title: The noninfectious respiratory complications of infection with HIV.
abstract: Infection with HIV was first recognized through a clustering of unusual respiratory infections. The lung has been a major target manifesting many of the infectious complications of the immunodeficiency. Noninfectious pulmonary complications in HIV-infected individuals are also common and have been recognized since the advent of the AIDS epidemic. Malignancies involving the respiratory system, specifically Kaposi's sarcoma and non-Hodgkin's lymphoma, are epidemiologically linked to infection with HIV. Although other cancers have been identified in patients with HIV, these malignancies have a relationship to HIV infection that is unknown. Nonetheless, all cancers in the HIV-infected individual appear to follow a very deadly course. Interstitial pneumonitis and an alveolitis are also seen in individuals infected with HIV. Their relationship to the virus is unknown but may involve the lung's immune response to HIV. Pneumothorax and bullous lung disease are the sequela of pulmonary infections in the HIV-infected host. Pulmonary hypertension has been reported in HIV-infected patients, and like the other noninfectious respiratory complications, the link between the disease process and HIV is unknown. Bronchiectasis is now commonly recognized in AIDS patients who have survived prolonged immunosuppression and infection. Bronchoscopists have accumulated a collection of endobronchial lesions uncommonly seen in non-HIV-related pulmonary consultation. In the following review, we discuss the epidemiology, pathology, pathogenesis, clinical features, diagnostic findings, prognosis, and therapeutic options available for each noninfectious pulmonary complication. As the life expectancy for HIV-infected patients increases, the incidence of noninfectious pulmonary complications will rise.
