RESUMO
Objective To study the association between paternal CD3, CD4 and CD8 antigenecity to their pregnant spouses and the development of pregnancy induced hypertension (PIH). Methods Maternal serum from 15 women with PIH in the third trimester and 82 in normal pregnancies (16 in the first, 32 in the second and 34 in the third trimester) were incubated with paternal T lymphocytes. Monoclonal CD3, CD4 and CD8 fluorescent conjugated antibodies were then added and the percentage of paternal T cell differentiation antigen CD3, CD4 and CD8 were measured by flow cytometry. Results During normal pregnancy, the levels of maternal serum blocking antibodies on paternal CD3, CD4 and CD8 were (4.14?1.02, 2.02 ?0.24, 2.37?1.05)% in first trimester, (-0.29?0.13, 1.03?0.27, 0.65?0.23)% in the second trimester and (-1.33?1.47,0.15?0.01, -1.04? 0.37)% in the third trimester. There were significant difference between them( P
