Intra-amniotic Infection |
| Purpose: |
|
The purpose of this study is to collect clinical specimens and corresponding clinical data
to develop a non-invasive test for detection of intra-amniotic infection and prediction of
preterm birth in women and intact amniotic membranes. The specimens collected will be used
to develop a specific biomarker panel and algorithm using immunoassays for optimal detection
of intra-amniotic infection in women with preterm labor and intact amniotic membranes.

| Study Summary: |
|
Intra-amniotic infection (IAI) is an acute bacterial infection of the amniotic fluid and
intrauterine contents during pregnancy and occurs in 4% to 10% of all deliveries (Newton,
ER., 1993. Newton, ER, et al., 1989. Soper, DE, et al., 1989). IAI is an important cause
of maternal and neonatal morbidity. Identifying and appropriately treating women with IAI
is, therefore, a major obstetrical challenge.
Intrauterine infection may occur early in pregnancy and remain undetected for a prolonged
period, thus exposing the fetus to the effects of infection/inflammation for a considerable
period. Ideally, an early diagnosis of IAI is important to allow timely treatment and
intervention. Unfortunately, the early diagnosis is difficult because the clinical signs
and symptoms of IAI may occur late in the course of the infection and are neither sensitive
nor specific. Therefore, to avoid a delay in diagnosis a high degree of suspicion and the
appropriate use of adjunctive laboratory tests are warranted.
