Triplets with systemic lupus erythematosus

We present herein the first case report of identical triplets who developed systemic lupus erythematosus (SLE). The children were diagnosed as having SLE in reverse birth order at ages 8, 9, and 11 years. Although genetically identical, each sibling manifested different clinical signs and symptoms; however, all 3 children did manifest skin rash, fatigue, and biopsy‐proven glomerulonephritis at different ages. Findings of laboratory studies were similar, including positivity for antinuclear antibodies, anti–native DNA, and anti–double‐stranded DNA, as well as low levels of complement. These findings confirmed SLE in each sibling.
