Chronic pain in the Ehlers–Danlos syndromes (EDS) is common and may be severe. According to one study, nearly 90% of patients report some form of chronic pain. Pain, which is often one of the first symptoms to occur, may be widespread or localized to one region such as an arm or a leg. Studies on treatment modalities are few and insufficient to guide management. The following is a discussion of the evidence regarding the underlying mechanisms of pain in EDS. The causes of pain in this condition are multifactorial and include joint subluxations and dislocations, previous surgery, muscle weakness, proprioceptive disorders, and vertebral instability. Affected persons may also present with generalized body pain, fatigue, headaches, gastrointestinal pain, temporomandibular joint pain, dysmenorrhea, and vulvodynia. Pain management strategies may be focused around treating the cause of the pain (e.g., dislocation of a joint, proprioceptive disorder) and minimizing the sensation of pain. Management strategies for chronic pain in EDS includes physical therapy, medications, as well as durable medical equipment such as cushions, compressive garments, and braces. The different modalities are discussed in this paper. © 2017 Wiley Periodicals, Inc.
Mast cell activation disease (MCAD) includes single organ disease such as asthma, urticaria, and gastroenteritis, as well as multiorgan system involvement such as mast cell activation syndrome and anaphylaxis. Reports link MCAD with hypermobile Ehlers-Danlos syndrome (hEDS), hypermobility spectrum disorder (HSD), and with primary immune deficiencies such as complement and immunoglobulin deficiencies (Ig Def). This study assesses the concurrence of these syndromes. We undertook a cohort analysis of patients seen in a community-based Allergy/Immunology clinic from 2015 to 2019. We searched for diagnostic codes for Ig Def disorders, hypermobility syndrome, hypermobile/Ehlers-Danlos syndrome, and MCADs. Of 974 patients with suspected MCAD, 449 (46%) had a diagnosis of MCAD; 496 (51%) of cases had a combination of at least two of hEDS/HSD, MCAD, and Ig Def. Ig Def was present in 417 (43%) of patients; 188 (19.3%) had hEDS/HSD with an Ig Def with or without MCAD and accounted for 45% of all the cases with Ig Def. Of 974 cases, 101 (10%) had hEDS/HSD and MCAD; 207 (21%) had Ig Def and MCAD; 7 (0.7%) had Ig Def and hEDS/HSD; and 181 (19%) had a combination of all three syndromes. Most patients (74%) with these comorbidities were female. The presence of MCAD and Ig Def should be explored in patients with hEDS/HSD. Identifying underlying contributors to recurrent/chronic inflammation and tissue injury is needed to tailor and personalize therapies. This, in turn, can reduce tissue damage, iatrogenic intervention, and optimize health outcomes.
Background Mast cells are closely associated with epithelium, serving as sentinels responsible for the recognition of tissue injury and coordination of the initial inflammatory response. Upon detection of the injured cell content, mast cells then tailor the release of preformed and newly produced chemical mediators to the detected challenge, via an array of pathogen receptors. In addition to immunoglobulin E receptor-triggered mast cell activation, commonly referred to as allergic or atopic disorders, non-immunoglobulin E receptor mediated mast cell activation follows engagement of toll-like receptors, immunoglobulin G receptors, and complement receptors. Upon containment of the extrinsic challenge, acute inflammation is downregulated, and repair of the injured tissue ensues. The mast cell compartments must return to a baseline steady state to remain tolerant towards self-antigens and harmless entities, including environmental conditions, to prevent unnecessary immune activation and chronic hypersensitivity disorders. Over the past 50 years, an increasing number of patients are experiencing episodes of aberrant mast cell activation, not associated with allergen-specific mast cell disease or systemic mastocytosis. This led to proposed diagnostic criteria of mast cell activation syndrome. Mast cell activation syndrome is a heterogeneous disorder, defined by a combination of (1) recurrent symptoms typical of mast cell activation, (2) an increase of validated mast cell derived mediators, and (3) response to treatment with mast cell stabilizing or mast cell mediator-targeted therapies. Onset of mast cell activation syndrome ostensibly reflects the loss of tolerance in the mast cell compartment to nonthreatening entities and nonhazardous environmental conditions. The etiology of chronic mast cell dysregulation and associated intolerance to self-antigens or harmless entities is not well understood, but a growing number of studies point to exposure of the epithelial borders, which leads to inappropriate or excessive mast cell activation or impaired resolution of acute inflammation following neutralization of the identified pathogen. Case presentation Here we present a case of adult onset mast cell activation syndrome following scombroid poisoning. Scombroid toxicity is usually a self-limited illness, but there are individuals who have been shown to have severe symptoms or persistent illness following histamine fish poisoning. We describe a 74-year-old Caucasian woman, with a history of drug-induced urticaria, who developed a constellation of hypersensitivity illnesses consistent with the diagnosis of mast cell activation syndrome after ingestion of tainted fish. Conclusion Mast cell activation disease causes problems of increased complexity in children and adults. The increased prevalence and severity of mast cell activation disease has been attributed to dramatic changes in our lifestyles and modern living environments. These changes likely impact the integrity of the epithelial barriers, leading to loss of tolerance in the mast cell compartment. Here, we present a case of a nonatopic, 74-year-old female who developed mast cell activation disease after exposure to a potent environmental toxin. Mast cell activation disease commonly involves several organ systems, with patients often referred to a succession of different specialists. This results in delayed diagnosis and suboptimal care. Instead, early recognition of mast cell activation disease would lead to better outcomes. We review the literature, describing the diagnostic criteria for mast cell activation disorders that can improve recognition of this multiorgan system syndrome. Further research is needed into the interaction of epithelial barrier disruption and the dysregulation of the immune system.
