Analysis by Age Group of Disease Outcomes in Patients with Psoriatic Arthritis: A Cross-Sectional Multicentre Study
Elderly psoriatic arthritis (PsA) patients may show greater inflammatory activity and worse prognoses than patients of other ages. However, these patients may be at risk of receiving fewer systemic treatments. In this report, we have analysed disease outcomes in PsA by age groups.
This cross-sectional, multicentre study included 227 PsA patients under biological and non-biological systemic therapies. The study population was divided into four categories by age: < 40, 40‒49, 50‒65 and > 65 years. Physical functioning, disease activity, remission rates and disease impact were compared.
Thirty-one patients (13.7%) were under 40 years, 26.9% (n = 61) were 40–49 years, 26.4% (n = 60) were 50–65 years and 33.0% (n = 75) were patients > 65 years. Compared with the other age groups, disease duration was significantly higher in subjects older than 65 years (p < 0.001). Only 8% of patients older than 65 years received corticosteroids compared with 29% of patients aged < 40 years, 13.1% of patients aged 40–49 years and 26.7% of patients aged 50–65 years (p = 0.007). Similarly, only 36% of patients over 65 years of age received a biological therapy compared with between 51.6 and 59% for the other age groups (p = 0.036). However, remission rates were not statistically different between groups. Disease-associated physical disability was similar among groups. Compared with patients aged < 40 years, more patients > 65 years achieved low disease impact (10.7% vs 37.7%, respectively; p < 0.05).
Fewer older patients received corticosteroids and biological therapy. However, disease outcomes were similar or even better compared with those observed in younger patients. Therefore, treatment strategies for older patients with PsA should be similar to those offered to younger individuals.
