  1. Ehlers-Danlos Syndromes Emily Chang AM report May 18, 2009

  2. What is it? • A group of inherited disorders with wide phenotypic variability but that involve primarily connective tissues • Often involved are skin, joints, and blood vessel walls • Defects are caused by genetic mutations affecting collagen production • There are 6 major types (but LOTS of variability)

  3. General Symptoms • Stretchy skin • Flexible joints with hypermobility • Hernias • Abnormal wound healing/stretching scars • Joint dislocations • Easy bruising • Muscle weakness • Heart and vascular problems such as aneurysms, MVP, aortic root dilatation • Uterine and intestinal rupture

  4. Joint and Skin Findings

  5. Differential Diagnoses • Marfan Syndrome • Benign Hypermobility Joint Syndrome • Diagnosed by Beighton score, Beighton criteria • Loeys-Dietz Syndrome • Stickler Syndrome • Williams Syndrome • Aarskog-Scott Syndrome • Fragile X Syndrome • Achondroplasia, hypochondroplasia

  6. Classical Type (Types I & II) • Generalized hyperextensibility of joints and skin • Easy bruising, hemarthroses • Poor wound healing and retention of sutures • Congenital dislocation of hips • Scoliosis • MVP

  7. Hypermobility Type (Type III) • Most common type (1 in 10-15,000) • Joint hyperextensibility • Chronic degenerative joint disease • Less skin involvement • Advanced premature OA with pain • MVP

  8. Vascular Type (Type IV) • Most serious type (1 in 250,000) • Prone to ruptured/dissected arteries and aneurysms, intestinal and uterine rupture • Easy bruising • Visible veins beneath thin, translucent skin • Protruding eyes, thin nose/lips, sunken cheeks, small chin • Joint involvement variable • Relative deficiency in type III collagen

  9. Kyphoscoliosis Type (Type VI) Arthrochalasia Type (Type VIIA/VIIB) Dermatosparaxis Type (Type VIIC)

  10. Genetic Inheritance • Primarily Autosomal Dominant • Kyphoscoliosis and dermatosparaxis types are inherited in Autosomal Recessive pattern

  11. Diagnosis • Family History/Pedigree • Physical Exam/History • ECHO • DEXA • Skin biopsy for vascular type • Urine test for kyphoscoliosis type • Genetic testing for classical, vascular, kyphoscoliosis and arthrochalasis types • Can do prenatal and pre-implantation testing

  12. Family Tree 45 AAA 28 aortic aneurysm, aneurysm of kidney ? 69 28 AA 31 AA, cerebral hemorrhage 44 28 AA 45 ?valve replacement 13 aortic aneurysm

  13. Complications • Scarring (molluscoid pseudotumors) • Difficulty healing surgical wounds and sutures that tear out • Chronic joint pain and joint dislocations • Eye problems – globe rupture • Premature rupture of membranes • Rupture/dissection of major vessels or organs (uterine, intestinal, aortic)

  14. Treatment • Managing sx and preventing complications • Rehabilitation – PT/OT, aquatic therapy • Patient education • Body mechanics • NSAIDs, chronic pain management • Orthopedics and possible role for braces • Antibiotic prophylaxis if MVP • Minimize trauma and meticulous hemostasis during surgery • Genetic counseling
