研究目的: |
已知不同的结核病患者体内异烟肼(INH)代谢速度存在明显差异,但目前未针对不同代谢类型患者采用针对性剂量,无法最优化INH的抗结核效果。本研究以NAT2基因型差异为抓手,以监测患者痰中结核菌的下降速度作为评价指标,通过增加快乙酰化型(RA)和中间乙酰化型结核病患者的INH剂量,观察调整异烟肼剂量能否缩短患者痰菌阴转时间。研究目是为临床依据不同结核病患者的乙酰化类型指导个体选择安全、高效的异烟肼剂量提供参考依据。 |

Objectives of Study: |
It is known that there are significant differences in the metabolism rate of isoniazid (INH) among different tuberculosis patients. However, currently, targeted dosages are not used for patients with different metabolic types, so it is impossible to optimize the anti - tuberculosis effect of INH. This study takes the differences in NAT2 genotypes as a starting point and monitors the decline rate of Mycobacterium tuberculosis in patients' sputum as an evaluation index. By increasing the INH dosage for patients with rapid acetylator (RA) and intermediate acetylator types of tuberculosis, it observes whether adjusting the isoniazid dosage can shorten the time for sputum smear conversion in patients. The research aim is to provide a reference basis for clinically guiding individuals to select safe and efficient isoniazid dosages according to the acetylation types of different tuberculosis patients. |

|
药物成份或治疗方案详述: |
1、应用NAT2基因多态性检测试剂盒检测异烟肼乙酰化代谢类型。对比分析不同乙酰化型的初治敏感菌阳肺结核患者在使用含标准剂量INH的治疗方案时痰标本中细菌载量的变化及实现痰菌阴转所需时间,评估NAT2基因型与对患者痰菌阴转时间的影响。 2、评估与含标准化INH剂量的一线抗结核方案相比,增加INH用量对IA和RA型患者痰标本中细菌载量下降速度的影响,以及最终痰菌转阴所需时间跨度的影响,进而评估依据NAT2基因型调整异烟肼剂量对缩短患者传染时间的影响及剂量调整的安全性。以此探讨IA和RA型患者最佳异烟肼用量。 |

|
Description for medicine or protocol of treatment in detail: |
1. Use the NAT2 gene polymorphism detection kit to detect the isoniazid acetylation metabolic type. Compare and analyze the changes in the bacterial load in the sputum specimens of newly - treated smear - positive pulmonary tuberculosis patients with sensitive bacteria of different acetylation types when using a treatment regimen containing a standard dose of INH, and the time required to achieve sputum smear conversion. Evaluate the influence of the NAT2 genotype on the sputum smear conversion time of patients. 2. Evaluate the impact of increasing the INH dosage on the decline rate of the bacterial load in the sputum specimens of patients with IA and RA types, as well as the impact on the time span required for final sputum smear conversion, compared with the first - line anti - tuberculosis regimen containing a standard INH dose. Then, evaluate the influence of adjusting the isoniazid dosage according to the NAT2 genotype on shortening the infectious period of patients and the safety of the dosage adjustment. Based on this, explore the optimal isoniazid dosage for patients with IA and RA types. |
