This document is the result of the deliberations of the Committee on Emerging Pathogens and COVID-19 of the Illustrious Official College of Physicians of Madrid (ICOMEM) regarding the current situation of tuberculosis, particularly in Spain. We have reviewed aspects such as the evolution of its incidence, the populations currently most exposed and the health care circuits for the care of these patients in Spain. We have also discussed latent tuberculosis, the reality of extrapulmonary disease in the XXI century and the means available in daily practice for the diagnosis of both latent and active forms...

Tuberculosis (TB) is a communicable disease that is a major cause of ill health and one of the leading causes of death worldwide. Children act as reservoirs of infection out of which future cases develop. Without the successful detection and treatment of TB infection and disease in children, elimination strategies for TB will be ineffective. India has a severe problem with TB in children, which accounts for around 31% of the global pediatric TB load. However, over the past 10 y, children have consistently made up 6-7% of all patients treated yearly under the National Tuberculosis Elimination Programme (NTEP)...

OBJECTIVES: To find out the diagnostic accuracy of stool Cartridge-based nucleic acid amplification test (CBNAAT) as an alternate method as compared to CBNAAT in gastric aspirate (GA) samples in pediatric tuberculosis (TB). METHODS: This cross-sectional study was performed at Department of Pediatrics of a tertiary care hospital. Children aged 0-18 y diagnosed as presumptive tuberculosis were consecutively enrolled. Gastric aspirate and corresponding stool sample was subjected to CBNAAT and its performance was compared in both samples using appropriate statistical tests...

Tuberculosis (TB) is a pulmonary disease with potential extrapulmonary manifestations that is caused by the bacteria Mycobacterium tuberculosis . Despite advancements in treatment, TB remains a worldwide public health concern. TB osteomyelitis accounts for approximately 3-5% of all extrapulmonary TB cases. We present a case of humeral TB osteomyelitis in a 22-month-old female with no pulmonary or systemic symptoms. This case offers insight into the diagnosis and management of TB osteomyelitis. A 22-month-old previously healthy Haitian-American female presented with a one-month history of a palpable mass over the anterolateral aspect of the proximal humerus without overlying erythema or soft tissue swelling...

Nanopore sensing of proteomic biomarkers lacks accuracy due to the ultralow abundance of targets, a wide variety of interferents in clinical samples, and the mismatch between pore and analyte sizes. By converting antigens to DNA probes via click chemistry and quantifying their characteristic signals, we show a nanopore assay with several amplification mechanisms to achieve an attomolar level limit of detection that enables quantitation of the circulating Mycobacterium tuberculosis ( Mtb ) antigen ESAT-6/CFP-10 complex in human serum...

BACKGROUND: Although tuberculosis disease is a leading cause of global childhood mortality, there remain major gaps in diagnosis, treatment and prevention in children, as tuberculosis control programs rely predominantly on presentation of symptomatic children or contact tracing. We assessed the public health impact and cost-effectiveness of age-based routine screening and contact tracing in children in South Africa. METHODS: We used a deterministic mathematical model to evaluate age-based routine screening in 1-year increments from ages 0 to 5, with and without contact tracing and preventive treatment...

Background Mycobacterium is certainly one individual organism contributing to the most deaths of children among the world's lower- and medium-income nations. According to earlier studies, vitamin D insufficiency is one of the risk factors. We undertook this study since very few case-control studies are present. This study aimed to evaluate the role of vitamin D in tuberculosis (TB). Methods This case-control study was carried out in a tertiary care center at Niloufer Hospital over a period of one year and five months...

This study aimed to determine phenotypic and genotypic drug resistance patterns of Mycobacterium tuberculosis strains from children with tuberculosis (TB) in China and Russia, two high-burden countries for multi/extensively-drug resistant (MDR/XDR) TB. Whole-genome sequencing data of M. tuberculosis isolates from China ( n = 137) and Russia ( n = 60) were analyzed for phylogenetic markers and drug-resistance mutations, followed by comparison with phenotypic susceptibility data. The Beijing genotype was detected in 126 Chinese and 50 Russian isolates...

Rifampicin-resistant tuberculosis (RR-TB) involves treatment with many drugs that can prolong the QT interval; this risk may increase when multiple QT-prolonging drugs are used together. We assessed QT interval prolongation in children with RR-TB receiving one or more QT-prolonging drugs. Data were obtained from two prospective observational studies in Cape Town, South Africa. Electrocardiograms were performed before and after drug administration of clofazimine (CFZ), levofloxacin (LFX), moxifloxacin (MFX), bedaquiline (BDQ), and delamanid...

