Overview

Secondary Raynaud's = Raynaud's due to another illness.
This is also known as Raynaud's Phenomenon.

Nailfold capillaroscopy can determine whether or not Raynaud's is secondary to an illness such as scleroderma. Raynaud's is often the first symptom of scleroderma, and may precede the onset of Scleroderma and other scleroderma symptoms by years or by months.

Only 5% to 20% of people with Raynaud's phenomenon subsequently develop scleroderma, but about 90% of scleroderma patients experience this extreme cold sensitivity with red/blue flashes in their hands and feet as a primary manifestation of their disease. What Causes Raynaud's? National Heart Lung and Blood Institute. NIH.

Low Risk for Developing Systemic Sclerosis

Some people with positive ANA and Raynaud's never go on to develop a defined connective tissue disease (CTD).

A 2006 study presented at the American College of Rheumatology meeting showed that there is a subset of patients with positive ANA and Raynaud's who never go on to develop systemic scleroderma.

High Risk Factors for Systemic Sclerosis

Raynaud's + SSc Antibodies + Abnormal Nailfold = 60x Higher Risk of Systemic Sclerosis

Difficulties in diagnosis of systemic sclerosis-related interstitial lung disease (SSc-ILD). The diagnosis of SSc-ILD could maybe be made sooner if a capillaroscopy was performed earlier, according to the current criteria of early SSc. PMC, Respirol Case Rep, 2015 Sep; 3(3): 99–101. (Also see Pulmonary Fibrosis)

Nailfold Capillaroscopy and Other Diseases

Nailfold Capillaroscopy and Other Diseases. Capillaroscopy can also be useful for the diagnosis of secondary Raynaud's due to diseases other than scleroderma, including glaucoma, graft vs. host disease, rheumatoid arthritis, and vascular diseases.

Research on Nailfold Patterns in Systemic Sclerosis

Nailfold capillary abnormalities in erectile dysfunction (ED) of systemic sclerosis (SSc). Neither the presence or absence of abnormal capillaroscopy findings nor the subdivision into early, active and late patterns is associated with coexistent ED in SSc. PubMed,Rheumatology. (Also see Erectile Dysfunction and Scleroderma)

Nailfold capillaroscopy (NFC) abnormalities as predictors of mortality in patients with systemic sclerosis (SSc). Avascular scores higher than 1.5 at NFC was an independent predictor of death in SSc, suggesting that NFC can be useful for predicting SSc outcome. PubMed, Clin Exp Rheumatol.

Vascular Disease and Systemic Sclerosis (SSc, Scleroderma)

Vascular Disease and Systemic Scleroderma. The vascular system is our circulatory system. It consists of all the vessels that carry blood and lymph through the body, to and from organs. Vessels include arteries, veins, and capillaries. Any condition that affects the vascular system, all of in part, is considered a vascular disease. ISN.
