Study summary

Post-Infectious Bronchiolitis Obliterans (PIBO) is an irreversible obstructive lung disease characterized by subepithelial inflammation and fibrotic narrowing of the bronchioles after lower respiratory tract infection. This disease is diagnosed mainly in children, more frequently before the age of 2 years. Due to symptoms such as dry cough and dyspnea sensation, most of these patients have low levels of physical activity compared to healthy individuals. Physical activity can positively influence oxygen consumption, muscle strength, and quality of life. High levels of oxygen consumption are associated with a lower risk of respiratory disease and hospitalization. High-intensity interval training (HIIT) may be an effective way to improve oxygen consumption, muscle strength, and quality of life in patients with chronic diseases. HIIT has been shown to produce less dyspnea sensation and to be more entertaining in children and adolescents with respiratory disease compared to continuous training. Thus, the investigators propose to perform telematically real-time guided training to reduce travel times and additional costs to patients.

Objective: To analyze the effects of a telematically supervised high-intensity intervallic training program on aerobic fitness, as well as functional/clinical outcomes in patients with PIBO.

Methods: Randomized controlled trial with two groups. Exercise group: 16-week HIIT training conducted telematically; Control group: will follow the routine physician's recommendations. Patients will be recruited at Vall D'Hebrón University Hospital (Barcelona), Niño Jesús University Hospital (Madrid), and Donostia Universitary Hospital (San Sebastián). Criteria for participation: (I) Diagnosis of PIBO; (II) Clinically stable at the time of the assessments; (III) Age between 6 to 20 years old.

Study arms

  • Experimental
    Exercise group

    16 weeks of a "High Intensity Interval Training" exercise program conducted telematically with real time supervision twice a week. The exercise program consists of a circuit of exercises aiming to achieve a target heart rate for each fitness level.

    Other: Exercise group

  • No intervention
    Control group

    Routine physician recommendations for physical activity.

Interventions

  • OtherExercise group

    Participants will perform a 16-week High Intensity Interval Training exercise program, twice a week. The intervention will be conducted telematically with real time supervision.

What researchers measure

Primary outcomes

  1. Change in peak oxygen consumption

    Change in peak oxygen consumption (mL/kg/min) will be evaluated through cardiopulmonary exercise testing (CPET).

    Time frame: Change from baseline to 16 weeks

  2. Change in time to ventilatory threshold

    Change in time to ventilatory threshold (minutes) will be evaluated through cardiopulmonary exercise testing (CPET).

    Time frame: Change from baseline to 16 weeks

  3. Change in percent oxygen consumption at ventilatory threshold

    Change in percent oxygen consumption at ventilatory threshold will be evaluated through cardiopulmonary exercise testing (CPET).

    Time frame: Change from baseline to 16 weeks

  4. Change in ventilatory efficiency

    Change in ventilatory efficiency will be evaluated by combining ventilation (VE) and carbon dioxide production (VCO2) measurements to report VE/VCO2 ratio, evaluated through cardiopulmonary exercise testing (CPET).

    Time frame: Change from baseline to 16 weeks

Secondary outcomes

  1. Change in forced expiratory volume in the first second

    Change in forced expiratory volume in the first second (liters) will be evaluated through spirometry.

    Time frame: Change from baseline to 16 weeks

  2. Change in forced vital capacity

    Change in forced vital capacity (liters) will be evaluated through spirometry.

    Time frame: Change from baseline to 16 weeks

  3. Change in forced expiratory flow between 25 and 75% of forced vital capacity

    Change in forced expiratory flow between 25 and 75% of forced vital capacity (liters/minute) will be evaluated through spirometry.

    Time frame: Change from baseline to 16 weeks

  4. Change in muscle strength

    Changes in muscle strength will be evaluated using a dynamometer.

    Time frame: Change from baseline to 16 weeks

  5. Change in lower body strength

    Changes in lower body strength will be evaluated using the 30 seconds Sit to Stand Test (30STS).

    Time frame: Change from baseline to 16 weeks

  6. Change in free fat mass

    Changes in free fat mass (percent) will be evaluated through bioimpedance.

    Time frame: Change from baseline to 16 weeks

  7. Change in lean mass

    Changes in lean mass (percent) will be evaluated through bioimpedance.

    Time frame: Change from baseline to 16 weeks

  8. Change in hip-waist ratio

    Changes in hip-waist ratio will be evaluated by combining hip circumference and waist circumference measurements using a non-stretchable tape measure.

    Time frame: Change from baseline to 16 weeks

  9. Change in body mass index

    Changes in body mass index will be evaluated by combining weight and height measurements to report BMI (kg/m\^2).

    Time frame: Change from baseline to 16 weeks

  10. Change in quality of life

    Changes in quality of life will be evaluated through the Saint George's Respiratory Questionnaire (SRQ). The overall result of the scale is a numerical value from 0 to 100, with the highest values corresponding to a worse quality of life.

    Time frame: Change from baseline to 16 weeks

  11. Change in dyspnea

    Changes in dyspnea will be evaluated through the Medical Research Council (mMRC) modified dyspnea scale. The overall result of the scale is a numerical value from 0 to 4, where the highest value corresponds to the worse dyspnea.

    Time frame: Change from baseline to 16 weeks

Other outcomes

  1. Height in meters

    Height will be evaluated using a stadiometer.

    Time frame: Change from baseline to 16 weeks

  3. Daily physical activity level

    Daily physical activity level will be evaluated through the physical activity questionnaire (PAQ). The overall test score is from 1 to 5 points, with a higher score indicating a higher level of activity.

    Time frame: Change from baseline to 16 weeks
