Brief Summary:
This is a prospective cohort, enriched with women with a prior term birth, of singleton pregnancies who will be followed for the outcome of preterm birth. The main exposure of interest is the characterization of the cervico-vaginal microbiota. Women will be recruited from a population seeking routine obstetrical care at obstetrical practices at Penn. They will have three research visits during pregnancy to complete questionnaires and collect samples of cervico-vaginal fluid and cervical cells. Outcome data will be collected about the prenatal events and timing of delivery.

Condition or disease
Preterm Birth

Detailed Description:
Patients will be recruited around the time of their routine obstetrical visits. They will be asked to participate in three visits total. Visit one/enrollment occurs between 16 and 20 weeks of gestation, visit two at 20-24 weeks, and visit three at 24-28 weeks. At each visit, vaginal swabs will be collected. The patient will also be asked to fill out a series of surveys related to stress, anxiety,and depression in pregnancy. Research coordinators will perform chart abstraction after delivery.

Study Type : Observational
Actual Enrollment : 2000 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Revealing the Role of the Cervico-vaginal Microbiome in Spontaneous Preterm Birth
Study Start Date : October 2013
Actual Primary Completion Date : February 3, 2017
Actual Study Completion Date : June 1, 2017

Prior Preterm Birth Patients
All obstetrical patients eligible for the study that have had a prior preterm birth.
Term Birth Patients
All obstetrical patients eligible for the study that have not had a prior preterm birth.

Primary Outcome Measures :
  1. Cervicovaginal Microbiota in Women With and Without Preterm Birth [ Time Frame: Enrollment through delivery ]
    Cervicovaginal Microbiota in Women With and Without Preterm Birth

Secondary Outcome Measures :
  1. Potential Modifiers of the Cervicovaginal Microbiome [ Time Frame: Enrollment through delivery ]
    Potential modifiers of the cervicovaginal microbiome: behavioral factors, stress, nutrition/obesity, vaginal infections, genetic or host immune differences, race and ethnicity, social behaviors, environmental influences

Biospecimen Retention:   Samples With DNA

Women will self-collect samples of their cervicovaginal fluid using large cotton swabs.

Subjects who have had a previous preterm birth will also have cervical cells collected in the same manner that cells are collected for a routine pap smear.

Ages Eligible for Study:   13 Years to 50 Years   (Child, Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Pregnant women will be recruited from three locations: Penn ObGyn Associates, Helen O. Dickens Clinic, and Maternal Fetal Medicine at 2000 Courtyard. Potential subjects will be identified from clinical schedules and will be pre-screened in EPIC for eligibility. They may be approached during a clinical visit, or the research team may call them prior to or after a scheduled visit to introduce the study. Women can be enrolled anytime between the confirmation of pregnancy and 20 weeks/0 days gestation. For convenience, research visits can be conducted at the time of a scheduled clinical visit, or at a separate time.

Inclusion Criteria:

- Pregnant women receiving care in University of Pennsylvania Health System

Exclusion Criteria:

  • Non-singleton pregnancy (twins, triplets, etc.)
  • Known major fetal anomaly
  • Known HIV positive status
  • History of organ transplant
  • Chronic steroid use (greater than 20 mg per day for more than 30 days at the time of first study visit)
