High prevalence of psoriatic arthritis in patients with severe psoriasis with suboptimal performance of screening questionnaires
Annals of Rheumatic Diseases, 07/06/2012
Haroon M et al. – 29% of Psoriasis (Ps) patients attending dermatology clinics had undiagnosed psoriatic arthritis (PsA). Psoriasis severity was associated with a new diagnosis of PsA. Poor sensitivities for the screening questionnaires were noted due to inadequate detection of patterns of arthritis other than polyarticular disease.
