BACKGROUND The prevalence of extensively drug-resistant (XDR) tuberculosis is increasing due to the expanded use of second-line drugs in people with multidrug-resistant (MDR) disease. We prospectively assessed resistance to second-line antituberculosis drugs in eight countries. METHODS From Jan 1, 2005, to Dec 31, 2008, we enrolled consecutive adults with… (More)
Data from a large multicenter observational study of patients with multidrug-resistant tuberculosis (MDR TB) were analyzed to simulate the possible use of 2 new approaches to treatment of MDR TB: a short (9-month) regimen and a bedaquiline-containing regimen. Of 1,254 patients, 952 (75.9%) had no resistance to fluoroquinolones and second-line injectable… (More)
The purpose of this study was to assess the performance of Cepheid® Xpert MTB/RIF® (“Xpert”) and TB-Biochip® MDR (“TB-Biochip”). Sputum specimens from adults with presumptive tuberculosis (TB) were homogenized and split for: (1) direct Xpert and microscopy, and (2) concentration for Xpert, microscopy, culture [Lowenstein–Jensen (LJ) solid media and… (More)
BACKGROUND For treating multidrug-resistant tuberculosis (MDR TB), the World Health Organization (WHO) recommends a regimen of at least four second-line drugs that are likely to be effective as well as pyrazinamide. WHO guidelines indicate only marginal benefit for regimens based directly on drug susceptibility testing (DST) results. Recent evidence from… (More)
Intravenous infection of C57Bl/6 female mice with M. tuberculosis H37Rv led to involvement of the lungs and dissemination of the tuberculous infection to the abdominal and pelvic organs. M. tuberculosis were detected in the lungs and spleen in 14, 35, and 90 days and in the uterine horns in 90 days after infection. Morphological analysis of organs showed… (More)
This document summarizes priority areas for joint research and concerted actions to counteract the public health threat of AIDS/TB as identified within the European Support Action " EUCO-Net " funded under the 7 th Framework Programme of the European Commission.
This report details the main findings of research of latest available data concerning epidemiological status of human immunodeficiency virus/ acquired immunodeficiency syndrome (HIV/AIDS) and M. tuberculosis (MTB) infections as well as HIV/MTB co-infection in support of Russian Federation (RF) Country Report for the EUCO-Net project on global cooperation in… (More)
