Neutrophil-to-Lymphocyte Ratio for Predicting Loss of Response to Infliximab in Ulcerative Colitis. PLoS One 2017; 12:e0169845. [PMID: 28076386 PMCID: PMC5226844 DOI: 10.1371/journal.pone.0169845] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 12/25/2016] [Indexed: 12/18/2022] Open
Abstract
Objectives Neutrophil-to-lymphocyte ratio (NLR) has been used to determine the outcome in malignancies and coronary heart disease. Some reports considered the value of NLR as a predictor of response to infliximab in patients with Crohn’s disease or rheumatoid arthritis; however, no similar studies have been reported for ulcerative colitis (UC). This study aimed to evaluate the clinical significance of the baseline NLR in patients with UC treated by infliximab. Materials and Methods Patients with moderate-to-severe active UC who received the first infliximab infusion in our hospital between 2010 and 2015, who showed clinical response during the induction period, were retrospectively evaluated for long-term outcomes and risk factors for loss of response (LOR) during infliximab maintenance therapy. Baseline inflammatory markers including NLR were measured within one week before the initiation of infliximab. Results Fifty-nine patients with moderate-to-severe active UC started treatment with infliximab and 37 patients (62.7%) experienced clinical response after induction therapy. Fourteen of 37 patients on maintenance therapy lost the response during follow-up. Baseline NLR of patients with LOR was significantly higher than in patients with sustained response. The NLR cut-off value of 4.488 was predictive of LOR, using receiver operating characteristic analysis (sensitivity: 78.6%, specificity: 78.3%). A univariate analysis revealed a significant relationship between relapse-free survival and the NLR (P = 0.018). Multivariate analysis indicated the NLR as an independent prognostic factor for LOR (hazard ratio = 3.86, 95% confidence interval: 1.20–12.4, P = 0.023). Conclusions Baseline NLR is a useful prognostic marker in patients with moderate-to-severe active UC treated with infliximab, and may contribute to appropriate use of infliximab.

Systematic review with meta-analysis: comparative efficacy of immunosuppressants and biologics for reducing hospitalisation and surgery in Crohn's disease and ulcerative colitis. Aliment Pharmacol Ther 2017; 45:3-13. [PMID: 27862107 DOI: 10.1111/apt.13847] [Citation(s) in RCA: 169] [Impact Index Per Article: 24.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2016] [Revised: 08/26/2016] [Accepted: 10/09/2016] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Crohn's disease (CD) and ulcerative colitis (UC) have a progressive course leading to hospitalisation and surgery. The ability of existing therapies to alter disease course is not clearly defined. AIM To investigate the comparative efficacy of currently available inflammatory bowel disease (IBD) therapies to reduce hospitalisation and surgery. METHODS We conducted a systematic review in MEDLINE/PubMed for randomised controlled trials (RCT) published between January 1980 and May 2016 examining efficacy of biological or immunomodulator therapy in IBD. We performed direct comparisons of pooled proportions of hospitalisation and surgery. Pair-wise comparisons using a random-effects Bayesian network meta-analysis were performed to assess comparative efficacy of different treatments. RESULTS We identified seven randomised controlled trials (5 CD; 2 UC) comparing three biologics and one immunomodulator with placebo. In CD, anti-TNF biologics significantly reduced hospitalisation [Odds ratio (OR) 0.46, 95% confidence interval (CI) 0.36-0.60] and surgery (OR 0.23, 95% CI 0.13-0.42) compared to placebo. No statistically significant reduction was noted with azathioprine or vedolizumab. Azathioprine was inferior to both infliximab and adalimumab in preventing CD-related hospitalisation (>97.5% probability). Anti-TNF biologics significantly reduced hospitalisation (OR 0.48, 95% CI 0.29-0.80) and surgery (OR 0.67, 95% CI 0.46-0.97) in UC. There were no statistically significant differences in the pair-wise comparisons between active treatments. CONCLUSIONS In CD and UC, anti-TNF biologics are efficacious in reducing the odds of hospitalisation by half and surgery by 33-77%. Azathioprine and vedolizumab were not associated with a similar improvement, but robust conclusions may be limited due to paucity of RCTs.

Abstract
BACKGROUND Treatment of active ulcerative colitis is associated with incomplete efficacy, adverse events, and loss of response. Toll-like receptor-9 mediates innate and adaptive immune response toward intestinal microorganisms. The oral synthetic oligonucleotide toll-like receptor-9 modulator has demonstrated anti-inflammatory properties in colitis murine models and a satisfactory safety profile in humans. AIM To evaluate the efficacy and safety of BL-7040 (a Toll-like receptor-9 modulator) in patients with moderately active ulcerative colitis. METHODS Moderately active ulcerative colitis patients were included in this multicenter, open-label phase IIa trial. Concomitant mesalamine and steroids at a stable dose were allowed. Clinical outcome was evaluated using the Mayo score, histology, and mucosal cytokine levels. Side effects were registered. RESULTS Sixteen out of 22 patients completed a 5-week treatment course and 2-week follow-up. Six patients discontinued the study, three of them due to adverse events. Clinical remission was observed in two patients (12.5 %), and clinical response as well as mucosal healing were achieved in half (50 %) of the patients, while all others remained stable. Furthermore, mucosal neutrophil (p = 0.002) and mucosal interleukin-6 levels (p = 0.046) were significantly reduced in responders compared to non-responders. Toll-like receptor-9 was well tolerated with only one unrelated to study drug serious adverse event (hemoglobin decrease) and 29 mild-to-moderate adverse events. CONCLUSIONS Oral administration of the Toll-like receptor-9 agonist BL-7040 appeared efficacious, safe and well tolerated in patients with moderately active ulcerative colitis.

Abstract
Background Biological therapies are increasingly used to treat ulcerative colitis (UC). Aim To compare the efficacy of biologics in adults with moderately-to-severely active UC, stratified by prior exposure to anti-tumour necrosis factor (anti-TNF) therapy. Methods A systematic literature review was undertaken to identify studies of biologics approved for UC. Network meta-analysis was conducted for endpoints at induction and maintenance. Results Seven studies were included in the meta-analysis of induction treatment for anti-TNF therapy-naïve patients. All biologics were more effective than placebo in inducing clinical response, clinical remission, and mucosal healing. Infliximab demonstrated a statistically significant improvement over adalimumab in clinical response (odds ratio [OR] [95% credible interval (CrI)]: 2.19 [1.35–3.55]), clinical remission (OR [95% CrI]: 2.81 [1.49–5.49]), and mucosal healing (OR [95% CrI]: 2.23 [1.21–4.14]); there were no other significant differences between biologics for induction efficacy. Five studies were included in the meta-analysis of maintenance treatment, two studies rerandomised responder patients at end of induction, and three followed the same patients ‘straight through’. To account for design differences, the number of responders at end of induction was assumed to be equivalent to the number rerandomised. Vedolizumab showed significantly different durable clinical response from comparators (OR [95% CrI] infliximab 3.18 [1.14–9.20], golimumab 2.33 [1.04–5.41], and adalimumab 3.96 [1.67–9.84]). In anti-TNF therapy-experienced patients, only vedolizumab and adalimumab could be compared. At induction, no significant differences in efficacy were seen. During maintenance, vedolizumab showed significantly improved rates of mucosal healing versus adalimumab (OR [95% CrI]: 6.72 [1.36–41.0]). Conclusions This study expands the understanding of comparative efficacies of biologic treatments for UC, encompassing outcomes and populations not previously studied. All biologic treatments were effective for UC during induction. Vedolizumab demonstrated possible clinical benefits in the maintenance setting versus all comparators, irrespective of prior anti-TNF exposure and after adjusting for differences in study design.

Abstract
Inflammatory bowel disease (IBD) comprises two distinct conditions: ulcerative colitis and Crohn’s disease, both of which are chronic, relapsing disorders carrying significant morbidity, mortality and healthcare costs. With growing attention to coordinated healthcare for patients with chronic systemic diseases, this review focuses on the care of IBD patients in remission, their concerns, quality of life, follow-up, the role of primary care physicians and the IBD-specific aspects of long-term care. We did an extensive PubMed search for articles pertaining to IBD patients in remission and, along with the authors’ experience, formulated a comprehensive review. The difficulties faced by IBD patients in remission include but are not limited to education and employment concerns, psychosocial issues, problems related to health insurance, nutrition, fertility and infections. This review also addresses newer treatment modalities, the debatable effects of smoking on IBD and the importance of vaccination. IBD in remission can be a challenge due to its multifaceted nature; however, with a coordinated approach by gastroenterologists and other involved practitioners, several of these issues can be addressed.

Abstract
On February 9, 2016, the Food and Drug Administration Arthritis Advisory Committee recommended by a vote of 21 to 3, that the biosimilar to infliximab, CT-P13, be approved for rheumatoid arthritis and ankylosing spondylitis and, by extrapolation, for all the indications for which infliximab is currently approved, including adult and pediatric ulcerative colitis and Crohn's disease. On April 5, 2016, the Food and Drug Administration concurred with this recommendation and approved CT-P13 (Inflectra; Pfizer Inc.) for all diseases for which infliximab had previously been approved, including adult and pediatric moderate to severe ulcerative colitis and pediatric and adult moderate to severe and fistulizing Crohn's disease. This was despite the absence of any randomized controlled trials studying the infliximab biosimilar in any inflammatory bowel disease. This highly controversial approach has been criticized by various rheumatology and gastroenterology professional societies around the world. This review will cover the stepwise approach to biosimilar development, issues of extrapolation and interchangeability, and conclude with a discussion of the regulatory, intellectual property issues, and financial implications, which will all intersect in the decision and ability to prescribe a biosimilar or reference anti-tumor necrosis factor drug.

