简要总结
Polymyalgia rheumatica (PMR) is prevalent among elderly. Untreated, it leads to major reduction in quality of life. Glucocorticoids are the cornerstone of treatment, but have drawbacks, warranting glucocorticoid sparing treatment. A proof of concept study on Rituximab (RTX) vs placebo showed efficacy in 48 vs 21%(p=0.049) in glucocorticoid free remission after 21 weeks (Marsman et al. 2021). Though promising, the short study duration and small sample size require further confirmation. Therefore a larger randomised controlled trial with longer follow up will be performed on RTX efficacy on glucocorticoid free remission in newly diagnosed PMR patients during glucocorticoid taper.
