Unlike in pulmonary multidrug-resistant (MDR) tuberculosis, the clinical outcome of MDR tuberculous meningitis (TBM) in children, including extensively drug-resistant tuberculosis, is poor and management is challenging. We report the successful treatment of a case of extensively drug-resistant TBM in a 4-year-old girl, and we discuss implications for tuberculosis diagnosis and chemotherapy.

Despite the efforts made worldwide to reduce the number of cases of drug-susceptible tuberculosis, multidrug-resistant tuberculosis (MDR-TB) constitutes an important public health issue. Around 440,000 new cases of MDR-TB are estimated annually, although in 2008 only 7% of these (29,423 cases) were notified. The laboratory tests for diagnosing resistance may be phenotypic (based on culture grow...

Background: With almost 9 million new cases each year, tuberculosis remains one of the most feared diseases on the planet. Led by the STOP-TB Partnership and WHO, recent efforts to combat the disease have made considerable progress in a number of countries. However, the emergence of mutated strains of Mycobacterium tuberculosis that are resistant to the major antituberculosis drugs poses a dead...

Multidrug-resistant tuberculosis (MDR-TB) is a major concern in countries of the former Soviet Union. The reported risk of resistance among tuberculosis (TB) cases in the Republic of Moldova is among the highest in the world. We aimed to produce high-resolution spatial maps of MDR-TB risk and burden in this setting. We analysed national TB surveillance data collected between 2007 and 2010 in Mo...

Tuberculosis (TB) is a disease of worldwide public-health concern. The development of resistance to an increasing number of second-line drugs and those used to treat multidrug-resistant (MDR) TB is rapidly becoming an emergency that could hinder the prevention and treatment of TB globally. This study describes the resistance profile of MDR and extensively drug-resistant (XDR) TB with a hospital...

The correlation between resistance to pyrazinamide (PZA) and resistance to other first-line antituberculosis drugs was investigated in 395 Mycobacterium tuberculosis strains isolated from clinical specimens, representing 14% of the overall number of M. tuberculosis isolates obtained between 2003 and 2008 at the laboratory of a referral university hospital for tuberculosis. A high correlation wa...

Emergence of drug resistant tuberculosis like multi drug resistant tuberculosis (MDR-TB), extensively drug-resistant tuberculosis (XDR-TB) and totally drug resistant tuberculosis (TDR-TB) has created a new challenge to fight against these bad bugs of Mycobacterium tuberculosis. Repurposing and revival of the drugs are the new trends/options to combat these worsen situations of tuberculosis in t...

BACKGROUND Rapid and effective diagnosis of multidrug-resistant tuberculosis (MDR-TB) is an essential component of global tuberculosis (TB) control, but most MDR-TB cases are still not diagnosed. OBJECTIVE To assess whether patient sputum bacterial load can be used to identify patients at increased risk of MDR-TB. METHODS We used a case-control study and multivariable logistic regression mo...

BACKGROUND Multidrug resistance is a critical factor in tuberculosis control. To gain better understanding of multidrug resistant tuberculosis in Brazil, a retrospective study was performed to compare genotypic diversity and drug resistance associated mutations in Mycobacterium tuberculosis isolates from a national reference center. METHODS AND FINDINGS Ninety-nine multidrug resistant isolate...
