INTRODUCTION: Elevated levels of indoor air pollutants may cause cardiopulmonary disease such as lower respiratory infection, chronic obstructive lung disease and lung cancer, but the association with tuberculosis (TB) is unclear. So far the risk estimates of TB infection or/and disease due to indoor air pollution (IAP) exposure are based on self-reported exposures rather than direct measurements of IAP, and these exposures have not been validated. OBJECTIVE: The aim of this paper was to characterize and develop predictive models for concentrations of three air pollutants (PM10, NO2 and SO2) in homes of children participating in a childhood TB study...

Drug-resistant tuberculosis (DR-TB) is a growing global health threat and children are especially vulnerable to becoming infected and sick with DR-TB. There is a growing body of evidence on the optimal diagnosis, treatment and prevention of DR-TB in this vulnerable population. Areas covered: A comprehensive review of the literature on DR-TB in children was done using PubMed and Ovid databases up to December 31, 2016. Topic areas covered included diagnosis of DR-TB, treatment of DR-TB-including novel medications and regimens, prevention of DR-TB, community-based care, and stigma/discrimination...

Tuberculosis (TB) is still endemic in many developing countries. Involvement of wrist joint is very rare, and the diagnosis is often missed. We present a case of isolated TB of the wrist, which was confirmed with intraosseous tissue histopathological examination in a 10-year-old boy. Antibacterial chemotherapy during 12 months promoted healing and good outcome.

IFN-γ release assays (IGRAs) often present false-negative or indeterminate results in children with tuberculosis. HIV co-infection may contribute to decreased sensitivity of IGRAs by impairing T-cell IFN-γ expression. Measurement of alternative cytokines in QuantiFERON(®) (QFT) supernatants can circumvent the IFN-γ-dependency and may improve QFT sensitivity. We aimed to identify additional cytokines from QFT supernatants for detection of Mycobacterium tuberculosis infection in children with tuberculosis and HIV co-infection from Ghana...

SETTING: The tuberculin skin test (TST) and interferon-gamma release assays (IGRAs) are used as supportive evidence to diagnose active tuberculosis (TB). Novel IGRAs could improve diagnosis, but data are lacking in young children. DESIGN: Children (age 5 years) with suspected TB were prospectively screened at a tertiary hospital in Pune, India; the children underwent TST, and standard (early secretory antigenic target 6 and culture filtrate protein 10) and enhanced (five additional novel antigens) enzyme-linked immunospot (ELISpot) assays...

A systematic review was conducted to describe the quality and characteristics of prediction models for prevalent pulmonary tuberculosis (PTB) in adults at routine TB care settings. A prediction model was defined as the combination of two or more clinical predictors designed to estimate the probability of having TB. Studies using culture-confirmed PTB as reference standard were included. Models for in-patients, children or specific patient populations were excluded. PubMed, Scopus and the Cochrane Library and abstracts from the International Union Against Tuberculosis and Lung Disease, American Thoracic Society and European Respiratory Society conferences were searched...

Miliary tuberculosis (TB) results from a massive lymphohematogenous dissemination of Mycobacterium tuberculosis bacilli and is characterized by tiny tubercles evident on gross pathology resembling millet seeds in size and appearance. The global HIV/AIDS pandemic and widespread use of immunosuppressive drugs and biologicals have altered the epidemiology of miliary TB. Considered to be predominantly a disease of infants and children in the pre-antibiotic era, miliary TB is increasingly being encountered in adults as well...

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...

BACKGROUND: Minors with a stated age <18 years unaccompanied by a responsible adult form an increasing part of refugees to Europe. They are older than other asylum-seeking children and many come from countries with a high tuberculosis (TB) incidence. During the 2015 refugee crisis, 35,369 of 162,877 refugees (22%) seeking asylum in Sweden were unaccompanied minors, which gave us the opportunity to study their burden of TB infection and disease. METHODS: Of the unaccompanied minors seeking asylum in Sweden during 2015, 2936 (8...

BACKGROUND: Timely and accurate identification of people with latent tuberculosis infection (LTBI) is important for controlling Mycobacterium tuberculosis (TB). There is no gold standard for diagnosis of LTBI. Screening tests such as interferon gamma release assays (IGRAs) and tuberculin skin test (TST) provide indirect and imperfect information. This systematic review compared two types of IGRAs QuantiFERON®-TB Gold In-Tube test (QFT-GIT) and T-SPOT.TB with TST for identification of LTBI by predicting progression to a diagnosis of active TB in three subgroups: children, immunocompromised people, and those recently arrived from countries with high TB burden...

BACKGROUND: Cambodia is one of the 22 countries with the highest TB burden. While childhood TB is estimated to make up 10-20% of total TB cases in high-burden settings, this proportion ranges from 1.3 to 39.4% throughout Cambodia's provinces, suggesting potential under- and over-diagnosis of childhood TB, subnationally. The proportion of case notifications classified as extrapulmonary TB out of total TB case notifications in children is 87%, greatly exceeding the expected global range of 20-30%...

Lichen scrofulosorum (LS), a tuberculid affecting children and young adults, usually presents with asymptomatic skin-coloured to erythematous follicular and perifollicular papules over the trunk and extremities. An underlying focus of tuberculosis can be detected, but occasionally other mycobacterial infections may be responsible. The eruption is associated with a positive tuberculin test or positive interferon-gamma release assay. Perifollicular granulomas and absence of bacilli are the histopathological characteristics...

INTRODUCTION: Tuberculosis (TB) is a significant cause of morbidity and mortality among children. The vague symptoms, the uncertain diagnostic tests and lack of adequate awareness among families all contributed in masking the actual prevalence of the disease. The objective of this study was to describe the epidemiology of childhood TB in River Nile State (RNS), North Sudan. METHODS: All registered cases of TB aged 15 years and below, at the 13 management units in RNS during 3 years, 2011-2013 were included...

Pneumococcal proteins have been evaluated as genetically-conserved potential vaccine candidates. We have previously demonstrated that a fragment of PspA in fusion with PdT (rPspA-PdT) induced protective immune responses in mice. However, purified proteins have shown poor immunogenicity and often require the combination with strong adjuvants and booster doses. Here, we investigated the use of a Bacillus Calmette-Guérin (BCG) strain, a well-established prophylactic vaccine for tuberculosis with known adjuvant properties, for delivery of the PspA-PdT fusion protein...
