STYJOBS / EDECTA - ResultsSummary

HMW adiponectin is decreased in the early phase of vascular abnormalities in obesity.

As the LMW subfraction is increased, and the HMW subfraction decreased, the oligomerisation from LMW to HMW adiponectin may be disturbed.

Trunk weighted obesity is associated with very low HMW adiponectin, and stronger increased carotis IMT.

HDL cholesterol decrease is the best predictor for lipid peroxidation.

Mangge et al Atherosclerosis 2009, PMID: 18656877 Mangge et al Obesity Research 2008, PMID: 18846045

General conclusion

Obesity is a chronic inflammatory disease.

Irrespective of sex, age and gender, the inflammatory activation associated with abdominal fat accumulation is crucial for obesity related sequels like atherosclerosis.

Adipokines are centrally involved in the chronic inflammation of obesity. The balancebetween the most abundant adipokines , adiponectin and leptin may be crucial for the clinical course of atherosclerosis.

The “obesity paradox” may be explained by “protective” antiinflammatory qualities of the adipose tissue. However, abdominal (trunk) obesity abrogates the protective effects.

Therapeutic modification of chronic low grade inflammation with reference to the individual SAT distribution may become an important challenge for the future.

STYJOBS / ResultsConclusion

Our data show that already the early phase of obesity is associated with chronic

inflammation, preatherosclerosis, and an essentially altered adipokine synthesis.

SAT- distribution (visceral, nuchal) is a crucial risk factor.
