    Abstract:
    BACKGROUND: Pneumonia by Rhodococcus equi is infrequent and is associated with patients with important immunosuppression. To date 66 cases of pneumonia by Rhodococcus equi in patients with HIV infection have been published. The diagnosis, problems in determining diagnosis and treatment are discussed. MATERIALS AND METHODS: Two new cases of pneumonia by Rhodococus equi in C3 stage patients with HIV infection are reported. Diagnosis was achieved by study of bronchoalveolar lavage samples with the Apy-Coryne method and gas chromatography. RESULTS: The two patients presented pneumonia, one of which was necrotizing pneumonia with localization in the upper left lung and in the lower right lung, respectively. The clinical manifestations were characterized by respiratory involvement of a subacute course with pleural involvement in both cases and hemoptisis in one. Prolonged, combined antibiotic treatment was administered with good response in both cases. One patient died at one year of diagnosis from consumptive syndrome while the other remains asymptomatic. CONCLUSIONS: Infection by Rhodococcus equi should be suspected in HIV patients with slow evolution pneumonia, especially in the pneumonia is necrotizing. Combined i.v. antibiotic treatment is recommended and followed from 3 to 5 months with an association including clarithromycin.
