RESUMO

BACKGROUND: Ehlers-Danlos syndrome (EDS) is a hereditary disorder that affects the connective tissue and collagen structures in the body characterised by joint hypermobility, skin hyperextensibility and tissue fragility. OBJECTIVE: The aim was to investigate temporomandibular disorders (TMD), bite force, teeth in occlusal contact and osseous changes of the temporomandibular joints (TMJs) in 26 patients with hypermobile EDS (hEDS), differentiated by a genetic test, compared to 39 healthy controls. METHODS: Clinical examination according to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), radiological examinations of the TMJs by cone-beam-computed tomographic (CBCT) scans, registration of bite force and teeth in occlusal contact was performed. Statistical analyses included Fisher's Exact Test, multiple logistic and linear regression models adjusted for age, gender and Body Mass Index (BMI). RESULTS: Single symptoms and signs of TMD occurred significantly more often in hEDS (p = .002; p = .001; p = .003; p = <.0001; p = .012) and maximum mouth opening was significantly smaller in hEDS compared to controls (p = <.0001). The DC/TMD diagnosis myalgia, myofascial pain with referral, arthralgia, headache attributed to TMD, disc displacement disorders and degenerative joint disease occurred significantly more often in hEDS compared to controls (p = .000; p = .008; p = .003; p = .000; p = <.0001; p = .010, respectively). No significant differences were found in bite force and in teeth in occlusal contact between the groups (p > .05). On CBCT of the TMJs, subcortical sclerosis occurred significantly more often in hEDS compared to controls (p = .005). CONCLUSION: Symptoms and signs of TMD and osseous changes of the TMJs occurred significantly more often in hEDS. Bite force and teeth in occlusal contact were comparable to controls.

RESUMO

OBJECTIVE: The aim: Determination of anatomical and topographical relationships of the eyeball anterior segment structures to assess possible glaucoma development risk factors in SED patients with myopic refraction. PATIENTS AND METHODS: Materials and methods: Patients, aged from 10 to 34, have been examined since 2009. All the patients have undergone required medic and genetic examination as well as generally accepted ophthalmological one. Ultrasound biomicroscopy (UBM) has been performed using the VuMax II apparatus (Sonomed, USA) with a sensor frequency of 50 MHz. RESULTS: Results: Biomicroscopy found no symptoms such as pigment dispersion on the iris stroma, in the chamber anterior angle, iris transillumination and "Krukenberg's Spindle", which are characteristic for the ultrasound picture in pigment dispersion syndrome. CONCLUSION: Conclusions: 1. Clinical and functional study with the eyeballs mandatory ultrasound biomicroscopy have revealed functional space limitations for the structures of the iridociliary zone in patients with myopic type of eye structure in SED. 2. Detected congenital changes in the anterior segment structures (iridociliary cystic formations and residual mesodermal tissue) can lead to the emergence of intraocular blocks. 3. The research has identified conducive anatomical and topographic changes, which are likely to induce pigment dispersion syndrome or lead to the development of pigmentary glaucoma. 4. In our opinion, the UBM role in the early diagnosing and monitoring patients with SED syndrome is quite significant in terms of assessing the stability or dynamics of the changes received and possible complications. Ultrasound biomicroscopic scanning should be added to the list of necessary early diagnostic examinations to determine the markers and features of structures in SED.

