Ultrasound of Enthesis in Patients With Ankylosing Spondylitis: a Comparative Study With Health Subjects

* Evaluate the correlation of ultrasound MASEI index with clinical, functional, radiographic and laboratorial variables in patients with ankylosing spondylitis. * Evaluate correlation between articular (shoulders, hips, knees and ankles) ultrasound (synovitis, erosions, power doppler) with same variables. * Evaluate correlation between articular and enthesis ultrasound exam in this study. * Compare patients and healthy individuals data, to calculate the ROC curve to estimate predictor value of disease.
