  • Clinical trial : colectomy after rescue therapy in ulcerative colitis-3-year follow-up of the Swedish-Danish controlled infliximab study
  • 2010
  • Ingår i: Alimentary Pharmacology and Therapeutics. - Blackwell Publishing Ltd. - 0269-2813. ; 32:8, s. 984-989
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The long-term efficacy of infliximab as rescue therapy in steroid-refractory ulcerative colitis is not well described.Aim To examine the long-term efficacy of infliximab as a rescue therapy through a 3-year follow-up of a previous placebo-controlled trial of infliximab in acute steroid-refractory ulcerative colitis.Method In the original study, 45 patients were randomized to a single infusion of infliximab 5 mg/kg or placebo, and at 3 months, 7/24 patients given infliximab were operated vs. 14/21 patients given placebo. Three years or later, patients were asked to participate in a clinical follow-up.Results Another seven patients underwent colectomy during follow-up: five in the infliximab group and two in the placebo group. After 3 years, a total of 12/24 (50%) patients given infliximab and 16/21 (76%) given placebo (P = 0.012) had a colectomy. None of eight patients in endoscopic remission at 3 months later had a colectomy compared with 7/14 (50%) patients who were not in remission (P = 0.02). There was no mortality.Conclusion The benefit of rescue therapy with infliximab in steroid-refractory acute ulcerative colitis remained after 3 years. The main advantage of infliximab treatment occurred during the first 3 months, whereas subsequent colectomy rates were similar in the two groups. Mucosal healing at 3 months influenced later risk of colectomy.

  • Infliximab or cyclosporine as rescue therapy in hospitalized patients with steroid-refractory ulcerative colitis: : A retrospective observational study
  • 2012
  • Ingår i: Inflammatory Bowel Diseases. - Wiley-Blackwell. - 1078-0998. ; 18:2, s. 212-218
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Cyclosporine (CsA) or infliximab (IFX) are used as rescue therapies in steroid-refractory, severe attacks of ulcerative colitis (UC). There are no data comparing the efficacy of these two alternatives. less thanbrgreater than less thanbrgreater thanMethods: Outcome of rescue therapy was retrospectively studied in two cohorts of patients hospitalized due to steroid-refractory moderate to severe UC: 1) a Swedish-Danish cohort (n 49) treated with a single infusion of IFX; 2) an Austrian cohort (n 43) treated with intravenous CsA. After successful rescue therapy, maintenance immunomodulator treatment was given to 27/33 (82%) of IFX patients and to 31/40 (78%) of CsA patients. Endpoints were colectomy-free survival at 3 and 12 months. Kaplan-Meier and Cox regression models were used to evaluate the association between treatment groups and colectomy. less thanbrgreater than less thanbrgreater thanResults: At 15 days, colectomy-free survival in the IFX cohort was 36/49 (73%) versus 41/43 (95%) in the CsA cohort (P = 0.005), at 3 months 33/49 (67%) versus 40/43 (93%) (P = 0.002), and at 12 months 28/49 (57%) versus 33/43 (77%) (P = 0.034). After adjusting for potential confounding factors, Cox regression analysis yielded adjusted hazard ratios for risk of colectomy in IFX-treated patients of 11.2 (95% confidence interval [CI] 2.4-53.1, P = 0.002) at 3 months and of 3.0 (95% CI 1.1-8.2, P = 0.030) at 12 months in comparison with CsA-treated patients. There were no opportunistic infections or mortality. less thanbrgreater than less thanbrgreater thanConclusions: Colectomy frequencies were significantly lower after rescue therapy with CsA than with a single infusion of IFX both at 3 and 12 months follow-up. The superiority of CsA was seen principally during the first 15 days.

