The global spread of non-tuberculous mycobacteria (NTM) may be due to HIV/AIDS and other environmental factors. The symptoms of NTM and tuberculosis (TB) disease are indistinguishable, but their treatments are different. Lack of research on the epidemiology of NTM infections has led to underestimation of its prevalence within TB endemic countries. This study was designed to determine the prevalence and clinical characteristics of pulmonary NTM in Bamako. A cross-sectional study which include 439 suspected cases of pulmonary TB...

Tuberculosis (TB) remains a global public health malady that claims almost 1.8 million lives annually. Diagnosis of TB represents perhaps one of the most challenging aspects of tuberculosis control. Gold standards for diagnosis of active TB (culture and nucleic acid amplification) are sputum-dependent, however, in up to a third of TB cases, an adequate biological sputum sample is not readily available. The analysis of exhaled breath, as an alternative to sputum-dependent tests, has the potential to provide a simple, fast, and non-invasive, and ready-available diagnostic service that could positively change TB detection...

A 26-year-old HIV-negative male from Ghana was treated for cervical, intrathoracic and abdominal lymph node tuberculosis (TB) and tuberculous hepatitis. Penetration of the thoracic trachea by a mediastinal lymph node had caused bronchomucosal TB. Sputum culture grew M. africanum, sensitive to all first-line antituberculous drugs. Four weeks after the beginning of directly observed treatment with isoniazid, rifampin, pyrazinamide and ethambutol, the right cervical lymph node increased in size, liquefied and caused a spontaneous fistula...

Mycobacterium abscessus lung disease is difficult to treat due to inducible resistance to macrolides. However, 15%-20% of isolates are macrolide susceptible. In 14 patients with macrolide-susceptible M. abscessus lung disease, all isolates had nonfunctional erm(41) gene, and sputum culture conversion rate was achieved in 93% (13/14) following antibiotic therapy.

Background: The global type 2 diabetes mellitus (DM) epidemic threatens progress made in reducing tuberculosis (TB)-related mortality worldwide. Previous clinical studies have not fully evaluated potential confounding variables in addressing the impact of DM on TB treatment outcomes. The antidiabetic agent metformin regulates autophagy and may play a role as a host-directed therapeutic adjuvant to antitubercular treatment. Methods: We conducted a retrospective cohort study comprising patients aged ≥13 years undergoing treatment for culture-confirmed, drug-susceptible pulmonary TB...

Our objective was to evaluate the efficacy of a standardised work-up in the diagnosis of pleural tuberculosis (TB) that included fibreoptic bronchoscopy and medical thoracoscopy. A consecutive series of 52 pleural TB patients observed during the period 2001-2015 was evaluated retrospectively. 20 females, mean (range) age 39.7 (18-74) years, and 32 males, mean (range) age 45.75 (21-83) years, were included (28 non-EU citizens (53.8%)). The diagnosis of TB infections was established by identification (using stains, culture or molecular tests) of Mycobacterium tuberculosis in the pleura, sputum and/or bronchial specimens, or by evidence of caseous granulomas on pleural biopsies...

BACKGROUND: The non-tuberculous mycobacteria include those mycobacterium species that are not members of the Mycobacterium tuberculosis complex, the causative agent of pulmonary tuberculosis and Mycobacterium leprae. In Zambia, Non-tuberculous Mycobacteria are gaining recognition as pathogens of public health significance. However, there is scanty information on the isolation and speciation of these organisms for better patient management, consequently reducing the burden of these infections...

There is a growing awareness that molecular diagnostics for detect-to-treat applications will soon need a highly multiplexed mutation detection and identification capability. In this study, we converted an open-amplicon MDR-TB microarray hybridization test into an entirely closed-amplicon consumable (an amplification microarray) and evaluated its performance on matched sputum and sediment extracts. Reproducible genotyping (LoD) was achieved with ∼25 MTB genomes (100 fg of MTB DNA) per reaction; the estimated shelf life of the test was least 18 months when stored at 4°C...

Introduction: Globally, Xpert MTB/RIF (Xpert) is the most widely-used PCR test for tuberculosis (TB). Positive results in previously-treated patients, which are due to old DNA or active disease, are a diagnostic dilemma.Materials and methods: We prospectively re-tested sputum from 238 patients, irrespective of current symptoms, who were previously-diagnosed as Xpert-positive and treated successfully. Patients who re-tested as Xpert-positive, culture-negative were exhaustively investigated (repeated culture, chest radiography, bronchoscopy with bronchoalveolar lavage, long-term clinical follow-up)...

Bordetella pertussis isolation by culture has low detection sensitivity for diagnosing pertussis; the diagnosis is confirmed by measuring serum anti-pertussis toxin (anti-PT) or anti-filamentous hemagglutinin antibody titers, and by genetic testing (polymerase chain reaction/loop-mediated isothermal amplification). Isolation of B. pertussis in adults is difficult, resulting in a delayed diagnosis, as a delayed cough may present ≥3 months after onset. Differentiation from bronchial asthma is also important...

Djibouti is a small country in the Horn of Africa with a high TB incidence (378/100,000 in 2015). Multidrug-resistant TB (MDR-TB) and resistance to second-line agents have been previously identified in the country but the extent of the problem has yet to be quantified. A national survey was conducted to estimate the proportion of MDR-TB among a representative sample of TB patients. Sputum was tested using XpertMTB/RIF and samples positive for MTB and resistant to rifampicin underwent first line phenotypic susceptibility testing...
