Brief Summary: This proposal has three aims to characterize the relationship between aspirin therapy, platelet function response, and prevention of hypertensive disorders of pregnancy (HDP) through a prospective, cohort study using pharmacokinetics, pharmacodynamics, pharmacogenomics and bioinformatics. The results of this proposal will provide necessary data for prospective study on individualized aspirin dose adjustment for prevention of HDP.
Detailed Description: This proposal has four aims to characterize the relationship between aspirin therapy, platelet function response, and prevention of HDP through a prospective, cohort study using pharmacodynamics, pharmacogenomics and bioinformatics. The results of this proposal will provide necessary data for prospective study on individualized aspirin dose adjustment for prevention of HDP.

Aim 1: Establish pharmacodynamic endpoints for aspirin in prevention of HDP Hypothesis: PFA-100 closure time and serum thromboxane/urinary dehydrothromboxane-B2 (dTX-B2) are pharmacodynamic markers of aspirin response and are predictive of HDP high risk pregnant patients.

Aim 2: Explore aspirin pharmacogenetics by assessing the relationship between platelet receptor genotype, aspirin response, and prevention of HDP Hypothesis: Platelet receptor genotype is associated with race and may result in reduced platelet response to aspirin therapy, and increased incidence of HDP.

Aim 3: Assess the utility of circulating microRNA as a marker of aspirin response in pregnancy and risk of HDP Hypothesis: Quantitative expression of selected miRNAs are biomarkers for response to aspirin therapy and risk of HDP.

Aim 4: Evaluate aspirin pharmacokinetics/pharmacodynamics Hypothesis: Individual factors influence aspirin pharmacokinetics/pharmacodynamics and may impact individual dosing of aspirin
