5. Study Description

Brief Summary
Inflamed joints in patients with rheumatoid arthritis and psoriatic arthritis are characterized by low oxygen levels and inflammation. We propose to investigate whether tiny bubbles (nanobubbles) when given in a drink can alter oxygen level in joints. These nanobubbles are so small that they can enter the bloodstream when given as a drink. This information will give new information on the role of oxygen in joint inflammation and could possibly lead to new treatment approaches in the future.
