RESUMEN
Mitochondrial dysfunction can be associated with a range of clinical manifestations. Here, we report a family with a complex phenotype including combinations of connective tissue, neurological, and metabolic symptoms that were passed on to all surviving children. Analysis of the maternally inherited mtDNA revealed a novel genotype encompassing the haplogroup J - defining mitochondrial DNA (mtDNA) ND5 m.13708G>A (A458T) variant arising on the mtDNA haplogroup H7A background, an extremely rare combination. Analysis of transmitochondrial cybrids with the 13708A-H7 mtDNA revealed a lower mitochondrial respiration, increased reactive oxygen species production (mROS), and dysregulation of connective tissue gene expression. The mitochondrial dysfunction was exacerbated by histamine, explaining why all eight surviving children inherited the dysfunctional histidine decarboxylase allele (W327X) from the father. Thus, certain combinations of common mtDNA variants can cause mitochondrial dysfunction, mitochondrial dysfunction can affect extracellular matrix gene expression, and histamine-activated mROS production can augment the severity of mitochondrial dysfunction. Most important, we have identified a previously unreported genetic cause of mitochondrial disorder arising from the incompatibility of common, nonpathogenic mtDNA variants.

Mast cell activation syndrome (MCAS) is a term applied to several clinical entities that have gained increased attention from patients and medical providers. Although several descriptive publications about MCAS exist, there are many gaps in knowledge, resulting in confusion about this clinical syndrome. Whether MCAS is a primary syndrome or exists as a constellation of symptoms in the context of known inflammatory, allergic, or clonal disorders associated with systemic mast cell activation is not well understood. More importantly, the underlying mechanisms and pathways that lead to mast cell activation in MCAS patients remain to be elucidated. Here we summarize the known literature, identify gaps in knowledge, and highlight research needs. Covered topics include contextualization of MCAS and MCAS-like endotypes and related diagnostic evaluations; mechanistic research; management of typical and refractory symptoms; and MCAS-specific education for patients and health care providers.

Craniocervical instability (CCI) is increasingly recognized in hereditary disorders of connective tissue and in some patients following suboccipital decompression for Chiari malformation (CMI) or low-lying cerebellar tonsils (LLCT). CCI is characterized by severe headache and neck pain, cervical medullary syndrome, lower cranial nerve deficits, myelopathy, and radiological metrics, for which occipital cervical fusion (OCF) has been advocated. We conducted a retrospective analysis of patients with CCI and Ehlers-Danlos syndrome (EDS) to determine whether the surgical outcomes supported the criteria by which patients were selected for OCF. Fifty-three consecutive subjects diagnosed with EDS, who presented with severe head and neck pain, lower cranial nerve deficits, cervical medullary syndrome, myelopathy, and radiologic findings of CCI, underwent open reduction, stabilization, and OCF. Thirty-two of these patients underwent suboccipital decompression for obstruction of cerebral spinal fluid flow. Questionnaire data and clinical findings were abstracted by a research nurse. Follow-up questionnaires were administered at 5-28 months (mean 15.1). The study group demonstrated significant improvement in headache and neck pain (p < 0.001), decreased use of pain medication (p < 0.0001), and improved Karnofsky Performance Status score (p < 0.001). Statistically significant improvement was also demonstrated for nausea, syncope (p < 0.001), speech difficulties, concentration, vertigo, dizziness, numbness, arm weakness, and fatigue (p = 0.001). The mental fatigue score and orthostatic grading score were improved (p < 0.01). There was no difference in pain improvement between patients with CMI/LLCT and those without. This outcomes analysis of patients with disabling CCI in the setting of EDS demonstrated significant benefits of OCF. The results support the reasonableness of the selection criteria for OCF. We advocate for a multi-center, prospective clinical trial of OCF in this population.

