1, 2 Subsequently, work by Lipsker 3 and de Koning et al 4 as well as the Schnitzler syndrome study group 5 led to a more standardized definition of the syndrome culminating in the development of the Strasbourg criteria for diagnosis (Table 1). The diagnostic criteria of Schnitzler syndrome suggested in 2001 were revised by an expert meeting in Strasbourg and validated in a multicentric study (Lipsker et al 2001, Simon et al 2013, Gusdorf et al 2017). Sensitivity and specificity of the Strasbourg criteria for definite diagnosis were 81% and 100% respectively (Gusdorf et al 2017).
