Epidemiological studies have informed putative examples of autoimmune links with psoriasis. Up to 30% of patients with cutaneous psoriasis suffer from concomitant psoriatic arthritis,[2] a deforming seronegative arthropathy that may manifest as a polyarthritis, sacroileitis, monoarthritis or arthritis mutilans. It has also been noted that there is an increased prevalence of rheumatoid arthritis,[3] celiac disease[4] and Crohn's disease[5] in patients with psoriasis, and there is general recognition that sufferers of one autoimmune disease are predisposed to others.
