Is it possible to discontinue glucocorticoids in rheumatoid arthritis with the use of synthetic disease-modifying antirheumatic drugs?

| Summary: | The aim of the work is to study the possibility of glucocorticoid (GC) discontinuation or their target dose achievement in patients (pts) with rheumatoid arthritis (RA) receiving conventional synthetic disease-modifying antirheumatic drugs (DMARDs).
Materials and methods. 270 pts with RA (women – 86.6 %) aged 51.2 ± 0.71 years, with a disease duration of 50.20 ± 3.82 months were examined. Rheumatoid factor was found in 64.8 % of individuals, anti-cyclic citrullinated peptide (ACCP) antibodies – in 66.6 %. DMARD therapy included methotrexate (n = 91), leflunomide (n = 95), sulfasalazine (n = 51), hydroxychloroquine (n = 3) or its combination (n = 126). The SPSS (version 22.0) software was used for the statistical analysis.
Results. During the 3-year study, GC was withdrawn in 33 % of pts in the period from 3 to 30 months (mostly in the first 6 moths). Among those who continued to take GC, the target dose (<7.5 mg/d) was achieved only in 32.6 % of pts. Among pts continuously receiving GC, compared with pts who discontinued GC therapy, there were significantly more women (89.5 % vs. 80.8 %), ACCP-positive pts (88.4 % vs. 55.0 %), with higher DAS-ESR values (5.29 ± 0.10 vs. 4.84 ± 0.15) and more pronounced structural changes on the SHS scale (43.40 ± 2.42 vs. 32.40 ± 2.71).
According to the logistic regression analysis, female sex (OR 2.39), elderly pts (OR 1.02), ACCP-positivity (OR 3.73), disease activity by DAS-ESR (OR 1.19) and structural joint changes (OR 1.01) were significantly associated with the risk of continuing GC treatment. Only the initial dose of GC ≥7.5 mg/d was associated with the inability to reach the target dose of GC during the entire follow-up period (OR 6.32).
Conclusions. Despite of the treatment with conventional synthetic DMARD, only a third of RA pts can withdraw GC, mostly in the first 6 months. For the pts who continue taking GC, the target dose can be achieved in 33 % of them. Independent predictors of the impossibility to withdraw GC are female sex, old age, ACCP-positivity, higher RA activity according to DAS-ESR and more pronounced joint destruction in early stages. An initial GC dose ≥7.5 mg/d is a negative prognostic factor in achieving the target dose. |
