[Leg ulcer in mixed connective tissue disease. Resolution during sitaxsentan therapy]. / Unterschenkelulzera bei Sharp-Syndrom. Abheilung unter Sitaxentan.

ABSTRACT

Leg ulcers may result in serious morbidity in patients with connective tissue diseases and Raynaud's phenomenon (RP). We describe a 35-year-old woman with mixed connective tissue disease who suffered from leg ulcers refractory to iloprost. When the patient was treated with the selective endothelin A receptor antagonist sitaxsentan for pulmonary arterial hypertension, the ulcers improved within 4 weeks and resolved completely thereafter. In addition, severity of RP ameliorated markedly. Further evaluation of sitaxsentan in patients with connective tissue diseases suffering from ischemic skin ulcers is required.