  • CARD15/NOD2 polymorphisms do not explain concordance of Crohn's disease in Swedish monozygotic twins
  • 2005
  • Ingår i: Digestive and Liver Disease. - 1590-8658. ; 37:10, s. 768-772
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. CARD15/NOD2 polymorphisms are associated with Crohn's disease. There is a high concordance for disease and disease phenotype in monozygotic twin pairs with Crohn's disease. Aim. We studied CARD15/NOD2 polymorphisms in a Swedish, population-based cohort of monozygotic twins with Crohn's disease to assess whether these variants explain disease concordance. Subjects and methods. Twenty-nine monozygotic twin pairs (concordant n = 9, discordant n = 20) with Crohn's disease and 192 healthy controls were investigated for the CARD15/NOD2 variants Arg702Trp, Gly908Arg and Leu1007fsinsC. Results. CARD15/NOD2 mutations were found in 5/38 (13%) twins with Crohn's disease, corresponding to a total allele frequency of 6.6%. Only 2/9 concordant twin pairs carried any of the variants and the remaining seven were wild type genotype. The total allele frequency was 4.4 times higher (95% confidence interval 1.0-21.5, p = 0.06) in concordant twins than in discordant ones, 11.1 % versus 2.5%. In healthy controls the total allele frequency was 2.6%. Conclusions. CARD15/NOD2 polymorphisms contribute but do not alone explain concordance of Crohn's disease in monozyptic twins and, at least in a Swedish population, other polymorphisms are required. The low occurrence of CARD 15/NOD2 mutations in the study and other Northern European populations suggests that these variants are of less importance in Northem Europe.

  • Inflammatory bowel disease in a Swedish twin cohort : A long-term follow-up of concordance and clinical characteristics
  • 2003
  • Ingår i: Gastroenterology. - 0016-5085. ; 124:7, s. 1767-1773
  • Tidskriftsartikel (refereegranskat)abstract
    • Background & Aims: In 1988, we reported the first twin study in inflammatory bowel disease. The aim of the current study was to follow up these twins regarding new cases of inflammatory bowel disease and Crohn's disease characteristics using the Vienna classification. Methods: The official Swedish population register and the cause of death register were used to search for the twins. All living patients were interviewed. Results: Three monozygotic twins earlier classified as healthy had been diagnosed with inflammatory bowel disease (ulcerative colitis, n = 2; Crohn's disease, n = :1). Retrospectively, all 3 were symptomatic at the original survey. This changed the pair concordance in monozygotic twins from 6.3% to 18.8% in ulcerative colitis and from 44.4% to 50.0% in Crohn's disease. A high degree of concordance regarding age at diagnosis, disease location at diagnosis and during the course, and disease behavior was found in concordant monozygotic twin pairs with Crohn's disease. Seven of 9 pairs were identical in 3 or more of these disease characteristics compared with an expected number of 1.5 (P = 0.000076). Conclusions: This study confirms that the genetic influence is stronger in Crohn's disease than in ulcerative colitis. A remarkable phenotype similarity within concordant pairs with Crohn's disease was found using the Vienna classification.

  • Increased Prevalence of Antibodies Against Dietary Proteins in Children and Young Adults With Cerebral Palsy
  • 2013
  • Ingår i: Journal of Pediatric Gastroenterology and Nutrition - JPGN. - Lippincott, Williams and Wilkins. - 0277-2116. ; 56:2, s. 233-238

    • Objectives: Undernourishment is common in children with cerebral palsy (CP), but the reasons are unknown. We previously reported elevated levels of immunoglobulin (Ig) A and IgG antibodies against gliadin (AGA) and tissue transglutaminase (tTG) in 99 children and young adults with CP without characteristic findings of gluten enteropathy in small bowel biopsies. Our aim was to perform a case-control study of IgG antibodies against other dietary antigens, AGA, anti-tTG, and IgE antibodies against wheat and gluten. less thanbrgreater than less thanbrgreater thanMethods: Sera from 99 cases with CP and 99 healthy, age-and sex-matched controls were analysed with fluorescence enzyme-linked immunosorbent assay for detection of IgG antibodies against beta-lactoglobulin, casein, egg white, IgG-and IgA-AGA, IgA-anti-tTG, and IgE antibodies against gluten and wheat. less thanbrgreater than less thanbrgreater thanResults: Compared with controls, the odds ratio in cases with CP for having elevated levels of IgG antibodies against beta-lactoglobulin was 17.0 (95% confidence interval [CI] 2.3-128), against casein 11.0 (95% CI 2.6-46.8), and against egg white 7.0 (95% CI 1.6-30.8). The IgE responses for wheat/gluten were generally low. The tetraplegic and dyskinetic CP subtypes had significantly higher frequencies of elevated levels for all of the tested antibodies except IgG against egg white, and IgA-anti-tTG. A significantly lower weight was seen in cases with CP with positive versus negative serology. less thanbrgreater than less thanbrgreater thanConclusions: Elevated levels of IgG against dietary antigens were more frequent in the CP group compared with controls, and particularly in the tetraplegic and dyskinetic CP subtypes with the most severe neurologic handicap and undernourishment. Hypothetically, malnourishment may cause increased intestinal permeability and thus immunization against dietary antigens.

