Lupus erythematosus:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of SLE remains a mystery, but evidence points to interrelated immunologic, environmental, hormonal, and genetic factors. Autoimmunity is thought to be the prime causative mechanism. In autoimmunity, the body produces antibodies against its own cells such as the antinuclear antibody. The formed antigen-antibody complexes can suppress the body’s normal immunity and damage tissues. Patients with SLE produce antibodies against many different tissue components, such as red blood cells (RBCs), neutrophils, platelets, lymphocytes, or almost any organ or tissue in the body.
Certain predisposing factors may make a person susceptible to SLE. Physical or mental stress, streptococcal or viral infections, exposure to sunlight or ultraviolet light, immunization, pregnancy, and abnormal estrogen metabolism may all affect this disease’s development.
SLE may also be triggered or aggravated by treatment with certain drugs — for example, procainamide, hydralazine, anticonvulsants and, less commonly, penicillins, sulfa drugs, and hormonal contraceptives.
SLE strikes 8 times more females than men, increasing to 15 times more during childbearing years. It occurs worldwide but is most prevalent among Asians and Blacks.

About prevalence and incidence statistics:
The term 'prevalence' of Lupus usually refers to the estimated population
of people who are managing Lupus at any given time.
The term 'incidence' of Lupus refers to the annual diagnosis rate,
or the number of new cases of Lupus diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
