Psoriatic arthritis (PsA) is an inflammatory disease in which the immune system “attacks” the joints and skin. PsA affects less than 1% of the general population, and it is estimated that up to one-third of the 1 million Canadians living with psoriasis also suffer from PsA^1,2. Moreover, PsA affects men and women equally, in both proportion and presentation of disease. If left untreated, PsA may lead to lasting complications, namely irreversible damage to joints.
