Background. There is a time sensitive window of opportunity in rheumatoid arthritis (RA) in which therapeutic intervention is more effective, the disease being more susceptible to the immunomodulatory effects of the remissive medication. The goal is to prevent osteo-articular damage, which causes severe functional deficit, and to raise the chance to lead the disease in remission. Evolution towards RA represents a multi-step process. In other medical fields prevention has the same important role as treatment, so could we in the future switch again the therapeutic paradigm in RA, from early treatment to prevention of RA, by treating patients with high risk of developing disease? Initiating treatment in the pre-RA phases could potentially lead to a better immune modulation or even preventing disease development by acting on less mature pathogenic processes. Treating in the initial symptomatic phase of the disease could potentially be more effective in reducing disease persistence and the development of structural lesions. The clinically suspect arthralgia (CSA) definition offers a support of clinical parameters for future longitudinal studies, where together with para clinical parameters, laboratory studies and imagistic studies, could lead to the development of imminent RA classification criteria. Currently there are more ongoing studies that have the primary objective to prove this concept with different subpopulations and treatments, but most of them have inclusion criteria based on the presence of autoantibodies. The publication of this trials results in the next decade will help to better understand the efficacy of therapeutic intervention with the scope of preventing chronic arthritis and what subset of patients at risk to treat. There are no recommendations for management of CSA, but current practice is symptomatic treatment with nonsteroidal anti-inflammatory drugs, pain relievers and of course monitoring.
Clinically suspect arthralgia – are we going towards a new shift in the therapeutic paradigm of rheumatoid arthritis?