  • Subclinical Inflammation with Increased Neutrophil Activity in Healthy Twin Siblings Reflect Environmental Influence in the Pathogenesis of Inflammatory Bowel Disease
  • 2013
  • Ingår i: Inflammatory Bowel Diseases. - 1078-0998. ; 19:8, s. 1725-1731
  • Tidskriftsartikel (refereegranskat)abstract
    • Background:The mechanisms behind increased fecal calprotectin (FC) in healthy relatives of patients with inflammatory bowel disease (IBD) are unknown. Our aims were to explore if there is a subclinical inflammation with increased neutrophil activity in healthy twin siblings in discordant twin pairs with IBD and to assess the influence of genetics in this context.Methods:Nuclear factor kappa B (NF-B) and neutrophil activity, based on myeloperoxidase (MPO) and FC, were analyzed in healthy twin siblings in discordant twin pairs with IBD and compared with healthy controls. NF-B and MPO were assessed by immunohistochemistry and FC by enzyme-linked immunosorbent assay.Results:In total, 33 of 34 healthy twin siblings were histologically normal. Increased NF-B was more often observed in healthy twin siblings in discordant twin pairs with Crohn's disease (13/18 [73%]) and with ulcerative colitis (12/16 [75%]) than in healthy controls (8/45 [18%]). MPO was more often increased in healthy twin siblings in discordant pairs with Crohn's disease (12/18 [67%]) than in healthy controls (11/45 [24%]) and FC more often in healthy twin siblings in discordant pairs with ulcerative colitis (14/21 [67%]) than in healthy controls (6/31 [19%]). Interestingly, the observed differences remained when healthy monozygotic and dizygotic twin siblings were analyzed separately.Conclusions:We observed increased NF-B, MPO, and FC in healthy twins in both monozygotic and dizygotic discordant pairs with IBD. These novel findings speak for an ongoing subclinical inflammation with increased neutrophil activity in healthy first-degree relatives.

  • Defining Clinical Criteria for Clinical Remission and Disease Activity in Collagenous Colitis
  • 2009
  • Ingår i: Inflammatory Bowel Diseases. - 1078-0998. ; 15:12, s. 1875-1881
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Collagenous colitis is a chronic inflammatory bowel disease accompanied mainly by nonbloody diarrhea. The objectives of treatment are to alleviate the symptoms and minimize the deleterious effects on health-related quality of life (HRQOL). There is still no generally accepted clinical definition of remission or relapse. The purpose of this study was to analyze the impact of bowel symptoms on HRQOL and accordingly suggest criteria for remission and disease activity based on impact of patient symptoms on HRQOL. Methods: The design was a cross-sectional postal survey of 116 patients with collagenous colitis. The main outcome measures were 4 HRQOL questionnaires: the Short Health Scale, the Inflammatory Bowel Disease Questionnaire, the Rating Form of IBD Patient Concerns, and the Psychological General Well-Being Index, and a 1-week symptom diary recording number of stools/day and number of watery stools/day. Results: Severity of bowel symptoms had a deleterious impact on patients HRQOL. Patients with a mean of greater than= 3 stools/day or a mean of greater than= 1 watery stool/day had a significantly impaired HRQOL compared to those with less than3 stools/day and less than 1 watery stool/day. Conclusions: We propose that clinical remission in collagenous colitis is defined as a mean of less than3 stools/day and a mean of less than 1 watery stool per clay and disease activity to be a daily mean of greater than= 3 stools or a mean of greater than= 1 watery stool.

