Filter by:This is a Phase 3, multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of iloprost on the frequency of and relief from symptomatic digital ischemic episodes in subjects with systemic sclerosis.
Background: Raynaud's phenomenon is a vasospasm of the extremities, leading to extensive discomfort in daily life and potentially severe ischemia. Some patients are resistant to conventional vasodilatory drug treatment. In the University Medical Center Groningen, single-port thoracoscopic sympathicotomy (SPTS) was developed. This is a new minimally invasive endoscopic technique, extensively limiting surgical burden. In many hospitals in the Netherlands, this operation is sometimes performed on patients with Raynaud's phenomenon. However, the techniques used are more invasive than the SPTS technique. Furthermore, studies on sympathectomy and sympathicotomy in Raynaud's are limited and encompass obsolete more invasive techniques. Also, it is unclear which patients would benefit the most and for how long and in which percentage of patients treatment effects persist over time. In a recent study on the new SPTS technique, it was found that one month after the procedure, the Raynaud's attacks were substantially reduced and the hand perfusion increased on the operated side. Based on these short term effects and previously reported broad experience with this technique for other indications, it is possible to offer this option to a broader range of patients with Raynaud's as a reasonable and safe treatment option. However, whether the effects persist on the long-term needs to be established. Main research question: The aim of the study is to assess the 5 year efficacy and outcome in patients with primary and secondary Raynaud's phenomenon in whom SPTS has been performed. Design (including population, confounders/outcomes): Patients with Raynaud's, who will undergo SPTS in patient care setting, will be included. Data from the patient file will be collected, including vascular measurements to assess hand perfusion, a Raynaud diary (Raynaud condition score, duration and frequency of the attacks), quality of life questionnaires, and adverse events.

Background CREST is an acronym for the cardinal clinical features of the syndrome (Calcinosis, Raynaud phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia) and part of the heterogeneous group of sclerodermas. Calcinosis is the pathologic calcification of soft tissues. When symptomatic, they can be tender and painful, ulcerate, and drain a white chalky substance. With time, heterotopic bone formation may occur. Inflammatory reactions also intermittently occur at the site of calcinosis. It has been suggested that TGF-beta3 plays a major role in the pathogenesis of calcinosis. A variety of medical therapies have been used to try to alleviate patient symptoms. These include pharmacological approaches (e..g., warfarin), surgical curettage or excision, as well as carbon dioxide laser treatments. No consistently reliable pharmacological treatment seems to be available to prevent or eliminate calcinosis. Curettage and excision and carbon dioxide laser of localized painful large deposits can relieve symptoms but recurrence is common. In addition, aggressive curettage or excision can damage deeper neurovascular structures. While calcinosis is associated with significant morbidity its treatment remains a challenge. Photobiomodulation (PBM) has been shown to promote wound healing, suppress inflammatory reactions and regulate collagen synthesis in a number of in vitro and in vivo studies. Human skin contains photolabile nitric oxide (NO) derivatives which decompose after UVA irradiation and release vasoactive NO. However, aside from blue light, barely nothing has been reported about the effects of red and NIR wavelengths. Method A custom-built air tight sleeve which envelopes the forearm of a subject will be used to measure the NO emanating from the skin under photobiomodulation conditions (red & NIR) and quantified by chemiluminescence detection. Simultaneously, CREST patient's hands exhibiting calcinosis and/or Raynaud phenomenon will be exposed to exogenous gaseous nitric oxide (INOMAX) to determine the vascular impact of this approach. This case series will assess Light Emitting Diode (LED) based PBM therapy as a treatment alternative for cutaneous calcinosis and the effects of gaseous NO on calcinosis and/or Raynaud phenomenon in CREST patients.
Raynaud's phenomenon (RP) is a common vascular disorder that affects approximately 10% of the general population. RP is associated with significant morbidity that may include loss of the digits due to repeated episodes of vasospasm of the digital arteries in addition to significant impairment of quality of life. It is well known that cold exposure precipitates episodes of RP, but the mechanism for cold sensitivity is not known, and treatment of RP is not satisfactory to the patients and their physicians. The goal in this study is to test the possibility that non invasive vagus nerve stimulation (nVNS) with gammaCore which is already approved by the FDA for headaches and migraines may be an effective and well tolerated therapy for Raynaud's Phenomenon.
This is a Phase 2, multicenter, double-blind, randomized, placebo-controlled study to evaluate the effect of iloprost on the symptomatic relief of Raynaud's Phenomenon attacks in subjects with symptomatic Raynaud's Phenomenon secondary to Systemic Sclerosis.
The study aims to investigate the effect that supplementing the diet with cocoa flavanols has on vasospasm symptoms and temperature regulation in women with primary Raynaud's phenomenon (PRP). Participants will be randomised to consume either high flavanol cocoa extract or low flavanol cocoa (placebo) daily for 3 months.
The investigators aim at comparing the efficacy of a 2 weeks supplementation by L-citrulline or beetroot juice to L-citrulline placebo or denitrated beetroot juice respectively on Raynaud's phenomenon severity. Raynaud's phenomenon severity will be assessed through the Raynaud Condition Score, daily frequency of attacks or cumulative attack duration (expressed as min) daily collected by patients in a diary. Each Volunteer will choose his own main outcome among these 3 criteria.
This study aims to assess whether or not a single injection schedule of botulinum toxin A (BTX-A) in both hands improves Raynaud phenomenon (RP) secondary to systemic sclerosis (SSc) better than a placebo at 4, 12 and 24 weeks after the treatment. This study's hypothesis is that the number of RP attacks per week from baseline to 4 weeks after treatment is significantly lower in the group treated with BTX-A than in the control group treated by the placebo. Furthermore, BTX-A in both hands is expected to improve both symptomatic (attack frequency, digital ulcer healing) and functional (pain, hand function, quality of life) symptoms of RP secondary to SSc more than placebo.
The purpose of this study is to analyze the effects of an intervention with galvanic electrical current on the number of attacks , temperature, pain, peripheral blow flow and upper limb functionality in patients with Raynaud's Phenomenon in comparison to a control group that will maintain their habitual treatment.
