Title: Spondyloarthropathies and Psoriatic Arthritis – Clinical Aspects and Treatment Poster II
Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose:
Both EULAR (European League Against Rheumatism) and GRAPPA (Group for Research and Assessment of Psoriasis and Psoriatic Arthritis) recently published treatment guidelines for Psoriatic Arthritis (PsA). Despite them, it remains unclear how physicians approach the management of PsA since there are few studies in the real world.
The purpose of the study was to describe treatment patterns (treatment discontinuation, switches, and therapy add-ons) for PsA patients in a real-world setting.
Methods:
A Retrospective descriptive study was performed in a university hospital with its own health insurance and captive population. All patients fulfilling Classification Criteria for Psoriatic Arthritis (CASPAR) with at least 3 visits of follow-up were included. Electronic medical records were reviewed between 01/01/2000 and 05/31/2017.
Results:
A total of 275 patients with PsA were included, with a median follow-up of 5.3 years (IQR: 2.1-10.2). Demographical data can be found in Table 1.
First line treatment were NSAIDs in 9.45% of the patients, traditional DMARD (tDMARD) in 88%, being methotrexate the most frequent one (76%), and biologic DMARDs (bDMARD) in 2.18%. None received combination of tDMARDs. Reasons for switching or discontinuation were: lack of response 41%, adverse events 35%, remission 12% and suspension by the patient 12%.
bDMARD were used in 29.5% of the patients. As monotherapy in 55.4 % of the cases, and combined with methotrexate and leflunomide in 38.5 % and 6% respectively.
Survival rate of DMARDs at the end of follow up was 40% for tDMARD and 72% for bDMARD.
Additional information on both tDMARD and bDMARD can be found in Table 2.
At end of follow up mean DAS28 was 3.1 (SD: 1.4), mean HAQ: 0.42 (SD: 0.6), and 51% of patients fulfilled Minimal Disease Activity (MDA) criteria.
Conclusion:
In this real-world data, 40% of the patients continued with the first tDMARD after 5 years of follow up and only one third of patients required bDMARD. Drug survival was very good both for tDMARDs and bDMARDs.
