysed for PEth, carbohydrate-deficient transferrin (CDT), mean corpuscular volume (MCV), γ-glutamyltransferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT).

    RESULTS: ROC curves for the various biochemical markers were plotted in order to assess their ability to discriminate between abstention and moderate daily consumption of alcohol. PEth and CDT were the only markers with AUROCs significantly higher than 0.5, and PEth was detected in all participants randomized to alcohol consumption.

    CONCLUSION: PEth was the only marker that could detect moderate intake and the present results also indicate that PEth probably can distinguish moderate alcohol consumption from abstinence.

    Måttligt dagligt intag av alkohol gav inte upphov till leversteatos. Signifikant reduktion av LDL-kolesterol sågs däremot i prospektiv studie2012In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 109, no 5, p. 222-223Article in journal (Refereed)
    Abstract [sv]

    Leversteatos är den vanligaste leversjukdomen och orsakas hos de flesta av insulinresistens eller alkoholöverförbrukning.

    Enligt gällande riktlinjer kan så låg alkoholkonsumtion som 10 g/d vara förenlig med leversteatos.

    En nyligen genomförd randomiserad studie visar dock att en måttlig daglig konsumtion av rödvin inte orsakar vare sig leversteatos eller trans­aminaser överstigande övre referensgränsen. Däremot sågs en signifikant reduktion av LDL-kolesterol.

    Studiens resultat är förenliga med tidigare observationer rörande kardiovaskulär protektiv effekt av låg till måttlig alkoholkonsumtion. Även om det är osannolikt att sådan konsumtion orsakar steatos behövs ytterligare studier för att kartlägga andra långtidseffekter på levern.

    Histology of Microscopic Colitis - Review with Practical Approach for Pathologists2015In: Histopathology, ISSN 0309-0167, E-ISSN 1365-2559, Vol. 66, no 5, p. 613-626Article, review/survey (Refereed)
    Abstract [en]

    Microscopic colitis has emerged as a major cause of chronic watery non-bloody diarrhoea, particularly in elderly females. The term is used as an umbrella term to categorize a subgroup of colitides with distinct clinicopathologic phenotypes and no significant endoscopic abnormalities: Lymphocytic colitis is defined by an increased number of surface intraepithelial lymphocytes, collagenous colitis by a thickened collagen band underneath the surface epithelium. There is increased inflammation in the lamina propria, but only little or no crypt architectural distortion. Incomplete and variant forms showing less characteristic features have been reported under different names. Differential diagnosis mainly includes resolving infectious colitis and changes related to the intake of drugs such as non-steroidal anti-inflammatory drugs. Substantial clinical and histological overlap between lymphocytic and collagenous colitis has been described, raising the suspicion that the conditions are two histological manifestations of the same entity, possibly representing different manifestations during the disease course or different stages of disease development. In this review we provide a practical approach for pathologists with focus on diagnostic criteria and differential diagnosis, discuss recent insights into the pathogenesis of disease and the relation to classical chronic inflammatory bowel disease, i.e. Crohn's disease and ulcerative colitis.

    Effect of hypnotherapy and educational intervention on brain response to visceral stimulus in the irritable bowel syndrome2013In: Alimentary Pharmacology and Therapeutics, ISSN 0269-2813, E-ISSN 1365-2036, Vol. 37, no 12, p. 1184-1197Article in journal (Refereed)
    Abstract [en]

    Background Gut-directed hypnotherapy can reduce IBS symptoms, but the mechanisms underlying this therapeutic effect remain unknown. Aim To determine the effect of hypnotherapy and educational intervention on brain responses to cued rectal distensions in IBS patients. Methods Forty-four women with moderate-to-severe IBS and 20 healthy controls (HCs) were included. Blood oxygen level dependent (BOLD) signals were measured by functional Magnetic Resonance Imaging (fMRI) during expectation and delivery of high- (45mmHg) and low-intensity (15mmHg) rectal distensions. Twenty-five patients were assigned to hypnotherapy (HYP) and 16 to educational intervention (EDU). Thirty-one patients completed treatments and posttreatment fMRI. Results Similar symptom reduction was achieved in both groups. Clinically successful treatment (all responders) was associated with significant BOLD attenuation during high-intensity distension in the dorsal and ventral anterior insula (cluster size 142, P=0.006, and cluster size 101, P=0.005 respectively). Moreover HYP responders demonstrated a prepost treatment BOLD attenuation in posterior insula (cluster sizes 59, P=0.05) while EDU responders had a BOLD attenuation in prefrontal cortex (cluster size 60, P=0.05). Prepost differences for expectation conditions were almost exclusively seen in the HYP group. Following treatment, the brain response to distension was similar to that observed in HCs, suggesting that the treatment had a normalising effect on the central processing abnormality of visceral signals in IBS. Conclusions The abnormal processing and enhanced perception of visceral stimuli in IBS can be normalised by psychological interventions. Symptom improvement in the treatment groups may be mediated by different brain mechanisms. Clinical trial number: NCT01815164.

