Spondyloarthritis is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. The classification axial spondyloarthritis is adopted when the spine and/or the sacroiliac joints are predominantly involved. This version of recommendations replaces the previous guidelines published in May 2013. A systematic literature review was performed, and two hundred thirty-seven studies were selected and used to formulate 29 recommendations answering 15 clinical questions, which were divided into four sections: diagnosis, non-pharmacological therapy, conventional drug therapy and biological therapy. For each recommendation the level of evidence supporting (highest available), the strength grade according to Oxford, and the degree of expert agreement (inter-rater reliability) is informed. These guidelines bring evidence-based information on clinical management of axial SpA patients, including, diagnosis, treatment, and prognosis. The purpose of these guidelines is to bring evidencebased information on clinical management of axial SpA patients, including, diagnosis, treatment and prognosis, for rheumatologists, general physicians, allied-specialists (dermatology, ophthalmology and gastroenterology), and other allied-professionals, such as physiotherapists. This version replaces the previous guidelines published on May 26, 2013 [3] and should be updated every 4 years. Methods A systematic literature review was performed, with external review of an specialized group of the Brazilian

This is the first study evaluating SIJ MRI in patients with rAAU without back symptoms, showing positive findings for sacroiliitis. Moreover, a BME score ≥ 3 had better performance to define an SIJ MRI as positive for axSpA.

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.

Psoriatic arthritis (PsA) is a chronic and systemic immune disease characterized by inflammation of peripheral and/or axial joints and entheses in patients with psoriasis (PsO). Extra-articular and extracutaneous manifestations and numerous comorbidities can also be present. These recommendations replace the previous version published in May 2013. A systematic review of the literature retrieved 191 articles that were used to formulate 12 recommendations in response to 12 clinical questions, divided into 4 sections: diagnosis, non-pharmacological treatment, conventional drug therapy and biologic therapy. These guidelines provide evidence-based information on the clinical management for PsA patients. For each recommendation, the level of evidence (highest available), degree of strength (Oxford) and degree of expert agreement (interrater reliability) are reported.
