Granulocyte Colony-Stimulating Factor in Amniotic Fluid
Author Information
Author(s): B. Denise Raynor, Penny Clark, Patrick Duff
Primary Institution: University of Florida
Hypothesis
Is granulocyte colony-stimulating factor (G-CSF) normally present in amniotic fluid and are its levels affected by labor and intrauterine infection?
Conclusion
G-CSF is present in amniotic fluid and increases with labor, significantly elevated in the presence of chorioamnionitis.
Supporting Evidence
- G-CSF levels were significantly lower prior to labor compared to during labor.
- Mean G-CSF levels in chorioamnionitis were significantly elevated compared to normal labor.
- Patients with chorioamnionitis had a longer interval with ruptured membranes.
Takeaway
This study found that a substance called G-CSF is in the fluid around babies before they are born, and its amount goes up when mothers are in labor or have an infection.
Methodology
Amniotic fluid was collected from 35 patients in four groups, and G-CSF levels were measured using ELISA.
Potential Biases
The sample may not represent normal labor as most laboring patients received oxytocin.
Limitations
The study had a small sample size and included patients with some pregnancy complications.
Participant Demographics
Patients included those not in labor, in early labor, in late labor, and in labor with chorioamnionitis.
