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 & Aims: Oral mesalamine (5-aminosalicylate) is the current standard of care for mild-to-moderate ulcerative colitis. We investigated the efficacy and safety of once daily administration of prolonged-release mesalamine granules in maintenance of remission in patients with quiescent ulcerative colitis, compared with the well established twice daily dosing regimen., Methods: In this multicenter, randomized, single blind, noninferiority trial, 362 patients with quiescent ulcerative colitis were randomly assigned (1:1) to groups that were given oral mesalamine 2 g, once daily, or 1 g, twice daily, for 12 months. The primary objective was to compare remission rates at 1 year, based on the ulcerative colitis disease activity index score, using Kaplan-Meier methodology., Results: At 1 year, 70.9% of the group given 2 g mesalamine once daily remained in remission vs 58.9% of the group given 1 g mesalamine twice daily; this difference was statistically significant (P = .024), indicating the increased efficacy of once daily, compared with twice daily, dosing. Self-reported adherence to therapy, measured by visual analog scale score after 4, 8, and 12 months, was significantly greater in the group given 2 g mesalamine once daily, compared with twice daily, at all but 1 study visit (P < .05). Compliance measured by medication taken was not significantly different between the groups. The difference between the 2 groups in overall incidence of adverse events was not statistically significant (P = .23)., Conclusions: Patients with ulcerative colitis given prolonged-release oral mesalamine 2 g once daily had better remission rates, acceptability, and self-reported adherence to therapy compared with patients given oral mesalamine 1 g twice daily.

Background: The mechanisms for the observed low prevalence of Helicobacter pylori infection in inflammatory bowel disease (IBD) are unknown, but might be important for the pathogenesis of IBD. We have studied the seroprevalence of H. pylori in different categories of IBD and evaluated the role of medical therapy, smoking and social status. We also analysed the effect of seropositivity on the age of onset of IBD in order to find possible evidence for the protective effect of the infection., Methods: We studied 296 (mean age 43 years, range 18-79; women 144) unselected patients with IBD, including 185 with ulcerative colitis (UC). 94 with Crohn disease (CD), and 17 with indeterminate colitis (IC). Seventy healthy age- and sex-matched subjects served as controls. Serum samples were studied for H. pylori antibodies. Detailed clinical history was obtained from patient records and by face-to-face interview., Results: The prevalence of H. pylori infection was lower in IBD patients (24%) than in controls (37%; P = 0.029), and in CD lower (13%) than in UC (30%; P = 0.002). Seropositivity was not related to sulphasalazine treatment or smoking. Age of onset of IBD was higher in seropositive (mean 40 years) than in seronegative patients (30 years: P < 0.001). The age of onset of IBD showed unimodal distribution in H. pylori seronegative patients, with a peak between 30 and 40 years, although there was some evidence of bimodality in CD. In contrast, H. pylori seropositive patients had clear bimodal pattern with peaks at 20-40 and 50-60 years of age., Conclusions: Our results confirm the low prevalence of H. pylori infection in IBD, and in particular in CD. The significantly higher age of onset and bimodal pattern of age-specific incidence in seropositive IBD patients suggest that H. pylori infection significantly modifies the development of IBD and may have a protective effect.

Background: Some patients with inflammatory bowel disease have reduced bone mineral density, but the risk factors for osteoporosis in these patients are unclear., Methods: To evaluate the effect of smoking and other lifestyle factors on bone mineral density in patients with inflammatory bowel disease, we studied 67 patients with ulcerative colitis, 78 with Crohn's disease, 7 with indeterminate colitis, and 73 healthy control subjects. Bone mineral density of the lumbar spine and the proximal femur was measured, using dual-energy X-ray absorptiometry. Measures of smoking and other lifestyle factors were assessed in an interview., Results: The female ex- or current smokers with inflammatory bowel disease (n = 38) had lower age- and sex-adjusted Z-scores of bone mineral density than the female patients who had never smoked (n = 34) (Z-scores in the lumbar spine, -0.277 (1.283) (mean (standard deviation)) and 0.487 (1.056), respectively; p = 0.008; and in the femoral neck, -0.626 (1.055) and -0.013 (1.019); p = 0.015). These differences were not explained by the type or treatment of the disease, the menstrual history, or the use of estrogen preparations. In male patients no differences in bone mineral density were found between ex- or current smokers and non-smokers. Coffee drinking and alcohol consumption were not associated with bone mineral density in these patients., Conclusions: Smoking is associated with low bone mineral density in women with inflammatory bowel disease. This association is not related to the body mass index, the medical treatment, or the type of disease.

To assess the prevalence of and risk factors for low bone mineral density in inflammatory bowel disease (IBD), 152 IBD patients and 73 healthy controls were studied. Sixty seven patients had ulcerative colitis, 78 had Crohn's disease (52 of them (66.7%) had ileal disease), and seven had indeterminate colitis. Bone mineral density values (g/cm2) measured by dual energy x ray absorbtiometry at the spine (L2-L4), the femoral neck, Ward's triangle, and the trochanter were 1.177, 0.948, 0.850, and 0.838 in the patients and 1.228 (p = 0.034), 1.001 (p = 0.009), 0.889 (NS), and 0.888 (p = 0.012) in the control group, respectively. The type or extent of the disease or previous small bowel resection did not have any significant effect on the bone mineral density values. There was a weak, but statistically significant negative correlation between bone mineral density and the total lifetime corticosteroid dose (in the lumbar spine r = -0.164, p = 0.04, the femoral neck r = -0.185, p = 0.02, Ward's triangle r = -0.167, p = 0.04, and the trochanter r = -0.237, p = 0.003). The patients whose lifetime corticosteroid dose (prednisone/prednisolone) was more than 10 g had especially low bone mineral density (p < 0.05 compared with the groups with no or less than 5 g of corticosteroid). The patients who had never taken peroral corticosteroids did not have decreased bone mineral density. In conclusion, IBD patients have significantly lower bone mineral density values than healthy controls, but the difference is not so great as has been reported previously. Low bone mineral density values in these patients are related to high lifetime corticosteroid doses.
