Systemic sclerosis (scleroderma) is an autoimmune connective tissue disease that involves the skin and other internal organs for which there are few effective treatment options. We hypothesize that treatment with abatacept, a new therapy recently approved for the treatment of rheumatoid arthritis, may reduce the progression of skin thickening and fibrosis in people with scleroderma.
This is a research study of an investigational product called Mycophenolate mofetil (MMF). The study is designed to establish the safety and potential benefit of MMF. MMF has proven one of the most effective medications to date for SLE and associated nephritis. It also appears to be active in polymyositis and dermatomyositis. This medication inhibits inosine monophosphate dehydrogenase, the rate-limiting enzyme in synthesis of guanosine nucleotides. It blocks the type II isoform found in activated lymphocytes more potently than the type I isoform inhibiting both T- and B-lymphocytes. In SSc, MMF has been tried after anti-thymocyte globulin in one small open label study with efficacy with a significant improvement in skin score. We will test the safety and efficacy of MMF in SSc. All study patients will receive the study medication. The effect of the study medication will be examined in two subgroups of patients: those with early or progressive skin disease (skin substudy) and those with muscle disease (muscle substudy). The change in modified Rodnan skin score (MRSS) and creatinine phosphokinase (CK) for, respectively, the skin and muscle substudies at 6 months after treatment will be compared to baseline values.
- Systemic sclerosis (scleroderma; SSc) is a rare, disfiguring systemic disorder characterized by fibrosis of the skin and visceral organs that alters every aspect of an individual life - Although some features of scleroderma phenotype are well established and represent the hallmarks of the disease, the primary cause is not fully delineated, though both endothelial cell damage, immunological abnormalities and excessive extracellular matrix production are well-documented - Recently, excessive oxidative stress has been implicated in the pathogenesis of scleroderma - N-acetylcysteine (NAC) exhibits direct and indirect antioxidant properties. Its free thiol group is capable of interacting with the electrophilic groups of ROS. This interaction with ROS leads to intermediate formation of NAC thiol, with NAC disulphide as a major end product. The net result is a decrease of the concentrations of OH-, H2O2, and HOCl. In addition, NAC exerts an indirect antioxidant effect related to its role as a glutathione (GSH) precursor. It serves as a central factor in protecting against internal toxic agents. - In view of these considerations we expect that NAC can confer substantial benefit in patients with scleroderma reducing skin fibrosis in view of its antioxidant properties, and we have decided to conduct a double blind, multicenter trial to establish whether NAC could ameliorate skin fibrosis in scleroderma patients
Progressive systemic sclerosis (SSc) is an immune-based disease that causes abnormal connective tissue growth of the skin and internal organs. At this point, there are no effective therapies for treating SSc. Thalidomide is a medication that has been shown to stimulate an immune response that reduces the body's synthesis of collagen, the main component of connective tissue. This study will determine the effectiveness of thalidomide in treating adults with SSc.
Rituximab 1000 mg i.v. will be given on day 1 and 15, week 26 - 28, together with a corticosteroid regimen consisting of methylprednisolone 100 mg i.v. 30 minutes prior to both infusions.
The Purpose of this study is to determine the response to two different strengths of a topical gel containing nitroglycerin in patients with Raynaud's disease.
The 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.
The purpose of this study is to determine whether the drug Bosentan improves exercise tolerance in scleroderma patients.
The purpose of this trial is to study the proportion of scleroderma patients who suffer from asymptomatic coronary atherosclerosis compared to healthy controls.