Abstract
Objectives: Inflammatory bowel disease (IBD) is a heterogeneous group of chronic inflammatory gastrointestinal conditions with variable disease courses often requiring significant healthcare expenditures. We aimed to identify disease trajectory patterns based on longitudinal financial expenditures and to assess the association of classic disease activity parameters with financial charges. Methods: This was an analysis of a consented, prospective, natural history IBD registry (2009–2013) from a tertiary IBD center of 2,203 patients and their associated medical charges excluding pharmacy expenses. We applied group-based trajectory modeling to longitudinal healthcare financial charges to determine patterns of charges. We assessed the association between charge patterns and disease activity, quality of life, healthcare utilization, and medication requirement. Results: The final model included 1,600 IBD patients with 5-year charges. We identified six distinct trajectories over the study period. Consistently High charges were associated with Crohn’s disease (66.0% Consistently High patients, P<0.01), perianal involvement (22.6%, P<0.01), ulcerative colitis extent (89.7% extensive, P=0.01), prior IBD surgery (52.5%, P<0.01), and depression/anxiety (36.2%, P<0.01). Compared with other trajectories, Consistently High charges had higher 5-year disease activity indices (Harvey–Bradshaw P<0.01; ulcerative colitis activity index P<0.01), elevated C-reactive protein rates (72.3%, P<0.01), IBD surgery (64.5%, P<0.01), hospitalization (97.2%, P<0.01), corticosteroid (70.9%, P<0.01) and antitumor necrosis factor requirement (50.4%, P<0.01), and worse quality of life (P<0.01). Annual trends in parameters were reflected in temporal changes in financial charges. The majority of financial burden stemmed from inpatient care. Conclusions: Healthcare financial charges represent a novel phenotype in IBD that reflect trends in classic disease activity parameters and allow for subgroup identification of temporal disease trajectories.

Abstract
BACKGROUND Tobacco smoking is associated with a reduced risk of developing ulcerative colitis (UC). A high proportion of UC patients perceive a benefit in disease outcomes secondary to smoking. However, the effects of smoking on the natural history of UC are uncertain. AIM To conduct a systematic review and meta-analysis of the effects of tobacco smoking on the natural history of UC. METHODS A search of MEDLINE, EMBASE and EMBASE classic was carried out (up to December 2015) to identify observational studies reporting data on smoking and rates of colectomy, flare of disease activity, proximal disease extension, and development of pouchitis following panproctocolectomy and ileal pouch-anal anastomosis in patients with UC. Dichotomous data were pooled to obtain odds ratios (ORs), with 95% confidence intervals (CIs). RESULTS The search identified 16 eligible studies: five (2615 patients) studying colectomy; four (620 patients) reporting on flare of disease activity; four (687 patients) examining proximal disease extension and three (355 patients) assessing development of pouchitis. Compared with nonsmokers, the odds of colectomy (OR = 0.89; 95% CI 0.62-1.26), flare of disease activity (OR = 1.26; 95% CI 0.65-2.44), proximal extension of disease (OR = 0.57; 95% CI 0.20-1.66) or the development of pouchitis (OR = 0.57; 95% CI 0.21-1.53) were not significantly lower in smokers. CONCLUSIONS Smoking may not improve the natural history of ulcerative colitis. Given the health benefits of smoking cessation and the lack of clear benefit in ulcerative colitis, smoking cessation advice should be incorporated into guidance on the management of ulcerative colitis.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a heterogeneous chronic inflammatory condition requiring significant healthcare expenditure. Subgroups of individuals contribute disproportionately to spending. We aimed to determine demographic and clinical factors predictive of high healthcare expenditures for IBD patients followed over a multiyear period. METHODS This was a registry analysis using a prospective observational, consented, natural history registry from a tertiary IBD center and associated medical charges, not including pharmacy expenses. The 100 patients with the highest medical charges (top 5%) were compared with the median 300 patients. Logistic regression determined demographic and clinical factors associated with high charge patients. RESULTS IBD patients in the high charge group had significantly more unemployment (P < 0.0001), were of black race (P = 0.013), comorbid psychiatric illness (P = 0.002), hypertension (P = 0.01), diabetes (P = 0.004), opiate use (P < 0.0001), perianal involvement (P = 0.002), penetrating disease (P < 0.0001), and extensive colitis (P = 0.01). In multivariate analysis, unemployment (Crohn's disease [CD]: odds ratio [OR], 3.04; 95% confidence interval [CI], 1.32-7.02; ulcerative colitis [UC]: OR, 2.68; 95% CI, 1.20-5.99), psychiatric illness (UC: OR, 2.08; 95% CI, 1.03-4.19), opiates (CD: OR, 5.61; 95% CI, 2.67-11.82; UC: OR, 5.14; 95% CI, 2.52-10.48), prior surgery (CD: OR, 3.29; 95% CI, 1.59-6.82; UC: OR, 2.72; 95% CI, 1.39-5.32), penetrating CD (OR, 3.29; 95% CI, 1.02-10.62), and corticosteroid requirement (CD: OR, 3.78; 95% CI, 1.86-7.65; UC: OR, 2.98; 95% CI, 1.51-5.90) remained independently associated with high charges. CONCLUSIONS High expenditure IBD patients were affected by more severe disease. The high prevalence of depression, anxiety, and chronic pain in these patients suggests the need for focused treatment of these comorbidities ultimately to reduce financial burden.

Abstract
BACKGROUND Treatment of ulcerative colitis (UC) is aimed at maintaining corticosteroid-free remission and improving quality of life (QoL). AIM Assess patients' perception of disease burden and unmet clinical needs in moderate/severe UC patients. METHODS Adults surgery-free conventionally treated patients with Mayo score ≥6 were enrolled in an observational, cross-sectional, retrospective study in 11 European countries. Disease control was defined as Mayo score ≤2 with no sub-score >1. No corticosteroid was used the previous two months. Unmet clinical needs were defined as: non-controlled disease, self-perception of 'moderate'/'severe' disease, and dissatisfaction with treatments. Disease burden on QoL and work productivity were assessed (EuroQol-5D-5L, Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and Work Productivity and Activity Impairment (WPAI) in UC questionnaire). RESULTS UC patients (n=253) with mean Mayo score at enrolment of 4.9, 44.3% of patients had Mayo score ≥6. Main treatment was 5-ASA (75%). Overall, 25% met the composite endpoint for unmet clinical needs. Mean (SD) questionnaire scores were: EQ-5D-5L-VAS, 71 (19.1), EQ-5D-5L utility, 0.77 (0.19), SIBDQ, 4.8 (1.3), and WPAI, 26% (32%). CONCLUSIONS Patients with moderate/severe UC in the last 12 months treated with conventional therapies felt that their disease was not controlled and 25% reported unmet clinical needs. QoL and work productivity were seriously impaired.

Danese S, Hart A, Dignass A, Louis E, D'Haens G, Dotan I, Rogler G, D'Agay L, Iannacone C, Peyrin-Biroulet L. Effectiveness of budesonide MMX (Cortiment) for the treatment of mild-to-moderate active ulcerative colitis: study protocol for a prospective multicentre observational cohort study. BMJ Open Gastroenterol 2016; 3:e000092. [PMID: 27239329 PMCID: PMC4873945 DOI: 10.1136/bmjgast-2016-000092] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2016] [Revised: 04/19/2016] [Accepted: 04/24/2016] [Indexed: 12/24/2022] Open
Abstract
INTRODUCTION A study has been developed to assess the use and effectiveness of budesonide MMX for mild-to-moderate active ulcerative colitis (UC) in routine clinical practice. METHODS AND ANALYSIS A prospective, multicentre, observational, cohort study of 300 patients prescribed budesonide MMX for the treatment of mild-to-moderate active UC will be conducted in Europe, Israel and Canada. Patients will be treated with budesonide MMX9 mg daily for induction of remission for ≤8 weeks. Data on effectiveness, including patient-reported outcomes, tolerability and use will be recorded at the end of treatment and at ≥2 weeks after. The primary outcome (improvement ≥3 point in the clinical subscores of the UC Disease Activity Index score at the end of treatment) will be compared in: patients who receive budesonide MMX added to mesalazine >2 weeks after increased/optimised mesalazine dose for the treatment of flare (late add-on); patients who receive budesonide MMX added to mesalazine ≤2 weeks since mesalazine increased/optimised for the treatment of flare, or without mesalazine dose modification (early add-on); and patients who receive budesonide MMX as monotherapy for the treatment of flare (mono). Propensity scoring will be used to minimise bias and confounding inherent in observational studies. ETHICS AND DISSEMINATION First ethical approval: Ethikkommission der Ärztekammer Hamburg (12/22/2015). The results will be published in full. DISCUSSION Completion of primary data collection is expected in December 2017. Our results will provide further evidence on the effectiveness of budesonide MMX to support clinicians in their daily practice and inform therapeutic guidelines. TRIAL REGISTRATION NUMBER NCT02586259.

