Abstract

Inflammation, oxidative stress and dysregulation of adipokines are thought to be pathophysiological mechanisms linking obesity to the development of insulin resistance and atherosclerosis. In adults, bariatric surgery reduces inflammation and oxidative stress, and beneficially changes the levels of several adipokines, but little is known about the postsurgical changes among adolescents. In two separate longitudinal cohorts we evaluated change from baseline of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), monocyte chemo-attractant protein-1 (MCP-1), oxidized low-density lipoprotein cholesterol (oxLDL), adiponectin, leptin and resistin up to 12 months following elective laparoscopic Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG) surgery in adolescents with severe obesity. In cohort 1, which consisted of 39 adolescents (mean age 16.5±1.6 years; 29 females) undergoing either RYGB or VSG, IL-6 (baseline: 2.3±3.4 pg ml(-1) vs 12 months: 0.8±0.6 pg ml(-1), P<0.01), leptin (baseline: 178±224 ng ml(-1) vs 12 months: 41.4±31.9 ng ml(-1), P<0.001) and oxLDL (baseline: 41.6±11.6 U l(-1) vs 12 months: 35.5±11.1 U l(-1), P=0.001) significantly decreased and adiponectin significantly increased (baseline: 5.4...Continue Reading
