Objective To investigate the role of subtype 1 autoantibody against angiotensin Ⅱ receptor in the pathogenesis of preeclampsia by detecting its expression in the peripheral blood of preeclampsia patients,Methods Thirty patients with preeclampsia were assigned to preeclampsia group. Twenty normal pregnant women at the late stage and twenty non-pregnant healthy women as controls were investigated. The level of type 1 antoantibody against angiotensin Ⅱ in the peripheral blood was detected by indirect SA-ELISA assay with the produced ATR-1 as the antigen. Results The level of subtype 1 antoantibody against angiotensin Ⅱ (65 ±4. 7) % in the peripheral blood of preeclampsia patients is significantly higher than that of normal late pregnant (26 ±2. 8)% and non-pregnant women(7.8 ±2. 2)% groups (t1 =24. 97 ;t2 =38.56;P ＜0. 01 for both) ;The angiotensin Ⅱ receptor subtype 1 autoantibody in the group of normal late pregnancy (26 ± 2. 8 )% was significantly higher than that of healthy non-pregnant women group ( 7. 8 ± 2. 2 ) % ( t = 4. 58, P ＜ 0. 05 ).Conclusion Compared with the normal pregnant women and the healthy non-pregant women, the autoantibody against AT1 receptor in sera of preeclamptic patients is elevated ata high frequency. These results suggest that overproduction of AT1-AA may play an important role during the development of preeclamptic patients. AT1-AA is a novel risk factor in pregnant women. Immune mechanisms may be involved in the process of pregnancy.
