Resumo

The purpose of this study was to assess the level of cytokine expression in correlation with visceral and subcutaneous fat in obese adolescents admitted to long-term interdisciplinary weight loss therapy. The study was a longitudinal clinical intervention of interdisciplinary therapy. Adolescents (18, aged 15-19 years) with body mass indexes greater than the 95th percentile were admitted and evaluated at baseline and again after 1 year of interdisciplinary therapy. Visceral and subcutaneous fat was analyzed by ultrasonography. Blood samples were collected to analyze tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), interleukin-10 (IL-10), and adiponectin concentrations that were measured by enzyme-linked immunosorbent assay. The most important finding in the present investigation is that the long-term interdisciplinary lifestyle therapy decreased visceral fat. Positive correlations between IL-6 levels and visceral fat (r = 0.42, P < .02) and TNF-alpha levels and visceral fat (r = 0.40, P < .05) were observed. Negative correlations between TNF-alpha levels and subcutaneous fat (r = -0.46, P < .01) and adiponectin levels and subcutaneous fat (r = -0.43, P < .03) were also observed. In addition, we found a positive correlation between TNF-alpha levels and the visceral to subcutaneous fat ratio (r = 0.42, P < .02) and a negative correlation between adiponectin level and the visceral to subcutaneous fat ratio (r = -0.69, P < .001). Despite the limitation of sample size, our results indicate that the observed massive weight loss (mainly visceral fat) was highly correlated with a decreased inflammatory state, suggesting that the interdisciplinary therapy was effective in decreasing inflammatory markers.
