Antenatal Corticosteroid Therapy: Which Impact on Birth Parameters?

December 8, 2022 updated by: RENARD Emeline, Central Hospital, Nancy, France

Use of antenatal corticosteroids therapy has increased since the 2000s. The benefits of such a therapy on premature newborns are scientifically and internationally recognized.

Nevertheless, few studies have been conducted to investigate the impact of this antenatal corticosteroid therapy on full-term newborns (> 36 weeks' gestation).

The aim of this study is to compare the birth parameters of full-term newborns exposed or not to antenatal corticosteroid therapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

All children included in the study were born at the Regional Maternity Hospital of Nancy between January 1, 2014 and December 31, 2020.

One hundred and twenty-one of them were exposed during pregnancy to antenatal corticosteroids therapy and constitute the exposed arm, whereas 242 were not and constitute the non-exposed arm.

Data were collected retrospectively regarding history of pregnancy, birth parameters and neonatal adaptation.

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

Study Population

All children included in the study were born at the Regional Maternity Hospital of Nancy between January 1, 2014 and December 31, 2020.

One hundred and twenty-one of them were exposed during pregnancy to antenatal corticosteroids therapy and constitute the exposed arm, whereas 242 were not and constitute the non-exposed arm.

Description

Inclusion Criteria:

  • all children exposed to an antenatal corticosteroid therapy before 34 weeks of amenorrhea because of a threat of premature delivery
  • only full-term newborns

Exclusion Criteria:

  • all children exposed to an antenatal corticosteroid therapy before 34 weeks of amenorrhea for other reasons

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.
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.
exposed group (121 patients)

Extrated from the population of full-term newborns (> 36 weeks of amenorrhea + 6 days) between 2014 and 2020 at the Regional Maternity Hospital of Nancy who received at least one course of betamethasone before 34 weeks of amenorrhea for a threat of preterm delivery.

Exposure to an antenatal corticosteroid therapy was defined as the administration of at least one course of betamethasone (i.e. two doses of 12 mg, 24 hours apart). in intramuscular, before 34 weeks of amenorrhea, for a threat of premature delivery.
Drug: Betamethasone
nonexposed group (242 patients)
came from the population of full-term newborns (> 36 weeks of amenorrhea + 6 days) between 2014 and 2020 at the Regional Maternity Hospital of Nancy who who had not been exposed to antenatal steroid therapy. Two controls were selected for a case, appaired on the month and year of birth and on the sex of the case patient.

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.

Time Frame: Birth

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.

January 1, 2014

Primary Completion (Actual)

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.
