Fetal immune response following maternal diphtheria during early pregnancy.
A pregnant Sudanese woman contracted pharyngeal diphtheria during the first trimester of gestation. She had a severe diphtheritic toxaemia and paralysis of all four limbs but made a full recovery from these manifestations. Pregnancy, apart from vaginal bleeding, was not interrupted. At term she was delivered of a female baby who was physically normal but had a very high level of IgA in cord blood. Diphtheria in adults is a rare disease and the occurrence of diphtheria in a pregnant woman has not, as yet, been reported. Accordingly it is not known how fetal growth and development progress in the presence of diphtheria toxin in the maternal circulation. Similarly the effects on fetal immune responses of an acute maternal infection like diphtheria occurring in early pregnancy are not known.
