[Analysis of serum lipid and apolipoprotein levels in pregnancy-induced hypertension and normotensive pregnant women].
OBJECTIVE
To investigate the serum lipid and apolipoprotein levels in pregnancy-induced hypertension (PIH or pre-eclampsia), normotensive pregnant women and non-pregnant women.


METHODS
Twenty-eight women with PIH, 31 normatensive and 24 non-pregnant ones were studied, from whom maternal blood samples were collected. Serum lipid levels were measured by enzymatic method and apolipoproteins AI, B100, C II, CIII and E levels by radial immunodiffusion kits developed by our Lab.


RESULTS
1. Serum TG, apoC II and apoC III were highly increased in normotensive pregnant women by 3.5, 2.4 and 2.8 times respectively, when compared with those in non-pregnant ones (P < 0.001); serum TC, nHDL-C and apoAI, B100 and E were also increased in normotensive pregnant women by 21%, 33%, 55%, 79% and 77% respectively, when compared with those in non-pregnant ones (P < 0.001). TG/HDL-C in normotensive pregnant women was also significantly, higher than that in non-pregnant ones(P < 0.01). Serum HDL-C levels remained unchanged in both groups. 2. Serum TG, apoC II and apoC III were highly increased in PIH patients by 2.3, 4.0 and 2.8 times respectively, when compared with those in non-pregnant ones (P < 0.001); serum TC, nHDL-C and apoAI, B100 and E were also increased in PIH patients by 27%, 26%, 52%, 90% and 67% respectively, when compared with those in non-pregnant ones (P < 0.001) TG/HDL-C in PIH patients was also significantly higher than that in non-pregnant ones (P < 0.01). Serum HDL-C levels were increased in PIH patients by 29%, when compared with non-pregnant women. Only serum HDL-C level in PIH patients was higher than that in normotensive pregnant women. No significant differences were seen in other lipid and apolipoprotein levels between PIH patients and normotensive pregnant ones. 3. There was no significant difference in the levels of serum lipid and apolipoprotein between the subgroups of PIH patients according to the severity of the disease.


CONCLUSIONS
The increase of serum lipid and apolipoprotein levels in PIH is probably not the predictor for pre-eclampsia.