    Differences in the expression of hepatocyte growth factor in acute and chronic bowel inflammation - Implications for diagnosis?2013In: Advances in Bioscience and Biotechnology, ISSN 2156-8456, E-ISSN 2156-8502, Vol. 4, no 8A2, p. 33-42Article in journal (Refereed)
    Abstract [en]

    Background: Hepatocyte growth factor (HGF) acts as an acute phase protein with regenerative properties. HGF is produced systemically and locally during inflammation but exhibits decreased binding affinity to heparan sulphate proteoglycan (HSPG)/glycosaminoglycan during chronic inflammation. We previously observed a high faecal concentration and binding affinity of HGF to HSPG during acute gastroenteritis. High faecal concentrations of calprotectin and HGF have been reported in chronic inflammatory bowel disease (IBD).

    Methods: Stool samples from patients with ulcerative colitis in remission (n = 11) or exacerbation (n = 5), microscopic colitis (n = 11), colon cancer (n = 6), or acute gastroenteritis caused by Clostridium difficile (n = 20), as well as healthy controls (n = 7), were analysed for the presence of HGF by ELISA, surface plasmon resonance, SDS-PAGE, and Western blot. Then in two patients with ulcerative colitis exacerbation and C. difficile infection, the expression of HGF and calprotectin was studied in colonic biopsies.

    Results: The faecal concentration of HGF was significantly higher in patients with ulcerative colitis compared to the other groups. The binding affinity to dextran was lower in all groups compared to acute inflammation. HGF receptor binding was similar across groups. In a patient with concomitant C. difficile infection and distal ulcerative colitis, HGF was highly expressed in the part of the bowel unaffected by ulcerative colitis, but no expression was found at the site of chronic inflammation. In the patient with total colitis the biopsies showed low expression of HGF. The areas with chronic inflammation exhibited infiltrating calprotectin-stained neutrophils.

    Conclusion: HGF is produced locally during inflammation of the bowel. The HGF produced during acute inflammation or exacerbations of chronic inflammation by the unaffected area shows binding affinity to glucosaminoglycans. Measuring HGF binding in faeces and biopsies may be a tool for differentiating between acute and chronic bowel inflammation, which should be assessed thoroughly in future studies.

    Abstract [en]

    Introduction: The international normalized ratio (INR) is used to prioritize liver disease patients for transplantation. Previous studies have shown high interlaboratory variability in Quick-based INR determinations in samples of patients with liver disease. We assessed Owren-based INR reagents for analyzing INR in patients with liver disease. Further, we determined the difference between international sensitivity index (ISI) for patients on vitamin K antagonists (ISIVKA) and ISI for patients with liver disease (ISIliver). less thanbrgreater than less thanbrgreater thanPatients and Methods: Twenty patients with liver disease were included, 10 with INR 1.8-3.6 (group A1) and 10 with INR 1.2-1.5 (group C1). Plasma from these patients was analyzed for Owren-based INR in eight Swedish laboratories using either of following reagents: SPA+, Owrens PT or Nycotest PT. To determine ISI liver, the reference thromboplastin RBT/05 and additional 41 patients with liver disease and 20 normal controls were included. ISIVKA was determined according to the WHO procedure. The difference between the ISIVKA and ISIliver was calculated. less thanbrgreater than less thanbrgreater thanResults: The coefficients of variance for the Owren based INR methods were 6.2% in group A1, 3.9 % in group C1 and 5.3% for all patients. The difference between ISIVKA and ISIliver were -0.4%, -0.7% and -0.2% for SPA+, Owrens PT and Nycotest PT respectively. less thanbrgreater than less thanbrgreater thanConclusions: Interlaboratory variation in INR analyses according to Owren in patients with liver disease is low and the difference between ISIVKA and ISIliver is below 10% with this method. ISIVKA can therefore be used in the INR calibration, for the Owren reagents studied, when analyzing plasma from patients with liver disease.

    Lack of effect of methotrexate in budesonide-refractory collagenous colitis2013In: Clinical and Experimental Gastroenterology, E-ISSN 1178-7023, Vol. 6, p. 149-152Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    In most cases, collagenous colitis can be treated effectively with budesonide. However, some patients develop side effects or have chronic symptoms refractory to budesonide. This paper reports an open case series of patients intolerant or refractory to budesonide who were treated with methotrexate (MTX).

    METHODS AND PATIENTS:

    Nine patients (seven women) with a median (range) age of 62 (44-77) years were studied. Bowel movements were registered during 1 week prior to baseline and after 6 and 12 weeks' treatment, enabling calculation of the mean bowel movements/day. All patients underwent colonoscopy with biopsies before inclusion to confirm diagnosis. Open treatment with MTX was given 15 mg subcutaneously weekly for 6 weeks and was increased to 25 mg for a further 6 weeks if symptoms were unresponsive to the first 6 weeks' treatment. The endpoint was clinical remission, which was defined as a mean <3 stools/day and mean <1 watery stool/day/week at Week 12. The Short Health Scale was used at baseline and Week 12 to assess health-related quality of life.

