Role of rpsA Gene Sequencing in Diagnosis of Pyrazinamide Resistance [PDF]

Journal of Clinical Microbiology, 2013
We read with great interest the article by Alexander and colleagues ([1][1]) on the frequency of rpsA mutations in pyrazinamide-susceptible and resistant isolates with a wild-type pncA gene. In contrast to the report of Shi and colleagues ([2][2]), Alexander and colleagues could not find any ...

Characterization of pyrazinamide resistance in consecutive multidrug-resistant mycobacterium tuberculosis isolates in sweden between 2003 and 2015

International Journal of Mycobacteriology, 2017
Background: The first line anti-tuberculosis drug pyrazinamide (PZA) is important when treating PZA susceptible multidrug-resistant tuberculosis (MDR-TB). Several drug resistance surveys have however reported PZA resistance among a significant proportion

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.

Molecular investigation against the resistant mechanism of PncA mutated pyrazinamide resistance and insight into the role of pH environment for pyrazinamide activation

Journal of Biomolecular Structure and Dynamics, 2019
Pyrazinamide (PZA), a crucial component of anti-TB therapy, is a prodrug. PZA interacts with PncA protein to be converted into its functional form i.e. pyrazinoic acid (POA). It has unique feature to kill dormant tubercle bacilli of acidic environment.

The Patterns of Conversion to Anti-Tuberculosis Drug Resistance in Mycobacterium tuberculosis

Korean Journal of Clinical Laboratory Science, 2022
The prevalence of multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) are increasing. We analyzed the patterns of drug resistance and tracking period days of acquiring anti-mycobacterial resistance.

Altered Pharmacokinetics and Delayed Sputum Conversion in Tuberculosis Patients Co‐Infected With HIV

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background HIV co‐infection affects host responses and pharmacokinetics (PK) of tuberculosis (TB) treatment. This study assessed the PK of first‐line anti‐TB drugs and clinical outcomes in patients with and without HIV co‐infection. Methods In this prospective observational study, 61 adults with sputum‐positive pulmonary TB, either confirmed ...

Adverse events in bedaquiline‐ and pretomanid‐based regimens for drug‐resistant tuberculosis from trial, implementation and pharmacovigilance studies

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2607-2623, August 2026.
Abstract The availability of safety data, particularly concerning adverse events (AEs) associated with the new shorter regimen for drug‐resistant tuberculosis (TB) containing a bedaquiline–pretomanid‐based regimen, is still limited. This systematic review aims to provide a comprehensive and updated analysis of AEs related to this new regimen by ...

Resistance patterns of Mycobacterium tuberculosis isolates from pulmonary tuberculosis patients in Nairobi

Journal of Infection in Developing Countries, 2011
Introduction: In Kenya, which ranks thirteenth of 27 high tuberculosis burden countries, diagnosis is based on Ziehl-Neelsen staining alone and patients are treated without information on sensitivity patterns.

Preserved Spermatogenesis and Hormonal Function in Men Receiving a Pretomanid Regimen (BPaMZ) for Pulmonary Drug‐Resistant Tuberculosis

Clinical Pharmacology &Therapeutics, Volume 120, Issue 2, Page 501-509, August 2026.
Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...
