Biomarker research characterising the effect of anti-tuberculosis (TB) chemotherapy on systemic body response is still limited. In this study, we aimed to investigate fluctuations in circulating cell-free mitochondrial DNA (ccf-mtDNA) and circulating cell-free nuclear DNA (ccf-nDNA) copy number (CN) in blood plasma of patients with drug-susceptible TB (DS-TB) and to decipher factors related to these fluctuations. The results showed considerable changes in ccf-mtDNA CN in plasma samples before drug intake and 2 and 6 h afterwards, with high inter patient variability at each time point.

Ototoxicity is a significant adverse effect associated with second-line anti-tuberculosis (TB) medications, particularly in treating extensively drug-resistant TB (XDR-TB). This study investigated the awareness of ototoxic effects among adults with XDR-TB undergoing treatment in South Africa, specifically exploring the role of information counselling on ototoxic symptoms, the timing of counselling, the content covered, and the management pathways available. This cross-sectional, descriptive qualitative study was conducted at Brooklyn Chest Hospital in the Western Cape.

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remains a significant global public health issue with high mortality rates and challenges posed by drug-resistant strains, emphasizing the continued need for new therapeutic targets and effective treatment strategies. Transcriptomics is a highly effective tool for the development of novel anti-tuberculosis drugs. However, most studies focus only on changes in gene expression levels at specific time points.

Hepatic tuberculosis, typically associated with miliary tuberculosis, can occasionally present as localized liver lesions. This case report describes a 77-year-old male presenting with persistent abdominal pain and fever, following an endoscopic retrograde cholangiopancreatography for bile duct sludge removal. Subsequent computed tomography revealed focal liver lesions.

Tuberculosis (TB) is one of the leading causes of death in the world, despite being a preventable and curable disease. Irrespective of tremendous advancements in early detection and treatment, this disease still has high mortality rates. This is due to the development of antibiotic resistance, which significantly reduced the efficacy of antibiotics, rendering them useless against this bacterial infection.
