Ehlers-Danlos Syndrome Diagnosis and Management

Diagnostic Criteria

The diagnosis of hypermobile EDS (hEDS) requires meeting all three major clinical criteria: Beighton score ≥5/9 for joint hypermobility, soft/velvety skin without fragility, and exclusion of alternative diagnoses through genetic testing, as recommended by the Genetics in Medicine society 1
Joint hypermobility is assessed using the Beighton scale score ≥5/9 points, which includes passive dorsiflexion of fifth fingers >90°, passive thumb apposition to flexor forearm surface, elbow hyperextension >10°, knee hyperextension >10°, and forward bend with palms flat on floor, knees extended, according to the Genetics in Medicine society 1
Skin characteristics include soft or velvety texture with normal or slightly increased extensibility, as noted by the Genetics in Medicine society 1
Absence of skin/soft tissue fragility is essential to distinguish hEDS from other EDS subtypes, as stated by the Genetics in Medicine society 1
Autosomal dominant family history without skin abnormalities is a supportive minor criterion, as reported by the Genetics in Medicine society 1
Recurrent joint dislocations or subluxations, chronic joint or limb pain, easy bruising, functional bowel disorders, and neurally mediated hypotension or postural orthostatic tachycardia syndrome are also supportive minor criteria, according to the Genetics in Medicine society 1

Physical examination should document Beighton score, skin characteristics, and tissue fragility, as recommended by the Genetics in Medicine society 1
Family history should include a three-generation pedigree focusing on joint hypermobility and connective tissue features, according to the Genetics in Medicine society 1
Echocardiogram should be performed to evaluate for aortic root dilatation, which occurs in 25-33% of classic and hypermobility types, as noted by the Genetics in Medicine society 1
Baseline vascular imaging is essential for vascular EDS-specific evaluation, using non-invasive methods such as Doppler ultrasound, CT, or MRI, as recommended by the Praxis Medical Insights society 2

Cardiovascular surveillance is crucial, with echocardiogram every 2-3 years until adult height is reached, and repeat if cardiovascular symptoms develop or major physical activity increase is planned, as recommended by the Genetics in Medicine society 1
For aortic root dilation, echocardiogram should be performed every 6 months if diameter >4.5 cm in adults or growth rate >0.5 cm/year, according to the Genetics in Medicine society 1
Vascular EDS requires annual surveillance imaging for any dilated or dissected segments, as recommended by the Praxis Medical Insights society 2
Low-resistance exercise and physical therapy are essential for musculoskeletal management, as reported by the Genetics in Medicine society 1
Proton pump inhibitors, H2-blockers, or sucralfate are recommended for gastritis and reflux, while promotility agents are used for delayed gastric emptying, according to the Genetics in Medicine society 1
Celiprolol is recommended to reduce vascular morbidity in vascular EDS, although it lacks FDA approval in the US, as noted by the Praxis Medical Insights society 2
Avoid invasive vascular procedures due to fatal complication risk, as warned by the Praxis Medical Insights society 2

Do not diagnose hEDS without genetic testing to exclude alternative diagnoses, as 26.4% of clinically diagnosed cases had alternative genetic conditions requiring different management, according to the Praxis Medical Insights society 2
Avoid invasive diagnostic procedures in vascular EDS, using non-invasive imaging exclusively due to fatal complication risk, as recommended by the Praxis Medical Insights society 2
Do not escalate to invasive nutrition support in hEDS with pain-predominant presentation, as most hEDS patients have visceral hypersensitivity rather than true dysmotility, as reported by the Gut society 3, 4
Avoid opioid dependence for chronic pain management, particularly problematic in patients with gastrointestinal manifestations, as warned by the Praxis Medical Insights society 2
Do not overlook associated conditions, screening for POTS, mast cell activation disorder, and chronic urinary retention, as recommended by the Gut society 3, 4

The American Heart Association notes that aortic root dilation occurs in 25-33% of hypermobile EDS cases, highlighting the need for regular cardiovascular monitoring 5
Patients with hypermobile EDS may experience osteoporosis, scoliosis, and congenital hip dislocation, with short stature present in 44% of cases, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases 5

The National Institute of Neurological Disorders and Stroke reports that postural orthostatic tachycardia syndrome (POTS) is common in hypermobile EDS, manifesting as orthostatic intolerance 5
Up to 98% of hypermobile EDS patients experience GI manifestations, including reflux, abdominal pain, constipation, and bloating, as noted by the American Gastroenterological Association 5

Vascular Ehlers-Danlos syndrome (Type IV) directly causes renal arterial complications, including aneurysms and dissections, due to COL3A1 mutations, which can manifest as renal artery aneurysms that may rupture spontaneously without significant dilation, according to the American Heart Association 6, 7
The connection between EDS and kidney disease is most clearly established in vascular EDS (Type IV), where COL3A1 mutations cause structural weakness in arterial walls throughout the body, including renal arteries, as stated by the American College of Cardiology 6, 7

A separate connection exists between autosomal dominant polycystic kidney disease (ADPKD) and intracranial aneurysms, which occurs in approximately 8% of ADPKD patients, as reported by the American Stroke Association 8
COL4A1 gene mutations can cause hereditary angiopathy with nephropathy, aneurysm, and muscle cramps syndrome, which represents a distinct genetic condition that shares features with EDS but is not classified as EDS, according to the American Heart Association 8

For Vascular EDS with Renal Involvement, baseline MRI or CT imaging from head to pelvis is recommended to evaluate the entire aorta and branch vessels, including renal arteries, as suggested by the American College of Cardiology 6, 7
Annual surveillance imaging is recommended for any dilated or dissected segments in patients with Vascular EDS, as stated by the American Heart Association 6, 7
