OBJECTIVES: To investigate placental transfer of anti-tetanus immunoglobulin (Ig)G antibodies in Iranian mothers. METHODS: Sera collected from 209 pregnant women and their paired infants were evaluated for tetanus-specific antibodies by a commercial enzyme-linked immunosorbent assay. RESULTS: In total, 15 (7.2%) out of 209 mothers and 12 (5.7%) out of 209 newborns were negative for anti-tetanus IgG. A highly significant correlation was observed between maternal and fetal anti-tetanus IgG (r = 0.80). The mean cord/maternal blood ratio of anti-tetanus IgG was 1.22 +/- 0.97. The mean cord/maternal blood ratio of anti-tetanus IgG in mothers with blood groups B+ and AB+ was lower than in mothers with other blood groups (p = 0.027). In addition, among mothers who had more than 0.5 IU/ml anti-tetanus IgG, a higher percentage of cases with cord/maternal blood ratio of < 1 was observed in carriers of blood groups B+ and AB+ compared to those with other blood groups (45.2% vs. 41.8%). Parity of more than 4 had a significant negative effect on both frequency of high positive sera and the mean of anti-tetanus IgG level in maternal and neonatal sera. CONCLUSIONS: A relatively high percentage of pregnant women were not immune against tetanus. It was also found that the main factors that affect infants' tetanus-specific IgG are maternal concentration of this immunoglobulin, parity and maternal blood group.
