Although results from this study indicated that having a first-degree relative with psoriasis should be disregarded as an exclusion criterion for psoriatic juvenile idiopathic arthritis, this information should still be used an inclusion criterion for the classification of the condition.
Researchers studied data for 99 patients classified with juvenile psoriatic arthritis (JPsA) and 144 patients with unclassified juvenile idiopathic arthritis (JIA). Investigators reviewed patients’ demographics, history, physical examinations and laboratory features available at time of enrollment and at 6-month follow-up that were relevant to the International League of Associations for Rheumatology classification criteria for JIA.
Results showed the most common reason for patients being unclassified was having a first-degree relative with psoriasis (FRP), noting that 57 patients would have been classified if FRP was not used as an exclusion criterion. Investigators noted FRP was a necessary criterion of inclusion in order to classify 11 children out of 77 with JPsA. ‒ by Monica Jaramillo
