Detection and Identification of Preeclampsia Via Volatile Biomarkers (DIP)
Preeclampsia is a form of hypertension that is unique to human pregnancy. The incidence of the disease ranges between 2 and 7 percent in healthy nulliparous women. The etiology of preeclampsia is unknown.
Women with preeclampsia may exhibit a symptom complex ranging from minimal BP elevation to derangements of multiple organ systems. The renal, hematologic, and hepatic systems are most likely to be involved.
More than 100 clinical, biophysical, and biochemical tests have been recommended to predict or identify the patient at risk for the future development of the disease.
The results of the pooled data for the various tests and the lack of agreement between serial tests suggest that none of these clinical tests is sufficiently reliable for use as a screening test in clinical practice. As a result there is obviously a great need to develop a novel technology for the early detection of this pregnancy complication before its clinical manifestations appear. An early detection can help in early treatment to prevent or at least minimize the sequel of this disease.
The aim of this project is the early detection of "Preeclampsia" and other pregnancy complications using volatile biomarkers appearing in exhaled breath and/or blood samples, using a simple and inexpensive toll termed NA-NOSE.
Phase-I: The primary phase of this project is the comparison between volatile biomarkers' patterns of pregnant women suffering from "Preeclampsia", pregnant women that are considered to have "Normal Pregnancy", and healthy "Non-Pregnant" women.
Phase-II: The secondary phase of this project is the ability to predict "Preeclampsia", as compared, head-to-head, with other potential predictors used in the current clinical practice.
