Protocolo diagnóstico de la poliartritis crónica

Abstract

Polyarthritis is defined as the presence of synovitis in four or more joints for a period greater than six weeks. To diagnose it, a good case history and physical examination as well as conducting additional tests are essential. As part of this process, it is important to make a differential diagnosis between the different causes of polyarthritis such as inflammatory connective tissue diseases, microcrystalline arthritis, reactive or infectious arthritis, as well as some non-rheumatologic diseases such as paraneoplastic syndromes.
