Ehlers–Danlos syndromes, hypermobility spectrum disorders, and associated co‐morbidities: Reports from EDS ECHO
Abstract
In both community care and across a broad range of hospital specialties, many healthcare professionals (nurses, midwives, physical and other therapists, psychologists, and doctors) will likely attend to people with Ehlers–Danlos syndromes (EDS) or hypermobility spectrum disorders (HSD). The belief that EDS is rare or ultra-rare is true for several forms of the syndrome, but increasingly the hypermobile type of EDS (hEDS) is thought more common, and HSD (a population previously described within joint hypermobility syndrome prior to the 2017 nosology changes; Castori et al., 2017; Tinkle et al., 2017) much more common. Together the prevalence of hEDS and HSD is likely greater than 1 in 500 in the general population (Demmler et al., 2019), and a common presentation in general musculoskeletal clinics (Grahame & Hakim, 2006). Yet often the journey to diagnosis and treatment is challenging for patients, who may receive no diagnosis, or misdiagnoses. In addition, misconceptions that the issues are solely mental health concerns are commonly reported. Too often there is more than a decade delay in diagnosis, and the negative impact on quality of life from living with under-managed disease is significant (Bell & Pearce, 2021; Berglund, Pettersson, Pigg, & Kristiansson, 2015; Castori, Camerota, Celletti, Grammatico, & Padua, 2010; Demmler et al., 2019; Mu et al., 2019). Multiple morbidities can arise from structural pathologies throughout the body in EDS. These pathologies include musculoskeletal, dermatological, neurological, ocular, oro-dental, laryngeal, pulmonary, gastrointestinal, vascular, and uro-gynecological disorders. Symptoms of chronic widespread pain and chronic fatigue are almost universal (Hakim et al., 2020; Schubart, Schaefer, Hakim, Francomano, & Bascom, 2019). The phenotype, in part, depends on the type of EDS, but features can overlap between them, most clearly seen in the musculoskeletal system and skin, for example. These pathologies have been well documented and are increasingly understood through the determination of their molecular genetics and the ensuing abnormalities of collagens and other molecules of the extracellular matrix (Malfait et al., 2017). In HSD, the principal structural morbidity is in the musculoskeletal system, sharing similar concerns to EDS in presenting with joint instability, ease of joint injury, musculoskeletal, and neuropathic pain, and chronic fatigue (Castori et al., 2017). In addition, several co-morbidities are associated with EDS and HSD. These include disorders of autonomic function, gastrointestinal function, neurodevelopment, mental health, and inflammation and systemic manifestations of mast cell activation. In 2017, alongside the new criteria for EDS and the framework for diagnosing HSD, the International Consortium on the EDS and HSD published a series of review articles exploring what was known of the associations and management of many of these co-morbidities in these conditions (Tinkle, Malfait, Francomano, & Byers, 2017). These and more areas of health concern continue to be explored. Recent large population and registry data affirm their high prevalence in EDS and HSD (Boris & Bernadzikowski, 2021; Cederlöf et al., 2016; Demmler et al., 2019; Hakim et al., 2020; Ritelli, Venturini, Cinquina, Chiarelli, & Colombi, 2020; Schubart et al., 2019), and reports also describe similar severity of co-morbidities in hEDS and HSD (Aubry-Rozier et al., 2021; Copetti et al., 2019; Hakim, 2019). With substantial growth in knowledge in the field, keeping up to date with advances in epidemiology, pathophysiology, and management of this heterogeneous group of conditions is challenging. No individual healthcare professional can truly manage all aspects of these conditions at an expert level. Care typically requires a holistic and multidisciplinary approach. Yet such care, ideally embedded in the community, supported by subspecialty medical, therapies, and social care (Whitty et al., 2020) is substantially lacking for EDS and HSD internationally. Currently, there are small numbers of expert clinics, centers, and networks striving to support patients and colleagues. Access to care is profoundly limited, yet management of many of the common concerns is well within the ability of most generalists with specialist support when needed. Recognizing the exponential growth in knowledge, the multifaceted challenges faced by healthcare systems internationally, and the need for greater numbers of healthcare professionals to feel informed and confident in the diagnosis and management of EDS and HSD, the Ehlers-Danlos Society in 2019 established EDS ECHO, an affiliate of Project ECHO® (Project ECHO, 2021; The Ehlers-Danlos Society, 2021). Project ECHO's philosophies include "all teach, all learn" and "move knowledge, not people." The ECHO model primarily seeks to increase access to care. Embracing this, EDS ECHO has established several programs for healthcare professionals and for commu

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
