Key clinical point: Compared with the general population, the prevalence of psychotic disorders was significantly lower in patients with psoriatic arthritis (PsA), but a co-diagnosis of PsA and psychotic disorders was associated with an increased mortality rate, that too at a lower age.
Major finding: The prevalence of psychotic disorders was significantly lower in patients with PsA vs the general population (0.61% vs 0.72%; P = .006). Patients with PsA who did vs did not have psychotic disorders had an increased likelihood of death (9.3% vs 4.9%; P = .005) and significantly lower age at death (64.7 years vs 74.5 years; P < .001).
Study details: This cohort study included 449,392 patients with psoriasis and 47,825 patients with PsA.
Disclosures: The lead author Emilie Brenaut declared receiving a postdoctoral fellowship from the French Society of Dermatology and the Collège des Enseignants en Dermatologie de France as well as personal fees and nonfinancial support from various sources. The other authors reported no conflicts of interest.
