Relationship Of

Mesalazine is widely used in the treatment of inflammatory bowel disease. Little is known about the doseresponse relationship and about possible dose related side effects. In ulcerative colitis higher dosages of mesalazine (3 g) are more effective in maintaining a remission than lower dosages (1.5 g). In mild to moderately active ulcerative colitis, studies also indicate that higher dosages might be more effective in inducing remission. Dose-comparing studies in Crohn's disease are even more sparse, but the available results indicate higher efficacy at higher dose levels.None of the known side effects of mesalazine are clearly dose-related. A pH-dependent release system, however, can cause a sudden release of high doses of mesalazine. Consequent peak levels in serum have been implicated in mesalazine induced nephrotoxicity. In conclusion, despite the current practice of using increasing dosages of mesalazine in inflammatory bowel disease, both efficacy and safety have been established tentatively.

Inflammatory Bowel

There are two forms of 5-aminosalicylic acid (5-ASA) drug delivery. First, a pro-drug form in which 5-ASA, the active principal, is attached to a c.arrier molecule and released in the intestine by bacterial cleavage. An example of this is sulfasalazine, originally developed in the 1940s and found to be effective, cheap, but limited by side effects due to the sulfapyridine component. The second drug delivery system depends on an enteric coating for delayed pH-dependent release or for a timed-released mechanism. 5-ASA inhibits 5-lipoxygenase, modulates leukocyte function and inhibits soluble mediator release, and is an effective scavenger action of free oxygen radicals, the relative importance of which is unknown. The multiplicity of action is probably its strength because drugs that have only one of these actions are relatively ineffective in inflammatory bowel disease. 5-ASA compounds are effective in treating mild to moderate acute ulcerative colitis and in maintaining remission, and are equivalent to sulfasalazine in this regard. 5-ASA used topically in enema or suppository form is highly efficient in both acute disease and in maintaining remission. 5-ASA is also effective in active Crohn’s disease, but not as effective as in maintenance therapy compared with ulcerative colitis. The pro-drugs tend to have more side effects. Slow release compounds are well tolerated with few side effects, allowing increases to effective dosage. In patients intolerant of sulfasalazine, switching to a 5-ASA preparation usually results in tolerance and therapeutic benefit, with an occasional allergic reaction to the 5-ASA molecule limiting its use.

Abstract Background Medication nonadherence in inflammatory bowel disease (IBD) is common and has a negative impact on disease outcome. It is currently not clear whether in patients with IBD, the opinions, beliefs and attitudes towards medicines determine an adequate therapeutic adherence. Our aim was to assess what the real influence of medication opinions is on IBD patients adherence. Methods Patients attending a tertiary hospital IBD outpatient clinic were enrolled. They filled the BMQ (Beliefs about Medication Questionnaire): a 18-item standardized scale assessing specific opinions about medication that a person is taking and beliefs about the potential for harm and overuse of medication in general. Pharmacy refill data were checked for the previous 3 months and their medication possession ratios (MPR) were calculated. Nonadherence was defined as MPR<0.8.Ethical approval was obtained. Results We analyzed 193 IBD patients: 96 women and 97 men with average age 46.1 years. Ulcerative colitis 109 (56.6%) and 84 Crohn′s disease (43.5%). Oral mesalazine was used for IBD control in 48%, immunosuppressnat in 43.5% and targeted therapies, 28.5%. MPR detected non-adherence in 57 patients (29.5%). Patients with CD had a higher adherence than those with UC (78.6 vs 64.2% p=0.03). Non-adherence was higher in patients with mesalazine 41.3% (p=0.001) and lower with targeted therapies 15% (p=0.007). BMQ classified our IBD patients in 60% “ambivalent”, 36% “accepting”, 7% “indifferent” with no “sceptical”: Females had a higher puntuation in BMQ harm about medication scale (p= 0.006). Surgical patients scored higher about the necessity of their IBD medication (0.005) and patients with a low educational level showed many concerns about IBD medication (0.002). Nevertheless there were neither significant differences in BMQ general (abuse/harm) or specific (need/concern) scores nor in attitude profiles between patients with adequate adherence and non-adherent patients. Conclusion Non-adherence behaviour in IBD patients was not associated with beliefs about medication. Ulcerative colitis and oral mesalazine were related to lower adherence, meanwhile patients on directed therapies showed high adherence,

In 2018 year, the patent of original adalimumab expired and a new biosimilar version of adalimumab have been introduced on the Czech market. FKB-327 is one of the new biosimilar adalimumab versions and was approved for all indication of the original drug. This is the first experience with biosimilar adalimumab FKB-327 in IBD patients. Patients cohort comprised from 51 patients included 40 (82%) ones with Crohn´s disease and 9 (18%) ones with ulcerative colitis. Most of the patients (78%) have been naive for biologic therapy. A positive therapeutic effect during the median follow up time (37 weeks) was described in 47 (92%) patients. This drug was tolerated very well and none of the treated patients had to stop prematurely the drug administration due to significant side effects.

