Issues and advances in the management and pathogenesis of cutaneous lupus erythematosus.
Evidence-based therapy for cutaneous lupus is lacking. A new clinical assessment tool for cutaneous lupus, the CLASI score, will enable more standardized assessments of response to therapy. Anti-Ro autoantibodies are associated with photosensitive SLE and SCLE, and they play a role in cell survival following ultraviolet exposure. Ro also functions in quality control of small RNAs, important in the prevention of autoimmune disease. Drug-induced lupus erythematosus can be anti-Ro- or anti-dsDNA-associated; SCLE and photosensitivity are characteristic of Ro-positive drug-induced lupus. Biologic therapies and IVIg are being studied for the treatment of SLE and cutaneous lupus. Large, controlled trials are needed, not only to evaluate newer therapies, but also to substantiate and define the usage of traditional therapies for cutaneous lupus erythematosus.
