Maternal High Blood Pressure and Newborn's Blood Profile (MPIHHPN)

August 26, 2017 updated by: Alexandru Florin Rogobete, Romanian Society of Anesthesia and Intensive Care

Maternal Pregnancy Induced Hypertension and Hematological Profile of Newborns

Maternal high blood pressure remodels the intrauterine environment of the fetus by altering hormonal and cellular signaling patterns and, as a result increases the risk of fetal and neonatal mortality and morbidity. Newborns of these mothers have an increased risk of intrauterine growth restriction, premature birth and hematological abnormalities, such as thrombocytopenia, polycythemia, and neutropenia. The purpose of the article is to review neonatal thrombocytopenia and neutropenia as a consequence of maternal high blood pressure and to establish the optimal management of these cases.

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.

Detailed Description

Pregnancy induced hypertension (PIH) and preeclampsia (preE) are caused by gestation and have an onset after 20 weeks of pregnancy. Although the exact etiology of PIH and preE remains unknown, two interconnected mechanisms have been identified to play an important role in the pathogenesis: dysfunction of the placental trophoblast and endothelial dysfunction within the maternal systemic vasculature. The endothelium has been identified as the target tissue of the disease. Endothelial alterations ultimately manifest as placental hypoxia and hypoplasia. The neonatal thrombocytopenia and neutropenia after pregnancy-induced hypertension is a result of inhibition of fetal bone marrow production of the myeloid lineage due to intrauterine hypoxic environment. This study aims to investigate the hematological profile in term and preterm infants born to mothers with preeclampsia. The current retrospective observational study was conducted at the Clinic of Obstetrics, Gynecology and Neonatology of the Emergency County Hospital, Timisoara over a period of three years, from January 2014 to December 2016. All inborn patient files were analyzed as anonymised limited data sets from archived records of the Neonatology Department.

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

1 day to 4 weeks (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

All newborns admitted to the Neonatology Department who met the Inclusion Criteria.

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.
