IL10 and serum lipopolysaccharide activity: The endotoxemia-induced increase in anti-inflammatory cytokine IL-10 was attenuated in subjects treated with atazanavir: 219 (95%CI: 152-318) pg/mL versus 377 (95%CI: 233-609) pg/mL in subjects in the placebo group (over time, both p<0.001, between groups p=0.01).
