OBJECTIVE To analyze the electrocardiograms (EKGs) of infants born to mothers with anti-SSA/Ro antibodies in order to evaluate the QT interval (the time from the beginning of the QRS complex to the end of the T wave). METHODS Sera from mothers and children were analyzed for anti-Ro and anti-SSB/La antibodies by enzyme-linked immunosorbent assay (ELISA) and by Western blot analysis. Fine specificity of anti-Ro antibodies was evaluated by solid-phase ELISA against recombinant 52- and 60-kd… CONTINUE READING
