Randomized Controlled Trial: Digital Phenotyping and Lifestyle Intervention in Patients With Myasthenia Gravis to Reduce Fatigue

Intervention / Treatment
Detailed Description
The cohort is Myasthenia Gravis (MG) patients in Sweden. The primary research question is: can digital lifestyle intervention in an online-group format improve fatigue as measured by MG-ADL in MG patients by at least 30%? Secondary research question: can lifestyle intervention improve fatigue as measured by FSS in MG by at least 30%?
The primary outcome measure is MG-ADL; the secondary outcome measures include general fatigue (fatigue severity scale and Chalder´s fatigue scale). Exploratory outcome measures include OURA-ring-based markers, including heart rate variability, temperature fluctuations, and sleep and activity parameters. These will be collected throughout the entire study period for 30 weeks.
Analysis of serum biomarkers miR-150-5p and miR-30e-5p and inflammatory proteins found upregulated in MG will be included. Clinical data at baseline: antibody status, electrophysiology, MG Composite Scale (MGC), and clinical data at follow-up visits (medications, MGC), etc., are extracted from the medical charts and the Swedish MG registry
Inclusion criteria:
- An MG diagnosis for at least six months before entry into the study.
- Both patients with ocular and generalized MG are allowed to participate.
- For practical reasons, participants need to understand Swedish.
Exclusion criteria:
- Participation in another clinical trial in the past 6 months.
- Disease duration less than 6 months.
- Contraindications to physical activity: unstable coronary syndrome or myocardial infarction within the preceding three months, respiratory failure (vital capacity < 70% predicted value) or cardiac failure (ejection fraction < 50% predicted value), concomitant neuromuscular diseases, disabling rheumatological disease (> 80% disability on the Barthel scale), chronic pain or disabling orthopedic conditions, hospitalization in the last three months for a serious medical or surgical condition, anemia (hematocrit < 30%), stroke within the previous year.
- MG patients already performing a moderate-intensity physical activity of 150min or more per week, i.e., one of the target interventions.
- Pregnancy.
Each participant is enrolled in the study for 7 months, and 26 persons are randomized to one of the following 3 groups:
- Group 1; no intervention, observation with the OURA ring.
- Group 2: 12 weeks of physical activity guidance with short discussions via digital meetings regularly. They will conduct at least 150 minutes per week of moderate-intensity exercises. Brisk walks are the primary choice of activity; alternatively, swimming, cycling, or dancing to the physical exertion according to the Borg scale can be performed.
- Group 3: 12 weeks of sleep exercises. The lifestyle intervention of sleep will be delivered via an online group, with recommended home practices between sessions. Topics covered will include sleep education, sleep hygiene, and practices to improve sleep quality.
The study is digital and will use the platform "minforskning.se", which is validated according to GCP-GAMP5 and has the potential to collect digital consent forms.

Description
Inclusion Criteria:
- The MG disease status must be stable for at least six months before entry into the study; thus, the duration of the disease must be at least six months.
- Both patients with ocular and generalized MG are allowed to participate.
- For practical reasons, participants need to be able to understand fully and communicate in Swedish.
Exclusion Criteria:
- Participation in another clinical trial in the past 6 months.
- Disease duration less than 6 months.
- Contraindications to physical activity: unstable coronary syndrome or myocardial infarction within the preceding three months, respiratory failure (vital capacity < 70% predicted value) or cardiac failure (ejection fraction < 50% predicted value), concomitant neuromuscular diseases, disabling rheumatological disease (> 80% disability on the Barthel scale), chronic pain or disabling orthopedic conditions, hospitalization in the last three months for a serious medical or surgical condition, anemia (hematocrit < 30%), stroke within the previous year.
- MG patients already performing moderate-intensity physical activity of 150min or more per week, i.e., one of the target interventions.
- Pregnancy.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Observation
Observation with the OURA ring and no digital meetings.
The participants are offered delayed randomization after the study period.
This group's outcome from the delayed randomization will be for the exploratory analysis, i.e., not in the primary analysis.
|
|
Experimental: Physical activity
12 weeks of physical activity guidance with short discussions via online group meetings according to a schedule.
The participants in this arm will conduct moderate-intensity exercises for at least 150 minutes per week.
Brisk walks are the primary choice of activity; alternatively, swimming, cycling, or dancing to the physical exertion according to the Borg scale can be performed.
|
Intervention with physical activity more than 150 minutes of medium to high intensity per week.
|
Active Comparator: Sleep hygiene intervention
12 weeks of sleep exercises.
The lifestyle intervention of sleep will be delivered via an online group, with recommended home practices between sessions.
Topics covered will include sleep education, sleep hygiene, and practices to improve sleep quality.
|
Intervention with sleep hygiene to optimize sleep duration and quality.
