Filter by:The purpose of this study is to learn about the effect of Apollo (a vibrating wearable about the side of an Apple Watch) on fatigue, Raynaud symptoms, depression, quality of life, and disease symptoms in patients with systemic sclerosis. SSc patients frequently have fatigue as a characteristic feature of their disease and fatigue negatively impacts quality of life (Haythornthwaite 2003, Richards 2003, Suarez-Almazor 2007, Basta 2017). The prevalence of fatigue among SSc patients is 75%, with 61% ranking fatigue among their top three most distressing complaints. Fatigue is also associated with poor sleep quality, greater pain and depressive symptoms (Sandusky 2009). We hypothesize that treatment with Apollo over 1 month will improve fatigue. If successful, the Apollo technology will be the first treatment option for fatigue and Raynaud's in this population.
Raynaud's phenomenon (RP) is very frequent in general population (up to 10%). Nailfold capillaroscopy (NFC) is recommended for patients presenting RP, to eliminate systemic disease such as systemic sclerosis. NFC is not easily available in clinical practice. Dermoscopy, used for pigmentary skin lesion screening, may help to detect giant loops, hemorrhages or other capillaries anomalies. However, no study has evaluated the performance of dermoscopy in primary RP. The objective is to determinate which items in dermoscopy are correlated with a normal NFC and predict with a good negative predictive value, a normal NFC in RP patients. The secondary objective is to assess inter-observer reproducibility of dermoscopy in patients with RP.
This is a randomised, double-blind, placebo-controlled, cross-over phase 2 trial investigating the effect of C21 on cold-induced vasoconstriction in subjects with Raynaud's phenomenon secondary to systemic sclerosis. The purpose of the trial is to achieve a vasodilatory effect in subjects with Raynaud's phenomenon by stimulation of the AT2R (angiotensin II type 2 receptor) with C21.
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.
Individuals with Raynaud's phenomenon often experience episodes of reduced blood flow to their fingers and toes during times of stress or cold exposure, causing significant discomfort and pain. Typically, treatment for these individuals involves using drugs like Glyceryl Trinitrate (GTN), which increases blood flow to the fingers and toes by increasing a substance called nitric oxide in the blood. Unfortunately, repeated use of these drugs increases tolerance to them, meaning higher doses are required to produce the same effect. However, increasing the dose can cause more side effects like headaches, and is therefore not considered an ideal long-term therapy. Leafy green vegetables, especially beetroot, contain high amounts of nitrate and are beneficial to blood vessel health, since nitrate from the diet can also be turned into the important blood vessel relaxer, nitric oxide. Unlike GTN, people don't appear to develop a tolerance to dietary nitrate or experience negative side effects. Therefore, this study aims to see if short and longer term beetroot juice supplementation can improve blood flow to the hands and feet in individuals with Raynaud's phenomenon, as well as reduce their pain. This study will tell us how many people are needed for a definitive trial investigating whether beetroot juice can help treat Raynaud's phenomenon. Raynaud's phenomenon can cause significant discomfort and pain to individuals. Dietary nitrate appears to offer a simple, low cost means of improving blood flow to the hands and feet which should reduce both the discomfort and pain experienced characterising this condition. This study will advance our understanding of the causes of Raynaud's phenomenon, specifically the role that the nitrate-nitrite-nitric oxide pathway might play in changing Raynaud's phenomenon symptoms and identifying targets for intervention.
Patients with Raynaud's disease have an increased tendency of chest pain and migraine, and studies indicate that the disease might be associated with increased cardiovascular morbidity and mortality. Furthermore, a certain hyperactivity of the sympathetic nervous system has been demonstrated in these patients. Hyperactivity of the sympathetic nervous system is known to cause decreasing heart function, regardless of the underlying disease. The cardiac autonomic nervous function and thermographic parameters will be assessed in patients with primary and secondary Raynaud's phenomenon and glaucoma as well as in patients diagnosed with autonomic dysfunction such as diabetics and patients with Parkinson's disease in order to compare the function of the cardiac autonomic nervous system and the peripheral response to cold exposure. Potentially, this will lead to a better understanding of the cardiac autonomic nervous function in Raynaud's phenomenon. Moreover, it might give rise to a new perception of the condition and its association to cardiovascular disease. At the Department of Clinical Physiology, the current method of detecting Raynaud's phenomenon is time-consuming and unpleasant to the patient due to cooling for several minutes. Another aim of the PhD study is to implement infrared thermography as a gentler and possibly more sensitive method to replace the currently applied method. The project will also include an epidemiological study based on data obtained from the National Patient Registry, among others. Raynaud's phenomenon will be paired with diagnostic codes of conditions such as diabetes mellitus, Parkinson's disease, glaucoma, and cardiovascular disease.
The prevalence of Raynaud phenomenon (RP), a reversible vaso-constriction with skin discoloration, is 5-10% in general population. Often conventional measures such as warming up or minimizing exposure to cold are not enough and many patients require treatment with a vasodilator therapy. A recent study showed a good efficacy and safety profile of sildenafil, a selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) in RP. Here, the investigators aim to examine the efficacy and safety of Udenafil, a newer PDE5 inhibitor, as compared to amlodipine, a well known calcium channel blocker, in the treatment of secondary RP in Korean patients.
