Intraamniotic infection with genital mycoplasmas exhibits a more intense inflammatory response than intraamniotic infection with other microorganisms in patients with preterm premature rupture of membranes.
OBJECTIVE
The objective of the study was to compare the intensity of inflammatory responses between intraamniotic infection with genital mycoplasmas and intraamniotic infection with other microorganisms.


METHODS
We examined the intensity of intraamniotic and maternal inflammatory responses in 99 patients with preterm premature rupture of membranes and a positive amniotic fluid (AF) culture. AF was obtained by transabdominal amniocentesis or at the time of cesarean delivery. Patients were divided according to the recovered microorganisms: (1) genital mycoplasmas (n = 62); (2) other microorganisms (n = 31); or (3) mixed infection (n = 6).


RESULTS
The median AF white blood cell (WBC) count, maternal blood WBC count, and plasma C-reactive protein concentrations were significantly higher in patients with intraamniotic infection with genital mycoplasmas than in those with intraamniotic infection with other microorganisms (P < .05 for each).


CONCLUSIONS
Intraamniotic and maternal inflammatory responses are more intense in intraamniotic infection with genital mycoplasmas than in intraamniotic infection with other microorganisms in patients with preterm premature rupture of membranes.
