Management of childbearing with hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders: A scoping review and expert co-creation of evidence-based clinical guidelines. PLoS One 2024; 19:e0302401. [PMID: 38748660 PMCID: PMC11095771 DOI: 10.1371/journal.pone.0302401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 04/02/2024] [Indexed: 05/19/2024] Open
Abstract
OBJECTIVE To co-create expert guidelines for the management of pregnancy, birth, and postpartum recovery in the context of hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD). DESIGN Scoping Review and Expert Co-creation. SETTING United Kingdom, United States of America, Canada, France, Sweden, Luxembourg, Germany, Italy, and the Netherlands. SAMPLE Co-creators (n = 15) included expertise from patients and clinicians from the International Consortium on the Ehlers-Danlos syndromes and Hypermobility Spectrum Disorders, facilitated by the Ehlers-Danlos Society. METHODS A scoping review using Embase, Medline, the Cochrane Central Register of Controlled Trials and CINHAL was conducted from May 2022 to September 2023. Articles were included if they reported primary research findings in relation to childbearing with hEDS/HSD, including case reports. No language limitations were placed on our search, and our team had the ability to translate and screen articles retrieved in English, French, Spanish, Italian, Russian, Swedish, Norwegian, Dutch, Danish, German, and Portuguese. The Mixed Methods Appraisal Tool was used to assess bias and quality appraise articles selected. The co-creation of guidelines was based on descriptive evidence synthesis along with practical and clinical experience supported by patient and public involvement activities. RESULTS Primary research studies (n = 14) and case studies (n = 21) including a total of 1,260,317 participants informed the co-creation of guidelines in four overarching categories: 1) Preconceptual: conception and screening, 2) Antenatal: risk assessment, management of miscarriage and termination of pregnancy, gastrointestinal issues and mobility, 3) Intrapartum: risk assessment, birth choices (mode of birth and intended place of birth), mobility in labor and anesthesia, and 4) Postpartum: wound healing, pelvic health, care of the newborn and infant feeding. Guidelines were also included in relation to pain management, mental health, nutrition and the common co-morbidities of postural orthostatic tachycardia syndrome, other forms of dysautonomia, and mast cell diseases. CONCLUSIONS There is limited high quality evidence available. Individualized strategies are proposed for the management of childbearing people with hEDS/HSD throughout pregnancy, birth, and the postpartum period. A multidisciplinary approach is advised to address frequently seen issues in this population such as tissue fragility, joint hypermobility, and pain, as well as common comorbidities, including dysautonomia and mast cell diseases.

[PMID: 38392604 PMCID: PMC10890060 DOI: 10.3390/jpm14020170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/16/2024] [Accepted: 01/27/2024] [Indexed: 02/24/2024] Open
Abstract
Postural orthostatic tachycardia syndrome (POTS) is a common accompaniment of a variety of chronic, inflammatory diseases, including long COVID, as are small, insoluble, 'fibrinaloid' microclots. We here develop the argument, with accompanying evidence, that fibrinaloid microclots, through their ability to block the flow of blood through microcapillaries and thus cause tissue hypoxia, are not simply correlated with but in fact, by preceding it, may be a chief intermediary cause of POTS, in which tachycardia is simply the body's exaggerated 'physiological' response to hypoxia. Similar reasoning accounts for the symptoms bundled under the term 'fatigue'. Amyloids are known to be membrane disruptors, and when their targets are nerve membranes, this can explain neurotoxicity and hence the autonomic nervous system dysfunction that contributes to POTS. Taken together as a system view, we indicate that fibrinaloid microclots can serve to link POTS and fatigue in long COVID in a manner that is at once both mechanistic and explanatory. This has clear implications for the treatment of such diseases.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6955. [PMID: 37887694 PMCID: PMC10606217 DOI: 10.3390/ijerph20206955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 08/08/2023] [Accepted: 10/18/2023] [Indexed: 10/28/2023]
Abstract
Individuals living with hypermobile Ehlers-Danlos syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) have reported feeling discredited and unsupported by healthcare professionals. However, the level of knowledge about hEDS/HSD among maternity staff remains unknown. Informed by patient and public involvement, this research aimed to investigate maternity staff's knowledge and confidence in supporting people with hEDS/HSD, examine people with hEDS/HSD's experiences of perinatal care, and co-create tools to help maternity staff support people childbearing with hEDS/HSD. Two online mixed-methods international surveys were completed by childbearing people with hEDS/HSD (N = 955) and maternity staff (N = 307). This was followed by the co-creation of three tools with 17 co-creators and a design team. Two main qualitative themes were identified through thematic analysis: (1) a need for recognition of hEDS/HSD in perinatal care and (2) the delivery of appropriate individualised perinatal care. Quantitatively, people with hEDS/HSD perceived maternity professionals to have a low level of knowledge about the conditions. Respectively, maternity staff reported low levels of confidence in supporting people with hEDS/HSD. The co-created tools provide applicable outputs for both education and practice and include an i-learn module hosted by the Royal College of Midwives, a tool for perinatal records, and infomercials.

