Обзор

CONTEXTE. Myasthenia gravis is a rare neuromuscular junction disorder affecting one in five thousand people (ORPHA 589). It is a chronic condition that progresses in episodes. Its severity varies, ranging from the invisible disability of fatigue to respiratory distress requiring intensive care. Currently, 270 patients with myasthenia gravis are being treated at Grenoble University Hospital in the Reference Centre for Rare Neuromuscular Diseases. The impact of this disease on quality of life is significant, and medication alone is not sufficient. However, to date, there are virtually no psychosocial interventions for patients with myasthenia gravis and no studies evaluating their effectiveness. In this context, the Cognitive Behavioural Stress Management (CBSM) programme is one of the stress management programmes applied to chronic health conditions whose effectiveness has already been demonstrated, particularly in terms of treatment adherence, quality of life, patients' coping strategies in the face of a chronic illness, and the outcomes of medical treatments (Antoni, 2003; Antoni et al., 2002, 2006). PRIMARY OBJECTIVE. Evaluation of the adaptation of an existing patient education programme, 'Living Better with Myasthenia', following the inclusion of an eight-session CBSM-based stress management module for adult patients living with myasthenia. METHODOLOGY (brief). Adaptation of the CBSM programme to the specific characteristics of myasthenia gravis: 1. Focus groups: exploration of beliefs associated with stress in myasthenia gravis. 2. DELPHI group: validation of the adaptation of the ETP programme 'Living better with myasthenia gravis' implemented at CHUGA following the inclusion of a stress management module (CBSM). Assessment of the feasibility of the MY-EDUC programme among groups of patients with myasthenia gravis. PRIMARY OUTCOME MEASURE. Comparison of levels of anxiety, depression (HADS), perceived stress (PSS) and quality of life (SF-36) as self-reported by patients enrolled in the programme before and after the MY-EDUC intervention. RESEARCH PROCEDURE. 1.1. FOCUS GROUPS. Expert patients and partner patients. They will be contacted via the list maintained by the rare disease healthcare network. 'General public' patients. A call for participants will be displayed in the CHUGA waiting room and circulated by partner organisations to their members. The study will be presented to expert and partner patients, as well as to "walk-in" patients in the focus groups, using the contact details on the "rare disease healthcare network" lists and via posters. An information leaflet outlining the study and its objectives will be provided to them. 1.2. FEASIBILITY AND ACCEPTABILITY STUDY OF THE MY-EDUC PROGRAMME. 1.2.1. Participant inclusion. Patient eligibility. The assessment of patient eligibility will be carried out by a specialist doctor from the CHUGA Rare Disease Centre of Excellence during a routine consultation with the patient (routine care). Participant inclusion. Once patient eligibility has been verified, the investigator from the CHUGA Rare Disease Centre, or a person to whom they have delegated this task, will contact the patient to invite them to participate in the MY-EDUC study. They will provide a verbal explanation of the study and hand over an information sheet during a follow-up consultation with the patient as part of routine care. If the patient volunteers to participate, they will give their consent to participate. The patient's consent will be recorded in the medical record. 1.2.2. Baseline assessment (T0). In the week leading up to the first session of the MY-EDUC programme, participants will complete the baseline assessment online (using the LimeSurvey platform - secure servers at the University of Grenoble Alpes) with questionnaires presented in a randomised order. 1.2.3. Assessment during the intervention (T1). Based on repeated ecological measurements (Shiffman et al., 2008) via the study participants' mobile phones (two measurement points, before and after each session, randomly scheduled at least 36 hours apart, i.e. 16 measurements) using the free PielsSurvey software. 1.2.4. Final assessments (T2 and T3). Within one week of the final session of the MY-EDUC programme (T2: week 10 after T0), participants will complete a set of questionnaires electronically (using the LimeSurvey platform - secure servers at the University of Grenoble Alpes), with the validated questionnaires presented in a randomised order.

Подробное описание

1. Background and Rationale Myasthenia Gravis (MG) is a rare autoimmune disorder of the neuromuscular junction (ORPHA 589), characterised by its chronic nature and the occurrence of fluctuating symptoms or flare-ups. Beyond the physical manifestations, the condition has a major impact on patients' quality of life. Recent data suggest that approximately 46.3% of patients suffer from anxiety disorders. While a Therapeutic Patient Education (TPE) programme entitled "Living better with myasthenia" is already established at Grenoble University Hospital, patients have expressed a clear requirement for specific modules addressing stress and anxiety management.

The MY-EDUC programme aims to adapt the current TPE framework by integrating a stress management module based on Cognitive Behavioural Stress Management (CBSM). CBSM has proven effectiveness in various chronic pathologies for improving treatment adherence, quality of life, and coping strategies. 2. Objectives Primary Objective: To evaluate the adaptation of the existing TPE programme after incorporating a CBSM-based stress management module (8 sessions) for adult patients with myasthenia gravis.

Secondary Objectives: To assess the feasibility and acceptability of the MY-EDUC programme. 3. Study Design and Methodology

This is an observational, prospective, descriptive, and monocentric study (classified as RIPH3 under French regulations). The research is conducted in three phases:

Phase 1 (Focus Groups): Exploration of stress-related beliefs with both expert patients and regular patients to adapt the session content.

Phase 2 (Feasibility Study): Implementation of the programme with 40 patients (organised into 5 groups of 8 participants maximum). 4. Description of the Intervention (MY-EDUC) The programme consists of 8 weekly sessions. It combines transversal stress management modules with modules specifically tailored to myasthenia. The approach is modular and transdiagnostic, designed to facilitate future national rollout within the FILNEMUS network. 5. Outcome Measures and Assessments Assessments are performed electronically (via LimeSurvey) at several intervals: T0 (baseline), T1 (during the intervention via repeated ecological momentary assessments on smartphones), T2 (post-intervention), and T3 (1-month follow-up).

Psychological Measures: Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS), and Brief COPE.

Quality of Life: 36-Item Short Form Survey (SF-36).

Ecological Assessments: Evaluation of stress and anxiety levels before and after each session (16 measurement points via PielsSurvey). 6. Statistical Analysis Plan

Data analysis will include:

Descriptive statistics of the population's demographic and medical characteristics.

Analysis of Covariance (ANCOVA) to compare means between groups at different time points.

Repeated measures Analysis of Variance (ANOVA) to evaluate the sustainability of the effects.

Multivariate linear regressions and network analyses to explore interactions between variables and identify subgroups of responders to the intervention. 7. Expected Results The study intends to demonstrate that a TPE programme enhanced by a cognitive-behavioural approach reduces anxiety and depression while improving pain management and overall quality of life. Ultimately, this modular model could be transposed to other rare diseases, such as Amyotrophic Lateral Sclerosis (ALS).

Вмешательства

• Поведенческое CBSM
  Cognitive Behavioural Stress Management (CBSM) is a structured, multimodal psychological intervention based on the transactional model of stress. It addresses the distress arising from the perceived imbalance between disease-related threats and available coping resources. CBSM aims to disrupt the cycle of physical symptoms and psychological strain. The intervention integrates several core evidence-based techniques: Cognitive Restructuring: Identifying and challenging dysfunctional thoughts rel
