What Is Ehlers-Danlos Syndrome (EDS)?
Ehlers-Danlos Syndrome (EDS) refers to a group of disorders that affect the body’s connective tissue, including skin, tendons, ligaments and blood vessel walls. These connective tissues provide strength and elasticity to other parts of the body.
Children who have EDS typically have overly flexible joints. They sometimes also have fragile, stretchy skin. A more severe form of the disorder, known as vascular EDS, can cause ruptured blood vessel walls, intestines or other organs.
What Causes Ehlers-Danlos Syndrome?
Certain types of EDS are caused by abnormalities in the genes that produce the most important protein in our connective tissue. This protein, called collagen, gives strength and structure to connective tissues. Other forms of EDS come from abnormalities in genes that produce other proteins that work together with collagen.
A family history of the condition is also a risk factor for developing EDS.
What Are the Types of Ehlers-Danlos Syndrome?
There are six major types of EDS:
The most common type of EDS. Hypermobility is when the joints move beyond the normal range for that joint.
One of the most common types of EDS. Causes skin fragility, easy bruising, skin hyperelasticity, joint hypermobility and scarring.
The most serious type of EDS, and extremely difficult to diagnose. Type 4 can cause blood vessels or organs to rupture. Children who have vascular EDS often have distinctive facial features, such as a thin nose, thin upper lip, small earlobes and prominent eyes.
Very rare. Causes generalized joint hypermobility, frequent joint dislocations, skin hyperelasticity, easy bruising, tissue fragility, low muscle tone and low bone mineral density.
Also very rare. Causes severe skin fragility, easy bruising and sagging, doughy skin.
Ehlers-Danlos Syndrome Symptoms and Effects
The most common symptoms of EDS are:
- Loose, overly flexible joints.
- Hypermobility in the toes, hands and fingers.
- Small, fragile blood vessels.
- Abnormal scar formation.
- Wounds that don’t heal easily.
- Abnormally stretchy, fragile skin that bruises easily.
- Early arthritis.
- Muscle weakness and pain.
- Joint pain.
- Fatty lumps at pressure points (knees and elbows).
- Heart valve problems.
Ehlers-Danlos Syndrome Diagnosis and Treatment
If your child has EDS, a specialist usually gives a diagnosis only after reviewing medical and family history and performing a physical exam. Experts might also perform a genetic test using a blood or skin sample to confirm the diagnosis.
Although there is no cure for EDS, Gillette Children’s offers the following treatments, which can help manage your child’s symptoms and prevent further complications.
Medicines, such as ibuprofen or naproxen, can help control your child’s pain. For more severe joint and muscle pain, we occasionally prescribe stronger medicines. If your child has fragile blood vessels, we might recommend blood pressure medicine to keep blood pressure low.
It happens rarely, but if your child still experiences joint dislocations after trying conservative treatments, we might recommend surgery to repair the joint.
If your child has EDS, Gillette experts will customize a treatment that fits your specific needs. To help manage related conditions, your child might also see some of our specialists in areas such as:
