Summary

This study establishes 0.3 mg/ml as the cutoff for normal fetal coenzyme Q10 (CoQ10) plasma levels. Elevated CoQ10 was observed in fetuses with hypoxic hypoxia and nonimmune hydrops.

Area of Science:

  • Biochemistry
  • Perinatology
  • Neonatal Research

Background:

  • Coenzyme Q10 (CoQ10) is vital for cellular energy production.
  • Fetal CoQ10 levels and their clinical significance are not well-established.
  • Understanding CoQ10 variations can aid in diagnosing fetal distress.

Purpose of the Study:

  • To determine a cutoff value distinguishing fetal from adult CoQ10 plasma levels.
  • To compare CoQ10 plasma level increases in fetuses with specific conditions.
  • To investigate CoQ10 as a potential biomarker in high-risk pregnancies.

Main Methods:

  • Analysis of CoQ10 levels in fetal and maternal blood samples from 61 pregnancies.
  • Cordocentesis was used for sample collection.
  • Inclusion of control groups and pregnancies with intrauterine growth retardation, Rh isoimmunization, nonimmune fetal hydrops, and fetal malformations.

Main Results:

  • A cutoff value of 0.3 mg/ml was established to differentiate fetal from adult CoQ10 levels.
  • Significantly higher CoQ10 plasma levels were found exclusively in fetuses with hypoxic hypoxia and nonimmune hydrops.
  • No significant CoQ10 elevation was noted in fetuses with intrauterine growth retardation or Rh isoimmunization.

Conclusions:

  • Normal fetal CoQ10 plasma levels are below 0.3 mg/ml.
  • Elevated fetal CoQ10 may serve as an indicator for hypoxic hypoxia and nonimmune hydrops.
  • Further research is warranted to explore the diagnostic utility of CoQ10 in fetal medicine.
