These recommendations are the result of a working group organized at the department of Rheumatology of the Papardo hospital of Messina, with the subsequent involvement of the rheumatology chair of the University of Palermo, the Sicilian rheumatologists specialists and the board of directors of the Italian College of Rheumatologists. The same president of the College has collaborated in the drafting of an editorial on the topic, which will be published in the Italian Journal of Clinical Rheumatology.
