Summary
Brief summary
Gout is a chronic inflammatory arthritis. This study aims to see if krill oil ( a natural anti-inflammatory therapy) can reduce inflammation in people with gout, as well as the current standard of care, colchicine.
People with gout, and evidence of inflammation on ultrasound will be randomized to either krill oil or colchicine for 12 weeks, and then return for a follow-up ultrasound to see if the ultrasound detected inflammation has decreased, increased or unchanged. WE will also look to see what effects krill oil has on pain, quality of life, global health, blood test of inflammation and the number of flares of gout.
