REVIEW
James Gaensbauer, Richard Broadhurst
PURPOSE OF REVIEW: Tuberculosis is leading cause of global morbidity and mortality and a significant proportion of the burden of disease occurs in children. In the past 5 years, a number of innovations have improved the diagnosis and treatment for children with both latent tuberculosis infection and active disease. RECENT FINDINGS: This review discusses three key areas of innovation. First, we assess utilization and performance of interferon-gamma release assays (IGRAs) in different clinical and epidemiologic scenarios...

Chest is the commonest site of involvement by tuberculosis (TB) in children; lungs being the most frequently affected region, followed by nodes, pleura and chest wall. It is difficult to diagnose TB in children due to lack of overt symptoms and difficulty in obtaining samples for microbiological confirmation. Hence various imaging modalities play an important role in diagnostic algorithm as well as in follow-up after treatment. Standardization of chest radiograph reporting in context of clinically suspected TB is the need of the hour so as to suggest a proper diagnosis and avoid over-diagnosis...

INTRODUCTION: Nasal nitric oxide (nNO) is extremely low in individuals with primary ciliary dyskinesia (PCD) and is recommended as part of early workup. We investigated whether tidal breathing sampling for a few seconds was as discriminative between PCD and healthy controls (HC) as conventional tidal breathing sampling (cTB-nNO) for 20-30 s. METHODS: We performed very rapid sampling of tidal breathing (vrTB-nNO) for 2, 4 and 6 s, respectively. Vacuum sampling with applied negative pressure (vrTB-nNOvac ; negative pressure was applied by pinching the sampling tube) for < 2 s resulted in enhanced suction of nasal air during measurement...

Background: Multidrug-resistant tuberculosis (MDR-TB) jeopardizes global TB control. The prevalence and predictors of Rifampicin-resistant (RR) TB, a proxy for MDR-TB, and the treatment outcomes with standard and shortened regimens have not been assessed in post-conflict regions, such as the South Kivu province in the eastern Democratic Republic of the Congo (DRC). We aimed to fill this knowledge gap and to inform the DRC National TB Program. Methods: of adults and children evaluated for pulmonary TB by sputum smear microscopy and Xpert MTB/RIF (Xpert) from February 2012 to June 2017...

Tuberculosis (TB) is a progressive granulomatous infectious disease caused by the gram positive, acid fast bacilli classified under the genus Mycobacterium. Tuberculosis in human is mostly by Mycobacterium tuberculosis and primarily affects lungs causing pulmonary tuberculosis. It can also affect intestine, meninges, bones, joints, lymph nodes, skin and other tissues of the body causing extra-pulmonary tuberculosis. Human TB is transmitted mainly through droplet infection and droplet nuclei. Infection of human with M...

OBJECTIVE: To evaluate utility of Xpert MTB/RIF in bronchoalveolar lavage fluid in children with probable pulmonary tuberculosis. METHODS: Children with probable pulmonary tuberculosis with negative smear and Xpert on induced sputum/gastric aspirate were subjected to bronchoalveolar lavage (BAL) for Xpert assay and mycobacterial liquid culture. Data of children <14 y undergoing bronchoscopy for suspected MDR-TB (n=12) were also analyzed. The sensitivity of Xpert in BAL fluid for diagnosis of probable and confirmed pulmonary tuberculosis was calculated with clinico-radiological diagnosis and culture as gold standards, respectively...

Tuberculosis (TB), once widely prevalent throughout the world, experienced falling incidence rates in early twentieth century in developed nations, even before the introduction of anti-TB drugs, attributed to improved hygiene and living conditions. Active TB may develop following fresh infection or activation of latent tuberculosis infection (LTBI). LTBI is a state of persistent bacterial viability, however, the host stays asymptomatic and there is no evidence of clinically active tuberculosis. Therefore, treatment of all LTBI is considered as one of the ways to control tuberculosis...

