Raynaud's Syndrome: a neglected disease

Area of Science:

• Vascular Medicine
• Rheumatology
• Dermatology

Background:

• Raynaud's Syndrome is a common condition causing digital ischemia.
• It is triggered by cold temperatures or emotional distress.
• Primary Raynaud's is benign, while secondary Raynaud's indicates underlying systemic disease and can cause ischemic lesions.

Purpose of the Study:

• To differentiate between primary and secondary Raynaud's Syndrome.
• To outline diagnostic approaches for both types.
• To review current and emerging treatment strategies.

Main Methods:

• Diagnosis of primary Raynaud's relies on clinical presentation.
• Secondary Raynaud's requires additional investigations like imaging and laboratory tests to identify the underlying condition.
• Treatment involves lifestyle modifications and pharmacological interventions.

Main Results:

• Lifestyle changes include smoking cessation, avoiding cold, and modifying hand use.
• Pharmacological treatments include calcium-channel blockers, prostacyclins, and newer agents, with variable efficacy (often <50%).
• Iloprost, a prostacyclin derivative, shows promise for secondary Raynaud's; other procedures like sympathectomy are largely ineffective.

Conclusions:

• Accurate diagnosis is crucial, distinguishing benign primary Raynaud's from secondary forms linked to systemic illness.
• Current treatments offer symptomatic relief by reducing attack severity and frequency, rather than a cure.
• Iloprost represents a significant advancement in managing secondary Raynaud's Syndrome.
