[The presence in pregnant women of the risk factor of serum antibodies against 9 viruses with significance in materno-infantile pathology and the transfer of these antibodies to the newborns].

Indirect enzyme immunoassay, performed with Labsystems (Helsinki) kits, in 30 mothers and their newborns, revealed that 100% of parturient women present IgG antibody to hepatitis A (HAV), herpes simplex 1, and measles viruses, constantly transferring these antibodies to their newborns. 78.6% of the women had IgG to rubella (German measles) virus, passively transmitting them to their offsprings. Serological markers (HBsAg and anti-HBc) of hepatitis B virus infection were present in 42% of the investigated women, anti-HBc being also present in the serum of the newborns. Between the identified risk factors (in the past obstetrical history, current pregnancy, labor and early postnatal period) and the spectrum of IgG antibodies present in mothers no significant correlations were revealed. The same obvious lack of correlation between IgG antibodies and risk factors in the neonate (prematurity, low birth weight, malformations) was also found. However, the presence of IgG anti-measles (2 case), IgM anti-rubella (1 case) and IgM and HAV (4 cases) was associated, in the same order, with interstitial pneumonia, hepatosplenomegaly and death, icterus neonatorum, cardiovascular and neurologic malformations. Neither mothers nor their offsprings presented anti-HIV antibodies, suggesting that in the investigated patients no perinatal transmission had occurred.
