Algorithms to facilitate shared decision-making for the management of mild-to-moderate ulcerative colitis

Combination of Coptis chinensis polysaccharides and berberine ameliorates ulcerative colitis by regulating gut microbiota and activating AhR/IL-22 pathway

ETHNOPHARMACOLOGICAL RELEVANCE

Coptis chinensis Franch. polysaccharide (CCP) and berberine (BBR) are the primary active components of Coptis chinensis Franch. BBR is clinically used for the treatment of intestinal infections and gastroenteritis. CCP was also reported to be effective for the treatment of ulcerative colitis (UC). However, whether CCP combined with BBR shows a synergistic effect on the treatment of UC has not been elucidated yet.

AIM OF THE STUDY

This study aspired to investigate the therapeutic effect and the possible mechanisms of the combination of CCP with BBR on chronic UC.

MATERIALS AND METHODS

By periodic administration of dextran sulfate sodium (DSS) to C57BL/6J mice, chronic UC model mice were induced. CCP (15 mg/kg), BBR (50 mg/kg), and CCP.BBR (a combination of 15 mg/kg CCP and 50 mg/kg BBR) were orally administered to the model mice for 10 days. Changes of body weight, disease activity index, colon length, organ index, histopathological damage, expression of cytokines, and intestinal tight junction proteins were determined to evaluate the therapeutic effects. 16S rDNA sequencing, targeted short-chain fatty acid metabolomics, qPCR, and western blotting were performed to elucidate the potential mechanism.

RESULTS

Both CCP and BBR alleviated UC via improving colon pathological damage, inhibiting the inflammatory response, and regulating the expression of intestinal tight junction proteins. The combination of CCP with BBR showed a more substantial therapeutic effect via increasing the relative abundance of short-chain fatty acids (SCFAs) producing bacteria, thereby increasing the contents of SCFAs in vivo and activating AhR/IL-22 pathway.

CONCLUSION

The combination of CCP and BBR showed a synergistic effect on the therapy of chronic UC and the mechanism was associated with regulating gut microbiota and activating AhR/IL-22 pathway.

Crohn's disease shared decision making intervention leads to more patients choosing combination therapy: a cluster randomised controlled trial

BACKGROUND

Crohn's disease requires effective patient-clinician communication for successful illness and medication management. Shared decision making (SDM) has been suggested to improve communication around early intensive therapy. However, effective evidence-based SDM interventions for Crohn's disease are lacking, and the impact of SDM on Crohn's disease decision making and choice of therapy is unclear.

AIM

To test the impact of SDM on choice of therapy, quality of the decision and provider trust compared to standard Crohn's disease care.

METHODS

We conducted a multi-site cluster randomised controlled trial in 14 diverse gastroenterology practices in the US.

RESULTS

A total of 158 adult patients with Crohn's disease within 15 years of their diagnosis, with no prior Crohn's disease complications, and who were candidates to receive immunomodulators or biologics, participated in the study. Among these, 99 received the intervention and 59 received standard care. Demographics were similar between groups, although there were more women assigned to standard care, and a slightly shorter disease duration among those in the intervention group. Participants in the intervention group more frequently chose combination therapy (25% versus 5% control, p < 0.001), had a significantly lower decisional conflict (p < 0.05) and had greater trust in their provider (p < 0.05).

CONCLUSIONS

With rapidly expanding medication choices for Crohn's disease and slow uptake of early intensive therapy, SDM can personalise treatment strategies and has the potential to move the field of Crohn's disease management forward with an ultimate goal of consistently treating this disease early and intensively in appropriate patients.

Shared decision-making in the management of patients with inflammatory bowel disease

The rapid progress of research into inflammatory bowel disease (IBD) has resulted in increasingly more treatment options. Different options have different advantages and disadvantages, and the preferences of patients may also differ. If patients can be invited to the formulation of medical decision-making, their compliance and satisfaction would be improved, thus possibly achieving better therapeutic results. The present review aims to summarize the current literature on shared decision-making (SDM) in the management of IBD, with the goal of promoting the application of SDM.

