Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are identified from a database of patients with spondyloarthritis and invited to participate. Subjects are randomised using random number generation by Clinical trials manager at BLIS technologies. Assessment and enrolment are performed by blinded assessor who allocates the coded probiotic. Codes are held by clinical trials manager who is not involved in the assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
We propose a trial of a potential treatment for Spondyloarthritis - a common form of arthritis in New Zealand which particularly affects young adults. We will use a probiotic agent (a culture of healthy bacteria) which can modify the bacterial environment in the human intestinal tract. We have previously demonstrated a disturbed bowel bacterial flora in patients with spondyloarthritis, who are known to have an inflamed ‘leaky gut’. By using a probiotic we hope to reverse the inflammatory process in the gut and improve the resulting arthritis. This is a novel approach, using a product developed by a local biotechnology company, which is a safe and potentially effective therapy.
