Filter by:The Purpose of this study is to determine the response to two different strengths of a topical gel containing nitroglycerin in patients with Raynaud's disease.
This trial will test the efficacy of St. John's Wort (SJW) as a supplement, in the treatment of Raynaud's phenomenon (RP). The investigators are hypothesizing that taking SJW 300mg, 3 times a day will decrease the frequency, duration, and severity of RP attacks when compared to placebo. Patients with RP will answer questionnaires and self-evaluate their symptoms of RP as a baseline. Then they will be assigned to either a treatment (will receive SJW capsules) or placebo (will receive non-therapeutic capsules) group. They will be required to take their capsules, self-evaluate their progress and be evaluated every two weeks in a clinic. The treatment phase will last six weeks. This trial will be conducted in a way to mimic the normal usage of natural products. Patients will not be required to stop any current treatment for RP.
The purpose of this study is to investigate the efficacy and safety of a topical gel formulation of nitroglycerin, in comparison to a matching placebo, for patients with moderate to severe primary Raynaud's phenomenon or patients with Raynaud's phenomenon secondary to autoimmune diseases, such as scleroderma.
The purpose of this study is to determine, in comparison to a placebo control, the response to two dosage strengths of a topical gel formulation of nitroglycerin, MQX-303, in the determination of finger blood flow and skin temperature in the fingers of patients with moderate to severe Raynaud's phenomenon, follwoing exposure to cold temperatures. Blood flow is determined by scanning laser Doppler equipment and skin temperature is measured using attached thermistor probes. Following baseline measurements, the study gel is applied, the hand is placed in a cold chamber, and then blood flow and skin temperature are monitored for the next two hours. Each patient will receive multiple doses on different days so that each can serve as his/her own control in interpreting the response.
The aim of the study is to investigate the efficacy and safety of EGb 761® in patients with the primary Raynaud phenomenon, with regards to the frequency, duration and severity of vasospastic attacks.
Juvenile secondary Raynaud’s (ray-knows) Phenomenon is a disorder of the blood vessels in the fingers and sometimes can affect the toes, nose, or ears. Children with secondary Raynaud’s Phenomenon have an underlying condition such as systemic lupus, scleroderma, or mixed connective tissue disease. When children with secondary Raynaud’s are exposed to chilly or cold conditions from weather, cold temperatures, or even holding cold items from the refrigerator, their fingers may become cold, numb, hurt, and/or turn purple or white. The investigational drug, Pletal(cilostazol), which has been approved for other conditions, inhibits the ability of one type of blood cell, platelets, to form blood clots, and also widens narrowed blood vessels. It has been used in a variety of other conditions in which blood flow is decreased. This study will test the safety and effectiveness Pletal(cilostazol) to lessen the severity of the symptoms and decrease the number of secondary Raynaud’s episodes in juvenile patients.

When children with primary Raynaud’s Phenomenon are exposed to chilly or cold conditions from weather, cold temperatures, or even holding cold items from the refrigerator, their fingers may become cold, numb, hurt, and/or turn purple or white. Children with primary Raynaud’s Phenomenon have no underlying systemic disease. The cause for their symptoms is unknown.

OBJECTIVES: I. Evaluate the safety and efficacy of oral iloprost, a prostacyclin analog, in patients with Raynaud's phenomenon secondary to systemic sclerosis.
To determine the relative efficacy of usual medical care and a course of treatment by thermal biofeedback in reducing vasospastic attacks characteristic of Raynaud's syndrome. Also, to confirm the frequency and severity of attacks, examine the role of psychophysiological factors in precipitating attacks, and assess the influence of treatment on health quality of life.
