A small secret of big rheumatology

Current recommendations for RA treatment determine the need to reduce the dose and duration of glucocorticoid (GC) use. This is due to the wide spectrum and high frequency (up to 100%) of serious adverse events (AE) during GC treatment. However, in real practice GCs in RA are used very often (in Russia, Western Europe and the USA they are used in about 50% of patients), and often in long-term courses. This is explained by the fact that the combination of disease-modifying antirheumatic drugs (DMARDs), including biologics (bDMARDs) and Janus kinase inhibitors (JAK), with GCs allows to achieve faster improvement of patients’ condition and therefore is very “convenient” for many patients and physicians. However, it is very difficult to ensure dose reduction and (especially!) complete discontinuation of GC administration afterwards. Clinical and observational studies show that 30–40% of patients manage to discontinue the use of GCs during treatment with bDMARDs and JAK. In addition, discontinuation of GCs may significantly increase the risk of RA flare, even with complex pathogenetic therapy. Nevertheless, prolonged use of GCs, including low doses (less than 7.5 mg/day of prednisolone) should be considered as an indicator of the severity of the disease course and inadequacy of the current therapy. Therefore, we should strive for personalization of RA therapy, selection of DMARDs based on the assessment of the disease phenotype and predictors of response to treatment with different drugs, achieving the main goal of therapy – remission/low disease activity and achievement of acceptable quality of life, without the use of GCs.
