A case of Aspergillus empyema successfully treated with combination therapy of voriconazole and micafungin: excellent penetration of voriconazole and micafungin into pleural fluid.

A 62-year-old man with empyema caused by Aspergillus fumigatus was successfully treated with a combination of voriconazole (VRCZ) and micafungin (MCFG). Data regarding the penetration of antifungal agents into pleural fluid are limited. Thus, we measured the concentration of VRCZ and MCFG in his plasma and pleural fluid. Penetration of VRCZ and MCFG into the pleural fluid was excellent. Therefore, the combination therapy using VRCZ and MCFG may contribute to successful management of Aspergillus empyema.

Clinical and pathological findings of interstitial lung disease patients with anti-aminoacyl-tRNA synthetase autoantibodies.

OBJECTIVE: The aim of this study was to investigate the clinicopathological characteristics of interstitial lung disease (ILD) patients with anti-aminoacyl-tRNA synthetase (anti-ARS) autoantibodies. Patients and Methods We examined 14 ILD patients with anti-ARS autoantibodies between 2004 and 2007 and retrospectively investigated their clinical, radiographic, and pathological findings. RESULTS: Anti-Jo-1 antibodies were the most common (10 of 14), followed by anti-OJ, anti-KS, and anti-EJ (1 each for 3 patients); 1 patient with polymyositis had both anti-Jo-1 and anti-PL-12 antibodies. Ten patients had a chronic clinical course, whereas 4 presented with subacute deterioration. Of 8 patients with myositis, 1 (12.5%) had myositis-preceding ILD, 3 (37.5%) had ILD-preceding myositis, and 4 (50%) had simultaneous onset. Chest high-resolution computed tomography frequently showed lung-base predominant ground glass opacities (GGO) with volume loss. The results of surgical lung biopsies indicated that 4 patients had nonspecific interstitial pneumonia (NSIP) and/or organizing pneumonia (OP) patterns. All but 1 received corticosteroid therapy, and 6 patients were also given cyclosporin. The mean duration of follow-up was 22 months (range, 5-47 months). ILD improved in 9 patients and stabilized in 3; however, in 1 patient, it initially improved during 6 months, then progressively worsened despite treatment, and finally resulted in death. CONCLUSION: These results indicate that ILD patients with anti-ARS antibodies usually have a chronic clinical course, lung-base predominant GGO with volume loss, NSIP and/or OP patterns, and a good response to corticosteroid treatment; however, some have a rapidly worsening course and recurrence, despite therapy.

[A possible case of drug-induced pneumonia due to L-carbocisteine].

A 70-year-old man presented with a deteriorating fever and productive cough after the administration of drugs including L-carbocisteine against the common cold. Since chest radiograph revealed pulmonary infiltrates in the right lower lung field, he was admitted to our hospital, then L-carbocisteine was continued and antibiotics started. However, his symptoms, laboratory findings, and hypoxia worsened. Pulmonary infiltrates on his chest radiograph increased and chest CT demonstrated pulmonary consolidation with traction bronchiectasis and ground glass opacity with thickened of interlobular septae in the right lung field. Analysis of bronchoalveolar lavage fluid showed elevated numbers of total cells, neutrophils and eosinophils, and the CD4/CD8 ratio was 5.65. Under a suspected diagnosis of drug-induced pneumonia, we halted L-carbocisteine administration stopped and began corticosteroid therapy. Subsequently his symptoms and findings markedly improved. The drug lymphocyte stimulation test for L-carbocisteine using peripheral blood lymphocytes showed positive results. On the basis of the clinical course, laboratory and radiographic findings, we considered this case to possibly be drug-induced pneumonia due to L-carbocisteine. To our knowledge, this is possibly the first case of L-carbocisteine-induced pneumonia to be reported.

Use of tiotropium bromide for pre-operative treatment in chronic obstructive pulmonary disease patients: comparison with oxitropium bromide.

OBJECTIVE: Chronic obstructive pulmonary disease (COPD), which ranks fifth in terms of the global burden of diseases, is one of the major risk factors of post-operative pulmonary complications. Tiotropium bromide is a new inhaled bronchodilator for COPD patients with a sustained duration of action; it has superior efficacy compared to other bronchodilators. However, little is known regarding its clinical value as a preoperative treatment for COPD patients. In this study, we compared the incidence of post-operative complications between COPD patients who received with tiotropium bromide and those who did not. METHODS: Retrospective study. PATIENTS: For 1 month before surgery we examined 84 and 82 patients treated with tiotropium bromide (tiotropium group) and oxitropium bromide (oxitropium group), respectively, in combination with other medications. We performed a statistical comparison of clinical features, pulmonary functions, and postoperative complications between the 2 groups. RESULTS: The improvements in clinical symptoms and forced expiratory volume in 1 second were better in the tiotropium group than in the oxitropium group. The incidence of post-operative pulmonary complications (refractory bronchospasm, pulmonary infection, and acute respiratory failure) was significantly lower in the tiotropium group than in the oxitropium group. Three patients in the tiotropium group complained of dry mouth; however, the symptoms could be controlled. The incidence of post-operative non-pulmonary complications was not significantly different between the 2 groups. CONCLUSION: We propose that tiotropium bromide might be a safe and useful drug for pre-operative treatment of COPD patients.

Two cases of acute exacerbation of interstitial pneumonia treated with polymyxin B-immobilized fiber column hemoperfusion treatment.

The effect of polymixin B-immobilized fiber column (PMX) hemoperfusion treatment for acute exacerbation of interstitial pneumonia (IP) has been reported. Here, we report 2 cases of acute exacerbation of IP successfully treated with PMX hemoperfusion. One is a 55-year-old woman who was diagnosed as microscopic polyangiitis (MPA) with IP. The other is a 58-year-old man, diagnosed as having idiopathic pulmonary fibrosis. Both cases were treated with PMX hemoperfusion and other therapies. One died on day 44 and the other is still alive. The PMX hemoperfusion treatment decreased the serum levels of several cytokines and activated neutrophil percentage in bronchoalveolar lavage fluid.
