Systemic scleroderma and Raynaud's can cause painful ulcers on the fingers or toes, which are known as digital ulcers. (Also see What is Scleroderma?, Types of Scleroderma, Digital Ulcers, and Raynaud's)
But remember, no treatment for finger ulcers should be undertaken without the supervision of a physician — it's very important to treat finger ulcers properly, to prevent complications such as serious infection, gangrene or possible amputation.
Elucidating the burden of recurrent and chronic digital ulcers (DU) in systemic sclerosis (SSc): long-term results from the DUO Registry. SSc-associated DUs based on the occurrence of DUs over time may help to identify patients in the clinic with a heavier DU burden who could benefit from more complex management to improve their functioning and quality of life. Ann Rheum Dis, 11/26/2015.
Dysfunctional arteriovenous anastomoses (AVAs) in hands of systemic sclerosis (SSc) patients with digital ulcers (DU). In SSc patients with DU there is a dysfunction of the AVAs of the finger pulp and AVA dysfunction may be a part of autonomic dysfunction in SSc. PubMed, Clin Exp Rheumatol, 05/21/2014.

The association of antiphospholipid antibodies (APLA) with cardiopulmonary manifestations of systemic sclerosis. APLA is associated with pulmonary arterial hypertension (PH), interstitial lung disease, Raynaud's phenomenon and digital ulcers, so endothelial abnormalities and small vessel thrombosis may be important in the pathogenesis of these disease features. PubMed, Clin Exp Rheumatol, 02/24/2014. (Also see Antiphospholipid Syndrome, Causes of Pulmonary Hypertension, and Raynaud's)
Increased intrarenal arterial stiffness may predict the occurrence of new digital ulcers (DU) in systemic sclerosis. Doppler indices could be used in association with the capillaroscopic and clinical findings or serological tests for the identification of patients at high risk of developing DUs.

Macitentan is also known as Opsumit by Actelion. It is a dual endothelin receptor antagonist that was submitted for FDA approval for use in pulmonary hypertension in December 2012.Clinical Trial: Macitentan for the Treatment of Digital Ulcers in Systemic Sclerosis Patients (DUAL-2). The primary objective is to demonstrate the effect of macitentan on the reduction of the number of new digital ulcers in patients with systemic sclerosis and ongoing digital ulcers (DU). ClinicalTrials.gov. 12/18/12. (Also see Scleroderma Clinical Trials)
Stress-related changes to immune cells in the skin prior to wounding may impair subsequent healing. These studies show the first preliminary evidence that the number and activation of immune cells in the skin prior to wounding are affected by stress and can impact healing. PubMed, Brain Behav Immun, 2015 Nov;50:47-51. (Also see Emotional Adjustment)
