Salivary Biomarkers in Pediatric Metabolic Disease Research
Insights
Childhood obesity is a global pandemic. Saliva analysis offers a non-invasive method for early detection of metabolic risks and immunometabolism biomarkers in children, aiding early intervention.
Area of Science:
- Pediatric Endocrinology
- Metabolic Research
- Immunometabolism
Background:
- Childhood obesity and related metabolic disorders represent a significant global health challenge.
- Early identification of at-risk children is crucial for preventing severe obesity and metabolic complications.
- Current screening methods often face challenges with parental and child acceptance due to invasiveness.
Purpose of the Study:
- To review the potential of salivary analysis for biomarker discovery in pediatric metabolic health.
- To evaluate saliva as a non-invasive fluid for screening, diagnosis, and monitoring of metabolic disorders in children.
- To highlight advancements and future directions in salivary diagnostics for pediatric obesity.
Main Methods:
- Review of physiological roles of saliva in biomarker discovery.
- Analysis of current literature on salivary biomarkers for metabolic health in children and adolescents.
- Discussion of technological advancements in salivary 'omics' and point-of-care diagnostics.
Main Results:
- Saliva presents a promising, non-invasive alternative to blood sampling for biomarker analysis.
- Salivary analysis can aid in identifying metabolic health and immunometabolism biomarkers in at-risk children.
- The field is advancing with 'omics' technologies and point-of-care devices for improved diagnostics.
Conclusions:
- Saliva is a viable and acceptable biofluid for large-scale screening and diagnosis of pediatric obesity and related metabolic disorders.
- Further research and technological development in salivary diagnostics are essential for effective early intervention strategies.
- Salivary analysis holds significant potential for monitoring treatment response and advancing pediatric metabolic health research.
Abstract:
The increasing prevalence of childhood obesity and obesity-related metabolic disorders is now considered a global pandemic. The main goal of the pediatric obesity research community is to identify children who are at risk of becoming obese before their body mass index rises above age norms. To do so, we must identify biomarkers of metabolic health and immunometabolism that can be used for large-scale screening and diagnosis initiatives among at-risk children. Because blood sampling is often unacceptable to both parents and children when there is no direct benefit to the child, as in a community-based research study, there is a clear need for a low-risk, non-invasive sampling strategy. Salivary analysis is now well recognized as a likely candidate for this purpose. In this review, we discuss the physiologic role of saliva and its strengths and limitations as a fluid for biomarker discovery, obesity screening, metabolic disease diagnosis, and response monitoring after interventions. We also describe the current state of the salivary biomarker field as it pertains to metabolic research, with a special emphasis on studies conducted in children and adolescents. Finally, we look forward to technological developments, such as salivary "omics" and point of service diagnostic devices, which have the potential to accelerate the pace of research and discovery in this vitally important field.
