Summary
Amniotic fluid lysozyme levels can indicate fetal distress. Lower levels in high-risk pregnancies suggest potential fetal well-being issues, aiding in early detection.
Area of Science:
- Biochemistry
- Obstetrics
- Neonatal Health
Background:
- Lysozyme is an enzyme with antimicrobial properties.
- Changes in amniotic fluid composition can reflect fetal health status.
- Fetal distress is a critical condition requiring timely diagnosis.
Purpose of the Study:
- To investigate the correlation between amniotic fluid lysozyme activity and fetal distress.
- To determine if lysozyme levels can serve as a biomarker for fetal distress.
Main Methods:
- Measurement of lysozyme activity in amniotic fluid samples.
- Analysis of samples from pregnant women across different gestational ages (30-41 weeks).
- Comparison of lysozyme levels between normal, pathological, and high-risk pregnancies with and without fetal distress.
Main Results:
- Amniotic fluid lysozyme levels were similar in normal and pathological pregnancies without fetal distress.
- Lysozyme levels showed a trend toward increase with advancing gestational age in uncomplicated pregnancies.
- Significantly lower lysozyme levels were observed in high-risk pregnancies with signs of fetal distress.
Conclusions:
- Amniotic fluid lysozyme activity may serve as a potential indicator of fetal distress.
- Monitoring lysozyme levels could aid in identifying fetuses at risk.
- Further research is warranted to validate lysozyme as a reliable biomarker for fetal well-being.
