RA Window Advantages

Decent Essays

Advances in the treatment of RA have shown that active drugs should be given as soon as possible [1, 2]. This idea has been framed in the concept of a window of opportunity for the best results, window that extends only for the first months since symptoms onset [3-6]. The benefits of treatment in this window include increased response rates, decreased disease activity, prevention of bone erosions, less disability, increased rates of remission, even of drug-free remission, and larger improvement in health quality scores [3-6]. These benefits are of large significance, but are demanding for the rheumatologist because often it is difficult to diagnose RA when the first symptoms appear. This task has been facilitated by the development of new RA classification criteria in 2010 [2]. These criteria aim to define patients earlier in the disease course than the 1987 ACR criteria [7].
