Filter by:Sickle cell disease (SCD) is the most frequent inherited disease in the world. Literature reports that SCD patients display intolerance to exercise, important muscle weakness and profound remodeling of skeletal muscle including amyotrophy and rarefied microvascular network. Because strenuous exercise induces acidosis, hemorheological alterations, endothelial activation and oxidative stress, it constitutes a potential triggering factor of sickling and vaso-occlusive crisis. As a consequence, physical activity is usually discouraged in patients with SCD. However, moderate and regular physical activity seems to be not only safe but also beneficial for SCD patients.
Sickle Cell Anemia is caused by an inherited hemoglobin disorder. Healthy red blood cells are discoid and can deform and move through small blood vessels to carry oxygen to all parts of the body. In sickle cell disease, as red blood cells circulate and oxygen is released in the circulatory system, the deoxygenated abnormal hemoglobin S can begin to polymerize. When this occurs, the red blood cells can become sticky and elongated. These sickled red blood cells are less flexible and will obstruct small blood vessels and block normal red blood cells from traveling through the circulatory system, which limits oxygen delivery to tissues and organs. This is known as a "sickle crisis". Patients suffering from a sickle crisis experience severe pain and are at risk of stroke, heart attack or even death. By lowering the level of oxygen pressure at which sickling occurs and opening the vasculature and rapidly delivering oxygen directly to ischemic tissues, the addition of MP4CO to existing treatment protocols may alleviate pain associated with a sickle cell crisis, abort a crisis and/or potentially reduce the duration of a crisis. This could mean less time in the hospital and an improved quality of life for patients with sickle cell anemia.