RESUMO

Dysautonomia is a recognized manifestation in patients with joint hypermobility (JH) disorders. Symptoms can be highly debilitating and commonly include physical deconditioning and poor aerobic fitness. In this study, the prevalence of dysautonomia, range of associated symptoms, patient-reported physical activity levels, and echocardiographic features were assessed retrospectively in a cohort of 144 patients (94% female) with hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobility spectrum disorder (HSD). Echocardiographic parameters of left ventricular size and function were compared between patients with and without dysautonomia as well as to reported values from healthy controls. Dysautonomia was identified in 65% of female and 44% of male subjects and was associated with a high burden of symptomatology, most commonly exercise intolerance (78%). Exercise capacity was limited by dysautonomia, often postural symptoms, in half of all patients. We observed a reduction in physical activity following the onset or significant flare of hEDS/HSD, most strikingly noting the proportion of dysautonomic patients with sedentary lifestyle, which increased from 44% to 85%. JH-related dysautonomia was associated with smaller cardiac chamber sizes, consistent with the previous reports in positional orthostatic tachycardia syndrome. Dysautonomia is prevalent in patients with hEDS/HSD, and exercise intolerance is a key feature and leads to drastic decline in physical activity. Unfavorable cardiac geometry may underlie dysautonomia symptoms and may be due to cardiac atrophy in the setting of aerobic deconditioning.

RESUMO

OBJECTIVES: To describe CT features of lung involvement in patients with vascular Ehlers-Danlos syndrome (vEDS), a rare genetic condition caused by pathogenic variants within the COL3A1 gene, characterized by recurrent arterial, digestive, and pulmonary events. MATERIAL AND METHODS: All consecutive vEDS patients referred to the national tertiary referral center for vEDS, between 2004 and 2016, were included. Chest CT scans obtained during the initial vascular work-up were reviewed retrospectively by two chest radiologists for lung involvement. Five surgical samples underwent histologic examination. RESULTS: Among 136 enrolled patients (83 women, 53 men; mean age 37 years) with molecularly confirmed vEDS, 24 (17.6%) had a history of respiratory events: 17 with pneumothorax, 4 with hemothorax, and 3 with hemoptysis that required thoracic surgery in 11. CT scans detected lung parenchymal abnormalities in 78 (57.3%) patients: emphysema (mostly centrilobular and paraseptal) in 44 (32.3%), comparable for smokers and non-smokers; clusters of calcified small pulmonary nodules in 9 (6.6%); and cavitated nodules in 4 (2.9%). Histologic examination of surgical samples found arterial abnormalities, emphysema with alveolar ruptures in 3, accompanied by diffuse hemorrhage and increased hemosiderin resorption. CONCLUSION: In vEDS patients, identification of lung parenchymal abnormalities is common on CT. The most frequently observed CT finding was emphysema suggesting alveolar wall rupture which might facilitate the diagnostic screening of the disease in asymptomatic carriers of a genetic COL3A1 gene mutation. The prognostic value and evolution of these parenchymal abnormalities remain to be evaluated. KEY POINTS: • Patients with vEDS can have lung parenchymal changes on top of or next to thoracal vascular abnormalities and that these changes can be present in asymptomatic cases. • The presence of these parenchymal changes is associated with a slightly higher incidence of respiratory events (although not statistically significant). • Identification of the described CT pattern by radiologists and chest physicians may facilitate diagnostic screening.

RESUMO

PURPOSE: To report endovascular repair of postdissection thoracoabdominal aortic aneurysm (TAAA) in 2 patients with vascular Ehlers-Danlos syndrome (vEDS). CASE REPORTS: Case 1. A 56-year-old vEDS male patient with a 50-mm type III TAAA [history of aortic root repair, hemiarch replacement, and thoracic endovascular aortic repair (TEVAR) for acute type A aortic dissection (TAAD) 7 years ago] was treated by a 2-stage procedure; first, cervical debranching of the left subclavian artery and second TEVAR and t-branch. The postoperative course was uneventful. Follow-up computed tomography angiography (CTA) 3.5 years postoperatively demonstrated aortic remodeling with patency of targeted visceral vessels and no endoleak. Case 2. A 47-year-old vEDS male patient presented with a TAAA (diameter of 67 mm). The patient had a history of aortic valve and arch replacement with elephant trunk for acute TAAD, and consequently a TEVAR and candy-plug procedure after a ruptured false lumen (FL) aneurysm of the descending thoracic aorta. He also had a surgical repair by an aorto-bi-iliac graft. Two years later, CTA demonstrated aneurysmal FL dilatation distally to the candy-plug and he was treated with fenestrated EVAR (F-EVAR). CONCLUSION: Endovascular repair of postdissection TAAA was feasible and safe with good short-term outcome in 2 patients with vEDS.