The incidence, prevalence, and cost of care associated with diagnosis and management of inflammatory bowel disease are on the rise. The role of gut microbiota in the causation of Crohn's disease and ulcerative colitis has not been established yet. Nevertheless, several animal models and human studies point towards the association. Targeting intestinal dysbiosis for remission induction, maintenance, and relapse prevention is an attractive treatment approach with minimal adverse effects. However, the data is still conflicting. The purpose of this article is to provide the most comprehensive and updated review on the utility of prebiotics and probiotics in the management of active Crohn’s disease and ulcerative colitis/pouchitis and their role in the remission induction, maintenance, and relapse prevention. A thorough literature review was performed on PubMed, Ovid Medline, and EMBASE using the terms “prebiotics AND ulcerative colitis”, “probiotics AND ulcerative colitis”, “prebiotics AND Crohn's disease”, “probiotics AND Crohn's disease”, “probiotics AND acute pouchitis”, “probiotics AND chronic pouchitis” and “prebiotics AND pouchitis”. Observational studies and clinical trials conducted on humans and published in the English language were included. A total of 71 clinical trials evaluating the utility of prebiotics and probiotics in the management of inflammatory bowel disease were reviewed and the findings were summarized. Most of these studies on probiotics evaluated lactobacillus, De Simone Formulation or Escherichia coli Nissle 1917 and there is some evidence supporting these agents for induction and maintenance of remission in ulcerative colitis and prevention of pouchitis relapse with minimal adverse effects. The efficacy of prebiotics such as fructooligosaccharides and Plantago ovata seeds in ulcerative colitis are inconclusive and the data regarding the utility of prebiotics in pouchitis is limited. The results of the clinical trials for remission induction and maintenance in active Crohn's disease or post-operative relapse with probiotics and prebiotics are inadequate and not very convincing. Prebiotics and probiotics are safe, effective and have great therapeutic potential. However, better designed clinical trials in the multicenter setting with a large sample and long duration of intervention are needed to identify the specific strain or combination of probiotics and prebiotics which will be more beneficial and effective in patients with inflammatory bowel disease.

Abstract Background Fatigue is a disabling symptom in patients with inflammatory bowel disease (IBD). Its prevalence, mechanism, and impact remain poorly understood. We determined changes in fatigue status over time and identified predictors of incident or resolving fatigue. Methods This was a prospective study nested within the IBD Partners cohort. Participants prospectively completed the Multidimensional Fatigue Inventory and the Functional Assessment of Chronic Illness Therapy-Fatigue at baseline, 6 months, and 12 months. A Functional Assessment of Chronic Illness Therapy-Fatigue score ≤43 defined significant fatigue. Multivariable regression models using baseline covariates were used to identify risk factors for incident fatigue at 6 months and to predict the resolution of fatigue. Results A total of 2429 patients (1605 with Crohn disease, 824 with ulcerative colitis) completed a baseline assessment, and 1057 completed a second assessment at 6 months. Persistent fatigue (at baseline and at 6 months) was the most common pattern, affecting two-thirds (65.8%) of patients. One-sixth (15.7%) of patients had fatigue at 1 timepoint, whereas fewer than one-fifth (18.5%) of patients never reported fatigue. Among patients not fatigued at baseline, 26% developed fatigue at 6 months. The strongest predictor of incident fatigue was sleep disturbance at baseline (odds ratio, 2.91; 95% confidence interval, 1.48–5.72). In contrast, only 12.3% of those with fatigue at baseline had symptom resolution by month 6. Resolution was more likely in patients with a diagnosis of ulcerative colitis, quiescent disease, and an absence of significant psychological comorbidity. Conclusions Fatigue is common in patients with IBD. However, only a few fatigued patients experience symptom resolution at 6 or 12 months, suggesting the need for novel interventions to ameliorate its impact.

AbstractIn the search for improved stool biomarkers for inflammatory bowel disease (IBD), an aptamer-based screen of 1129 stool proteins was conducted using stool samples from an IBD cohort. Here we report that of the 20 proteins subsequently validated by ELISA, stool Ferritin, Fibrinogen, Haptoglobin, Hemoglobin, Lipocalin-2, MMP-12, MMP-9, Myeloperoxidase, PGRP-S, Properdin, Resistin, Serpin A4, and TIMP-1 are significantly elevated in both ulcerative colitis (UC) and Crohn’s disease (CD) compared to controls. When tested in a longitudinal cohort of 50 UC patients at 4 time-points, fecal Fibrinogen, MMP-8, PGRP-S, and TIMP-2 show the strongest positive correlation with concurrent PUCAI and PGA scores and are superior to fecal calprotectin. Unlike fecal calprotectin, baseline stool Fibrinogen, MMP-12, PGRP-S, TIMP-1, and TIMP-2 can predict clinical remission at Week-4. Here we show that stool proteins identified using the comprehensive aptamer-based screen are superior to fecal calprotectin alone in disease monitoring and prediction in IBD.
