Management of Raynaud's Phenomenon

Introduction to Referral Guidelines

• The American College of Rheumatology recommends that patients with suspected secondary Raynaud's, particularly those with red flag features like digital ulceration, severe painful episodes, or systemic symptoms, should be referred promptly to a rheumatologist for evaluation and management 1, 2

Conditions Requiring Rheumatology Referral

• Patients with secondary Raynaud's phenomenon, such as those with systemic sclerosis, systemic lupus erythematosus, or rheumatoid arthritis, require rheumatology evaluation and management 1, 2, 3
• The presence of red flag features, including severe painful episodes, digital ulceration, systemic symptoms, or constitutional symptoms, warrants immediate rheumatology referral 1, 2, 3

Urgency of Referral

• Immediate rheumatology referral is indicated for patients with digital ulcers, signs of critical ischemia, gangrene, or suspected early diffuse cutaneous systemic sclerosis or interstitial lung disease 2, 3

Diagnostic Considerations

• The European League Against Rheumatism recommends performing laboratory testing, including ANA, rheumatoid factor, anti-CCP, and ESR/CRP, when secondary causes of Raynaud's phenomenon are suspected 4

Treatment Considerations

• The American College of Cardiology recommends the use of calcium channel blockers, such as nifedipine, as first-line therapy for Raynaud's phenomenon, with consideration of second-line agents, including phosphodiesterase-5 inhibitors, prostacyclin analogs, and endothelin receptor antagonists, for patients with inadequate response to first-line therapy 1
