Neonatal lupus erythematosus (NLE) is a rare disease characterized by typical clinical features and the transplacental passage of maternal autoantibodies, particularly anti-SSA/Ro. The major clinical manifestations are cutaneous lupus lesions, congenital heart block, hematological disorders, and hepatobiliary diseases. We report a case of NLE presenting with multiple round and oval target-like erythematous skin lesions and abnormal liver function, born to a clinically asymptomatic mother whose diagnosis was made retrospectively only after her newborn's diagnosis. Both the infant and the mother were positive for the anti-SSA/Ro and anti-SSB/La antibodies.

Neonatal lupus(NL) is characterized by typical clinical features and the presence of maternal autoantibodies. The principal serologic markers of NL are anti-Ro/SSA or anti-La/SSB maternal autoantibodies, which are transferred across the placenta and can be detected for the first few months of the affected child. The major clinical manifestations are cardiac disease, notably congenital heart block, and cutaneous lupus lesions. Hepatobiliary disease is relatively rare clinical manifestation of NL. We experienced a case of NL with abnormal liver function test and skin lesion.

Macrophage activation syndrome (MAS) is a potentially life-threatening complication in many autoimmune diseases. Early recognition and intervention are essential for a favorable outcome. Neonatal lupus, an acquired autoimmune disease in neonates caused by the transplacental passage of maternal autoantibodies, is rare and usually self-limited. Herein, we report a case of MAS in a patient with neonatal lupus, which improved with intravenous immunoglobulin.

Neonatal lupus erythematosus(NLE) is a distinct subset of lupus characterized by cutaneous findings, cardiac conduction defects, hepatic or hematologic abnormalities. These manifestations are associated with the presence of maternal auto-antibodies such as anti-SSA/Ro, anti-SSB/La, and rarely anti-RNP($U_1RNP$) antibodies. Cases of $U_1RNP$ antibody-positive NLE have somewhat atypical cutaneous manifestation without cardiac or systemic abnormalities. We report a case of cutaneous NLE associated with $U_1RNP$ antibodies.

Thrombocytopenic patients without detectable bound antiplatelet antibody should be diagnosed with idiopathic thrombocytopenic purpura (ITP) if no other cause of their decreased platelet count could be found. More recently the term "autoimmune thrombocytopenic purpura (ATP) has supplanted ITP since the disease is related to the production of autoantibodies against one's own platelets. This entity should not be confused with isoimmune thrombocytopenic purpura (also called alloimmune thrombocytopenic purpura). In this cases maternal antiplatelet antibodies directed against the PLA 1 antigen on the fetal platelets causes severe fetal and neonatal thrombocytopenia in a situation analogous to Rheusus disease. Antibodies to the negatively charged phospholipids, lupus anticoagulant, and anticardiolipin have been linked to adverse pregnancy events. Pregnant women possessing these antibodies have an increased risk of spontaneous abortion, stillbirths, intrauterine fetal growth retardation, preterm birth, and arterial and venous thrombosis. Antiphospholipid antibodies decrease or may even disappear between pregnancies only to recur with increased activity in a subsequent pregnancy and lead to loss. We have experienced a case of antiphospholipid syndrome associated with autoimmune thrombocytopenic purpura in patient with recurrent spontaneous abortion. So we report this case with a brief review of literatures.
