- Abstract
It is known that infants with neonatal lupus erythematosus (NLE) may be born to mothers whose sera are positive for the anti-Ro/SSA antibody. However, women who have this antibody do not always give birth to children with NLE. We have demonstrated tubuloreticular structures in vascular endothelial cells in the skin lesions of infants with NLE. Tubuloreticular structures could no longer be detected at the site of the lesions once the annular erythema had resolved, and the anti-Ro/SSA antibody test had become negative. The probability of a child being born with NLE was assessed by observing whether tubuloreticular structures were formed in Daudi cells cultured with sera from eight mothers who were anti-Ro/SSA antibody positive. Tubuloreticular structures formed in Daudi cells cultured with sera from four mothers who bore infants with NLE. but not in Daudi cells cultured with sera from four other mothers who bore normal infants. These results suggest that women who are positive for the anti-Ro/SSA antibody have a higher risk of bearing infants with NLE if tubuloreticular structures are formed in Daudi cells cultured with sera from these women, whereas this risk is lower if tubuloreticular structures do not develop in Daudi cells.
