Pyrazinamide plasma concentrations in young children with tuberculosis
(2011)
Pyrazinamide plasma concentrations were determined in 34 children (median age, 3.32 years) 1 month after commencing antituberculosis treatment. The median (interquartile range) peak concentration was 30.7 (25.5, 35.0) mg/L ...
Interferon-gamma release assays for the detection of Mycobacterium tuberculosis infection in children with cancer
(2010)
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 ...
Tuberculosis exposure in HIV-exposed infants in a high-prevalence setting
(2008)
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%, ...
Pyridoxal-5-phosphate plasma concentrations in children receiving tuberculosis chemotherapy including isoniazid
(2010)
Aim: Little is known about pyridoxine nutriture of children treated with isoniazid (INH) regimens. This study documents plasma pyridoxal 5′-phosphate (PLP) concentrations in children, HIV-infected and HIV-uninfected, ...
Childhood drug-resistant tuberculosis in the Western Cape Province of South Africa
(2006)
Aim: Continued surveillance of drug resistance amongst children presenting with culture-confirmed tuberculosis to a tertiary care hospital and to community clinics. Methods: Drug susceptibility testing for isoniazid and ...
Ethionamide cross-and co-resistance in children with isoniazid-resistant tuberculosis
(2009)
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 ...
Minimal inhibitory concentration of isoniazid in isoniazid-resistant Mycobacterium tuberculosis isolates from children
(2006)
The aim of the study presented here was to determine the minimal inhibitory concentration of isoniazid for strains of isoniazid-resistant or multidrug-resistant Mycobacterium tuberculosis isolated from children in the ...
Cavitation of the Ghon focus in an HIV-infected infant who acquired tuberculosis after the initiation of HAART
(2009)
Tuberculosis immune reconstitution inflammatory syndrome (IRIS) may present as new or worsening cavitation. We present an HIV-infected infant in whom TB infection and subsequent cavitation of the Ghon focus appeared to ...
Multidrug-resistant and extensively drug-resistant tuberculosis: a threat to global control of tuberculosis
(2010)
Although progress has been made to reduce global incidence of drug-susceptible tuberculosis, the emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis during the past decade threatens to ...
