Summary
Midtrimester amniotic fluid tumor necrosis factor-alpha (TNF-alpha) levels do not predict small-for-gestational-age (SGA) infants. This study found no significant difference in TNF-alpha levels between mothers delivering SGA neonates and controls.
Area of Science:
- Reproductive Medicine
- Immunology
- Neonatal Health
Background:
- Small-for-gestational-age (SGA) infants are at increased risk for adverse outcomes.
- Biomarkers for predicting SGA are crucial for timely intervention.
- Tumor necrosis factor-alpha (TNF-alpha) is an inflammatory cytokine implicated in various pregnancy complications.
Purpose of the Study:
- To determine if midtrimester amniotic fluid TNF-alpha levels can independently predict the delivery of SGA neonates.
- To assess the diagnostic utility of amniotic fluid TNF-alpha in SGA prediction.
Main Methods:
- A case-control study design was employed, matching SGA neonate cases with controls.
- Amniotic fluid samples were collected and analyzed for TNF-alpha levels using immunoassays.
- Exclusion criteria included maternal immune diseases, chronic hypertension, diabetes, asthma, congenital heart disease, multiple gestations, and fetal anomalies.
Main Results:
- No significant differences in confounding variables were observed between the SGA and control groups.
- Amniotic fluid TNF-alpha levels did not differ significantly between patients who delivered SGA neonates and controls.
- The median TNF-alpha levels were 7.63 pg/mL for SGA cases and 9.39 pg/mL for controls (P = 0.8).
Conclusions:
- Midtrimester amniotic fluid TNF-alpha levels are not a reliable predictor of SGA neonates.
- Further research may be needed to identify alternative biomarkers for SGA prediction.
