Central nervous system vasculopathy in neonatal lupus erythematosus

Central nervous system involvement in neonatal lupus erythematosus (NLE) has not been previously reported, We report four patients with NLE, all with complete congenital heart block and three with cerebral ultrasound and color Doppler flow imaging (CDFI) studies demonstrating evidence of associated vasculopathy in the gangliothalamic vasculature, CDFI confirmed blood flow through the affected vessels, indicating that blood flow was not compromised at this early stage, Short-term follow-up revealed no signs of progression of the vasculopathy, focal ischemia, gangliothalamic atrophy, or neurological impairment, Nevertheless, the implications of this finding with respect to the natural history of NLE remain to be defined, particularly in cases in which the disease develops into systemic lupus erythematosus later in life, Besides specific diagnostic studies for NLE, cerebral ultrasound, and CDFI studies are mandatory in all cases of complete congenital heart block, regardless of whether mothers are diagnosed as having connective-tissue disease or not, Neonates with signs of vasculopathy in the gangliothalamic region should be examined for NLE.
