Filter by:The purpose of this study is to look at whether bortezomib, mycophenolate or the combination of both is better to treat scarring of the lung caused by Systemic Sclerosis.
Esophagus is commonly affected in Systemic Sclerosis (SSc) and esophageal function is compromised in about 75% of patients. Previous studies have shown that buspirone, an orally available 5-HT1A (serotonin 1a) receptor agonist, enhances esophageal motility in healthy volunteers. Recently, the investigators observed that a single dose of buspirone (10mg) improves lower esophageal sphincter (LES) function in patients with SSc and esophageal involvement . Objectives: To evaluate the effect of continuous administration of buspirone on esophageal dysfunction and related symptoms in SSc using high resolution manometry (HRM).
The purpose of this study is to determine whether pl-vegf165 (Neovasculgen) is effective in the treatment of digital ulcers related to secondary Raynaud's phenomenon associated with systemic scleroderma
1:1 active treatment: placebo, blinded trial, evaluating the effect of a 4-week treatment period with topical C-82 on skin expression of two gene biomarker surrogates (THBS1 and COMP) for the modified Rodnan skin score (MRSS). Study subjects will be randomized to apply the active study medication daily for 4 weeks to either the right or left forearm and placebo to the contralateral forearm.
Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package- the Transthoracic Parametric Doppler (TPD) (Echosense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS (Lung Doppler Signals) signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.
The aim of the study is to compare the effectiveness of commonly used immunosuppressant treatments for early diffuse cutaneous systemic sclerosis (SSc).
Systemic sclerosis (SSc, also known as scleroderma) is a disease characterized by fibrosis of the skin and organs, inflammation, and an abnormal endothelial cell lining inside of vessels. A common and deadly complication of SSc is pulmonary hypertension (PH), which is an abnormal elevation in the blood pressure within the lung blood vessels. Early identification and treatment of PH is important in SSc, and no clinical factors can predict which patients will develop PH with acceptable accuracy. A potential marker of PH in SSc is the presence of increased amounts of endothelial microparticles (EMPs), which are substances circulating in the blood that were released from damaged vessel wall endothelial lining. A main goal of this study is to investigate if there is a difference in EMP levels between SSc patients with and without PH. The investigators will also use human endothelial cells in a lab environment to test whether these EMPs isolated from SSc patients are actually causing damage to the vessel lining. Lastly, the investigators will investigate the potential benefit of a medication used after transplant, mycophenolate mofetil (MMF). This will be done by causing damage to isolated human endothelial cells and treating them with MMF. The main goal of this portion of our study is to see if EMP levels are reduced when cells are treated with MMF. Overall, the investigators anticipate the following outcomes of this study: 1) use EMP levels to differentiation patients with SSc who have PH from those without PH, 2) use EMPs to understand how endothelial damage occurs in SSc, and 3) use EMPs to help us develop new treatments for patients with vascular diseases.
This registry study will assess the safety and performance of the Celution Device in the processing of an autologous graft consisting of adipose derived regenerative cells (ADRCs) in the treatment of hand scleroderma.
Systemic 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.
Currently investigators do not have diagnostic and prognostic markers for SSc which almost always starts with a vascular disease (Raynaud's disease) isolated for several years. The primary purpose is to highlight discriminating metabolic profiles depending on the characteristics of the disease, allowing early diagnosis of SSc at the onset of vascular lesions, by comparing the profiles of SSc beginners (<3 years) to established forms (> 3 years). Secondary purposes: - Prognosis: to study the metabolomics profile of SSc when a visceral complication occurs - Diagnosis: to compare the metabolomics profile of SSc to undifferentiated connective tissue disease (UCDT), Raynaud's disease (RD), vascular disease (VD) and healthy controls - Exploratory: to compare the metabolomics profile of blood, urine and skin of SSc patients
