Key clinical point: Treatment with biological disease-modifying antirheumatic drugs (bDMARDs) was associated with a significantly lower incidence of psoriatic arthritis (PsA) compared with narrow-band ultraviolet light B (nb-UVB) phototherapy in patients with moderate-to-severe chronic plaque psoriasis.
Major finding: The annual incidence rate for PsA was lower in patients prescribed bDMARDs vs phototherapy (1.20 vs 2.17 cases per 100 patients/year; P = .006). Treatment with bDMARD was associated with a lower risk for incident PsA (adjusted hazard ratio, 0.27; P = .004).
Study details: The data come from a retrospective, nonrandomized study involving 464 patients with moderate-to-severe plaque psoriasis who were prescribed either at least 5 years of bDMARDs (n=234) or at least 3 nb-UVB phototherapy courses (n=230).
