Summary

This study aims to further evaluate the anti-inflammatory effects of the mTOR inhibitor sirolimus in patients with adult-onset Still's disease (AOSD), and to verify whether it can reduce inflammation and control disease activity by restoring ZFP36L2 expression and promoting the degradation of inflammatory cytokine mRNAs. A total of three patients with refractory AOSD will be enrolled, defined as those showing no significant improvement after treatment with glucocorticoids at 1 mg/kg, or experiencing relapse during tapering of glucocorticoids to 15 mg/day. On the basis of their existing therapy, patients will receive oral sirolimus at a dose of two capsules per day, one in the morning and one in the evening. On the day prior to initiating sirolimus and at weeks 4, 8, and 12 of treatment, 10 ml of peripheral blood will be collected by trained medical staff, and neutrophils will be isolated within 2 hours to assess ZFP36L2 expression levels. Throughout treatment, patients' clinical manifestations, including fever, rash, and joint pain, will be monitored, and dynamic changes in multiple inflammation-related markers will be measured in peripheral blood at weeks 4, 8, and 12. These include C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), serum ferritin, soluble interleukin-2 receptor (sIL-2R), and a panel of cytokines. Finally, correlations among sirolimus treatment, ZFP36L2 expression, inflammatory responses, and disease activity will be analyzed to explore its potential therapeutic mechanisms in AOSD.
