Official Title: Connective Tissue Disease Leg Ulcer Etiology Study
Brief Summary: To explore the hypothesis that leg ulcers are associated with hypercoagulable states, the CLUE study will evaluate patients with connective tissue disease associated leg ulcers, to identify risk factors (especially hypercoagulability and immunologic characteristics), characterize pathogenesis, predict response to therapy, and assess the impact of lower extremity ulcers on quality of life.
