Official title
Arginine Flux and Nitric Oxide Production in Patients With MELAS Syndrome and the Effect of Arginine and Citrulline Supplementation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Introduction Baylor College of Medicine and Texas Children's Hospital are recruiting individuals with MELAS syndrome for a clinical study. MELAS syndrome is a mitochondrial disease; patients with this disease have muscle weakness and often develop brain strokes, where blood does not flow normally to different parts of the brain. It is believed that these strokes could be due to decreased production of nitric oxide, a naturally occurring compound important for normal blood vessel function. Nitric oxide is made from arginine and citrulline that are normally found in our bodies. What is the purpose of this study? The purpose of this study is to measure nitric oxide in individuals with MELAS and see if giving arginine or citrulline will increase the formation of nitric oxide. Nitric oxide is thought to be helpful in preventing strokes. Therefore, if arginine and/or citrulline are shown to increase the formation of nitric oxide, they could be used to prevent or treat the strokes in patients with MELAS syndrome.
