The absence of the Holliday-junction Ruv resolvase of Mycobacterium smegmatis increased the bacteriostatic and bactericidal activities of the fluoroquinolone moxifloxacin, an important antituberculosis agent. The treatment of ruvAB-deficient cells with thiourea and 2,2'-bipyridyl lowered moxifloxacin lethality to wild-type levels, indicating that the absence of ruvAB stimulates a lethal pathway...

Tuberculous empyema (TE) is an uncommon form of pleural tuberculous (TB). Although the incidence of TE has significantly decreased, it still threatens public health. Patients with TE experience a protracted illness and significant morbidity and mortality risk. Male sex is a significant risk factor for TE. Herein, we report an adult case of TE admitted to a tertiary care hospital of Iran with cl...

recurrence of pulmonary tuberculosis and was started on the same four medications at a local clinic. One day after the initiation of this treatment, he noted jaundice, abdominal pain and oliguria. Admission laboratory data were as follows: blood urea nitrogen, 71.6mg/dl (25.5mmol/l); creatinine, 5.2mg/dl (459mmol/l); albumin, 4.0 g/dl (40 g/l); total bilirubin, 14.0mg/dl (238mmol/l); direct bil...

Sir—We read with great interest the study by Sacks et al. [1] regarding the use of adjunctive salvage therapy with inhaled aminoglycosides for the treatment of patients with persistent smear-positive pulmonary tuberculosis (TB). We would like to stress that such treatment may be microbiologically and also clinically effective in patients with refractory abscessed and cavitary pulmonary TB. In 1...

Background Tuberculosis (TB) is a disease that produces several million deaths annually. With the appearance of multi drug resistant microbial strains of Mycobacterium tuberculosis, innovations in TB drug discovery and evolving strategies to bring new agents with best performance is an essential investigation. Taking this into account, there is a pressing need to develop new and more effective ...

Therapeutic drug monitoring in tuberculosis remains controversial. We evaluated the relationship between antituberculosis drug levels in blood and clinical outcome. Serum concentrations of first-line antituberculosis drugs were measured in tuberculosis patients between March 2006 and April 2013. Venous blood was drawn 2 h after drug ingestion and was analyzed using high-performance liquid chrom...

The effects on ventricular repolarization-recorded on the electrocardiogram (ECG) as lengthening of the QT interval-of acute tuberculosis and those of standard and alternative antituberculosis regimens are underdocumented. A correction factor (QTc) is introduced to make the QT independent of the heart rate, translating into the slope of the regression line between QT and heart rate being close ...

OBJECTIVE To describe serum levels of the cytokines IL-10, TNF-α, and IFN-γ, as well as polymorphisms in the genes involved in their transcription, and their association with markers of the acute inflammatory response in patients with pulmonary tuberculosis. METHODS This was a descriptive, longitudinal study involving 81 patients with pulmonary tuberculosis treated at two referral hospitals. ...
