Further study details as provided by National Heart, Lung, and Blood Institute (NHLBI):

Primary Outcome Measures:
  • Sputum conversion (measured at Weeks 4 and 8)

Secondary Outcome Measures:
  • Chest CT scan
  • BAL to measure flow of cytometry and cytokine levels (measured at Month 4)

Estimated Enrollment: 96
Study Start Date: April 2005
Detailed Description:

BACKGROUND:

Mtb infects one-third of the world's population and ranks seventh in terms of global morbidity and mortality. Patients with bilateral pulmonary tuberculosis (TB), cavitary disease, and persistently positive sputum smears pose a special risk for treatment failure and/or relapse.

DESIGN NARRATIVE:

Cavitary pulmonary TB will be studied and interferon-gamma will be used as the intervention. The outcome of this study will be the changes in mycobacteriology, chest radiography, and bronchoalveolar lavage (BAL) cells.

The primary outcome will be sputum conversion, which will be measured at Weeks 4 and 8.

The key secondary outcomes of this study will include a chest computerized tomography (CT) scan and BAL to measure the flow of cytometry and cytokine levels. Both outcomes will be measured at baseline and at Month 4.