Abstract
OBJECTIVE To evaluate the relationship between postural orthostatic tachycardia syndrome (POTS) and pregnancy. DESIGN Cross-sectional survey. SETTING International. SAMPLE A total of 8941 female patients with a diagnosis of POTS. METHODS Data from the survey were analysed using descriptive measures and stratified for comparisons. MAIN OUTCOME MEASURES Symptom course of POTS during pregnancy. Secondary outcomes included pregnancy loss, POTS onset during pregnancy and the impacts of a comorbid diagnosis of Ehlers-Danlos syndrome or an autoimmune disorder on symptoms during pregnancy. RESULTS Overall, 40.8% (n = 3652) of participants reported one or more pregnancies. Most participants experienced worsening of symptoms in the first (62.6%) and third (58.9%) trimesters and 3 months after pregnancy (58.7%), and 81.1% experienced worsening symptoms at any point in their pregnancy. Most participants with worsening symptoms in the first trimester also experienced worsening symptoms in the second (61.6%) and third (68.1%) trimesters, but if they improved in the first trimester then this improvement persisted in the second and third trimesters. Of participants who reported that POTS was triggered by a specific event (41.3%), 8.1% reported pregnancy as the trigger for the onset. CONCLUSIONS Postural orthostatic tachycardia syndrome symptoms in the first trimester of pregnancy may help predict symptom course throughout the duration of pregnancy. Some individuals may experience an initial onset of POTS during pregnancy. This novel information may guide clinicians in counselling patients with POTS who are planning pregnancy.

Abstract
Postural Orthostatic Tachycardia Syndrome (POTS) is a disorder of the autonomic nervous system most commonly affecting women of reproductive age. Studies on POTS and pregnancy are limited, and there is a lack of clinical guidelines regarding assessment and management of pregnant women with POTS. The purpose of this review is to summarize data from the available studies on the topic of pregnancy in POTS and common comorbid conditions and to provide the clinical recommendations regarding evaluation and treatment of POTS in pregnant women, based on the available studies and clinical experience. We conclude that pregnancy appears to be safe for women with POTS and is best managed by a multi-disciplinary team with knowledge of POTS and its various comorbidities. Importantly, large, prospective studies are needed to better delineate the course and outcomes of pregnancy, as well as possible pregnancy-related complications in women with POTS. Clinicians should be aware of the clinical presentation, diagnostic criteria, and treatment options in pregnant women with POTS to optimize outcomes and improve medical care during pregnancy and post-partum period.

Abstract
Objective. To review the scientific publications reporting vagal nerve somatosensory-evoked potential (VSEP) findings from individuals with brain disorders, and present novel physiological explanations on the VSEP origin. Methods. We did a systematic review on the papers reporting VSEP findings from individuals with brain disorders and their controls. We evaluated papers published from 2003 to date indexed in PubMed, Web of Science, and Scielo databases. We extracted the following information: number of patients and controls, type of neural disorder, age, gender, stimulating/recording and grounding electrodes as well as stimulus side, intensity, duration, frequency, and polarity. Information about physiological parameters, neurobiological variables, and correlation studies was also reviewed. Representative vignettes were included to add support to our conclusions. Results. The VSEP was studied in 297 patients with neural disorders such as Parkinson's disease (PD), Alzheimer's disease, vascular dementia, mild cognitive impairment, subjective memory impairment, major depression, and multiple sclerosis. Scalp responses marked as the VSEP showed high variability, low validity, and poor reproducibility. VSEP latencies and amplitudes did not correlate with disease duration, unified PD rating scale score, or heart function in PD patients nor with cerebrospinal fluid β amyloid, phosphor-τ, and cognitive tests from patients with mental disorders. Vignettes demonstrated that the VSEP was volume conduction propagating from muscles surrounding the scalp recording electrodes. Conclusion. The VSEP is not a brain-evoked potential of neural origin but muscle activity induced by electrical stimulation of the tragus region of the ear. This review and illustrative vignettes argue against assessing the parasympathetic system using the so-called VSEP.

Abstract
Many neuromuscular disorders preexist or occur during pregnancy. In some cases, pregnancy unmasks a latent hereditary disorder. Most available information is based on case reports or series or retrospective clinical experience or patient surveys. Of special interest are pregnancy-induced changes in disease course or severity and likelihood for baseline recovery of function postpartum. Labor and delivery present special challenges in many conditions that affect skeletal but not smooth (uterine) muscle; so labor complications must be anticipated. Anesthesia for cesarean section surgery requires special precautions in many disorders. The types of conditions reviewed are broad and include examples of autoimmune, hereditary, and compressive/mechanical processes. Disorders include carpal tunnel syndrome and other focal neuropathies, Bell palsy, myasthenia gravis, and other neuromuscular junction disorders, acute and chronic inflammatory neuropathy, hereditary and acquired muscle diseases, spinal muscular atrophy, amyotrophic lateral sclerosis, channelopathies, autonomic neuropathy, and dysautonomia. Many commonly used therapies have fetal animal but no proven human toxicity concerns, complicating treatment and risk decisions. Weaning off effective therapeutic agents or preemptive aggressive treatment or surgery prior to planned pregnancy is an option in some conditions.
