Study Finds that Psoriasis Onset Determines if Psoriatic Arthritis Patients Develop Arthritis or Psoriasis First
American College of Rheumatology (ACR)In a new study presented at the 2019 ACR/ARP Annual Meeting, researchers found that the age of psoriasis onset determines whether arthritis or psoriasis starts first in people with psoriatic arthritis. Additionally, they found that pustular psoriasis is associated with arthritis onset two years earlier than the intercept interval; and there is an increased delay for nail involvement, plaque psoriasis or family history of psoriasis from psoriasis to arthritis by approximately two years for each characteristic.(Abstract #2854).
