[Pneumonia due to a rare atypical Mycobacterium in AIDS].
A 38-year-old man, HIV-positive for 6 years, developed fever and cough with deterioration in his general state. Chest radiography demonstrated an infiltration in the left upper lobe and computed tomography showed a septated cavity. Three bronchioalveolar lavages over 4 weeks recovered Klebsiella, Candida, Pseudomonas and Staphylococcus in the lavage fluid. Acid-fast rods were not found in any of the microscopic preparations. His clinical condition and the radiological findings deteriorated despite appropriate antibiotic administration. A further cavity occurred in the right upper lobe and the inflammatory infiltrations extended further. Although no acid-fast organism had been demonstrated, tuberculostatic treatment was begun (daily 300 mg isoniazid, 600 mg rifampicin, 900 mg streptomycin, 2 g pyrazinamide). His general condition and the radiological findings rapidly improved. Four weeks after culturing the lavage fluid atypical Mycobacterium xenopi was isolated. This case illustrates the difficulty of diagnosing an atypical mycobacterial infection. It takes time and effort, but it is of great importance because up to 50% of patients with AIDS contract such infection. Early and appropriate treatment will significantly improve quality of life and life expectancy.
