Charlton R, et al. - This study was performed to ascertain the risk of uveitis and inflammatory bowel disease (IBD) in patients with psoriatic arthritis (PsA) when compared to the general population and patients with psoriasis. When a cohort of patients with PsA was compared with the general population and psoriasis controls, substantial risks of uveitis and/or Crohn’s disease was noted, but not of ulcerative colitis.
