Abstract

The well treated HIV population remains at risk for insulin resistance and chronic immune activation. We tested the effects of acute hyperinsulinemia on inflammation in HIV. Twenty HIV-infected and 10 non-HIV-infected individuals well matched for BMI underwent oral glucose tolerance testing to stimulate insulin secretion and assess for changes in circulating soluble CD163, soluble CD14, and monocyte chemoattract protein 1. Soluble CD14 decreased significantly after stimulation of hyperinsulinemia and no significant changes in soluble CD163 or monocyte chemoattract protein 1 were demonstrated in HIV-infected and non-HIV-infected groups.
