All criteria items now have individual weights (from 2 to 10) and are structured in domains, within which only the highest item is counted. There is one common attribution rule, counting criteria only if there is no more likely alternative explanation. Ten points are sufficient for classification. The new criteria have reached a sensitivity of 96.1% and a specificity of 93.4%. Continue reading “EULAR/ACR New Classification Criteria for Systemic Lupus Erythematosus (SLE)”
No universally recognized classification criteria currently exist for discoid lupus erythematosus (DLE), which has led to problematic heterogeneity in observational and interventional clinical studies across the field. Continue reading “Classification Criteria for Discoid Lupus Erythematosus (DLE)”
Disease activity is assessed using a combination of the clinical history, physical examination, organ specific functional tests, and serologic studies.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown cause that can affect virtually any organ of the body. Immunologic abnormalities, especially the production of a number of antinuclear antibodies (ANA), are a prominent feature of the disease.
