Comprehensive Motility Analysis in Patients with Hypermobility Spectrum Disorders and Gastrointestinal Symptoms: An...

Disorders of gut-brain interaction (DGBI) affect up to 40% of people worldwide and in several studies an association with hypermobility spectrum disorders (HSD) was described. HSD patients frequently report gastrointestinal (GI) symptoms and GI dysmotility has been suggested as underlying mechanism. This study evaluates whether individuals with (undiagnosed) joint hypermobility and/or HSD show different GI symptom and motility patterns compared to those without hypermobility/HSD.

In this prospective open-label study, patients who were referred for GI motility assessment between 2016 and 2018 were included. Motility assessments included esophageal manometry, gastric emptying test, antro-duodenal manometry, colonic manometry, and/or a colonic transit study. Joint hypermobility was assessed using the Beighton score, and HSD was diagnosed using the Brighton criteria. Symptom severity, anxiety and depression, and quality of life were evaluated through validated questionnaires.

Eighty-seven participants were included (73 women, median age 42.0 years), and categorized into HSD (n = 23) and non-HSD (n = 64), with further subdivision by Beighton cut-off values (≥ 4, and ≥ 6). GI symptom scores were high, with 37% of the total population exhibiting depressive symptoms (HADS ≥ 8), and 32% experiencing anxiety. Quality of life scores were generally low, with a physical composite score of 26.9 (13.2) and a mental composite score of 47.3 (17.1). Across all comparisons, no significant differences in GI symptoms or motility patterns were found between all groups.

This exploratory tertiary care study found no distinct GI symptom or dysmotility patterns between patients with and without hypermobility/HSD. Further research is warranted to investigate whether GI dysmotility is related to hypermobility.
