The problem of difficult-to-treat rheumatoid arthritis in real clinical practice

Abstract
Difficult-to-treat rheumatoid arthritis (D2T RA) represents a complex clinical problem characterized by inefficacy of standard therapy and high disease burden. Despite the implementation of treat-to-target strategies and widespread use of biological (bDMARDs) and targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs), a significant proportion of patients fail to achieve remission or low disease activity, necessitating the definition of the D2T RA category. The working group established by the European Alliance for the Treatment of Rheumatic Diseases (EULAR) proposed a clear definition of D2T RA, including three mandatory criteria: inefficacy of several bDMARDs/tsDMARDs, presence of signs of active or progressive disease, and other circumstances complicating treatment. The prevalence of D2T RA ranges from 5% to 20%, with two-thirds of patients failing to achieve adequate control, and 40% developing drug resistance. Phenotypic heterogeneity of D2T RA manifests in various subgroups: those with inadequate treatment adherence, those with comorbidities, and those with persistent inflammation. Effective management requires a comprehensive approach, including optimization of comorbid conditions, lifestyle modification, and social support. A key challenge remains early identification of patients with D2T RA to enable timely personalized therapy.
