Topic Area


Raynaud’s phenomenon mainly affects women between 20 and 40 years of age. In a high percentage of cases ranging between 50% and 90%, this phenomenon is primitive; in such cases it is not necessary to make specific therapies, but only a symptomatic treatment and protection against cold and other triggering factors. In such cases the capillaroscopic finding is almost completely normal, in some cases it may sometimes be observed slight dilation of the loops with erythrocyte aggregation phenomena. Recent studies have shown that performing ENA indiscriminately to all patients with Raynaud’s phenomenon may be inappropriate
