Abstract

Abstract : Background: Patients with psoriatic arthritis (PsA) present with heterogeneous clinical phenotypes, which includes different clinical manifestations such as peripheral arthritis, axial disease, dactylitis, enthesitis, and skin and nail psoriasis. Many drugs for treatment of PsA are available for individualised treatment strategies but robust evidence is available for peripheral arthritis only as primary endpoint of RCTs. Objectives: To evaluate perception of German physicians on the value of current PsA treatments on different clinical PsA manifestations. Methods: In a face-to-face meeting, 8 German physicians (dermatology, rheumatology), specialised in PsA research/patient care, proposed initial scores for the effect size of current PsA drugs on different PsA manifestations based on knowledge of study data and personal experience in use of the drugs. The ability to achieve a consensus of the proposed efficacy scores was explored by applying an online survey among a cohort of PsA experienced physicians. Finally, a second online survey evaluated how a larger group of physicians personally estimate the drug effect sizes on different PsA manifestations. Results: Table 1 summarises the efficacy scores proposed by the initial expert group. In the first online survey 25 treating physicians were invited to participate, 14 (56%) of whom completed the survey. An agreement rate of over 65% of the participants was archived for 49 (68%) of the 72 proposed efficacy scores (Table 1 ). The consensus was especially high for the group of biological disease-modifying antirheumatic drugs (bDMARDs), except for etanercept and abatacept. However, the second survey (16 (39%) participants out of 41 invited physicians) revealed that the experience with the treatment using abatacept was low (4 / 16 (25%)) or non-existing (3 /16 (18.8%)) and several manifestations could not be estimated (Figure 1 ). Distribution of answers were broad for etanercept in general and for particular drug-manifestation combinations (e.g. effect of ustekinumab on axial disease). Conclusion: Many treatments are available to be used in PsA. The usage of treatment classes seems to depend on experience level and mode of action. Higher agreement on efficacy in specific diseases manifestation was achieved in the class of biologics whereas the opinion on efficacy of csDMARDs in general is divergent. Strategies are needed to guide physicians with lower level of experience in the use of specific drugs to achieve an optimised patient care level using personalized treatment strategies.
