Somatic Comorbidity in Chronic Constipation: More Data from the GECCO Study

A Rome Working Team Report on Brain-Gut Behavior Therapies for Disorders of Gut-Brain Interaction

BACKGROUND AND AIMS

This Rome Foundation Working Team Report reflects the consensus of an international interdisciplinary team of experts regarding the use of behavioral interventions, specifically brain-gut behavior therapies (BGBTs), in patients with disorders of gut-brain interaction (DGBIs).

METHODS

The committee members reviewed the extant scientific literature and, when possible, addressed gaps in this literature through the lens of their clinical and scientific expertise. The Delphi method was used to create consensus on the goals, structure, and framework before writing the report. The report is broken into 5 parts: 1) definition and evidence for BGBT, 2) the gut-brain axis as the mechanistic basis for BGBT, 3) targets of BGBTs, 4) common and unique therapeutic techniques seen in BGBT, and 5) who and how to refer for BGBT.

RESULTS

We chose to not only review for the reader the 5 existing classes of BGBT and their evidence, but to connect DGBI-specific behavioral targets and techniques as they relate directly, or in some cases indirectly, to the gut-brain axis. In doing so, we expect to increase gastrointestinal providers' confidence in identifying and referring appropriate candidates for BGBT and to support clinical decision making for mental health professionals providing BGBT.

CONCLUSIONS

Both gastrointestinal medical providers and behavioral health providers have an opportunity to optimize care for DGBIs through a collaborative integrated approach that begins with an effective patient-provider relationship, thoughtful communication about the brain-gut axis and, when appropriate, a well communicated referral to BGBT.

EFFICACY AND SAFETY OF INTESTINAL SECRETAGOGUES FOR CHRONIC CONSTIPATION: A SYSTEMATIC REVIEW AND META-ANALYSIS

BACKGROUND

Intestinal secretagogues have been tested for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome. The class-effect of these type of drugs has not been studied.

OBJECTIVE

To determine the efficacy and safety of intestinal secretagogues for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome.

METHODS

A computer-based search of papers from 1966 to September 2017 was performed. Search strategy consisted of the following MESH terms: intestinal secretagogues OR linaclotide OR lubiprostone OR plecanatide OR tenapanor OR chloride channel AND chronic constipation OR irritable bowel syndrome. Data were extracted as intention-to-treat analyses. A random-effects model was used to give a more conservative estimate of the effect of individual therapies, allowing for any heterogeneity among studies. Outcome measures were described as Relative Risk of achieving an improvement in the symptom under consideration.

RESULTS

Database Search yielded 520 bibliographic citations: 16 trials were included for analysis, which enrolled 7658 patients. Twelve trials assessed the efficacy of intestinal secretagogues for chronic constipation. These were better than placebo at achieving an increase in the number of complete spontaneous bowel movements per week [RR 1.87 (1.24-2.83)], at achieving three or more spontaneous bowel movements per week [RR 1.56 (1.31-1.85)] and at inducing spontaneous bowel movement after medication intake [RR 1.49 (1.07-2.06)]. Similar results were observed when assessing the efficacy of intestinal secretagogues on constipation-predominant irritable bowel syndrome based on the results of six trials.

CONCLUSION

Intestinal secretagogues are useful and safe therapeutic alternatives for the treatment of constipation-related syndromes.