Background: Whole-ventricular radiotherapy (WV-RT) followed by a boost to the tumor bed (WV-RT/TB) is recommended for intracranial germ cell tumors (IGCT). As the critical brain areas are mainly in the target volume vicinity, it is unclear if protons indeed substantially spare neurofunctional organs at risk (NOAR). Therefore, a dosimetric comparison study of WV-RT/TB was conducted to assess whether proton or photon radiotherapy achieves better NOAR sparing. Methods: Eleven children with GCT received 24 Gy(RBE) WV-RT and a boost up to 40 Gy(RBE) in 25 fractions of 1...

Background: International guidelines recommend monitoring weight as an indicator of therapeutic response in childhood tuberculosis (TB) disease. This recommendation is based on observations in adults. In the current study, we evaluated the association between weight change and treatment outcome, the accuracy of using weight change to predict regimen efficacy, and whether successfully treated children achieve catch-up weight gain. Methods: We enrolled children treated for drug-susceptible TB disease (group 1) and multidrug-resistant TB disease (group 2) in Peru...

Children suffer a huge and often an unrecognized burden of tuberculosis (TB) in endemic countries like India. Better data have improved the visibility of childhood TB, but the establishment of functional TB prevention and treatment programs for children remains challenging. Barriers to TB prevention include: 1) non-implementation of existing guidelines, 2) perceived inability to rule out active TB with fear of creating drug resistance and 3) limited local guidance on the use of preventive therapy after close contact with drug resistant TB...

BACKGROUND: Confirmatory diagnosis of extra-pulmonary tuberculosis remains a true challenge owing to difficulty in procuring appropriate specimen, inefficient laboratory methods and paucibacillary nature of infection. These obstructions become all the very difficult in pediatric EPTB cases, due to non-specific clinical signs and symptoms, low sensitivity of smear microscopy and culture, lack of awareness among clinicians, etc. AIM OF THE STUDY: The present study aimed to evaluate the diagnostic accuracy of rapid and cost-effective loop-mediated isothermal amplification (LAMP) assay for EPTB diagnosis in children...

Interferon-gamma release assays are increasingly used in children to establish evidence of tuberculosis (TB) infection and to assist in the diagnosis of TB disease. The QuantiFERON-TB Gold In-Tube assay is being phased out in favor of a next-generation test, the QuantiFERON-TB Gold Plus (QFT-Plus) assay. The QFT-Plus assay is designed with two antigen tubes to differentially stimulate CD4+ and CD8+ T cells. The performance of this assay has been documented extensively in adults but has not yet been evaluated in children...

This study characterized the pharmacokinetics of novel 100 mg levofloxacin dispersible tablets in 24 children aged <5 years with household MDR-TB exposure. Data was pooled with previously published data from children (n=109) with MDR-TB receiving adult (250 mg) levofloxacin tablets, using nonlinear mixed-effects modelling. The adult 250 mg tablets had 41% lower bioavailability compared to the novel dispersible tablets, resulting in much higher exposures with the dispersible tablets with the same mg/kg dose...

Approximately 25,000 children develop multidrug-resistant (MDR) tuberculosis (TB) each year, but few of them are diagnosed and appropriately treated for MDR-TB. New diagnostic tools have improved our ability to diagnose children with bacteriologically confirmed TB earlier. However, the majority of childhood TB cases are not bacteriologically confirmed; therefore a high index of suspicion is needed, and taking a detailed history of contact with drug-resistant source cases and previous TB treatment is important to identify presumed MDR-TB cases...

Pediatric tuberculosis (TB) is a significant global health threat and is one of the top ten causes of death in children. There are a number of diagnostic, treatment, and preventive innovations that have been developed in the last decade for TB, however, these are out of reach for many children in the world. Areas covered: A comprehensive review of the literature on TB in children was done using PubMed and Ovid databases from January 1, 1996 up to October 31, 2018. Topic areas covered included diagnosis of TB, treatment of TB (including novel medications and regimens), prevention of DR-TB, and support to achieve the best possible outcomes...
