| Popis: | BACKGROUND: Treatment modifications, including dose-escalations, dose-reductions, switches, discontinuations and restarts of biologics may be necessary in the management of psoriasis but the patterns of usage are incompletely defined.OBJECTIVES: To examine the treatment utilisation patterns of adalimumab, etanercept and ustekinumab among biologic-naïve and non-naïve psoriasis patients enrolled in the British Association of Dermatologists Biologic Interventions Register (BADBIR).METHOD: The cohort study included adults with chronic plaque psoriasis who were followed-up for ≥12-months.Treatment modifications were assessed during the first year of therapy. The time-trend method, comparing the cumulative dose (CD) patients received to the recommended cumulative dose (RCD), was used to assess dosing patterns. Concomitant use of other systemic treatments was also examined.RESULTS: In total, 2980 patients (adalimumab:1675; etanercept:996; ustekinumab:309) were included; 79.2% were biologic-naïve. Over 12-months, 77.4% of patients continued the biologic, 2.6% restarted therapy after a break of ≥90-days, 2.5% discontinued, and 17.5% switched biologic therapy. Most patients (85.7%) received the RCD of the biologic, although 8.1% were exposed to a higher CD. In total, 749(25.1%) patients used conventional systemic therapies concomitantly with a biologic at some stage; methotrexate was used most commonly (458;61.2%). Of those using combination therapy, 454(60.6%) continued the use of the conventional systemic therapy for >120 days after the start of the biologic.CONCLUSION: More than one-third of patients experienced treatment modifications within the first year of initiating a biologic. Conventional systemic therapies, particularly methotrexate, were commonly used concurrently which should be considered when evaluating treatment response and adverse events to biologics in real-world observational studies.