    RESULTS:

    Five patients fulfilled the treatment according to the protocol and four patients discontinued the study after 3-6 weeks because of adverse events. No patient achieved clinical remission at Week 12. The mean stool frequency/day at baseline was 6.0 stools/day, thereof 5.4 watery stools/day and after 12 weeks treatment 6.4 stools/day, thereof 5.7 watery/day. No patient appreciated an improvement of health-related quality of life.

    CONCLUSION:

    Short-term treatment with MTX had no clinical effect in collagenous colitis patients intolerant or refractory to budesonide. Alternative therapies should be investigated in these patients.

    Association of non-alcoholic fatty liver disease with chronic kidney disease: a systematic review and meta-analysis2014In: PLoS Medicine, ISSN 1549-1277, E-ISSN 1549-1676, Vol. 11, no 7, p. e1001680-Article in journal (Refereed)
    Abstract [en]

    Background:Chronic kidney disease (CKD) is a frequent, under-recognized condition and a risk factor for renal failure and cardiovascular disease. Increasing evidence connects non-alcoholic fatty liver disease (NAFLD) to CKD. We conducted a meta-analysis to determine whether the presence and severity of NAFLD are associated with the presence and severity of CKD.Methods and Findings:English and non-English articles from international online databases from 1980 through January 31, 2014 were searched. Observational studies assessing NAFLD by histology, imaging, or biochemistry and defining CKD as either estimated glomerular filtration rate (eGFR) andlt;60 ml/min/1.73 m2 or proteinuria were included. Two reviewers extracted studies independently and in duplicate. Individual participant data (IPD) were solicited from all selected studies. Studies providing IPD were combined with studies providing only aggregate data with the two-stage method. Main outcomes were pooled using random-effects models. Sensitivity and subgroup analyses were used to explore sources of heterogeneity and the effect of potential confounders. The influences of age, whole-body/abdominal obesity, homeostasis model of insulin resistance (HOMA-IR), and duration of follow-up on effect estimates were assessed by meta-regression. Thirty-three studies (63,902 participants, 16 population-based and 17 hospital-based, 20 cross-sectional, and 13 longitudinal) were included. For 20 studies (61% of included studies, 11 cross-sectional and nine longitudinal, 29,282 participants), we obtained IPD. NAFLD was associated with an increased risk of prevalent (odds ratio [OR] 2.12, 95% CI 1.69-2.66) and incident (hazard ratio [HR] 1.79, 95% CI 1.65-1.95) CKD. Non-alcoholic steatohepatitis (NASH) was associated with a higher prevalence (OR 2.53, 95% CI 1.58-4.05) and incidence (HR 2.12, 95% CI 1.42-3.17) of CKD than simple steatosis. Advanced fibrosis was associated with a higher prevalence (OR 5.20, 95% CI 3.14-8.61) and incidence (HR 3.29, 95% CI 2.30-4.71) of CKD than non-advanced fibrosis. In all analyses, the magnitude and direction of effects remained unaffected by diabetes status, after adjustment for other risk factors, and in other subgroup and meta-regression analyses. In cross-sectional and longitudinal studies, the severity of NAFLD was positively associated with CKD stages. Limitations of analysis are the relatively small size of studies utilizing liver histology and the suboptimal sensitivity of ultrasound and biochemistry for NAFLD detection in population-based studies.Conclusion:The presence and severity of NAFLD are associated with an increased risk and severity of CKD.Please see later in the article for the Editors Summary. © 2014 Musso et al.

    Low-dose budesonide for maintenance of clinical remission in collagenous colitis: a randomised, placebo-controlled, 12-month trial2016In: Gut, ISSN 0017-5749, E-ISSN 1468-3288, Vol. 65, no 1, p. 47-56Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: This 1-year study aimed to assess low-dose budesonide therapy for maintenance of clinical remission in patients with collagenous colitis.

    DESIGN: A prospective, randomised, placebo-controlled study beginning with an 8-week open-label induction phase in which patients with histologically confirmed active collagenous colitis received budesonide (Budenofalk, 9 mg/day initially, tapered to 4.5 mg/day), after which 92 patients in clinical remission were randomised to budesonide (mean dose 4.5 mg/day; Budenofalk 3 mg capsules, two or one capsule on alternate days) or placebo in a 12-month double-blind phase with 6 months treatment-free follow-up. Primary endpoint was clinical remission throughout the double-blind phase.

    RESULTS: Clinical remission during open-label treatment was achieved by 84.5% (93/110 patients). The median time to remission was 10.5 days (95% CI (9.0 to 14.0 days)). The maintenance of clinical remission at 1 year was achieved by 61.4% (27/44 patients) in the budesonide group versus 16.7% (8/48 patients) receiving placebo (treatment difference 44.5% in favour of budesonide; 95% CI (26.9% to 62.7%), p<0.001). Health-related quality of life was maintained during the 12-month double-blind phase in budesonide-treated patients. During treatment-free follow-up, 82.1% (23/28 patients) formerly receiving budesonide relapsed after study drug discontinuation. Low-dose budesonide over 1 year resulted in few suspected adverse drug reactions (7/44 patients), all non-serious.

