Potential biochemical markers for preterm labor: a pilot study in north India

Area of Science:

• Biochemistry
• Obstetrics
• Neonatal Health

Background:

• Preterm delivery is a leading cause of neonatal mortality.
• Reliable biomarkers are needed to assess preterm labor risk.
• Current diagnostic methods require improvement for early risk identification.

Purpose of the Study:

• To evaluate biochemical parameters as potential biomarkers for preterm labor risk assessment.
• To compare the efficacy of various biomarkers in predicting preterm delivery.
• To establish the most effective biomarker for early detection of preterm labor.

Main Methods:

• A case-control study involving 40 women in preterm labor and 40 controls delivering at term.
• Measurement of serum levels of corticotrophin (ACTH), prolactin, thyroid stimulating hormone (TSH), ferritin, and alkaline phosphatase (ALP).
• Statistical analysis including sensitivity, specificity, and predictive values for each biomarker.

Main Results:

• Serum ACTH, ferritin, ALP, and the Ferritin/Iron ratio were significantly higher in women with preterm labor.
• Ferritin demonstrated the highest predictive value with an area under the curve (AUC) of 0.96.
• ACTH (AUC 0.88), ALP (AUC 0.825), and Ferritin/Iron ratio (AUC 0.735) showed lower predictive capabilities.

Conclusions:

• Ferritin is a superior and reliable biomarker for predicting the risk of preterm labor.
• Elevated serum ferritin levels can aid in the early assessment of preterm delivery risk.
• This finding can contribute to improved management and outcomes for preterm births.
