NAT2 rapid acetylator status and other risk factors associated with isoniazid mono-resistance among Thai pulmonary tuberculosis patients of central chest institute of Thailand
NAT2 rapid acetylator status และปัจจัยเสี่ยงอื่น ๆ ที่สัมพันธ์กับการดื้อยาไอโซไนอาซิดในผู้ป่วยวัณโรคปอดชาวไทยของสถาบันโรคทรวงอก
Abstract:
The purpose of this study was to investigate the risk factors of isoniazid monoresistance among Thai pulmonary tuberculosis patients of Central Chest Institute of Thailand. Data were collected from interview, medical record review, and saliva sample collection from 18th September 2017 to 20th February 2018. The total number of participants was 167, comprising 50 isoniazid mono-resistant (cases) and 117 drug susceptible tuberculosis (controls) patients. Descriptive statistics, Chi-squared test, and multivariate logistic regression analysis were used for data analysis. The results showed that rapid acetylator was less likely to develop isoniazid monoresistance compared with slow acetylator (OR 1.169; 95% CI 0.435-3.140), even though the percentage of rapid acetylators which resisted to only isoniazid (16.0%) was higher than that of controls (14.5%). In contrast, the highest percentage of NAT2 phenotype among cases was slow acetylator status (44.0%), whereas that of controls was intermediate acetylator status (51.3%). However, NAT2 *4/*6A was mostly found in both cases (24.0%) and controls (32.5%). In addition, adults who were less than 50 years old were more likely to have isoniazid mono-resistance (aOR 2.281; 95% CI 1.101 - 4.728) than elders who were more than 50 years old. Due to the fact that the number of the studies associated with risk factors of isoniazid mono-resistance among Thai TB patients was less, the researchers should be encouraged to do more similar research to prevent this situation in Thailand.
