It is possible that the main title of the report Neonatal Lupus is not the name you expected.
Neonatal lupus is a rare acquired autoimmune disorder that is present at birth (congenital). Affected infants often develop a characteristic red rash or skin eruption. The most significant potential complication is a heart condition known as congenital heart block. Congenital heart block does not resolve within the first several months of life and infants may ultimately require a pacemaker. Some infants develop only skin symptoms, some infants develop only heart symptoms, and, less often, some infants develop both. Less common findings include liver disease, an abnormally large head circumference (macrocephaly), and/or low numbers of circulating blood platelets that assist in blood clotting functions (thrombocytopenia), white blood cells that help fight infection (neutropenia), and red blood cells that help deliver oxygen to the body (anemia). Neonatal lupus results from specific autoantibodies that travel from a pregnant woman to her developing fetus. These autoantibodies damage specific fetal tissue through a process that is not fully understood.
Neonatal lupus is not the infant form of lupus (systemic lupus erythematosus); the name was given to this disorder because the skin rash resembles the one associated with lupus. The affected infant or child does not have systemic lupus erythematosus and often the mother does not either. Neonatal lupus is a distinct, separate disorder.
