Circulating LPS levels in dual HIV/tuberculosis-infected subjects with low CD4 T-cell count (<350/μL) at diagnosis of tuberculosis. LPS and LBP were assessed in plasma from HIV/tuberculosis subjects at time of diagnosis of tuberculosis. (A) LPS levels at time of diagnosis of HIV/tuberculosis and in CD4-matched healthy HIV-infected subjects are shown. (B) LBP levels in the same samples as in panel A are shown. Abbreviations: HIV, human immunodeficiency virus; LBP,LPS binding protein; LPS, lipopolysaccharide.
