We measured acute cytokine (TNF-\u03b1, IL-6, leptin), glycerol, and lactate secretion from abdominal subcutaneous adipose tissue (SAT), and systemic cytokine levels, in HIV-infected subjects with and without lipodystrophy (HIVL+ and HIVL\u2013, respectively) and healthy non-HIV controls. Lipodystrophy was confirmed and characterized as adipose tissue redistribution in HIVL+ compared with HIVL\u2013 and controls, by dual-energy X-ray absorptiometry and by whole body MRI. TNF-\u03b1 secretion from abdominal SAT and circulating levels of IL-6, soluble TNF receptors I and II, and insulin were elevated in HIVL+ relative to HIVL\u2013 and\/or controls, particularly in HIVL+ undergoing HAART. In the HIV-infected group as a whole, IL-6 secretion from abdominal SAT and serum IL-6 were positively associated with visceral fat and were negatively associated with the relative amount of lower limb adipose tissue ( P &lt; 0.01). Decreased leptin and increased lactate secretion from abdominal SAT were specifically associated with HAART. In conclusion, increased cytokine secretion from adipose tissue and increased systemic proinflammatory cytokine activity may play a significant role in the adipose tissue remodeling and\/or the metabolic abnormalities associated with the HIV-lipodystrophy syndrome in patients undergoing HAART.<\/jats:p>","DOI":"10.1152\/ajpendo.00056.2003","type":"journal-article","created":{"date-parts":[[2004,1,31]],"date-time":"2004-01-31T01:09:03Z","timestamp":1075511343000},"page":"E261-E271","source":"Crossref","is-referenced-by-count":112,"title":["Increased
