- Background: From October 2018, adalimumab biosimilars could enter the European market. However, in some countries, such as Netherlands, high discounts reported for the originator product may have influenced biosimilar entry.Objectives: The aim of this paper is to provide a European overview of (list) prices of originator adalimumab, before and after loss of exclusivity; to report changes in the reimbursement status of adalimumab products; and discuss relevant policy measures.Methods: Experts in European countries received a survey consisting of three parts: 1) general financing/co-payment of medicines, 2) reimbursement status and prices of originator adalimumab, and availability of biosimilars, and 3) policy measures related to the use of adalimumab.Results: In May 2019, adalimumab biosimilars were available in 24 of the 30 countries surveyed. Following introduction of adalimumab biosimilars, a number of countries have made changes in relation to the reimbursement status of adalimumab products. Originator adalimumab list prices varied between countries by a factor of 2.8 before and 4.1 after loss of exclusivity. Overall, list prices of originator adalimumab decreased after loss of exclusivity, although for 13 countries list prices were unchanged. When reported, discounts/rebates on originator adalimumab after loss of exclusivity ranged from 0% to approximately 26% (Romania), 60% (Poland), 80% (Denmark, Italy, Norway), and 80–90% (Netherlands), leading to actual prices per pen or syringe between €412 (Finland) and €50 – €99 (Netherlands). To leverage competition following entry of biosimilar adalimumab, only a few countries adopted measures specifically for adalimumab in addition to general policies regarding biosimilars. In some countries, a strategy was implemented even before loss of exclusivity (Denmark, Scotland), while others did not report specific measures.Conclusion: Even though originator adalimumab is the highest selling product in the world, few countries have implemented specific policies and practices for (biosimilar) adalimumab. Countries with biosimilars on the market seem to have competition lowering list or actual prices. Reported discounts varied widely between countries.

- BACKGROUND: The mechanism behind the antiviral action of interferon (IFN) therapy in chronic hepatitis C virus (HCV) infection is not well understood, and, furthermore, few factors have been shown to be good predictors of a favourable response to IFN treatment in chronic HCV infection. METHODS: Freshly explanted liver cells and peripheral blood mononuclear cells (PBMC) from 80 patients with chronic HCV infection were used to study the capacity of IFN to induce the enzyme 2',5'-oligoadenylate synthetase (2'5'-AS) in vitro. The HCV genotype was determined in 53 patients. The induction of 2'5'-AS was correlated to the results of IFN-alpha treatment in 36 patients. RESULTS: Normalization of transaminases during IFN treatment was significantly associated with 2'5'-AS levels in liver cells cultured in the absence of IFN. A similar tendency, although not statistically significant, was found for IFN-induced levels of 2'5'-AS in liver cells. No such associations were found when PBMC were analysed. Six patients showed a sustained biochemical response. These six did not deviate significantly from the remaining patients with regard to base-line or IFN-induced levels of 2'5'-AS in liver cells or PBMC. Eradication of HCV RNA during IFN treatment did not correlate with 2'5'-AS levels in liver cells. Comparison of HCV genotype and clinical response showed that patients with genotype 3a had the most favourable outcome. No association was found between liver histology and treatment outcome. CONCLUSION: These data imply that direct effects of IFN on liver cells are of importance for the response to IFN treatment.

- BackgroundThere is an increasing interest in complementary and alternative medicine (CAM) in patients with chronic diseases, including those with inflammatory bowel disease (IBD). Patients may turn to CAM when conventional therapies are inadequate or associated with side effects for symptomatic relief or to regain control over their disease. The objectives were to explore CAM use and perceived effects in IBD patients in comparison with a control group.MethodsA cross-sectional, multicenter, controlled study was carried out. IBD patients were invited from 12 IBD clinics in Sweden. Controls were selected randomly from a residence registry. A study-specific questionnaire was used for data collection.ResultsOverall, 48.3% of patients with IBD had used some kind of CAM during the past year compared with 53.5% in controls (P=0.025, adjusted for age, sex, geographic residence, and diet). The most frequently used CAM among IBD patients was massage (21.3%), versus controls (31.4%) (adjusted P=0.0003). The second most used CAM was natural products, 18.7% in IBD patients versus 22.3% of the controls (unadjusted P=0.018). In all, 83.1% of the patients experienced positive effects from CAM and 14.4% experienced negative effects.ConclusionOverall, 48.3% of Swedish IBD patients used some kind of CAM and controls used CAM significantly more. Natural products were used by one-fifth of the patients and even more by controls. This is notable from a patient safety perspective considering the possible risks of interactions with conventional medication. In all, 40% of the patients reported adverse events from conventional medicine. Patients experienced predominantly positive effects from CAM, and so did controls.

