Limited data is available on vedolizumab combination therapies in real-world clinical practice. Here, we evaluated the concomitant corticosteroid, immunosuppressive, and 5-aminosalicylic acid utilization of inflammatory bowel disease (IBD) patients treated with vedolizumab in a nationwide, retrospective, non-interventional, multi-centre chart review study. All adult patients from 27 Finnish gastroenterology centres with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) who had at least one vedolizumab infusion since it's availability in Finland were included in the study. Data were collected from medical charts at baseline (vedolizumab treatment initiation), week 14, and month 6. The majority of patients who used corticosteroids at the baseline and persisted on vedolizumab treatment for 6 months were taken off corticosteroid treatment by the 6-month time point (CD, 54.5%; UC, 69.8%). Modest corticosteroid dose reductions were observed among treatment persistent CD patients from the baseline until month 6. Corticosteroid users had less vedolizumab discontinuations due to primary ineffectiveness and more discontinuations due to adverse events than patients not using corticosteroids. Vedolizumab may have a corticosteroid sparing effect in real-world clinical practice. Concomitant corticosteroid use may lead to a lower rate of vedolizumab discontinuation due to primary ineffectiveness, but a higher discontinuation rate due to adverse events., (Copyright © 2019.

Objectives: The efficacy and tolerability of vedolizumab in the treatment of inflammatory bowel diseases (IBD) has been demonstrated in an extensive GEMINI clinical trial programme. Clinical trials represent highly selected patient populations and, therefore, it is important to demonstrate effectiveness in real-life clinical practice. We set out to assess real-world treatment outcomes of vedolizumab in a nationwide cohort of treatment refractory Finnish Crohn's disease (CD) and ulcerative colitis (UC) patients., Methods: This was a nationwide, retrospective, non-interventional, multi-centre chart review study. All adult patients from 27 Finnish gastroenterology centers with a diagnosis of UC or CD who had at least one vedolizumab infusion since the availability of the product in Finland, were included in the study. Data were collected retrospectively from medical charts at baseline, week 14, and month 6. The primary outcome measure was treatment persistence 24 weeks post-vedolizumab initiation., Results: A total of 247 patients were included (108 CD, 139 UC). A total of 75.0% (n = 81) of all CD patients and 66.2% (n = 92) of all UC patients, were persistent on vedolizumab therapy for 6 months post treatment initiation. At month 6, 41.8% (28/67) of the treatment persistent CD patients and 73.3% (63/86) of the treatment persistent UC patients achieved clinical remission. Significant improvement in endoscopic scores were observed among treatment persistent patients (CD, n = 17, ΔSES-CD=-5.5, p = .008; UC, n = 26, ΔMayo endoscopic score =-0.5, p = .003) at month 6., Conclusions: Vedolizumab provides an effective and well-tolerated treatment option in real-world clinical practice even among treatment refractory IBD patients.

Background: Few data are available on the disease course in patients with inflammatory bowel disease (IBD) in deep remission after discontinuing tumor necrosis factor α (TNFα)-blocking therapy. In this prospective multicenter study, we evaluated the relapse rate, predictive factors, and the response to retreatment after discontinuation of TNFα-blocking therapy in patients with IBD in deep remission., Methods: We recruited 52 patients (17 Crohn's disease, 30 ulcerative colitis, and 5 IBD unclassified) in clinical, endoscopic, and fecal calprotectin-based (<100 μg/g) remission after at least 1 year of TNFα-blocking therapy. Clinical and endoscopic remission and relapse were defined according to validated indices. After discontinuation of therapy, the patients were followed up with endoscopic assessment at 4 and 12 months. In the event of a clinical relapse with endoscopically active disease or minor clinical symptoms but severe endoscopic relapse, TNFα-blocking therapy was restarted., Results: After a median follow-up time of 13 (range, 12-15) months, 17/51 (33%) patients relapsed (5/17 Crohn's disease, 12/34 ulcerative colitis/IBD unclassified, 1 patient lost to follow-up at 6 mo). Ten experienced clinical and endoscopic relapse, 5 clinical relapse with mild endoscopic activity, and 2 severe endoscopic relapse. No specific predictive factors were associated with the relapse. Retreatment was effective in 94% of patients., Conclusions: After cessation of TNFα-blocking therapy in patients with IBD in deep remission, up to 67% remained in clinical remission during the 12-month follow-up. Importantly, 85% of these patients sustained endoscopic remission. The response to restart of TNFα antagonists was effective and well tolerated.

