RESUMO
Background: The understanding of gender differences in inflammatory bowel disease (IBD) patients is an important step towards tailored treatment for the individual patient. The aim of this study was to compare disease phenotype, clinical manifestations, disease activity, and healthcare utilization between men and women with Crohn's disease (CD) and ulcerative colitis (UC). Methods: Two multicenter observational cohort studies with a prospective design were used to explore the differences between men and women regarding demographic and phenotypic characteristics and healthcare utilization. Detailed data on IBD-phenotype was mainly available from the Dutch IBD Biobank, while the COIN cohort provided healthcare utilization data. Results: In the Dutch IBD Biobank study, 2118 CD patients and 1269 UC patients were analyzed. Female CD patients were more often current smokers, and male UC patients were more often previous smokers. Early onset CD (<16 years) was more frequently encountered in males than in females (20% versus 12%, P < 0.01). Male CD patients were more often diagnosed with ileal disease (28% versus 20%, P < 0.01) and underwent more often small bowel and ileocecal resection. Extraintestinal manifestations (EIMs) were more often encountered in female IBD patients. In the COIN study, 1139 CD patients and 1213 UC patients were analyzed. Male CD patients used prednisone more often and suffered more often from osteopenia. IBD-specific healthcare costs did not differ between male and female IBD patients. Conclusions: Sex differences in patients with IBD include age of onset, disease location, and EIM prevalence. No large differences in therapeutic management of IBD were observed between men and women with IBD. 10.1093/ibd/izy004_video1izy004_Video_15786481854001.

BACKGROUND: Nonadherence to medical therapy is frequently encountered in patients with inflammatory bowel disease (IBD). We aimed to identify predictors for future (non)adherence in IBD. METHODS: We conducted a multicenter prospective cohort study with adult patients with Crohn's disease (CD) and ulcerative colitis (UC). Data were collected by means of 3-monthly questionnaires on the course of disease and healthcare utilization. Medication adherence was assessed using a visual analogue scale, ranging from 0% to 100%. Levels <80% were considered to indicate nonadherence. The Brief Illness Perception Questionnaire was used to identify illness perceptions. We used a logistic regression analysis to identify patient- and disease-related factors predictive of nonadherence 3 months after the assessment of predictors. RESULTS: In total, 1558 patients with CD and 1054 patients with UC were included and followed for 2.5 years. On average, 12.1% of patients with CD and 13.3% of patients with UC using IBD-specific medication were nonadherent. Nonadherence was most frequently observed in patients using mesalazine (CD), budesonide (UC) and rectally administrated therapy (both CD and UC). A higher perceived treatment control and understanding of the disease were associated with adherence to medical therapy. Independent predictors of future nonadherence were age at diagnosis (odds ratio [OR]: 0.99 per year), nonadherence (OR: 26.91), a current flare (OR: 1.30) and feelings of anxiety/depression (OR: 1.17), together with an area under the receiver-operating-characteristics curve of 0.74. CONCLUSIONS: Lower age at diagnosis, flares, feelings of anxiety or depression, and nonadherence are associated with future nonadherence in patients with IBD. Altering illness perceptions could be an approach to improve adherence behavior.

BACKGROUND: Capturing (non)-adherence to medical prescriptions in patients with inflammatory bowel disease (IBD) is challenging. We aimed to compare 3 different tools to measure self-assessed medication adherence of patients with IBD. METHODS: Adult patients with Crohn's disease and ulcerative colitis were prospectively followed. IBD-specific medication use was collected by 3-monthly questionnaires. At 2.5 years of follow-up, medication adherence was assessed using 3 tools: (1) the 8-item Morisky Medication Adherence Scale (MMAS-8), (2) the single question how well patients take their daily medication using a Visual Analogue Scale (VAS), and (3) the Forget Medicine scale (FM), assessing how often patients forget their medication. Cross-sectional agreement among measures was visualized with scatterplots and quantified with Spearman's rank correlations. RESULTS: In total, 913 patients with IBD were analyzed, 697 of whom received IBD-specific medication. High adherence on the MMAS-8 was consistent with high scores on the VAS and low scores on the FM. Disagreement between tools increased when patients were less adherent. A correlation of 0.44 was found between the MMAS-8 and VAS; -0.59 between the MMAS-8 and FM, and -0.55 between the VAS and FM (all P < 0.01). The VAS most optimally represented the quantitative variability of adherence, whereas the MMAS-8 and the FM might have resulted in overestimation or underestimation of adherence due to unequal differences in outcome possibilities. CONCLUSIONS: In patients with IBD, a VAS seems the most appropriate tool for quantifying medication adherence in clinical practice. The MMAS-8 may be used additionally to provide insight in specific reasons for non-adherence.

BACKGROUND: With the increasing use of anti-TNF therapy in inflammatory bowel disease (IBD), a shift of costs has been observed with medication costs replacing hospitalization and surgery as major cost driver. We aimed to explore the evolution of IBD-related costs over two years of follow-up. METHODS AND FINDINGS: In total 1,307 Crohn's disease (CD) patients and 915 ulcerative colitis (UC) patients were prospectively followed for two years by three-monthly web-based questionnaires. Changes of healthcare costs, productivity costs and out-of-pocket costs over time were assessed using mixed model analysis. Multivariable logistic regression analysis was used to identify costs drivers. In total 737 CD patients and 566 UC were included. Total costs were stable over two years of follow-up, with annual total costs of 7,835 in CD and 3,600 in UC. However, within healthcare costs, the proportion of anti-TNF therapy-related costs increased from 64% to 72% in CD (p<0.01) and from 31% to 39% in UC (p < 0.01). In contrast, the proportion of hospitalization costs decreased from 19% to 13% in CD (p<0.01), and 22% to 15% in UC (p < 0.01). Penetrating disease course predicted an increase of healthcare costs (adjusted odds ratio (adj. OR) 1.95 (95% CI 1.02-3.37) in CD and age <40 years in UC (adj. OR 4.72 (95% CI 1.61-13.86)). CONCLUSIONS: BD-related costs remained stable over two years. However, the proportion of anti-TNF-related healthcare costs increased, while hospitalization costs decreased. Factors associated with increased costs were penetrating disease course in CD and age <40 in UC.

