Genital CT Treatment to Pregnant Women to Prevent Adverse Pregnancy Outcomes: A Pilot RCT

Not Applicable
Recruiting
Conditions
Chlamydia Trachomatis Infection
Interventions
Diagnostic Test: C. trachomatis and N. gonorrhoeae
Other: Partner notification and treatment
Registration Number
NCT03862495
Lead Sponsor
University of North Carolina, Chapel Hill
Brief Summary

This study aims to identify the relationship between genital C. trachomatis and adverse pregnancy outcomes, and investigate whether screening and treatment of genital C. trachomatis in pregnant women can reduce adverse pregnancy outcomes.

Approximately 200 pregnant women from Nanhai Hospital of Southern Medical University in Guangzhou, China will be enrolled and randomized to the intervention or control group.

Detailed Description

Women recruited for the study will be randomized to the intervention or control groups. Women in the intervention group will be tested in real time for C. trachomatis and Neisseria gonorrhoeae. Patients who test positive for either infection will be linked to physicians at the Center for treatment. For the control group, women will be tested immediately after childbirth or in the event of an adverse pregnancy outcome. In the event of a positive test result, a confirmation test will be run and if positive, the patient will be referred for treatment. The endpoint of the study is defined as either the occurrence of an adverse pregnancy outcome or delivery of a newborn.

Qualitative in-depth interviews will also be conducted with 20 of the women to explore their opinions, attitudes and feedback on the study process. University of North Carolina at Chapel Hill (UNC) investigators will work with the Nanhai Hospital of Southern Medical University and staff at Dermatology Hospital of Southern Medical University to oversee the study.

Chlamydia Screening and TreatmentC. trachomatis and N. gonorrhoeaeAt the time of recruitment and prior to delivery, this group will have immediate testing for C. trachomatis and N. gonorrhoeae. Physicians will notify C. trachomatis positive results to pregnant women and suggest them and their spouses to get treated according to the national standard treatment plan for Chlamydia (Azithromycin 1g, single oral administration). Patients will be followed up to confirm cure of C. trachomatis in one month. Partner notification and treatment will be suggested for pregnant women who test positive for Chlamydia.

ControlC. trachomatis and N. gonorrhoeaeThis group will have testing after delivery (immediately following childbirth) or in the event of an adverse pregnancy outcome for C. trachomatis and N. gonorrhoeae. In the event of a positive test, patients will be informed of the positive test results the same way as the intervention group. Specific treatment options will be the same as the intervention group. Physicians will ask patients to return to Nanhai Hospital one month after treatment for test of cure. Partner notification and treatment will be suggested for pregnant women who test positive for Chlamydia.

Primary Outcome Measures
NameTimeMethod
Response Rate at Recruitmentat the time of enrollment

Number of women who get tested for CT and N. gonorrhoeae (NG) divided by the number of women being contacted about the study at the recruitment

Number of Participants Considered as Cured After Treatment1 or 3 months after the treatment

Number of women who re-tested negative either at 1 or at 3 months after treatment divided by the number of women who received CT or NG treatment

Compliance to Receive CT or NG TreatmentWithin 1 week after the notification of positive test results

Number of women electing to receive CT or NG treatment within 1 week after the notification of positive test results

Number of Participants With Adverse Pregnancy Outcomesthrough study completion, an average of 1 year

Number of any adverse pregnancy outcomes, including stillbirth (a baby who dies after 28 weeks of pregnancy, but before or during birth), fetal death, infant death, miscarriage (pregnancy loss between 12-28 weeks), preeclampsia (pre eclampsia: hypertension with proteinuria occurs after 20 weeks of pregnancy; eclampsia: convulsions that occur on the basis of preeclampsia and cannot be explained by other reasons), low birth weight (\<2500g), smaller than gestational age, preterm birth (\<37 gestational weeks), birth defect, and premature rupture of membrane (spontaneous rupture of fetal membranes before delivery, classified into full-term PROM and preterm PROM based on the gestational age) in both groups through study completion.

Secondary Outcome Measures
NameTimeMethod
