CLUE Study: Connective Tissue Disease Leg Ulcer Etiology Study
Connective Tissue DiseasesBlood Coagulation Disorders5 moreTo 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.
Multi-center, Web Based Observational Study of Pulmonary Hypertension in Scleroderma Patients
Systemic SclerosisScleroderma2 moreThe purpose of this study is to determine the timeline of progression from pre-pulmonary hypertension to diagnosable pulmonary hypertension based on right heart catheterization. Moreover, to determine the timeline for progression from diagnosable pulmonary hypertension to clinical worsening of disease as defined as death, hospitalization, or worsening of PHT symptoms.
Cell Surface Marker Expression in Autoimmune Diseases
Systemic Lupus ErythematosusSjogren's Syndrome5 moreThis study is designed to explore the expression of cell-surface markers in the following seven disease areas: (a) systemic lupus erythematosus, (b) Sjogren's syndrome, (c) multiple sclerosis, (d) systemic sclerosis, (e) Crohn's disease, (f) ulcerative colitis and (g) inflammatory myositis.
Utility of Breath-holding Test in Systemic Sclerosis
Systemic SclerosisThis study aims to evaluate the utility of breath-holding test as a marker of pulmonary disease severity in patients with systemic sclerosis.
Vasculopathy, Inflammation and Systemic Sclerosis
Systemic SclerosisIt is a study of basic research with mechanistically objectives and including clinical biological samples.
Treatment Outcome in Early Diffuse Cutaneous Systemic Sclerosis
Early Diffuse Cutaneous Systemic SclerosisThe aim of the study is to compare the effectiveness of commonly used immunosuppressant treatments for early diffuse cutaneous systemic sclerosis (SSc).
Obstructive Sleep Apnea in Scleroderma and Pulmonary Involvement
SclerodermaSystemic3 moreScleroderma is an autoimmune disease with skin manifestations and may have pulmonary involvement. Obstructive sleep apnea (OSA) may also be seen in scleroderma. Less is known regarding the prevalence of OSA in scleroderma and its association with pulmonary involvement.
Laser Speckle Contrast Imaging for Cutaneous Microvascular Dysfunction Detection in Systemic Sclerosis....
Raynaud DiseaseScleroderma1 moreThe aim of the study is to determine if postocclusive hyperemia of palmar and dorsal face of the hand with Laser speckle contrast imaging discriminate between patients with systemic sclerosis, subjects with primary Raynaud's phenomenon and healthy subjects.
Soluble VE-cadherin and VE-cadherin Antibody in Sclerodermic Sclerosis
Primary Raynaud DiseaseSystemic SclerosisVe-cadherin is expressed in endothelial cells. Systemic slerosis is a rare auto-immune disease with a endothelial dysfunction. This study is to evaluated the level of soluble VE-cadherin and VE-cadherin antibody in patients with systemic slerosis.
A Non-Interventional Pilot Study Assessing Whether Lysyl Oxidase-like 2 (LOXL2) is Present in Subjects...
Limited SclerodermaDiffuse SclerodermaTo treat patients with scleroderma by blocking the expression of LOXL2. The investigators first need to confirm (through observation) that LOXL2 is overexpressed in disease.
