Brief Summary

Axial spondyloarthritis (axSpA) is a chronic inflammatory immune disorder with a global prevalence that ranges from 20 to 160 cases per 10000 individuals. axSpA has two forms of clinical presentation (radiographic and non-radiographic) based on the presence or absence of radiographic sacroiliitis. This condition mostly affects the vertebral spine, and is characterized by joint pain and stiffness, fatigue, and restricted function, which leads to a substantial physical, psychological, and socioeconomic burden. The clinical management of axSpA needs to combine pharmacological and non-pharmacological approaches to reduce inflammation and improve health-related quality of life. The aim of the study will be to determine if a 12-week probiotic supplementation will be more effective than an online-delivered strength training program at improving functional capacity in adults with non-radiographic axSpA. As a secondary aim, we will compare the impact of both interventions on disease activity, spinal mobility, quality of life and biochemical measures. This will be the first randomized controlled trial where probiotics are compared with an active intervention.

Conditions

Arthritis; Rheumatic Diseases; Autoimmune Diseases

Outcome Measures

Primary Outcomes (1)

• The primary outcome will be functional disability during daily life activities, evaluated with the Bath Ankylosing Spondylitis Functional Index.

  The Bath Ankylosing Spondylitis Functional Index includes 10 items (scale of 0 to 10, higher scores denoting worse performance), and is among the recommended core set of instruments for axSpA.

  Change from Baseline BASFI at 4 and 12 weeks

Secondary Outcomes (4)

• The secondary outcome will be disease activity during daily life activities, evaluated with the Bath Ankylosing Spondylitis Disease Activity Index.

  Change from Baseline BASDAI at 4 and 12 weeks

• Spinal mobility will be measured with the Bath Ankylosing Spondylitis Metrology Index (BASMI)

  Change from Baseline BASMI at 4 and 12 weeks

• The Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) 30 will be used to determine health-related quality of life

  Change from Baseline ASQoL at 4 and 12 weeks

• Biochemical measures (interleukin-1 (IL-1) and tumor necrosis factor a (TNFa))

  Change from Baseline biochemical measures at 4 and 12 weeks

Study Arms (2)

Probiotic group

EXPERIMENTAL

Participants in the probiotics group will receive probiotic supplementation for 12 weeks.

Dietary Supplement: Probiotic group

Exercise group

ACTIVE COMPARATOR

The control group will undergo a 12-week online-delivered Tabata program, as a form of high-intensity interval training.

Other: Exercise group

Interventions

Probiotic group DIETARY_SUPPLEMENT

During the first 4 weeks, patients will be instructed to take two capsules of Enterelle plus (Bromatech lab, Manno, Switzerland) during morning time, before or after breakfast. Enterelle plus contains specific strains, i.e., S boulardi, E faecium, and acidophilus, that contribute to reduce the mycotic flora and modulate the gastrointestinal transit. For the next 8 weeks, participants will be told to ingest two capsules of Adomelle (Bromatech lab, Manno, Switzerland) at night, during or right after dinner. Adomelle contains several strains, including Bifidobacterium breve, that help to reduce abdominal fat, pain, and gas, and control the frequency of deposition

Probiotic group

Exercise group OTHER

This type of intervention has shown to benefit patients with several chronic conditions 23, including axSpA 13. Exercises combined high knees, lunges, basic burpees, plank, skipping, mountain climbers, and squats with jumps. The training routine will be conducted three times per week, and each session will last around 8 minutes (2 sets of 4 minutes, with a 10 second rest between them). All sessions will be individually tailored and supervised by a senior professional with a degree in Physiotherapy and Sciences of Physical Activity and Sport. Overall, participants will be told to continue exercising if low to moderate bearable pain appeared during training.
