Insights

Cefuroxime plus roxithromycin prolonged pregnancy in preterm pre-labor rupture of membranes (PPROM) and reduced gram-negative infections compared to ampicillin plus roxithromycin. This combination is recommended for PPROM management.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Infectious Diseases

Background:

  • Prophylactic antibiotics in preterm pre-labor rupture of membranes (PPROM) reduce intra-amniotic infections and improve neonatal outcomes.
  • Optimal antibiotic regimens for PPROM remain undetermined.
  • Rising rates of early-onset sepsis due to Escherichia coli and Klebsiella pneumoniae, coupled with ampicillin resistance, necessitate evaluating alternative antibiotic protocols.

Purpose of the Study:

  • To compare the efficacy of two prophylactic antibiotic regimens in PPROM: ampicillin + roxithromycin versus cefuroxime + roxithromycin.
  • To evaluate the impact of these regimens on prolonging pregnancy duration.
  • To assess the reduction in infectious morbidity in neonates.

Main Methods:

  • A multicenter, randomized, unblinded, controlled, prospective trial involving 84 women with PPROM.
  • Comparison of two antibiotic prophylactic protocols: ampicillin + roxithromycin versus cefuroxime + roxithromycin.
  • Data collected from December 2015 to December 2019.

Main Results:

  • The cefuroxime + roxithromycin group demonstrated a significantly longer median latency period (4.63 days) compared to the ampicillin + roxithromycin group (2.3 days) (p = 0.039).
  • Rates of neonatal intensive care unit admission, hospitalization length, neonatal respiratory distress syndrome, neonatal fever, and need for respiratory support were similar between groups.
  • Klebsiella pneumoniae cultures were significantly more frequent in the ampicillin + roxithromycin group; no Group B Streptococcus was detected.

Conclusions:

  • Cefuroxime + roxithromycin is recommended as a first-line protocol for PPROM.
  • This regimen effectively prolongs latency and reduces gram-negative early-onset sepsis.
  • The findings support a shift in antibiotic choice for PPROM management.
