Serum Fatty Acids and Inflammatory Patterns in Severe Obesity: A Preliminary Investigation in Women

Abstract

Background: Inflammation plays a central role in many chronic diseases that characterize modern society. Leptin/adiponectin and adiponectin/leptin ratios have been recognized as notable markers of dysfunctional adipose tissue and, consequently, an inflammatory state. Methods: Blood samples were collected from 41 adult volunteers (40.2 ± 8.3 years) diagnosed with severe obesity (BMI 46.99; 42.98–51.91 kg/m2). The adipokines were quantified using an enzyme-linked immunosorbent assay, while the serum fatty acid analysis was conducted using chromatography. Results: The results unveiled a positive correlation between the leptin/adiponectin ratio and the 20:3n6 fatty acid (r = 0.52, p = 0.001), as well as a similar positive correlation between the adiponectin/leptin ratio and the 22:6n3 fatty acid (r = 0.74, p = 0.001). In the regression analysis, the 22:6n3 fatty acid predicted the adiponectin/leptin ratio (β = 0.76, p p Conclusions: In conclusion, the 22:6n3 fatty acid was demonstrated to be a predictive factor for the adiponectin/leptin ratio and C20:3 n-6 was a predictor for inflammatory markers. This discovery, novel within this population, can help develop new intervention strategies aimed at controlling the inflammatory status in individuals classified as having severe obesity.