The Ehlers-Danlos syndromes (EDS), a group of uncommon connective tissue disorders, are, paradoxically, an increasingly common referral to genetics specialists. Of the 13 types of EDS, the most common is hypermobile EDS (hEDS), which lacks a known genetic etiology and for which diagnosis is achieved via a robust set of clinical criteria. While previous investigations have characterized many clinical aspects of EDS as a syndrome and patients' lived experiences, a gap in the literature exists regarding clinicians' experience caring for these individuals. This study sought to understand the effects of hEDS patient referrals from genetic counselors' perspectives. To capture these novel views and values, we conducted semi-structured interviews with 15 participants who were members of the National Society of Genetic Counselors (NSGC) and had experience working with the hEDS patient population. Interview questions explored the frequency of hEDS referrals in their clinic, investigated their roles and responsibilities as genetic counselors when working with this population, analyzed their workflow for this indication, assessed the impacts on their professional satisfaction, and explored potential options for improving workflow and care for the hEDS patient population. Reflexive thematic analysis yielded four themes: (1) Referrals for hEDS have generally increased over time and many institutions have implemented new policies to control this influx, (2) genetic counselors' primary roles include education and addressing psychosocial matters for this population, (3) genetic counselors feel both rewarded and challenged by these referrals, and (4) genetic counselors call for more education and training on hEDS for all healthcare specialties. Our findings provide a better understanding of the goals of the hEDS patient referrals to genetics specialists and the opportunities and challenges those referrals present. Genetic counselors have specific training and skills in psychosocial counseling and communication, in some ways making them ideal care providers for this population. However, they are simultaneously a scarce resource and the complex medical issues presented by many patients with hEDS make multidisciplinary management essential. We conclude with potential avenues for improving interactions with this population.
RESUMEN
Our study extends a cross-sectional dataset on the Ehlers-Danlos syndromes (EDS) assembled by the National Institute on Aging (NIA), under a protocol entitled Clinical and Molecular Manifestations of Heritable Disorders of Connective Tissue. We were successful in contacting 171 of the original 252 participants with EDS. Our study cohort included 91 participants who completed at least one of the following surveys: Brief Pain Inventory (BPI), Pittsburgh Sleep Quality Index (PSQI), Multidimensional Fatigue Inventory (MFI-20), and Short Form (SF-36) Health Survey, at both baseline and follow-up. Follow-up surveys occurred a median of 11.6 years after the baseline survey. We used mixed effects linear regression models to examine the change in scores for multiple indices reported by participants. There were small mean changes reflected in our estimates for the EDS population as a whole. There was wide heterogeneity between reported individual experiences, with some participants markedly improved and some dramatically worse. Men had a greater increase in mean pain severity over time than women. This is the first study to report a decade of longitudinal data in EDS.

Persons with the Ehlers-Danlos syndromes (EDS) report a wide range of respiratory symptoms, most commonly shortness of breath, exercise limitation, and cough. Also reported are noisy breathing attributed to asthma, difficulty with deep inhalation, and inspiratory thoracic pain. The literature consists of case reports and small cross-sectional and cohort studies. One case-control study estimated twofold to threefold greater respiratory disease burden among persons with EDS as compared to controls. The differential diagnosis for symptoms is broad. Structural alterations include pectus deformities, scoliosis, recurrent rib subluxations, and tracheobronchomalacia, associated with varying degrees of physiologic impairment. Those with vascular EDS have an increased risk of pneumothorax, intrapulmonary bleeding, cysts, and nonmalignant fibrous nodules. Functional aerodigestive manifestations such as inducible laryngeal obstruction may be misdiagnosed as asthma, with gastro-esophageal dysmotility and reflux as common contributing factors. Inflammatory manifestations include costochondritis, bronchiectasis, and localized respiratory allergic and nonallergic mast cell activation. Cranio-cervical instability can dysregulate respiratory control pathways. There is a need for careful phenotyping using standardized clinical tools and patient-reported outcomes and continuing collaboration with aerodigestive specialists including otolaryngologists and gastroenterologists. Also needed is further evaluation of respiratory symptoms in persons with hypermobility spectrum disorders. Personalized monitoring strategies are invaluable for interpretation and long-term management of respiratory symptoms.

We previously reported increased pain and gastrointestinal (GI) medication prescription claims among persons with Ehlers-Danlos syndromes (EDS) and peripubertal increase in opioid and anti-emetic claims among women with EDS. Herein, we hypothesized a higher proportion of respiratory and co-occurring respiratory and GI medication prescription claims among persons with EDS compared to their matched controls with increases among peripubertal women with EDS. We compared the proportions of respiratory and co-occurring respiratory and GI medication prescription claims among persons with EDS (aged 5-62) against their age-, sex-, state of residence-, and earliest claim date-matched controls using 10 years of private prescription claims data. Prescription claims among persons with EDS versus matched controls were increased for eight medication classes (p < .0001): intranasal/inhaled corticosteroids (ICS) (30.8% vs. 19.0%), oral steroids (30.0% vs. 16.5%), H1-antihistamines (26.2% vs. 12.2%), short-acting beta agonists (22.7% vs. 11.6%), decongestants (21.6% vs. 15.9%), leukotriene modifiers (8.9% vs. 3.6%), ICS/long-acting beta agonists (5.7% vs. 2.9%), muscarinic antagonists (2.5% vs. 0.9%), and co-occurring prescriptions (29% vs. 10%). Our results suggest a critical time window for peripubertal intervention and research and a need to focus on the pathogenesis and clinical evaluation of EDS-specific respiratory and aerodigestive disorders.

