Active clinical trials for "Scleroderma, Systemic"

This is a mechanistic research study to evaluate the relationship between cough, reflux, and aspiration in patients with systemic sclerosis (scleroderma).

The aim of the study is to compare the exposure to environmental and professional toxics by patients with systemic scleroderma and by patients not achieved by this pathology.

The Scleroderma bioreposiTOry and Pathogenesis Study (STOP Scleroderma) will help researchers use clinical data and human biospecimens to investigate why scleroderma patients develop certain complications from their disease. Patients with confirmed scleroderma, raynauds or positive autoantibodies are invited to participate. This research may help us understand how to prevent and treat scleroderma and other diseases.

The goal of this study is to develop a new way to assess skin thickness in patients with scleroderma (systemic sclerosis). The study will test how well a new imaging method called optical coherence elastography (OCE) compares to the current clinical method used to estimate skin thickness, the modified Rodnan Skin Score (mRSS).

Systemic sclerosis (SSc) is a systemic disease that involves various organs such as the skin, kidneys, gastrointestinal tract and lungs. Dysfunction of the thyroid gland is prevalent in these patients and may be related to thyroid fibrosis or to thyroid autoimmune disease, i.e. hashimoto's thyroiditis. Thyroid nodules are prevalent in the general population, although some reports suggest they might be more frequent in patients with SSc. Hashimoto's thyroiditis, by itself, carries a higher risk for thyroid nodules and thyroid cancer. The aim of the study:To characterize sonographycally the thyroid gland of patients with SSc with and without Hashimoto's disease

The purpose of this trial is to study the proportion of scleroderma patients who suffer from asymptomatic coronary atherosclerosis compared to healthy controls.

Scleroderma is likely caused by a combination of factors, including an external trigger (infection or other exposure) and a genetic predisposition. The Scleroderma Registry will conduct genetic analyses for disease-related genes in patients with scleroderma and their family members (parents, brothers, and sisters).

Drug of investigation: Mycophenolate mofetil (MMF), given orally as a tablet twice daily. Dosage of drug: This study recruits patients who have been prescribed a steady dose of MMF in the range between 1000 and 3000 mg daily by their physician. Design: This is an open-label PK study. Disease studied: Systemic sclerosis (SSC, scleroderma). Variables assessed: Estimated AUC0-12 for MMF. Gastrointestinal manifestations of SSc. Concomitant medication. Study population: Inclusion criteria: Diagnosis of SSC fulfilling the 2013 classification criteria for this disease. Participant should have been prescribed a stable dose of MMF tablets, taken twice daily, for at least 3 months prior to the study. Exclusion criteria: Failure to comply with study protocol. Limited access to repeated venous puncture. Recipient of organ transplant. Pulmonary arterial hypertension. Number of participants: The study aims at the inclusion of 35 subjects. Primary objective: To investigate the PK of orally ingested MMF in SSC. Secondary objectives: To investigate how SSC manifested in the gastrointestinal (GI) tract may alter the PK of MMF. To investigate how the PK of MMF in SSc is altered by medications often used in SSC, i.e. proton pump inhibitors (PPI), NSAID and calcium channel blockers.

Systemic Sclerosis (SSc) is an inflammatory chronic disease that can lead to structural damage and handicap. The SSc physiopathology is multifactorial, including genetic and environmental risk factors. The identification of environmental factors implication is crucial to understand the SSc mechanism, and improves the diagnosis and the treatment of the disease.

Systemic sclerosis (SSc) is a generalized disorder of connective tissue, arterioles and microvessels, characterized by the occurrence of fibrosis and vascular obliteration phenomena. The alterations in lung microvessels are found in pulmonary involvement of scleroderma, which are the most serious complications of the disease. In pulmonary emphysema, there are also changes in pulmonary microvasculature, which are involved in the onset and development of the disease. The confocal endomicroscopy is an endoscopic technique which can be performed during a bronchoscopy. This technique makes it possible to observe in real time the most distal pulmonary elements at the microscopic scale. After injection of fluorescein, then the technique of observing the pulmonary microvasculature, in vivo and in situ. The characterization of microvascular lesions in these two pathologies could improve understanding of their mechanisms and ultimately improve the early management of patients.