Abstract
INTRODUCTION Crohn's disease and ulcerative colitis are lifelong illnesses which have a significant impact on quality of life and personal burden through a reduction in the ability to work, sick leave and restrictions of leisure time. The aim of this study was to conduct a systematic review of the indirect costs of Crohn's disease and ulcerative colitis. MATERIAL AND METHODS The search was carried out in Medline, EMBASE, the Centre for Reviews and Dissemination, and reference lists of identified articles and reference lists of identified articles were also handsearched. All costs were adjusted to 2013 USD values by using the consumer price index and purchasing power parity. Identified studies were then analysed in order to assess their heterogeneity and possibility of inclusion in the meta-analysis. RESULTS Eleven of the identified publications presented indirect costs of Crohn's disease or ulcerative colitis. The range of estimated yearly indirect costs per patient was large, from $1 159.09 for loss of earnings to $14 135.64 for lost productivity and sick leave for Crohn's disease. The values for ulcerative colitis ranged from $926.49 to $6 583.17. Because of the imprecise definition of methods of indirect cost calculations as well as heterogeneity of indirect cost components, a meta-analysis was not performed. CONCLUSIONS The indirect costs of ulcerative colitis seem to be slightly lower than in the case of Crohn's disease. A small number of studies referring to indirect costs of Crohn's disease and ulcerative colitis were identified, which indicates the need to conduct further investigations on this problem.

Opportunities for Improvement in the Care of Patients Hospitalized for Inflammatory Bowel Disease-Related Colitis. Dig Dis Sci 2016; 61:1003-12. [PMID: 26860508 PMCID: PMC5716623 DOI: 10.1007/s10620-016-4046-0] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2015] [Accepted: 01/18/2016] [Indexed: 12/23/2022]
Abstract
BACKGROUND Algorithms for the diagnosis, management, and follow-up have been proposed for patients hospitalized for inflammatory bowel disease (IBD) colitis flare. The degree to which providers adhere to these algorithms is unknown. This study evaluated the quality of care in IBD patients hospitalized for disease-associated exacerbations and factors correlated with higher degrees of care. METHODS Retrospective chart review of 34 patients during 60 admissions to the medicine service for IBD colitis exacerbation between 2005 and 2012 at the Veterans Affairs San Diego Medical Center. Examined factors included laboratory testing, timing of consultation and intravenous steroids, abdominal imaging, endoscopic examination, venous thromboembolism (VTE) prophylaxis, narcotic use, Clostridium difficile and cytomegalovirus testing, symptomatology at discharge, timing of follow-up, and rates of readmission and mortality. RESULTS Quality of care varied among the factors studied, ranging from 30.5 % for pharmacologic VTE prophylaxis to 84.7 % for gastroenterology consultation within 24 h. Of 60 admissions, 22 % were not tested for C. difficile. Fifteen percent of patients were discharged before meeting commonly used discharge criteria. Eighty percent were seen in clinic at any time post-discharge; 6.7 % were readmitted; 10 % were lost to follow-up; 1.7 % opted for outside follow-up; and 1.7 % expired. CONCLUSIONS The quality of care for patients admitted with IBD colitis flares is variable. These data outline opportunities for improvement, particularly in regard to pain management, VTE prophylaxis, and follow-up. Further studies are needed to test intervention strategies for practice improvement.

Abstract
GOALS To evaluate the efficacy and safety of mesalamine granules 1.5 g once daily for maintenance of ulcerative colitis (UC) remission. BACKGROUND Mesalamine is a first-line treatment for induction and maintenance of UC remission. STUDY A phase 3, randomized, double-blind, placebo-controlled trial of patients with a history of mild to moderate UC, currently in remission, who received mesalamine granules once daily for 6 months. The primary efficacy endpoint was percentage of patients maintaining UC remission at 6 months. RESULTS A significantly greater percentage of patients receiving mesalamine granules versus placebo were in remission at 6 months (79.9% vs. 66.7%; P=0.03). A greater percentage of patients receiving mesalamine granules maintained a revised Sutherland Disease Activity Index (SDAI)≤2 with no individual component of revised SDAI>1 and rectal bleeding=0 at 6 months (72.0% vs. 58.1%; P=0.04). No significant differences between groups were observed for change from baseline to 6 months for total SDAI score or its components (ie, stool frequency, rectal bleeding, mucosal appearance, physician's rating of disease). Mesalamine granules treatment resulted in a significantly longer remission duration versus placebo (P=0.02) and decreased patients' risk of relapse by 43% (hazard ratio=0.57; 95% confidence interval, 0.35-0.93; P=0.02). Mesalamine granules were well tolerated, and adverse events related to hepatic, renal, and pancreatic function-potential concerns with long-term treatment-occurred at a rate similar to placebo. CONCLUSIONS Once-daily mesalamine granules are efficacious and safe for the maintenance of UC remission.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory condition of the colon, characterized by diffuse mucosal inflammation, bloody diarrhea, and urgency. The mainstay of treatment has been mesalamine agents, steroids, thiopurines, and anti-tumor necrosis factor alpha (TNF-α) antibodies. Over the past several years, new therapies have emerged which have provided clinicians new treatment options as well as new challenges in deciding which treatment is best for their patient at given points in their disease course. These agents include budesonide-Multi-Matrix System (MMX), adalimumab, golimumab, and vedolizumab. In addition, randomized controlled trials have investigated a combination therapy of infliximab and azathioprine and a controlled trial of infliximab versus cyclosporine for intravenous steroid refractory UC. This review will focus on where these agents may be optimally positioned in treatment algorithms for UC.

The Expenditures for Academic Inpatient Care of Inflammatory Bowel Disease Patients Are Almost Double Compared with Average Academic Gastroenterology and Hepatology Cases and Not Fully Recovered by Diagnosis-Related Group (DRG) Proceeds. PLoS One 2016; 11:e0147364.

Abstract
BACKGROUND Crohn's disease (CD) and ulcerative colitis (UC) challenge economies worldwide. Detailed health economic data of DRG based academic inpatient care for inflammatory bowel disease (IBD) patients in Europe is unavailable. METHODS IBD was identified through ICD-10 K50 and K51 code groups. We took an actual costing approach, compared expenditures to G-DRG and non-DRG proceeds and performed detailed cost center and type accounting to identify coverage determinants. RESULTS Of all 3093 hospitalized cases at our department, 164 were CD and 157 UC inpatients in 2012. On average, they were 44.1 (CD 44.9 UC 43.3 all 58) years old, stayed 10.1 (CD 11.8 UC 8.4 vs. all 8) days, carried 5.8 (CD 6.4 UC 5.2 vs. all 6.8) secondary diagnoses, received 7.4 (CD 7.7 UC 7 vs. all 6.2) procedures, had a higher cost weight (CD 2.8 UC 2.4 vs. all 1.6) and required more intense nursing. Their care was more costly (means: total cost IBD 8477€ CD 9051€ UC 7903€ vs. all 5078€). However, expenditures were not fully recovered by DRG proceeds (means: IBD 7413€, CD 8441€, UC 6384€ vs all 4758€). We discovered substantial disease specific mismatches in cost centers and types and identified the medical ward personnel and materials budgets to be most imbalanced. Non-DRG proceeds were almost double (IBD 16.1% vs. all 8.2%), but did not balance deficits at total coverage analysis, that found medications (antimicrobials, biologics and blood products), medical materials (mostly endoscopy items) to contribute most to the deficit. CONCLUSIONS DRGs challenge sophisticated IBD care.

Abstract
Inflammation in inflammatory bowel diseases (IBD) has been linked to a loss of tolerance to self-antigens suggesting the existence of autoantibodies in specific disease phenotypes. However, the lack of clearly defined autoantigenic targets has slowed down research. Genome-wide association studies have identified an impressive number of immune-related susceptibility loci for IBD with no clearly discernible pattern among them. Growing evidence supports the hypothesis that innate immune responses to a low-diversity and impaired gut microbiota may be of key importance in initiating and perpetuating chronic inflammation in IBD. Increasing evidence suggests that reduced microbial diversity and microbial-mucosal epithelium interaction (including adhesion and clearance) are critically involved in IBD pathogenesis. Along these lines the discovery of autoantigenic targets in Crohn's disease (CD) has refocused research in IBD on the possible role of autoimmune responses. The identification of the major zymogen granule membrane glycoprotein 2 (GP2) as an autoantigen in CD patients and its proposed role in the sensing of the microbiota lends credence to this trend. Loss of tolerance to GP2 occurs in up to 40% of patients with CD. Corresponding autoantibodies appear to be associated with distinct disease courses (types or phenotypes) in CD. Here, we critically review autoantibodies in CD for their impact on clinical practice and future IBD research. The immunomodulatory role of GP2 in innate and adaptive intestinal immunity is also discussed.

