Abstract OBJECTIVE: To analyze the effects of the surgical removal of subcutaneous adipose tissue by ultrasound-assisted megalipoplasty (UAM) on energy expenditure and adipocytokine concentrations in obese women. METHODS: Fifteen premenopausal obese women with BMI 37.5+/-6.3 kg/m(2) (range: 30.7-53.6 kg/m(2)) underwent UAM. Body composition (by DEXA), resting metabolic rate (REE) by indirect calorimetry, insulin resistance (by the HOMA method), leptin, C-reactive protein, interleukin-6, resistin and adiponectin were measured before and 1, 3, 28 and 180 days after the procedure. RESULTS: UAM significantly reduced fat mass at day 3, without further changes in the following days. REE increased at day 3 after UAM, returned to baseline levels at day 28 and significantly declined at day 180. Leptin levels transiently increased after UAM and then declined according to fat mass reduction. C-reactive protein, interleukin-6 and resistin levels acutely increased after UAM and then returned to the baseline levels. Adiponectin levels acutely declined after the procedure and then stabilized to a plasma level slightly lower than at baseline. Insulin resistance deteriorated in the acute post-operative phase and then improved. CONCLUSION: The surgical removal of subcutaneous fat was associated to an acute inflammatory reaction with high REE and insulin-resistance. Later on, the metabolic effects of fat mass removal appeared, with a reduction of leptin levels and REE and an improvement of insulin resistance.

Abstract OBJECTIVE: To analyze the effects of the surgical removal of subcutaneous adipose tissue by ultrasound-assisted megalipoplasty (UAM) on energy expenditure and adipocytokine concentrations in obese women. METHODS: Fifteen premenopausal obese women with BMI 37.5+/-6.3 kg/m(2) (range: 30.7-53.6 kg/m(2)) underwent UAM. Body composition (by DEXA), resting metabolic rate (REE) by indirect calorimetry, insulin resistance (by the HOMA method), leptin, C-reactive protein, interleukin-6, resistin and adiponectin were measured before and 1, 3, 28 and 180 days after the procedure. RESULTS: UAM significantly reduced fat mass at day 3, without further changes in the following days. REE increased at day 3 after UAM, returned to baseline levels at day 28 and significantly declined at day 180. Leptin levels transiently increased after UAM and then declined according to fat mass reduction. C-reactive protein, interleukin-6 and resistin levels acutely increased after UAM and then returned to the baseline levels. Adiponectin levels acutely declined after the procedure and then stabilized to a plasma level slightly lower than at baseline. Insulin resistance deteriorated in the acute post-operative phase and then improved. CONCLUSION: The surgical removal of subcutaneous fat was associated to an acute inflammatory reaction with high REE and insulin-resistance. Later on, the metabolic effects of fat mass removal appeared, with a reduction of leptin levels and REE and an improvement of insulin resistance.
