  • efficacy of clarithromycin and ethambutol for Mycobacterium Avium Complex pulmonary disease a preliminary study
    Annals of the American Thoracic Society, 2014
    Co-Authors: Seiichi Miwa, Masahiro Shirai, Kazumasa Yasuda, Masafumi Masuda, Mikio Toyoshima, Toshihiro Shirai, Naoki Inui, Koshi Yokomura, Takashi Yamada, Kingo Chida
    Abstract:

    Rationale: Patients with Mycobacterium Avium Complex pulmonary disease are frequently administered a combination of clarithromycin, ethambutol, and rifampicin. However, rifampicin is known to reduce the serum levels of clarithromycin. It remains unclear whether a reduction in clarithromycin serum levels influences the clinical outcome of the Mycobacterium Avium Complex pulmonary disease treatment regimen.Objectives: To compare a three-drug regimen (clarithromycin, ethambutol, and rifampicin) to a two-drug regimen (clarithromycin and ethambutol) for the treatment of Mycobacterium Avium lung disease.Methods: In a preliminary open-label study, we randomly assigned newly diagnosed, but as-yet untreated, patients with disease caused by Mycobacterium Avium Complex without HIV infection to either the three-drug or the two-drug regimen for 12 months. The primary endpoint was the conversion of sputum cultures to negative after 12 months of treatment. Patient data were analyzed using the intention-to-treat method.M...

  • Mycobacterium Avium Complex disease: prognostic implication of high-resolution computed tomography findings.
    The European respiratory journal, 2008
    Co-Authors: Shigeki Kuroishi, Masahiro Shirai, Kazumasa Yasuda, Yutaro Nakamura, Hiroshi Hayakawa, Y. Nakano, Takafumi Suda, Hidenori Nakamura, Kingo Chida
    Abstract:

    To evaluate the prognostic implications of computed tomography (CT) findings in assessing responses to treatment in Mycobacterium Avium Complex (MAC) pulmonary disease without underlying lung disease, high-resolution (HR)CT findings were correlated based on the results of sputum conversion after anti-MAC therapy. A total of 59 patients underwent HRCT before treatment and the therapeutic efficacy was evaluated by the results of sputum conversion. Atelectasis, cavities and pleural thickening on HRCT were significantly more frequent and extensive among patients in the sputum nonconverted group than among those in the converted group. Furthermore, bronchiectasis was also significantly more extensive among patients in the nonconverted group, even though there was no significant difference in frequency between these two groups. These results suggest that high-resolution computed tomography findings are good predictors of response to treatment in Mycobacterium Avium Complex pulmonary disease.
