Does arthritis research focus on psoriatic arthritis?
Psoriatic arthritis develops from the skin condition psoriasis and can cause swelling in fingers, fingernails, toes and sometimes the spine. Researchers are looking for causes and better treatments for this type of arthritis. One gene has been linked to psoriatic arthritis and scientists are looking for others. Researchers are now studying whether people with psoriasis, but not arthritis, also have this gene. Drugs that affect the immune system have been shown to be effective in psoriasis, leading researchers to look closer at the role of the immune system in psoriatic arthritis.Does arthritis research focus on rheumatoid arthritis?
