Objective The recurrence rate of anti-SSA/Ro associated congenital heart block (CHB) is 17%. Reversal of 3rd degree block has never been achieved. Based on potential reduction of maternal autoantibody titers as well as fetal inflammatory responses, IVIG was evaluated as a preventative therapy for CHB. Methods A multicenter open-label study based on Simon’s 2-stage optimal design was initiated. Enrollment criteria included: maternal anti-SSA/Ro antibody, a previous child with CHB/rash,

To compare the normal extrahepatic portion of the fetal intra-abdominal umbilical vein (FIUV) with varix of the FIUX, we prospectively measured the diameter of the FIUV in 150 uncomplicated second and third trimester pregnancies and compared these results with retrospective review of nine fetuses with varix of the FIUV as an isolated prenatal sonographic finding. The diameter of the normal FIUV increases linearly from approximately 3 mm at 15 menstrual weeks to approximately 8 mm at term (R = 0.92). The nine fetuses with FIUV varix had a FIUV diameter 6 to 12 standard deviations above the mean for age. Four (44%) of the nine fetuses with FIUV varix subsequently died, including one with trisomy 21. One of the remaining fetuses developed severe hydrops 2 weeks after the initial detection of the FIUV varix. FIUV varix appears to carry an increased risk of adverse fetal outcome, including fetal demise.

A high vaginal interleukin-8 concentration, abnormal vaginal Gram stain, absent hydrogen peroxide-producing Lactobacillus, and anaerobic vaginal flora were strongly associated with AF infection among women in preterm labor.