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 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. We describe the initial outcomes of the first four EDS ECHO programs, each comprising nine sessions. Participants reported increased levels of knowledge and confidence in providing care (93% and 95%, respectively) and an increase in referral network participation (65%). Additionally, 80% reported that their interest in EDS and HSD increased; 57% reporting a great increase. Also, 59% reported a decrease in feeling overwhelmed by EDS and HSD, and nearly half reported a decrease in their level of frustration because of participating in EDS ECHO. Clinicians participating in EDS ECHO programs know more, have more confidence in their ability to provide care, and feel energized by their participation.

Patients with hypermobile Ehlers-Danlos syndrome, an hereditary disorder of the connective tissue, often face a long and difficult diagnostic odyssey in pursuit of a name for their condition. Clinicians may dismiss subjective symptoms of chronic pain, thus prolonging patients' odysseys and worsening their care and satisfaction and creating antagonisms in the patient-provider relationship. A greater understanding of patient experiences is necessary in order to decrease burdens of this relationship and to improve care. To that end, we conducted 22 in-depth, semistructured interviews with individuals who had undergone this diagnostic odyssey. We focused on the impact that the odyssey had on their lives, both inside and outside the clinic. Through narrative analysis, we found a sort of "hero's journey" in the description of their cases, highlighting issues of uncertainty and integration as well as honoring their struggles. Interviewees had encountered difficulties in working with clinicians, in multiplying symptoms, and in negative psychosocial consequences. Attention to patients' lived experience may help to build empathy and understanding for the difficult and complex clinical situation presented by Ehlers-Danlos syndrome. Using the hero's journey as a lens onto this experience allows for a more patient-centered approach to this understanding and has potential value for comprehension of other complex diseases and invisible illnesses.

AEBP1 encodes the aortic carboxypeptidase-like protein (ACLP) that associates with collagens in the extracellular matrix (ECM) and has several roles in development, tissue repair, and fibrosis. ACLP is expressed in bone, the vasculature, and dermal tissues and is involved in fibroblast proliferation and mesenchymal stem cell differentiation into collagen-producing cells. Aebp1-/- mice have abnormal, delayed wound repair correlating with defects in fibroblast proliferation. In this study, we describe four individuals from three unrelated families that presented with a unique constellation of clinical findings including joint laxity, redundant and hyperextensible skin, poor wound healing with abnormal scarring, osteoporosis, and other features reminiscent of Ehlers-Danlos syndrome (EDS). Analysis of skin biopsies revealed decreased dermal collagen with abnormal collagen fibrils that were ragged in appearance. Exome sequencing revealed compound heterozygous variants in AEBP1 (c.1470delC [p.Asn490_Met495delins(40)] and c.1743C>A [p.Cys581∗]) in the first individual, a homozygous variant (c.1320_1326del [p.Arg440Serfs∗3]) in the second individual, and a homozygous splice site variant (c.1630+1G>A) in two siblings from the third family. We show that ACLP enhances collagen polymerization and binds to several fibrillar collagens via its discoidin domain. These studies support the conclusion that bi-allelic pathogenic variants in AEBP1 are the cause of this autosomal-recessive EDS subtype.

Victor Almon McKusick (VAM) is widely recognized as the father of the field of medical genetics. He established one of the first medical genetics clinics in the United States at Johns Hopkins in 1957 and developed a robust training program with the tripartite mission of education, research, and clinical care. Thousands of clinicians and scientists were educated over the years through the Short Course in Medical and Molecular Genetics, which VAM founded with Dr. Thomas Roderick in 1960. His Online Mendelian Inheritance in Man (OMIM), a catalog of human genes and genetic disorders, serves as the authoritative reference for geneticists around the globe. Throughout his career he was an advocate for mapping the human genome. He collaborated with Dr. Frank Ruddle in founding the International Human Gene Mapping Workshops in the early 70's and was an avid proponent of the Human Genome Project. He was the founding President of the Human Genome Organization and a founding editor of the journal Genomics. His prodigious contributions to the field of medical genetics were recognized by multiple honors, culminating with the Japan Prize in 2008.

