Additionally, at this early stage, many patients may not meet the criteria for diagnosis but have features that predict a high risk of disease progression to RA. However, data on disease-modifying antirheumatic drug (DMARD) use in the first 3 months are limited. Based on these findings, many clinicians advocate starting therapy (methotrexate preferred) by the 3-month mark of initial symptoms of RA. 14,15 Experts guide their initial treatment recommendations based on time from diagnosis, or more stringently, on time from initial symptoms.ДЇrom a pathophysiology perspective, synovial cytokine patterns (inflammatory mediators) differ at the 4-month mark of initial symptoms of RA, 16 which are thought to be important in the response to therapy. The American College of Rheumatology (ACR) uses a duration of fewer than 6 months of symptoms of disease 13 other organizations have advocated for a later cut off of up to 2 years after diagnosis. Expert group definitions range from defining early RA at the onset of when symptoms develop to when early RA is diagnosed by a clinician.

No consensus exists on the definition of early RA. Definitions of Early RA and Challenges With the Definitions 12 Patients with high disease activity have increased risk of cardiovascular disease that contributes to higher mortality risk. 11 The life span of patients with RA is 3 to 12 years less than that of the general population. Over 35 percent of patients with RA have work disability after 10 years. 10 Burden of DiseaseДisability associated with RA is significant. 7-9 Additionally, researchers using animal model studies are investigating the microbiome effect on RA disease risk. 6 Environmental risk factors associated with RA, though not well understood, include smoking, low socioeconomic status, and viral and bacterial infections.

5 Epigenetics, through the integration of environmental and genetic factors, also contributes to the pathogenesis of RA. 4 Genome-wide association studies have characterized over 100 loci associated with RA risk, most involving immune mechanisms. 3 Rates of RA development are increased in monozygotic twins, implicating genetics as a contributing factor. 3 Women who have not given birth may also be at greater risk of developing RA. Obesity and smoking increase the risk of RA. Multiple environmental and genetic factors contribute to the development of RA. 3 Incidence of RA is 2 to 3 times higher in women.

2 Onset of RA can begin at any age but increases with age onset is highest at 60 years. The average annual incidence of RA in the United States is approximately 70 per 100,000 annually. 1 RA causes inflammation of the synovial lining of joints, leads to progressive erosion of bone (in most cases to irreversible damage to the joint), loss of function, and disability. Rheumatoid arthritis (RA), an autoimmune systemic inflammatory arthritis condition, affects 1 percent of the world's population, including more than 1 million American adults.
