Extra-articular symptoms, including headaches, are frequently encountered in patients with Ehlers-Danlos syndrome (EDS) and hypermobility spectrum disorders (HSD), and may be the presenting complaint. Migraine is reported in up to three quarters of patients with symptomatic joint hypermobility, have a higher headache frequency, and an earlier age of onset compared to the general population. Orthostatic headache is an important presentation, and should raise suspicion of an underlying spinal cerebrospinal fluid leak, dysautonomia, and craniocervical pathology, which are all associated with heritable connective tissue disorders (HCTD) including EDS.

Article Synopsis
  • The study examined how often and how severely people with Ehlers-Danlos syndromes (EDS) and hypermobility spectrum disorders (HSD) experience issues related to swallowing (dysphagia), voice (dysphonia), and acid reflux.
  • A total of 1620 participants, primarily female with a mean age of 38, completed online surveys measuring their symptoms, with results analyzed through statistical methods (ANOVAs).
  • Findings revealed that those with hypermobile EDS (hEDS) reported worse symptoms compared to those with HSD, highlighting the need for healthcare professionals to be aware of these throat-related issues for better management and treatment plans.

Background: Hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD) are debilitating conditions. Diagnosis is currently clinical in the absence of biomarkers, and criteria developed for adults are difficult to use in children and biologically immature adolescents. Generalized joint hypermobility (GJH) is a prerequisite for hEDS and generalized HSD.

Experts in symptomatic generalized joint hypermobility (S-GJH) agree that upper cervical instability (UCI) needs to be better recognized in S-GJH, which commonly presents in the clinic as generalized hypermobility spectrum disorder and hypermobile Ehlers-Danlos syndrome. While mild UCI may be common, it can still be impactful; though considerably less common, severe UCI can potentially be debilitating. UCI includes both atlanto-occipital and atlantoaxial instability.

The Ehlers-Danlos Society Extension for Community Health Care Outcomes (EDS ECHO) is a portfolio of teleconferencing programs developed around the principles and practices of Project ECHO®, aimed at increasing awareness of Ehlers-Danlos syndromes (EDS) and hypermobility spectrum disorders (HSD) among clinicians, enhancing their confidence in the assessment and management of these complex conditions, and generating networks of clinicians across specialties. We assessed the outcomes of the first EDS ECHO program, launched in April 2019, with two hub locations: Indiana University Health, Indianapolis, Indiana, USA, and The Royal Society of Medicine, London, UK. Clinicians were surveyed before and 6 months after their participation.

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.

Dysautonomia (autonomic dysfunction) occurs in the Ehlers-Danlos syndromes (EDS) and hypermobility spectrum disorders (HSD). Symptoms include palpitations, dizziness, presyncope, and syncope, especially when standing upright. Symptoms of orthostatic intolerance are usually relieved by sitting or lying and may be exacerbated by stimuli in daily life that cause vasodilatation, such as food ingestion, exertion, and heat.

In late 2017, the global nonprofit, The Ehlers-Danlos Society (TEDS), was awarded a "Pipeline to Proposal" Tier A award from the Patient-Centered Outcomes Research Institute (PCORI). The goal of this application was to form a team of patients, researchers, other community support groups and stakeholders who are focused on establishing the Ehlers-Danlos Comorbidity Coalition to address the common health issues associated with this group of high morbidity, high disease burden conditions. The ongoing Coalition that is now funded by individual donors and expanding in its mission and members, is an example of successful collaboration spanning over borders and priorities.

The 2017 classification of Ehlers-Danlos syndromes (EDS) identifies three types associated with causative variants in COL1A1/COL1A2 and distinct from osteogenesis imperfecta (OI). Previously, patients have been described with variable features of both disorders, and causative variants in COL1A1/COL1A2; but this phenotype has not been included in the current classification. Here, we expand and re-define this OI/EDS overlap as a missing EDS type.

Article Synopsis
  • People with Ehlers-Danlos Syndromes (EDS) often experience inadequate pain relief during dental procedures despite using local anesthetics (LAs), and this study aimed to explore these experiences more systematically.
  • An online survey conducted among EDS patients and their friends revealed that 88% of EDS respondents felt their pain wasn’t sufficiently managed by LAs, compared to only 33% of non-EDS patients.
  • The study found that among different anesthetic agents, articaine was reported to be the most effective for EDS individuals, although still only 30% experienced satisfactory pain relief.

Context: The Ehlers-Danlos Syndromes (EDSs) are a set of rare heritable disorders of connective tissue, characterized by defects in the structure and synthesis of extracellular matrix elements that lead to a myriad of problems including joint hypermobility and skin abnormalities. Because EDS affects multiple organ systems, defining clear boundaries and recognizing overlapping clinical features shared by disease phenotypes is challenging.

Objectives: The objective of this study was to seek evidence of phenotypic subgroups of patients with distinctive symptom profiles and describe these resulting subgroups.

Purpose Of Review: Joint hypermobility is a common, although largely ignored physical sign. Joint hypermobility is often asymptomatic but may be a feature of an underlying genetic disorder with systemic manifestations. The present article presents a comprehensive approach to considering joint hypermobility and clinically related issues in children and adults.

Autonomic dysfunction contributes to health-related impairment of quality of life in the hypermobile type of Ehlers-Danlos syndrome (hEDS). Typical signs and symptoms include tachycardia, hypotension, gastrointestinal dysmotility, and disturbed bladder function and sweating regulation. Cardiovascular autonomic dysfunction may present as Orthostatic Intolerance, Orthostatic Hypotension, Postural Orthostatic Tachycardia Syndrome, or Neurally Mediated Hypotension.

In the last decade, growing attention has been placed on joint hypermobility and related disorders. The new nosology for Ehlers-Danlos syndrome (EDS), the best-known and probably the most common of the disorders featuring joint hypermobility, identifies more than 20 different types of EDS, and highlights the need for a single set of criteria to substitute the previous ones for the overlapping EDS hypermobility type and joint hypermobility syndrome. Joint hypermobility is a feature commonly encountered in many other disorders, both genetic and acquired, and this finding is attracting the attention of an increasing number of medical and non-medical disciplines.
