High risk of drug-resistant tuberculosis in IGRA-negative contacts: should preventive treatment be considered?

Purpose: Deciding whether to provide preventive treatment to contacts of individuals with multidrug-resistant (MDR) tuberculosis is complex.

Methods: We present the diagnostic pathways, clinical course and outcome of tuberculosis treatment in eight siblings from a single family. Tuberculosis disease was diagnosed by Mycobacterium tuberculosis culture and molecular detection of M.

Facilitators and barriers to initiating and completing tuberculosis preventive treatment among children and adolescents living with HIV in Uganda: a qualitative study of adolescents, caretakers and health workers.

Introduction: People living with HIV (PLHIV) have a 20-fold risk of tuberculosis (TB) disease compared to HIV-negative people. In 2021, the uptake of TB preventive treatment among the children and adolescents living with HIV at the Baylor-Uganda HIV clinic was 45%, which was below the national target of 90%. Minimal evidence documents the enablers and barriers to TB preventive treatment (TPT) initiation and completion among children and adolescents living with HIV(CALHIV).

Whispers in the Wind: Face Mask Sampling for Mycobacterium tuberculosis Detection in Children With Pulmonary Tuberculosis.

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.

Predicting mortality within 1 year of ART initiation in children and adolescents living with HIV in sub-Saharan Africa: a retrospective observational cohort study.

Background: Differentiated service delivery (DSD) for children and adolescents living with HIV can improve targeted resource use. We derived a mortality prediction score to guide clinical decision making for children and adolescents living with HIV.

Methods: Data for this retrospective observational cohort study were evaluated for all children and adolescents living with HIV and initiating antiretroviral therapy (ART); aged 0-19 years; and enrolled at Baylor clinics in Eswatini, Malawi, Lesotho, Tanzania, and Uganda between 2005 and 2020.

Performance of a stool-based quantitative PCR assay for the diagnosis of tuberculosis in adolescents and adults: a multinational, prospective diagnostic accuracy study.

Background: Despite increasing availability of rapid molecular tests for the diagnosis of tuberculosis in high-burden settings, many people with tuberculosis are undiagnosed. Reliance on sputum as the primary specimen for tuberculosis diagnostics contributes to this diagnostic gap. We evaluated the diagnostic accuracy and additive yield of a novel stool quantitative PCR (qPCR) assay for the diagnosis of tuberculosis in three countries in Africa with high tuberculosis burdens.

Tuberculosis incidence in foreign-born people residing in European countries in 2020.

BackgroundEuropean-specific policies for tuberculosis (TB) elimination require identification of key populations that benefit from TB screening.AimWe aimed to identify groups of foreign-born individuals residing in European countries that benefit most from targeted TB prevention screening.MethodsThe Tuberculosis Network European Trials group collected, by cross-sectional survey, numbers of foreign-born TB patients residing in European Union (EU) countries, Iceland, Norway, Switzerland and the United Kingdom (UK) in 2020 from the 10 highest ranked countries of origin in terms of TB cases in each country of residence.

Pathogenesis of tuberculosis: the 1930 Lübeck disaster revisited.

During the 1930 Lübeck bacille Calmette-Guérin (BCG) disaster, 251 neonates received three oral BCG doses accidentally contaminated by virulent ; 67 (26.7%) infants died of tuberculosis. BCG reversion to pathogenicity did not occur.

Quality matters: Redefining child TB care with an emphasis on quality.

Children have been neglected in the fight against tuberculosis (TB) for decades. Despite being the number one infectious disease killer, TB does not feature on the child survival agendas partly due to absent and inaccurate data. Quality is a missing ingredient in TB care in children, yet high rates of unfavorable TB outcomes highlight its importance in this age group.

Management of drug-resistant tuberculosis.

Drug-resistant tuberculosis is a major public health concern in many countries. Over the past decade, the number of patients infected with Mycobacterium tuberculosis resistant to the most effective drugs against tuberculosis (ie, rifampicin and isoniazid), which is called multidrug-resistant tuberculosis, has continued to increase. Globally, 4·6% of patients with tuberculosis have multidrug-resistant tuberculosis, but in some areas, like Kazakhstan, Kyrgyzstan, Moldova, and Ukraine, this proportion exceeds 25%.

HIV-associated pediatric tuberculosis: prevention, diagnosis and treatment.

Purpose Of Review: The detrimental synergy of colliding HIV and tuberculosis (TB) epidemics is most devastating among children and adolescents living with HIV (CALWH) who shoulder a disproportionate burden of all child TB mortality.

Recent Findings: CALWH benefit less from Bacille-Calmette Guerin vaccination than HIV-uninfected children and are not receiving TB preventive therapy despite global recommendations. Further, the predictive utility of most diagnostic tools is reduced in CALWH.

School and household tuberculosis contact investigations in Swaziland: Active TB case finding in a high HIV/TB burden setting.

Background: Investigation of household contacts exposed to infectious tuberculosis (TB) is widely recommended by international guidelines to identify secondary cases of TB and limit spread. There is little data to guide the use of contact investigations outside of the household, despite strong evidence that most TB infections occur outside of the home in TB high burden settings. In older adolescents, the majority of infections are estimated to occur in school.

BUTIMBA: Intensifying the Hunt for Child TB in Swaziland through Household Contact Tracing.

Background: Limited data exists to inform contact tracing guidelines in children and HIV-affected populations. We evaluated the yield and additionality of household contact and source case investigations in Swaziland, a TB/HIV high-burden setting, while prioritizing identification of childhood TB.

Methods: In partnership with 7 local TB clinics, we implemented standardized contact tracing of index cases (IC) receiving TB treatment.

Predictive value of immunization records and risk factors for immunization failure in internationally adopted children.

Objectives: To measure the predictive value of immunization records for protective immunity and identify risk factors for immunization failure.

Design: Prospective cross-sectional study, 2001-2006.

Setting: International Adoption Clinic, Rainbow Babies and Children's Hospital, Cleveland, Ohio.
