Neonatal lupus erythematosus: report of a case.

Abstract

We present the first report of neonatal lupus erythematosus from Taiwan. A female baby, born to a mother with documented systemic lupus erythematosus (SLE), developed cutaneous lupus lesions after phototherapy for hyperbilirubinemia. She had additional clinical features of hemolytic anemia and thrombocytopenia. Detailed serological and immunogenetic studies were performed. Transplacental passage of both anti-SSA/Ro and anti-SSB/La antibodies were demonstrated and their disappearance at the age of 6 months correlated with regression of clinical symptoms. This patient inherited human leukocyte antigen (HLA) A11, Bw60 Cw3, DR2 and Aw33, Bw57, Cw7, DRw6 from her father and mother, respectively. A long-term follow-up is required for observing whether she will develop SLE in the future.
