Variation of chest radiographic patterns in pulmonary tuberculosis by degree of human immunodeficiency virus-related immunosuppression. The Terry Beirn Community Programs for Clinical Research on AIDS (CPCRA). The AIDS Clinical Trials Group (ACTG).
Our aim was to evaluate the effect of human immunodeficiency virus (HIV) disease stage on chest radiographic (CXR) findings among patients with HIV-related pulmonary tuberculosis (TB). Data are from a prospective multicenter treatment trial for HIV-related TB. Baseline CXR findings and CD4+ lymphocyte counts were compared among patients with HIV-related TB. Data from published studies describing CXR findings in HIV-infected patients were reviewed and a pooled-data analysis was conducted. Of 135 patients with culture-confirmed HIV-related TB, 128 had both CXR and CD4+ lymphocyte data. CD4+ lymphocyte counts of < 200/mm3 (n = 98) were significantly associated with hilar/mediastinal adenopathy on CXR (30%, vs. 7% with counts > or = 200/mm3; P = .01); counts of > or = 200/mm3 (n = 30) more frequently were associated with cavitation (20% vs. 7%; P = .08). Analyses of these results, pooled with other published data, confirmed these findings. This study demonstrates associations of certain CXR findings with HIV disease stage. Knowledge of the degree of immunosuppression is important when evaluating CXR findings in HIV-infected patients.