RESUMO

OBJECTIVE: While rare variants in the COL5A1 gene have been associated with classical Ehlers-Danlos syndrome and rarely with arterial dissections, recurrent variants in COL5A1 underlying a systemic arteriopathy have not been described. Monogenic forms of multifocal fibromuscular dysplasia (mFMD) have not been previously defined. Approach and Results: We studied 4 independent probands with the COL5A1 pathogenic variant c.1540G>A, p.(Gly514Ser) who presented with arterial aneurysms, dissections, tortuosity, and mFMD affecting multiple arteries. Arterial medial fibroplasia and smooth muscle cell disorganization were confirmed histologically. The COL5A1 c.1540G>A variant is predicted to be pathogenic in silico and absent in gnomAD. The c.1540G>A variant is on a shared 160.1 kb haplotype with 0.4% frequency in Europeans. Furthermore, exome sequencing data from a cohort of 264 individuals with mFMD were examined for COL5A1 variants. In this mFMD cohort, COL5A1 c.1540G>A and 6 additional relatively rare COL5A1 variants predicted to be deleterious in silico were identified and were associated with arterial dissections (P=0.005). CONCLUSIONS: COL5A1 c.1540G>A is the first recurring variant recognized to be associated with arterial dissections and mFMD. This variant presents with a phenotype reminiscent of vascular Ehlers-Danlos syndrome. A shared haplotype among probands supports the existence of a common founder. Relatively rare COL5A1 genetic variants predicted to be deleterious by in silico analysis were identified in ≈2.7% of mFMD cases, and as they were enriched in patients with arterial dissections, may act as disease modifiers. Molecular testing for COL5A1 should be considered in patients with a phenotype overlapping with vascular Ehlers-Danlos syndrome and mFMD.

RESUMO

OBJECTIVES: Loeys-Dietz syndrome (LDS) and vascular Ehlers-Danlos Syndrome (vEDS) are genetically heterogeneous heritable disorders of connective tissue. Both are multi-system disorders with dominant vascular pathology and associated gastrointestinal manifestations. AIM: To summarize the abdominal manifestations found in these two disorders in a cohort of patients seen at Mayo Clinic during a period of 25 years. METHODS: Data were collected via the advanced cohort explorer (ACE) of Mayo Clinic records from 1994 to 2018 in patients with vEDS or LDS confirmed by genetic testing and/or medical genetics consultation. We extracted information concerning gastrointestinal symptoms, abdominal hernias, and vascular manifestations or complications. RESULTS: We identified and reviewed records of 68 vEDS and 13 LDS patients. Patients were similar in age at diagnosis and gender distribution. Gastrointestinal symptoms were frequently reported in both disorders and largely similar, although altered bowel function was more prevalent in LDS patients. Hernias were present in similar proportions of patients with vEDS and LDS; however, ventral hernias were more frequent and more likely to be postoperative in vEDS than LDS. LDS patients had more arterial aneurysms overall (76.9% LDS vs. 58% vEDS, p = 0.02) and a higher proportion required arterial repair (69.2% LDS vs. 32.7% vEDS S, p = 0.03). Co-morbidities of autonomic dysfunction, psychopathology (most commonly anxiety, depression, adjustment disorder), and allergy were more prevalent in LDS than vEDS. CONCLUSION: Patients with vEDS and LDS had a propensity for gastrointestinal symptoms, abdominal hernias, and aneurysm formation, but repair for arterial rupture was more prevalent in LDS than EDS.

RESUMO

Ehlers-Danlos syndrome is a real diagnosis that is erroneously used to explain multiple fractures in suspected child abuse. This paper reviews the clinical and molecular diagnostic criteria for Ehlers-Danlos syndrome. This knowledge can help prevent misdiagnosis and support clinicians when evaluating infants and young children with multiple fractures.

