Currently, the standard short-course chemotherapy for tuberculosis comprises a 6-month regimen, with a four-drug intensive phase and a two-drug continuation phase. Alternative chemotherapy using more costly and toxic drugs, often for prolonged durations generally >18 months, is required for multidrug-resistant and extensively drug-resistant tuberculosis.(More)

We studied the differences in liver dysfunction observed during anti-TB treatment between hepatitis B virus carriers (HBV) and noncarriers. Three hundred twenty-four patients on anti-TB drugs were recruited and followed up for 1 year. Forty-three patients with HBV and 276 non-HBV(More)

Serum IgG against H. pylori was therefore measured prospectively in consecutive subjects with bronchiectasis (n = 100; mean age +/- SD 55.1 +/- 16.7 yr), active pulmonary tuberculosis (n = 87; age, 57.3 +/- 19.1 yr), and healthy(More)
