Humoral immunity status in neonates born to pre-eclamptic toxaemia mothers.

ABSTRACT

A prospective study on 90 neonates born to age matched normal mothers (set I) and mothers (set II) with pre-eclamptic toxaemia (PET) was undertaken to assess and compare the humoral immunity status of the neonates. All of them had normal vaginal delivery. IgG, IgA and IgM were estimated by radial immunodiffusion technique from cord blood of neonates. It was observed that IgA and IgM levels were insignificant in the cord blood. IgG level was low in normal birth weight (NBW) neonates born to PET mothers, when compared to that of NBW neonates born to normal mothers. Again low birth weight (LBW) babies of both the sets showed lower values of IgG than that of NBW babies. Apgar scoring showed direct relationship with IgG levels e.g., higher the Apgar score higher the level of IgG. Thus the IgG level was directly related to the birth weight of the neonates of the respective sets as well as with the Apgar scoring of the neonates.