BACKGROUND: Studies on the costs of health care in patients with inflammatory bowel disease (IBD) are increasingly conducted through the collection of self-reported data. We aimed to assess the concordance between estimated annual costs based on self-reported health care utilization and administrative data in IBD. METHODS: Consecutive patients with Crohn's disease or ulcerative colitis visiting the outpatient clinic were enrolled. Participants were asked to fill out a questionnaire on their IBD-specific health care utilization over the past year. Registered health care utilization over the same time period was extracted from medical records. Health care resources were multiplied by their unit prices to obtain costs. Cost estimates were compared, and correlation, sensitivity, and specificity were calculated. RESULTS: In total, 101 patients (70 Crohn's disease, 31 ulcerative colitis) were enrolled. Mean direct health care costs were &OV0556;4758 per year according to self-reported data and &OV0556;4866 according to administrative data (r = 0.97). Hospitalizations and diagnostics were relatively underreported with a sensitivity of 75% and 88%, and a specificity of 100% and 88%, respectively. One of 7 surgical procedures was overreported, and only 1 of 25 patients did not report the use of anti-tumor necrosis factor compounds. Suffering from a flare or having a pouch predicted a decreased recall with an adjusted odds ratio of 3.5 (95% confidence interval, 1.3-9.6) and 10.7 (95% confidence interval, 1.1-107.6), respectively. CONCLUSIONS: We report a high concordance between costs of self-reported health care utilization and administrative data over the past year in IBD. Self-reported health care utilization reliably measures the consumption of health care in IBD.

BACKGROUND AND AIMS: More data are warranted on the economic impact of different treatment strategies in ulcerative colitis (UC) patients. We compared the costs and quality of life of UC patients with a pouch reconstruction, an ileostomy or anti-tumour necrosis factor α (TNFα) therapy. METHODS: UC patients filled out 3-monthly questionnaires for 2 years. Differences in 3-monthly healthcare costs, productivity costs and patient costs were tested using mixed model analysis. Quality of life was assessed employing the ) and the inflammatory bowel disease questionnaire (IBDQ). RESULTS: Out of 915 UC patients, 81 (9%) had a pouch and 48 (5%) an ileostomy, and 34 (4%) were on anti-TNFα therapy. Anti-TNFα-treated patients reported high UC related-healthcare costs per 3 months (5350). Medication use accounted for 92% of healthcare costs. UC-attributable healthcare costs were 3-fold higher in ileostomy patients compared with pouch patients (1581 versus 407; p < 0.01). Main cost drivers in ileostomy patients were healthcare costs and ileostomy supplies (2 and 23% of healthcare costs, respectively). In pouch patients, the main cost driver was hospitalization, accounting for 50% of healthcare costs. Productivity loss did not differ between pouch and ileostomy patients (483 versus 377; p < 0.23), but was significantly higher in anti-TNFα-treated patients (1085). No difference was found in IBDQ scores, but pouch patients were found to have higher quality-adjusted life years than ileostomy patients and anti-TNFα-treated patients (0.90 [interquartile range 0.78-1.00] versus 0.84 [0.78-1.00] and 0.84 [0.69-1.00], respectively; p < 0.01). CONCLUSION: Patients receiving anti-TNFα therapy reported the highest healthcare cost, in which medication use was the major cost driver. Ileostomy patients were three times more expensive than pouch patients due to frequent hospitalization and ileostomy supplies.

BACKGROUND AND AIMS: Mucosal healing has become the treatment goal in patients with ulcerative colitis (UC) and Crohn's disease (CD). Whether low fecal calprotectin levels and histological healing combined with mucosal healing is associated with a further reduced risk of relapses is unknown. METHODS: Patients with CD, UC or inflammatory bowel disease-unclassified (IBD-U) scheduled for surveillance colonoscopy collected a stool sample prior to bowel cleansing. Only patients with mucosal healing (MAYO endoscopic score of 0) were included. Fecal calprotectin was measured using a quantitative enzyme-linked immunosorbent assay (R-Biopharm, Germany). Biopsies were obtained from four colonic segments, and histological disease severity was assessed using the Geboes scoring system. Patients were followed until the last outpatient clinic visit or the development of a relapse, which was defined as IBD-related hospitalization, surgery or step-up in IBD medication. RESULTS: Of the 164 patients undergoing surveillance colonoscopy, 92 patients were excluded due to active inflammation or missing biopsies. Of the remaining 72 patients (20 CD, 52 UC or IBD-U), six patients (8%) relapsed after a median follow-up of 11 months (range 5-15 months). Median fecal calprotectin levels at baseline were significantly higher for patients who relapsed compared with patients who maintained remission (284 mg/kg vs. 37 mg/kg. p < 0.01). Fecal calprotectin below 56 mg/kg was found to optimally predict absence of relapse during follow-up with 64% sensitivity, 100% specificity, 100% negative predictive value and 20% positive predictive value. The presence or absence of active inflammation determined by Geboes cut-off score of 3.1 was less strongly associated with the risk of relapse (64% sensitivity, 33% specificity, 9% negative predictive value and 92% positive predictive value. CONCLUSION: Low calprotectin levels identify IBD patients who remain in stable remission during follow-up.
