[Leukocyte esterase in the rapid detection of intraamniotic infection]
1Division of Obstetrics and Gynecology, Soroka Medical Center, Beer Sheba.
Abstract:
Several lines of evidence support the view that premature rupture of the membranes and premature labor are associated with bacterial infection of the amniotic cavity. The standard method of diagnosing intraamniotic infection is amniotic fluid culture, but the results become available only after 72 hours. Methods for more rapid diagnosis of bacterial invasion are therefor needed. We examined leukocyte esterase activity for this purpose. Amniotic fluid obtained from 62 women in preterm labor was cultured for aerobic, anaerobic and mycoplasma species. Leukocyte esterase activity was measured with a Bio-dynamics test strip. The sensitivity of the test was 50.0% and its specificity 93.4%. It was found to be a simple and rapid method for the detection of intraamniotic infection.
Insights
Rapid detection of intraamniotic infection is crucial for preterm labor management. Leukocyte esterase activity in amniotic fluid offers a quick diagnostic method, aiding timely clinical decisions.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Clinical Diagnostics
Context:
- Premature rupture of membranes and preterm labor are linked to bacterial infection within the amniotic cavity.
- Current diagnostic methods like amniotic fluid culture require 72 hours for results, delaying treatment.
- There is a need for faster diagnostic techniques to identify bacterial invasion promptly.
Purpose:
- To evaluate the utility of leukocyte esterase activity as a rapid diagnostic marker for intraamniotic infection.
- To assess the sensitivity and specificity of leukocyte esterase testing in amniotic fluid from women in preterm labor.
Summary:
- Amniotic fluid samples from 62 women experiencing preterm labor were analyzed for bacterial cultures (aerobic, anaerobic, mycoplasma).
- Leukocyte esterase activity was measured using a Bio-dynamics test strip.
- The test demonstrated a sensitivity of 50.0% and a specificity of 93.4% for detecting intraamniotic infection.
Impact:
- Leukocyte esterase activity provides a simple, rapid method for diagnosing intraamniotic infection.
- This rapid diagnosis can potentially lead to earlier intervention and improved outcomes for preterm labor cases.
- The findings support the integration of leukocyte esterase testing into clinical practice for faster infection detection.
