Objectives: Anti-drug antibodies (ADA) are responsible for decreased adalimumab efficacy in axial spondyloarthritis (SpA). We aimed to evaluate the ability of methotrexate (MTX) to decrease adalimumab immunisation.
Methods: A total of 110 patients eligible to receive adalimumab 40 mg subcutaneously (s.
Objective: To assess the implementation of European recommendations for use of TNF inhibitors for spondyloarthritis (SpA), rheumatologists' level of knowledge of and adherence to the recommendations, and potential barriers to the application of recommendations.
Methods: We conducted a retrospective study among 42 rheumatologists who initiated a first subcutaneous TNF inhibitor for SpA in 2013 or 2014. Thirty items from national and international recommendations were separated into 3 domains: indication, pretherapeutic monitoring, and management under TNF inhibitors.