Atlanto-axial instability (AAI) is common in the connective tissue disorders, such as rheumatoid arthritis, and increasingly recognized in the heritable disorders of Stickler, Loeys-Dietz, Marfan, Morquio, and Ehlers-Danlos (EDS) syndromes, where it typically presents as a rotary subluxation due to incompetence of the alar ligament. This retrospective, IRB-approved study examines 20 subjects with Fielding type 1 rotary subluxation, characterized by anterior subluxation of the facet on one side, with a normal atlanto-dental interval. Subjects diagnosed with a heritable connective tissue disorder, and AAI had failed non-operative treatment and presented with severe headache, neck pain, and characteristic neurological findings. Subjects underwent a modified Goel-Harms posterior C1-C2 screw fixation and fusion without complication. At 15 months, two subjects underwent reoperation following a fall (one) and occipito-atlantal instability (one). Patients reported improvement in the frequency or severity of neck pain (P < 0.001), numbness in the hands and lower extremities (P = 0.001), headaches, pre-syncope, and lightheadedness (all P < 0.01), vertigo and arm weakness (both P = 0.01), and syncope, nausea, joint pain, and exercise tolerance (all P < 0.05). The diagnosis of Fielding type 1 AAI requires directed investigation with dynamic imaging. Alignment and stabilization is associated with improvement of pain, syncopal and near-syncopal episodes, sensorimotor function, and exercise tolerance.

BACKGROUND: Alström syndrome (AS) is a rare autosomal recessive ciliopathy with a wide spectrum of clinical features, including cone-rod retinal dystrophy, neuronal deafness, severe insulin resistance and major organ failure. The characteristics of renal disease in the syndrome have not been systematically described. The aim of this study is to define the onset and progression of renal disease in AS. METHOD: Prospective observational cohort study. SETTING AND PARTICIPANTS: Thirty-two adult subjects from a national specialist clinic in UK and 86 subjects from an international AS registry were studied. OUTCOMES: First, an international registry cross-sectional study across all age groups to determine change in kidney function was performed. Secondly, a detailed assessment was carried out of adult AS patients with serial follow-up to determine incidence, aetiology and progression of renal disease. ANALYTICAL APPROACH: Generalized estimating equations were used to evaluate the relationship between age and estimated glomerular filtration rate (eGFR). Associations between patient factors and eGFR levels were then assessed in the adult AS cohort. RESULTS: The international registry study of the renal function of 118 subjects with AS (median age 21 years) showed a rapid decline with age, at an average of -16.7 and -10.9 mL/min/1.73 m2 per decade in males and females, respectively. In a UK national cohort of 32 patients with AS (median age 22 years), 20/32 (63%) had chronic kidney disease (CKD) Stage 3 or above based on eGFR <60 mL/min/1.73 m2 or evidence of albuminuria. Hyperuricaemia was noted in 25/32 (79%). Structural abnormalities such as nephrocalcinosis without hypercalcaemia and cysts were observed in 20/32 (63%) subjects. Lower urinary tract symptoms were frequent in 17/19 (70%) of AS patients. Histological evidence showed mixed tubulo-interstitial and glomerular disease. CONCLUSIONS: This is the first study to demonstrate that renal disease is the hallmark of AS, which starts early and progresses with age, leading to a high prevalence of advanced CKD at young age. AS should be considered in the differential diagnosis of rare genetic renal diseases.

Against the backdrop of increased opioid prescribing in the United States and the associated high rate of side effects, dependence, and addiction, our study examined how opioids and other medications are being used among persons with Ehlers-Danlos syndrome (EDS). EDS is a set of heritable connective tissue disorders with high symptom burden, including chronic pain. Prescription medication use among persons with EDS was compared to a cohort of matched controls using 10 years of administrative claims data from a large database of privately insured patients (2005-2014). Our dataset included 4,294 persons with EDS, ages 5-62 years old. In both adults and children, we found that the percentage of persons with a prescription drug claim was higher in the EDS cohort for all prescription drug classes examined. Among children, opioid use was double in the EDS cohort compared to the control group (27.5% vs. 13.5%); in adults, it was nearly double in EDS patients (62% vs. 34.1%). Among persons who were prescribed opioids, those with EDS had higher cumulative dosages over a 2-year time period versus controls. Our study aids in understanding opioid and prescription drug use patterns in a vulnerable population with high symptom burden and chronic pain that is often severe.

