  • Title: [Primary and secondary Raynaud's phenomenon].
    Author: Distler JH.
    Journal: Z Rheumatol; 2008 May; 67(3):211-7; quiz 218-9. PubMed ID: 18437399.
    Abstract:
    The term Raynaud's phenomenon describes an abnormal vasospastic response to cold or emotional stress. It is a common condition with a prevalence of 3-5% of the population. Clinically, Raynaud's phenomenon manifests as sharply demarcated colour changes of the skin of the digits that is often accompanied by paraesthesia. Raynaud's phenomenon can be subdivided into primary, or idiopathic, and secondary forms, in the latter of which associated diseases or causes can be identified. The pathogenesis of the disease is incompletely understood. Pathologic changes have been observed primarily in vascular smooth muscle cells, endothelial cells and perineuronal microvasculature. Current therapeutic strategies include supportive treatments, topical therapeutic approaches and systemic medication. Drug therapies with proven efficacy include calcium channel blockers, prostacyclin analogues, fluoxetine, losartan and sildenafil.
