Systemic lupus erythematosus
The rate of SLE varies between countries, ethnicity, and sex, and changes over time. In the United States, one estimate of the rate of SLE is 53 per 100,000; other estimates range from 322,000 to over 1 million. In Northern Europe the rate is about 40 per 100,000 people. SLE occurs more frequently and with greater severity among those of non-European descent. That rate has been found to be as high as 159 per 100,000 among those of Afro-Caribbean descent. Childhood-onset systemic lupus erythematosus generally presents between the ages of 3 and 15 and is four times more common in girls.
Alliance for Lupus Research
The Alliance for Lupus Research (ALR) is an American voluntary health organization based in New York City whose mission is to find better treatments and ultimately prevent and cure systemic lupus erythematosus (SLE or lupus), a debilitating autoimmune disease, through supporting medical research. It was co-founded by philanthropist Woody Johnson, who is also the organization's chairman. As of 2013 the ALR's cumulative research commitment was $81,000,000.