Background and Aims: Deep remission, meaning clinical remission with mucosal healing (MH), with anti-tumor necrosis factor-alpha (TNF-α) agents is a new target for therapy in inflammatory bowel disease (IBD). Our aim was to study how often patients on TNF-α blocking therapy actually achieve deep remission., Methods: The total of 252 IBD patients retrospectively included (183 Crohn's disease (CD), 62 ulcerative colitis (CU) or 7 inflammatory bowel disease unclassified-type colitis (IBDU)) received TNFα-antagonists (177 infliximab, 75 adalimumab) for at least 11 months and underwent ileocolonoscopy. We reviewed endoscopic and histological findings, clinical symptoms, C-reactive protein (CRP), and fecal calprotectin (FC) levels, and data on TNF-α blocking therapy. Defining deep remission as no clinical symptoms with endoscopic remission (the simple endoscopic score for Crohn's disease, SES-CD 0-2 or Mayo endoscopic subscore 0-1)., Results: Of the 252 patients, 168 (67%) were in clinical remission and 122 (48%) in deep remission after a median of 23 months of maintenance therapy. Of the 183 CD patients, 117 (64%) reached clinical remission and 79 (43%) deep remission. Of the UC patients, 52 (75%) were in clinical remission and 43 (62%) in deep remission. The majority of patients in deep remission (n=99, 81%) also had histologically inactive disease. Both median CRP and FC levels were significantly lower in patients with deep remission., Conclusion: Reassuringly, half of the IBD patients on the TNFα-blocking maintenance therapy achieved deep remission. The majority of patients in deep remission also achieved histological remission., (Copyright © 2012 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.)

Objective: Data on fecal calprotectin and S100A12 in predicting wireless capsule endoscopy (WCE) findings in suspicion of Crohn's disease (CD) are scarce. Our aim was to study the role of calprotectin and S100A12 in predicting inflammatory lesions of small bowel in patients undergoing WCE., Material and Methods: 84 patients undergoing WCE (77 for suspicion of CD and 7 CD patients for evaluation of disease extent) were prospectively recruited. WCE findings were scored. Patients provided a stool sample for measurements of biomarkers. Patients underwent an esophagogastroduodenoscopy and ileocolonoscopy before WCE., Results: WCE was abnormal in 35 (42%) of 84 patients: 14 patients with CD, 8 with NSAID enteropathies, 8 with angioectasias, 4 with polyps or tumors, and 1 with ischemic stricture. Median calprotectin concentration in the study population was 22 μg/g (range 2-342) and S100A12 concentration 0.048 μg/g (range 0.003-1.215). Fecal calprotectin was significantly higher in CD patients (median 91, range 2-312) compared with those with normal WCE or other abnormalities (p = 0.008), whereas fecal S100A12 (0.087 μg/g, range 0.008-0.896) did not differ between the groups (p = 0.166). In detecting inflammatory small bowel lesions, sensitivity, specificity, positive predictive value, and negative predictive value for fecal calprotectin (cutoff 50 μg/g) were 59%, 71%, 42%, and 83%, and for S100A12 (cutoff 0.06 μg/g) these were 59%, 66%, 38%, and 82%., Conclusions: In predicting small bowel inflammatory changes, fecal biomarkers calprotectin and S100A12 have moderate specificity, but low sensitivity. Neither fecal calprotectin nor S100A12 can be used for screening or excluding small bowel CD.