Abstract
BACKGROUND Etrolizumab (rhuMAb beta7) is an anti-integrin that selectively targets the β7 subunits of the α4β7 and αEβ7 integrins, which are involved in the pathogenesis of ulcerative colitis. OBJECTIVES The objectives of this review were to assess the efficacy and safety of etrolizumab for induction of remission in ulcerative colitis. SEARCH METHODS We searched PubMed, MEDLINE, EMBASE, and the Cochrane Library (CENTRAL) from inception to 12 March 2015. References and conference abstracts were searched to identify additional studies. SELECTION CRITERIA Randomized controlled trials (RCTs) trials in which etrolizumab was compared to placebo or another active comparator in patients with active ulcerative colitis were included. DATA COLLECTION AND ANALYSIS Two authors independently screened studies for inclusion, assessed methodological quality and extracted data. We assessed methodological quality using the Cochrane risk of bias tool. The primary outcome was failure to induce clinical remission (as defined by the primary studies). Secondary outcomes included failure to induce clinical improvement (as defined by the primary studies), failure to induce endoscopic remission (as defined by the primary studies), adverse events, serious adverse events, withdrawal due to adverse events, and health-related quality of life (as defined by the primary studies). We assessed the overall quality of the evidence using the GRADE criteria. We calculated the risk ratio (RR) and corresponding 95% confidence interval (CI) for each dichotomous outcome. MAIN RESULTS Two RCTs including 172 patients with moderate to severe UC who failed conventional therapy met the inclusion criteria. Both studies were rated as low risk of bias. We did not pool efficacy data from the two included studies due to differences in dose and route of administration. The small phase I study found no statistically significant differences between etrolizumab and placebo in the proportion of patients who failed to enter remission (RR 1.04, 95% CI 1.04 to 1.69; participants = 23) or respond at week 10 (RR 1.67, 95% CI 0.26 to 10.82; participants = 23). The phase II study reported on failure to enter clinical remission at weeks 6 and 10. In the etrolizumab group 91% (71/78) of patients failed to enter remission at week 6 compared to 95% (39/41) of placebo patients (RR 0.96, 95% CI 0.87 to 1.06). Subgroup analysis revealed no statistically significant differences by dose. At week 10, there was a statistically significant difference in clinical remission rates favouring etrolizumab over placebo. Of the patients who received etrolizumab, 85% (66/78) failed to enter remission at week 10 compared to 100% (41/41) patients in the placebo group (RR 0.86, 95% CI 0.77 to 0.95). A subgroup analysis by dose found a statistically significant difference in clinical remission rates favoring 100 mg etrolizumab over placebo (RR 0.81 CI 95% 0.68 to 0.96), but not 300 mg etrolizumab over placebo (RR 0.91, 95% CI 0.80 to 1.03). No significant heterogeneity was detected for this comparison (P = 0.28, I(2) = 13.5%). GRADE analyses indicated that the overall quality of evidence for the clinical remission outcomes was moderate due to sparse data. Both of the included studies reported on safety. The outcome adverse events was initially pooled, however this analysis was removed due to high heterogeneity (I(2) = 88%). The phase I study found no statistically significant difference between etrolizumab and placebo in the proportion of patients who had at least one adverse event. Ninety-five per cent (36/38) of etrolizumab patients had at least one adverse event compared to 100% (10/10) of placebo patients (RR 0.98, 95% CI 0.84 to 1.14). Common adverse events reported in the phase I study included exacerbation of UC, headache, fatigue, abdominal pain, dizziness, nasopharyngitis, nausea, arthralgia and urinary tract infection. There was a statistically significant difference between etrolizumab and placebo in the proportion of patients who had at least one adverse event. Fifty-six per cent (44/78) of etrolizumab patients had at least one adverse event compared to 79% of placebo patients (RR 0.71, 95% CI 0.55 to 0.91). A GRADE analysis indicates that the overall quality of the evidence for this outcome was moderate due to sparse data. Common adverse events reported in the phase II study included worsening UC, nasopharyngitis, nervous system disorders, headache and arthralgia . A pooled analysis of two studies indicates that there was no statistically significant difference in the proportion of patients who had a serious adverse event. Twelve per cent (14/116) of etrolizumab patients had a serious adverse event compared to 12% of placebo patients (6/49) (RR 0.92, 95% CI 0.36 to 2.34). A GRADE analysis indicated that the overall quality of the evidence for this outcome was low due to very sparse data (20 events). Common serious adverse events included worsening of UC, impaired wound healing and bacterial peritonitis. AUTHORS' CONCLUSIONS Moderate quality evidence suggests that etrolizumab may be an effective induction therapy for some patients with moderate to severe ulcerative colitis who have failed conventional therapy. Due to small numbers of patients in dose subgroups the optimal dosage of etrolizumab is unclear. Due to sparse data we are uncertain regarding the risk of adverse events and serious adverse events. Further studies are needed to determine the efficacy and safety of etrolizumab in this patient population. There are five ongoing phase III etrolizumab trials and two ongoing open-label extension studies that will provide important new information on the efficacy, safety and optimal dose of this drug for the treatment of UC.

Abstract
BACKGROUND There are limited prospective population-based data on the health care cost of IBD in the post-biologicals era. A prospective registry that included all incident cases of inflammatory bowel disease [IBD] was established to study disease progress and health cost. AIM To prospectively assess health care costs in the first year of diagnosis among a well-characterised cohort of newly diagnosed IBD patients. METHOD Incident cases of IBD were prospectively identified in 2007-2008 and 2010-2013 from multiple health care providers, and enrolled into the population-based registry. Health care resource utilisation for each patient was collected through active surveillance of case notes and investigations including specialist visits, diagnostic tests, medications, medical hospitalisation, and surgery. RESULTS Off 276 incident cases of IBD, 252 [91%] were recruited to the registry, and health care cost was calculated for 242 (146 Crohn's disease [CD] and 96 ulcerative colitis [UC] patients). The median cost in CD was higher at A$5905 per patient (interquartile range [IQR]: A$1571-$91,324) than in UC at A$4752 [IQR: A$1488-A$58,072]. In CD, outpatient resources made up 55% of all cost, with medications accounting for 32% of total cost [15% aminosalicylates, 15% biological therapy], followed by surgery [31%], and diagnostic testing [21%]. In UC, medications accounted for 39% of total cost [of which 37% was due to 5-aminosalicylates, and diagnostics 29%; outpatient cost contributed 71% to total cost. CONCLUSION In the first year of diagnosis, outpatient resources account for the majority of cost in both CD and UC. Medications are the main cost driver in IBD.

Abstract
OBJECTIVES To estimate the management of UC associated costs from the societal perspective in Spain. METHODS Observational, longitudinal study with retrospective data collection based on reviews of outpatient health records. Socio-demographic, clinical and sick leave information was gathered. Patients diagnosed of UC between 2002 and 2012, older than 18 years, followed-up by a minimum of 12 months post diagnosis, with at least two clinical and use of resources data recorded, were included. RESULTS 285 UC patients [51.2% men; 44.5 (SD: 15.6) years old; 88.4% without family history of UC; 39.3% proctitis; 5.6 (2.5) years disease follow-up] participated. More than half (65.6%) were active workers, 75.9% were on sick leave for reasons different from UC [mean 0.66 (0.70) times per year] during (mean) 28.43 (34.45) days. Only 64 patients were on UC-related sick-leaves, lasting (mean) 26.17 (37.43) days. Absenteeism due to medical visits caused loss of 29.55 (21.38) working hours per year. Mean direct and indirect annual cost per UC patient were €1754.10 (95%CI: 1473.37-2034.83) and €399.32 (282.31-422.69), respectively. Absenteeism was estimated at €88.21(32.72-50.06) per patient per year, in which sick-leaves were the main component of indirect costs (88.2%). Age, UC family history, diarrhea at diagnosis, blood and blood-forming organs diseases and psychological disorders were the main predictors of indirect costs. CONCLUSIONS UC is a costly disease for the society and the Spanish National Healthcare System. Indirect costs imply a major burden by affecting the most productive years of patients. Further research is needed considering all components of productivity loss, including presenteeism-associated costs.

Abstract
AIMS AND OBJECTIVES The purpose of this study was to explore the experiences of adults living with ulcerative colitis. BACKGROUND Research to date has focused on the impact of inflammatory bowel disease, by analysing the responses of persons with ulcerative colitis and Crohn's disease collectively. This article addresses the dearth in literature by exploring the experiences of adults living with ulcerative colitis. DESIGN An exploratory qualitative phenomenological design was used. METHOD Semi-structured interviews were conducted with a purposive sample of 10 adults with ulcerative colitis. Verbatim transcripts were analysed using Interpretative Phenomenological Analysis. RESULTS Three super-ordinate themes emerged from the analysis: 'living with physical discomfort', 'emotional turmoil in living the experience' and 'social interactions'. CONCLUSION The participants described a fundamental change in their lifestyle, as a result of physical discomfort and emotional turmoil. Misconceptions held regarding the causes of their disease, further compounded their negative emotional experience. RELEVANCE TO CLINICAL PRACTICE It is of importance that health care professionals understand and explore the unique perspectives of individuals with ulcerative colitis. These perspectives relate to both physical and psychosocial issues. The needs and concerns of persons with ulcerative colitis can then guide the formulation and development of an individualised care plan.

Abstract
BACKGROUND Patients undergoing colectomy for ulcerative colitis (UC) may experience complications associated with reduced quality of life (QoL), and maybe a considerable economic burden to healthcare systems. Appreciation of these burdens is important to evaluate the cost effectiveness of newer interventions for UC vs. colectomy. AIM To identify data representing resource utilisation or costs of complications arising from colorectal procedures in patients with UC, and data representing patient QoL, as reported by health state utility values (HSUVs). METHODS Embase, MEDLINE and The Cochrane Library were searched for studies (1995-2014) reporting resource use/costs of surgical complications, and HSUVs data in adult patients with UC, undergoing colorectal procedures. Conference proceedings (January 2011-January 2014) were hand-searched. RESULTS Twelve studies reported resource use/costs, and three reported HSUVs data in patients with UC experiencing surgical complications. Additional mean costs of postoperative complications ranged from $18 650/patient with complications at a 6-month follow-up (46% incidence) to $34 714/patient with complications over a 5-year period (49% incidence). Pouchitis, pouch failure and small bowel obstruction carried the greatest burden. Marked reductions in HSUVs were observed for patients with UC experiencing surgical complications, vs. patients with UC in a remission state. CONCLUSIONS There is a paucity of well reported studies on resource use/cost, and QoL burden of surgical complications in patients with UC. However, surgical complications represent a substantial burden both in terms of cost and of quality of life, with reoperations, physician fees, additional in-patient hospital stays and infertility treatment being the main cost drivers.

