Aspirin Treatment Effective Against Pre-eclampsia – But Must Be Started Early

Guidelines on pre-eclampsia prevention in various countries (e.g. Australia, Canada, France, Germany, Italy, UK) recommend the administration of low-dose aspirin in all pregnancies that are at risk, starting during the first trimester, or at least before week 16. In addition, Calcium is recommended for women with low dietary intake/calcium deficiency in local guidelines in France, Australia and New Zealand for pre-eclampsia prevention.

Treatment with low doses of aspirin (acetylsalicylic acid, ASA) during pregnancy has been shown to reduce the risk of pre-eclampsia. Although meta study data initially suggested that the benefits are modest (Duley, 2007), it is now understood that the time at which aspirin treatment is commenced is of principle importance (Bujold, 2010). The inclusion of results from pregnancies where aspirin has been administered at a late stage of pregnancy compromised the earlier meta-studies, and hid the clear benefit that administration before 16 weeks provides. In a recent meta study (Roberge et al, 2012) it was concluded that low-dose aspirin administrated at or before 16 weeks of gestation provides an 89% reduction in the risk of pre-eclampsia that necessitates delivery before 37 weeks. Research into the efficacy of aspirin therapy continues and should only be pursued at the direction of a medical professional.
