Appiah MA, Gohoho M, Adzaklo EE, Gone GDK, Aniaku JK, Asamoah PE, Gyapong JO, Kyeremateng E, Tinkorang E. Spatial distribution of paediatric tuberculosis and factors associated with adverse treatment outcomes in Ashanti Region, Ghana: a retrospective analysis. BMC Pediatr 2025; 25:418. [PMID: 40413450 DOI: 10.1186/s12887-025-05704-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 04/21/2025] [Indexed: 05/27/2025] Open
Abstract
BACKGROUND Paediatric tuberculosis (TB) is a major public health concern, contributing significantly to global child morbidity and mortality. In Ghana, there is a scarcity of reports on paediatric TB, and this poses a challenge in effectively monitoring progress in TB control within this age group. This study thus examined the spatial distribution of paediatric TB cases, treatment outcomes, and factors influencing adverse treatment outcomes in the Ashanti Region of Ghana. METHODS This was a retrospective cross-sectional study of paediatric TB cases registered from 2016 to 2020 in 11 randomly selected districts in the Ashanti Region of Ghana. Data were extracted from each district's health facility TB register into a Microsoft Excel spreadsheet. Statistical analysis was performed using Stata version 15.0. Case notification rates (CNR) and treatment outcomes were examined and compared using ArcMap 10.4. Multivariate logistic regression analysis was used to assess the predictors of adverse treatment outcomes. P-values ≤ 0.05 were considered statistically significant at a 95% Confidence Interval. RESULTS A total of 6,180 TB patients were registered for treatment in the 11 selected districts, of which 255 (4.1%) were children. Among the children, the cases were slightly more common among males (52.2%) than females (47.8%). Over the five-year period, a gradually declining trend of CNR for all forms of TB was observed, with an overall CNR of 4.9 cases per 100,000 children. A wide variation of CNR was observed among the districts, ranging from 0.2 to 35.5 cases per 100,000 children. Two hundred and six (80.8%) children were successfully treated, while 49 (19.2%) experienced adverse treatment outcomes, including lost to follow-up 9 (3.5%), deaths 25 (9.8%), and not evaluated 15 (5.9%). Co-infection with HIV (AOR: 2.71; 95% CI: 1.21-6.07, p = 0.015) was a significant predictor of adverse TB treatment outcome. CONCLUSION The overall paediatric TB CNR was low. The treatment success rate fell below the World Health Organization's 90% End TB target, and the case fatality rate is concerning. HIV co-infection contributed to adverse treatment outcomes. Thus, it is recommended that the National Tuberculosis Control Programme (NTP) establish a learning platform where districts with high paediatric TB notification rates share their best practices to encourage others to learn to increase the detection of paediatric TB. Additionally, the NTP should train community health workers to conduct stigma-sensitive integrated home visits for TB/HIV co-infected children to mitigate potential adverse treatment outcomes.

Lung India 2025; 42:199-203. [PMID: 40296390 PMCID: PMC12097665 DOI: 10.4103/lungindia.lungindia_288_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Revised: 11/15/2024] [Accepted: 12/13/2024] [Indexed: 04/30/2025] Open
Abstract
BACKGROUND Mediastinal Tuberculosis (TB), although a common presentation of TB in children, has a very low rate of microbiological confirmation. This is because of the difficulty in acquiring appropriate tissue samples for microbiological confirmation. Endobronchial ultrasound (EBUS) and esophageal ultrasound with a bronchoscope (EUS-B) offer a safe, effective, and minimally invasive modality of sampling in these children. We present our institutional experience on EBUS/EUSB and the various ancillary investigations for mediastinal TB. METHODS This is a single-center retrospective study among children who underwent EBUS/EUS-B for a mediastinal nodal lesion. The primary objective of the study was to analyze the diagnostic accuracy of histopathology and various microbiological investigations, through EBUS/EUS-B guided TBNA, in the diagnosis of mediastinal TB. The secondary objective was to ascertain the safety of EBUS/EUS-B. RESULTS A total of 50 children underwent EBUS/EUS-B at our center, of those 26 (17 girls, mean age 11.7 years) were diagnosed with mediastinal TB. Fever was the most common presenting symptom (85%) and only seven children (26%) had a concomitant pulmonary involvement. The diagnostic performance of various investigations was as follows: Acid-fast bacilli (AFB) smear (sensitivity - 86.6%, specificity - 82.9%, NPV-93.5%, PPV - 68.4%), Xpert Ultra (sensitivity -100%, specificity - 68.5%, NPV - 100%, PPV - 57.7%), and cytology (sensitivity - 100%, specificity - 82.9%, NPV - 100%, PPV - 71.4%). A microbiological confirmation was attained in 81% of the children. There were no major complications in any of the procedures. CONCLUSION EBUS/EUSB is an effective and safe investigation for the diagnosis of mediastinal TB in children.

Abstract
OBJECTIVES To estimate the sensitivity and specificity of childhood pulmonary tuberculosis (CPTB) diagnostic tests, including Xpert MTB/RIF and alternative samples such as nasopharyngeal aspirate and stool. We used latent class analysis to overcome the lack of reference standards. METHODS We included 1165 children suspected of having CPTB in a prospective cohort study conducted in the Ivory Coast, Madagascar, and Cameroon. We used Bayesian latent class analysis to evaluate the performance of multiple diagnostic tests for CPTB: smear microscopy, mycobacterial culture, and Xpert carried out on different types of samples (sputum after 10 years of age, gastric aspirate before 10 years of age, nasopharyngeal aspirate, and stool), tuberculin skin test, and chest X-ray. RESULTS Median age was 3.5 years (95% credible interval [1.3-8.2]). Smear microscopy was highly specific in all types of samples but lacked sensitivity (sputum 31%; 95% credible interval [18-46]), gastric aspirate 36% [27-45], nasopharyngeal aspirate 24% [17-32], and stool 24% [17-32]). Culture sensitivity was slightly higher in gastric (75% [65-83]) than in nasopharyngeal aspirate (64% [54-72]). Xpert sensitivity was similar in gastric (69% [59-78]) and nasopharyngeal aspirate (66% [57-74]) but lower in sputum (58% [43-74]) and stools (53% [44-62]). Xpert was highly specific in all respiratory samples (sputum 96% [96-100], gastric aspirate 100% [99-100], and nasopharyngeal aspirate 100% [99-100]). DISCUSSION The Xpert performed on the nasopharyngeal aspirate shows similar accuracy to the culture. It was also similar to that in gastric aspirate. It highlights an interesting CPTB diagnostic combination.

[PMID: 39934644 DOI: 10.1038/s41390-025-03917-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 11/25/2024] [Accepted: 12/12/2024] [Indexed: 02/13/2025]
Abstract
OBJECTIVES Multidrug-resistant tuberculosis (MDR-TB) has become a major global public health issue, which has worsened over time owing to changes in disease-related trends. This study aimed to determine global trends in MDR-TB among children and adolescents for strategic health planning. METHODS A secondary analysis was performed on MDR-TB burden among children and adolescents (<20 years) at the global, regional, and national levels based on sociodemographic index (SDI) quintiles from 1990 to 2019, using the Global Burden of Disease (GBD) 2019 database. RESULTS In 2019, 67,710.82 (95% uncertainty interval [UI]: 38,823.61 to 110,582.03) incidents of MDR-TB were reported among children and adolescents aged <20 years worldwide. The global incidence rate has increased from 1990 to 2019, with the estimated annual percentage change (EAPC) at 4.15% (95% UI: 1.10-12.19%), particularly in low- and low-middle SDI regions. The top three highest incidence rates were observed in Southern sub-Saharan Africa, Eastern Europe, and South Asia. The mortality and disability-adjusted life years (DALYs) rates (0.62 [95% UI: 0.28-1.14] and 55.19 [95% UI: 25.24-100.74] cases per 100,000, respectively) were higher among children aged <5 years than those in older age groups in 2019. CONCLUSION The global burden of MDR-TB among children and adolescents has increased from 1990 to 2019, particularly in regions with lower SDI. Extensive collaborative research and interventions are needed to mitigate this disease burden to secure the health of our future generation. IMPACT MDR-TB disease burden in children and adolescents using GBD 2019 database was analyzed. In total, 67710.82 MDR-TB cases were identified in children and adolescents in 2019. Global MDR-TB burden in children and adolescents has risen over the past 30 years. MDR-TB disease burden is negatively correlated with the sociodemographic index. MDR-TB disease burden varies across countries and age groups.

Abstract
OBJECTIVES Pediatric tuberculosis (TB) diagnosis is complicated by challenges in obtaining invasive respiratory specimens that frequently contain few Mycobacterium tuberculosis (Mtb) bacilli. We report the diagnostic performance of an Mtb antigen-derived peptide (MAP-TB) assay and its ability to monitor TB treatment response. METHODS Study cohorts enrolled children who presented with presumptive TB at two hospitals in South Africa from 2012 to 2017 (157 children aged <13 years) and at community-based clinics in the Dominican Republic from 2019 to 2023 (101 children aged <18 years). Children were evaluated for TB at enrollment and six months post-enrollment and assigned confirmed, unconfirmed, or unlikely TB diagnoses using the 2015 NIH diagnostic criteria for pediatric TB. MAP-TB assay performance was evaluated using serum collected at baseline and at regular intervals post-enrollment following STARD guidelines. RESULTS MAP-TB sensitivity for confirmed and unconfirmed TB was comparable to culture and Xpert sensitivity for confirmed TB, but MAP-TB specificity revealed age-dependence, decreasing from 98·1% to 78·4%, when including children aged <1 year. MAP-TB values decreased by six months post-treatment initiation in children with symptom improvement. CONCLUSIONS Serum MAP-TB results can effectively diagnose pediatric TB, including unconfirmed and extrapulmonary TB missed by current methods, and correspond to effective treatment.

