The broadest pattern of tuberculosis (TB) drug resistance for which a consensus definition exists is extensively drug-resistant (XDR)-TB. It is not known if additional drug resistance portends worsened patient outcomes. This study compares treatment outcomes of XDR-TB patients with and without additional resistance in order to explore the need for a new definition. Individual patient data on XD...
BACKGROUND & OBJECTIVES Pre-extensively drug resistant (pre-XDR) and extensively drug resistant tuberculosis (XDR-TB) have been areas of growing concern, and are posing threat to global efforts of TB control. The present study was planned to study the presence of pre-XDR and XDR Mycobacterium tuberculosis and their genotypes in clinical isolates obtained from previously treated cases of pulmona...
The emergence of drug-resistant tuberculosis (TB) is a challenge to TB control in Europe. We evaluated second-line drug susceptibility testing in Mycobacterium tuberculosis isolates from patients with multidrug-resistant, pre-extensively drug-resistant (pre-XDR-TB) and XDR-TB at 23 TBNET sites in 16 European countries. Over 30% of bacilli from patients with pre-XDR-TB showed resistance to any f...
Emergence of extensively drug resistant tuberculosis (XDR-TB) has been reported by more than 55 countries. XDR-TB is considered as untreatable and highly fatal disease. In developing countries like India, number of cases of multi-drug resistant tuberculosis (MDR-TB) and XDR-TB are increasing. Emergence of resistance to Isoniazid and Rifampicin, the two most effective and well tolerated agents, ...
The emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) has raised public health concern about global control of TB. To estimate the transmission dynamics of MDR and XDR TB, we conducted a DNA fingerprinting analysis of 55 MDR/XDR Mycobacterium tuberculosis strains isolated from TB patients throughout Japan in 2002. Twenty-one (38%) of the st...
Multidrug resistant pathogens are a widespread problem in the hospital setting especially on intensive care units (ICU). This study evaluated the susceptibility of clinical isolates of gramnegative extensively drug resistant organisms (XDR), methicillinresistant Staphylococcus aureus (MRSA), and vancomycin-resistant Enterococcus (VRE) to a proprietary chlorhexidine digluconate (CHG) formulation...
conclusions the population structure of the a. baumannii isolates in our hospitals was genetically diverse. a significant association between xdr pattern and presence of class 1 integron (p < 0.001) was found indicating that many antibiotic resistance determinants are involved in development of xdr strains. materials and methods during a three-year study, clinical isolates of a. baumannii were ...
زمینه و اهداف: انسان خود باعث پیدایش سل مقاوم به دارو شده است. پیدایش جهانی XDR-TB نخستین بار در سال 2005 میلادی گزارش شد. XDR-TB فرمی از مقاومت دارویی است که در آن باسیل سل علاوه بر انکه حداقل به 2 داروی مهم و اصلی ضد سل (ایزونیازید و ریفامپین) مقاوم است. به یک فلوروکوئینولون و حداقل به سه داروی تزریقی امیاکسین،کانامایسین و کاپرئومایسین مقاوم است. با توجه به اینکه میزان XDR-TB به سرعت رو به گ...
OBJECTIVE To determine prevalence of extensively drug resistant tuberculosis (XDR-TB) in Chest Disease Institute. World Health Organization has given the definition of XDR-TB as multi-drug resistant tuberculosis which also resists fluoroquinolone and aminoglycoside. MATERIAL AND METHOD The present study was a retrospective review and conducted at Microbiology Unit, Chest Disease Institute. Dr...
SETTING Drug-resistant tuberculosis (TB) is an important public health problem in Latvia. OBJECTIVE To document trends, characteristics and treatment outcomes of registered patients with multi-drug-resistant (MDR-) and extensively drug-resistant (XDR-) TB in Latvia from 2000 to 2010. DESIGN A retrospective national cohort study. RESULTS Of 1779 patients, 1646 (92%) had MDR- and 133 (8%) X...
