Detailed Description

The purpose of the study is to compare the Fibroscan results of preeclamptic women to normal controls and to find out if the changes are reversible after labor.

Materials and Methods This prospective observational case-control study will include 50 women admitted to the fetal-maternal Unit at 24 - 41 weeks gestation and diagnosed with mild/severe preeclampsia. Preeclampsia is diagnosed as a new onset of hypertension over 140/90, at least two measurements at least four hours apart, and proteinuria (≥+1 in dipstick or >300 mg/24 hr) after 20 weeks of gestation in a previously normotensive woman.

A control group will consist 100 normotensive women with normal pregnancy outcomes who were admitted to our fetal-maternal unit during the same period. Demographic, clinical, laboratory and sonographic data for the women participating will be collected from their chart. All patients diagnosed with preeclampsia will undergo the following workup: sign and symptoms evaluation, blood pressure follow up, 24-hour protein excretion in grams per day, complete blood count, hepatic function test: AST, ALT and coagulation study, HBA1C, coagulation function test and fibrotest. The Fibroscan test will be performed by a trained hepatologist, who was blind to the women diagnosis. The fibroscan test will be done during the admission after the diagnosis of preeclampsia, after delivery and 6 weeks post-partum.

Commonly used cutoffs are >7 kPa for significant fibrosis. Statistical analysis will be performed with SPSS using Mann Whitney test. Continuous variables will be analyzed using the student's T test and categorical variables were analyzed using 2. Statistical significance was set at a P value of < 0.05. The local institutional review board approved this study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Control group
A control group will consist 100 normotensive women with normal pregnancy outcomes who were admitted to our fetal-maternal unit during the same period
Preeclampsia group
All patients diagnosed with preeclampsia will undergo the fibroscan test.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparing the Fibroscan results of preeclamptic women to normal controls and to find out if the changes are reversible after labor. Fibrotic tissue differs from healthy tissue in the way it responds to excitation
Time Frame: 2 years
Transient elastography is performed using transducer-induced vibrations at low frequency (50 Hz) and amplitudes. The transmitted shear waves propagate through the liver parenchyma. Pulse-echo ultrasound acquisition is used to follow the propagation of the shear wave and to measure its average speed. Results are expressed in kPa and can range from 2.5 to 75 kPa. Commonly used cutoffs in clinical settings are >7 kPa for significant fibrosis and >11 to 14 kPa for cirrhosis and CAP>270 db/m2 for significant steatosis.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 5, 2017

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