Pharmacokinetic Analysis of an Isoniazid Suspension Among Spanish Children Under 6 Years of Age. Antibiotics (Basel) 2025; 14:74. [PMID: 39858360 PMCID: PMC11762149 DOI: 10.3390/antibiotics14010074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2024] [Revised: 01/01/2025] [Accepted: 01/07/2025] [Indexed: 01/27/2025] Open
Abstract
Background: Isoniazid (INH) remains a first-line drug for the treatment of tuberculosis (TB) in young children. In 2010, the WHO recommended an increase in the daily dose of INH up to 10 (7-15) mg/kg. Currently, there are no INH suspensions available in Europe. Methods: We aimed to characterize the pharmacokinetics of a licensed INH suspension (10 mg/mL, Pharmascience Inc., Montreal, QC, Canada) in children receiving INH daily at 10 mg/kg in a single-center, open-label, non-randomized, phase IIa clinical trial (EudraCT Number: 2016-002000-31) in Barcelona (Spain). Samples were analyzed using a validated UPLC-UV assay. The N-acetyltransferase 2 gene was examined to determine the acetylation status. A non-compartmental pharmacokinetic analysis was conducted. Results: Twenty-four patients (12 females) were included (primary chemoprophylaxis, n = 12; TB treatment, n = 9; and TB infection preventive treatment, n = 3). The acetylator statuses were homozygous fast (n = 3), heterozygous intermediate (n = 18), and homozygous slow (n = 2; unavailable in one patient). The INH median (IQR) Cmax and AUC0-24h values were 6.1 (4.5-8.2) mg/L and 23.0 (11.2-35.4) h∙mg/L; adult targets (>3 mg/L and 11.6-26.3 h∙mg/L) were not achieved in three and six cases, respectively. Gender, age at assessment (<2 or >2 years), and INH monotherapy (vs. combined TB treatment) had no impact on pharmacokinetic parameters. Significant differences in Cmax (p = 0.030) and AUC0-24h (p = 0.011) values were observed based on acetylator status. Treatment was well tolerated, and no severe adverse events were observed; three patients developed asymptomatic mildly elevated alanine aminotransferase levels. Conclusions: In infants and children receiving a daily INH suspension at 10 mg/kg, no safety concerns were raised, and the target adult levels were reached in the majority of patients.

Abstract
BACKGROUND Recently, face mask sampling (FMS) confirmed detection of Mycobacterium tuberculosis DNA from exhaled breath in adults with tuberculosis. To date, no study has evaluated the use of FMS to detect pulmonary tuberculosis in children. We developed a method for FMS of M. tuberculosis-specific DNA in children and performed a clinical exploration to assess feasibility in children. METHODS Face masks were spiked, analyzed on GeneXpert-Ultra, quantitative polymerase chain reaction, and targeted next-generation sequencing. Children with pulmonary tuberculosis were asked to wear 3 modified FFP2 masks for 30 minutes as part of an exploratory clinical study. RESULTS Experiments with H37Ra M. tuberculosis strain showed a limit of 95% detection of 3.75 colony-forming units (95% confidence interval, 4.85-3.11) on GeneXpert-Ultra. Ten children with pulmonary tuberculosis participated in the clinical study. M. tuberculosis-specific DNA was detected on none of the face masks. CONCLUSIONS Pediatric FMS has a low limit of detection for M. tuberculosis-specific DNA in vitro. However, M. tuberculosis DNA was not detected in any of 30 masks worn by children with pulmonary tuberculosis. This suggests that FMS in this form may not be more effective for detecting M. tuberculosis in children with tuberculosis than existing methods.

Abstract
Tuberculosis (TB) continues to pose a significant health challenge globally and in Portugal. Diagnostic challenges persist, especially in infants, where TB often presents with atypical symptoms. A previously healthy three-month-old male infant from Vila Nova de Famalicão, Portugal, was admitted with cough, rhinorrhea, respiratory distress, and high-grade fever. After chest radiography and blood tests, he was treated with ampicillin for community-acquired pneumonia (CAP). Initial antibiotic therapy proved ineffective, and subsequent imaging showed necrotizing pneumonia. Thoracic computed tomography and bronchoscopy revealed a significant consolidation with cavitation and lymphatic involvement, as well as extrinsic compression of the right main bronchus. Gastric aspirates (GA) and bronchoalveolar lavage (BAL) washings grew Mycobacterium tuberculosis. Treatment eventually with antituberculosis drugs and prednisolone resulted in clinical and radiological improvement. Subsequent immunological evaluations were normal.

Abstract
Background There have been no detailed descriptions of infants born to mothers treated for drug resistant TB in pregnancy. Critical case history assessment is important to identify risks and guide clinical practice. Methods In a cohort of pregnant women with multidrug or rifampicin resistant (MDR/RR)-TB enrolled between 1 January 2013 and 31 December 2022, we followed mother-infant pairs until the infant was 12 months old. We performed critical case history assessments to explore potential mechanisms of Mycobacterium tuberculosis transmission to the infant, and to describe the clinical presentation and disease trajectories observed in infants diagnosed with TB. Findings Among 101 mother-infant pairs, 23 (23%) included infants diagnosed with TB disease; 16 were clinically diagnosed and seven had microbiological confirmation (five MDR/RR-TB, two drug-susceptible TB). A positive maternal sputum culture at the time of delivery was significantly associated with infant TB risk (p = 0.023). Of the 12 infants diagnosed with TB in the first three months of life, seven (58%) of the mothers were culture positive at delivery; of whom four reported poor TB treatment adherence. However, health system failures, including failing to diagnose and treat maternal MDR/RR-TB, inadequate screening of newborns at birth, not providing appropriate TB preventive therapy (TPT), and M. tuberculosis transmission from non-maternal sources also contributed to TB development in infants. Interpretation Infants born to mothers with MDR/RR-TB are at greatest risk if maternal adherence to MDR/RR-TB treatment or antiretroviral therapy (ART) is sub-optimal. In a high TB incidence setting, infants are also at risk of non-maternal household and community transmission. Ensuring maternal TB diagnosis and appropriate treatment, together with adequate TB screening and prevention in all babies born to mothers or households with TB will minimise the risk of infant TB disease development.

Comparative analysis of pediatric pulmonary and extrapulmonary tuberculosis: A single-center retrospective cohort study in Syria. Heliyon 2024; 10:e36779. [PMID: 39263060 PMCID: PMC11387373 DOI: 10.1016/j.heliyon.2024.e36779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 08/21/2024] [Accepted: 08/22/2024] [Indexed: 09/13/2024] Open
Abstract
Background Tuberculosis (TB) is a global public health challenge, contributing significantly to morbidity and mortality worldwide. This research aims to investigate the epidemiology, clinical characteristics, diagnostic methods, and early mortality rate among pediatric patients with pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) who were admitted to a hospital in Syria. Methods This retrospective cohort study was conducted at the University Children's Hospital in Syria, involving pediatric patients diagnosed with TB between January 2013 and January 2023. Data were collected from medical records and encompassed socio-demographic characteristics, diagnostic methods, clinical presentation, chest radiography findings, and patient outcomes. Statistical analysis was performed using SPSS version 25. Results A total of 129 patients were included in the study, with 26.4 % diagnosed with PTB and 73.6 % with EPTB. The most common types of EPTB were lymphatic (25.6 %) and gastrointestinal (17.1 %). Patients with PTB and EPTB did not differ significantly in terms of age, weight, or gender. Significant cough was more common in PTB cases (67.6 %), while lymphadenopathy was more prevalent in EPTB cases (48.4 %). Chest X-ray abnormalities were found in 58.1 % of patients, with PTB patients more likely to have abnormal findings (97.1 %). Microbiological confirmation was higher in PTB cases (76.5 %) compared to EPTB cases (25.3 %). The overall mortality rate was 14 %, with higher mortality observed in patients with EPTB (16.8 %), particularly in cases of TB meningitis. Conclusion Our study highlights the epidemiological challenges of TB among hospitalized children, with a focus on the complexities of diagnosing and managing EPTB. We emphasize the urgent need for enhanced diagnostic and management strategies, particularly in conflict zones like Syria, where TB control efforts face significant obstacles. Prompt solutions are imperative to improve outcomes, given the high occurrence of EPTB and its associated mortality rates. Clinical recommendations stress the need for comprehensive contact histories and awareness of varied clinical presentations in pediatric TB diagnosis.

