BACKGROUND: Fatty acids (FAs) play pivotal roles in modulating inflammatory pathways in celiac disease (CD). The present study explored the relationship between serum FAs levels and the expression of both pro- and anti-inflammatory cytokines in adult and pediatric patients with CD.
METHODS: Serum FA levels in 20 treated CD patients (11 children, 9 adults) and 20 healthy controls (10 children, 10 adults) were analyzed using gas chromatography. Cytokine gene expression (IL-6, TNF-α, IL-10, IL-12, TGFβ, NF-κB) was assessed through quantitative real-time PCR.
RESULTS: Myristoleic acid levels decreased in children with CD (p = 0.03) but increased in adults (p = 0.04). Elevated IL-6 mRNA expression was found in both pediatric (p = 0.01) and adult (p = 0.04) groups. TNF-α expression was significantly higher in adults (p = 0.01). In children, IL-10 mRNA levels positively correlated with palmitic acid (p = 0.01, r = 0.73), and TGF-β correlated with myristoleic acid (p = 0.03, r = 0.63). In adults, IL-10 positively correlated with dihomo-gamma-linolenic acid (p = 0.04, r = 0.68) and negatively with linoleic acid (p = 0.02, r = -0.72). These age-related differences may reflect variations in disease duration, metabolic and developmental factors, dietary intake, and gut microbiota composition.
CONCLUSION: These findings suggest that FAs could be therapeutic targets for improving CD management across different age groups.
