High Dose Intravenous N-Acetylcysteine Versus Iloprost for Early, Rapidly Progressive Diffuse Systemic...
SclerodermaDiffuseSystemic 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

Systemic SclerosisRaynaud PhenomenaThis is a 12 week double-blind randomized placebo controlled trial in which 30 patients with very early SSc, fulfilling the Very Early Diagnosis Of Systemic Sclerosis (VEDOSS) criteria (9) will be randomized in a 2:1 fashion to receive intravenous methylprednisolone or placebo. Three-day treatment courses are given at week 0, week 4 and week 8. The final assessment is at week 12, and patients will be followed up to one year after baseline
SCLERoderma et Adipose-DErived Stroma Cells
Systemic SclerosisSystemic sclerosis (SSc) is an auto-immune orphan disease mainly characterized by an alteration of the microvascular network, and by cutaneous and visceral fibrosis. Hands are frequently affected, as a consequence of ischemic phenomena and cutaneous fibrosis. As a result, patients suffer from everyday disability, with consequences on their occupational activities and social contact, sometimes severely altering their quality of life. To date, no anti-fibrosis treatment has proven effective; existing vasodilation treatments are unfortunately not very effective, and are associated with adverse effects or restrictions. It is consequently of utmost importance that an effective treatment for sclerodermic hands be developed. The injection of adipose autologous tissue is a common practice in plastic surgery, and has been known for over a century. Adipose tissue, originally used to increase volume, is also characterized by trophic properties associated to stromal vascular fraction (SVF), which contain multipotent stem cells, capable of tissue repair. Interestingly, some SVF cells can be angiogenic and anti-inflammatory, which could improve damage seen with SSc. The injection of SVF into the fingers would also make it possible to control the production of the extracellular matrix and to improve the balance between fibrosis and fibrolysis, resulting in an improvement of cutaneous sclerosis The main purpose is to evaluate the efficacy of SVF injections in the fingers of patients suffering from SSc on the Cochin hand functional scale evaluated at 12 months, in comparison to the control group.
Effects of Probiotics on Gastrointestinal Symptoms and on the Immune System in Patients With Systemic...
Systemic SclerosisSclerodermaSystemic sclerosis (SSc) is an autoimmune disease with unknown etiology, which affects especially the gastrointestinal tract, lungs, heart and kidneys. Immunological abnormalities characterized by innate and acquired immune disturbances are associated with the disease development. The present study aims to evaluate the efficacy and safety of probiotics in gastrointestinal symptoms, nutritional status and innate and acquired immune responses, by means of the evaluation of IgA, Treg and Th1, Th2, and Th17 T helper subtypes levels in patients with SSc. In addition the levels of CD4+ T helper Th1, Th2 and Th17 subtypes and Treg levels will be compared to a healthy control group.
Allogeneic Mesenchymal Stem Cells Transplantation for Systemic Sclerosis (SSc)
Systemic SclerosisMesenchymal Stem CellsThis study will explore safety and efficacy of allogeneic mesenchymal stem cells transplantation (MSCT) to treat patients with diagnosis of systemic sclerosis(SSc) who have been resistant to multiple standard treatments. The underlying hypothesis is that the SSc condition is caused by an abnormal immune homeostasis that can be restored by MSCT.
Autologous Fat Grafting in the Treatment of Critical Limb Ischaemia
Critical Limb IschemiaPeripheral Arterial Disease - PAD7 moreCritical Limb Ischaemia (CLI) is a condition characterized by chronic ischemic at-rest pain, ulcers, or gangrene for more than 2 weeks in one or both legs, attributable to objectively proven arterial occlusive disease.CLI is associated with a high risk of lower amputation, diminished quality of life and mortality. Revascularization by either bypass surgery or endovascular recanalization is considered the first-choice treatment in patients with CLI. Revascularization is not always possible because patients with CLI often have severe comorbidities or because it is not technically feasible. On the basis of their well-recognized regenerative and angiogenetic properties, cell therapy with autologous bone marrow-derived mesenchymal stem cells (BMMSCs) has been proposed and tested in different animal models and in some human pathological conditions characterized by peripheral ischemia and wound formation.

Neuropsychiatric Scleroderma Study: Systematic Evaluation of Neuropsychiatric Involvement in Systemic...
Systemic SclerosisSystemic sclerosis is a rare disease with vascular involvement and systemic fibrosis. This disease is usually thought to spare central nervous system. However, neuropsychiatric manifestations like depression and cognitive functions impairment seem to be frequent. Pathophysiology of this neuropsychiatric manifestations is currently unknown. White matter hyperintensities have been reported suggested CNS vascular manifestations in systemic sclerosis. Whether this CNS vascular involvement plays a role in neuropsychiatric manifestations in systemic sclerosis is unknown. The primary objective of this prospective and multicentre study is to assess a link between neuropsychiatric manifestations and CNS involvement in systemic sclerosis. Secondary objectives are to assess the frequency of neuropsychiatric manifestations, to compare central nervous system abnormality between scleroderma patient and healthy subjects. Central nervous system involvement and neuropsychiatric manifestations will be systematically assessed through central nervous system imaging and questionnaires.
Pragmatic Clinical Trials in Scleroderma
SclerodermaSystemic2 moreSystemic Sclerosis (SSc) is an autoimmune connective tissue disease characterized by autoantibodies, fibrosis and microvascular injury and endothelial cell activation that results in vascular damage. Vascular injury induces both innate and acquired immune responses resulting in fibroblast activation and organ fibrosis. SSc may target multiple organs, including: skin, lungs, heart, vascularization, kidneys, the gastrointestinal tract and musculoskeletal structures. Mortality among scleroderma patients is significant, with a 3.5 standardized mortality ratio (SMR) in studies of prevalent cases. This mortality may be increased in the early years of the disease, reaching a SMR of 4 in a multinational inception cohort. In general, treatment strategies target involved organs as early as possible to avoid damage. Many treatment options are available for each manifestation, but evidence with respect to the order of treatment is scarce. Financial costs, the lack of proper outcome measures, difficulty to recruit patients as a rare disease, all prevent the development of new big clinical trials, oppositely to other common diseases such as stroke or cancer. The heterogeneous features of SSc may make trials challenging. The current guidelines available are the British guidelines (2017) , and the updated European League Against Rheumatism (EULAR) guidelines, published in 2017. Management guidelines have some gaps regarding second-line treatment, combinations and there are no proposed algorithms. With the pragmatic trials, the investigators intend to fill the gap between the complicated randomized clinical trials and the observational studies. Using the treatments that have already been proved useful in SSc, in an open-label randomized way and based on some refined expert-made algorithms, will allow the investigators to establish the order in how to use them. Patients will be offered to participate with the collection of their clinical data and, if they give their consent, they will be randomized according to the algorithms. There will be an optional part of the study consisting in the collection of blood samples and skin samples for future research.
