TB in children presents unique challenges due to its subtle clinical manifestations and paucibacillary nature, often resulting in difficulties in diagnosis. Compared to estimated incidence, only 49% children were diagnosed and reported, with the highest proportion of under-reporting taking place in children under 5 years - of 58%. Gaps and challenges persist in accurately diagnosing and treating TB in children, stemming from limitations in traditional diagnostic methods, like sputum culture, that often lack sensitivity and specificity in children. Therefore, there is a pressing need to identify new diagnostic techniques that are both accurate and feasible in pediatric settings.\n\nIn recent years, researchers have explored innovative approaches, including the utilization of alternative sample types such as mask samples, urine, or stool, for TB diagnosis in children. These alternative samples offer potential advantages in terms of ease of collection and potentially improved diagnostic accuracy. In 2021, the World Health Organization (WHO) recommended stool as an alternative sample for TB diagnosis in children with signs and symptoms of TB, since stool is non-invasive and easy to collect even in young children. A recent systematic review showed that Xpert Ultra summary sensitivity verified by culture was 56.1% (95% CI 39.1 to 71.7), and specificity was 98.0% (95% CI 93.3 to 99.4), nevertheless the sensitivity results are highlighted as \"moderate quality evidence\", therefore more research is needed on the performance of this alternative sample in children for the diagnosis of tuberculosis. Moreover, the lipoarabinomannan (LAM) found in the membrane of the Mycobacterium tuberculosis bacillus can be identified in urine and pilot data generated by our group shows a sensitivity of 66% in adults with culture-confirmed pulmonary tuberculosis. This urine-based assay can be critically useful in the diagnosis of extrapulmonary TB as it's not sputum-based. In addition to stool and urine, another promising sample can be obtained through a gelatin strip inside a mask worn by children with presumptive TB. The exhaled breath potentially containing M. tuberculosis bacilli is then captured on the gelatin filter, processed, and tested using GeneXpert.\n\nOnce the tuberculosis diagnosis is made, an important challenge lies in drug susceptibility testing (DST), in case of multi-drug resistant TB or rifampicin-resistant TB (MDR\u002FRR-TB)(6). The standard of care for DST is sputum culture, which has many challenges in children, as highlighted above. Targeted next-generation sequencing (tNGS) has emerged as a promising tool for assessing drug sensitivity, providing valuable insights into personalized treatment regimens for pediatric TB cases. In addition, tNGS can be performed on clinical samples like sputum or stool with the potential of a rapidly-available result informing the choice of regimen and clinical decision-making.\n\nAfter treatment initiation, a main concern lies in treatment monitoring, this step being especially challenging in children. Transcriptomics holds promise for monitoring treatment response in children with TB. By examining gene expression patterns, transcriptomic analyses can offer valuable insights into the efficacy of treatment regimens and help identify early indicators of treatment failure or relapse. Both WHO definitions and TBnet definitions will be used to assess TB outcomes.\n\nUnderstanding and assessing the burden of post-TB sequelae in children is crucial for ensuring comprehensive care and addressing long-term health outcomes. Therefore, studying and evaluating port-TB disease in children is imperative for improving clinical management strategies and enhancing the overall health outcomes of pediatric TB patients. Spirometry will be used to assess pulmonary function in children.\n\nThis study aims to research a novel and comprehensive approach to TB diagnosis, treatment adaptation, and treatment monitoring in the pediatric population, with the overall goal of improving TB outcomes in children.\n\nAims and objectives\n\nAim: Improve the diagnosis of tuberculosis and treatment outcomes in children evaluated for tuberculosis\n\nSpecific objectives:\n\n1. Identify the diagnostic accuracy of mask strip samples against a composite reference standard for the diagnosis of respiratory tuberculosis in children.\n2. Determine the diagnostic accuracy of a novel urinary LAM assay against a composite reference standard for the diagnosis of respiratory tuberculosis in children.\n3. Evaluate the diagnostic accuracy of stool and perform targeted next generation sequencing from stool for drug sensitivity testing.\n4. Assess the utility of a transcriptomic signature for treatment monitoring and treatment shortening in children treated for respiratory tuberculosis.\n5. Measure the pulmonary function changes in children diagnosed with respiratory tuberculosis using spirometry.\n6. Assess the quality of life of children treated for respiratory tuberculosis at baseline, during, and after treatment.","All potential participants presenting with the inclusion criteria, will be asked to participate in the study upon their parent\u002Fguardian consent and their assent, if applicable. Information will be provided about the study and the risks and benefits of participating. Both the child and the parent\u002Fguardian are then asked to consent (or assent) to the participation in the study and any questions they might have are answered. The enrollment is complete after the signature of the informed consent form (ICF).