    CONCLUSIONS: Budesonide at a mean dose of 4.5 mg/day maintained clinical remission for at least 1 year in the majority of patients with collagenous colitis and preserved health-related quality of life without safety concerns. Treatment extension with low-dose budesonide beyond 1 year may be beneficial given the high relapse rate after budesonide discontinuation.

    Plasma lipoprotein particle concentrations in postmenopausal women with unstable coronary artery disease: Analysis of diagnostic accuracy using receiver operating characteristics2000In: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 247, no 1, p. 43-52Article in journal (Refereed)
    Abstract [en]

    Background.The contribution of plasma lipids to cardiovascular risk is usually evaluated by measuring plasma concentrations of total cholesterol, triglycerides and HDL cholesterol, and calculating LDL cholesterol concentration. We investigated plasma concentrations of apolipoproteins and lipoprotein particles in women with unstable coronary artery disease (CAD) to evaluate whether these, better than the routine lipid status, could differentiate women with and without coronary atherosclerosis.

    Methods. Blood samples for lipid analyses were collected from 119 angiographically examined postmenopausal 49–79-year-old women with unstable CAD, and from 101 age-matched controls. Mean plasma concentrations were compared and the discriminatory ability of the different variables were tested using receiver operating characteristics (ROC).

    Results. At coronary angiography 19% had normal vessels and 81% had coronary atherosclerosis. A disturbed triglyceride metabolism was the most pronounced lipid abnormality in women with unstable CAD and coronary atherosclerosis. ROC showed that none of the evaluated variables had a particularly high discriminatory power regarding unstable CAD or coronary atherosclerosis. The ratio cholesterol/HDL cholesterol was best with an ROC area of 0.79. Furthermore, the newer lipid variables, i.e. lipoprotein particles and apolipoproteins, were no better than the traditional variables.

    Conclusion. Lipoprotein changes reflecting a disturbed triglyceride metabolism are most pronounced in women with unstable CAD and coronary atherosclerosis. Lipoprotein particles and apolipoproteins alone were no better than lipids and lipoproteins in separating women with from those without coronary atherosclerosis. Our study does not support the measurement of apolipoproteins and lipoprotein particles on the basis of diagnostic accuracy alone.

    Separation of advanced from mild hepatic fibrosis by quantification of the hepatobiliary uptake of Gd-EOB-DTPA2013In: European Radiology, ISSN 0938-7994, E-ISSN 1432-1084, Vol. 23, no 1, p. 174-181Article in journal (Refereed)
    Abstract [en]

    Objectives

    To apply dynamic contrast-enhanced (DCE) MRI on patients presenting with elevated liver enzymes without clinical signs of hepatic decompensation in order to quantitatively compare the hepatocyte-specific uptake of Gd-EOB-DTPA with histopathological fibrosis stage.

    Methods

    A total of 38 patients were prospectively examined using 1.5-T MRI. Data were acquired from regions of interest in the liver and spleen by using time series of single-breath-hold symmetrically sampled two-point Dixon 3D images (non-enhanced, arterial and venous portal phase; 3, 10, 20 and 30 min) following a bolus injection of Gd-EOB-DTPA (0.025 mmol/kg). The signal intensity (SI) values were reconstructed using a phase-sensitive technique and normalised using multiscale adaptive normalising averaging (MANA). Liver-to-spleen contrast ratios (LSC_N) and the contrast uptake rate (KHep) were calculated. Liver biopsy was performed and classified according to the Batts and Ludwig system.

    Results

    Area under the receiver-operating characteristic curve (AUROC) values of 0.71, 0.80 and 0.78, respectively, were found for KHep, LSC_N10 and LSC_N20 with regard to severe versus mild fibrosis. Significant group differences were found for KHep (borderline), LSC_N10 and LSC_N20.

    Conclusions

    Liver fibrosis stage strongly influences the hepatocyte-specific uptake of Gd-EOB-DTPA. Potentially the normalisation technique and KHep will reduce patient and system bias, yielding a robust approach to non-invasive liver function determination.

    What do patients need to know? Living with inflammatory bowel disease2014In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 23, no 11-12, p. 1718-1725Article in journal (Refereed)
    Abstract [en]

    AIMS AND OBJECTIVES: To explore the need for knowledge as expressed by patients diagnosed with inflammatory bowel disease.

    BACKGROUND: Inflammatory bowel disease has a major impact on physical and emotional well-being, placing considerable demands on patients' management of daily activities. Although inflammatory bowel disease patients' level of knowledge about their disease has been previously studied, it is necessary to learn more about their self-expressed needs.

    DESIGN: The study was designed to explore patients' need for knowledge; therefore, an inductive method was chosen.

    METHODS: Thirty patients with inflammatory bowel disease were interviewed. Content analysis was used to describe their need for knowledge.

    RESULTS: The analysis generated three categories and eight subcategories: (1) knowledge related to the course of the disease (subcategories: understanding causal relationships between symptoms and the disease, complications related to the disease and understanding treatment), (2) knowledge related to managing everyday life (subcategories: behaviour that enhances well-being and managing social life) and (3) difficulty understanding and assimilating information (subcategories: shifting knowledge needs, help to understand information and reasons for wanting or not wanting knowledge).

