Regression of fetal cerebral abnormalities by primary cytomegalovirus infection following hyperimmunoglobulin therapy.

Objective: To assess the effects of maternal and intra-amniotic hyperimmunoglobulin (HIG) infusions among cytomegalovirus (CMV) infected fetuses with ultrasound abnormalities following a primary CMV infection.

Patients And Methods: The subjects were fetuses with CMV-associated cerebral and other ultrasound abnormalities. Three mothers were treated with HIG infusions during pregnancy and two were untreated.

T cell mediated immune responses to Toxoplasma gondii in pregnant women with primary toxoplasmosis.

The aim of this study was to investigate T cell immunity to Toxoplasma gondii (Tg) in pregnant women with primary toxoplasmosis. This issue has never been addressed before in humans and available information derives from murine models. Peripheral blood mononuclear cells (PBMC) from pregnant women with primary Tg infection were stimulated with Tg tachyzoites, excretory-secretory antigens (ESA) or recombinant surface antigen-1 (rSAG-1), and tested for proliferation, immunophenotype, cytokine production and antigen specific cytotoxic activity.
