Background & aims: The Joint Hypermobility Syndrome (JHS) is a common connective tissue disorder characterized by joint hyperflexibility, dysautonomia, and chronic pain. Gastrointestinal (GI) symptoms are reported in JHS patients attending rheumatology clinics, but the prevalence and symptom pattern of previously undiagnosed JHS in GI clinics are unknown.
Methods: By using validated questionnaires, a prospective cross-sectional study in secondary care GI clinics estimated the prevalence of JHS in new consecutively referred patients, compared GI symptoms in patients with and without JHS, and by using multiple regression determined whether the burden of GI symptoms in JHS patients was dependent on chronic pain, autonomic, psychological, and medication related factors. A positive control group consisted of JHS patients referred from rheumatology clinics with GI symptoms (JHS-Rh).
Results: From 552 patients recruited, 180 (33%) had JHS (JHS-G) and 372 did not (non-JHS-G). Forty-four JHS-Rh patients were included. JHS-G patients were more likely to be younger, female with poorer quality of life (P = .02) than non-JHS-G patients. After age and sex matching, heartburn (odds ratio [OR], 1.66; confidence interval [CI], 1.1-2.5; P = .01), water brash (OR, 2.02; CI, 1.3-3.1; P = .001), and postprandial fullness (OR, 1.74; CI, 1.2-2.6; P = .006) were more common in JHS-G vs non-JHS-G. Many upper and lower GI symptoms increased with increasing severity of JHS phenotype. Upper GI symptoms were dependent on autonomic and chronic pain factors.
Conclusions: JHS is common in GI clinics, with increased burden of upper GI and extraintestinal symptoms and poorer quality of life. Recognition of JHS will facilitate multidisciplinary management of GI and extra-GI manifestations.
