A semi-automatic technique to quantify complex tuberculous lung lesions on 18F-fluorodeoxyglucose positron emission tomography/computerised tomography images

Author: Malherbe, Stephanus T ; Dupont, Patrick ; Kant, Ilse ; Ahlers, Petri ; Kriel, Magdalena ; Loxton, André G ; Chen, Ray Y ; Via, Laura E ; Thienemann, Friedrich ; Wilkinson, Robert J ; Barry, Clifton E ; Griffith-Richards, Stephanie ; Ellman, Annare ; Ronacher, Katharina ; Winter, Jill ; Walzl, Gerhard ; Warwick, James M Date: 25 Jun 2018 Background There is a growing interest in the use of 18F-FDG PET-CT to monitor tuberculosis (TB) treatment response. However, TB causes complex and widespread pathology, which is challenging to segment and quantify in a ... Read more
Bacterial loads measured by the Xpert MTB/RIF assay as markers of culture conversion and bacteriological cure in pulmonary TB

Author: Shenai, Shubhada ; Ronacher, Katharina ; Malherbe, Stefanus ; Stanley, Kim ; Kriel, Magdalena ; Winter, Jill ; Peppard, Thomas ; Barry, Charles E ; Wang, Jing ; Dodd, Lori E ; Via, Laura E ; Walzl, Gerhard ; Alland, David Date: 2016 Introduction Biomarkers are needed to monitor tuberculosis (TB) treatment and predict treatment outcomes. We evaluated the Xpert MTB/RIF (Xpert) assay as a biomarker for TB treatment during and at the end of the 24 weeks therapy. METHODS: ... Read more c b
Baseline Predictors of Sputum Culture Conversion in Pulmonary Tuberculosis: Importance of Cavities, Smoking, Time to Detection and W-Beijing Genotype

Author: Visser, Marianne E ; Stead, Michael C ; Walzl, Gerhard ; Warren, Rob ; Schomaker, Michael ; Grewal, Harleen M S ; Swart, Elizabeth C ; Maartens, Gary Date: 2012 BACKGROUND: Time to detection (TTD) on automated liquid mycobacterial cultures is an emerging biomarker of tuberculosis outcomes. The M. tuberculosis W-Beijing genotype is spreading globally, indicating a selective advantage. There is a paucity ... Read more c b
Effect of standard tuberculosis treatment on plasma cytokine levels in patients with active pulmonary tuberculosis

Author: Riou, Catherine ; Peixoto, Blas Perez ; Roberts, Lindi ; Ronacher, Katharina ; Walzl, Gerhard ; Manca, Claudia ; Rustomjee, Roxana ; Mthiyane, Thuli ; Fallows, Dorothy ; Gray, Clive M Date: 2012 BACKGROUND: Sputum Mycobacterium tuberculosis (Mtb) culture is commonly used to assess response to antibiotic treatment in individuals with pulmonary tuberculosis (TB). Such techniques are constrained by the slow growth rate of Mtb, and more ... Read more c b
Quantitative 18F-FDG PET-CT scan characteristics correlate with tuberculosis treatment response

Author: Malherbe, Stephanus T ; Chen, Ray Y ; Dupont, Patrick ; Kant, Ilse ; Kriel, Magdalena ; Loxton, André G ; Smith, Bronwyn ; Beltran, Caroline G G ; van Zyl, Susan ; McAnda, Shirely ; Abrahams, Charmaine ; Maasdorp, Elizna ; Doruyter, Alex ; Via, Laura E ; Barry, Clifton E ; Alland, David ; Richards, Stephanie G ; Ellman, Annare ; Peppard, Thomas ; Belisle, John ; Tromp, Gerard ; Ronacher, Katharina ; Warwick, James M ; Winter, Jill ; Walzl, Gerhard Date: 10 Feb 2020 Abstract Background There is a growing interest in the use of F-18 FDG PET-CT to monitor tuberculosis (TB) treatment response. Tuberculosis lung lesions are often complex and diffuse, with ... Read more c b