    CONCLUSION: Knowledge needs were related to what to expect when living with inflammatory bowel disease in order to manage everyday life. There was a great variation in the need for knowledge, which was greatest immediately following diagnosis and during relapse.

    RELEVANCE TO CLINICAL PRACTICE: It is important for healthcare providers to ascertain the patients' individual knowledge needs and together with them formulate an individual care plan that gives the patient the necessary knowledge to manage their health and social life.

    Effect of oral diclofenac intake on faecal calprotectin2016In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 51, no 1, p. 28-32Article in journal (Refereed)
    Abstract [en]

    Background. NSAIDs are a known source of increased faecal calprotectin (FC) levels. Currently, there is a lack of knowledge about how long it takes for an increased FC level to return to normal after NSAID intake. Objective. The aim was to investigate how oral diclofenac intake affects FC levels and assess how long it takes for an increased FC level to return to normal after oral diclofenac intake. Material and methods. Thirty healthy volunteers received diclofenac 50 mg three times daily for 14 days. Participants provided a stool sample on Days 0, 2, 4, 7, 14 during intake and Days 17, 21, 28 after discontinuation. FC levels were then followed at 7-day intervals until normalization. Results. During diclofenac intake, eight participants (27%) had FC levels exceeding the upper limit of normal (median, 76 mu g/g; range, 60-958 mu g/g), corresponding to 8.3% of measurements. FC was not constantly increased and became normal in most participants during diclofenac intake. FC levels were on average significantly higher during intake (M = 9.5, interquartile range (IQR) = 13.4) than on baseline (M = 7.5, IQR = 0.0), p = 0.003. After discontinuation, two participants had increased FC on Days 17 and 21, respectively. No significant differences in FC levels were found between baseline and measurements after discontinuation. Two weeks after discontinuation, all participants had normal FC levels. Conclusions. Short-term oral diclofenac intake is associated with increased FC levels. However, the likelihood of an increased test result is low. Our results suggest that 2 weeks of diclofenac withdrawal is sufficient to get an uninfluenced FC test result.

    BackgroundRescue therapy with infliximab (IFX) has been proven effective in a steroid-refractory attack of ulcerative colitis (UC). The long-term efficacy is not well described. less thanbrgreater than less thanbrgreater thanAimTo present a retrospective study of IFX as rescue therapy in UC. Primary end points were colectomy-free survival at 3 and 12months. less thanbrgreater than less thanbrgreater thanMethodsIn this multicentre study, 211 adult patients hospitalised between 1999 and 2010 received IFX 5mg/kg as rescue therapy due to a steroid-refractory, moderate-to-severe attack of UC. Exclusion criteria were duration of current flare for andgt;12weeks, corticosteroid treatment for andgt;8weeks before hospitalisation, previous IFX therapy or Crohns disease. less thanbrgreater than less thanbrgreater thanResultsProbability of colectomy-free survival at 3months was 0.71 (95% CI, 0.64-0.77), at 12months 0.64 (95% CI, 0.57-0.70), at 3years 0.59 (95% CI, 0.52-0.66) and at 5years 0.53 (95% CI, 0.44-0.61). Steroid-free, clinical remission was achieved in 105/211 (50%) and 112/209 (54%) patients at 3 and 12months respectively. Of 75 colectomies during the first year, 48 (64%) were carried out during the first 14days, 13 (17%) on days 15-90 and 14 (19%) between 3 and 12months. There were three (1.4%) deaths during the first 3months. less thanbrgreater than less thanbrgreater thanConclusionsInfliximab is an effective rescue treatment, both short- and long-term, in a steroid-refractory attack of UC. Most IFX failures underwent surgery during the first 14days, which calls for studies on how to optimise induction treatment with IFX. Serious complications, including mortality, were rare.

    Soluble urokinase plasminogen activator receptor levels are associated with severity of fibrosis in nonalcoholic fatty liver disease2015In: Translational Research: The Journal of Laboratory and Clinical Medicine, ISSN 1931-5244, E-ISSN 1878-1810, Vol. 165, no 6, p. 658-666Article in journal (Refereed)
    Abstract [en]

    The identification of individuals with severe liver fibrosis among patients with chronic liver disease is of major importance when evaluating prognosis, potential risk for complications, and when deciding treatment strategies. Although percutaneous liver biopsy is still considered a "gold standard" for staging of liver fibrosis, attempts to find reliable noninvasive markers of liver fibrosis are frequent. Inflammation is essential for the progression of fibrosis. The urokinase plasminogen activator and its receptor have been associated with hepatic inflammation and fibrosis in mice. High serum concentrations of soluble urokinase plasminogen activator receptor (suPAR) are suggested to be involved in inflammation, tissue remodeling, and cancer metastasis. Here, we evaluated serum suPAR as a noninvasive test to detect liver fibrosis in 82 well-characterized patients with nonalcoholic fatty liver disease (NAFLD), and in 38 untreated patients with chronic hepatitis C virus (HCV) infection at the time of their first liver biopsy. suPAR levels were increased in chronic liver disease compared with blood donors (P < 0.001). Patients with HCV had higher suPAR concentrations than patients with NAFLD (P < 0.002). suPAR levels were associated with the severity of fibrosis, particularly in NAFLD, but did not correlate with inflammation. Regarding the performance in predicting severity of fibrosis, suPAR was essentially as good as other commonly used noninvasive fibrosis scoring systems. The results in HCV confirm previous observations. However, this is the first study to investigate suPAR as a biomarker in NAFLD, and the results indicate that suPAR may constitute a severity marker related to fibrosis and prognosis rather than reflecting inflammation.

