EP23-319-23-Chest-X-ray for TB diagnosis in children under 5 years living with a person with bacteriologically confirmed pulmonary TB in Africa: quality, inter-reader agreement and performancesThis study evaluates quality, inter-reader agreement and performances of chest X-rays (CXR) for tuberculosis (TB) diagnosis in children under 5 years of age, who are living with a person with bacteriologically-confirmed pulmonary TB, as part of a contact investigation study using systematic CXR.

EP23-320-23-Classification and regression trees to predict TB disease in childrenThe diagnosis of tuberculosis (TB) disease in children is complicated by non-specific symptoms and low sensitivity of conventional diagnostic tests. We use classification and regression tree analysis to identify the best predictors for accurately classifying children (0-4, 5-9 and 10-14- years-old), who are exposed at home to TB, with TB disease.

EP23-321-23-Epidemiology and clinical manifestations of adolescent TB in UkraineWe analysed data from 2491 cases of adolescent tuberculosis (TB) in Ukraine. We identified risk factors for each of four clinical presentations: cavitary, pleural, extrathoracic and rifampicin-resistant TB. This work can help guide diagnosis and clinical decision making in a traditionally overlooked age group for TB.

EP23-322-23-Prevalence and predictive factors of active TB in children under 5 years of age living with a person with bacteriologically-confirmed pulmonary TB in AfricaOur study was conducted in four African countries to identify factors predictive of active tuberculosis (TB) in children under 5 years of age living in contact with a bacteriologically-confirmed pulmonary TB case. The factors identified can be used to create a score to screen for childhood TB during home visits.

EP23-323-23-Childhood TB trends in Zambia over five years (2014-2019)Childhood tuberculosis (TB) has been underserved until recent years when there has been renewed national commitment. The Zambian Ministry of Health, through the National Tuberculosis Programme, has embarked on high impact, data driven interventions aimed at turning the tide that once seemed grim as shown by this trend analysis.

EP23-324-23-Routine South African TB data: are we doing enough for children and adolescents?Although children and adolescents with tuberculosis (TB) are globally recognised as important key populations, limited approaches exist to evaluate how well TB programmes address these groups.  We used routine data to analyse TB case notification indicators disaggregated by age (0-4, 5-9, 10-14 and 15-19 years) and discuss South Africa‚Äôs progress.

16:30 - 16:35: Introduction


16:35 - 16:43: OA-31-688-23-Estimating the proportion of subclinical TB disease: definitions, associations and screening A significant proportion of the global tuberculosis (TB) burden is subclinical, it is not detectable by current symptom-based screening efforts and is fueling the TB epidemic through continued Mycobacterium tuberculosis transmission. We extracted data from TB prevalence surveys conducted since 1990 and our results revealed the potential of changing TB case finding policies.

Beatrice Frascella

16:43 - 16:51: OA-31-689-23-A high-resolution snapshot of subclinical TB via community-wide sputum testing in an urban Ugandan community We performed population-wide, community-based tuberculosis (TB) testing with sputum Xpert MTB/RIF Ultra for >12,000 adults within a two km2 area, in Kampala, Uganda. We compared clinical and bacteriologic characteristics of individuals with undiagnosed TB, to patients diagnosed through routine care at local health facilities, and also to representative TB-negative community members.

Emily Kendall

16:51 - 16:59: OA-31-690-23-Methods and challenges of national TB prevalence surveys in Asia and sub-Saharan Africa: a systematic review This systematic review characterised the methodological challenges of 28 national TB prevalence surveys in Asia and sub-Saharan Africa. Challenges included under-recruitment, under-representation of risk groups, diagnostic reliance on smear as well as logistical constraints including staffing, security and paper-based tools. Solutions included improved funding, political commitment, context-specific diagnostic algorithms and social mobilisation.

Gokul Mishra

16:59 - 17:07: OA-31-691-23-Trends in molecular epidemiology of drug-resistant TB in Estonia Estonia is on the list of 18 high-priority countries for tuberculosis (TB) control that bear 85% of the TB burden and 99% of the multidrug-resistant-TB burden. The study aimed to characterise Mycobacterium tuberculosis isolates, obtained at different time points in Estonia, to assess trends in evolution of drug-resistant TB.

Igor Mokrousov

17:07 - 17:15: OA-31-692-23-Comparing the epidemiology and clinical characteristics of childhood TB through active and passive case finding Most high prevalence areas perform only passive case finding (PCF) for tuberculosis (TB), evaluating children presenting with significant symptoms, rather than active case finding (ACF) through contact tracing. We compared clinical, radiographic and microbiological characteristics of children diagnosed through ACF and PCF and found important differences that impact recognition and care.

Saki Ikeda

17:15 - 17:23: OA-31-693-23-Increasing TB incidence rates and inequitable treatment outcomes for young people with TB in Brazil: a national retrospective cohort study We conducted a national retrospective cohort study in Brazil between 2015-2018 of 42,291 young people newly diagnosed with TB. We found increasing tuberculosis (TB) incidence in young people and those with homelessness, HIV/AIDS, illicit drug use or identifying with black or brown skin colour, were more likely to have unfavourable treatment outcomes.
