Raynaud’s phenomenon is caused by episodic vasospasm and ischaemia of the extremities, particularly the digits, in response to cold or emotional stimuli
Attacks comprise a colour change in extremities from white (ischaemia), to blue (deoxygenation), and then to red (reperfusion)
Primary Raynaud’s phenomenon is an exaggerated response to stimuli, with no known underlying cause
Secondary Raynaud’s phenomenon is usually caused by connective tissue disease and patients are more likely to develop tissue damage
Nifedipine is currently the only drug licensed for use in Raynaud’s phenomenon
Key areas of ongoing research include a topical nitroglycerin and a rho kinase inhibitor (vasodilator)
Raynaud’s phenomenon is caused by episodic vasospasm and ischaemia of the extremities in response to cold or emotional stimuli, which result in a characteristic triphasic colour change in extremities—usually fingers or toes—from white, to blue, to red. Raynaud’s phenomenon may be primary, in direct response to stimuli, or secondary to an underlying condition. In 10-20% of cases it may be the first presentation of, or may precede the onset of, a connective tissue disease (such as scleroderma or mixed connective tissue disease), so that underlying causes must be ruled out.
Sources and selection criteria
We searched the Cochrane Library and PubMed (2001-11) using the term “Raynaud’s”. Recommendations made at the May 2011 conference “Raynaud’s phenomenon: new insights, new treatments” organised by the vascular medicine section of the Royal Society of Medicine were reviewed. We also consulted published guidelines and information from the European League Against Rheumatism, Raynaud’s and Scleroderma Association, and Arthritis Research UK.
Raynaud’s phenomenon is triggered by a change in temperature rather than simply exposure to cold. Patients can have attacks throughout the year—for example, if they move from a warm environment to an air conditioned one, stand in a cold wind (even on a relatively warm day), or hold a cold …