Isoniazid preventive therapy during infancy does not adversely affect growth among HIV-exposed uninfected children: Secondary analysis of data from a randomized controlled trial. PLoS One 2024; 19:e0293708. [PMID: 39150949 PMCID: PMC11329125 DOI: 10.1371/journal.pone.0293708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 04/08/2024] [Indexed: 08/18/2024] Open
Abstract
BACKGROUND Isoniazid preventive therapy (IPT) decreases risk of tuberculosis (TB) disease; impact on long-term infant growth is unknown. In a recent randomized trial (RCT), we assessed IPT effects on infant growth without known TB exposure. METHODS The infant TB Infection Prevention Study (iTIPS) trial was a non-blinded RCT among HIV-exposed uninfected (HEU) infants in Kenya. Inclusion criteria included age 6-10 weeks, birthweight ≥2.5 kg, and gestation ≥37 weeks. Infants in the IPT arm received 10 mg/kg isoniazid daily for 12 months, while the control trial received no intervention; post-trial observational follow-up continued through 24 months of age. We used intent-to-treat linear mixed-effects models to compare growth rates (weight-for-age z-score [WAZ] and height-for-age z-score [HAZ]) between trial arms. RESULTS Among 298 infants, 150 were randomized to IPT, 47.6% were females, median birthweight was 3.4 kg (interquartile range [IQR] 3.0-3.7), and 98.3% were breastfed. During the 12-month intervention period and 12-month post-RCT follow-up, WAZ and HAZ declined significantly in all children, with more HAZ decline in male infants. There were no growth differences between trial arms, including in sex-stratified analyses. In longitudinal linear analysis, mean WAZ (β = 0.04 [95% CI:-0.14, 0.22]), HAZ (β = 0.14 [95% CI:-0.06, 0.34]), and WHZ [β = -0.07 [95% CI:-0.26, 0.11]) z-scores were similar between arms as were WAZ and HAZ growth trajectories. Infants randomized to IPT had higher monthly WHZ increase (β to 24 months 0.02 [95% CI:0.01, 0.04]) than the no-IPT arm. CONCLUSION IPT administered to HEU infants did not significantly impact growth outcomes in the first two years of life.

Abstract
Background Analyzing the epidemiology and clinical manifestations of pediatric tuberculosis in endemic regions is crucial to meet the goal of ending tuberculosis. The objective was to assess the various clinical scenarios of tuberculosis in a large pediatric cohort in Mexico. Methods This retrospective study from a pediatric referral center in Mexico included patients diagnosed with tuberculosis from 2012 to 2021. We analyzed clinical data and diagnostic study results, including demographic characteristics, underlying medical conditions, BCG vaccination, clinical presentation, imaging findings, microbiologic data, treatment, and clinical outcomes. Basic descriptive statistics and Chi-squared analysis were performed to summarize the metadata of pediatric patients with different clinical presentations of tuberculosis and evaluate their association with mortality, respectively. Results A total of 100 patients were included with a mean age of 7.76 years ± 1.49 years. The most prevalent clinical presentation was pulmonary tuberculosis (n = 51). Only 51 patients were immunized with Bacillus Calmette-Guérin vaccine. The most commons symptoms were fever, cough and weight loss. Among patients with meningeal tuberculosis (n = 14), the most common clinical signs were seizures, fever, and vomiting. Cure was achieved in 52 patients, 12 patients died, and 36 continue in treatment. Clinical presentation of tuberculosis (p-value = 0.009) and immunodeficiency (p-value = 0.015) were significantly associated with mortality. Conclusions Increasing the visibility of tuberculosis is imperative to end this disease. We report relevant clinical data of a large pediatric tuberculosis cohort, stratified by the different forms of disease. A high index of suspicion of tuberculosis is required for a timely diagnosis and treatment initiation, particularly among immunocompromised individuals, in whom mortality is higher.

Abstract
BACKGROUND The outbreak of COVID-19 has caused a setback to the gains achieved in tuberculosis (TB) control by impairing TB diagnosis, delaying treatment initiation and aggravating TB deaths. This study explored the effect of COVID-19 on paediatric TB services provided through the Catalysing Paediatric TB Innovations (CaP-TB) project among caregivers of children receiving TB services and healthcare workers (HCWs) providing TB services in Cameroon and Kenya. METHODS From March to September 2021, in-depth interviews (44) were conducted with caregivers whose children under 5 years had gone through TB services and programme managers (10) overseeing the CaP-TB project. Focus group discussions were conducted with HCWs (07) and community health workers (04) supporting TB care services. Transcripts were coded and analysed by using MAXQDA V.12. RESULTS The COVID-19 pandemic has caused fear and anxiety among HCWs and caregivers. This fear was motivated by stigma related to COVID-19 and affected the ability to screen patients for TB due to the similarity of symptoms with COVID-19. The health-seeking behaviour of patients was affected, as many caregivers avoided hospitals and those accessing the facilities concealed their sickness due to fear of testing positive or being vaccinated. In addition, COVID-19 mitigation strategies implemented by both government and health facilities to curb the spread of the virus limited patient access to paediatric healthcare services. These included temporary closure of health facilities due to COVID-19 infections among staff, transfer of services to other spaces, spacing out patient appointments and reduced time spent with patients. CONCLUSIONS The outbreak of COVID-19 has induced fear and stigma that affected patients' health-seeking behaviour and provider attitudes towards paediatric TB service delivery. In addition, facility and governmental measures put in place to mitigate COVID-19 impact negatively affected paediatric service delivery. Training for health personnel, timely provision of personal protective equipments and appropriate communication strategies could help mitigate COVID-19 impact on paediatric TB service delivery.

Abstract
Cell-mediated immune response is critical for Mycobacterium tuberculosis (M.tb) control. Understanding of pathophysiology and role played by different cell mediators is essential for vaccine development and better management of patients with M.tb. A complex array of cytokines and chemokines are involved in the immune response against M.tb; however, their relative contribution in protection remains to be further explored. The purpose of this review is to summarize the current understanding regarding the cytokine and chemokine profiles in M.tb infection in order to assist research in the field to pursue new direction in prevention and control. We have also summarized recent findings on vaccine trials that have been developed and or are under trials that are targeting these molecules.

Abstract
Background Tuberculosis remains a global health threat, and the World Health Organization reports a limited reduction in disease incidence rates, including both new and relapse cases. Therefore, studies targeting tuberculosis transmission chains and recurrent episodes are crucial for developing the most effective control measures. Herein, multiple tuberculosis clusters were retrospectively investigated by integrating patients' epidemiological and clinical information with median-joining networks recreated based on whole genome sequencing (WGS) data of Mycobacterium tuberculosis isolates. Methods Epidemiologically linked tuberculosis patient clusters were identified during the source case investigation for pediatric tuberculosis patients. Only M. tuberculosis isolate DNA samples with previously determined spoligotypes identical within clusters were subjected to WGS and further median-joining network recreation. Relevant clinical and epidemiological data were obtained from patient medical records. Results We investigated 18 clusters comprising 100 active tuberculosis patients 29 of whom were children at the time of diagnosis; nine patients experienced recurrent episodes. M. tuberculosis isolates of studied clusters belonged to Lineages 2 (sub-lineage 2.2.1) and 4 (sub-lineages 4.3.3, 4.1.2.1, 4.8, and 4.2.1), while sub-lineage 4.3.3 (LAM) was the most abundant. Isolates of six clusters were drug-resistant. Within clusters, the maximum genetic distance between closely related isolates was only 5-11 single nucleotide variants (SNVs). Recreated median-joining networks, integrated with patients' diagnoses, specimen collection dates, sputum smear microscopy, and epidemiological investigation results indicated transmission directions within clusters and long periods of latent infection. It also facilitated the identification of potential infection sources for pediatric patients and recurrent active tuberculosis episodes refuting the reactivation possibility despite the small genetic distance of ≤5 SNVs between isolates. However, unidentified active tuberculosis cases within the cluster, the variable mycobacterial mutation rate in dormant and active states, and low M. tuberculosis genetic variability inferred precise transmission chain delineation. In some cases, heterozygous SNVs with an allelic frequency of 10-73% proved valuable in identifying direct transmission events. Conclusion The complex approach of integrating tuberculosis cluster WGS-data-based median-joining networks with relevant epidemiological and clinical data proved valuable in delineating epidemiologically linked patient transmission chains and deciphering causes of recurrent tuberculosis episodes within clusters.

Abstract
Infants born to mothers with tuberculosis disease are at increased risk of developing tuberculosis disease themselves. We reviewed published studies and guidelines on the management of these infants to inform the development of a consensus practice guideline. We searched MEDLINE, CINAHL, and Cochrane Library from database inception to Dec 1, 2022, for original studies reporting the management and outcome of infants born to mothers with tuberculosis. Of the 521 published papers identified, only three met inclusion criteria and no evidence-based conclusions could be drawn from these studies, given their narrow scope, variable aims, descriptive nature, inconsistent data collection, and high attrition rates. We also assessed a collection of national and international guidelines to inform a consensus practice guideline developed by an international panel of experts from different epidemiological contexts. The 16 guidelines reviewed had consistent features to inform the expert consultation process. Two management algorithms were developed-one for infants born to mothers considered potentially infectious at the time of delivery and another for mothers not considered infectious at the time of delivery-with different guidance for high and low tuberculosis incidence settings. This systematic review and consensus practice guideline should facilitate more consistent clinical management, support the collection of better data, and encourage the development of more studies to improve evidence-based care.