Review article: latent tuberculosis in patients with inflammatory bowel diseases receiving immunosuppression-risks, screening, diagnosis and management

BACKGROUND

One quarter of the world's population has latent tuberculosis infection (LTBI). Systemic immunosuppression is a risk factor for LTBI reactivation and the development of active tuberculosis. Such reactivation carries a risk of significant morbidity and mortality. Despite the increasing global incidence of inflammatory bowel disease (IBD) and the use of immune-based therapies, current guidelines on the testing and treatment of LTBI in patients with IBD are haphazard with a paucity of evidence.

AIM

To review the screening, diagnostic practices and medical management of LTBI in patients with IBD.

METHODS

Published literature was reviewed, and recommendations for testing and treatment were synthesised by experts in both infectious diseases and IBD.

RESULTS

Screening for LTBI should be performed proactively and includes assessment of risk factors, an interferon-gamma releasing assay or tuberculin skin test and chest X-ray. LTBI treatment in patients with IBD is scenario-dependent, related to geographical endemicity, travel and other factors. Ideally, LTBI therapy should be used prior to immune suppression but can be applied concurrently where urgent IBD medical treatment is required. Management is best directed by a multidisciplinary team involving gastroenterologists, infectious diseases specialists and pharmacists. Ongoing surveillance is recommended during therapy. Newer LTBI therapies show promise, but medication interactions need to be considered. There are major gaps in evidence, particularly with specific newer therapeutic approaches to IBD.

CONCLUSIONS

Proactive screening for LTBI is essential in patients with IBD undergoing immune-suppressing therapy and several therapeutic strategies are available. Reporting of real-world experience is essential to refining current management recommendations.

Mesalamine in the Initial Therapy of Ulcerative Colitis

Inflammatory bowel disease is a chronic disorder of intestinal inflammation and includes Crohn's disease and ulcerative colitis. The goal of therapy is to induce and maintain remission, which is achieved with conventional therapies. Mesalamine is considered a first-line therapy for ulcerative colitis. Clinical trials have confirmed its efficacy and safety in patients with mild to moderate ulcerative colitis. Doses of more than 2.4 g/d achieve significantly higher rates of clinical and endoscopic remission, with a decreased risk of relapse. Serious adverse effects are rare, but nonadherence is common. Mesalamine is considered safe in pregnancy, excluding formulations with dibutyl phthalate.

Key Strategies to Optimize Outcomes in Mild-to-Moderate Ulcerative Colitis

Mesalamine (5-ASA) is the mainstay therapy in patients with mild-to-moderate active ulcerative colitis (UC). However, non-adherence to therapy and practice variability among gastroenterologists represent long-standing barriers, leading to poor outcomes. Additionally, targets to treat in UC are increasingly evolving from focusing on clinical remission to achieving endoscopic and histological healing. To date, systemic steroids are still recommended in non-responders to 5-ASA, despite their well-known side effects. Importantly, with the advent of new therapeutic options such as oral corticosteroids with topical activity (e.g., budesonide multimatrix system (MMX)), biologics, and small molecules, some issues need to be addressed for the optimal management of these patients in daily clinical practice. The specific positioning of these drugs in patients with mild-to-moderate disease remains unclear. This review aims to identify current challenges in clinical practice and to provide physicians with key strategies to optimize treatment of patients with mild-to-moderate UC, and ultimately achieve more ambitious therapeutic goals.

A Noninferiority Randomized Clinical Trial of the Use of the Smartphone-Based Health Applications IBDsmart and IBDoc in the Care of Inflammatory Bowel Disease Patients

BACKGROUND

Providing timely follow-up care for patients with inflammatory bowel disease in remission is important but often difficult because of resource limitations. Using smartphones to communicate symptoms and biomarkers is a potential alternative. We aimed to compare outpatient management using 2 smartphone apps (IBDsmart for symptoms and IBDoc for fecal calprotectin monitoring) vs standard face-to-face care. We hypothesized noninferiority of quality of life and symptoms at 12 months plus a reduction in face-to-face appointments in the smartphone app group.

METHODS

Inflammatory bowel disease outpatients (previously seen more often than annually) were randomized to smartphone app or standard face-to-face care over 12 months. Quality of life and symptoms were measured quarterly for 12 months. Acceptability was measured for gastroenterologists and patients at 12 months.

