title: [Current opinion on diagnosis of primary Sjögren's syndrome].
abstract: For many years, Sjögren's syndrome was a purely descriptive diagnosis of symptoms such as xerostomia and dry eye (sicca syndrome). The different classification criteria proposed for Sjögren's syndrome comprise a rather variable spectrum of diagnostic possibilities, at one extreme of which we find an array of exclusively objective parameters while, at the other extreme, the objective parameters and patients' symptoms balance out. Improved accuracy in the diagnosis of Sjögren's syndrome can be attained only through the combination of a symptoms questionnaire, histopathology, scintigraphy or sialography or evaluation of the unstimulated salivary flow and specific autoantibodies. In these last few years, further methods have been proposed to increase diagnostic accuracy: the analysis of various salivary constituents, saliva and tear ferning tests, the search for new autoantigens and, above all the use of ultrasonography and magnetic resonance imaging. Color-power Doppler and magnetic resonance sialography have recently been proposed as promising techniques to improve sensitivity and diagnostic specificity. This study discusses the data present in the literature and personal experience regarding diagnostic methods in a group of 350 patients affected by primary Sjögren's syndrome.