We describe a data repository on heritable disorders of connective tissue (HDCT) assembled by the National Institutes of Health's National Institute on Aging (NIA) Intramural Research Program between 2001 and 2013. Participants included affected persons with a wide range of heritable connective tissue phenotypes, and unaffected family members. Elements include comprehensive history and physical examination, standardized laboratory data, physiologic measures and imaging, standardized patient-reported outcome measures, and an extensive linked biorepository. The NIA made a commitment to make the repository available to extramural investigators and deposited samples at Coriell Tissue Repository (N = 126) and GenTAC registry (N = 132). The clinical dataset was transferred to Penn State University College of Medicine Clinical and Translational Science Institute in 2016, and data elements inventoried. The consented cohort of 1,009 participants averaged 39 ± 18 years (mean ± SD, range 2-95) at consent; gender distribution is 71% F and 83% self-report Caucasian ethnicity. Diagnostic categories include Ehlers-Danlos syndrome (classical N = 50, hypermobile N = 99, vascular N = 101, rare types and unclassified N = 178), Marfan syndrome (N = 33), Stickler syndrome (N = 60), fibromuscular dysplasia (N = 135), Other HDCT (N = 72). Unaffected family members (N = 218) contributed DNA for the molecular archive only. We aim to develop further discrete data from unstructured elements, analyze multisymptom HDCT manifestations, encourage data use by other researchers and thereby better understand the complexity of these high-morbidity conditions and their multifaceted effects on affected persons.

Hypermobile Ehlers-Danlos syndrome (hEDS) is a hereditary disorder of connective tissue, often presenting with complex symptoms can include chronic pain, fatigue, and dysautonomia. Factors influencing functional disability in the pediatric hEDS population are incompletely studied. This study's aims were to assess factors that affect quality of life in children and adolescents with hEDS. Individuals with hEDS between the ages 12-20 years and matched parents were recruited through retrospective chart review at two genetics clinics. Participants completed a questionnaire that included the Pediatric Quality of Life Inventory (PedsQL™), PedsQL Multidimentional Fatigue Scale, Functional Disability Inventory, Pain-Frequency-Severity-Duration Scale, the Brief Illness Perception Questionnaire, measures of anxiety and depression, and helpful interventions. Survey responses were completed for 47 children and adolescents with hEDS/hypermobility spectrum disorder (81% female, mean age 16 years), some by the affected individual, some by their parent, and some by both. Clinical data derived from chart review were compared statistically to survey responses. All outcomes correlated moderately to strongly with each other. Using multiple regression, general fatigue and pain scores were the best predictors of the PedsQL total score. Additionally, presence of any psychiatric diagnosis was correlated with a lower PedsQL score. Current management guidelines recommend early intervention to prevent disability from deconditioning; these results may help identify target interventions in this vulnerable population.

The objective of this study was to explore the factors contributing to quality of life in pediatric patients with non-vascular Ehlers-Danlos syndromes (EDS). Data were analyzed on 41 children with a diagnosis of non-vascular EDS from the de-identified data available from the National Institute on Aging (NIA) study of heritable disorders of connective tissue. Children under age 19 years were seen as part of a long-term evaluation project from 2003 to 2013 on a larger natural history of patients with heritable disorders of connective tissue. Data collected included medical history, physical examination findings, diagnostic study results, and responses on validated questionnaires. We reviewed a sub-cohort of children with a diagnosis of non-vascular EDS and explored pain severity and interference via the Brief Pain Inventory, and sleep quality via the Pittsburgh Sleep Quality Index. Pain severity had a strong correlation with pain interference, and both were similar to other disorders that include chronic pain reported in the literature. Sleep quality did not correlate with pain severity or interference, but all patients had poor sleep quality in comparison to historical controls. We conclude that pain and sleep are significant issues in the pediatric non-vascular EDS population, and future research may be directed toward these issues.

Since 1998, two developments have led to concerns that the EDS nosology needs to be substantially revised. The first development was the clinical and molecular characterization of several new EDS variants, which substantially broadened the molecular basis underlying EDS. The second was the growing concern, in the absence of genetic diagnosis, that the hypermobile type of EDS had an expanded phenotype, may be genetically heterogeneous, and that the diagnostic criteria currently in use were inadequate. Furthermore, there is a dire need for the development of guidelines for management for each type of EDS to allow both the specialist and the generalist to care for affected individuals and their families. We have been meeting together as an international consortium over the past 2 years to establish these new criteria and management and care guidelines © 2017 Wiley Periodicals, Inc.