Front Pediatr 2024; 12:1370687. [PMID: 38659699 PMCID: PMC11039875 DOI: 10.3389/fped.2024.1370687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 03/11/2024] [Indexed: 04/26/2024] Open
Abstract
Background It has been reported that differential diagnosis of bacterial or viral pneumonia and tuberculosis (TB) in infants and young children is complex. This could be due to the difficulty in microbiological confirmation in this age group. In this study, we aimed to assess the utility of a real-time multiplex PCR for diagnosis of respiratory pathogens in children with pulmonary TB. Methods A total of 185 respiratory samples [bronchoalveolar lavage (15), gastric aspirates (98), induced sputum (21), and sputum (51)] from children aged 3-12 years, attending tertiary care hospitals, Chennai, India, were included in the study. The samples were processed by N acetyl L cysteine (NALC) NAOH treatment and subjected to microbiological investigations for Mycobacterium tuberculosis (MTB) diagnosis that involved smear microscopy, Xpert® MTB/RIF testing, and liquid culture. In addition, DNA extraction from the processed sputum was carried out and was subjected to a multiplex real-time PCR comprising a panel of bacterial and fungal pathogens. Results Out of the 185 samples tested, a total of 20 samples were positive for MTB by either one or more identification methods (smear, culture, and GeneXpert). Out of these 20 MTB-positive samples, 15 were positive for one or more bacterial or fungal pathogens, with different cycle threshold values. Among patients with negative MTB test results (n = 165), 145 (87%) tested positive for one or more than one bacterial or fungal pathogens. Conclusion The results suggest that tuberculosis could coexist with other respiratory pathogens causing pneumonia. However, a large-scale prospective study from different geographical settings that uses such simultaneous detection methods for diagnosis of childhood tuberculosis and pneumonia will help in assessing the utility of these tests in rapid diagnosis of respiratory infections.

Tuberculosis treatment monitoring tests during routine practice: study design guidance. Clin Microbiol Infect 2024; 30:481-488.

Abstract
SCOPE The current tools for tuberculosis (TB) treatment monitoring, smear microscopy and culture, cannot accurately predict poor treatment outcomes. Research into new TB treatment monitoring tools (TMTs) is growing, but data are unreliable. In this article, we aim to provide guidance for studies investigating and evaluating TB TMT for use during routine clinical care. Here, a TB TMT would guide treatment during the course of therapy, rather than testing for a cure at the regimen's end. This article does not cover the use of TB TMTs as surrogate endpoints in the clinical trial context. METHODS Guidelines were initially informed by experiences during a systematic review of TB TMTs. Subsequently, a small content expert group was consulted for feedback on initial recommendations. After revision, feedback from substantive experts across sectors was sought. QUESTIONS ADDRESSED BY THE GUIDELINE AND RECOMMENDATIONS The proposed considerations and recommendations for studies evaluating TB TMTs for use during the treatment in routine clinical care fall into eight domains. We provide specific recommendations regarding study design and recruitment, outcome definitions, reference standards, participant follow-up, clinical setting, study population, treatment regimen reporting, and index tests and data presentation. Overall, TB TMTs should be evaluated in a manner similar to diagnostic tests, but TB TMT accuracy must be assessed at multiple timepoints throughout the treatment course, and TB TMTs should be evaluated in study populations who have already received a diagnosis of TB. Study design and outcome definitions must be aligned with the developmental phase of the TB TMT under evaluation. There is no reference standard for TB treatment response, so different reference standards and comparator tests have been proposed, the selection of which will vary depending on the developmental phase of the TMT under assessment. The use of comparator tests can assist in generating evidence. Clarity is required when reporting of timepoints, TMT read-outs, and analysis results. Implementing these recommendations will lead to higher quality TB TMT studies that will allow data to be meaningfully compared, thereby facilitating the development of novel tools to guide individual TB therapy and improve treatment outcomes.

Vaccine 2024; 42:2099-2105. [PMID: 38423810 DOI: 10.1016/j.vaccine.2024.02.061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 02/19/2024] [Accepted: 02/21/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND Since 2010, Ireland's Tuberculosis (TB) crude incidence rate (CIR) remains below 10 per 100,000 population defining it as a low TB incidence country. Ireland maintained a universal BCG vaccination programme until its discontinuation in 2015 due to lack of vaccine supply. This study explores the impact of discontinuing a national universal BCG vaccination programme on the epidemiology of paediatric TB cases. METHODS We retrospectively analysed TB notifications aged 0-6 years old reported to the Irish National TB Surveillance System between 2011 and 2021. Key epidemiological characteristics and temporal trends in TB age specific incidence rates (ASIRs) were compared between 0 and 6 year old cases born during a period of universal BCG vaccination (2007-2015) and 0-6 year old cases born after BCG vaccination ceased (2015-2021). RESULTS No significant temporal trend was detected in the overall 0-6 year old ASIR by notification year during 2011-2021 (IRR:0.95; 0.86-1.1). However, the temporal trend for cases born during universal vaccination showed a significant decline (0.74; CIR: 0.62-0.89) while cases born after BCG vaccination ceased had a non-significant increase (1.2; CIR: 0.73-1.86). A significantly declining temporal trend was detected among cases born in Ireland during universal vaccination (IRR:0.73; 0.62-0.86), but no significant trend was detected in the cases born outside Ireland during universal vaccination (IRR:0.83; 0.53-1.31). No significant trend was detected in cases born after vaccination ceased in either cases born in Ireland (IRR:1.0; 0.60-1.65) or those born outside Ireland (IRR:0.64; 0.29-1.40). CONCLUSIONS Universal BCG cessation has not yet directly impacted on TB cases among 0-6 year olds in Ireland. However, interruption of the previously declining temporal trend in this cohort during universal vaccination may be an early warning of a future increase. Paediatric TB cases remain an important cohort for timely surveillance to monitor trends in this primarily unvaccinated cohort to evaluate the long-term effects.

Abstract
In 2022, an estimated 1.25 million children <15 years of age developed tuberculosis (TB) worldwide, but >50% remained undiagnosed or unreported. WHO recently recommended integrated and decentralized models of care as an approach to improve access to TB services for children, but evidence remains limited. The Catalyzing Paediatric TB Innovation project (CaP-TB) implemented a multi-pronged intervention to improve TB case finding in children in nine sub-Saharan African countries. The intervention introduced systematic TB screening in different facility-based child-health entry-points, decentralisation of TB diagnosis and management, improved sample collection with access to Xpert® MTB/RIF or MTB/RIF Ultra testing, and implementation of contact investigation. Pre-intervention records were compared with those during intervention to assess effect on paediatric TB cascade of care. The intervention screened 1 991 401 children <15 years of age for TB across 144 health care facilities. The monthly paediatric TB case detection rate increased significantly during intervention versus pre-intervention (+46.0%, 95% CI 36.2-55.8%; p<0.0001), with variability across countries. The increase was greater in the <5 years old compared to the 5-14 years old (+53.4%, 95% CI 35.2-71.9%; p<0.0001 versus +39.9%, 95% CI 27.6-52.2%; p<0.0001). Relative contribution of lower-tier facilities to total case detection rate increased from 37% (71.8/191.8) pre-intervention to 50% (139.9/280.2) during intervention. The majority (89.5%) of children with TB were identified through facility-based intensified case-finding and primarily accessed care through outpatient and inpatient departments. In this multi-country study implemented under real-life conditions, the implementation of integrated and decentralized interventions increased paediatric TB case detection. The increase was driven by lower-tier facilities that serve as the primary point of healthcare contact for most patients. The effect was greater in children < 5 years compared to 5-14 years old, representing an important achievement as the TB detection gap is higher in this subpopulation. (Study number NCT03948698).

Abstract
BACKGROUND The differentiation between latent tuberculosis infection (LTBI) and tuberculosis (TB) relies on radiological changes. Confirming the diagnosis remains a challenge because typical findings are often missing in children. This study evaluates diagnostic sensitivity, specifity and interobserver agreement on the radiological diagnosis of TB by chest-x-rays in accordance to professional specialization and work experience. METHODS Chest x-rays of 120 children with proven tuberculosis infection were independently evaluated by general radiologists, paediatric radiologists and paediatric pulmonologists. Results were compared to a reference diagnosis created by group of experienced paediatric radiologists and paediatric pulmonologists. Primary endpoints were diagnostic sensitivity and specificity and interobserver variability defined as Krippendorfs alpha of thesel groups compared to the reference diagnosis. RESULTS Of the 120 chest x-rays 33 (27,5%) were diagnosed as TB by the reference standard . Paediatric pulmonologist had the highest diagnostic sensitivity (90%) but were less specific (71%) whereas general radiologist were less sensitive (68%) but more secific (95%). The best diagnostic accuracy was achieved by pediatric radiologists with a diagnostic sensitivity of 77% and specificity 95% respectively. CONCLUSIONS We demonstrated significant interobserver variability and relevant differences in sensitivity and specificity in the radiological diagnosis of TB between the groups. Paediatric radiologists showed the best diagnostic performance. As the diagnosis of pulmonary TB has significant therapeutic consequences for children they should be routinely involved in the diagnostic process.

