SLE. A chronic inflammatory connective tissue disease marked by skin rashes, joint pain and swelling, inflammation of the kidneys, inflammation of the fibrous tissue surrounding the heart (i.e., the pericardium), as well as other problems. Not all affected individuals display all of these problems. Also called lupus.

Autoimmune diseases arise from an overactive immune response of the body against substances and tissues normally present in the body. Today there are more than 40 human diseases classified as either definite or probable autoimmune diseases and they affect 5-7% of the population. Almost all autoimmune diseases appear without warning or apparent cause and most patients suffer from fatigue.
