A review of Ehlers-Danlos syndrome
Ehlers-Danlos syndrome (EDS) describes a group of heritable disorders of connective tissue comprising mutations in the genes involved in the structure and/or biosynthesis of collagen. Thirteen EDS subtypes are recognized, with a wide degree of symptom overlap among subtypes and with other connective tissue disorders. The clinical hallmarks of EDS are tissue fragility, joint hypermobility, and skin hyperextensibility. Appropriate diagnosis of EDS is important for correct multidisciplinary management and is associated with better clinical outcomes for patients.

Rare Cases of PLOD1-Related Kyphoscoliotic Ehlers-Danlos Syndrome in a Korean Family Identified by Next Generation Sequencing.
We describe the rare cases of kEDS in Korean siblings with two novel compound heterozygous variants, c.926_934del (p.Leu309_Leu311del) and c.2170_2172del (p.Phe724del) in the PLOD1 gene. They had congenital hypotonia, joint laxity, skin hyperextensibility, Marfanoid habitus, high myopia and atrophic scarring. The younger sibling had an early-onset progressive kyphoscoliosis, while the older sibling showed mild scoliosis during childhood. Intrafamilial variability of the clinical severity and age of kyphoscoliosis onset observed in our cases. PMID: 32174067 [PubMed - in process] (Source: Journal of Korean Medical Science)

Rome IV Functional Gastrointestinal Disorders and Health Impairment in Subjects With Hypermobility Spectrum Disorders or Hypermobile Ehlers-Danlos Syndrome
Individuals with hypermobility spectrum disorder or hypermobile Ehlers-Danlos Syndrome (HSD/hEDS) are increasingly encountered by gastroenterologists and pose complex clinical challenges. Uncontrolled studies have found functional gastrointestinal disorders (FGIDs) to be common in patients with HSD/hEDS. Some patients have somatic symptoms (medically unexplained symptoms) that might affect FGIDs. We performed a case –control study to determine the prevalence of and factors associated with Rome IV FGIDs in subjects with HSD/hEDS compared with age- and sex- matched population-based controls.

An old drug for a rare disease: The example of celiprolol for vascular Ehlers-Danlos syndrome.
Abstract Vascular Ehlers-Danlos syndrome (OMIM 130050, 1/150,000 birth) is caused by mutations in collagen 3A1 gene. It is associated with severe phenotype associating early arterial dissection and rupture, digestive and uterine perforations, and skin and joints fragility. Until recently, no treatment was available. Celiprolol, a beta1 antagonist with beta2 partial antagonist properties betablocker was tested in a randomized, controlled trial. We could show that this compound was associated with a 3-fold decrease in major events related to the disease. This effect was similar in molecular-prove...

Survey of Ehlers ‒Danlos Patients’ ophthalmic surgery experiences
ConclusionsPatients with EDS may have elevated risk of postoperative ophthalmic surgical complications. It would seem reasonable to systemically and prospectively explore how patients with EDS respond to ophthalmic surgery. Furthermore, it would seem circumspect to ask surgical candidates patients about whether they carry a diagnosis of EDS or have signs and symptoms of EDS prior to surgery.

Quantitative measures of tissue mechanics to detect hypermobile Ehlers-Danlos syndrome and hypermobility syndrome disorders: a systematic review
AbstractHypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD) are heritable connective tissue disorders associated with pain, activity limitations and participation restrictions. A key feature is reported to be reduced stiffness and increased extensibility and elasticity of connective tissues. Yet diagnosis relies on assessment of joint range of motion, which may be influenced by other factors, and semi-quantitative assessment of forearm skin extensibility. The objective of this systematic review was to determine if quantitative measures of tissue mechanics can discriminate between hEDS...

The Many Facets of Hypermobile Ehlers-Danlos Syndrome.
Authors: Riley B Abstract Of the 13 subtypes of Ehlers-Danlos Syndromes (EDSs) identified in the 2017 international classification of EDSs, 12 have a recognized, associated genetic mutation. However, hypermobile EDS (hEDS) currently has no identifiable associated gene. Therefore, patients with hEDS are identified through a set of clinical diagnosis guidelines and criteria, which are meant to differentiate hEDS from other hypermobile joint conditions and other EDSs subtypes. In this article, the authors provide an overview of hEDS symptoms and comborbidities, current treatment options, and the clinical criteria curr...

