Inflammatory bowel disease (IBD) is increasingly diagnosed among elderly persons (older than 60 years). Epidemiological studies show that late-onset IBD is characterized by predominance of colonic disease, milder disease course, and less frequent occurrence of extraintestinal manifestations. However, due to comorbidities, polypharmacy and reduced resistance to severe disease course elderly patients have an increased risk of mortality. Drug treatment generally follows the same algorithms as in the younger IBD patients. This is challenging for the treating physician as this population is usually underrepresented in clinical trials and treatment outcomes as well as safety data on the elderly population are scarce. Choice of drugs should consider risk of infections, skin cancer, lymphoma, and metabolic as well as cardiovascular side effects. Considering comorbidities, surgical interventions such as colectomy with ileo-anal pouch anastomosis for refractory ulcerative colitis can be performed safely provided that the anal sphincter function is adequately maintained. Special attention should be given in this age group to general health issues, including nutrition, vaccination, bone, muscle, and mental health as well as colorectal and skin cancer screening.

Background: Loss of response is frequently encountered in patients with inflammatory bowel disease (IBD) treated with antitumor necrosis factor (TNF) agents. Therapeutic drug monitoring (TDM) and antidrug antibody measurement are increasingly used in this setting. Methods: To establish a consensus on the use of TDM in the context of loss of response to anti-TNFs, we performed a vote using a Delphi-style process followed by an expert panel discussion among 8 IBD specialists practicing in Switzerland, Europe. Statements were rated on an even Likert-scale ranging from 1 (strong disagreement) to 4 (strong agreement), based on expert opinion and the available literature. Results: The experts agreed on the following statements: (i) loss of response is associated with inadequate drug levels in both Crohn's disease and ulcerative colitis; (ii) best timepoint for measuring drug levels is prior to the next application (= trough levels) with different thresholds for anti-TNF agents (infliximab 5 μg/mL, adalimumab 8 μg/mL, certolizumab pegol 10 μg/mL); (iii) antidrug antibodies are predictive for loss of response; and (iv) antidrug-antibody titers and drug trough levels are key determinants in the treatment algorithm. Data about non-anti-TNF biologics were considered too limited to propose recommendations. Conclusion: A Delphi-style consensus among 8 IBD experts shows that TDM and measurement of antidrug-antibody titers are useful in the context of loss of response to anti-TNF. Optimal cutoff levels depend on the type of anti-TNF. These values are critical in the decision making process. More studies are needed to address the value of such measurements for non-anti-TNF biologics. [ABSTRACT FROM AUTHOR]

Background and aims. Limited data from large cohorts are available on tumor necrosis factor (TNF) antagonists (infliximab, adalimumab, certolizumab pegol) switch over time. We aimed to evaluate the prevalence of switching from one TNF antagonist to another and to identify associated risk factors. Methods. Data from the Swiss Inflammatory Bowel Diseases Cohort Study (SIBDCS) were analyzed. Results. Of 1731 patients included into the SIBDCS (956 with Crohn's disease [CD] and 775 with ulcerative colitis [UC]), 347 CD patients (36.3%) and 129 UC patients (16.6%) were treated with at least one TNF antagonist. A total of 53/347 (15.3%) CD patients (median disease duration 9 years) and 20/129 (15.5%) of UC patients (median disease duration 7 years) needed to switch to a second and/or a third TNF antagonist, respectively. Median treatment duration was longest for the first TNF antagonist used (CD 25 months; UC 14 months), followed by the second (CD 13 months; UC 4 months) and third TNF antagonist (CD 11 months; UC 15 months). Primary nonresponse, loss of response and side effects were the major reasons to stop and/or switch TNF antagonist therapy. A low body mass index, a short diagnostic delay and extraintestinal manifestations at inclusion were identified as risk factors for a switch of the first used TNF antagonist within 24 months of its use in CD patients. Conclusion. Switching of the TNF antagonist over time is a common issue. The median treatment duration with a specific TNF antagonist is diminishing with an increasing number of TNF antagonists being used. [ABSTRACT FROM AUTHOR]

Background and Aims: Although systemic corticosteroids are successfully administered for the induction of clinical response and remission in the majority of patients with inflammatory bowel disease (IBD) presenting with a flare, a proportion of these patients demonstrate a primary nonresponse to steroids or in the case of an initial response, they develop a resistance or a steroid dependence. Long-term therapy with corticosteroids for treatment of IBD should be avoided, given the high frequency of adverse treatment effects. Knowledge about treatment strategies in case of steroid nonresponse is therefore highly relevant. Methods: A systematic literature research was performed using Medline and Embase to summarize the currently recommended treatment strategies for steroid-resistant IBD. Results: Treatment of steroid-resistant Crohn's disease is based on the introduction of immunomodulators such as azathioprine, 6-mercaptopurine or methotrexate, the anti-TNF drugs infliximab, adalimumab and certolizumab pegol. In the case of steroid resistance in ulcerative colitis, aminosalicylates, the above-mentioned irnmunomodulators, infliximab, adalimumab or calcineurin inhibitors such as ciclosporin or tacrolimus may be administered. Conclusion: This review summarizes the current evidence for treating steroid-resistant IBD. [ABSTRACT FROM AUTHOR]