RESUMO

BACKGROUND: Patients with vascular Ehlers-Danlos syndrome (EDS) occasionally suffer from arterial dissection. Eagle syndrome, which is caused by an elongated styloid process and also causes arterial dissection, is difficult to diagnose and could sometimes be overlooked. Little is known of the coexistence of these two diseases, and treatment strategy is not established. Here, we present a case of bilateral internal carotid artery (ICA) dissection due to Eagle syndrome in a patient with vascular EDS. CASE PRESENTATION: A 30-year-old man was admitted to our hospital because of sudden onset of mild sensory disturbance in his left limbs. He had a history of Ehlers-Danlos syndrome (EDS) and also had left cervical internal carotid artery (ICA) dissection 3 years before. Diffusion-weighted imaging showed acute cerebral infarcts in the right hemisphere. Cervical computed tomography angiography (CTA) revealed the right ICA narrowing at the cervical portion in addition to the previous left cervical ICA dissection. Cervical magnetic resonance imaging (MRI) revealed double-lumen and intramural hematoma at the narrowing portion of the right cervical ICA, which indicates arterial dissection. CT also revealed bilateral elongated styloid processes which are close to each side of cervical ICA. We diagnosed him as bilateral ICA dissection due to bilateral Eagle syndrome. Considering vascular complications due to vascular EDS, we performed closer follow-up with transoral carotid ultrasonography (TOCU). In 4 months, his right ICA dissection gradually improved without stroke recurrence or deterioration of dissection. CONCLUSIONS: Since patients with vascular EDS easily develop arterial dissection, Eagle syndrome may be overlooked. Clinicians should consider Eagle syndrome in the case of vascular EDS with extracranial ICA dissection and close follow-up should be prioritized in cases of Eagle syndrome with vascular EDS.

RESUMO

OBJECTIVE: The objective of the study was to compare the acromiohumeral distance (AHD) between patients diagnosed with hypermobility type of the Ehlers-Danlos syndrome (hEDS) or hypermobility spectrum disorder (HSD) and healthy controls by evaluating the relative amount the tendon occupies in the subacromial area. Furthermore, the aim was to evaluate if there was a change in AHD with arm elevation within and between groups. METHODS: Twenty-nine female patients with hEDS/HSD (aged 34 ± 12.9 years) and 20 healthy controls (aged 33 ± 10.8 years) participated in the study. The supraspinatus tendon (SST) thickness and AHD were measured using ultrasound. The interplay between the SST and the AHD was expressed as the occupation ratio (OcAHD), calculated as the SST thickness as a percentage of AHD. The measures were performed in the resting position and in subsequently 45° and 60° of active arm elevation in the scapular plane. RESULTS: The main finding is that patients with hEDS/HSD have a larger subacromial space outlet compared with the controls when measured by ultrasound. Furthermore, in both groups, we found an increased OcAHD during active arm elevation compared with the resting position, which indicates that similar mechanisms occur for patients with hEDS/HSD and healthy controls. CONCLUSION: Patients with hEDS/HSD have a larger available subacromial space outlet compared with healthy individuals. OcAHD increased during active arm elevation compared with the resting position in both groups. This knowledge is important when designing rehabilitation exercise programs for shoulder instability patients with abnormal glenohumeral biomechanics.

RESUMO

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.

RESUMO

Kyphoscoliotic Ehlers-Danlos syndrome associated with FKBP14 (FKBP14-kEDS) is an ultrarare autosomal recessive disorder reported in less than 30 individuals so far. In its original description, emphasis was put on the mild muscle involvement. Further reports confirm that FKBP14-kEDS is distinguishable from primary muscle disorders by the lack of progressive muscle disease. We report a 15-year-old girl with FKBP14-kEDS as a result of the recurrent c.362dupC variant, who also showed severe involvement of the lower limb muscles. She never attained autonomous walking and presented significant lower limb weakness. Lower limb magnetic resonance imaging showed a pattern of multiple muscle involvement. Further musculoskeletal assessment revealed significant bone mass density reduction of the spine, unilateral congenital hip dysplasia, and occipitoatlantoaxial instability. This patient points out the existence of a wider phenotypic spectrum of FKBP14-kEDS to include early onset muscle disease.

