Insights
Osteopontin (OPN) levels are highest in newborns and decline with age throughout childhood. This study establishes the first reference values for OPN in children, crucial for understanding its role in pediatric health.
Area of Science:
- Biochemistry
- Pediatrics
- Biomarker Research
Background:
- Osteopontin (OPN) is a known biomarker for various diseases.
- Limited data exists on OPN's role and reference values in pediatric populations.
Purpose of the Study:
- Establish OPN reference values in children from birth to young adulthood.
- Investigate age, gender, and weight-specific differences in pediatric OPN levels.
Main Methods:
- Collected umbilical cord blood and blood plasma from 117 children.
- Measured OPN levels using ELISA.
- Performed statistical analysis to identify age-related trends.
Main Results:
- Highest OPN blood levels were observed in neonates and infants (0-1 year olds).
- OPN levels showed a significant age-related decline (Spearman r = -0.874, P < 0.001).
- OPN levels in adolescents approached adult values by age 14.
Conclusions:
- This is the first prospective study to provide systematic OPN reference values for children across all age groups.
- Physiological influences on OPN during childhood development are elucidated.
- The findings highlight a significant age-related decrease in OPN from birth to young adulthood.
Aim:
Osteopontin (OPN) has been investigated as a biomarker for cancer and nonmalignant diseases during the last decades. Data about OPN as a potential biomarker in childhood diseases are still sparse, and reference values are not available in children. We aimed to establish reference values for children from birth to young adulthood and evaluate whether there are age-, gender-, and weight-specific differences.
Method:
Umbilical cord blood and blood plasma samples of 117 children were collected in the Children's Hospital of Saarland University in Homburg/Saar. OPN levels were measured by ELISA, and statistical analysis was performed using SPSS software.
Results:
Neonates, infants, toddlers, young children, adolescents, and adults were divided into the following six age groups: newborns (birth), infancy and toddlers (0-24 months), early childhood (3-6 years), middle childhood (7-11 years), adolescence (12-18 years), and adults (> 18 years). Highest blood OPN levels were found in the group of 0-1 years of age. OPN blood levels declined significantly with age (Spearman r = -0.874; P < 0.001).
Conclusion:
Our work is the first prospective and systematic study analyzing OPN cord blood and blood plasma levels in children of all ages. It is the first study yielding reference values for different age groups from birth to young adulthood. Our data give insight on how OPN in umbilical cord blood and OPN in blood plasma are physiologically influenced during childhood development and growth with high OPN levels after birth and a constant age-related decline until the age of 14, when OPN levels reach similar values to those measured in adults.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
