ABSTRACT
Objective To investigate the clinical significance of serum transforming growth factor-β( TGF-β),tumor necrosis factor-α( TNF-α) and interferon-γ( IFN-γ) levels in patients with pre-eclampsia. Methods Thirty-two cases of maternal pre-eclampsia( 22 cases were mild pre-eclampsia,10 cases were severe pre-eclampsia),30 cases of gestational hypertension and 30 cases of normal mothers were selected as our subjects. Serum TGF-β,TNF-α IFN-γ levels were detected. Adverse pregnancy outcomes in patients were collected and analyzed. Results Serum TGF-β,TNF-α,IFN-γlevels in patients with severe pre-eclampsia were (90. 4 ± 23. 4)μg/L,(84. 5 ± 13. 6)μg/L and(146. 5 ± 13. 4)μg/L respectively,significantly higher than that in normal mothers((11. 3 ± 3. 7)μg/L,(5. 6 ± 1. 2)μg/L and(82. 5 ± 19. 4)μg/L),the gestational hypertension group(( 35. 3 ± 8. 4 )μg/L,( 10. 4 ± 2. 9 )μg/L and( 96. 4 ± 15. 8 )μg/L ),and mild pre-eclampsia group((76. 5 ± 15. 4)μg/L,(26. 5 ± 3. 2)μg/L and(120. 4 ± 20. 5)μg/L),and the difference were significant(F=11. 363,15. 982,7. 431;P﹤0. 001). Serum TGF-β,TNF-α and IFN-γ levels in mild pre-eclampsia were significantly higher than those in normal mothers and gestational hypertension patients( P﹤0. 05). Incidence of preterm delivery in patients with high TGF-β,TNF-α,IFN-γ expression was significantly higher than patients with low expression(7 cases vs. 2 cases;χ2 =4. 037,P=0. 044). Incidence of in patients with high FGR,TGF-β,TNF-α expression was significantly higher than patients with low expression( 6 cases vs. 1 case;χ2 =4. 969,P =0. 025 ). Conclusion Detection of maternal serum cytokines can evaluate the severity of pre-eclampsia to a certain extent and predicted adverse pregnancy outcomes.
