Background: Excessive visceral fat with unbalanced adipokines is a critical pathogenic factor of metabolic syndrome (MetS), which is associated with disorders of the central nervous system and cardiovascular disease. Because brain-derived neurotrophic factor (BDNF) plays an important role in neurons, we examined the relationship of BDNF to MetS, adipose tissue and biomarkers in men. Methods: Thirty-four non-diabetic men with MetS and another 24 age-matched men without MetS were enrolled. In addition to fasting blood samples, the area of adipose tissue at the waist was assessed by magnetic resonance imaging (MRI). Results: There was no significant difference in serum BDNF concentrations between men with or without MetS (40.9 +/- 8.0 vs. 432 +/- 6.1 ng/ml, P = 0235). However, the serum concentration of soluble vascular cell adhesion molecule-1 (VCAM-1) was higher in the subjects with a lower BDNF level (737 +/- 230 vs. 628 +/- 115 ng/ml, P=0.025). An inverse correlation between VCAM-1 and BDNF was observed (r = -0.391, P = 0.002). After adjusting for visceral adipose tissue, VCAM-1 was found to be independently associated with BDNF[95% confidence interval (-0.025, -0.005), P = 0.004]. Conclusion: These data show no difference in serum BDNF levels between the men with MetS and controls. However, serum BDNF was inversely correlated with serum VCAM-1 in men without diabetes.
