Pulmonary tuberculosis in HIV infection: Radiographic appearance is related to CD4+ T-lymphocyte count

摘要: Abstract Setting: An adult HIV outpatient clinic in Cape Town, South Africa. Objective: To investigate the relationship between radiographic appearance of pulmonary tuberculosis (PTB) infected patients and CD4 + T-lymphocyte count. Design: Pretreatment radiographs 150 with newly diagnosed PTB were reviewed. Tlymphocyte count was used as a marker disease progression. Results: Upper zone infiltrate typical reactivation present 18 patients. This pattern associated early infection (mean T-cell 389) had 78% positive predictive value for identifying > 200 T-lymphocytes/μL. Pleural effusion 32 occurred over wide intermediate range counts 185). Lower or midzone infiltrates, adenopathy, interstitial normal radiograph 136 advanced 105). These patterns 84%, 89%, 89% 100% value, respectively, T-cells/μL. Conclusion: Pulmonary African HIV-positive presents spectrum abnormalities, specific are stage In dually PTB, chest useful adjunct to clinical staging.