Targetable cellular signaling events mediate vascular pathology in vascular Ehlers-Danlos syndrome
Vascular Ehlers-Danlos syndrome (vEDS) is an autosomal-dominant connective tissue disorder caused by heterozygous mutations in the COL3A1 gene, which encodes the pro-α 1 chain of collagen III. Loss of structural integrity of the extracellular matrix is believed to drive the signs and symptoms of this condition, including spontaneous arterial dissection and/or rupture, the major cause of mortality. We created 2 mouse models of vEDS that carry heterozygous mutations in Col3a1 that encode glycine substitutions analogous to those found in patients, and showed that signaling abnormalities in the PLC/IP3/PKC/ERK pathway (p...

Hypomorphic zebrafish models mimic the musculoskeletal phenotype of β4GalT7-deficient Ehlers-Danlos syndrome.
In conclusion, we generated the first viable animal models for spEDS-B4GALT7, and show that in early development the human spEDS-B4GALT7 phenotype is faithfully mimicked in these zebrafish models. Our findings underscore a key role for β4GalT7 in early development of cartilage, bone and muscle. These models will lead to a better understanding of spEDS-B4GALT7 and can be used in future efforts focusing on therapeutic applications.

Celiprolol Treatment of Patients With Vascular Ehlers-Danlos Syndrome
Introduction: Vascular Ehlers-Danlos syndrome (vEDS) is a monogenetic disease caused by a mutation in procollagen 3A1. Clinical manifestations are arterial ruptures and dissections, as well as spontaneous ruptures of the colon, oesophagus and uterus. Expected survival is short, in historical cohorts approximately 50 years. In 2010 a French-Belgian randomized controlled trial (RCT), including 53 patients, reported a hazard ratio of only 0.36 of arterial events if patients were treated with the betablocker celiprolol , combining β1-adrenoceptor antagonist and β2-adrenoceptor agonist actions.

Tenascin X (TNX) deficiency is a rare type of EDS, defined as classical-like EDS (clEDS), since it phenotypically resembles the classical form of EDS, though lacking atrophic scarring. Although most patients display a well-defined phenotype, the diagnosis of TNX-deficiency is often delayed or overlooked. Here, we described an additional patient with clEDS due to a homozygous null-mutation in the TNXB gene. A review of the literature was performed, summarizing the most important and...

Carotid Artery Tortuosity Is Associated with Connective Tissue Diseases [EXTRACRANIAL VASCULAR]
BACKGROUND AND PURPOSE: There is a general assumption in the cerebrovascular literature that there is an association between carotid artery tortuosity and connective tissues disease; however, this has not been firmly established. The purpose of this study was to determine the prevalence of carotid artery tortuosity in patients with connective tissue diseases relative to matched controls. MATERIALS AND METHODS: Patients with previous CTA or MRA and a diagnosis of connective tissue diseases were identified and compared with a cohort of age-matched controls. Radiologists blinded to the diagnosis reviewed the images and evalu...

Symptomatic Joint Hypermobility: The Hypermobile Type of Ehlers-Danlos Syndrome and the Hypermobility Spectrum Disorders.
Abstract Joint hypermobility may be syndromic or nonsyndromic, asymptomatic or symptomatic. However, asymptomatic joint hypermobility can cause repetitive use injury, alter biomechanics, or become symptomatic later in life. Symptomatic joint hypermobility can result from soft tissue injury or muscular strain caused by muscular imbalance. Treatment is straightforward once joint hypermobility is recognized. Generalized joint hypermobility can be assessed using a standardized in-office examination. Generalized joint hypermobility may also be a feature of a heritable connective tissue disorder with other systemic find...

EP.133Biallelic mutations in Tenascin X, TNXB cause slowly progressive asymmetric myopathy with mild joint dislocations and connective tissue alterations
We describe a 46-year-old woman born to non-consanguineous healthy French parents, who reported slowly progressive lower limbs weakness since 28 years. She had difficulties in squatting, getting up from a chair, and, from 35 years, climbing stairs. She also reported myalgias, peripheral vascular disease in hands, joint hypermobility, multiples sprains, dislocation of the 5th finger, conjunctival hemorrhages, and colon perforation during a colonoscopy.
