Estimation of Non-Reimbursable Costs for Patients With Duchenne Muscular Dystrophy in France

Duchenne muscular dystrophy (DMD) is a chronic neuromuscular disorder affecting approximately 150 to 200 newborns annually, predominantly males, and is characterized by progressive muscle atrophy and weakness due to a complete absence of dystrophin. DMD presents a severe phenotype, with life expectancy typically extending into the third decade. Data on healthcare utilization and associated costs for DMD patients, particularly within the French healthcare context, remain limited. The EPARDYS study aims to examine the care pathways of these patients using data from the Banque Nationale des Données Maladies Rares (BNDMR) and the Système National des Données de Santé (SNDS), enabling a detailed characterization of patient demographics, healthcare utilization patterns, and associated costs. However, only direct costs eligible for reimbursement under the Affection Longue Durée (ALD 100%) scheme can be evaluated. Additional resources are consumed by DMD patients, particularly for medical care that falls outside the scope of reimbursement. Furthermore, the high level of dependency in these patients may lead to the need for home adaptations or other expenditures outside the healthcare domain but linked to the disease. Informal caregiving also plays a significant role. These additional family-incurred costs must be considered. The CouDuMyo study will aim to estimate all relevant cost components from a societal perspective, considering both minors and adults, whether they attend school or work. The medico-social aspect of care, along with the collection of data on aids and benefits received, will offer insights into the nature of the support available to families in France. The knowledge gained regarding non-reimbursable, disease-related costs according to patient characteristics will provide a comprehensive view of the financial burden borne by patients and their caregivers. This assessment is particularly relevant in the context of emerging therapies, which may reduce these associated costs. The main objective will be to describe the resource utilization associated with DMD care that is not eligible for reimbursement, including direct medical costs not covered, medico-social expenses, direct non-medical costs, and indirect costs.

Wearable Technology to Evaluate Hyperglycemia and HRV in DMD

Duchenne muscular dystrophy (DMD) is an X-linked disorder that causes muscle wasting, cardiopulmonary failure, and premature death. Heart failure is a leading cause of death in DMD, but substantial knowledge gaps exist regarding predisposing risk factors. In the general population, hyperglycemia, insulin resistance, and decreased heart rate variability (HRV; reflecting autonomic dysfunction) are associated with cardiomyopathy (CM). It is unclear whether these factors are associated with DMD-CM. Closing this knowledge gap may lead to novel screening and therapeutic strategies to delay progression of DMD-CM, now the leading cause of death in patients with DMD. Despite risk factors for hyperglycemia, including the use of glucocorticoids (GCs), sarcopenia, obesity, and reduced ambulation, little is known regarding glucose abnormalities in DMD. Some of these same risk factors, along with the distance needed to travel for specialty care, present significant barriers to research participation and clinical care for individuals with DMD. Remote wearable technology may improve research participation in this vulnerable population. Therefore, this study will leverage remote wearable technologies to overcome these barriers and define the relationship between dysglycemia and DMD-CM. The goal of this remote study is to evaluate rates of hyperglycemia in individuals with DMD compared to control participants using continuous glucose monitors, and to determine the relationship between hyperglycemia and heart rate variability. Participants will utilize continuous glucose monitors, cardiac monitors, and activity monitors to evaluate glucose levels, heart rate, activity, and sleep.

Target: improved muscle function, vascular health, and DMD treatment.

Tele-assessment of Functional Performance and Quality of Life in Patients With Duchenne Muscular Dystrophy: Validity and Reliability Study

Thanks to tele-assessment methods, it may be possible to evaluate DMD patients without traveling to clinical centers. In recent years, the applicability of remote assessment methods in DMD patients, as in many populations, is being investigated. However, studies have generally focused on a single evaluation parameter such as physical function, a special evaluation method or a special evaluation tool. The aim of this study is to investigate whether remote assessment of functional performance and quality of life in DMD patients is valid and reliable. If a valid and reliable tele-evaluation method that includes functional performance and quality of life parameters is found to be valid and reliable, the travel burden on patients and caregivers can be eased, patients\&#39; stress and anxiety related to travel can be reduced, caregivers can save time and energy and provide patients with the best possible treatment.
