Up to 322,000 persons have definite or probable systemic lupus erythematosus (SLE). Persons of all ages are affected, including children. At greatest risk are women of childbearing age, 15 to 44 years; men are at lower risk. Minority and ethnic groups are affected more than whites.
SLE diagnosis may be challenging because the signs and symptoms are not specific. The diagnosis may be made too easily when only a positive blood test is used.
Several recent studies have reported on new aspects of lupus diagnosis, management, and comorbidities. Read on for brief summaries of the latest research findings.
