SLE
What is SLE?
Systemic Lupus Erythrmatosus (SLE) is an autoimmune disorder in which the body’s immune system begins to attack it’s own tissues and cells. Lupus can affect many different body systems such as the kidneys, the joints, skin, heart, lungs, blood vessels, and brain.
Causes of Systemic Lupus Erythrmattosus
The actual cause of the disease is unknown. It is thought that there is not one single cause, but that it is a combination of several factors. The include genetics, environment, and possibly hormonal factors. The cause may be different from one person to another. Genetics is thought to be a factor because of the fact that it runs in families. Environmental factors being looked at as possible causes are sunlight, stress, certain medications, and infectious causes such as viruses.
Symptoms of SLE
Symptoms of the disease vary widely from person to person. They can be mild or severe, and can come and go over time. The most common symptoms include extreme fatigue, painful or swollen joints, unexplained fever, and skin rashes.
Some other less common symptoms include chest pain with deep breathing, hair loss, sensitivity to the sun, anemia, pale or purple fingers and toes from cold and stress, headaches, dizziness, depression and seizures.
Diagnosis of SLE
The diagnosis of SLE can be difficult. Because the symptoms are vague, and commonly indicate other problems, it may take several months or even years for the diagnosis to be made accurately.
The most useful laboratory studies identify certain blood autoantibodies frequently seen in patients with SLE.
