Response to clinical and genetic aspects of Ehlers-Danlos syndrome, classic type


To the Editor: I read with interest the review of the clinical and genetic aspects of Ehlers-Danlos syndrome (EDS) by Malfait et al.1 This otherwise excellent review was weakened by the cursory discussion of pain associated with EDS. The authors do not include assessment and characterization of pain in the recommendations for initial evaluation, and pain is only briefly mentioned in management of musculoskeletal manifestations (Antiinflammatory drugs may help with joint pain), prevention of musculoskeletal manifestations (Individuals with muscle hypotonia and joint instability with chronic pain may have to adjust lifestyle and professional choices accordingly), and under emotional support (Emotional support and behavioral and psychological therapy may be indicated to accept and cope...with the long-term chronic pain). Chronic pain has long been recognized as a clinically important manifestation in all types of EDS.2,3 The pain is severe, unremitting, and significantly impacts activities of daily living, sleep, energy levels, and quality of life.3–5 More recently, systematic study of pain in EDS has better characterized the contribution of clinical factors to pain in these patients.3 Dislocations, joint hypermobility, and previous surgery in ascending order of importance were significantly associated with pain.3 Despite these studies, the actual cause of the pain in EDS remains unknown. The patients with EDS followed through my clinic have generally had extensive (and expensive) evaluations including batteries of rheumatologic tests and many imaging studies. Most have been on multiple pain medications, both over the counter and prescription including narcotics, with poor results. They uniformly express frustration as their providers are unfamiliar with EDS and are unaware of the chronic pain associated with the diagnosis. This coupled with the lack of objective findings of joint inflammation or degeneration results in the patients being labeled as hypochondriacs or drug seekers. Referring these patients to multidisciplinary pain clinics and educating the providers at these clinics about EDS and the pain associated with it has resulted in objective improvement in patient’s day to day ability to function and subjective improvement in coping and mood. Medication use is generally less and is safer. To date, no studies have evaluated the relative effectiveness of pain management strategies in EDS. Multidisciplinary pain clinics are considered the standard of care for management of patients with chronic, complex pain.6 I think that all patients with EDS should be asked about pain as a routine part of the initial evaluation. All patients with pain that requires regular medication, that interferes with activities of daily living or sleep, or that is identified as affecting quality of life should be referred to a multidisciplinary pain clinic for evaluation and treatment. Furthermore, medical geneticists are obliged to educate the pain clinic about EDS and the pain associated with it. Our lack of understanding of the mechanism of the pain should provide the impetus for more research in this area with the hope that improved treatment would follow.
