Home-Based High-Intensity Interval Training in Systemic Lupus Erythematosus (MIGHT-SLE)
Exercise and Muscle Biology in Systemic Lupus Erythematosus
Systemic lupus erythematosus, or SLE, is a chronic autoimmune disease that can cause persistent fatigue, muscle pain, reduced physical function, and impaired quality of life, even when the disease is otherwise clinically stable. The biological mechanisms contributing to these symptoms are not fully understood. Abnormal energy production within skeletal muscle and increased fat accumulation within the muscle may contribute to fatigue and reduced physical performance in people with SLE.
This pilot study will evaluate the effects of a 16-week personalized, home-based exercise program in 20 adults with stable SLE and clinically significant fatigue. The program will include three exercise sessions per week: bodyweight high-intensity interval training, strength training, and walking-based interval training. Sessions will be adapted to each participant's fitness, mobility, symptoms, and exercise tolerance. Some sessions will be supervised remotely by video, while others will be completed independently using personalized recorded instructions.
Participants will undergo assessments before and after the 16-week program. These assessments will examine skeletal muscle mitochondrial function, fat accumulation within the thigh muscles, physical performance, fatigue, quality of life, and blood-based markers of mitochondrial function and inflammation.
The study will help determine whether a personalized home-based exercise program can improve muscle health and physical function in people with SLE and will provide information needed to design larger future studies.

Descrição detalhada
This is a single-arm, pilot, proof-of-concept study evaluating the clinical and biological effects of a 16-week personalized, home-based high-intensity interval training program in 20 adults with stable systemic lupus erythematosus and persistent fatigue and/or muscle pain.
SLE-related fatigue is common and may persist despite adequate control of inflammatory disease activity. Skeletal muscle mitochondrial dysfunction may impair cellular energy production and contribute to fatigability and exercise intolerance. In addition, intermuscular adipose tissue, defined as fat located within the muscle compartment, is increased in some people with SLE and may be associated with systemic inflammation, fatigue, and reduced physical function.
The exercise intervention will include three sessions per week:
One bodyweight high-intensity interval training session One strength-training session One walking-based high-intensity interval training session
Exercise duration and intensity will increase gradually during the 16-week intervention. The program will be personalized according to each participant's baseline fitness, mobility, exercise preferences, SLE manifestations, pain, and exercise tolerance. Exercise sessions will alternate between remotely supervised video sessions and self-directed sessions using individualized prerecorded videos. Participants will use a heart-rate monitor during exercise, and the study team will conduct regular check-ins to support adherence and safety. Exercise intensity may be reduced or modified if a participant develops increased pain, joint symptoms, or an SLE flare.
Participants will complete study assessments at baseline and after the 16-week intervention. Skeletal muscle mitochondrial function will be assessed noninvasively using phosphorus-31 magnetic resonance spectroscopy. The primary measure of mitochondrial function will be phosphocreatine recovery following a brief standardized muscle exercise.
Magnetic resonance imaging of the thigh will be used to quantify intermuscular adipose tissue and muscle composition. Additional imaging may assess abdominal and liver fat.
Physical performance will be evaluated using the six-minute walk test and the 30-second sit-to-stand test. Participants will also complete questionnaires assessing fatigue, fatigability, mobility, overall health, cognitive function, and SLE-related quality of life.
Blood and other biological samples will be collected before and after the intervention. Laboratory analyses will evaluate circulating markers of mitochondrial function, inflammation, and inflammasome activation. Exploratory analyses may include gene expression, proteomic, genetic, urine, and microbiome studies for participants who provide the required consent.
The study will compare each participant's measurements before and after the exercise intervention. The primary outcomes will evaluate changes in skeletal muscle mitochondrial function and intermuscular adipose tissue. Secondary and exploratory analyses will evaluate changes in physical performance, fatigue, quality of life, inflammatory markers, and other biological measures.
Because this is a small, uncontrolled pilot study, it is intended to identify preliminary signals of biological and clinical benefit rather than establish definitive efficacy. Results will inform the feasibility, outcome selection, and sample-size planning of future controlled trials of personalized exercise interventions in SLE.

Participants will complete a 16-week personalized, home-based, moderate- to high-intensity exercise program. The program includes three sessions per week: bodyweight high-intensity interval training, strength training using bodyweight, light weights, or resistance bands, and walking-based high-intensity interval training. Exercise intensity and duration will progress gradually and will be individualized according to baseline fitness, mobility, disease manifestations, pain, and exercise tolerance. Video-supervised sessions with an exercise trainer will alternate with self-directed sessions using personalized prerecorded videos. Participants will use a heart-rate monitor during exercise and will record perceived exertion. The study team will monitor adherence and safety and will conduct regular telephone or text check-ins. Exercise intensity and activities may be modified during increased joint symptoms or an SLE flare.

Change From Baseline in Phosphocreatine Recovery Half-Time at Week 16
Prazo: Baseline and Week 16
|
Skeletal muscle mitochondrial oxidative capacity will be assessed using phosphorus-31 magnetic resonance spectroscopy (31P-MRS) of the thigh.
Following a standardized knee-extension exercise, the phosphocreatine recovery half-time will be calculated in seconds.
The recovery half-time is the time required to restore one-half of the phosphocreatine depleted during exercise.
A shorter recovery half-time indicates faster recovery and greater skeletal muscle mitochondrial oxidative capacity.

Change From Baseline in Thigh Intermuscular Adipose Tissue at Week 16
Prazo: Baseline and Week 16
|
Intermuscular adipose tissue will be quantified from magnetic resonance imaging of the thigh.
Intermuscular adipose tissue will be expressed as the percentage of adipose tissue located within the muscle compartment relative to the total muscle compartment.
A lower percentage indicates less intermuscular adipose tissue accumulation.