RESULTS

One hundred people (73 Crohn's disease, 49 male, average age 35 years) consented and completed baseline questionnaires (50 in each group). Intention-to-treat and per-protocol analyses revealed noninferiority of quality of life and symptom scores at 12 months. Outpatient appointment numbers were reduced in smartphone app care (P < 0.001). There was no difference in number of surgical outpatient appointments or number of disease-related hospitalizations between groups. Adherence to IBDsmart (50% perfect adherence) was slightly better than adherence to IBDoc (30% perfect adherence). Good acceptability was reported among most gastroenterologists and patients.

CONCLUSIONS

Remote symptom and fecal calprotectin monitoring is effective and acceptable. It also reduces the need for face-to-face outpatient appointments. Patients with mild-to-moderate disease who are not new diagnoses are ideal for this system.

Fecal microbiota transplantation ameliorates active ulcerative colitis

Ulcerative colitis (UC) is a complex chronic pathological condition of the gut in which microbiota targeted treatment, such as fecal microbiota transplantation (FMT), has shown an encouraging effect. The aim of the present study was to investigate the efficacy and safety of FMT in patients with mild or moderate UC. A single-center, open-label study was designed, including 47 patients with mild or moderate active UC who received three treatments of fresh FMT via colonic transendoscopic enteral tubing within 1 week. The inflammatory bowel disease questionnaire, partial Mayo scores, colonoscopy, erythrocyte sedimentation rate, C-reactive protein level and procalcitoin values were used to assess the efficacy of FMT and alteration in gut microbiota was detected by 16S ribosomal RNA-sequencing. Before FMT, microbiota Faecalibacterium prausnitzii (F. prausnitzii) levels were significantly decreased in patients with UC compared with healthy donors (P<0.01). At 4 weeks post-FMT, F. prausnitzii levels were significantly increased (P<0.05), and the Mayo score was significantly decreased (1.91±1.07 at baseline vs. 4.02±1.47 at week 4; P<0.001) in patients with UC compared with healthy donors. Steroid-free clinical responses were reported in 37 patients (84.1%), and steroid-free clinical remission was achieved in 31 patients (70.5%) at week 4 post-FMT, however, steroid-free remission was not achieved in any patient. No adverse events were reported in 41 (93.2%) patients after FMT or during the 12-week follow-up. Shannon's diversity index and Chao1 estimator were also improved in patients with UC receiving FMT. In conclusion, the results of the present study suggested that FMT resulted in clinical remission in patients with mild to moderate UC, and that the remission may be associated with significant alterations to the intestinal microbiota of patients with UC. Furthermore, F. prausnitzii may serve as a diagnostic and therapeutic biomarker for the use of FMT in UC.

Clinical decision support improves quality of care in patients with ulcerative colitis

BACKGROUND

Decision support tools may facilitate shared decision-making and improve quality of care.

AIM

To assess the effectiveness of a decision support tool on improving quality of care in ulcerative colitis.

METHODS

A prospective quality of care intervention was conducted at two Australian hospitals comparing out-patient-based ulcerative colitis care with, and without, a tablet-based decision support tool. This included questions on disease activity management; psychological well-being; and preventive care, with 13 process indicators relevant to each domain. Participants included adult out-patients with mild-to-moderate ulcerative colitis and their clinicians who were divided into two cohorts. The first cohort were followed up immediately after their clinical review to check whether their clinician had discussed the 13 process indicators during the consultation. The second cohort of patients used the decision support tool immediately prior to their consultation which then generated a suggested management plan for the patient and clinician to discuss during the consultation. Management between the 2 cohorts was compared to assess the effectiveness of the decision support tool in improving the primary outcome, defined as the proportion of quality process indicators used for ulcerative colitis care, with and without the decision support tool.

RESULTS

Thirteen physicians and 100 patients participated. Fifty patients were managed without the decision support tool using standard care (median age 40; 44% male), and 50 patients used the decision support tool (median age 40; 46% male) over a 20-week period. Increase in the median use of process indicators overall was observed following use of the decision support tool (27% vs 100%; P < 0.001). Improvements were seen in psychological well-being management (30% vs 100%; P < 0.001), preventive care (16% vs 100%; P < 0.001) and process indicators related to disease activity management (50% vs 100%; P < 0.001). The decision support tool was found to be usable and acceptable. Shared decision-making was greater in the post-intervention group (mean decision conflict score of 18.0 vs 33.5; P = 0.002).

CONCLUSIONS

The decision support tool substantially improved the quality of the delivery of care. Decision support tools have the potential to minimise errors of omission via a standardised approach to care.