RESUMO

OBJECTIVE: Vascular Ehlers-Danlos syndrome (vEDS) is associated with arterial ruptures due to a mutant gene encoding collagen type III (Col-III). To better understand the role of Col-III, we aimed at evaluating aortic stiffness and dynamic stiffening in vEDS mouse models, with either a quantitative (col3KO mice) or a qualitative Col-III defect (col3KI mice). MATERIALS AND METHODS: Abdominal aortic wall pulse wave velocities (PWV) in col3KO and col3KI mice were compared to their respective wild type (WT) littermates using a 15 MHz ultrafast ultrasonic transducer. A carotid catheter continuously monitored pressure changes due to phenylephrine injections. PWV1, generated at diastolic blood pressure (DBP), and PWV2, at systolic blood pressure (SBP) were recorded. Difference between PWV2 and PWV1 (Delta-PWV) normalized by the pulse pressure (PP), corresponding to the aortic stiffening over the cardiac cycle, were compared between mutant and WT mice, as well as the regression slope of PWV as a function of pressure. RESULTS: Delta-PWV/PP was lower in col3KO (p = 0.033) and col3KI mice (p < 0.001) vs. WT-mice regardless of the pressure level. The slope of PWV1 with DBP increase showed a lower arterial stiffness in mutant mice vs. controls in both models. This difference was amplified when evaluating stiffness at systolic blood pressure levels with PWV2. CONCLUSION: In both vEDS mouse models, aortic stiffening was reduced, mainly driven by a lower stiffness at systolic blood pressure. Defective Col-III may be responsible for this, as it is utilized when pressure rises. These pre-clinical data could explain vascular fragility observed in vEDS patients.

RESUMO

Ehlers-Danlos syndrome refers to a spectrum of connective tissue disorders typically caused by mutations in genes responsible for the synthesis of collagen. Patients with Ehlers-Danlos syndrome often exhibit hyperflexibility of joints, increased skin elasticity, and tissue fragility. Vascular Ehlers-Danlos (vEDS) is a subtype of Ehlers-Danlos syndrome with a predilection to involve blood vessels. As such, it often manifests as vascular aneurysms and vessel rupture leading to hemorrhage. There are few reports describing primary prevention of aneurysms in the setting of undiagnosed, suspected vEDS. We present a case of a 30-year-old woman who presents with a pulsatile neck mass found to have multiple arterial aneurysms on imaging, hyperflexibility, and characteristic facial features consistent with vEDS. As described in this case, management of a suspected connective tissue disorder is a multidisciplinary approach including vascular surgery, medical therapy, and genetic testing to confirm the diagnosis. We review literature regarding the care of patients with vascular Ehlers-Danlos as it might pertain to hospitalized patients.

RESUMO

Musculocontractural Ehlers-Danlos syndrome caused by mutations in CHST14 (mcEDS-CHST14) is a recently delineated disorder, characterized by craniofacial, skeletal, visceral, and ocular malformations; and progressive cutaneous, skeletal, vascular, and visceral fragility-related manifestations. Spinal lesions, though one of the most serious complications, have not been investigated systematically. In this study, we report detailed and comprehensive information about spinal lesions of 12 patients with a mean age at the first visit of 13.4 years. Eight patients (66.7%) had scoliosis with a Cobb angle ≥10°, including one with severe scoliosis with a Cobb angle ≥45°. Five patients (41.7%) had kyphosis at the thoracolumbar junction with a kyphotic angle ≥20°. Three patients (25%) developed severe thoracolumbar kyphosis with a kyphotic angle ≥50° accompanied by thoracic lordosis with a wedge-like vertebral deformity and anterior vertebral osteophyte at the thoracolumbar junction, and two of them underwent surgical correction: complicated by fistula formation in one and performed safely and effectively through two-staged operation in the other. Six patients (50.0%) had cervical kyphosis, all of whom except one had kyphosis ≥20° at the thoracolumbar level. Two patients (16.7%) had atlantoaxial subluxation, and 10 patients (83.3%) had cervical vertebral malformations. Patients with mcEDS-CHST14 are susceptible to develop scoliosis, thoracolumbar kyphosis, and cervical kyphosis; and are recommended to have regular surveillance including total spine radiology. The present findings also suggest the critical role of dermatan sulfate in the development and maintenance of the spine.

