Filter by: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.
This is a research study of an investigational drug called ambrisentan (Letairis) in the treatment and prevention of digital ulcers in patients with systemic sclerosis.
Purpose of the study is to evaluate the effectiveness and safety of a new investigational dur, IC351. Study is designed to gather information regarding the possible usefulness of IC351 as a treatment of several blood vessel features of scleroderma. This includes Raynaud phenomenon as well as the vaginal dryness and discomfort associated with scleroderma
A two-stage prospective observational cohort study in scleroderma patients to evaluate screening tests and the incidence of pulmonary arterial hypertension and pulmonary hypertension
Relaxin is a naturally occurring protein prduced by the ovary or placenta in pregnancy. It has ani-fibrotic properties. Previous studies have shown that relaxin is safe at concentrations upto 60 times higher than achieved in pregnancy. Study is designed to see if skin improvement and improvement in functional ability can be achieved.
Systemic sclerodermia is a connectivity characterized by multiple visceral impairments, in particular pulmonary, which can lead to the development of a Pulmonary Arterial Hypertension (PAHT). In one hand, this PAHT is an evolutionary turn in symptomatology and prognosis, and on the other hand, the tracking and the analysis of its effects on the right ventricular function are difficult with the conventional techniques. So, the analysis of the right ventricular function appears capital, because: - it is recognized like an essential determinant of the symptoms and effort capacity, - its prevalence, physiopathology and prognostic values remain unknown in this pathology, - its interest in the starting of the treatment remains to be specified. The aim of this trial is to identify in a population of 150 patients presenting a systemic scleroderma without PAHT: - the incidence of a right ventricular dysfonction, evaluated by the analysis of the myocardic regional function with myocardial tissular Doppler mode, - the physiopathology of this damage by correlation with the tests of respiratory function and the not invasive hemodynamic datas at rest and exercise. - the prognosis value of the abnormalities of the right ventricular function by a follow-up of these patients over a 5 years period. This trial should allowed to define the place of the new right ventricular function markers in the evaluation of the functional consequences, the forecast and perhaps the care of systemic sclerodermic patients.
The purpose of this study is to determine if a reduced intensity (RI) (non-myeloablative) chemoimmunotherapy followed by Allogeneic Stem Cell Transplantation AlloSCT (matched family donors and matched unrelated cord blood donors) will be well tolerated.
We propose to examine several angiogenic/angiostatic mediators in the skin and serum of subjects with SSc and compare it to levels found in the skin and serum of healthy subjects.
This study is to determine if subjects with .systemic sclerosis have stimulatory autoantibodies to the PDGF receptor and to confirm activation (phosphorylation) of the PDGF receptor in skin sites with varying degrees of skin thickening
Systemic scleroderma (SSc) is a rare chronic inflammatory diseae of the connective tissue involving the skin and internal organs. To date there is no proven therapy for the skin fibrosis available. A number of case reports and small uncontrolled cohort studies suggest that UVA1 therapy may improve skin fibrosis. The aim of this study is therefore to investigate whether treatment UVA1 in deed is effective in treating skin fibrosis in SSc using a randomized, intraindividual half body irradiation protocol.