Abstract
Paediatric tuberculosis can be challenging to diagnose, and various approaches are used in different settings. A retrospective review was conducted on Papua New Guinea (PNG) children with presumptive TB who presented for health care in the Torres Strait Islands, Australia, between 2016 and 2019. We compared diagnostic algorithms including the modified Keith Edwards TB Score, The Union Desk Guide, and the new World Health Organization (WHO) algorithm, with diagnostic practices used in the remote Torres Strait Islands. Of the 66 children with presumptive TB, 7 had bacteriologically confirmed TB. The majority (52%) were under 5 years (median age 61 months), and 45% were malnourished. There was moderate agreement across the diagnostic methods (K = 0.34; 95% CI 0.23-0.46), with the highest concordance observed between The Union Desk Guide and the WHO's algorithm (K = 0.61). Local TB physicians might have over-diagnosed presumed lymph node TB while under-diagnosing TB overall. Enhancing the precision and promptness of paediatric TB diagnosis using practical tools is pivotal to decrease TB-related child mortality, notably in isolated regions like the Torres Strait and the Western Province of PNG.

Abstract
Introduction Drug-resistant tuberculosis (DR-TB) is a global threat and a challenge for public health authorities worldwide. In children, the diagnosis is even more challenging and DR-TB is poorly described in the literature, as are its treatment outcomes. In this study, we aimed to describe the treatment of drug-resistant TB in children and young adolescents in Brazil. Methods A descriptive epidemiological study of treatment for DR-TB in children under 15 years of age in Brazil between 2013 and 2020. The primary data source was the Information System for Special Tuberculosis Treatments (SITE-TB). Categorical variables were analyzed using relative frequencies (%) and continuous variables by measures of central tendency to characterize the profile of the cases, namely: sociodemographic, clinical characteristics, procedures, tests performed and treatment success. In order to verify the distribution of cases, a spatial analysis was carried out based on the municipality where the cases resided. Results Between 2013 and 2020, 19,757 tuberculosis (TB) cases occurred in children aged <15 years in Brazil, and 46 cases of treatment for DR-TB were reported during the same period (annual average of 6 cases). Of these, 73.9% were aged 10-14, 65.2% were male, 4.3% were HIV+ and 43.3% were underweight (BMI<18.5) at the start of treatment. 17.4% had previous contact with TB, 69.6% had primary resistance, 47.8% multidrug resistance. The median duration of treatment was 15 months. DOT and standardized treatment regimen were performed in 52.2% of cases. Bacilloscopy was performed for 97.8% (57.8% positive); culture for 89.1% (75.6% positive), rapid molecular test for 73.9% with proven resistance to rifampicin in 55.8%. Susceptibility testing revealed resistance mainly to isoniazid (87.8%) and rifampicin (60.6%). 73.9% of cases were successfully treated and one death was reported. Cases were treated in 26 Brazilian municipalities, with the majority in Rio de Janeiro (15) and São Paulo (4). Conclusion DR-TB treatment was recorded in <1% of general TB cases in children and young adolescents, suggesting underreporting of drug-resistant cases in the country. Despite the low number of registered cases, the data reflect the situation of DR-TB in this population and describe important aspects of the problem, as the child needs comprehensive, individualized care, with support from different professionals. We recommend a strengthening of the country's referral services for the care of children with DR-TB so that surveillance and health care services can work together to identify and follow up cases.

Abstract
OBJECTIVE Diagnosing tuberculous meningitis (TBM) in children is challenging due to the low sensitivity with time delay of bacterial culture techniques and the lack of brain imaging facilities in many low- and middle-income settings. This study aims to establish and test a scoring system consisting of clinical manifestations on history and examination for diagnosing TBM in children. DESIGN A retrospective study was conducted using a diagnostic multivariable prediction model. PARTICIPANTS 167 children diagnosed with meningitis (tuberculous, bacterial, viral and others) aged 3 months to 18 years who were hospitalised from July 2011 until November 2021 in a national tertiary hospital in Indonesia. RESULTS Eight out of the 10 statistically significant clinical characteristics were used to develop a predictive model. These resulted in good discrimination and calibration variables, which divided into systemic features with a cut-off score of ≥3 (sensitivity 78.8%; specificity 86.6%; the area under the curve (AUC) value 0.89 (95% CI 0.85 to 0.95; p<0.001)) and neurological features with a cut-off score of ≥2 (sensitivity 61.2%; specificity 75.2%; the AUC value 0.73 (95% CI 0.66 to 0.81; p<0.001)). Combined together, this scoring system predicted the diagnosis of TBM with a sensitivity, specificity and positive predictive value of 47.1%, 95.1% and 90.9%, respectively. CONCLUSION The clinical scoring system consisting of systemic and neurological features can be used to predict the diagnosis of TBM in children with limited resource setting. The scoring system should be assessed in a prospective cohort.

THE LANCET. CHILD & ADOLESCENT HEALTH 2023; 7:708-717. [PMID: 37634517 PMCID: PMC10883460 DOI: 10.1016/s2352-4642(23)00174-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 06/18/2023] [Accepted: 07/03/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND Infants born to women with HIV in settings with a high tuberculosis burden are at risk of tuberculosis infection and rapid progression to active disease. Maternal isoniazid preventive therapy might mitigate this risk, but optimal timing of therapy remains unclear. The TB APPRISE trial showed that initiation of isoniazid during pregnancy resulted in more frequent adverse pregnancy outcomes than when initiated postpartum. We aimed to determine the proportion of infants testing positive for tuberculosis infection born to mothers who initiated isoniazid therapy antepartum compared with postpartum using two commonly used tests, the test agreement, and predictors of test positivity. METHODS TB APPRISE was a randomised, double-blind, placebo-controlled, non-inferiority trial done at 13 study sites across eight countries (Botswana, Haiti, India, South Africa, Tanzania, Thailand, Uganda, and Zimbabwe). Pregnant women with HIV on antiretroviral therapy were randomly assigned to receive immediate isoniazid preventive therapy (28 weeks isoniazid [300 mg daily], then placebo until week 40 after delivery) or deferred treatment (placebo until week 12 after delivery, then isoniazid [300 mg daily] for 28 weeks). Mother-infant pairs were followed up until 48 weeks after delivery. We included all liveborn infants with a tuberculin skin test or interferon-γ release assay (IGRA) at 44 weeks. The outcomes assessed in this secondary analysis were tuberculosis test positivity by study group, test agreement, and predictors of test positivity. This study was registered with ClinicalTrials.gov, NCT01494038. FINDINGS Between Aug 19, 2014, and April 4, 2016, 956 mothers were randomly assigned, and 749 mother-child pairs were included in this secondary analysis. Of 749 infants, 694 (93%) received Bacille Calmette-Guérin (BCG) vaccination, 675 (90%) were born to mothers who had completed isoniazid treatment, 20 (3%) were exposed to tuberculosis, seven (1%) became HIV positive, and one (<1%) developed probable tuberculosis. 43 (6%; 95% CI 4-8]) of 732 infants had a positive IGRA test result and 55 (8%; 6-10) of 727 infants had a positive tuberculin skin test result. Test positivity did not differ by study group (p=0·88 for IGRA; p=0·44 for tuberculin skin test). Test agreement was poor (κ=0·107 [95% CI 0·002-0·212]). Infant tuberculin skin test positivity was associated with breastfeeding (adjusted odds ratio 6·63 [95% CI 1·57-27·9]), BCG vaccination (4·97 [1·50-16·43]), and maternal tuberculin skin test positivity at delivery (3·28 [1·70-6·33]); IGRA positivity was associated with female sex (2·09 [1·06-4·14]). INTERPRETATION Deferral of maternal isoniazid preventive therapy to early postpartum had no effect on infant tuberculosis acquisition in our trial population, regardless of the diagnostic test used; however, tuberculosis test agreement is poor during infancy.

Abstract
Background As childhood tuberculosis is difficult to identify and diagnose, the experiences of the caregivers and healthcare providers of childhood tuberculosis patients remain a potential area of study. This study aims to illustrate the challenges caregivers and healthcare providers encounter in identifying and diagnosing childhood tuberculosis in two sub-districts of Bangladesh. Methods We conducted semi-structured in-depth interviews with eight caregivers of childhood tuberculosis patients and key informant interviews with 36 healthcare providers from September 2020 to December 2020 from different levels of the tuberculosis control program in Keraniganj (with high childhood tuberculosis cases notification), Faridpur Sadar (with low childhood tuberculosis cases notification), and Dhaka city. Results There is a dearth of understanding among caregivers about childhood tuberculosis. Passive case finding process and focus on cough during community mobilisation contribute to the delay in childhood tuberculosis identification. The stigmatisation that caregivers anticipate and experience has an impact on their mental health and implies that there are misunderstandings about tuberculosis in the community. Furthermore, diagnostic dilemma among healthcare providers accounts for diagnosis delays. Some, but not all, institutions in different geographical locations provide free diagnostic tests and have GeneXpert devices. Conclusions Various factors, including caregivers' knowledge and experience, the process of case finding and community mobilization, healthcare providers' way of service provision and diagnosis, and the unavailability of required logistics at facilities challenge the identification and diagnosis of childhood tuberculosis that need to be minimized for childhood tuberculosis's early identification, diagnosis, treatment initiation, and successful completion of treatment. Awareness should also be raised in the community of childhood tuberculosis.

