In the battle against tuberculosis (TB), plasticity of the
Mycobacterium tuberculosis
genome is believed to contribute to the pathogen’s virulence and drug resistance. Here, we report 10 draft genome sequences of clinical
M. tuberculosis
isolated in Malaysia as the basis for understanding the genome plasticity of the
M. tuberculosis
isolates.
Background: Currently multidrug-resistant tuberculosis (MDR-TB) poses a signi cant public health concern in Malaysia.Objective: This study is aimed to evaluate the prevalence of MDR-TB in Malaysian tuberculosis patients. Method. A retrospective analysis was performed, and data was obtained from the Malaysian National TB Information System (TBIS) between 2009 and 2019. A record of 989 MDR-TB cases were identi ed and associated risk characteristics such as marital status, gender, ethnicity, employment status, alcohol consumption, diabetic status and smoking status were determined. The statistical analysis was performed using the SPSS software version 20.Results: Overall, the occurrence of MDR-TB among patients with TB infections in Malaysia was 0.34% based on data collected from TBIS. The ndings revealed major variations in the incidence of MDR-TB between male and female patients (0.44%, 0.20%, p < 0.001), single and married patients (1.63% vs 0.24%, p < 0.001), ethnicity (p < 0.001), working and non-working patients (0.48% vs 0.32%, p < 0.001), alcoholic and non-alcoholic patients (0.44% vs 0.32%, p < 0.001), diabetic patients and non-diabetic patients (0.39% vs 0.27%, p < 0.001), followed by smoking and non-smoking patients (0.13% vs 0.27%, p < 0.001).
Conclusion:This study provides a substantial assessment of MDR-TB prevalence and associated risk factors that could be useful for the implementation of new strategies in Malaysia's national TB policy.
Aim: Hepatotoxicity is a known adverse effect of antituberculosis drugs. The NAT2 gene polymorphism has been associated with an increased risk of antituberculosis drug-induced hepatotoxicity (ATDIH). Materials and methods: This study investigates the association of NAT2 polymorphism and clinical risk factors that may contribute to the development of ATDIH. The authors sequenced the NAT2 region of 33 tuberculosis patients who developed ATDIH and 100 tuberculosis patients who did not develop ATDIH during tuberculosis treatment. NAT2 haplotypes were inferred and NAT2 acetylator status was predicted from the combination of the inferred haplotypes. Multiple logistic regression was performed to identify possible factors that are associated with ATDIH. Results: The TT genotype of NAT2*13A and the AA genotype of NAT2*6B were found to be substantially linked with the risk of ATDIH, with odds ratios of 3.09 (95% CI: 1.37–6.95) and 3.07 (95% CI: 1.23–7.69), respectively. NAT2 slow acetylators are 3.39-times more likely to develop ATDIH. Factors that were associated with ATDIH include underlying diabetes mellitus (adjusted odds ratio [AOR] 2.96; 95% CI: 1.05–8.37), pre-treatment serum bilirubin (AOR 1.09; 95% CI: 1.02–1.16) and NAT2 slow acetylator (AOR 3.77; 95% CI: 1.51–9.44). Conclusion: Underlying diabetes mellitus, having a higher baseline bilirubin and being a slow acetylator are identified as the risk factors associated with ATDIH among patients in Malaysia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
