The in vitro activities of cloxyquin (5-chloroquinolin-8-ol) against 9 standard strains and 150 clinical isolates of Mycobacterium tuberculosis were studied. The MICs ranged from 0.062 to 0.25 microg/ml. The MIC(50) and MIC(90) were 0.125 and 0.25 microg/ml, respectively. These indicate that cloxyquin exhibited good antituberculosis activity, even for multidrug-resistant isolates.

OBJECTIVES This study aimed to characterize and estimate the frequency of adverse reactions to antituberculosis drugs in the population treated at the Centro de Saúde Escola Germano Sinval Faria, a primary health care clinic in Manguinhos, Rio de Janeiro City, and to explore the relationship between adverse drug reactions and some of the patients' demographic and health characteristics. METHO...

central nervous system’s disorders including chronic meningitis (cm) have considerable mortality and irreversible complications, and diagnosis and treatment of cm is difficult. in this retrospective study we reviwed epidemiological and clinical findings, treatment results and prognostic factors of 97 patients with cm admitted in imam khomeini hospital for the last 10 years. important etiologica...

The nitroimidazopyran PA-824 has potent in vitro activity against Mycobacterium tuberculosis, a narrow spectrum of activity limited primarily to the M. tuberculosis complex, and no demonstrable cross-resistance to a variety of antituberculosis drugs. In a series of experiments, we sequentially characterized the activity of PA-824 in an experimental murine model of tuberculosis. The minimal effe...

Fluoroquinolones, which are widely used to treat community-acquired pneumonia, also have excellent in vitro activity against Mycobacterium tuberculosis. A retrospective cohort study was conducted among adults with culture-confirmed tuberculosis to assess the effect of empiric fluoroquinolone therapy on delays in the treatment of tuberculosis. Sixteen (48%) of 33 patients received fluoroquinolon...

The main objectives of tuberculosis therapy are to cure the patients and to minimize the possibility of transmission of the bacillus to healthy subjects. Adverse effects of antituberculosis drugs or drug interactions (among antituberculosis drugs or between antituberculosis drugs and other drugs) can make it necessary to modify or discontinue treatment. We describe the general mechanism of acti...

Tuberculosis is a major infectious disease that requires prolonged chemotherapy with a combination of four drugs. Here we present data suggesting that treatment of Mycobacterium tuberculosis, the causative agent of tuberculosis, and Mycobacterium smegmatis, a model organism widely used for the screening of antituberculosis agents, with first-line drugs resulted in the generation of substantial ...

conclusions according to the presented case and subsequent literature review on fatal ebv hepatitis, clinicians should consider ebv infection in the differential diagnosis when hepatitis occurs in critically ill patients during the anti-tb therapy. although hepatitis caused by ebv is mostly self-limited, some might be fetal. introduction although hepatitis is frequently observed during antitube...