  • Health-related quality of life is impaired in active collagenous colitis
  • 2011
  • Ingår i: DIGESTIVE AND LIVER DISEASE. - Elsevier Science B.V., Amsterdam. - 1590-8658. ; 43:2, s. 102-109
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The characteristic clinical symptoms of collagenous colitis are non-bloody diarrhoea, urgency and abdominal pain. Treatment is aimed at reducing the symptom burden and the disease impact on patients health-related quality of life. The objective of this study was to analyse health-related quality of life in patients with collagenous colitis. Methods: In a cross-sectional, postal HRQL survey, 116 patients with collagenous colitis at four Swedish hospitals completed four health-related quality of life questionnaires, two disease-specific (Inflammatory Bowel Disease Questionnaire and Rating Form of IBD Patient Concerns), and two generic (Short Form 36, SF-36, and Psychological General Well-Being, PGWB), and a one-week symptom diary. Demographic and disease-related data were collected. Results for the collagenous colitis population were compared with a background population controlled for age and gender (n = 8931). Results: Compared with a Swedish background population, patients with collagenous colitis scored significantly worse in all Short Form 36 dimensions (p andlt; 0.01), except physical function. Patients with active disease scored worse health-related quality of life than patients in remission. Co-existing disease had an impact on health-related quality of life measured with the generic measures. Lower education level and shorter disease duration were associated with decreased well-being. Conclusion: Health-related quality of life was impaired in patients with collagenous colitis compared with a background population. Disease activity is the most important factor associated with impairment of health-related quality of life. Patients in remission have a health-related quality of life similar to a background population.

  • Granulocyte, monocyte/macrophage apheresis for inflammatory bowel disease : the first 100 patients treated in Scandinavia
  • 2007
  • Ingår i: Scandinavian Journal of Gastroenterology. - Oslo : Taylor & Francis. - 0036-5521. ; 42:2, s. 221-227
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: Selective leukocyte apheresis is a new type of non-pharmacological treatment for patients with active ulcerative colitis and Crohn's disease. Preliminary data have indicated that this type of therapy is safe and efficacious, and large sham-controlled studies are currently in progress. In Scandinavia, a substantial number of patients with chronic inflammatory bowel disease have already received leukocyte apheresis on a compassionate use basis and the aim of this study was to report the clinical outcome and adverse events in the first patients treated. MATERIAL AND METHODS: Clinical details of the first consecutive 100 patients with inflammatory bowel disease treated with granulocyte, monocyte/macrophage (Adacolumn) apheresis in Scandinavia were prospectively registered. Median length of follow-up was 17 months, (range 5-30). RESULTS: The study population comprised 52 patients with ulcerative colitis, 44 patients with Crohn's disease and 4 patients with indeterminate colitis. In 97 patients the indication for Adacolumn treatment was steroid-refractory or steroid-dependent disease. Clinical remission was attained in 48% of the patients with ulcerative colitis, and an additional 27% had a clinical response to the apheresis treatment. The corresponding figures for patients with Crohn's disease were 41% and 23%, respectively. Complete steroid withdrawal was achieved in 27 out of the 50 patients taking corticosteroids at baseline. Adverse events were reported in 15 patients and headache was most frequently reported (n=7). CONCLUSIONS: Granulocyte, monocyte/macrophage apheresis treatment seems to be a valuable adjuvant therapy in selected patients with refractory inflammatory bowel disease. The risk for toxicity or severe adverse events appears to be low.

  • Celiac disease and other autoimmune diseases in patients with collagenous colitis
  • 2013
  • Ingår i: Scandinavian Journal of Gastroenterology. - Informa Healthcare. - 0036-5521. ; 48:8, s. 944-950
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
