Value of different staging systems for predicting neurological outcome in childhood tuberculous meningitis
BACKGROUND: The stage of tuberculous meningitis (TBM) at presentation is strongly associated with prognosis. OBJECTIVE: To compare different staging systems for TBM in predicting outcome. METHODS: The associations of ...
Evaluating the BED capture enzyme immunoassay to estimate HIV incidence among adults in three countries in sub-Saharan Africa
Serological assays for estimating HIV-1 incidence are prone to misclassification, limiting the accuracy of the incidence estimate. Adjustment factors have been developed and recommended for estimating assay-based HIV-1 ...
High prevalence of drug resistance amongst HIV-exposed and -infected children in a tuberculosis prevention trial
An emergence of drug-resistant tuberculosis (DR-TB) in settings affected by human immunodeficiency virus (HIV) and tuberculosis (TB) has been observed. We investigated the prevalence of DR-TB in P1041, a multicentred, ...
The potential to transmit Mycobacterium tuberculosis at a South African tertiary teaching hospital.
OBJECTIVES: To assess the risk of nosocomial transmission by confirmed pulmonary tuberculosis (PTB) patients in a high TB/HIV incidence environment. METHODS: Between November 2006 and April 2007, we carried out a cross-sectional ...
Interferon-gamma release assays for the detection of Mycobacterium tuberculosis infection in children with cancer
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 ...
Early mortality and loss to follow-up in HIV-infected children starting antiretroviral therapy in Southern Africa
Background: Many HIV-infected children in Southern Africa have been started on antiretroviral therapy (ART), but loss to follow up (LTFU) can be substantial. We analyzed mortality in children retained in care and in all ...
Virologic failure and second-line antiretroviral therapy in children in South Africa-the IeDEA Southern Africa collaboration
Background: With expanding pediatric antiretroviral therapy (ART) access, children will begin to experience treatment failure and require second-line therapy. We evaluated the probability and determinants of virologic ...
Pyridoxal-5-phosphate plasma concentrations in children receiving tuberculosis chemotherapy including isoniazid
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, ...
Radiological changes post-lymph node enucleation for airway obstruction in children with pulmonary tuberculosis
Background: Tuberculous lymphadenopathy causing airway obstruction in children may be life threatening and may require surgical enucleation of the lymph glands. There are no studies investigating the radiological picture ...
