Figure 6From: Virologic and immunologic outcome of HAART in Human Immunodeficiency Virus (HIV)-1 infected patients with and without tuberculosis (TB) and latent TB infection (LTBI) in Addis Ababa, EthiopiaSpearman correlation between IFN-γ production and absolute CD4+ count recovery after the start of HAART and TB treatment. (A) HIV positive patients with active TB (HIV + TB+) at 6th and 18th months of HAART and TB treatment, and (B) HIV negative TB patients (HIV-TB+) at six months of TB treatment. IFN-γ secretion was measured in 7th day culture supernatants of whole blood stimulated with Mtb specific antigen (ESAT-6/CFP-10). r = correlation coefficient.Back to article page
