SETTING: The paediatric oncology unit at Tygerberg Children's Hospital, South Africa. OBJECTIVES: To assess the use of the tuberculin skin test (TST) and two commercial interferon-gamma release assays (IGRAs) for the ...

BACKGROUND: Ethionamide (ETH) is a structural analogue of isoniazid (INH). Both are pro-drugs requiring activation by separate and common enzyme pathways, which could lead to co-and/or cross-resistance. OBJECTIVE: To ...

Exposure to TB was quantified by screening human immunodeficiency virus (HIV) exposed infants aged 3-4 months for an isoniazid prophylaxis study where tuberculosis (TB) exposure excluded enrolment. Seventy-seven (10.1%, ...
