調査対象母集団
Affected Group: Pregnant women diagnosed with preeclampsia with severe features or fetal growth restriction
Control group: Pregnant women matched for gestational age to the Affected group above
説明
Inclusion Criteria:
- Women 18 years of age or older at enrollment
- Pregnant women with a viable singleton gestation
- Able to provide written, informed consent
- Able to provide 20 mL of whole blood
Diagnosis of preeclampsia with severe features and/or diagnosis of fetal growth restriction.
Preeclampsia with severe features is defined as:
Proteinuria: Excretion of ≥300mg/24hr (24 hour collection) of protein or a timed excretion that is extrapolated to the 24 hour urine value or a protein/creatinine [both in mg/dL] ratio of at least 0.3 or a qualitative determination of (urine dipstick) of ≥1+ WITH Systolic BP ≥160mmHg or diastolic BP ≥110mmHg on at least 2 occasions 4 hours apart while on bedrest but before the onset of labor OR Systolic BP ≥160mmHg or diastolic BP ≥110mmHg on 1 occasion but before the onset of labor, if antihypertensive therapy is initiated due to severe hypertension OR New onset hypertension defined as: Systolic BP ≥140 mmHg or diastolic ≥90 mmHg with one or more of the following features: Thrombocytopenia (<100,000 plts/mL); impaired liver function (AST/ALT 2X ULN); newly developed renal insufficiency (serum creatinine >1.1mg/dL or a doubling of serum creatinine in the absence of other renal disease); pulmonary edema; new onset cerebral disturbances or scotomata
- Fetal Growth Restriction defined as:
Estimated fetal weight by ultrasound at ≥ 19 0/7 weeks gestational age < 5%ile or 5-10%ile with abnormal umbilical artery Doppler examination (S/D ratio >95%ile for gestational age, absent end diastolic flow or reverse end diastolic flow)
- Gestational age between 20 0/7 and 33 6/7 weeks determined by ultrasound and/or LMP per ACOG guidelines1. A subject diagnosed with preeclampsia without severe features prior to 33 6/7 weeks gestation and who is managed expectantly and develops severe features after 34 weeks may be included.
Exclusion Criteria:
- Known malignancy
- History of maternal organ or bone marrow transplant
- Maternal blood transfusion in the last 8 weeks
- Chronic hypertension diagnosed prior to current pregnancy
- Type I, II or gestational diabetes
- Fetal anomaly or known chromosome abnormality
- Active labor
