    Abstract:
    The present study aimed to investigate whether microbial invasion of the amniotic cavity affects maternal plasma or placental immunoreactive corticotrophin releasing factor (ir-CRF) concentrations in pregnant women with pre-term or term labour. A cross-sectional study was conducted collecting blood samples in: (1) women with pre-term labour and intact membranes (25-36 weeks), with or without microbial invasion of the amniotic cavity (subdivided into three groups: 1A, no microbial invasion of the amniotic cavity, delivery at term, n = 54; group 1B, delivery < 48 h, no microbial invasion of the amniotic cavity, n = 10; group 1C, delivery < 48 h, microbial invasion of the amniotic cavity, n = 8); (2) women at term, not in labour and without microbial invasion of the amniotic cavity (n = 15); (3) women in spontaneous active labour at term without (A) (n = 55) or with (B) (n = 16) microbial invasion of the amniotic cavity; and (4) healthy women not in labour at 25-36 weeks of gestation (n = 25). Specimens of trophoblast tissue were collected from pregnant women with pre-term labour (no microbial invasion of the amniotic cavity, n = 6; microbial invasion of the amniotic cavity, n = 4) or delivering at term (no microbial invasion of the amniotic cavity, n = 8; microbial invasion of the amniotic cavity, n = 4). A specific radioimmunoassay on acidic extracts of plasma or placental specimens was used.(ABSTRACT TRUNCATED AT 250 WORDS)
