Mesalazine Modified-Release Tablet in the Treatment of Ulcerative Colitis in the Active Phase: A Chinese, Multicenter, Single-Blind, Randomized Controlled Study

Is it time to include older adults in inflammatory bowel disease trials? A call for action

The therapeutic management of older patients with inflammatory bowel disease (IBD) is challenging, particularly because of the absence of evidence-based guidelines for these patients, who seem to frequently be excluded from clinical trials. In this systematic review we investigated the exclusion of older patients with IBD from phase 3 studies registered on PubMed and ClinicalTrials.gov, by assessing the upper limit of age exclusion criteria and the percentage of patients older than 65 years included in the trials. Exclusion criteria other than age were also recorded, and comorbidities were analysed separately. Our review of 222 phase 3 studies shows that older patients are frequently excluded from IBD clinical trials because of their age, which was used as an exclusion criterion in 129 (58%) of the 222 assessed trials. Of the 32 trials that detailed the percentage of included patients who were 65 years or older, only 763 (5·4%) patients of the 14 124 patients included were older than 65 years. In addition to age, patients were also excluded because of comorbidities (mainly renal, hepatic, and cardiovascular, and used as an exclusion criterion in 76% of trials), a history of dysplasia (45% of trials), and previous treatment for IBD (19% of trials). We propose a three-step process that should enable the inclusion of all older patients in IBD clinical trials, regardless of their age, comorbidities, and frailty.

Effect of Kangfuxin Liquid enema combined with mesalazine on gestational outcomes and quality of life in child-bearing female with active ulcerative colitis: A protocol for randomized, double-blind, controlled trial

BACKGROUND

In recent years, the incidence of ulcerative colitis (UC) is on the rise, and most of them are young adults. As the peak of the disease overlaps with the childbearing age, it has a great impact on the fertility of female patients. We, therefore, conduct a randomized and controlled trial to evaluate the efficacy and safety of mesalazine enteric-coated tablets combined with Kangfuxin Liquid (KFX) enema for the child-bearing period female with active UC.

METHODS

In this randomized controlled study, a total of 236 eligible patients will be assigned to the experimental group (n = 118) or the control group (n = 118) in a 1:1 ratio. The control group will be taken mesalazine enteric-coated tablets combined with placebo enema and the experimental group will be taken mesalazine enteric-coated tablets combined with KFX enema. Participants will receive 8 weeks of intervention treatment and 3 months of maintenance treatment before pregnancy. The primary assessment is the Mayo score. Secondary outcomes include mucosal healing, faecal calprotectin (FC), Inflammatory Bowel Disease Quality (IBDQ), and pregnancy outcome.

DISCUSSION

This study will provide evidence regarding the efficacy and safety of KFX enema used before pregnancy on halting active UC, reducing the relapse rate during pregnancy, improving pregnancy outcome, and the quality of life.

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

Nonadherence has been a key barrier to the efficacy of medical treatments in ulcerative colitis (UC). Engaging patients in their IBD care via shared decision-making (SDM) to facilitate self-management may improve adherence to therapy. Areas covered: This review aims to summarize the most recent trial evidence from 2012 to 2017 for mild-to-moderate UC in order to develop clinical algorithms that guide SDM to facilitate self-management. A structured literature search via multiple electronic databases was performed using the search terms 'ulcerative colitis,' 'treatment,' 'management,' 'medication,' 'maintenance,' 'remission,' '5-ASA,' and 'inflammatory bowel disease. Expert commentary: Novel formulations of existing oral and topical medications have expanded the treatment options available for the induction and maintenance therapy for mild-to-moderate UC. Daily dosing of 5-ASA therapy is equivalent to twice daily dosing. The combination therapies of oral plus topical 5-ASA therapy and 5-ASA plus corticosteroid therapy are more effective than monotherapy. Budesonide MMX now plays a role in the management of mild-to-moderate UC. This review collates the evidence on drug efficacy and safety, adherence and tolerability, and noninvasive monitoring of mild-to-moderate UC into SDM-orientated algorithms to facilitate self-management.

Remission endpoints in ulcerative colitis: A systematic review

AIM

To summarize the current consensus on the definition of remission and the endpoints employed in clinical trials.

METHODS

A bibliogragraphic search was performed from 1946 to 2016 sing online databases (National Library of Medicine’s PubMed Central Medline, OVID SP MEDLINE, OVID EMBASE, the Cochrane Library and Conference Abstracts) with key words: (“ulcerative colitis”) AND (“ulcerative colitis endoscopic index of severity” OR “UCEIS”) AND (“remission”) as well as (“ulcerative colitis”) AND (“ulcerative colitis disease activity index”) OR “UCDAI” OR “UC disease activity index” OR “Sutherland index”) AND (“remission”).

RESULTS

The search returned 37 and 116 articles for the UCEIS and UCDAI respectively. For the UCEIS, 12 articles were cited in the final analysis of which 9 validation studies have been identified. Despite the UCEIS has been more extensively validated in all three aspects (validity, responsiveness and reliability), it has been little employed to monitor disease in randomised clinical trials. For the UCDAI, 37 articles were considered for the final analysis. Although the UCDAI is only partially validated, 29 randomised clinical trials were acknowledged to use the UCDAI to determine endpoints and disease remission, though no clear protocol was identified.

CONCLUSION

Although the UCEIS has been more widely validated than the UCDAI, it has not been reflected in the monitoring of disease activity in clinical trials. Conversely, the UCDAI has been used in numerous large clinical trials to define their endpoints and disease remission, however, it is challenging to determine the best possible outcomes due to a lack of homogeneity of the clinical trial protocols. Before determining a gold standard index, international agreement on remission is urgently needed to advance patient care.
