Filter by:In this double-blinded, placebo-controlled, fixed-dose, study patients will be randomly assigned to take placebo or 20 mg tadalafil thrice weekly for 6 weeks. After 6 weeks a wash out period of 2 week will be observed and then the two groups will be switched over to receive the other drug. We planned a priori to include 20 patients. The concomitant medication for treatment of rheumatic disease remained unchanged during the whole study. Patient will undergo clinical and lab evaluation for organ damage for kidney and lungs. ECHO heart will be done at base line to assess the PAH and LV function and repeated at the end of the study. Blood pressure will be recorded at each visit. A physician unaware of the treatment group will record skin score and appearance of new cutaneous ulcers. The primary outcome variables will be frequency and duration of Raynauds attacks, evolution of trophic digital lesions and change in flow mediated dilatation of the brachial artery. Flow mediated dilatation of the brachial artery will be done at baseline 6 and 12 weeks.
This is a pilot study analyzing the effect of sildenafil therapy on digital ulcers in systemic sclerosis. We want to analyze ulcer healing by measuring the size of digital ulcers and their count and analyze the effect of sildenafil on angiography.
The purpose of the study is to examine the safety and effectiveness of a reduced intensity conditioning regimen and allogeneic bone marrow transplant for people with systemic sclerosis. In an allogeneic bone marrow transplant procedure, bone marrow is taken from a healthy donor and transplanted into the patient. Bone marrow can be donated by a family member or an unrelated donor who is a complete tissue type match. Participants will receive the chemotherapy and low dose radiation conditioning regimen consisting of the following: Fludarabine will be given intravenously for 5 days. Cyclophosphamide will be given intravenously on the first and second day. After completing the fludarabine and cyclophosphamide, patients will receive a single low dose of total body irradiation. The next day, patients will receive the allogeneic bone marrow transplant. On the third and fourth day after the transplant, patients will receive high dose intravenous cyclophosphamide. This is given to help prevent two complications: (1) graft rejection, which occurs when the body's immune system rejects the donor bone marrow, and (2) graft-versus-host disease (GVHD), which is when the donor immune cells attack the patient's normal tissues. On the fifth day after the transplant, patients will start receiving two additional medications: tacrolimus and mycophenolic acid (MPA, Myfortic), to help prevent GVHD. Patients will receive mycophenolic acid for about 5 weeks and tacrolimus for about 6 months. Also beginning on the fifth day after the transplant, patients will receive daily injections of a growth factor called granulocyte-colony stimulating factor (G-CSF), which is a protein that increases the white blood cell count; G-CSF will be continued until the patient's white blood cell count has returned to normal levels. Patients will remain closely monitored either in the outpatient clinic setting or in the hospital for approximately 2-3 months after the transplant, but possibly longer if there are complications. Follow-up study visits will occur at 6 months and then at 1, 2, 3, 4, and 5 years after the transplant. Study researchers will keep track of the patient's medical condition after leaving the transplant center by phone calls or mailings to patients and their doctors once a year for the rest of the study participants' lives.
This study compared the efficacy of different dosages of long-term iloprost treatment on Raynaud's phenomenon, ulcer healing, skin thickening, and progression of internal organ sclerosis in systemic sclerosis (SSc). Methods. 50 SSc patients were 1:1 randomised either for maximally tolerated dose up to 2 ng/kg body weight [bw] per minute or low dose (0.5 ng/kg bw per minute) intravenous iloprost administration, for six hours daily over 21 days. The effect on RP, ulcer healing, skin thickness, oesophagus function, lung involvement as assessed by lung function parameters FVC and DLCO, and side effects were measured. Conclusions. The efficacy of prolonged administration of iloprost is also achieved with low dose iloprost by long term treatment. The effects suggest a disease-modifying capability of iloprost, but further studies are needed to proof this hypothesis.
The purpose of this study is to evaluate the role of stress echocardiography, compared to standard echocardiography in the early identification of pulmonary arterial hypertension in systemic sclerosis. To evaluate the role of BNP in this setting.To analyze data recorded with respect to the parameters commonly used for SSc evaluation (eg thorax HRCT, pulmonary function tests + DLCO, nailfold capillaroscopy, etc); these parameters are available starting for 1999.
This study investigates the efficacy and safety of STI571 for the treatment of fibrosis in participants with systemic sclerosis. Other purposes of the study were to investigate whether STI571 is effective in improving lung functions and other test results called biomarkers. Whether STI571 is well-absorbed in systemic sclerosis participants' gut was also investigated by testing the drug level in the blood (pharmacokinetics).
This study will evaluate the safety, tolerability, and mechanism of action of multiple doses of QAX576 in patients with pulmonary fibrosis secondary to systemic sclerosis
The purpose of this research study is to test the safety, tolerability, and effectiveness of Topical AmphiMatrix with Nitroglycerin (MQX0503) to relieve Raynaud's symptoms and increase blood flow to the fingers.
Transforming growth factor-beta 1 (TGF-β1) is consistently over expressed in most fibrotic diseases and displays a variety of profibrotic effects in fibroblasts. Activation of TGF-β receptors induces the activation of several kinase signalling cascades leading to the phosphorylation of SMAD proteins as well as to the activation of SMAD-independent kinases that collectively activate ECM synthesis and fibroblast growth and differentiation into myofibroblasts. TGF-β1 is one of the main mediators in the fibrotic process, associated to both scarring and a long list of pathologies related to chronic inflammation and which affect all type of organs and tissues. An increase in TGF-β1 mRNA and protein levels has been described in these processes. Peptide 144 (P144) is the acetic salt of a 14mer peptide from human TGF-β1 type III receptor (betaglycan). P144 TGF-β1-inhibitor has been specifically designed to block the interaction between TGF-β1 and TGF-β1 type III receptor, thus blocking its biological effects. P144 has shown significant antifibrotic activity in mice receiving repeated subcutaneous injections of bleomycin, a widely accepted animal model of human scleroderma, and could contribute to the development. The purpose of this study is to asses the efficacy and safety of topical application of P144 in the treatment of skin fibrosis in patients with systemic sclerosis.
The purpose of this study is to verify effect and tolerability of imatinib on pulmonary and skin fibrosis in patients affected by systemic sclerosis.
