RATIONALE Isoniazid given daily for 9 months is the standard treatment for latent tuberculosis infection (LTBI), but its effectiveness is limited by poor completion rates. Shorter course regimens and regimens using directly observed therapy result in improved adherence but have higher upfront costs. OBJECTIVES To evaluate the costs and cost-effectiveness(More)
SETTING Twenty tuberculosis (TB) clinics in the United States and Canada. OBJECTIVE To evaluate the efficacy and safety of a 6-month intermittent regimen of rifampin (RMP), pyrazinamide (PZA) and ethambutol (EMB) in human immunodeficiency virus (HIV) negative patients with culture-confirmed pulmonary or extra-pulmonary tuberculosis and either isoniazid(More)
Collagen-vascular diseases are associated with immune dysregulation and inflammation, leading to tissue destruction or compromise. Immunosuppression is more commonly associated with the drugs used to treat these disorders than with the diseases themselves. The newest agents being used to treat collagen-vascular diseases are the tumor necrosis factor(More)

One hundred fourteen patients received rifampin/pyrazinamide in Wake County, North Carolina, between December 1999 and May 2002; 60.5% of these patients were homeless, and(More)
Tuberculosis (TB) is a global public health problem and a source of preventable deaths each year, with 8.8 million new cases of TB and 1.6 million deaths worldwide in 2005. Approximately, 10% of infected individuals develop pulmonary or extrapulmonary TB, suggesting that host defense factors influence development of active disease. Toll-like receptor' (TLR)(More)
Tuberculosis (TB) has substantial mortality worldwide with 5-10% of those exposed progressing to active TB disease. Studies in mice and humans indicate that the inducible nitric oxide synthase (iNOS) molecule plays an important role in immune response to TB. A mixed case-control association study of individuals with TB, relatives, or close contact controls(More)
BACKGROUND The proportion of extrapulmonary tuberculosis (EPTB) reported in the United States has been gradually increasing. HIV infection and foreign birth are increasingly associated with tuberculosis and understanding their effect on the clinical presentation of tuberculosis is important. METHODS Case-control study of 6,124 persons with tuberculosis(More)
To determine the effect of omeprazole on peak serum concentrations (C(max)) of itraconazole oral solution (IOS), we carried out a randomized, open-label, prospective, crossover study. Fifteen healthy, non-pregnant adults received a single dose of IOS 400 mg on two occasions, at least 7 days apart, with omeprazole 40 mg nightly for 7 days before either IOS(More)
