Objective: Joint hypermobility in Ehlers-Danlos Syndromes (EDS) predisposes persons with EDS to frequent subluxations and dislocations, chronic arthralgia, and soft-tissue rheumatism. Epidemiologic trends of rheumatologic conditions among persons with EDS are lacking. Prescription claims databases can reflect underlying disease burdens by using medication claims as disease proxies. We examined the prevalence of prescription claims for commonly prescribed immunomodulator and antiinflammatory (IMD) drugs among persons with EDS compared with their matched control person, and hypothesized peripubertal increases among female persons with EDS.
Methods: We compared the percentages of IMD drug prescription claims among 3,484 persons with EDS (ages 5-62 years) against their age-, sex-, state of residence-, and earliest claim date-matched control persons using 10 years (2005-2014) of private prescription claims data and a minimum 2-year enrollment inclusion criterion.
Results: Our cohort comprised 70% adults and 74% female persons. At least 1 IMD medication was prescribed to 65.4% of persons with EDS compared with 47.4% of control persons. We observed 1.3 to 4.2 times higher odds (P < 0.0001) for 5 out of 6 IMD drug classes among persons with EDS compared with matched control persons, except for biologic agents (conditional odds ratio 1.3, 95% confidence interval 0.8-2.0). Peripubertal increases were observed for nonsteroidal antiinflammatory drugs, oral, and injectable steroids.
Conclusions: To our knowledge, our study is the first to examine the full range of IMD drug prescription claim trends among persons with EDS. We believe our research findings can have notable diagnostic and management implications for EDS patients who present with multiple comorbidities and generally require a more granular assessment of their medical conditions.
