  • Preeclampsia

Purpose:

The investigators intend to perform a large prospective study looking at the predictability of the random urine protein-to-creatinine ratio compared to the gold standard 24-hour urine protein collection. Furthermore, the investigators plan to investigate whether analysis of proteinuria at shorter time intervals (4 and 8 hours) within the overall 24-hour collection period is predictive of the 24-hour sample. Lastly, the investigators plan to determine whether a combination of the random test with a shorter collection interval is comparable to the 24-hour collection.


Study summary:

Preeclampsia affects approximately 5-8% of pregnancies in the United States with approximately 10% occurring before 34 weeks gestation. The diagnosis of preeclampsia is determined by the presence of hypertension with proteinuria after 20 weeks gestation. The gold standard for measuring proteinuria is a 24-h urine collection for total protein. In the non-pregnant patient, a random urinary protein-to-creatinine ratio has been shown to be a reliable indicator of significant proteinuria. The reliability of this test remains unclear in the pregnant population. Because there are relatively few studies in the pregnant population and many of these studies were poorly designed, limited by sample size, or confounded by other variables, further research in this area is still necessary. The purpose of this study is to determine if there are alternative diagnostic tools for the quantification of total protein excretion in 24-hours to aid in the diagnosis of preeclampsia that can be performed more quickly and efficiently than the gold standard 24-hour urine collection. We intend to perform a large prospective study looking at the predictability of the random urine protein-to-creatinine ratio compared to the gold standard 24-h urine protein collection. Furthermore, we plan to investigate whether analysis of proteinuria at shorter time intervals (4 and 8 hours) within the overall 24-h collection period is predictive of the 24-h sample. Lastly, we plan to determine whether a combination of the random test with a shorter collection interval is comparable to the 24-h collection. The goal would be to make the diagnosis of preeclampsia in a more timely fashion to aid in the prevention of maternal and neonatal morbidity and mortality including eclampsia, HELLP syndrome, acute renal failure, pulmonary edema, DIC, IUGR, IUFD, intracranial bleeding and stroke, Additionally, an earlier diagnosis could also impact patient care by reducing hospital stay, nursing demands, and eliminating the need for cumbersome and likely inaccurate patient 24-h home collections.
