Abstract
Neonatal lupus (NL) is an autoimmune disease acquired in utero after exposure to antibodies produced by the maternal immune system against Ro and La antigens. It is considered as a syndrome since it can comprise manifestations including cardiac, cutaneous, and hematologic abnormalities. In many cases, mothers are clinically asymptomatic and only identified with serologic abnormalities when gestational surveillance reveals foetal bradycardia.
A term baby girl was born by c-section due to prolonged bradycardia, with one-minute APGAR score was five and five-minute APGAR was seven. She was the second baby from gemelli pregnancy of P4A0 mother. On further observation, the respiratory distress deteriorated, with the heart rate around 80-100 beats/minute on electrocardiogram showed total AV block. Laboratory examination showed anaemia, thrombocytopenia, hypoalbuminemia, and elevated C-reactive protein. The chest x-ray revealed pleural effusion, and from echocardiography, there was a small patent ductus arteriosus. ANA panel test showed positive 3+ for anti-Ro (SS-A) and Ro-32 recombinant. During treatment in NICU, this patient received dopamine, dobutamine, invasive mechanical ventilation, and chest tube thoracostomy installation. Later, she was referred to tertiary health care for pacemaker treatment.
NL is an uncommon autoimmune disease that is present at birth. Affected infant develop various symptoms and complications, the most significant potential such as congenital heart block. Congenital heart block may manifest in various degrees. In this case, NL presented with a complete heart block which required a pacemaker for treatment.
