RESUMEN
AIM: To evaluate the performance of four different classification criteria for spondyloarthritis (SpA) in patients with late-onset symptoms and to compare the clinical, laboratory and radiographic outcomes among the patients with symptoms before and after 45 years of age. PATIENTS AND METHODS: A total of 329 patients with SpA were enrolled in this prospective cohort. Patients with psoriatic arthritis, reactive arthritis, colitis associated arthritis and peripheral or undifferentiated SpA were excluded. The remaining individuals were divided into two groups based on their ages at the time of onset of symptoms: from 16 to 45 years of age (adult-onset, A-O) and after 45 years of age (late-onset, L-O). The clinical data were collected, including BASDAI, BASFI, BASMI, mSASSS, ASDAS, as were concomitant diseases and medications, efficacy and safety data. The performance of four SpA classification criteria, including modified New York, ESSG, Amor and ASAS, was evaluated in both groups. p value <.05 was considered as significant. RESULTS: Thirty-two patients (9.72%) had L-O axial SpA. Mean age of diagnosis and symptoms were 57.6 (8.0) years and 7.6 (5.1) years, respectively. L-O patients had statistically worse functional impairment and higher disease activity. However, they had lower radiographic sacroiliac and spine damage (p < .001). CONCLUSION: Our data showed that almost 10% of the patients with SpA had late-onset of symptoms. Moreover, they had higher disease activity, worse physical function and lower spine radiographic damage than A-O SpA patients. Additionally, the ASAS classification criteria had the best performance and might be used in clinical practice.

OBJECTIVE: We evaluated the incidence of and the main risk factors associated with cutaneous adverse events in patients with chronic inflammatory arthritis following anti-TNF-α therapy. METHODS: A total of 257 patients with active arthritis who were taking TNF-α blockers, including 158 patients with rheumatoid arthritis, 87 with ankylosing spondylitis and 12 with psoriatic arthritis, were enrolled in a 5-year prospective analysis. Patients with overlapping or other rheumatic diseases were excluded. Anthropometric, socioeconomic, demographic and clinical data were evaluated, including the Disease Activity Score-28, Bath Ankylosing Spondylitis Disease Activity Index and Psoriasis Area Severity Index. Skin conditions were evaluated by two dermatology experts, and in doubtful cases, skin lesion biopsies were performed. Associations between adverse cutaneous events and clinical, demographic and epidemiological variables were determined using the chi-square test, and logistic regression analyses were performed to identify risk factors. The significance level was set at p<0.05. RESULTS: After 60 months of follow-up, 71 adverse events (73.85/1000 patient-years) were observed, of which allergic and immune-mediated phenomena were the most frequent events, followed by infectious conditions involving bacterial (47.1%), parasitic (23.5%), fungal (20.6%) and viral (8.8%) agents. CONCLUSION: The skin is significantly affected by adverse reactions resulting from the use of TNF-α blockers, and the main risk factors for cutaneous events were advanced age, female sex, a diagnosis of rheumatoid arthritis, disease activity and the use of infliximab.

BACKGROUND: Vessel wall inflammation, atherosclerosis and hypercoagulability may be responsible for ischemic events in Takayasu arteritis (TA). No study has evaluated the effect of antiplatelet therapy for the prevention of ischemic events in TA. METHODS AND RESULTS: Forty-eight patients who met the ACR Classification Criteria for TA under follow-up at the Vasculitis Unit of Universidade Federal de São Paulo were evaluated retrospectively for clinical manifestations, therapy and arterial ischemic events. The mean age at study was 38.0 years and the mean age at TA diagnosis was 29.1 years. Women comprised for 89.6% of patients and 60.4% were Caucasian. Risk factors for cardiovascular disease were found in 44 patients (91.7%) The most common comorbidities for TA patients were hypertension (77.1%), high low-density lipoprotein (45.8%) and obesity (16.7%). Antiplatelet therapy was used by 62.5% of patients whereas anticoagulants were used by 12.5%. Acute ischemic events occurred in 29.2% of patients. TA patients with ischemic events used significantly less antiplatelet agents (14.3%) than those without ischemic events (82.4%), P<0.0001. No difference concerning ischemic events was observed in patients on anticoagulant therapy (P=0.339). The 3 deaths of TA patients were observed only in those who had presented ischemic events (P=0.021). Antiplatelet agents had a protective effect against ischemic events (hazard ratio =0.055, 95% confidence interval: 0.06-0.514; P=0.011). CONCLUSIONS: Antiplatelet therapy is associated with a lower frequency of ischemic events in patients with TA.
