Scoping review on health-related physical fitness in patients with inflammatory bowel disease: Assessment, interventions, and future directions.

BACKGROUND: Reaching the Selecting Therapeutic Targets in Inflammatory Bowel Disease-II (STRIDE-II) therapeutic targets for inflammatory bowel disease (IBD) requires an interdisciplinary approach. Lifestyle interventions focusing on enhancing and preserving health-related physical fitness (HRPF) may aid in improving subjective health, decreasing disability, or even controlling inflammation. However, ambiguity remains about the status and impact of HRPF (i.e. body composition, cardiorespiratory fitness, muscular strength, muscular endurance, and flexibility) in IBD patients, hindering the development of physical activity and physical exercise training guidelines. AIM: To review HRPF components in IBD patients and the impact of physical activity and physical exercise training interventions on HRPF. METHODS: A systematic search in multiple databases was conducted for original studies that included patients with IBD, assessed one or more HRPF components, and/or evaluated physical activity or physical exercise training interventions. RESULTS: Sixty-eight articles were included. No study examined the complete concept of HRPF, and considerable heterogeneity existed in assessment methods, with frequent use of non-validated tests. According to studies that used gold standard tests, cardiorespiratory fitness seemed to be reduced, but findings on muscular strength and endurance were inconsistent. A limited number of studies that evaluated physical activity or physical exercise training interventions reported effects on HRPF, overall showing a positive impact. CONCLUSION: We performed a scoping review using a systematic and iterative approach to identify and synthesize an emerging body of literature on health-related physical fitness in patients with IBD, highlighting several research gaps and opportunities for future research. Findings of this review revealed a gap in the literature regarding the accurate assessment of HRPF in patients with IBD and highlighted important methodological limitations of studies that evaluated physical activity or physical exercise training interventions. This scoping review is a step towards performing studies and systematic reviews in the future, which was not possible at present given the heterogeneity in endpoints and designs of the available studies on this topic. Future well-designed studies are required to determine the optimal training paradigm for improving HRPF in patients with IBD before guidelines can be developed and integrated into the therapeutic strategy.

Cost-Effectiveness Analysis of Increased Adalimumab Dose Intervals in Crohn's Disease Patients in Stable Remission: The Randomized Controlled LADI Trial.

BACKGROUND AND AIMS: We aimed to assess cost-effectiveness of increasing adalimumab dose intervals compared to the conventional dosing interval in patients with Crohn's disease [CD] in stable clinical and biochemical remission. DESIGN: We conducted a pragmatic, open-label, randomized controlled non-inferiority trial, comparing increased adalimumab intervals with the 2-weekly interval in adult CD patients in clinical remission. Quality of life was measured with the EQ-5D-5L. Costs were measured from a societal perspective. Results are shown as differences and incremental net monetary benefit [iNMB] at relevant willingness to accept [WTA] levels. RESULTS: We randomized 174 patients to the intervention [n = 113] and control [n = 61] groups. No difference was found in utility (difference: -0.017, 95% confidence interval [-0.044; 0.004]) and total costs (-€943, [-€2226; €1367]) over the 48-week study period between the two groups. Medication costs per patient were lower (-€2545, [-€2780; -€2192]) in the intervention group, but non-medication healthcare (+€474, [+€149; +€952]) and patient costs (+€365 [+€92; €1058]) were higher. Cost-utility analysis showed that the iNMB was €594 [-€2099; €2050], €69 [-€2908; €1965] and -€455 [-€4,096; €1984] at WTA levels of €20 000, €50 000 and €80 000, respectively. Increasing adalimumab dose intervals was more likely to be cost-effective at WTA levels below €53 960 per quality-adjusted life year. Above €53 960 continuing the conventional dose interval was more likely to be cost-effective. CONCLUSION: When the loss of a quality-adjusted life year is valued at less than €53 960, increasing the adalimumab dose interval is a cost-effective strategy in CD patients in stable clinical and biochemical remission.

The cost of inflammatory bowel disease in high-income settings: a Lancet Gastroenterology & Hepatology Commission.

The cost of caring for patients with inflammatory bowel disease (IBD) continues to increase worldwide. The cause is not only a steady increase in the prevalence of Crohn's disease and ulcerative colitis in both developed and newly industrialised countries, but also the chronic nature of the diseases, the need for long-term, often expensive treatments, the use of more intensive disease monitoring strategies, and the effect of the diseases on economic productivity. This Commission draws together a wide range of expertise to discuss the current costs of IBD care, the drivers of increasing costs, and how to deliver affordable care for IBD in the future. The key conclusions are that (1) increases in health-care costs must be evaluated against improved disease management and reductions in indirect costs, and (2) that overarching systems for data interoperability, registries, and big data approaches must be established for continuous assessment of effectiveness, costs, and the cost-effectiveness of care. International collaborations should be sought out to evaluate novel models of care (eg, value-based health care, including integrated health care, and participatory health-care models), as well as to improve the education and training of clinicians, patients, and policy makers.

Exploring conditions for redistribution of anti-tumor necrosis factors to reduce spillage: A study on the quality of anti-tumor necrosis factor home storage.

