Which autoimmune disorder is closely associated with the onset of Raynaud's phenomenon?

Raynaud's phenomenon happens when digital arteries overreact to cold or stress, causing a characteristic color change from white to blue to red. In autoimmune diseases, this is usually due to immune-mediated vascular dysfunction and endothelial injury that make the small vessels hyperreactive. Systemic lupus erythematosus often features vascular involvement, including vasospastic responses in the digits. The immune abnormalities in SLE—immune complex–driven inflammation and endothelial dysfunction—can lead to secondary Raynaud's phenomenon. Because this vascular involvement is relatively common in SLE, Raynaud's can be seen as an early or prominent manifestation in some patients. While other autoimmune conditions can also have Raynaud's, the association with SLE is well recognized in exams and clinical practice, reflecting its frequent vascular component. Management focuses on protecting the digits from cold, avoiding triggers, and using vasodilator therapy (like calcium channel blockers) if symptoms are troublesome, along with confirming the autoimmune diagnosis and monitoring disease activity.
