Key clinical point: A previous diagnosis of gout, uveitis, metabolic and lifestyle factors like obesity, alcohol consumption, and infections like pharyngitis and skin infections were potential risk factors for psoriatic arthritis (PsA), whereas statin use showed a negative association with PsA.
Major finding: A previous diagnosis of gout (odds ratio [OR], 2.19), uveitis (OR, 3.79), alcohol use (OR, 1.67), obesity (OR, 1.64), pharyngitis (OR, 1.23), and skin infection (OR, 1.37; all P < .001) were significant risk factors for PsA. The use of statin was negatively associated with PsA (OR, 0.53; P < .001).
Study details: This was a set of 4 separate case-control studies conducted in parallel and included cases of incident PsA (n=7,594), psoriasis (n=111,375), rheumatoid arthritis (RA; n=28,341), and ankylosing spondylitis (AS; n=3,253) matched to control participants (PsA, n=75,930; psoriasis, n=1113,345; RA, n=283,226; and AS, n=32,530).
Disclosures: This work was supported by grants from the National Institute of Health and internal grants from the University of Pennsylvania. Dr. Gelfand, Dr. Love, and Dr. Ogdie declared receiving research grants, honoraria, and reimbursement from and/or serving as a consultant for various sources.
