Abstract:
We report 2 cases of pulmonary aspergillosis treated successfully by combining micafungin and traconazole. Case 1: A 51-year-old man with hemoptysis and dyspnea on effort treated for pulmonary tuberculosis and aspergillosis was found on chest CT on admission to have a fungus ball in the left upper lobe and increasing consolidation around the cavity of both lung fields. Bronchoscopy proved positive for aspergillus PCR in bronchial lavage. He was diagnosed with chronic necrotizing pulmonary aspergillosis, based on clinical and radiological findings and the positive reaction for aspergillus PCR. He was treated with micafungin alone at first, this proved ineffective, so itraconazole was added, resulting in improvement. Case 2: A 24-year-old woman with stabilized Hodgkin's disease (mixed). She had suffered from a cough and back pain, and chest CT showed increasing consolidation inside and around a giant bulla. She was diagnosed with chronic necrotizing pulmonary aspergillosis, based on isolation for Aspergillus sp. in sputum culture and a positive reaction for Aspergillus antigen in bronchial lavage and Aspergillus antibody in serum. She was treated with the combined micafungin and itraconazole, which rapidly improved symptoms and radiological findings. Pulmonary aspergillosis therapy is often difficult, because delivery of the drug to the infection site is limited and drug tolerance is poor. We found that combination micafungin and itraconazole therapy is tolerable and effective in these cases.

The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