    Analysis of single nucleotide polymorphisms in the region of CLDN2-MORC4 in relation to inflammatory bowel disease2013In: World Journal of Gastroenterology, ISSN 1007-9327, E-ISSN 2219-2840, Vol. 19, no 30, p. 4935-4943Article in journal (Refereed)
    Abstract [en]

    AIM: To investigate a possible genetic influence of claudin (CLDN) 1, CLDN2 and CLDN4 in the etiology of inflammatory bowel disease. METHODS: Allelic association between genetic regions of CLDN1, CLDN2 or CLDN4 and patients with inflammatory bowel disease, Crohns disease (CD) or ulcerative colitis were investigated using both a case-control study approach (one case randomly selected from each of 191 Swedish inflammatory bowel disease families and 333 controls) and a family-based study (463 non-Swedish European inflammatory bowel disease-families). A nonsynonymous coding single nucleotide polymorphism in MORC4, located on the same linkage block as CLDN2, was investigated for association, as were two novel CLDN2 single nucleotide polymorphism markers, identified by resequencing. RESULTS: A single nucleotide polymorphism marker (rs12014762) located in the genetic region of CLDN2 was significantly associated to CD (case-control allelic OR = 1.98, 95% CI: 1.17-3.35, P = 0.007). MORC4 was present on the same linkage block as this CD marker. Using the case-control approach, a significant association (case control allelic OR = 1.61, 95% CI: 1.08-2.41, P = 0.018) was found between CD and a nonsynonymous coding single nucleotide polymorphism (rs6622126) in MORC4. The association between the CLDN2 marker and CD was not replicated in the family-based study. Ulcerative colitis was not associated to any of the single nucleotide polymorphism markers. CONCLUSION: These findings suggest that a variant of the CLDN2-MORC4 region predisposes to CD in a Swedish population.

    Can participation in documentation influence experiences of involvement in care decision-making?2013In: Open Nursing Journal, E-ISSN 1874-4346, Vol. 7, no 1, p. 66-72Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION:

    Patients have the right to influence the care they receive, but their wish to participate in care decision-making is unclear.

    AIM:

    This study investigates whether participation in nursing documentation influences patient participation in care decision-making, mastery, self-esteem, empowerment and depressive feelings among adult in-patients with chronic disease.

    MATERIALS AND METHODOLOGY:

    Adult patients (n=39) with chronic diseases were randomized. The intervention group participated in nursing documentation. Upon departure, patients filled in questionnaires about participation in care decision-making, mastery, self-esteem, empowerment and depressive feelings.

    RESULTS:

    The majority of the patients preferred a collaborative or passive role regarding care decision-making. Lack of knowledge was one reason for non-participation. Having been diagnosed more than five years previously meant stronger empowerment.

    CONCLUSION:

    It is a challenge for nurses to find strategies to assess patients' wishes regarding participation in care decision-making. Nurses must support patients' knowledge of their disease and empowerment.

    Celiac disease and other autoimmune diseases in patients with collagenous colitis2013In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 48, no 8, p. 944-950Article in journal (Refereed)
    Abstract [en]

    Background and aims. Collagenous colitis (CC) is associated with autoimmune disorders. The aim of the present study was to investigate the relationship between CC and autoimmune disorders in a Swedish multicenter study. Methods. Patients with CC answered questionnaires about demographic data and disease activity. The patients files were scrutinized for information about autoimmune diseases. Results. A total number of 116 CC patients were included; 92 women, 24 men, median age 62 years (IQR 55-73). In total, 30.2% had one or more autoimmune disorder. Most common were celiac disease (CeD; 12.9%) and autoimmune thyroid disease (ATD, 10.3%), but they also had Sjogrens syndrome (3.4%), diabetes mellitus (1.7%) and conditions in skin and joints (6.0%). Patients with associated autoimmune disease had more often nocturnal stools. The majority of the patients with associated CeD or ATD got these diagnoses before the colitis diagnosis. Conclusion. Autoimmune disorders occurred in one-third of these patients, especially CeD. In classic inflammatory bowel disease (IBD), liver disease is described in contrast to CC where no cases occurred. Instead, CeD was prevalent, a condition not reported in classic IBD. Patients with an associated autoimmune disease had more symptoms. Patients with CC and CeD had an earlier onset of their colitis. The majority of the patients with both CC and CeD were smokers. Associated autoimmune disease should be contemplated in the follow-up of these patients.

