Trial summary

The investigators hypothesized that the IL-1A (+4895), IL-1B (+3954), and IL-1RN gene polymorphisms may be associated with PLBW. Smoking has been well documented by numerous studies as a major environmental risk factor for periodontitis and adverse pregnancy outcomes. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 35 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Study population: Pregnant women between 18-35 years of age with single gestation and with ≥20 on-crowded teeth excluding third molars were included in this study. Subjects were divided into normal birth (NB) and PLBW groups on the basis of their pregnancy outcome. Women who delivered an infant with a birth weight of more than 2500 g after 37 weeks of gestation were placed in the NB group. Women who delivered infants whose birth weight was below 2500 g or before 37 weeks of gestation were placed in the PLBW group.

Who may be able to join

  • Subjects were divided into normal birth (NB) and PLBW groups on the basis of their pregnancy outcome. Women who delivered an infant with a birth weight of more than 2500 g after 37 weeks of gestation were placed in the NB group.

Who cannot join

  • Current/past tobacco user, alcohol abuse, history of high-risk gestation, hypertension, gestational diabetes, any systemic disease and placenta previa were the exclusion criteria for this study.

About this study

The investigators hypothesized that the IL-1A (+4895), IL-1B (+3954), and IL-1RN gene polymorphisms may be associated with PLBW. Smoking has been well documented by numerous studies as a major environmental risk factor for periodontitis and adverse pregnancy outcomes. Therefore, the investigators only selected non-smoking individuals in this study as the smoking-related risk could obscure the polymorphism-related increase in risk for periodontitis and adverse pregnancy outcomes. This study aimed to determine the association between IL-1A (+4895), IL-1B (+3954), and IL-1RN polymorphisms with adverse pregnancy outcomes and periodontitis in a non-smoking Turkish population.

Read the detailed description

Pregnant women between 18-35 years of age with single gestation and with ≥20 on-crowded teeth excluding third molars were included in this study. Subjects were divided into normal birth (NB) and PLBW groups on the basis of their pregnancy outcome. Women who delivered an infant with a birth weight of more than 2500 g after 37 weeks of gestation were placed in the NB group. Women who delivered infants whose birth weight was below 2500 g or before 37 weeks of gestation were placed in the PLBW group. Current/past tobacco user, alcohol abuse, history of high-risk gestation, hypertension, gestational diabetes, any systemic disease and placenta previa were the exclusion criteria for this study. Maternal, obstetric, and demographic factors such as maternal age, maternal education, regular prenatal care, genitourinary tract infections during pregnancy, total number of births, previous PLBW, and antibiotic use during the pregnancy period were also recorded.

Questions about this trial

What is this clinical trial studying?

An observational study of Periodontitis, run by Selcuk University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Interleukin-1 receptor antagonist gene polymorphism and adverse pregnancy outcome in Turkish women (time frame: 5 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2013.
