Brief Summary: The effect of bosentan on digital ulcers DU was studied in two randomized placebo-controlled trials RAPIDS-1 and RAPIDS-2 A limitation of these studies was the heterogeneous study population More importantly there were no endpoints that assessed changes in vasculopathy and or perfusion Laser Doppler imaging has been shown to effectively demonstrate blood flow restrictions in the hands of patients with Systemic Sclerosis SSc The relation between blood flow restriction in the hands measured by laser Doppler imaging and the extent of DU disease has not been studied The current study will attempt to demonstrate this relation In addition the impact of bosentan on the blood flow in the hands in a defined cohort of SSc-DU patients with a history of DU within the past 2 years and a clinically relevant reduction of blood flow in the hands will be assessed
