概括
贝达基林 (BDQ) 可以导致多耐药结核病 (MDR-TB) 患者的QTc延长,但需要改变治疗的严重病例很少见. 定期进行心脏监测,特别是在前三个月,对于在治疗MDR-TB时安全使用BDQ至关重要.
科学领域:
- 心脏病学 心脏病学
- 传染性疾病 传染性疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 贝达奎林 (BDQ) 是治疗多抗药结核病 (MDR-TB) 的重要药物,特别是在印度.
- 潜在的心脏毒性,特别是QTc延长,需要对接受BDQ的患者进行仔细监测.
- 由于遗传和环境变异性,印度患者BDQ诱导的QTc延长的本地数据至关重要.
研究的目的:
- 评估Bedaquiline相关的QTc延长的患病率,严重程度和危险因素,在印度患者中,MDR/Rifampicin-resistant (RR) -TB.
- 提供本地证据,以指导在高MDR-TB负担人口中安全使用Bedaquiline.
主要方法:
- 一项涉及55名RR/MDR-TB成年患者的前性分析研究,该研究始于含BDQ的治疗方案.
- 电心电图 (ECG) 在基线,1,3,6个月进行,QTc间隔用弗里德里西亚公式计算.
- 显著的QTc延长被定义为QTcF≥500毫秒或与基线≥60毫秒的变化.
主要成果:
- 整体QTc延长的流行率为37.25%,其中13.7%经历了显著的延长.
- 中度至严重的QTc延长在3个月的时间最常见.
- 男性性别和BMI>18.5kg/m2被确定为显著的危险因素;具有显著的QTc延长的患者年龄在60岁以下.
结论:
- 在BDQ治疗的MDR/RR-TB患者中,QTc延长是常见的,但需要修改治疗的严重病例并不常见.
- 对于MDR-TB的管理,BDQ仍然至关重要,这强调了需要勤奋地进行心脏监测,特别是在最初的三个月.
- 建议进行进一步的大规模研究,以验证发现并确定额外的风险因素,考虑到研究的局限性,例如样本大小和同时服用的药物.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Pharmacokinetic–Pharmacodynamic Relationship: Influence of Elimination Half-Life on Effect Duration
70
Drug elimination from the body primarily occurs through metabolic and excretion pathways. Hepatic metabolism transforms lipophilic drugs into hydrophilic forms for excretion, typically via enzymatic processes classified as phase I (modification) and phase II (conjugation). Renal excretion eliminates drugs and metabolites through filtration and secretion in the kidneys. Impairment in liver or kidney function can hinder these processes, delaying drug clearance and extending the drug’s...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
324
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Pharmacokinetic–Pharmacodynamic Relationship: Duration of Dose-Effect Relationship
75
For drugs producing a quantal response, onset occurs when plasma concentration reaches a minimum effective level (Cmin). The drug's action duration depends on how long the plasma concentration remains above Cmin.Two primary factors influence this duration: dose size and the rate of drug removal from the action site. Both depend on the drug's redistribution to poorly perfused tissues and elimination processes. A larger dose promotes rapid onset and prolongs the effect's duration.Consider a...
