Chlamydia trachomatis infection and pregnancy outcome
American Journal of Obstetrics and Gynecology
|April 1, 1987
Summary
Chlamydia trachomatis infection in pregnant women did not significantly increase common pregnancy complications. However, recent or invasive infections, indicated by IgM antibodies, were linked to higher rates of preterm delivery and premature rupture of membranes.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Neonatal Health
Background:
- Chlamydia trachomatis is the leading cause of sexually transmitted infections in the U.S.
- Vertical transmission of C. trachomatis to infants is known.
- The impact of C. trachomatis on pregnancy outcomes is debated.
Purpose of the Study:
- To investigate the association between Chlamydia trachomatis infection and adverse pregnancy outcomes.
- To compare pregnancy complication rates in infected pregnant women versus controls.
- To examine if recent or invasive chlamydial infection influences perinatal complications.
Main Methods:
- Prospective study design.
- 270 pregnant women with C. trachomatis compared to 270 matched controls.
- Analysis of pregnancy complications including preterm delivery, PROM, amnionitis, and neonatal sepsis.
- Subgroup analysis based on IgM antibody presence indicating recent/invasive infection.
Main Results:
- No significant differences in overall pregnancy complication rates (preterm delivery, PROM, amnionitis, etc.) between C. trachomatis-infected women and controls.
- In women with recent or invasive chlamydial infection (IgM positive), a statistically significant increase in preterm delivery (p=0.03) and premature rupture of membranes (p=0.03) was observed.
- Rates for premature rupture of membranes, preterm delivery, amnionitis, intrapartum fever, small for gestational age, postpartum endometritis, and neonatal sepsis were not significantly different between cases and controls.
Conclusions:
- Overall Chlamydia trachomatis infection in pregnancy is not associated with a statistically significant increase in major adverse outcomes.
- Recent or invasive chlamydial infections, identified by IgM antibodies, may be associated with increased risk of preterm delivery and premature rupture of membranes.
- Further research is warranted to clarify the specific risks associated with different stages of chlamydial infection during pregnancy.
