To strengthen diagnostic capacity, two novel tools will be evaluated: stool-based GeneXpert testing (a method recommended in children and explored here as a feasible alternative for pregnant women) and artificial intelligence-powered chest X-ray interpretation software designed to enhance TB detection where radiological expertise is lacking.\n\nThe study will also generate comprehensive, population-based data on TB and TB infection (TBI) among pregnant, postpartum women and women of reproductive age in Guinea-Bissau. The results are intended to inform health policy, both locally and in high-income countries, by providing evidence to improve TB screening protocols and care for this vulnerable group. Ultimately, the study seeks to develop scalable strategies that can be replicated across low- and middle-income countries to advance maternal and child health and support global TB eradication efforts.",[28,29,216,217,218],"Pregnancy","Tuberculosis Diagnosis","Maternal Health","2026-02-14",{"date":221,"type":40},"2026-02-19",{"date":223,"type":22},"2026-02",{"date":225,"type":22},"2027-11",{"name":227,"class":47},"Aarhus University Hospital",{"id":229,"slug":230,"hasResults":11,"nctId":231,"briefTitle":232,"officialTitle":233,"acronym":234,"eligibilityCriteria":235,"healthyVolunteers":11,"sex":18,"minAge":55,"maxAge":236,"enrollmentInfo":237,"targetDuration":4,"studyType":23,"phases":239,"briefSummary":240,"conditions":241,"keywords":245,"overallStatus":160,"whyStopped":4,"lastUpdateSubmitDate":251,"lastUpdatePostDateStruct":252,"startDateStruct":254,"completionDateStruct":256,"leadSponsor":258,"locationsCount":260},"100599617","window-prophylaxis-for-pediatric-tuberculosis-prevention-trial-100599617","NCT07086820","Window Prophylaxis for Pediatric Tuberculosis Prevention Trial","Window Prophylaxis for Mycobacterium Tuberculosis Infection Prevention in Child and Adolescent Household Contacts: a Cluster-Randomized Controlled Trial","TB-WIN","Inclusion Criteria:\n\n* Household contacts of patient (index case) with a new diagnosis of microbiologically confirmed pulmonary tuberculosis\n* Age ≥5 to \\\u003C18 years old\n\nExclusion Criteria:\n\n* Suspected active tuberculosis in initial assessment (clinical or radiological)\n* Current pregnancy or breastfeeding\n* Immunocompromised\n* Allergy or contraindication to isoniazid or rifapentine\n* Chronic liver disease or alcohol use disorder\n* History of previous treatment for active or latent tuberculosis infection\n* Previous tuberculin skin test\n* Household contacts of a tuberculosis index patient with a known or suspected drug-resistant M. tuberculosis strain\n* Household contacts or a tuberculosis index patient currently living away from home for more than four weeks\n* Household contacts of a tuberculosis index patient who have already received more than 15 daily doses of antituberculous treatment","17 Years",{"count":238,"type":22},647,[25],"The goal of this cluster-randomized controlled trial is to evaluate the effectiveness of tuberculosis preventive treatment (TPT) administered during the \"window period\" to prevent new Mycobacterium tuberculosis infections in children and adolescents.\n\nThe main question it aims to answer is:\n\nCan immediate TPT reduce the incidence of IGRA conversions in children and adolescents who are household contacts of a newly diagnosed pulmonary tuberculosis patient?\n\nResearchers will compare the incidence of new tuberculosis infections-measured by IGRA conversion at 12 weeks-between participants who receive immediate TPT while still uninfected (baseline IGRA-negative) and those who receive standard care, in which TPT is not offered to IGRA-negative contacts.\n\nParticipants will be:\n\n1.
