Age at psoriasis onset may influence the risk of developing PsA. Cheemalavagu and colleagues aimed to identify clinical factors associated with PsA development in patients with psoriasis. Using data from a registry that included 384 patients diagnosed with PsA either after or concurrently with their psoriasis diagnosis, they demonstrated that patients with psoriasis onset at the age of 42.6 vs 18.9 years had a 62% shorter time interval between psoriasis and PsA diagnoses and were ~4.6 times more likely to have a concurrent onset of PsA within 6 months of having psoriasis. Thus, older age at onset of psoriasis may indicate a higher risk of developing PsA. This result is consistent with the observation that psoriasis patients carrying the human leukocyte antigen (HLA) C*06:02 allele (associated with early-onset psoriasis) are at lower risk of developing PsA.
Most patients with PsA have psoriasis vulgaris. The differential risk of PsA with different psoriasis phenotypes is less well studied. Therefore, Gershater and colleagues conducted a population-based retrospective cohort study that included patients with psoriasis vulgaris (n = 35,281), pustulosis palmoplantaris (n = 9639), or generalized pustular psoriasis (n = 2281), and who were propensity score–matched with an equal number of control individuals without psoriasis. They demonstrated that compared with control individuals without psoriasis, patients with psoriasis vulgaris had the highest risk for incident PsA (hazard ratio [HR] 87.7), followed by those with generalized pustular psoriasis (HR 26.8) and pustulosis palmoplantaris (HR 15.3). Thus, the study confirms the highest risk for PsA with psoriasis vulgaris, as well as the estimated risk for other, less common forms of psoriasis.
Finally, a cross-sectional study by Toledano and colleagues showed that PsA patients with a sedentary lifestyle (<90 min of physical activity per week) had more enthesitis, fatigue, pain, higher disease activity, greater disease impact, and lower functionality compared with those having a nonsedentary lifestyle. The study indicates that PsA patients would benefit from >90 minutes of physical activity per week.
