Patients infected with the human immunodeficiency virus are predisposed to develop a variety of common and uncommon infectious and neoplastic pulmonary diseases. Clinical information that can stratify the risk of occurrence of these pulmonary conditions includes: 1) CD4 cell count-the most important determinant; 2) concurrent antimicrobial therapy; 3) prior travel history; 4) known latent infections that may reactivate: and 5) underlying respiratory disease. Specific pulmonary diseases are discussed including: bacterial pneumonia, bronchitis, mycobacterial and fungal infections, pneumocystis carinii pneumonia, toxoplasmosis, cytomegalovirus, Kaposi sarcoma, lymphoma, and lung cancer. A differential diagnosis can be generated based on the chest radiographic pattern. Focal or multifocal areas of consolidation usually represent conventional bacterial pneumonia or, less commonly, tuberculosis. In severely immunocompromised patients, unusual diseases causing consolidation should be considered including: Rhodococcus infection, nocardiosis, cryptococcosis, aspergillosis, and lymphoma. Nodules can be present in tuberculosis, histoplasmosis, cryptococcosis, and Kaposi sarcoma. Interstitial opacities are common in pneumocystis carinii pneumonia, histoplasmosis, and cytomegalovirus pneumonia. Cavitation and cysts are features of pneumocystis carinii pneumonia, tuberculosis, aspergillosis, and lung cancer. Disease of the airways is increasingly recognized in those with acquired immunodeficiency syndrome. Lymphadenopathy is most common in mycobacterial infection, but can be a feature of fungal infection, lymphoma, Kaposi sarcoma, and lung cancer. The combined use of clinical information, knowledge of typical conditions associated with the human immunodeficiency syndrome, and radiographic patterns offers a useful approach to the diagnosis of pulmonary disease in the patient with the human immunodeficiency virus.

Disease caused by Rhodococcus equi is a rare complication in subjects infected with human immunodeficiency virus (HIV) and it is associated with severe cellular immunodeficiency. The agent is gram-positive rod of the group non-diphtheric corynebacteria. The genus Rhodococcus belongs to the family Nocardiaceae and order Actinomycetales. The principle of pathogenicity is the survival inside macrophages. Formation of necrotising granulomas is a characteristic feature. Malacoplakia can be a specific cytological finding. Symptoms of disease include wet cough, fever and pleuritic chest pain. Problems persist many weeks before admission to the hospital. Chest X-ray and CT scan of the lungs show cavitary pulmonary lesions. Agents grow not only from the sputum specimen and also from samples received by bronchoscopy. In 50% of cases it can be revealed in hemoculture. Outcome is poor; mortality rate is reported to be over 30%. Better survival can be found in subjects who managed efficient antiretroviral therapy. Recommended treatment of Rhodococcus equi pneumonia includes particularly vancomycin, amikacin, rifampicin, imipenem, ciprofloxacin and erythromycin. Rhodococcus equi infection in an HIV positive subject is reported in case study of 52-year old man with AIDS with cavitary necrotising pneumonia and induced pericarditis, where the agent grew in hemoculture. This Rhodococcus equi pneumonia is the first case and till now the only one Rhodococcus infection in HIV patients described in the Czech Republic.