BACKGROUND AND AIM: Biologicals are potent drugs for immune-mediated inflammatory diseases. After discontinuation or switch of therapy, many patients have unused biological injectors left. This study aimed to evaluate potential redistribution of unused injectors to prevent spillage of these costly drugs by assessing (i) the quality of transport and home storage through the proportion of injectors stored within the recommended temperature range (2-8 °C) and (ii) acceptance of redistribution by patients. METHODS: All golimumab users, irrespective of the indication, at Maastricht University Medical Center were eligible for inclusion. Patients received golimumab in a sealed bag containing a validated temperature sensor, measuring temperature every 5 min. Patients were asked to store their medication as usual. Deviations from the recommended range were defined as any duration below 0 °C and > 30 min below 2 °C or above 8 °C. After 3 months, patients completed a questionnaire on their opinion towards potential redistribution of unused biologicals. RESULTS: Fifty patients (42.0% male, mean age 53.2 ± 14.3 years) received 276 injectors. The mean storage time was 30.9 ± 33.1 days. Only 11.6% of the injectors were stored within the recommended temperature range. In addition, 11.2% were stored > 30 min below 0 °C and 33.2% were stored > 1 week above 8 °C. Of all patients, 95% would accept redistributed medication when product quality is ensured. CONCLUSIONS: During transport and home storage, only one in eight biological injectors was stored within the recommended temperature range. This hinders redistribution of unused injectors but also raises concern regarding drug effectiveness in immune-mediated inflammatory disease patients.

Multimodal treatment of perianal fistulas in Crohn's disease: seton versus anti-TNF versus advancement plasty (PISA): study protocol for a randomized controlled trial.

BACKGROUND: Currently there is no guideline for the treatment of patients with Crohn's disease and high perianal fistulas. Most patients receive anti-TNF medication, but no long-term results of this expensive medication have been described, nor has its efficiency been compared to surgical strategies. With this study, we hope to provide treatment consensus for daily clinical practice with reduction in costs. METHODS/DESIGN: This is a multicentre, randomized controlled trial. Patients with Crohn's disease who are over 18 years of age, with newly diagnosed or recurrent active high perianal fistulas, with one internal opening and no anti-TNF usage in the past three months will be considered. Patients with proctitis, recto-vaginal fistulas or anal stenosis will be excluded. Prior to randomisation, an MRI and ileocolonoscopy are required. All treatment will start with seton placement and a course of antibiotics. Patients will then be randomised to: (1) chronic seton drainage (with oral 6-mercaptopurine (6MP)) for one year, (2) anti-TNF medication (with 6MP) for one year (seton removal after six weeks) or (3) advancement plasty after eight weeks of seton drainage (under four months anti-TNF and 6MP for one year). The primary outcome parameter is the number of patients needing fistula-related re-intervention(s). Secondary outcomes are the number of patients with closed fistulas (based on an evaluated MRI score) after 18 months, disease activity, quality of life and costs. DISCUSSION: The PISA trial is a multicentre, randomised controlled trial of patients with Crohn's disease and high perianal fistulas. With the comparison of three generally accepted treatment strategies, we will be able to comment on the efficiency of the various treatment strategies, with respect to several long-term outcome parameters. TRIAL REGISTRATION: Nederlands Trial Register identifier: NTR4137 (registered on 23 August 2013).

Pancreatitis-associated protein has no additional value as a marker of disease activity in a real-life cohort of IBD patients.

BACKGROUND AND AIM: Monitoring of mucosal inflammation in inflammatory bowel disease (IBD) is of major importance. New noninvasive markers for intestinal inflammation are needed. Previous studies have reported that pancreatitis-associated protein (PAP) correlates with clinical activity in IBD subgroups. Our aim was to investigate the correlation of serum and fecal PAP with clinical and biochemical parameters of disease activity in a real-life IBD cohort. PATIENTS AND METHODS: Two hundred and five consecutive IBD patients were enrolled. Clinical disease activity was scored by the Harvey-Bradshaw Index or the Simple Clinical Colitis Activity Index; also, C-reactive protein (CRP), erythrocyte sedimentation rate, and fecal calprotectin were determined. As surrogate for endoscopy, a combination score of clinical indices with CRP or calprotectin was used to define active disease. Fecal and serum PAP were measured by ELISA. RESULTS: The median serum and fecal PAP did not differ in Crohn's disease (CD) or ulcerative colitis (UC) patients with active compared with inactive disease according to clinical activity indices. Defining active disease by a combination score of Harvey-Bradshaw Index of more than 4 and CRP of more than 5 mg/l or calprotectin more than 250 µg/g, serum PAP (P=0.01), but not fecal PAP (P=0.32), was significantly higher in active than inactive CD patients. Area under the curve of the corresponding receiver operating curve (ROC) was 0.64. No differences were found in serum or fecal PAP levels using the combination score for active disease in UC. CONCLUSION: Serum but not fecal PAP was higher in active compared with nonactive CD and may reflect mucosal inflammation in CD, but not in UC. However, the accuracy of serum PAP for the diagnosis of active disease was poor, and therefore, serum PAP does not seem to have additional value compared with the current noninvasive markers.
