- Introduction: Fecal calprotectin (FC) is anoninvasive tool for examining response to biologics in inflammatory boweldisease (IBD), but its performance in relation to other novel fecal markers of various cellular origins is unknown.Methods: We performed a prospective multicenter cohort study and included patients with active IBD who provided a fecal sample at initiation of biological therapy. Levels of FC, myeloperoxidase (MPO), human neutrophil lipocalin (HNL), and eosinophil-derived neurotoxin (EDN) were analyzed and related to clinical remission status at 3 months. Changes in levels of markers at 3 months were calculated, and the impact of concomitant use of corticosteroids at baseline was estimated.Results: In patients achieving clinical remission (n = 27), a decrease in levels of FC (P = 0.005), MPO (P < 0.001), HNL (P < 0.001), and EDN (P < 0.001) was observed, whereas no significant decrease was seen in patients not achieving remission (n = 39). There was a significant difference in the change in the level of MPO (P = 0.01) and HNL (P = 0.02) between patients achieving clinical remission and those who did not, but changes in FC and EDN could not differentiate between these groups. Patients with concomitant systemic corticosteroids at inclusion had lower levels of HNL (P = 0.01) and EDN (P < 0.001) at baseline, compared with patients without corticosteroids.Discussion: Fecal MPO, HNL, and EDN are all promising biomarkers for assessing the treatment outcome of biologics in patients with IBD. Fecal levels of EDN and HNL are significantly affected by corticosteroids indicating a greater sensitivity to the effects of corticosteroids compared with levels of FC and MPO.

- OBJECTIVE: Health-related quality of life (HRQoL) is an important measure of inflammatory bowel disease (IBD) health outcome. The Inflammatory Bowel Disease Questionnaire (IBDQ) comprising 32 items grouped into four dimensions is a widely used IBD-specific HRQoL instrument. The purpose of this study was to evaluate the validity, reliability and responsiveness of the Swedish translation of the IBDQ in patients with Crohn's disease (CD). MATERIAL AND METHODS: Four hundred and forty-eight patients with CD completed the IBDQ and three other HRQoL questionnaires (Rating Form of IBD Patient Concerns; Short Form-36; and the Psychological General Well-Being Index) in connection with their regular visit at the outpatient clinic. Disease activity was assessed by the physician on a 4-point Likert scale. Thirty-two patients who were stable in remission completed the questionnaires a second time, 4 weeks later. A total of 418 patients repeated all measurements after 6 months. RESULTS: The dimensional scores were highly correlated with other measures of corresponding aspects of HRQoL and were significantly better in remission than in relapse. High test-retest correlations indicated good reliability. Responsiveness was confirmed in patients whose disease activity changed over time. However, high correlations between the dimensions, poor correlations between items within each dimension, and factor analysis all indicated that the original grouping of the items is not valid for Swedish CD patients. CONCLUSIONS: Although the Swedish IBDQ has good external validity, reliability and responsiveness for patients with CD, our results did not support the original grouping of the items.

- BACKGROUND: The Crohn's Disease Activity Index (CDAI) has become the gold standard for assessment of disease activity in CD. This study investigated the relationship between CDAI and the physicians' global assessment of disease activity (PGA) and whether different demographic and disease-related factors predict the outcome.METHODS: Multiple linear regression analysis was used to investigate the relationship between CDAI and PGA obtained from 405 CD patients. Predictors of the CDAI and the PGA outcome were identified.RESULTS: The correlation between CDAI and PGA was moderate. In patients with CDAI >150, 72% of the total score were derived from the subjective variables. The regression coefficients were not significant for 3 of the CDAI variables. In regression analysis, C-reactive protein (CRP), stenosis, smoking, bowel resection, concomitant disease, and gender predicted the CDAI outcome. The PGA outcome was predicted only by CRP, stenosis, and fistula.CONCLUSIONS: The correlation between CDAI and PGA was moderate and the subjective variables had a high impact on CDAI. Factors with no obvious relation to inflammatory activity predicted the outcome of CDAI, but not PGA. In trials of CD therapies, separation of subjective (symptoms, well-being) from objective (endoscopy, inflammatory markers) variables should be considered in the assessment of disease activity.

