It is estimated that 1.5 million Americans, and 119,000 Texans have a
form of lupus. Lupus is a chronic and potentially life-threatening
autoimmune disease that can be devastating for people with lupus. No
cure or satisfactory treatment exists...For the first time in 52 years, a
specific drug for lupus was approved by the FDA in March 2011. There is
hope, and with your help we can find a cure for lupus.