    Monitoring of thiopurine metabolites - A high-performance liquid chromatography method for clinical use2013In: Journal of Pharmaceutical and Biomedical Analysis, ISSN 0731-7085, E-ISSN 1873-264X, Vol. 75, p. 145-152Article in journal (Refereed)
    Abstract [en]

    A high-performance liquid chromatography method capable of measuring thiopurine mono-, di-, and triphosphates separately in red blood cells (RBCs) was developed. RBCs were isolated from whole blood using centrifugation. Proteins were precipitated using dichloromethane and methanol. The thioguanine nucleotides (TGNs) were derivatised using potassium permanganate before analysis. Analytes were separated by ion-pairing liquid chromatography using tetrabutylammonium ions and detected using UV absorption and fluorescence. The method was designed for use in clinical trials. Ten patient samples were analysed to demonstrate clinical application and to establish pilot ranges for all analytes. less thanbrgreater than less thanbrgreater thanThe method measured thioguanosine mono-(TGMP), di-(TGDP), and triphosphate (TGTP), as well as methylthioinosine mono- (meTIMP), di- (meTIDP) and triphosphate (meTITP) in RBCs collected from patients treated with thiopurine drugs (azathioprine, 6-mercaptopurine, and 6-thioguanine). less thanbrgreater than less thanbrgreater thanLOQ was 0.3, 3, 2, 30, 30 and 40 pmol/8 x 10(8) RBC, for TGMP, TGDP, TGTP, meTIMP, meTIDP and meTITP, respectively. Between-day precision were below 14% for all analytes at all concentrations and samples were stable at 4 degrees C for 8 h after sampling.

    Novel assay to improve therapeutic drug monitoring of thiopurines in inflammatory bowel disease2014In: Journal of Crohn's & Colitis, ISSN 1873-9946, E-ISSN 1876-4479, Vol. 8, no 12, p. 1702-1709Article in journal (Refereed)
    Abstract [en]

    Background and aims: The thiopurines are widely used in the treatment of inflammatory bowel disease, but are limited by poor dose effect relationship. The objective was to assess the ability of a novel assay, determining the mono-, di-, and triphosphates, of thioguanine as well as methylthioinosine as individual metabolites in erythrocytes, to predict clinical outcome compared to a routine assay, determining metabolites as sums. Methods: Samples from 79 patients with Crohns disease or ulcerative colitis treated with azathioprine or mercaptopurine were analysed by both assays. Clinical status was determined by the Harvey-Bradshaw and Walmsley indices. The genotypes of thiopurine methyltransferase (TPMT) and inosine triphosphatase were determined. Results: TPMT wild-type patients with thioguanine nucleotide (TGN) levels below the cut-off level were more likely to have active disease when TGN was measured by the novel assay (p = 0.02), and when thioguanosine triphosphate (TGTP) was measured separately (p = 0.01). When TGN was measured by the routine assay the correlation was not evident (p = 0.12). Neither TGN levels nor TGTP correlated to disease activity in TPMT deficient patients. Patients with methyl thioinosine nucleotide (meTIN) levels above 1500 pmol/8 x 10less than^greater than8 RBCs were more likely to have active disease (p = 0.07). We observed good correlations between the mono-, di-, and triphosphates and their respective sums (R-2 greater than 0.88). Conclusions: The novel TGN assay was better in predicting clinical outcome compared to the routine assay, while determination of TGTP had no clinical advantage and TGTP ratio was not correlated to disease activity.

    Moderate hyperkalemia in hospitalized patients with cirrhotic ascites indicates a poor prognosis2013In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 48, no 3, p. 358-365Article in journal (Refereed)
    Abstract [en]

    Objective. Development of ascites in patients with liver cirrhosis is an ominous sign with a poor outcome. A liver transplantation must be considered, and it then becomes important to know if there are any factors indicating a worsened prognosis. Material and methods. We used official registers for a follow-up study of at least 5 years considering the prognosis of 155 prospectively recruited in-patients with cirrhotic ascites from medical units at nine Swedish university hospitals. All patients had undergone at least one diagnostic ascites tap, and had initially been questioned about background factors and physically examined according to a standardized case record form, followed by sampling of blood, urine, and ascites. Results. Death occurred within 1 year after inclusion in 53% of the cases, and was primarily liver-related in 70%. In a multivariable analysis, the two ordinary variables that showed the strongest correlation with risk of death were serum potassium and abdominal tenderness. All 22 patients with a serum potassium concentration of at least 4.8 mmol/L (maximum 5.8 mmol/L) died within 1 year after inclusion. Potassium concentration was related to renal function and potassium-saving drugs. Conclusion. This follow-up study of a prospectively recruited cohort of in-patients with cirrhotic ascites confirms their poor prognosis. Awareness of an elevated serum potassium value, which would reflect a threatened renal function, seems essential, because it may offer a simple way to identify cases with the worst prognosis. An area for further research should be to explore the significance of including serum potassium in prognostic models.

    Facilitating early recovery of bowel motility after colorectal surgery: a systematic review2014In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 23, no 1-2, p. 24-44Article, review/survey (Refereed)
    Abstract [en]

    AIMS AND OBJECTIVES:

    To determine how restored gastrointestinal motility can be accelerated after colorectal surgery.

