OBJECTIVE: The maternal syndrome of preeclampsia has been attributed to a systemic intravascular inflammatory response and endothelial cell dysfunction. The stimulus responsible for intravascular inflammation in preeclampsia has not been determined, The expression of CD45 isoforms on the surface of human T cells has been used to classify CD4(+) T lymphocytes into naive cells (CD45RA+) and memory T cells (CD45RO+). An increased percentage of CD45RO+ cells has been interpreted as consistent with previous exposure to microbial products or other antigens. The purpose of this study was to determine whether preeclampsia is associated with a change in the proportion of CD45RA+ and CD45RO+.STUDY DESIGN: A prospective study was conducted in patients with preeclampsia (n = 24) and normal pregnancy (n = 75), The percentage of CD45RA+ and CD45RO+ on CD4(+) T lymphocytes in peripheral blood was determined using flow cytometry and monoclonal antibodies. Results were reported as a percentage of CD4(+) lymphocytes. Parametric statistics were used for analysis. A probability value of