Abstract: Background and aims: The clinical course of Crohn''s disease (CD) is highly variable with a subgroup of patients developing a progressive disease course necessitating immunosuppressive therapy (IT). However, reliable, stable and non-invasive individual clinical parameters in order to identify patients at risk for undergoing subsequent IT have not been sufficiently established. We therefore aimed to identify such clinical parameters. Methods: A retrospective, multicenter analysis of CD patients from 6 German tertiary IBD centers was performed. Patients were classified into two groups depending on requiring IT or not. Personal data, clinical and laboratory parameters during the first 3months after CD diagnosis and effects of initial medical therapy were compared between these two groups. Results: In 218 (61.8%) of the 353 patients the CD course necessitated IT. Those patients were significantly younger at symptom onset and diagnosis, and required significantly more often a systemic corticosteroid therapy. Furthermore, significant differences in serological markers of inflammation were observed. Age, gender and the effect of initial steroid therapy were used to develop a prognostic model predicting the individual probability of necessitating IT. Conclusions: The simple clinical items age at diagnosis, gender, and need for systemic steroid therapy can predict a progressive disease course in early CD. Our model based on these parameters allows an individualized estimation of each patient''s risk to develop a progressive disease course. Thereby, our model can help in deciding if patients will need immunosuppressive drugs early in the disease course or if a careful watch and wait strategy is justified. [Copyright &y& Elsevier]

OBJECTIVES:Data on the frequency of extraintestinal manifestations (EIMs) in Crohn's disease (CD) and ulcerative colitis (UC) and analyses of their risk factors are scarce. We evaluated their prevalence and risk factors in a large nationwide cohort of inflammatory bowel disease (IBD) patients.METHODS:IBD patients from an adult clinical cohort in Switzerland (Swiss IBD cohort study) were prospectively included. Data from validated physician enrolment questionnaires were analyzed.RESULTS:A total of 950 patients were included, 580 (61%) with CD (mean age 41 years) and 370 (39%) with UC (mean age 42 years). Of these, 249 (43%) of CD and 113 (31%) of UC patients had one to five EIMs. The following EIMs were found: arthritis (CD 33%, UC 21%), aphthous stomatitis (CD 10%, UC 4%), uveitis (CD 6%, UC 4%), erythema nodosum (CD 6%, UC 3%), ankylosing spondylitis (CD 6%, UC 2%), psoriasis (CD 2%, UC 1%), pyoderma gangrenosum (CD and UC each 2%), and primary sclerosing cholangitis (CD 1%, UC 4%). Multiple logistic regression identified the following risk factors for ongoing EIM in CD: active disease (odds ratio (OR)=1.95, 95% confidence interval (CI)=1.17-3.23, P=0.01), and positive IBD family history (OR=1.77, 95% CI=1.07-2.92, P=0.025). No risk factors were identified in UC patients.CONCLUSIONS:EIMs are a frequent problem in CD and UC patients. Active disease and positive IBD family history are associated with ongoing EIM in CD patients. Identification of EIM prevalence and associated risk factors may result in increased awareness for this problem and thereby facilitating their diagnosis and therapeutic management.

Abstract: Background: Anaemia represents a common complication of inflammatory bowel disease (IBD). Most studies on anaemia in IBD patients have been performed in tertiary referral centres (RC) and data from gastroenterologic practices (GP) are lacking. We investigated the frequency and severity of anaemia in IBD patients from tertiary referral centres and gastroenterologic practices compared to the general population. Methods: Data were acquired from patients included in the Swiss IBD Cohort Study. IBD activity was evaluated by CDAI and modified Truelove and Witts severity index (MTWSI). Anaemia was defined as haemoglobin ≤120g/L in women and ≤130g/L in men. Results: 125 patients from RC (66 with Crohn''s disease (CD) and 59 with ulcerative colitis (UC)) and 116 patients from GP (71 CD and 45 UC) were included and compared to 6074 blood donors. Anaemia was found in 21.2% (51/241) of the IBD patients and more frequently in patients from RC as compared to GP and healthy controls (28.8% vs. 12.9% vs. 3.4%; P <0.01). IBD patients from RC suffered more frequently from active disease compared to IBD patients in GP (36% vs. 23%, P =0.032). Supplementation therapy (iron, vitamine B12, folic acid) was performed in 40% of anaemic IBD patients in GP as compared to 43% in RC. Conclusions: Anaemia is a common complication in patients with IBD and significantly more prevalent in patients from referral centres as compared to patients from gastroenterologic practices. Physicians treating IBD patients should pay attention to the presence of anaemia and ensure sufficient supplementation therapy. [Copyright &y& Elsevier]

Background: Enquiries among patients on the one hand and experimental and observational studies on the other suggest an influence of stress on inflammatory bowel diseases (IBD). However, since this influence remains hypothetical, further research is essential. We aimed to devise recommendations for future investigations in IBD by means of scrutinizing previously applied methodology. Methods: We critically reviewed prospective clinical studies on the effect of psychological stress on IBD. Eligible studies were searched by means of the PubMed electronic library and through checking the bibliographies of located sources. Results: We identified 20 publications resulting from 18 different studies. Sample sizes ranged between 10 and 155 participants. Study designs in terms of patient assessment, control variables, and applied psychometric instruments varied substantially across studies. Methodological strengths and weaknesses were irregularly dispersed. Thirteen studies reported significant relationships between stress and adverse outcomes. Conclusions: Study designs, including accuracy of outcome assessment and repeated sampling of outcomes (i.e. symptoms, clinical, and endoscopic), depended upon conditions like sample size, participants’ compliance, and available resources. Meeting additional criteria of sound methodology, like taking into account covariates of the disease and its course, is strongly recommended to possibly improve study designs in future IBD research.
