RESUMO
O tratamento das doenças autoimunes sofreu grande avanço nos últimos anos. A artrite reumatoide, de etiologia desconhecida, porém com uma desregulação do sistema imunológico relacionada à sua eclosão e evolução, é hoje passível de tratamento, visando à remissão tanto clínica quanto das lesões estruturais. Além dos anti-inflamatórios e analgésicos utilizados para alívio dos sintomas, várias outras drogas, rotuladas de modificadoras do curso da doença (DMCDs), que visam controlar este distúrbio imunológico expresso pela atividade de diversos mediadores inflamatórios, estão contribuindo para a melhoria da qualidade de vida e do prognóstico dos pacientes.
Autoimmune diseases, as rheumatoid arthritis (RA) had a strong development in their treatment last years. Over the past years, the knowledge about the pathophysiological mechanism of RA has advanced dramatically, with the development of new classes of drugs and the implementation of different strategies of treatment and follow-up. Beside this new drugs, the associated use of the anti-inflammatory drugs, corticoids, sintetic or traditionals disease-modifying antirheumatic drugs allow control or suppress the disease activity giving a better quality of life and prognosis to the patients.

OBJECTIVES: To analyse demographic and clinical variables in patients with disease onset before and after 40, 45 and 50 years in a large series of Brazilian SpA patients. METHODS: A common protocol of investigation was prospectively applied to 1424 SpA patients in 29 centres distributed through the main geographical regions in Brazil. The mean age at disease onset was 28.56 ± 12.34 years, with 259 patients (18.2%) referring disease onset after 40 years, 151 (10.6%) after 45 years and 81 (5.8%) after 50 years. Clinical and demographic variables and disease indices (BASDAI, BASFI, BASRI, MASES, ASQoL) were investigated. Ankylosing spondylitis was the most frequent disease (66.3%), followed by psoriatic arthritis (18%), undifferentiated SpA (6.7%), reactive arthritis (5.5%), and enteropathic arthritis (3.5%). RESULTS: Comparing the groups according to age of disease onset, those patients with later onset presented statistical association with female gender, peripheral arthritis, dactylitis, nail involvement and psoriasis, as well as negative statistical association with inflammatory low back pain, alternating buttock pain, radiographic sacroiliitis, hip involvement, positive familial history, HLA-B27 and uveitis. BASDAI, BASFI and quality of life, as well as physicians and patient's global assessment, were similar in all the groups. Radiographic indices showed worse results in the younger age groups. CONCLUSIONS: There are two different clinical patterns in SpA defined by age at disease onset: one with predominance of axial symptoms in the group with disease onset ≤ 40 years and another favouring the peripheral manifestations in those with later disease onset.