- BACKGROUND: Health-related quality of life (HRQoL) is an essential part of inflammatory bowel disease (IBD) assessment. The Short Health Scale (SHS), an HRQoL questionnaire in which the patients rate the disease impact on 4 important aspects of subjective health (symptoms, function, worry, and general well-being) was demonstrated in a previous study to be valid, reliable, and responsive in patients with ulcerative colitis. The present study evaluates the SHS in patients with Crohn's disease (CD). METHODS: In all, 367 CD patients completed the SHS and 4 other HRQoL questionnaires (IBDQ, SF-36, RFIPC, and PGWB) at their regular outpatient visits. Then 330 patients completed the questionnaires at a second visit 6 months later. In addition, reliability data were obtained from repeat measurements 4 weeks after the first visit in 40 patients stable in remission. RESULTS: Patients in remission scored better on all 4 questions than those with active disease (P < 0.001). All 4 questions were strongly correlated with the corresponding dimensions of the other HRQoL questionnaires (r(s) = 0.74-0.83). Reliability was confirmed with strong test-retest correlations (r(s) = 0.69-0.82) and intraclass correlation coefficients (0.66-0.77). Patients who changed from remission to active disease or vice versa showed a significant change in all 4 SHS scores (P < 0.005). CONCLUSIONS: SHS is a valid, reliable and responsive HRQoL instrument also in patients with CD. It is easily completed by the patient and requires no further calculation by the investigator. SHS gives a comprehensive overview of the main aspects of the patient's subjective health perception and is a useful tool in both clinical practice and clinical studies.

- 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 < 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. (C) 2010 Published by Elsevier Ltd on behalf of Editrice Gastroenterologica Italiana S.r.l.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The effectiveness of golimumab in Crohn's disease (CD) is largely unknown as it is not approved for the treatment of the disease. We aimed to identify the population of CD patients treated with golimumab in Sweden, to assess the effectiveness of golimumab (defined as the drug retention rate), and to identify predictors of drug discontinuation.METHODS: Patients with CD who received at least one injection of golimumab were identified through the Swedish National Quality Registry for Inflammatory Bowel Disease, which includes prospectively collected clinical information. Cox regression models were used to identify predictors of golimumab discontinuation.RESULTS: The study cohort involved 94 patients of whom the majority (96.8%) had previously discontinued at least one anti-tumour necrosis factor (anti-TNF) agent. The drug retention rate at 12 weeks was 85.1%. Predictors of golimumab discontinuation at 12 weeks were previous surgery (adjusted HR = 7.52, 95% CI: 1.12-50.36), concomitant corticosteroid use at baseline (adjusted HR = 5.70, 95% CI: 1.13-28.68) and female sex (adjusted HR = 6.59; 95% CI: 1.04-41.62). The median duration of follow-up was 89 (IQR: 32-158) weeks. The drug retention at the most recent follow-up was 35.1%. Predictors of golimumab discontinuation at the most recent follow-up were corticosteroid use at baseline (adjusted HR = 2.60, 95% CI: 1.17-5.79) and female sex (adjusted HR = 2.24; 95% CI: 1.19-4.23).CONCLUSION: Patients with CD treated with golimumab were a treatment-refractory group. Despite this, more than one-third of the patients appeared to have had clinical benefit after a median follow-up of more than 1.5 years.

