Scleroderma is a rare, long-term autoimmune disease in which normal tissue is replaced with dense, thick fibrous tissue. Normally, the immune system helps defend the body against disease and infection. In people with scleroderma, the immune system triggers fibroblast cells to produce too much of the protein collagen. The extra collagen becomes deposited in the skin and organs, causing hardening and thickening that is similar to the scarring process. Although scleroderma most often affects the skin, it also can affect other parts of the body, including the lungs, and in its most severe forms scleroderma can be life-threatening. Scleroderma-related interstitial lung disease is one example of a life-threatening scleroderma condition. In people with symptomatic scleroderma-related interstitial lung disease, scarring occurs in the delicate lung tissue, compromising lung function. The purpose of this study is to determine whether people with symptomatic scleroderma-related interstitial lung disease experience more respiratory benefits from treatment with a 2-year course of mycophenolate mofetil or treatment with a 1-year course of oral cyclophosphamide.
This study will evaluate the effect of treprostinil diethanolamine (UT-15C) sustained release tablets(compared to placebo) on digital ulcers in patients with scleroderma. Treprostinil diethanolamine is an analog of prostacyclin. Prostacyclin is a naturally occuring substance produced by the cells of blood vessels that inhibits platelet aggregation, induces vasodilation, and suppresses smooth muscle proliferation. Improvement in blood flow in lower limbs and fingers would be anticipated to result in a reduction in ischemic pain, Raynaud's phenomenon and promote healing of digital ulcers and other ischemic wounds.
The purpose of this study was to evaluate the safety of Dasatininb in the treatment of scleroderma pulmonary interstitial fibrosis.
Scleroderma, or systemic sclerosis, is a chronic connective tissue disease generally classified as one of the autoimmune rheumatic diseases. The disease is characterized by thickening and fibrosis skin, affecting vessels and many organs such as the esophagus, stomach, bowls, lung, heart and kidney. The exact cause or causes of scleroderma are still unknown, but scientists and medical investigators in a wide variety of fields are working hard to make those determinations. It is known that scleroderma involves overproduction of collagen. FLICKMAN et al, in 1973 published an article about the role of lidocaine at prolyl-hydroxylase activity decrease, which is an important enzyme of collagen production. Until now, there is only a case series showing the improvement of thickening skin (75%) and esophagus symptoms (66%) after intravenous lidocaine 2% during 10 days. So it is necessary a RCT to prove these findings.
To determine sleep disturbance, pulmonary function test, 6 minute walk, echocardiogram abnormality, arterial blood gas, ventilation/perfusion scan of the chest in Scleroderma patient with Pulmonary Hypertension.
This study is to compare the ability of optical biopsy. Research can use light enters the skin, collected, analyzed by the computer, and a picture created for the pathologist to conventional histologic examination compare with the pathologist looking at the piece of tissue through a microscope makes the diagnosis.
It is difficult to predict how a women with an autoimmune disease will do during pregnancy. Some women will improve, others will worsen. Some pregnancies progress normally and others become very complicated. The Duke Autoimmunity in Pregnancy (DAP) Registry will enroll women with autoimmune diseases, such as lupus, rheumatoid arthritis, scleroderma, and Sjogren's syndrome who wish to become, or already are, pregnant. We will follow these women throughout pregnancy to better understand how their autoimmune disease affects their pregnancy, and vice versa.
Systemic Sclerosis (Scleroderma) varies greatly in clinical manifestations, mode of presentation, and course. The natural history of this chronic autoimmune disease ranges from benign to fatal. Patients are classified into limited and diffuse scleroderma defined by the degree of skin involvement. Patients with limited disease (e.g. the C.R.E.S.T. syndrome) generally have mild disease and normal survival. However, patients with diffuse cutaneous scleroderma often have severe multi-system disease that is not only devastating emotionally and physically but is associated with a 60-70% five year survival and a 40-50% 10 year survival. No therapies have proven effective in the treatment of scleroderma. Strategy to treat scleroderma have included attempts to prevent fibrosis with drugs that interfere with collagen metabolism, attempts to modify the disease process by immunosuppression and attempts to alter the disease by vasoactive drugs. High dose of corticosteroids and other immunosuppressive drugs (e.g. chlorambucil, 5-fluorouracil, methotrexate, cyclophosphamide, cyclosporine) used at conventional doses have not proven curative, but have shown some benefit for inflammatory features of the disease (e.g. arthritis, myositis, fibrosing alveolitis). Both allogeneic and autologous bone marrow transplantation (BMT) have shown to modify and in some instances reverse a variety of animal models of autoimmune disease. This has prompted many investigators to propose the use of peripheral blood stem cell transplantation (PBSCT) for the treatment of autoimmune disease including scleroderma. Unfortunately, this approach risks infusing untreated autoreactive lymphocyte clones after the immunoablative preparative regimen. We have previously demonstrated that high-dose cyclophosphamide without BMT can induce durable and complete remissions in another autoimmune disease, severe aplastic anemia. Recent data with high dose cyclophosphamide show that it can induce complete remissions in other autoimmune hematologic disorders. The objective of this study is to determine whether high dose cyclophosphamide can induce a durable remission in scleroderma patients with life-threatening disease, and to determine toxicity of high dose cyclophosphamide in high risk scleroderma patients.
Raynaud's phenomenon is thought to occur when, in response to cold or emotional stress, there is closure of the digital arteries and cutaneous arterioles leading to the clinical finding of sharp demarcated digital pallor and cyanosis of the distal skin of the fingers and/or toes. Patients often continue to experience problems despite current available treatment. The investigators' study will investigate the use of a new vasodilator called Fasudil, a Rho-kinase inhibitor. The investigators' hypothesis is that Fasudil will prevent vasoconstriction of digital and cutaneous arteries during a standard laboratory based cold exposure and will therefore improve digital blood flow and skin temperature recovery time following cold challenge. These data will provide the rationale for a more elaborate clinical trials in real life situations.