Comparison of single coronal thick-slab minimum intensity projection with flexible bronchoscopy for airway compression in children with lymphobronchial tuberculosis. Clin Radiol 2023; 78:576-583. [PMID: 37308350 DOI: 10.1016/j.crad.2023.03.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 03/01/2023] [Accepted: 03/27/2023] [Indexed: 06/14/2023]
Abstract
AIM To generate standardised coronal minimum intensity projection (MinIP) computed tomography (CT) reconstructions, and compare these with flexible bronchoscopy in children with lymphobronchial tuberculosis (LBTB). MATERIALS AND METHODS Standardised coronal MinIP reconstructions were performed from CT images in children with LBTB and the findings of three readers were compared with the reference standard, flexible bronchoscopy (FB), regarding airway narrowing. Intraluminal lesions, the site of the stenosis, and the degree of stenosis were also evaluated. The length of stenosis was evaluated by CT MinIP only. RESULTS Sixty-five children (38 males; 58.5% and 27 females; 41.5%), with ages ranging from 2.5 to 144 months were evaluated. Coronal CT MinIP demonstrated a sensitivity of 96% and specificity of 89% against FB. The most common site of stenosis was the bronchus intermedius (91%), followed by the left main bronchus (85%), the right upper lobe bronchus RUL (66%), and the trachea (60%). CONCLUSION Coronal CT MinIP reconstruction is useful in demonstrating airway stenosis in children with lymphobronchial TB, with high sensitivity and specificity. CT MinIP had additional advantages over FB in that it allowed objective measurement of the diameter of stenosis, measurement of the length of stenosis, and evaluation of post-stenotic segments of the airways and lung parenchymal abnormalities.

Abstract
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. Practical, evidence-based imaging algorithms are also presented.

Abstract
BACKGROUND The Xpert MTB/rifampicin Ultra (Xpert Ultra) assay improves the early diagnosis of active tuberculosis (TB) in children. Clinical evaluation is paramount for the interpretation of any positive Xpert Ultra test, especially those with low quantities of DNA. METHODS In this study, 391 children with suspected TB who were tested with Xpert Ultra were enrolled. The clinical characteristics and Xpert Ultra results were further analyzed. RESULTS The sensitivity and specificity of Xpert Ultra were 45.0% (149/331) and 96.7% (58/60), respectively. Children with higher semiquantitative scales of Xpert Ultra showed higher percentages of a positive MTB culture, positive acid-fast bacilli staining, severe type of disease, fever, cough and expectoration, a higher white blood cell count and higher C-reactive protein concentrations (all P < 0.01). Among 44 children with an Xpert Ultra trace result, there were no differences in clinical characteristics between confirmed cases and unconfirmed TB cases. CONCLUSIONS The prevalence of trace is relatively high and can be considered positive in paucibacillary children. Clinical presentations are associated with bacterial load quantified by Xpert Ultra. The interpretation of Xpert Ultra trace results based on clinical information is important for the diagnosis of TB.

Abstract
INTRODUCTION An estimated 1.2 million children develop tuberculosis (TB) every year with 240,000 dying because of missed diagnosis. Existing tools suffer from lack of accuracy and are often unavailable. Here, we describe the scientific and clinical methodology applied in RaPaed-TB, a diagnostic accuracy study. METHODS This prospective diagnostic accuracy study evaluating several candidate tests for TB was set out to recruit 1000 children <15 years with presumptive TB in 5 countries (Malawi, Mozambique, South Africa, Tanzania, India). Assessments at baseline included documentation of TB signs and symptoms, TB history, radiography, tuberculin skin test, HIV testing and spirometry. Respiratory samples for reference standard testing (culture, Xpert Ultra) included sputum (induced/spontaneous) or gastric aspirate, and nasopharyngeal aspirate (if <5 years). For novel tests, blood, urine and stool were collected. All participants were followed up at months 1 and 3, and month 6 if on TB treatment or unwell. The primary endpoint followed NIH-consensus statements on categorization of TB disease status for each participant. The study was approved by the sponsor's and all relevant local ethics committees. DISCUSSION As a diagnostic accuracy study for a disease with an imperfect reference standard, Rapid and Accurate Diagnosis of Pediatric Tuberculosis Disease (RaPaed-TB) was designed following a rigorous and complex methodology. This allows for the determination of diagnostic accuracy of novel assays and combination of testing strategies for optimal care for children, including high-risk groups (ie, very young, malnourished, children living with HIV). Being one of the largest of its kind, RaPaed-TB will inform the development of improved diagnostic approaches to increase case detection in pediatric TB.

Surve S, Naukariya K, Shah I. Latent TB in Indian pediatric population: An update on evidence gaps and research needs. Indian J Tuberc 2023; 70 Suppl 1:S8-S13. [PMID: 38110266 DOI: 10.1016/j.ijtb.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 03/31/2023] [Accepted: 04/05/2023] [Indexed: 12/20/2023]
Abstract
The main aim of this article is to review various studies conducted in relation to diagnosis, treatment and management of Latent TB Infection (LTBI) in under-five children, thus highlighting research gaps and further scope of improvements with respect to Indian context. The methodology involved literature review of various online review articles and research papers along with current published guidelines for LTBI management by World Health Organization (WHO) and National tuberculosis Elimination Program (NTEP). There is a dearth of statistically significant data regarding prevalence of LTBI among under-five children in India. LTBI prevalence in Indian adults has been reported between 21 and 48%. The exact prevalence of pediatric LTBI in India is still not clear, however, as per few studies, the LTBI prevalence ranges around 40% and 22% in adolescent followed by under-5 population. Studies to fill in the research gap of scarcity of prevalence data, regarding pediatric LTBI in high TB burden areas of India, is a pivotal step to curb the global pandemic of TB disease. There is a massive undervaluation of the true burden of childhood LTBI as the influence of environmental reservoir in childhood LTBI and TB are not accounted for in pediatric LTBI regimens. Also, there is no substantiate amount of data that highlights the other aspects of LTBI in pediatric population, like awareness regarding LTBI condition and other physiological adverse effects of LTBI in pediatric population, which have been often observed in under-five children suffering from LTBI.

Abstract
BACKGROUND Despite a high paediatric tuberculosis (TB) burden globally, sensitive and specific diagnostic tools are lacking. In addition, no data exist on the impact of pulmonary TB on long-term child lung health in low- and middle-income countries. The prospective observational UMOYA study aims (1) to build a state-of-the-art clinical, radiological, and biological repository of well-characterised children with presumptive pulmonary TB as a platform for future studies to explore new emerging diagnostic tools and biomarkers for early diagnosis and treatment response; and (2) to investigate the short and long-term impact of pulmonary TB on lung health and quality of life in children. METHODS We will recruit up to 600 children (0-13 years) with presumptive pulmonary TB and 100 healthy controls. Recruitment started in November 2017 and is expected to continue until May 2023. Sputum and non-sputum-based samples are collected at enrolment and during follow-up in TB cases and symptomatic controls. TB treatment is started by routine care services. Intensive follow-up for 6 months will allow for TB cases to retrospectively be classified according to international consensus clinical case definitions for TB. Long-term follow-up, including imaging, comprehensive assessment of lung function and quality of life questionnaires, are done yearly up to 4 years after recruitment. DISCUSSION The UMOYA study will provide a unique platform to evaluate new emerging diagnostic tools and biomarkers for early diagnosis and treatment response and to investigate long-term outcomes of pulmonary TB and other respiratory events on lung health in children.

Effect of systematic tuberculosis detection on mortality in young children with severe pneumonia in countries with high incidence of tuberculosis: a stepped-wedge cluster-randomised trial. THE LANCET. INFECTIOUS DISEASES 2023; 23:341-351. [PMID: 36395782 DOI: 10.1016/s1473-3099(22)00668-5] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 09/09/2022] [Accepted: 09/23/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Tuberculosis diagnosis might be delayed or missed in children with severe pneumonia because this diagnosis is usually only considered in cases of prolonged symptoms or antibiotic failure. Systematic tuberculosis detection at hospital admission could increase case detection and reduce mortality. METHODS We did a stepped-wedge cluster-randomised trial in 16 hospitals from six countries (Cambodia, Cameroon, Côte d'Ivoire, Mozambique, Uganda, and Zambia) with high incidence of tuberculosis. Children younger than 5 years with WHO-defined severe pneumonia received either the standard of care (control group) or standard of care plus Xpert MTB/RIF Ultra (Xpert Ultra; Cepheid, Sunnyvale, CA, USA) on nasopharyngeal aspirate and stool samples (intervention group). Clusters (hospitals) were progressively switched from control to intervention at 5-week intervals, using a computer-generated random sequence, stratified on incidence rate of tuberculosis at country level, and masked to teams until 5 weeks before switch. We assessed the effect of the intervention on primary (12-week all-cause mortality) and secondary (including tuberculosis diagnosis) outcomes, using generalised linear mixed models. The primary analysis was by intention to treat. We described outcomes in children with severe acute malnutrition in a post hoc analysis. This study is registered with ClinicalTrials.gov (NCT03831906) and the Pan African Clinical Trial Registry (PACTR202101615120643). FINDINGS From March 21, 2019, to March 30, 2021, we enrolled 1401 children in the control group and 1169 children in the intervention group. In the intervention group, 1140 (97·5%) children had nasopharyngeal aspirates and 942 (80·6%) had their stool collected; 24 (2·1%) had positive Xpert Ultra. At 12 weeks, 110 (7·9%) children in the control group and 91 (7·8%) children in the intervention group had died (adjusted odds ratio [OR] 0·986, 95% CI 0·597-1·630, p=0·957), and 74 (5·3%) children in the control group and 88 (7·5%) children in the intervention group had tuberculosis diagnosed (adjusted OR 1·238, 95% CI 0·696-2·202, p=0·467). In children with severe acute malnutrition, 57 (23·8%) of 240 children in the control group and 53 (17·8%) of 297 children in the intervention group died, and 36 (15·0%) of 240 children in the control group and 56 (18·9%) of 297 children in the intervention group were diagnosed with tuberculosis. The main adverse events associated with nasopharyngeal aspirates were samples with blood in 312 (27·3%) of 1147 children with nasopharyngeal aspirates attempted, dyspnoea or SpO2 less than 95% in 134 (11·4%) of children, and transient respiratory distress or SpO2 less than 90% in 59 (5·2%) children. There was no serious adverse event related to nasopharyngeal aspirates reported during the trial. INTERPRETATION Systematic molecular tuberculosis detection at hospital admission did not reduce mortality in children with severe pneumonia. High treatment and microbiological confirmation rates support more systematic use of Xpert Ultra in this group, notably in children with severe acute malnutrition. FUNDING Unitaid and L'Initiative.