- Lay Summary: The incidence rate of serious infection among inflammatory bowel disease patients did not increase with anti-TNF therapy compared with 1 year before treatment start. A decrease in incidence rate could be seen more than 1 year after initiation of anti-TNF.Background: Serious infections have been observed in patients with inflammatory bowel disease (IBD) on anti-TNF use-but to what extent these infections are due to anti-TNF or the disease activity per se is hard to disentangle. We aimed to describe how the rates of serious infections change over time both before and after starting anti-TNF in IBD.Methods: Inflammatory bowel disease patients naive to anti-TNF treatment were identified at 5 centers participating in the Swedish IBD Quality Register, and their medical records examined in detail. Serious infections, defined as infections requiring in-patient care, the year before and after the start of anti-TNF treatment were evaluated.Results: Among 980 patients who started their first anti-TNF therapy between 1999 and 2016, the incidence rate of serious infections was 2.19 (95% CI,1.43-3.36) per 100 person years the year before and 2.11 (95% CI, 1.33-3.34) per 100 person years 1 year after treatment start. This corresponded to an incidence rate ratio 1 year after anti-TNF treatment of 0.97 (95% CI, 0.51-1.84). Compared with before anti-TNF therapy, the incidence of serious infection was significantly decreased more than 1 year after treatment (incidence rate ratio 0.56; 95% CI, 0.33-0.95; P = .03).Conclusions: In routine clinical practice in Sweden, the incidence rate of serious infection among IBD patients did not increase with anti-TNF therapy. Instead, serious infections seemed to decrease more than 1 year after initiation of anti-TNF treatment.

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Adverse events (AE) leading to discontinuation or dose-reduction of thiopurine therapy (TP) occur in 9-28% of patients with inflammatory bowel disease. 6-Thioguanine (6-TG) has been proposed as an alternative treatment in patients intolerant for azathioprine (AZA), but some concerns have been raised about drug safety. Methods: We evaluated in a prospective manner the tolerance and efficacy of 6-TG in 23 Crohns disease (CD) patients (13 men, median age 41 (19-65) years) with prior intolerance (n = 18) or resistance (It = 5) to AZA and/or 6-mercaptopurine (6-MP). In addition, eight patients had tried mycophenolate mofetil. Seventeen patients (74%) had undergone intestinal resection, often several times. Results: Patients were treated with a median daily dose of 40 mg 6-TG (range 20-60) for 259 (15-2272) days. Seven of 13 patients (54%) with active disease went into remission after 8 (4-26) weeks. Sixteen patients (70%) experienced AE that lead to discontinuation (n=10) after 85 (15-451) days or dose reduction (n=6) after 78 (10-853) days. Ten of 18 patients (56%) with prior TP-intolerance discontinued 6-TG treatment due to AE compared to none of five patients with TP-resistance (p=0.046). Of 13 patients that tolerated 6-TG, eight discontinued the drug due to therapeutic failure (n=5) or safety concerns (n=3). Eight patients (35%) continued treatment beyond 12 months. There was no significant difference in maximum thioguanine nucleotide levels between patients with AE leading to discontinuation/dose reduction and patients without AE, 652 (99-2488) vs. 551 (392-1574) pmol/8 x 10(8) RBC; p=0.80. Conclusions: In this cohort of CD patients with severe disease failing traditional thiopurine treatment, a small fraction (22%) had long-term benefit of 6-TG-treatment. 6-TG therapy seems to offer a limited therapeutic gain for patients intolerant to both AZA and 6-MP and other treatment options should be considered.

- Background similar to Patients with inflammatory bowel disease (IBD) often complain of fatigue. Aim similar to To investigate the prevalence and characteristics of fatigue among IBD out-patients in Scandinavia and to provide normative values for fatigue in IBD patients. Methods similar to A cross-sectional study was conducted on 425 IBD patients from six out-patient centres in Denmark, Norway and Sweden. Fatigue was measured using the Multidimensional Fatigue Inventory. The patients were also screened for anaemia and iron deficiency. Each centre included approximately 5% of their IBD cohort. The patients were enrolled consecutively from the out-patient clinics, regardless of disease activity and whether the visit was scheduled. The fatigue analysis was stratified for age and gender. Results similar to Using the 95th percentile of the score of the general population as a cut-off, approximately 44% of the patients were fatigued. When comparing the IBD patients with disease activity to the IBD patients in remission, all dimensions of fatigue were statistically significant (P less than 0.05). Being anaemic or iron deficient was not associated with increased fatigue. Being a male patient with ulcerative colitis treated with corticosteroids was a strong determinant for increased fatigue. The normative ranges for IBD fatigue were calculated. Conclusions similar to Fatigue in IBD is common regardless of anaemia or iron deficiency. Fatigue in IBD is most marked for patients less than60 years of age. Stratifying for gender and age is necessary when analysing fatigue, as fatigue is expressed differently between groups.

- 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.
