Maternal plasma fetuin-A levels in fetal growth restriction: A case-control study

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine
• Biochemistry

Background:

• Fetuin-A (FA) is linked to obesity and has emerging relevance in pregnancy outcomes.
• Understanding maternal FA's role in fetal development is crucial.

Purpose of the Study:

• To investigate the association between maternal plasma Fetuin-A (FA) levels and fetal growth restriction (FGR).

Main Methods:

• A case-control study involving 41 pregnant women with FGR and 40 controls.
• Maternal venous blood samples were collected for FA analysis upon FGR diagnosis.

Main Results:

• Significantly elevated maternal plasma FA levels were observed in the FGR group compared to controls (25.9 ± 6.8 ng/ml vs 19.3 ± 3.0 ng/ml, p=0.001).
• Receiver operating characteristic (ROC) curve analysis indicated an area under the curve of 0.815 for FA in predicting FGR.
• FA levels >22.5 ng/ml demonstrated a sensitivity of 73.17% and specificity of 82.5% for FGR detection, with an overall diagnostic accuracy of 77.78%.

Conclusions:

• This study demonstrates higher maternal plasma FA levels in pregnancies affected by FGR.
• Further research is warranted to elucidate the long-term impacts of FA in FGR pregnancies and its potential for early FGR prediction.