    BACKGROUND:

    Regaining normal bowel functions after surgery is described as unexpectedly problematic. Postoperative ileus is expected after all surgery where the peritoneum is entered, and the length of surgery has little or no impact in terms of the duration of Postoperative ileus. There is some speculation about the best way to facilitate bowel motility after colorectal surgery.

    DESIGN:

    A systematic review.

    METHOD:

    The computerised databases Medline, Scopus and CINAHL were searched to locate randomised, controlled trials by using the following keywords: colorectal surgery, postoperative ileus, recovery of function and gastrointestinal motility. The systematic search was limited to studies published between January 2002-January 2012. Reference lists were also searched manually.

    RESULTS:

    A total of 34 randomised, controlled trials were included in the review. Recovery of gastrointestinal motility was accelerated when one of the following forms of treatment was administered: probiotics, early feeding in combination with multimodal regimens, pentoxifylline, flurbiprofen, valdecoxib, ketorolac, clonidine, ropivacaine, lidocaine or spinal analgesia. Gum chewing, preoperative carbohydrate loading, bisacodyl and Doppler-guided fluid management have an uncertain effect on bowel motility. The use of nonpharmacological interventions, intrathecal morphine, restricted fluid therapy and choline citrate yielded no significant acceleration in bowel motility.

    CONCLUSIONS:

    A multimodal treatment, where the use of morphine is restricted, seems to be the best way to accelerate the recovery of gastrointestinal bowel motility. However, more studies are required to optimise the multimodal protocol.

    RELEVANCE TO CLINICAL PRACTICE:

    The early return of bowel functions leads to quicker overall postoperative recovery, which may ease patient discomfort and decrease hospitalisation costs.

    Abdominal pain is associated with anxiety and depression scores in a sample of the general adult population with no signs of organic gastrointestinal disease2013In: Neurogastroenterology and Motility, ISSN 1350-1925, E-ISSN 1365-2982, Vol. 25, no 9, p. 741-E576Article in journal (Refereed)
    Abstract [en]

    Background Abdominal pain is common in the community, but only a subset meet diagnostic criteria for irritable bowel syndrome (IBS). Although anxiety and depression have been linked to IBS, the role of mood disturbances in the remainder with symptoms remains unclear. We aimed to study the associations between abdominal pain, anxiety, depression, and quality of life in the general population who were free of organic colonic disease by colonoscopy. Methods Two hundred and seventy-two randomly selected subjects from the general population, mean age 54 years (27-71), were clinically evaluated, had a colonoscopy and laboratory investigations to exclude organic gastrointestinal (GI) disease. All subjects completed GI symptom diaries for 1 week, the Rome II modular questionnaire, the Hospital Anxiety and Depression Scale, and Short Form 36. Key Results Twenty-two subjects were excluded due to organic disease; 1532 daily symptom records were available for analysis in the remainder. Thirty-four percent (n = 83) recorded at least one episode of abdominal pain on the diary. Twelve percent fulfilled Rome II criteria for IBS. Both anxiety and depression scores were higher in subjects who reported abdominal pain vs those who did not (P andlt; 0.0005 and P andlt; 0.0005). Anxiety and depression scores independently from IBS diagnosis (Rome II) predicted pain reporting and also correlated positively with pain burden. Quality of life scores were generally lower in subjects with abdominal pain. Conclusions andamp; Inferences Anxiety and depression are linked to functional abdominal pain, not only in subjects with IBS but also in otherwise healthy people with milder, subtle GI symptoms.

    Abstract [en]

    Background: Several brain imaging studies have demonstrated that visceral distensions activate the insular cortex but there is limited knowledge about which  subregions of the insula underpin the feeling of rectal urgency. An isobaric rectal balloon distension can be subdivided into the inflation phase when pressure is rising (rise) and a stable phase, when the pressure is constant. The rise phase is characterized by a more distinct sensation of urgency (Akervall et al., 1988). We aimed to study the BOLD response during the rise phase of a standardized rectal distension in subregions of the insula, in healthy controls.

    Method:Twenty right-handed female healthy volunteers (mean age 32.2 yrs, range 21-54) were included. Rectal pressure sensory thresholds were determined before functional Magnetic Resonance Imaging (fMRI) while the subjects were placed in the MR  scanner. Blood Oxygen Level Dependent (BOLD) signals were measured during the rise periods (6.6-7.2 sec) of 20 rectal distensions (45mmHg). Regions of interest (ROIs) included 10 insula subregions: Left (L) and right (R) anterior ventral, anterior dorsal, posterior ventral, posterior dorsal and mid insula. Results were reported as significant if peak p-value were, 0.05 with familywise error (FWE) correction in the ROIs.

    Results: The mean values for rectal sensory thresholds for first sensation, first sensation of urgency and maximum tolerable distension were 16 mmHg (SD 3.9), 28mmHg (SD 6.2) and 55 mmHg (SD 12.3), respectively. Complete fMRI data were available from 18 subjects. The rise period of the rectal distension generated significant BOLD activation in the right hemisphere in the anterior dorsal, anterior ventral, mid and posterior ventral parts of the insula. On the left side BOLD activity was generated in mid, posterior ventral and posterior dorsal parts of the insula but not in the anterior insula.
