- Registration Number
- NCT06166199
- Lead Sponsor
- Karolinska Institutet
- Brief Summary
The aim of this study is to evaluate the safety and effects of high-intensity interval training (HIIT) combined with resistance training in patients with systemic lupus erythematosus
- Detailed Description
The overall aim of this randomized controlled study, is to evaluate the safety and effects of HIIT combined with resistance exercises on aerobic capacity, muscle function, patient reported outcomes, disease activity and immune function in patients with SLE with low to moderate disease activity and no to little organ damage. The aim is also to explore and describe patient's experiences of the training.
The research questions are:
1. What are the differences between the HIIT combined with resistance exercises and a control group, after 3 months of supervised training and after further 3 months of self training with video-call/telephone support until 6 months follow up, regarding aerobic capacity, muscle function, physician and patient reported disease activity, fatigue, depressive symptoms, and quality of life?
2. What are the differences between the HIIT combined with resistance exercises and a control group, after 3 months of supervised training and after further 3 months of self training with video-call/telephone support until 6 months follow up, regarding inflammatory markers such as interleukin 6 and 10 and interferon molecules? Both acute exercise test (maximal ergometercycle test) effects as well as the long term effects of training will be evaluated.
3. How do individuals with SLE experience HIIT combined with resistance exercises ? What are the perceived barriers and facilitators for performing and maintaining such training?

Group Intervention Description High-intensity interval training (HIIT) combined with resistance training HIIT combined with resistance training Patients with SLE will undergo supervised HIIT on an ergometercycle 4 x 4 minutes interval (85-90% of maximal heart rate in 4 minutes and lower intensity for another 4 minutes etc). The HIIT is combined with resistance exercises for upper and lower extremity. In total the supervised training takes around 50 minutes per occasion and will be performed 2 times/week, for 3 months. In addition, the patients will exercise, according to the program, by themselves once a week. Between months 3 and 6 the patients exercise by themselves, 3 times/week, with video-call/telephone support from a physiotherapist once a week.
- Primary Outcome Measures
Name Time Method Aerobic capacity Baseline, months 3 and 6 Aerobic capacity is measured as maximal oxygen uptake when performing a maximal symptom-limited, ergometercycle exercise test
Physical capacity Baseline, months 3 and 6 Physical capacity are measured when performing a symptom-limited, ergometercycle exercise test
- Secondary Outcome Measures
Name Time Method Muscle function upper extremity Baseline, months 3 and 6 How many shoulder flexions (0-90 degrees), in a given pace, with a 3 kg (men) or 2 kg (women) dumbbell in the hand is possible to do
Health status Baseline, months 3 and 6 The patient-reported questionnaire EuroQol 5-dimensions (EQ-5D)-5L Visual analogue scale, 0-100 mm, the higher the value, the better the health
Anxiety and depressive symptoms Baseline, months 3 and 6 The patient-reported questionnaire Hospital Anxiety and Depression scale goes from 0-21 points, the higher the value, the higher the anxiety and depressive symptoms. In the anxiety and depressive symptoms subscales the points goes from 0-6, the higher the value, the higher anxiety and depressive symptoms respectively
Blood pressure Baseline, month 3 and 6 Resting diastolic and systolic blood pressure
Self-reported disease activity Baseline, months 3 and 6 The patient-reported questionnaire Systemic Lupus Erythematosus Activity Questionnaire includes three parts. The part about disease symptoms goes from 0-47 points, the higher the points the more disease symptoms. Further there is a question about flares with four answer alternatives, from no flares to serious flares. There is also a numerical rating scale about disease activity on a scale from 0-10, the higher value the higher the disease activity
Inflammatory markers Baseline, months 3 and 6 Blood samples are collected before and after maximal ergometercycle exercise test
Fatigue Baseline, months 3 and 6 The patient-reported questionnaire Functional Assessment of Chronic Illness Therapy, FACIT-Fatigue goes from 0-52 points, the higher the value, the less the fatigue
Quality of life in SLE Baseline, months 3 and 6 The patient-reported questionnaire Lupus Quality of life questionnaire goes from 0-100 points, the higher the value the better the quality of life
Generic Quality of life Baseline, months 3 and 6 The patient-reported questionnaire Short Form Health Survey (SF-36). Each subscale goes from 0-100 points, the higher the value, the higher the quality of life.
Quality of life and health status Baseline, months 3 and 6 The patient-reported questionnaire EuroQol 5-dimensions (EQ-5D). The index scores goes from -0,594 till 1,000, the higher the value, the higher the quality of life
Disease activity Baseline, months 3 and 6 SLE Disease Activity Index 2000 (SLEDAI-2K) assessed by a physician, goes from 0-105 points, the higher the value, the higher the disease activity