Abstract
OBJECTIVE To assess direct and indirect healthcare resource utilization and costs of privately insured US employees with ulcerative colitis (UC) from a societal perspective. RESEARCH DESIGN AND METHODS Employees aged 18-64 with ≥ 2 UC diagnoses and no more than one diagnosis of Crohn's disease (CD) were identified from a large, de-identified, private insurance US claims database from January 1, 2005 through March 31, 2013. Patients with UC were matched 1:1 to non-IBD controls based on demographics and index date (a randomly selected UC diagnosis). All patients were required to have continuous eligibility for ≥ 1 year before (baseline period) and after (study period) the index date. Descriptive analyses compared baseline characteristics and study period outcomes. Multivariate cost analysis adjusted for baseline comorbidities. Sub-group analyses compared patients with moderate-to-severe UC with matched controls. MAIN OUTCOME MEASURES Costs (2013 US dollars) were measured from a societal perspective, which included direct (patient and payer costs) and indirect (lost wages because of time away from work) costs. RESULTS Patients with UC (n = 4314; mean age = 45.1 years, 63.6% male) had significantly higher baseline comorbidity rates compared with controls. In the study period, significantly more patients with UC (p < 0.0001) had higher hospitalization rates (16.9% vs 6.2%), emergency department visits (31.1% vs 22.0%), prescription drug use (95.3% vs 72.0%), and work loss (100% vs 81.4%). Patients with UC also had significantly higher adjusted total direct ($15,548 vs $4812) and indirect costs ($4125 vs $1961). Patients with moderate-to-severe UC (n = 1728) had significantly (p < 0.0001) higher hospitalization rates (26.5% vs 6.2%) and adjusted total direct ($23,085 vs $4932) and indirect costs ($5666 vs $1960). CONCLUSIONS Patients with UC had higher resource utilization and direct and indirect costs compared with matched controls. The excess burden was greatest in patients with moderate-to-severe UC.

Abstract
Inflammatory bowel disease can impact individuals at a young age, thus compromising their work productivity. Besides the inability to engage in gainful work, the concept of disability also relates to the patients' diminished ability to undertake household and social activities. A literature search was performed of recent literature, and all articles containing information about the impact of inflammatory bowel disease on disability or any work-related outcomes were included. Recent studies suggest that 9 to 19% of inflammatory bowel disease patients suffer from short-term absences from work and 19 to 22% are on long-term disability. Crohn's disease patients reported being more affected by their disease than ulcerative colitis patients. A comparison of results from different studies is difficult due to the lack of consensus on how to define and measure disability. Additional research is needed to better quantify disability in inflammatory bowel disease patients.

Abstract
Curcumin (CUR) is a poorly water-soluble drug and its absorption is very low. In this study, CUR and piperine (PIP) were co-encapsulated into the nanoformulation called self-microemulsifying drug delivery system (SMEDDS) to improve the stability and water-solubility of CUR and enhance its anti-colitis activity. The formulation of CUR-PIP-SMEDDS was prepared to encapsulate two hydrophobic components CUR and PIP, and then was characterized by assessing appearance, morphology, particle size, zeta potential and drug encapsulation efficiency. The appearance of CUR-PIP-SMEDDS remained clarified and transparent, and the microemulsion droplets appeared spherical without aggregation. The mean size of microemulsion droplet formed from CUR-PIP-SMEDDS was 15.87 ± 0.76 nm, and the drug encapsulation efficiency of SMEDDS for CUR and PIP were (94.34 ± 2.18)% and (90.78 ± 2.56)%, respectively. The vitro stability investigation of CUR-PIP-SMEDDS in colon tissue suggested that using SMEDDS as a delivery vehicle and co-encapsulated with PIP, CUR was more stable than drug solution in colons site. Meanwhile, the anti-inflammatory activity of CUR-PIP-SMEDDS was evaluated on DSS-induced colitis model. The results showed that CUR-PIP-SMEDDS exhibited definite anti-colitis activity by directing CUR-PIP-SMEDDS to inflammatory colon tissue through retention enema administration. Our study illustrated that the developed CUR-PIP-SMEDDS formulation was a potential carrier for developing colon-specific drug delivery system of CUR for ulcerative colitis treatment.

Abstract
Biological drugs opened up new horizons in the management of inflammatory bowel diseases (IBD). This study focuses on access to biological therapy in IBD patients across 9 selected Central and Eastern European (CEE) countries, namely Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia. Literature data on the epidemiology and disease burden of IBD in CEE countries was systematically reviewed. Moreover, we provide an estimation on prevalence of IBD as well as biological treatment rates. In all countries with the exception of Romania, lower biological treatment rates were observed in ulcerative colitis (UC) compared to Crohn’s disease despite the higher prevalence of UC. Great heterogeneity (up to 96-fold) was found in access to biologicals across the CEE countries. Poland, Bulgaria, Romania and the Baltic States are lagging behind Hungary, Slovakia and the Czech Republic in their access to biologicals. Variations of reimbursement policy may be one of the factors explaining the differences to a certain extent in Bulgaria, Latvia, Lithuania, and Poland, but association with other possible determinants (differences in prevalence and incidence, price of biologicals, total expenditure on health, geographical access, and cost-effectiveness results) was not proven. We assume, nevertheless, that health deterioration linked to IBD might be valued differently against other systemic inflammatory conditions in distinct countries and which may contribute to the immense diversity in the utilization of biological drugs for IBD. In conclusion, access to biologicals varies widely among CEE countries and this difference cannot be explained by epidemiological factors, drug prices or total health expenditure. Changes in reimbursement policy could contribute to better access to biologicals in some countries.

Abstract
The aim of this systematic review was to collect all current data on indirect costs related to inflammatory bowel disease as well as assessing homogeneity and comparability, and conducting a meta-analysis. Costs were collected using databases from Medline, Embase and Centre for Reviews and Dissemination databases, then average annual cost per patient was calculated and expressed in 2013-rate USD using the consumer price index and purchasing power parity (scenario 1) and then adjusted to specific gross domestic product (scenario 2) to make them comparable. The studies were then included in quantitative synthesis using the meta-analysis and bootstrap methods. This systematic review was carried out and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. From 18 publications, overall annual indirect costs per patient as a result of the quantitative synthesis among all studies eligible for meta-analysis ranged from US$2425.01-US$9622.15 depending on the scenario and model used for analysis. The cost of presenteeism was assessed in only two studies. Considering heterogeneity among all identified studies random-effect model presented the most accurate results of meta-analysis equal to US$7189.27 and US$9622.15 per patient per year for scenario 1 and scenario 2, respectively. This systematic review revealed the existence of a relatively small number of studies that reported on the great economic burden of the disease upon society. A great variety of methodologies and cost components resulted in a very large discrepancy in indirect costs and made meta-analysis difficult to perform, so two scenarios were considered and meta-analysis conducted in subgroups to make data more comparable.

Abstract
BACKGROUND Crohn's disease (CD) is associated with a substantial healthcare burden that affects the patient, healthcare systems and society in general. AIM To provide a systematic evaluation of published data relating to the economic and health-related quality-of-life (HRQoL) burden of CD in selected European countries (Germany, France, UK, Italy, Spain) and the USA since 2000. METHODS We undertook a systematic review of publications relating to CD, its economic burden and impact on HRQoL. Research questions focused on the disease costs from a societal perspective and HRQoL burden in adults and pediatric/adolescent patients according to disease stage/severity. Total, direct and indirect costs were identified, as well as the impact of CD on HRQoL measured using both generic and disease-specific instruments. RESULTS Overall, 61 publications met the research criteria (38 on costs, 23 on HRQoL). CD in the USA and Europe together was associated with annual total costs of nearly <euro>30 billion, more than half due to indirect costs. HRQoL was consistently and statistically significantly lower among CD patients compared with normal populations, due to physical, emotional and social effects. CONCLUSIONS CD is a global health problem with high societal costs and substantial HRQoL burden. High-value care pathways including cost-effective therapies will help to induce and maintain remission, reduce complications of disease and improve HRQoL.

Abstract
BACKGROUND No direct comparison of health care cost in patients with inflammatory bowel disease across the European continent exists. The aim of this study was to assess the costs of investigations and treatment for diagnostics and during the first year after diagnosis in Europe. METHODS The EpiCom cohort is a prospective population-based inception cohort of unselected inflammatory bowel disease patients from 31 Western and Eastern European centers. Patients were followed every third month from diagnosis, and clinical data regarding treatment and investigations were collected. Costs were calculated in euros (€) using the Danish Health Costs Register. RESULTS One thousand three hundred sixty-seven patients were followed, 710 with ulcerative colitis, 509 with Crohn's disease, and 148 with inflammatory bowel disease unclassified. Total expenditure for the cohort was €5,408,174 (investigations: €2,042,990 [38%], surgery: €1,427,648 [26%], biologicals: €781,089 [14%], and standard treatment: €1,156,520 [22%)]). Mean crude expenditure per patient in Western Europe (Eastern Europe) with Crohn's disease: investigations €1803 (€2160) (P = 0.44), surgery €11,489 (€13,973) (P = 0.14), standard treatment €1027 (€824) (P = 0.51), and biologicals €7376 (€8307) (P = 0.31). Mean crude expenditure per patient in Western Europe (Eastern Europe) with ulcerative colitis: investigations €1189 ( €1518) (P < 0.01), surgery €18,414 ( €12,395) (P = 0.18), standard treatment €896 ( €798) (P < 0.05), and biologicals €5681 ( €72) (P = 0.51). CONCLUSIONS In this population-based unselected cohort, costs during the first year of disease were mainly incurred by investigative procedures and surgeries. However, biologicals accounted for >15% of costs. Long-term follow-up of the cohort is needed to assess the cost-effectiveness of biological agents.

