Systemic Lupus Erythematosus Complicated with Listeria Monocytogenes Infection in a Pregnant Woman.

A 41-year-old woman with systemic lupus erythematosus (SLE) was admitted to our hospital due to a fever at 35 weeks of pregnancy. Laboratory testing revealed a low platelet count and elevated liver enzymes. Emergency Caesarean section was performed due to the risk of SLE exacerbation or hemolytic anemia, elevated liver enzyme, and low platelet count syndrome. Based on the blood culture results, the patient was diagnosed with Listeria monocytogenes bacteremia. She was treated with ampicillin and eventually recovered, and the neonate did not have any complications. Pregnant women with SLE are at risk of complications. Listeriosis should be monitored for and, if found, managed appropriately.
