Demographic, clinical, and angiographic data of patients with Takayasu arteritis in Brazil

We collected clinical, demographic, and angiographic data of Takayasu arteritis (TA) patients followed at Rheumatology Division of three Public University Centers (UNIFESP, USP, and UNICAMP) located in São Paulo State, Brazil. Clinical and demographic data were obtained from 73 patients (61 female; 50 white) The mean age at time of diagnosis was 27 y.o. and the mean follow-up time was 5 years. The following clinical features were observed along the evolution of these patients: absent or reduced pulses in upper limbs (85%), arterial bruit (64.5%), claudication of upper members (57%), headache (45%), hypertension (35.5%), dizziness (29%), cardiac bruit (29%), weight loss (27.5%), arthralgia or arthritis (26%), fever (24.5%) and claudication of lower limbs (20.5%). According to new angiographic classification of Takayasu arteritis performed in 28 patients followed at UNTFESP, with routine full aortography, 21% were classified as type I, 4% as type IIa, 4% as type III, 14% as type IV and 57% as type V. No patients had type IIb. Patients with Takayasu arteritis in Sao Paulo State Brazil showed female predominance and arterial involvement pattern similar to the one observed in Japan, with more than 20% classified as type I with exclusive involvement of the branches from the aortic arch.