- BACKGROUND: The cholera toxin B subunit ameliorates experimentally induced colitis in mice. In humans, cholera toxin B subunit has never been tested in the treatment of Crohn's disease (CD). AIM: To evaluate the safety and efficacy of treatment with recombinant cholera toxin B subunit of patients with CD. METHODS: An open-label, multicentre, nonrandomized trial including 15 patients with mild/moderate CD. Patients received an oral solution of 5 mg recombinant cholera toxin B subunit three times weekly for 2 weeks. Reduction in CD Activity Index (CDAI) with >100 between baseline and days 15, 29, 42 and 70 defined clinical response. Patients with CDAI score < or = 150 were defined as being in remission. RESULTS: A significant decrease in CDAI score was observed. Response rates were 40% in the full analysis set and 42% in the per protocol analysis. Two patients receiving adjuvant treatment after day 29 were excluded, after which 40% were in remission at 4 weeks and 30% at 8 weeks post-treatment. Mild side effects (arthralgia, headache and pruritus) were seen in 33% of patients. CONCLUSIONS: Treatment with recombinant cholera toxin B subunit was safe. Approximately 40% of patients with active CD responded to treatment. Randomized studies are needed to establish the clinical efficacy of recombinant cholera toxin B subunit.

- 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.

- Anemia is a common complication of inflammatory bowel diseases. An international working party has formed and developed guidelines for evaluation and treatment of anemia and iron deficiency that should serve practicing gastroenterologists. Within a total of 16 statements, recommendations are made regarding diagnostic measures to screen for iron- and other anemia-related deficiencies regarding the triggers for medical intervention, treatment goals, and appropriate therapies. Anemia is a common cause of hospitalization, prevents physicians from discharging hospitalized patients, and is one of me most frequent comorbid conditions in patients with inflammatory bowel disease. It therefore needs appropriate attention and specific care. Copyright © 2007 Crohn's & Colitis Foundation of America, Inc.

- Inflammatory bowel disease (IBD) can be treated effectively by anti-tumour necrosis factor (TNF) therapy. We set out to investigate the unclear immunoregulatory mechanisms of the treatment. Thirty-four patients with IBD treated with anti-TNF were included. Lymphocytes from peripheral blood and intestinal biopsies were analysed by flow cytometry. Regulation of antigen-stimulated proliferation was analysed by blocking of interleukin (IL)-10, transforming growth factor (TGF)-beta or depletion of CD25+ cells in peripheral blood mononuclear cell cultures. No changes in CD4+CD25+, CD25+TNF-RII+ or CD4+CD25+forkhead box protein 3 (FoxP3+) T cells could be observed in peripheral blood after, in comparison to before, 6 weeks of treatment. The suppressive ability of CD4+CD25+ cells did not change. There was an initial decrease of CD4+CD25+ cells in intestinal mucosa after 2 weeks of treatment, followed by an increase of these cells from weeks 2 to 6 of treatment (P < 0.05). This was accompanied by an increased percentage of CD69+ cells among these cells after 6 weeks of treatment compared to before treatment (P < 0.01). There was also an increase of mucosal T helper type1 cells from weeks 2 to 6 (P < 0.05). In addition, CD25+TNF-RII+ cells in the mucosa were decreased after 6 weeks of treatment compared to before treatment (P < 0.05). Before treatment, peripheral blood mononuclear cell baseline proliferation was increased when IL-10 was blocked (P < 0.01), but not after. In CD25+ cell-depleted cultures proliferation increased after treatment (P < 0.05). Our data indicate that anti-TNF treatment leads to an induction of effector T cells. Anti-TNF therapy has no significant impact on regulatory T cells in IBD, although the composition of regulatory T cell subsets may change during treatment.

- Background and aims: Oral aminosalicylates are well established in the treatment of active mild/moderate ulcerative colitis (UC) when the disease is extensive (that is, beyond the splenic flexure). The majority of clinical symptoms relate to disease activity in the distal part of the colon and therefore this study was designed to investigate if adding a mesalazine enema to oral mesalazine has additional benefit for patients with extensive mild/moderate active UC. Methods: A randomised double blind study was performed in 127 ambulatory patients. All received 4 g/day (twice daily dosing) oral mesalazine for eight weeks. During the initial four weeks, they additionally received an enema at bedtime containing 1 g of mesalazine or placebo. Disease activity was assessed using the ulcerative colitis disease activity index, with clinical and endoscopic signs at four and eight weeks. Results: Remission was obtained in 44% (95% confidence interval (CI) 31%, 58%) of the mesalazine enema group (Me) and in 34% (95% CI 21%, 49%) of the placebo enema group (Pl) at four weeks (p = 0.31) and in 64% (95% CI 50%, 76%) of the Me group versus 43% (95% CI 28%, 58%) of the Pl group at eight weeks (p = 0.03). Improvement was obtained in 89% (95% CI 78%, 96%) of the Me group versus 62% (95% CI 46%, 75%) of the Pl group at four weeks (p = 0.0008) and in 86% (95% CI 75%, 94%) of the Me group versus 68% (95% CI 53%, 81%) of the Pl group at eight weeks (p = 0.026). Conclusion: In patients with extensive mild/moderate active UC, the combination therapy is superior to oral therapy. It is safe, well accepted, and may be regarded as firstline treatment.
