Lower FEV₁ post-TB treatment completion is correlated with greater increases in immune function from baseline to week 4 post-ART initiation in HIV-infected patients with a history of active pTB. Forced expiratory volume in one-second (FEV₁) was measured by pulmonary function testing post-TB treatment completion in HIV-infected patients to determine percent predicted of normal. Shown are Spearman's correlation coefficients (rho: r) and corresponding p values comparing percent predicted FEV₁ to change from baseline to week 4 post-ART in (a) CD4 count (n = 14) and (b) frequency of IFN-γ and (c) TNF-α producing CD4⁺ T-cells (n = 10) upon PPD stimulation.