Abstract
Refractory distal ulcerative colitis (RDUC) is defined as persistence of symptoms caused by endoscopically proven colonic inflammation located at the rectum or left colon despite oral/topical steroids and 5-ASA. RDUC affects a small subset of patients and is associated with chronic disabling symptoms and increased social/medical costs. Moreover, patients with long-standing ulcerative colitis (UC) carry an elevated risk of developing colorectal cancer and colonic mucosa high-grade dysplasia. Alternative medical strategies in steroid refractory disease are unlikely to provide durable remission in all patients, carry potential severe side effects and, as immunosuppressants, the risk of other neoplasms, and may increase the short-term complication rate when surgery is finally required. Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) allows the complete removal of the diseased rectum and colon, virtually eliminating the risk of malignant transformation and reestablishing intestinal continuity with continence preservation. Since the introduction of this surgical procedure, morbidity and mortality rates have been drastically reduced. Despite the still notable rate of surgical complications, long-term quality of life assessment has shown excellent results in nearly all patients who have undergone RP-IPAA, comparing well with the general population. Furthermore, when performed for distal UC, RP-IPAA produces similar surgical outcomes with respect to pancolitis. In conclusion, RP-IPAA should always be considered in patients with RDUC, and multidisciplinary counseling should provide patients clear information about the advantages of surgery and possible complications as well as the chance to achieve disease remission with medical therapy.

Abstract
BACKGROUND The initial minimum operation for ulcerative colitis is a total abdominal colectomy. Healthy patients may undergo proctectomy at the same time; however, for ill patients, proctectomy is delayed. Since the introduction of biologic medications in 2005, ulcerative colitis medical management has changed dramatically. OBJECTIVE We examined how operative management for ulcerative colitis has changed from the prebiologic to biologic eras. DESIGN We conducted a retrospective review of data on patients with ulcerative colitis who were included in the Nationwide Inpatient Sample database. SETTINGS This study was conducted at a single university. PATIENTS A total of 1,547,852 patients with ulcerative colitis who were admitted to a US hospital from 1991 to 2011 were included in the study. MAIN OUTCOME MEASURES We examined patients whose initial operation consisted of total abdominal colectomy without proctectomy versus a total proctocolectomy with or without a pouch. We also examined which operation was done at the time of the construction of an ileoanal pouch. Patients who underwent colectomy and pouch construction in the same hospitalization were compared with those who received pouch formation at a subsequent hospitalization. RESULTS Ulcerative colitis-related admissions rose by 170% during the years examined, and the number of patients who required total abdominal colectomy increased by 44%. Total abdominal colectomy increased by 15%, as opposed to total proctocolectomy (p < 0.001). Pouch construction at a subsequent operation increased by 16% (p = 0.002). Since 2008, total abdominal colectomy has surpassed total proctocolectomy as the most common initial surgical intervention for ulcerative colitis. LIMITATIONS The Nationwide Inpatient Sample is a retrospective database, and we were limited to examining the variables within it. CONCLUSIONS Total abdominal colectomy is currently the most common initial operation for patients with ulcerative colitis, and an ileoanal pouch is more frequently constructed at a subsequent hospitalization. These trends coincide with the initiation of biologic treatments and may imply that patients are acutely ill at the time of initial operation. Alternately, there may be surgeon-perceived bias of increased surgical risk or a shift in care to specialized surgeons for pouch construction.

Abstract
BACKGROUND & AIMS The burden of ulcerative colitis (UC) in relation to disease severity is not well documented. This study quantitatively evaluated the relationship between disease activity and quality of life (QoL), as well as health care utilization, cost, and work-related impairment associated with UC in an Australian population. METHODS A cross-sectional, noninterventional, observational study was performed in patients with a wide range of disease severity recruited during routine specialist consultations. Evaluations included the Assessment of Quality of Life-8-dimension (AQoL-8D), EuroQol 5-dimension, 5-level (EQ-5D-5L), the disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ), and the Work Productivity and Activity Impairment (WPAI) instrument. The 3-item Partial Mayo Score was used to assess disease severity. Health care resource utilization was assessed by chart review and patient questionnaires. RESULTS In 175 patients, mean (SD) AQoL-8D and EQ-5D-5L scores were greater for patients in remission (0.80 [0.19] and 0.81 [0.18], respectively) than for patients with active disease (0.70 [0.20] and 0.72 [0.19], respectively, both Ps<0.001). IBDQ correlated with both AQoL-8D (r=0.73; P<0.0001) and EQ-5D-5L (0.69; P<0.0001). Mean 3-month UC-related health care cost per patient was AUD $2914 (SD=$3447 [mean for patients in remission=$1970; mild disease=$3736; moderate/severe disease=$4162]). Patients in remission had the least work and activity impairment. CONCLUSIONS More severe UC disease was associated with poorer QoL. Substantial health care utilization, costs, and work productivity impairments were found in this sample of patients with UC. Moreover, greater disease activity was associated with greater health care costs and impairment in work productivity and daily activities.

Abstract
BACKGROUND Ulcerative colitis is a lifelong, chronic, relapsing-remitting disease. OBJECTIVE To assess the relationship between ulcerative colitis disease status and patient quality of life, and to determine the impact of ulcerative colitis on healthcare costs and work productivity, in the UK. METHODS Clinicians assessed 173 adult patients' current disease status at a single study visit using the partial Mayo (pMayo) instrument. Patients completed the Euro Quality of Life 5-dimension, 5-level (EQ-5D-5L) questionnaire, the Work Productivity and Activity Impairment (WPAI) questionnaire. Healthcare resource use was determined from questionnaires and from patients' medical charts. RESULTS Patients in remission had a significantly higher EQ-5D-5L scores (mean (SD) 0.86 (0.15)) than patients with active disease (0.71 (0.20); p<0.001). Patients with mild disease had significantly higher mean (SD) EQ-5D-5L scores than patients with moderate/severe disease: 0.77 (0.11) and 0.66 (0.24), respectively (p<0.001). The mean percent productivity impairment was greater for patients with active disease than for patients in remission on all items of the WPAI questionnaire: 24.6% vs 1.8% for work time missed, 34.1% vs 12.9% for impairment while working, 40.8% vs 14.4% for overall work impairment and 42.7% vs 13.0% for activity impairment (p<0.001 for all comparisons). The mean (SD) total cost of healthcare for ulcerative colitis in the prior 3 months was £1211 (1588). CONCLUSIONS When compared with patients in remission, patients with active ulcerative colitis have significantly worse quality of life and significantly more work impairment. The healthcare costs of ulcerative colitis are considerable.

Abstract
OBJECTIVE Healthcare costs of inflammatory bowel disease are substantial. This study examined the effect of adherence versus non-adherence on healthcare costs in patients with inflammatory bowel disease. METHODS Adults who started infliximab treatment between 2006 and 2009 and had a diagnosis of inflammatory bowel disease were identified from MarketScan Databases. Medication adherence was defined as an infliximab medication possession ratio of 80% or greater in the first year. Mean treatment effects (adherence versus non-adherence) on costs in adherent patients were estimated with propensity-weighted generalized linear models. RESULTS A total of 1646 patients were identified. Significant variables in the model used to develop propensity weights were age, year of infliximab initiation, having Medicare coverage, presence of supplementary diagnoses, office as the place of service for infliximab initiation, prior aminosalicylate use, prior outpatient costs, number of prior outpatient visits, and number of prior colonoscopies. Mean total costs in adherent (n = 674) and propensity-weighted non-adherent (n = 972) patients were $41,713 versus $47,411 overall (p < 0.001), including $28,289 versus $14,889 for infliximab drug costs (p < 0.001), $2458 versus $17,634 for hospitalizations (p < 0.001), $7357 versus $10,909 for outpatient visits (p < 0.001), $236 versus $458 for emergency room visits (p < 0.001), and $3373 versus $3521 for other pharmaceuticals costs (p = 0.460). LIMITATIONS Costs associated with infliximab administration (infusions, adverse events) were captured in healthcare costs (inpatient, outpatient, and emergency room), not in infliximab costs. The influence of adherence on indirect costs (e.g., time lost from work) could not be determined. Reasons for non-adherence were not available in the database. CONCLUSIONS In patients who were adherent to infliximab treatment (a medication possession ratio of 80% or greater in the first year), adherence versus non-adherence was associated with lower total healthcare costs, supporting the overall value of infliximab adherence in patients with inflammatory bowel disease.

Abstract
Ulcerative colitis (UC) is an idiopathic, inflammatory gastrointestinal disease of the colon. As a chronic condition, UC follows a relapsing and remitting course with medical maintenance during periods of quiescent disease and appropriate escalation of therapy during times of flare. Initial treatment strategies must not only take into account current clinical presentation (with specific regard for extent and severity of disease activity) but must also take into consideration treatment options for the long-term. The following review offers an approach to new-onset UC with a focus on early treatment strategies. An introduction to the disease entity is provided along with an approach to initial diagnosis. Stratification of patients based on clinical parameters, disease extent, and severity of illness is paramount to determining course of therapy. Frequent assessments are required to determine clinical response, and treatment intensification may be warranted if expected improvement goals are not appropriately reached. Mild-to- moderate UC can be managed with aminosalicylates, mesalamine, and topical corticosteroids with oral corticosteroids reserved for unresponsive cases. Moderate-to-severe UC generally requires oral or intravenous corticosteroids in the short-term with consideration of long-term management options such as biologic agents (as initial therapy or in transition from steroids) or thiopurines (as bridging therapy). Patients with severe or fulminant UC who are recalcitrant to medical therapy or who develop disease complications (such as toxic megacolon) should be considered for colectomy. Early surgical referral in severe or refractory UC is crucial, and colectomy may be a life-saving procedure. The authors provide a comprehensive evidence-based approach to current treatment options for new-onset UC with discussion of long-term therapeutic efficacy and safety, patient-centered perspectives including quality of life and medication compliance, and future directions in related inflammatory bowel disease care.

