ABOUT THE DISEASE
WHAT IS IT
The Sickle Cell Disease gene causes changes in hemoglobin, a pigment found in red blood cells that is responsible for oxygenating the blood and all the tissues of the body.
This alteration causes the cell to elongate, which loses its original shape, similar to a bean grain, and takes on a more elongated shape, resembling a sickle. Hence, the name Sickle Cell Anemia.
In addition to the change in shape, sickle cell disease makes the cell more rigid, less elastic. This interferes with their circulation in the blood. When transiting through thinner blood vessels (the capillaries), the cells are unable to proceed, which leads to blockage (blockage) of the vessel.
As a result, an area of tissue will be without blood supply, that is, without oxygenation. This area is called infarcted or vaso-occluded.
This phenomenon can occur in all tissues, so Sickle Cell Disease is considered systemic, that is, it can affect various parts of the body.
In each of them it will cause local infarction: in the heart it will result in some heart disease, in the lungs it can cause pneumonitis, the bones can develop necrosis and so on.
