Low-grade inflammation links obesity, insulin resistance, and cardiovascular diseases. We investigated the effects of laparoscopic sleeve gastrectomy (LSG) on expression profile of genes involved in inflammatory pathways in subcutaneous adipose tissue (SCAT) and peripheral monocytes (PM).

At baseline, obese group had significantly increased mRNA expression of proinflammatory chemokines (CCL-3, -17, -22), chemokine receptor CCR1 and cytokines (IL-10, IL-18) in SCAT and chemokine and other proinflammatory receptors (CCR-1, -2, -3, TLR-2, -4) in PM relative to control group. LSG decreased body weight, improved metabolic profile and reduced mRNA expression of up-regulated chemokine receptors, chemokines and cytokines in SCAT.

In contrast, expression profiles in PM were largely unaffected by LSG. We conclude that LSG improved proinflammatory profile in subcutaneous fat but not in peripheral monocytes.

The sustained proinflammatory and chemotactic profile in PM even 2 years after LSG may contribute to partial persistence of metabolic complications in obese patients after metabolic surgery.