Systematic review with network meta-analysis: the efficacy of anti-tumour necrosis factor-alpha agents for the treatment of ulcerative colitis. Aliment Pharmacol Ther 2014; 39:660-71. [PMID: 24506179 PMCID: PMC6979320 DOI: 10.1111/apt.12644] [Citation(s) in RCA: 91] [Impact Index Per Article: 9.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Revised: 12/22/2013] [Accepted: 01/11/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Antibodies against tumour necrosis factor-alpha (anti-TNF) are effective therapies in the treatment of ulcerative colitis (UC), but their comparative efficacy is unknown. AIM To perform a network meta-analysis comparing the efficacy of anti-TNF agents in UC. METHODS After screening 506 studies, reviewers extracted information on seven studies. Traditional meta-analysis (TMA) was used to compare each anti-TNF agent to placebo. Bayesian network meta-analysis (NMA) was performed to compare the effects of anti-TNF agents to placebo. In addition, sample sizes for comparative efficacy trials were calculated. RESULTS Compared to placebo, TMA revealed that anti-TNF agents result in a higher likelihood of induction of remission and response (RR: 2.45, 95% CI: 1.72-3.47 and RR: 1.65, 95% CI: 1.37-1.99 respectively) as well as maintenance of remission and response (RR: 2.00, 95% CI: 1.52-2.62 and RR: 1.76, 95% CI: 1.46-2.14 respectively). Individually, infliximab, adalimumab and goliumumab resulted in a higher likelihood of induction and maintenance for both remission and response. NMA found nonsignificant trends in comparisons of the individual agents. The required sample sizes for direct head-to-head trials between infliximab and adalimumab for induction and maintenance are 174 and 204 subjects respectively. CONCLUSIONS This study demonstrates that, compared to placebo, infliximab, adalimumab and golimumab are all effective for the induction and maintenance of remission in ulcerative colitis. However, network meta-analysis demonstrates that no single agent is clinically superior to the others and therefore, other factors such as cost, safety, route of administration and patient preference should dictate our choice of anti-TNF agents. A randomised comparative efficacy trial between infliximab and adalimumab in UC is of practical size and should be performed.

Abstract
OBJECTIVE Limited evidence is available on the economic burden of ulcerative colitis (UC) in the UK, particularly relating to the impact of relapse frequency on direct medical costs. This study identifies and assesses medical resource utilization (MRU) and associated direct costs in mild and moderate UC patients in the UK. PATIENTS AND METHODS A retrospective chart review of patients with mild-to-moderate UC diagnosed at least 1 year before the study was performed. From 33 general practitioner (GP) and 34 gastroenterologist sites, charts of the last three UC patients fulfilling the inclusion criteria were reviewed. Descriptive statistics were calculated for MRU and 2011 costs (GB£) by number of relapses. RESULTS The study population included 201 patients with a mean age of 39.9 years; 44% were women and the mean disease duration was 7.4 years. UC-related costs of each MRU category increased with the number of relapses. Comparing patients without relapse with those with more than two relapses, the mean annual UC-related costs were £14 versus £2556 for hospitalizations; £218 versus £988 for visits (including nurse, GP, specialist, and other visits); £21 versus £1303 for procedures; £17 versus £188 for diagnostics; and £1168 versus £6660 for all-cause total costs. Age, sex, and site of data reporting (GP vs. gastroenterologist) were not associated with MRU or costs. CONCLUSION Patients with mild-to-moderate UC incurred considerable costs that increased markedly with the number of relapses. These findings support the importance of maintenance therapies in UC that reduce or prevent relapses. Quantifying the relationship between relapse rate and costs will inform future health economic studies.

Abstract
BACKGROUND & AIMS Adalimumab is effective for induction and maintenance of remission in patients with moderate to severe ulcerative colitis (UC). We assessed whether adalimumab, in addition to standard UC therapy, reduced the risk for hospitalization (from all causes, from complications of UC, or from complications of UC or the drugs used to treat it) and colectomy in patients with moderate to severe UC compared with placebo. METHODS Data were combined from patients that received induction therapy (a 160-mg dose followed by an 80-mg dose of adalimumab) or placebo in 2 trials (ULTRA 1 and ULTRA 2; n = 963). The risks of hospitalization and colectomy were compared between groups using unadjusted rates during the 8-week induction period, and patient-year-adjusted rates during 52 weeks. Statistical differences between groups were determined using the χ(2) method and Z score normal approximations. Numbers of hospitalizations were compared using Poisson regression with time offset. RESULTS Significant reductions in risk of all-cause, UC-related, and UC- or drug-related hospitalizations (by 40%, 50%, and 47%, respectively; P < .05 for all comparisons) were observed within the first 8 weeks of adalimumab therapy compared with placebo. Significantly lower incidence rates for all-cause (0.18 vs 0.26; P = .03), UC-related (0.12 vs 0.22; P = .002), and UC- or drug-related (0.14 vs 0.24; P = .005) hospitalizations were observed during 52 weeks of adalimumab therapy compared with placebo. Rates of colectomy did not differ significantly between patients given adalimumab vs placebo. CONCLUSIONS In patients with moderate to severe UC, the addition of adalimumab to standard of care treatment reduced the number of hospitalizations for any cause, as well as for UC-related and UC- or drug-related complications, compared with placebo.

Abstract
Ulcerative colitis (UC) produces bloody diarrhoea, severe abdominal pain, and need for clinic visits, hospitalizations, and surgeries. UC results in reduced health-related quality of life for patients and large direct medical and indirect costs for health systems and employers. Patients with the most severe disease require the most medical services, and these patients have larger costs than patients with mild or moderate disease. Despite biological therapies being quite expensive, they are indicated for patients unresponsive to initial standard therapies. Future hospitalizations may be reduced by starting a biological treatment. Cost-effectiveness results vary between countries, health systems, and model designs. Since restorative proctocolectomy can be curative, this surgery dominates biological therapy by being both less costly and more effective when measuring health system costs and patient quality-adjusted life years for 20 years. However the dose, duration, and effectiveness of biological treatments significantly impact estimates of their cost-effectiveness.

Abstract
Adalimumab is a fully human, recombinant, monoclonal IgG1 antibody specific for the cytokine tumor necrosis factor-α. It is approved for the treatment of patients with inflammatory diseases, including adults with moderately to severely active ulcerative colitis who are refractory to, or intolerant of, corticosteroids and/or immunomodulators. In two well-designed 8- and 52-week clinical trials in patients with moderately to severely active ulcerative colitis despite treatment with corticosteroids and/or immunomodulators, subcutaneous adalimumab (160 mg, week 0; 80 mg, week 2; 40 mg every other week starting at week 4) was more effective than placebo for inducing and maintaining clinical remission. A statistically significant effect size (albeit <10 %) over placebo for the remission per Mayo score (primary endpoint) was observed with adalimumab at 8 weeks in both trials and at 52 weeks in one trial. Compared with placebo, adalimumab was associated with reductions in hospitalizations and improvements in other secondary endpoints, including clinical response, mucosal healing, corticosteroid-sparing, and health-related quality of life measures. Additionally, an early response to adalimumab was shown to be predictive of long-term efficacy. Adalimumab was generally well tolerated, compared with placebo, during clinical trials in patients with ulcerative colitis; the adverse event profile was similar to that in patients with Crohn's disease or other approved indications. Adalimumab provides a new treatment option for patients with moderately to severely active ulcerative colitis who are refractory to, or intolerant of, corticosteroids and/or immunomodulators.

Abstract
BACKGROUND & AIMS Effectiveness of early treatment with biologics and immunomodulator therapy on healthcare utilization remains poorly defined. We assessed rates of hospitalization and surgery within 1 year after initiation of infliximab and/or immunomodulator therapy in a United States cohort of patients with inflammatory bowel disease. METHODS We conducted a retrospective, observational cohort study of veterans with Crohn's disease or ulcerative colitis by using administrative data from 176 Department of Veteran Affairs facilities (October 1, 2001 through September 30, 2009). Inpatient, outpatient, and death records were linked longitudinally with prescription fill data. Each person-day of follow-up was assessed for treatment with infliximab, immunomodulators, both (dual therapy), or neither. We calculated drug exposure time and used Poisson and logistic regression analyses to assess outcomes. RESULTS The cohort of 20,474 patients included 8042 patients with Crohn's disease and 12,432 with ulcerative colitis (93.9% male; 72.5% white; mean age, 60.9 ± 14.5 years) prescribed infliximab (0.17%), immunomodulator (1.3%), or dual therapy (1.5%). Adjusted models revealed 50% relative reductions in hospitalization among patients who received 9.2 months of immunomodulator monotherapy, 8 months of infliximab, or 7.7 months of dual therapy. A 50% relative reduction in surgery was observed among patients receiving 7 months of infliximab or 5 months of dual therapy. Analysis of dose-response data revealed 73.1% and 92% reductions in risk of hospitalization and surgery, respectively, after 9 months of dual therapy. CONCLUSIONS On the basis of a retrospective cohort study, dual therapy with infliximab and an immunomodulator for <8 months is associated with significant reductions in hospitalization and surgery within 1 year of the start of therapy. These findings indicate that patients with IBD are more likely to benefit if dual therapy is initiated earlier in their first year of therapy.

