Background: Patients with Ehlers-Danlos syndrome-hypermobility type (EDS-HT) have increased prevalence of gastrointestinal (GI) symptoms, particularly reflux and dyspepsia. EDS-HT is associated with dysautonomia, psychopathology, and chronic pain which can be associated with GI symptoms. The association between GI symptoms and EDS-HT in a 'non-patient' population and the effect of the above-mentioned factors has never been studied., Methods: In a cross sectional study, a hypermobility questionnaire was used to screen university students; further clinical examination established the diagnosis of EDS-HT. Validated questionnaires assessed for GI, somatic, pain and autonomic symptoms, psychopathology and quality of life (QOL). These were compared in students with and without EDS-HT; logistic regression analysis examined associations between EDS-HT, GI symptoms and other variables., Key Results: Of 1998 students screened, 162 were included: 74 EDS-HT (21.0 years, 53% female) vs 88 Non-EDS-HT (21.5 years, 65% female). Compared to non-EDS-HT students, EDS-HT students were more likely to have multiple GI symptoms (41.9% vs 27.3% P=.05), particularly postprandial fullness (34.4% vs 15.9%, P=.01) and early satiety (32% vs 17%, P=.03), greater autonomic (P<.001) and somatic symptoms (P=.04) but not psychopathology (P>.8). The association between EDS-HT and postprandial symptoms was dependent on autonomic factors but independent of pain and psychopathology. Pain-related QOL scores were reduced in the EDS-HT group (80 vs 90, P=.03)., Conclusions and Inferences: The previously described association between EDS-HT, dyspepsia, pain and autonomic symptoms in patients is also present in non-patient groups. Future studies are necessary to explore the etiological role of connective tissue in GI and extra intestinal symptoms., (© 2016 John Wiley & Sons Ltd.)

Background The overlap of unexplained gastrointestinal ( GI) and somatic symptoms is well established in patients with functional gastrointestinal disorders ( FGID). Joint hypermobility syndrome ( JHS) is a non-inflammatory connective tissue disorder associated with GI and somatic symptoms. We aimed to determine whether there is an association between diagnosis of JHS and FGID and the impact of this association on comorbidities and quality of life ( QOL). Methods Prospective case-control study in secondary care GI clinics over 2 years. JHS was assessed by the first author prior to consultation in 641 consecutive new patients. Diagnosis of FGID (cases, n = 336) or organic disorders (controls, n = 305) was established blind to JHS status. JHS prevalence was compared in cases ( FGID patients) and controls (organic disorders patients). Extra-intestinal comorbidity and QOL were compared in FGID patients with and without JHS. Key Results JHS prevalence was higher in FGID compared to organic GI disorders (39.0% vs 27.5%, ORadj: 1.51, CI: 1.07-2.12, p = 0.02), and particularly associated with functional gastroduodenal disorders (44.1%, ORadj: 2.08, CI: 1.25-3.46, p = 0.005), specifically postprandial distress syndrome (51%, ORadj: 1.99, CI: 1.06-3.76, p = 0.03). FGID patients with JHS had increased chronic pain (23.2% vs 11.9%, p = 0.01), fibromyalgia (10.5% vs 3.1%, p = 0.01), somatization scores (13 vs 10, p < 0.001), urinary autonomic scores (30.5 vs 20.7, p = 0.03), and worse pain-related QOL scores (45.0 vs 63.5, p = 0.004). Conclusions & Inferences JHS is significantly associated with FGID, and this subgroup of patients have increased comorbidity and decreased QOL. Further research is required to understand the pathophysiological basis of this association. [ABSTRACT FROM AUTHOR]
