Genital tract infections are linked to spontaneous preterm birth, a major cause of infant mortality and handicap. Antibiotic trials show promise but require further research for effective prevention strategies.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Infectious Diseases

Background:

  • Preterm birth affects 11% of US pregnancies, leading to infant mortality and long-term neurological handicap, particularly in infants born before 32 weeks' gestation.
  • Despite improved survival rates for preterm infants, long-term handicap rates remain unchanged, and preterm birth rates are increasing.
  • Clinically silent upper genital tract infections are implicated in the pathophysiology of spontaneous preterm births, especially early-term births.

Purpose of the Study:

  • To review the current understanding of the relationship between genital tract microbial infections and spontaneous preterm birth.
  • To evaluate the availability and utility of markers for identifying women with genital tract infections.
  • To analyze the results of recent randomized clinical trials of antibiotic therapy for preterm birth prevention.

Main Methods:

  • Review of current literature on genital tract infections and preterm birth.
  • Assessment of diagnostic markers for genital tract infections.
  • Analysis of prospective randomized clinical trials evaluating antibiotic therapy.

Main Results:

  • Genital tract infections are a significant factor in spontaneous preterm birth.
  • Diagnostic markers for these infections have varying degrees of usefulness.
  • Antibiotic therapy trials have yielded mixed results, with specific strengths and limitations.

Conclusions:

  • Further research is needed to refine diagnostic markers and optimize antibiotic treatment strategies.
  • Clinical management strategies require careful consideration of trial evidence and future research directions.
  • Understanding the role of genital tract infections is crucial for reducing preterm birth and associated handicaps.
