Active clinical trials for "Raynaud Disease"

Raynaud's Phenomenon (RP) is the most common vasospastic disorder encountered by hand surgeons with an estimated prevalence of 5% in the general population. It's manifestations are broad, and can range from minor to severe. Sometimes it can be refractory to treatments. The goal of this study is to evaluate the efficacy of Botulinum toxin (BT) in the treatment of treatment refractory RP by objective and subjective measures.

In this feasibility study, we aim to explore therapeutic Rheopheresis (RheoP) as a novel treatment option for SSc-associated Raynaud's phenomenon and/or digital ulcers and compare it to the standard of care treatment (intravenous iloprost. RheoP has been used for RP/DU with some success in observational studies, nevertheless, the optimal treatment modality, duration, or frequency of RheoP (and PEX in general) in SSc has not been established as of yet.

The main objective is to assess the feasibility of treatment by injecting botulinum toxin A into the hand or foot of patients with signs of critical ischemia secondary to Buerger's disease. The injection of botulinum toxin A is carried out at the end of a single session during an hospitalization. Furthermore, tolerance and effects on the disease are evaluated at 1, 3 and 6 months post injections.

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.

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

The purpose of this study is to investigate whether the use of the study drug (Exparel) is safe and effective for treating circulation problems and pain in the hand or fingers.

The purpose of this study is to determine whether oral temanogrel improves digital blood flow in participants with Raynaud's phenomenon secondary to systemic sclerosis (SSc-RP) as a potential safe and effective treatment for symptoms associated with SSc-RP.

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 study aims to investigate the effect of abobotulinum toxin A on the symptoms of Raynaud's phenomenon.
