Insights
Ubiquinone-10 (coenzyme Q), an antioxidant, has established reference ranges in European children. Plasma levels were found to be age-dependent, decreasing with age, but not sex-dependent.
Area of Science:
- Biochemistry
- Pediatrics
- Nutritional Science
Background:
- Ubiquinone-10 (coenzyme Q) functions as a crucial physiological antioxidant in human blood.
- Establishing pediatric reference ranges is vital for understanding its role in child health.
Purpose of the Study:
- To determine the reference range for plasma ubiquinone-10 levels in healthy European infants and children.
- To investigate potential correlations with age and sex in this pediatric population.
Main Methods:
- Plasma ubiquinone levels were measured in 50 healthy European children aged 2 months to 15 years.
- Statistical analysis was performed to assess correlations with age and sex.
Main Results:
- A mean plasma ubiquinone level of 0.75±0.27 μg/ml was determined.
- Concentrations showed a negative correlation with age (r = -0.37, P=0.0075), with higher levels in younger children.
- No significant sex-dependent differences were observed.
Conclusions:
- The study provides reference values for plasma ubiquinone-10 in European children.
- Age is a significant factor influencing ubiquinone-10 levels during childhood.
- These findings contribute to the understanding of antioxidant status in pediatric populations.
Abstract:
The reduced form of ubiquinone-10 (coenzyme Q) has been shown to represent an important physiologic antioxidant principle in human blood. In order to establish a reference range for infants, we measured plasma levels of ubiquinone in 50 healthy European children aged 2 months to 15 years. A mean ±SD) value of 0.75±0.27 μg/ml plasma (0.87±0.31 μM) was determined; ubiquinone concentrations were not found to be sex-dependent (0.7±0.24μg/ml for girls, n=17, and 0.7±0.28μg/ml for boys, n=33) but correlated negatively with age (r = -0.37, P=0.0075). This negative correlation was mainly due to relatively high levels in infants approximately 1 year old. The mean value determined does not significantly differ from the average ubiquinone plasma concentrations determined in healthy Nigerian children (0.85±0.40 μg/ml, n= 18) in a previous study (Becker K, Boetticher D, Leichsenring M. Internat J Vitam Nutr Res 1995, in press).
