Background:
Nowadays, numerous therapeutic options are available for patients with rheumatoid arthritis (RA), and the number of patients achieving remission has significantly increased.
However, some patients have a disease defined by EULAR as “difficult-to-treat”(D2T), which today represents a new challenge for rheumatologists.
The primary objective was to evaluate the characteristics of the D2T-RA population recorded in the Italian GISEA registry undergoing treatment with b/tsDMARDs.
The secondary objective was to assess the effectiveness and changes at 6 and 12 months in disease outcomes, stratifying the analysis by different mechanisms of action.
The Globally, the 5-year survival rate was significantly lower for D2T-RA patients compared to those with non-D2T-RA (47.5% vs 62.5%, p<0.001).
No significant differences in persistence were observed among the classes of b/tsDMARDs used in D2T-RA (log-rank test: 6.76, p=0.15), with a 5-year survivarate of 38.7% for abatacept, 41.2% for TNFi, 48.1% for IL6r inhibitors, 62.3% for anti-CD20, and 49.6% for JAK inhibitors.
D2T-RA患者における薬剤の5年継続率は、非D2T-RA患者と比較して低かった(47.5% vs 62.5%)。 5年継続率はアバタセプト38.7%、TNFi41.2%、IL6r阻害薬48.1%、抗CD20薬62.3%、JAK阻害薬49.6%であった。
Conclusion
All currently used b/tsDMARDs appear to be effective in this patient cohort.
The higher efficacy of JAK inhibitors, particularly in managing pain symptoms in these patients, warrants further investigation.
