Pre eclampsia

I've had high blood pressure/pre eclampsia during both pregnancies - DD1 was born 4 weeks early, and DS 9 weeks early.

Has anyone suffered from this and then gone on to have a 'normal' pregnancy?? Me and hubbie are both very broody!

I had pre-eclampsia in my first pregnancy and then went on to have 2 further normal pregnancies. I think that it does make a big difference though if you have it in second pregnancy. It is common in first but not so much in subsiquant ones. Hope this hlps a little bit x x x.

Hi Hattsmum,

DW (primie) developed PIH at around 31 weeks, and later, as the BP went a bit mad, we saw a private consultant and subsequently had a c-s at 36 weeks due to IUGR / degraded placenta etc.

I don't think dw developed PE, but I asked the consultant and there are proposed treatments to reduce the chance of subsequent PE / bp issues in your pg - things like aspirin, Vit C, mag. sulphate etc.(IIRC - please check !) I think it might be worth asking what is the latest research and any proposed therapies which might be relevant to your next pg.

Good luck !

Thanks, I will check what the latest research advises

You could also drop a sly e-mail to one of the consultant's secretaries if you just want a pointer to the latest research or a summary of what treatment they might propose perhaps.

Good luck.

I think the US in particular is keen on mag. sulphate therapy as a precautionary treatment for PE. Perhaps a
'PE prevention' google might yield something useful ?

Tomy are currently doing a clinical trial on Vit C and E to reduce incidence of pre-enclampsia. To get on the trial you have to be less than 20 weeks pregnant and in a high risk group. Half the group get the real thing 1000mg Vit C and 400 Vit E, and the other half get a placebo.

Interesting, goldenoldie. Do you know if the trial is using any additional drugs / variables (say aspirin, higher / longer doses of folic acid, magnesium sulphate etc.) or just the two vits you posted ?

goldenoldie · 28/07/2005 19:13

As far as I know it is just the two vits - nothing else.

This is the study (published in the Lancet in 1999) they are trying to replicate on a bigger scale to see if they get the same significant reduction in PE with it C & E.

Effect of antioxidants on the occurrence of pre-eclampsia in women at increased risk: a randomised trial.

BACKGROUND: Oxidative stress has been implicated in the pathophysiology of pre-eclampsia. This randomised controlled trial investigated the effect of supplementation with vitamins C and E in women at increased risk of the disorder on plasma markers of vascular endothelial activation and placental insufficiency and the occurrence of pre-eclampsia.

METHODS: 283 women were identified as being at increased risk of pre-eclampsia by abnormal two-stage uterine-artery doppler analysis or a previous history of the disorder and were randomly assigned vitamin C (1000 mg/day) and vitamin E (400 IU/day) or placebo at 16-22 weeks' gestation. Plasma markers of endothelial activation (plasminogen-activator inhibitor 1 [PAI-1]) and placental dysfunction (PAI-2) were measured every month until delivery. Pre-eclampsia was assessed by the development of proteinuric hypertension. Analyses were done by intention to treat, and in the cohort who completed the study.

FINDINGS: Supplementation with vitamins C and E was associated with a 21% decrease in the PAI-1/PAI-2 ratio during gestation (95% CI 4-35, p=0.015). In the intention-to-treat cohort, pre-eclampsia occurred in 24 (17%) of 142 women in the placebo group and 11 (8%) of 141 in the vitamin group (adjusted odds ratio 0.39 [0.17-0.90], p=0.02). In the cohort who completed the study (81 placebo group, 79 vitamin group), the odds ratio for pre-eclampsia was 0.24 (0.08-0.70, p=0.002).

INTERPRETATION: Supplementation with vitamins C and E may be beneficial in the prevention of pre-eclampsia in women at increased risk of the disease. Multicentre trials are needed to show whether vitamin supplementation affects the occurrence of pre-eclampsia in low-risk women and to confirm our results in larger groups of high-risk women from different populations.