OBJECTIVE: Children are an important demographic group for understanding overall tuberculosis epidemiology, and monitoring of childhood tuberculosis is essential for appropriate prevention. The present study sought to characterize the spatial distribution of childhood tuberculosis notification rates in continental Portugal; identify high-risk areas; and evaluate the association between childhood tuberculosis notification rates and socioeconomic deprivation. METHODS: Using hierarchical Bayesian spatial models, we analyzed the geographic distribution of pediatric tuberculosis notification rates across 278 municipalities between 2016 and 2020 and determined high-risk and low-risk areas...

Context Tuberculosis (TB) is India's major public health problem. The profile of childhood TB in the northeast region of India is still limited. Aim To analyze the clinical, radiological, and bacteriological profiles of children with TB at a tertiary health care facility. Materials and methods A three years retrospective descriptive analysis of children admitted to a tertiary centre with TB before the introduction of cartridge-based nucleic acid amplification test (CBNAAT) for testing. Children below 18 years who were admitted from 2012 to 2014 and were diagnosed with TB were included...

Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are currently two major causes of death among infectious diseases. Active tuberculosis and a history of tuberculosis appear to be associated with an increased risk of COVID-19. This coinfection, named COVID-TB, was never described in previously healthy children. We report three cases of pediatric COVID-TB. We describe three girls affected by tuberculosis, who tested positive for SARS-CoV-2. The first patient is a 5-year-old girl who was hospitalized for recurrent TB lymphadenopathy...

The outbreak of COVID-19 resulted in a decrease in tuberculosis notification rates globally. We compared tuberculosis incidence rates and disease severity in children seen in our centre prior and during COVID-19 pandemic.We performed a cohort study enrolling children aged under 18 years who received a diagnosis of tuberculosis (January 1st, 2010-December 31st, 2021) at our Pediatric Infectious Diseases Unit. Disease severity was evaluated based on: the classification proposed by Wiseman et al., smear positivity, presence of symptoms at presentation, lung cavitation, extrapulmonary disease, respiratory failure and need for intensive care support...

Pediatric tuberculosis is a major cause of mortality and morbidity in children due to high transmission, poor diagnostic tools, and various respiratory diseases mimicking TB. Identifying risk factors will provide evidence for clinicians to strongly relate their diagnosis to the associated pathology. Studies were retrieved from PubMed, Embase, and Google Scholar, systematically reviewed, and meta-analyzed for various risk factors and their association with pediatric TB. Meta-analysis depicted that four out of eleven risk factors were significant-contact with known TB cases (OR 6...

Rapid, cost-effective, and sensitive diagnostic assays are essential for global tuberculosis (TB) control, especially in high TB burden, resource-limited settings. The current study was designed to evaluate diagnostic accuracy of Truenat MTB-Rif Dx (MolBio) in children less than 18 years of age, with symptoms suggestive of TB. Gastric aspirate, induced sputum, and broncho-alveolar lavage samples were subjected simultaneously to AFB-smear, GeneXpert MTB/RIF, liquid culture (MGIT-960) and Truenat MTB-Rif Dx...

BACKGROUND: The culture of gastric aspirate (GA) has been used for bacteriological confirmation of pulmonary tuberculosis in children and patients who are unable to expectorate. Sodium bicarbonate neutralization of gastric aspirates is commonly recommended to increase culture positivity. We aim to study Mycobacterium tuberculosis (MTB) culture positivity of GA collected from confirmed case of pulmonary tuberculosis after storing it at different temperature, pH & time. METHODS: GA specimens from 865 patients of either sex predominately non-expectorating children/adults with suspected pulmonary TB were collected...

In India, children do not get diagnosed with tuberculosis (TB) for reasons such as lack of screening modality at the health-care settings, inadequate sputum sample, and low detection rate. This study aims to assess various modalities for diagnosis of pediatric TB and their cost-effectiveness. Cost-effectiveness was found for various diagnostic modalities for TB diagnosis in children of India below 15 years of age. TrueNat MTB was the intervention being compared to GeneXpert MTB and sputum microscopy. Evidence pertinent to effectiveness and cost per test, and health benefits in terms of disability adjusted life years were researched and documented...

Tuberculosis (TB) remains a global health problem and is the second leading cause of death from a single infectious agent, behind the novel coronavirus disease of 2019. Children are amongst the most vulnerable groups affected by TB, and imaging manifestations are different in children when compared to adults. TB primarily involves the lungs and mediastinal lymph nodes. Clinical history, physical examination, laboratory examinations and various medical imaging tools are combined to establish the diagnosis. Even though chest radiography is the accepted initial radiological imaging modality for the evaluation of children with TB, this paper, the first of two parts, aims to discuss the advantages and limitations of the various medical imaging modalities and to provide recommendations on which is most appropriate for the initial diagnosis and assessment of possible complications of pulmonary TB in children...
