BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) is associated with substantial morbidity, despite drug therapy. Interferon-gamma, a cytokine produced mainly by CD4 T lymphocytes, can activate alveolar macrophages, important effector cells in host immunity against Mycobacterium tuberculosis. We investigated safety and tolerability of aerosolised(More)
Local cellular immune responses may affect presentation and outcome in tuberculosis (TB). To investigate this hypothesis, we performed bronchoalveolar lavage (BAL) on 30 patients with untreated pulmonary tuberculosis and assessed the type of cellular inflammatory response and cytokine production. We then correlated BAL findings and cytokine production with(More)
A variety of neuropharmacological strategies are being pursued in the search for an effective treatment for methamphetamine (Meth) addiction. In this study, we investigated the safety and potential efficacy of aripiprazole, an antipsychotic agent acting on both dopamine and serotonin systems. We conducted a double-blind in-patient clinical pharmacology(More)
BACKGROUND Tuberculosis (TB) causes 1.45 million deaths annually world wide, the majority of which occur in the developing world. Active TB disease represents immune failure to control latent infection from airborne spread. Acid-fast bacillus (AFB) seen on sputum smear is a biomarker for contagiousness. METHODS We enrolled 73 tuberculosis patients with(More)
BACKGROUND There is a need for rapid diagnosis of pulmonary tuberculosis. We have previously used a PCR to detect circulating Mycobacterium tuberculosis DNA in blood samples from patients (mostly HIV-infected) with pulmonary tuberculosis. We have now prospectively investigated the role of this blood-based PCR assay for diagnosis of this disease in a(More)
Gamma interferon (IFN-gamma) is critical in the immune response against Mycobacterium tuberculosis. In an ongoing trial of aerosol IFN-gamma in conjunction with standard drug therapy, we have observed activation of IFN signaling in bronchoalveolar lavage (BAL) cells from tuberculosis (TB) patients. We hypothesized that aerosol IFN-gamma treatment of(More)
Sputum examination for rapid diagnosis of pulmonary tuberculosis is not always satisfactory. We examined peripheral blood with the polymerase chain reaction (PCR). Blood samples were collected from 8 consecutive patients with suspected pulmonary tuberculosis and from 18 healthy controls, half of whom were tuberculin skin-test positive. All 8 patients had(More)
BACKGROUND Current treatment regimens for pulmonary tuberculosis require at least 6 months of therapy. Immune adjuvant therapy with recombinant interferon-gamma1b (rIFN-gammab) may reduce pulmonary inflammation and reduce the period of infectivity by promoting earlier sputum clearance. METHODOLOGY/PRINCIPAL FINDINGS We performed a randomized, controlled(More)
