Lymphocyte and lymphocyte subset analyses in women with preeclampsia |

PURPOSE: to analyze the relationship of the imune system with preeclamptic pregnancies, comparing lymphocyte and lymphocyte subset analyses of normal pregnant women to pregnancy-induced hypertensive women. To evaluate this immunological function, 40 pregnant women were studied at the "Irmandade da Santa Casa Hospital" of São Paulo: 20 women with normal pregnancies and 20 women with pregnancy-induced hypertension. From all these pregnant women peripheral blood samples were obtained and submitted to the following tests: lymphocyte and lymphocyte subsets analyses (CD4+, CD8+, CD4+/CD8 +CD3+, CD19+). Statistical analysis was performed by the Mann-Whitney test. RESULTS: the serum lymphocyte counts were decreased in women with preeclampsia (preeclamptic group 2295.10±1328.16; control group 3892.80±1430.85, p<0,05); and so were CD4+ (preeclamptic group 1188.80±625.61, control group; 1742.25±628.40, p<0.05); CD8+ (preeclamptic group: 774.00±371.31, control group 1175.70±517.72, p<0,05) and CD3+ (preeclamptic group 1958.65±983.78, control group 2916.95±1117.88, p<0,05). The other tests showed no significant differences between groups. CONCLUSION: the findings indicated a decreased number of lymphocytes, CD4+, CD8+ and CD3+ in preeclampsia.
