Clinical Trial: Physical Training in Patients With Relapsing Polychondritis
Study Status: Recruiting
Recruit Status: Recruiting
Study Type: Interventional
Official Title: Physical Training in Patients With Relapsing Polychondritis
Brief Summary: Physical training may improve physical capacity and health parameters in various systemic autoimmune diseases. Therefore, the present study will assess the role of an exercise training program in patients with relapsing polychondritis.
Detailed Summary: Impact of physical training in patients with relapsing polychondritis.
Sponsor: University of Sao Paulo
Current Primary Outcome: Cardiopulmonary test [ Time Frame: 12 weeks ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Strength muscle tests [ Time Frame: 12 weeks ]The dynamic 1-RM for the leg-press and the bench-press exercises, arm curl (with the dominant arm), and isometric strength (assessed by handgrip, with the dominant arm) will be assessed at baseline and after the intervention.
- Healthy Assessment Questionnaire (HAQ) [ Time Frame: 12 weeks ]Especific questionnaire to assess the quality of life. Pontuaction: 0.00-3.00
- Functional muscle tests [ Time Frame: 12 weeks ]Muscle function will be evaluated through the TUG and the TST tests
- Muscle biopsy [ Time Frame: 12 weeks ]After local anesthesia, a cutaneous incision will be made in lateral thigh face. The biopsy will be done using the Bergstrom needle. Histological (hematoxylin and eosin)/immunohistochemical (CD4, CD8, CD68, CD20, C5b-9, MHCI, MHCII, CD31) analysis will be performed in muscle samples (at baseline and after 12 weeks) in all patients (present study)