Abstract
BACKGROUND Information on efficacy and predictors of response to adalimumab in ulcerative colitis (UC) clinical practice is limited. AIM Assessment of response to adalimumab and its predictors in an observational cohort study. METHODS Retrospective cohort study based on data obtained from ENEIDA registry. All patients diagnosed with UC treated with adalimumab were included. Response to adalimumab was evaluated at weeks 12, 28, and 54 according to the partial Mayo score, and requirement of colectomy until end of follow-up. RESULTS 48 patients with UC treated with adalimumab were included; 39 (81.3%) had previously received infliximab. Response rates at weeks 12, 28 and 54 were 70.8%, 43.2% and 35% respectively. Response to prior treatment with infliximab was the only predictive factor of response to adalimumab at week 12, which was obtained in 90% of infliximab remitters, 53.8% of responders and 33.3% of primary non-responders (p=0.01). Colectomy was required in 11 patients (22.9%), after a mean time of 205 days. The only clinical independent predictor of colectomy was non-response to adalimumab at week 12: colectomy rates were 5/34 (14.7%) in responders and 6/14 (42.9%) in non-responders (p=0.035), time free of colectomy was significantly reduced in non-responders (p=0.01). Adalimumab withdrawal due to adverse events occurred in 4.2% of patients. CONCLUSION This study shows that adalimumab is an effective treatment in patients with UC. If used as a second anti-TNF, previous achievement of remission with the first anti-TNF predicts response, and failure to achieve response at week 12 predicts colectomy.

Abstract
BACKGROUND Chronic active ulcerative colitis (UC) is associated with significant morbidity, loss of productivity, increased colorectal cancer risk and cost. Up to 18% of patients suffer chronic active disease, with 30% requiring colectomy at 10 years. The management remains challenging given the relatively few clinical trials in this area. AIM To summarise the evidence regarding optimal management strategies for patients with chronic active UC of differing disease extents and degrees of treatment refractoriness. METHOD A literature search using the PubMed and Medline databases was performed. No time limit was set on article publication for inclusion. RESULTS The principles of management should focus on confirming disease activity, exclusion of alternative diagnoses, adherence and treatment escalation. Infliximab and topical tacrolimus are options in refractory proctitis, although the evidence for these therapies is limited. Both infliximab and adalimumab are effective in corticosteroid-refractory disease, although the proportions of patients achieving corticosteroid-free remission remain modest (24% at 30 weeks and 16.9% at 8 weeks respectively). Alternatives include ciclosporin and tacrolimus, and possibly methotrexate. Colectomy often leads to an improved quality of life; medical strategies unlikely to provide durable corticosteroid-free remission should not be pursued. CONCLUSIONS No current pharmacological treatment delivers mucosal healing in the majority of patients. Newer treatments such as vedolizumab and tofacitinib may represent valuable future therapies. Available medical options should be discussed with patients at every step of their management, with an honest appraisal of the evidence. Surgery should always be considered in patients with chronic refractory disease of any extent.

Abstract
BACKGROUND Pediatric ulcerative colitis (UC) care is variable with a lack of appropriate guidelines to guide practice until recently. METHODS UC inpatients <17 years old admitted to 23 U.K. pediatric hospitals had clinical details collected between September 2010 and 2011. Comparative data for 248 patients were available from a previous audit in 2008. RESULTS One hundred and seventy-six patients (98 males) of median age 13 years (interquartile range, 10-13) were analyzed; 23 were elective surgical admissions, 47 new diagnoses, and 106 needed acute medical care for established UC. Median length of stay was 6 days (interquartile range, 3-10) with no deaths. Eighty-eight of 126 patients (70%) with active disease had standard stool cultures performed (3 [2%] were positive), and 57 (45%) had Clostridium difficile toxin tested (none positive). Twenty-five of 66 (38%) emergency admissions had an abdominal x-ray on admission, and 13 of 66 patients (20%) had a Pediatric Ulcerative Colitis Activity Index score. There were 3 cases of toxic megacolon and 2 thromboses. Eighty-one of 116 patients (71%) responded to steroids. Nineteen patients who did not respond adequately to steroids received rescue therapy (7 infliximab, 11 ciclosporin, and 1 both) with overall response rate of 90%; 7 patients needed surgery acutely, 5 without previous rescue therapy. Compared with the 2008 data, stool culture rates improved significantly (86 of 121 [71%] versus 76 of 147 [52%], P = 0.001) as did heparinization rates (15 of 150 [10%] versus 5 of 215 [2%], P = 0.002) and rescue therapy usage (17 of 33 [52%] versus 10 of 38 [26%], P = 0.03). CONCLUSIONS There were signs of improving UC care with significantly increased rates of stool culture and rescue therapy. The majority of sites, however, did not use Pediatric Ulcerative Colitis Activity Index scores.

Gastroenterology 2013; 144:536-43. [PMID: 23232295 DOI: 10.1053/j.gastro.2012.12.004] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2011] [Revised: 11/20/2012] [Accepted: 12/03/2012] [Indexed: 12/15/2022]
Abstract
BACKGROUND & AIMS It is unclear whether colectomy restores the ability of patients with ulcerative colitis (UC) to work to precolectomy levels. We estimated the burden of sick leave and disability pension in a population-based cohort of patients with UC and the effects of colectomy. METHODS We performed a register-based cohort study using the Swedish National Patient Register and identified working-age patients with UC in 2005 (n = 19,714) and patients who underwent colectomies between 1998 and 2002 (n = 807). Sick leave and disability pension data were retrieved from Statistics Sweden (1995-2005). Data from each patient in the study were compared with those from 5 age-, sex-, education-, and county-matched individuals from the general population. RESULTS In 2005, 15% of patients with prevalent UC received a disability pension, compared with 11% of the general population, and 21% vs 13% had ≥1 sick leave episode (P < .001 for each comparison). The annual median work days lost was 0 in both groups, but patients with UC had higher mean (65 vs 45 days; difference, 20; 95% confidence interval [CI], 18-22 days) and 75th percentile work days lost (37 vs 0 days; difference, 37; 95% CI, 36-38 days). Among patients who underwent colectomies, annual days lost increased from a mean of 40 (median, 0) days 3 years before surgery to 141 (median, 99) days during the year of surgery (P < .001). The number then decreased to a mean of 85 days 3 years after surgery (median, 0). The corresponding 75th percentile days were 17, 207, and 130, respectively. Three years after colectomy, 12% did not work at all compared with 7.2% of the general population (risk difference, 5.2%; 95% CI, 2.7%-7.7%) and compared with 5.9% 3 years before colectomy (P < .001). CONCLUSIONS Patients with UC miss more work days than the general population in Sweden. Although most patients had no registered work loss 3 years after colectomy, work loss was not restored to presurgery or general population levels in the group that underwent colectomy during several years of follow-up.

Abstract
BACKGROUND Although high non-adherence to medication has been noticed for ulcerative colitis (UC), little is known about adherence to mesalamine treatments and determinants that can predict adherence. The objective of this study was to assess adherence and persistence to mesalamine treatments and their potential determinants in mild to moderate UC patients in a real-life setting in Quebec, Canada. METHODS A retrospective prescription and medical claims analysis was conducted using a random sample of mesalamine users with UC. For inclusion, patients were required to initiate an oral mesalamine treatment between January 2005 and December 2009. Patients with a diagnosis of Crohn's disease were excluded. Treatment adherence (medication possession ratio [MPR]) and persistence were evaluated over a 1-year period after the index prescription using the Kaplan-Meier method with log-rank test and stepwise regression to identify potential determinants. RESULTS A sample of 1,681 of the new oral mesalamine users (mean age = 55.3) patients was obtained. Overall, the percentage of patients with a MPR of 80% or greater at 12 months was 27.7%, while persistence was 45.5%. Among patients treated with mesalamine delayed/extended-release tablets (Mezavant®), adherence and persistence were 40.9% and 71.9%, respectively. Predictors of high adherence included, male gender (OR=1.3; 95% confidence interval [CI]=1.1-1.6), older age (>60 years; OR=1.6; 95% CI=1.3-2.0) and current use of corticosteroids (OR=1.4; 95% CI=1.1-1.8). Predictors of high persistence included male sex (OR=1.4; 95% CI=1.1-1.7), current use of corticosteroids (OR=1.4; 95% CI=1.1-1.7) and presence of hypertension or respiratory diseases (OR=1.2; 95% CI=1.01-1.55). CONCLUSIONS The majority of patients with UC exhibited low adherence and persistence to mesalamine treatments. Various determinants of improved adherence and persistence were identified.

Abstract
OBJECTIVE The aim of this study was to explore the utilization of health services by Finnish adults with inflammatory bowel disease (IBD) and to assess the associated demographic and health-related quality of life (HRQoL) factors. MATERIAL AND METHODS 556 Finnish IBD patients eligible for reimbursement for IBD medication according to the Social Insurance Institution in Finland answered our postal cross-sectional survey. The study questionnaire included questions about demographic characteristics of the patients, health care resource use, and HRQoL. The number of doctor visits was compared with those of irritable bowel syndrome patients. RESULTS During the previous year, more than three quarters of the respondents reported disturbing IBD symptoms. The majority (64%) had seen a doctor due to their IBD, women more often than men (p < 0.001). The use of health services did not differ between diagnostic (Crohn's disease or ulcerative colitis) or age groups, marital status, education, or time elapsed since diagnosis. Women were absent from work more frequently than men (p = 0.01). The amount of physician visits, work absenteeism, and a higher amount of undergone procedures were related to impaired HRQoL (p < 0.001 on all accounts). CONCLUSIONS Despite comprehensive public health services and specialized care for IBD patients in Finland, a majority expressed disturbing IBD symptoms. Since the amount of physician visits, work absenteeism and a higher amount of procedures were related to a diminished HRQoL, the patients who are most often met by professional caregivers are often those whose HRQoL needs to be more adequately addressed.
