Functional dyspepsia (FD) often co-exists with joint hypermobility syndrome (JHS), characterized by decreased gastric accommodation and lower nutrient tolerance compared to FD patients with JHS.
Functional dyspepsia (FD) is defined as the presence of gastroduodenal symptoms in the absence of organic disease that is likely to explain the symptoms. Joint hypermobility (JH) refers to the increased passive or active movement of a joint beyond its normal range and is characteristically present in patients with joint hypermobility syndrome (JHS), which is a hypermobile subtype of Ehlers-Danlos syndrome (EDS). Recent reports have highlighted the co-existence of FD with Ehlers-Danlos syndrome. Our aim was to study the prevalence of JHS in FD compared with healthy subjects and to study the impact of co-existing JHS on gastric motility, nutrient tolerance, and dyspeptic symptoms in FD. Methods FD patients filled out a dyspepsia symptom severity score. Intragastric pressure (IGP) was measured with high-resolution manometry (HRM) during the intragastric infusion of nutrition drink (ND, 1.5 Kcal/ml, 60 ml/min) until maximal satiation in healthy subjects and FD. We compared IGP profiles and nutrient tolerance in HS and FD with or without JHS. Results JHS was present in 54% of FD patients (n = 39, 41.2 +/- 2.2 years old) and 7% of healthy subjects (n = 15, 27.3 +/- 2.3 years old). IGP drop and nutrient tolerance were lower in non-JHS-FD compared with JHS-FD and HS (AUC JHS-FD: -17.9 +/- 2.5 vs. non-JHS-FD: -13.0 +/- 3.3 mmHg min, p = 0.2, HS:-19.6 +/- 2.9 mmHg min; ND tolerance non-JHS-FD: 671.0 +/- 96.0 vs. JHS-FD: 842.7 +/- 105.7 Kcal, p = 0.25, HS: 980.0 +/- 108.1 Kcal). Conclusion JHS often co-exists with FD. Non-JHS-FD was characterized by decreased accommodation and lower nutrient tolerance characterized compared with JHS-FD.
