Arthritis in psoriasis not as common as we once thought

Until a recent release of a meta-analysis, it was assumed that the prevalence of psoriatic arthritis (PsA) ranged between 5% and 42%. After compiling over 250 studies regarding the frequency of this complication, it was found that the estimated prevalence is closer to 20%, indicating that PsA is not as common as once believed. “Investigators observed decreasing proportion estimates as study population sizes increased.” Authors of this meta-analysis encourage physicians to screen patients with psoriasis for psoriatic arthritis.
