Clinical Features, Autoantibodies, and Outcome of Neonatal Lupus Erythematosus.

To explore the clinical features, autoantibodies, and outcome of neonatal lupus erythematosus (NLE). We retrospectively reviewed all NLE cases from January 2012 to May 2019 that occurred in our department. Cutaneous, cardiac, hematologic, and hepatobiliary manifestations were found in 36.7%, 56.7%, 56.7%, and 30.0% of cases, respectively. The presence of anti-SSA antibodies was correlated with cardiac presentation ( = .026) and the presence of anti-SSB antibodies was associated with cutaneous lesions ( = .015). During the follow-up, one patient with a third-degree atrioventricular block died, and a third-degree AV block persists in a child without a pacemaker at 4-years of age. No other manifestations of NLE were observed after the age of 12 months. Anti-SSA and anti-SSB are associated with cardiac and cutaneous manifestations in NLE. Most children with NLE have excellent outcomes with symptom resolution by one year. Complete congenital heart block may persist.
