What is lupus?
Lupus is an autoimmune disease in which the immune system attacks healthy tissue. It affects joints, skin, brain, lungs, kidneys and blood vessels, leading to inflammation and tissue damage of the affected organs.

The four types of lupus are:
- Lupus dermatitis: Lupus affecting the skin in the form of a rash.
- Systemic lupus erythematosus (SLE): This type of lupus affects the internal organs and is the most serious type.
- Drug-induced lupus: This type of lupus occurs as a result of an overreaction to certain medications such as Apresoline (hydralazine) or quinidine and Pronestyl (procainamide). It is similar to SLE.
- Neonatal lupus: Lupus affecting an infant as a result of passively acquiring antibodies from a mother with SLE.