Abstract
BACKGROUND Interferon-gamma release assays (IGRAs) are approved for children ≥2 years old to aid in diagnosis of Mycobacterium tuberculosis (TB) infection and disease. Tuberculin skin tests (TSTs) continue to be the recommended method for diagnosis of TB infection in children <2 years, in part due to limited data and concern for high rates of uninterpretable results. METHODS We performed a retrospective cohort study of IGRA use in patients <2 years old in 2 large Boston healthcare systems. The primary outcome was the proportion of valid versus invalid/indeterminate IGRA results. Secondary outcomes included concordance of IGRAs with paired TSTs and trends in IGRA usage over time. RESULTS A total of 321 IGRA results were analyzed; 308 tests (96%) were valid and 13 (4%) were invalid/indeterminate. Thirty-seven IGRAs were obtained in immunocompromised patients; the proportion of invalid/indeterminate results was significantly higher among immunocompromised (27%) compared with immunocompetent (1%) patients ( P < 0.001). Paired IGRAs and TSTs had a concordance rate of 64%, with most discordant results in bacille Calmette-Guérin-vaccinated patients. The proportion of total TB tests that were IGRAs increased over the study period (Pearson correlation coefficient 0.85, P < 0.001). CONCLUSIONS The high proportion of valid IGRA test results in patients <2 years of age in a low TB prevalence setting in combination with the known logistical and interpretation challenges associated with TSTs support the adoption of IGRAs for this age group in certain clinical scenarios. Interpretation of IGRAs, particularly in immunocompromised patients, should involve consideration of the broader clinical context.

Abstract
Background: Despite being a preventable and treatable disease, tuberculosis (TB) is a leading cause of death among young people globally. Each year, an estimated 1.8 million adolescents and young adults (AYAs; 10–24 years old) develop TB. In 2019, an estimated 161,000 AYAs died of the disease. AYAs have unique developmental, psychosocial, and healthcare needs, but these needs have been neglected in both TB care and research agendas. In order to improve outcomes in this age group, the specific needs of AYAs must be considered and addressed. Methods: Through a consensus process, an international panel of 34 clinicians, researchers, TB survivors, and advocates with expertise in child/adolescent TB and/or adolescent health proposed interventions for optimizing AYA engagement in TB care. The process consisted of reviewing the literature on TB in AYAs; identifying and discussing priority areas; and drafting and revising proposed interventions until consensus, defined a priori , was reached. Results: The panel acknowledged the dearth of evidence on best practices for identifying and managing AYAs with TB. The final consensus statement, based on expert opinion, proposes nine interventions to reform current practices that may harm AYA health and well-being, and nine interventions to establish high-quality AYA-centered TB services. Conclusion: AYA-specific interventions for TB care and research are critical for improving outcomes in this age group. In the absence of evidence on best practices, this consensus statement from an international group of experts can help address the needs of AYA with TB or at risk for TB.

Eur J Pediatr 2023; 182:2155-2167. [PMID: 36847873 PMCID: PMC9969014 DOI: 10.1007/s00431-023-04844-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 10/25/2022] [Accepted: 01/23/2023] [Indexed: 03/01/2023]
Abstract
Commercially available Interferon-γ release assays (IGRAs), including the last-generation QuantiFERON TB-Plus (QFT-Plus), are effective in aiding the diagnosis of tuberculosis (TB) infection but cannot distinguish latent TB subjects from active TB patients. The aim of this study was to prospectively evaluate the performance of an HBHA-based IGRA, combined with commercially available IGRAs, to assess their usefulness as a prognostic biomarkers and aid in the monitoring of TB treatment in children. Following clinical, microbiological, and radiological assessment, children younger than 18 years of age classified as either LTBI or active TB were tested at baseline and during treatment by the QuantiFERON TB-Plus (QFT) assay and an aliquot of whole-blood was stimulated with HBHA. Among the 655 children evaluated, 559 (85.3%) were classified as "Non TB", 44 patients (6.7%) with active TB, and 52 (7.9%) with LTBI. The median HBHA-IGRA IFN-gamma responses were able to discriminate active TB from LTBI (0.13 IU/ml vs 1.995, (p < 0,0001), those with asymptomatic TB from those with symptomatic TB (1.01 IU/ml vs 0.115 IU/ml, p 0.017), or more severe TB (p 0.022), and significantly raised during successful TB treatment (p < 0.0001). Conversely, CD4 + and CD8 + responses were similar in all groups of patients, although active TB patients had higher CD4 + responses and LTBI higher CD8 + responses. Conclusion: HBHA-based IGRA, combined with CD4 + and CD8 + responses assessed by commercially available IGRAs, is a useful support in the characterization of the TB spectrum in children and monitoring of TB-therapy. What is Known: • Current immune diagnostics are not able to discriminate active and latent Ttuberculosis, including the recently approved QFT-PLUS.. • New immunological assays with prognostic value are highly needed. What is New: • HBHA-based IGRA, combined with CD4+ and CD8+ responses assessed by commercially available IGRAs, is a useful support for the differentiation of active and latent TB in children.. • HBHA-based IGRA, combined with CD4+ and CD8+ responses assessed by commercially available IGRAs, is a useful support in the monitoring of TBtherapy in children..

Association of Sociodemographic Factors with Tuberculosis Outcomes in Mississippi. Diseases 2023; 11:diseases11010025. [PMID: 36810538 PMCID: PMC9944444 DOI: 10.3390/diseases11010025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/09/2023] [Accepted: 01/29/2023] [Indexed: 02/04/2023] Open
Abstract
Tuberculosis (TB) is one of the leading causes of death worldwide. In the US, the national incidence of reported TB cases was 2.16 per 100,000 persons in 2020 and 2.37 per 100,000 persons in 2021. Furthermore, TB disproportionately affects minorities. Specifically, in 2018, 87% of reported TB cases occurred in racial and ethnic minorities in Mississippi. Data from TB patients from the Mississippi Department of Health (2011-2020) were used to examine the association between sociodemographic subgroups (race, age, place of birth, gender, homelessness, and alcohol use) with TB outcome variables. Of the 679 patients with active TB cases in Mississippi, 59.53% were Black, and 40.47% were White. The mean age was 46 ± ten years; 65.1% were male, and 34.9% were female. Among patients with previous TB infections, 70.8% were Black, and 29.2% were White. The rate of previous TB cases was significantly higher among US-born (87.5%) persons compared with non-US-born persons (12.5%). The study suggested that sociodemographic factors play a significant role in TB outcome variables. This research will help public health professionals to develop an effective TB intervention program that addresses sociodemographic factors in Mississippi.

Adequacy of the 10 mg/kg Daily Dose of Antituberculosis Drug Isoniazid in Infants under 6 Months of Age. Antibiotics (Basel) 2023; 12:antibiotics12020272. [PMID: 36830184 PMCID: PMC9952805 DOI: 10.3390/antibiotics12020272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 01/21/2023] [Accepted: 01/28/2023] [Indexed: 01/31/2023] Open
Abstract
In 2010, the WHO recommended an increase in the daily doses of first-line anti-tuberculosis medicines in children. We aim to characterize the pharmacokinetics of the once-daily isoniazid (INH) dose at 10 mg/kg of body weight in infants <6 months of age. We performed a multicenter pharmacokinetic study in Spain. The N-acetyltransferase 2 gene was analyzed to determine the acetylation status. Samples were analyzed using a validated UPLC-UV assay. A non-compartmental pharmacokinetic analysis was performed. Twenty-three pharmacokinetic profiles were performed in 20 infants (8 females) at a median (IQR) age of 19.0 (12.6-23.3) weeks. The acetylator statuses were homozygous fast (n = 1), heterozygous intermediate (n = 12), and homozygous slow (n = 7). INH median (IQR) Cmax and AUC0-24h values were 4.8 (3.7-6.7) mg/L and 23.5 (13.4-36.7) h*mg/L and the adult targets (>3 mg/L and 11.6-26.3 h*mg/L) were not reached in three and five cases, respectively. The age at assessment or acetylator status had no impact on Cmax values, but a larger INH AUC0-24h (p = 0.025) and trends towards a longer half-life (p = 0.055) and slower clearance (p = 0.070) were observed in homozygous slow acetylators. Treatment was well tolerated; mildly elevated alanine aminotransferase levels were observed in three cases. In our series of young infants receiving isoniazid, no major safety concerns were raised, and the target adult levels were reached in most patients.

