There is an evidence that increased capillary permeability in the standing position is related to a deficit in the sympathetic nervous system. The leakage of this fluid leads to various clinical conditions which frequently puzzle the consulting physician because despite the frequency of this condition intelligent physicians and patients are unaware of the cause of their condition. One of the most common manifestations is the inability to lose weight despite proper dieting. A randomized study comparing the efficacy of a diuretic, a converting enzyme inhibitor, spironolactone and a sympathomimetic amine on weight loss in diet refractory women found that only the latter in the form of dextroamphetamine sulfate demonstrated significant weight reduction over a six month time span. In fact, the dextroamphetamine sulfate proved effective when given in the next 6 months to the three groups failing to respond for the first 6 months. The diagnosis of a deficit in sympathomimetic amines is established by demonstrating an abnormal clearance of a water load in the erect position and exclusion of other conditions that are associated with an abnormal free water clearance, e.g., hypothyroidism, renal or liver disease or congestive heart failure. The original definition of an abnormal water load test was excretion of <55% of a 1500 ml water load in 6h but we found that <75% defines a greater population who suffer from this problem. There are several conditions that have proven refractory to conventional theory that respond quickly and effectively to sympathomimetic amines. There have been many anecdotal reports of relieving interactable pain syndromes quickly and efficiently with sympathomimetic amine theory, despite failure with a multitude of other therapies. These include interstitial cystitis and pelvic pain that was attributed to endometriosis, gastrointestinal pain including esophagitis and gastroparesis, headaches, joint pain, fibromyalgia, and carpal tunnel syndrome. It is not clear if the improvement in pain is related to a decrease in fluid retention or a direct effect of the sympathomimetic amines on the sympathetic nervous system. Sympathomimetic amine theory has helped other conditions besides pain, e.g., chronic fatigue, vasomotor symptoms in young women not associated with decreased ovarian egg reserve, and chronic urticaria resistant to all other therapies. Thus, these studies strongly suggest that physicians be aware of this condition involving a deficit in the sympathetic nervous system when faced with various enigmatic complaints especially if standard therapy has not proven effective.

Introduction Ehlers-Danlos syndrome (EDS), specifically the hypermobility type (hEDS), is associated with a variety of gastrointestinal (GI) conditions. This study aims to evaluate the prevalence of and factors associated with gut dysmotility in patients with hEDS. Methods This is a retrospective study of hEDS patients conducted at the Cleveland Clinic's Center for Personalized Genetic Healthcare between January 2007 and December 2017. Demographics, GI motility testing, endoscopic, and imaging data were extracted from the patients' charts. Results A total of 218 patients with hEDS were identified. Among them, 136 (62.3%) patients had at least one GI symptom at the time of EDS diagnosis. Motility testing was performed and reported in 42 (19.2%) patients. Out of them, five (11.9%) had esophageal dysmotility, 18 (42.8%) had gastroparesis, five (11.9%) had small bowel/colon altered transit time, and four (9.5%) had global dysmotility. In univariable analysis, patients with postural orthostatic tachycardia syndrome (POTS) [odds ratio (OR): 8.88, 95% CI: 3.69-24.9, p<0.0001], fibromyalgia (OR: 4.43, 95% CI: 2.04-10.1, p=0.0002), history of irritable bowel syndrome (OR: 5.01, 95% CI: 2.31-11.2, p<0.0001), and gastroesophageal reflux disease (OR: 3.33, 95% CI: 1.55-7.44, p=0.002) were more likely to be diagnosed with GI dysmotility. On multivariable analysis, only POTS (OR: 5.74, 95% CI: 2.25-16.7, p=0.0005) was significantly associated with an increased likelihood of GI dysmotility. Conclusions This study suggests that GI symptoms are relatively common among patients with hEDS. Of the patients tested for dysmotility, 76.2% were found to have some form of dysmotility. POTS was found to be an independent predictive factor for GI dysmotility.
