MOTA, Licia Maria Henrique da et al. 2011 Consensus of the Brazilian Society of Rheumatology for diagnosis and early assessment of rheumatoid arthritis. Rev. Bras. Reumatol. [online]. 2011, vol.51, n.3, pp. 207-219. ISSN 0482-5004. http://dx.doi.org/10.1590/S0482-50042011000300002.
OBJECTIVE: Develop guidelines for management of rheumatoid arthritis (RA) in Brazil, focusing on diagnosis and early assessment of the disease. METHOD: Literature review and expert opinions of RA Committee members of the Brazilian Society of Rheumatology. RESULTS AND CONCLUSIONS: The following ten reccommendations were established: 1) RA diagnosis should be established considering clinical findings and complementary test results; 2) Special attention should be given to the differential diagnosis of arthritis; 3) Rheumatoid factor (RF) is an important diagnostic test, but has limited sensitivity and specificity, mainly in early RA; 4) Anti-CCP (anti-cyclic citrullinated peptide antibody) is a marker with sensitivity similar to that of the RF, but with higher specificity, mainly in the initial phase of disease; 5) Although unspecific, acute-phase reactants should be measured in patients with clinical suspicion of RA; 6) Conventional radiography should be performed for diagnostic and prognostic assessment of the disease. When necessary and available, ultrasound and magnetic resonance may be used; 7) Rheumatoid arthritis classification criteria (ACR/EULAR 2010), although not yet validated, may be used as a guide to aid in diagnosing patients with early RA; 8) One of the combined disease activity indices should be used to assess disease activity; 9) At least one of the functional capacity assessment instruments, such as mHAQ or HAQ-DI, should be regularly used; 10) At the early assessment of the disease, the presence of worse prognostic factors, such as polyarticular involvement, high titers of RF and/or anti-CCP, and early joint erosion, should be investigated.