Abstract
Introduction Annually, tens of millions of children are being exposed to tuberculosisinfection. Note that children are in higher risk of getting infection and sever types of the disease, detecting the factors associated with transmission of the tuberculosis infection and disease to the exposed children is necessary for disease prevention within the community. Methods In this retrospective cohort study, 50 children under 6 who were in close contact with 25 smear-positive pulmonary tuberculosis cases in Sistan-Baloochistanprovine, Iran, were investigated. Demographic, behavioral and clinical characteristics of children and index cases were collected and tuberculosis infection and disease was assessed using the WHO guidelines. Results Of 50 children exposed to the active cases, 12 (24 %) were infected to tuberculosis but none of them had active disease. We also found significant associations of the history of diabetes mellitus in the index cases (p = 0.043) and large family size (p = 0.026) with the increased risk of infection among the exposed children. Conclusion Children under six which are in close contact with diabetic tuberculosis cases in large families are in higher risk of getting infection.

Abstract
BACKGROUND Nigeria is one of the thirty high burden countries with significant contribution to the global childhood tuberculosis epidemic. Tuberculosis annual risk for children could be as high as 4% particularly in high tuberculosis (TB) prevalent communities. Isoniazid (INH) Preventive Therapy has been shown to prevent TB incidence but data on its implementation among children are scarce.
AIM To determine the completion of INH among under six children that were exposed to adults with smear positive pulmonary TB in Lagos, Nigeria.
METHODS This was a hospital-based retrospective cross-sectional review of 265 medical records of eligible children < 6 years old enrolled for INH across 32 private hospitals in Lagos, Nigeria. The study took place between July and September 2020. Data was collected on independent variables (age, gender, type of facility, TB screening, dose and weight) and outcome variables (INH outcome and proportion lost to follow up across months 1-6 of INH treatment).
RESULTS About 53.8% of the participants were female, 95.4% were screened for TB and none was diagnosed of having TB. The participants’ age ranged from 1 to 72 mo with a mean of 36.01 ± 19.67 mo, and 40.2% were between the ages of 1-24 mo. Only 155 (59.2%) of the 262 participants initiated on INH completed the six-month treatment. Cumulatively, 107 (41.0%) children were lost to follow-up at the end of the sixth month. Of the cumulative 107 loss to follow-up while on INH, largest drop-offs were reported at the end of month 2, 52 (49%) followed by 20 (19%), 17 (16%), 11 (10.2%) and 7 (6.5%) at months 3, 4, 5 and 6 respectively. The analysis showed that there was no significant association between age, gender, type of facility and completion of INH treatment (P > 0.005).
CONCLUSION This study demonstrated suboptimal INH completion rate among children with only 6 out of 10 children initiated on INH who completed a 6-mo treatment in Lagos, Nigeria. The huge drop-offs in the first 2 mo of INH calls for innovative strategies such as the use of 60-d INH calendar that would facilitate reminder and early engagement of children on INH and their caregivers in care and across the entire period of treatment.

Abstract
Pneumonia is the number one cause of disease and deaths in children under five years old, outside the neonatal period, with the greatest number of cases reported from resource-limited settings. The etiology is variable, with not much information on the local etiology drug resistance profile in many countries. Recent studies suggest an increasing contribution from respiratory viruses, also in children with severe pneumonia, with an increased relative contribution in settings that have good vaccine coverage against common bacterial pathogens. Respiratory virus circulation was greatly reduced during highly restrictive measures to contain the spread of COVID-19 but rebounded once COVID-19 restrictions were relaxed. We conducted a comprehensive literature review of the disease burden, pathogens, case management and current available prevention of community acquired childhood pneumonia, with a focus on rational antibiotic use, since the treatment of respiratory infections is the leading cause of antibiotic use in children. Consistent application of revised World Health Organisation (WHO) guidance that children presenting with coryzal symptoms or wheeze can be managed without antibiotics in the absence of fever, will help to reduce unnecessary antibiotic use, as will increased availability and use of bedside inflammatory marker tests, such as C-reactive protein (CRP) in children with respiratory symptoms and fever.

Abstract
The burden of tuberculosis (TB) in children and adolescents remains very significant. Several million children and adolescents are infected with TB each year worldwide following exposure to an infectious TB case and the risk of progression from TB infection to tuberculosis disease is higher in this group compared to adults. This review describes the risk factors for TB infection in children and adolescents. Following TB exposure, the risk of TB infection is determined by a combination of index case characteristics, contact features, and environmental determinants. We also present the recently recommended approaches to diagnose and treat TB infection as well as novel tests for infection. The tests for TB infection have limitations and diagnosis still relies on an indirect immunological assessment of cellular immune response to Mycobacterium tuberculosis antigens using immunodiagnostic testing. It is recommended that TB exposed children and adolescents and those living with HIV receive TB preventive treatment (TPT) to reduce the risk of progression to TB disease. Several TPT regimens of similar effectiveness and safety are now available and recommended by the World Health Organisation.

Abstract
Tuberculosis (TB) remains a leading cause of illness and death throughout the world. Despite its high prevalence worldwide, a diagnosis of TB can be hampered by variable clinical presentation, differences in host response, and lack of clinician awareness. In addition to the lungs, TB can affect almost every organ system in the body. Importantly, the severity of the disease is influenced by the age and immune status of the patient. Because it is relatively rare in the United States and other high-income countries, pediatricians in those settings may be unfamiliar with this ancient disease and may omit it from their differential diagnosis. This article aims to bring general pediatricians up to date with the epidemiology of pediatric TB as well as common presentations and screening tests. Confirmatory testing and treatment of TB are out of the scope of this article. Consultation with the local health department is recommended for any patients in whom active TB is suspected or diagnosed. [Pediatr Ann. 2022;51(12):e461-e468.].

Abstract
The reported prevalence of tuberculous bronchial stenosis in children is unknown and rarely reported in English-speaking literature. In adult patients with pulmonary tuberculosis, it varies from 40% in an autopsied series in the preantibiotic era to 10% in patients who have undergone routine bronchofibroscopy in modern times. We describe our experience of four cases of confirmed bronchial stenosis due to MTB collected between January 2000 and June 2021 in this case series descriptive study. The diagnosis of bronchial stenosis due to TB was made on flexible bronchoscopy. A TB diagnosis was made if MTB was cultured from respiratory secretions, when Ziehl-Neelsen smear or GeneXpert MTB/RIF test was positive, or if a chest radiograph revealed radiographic features typical of MTB. Bronchial stenosis due to TB is rare even if airway compression is frequently seen. Although an early diagnosis of bronchial stenosis due to TB is difficult on chest X-rays, all children in this series demonstrated parenchymal changes distal to the stenosis ranging from hyperinflation and lobar collaps to bronchiectasis. If bronchial stenosis resulting from TB disease is diagnosed early, balloon dilatation as described in this report, may be an effective and safe intervention, preventing long-term complications such as irreversible lung destruction, that may require pneumonectomy.

Abstract
Rationale: Although World Health Organization guidelines emphasize contact investigation for tuberculosis (TB)-exposed children, data that support chest radiography as a useful tool are lacking. Objectives: We evaluated the diagnostic and prognostic information of chest radiography in children exposed to TB and measured the efficacy of isoniazid preventive therapy (IPT) in those with relevant radiographic abnormalities. Methods: Between September 2009 and August 2012, we enrolled 4,468 TB-exposed children who were screened by tuberculin skin testing, symptom assessment, and chest radiography. Those negative for TB disease were followed for 1 year for the occurrence of new TB diagnoses. We assessed the protective efficacy of IPT in children with and without abnormal chest radiographs. Measurements and Main Results: Compared with asymptomatic children with normal chest films, asymptomatic children with abnormal radiographs were 25.1-fold more likely to have coprevalent TB (95% confidence interval [CI], 1.02-613.76) and 26.7-fold more likely to be diagnosed with incident TB disease during follow-up (95% CI, 10.44-68.30). Among the 29 symptom-negative and CXR-abnormal child contacts, 20% (3/15) of the isoniazid recipients developed incident TB, compared with 57% (8/14) of those who did not receive IPT (82% IPT efficacy). Conclusions: Our results strongly support the use of chest radiography as a routine screening tool for the evaluation of child TB contacts, which is readily available. Radiographic abnormalities not usually considered suggestive of TB may indicate incipient or subclinical disease, although TB preventive treatment is adequate in most cases.

Abstract
In 2014, the World Health Organization developed the End Tuberculosis Strategy with the goal of a 95% reduction in deaths from tuberculosis (TB) by 2035. The start of the COVID-19 pandemic and global lockdown has had a major impact on TB awareness, screening, diagnosis, and prompt initiation of treatment, inevitably leading to a significant setback. We explore pediatric tuberculosis through the lens of the COVID-19 era, investigating how COVID-19 has impacted pediatric TB cases in different regions of the world and what the implications are for management moving forward to mitigate these effects. Furthermore, in light of recent findings showing how exposed infants and children are at higher risk than we thought of contracting the disease, greater attention and resources are needed to prevent further downward trends.
