Abstract

The lymphocyte blastogenic response to a panel of antigens and mitogens was assessed in a group of 20 women throughout their pregnancy. In addition, a group of five nonpregnant women was monitored simultaneously to identify variations in response to the same stimulants. The stimulants included orally associated bacterial antigens (Streptococcus sanguis, Actinomyces viscosus, Bacteroides asaccharolyticus, Bacteroides melaninogenicus subsp. intermedius, Bacteroides [Capnocytophaga] ochraceus, and Fusobacterium nucleatum) and non-orally associated-stimulants (streptokinase-streptodornase, tetanus toxoid, concanavalin A, phytohemagglutinin, and pokeweed mitogen). Intrinsic (cells cultured in male AB plasma) suppression of the lymphocyte response to these stimulants was observed to occur by the second trmester of pregnancy and was resolved after parturition. Additionally, an extrinsic (cells cultured in autologous plasma) suppression was also suggested to occur in a similar manner. There was no detectable enhancement of the blastogenic response to oral bacteria associated with elevated gingivitis, which is generally reported to occur during nonpregnancy gingivitis. We propose that concomitant immunosuppression occurs during the second trimester, which masks such enhancement.
