Aim: Obesity is a multifactorial disease, associated with metabolic disorders and chronic low-grade inflammation. Circulating
procalcitonin (PCT) is produced by adipose tissue and several cell types following cytokine stimulation. Procalcitonin is well
known as a biomarker of infection, sepsis and severe systemic inflammation. Recently it has a potential as a marker for chronic
low-grade inflammation in obese population. We aim in the current study to evaluate the role of serum PCT as an inflammatory
biomarker in diagnosis of obesity-related low-grade inflammation.
Method: In this case control study, 50 obese and 50 normal weight children and adolescents aged 6â??16 years were enrolled.
Anthropometric parameters and blood pressure were measured in all study subjects. The body composition was evaluated by
body mass index (BMI), body circumferences and skinfold thickness fasting blood samples were collected for measurement
of lipid profile, blood glucose, insulin, high sensitivity-CRP (Hs-CRP) and serum procalcitonin. Serum (PCT) levels were
assessed using enzyme linked immunosorbent assay. Insulin resistance was represented as the homeostatic model assessment
value (HOMA-IR).
Results: Obese participants had increased (BMI) z-score, blood pressure, insulin resistance (HOMA-IR) and higher
concentrations of serum PCT, total cholesterol, triglycerides, glucose and Hs-CRP than control group. On correlation analysis,
procalcitonin had significant positive correlation with (BMI) z-score (P=0.03), waist circumference (WC) (P=0.05), Hs-CRP
(P=0.02)), total cholesterol (P=0.04), triglycerides (P<0.001) and (HOMA-IR) (P<0.001) in obese group.
Conclusion: The increased serum procalcitonin concentrations were closely related to measures of adiposity, Hs-CRP and
insulin resistance, suggesting that PCT may be an excellent biomarker for obesity related chronic low-grade inflammation in
children and adolescents.
