Despite widespread use of the bacille Calmette-Guérin (BCG) vaccine, tuberculosis (TB) remains a leading cause of global mortality from a single infectious agent (Mycobacterium tuberculosis or Mtb). Here, over two independent Mtb challenge studies, we demonstrate that subcutaneous vaccination of rhesus macaques (RMs) with rhesus cytomegalovirus vectors encoding Mtb antigen inserts (hereafter referred to as RhCMV/TB)-which elicit and maintain highly effector-differentiated, circulating and tissue-resident Mtb-specific CD4+ and CD8+ memory T cell responses-can reduce the overall (pulmonary and extrapulmonary) extent of Mtb infection and disease by 68%, as compared to that in unvaccinated controls, after intrabronchial challenge with the Erdman strain of Mtb at ∼1 year after the first vaccination...

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is emerging as a major public health problem globally. Treatment success rates in MDR-TB across the globe are not encouraging as completing MDR-TB treatment successfully is challenging due to high proportion of lost to follow up. METHODS: Using qualitative methods and grounded theory approach, in-depth interviews were conducted with MDR-TB patients and treatment providers. The social cognitive framework was explored as a way to guide understanding of the factors affecting treatment adherence among MDR-TB patients...

Tuberculosis (TB) is the major threat for humans from past several decades. Even after advent of several antitubercular drugs, researchers are still struggling for the mycobacterial infections in humans are TB and leprosy. Chronic infections caused by Mycobacterium tuberculosis and Mycobacterium leprae. A particular problem with both of these organisms is that they can survive inside macrophages after phagocytosis, unless these cells are activated by cytokines produced by T-lymphocytes, because of this researchers are not yet succeeded in finding effective treatment on TB...

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...

High global prevalence of latent TB infection (LTBI) is a key challenge in distinguishing patients with active pulmonary TB (PTB) from those with LTBI. The functional profile of CD4+ and CD8+ T cell cytokines produced as a response to Mycobacterium tuberculosis antigens vary during the course of tuberculosis (TB) infection. We evaluated antigen-specific CD4+ and CD8+ T cell cytokine response after overnight in vitro stimulation of peripheral blood with mycobacterial antigens ESAT-6, CFP-10, Rv2204c, Rv0753c and Rv0009 by flow cytometry...

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...

The independent Technical Review Panel (TRP) of the Global Fund to Fight HIV/AIDS, Tuberculosis and Malaria is a unique mechanism to review funding proposals and to provide recommendations on their funding. Its functioning and performance have received little attention in the scientific literature. We aimed to identify predictors for TRP recommendations, whether these were in line with the Global Fund's ambition to give priority to countries most in need, and whether they correlated with grant performance. We combined data on proposals and applications under the Rolling Continuation Channel, TRP recommendations and grant implementation during the rounds-based mechanism (2002-2010) with country characteristics...

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)...

In countries with low and moderate incidence of tuberculosis (TB), the disease tends to concentrate in specific high-risk populations such as people with diabetes mellitus (DM). We review the updated evidence on the association between 1) DM and active TB, and 2) DM and latent tuberculous infection (LTBI), and 3) we summarize the findings on the population-level impact of DM on TB epidemiology, with particular focus on low- and moderate-incidence settings. We conducted an updated review of studies on DM and active TB, and found 11 more cohort studies published after the previous systematic review from 2008...

Tuberculosis (TB) remained as one of the top 10 causes of death worldwide despite an overall decline in its incidence rate globally. Extrapulmonary TB is uncommon and only accounts for 10-20% of overall TB disease burden. Abdominopelvic TB is the sixth most common location of extrapulmonary TB. The symptoms and signs are often insidious and nonspecific. Diagnosing abdominopelvic TB can be very challenging at times and poses great difficulties to the clinician. Infection with nontuberculous Mycobacterium (NTM) is even rarer especially in an immunocompetent patient...

Granulomas are hallmarks of pulmonary tuberculosis (TB) and traditionally viewed as host-protective structures. However, recent evidence suggest that Mycobacterium tuberculosis (Mtb) uses its virulence factors to stimulate the formation of granuloma. In the present study, we investigated the contribution of matrix metalloproteinases (MMPs), host enzymes that cause degradation of the extracellular matrix, to granuloma formation and bacterial load in Mtb-infected tissue. To this end, we used our lung tissue model for TB, which is based on human lung-derived cells and primary human monocyte-derived macrophages...