RESUMO

BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children. We describe the first case of successful surgical treatment in an infant with a high cervical kyphotic deformity in EDS. CASE PRESENTATION: A 15-month-old female with EDS presented with several months of regression in gross motor skills in all four extremities. Imaging demonstrated 45° of kyphosis from the C2-4 levels with spinal cord compression. Corrective surgery consisted of a C3 corpectomy and C2-4 anterior fusion with allograft block and anterior fixation with dual 2 × 2 hole craniofacial miniplates, supplemented by C2-4 posterior fusion using four craniofacial miniplates fixated to the lamina. Radiographs at 20 months post-surgery demonstrated solid fusion both anteriorly and posteriorly with maintenance of correction. CONCLUSIONS: Ehlers-Danlos syndrome may present in the pediatric population with congenital kyphosis from cervical deformity in addition to the more commonly seen thoracolumbar deformities.

RESUMO

Vascular Ehlers-Danlos syndrome (type IV) is an autosomal dominant disorder caused by heterozygous variants of COL3A1. We identified biallelic COL3A1 variants in two unrelated families. In a 3-year-old female with developmental delay the nonsense variant c.1282C>T, p.(Arg428*) was detected in combination the c.2057delC, p.(Pro686Leufs*105) frame shift variant. Both compound heterozygous variants were novel. This patient was born with bilateral clubfoot, joint laxity, and dysmorphic facial features. At the age of 2 years she developed an aneurysmal brain hemorrhage. Cerebral MRI showed a peculiar pattern of profound cerebral abnormalities including bilateral frontoparietal polymicrogyria of the cobblestone variant. In the second family, the two affected siblings were homozygous for the missense variant c.145C

RESUMO

We report the clinical, radiological, biochemical, muscle histology, and electron microscopic features of two members of a family with combined Ehlers-Danlos syndrome (EDS) [classic and vascular type] and progressive myopathy as the primary manifestation. A 35-year old lady presented with severe gluteal and thigh muscle pain and easy fatigability for 5 years. She developed weakness and wasting of pelvic and pectoral girdles and thighs for 3 years and severe neck flexor and truncal weakness for 6 months. She had a history of recurrent jaw dislocation, easy bruising with hyperpigmentation, hyperextensibility of joints, translucent skin, and papyraceous scars. She had high myopia with astigmatism. She had wasting of temporalis, masseters, sternocleidomastoids and trapezius. There was moderate weakness of temporalis, masseters, and facial muscles. Muscle power was Medical Research Council (MRC) grade 4 at shoulders and arms, and grade 3+ at pelvis and thighs. Serum homocysteine level was normal, and creatine kinase (CK) was 275 IU. Two dimensional echocardiogram (2D Echo) showed myxomatous degeneration of mitral valves. Electromyography (EMG) was suggestive of a myopathic pattern. Muscle magnetic resonance imaging (MR) revealed severe fatty infiltration of paraspinal muscles, gluteus maximus and medius, quadriceps, hamstrings, and gastrocnemius. Electron microscopy showed an occasional distorted fibril with mild increase in oxytalan fibers and variation in thickness of blood vessel basement membrane. Her 15-year old daughter had exertion-induced myalgias, right hemifacial hypoplasia, myopia, hyperextensible joints, hyperelastic skin, and neck muscle weakness. However, her CK and 2D Echo were normal. This report presents the rare combination of classic and vascular type of EDS primarily presenting as muscle weakness and associated with facial and trigeminal motor weakness.
