Abstract:
Objective:Treat-to-target strategies for psoriatic arthritis (PsA) have been proposed for several years, however, the status of target and goal achievement in China is unknown. Therefore, we aimed to investigate the target achievement of PsA patients, and differences of treatment goals were further analyzed.Methods:A total of 360 PsA patients from Peking University First Hospital PsA patient cohort (PKUPsA) between January 2016 and March 2024 were included. We retrospectively analyzed the disease activity of patients at their enrollment. Minimal disease activity (MDA), disease activity index for PsA (DAPSA), clinical DAPSA (cDAPSA) and disease activity score based on 28 joint counts (DAS28) were evaluated. Interclass correlation coefficient (ICC) was used to test the consistency of all these assessments.Results:Three hundred and sixty patients were included in this study, with 149 females (41.4%), median age 47 (36, 57) years and duration of PsA for 2.0(1.0, 6.8) years. 129 (35.8%) patients reported family history of PsO. The most common comorbidities were hyperlipidemia (101, 28.1%) and hypertension (78, 21.7%). There were 217 (60.3%), 75 (20.8%) and 18 (5.0%) patients treated with conventional synthetic DMARDs, biologics and JAK inhibitors respectively. Forty-nine (13.6%) patients ever received intra-articular injection of glucocorticoid. Based on the different definitions, the rates of target achievement were 33.9% (MDA), 56.1% (DAPSA), 60.8% (DAS28-ESR), 63.9% (DAS28-CRP) and 64.2% (cDAPSA). The main limiting factors for MDA attainment among those who had achieved DAPSA or DAS-defined targets were pain VAS, Psoriasis Area and Severity Index (PASI), tender/swollen joint count, patient global assessment, HAQ, and number of enthesitis, based on leeds Enthesitis Index(LEI). The ICCs of these evaluation methods were 0.489~0.819 ( P<0.001). The consistency was the best between DAPSA and cDAPSA, medium between DAS28-CRP and DAS28-ESR, and worst between MDA and DAS28-CRP. Moreover, DAPSA was more consistent with DAS28 than cDASPA. MDA showed moderate consistency with all other assessments. Conclusion:33.9%~64.2% of PsA patients achieved targets based on different definitions. MDA was the most stringent target, while cDAPSA was the most loose one. In general, MDA was not well consistent with other assessments.
