The individual- and population-level impact of household tuberculosis exposure on transmission is unclear but may have implications for the effectiveness and implementation of control interventions. We systematically searched for and included studies in which latent tuberculosis infection was assessed in 2 groups: children exposed and unexposed to a household member with tuberculosis. We also extracted data on the smear and culture status of index cases, the age and bacillus Calmette-Guérin vaccination status of contacts, and study design characteristics...

Tuberculosis (TB) in young children differs from adult TB in that the risk of rapid progression to active TB (aTB) is higher in children than in adults. The reasons for this increased risk are not fully understood. Early differentiation remains difficult between children at risk to develop aTB from those who will remain healthy and develop a latent TB infection (LTBI). Biomarkers to differentiate aTB from LTBI in children, especially in very young children, are urgently needed. To identify M. tuberculosis-specific functional T cell subsets related to clinical manifestations in children, we enrolled 87 children exposed to M...

BACKGROUND: Data regarding the use of QuantiFERON to assist the diagnosis of active tuberculosis (TB) in HIV-infected children is limited, especially in countries with low incidence of TB/HIV co-infection. METHODS: QuantiFERON results were analyzed in 63 HIV-infected children who presented to our hospital in Paris, France. Seventeen HIV-uninfected children with active TB (4 culture-confirmed) were included for comparison. RESULTS: The 63 HIV-infected children (median age: 11 years) had 113 QuantiFERON tests...

Tuberculosis control relies on the identification and preventive treatment of people who are latently infected with Mycobacterium tuberculosis (Mtb). PE/PPE proteins have been reported to elicit CD4 and/or CD8 responses either in the form of whole recombinant proteins or as individual peptides. Very few of the PE and PPE proteins have been previously tested for responses in patients with TB and healthy donors. This is the first study to evaluate the Interferon Gamma Release Assay (IGRA) after stimulation with PE35 and PPE68...

There is uncertainty regarding whether patients with cancer should be screened for latent tuberculosis infection (LTBI). We performed a systematic review and meta-analysis to estimate the relative incidence of tuberculosis (TB) in cancer.We searched MEDLINE and Embase for studies published before December 21, 2016. We included studies that evaluated the incidence of TB in patients with solid cancers and haematological malignancies relative to a reference group (study control or general population). A pooled estimate of the incidence rate ratio (IRR) was obtained using standard meta-analysis methods...

BACKGROUND: Children less than five years of age have the highest age-specific rate of progression from latent tuberculosis infection (LTBI) to active disease. Therefore, regimens for treatment of pediatric LTBI must be not only efficacious but practical enough to overcome the unique childhood barriers to regimen adherence. Since 2012, a 4-month regimen of daily rifampin (4R) has been the standard recommendation for pediatric LTBI at the Denver Metro Tuberculosis Clinic (DMTBC). METHODS: Using univariate and multivariate analysis, we compared treatment completion rates between 4R and 9-month isoniazid (9H) regimens for all pediatric patients treated for LTBI at the DMTBC between 1/1/2006 and 12/31/2015, and assessed the influence of clinical and demographic characteristics on successful completion of the two regimens...

The main aim was to measure the incidence of latent tuberculosis infection (LTBI) and identify risk factors associated with infection. In addition, we determined the number needed to screen (NNS) to identify LTBI and active tuberculosis. We followed 129 prisoners for 2 years following a negative two-step tuberculin skin test (TST). The cumulative incidence of TST conversion over 2 years was 29·5% (38/129), among the new TST converters, nine developed active TB. Among persons with no evidence of LTBI, the NNS to identify a LTBI case was 3·4 and an active TB case was 14·3...

Mycobacterium tuberculosis is the leading cause of death worldwide from a single bacterial pathogen. The World Health Organization estimates that annually 1 million children have tuberculosis (TB) disease and many more harbor a latent form. Accurate estimates are hindered by under-recognition and challenges in diagnosis. To date, an accurate diagnostic test to confirm TB in children does not exist. Treatment is lengthy but outcomes are generally favorable with timely initiation. With the End TB Strategy, there is an urgent need for improved diagnostics and treatment to prevent the unnecessary morbidity and mortality from TB in children...

Tuberculosis (TB) is the most important infectious disease all over the world, with a high morbidity and mortality. Pediatric tuberculosis has been a neglected epidemic, due to the difficulties in assessing its global impact, reduced incidence and lower infectivity compared to adults. In 2015, the WHO reported 1 million cases of paediatric TB and 169,000 deaths. In Europe, the emergence of MDR TB is a major concern, representing 16% of the new diagnosis in Eastern Europe. In 2014, it was estimated that about 219,000 children were infected by MDR-TB-strains in Europe, and 2,120 developed the disease...

Children suffer a huge and often underappreciated burden of disease in tuberculosis (TB) endemic countries. Major hurdles include limited awareness among health care workers, poor integration of TB into maternal and child health approaches, diagnostic difficulties and a lack of child-friendly treatment options. Accurate disease diagnosis is particularly difficult in young and vulnerable children who tend to develop paucibacillary disease and are unable to produce an expectorated sputum sample. In addition, access to chest radiography is problematic in resource-limited settings...

Tuberculosis (TB) remains a major health problem, affecting approximately one-third of the world׳s population. The tubercle bacillus can affect virtually any organ of the human body and if left untreated can lead to severe morbidity and death. Diagnosis of active TB is challenging, especially in children. As a "great imitator," the disease can mimic numerous other pathologies, both clinically and at imaging. Although recognition of active TB is crucial to initiate adequate treatment in a timely fashion, thereby preventing transmission of disease, differentiation of active and quiescent disease is not always straightforward...

Latent tuberculosis infection (LTBI) affects one third to one fourth of the human population and is the reservoir for a significant proportion of emerging active tuberculosis (TB) cases, especially in low incidence countries. The World Health Organization launched in 2015 the END-TB strategy that aims at TB elimination and promotes, for the first time ever, the management of LTBI. The preventive package, basically consisting of testing and treatment for LTBI in groups at high risk of reactivation, is a mainstay of the first pillar of the strategy, alongside prompt diagnosis and early treatment of both drug-susceptible and drug-resistant TB disease...
