Researchers of a study found that individuals diagnosed with psoriasis (PsO) at age 43 or older are more likely to experience a shorter interval between PsO and psoriatic arthritis (PsA) diagnoses. They are also more likely to have concurrent diagnoses compared to younger individuals. The study, utilizing data from a tertiary care psoriatic disease biorepository, aimed to identify clinical and demographic factors associated with a shorter interval between PsO and PsA diagnoses.

The study enrolled 577 patients in the PsA registry, with 384 having PsA diagnosed after or concurrently with PsO. Advanced age at PsO onset was significantly associated with a shorter interval to PsA diagnosis, with patients diagnosed with PsO at age 42.6 years having a 62% shorter interval compared to those diagnosed at age 18.9 years. Additionally, patients with a BMI of 34 had a 10% shorter interval between PsO and PsA compared to those with a BMI of 26, nearing statistical significance. The study suggests that older age at PsO onset is linked to a shorter interval to PsA development and concurrent PsA diagnosis, emphasizing the need for targeted screening and referral practices to improve health outcomes for patients with psoriatic disease.
