MENDOZA DE S, Maryalejandra et al. CT pulmonary findings and their association with CD4+ T lymphocytes levels in human immunodeficiency virus carriers. Rev. chil. radiol. [online]. 2011, vol.17, n.2, pp. 61-66. ISSN 0717-9308. doi: 10.4067/S0717-93082011000200003.
Respiratory diseases are frequent complications in HIV infection. High Resolution Computed Tomography (HRCT) has proven superior to conventional imaging techniques to establish a pulmonary disease diagnosis. A study was conducted in order to establish the association between tomographic pulmonary patterns and immune status of HIV-infected patients. We evaluated 35 patients with respiratory symptoms and / or abnormal chest radiograph. An association was observed between the presence of ground glass pattern and P jirovecii infection. Likewise, a correlation between pulmonary histoplasmosis diagnosis and honeycomb pattern, lung cysts and nodules was established. Few correlation between tomographic patterns and CD4 + T lymphocyte counts was observed. In summary, HRCT findings can predict certain types of infection; nevertheless, further studies are required to extrapolate this association to other noninfectious lung diseases in HIV-infected patients.
