title: [Role of neutralizing antibodies in protection of the fetal from an HIV positive mother].
abstract: The goal of this study is to compare serum Titers of Neutralizing antibodies in HIV 1 infected mothers to the virological status of their newborns. 38 infant-mothers couples were tested. Serum Neutralizing antibodies Titers of the mothers were tested the day of birth. Virological status of new borns was determined by peripheric blood mononuclear cells culture and PCR. 18 Newborns were HIV 1 infected. In 9 cases mothers had no neutralizing antibodies: 7 newborns were HIV 1 infected. In 4 cases mothers had high level of neutralizing antibodies (< 640): none of the newborns was infected. In 25 cases mothers had intermediate value of neutralizing antibodies (between 80 and 320): 11 newborns were HIV 1 infected. Women with neutralizing antibodies to HIV 1, were less likely to transmit HIV 1 to their infants than pregnant women without neutralizing antibodies. Serum neutralizing antibodies titers of pregnant women might be of predictive value in vertical transmission of HIV 1. Further investigations are needed.
