Cases of active tuberculosis have been reported worldwide with the use of therapeutic agents that inhibit tumour necrosis factor (TNF) alpha. TNFalpha has a central role in mycobacterial infection and disease. Accordingly, progression of recently acquired tuberculosis infection or reactivation of remotely acquired infection should be expected with the use(More)
Tuberculosis as a primary cause of respiratory failure requiring mechanical ventilation (TBMV) is an uncommon occurrence. Over a 10 yr period in the province of Manitoba, Canada (population 1,091,942 in 1991), 13 patients with TBMV were identified. Non-drug-resistant M. tuberculosis was isolated from each case. The patients fell into two categories: miliary(More)
To test the hypothesis that antituberculous drug disposition is altered in patients with AIDS, we studied the steady-state pharmacokinetics of isoniazid (300 mg/d), rifampin (600 mg/d), and pyrazinamide (1,500 mg/d) in 29 adults (14 patients infected with human immunodeficiency virus [HIV] and 15 non-HIV-infected patients) with tuberculosis in Nairobi,(More)
We tested the hypothesis that exposure of extracellular Mycobacterium tuberculosis to low concentrations (< 100 ppm) of nitric oxide (NO) for short periods (24 h or less) will result in microbial killing. We observed that NO had both dose- and time-dependent cidal effects that were very significant by two-way analysis of variance (F ratios of 13.4 [P <(More)
OBJECTIVES (1) To correlate structure (CT) with function in pulmonary tuberculosis (TB), and (2) to describe the evolution of structural and functional abnormalities when pulmonary TB is treated with directly observed therapy. SUBJECTS AND METHODS Twenty-five patients with drug-susceptible pulmonary TB, 15 cavitary and 10 noncavitary, were studied(More)
To define the epidemiology, pathogenesis, pathology, presentation, and management of tuberculous mycotic aneurysm of the aorta (TBAA) in the therapeutic era, we reviewed all of the cases reported in the English language literature from 1945 to the present. To the 39 cases in the published literature, we add two cases of our own. Although it is exceedingly(More)
Many vaccine-preventable diseases have serious consequences for the pregnant mother, the fetus, and the neonate. This article reviews the rationale and impact of including vaccinations as part of preconception care and provides recommendations for clinical care. Vaccinations that are recommended highly in preconception care include the hepatitis B and the(More)
BACKGROUND Treatment of latent tuberculosis infection with isoniazid for 9 months is complicated by poor patient adherence and the need for close follow-up of side effects, especially hepatotoxicity. Shorter and safer regimens are needed. OBJECTIVE To compare the frequency of adverse events and treatment completion in 2 treatment regimens for latent(More)
To determine the epidemiology and clinical features of disease due to nontuberculous mycobacteria (NTM) in our institution, we reviewed the medical records of all patients from whom NTM isolates were recovered from 1988 to 1990 to extract selected clinical and laboratory data. On the basis of the likelihood of infection, patients were classified as having(More)
