Management of Suspected Preeclampsia Based on 6-hour Versus 24-hour Urine Protein Collection

October 6, 2020 updated by: Hadas Ganer Herman, Wolfson Medical Center

Management of Pregnancies With Suspected Preeclampsia Based on 6-hour Versus 24-hour Urine Protein Collection - a Randomized Double Blind Controlled Pilot Study

In this trial - the investigators plan to study the efficacy of pregnancy management in cases of suspcted preeclampsia, based on a 6-hour urine collection for protein, as compared to the standard 24-hour collection. For participants hospitalized at the maternal fetal unit at our institution, one sample of urine collected over 6 hours will be analyzed, and a second one following an additional 18 hours. Participants will be blinded to the urine collection result used to manage their pregnancy (actual 24 hour collection versus calculated 24-hour collection), as will be their attending physicians. An external physician will compare the two urine collection results, and in case only one is pathological (>300 mg), will notify the research team and the attending physician.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 55 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Female

Exclusion Criteria:

  • Patients with features of severe preeclampsia at presentation - blood pressure >160/110, headache, blurred vision, right upper quadrant pain, liver transaminase abnormality, increased creatinine level, thrombocytopenia.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Calculated collection
Patients in this arm will collect urine for protein for 6 hours, and then an additional 18 hours. The result of the 6-hour collection will be multiplied by four, and the result will serve as the "calculated collection", for pregnancy management. The additional 18 hour collection will serve for: 1. Patient blinding. 2. Calculation of the total 24-hour protein collection for reference.
Diagnostic test: Six-hour urine protein collection
This intervention includes the analysis of a 6-hour urine collection for protein, to serve for a calculated 24-hour result, according to which pregnancy will be managed.
No Intervention: Control collection
Patients in this arm will collect urine for protein for 6 hours, and then an additional 18 hours. The result of the total 24-hour collection will serve for pregnancy management. The initial 6-hour collection will serve for patient blinding.

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
Number of participants with an adverse maternal outcome composite
Time Frame: Up to 18 weeks
Defined as one of the following maternal complications - hepatic or renal injury, placental abruption, eclampsia, thrombocytopenia, cerebral morbidity, respiratory morbidity, blood pressure > 160/110, need for anti-hypertensives
Up to 18 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of participants whose neonate had an adverse neonatal outcome composite
Time Frame: Up to 18 weeks
