Mechanobiology in the Comorbidities of Ehlers Danlos Syndrome

Pediatric Outcomes After Robotic Median Arcuate Ligament Release, Celiac Ganglionectomy, and Lymphadenectomy

BACKGROUND

Median arcuate ligament syndrome (MALS) is a neurovascular disorder characterized by gastrointestinal symptoms due to celiac artery and ganglion compression. Limited literature primarily focuses on adults. This study aims to characterize clinical and histopathologic findings in pediatric MALS.

METHODS

Patients <18 years undergoing robotic MAL release, celiac ganglionectomy, and lymphadenectomy from 2020 to 2024 were evaluated. Clinical and histopathologic outcomes were analyzed.

RESULTS

Twelve patients met inclusion criteria and were reviewed (15.7 ± 1.2 years, 75% female, BMI 20.9 [18.6-24.0] kg/m2). Comorbidities included depression/anxiety (83%), postural orthostatic tachycardia syndrome (POTS) (50%), gastroesophageal reflux disease (GERD) (50%), nutrition support (50%), mast cell activation syndrome (MCAS) (42%), hypermobile Ehlers-Danlos syndrome (hEDS) (42%), other vascular compression syndromes (33%). All patients who received preoperative celiac plexus block had temporary symptom relief (10/10). Mean operative time was 119.7 ± 22.4 min. No intraoperative complications, 30-day readmissions, reoperations, or complications occurred. Histopathologically, 92% had fibroadipose tissue, 100% had reactive lymph nodes, none had intraparenchymal nerves, and one had lipogranulomas. Median fibrosis scores were 1 [0.5-2] on H&E and 2 [1-2] on trichrome. Fibrosis score severity was not significantly associated with symptom improvement (χ2 = 3.67, p = 0.16). Median postoperative celiac artery velocity was 258.5 [192.5-350.5] cm/s with a median change of -80.5 [-106.1-+82.8] cm/s from preoperative 308.0 [229.3-344.0] cm/s (S = -5.0, p = 0.55). Those with lower preoperative velocities were more likely to have symptom improvement postoperatively (S = 19, p = 0.04). MALS symptoms improved in 83%; however, despite reporting "MALS pain" was improved, 64% (all female) had other comorbidities such as POTS, MCAS, hEDS, and colonic dysmotility contributing to other ongoing symptoms.

CONCLUSION

Robotic MALS surgery is safe and effective in pediatrics. Clinical improvement rates and fibrosis scoring are comparable to adults; however, findings reveal challenges with multiple comorbidities contributing to separate symptoms that may continue postoperatively, particularly in females. We recommend a multidisciplinary team approach in addressing comorbidities and optimizing medical and surgical care.

Integrative medicine for hypermobility spectrum disorders (HSD) and Ehlers-Danlos syndromes (EDS): a feasibility study

PURPOSE

Hypermobility spectrum disorders (HSD) and Ehlers-Danlos syndromes (EDS) are multisystem conditions marked by dysfunctional connective tissue. This feasibility study evaluated a 9-week integrative medicine program in this population.

METHODS

Using a single-arm study design, adults with HSD or EDS were given recommendations for an anti-inflammatory Mediterranean diet and self-management with additional behavioral and psychosocial support. Preliminary data on feasibility based on recruitment and retention, adherence to the diet, mobile app tracking, changes to perceived well-being via health outcomes, and satisfaction with care were obtained.

RESULTS

Thirteen participants were enrolled within a 4-month timeframe. Eight participants completed the study. Three participants met dietary tracking requirement in at least 4 of 8 intervention weeks and met the macronutrient requirements in at least half of the weeks tracked. No decreases in VAS pain scores after 5 and 9 weeks were noted; however, 62.5% (n = 5) of participants had decreased pain at 9 weeks, compared to baseline. There were significant improvements (p<.05) in six of twelve measurements of satisfaction with care at the end of the intervention.

CONCLUSION

This study provides a foundation for future research on patient experience and introduces a novel treatment paradigm focused on nutrition and self-management.

Trial Registration: National Institutes of Health clinicaltrials.gov; identifier: NCT04734041.

IMPLICATIONS FOR REHABILITATION

Lifestyle and dietary interventions are relatively safe and well tolerated in the hypermobility spectrum disorder (HSD) and Ehlers-Danlos disorder (EDS) population.Participants in our 9-week integrative medicine program actively engaged in self-management of their condition and showed promising adherence to dietary and tracking requirements.Effective treatment of the intricacies and dynamics of these highly variable and clinically heterogeneous disorders may require a network of healthcare providers, integrative healthcare, as well as behavioral and psychosocial support.Dietary tracking through mobile apps might help promote self-efficacy and adherence to dietary changes.Symptom tracking might be an effective way for patients to track changes to their health and could provide valuable information for health professionals engaged in managing the disorders.

Mast Cell Involvement in the Pathogenesis of Selected Musculoskeletal Diseases

In recent years, there has been a noteworthy revival of interest in the function of mast cells (MCs) in the human body. It is now acknowledged that MCs impact a wide array of processes beyond just allergies, leading to a shift in research direction. Unfortunately, some earlier conclusions were drawn from animal models with flawed designs, particularly centered around the receptor tyrosine kinase (Kit) pathway. Consequently, several subsequent findings may have been unreliable. Thus, what is now required is a re-examination of these earlier findings. Nevertheless, the remaining data are fascinating and hold promise for a better comprehension of numerous diseases and the development of more effective therapies. As the field continues to progress, many intriguing issues warrant further investigation and analysis. For instance, exploring the bidirectional action of MCs in rheumatoid arthritis, understanding the extent of MCs' impact on symptoms associated with Ehlers-Danlos syndrome, and unraveling the exact role of the myofibroblast-mast cell-neuropeptides axis in the joint capsule during post-traumatic contractures are all captivating areas for exploration. Hence, in this review, we summarize current knowledge regarding the influence of MCs on the pathogenesis of selected musculoskeletal diseases, including rheumatoid arthritis, spondyloarthritis, psoriatic arthritis, gout, muscle and joint injuries, tendinopathy, heterotopic ossification, and Ehlers-Danlos syndrome. We believe that this review will provide in-depth information that can guide and inspire further research in this area.

The value of dynamic elastomeric fabric orthoses in the management of a complex hypermobile Ehlers-Danlos syndrome patient: A case report

The use of dynamic elastomeric fabric orthoses is examined in a young woman with hypermobile Ehlers-Danlos syndrome (hEDS) referred for physiotherapy with hip dysplasia, prior to a right periacetabular osteotomy. Dynamic elastomeric fabric orthoses plus rigorous subjective examination, therapists' listening skills, and patient-centered goals were useful for this hEDS patient.