Mast Cell Activation syndrome (MCAS) is a clinical condition, defined by the combination of 1) typical symptoms, 2) laboratory abnormalities and 3) response to treatment. Patients present with episodic symptoms of aberrant mast cell activation, such as abdominal cramping, asthma, hypotensive episodes, tachycardia, anaphylaxis, unexplained arrhythmias, and neurologic/psychiatric symptoms. Both clonal and nonclonal mast cell activation syndromes have been described, with a greater prevalence of non-clonal MCAS among the pediatric and adult population. Numerous extrinsic triggers of mast cell activation (MCA) are described, but recent reports point to nonatopic triggers, as the predominant, extrinsic stimulants of MCA in the adult population. The etiology of MCAS is unclear, though recent studies point to the disruption of the epithelium by infection, toxic exposures or physical trauma, and perturbation the tight regulation of these innate immune cells, associated to the epithelial borders. Here we describe a geriatric patient with adult onset MCAS, following a significant toxic exposure, scombroid poisoning. We also review the relevant literature regarding MCAS diagnosis and management as well as potential mechanisms for this hypersensitivity syndrome in adults.
Ehlers-Danlos syndrome first described by Tschernogobow (1896) in Moscow and Ehlers (1900) in Copenhagen is a mostly autosomal inherited genetic disease of collagen synthesis that sensitizes the ensemble of the connective tissue which becomes less resistant and less elastic. These two characteristics explain the symptomatology: fragility of the skin, of the vessels (haemorrhages) and the presence of a diffuse proprioceptive syndrome due to dysfunction of the receptors which are implanted into little or nonreactive connective tissue. Diagnosis of the hypermobile type of EDS is solely clinical as there is to date no genetic maker for the most frequent form of EDS. The rarity of the disease needs to be put into question before the crowd of patients at consultations. Our experience is based on an active database of 2212 patients which all fall under the Villefranche criteria. A great number of signs and symptoms have yet to be attributed to this syndrome. They are, combined with the unawareness of physicians about the syndrome, at the origin of therapeutic errors accompanied by the iatrogenic effects of prejudice towards these patients. This is the case of dystonia which is present in 75% of our cases. Dystonia plays an important part in the functional discomfort which is at the origin of a number of handicap situations. It seems to be related to dysautonomia common amongst the patients, proprioceptive problems and the multiple pains caused by the syndrome. Dystonia treatment with Amantadine and L-Dopa permits to obtain results which go further than the normally associated extrapyramidal treatment and opens new perspectives on the management of a syndrome that has been particularly difficult to treat. 75181, cedex 04 Paris ; E mail: pr.hamonet@wanadoo.fr was studied in parallel by the rheumatologists (Brighton and Grahame) and the geneticist (Beighton) who is working mainly on articular hypermobility with different assessment tests. There is perfect similarity between the rheumatologists' joint hypermobility syndrome and the geneticists' EDS hypermobility type. These two denominations refer in fact to the same illness. However, a great body of clinical manifestations has not yet been assigned to this syndrome. They are, in combination with the physicians' usual unawareness of this syndrome, the cause of many diagnostic wavering with their iatrogenic side-effects that harm the patients. This is the case with dystonia. Material and Methods2,212 patients were diagnosed and followed up in the EhlersDanlos consultation in Paris, between 2006 and 2015. They were all examined by the same physician with the same evaluation grid both qualitative and quantitative allowing to rate from 0 to 4 the symptoms' subjective severity and objective data from clinical examination. The population's age varies from 2years to 69 years (mean age: 32). 80% are women.
