概括
皮下 (SC) 甲状腺素 (MTX) 与口服 (PO) MTX相比,可能为早期类风湿性关节炎 (RA) 患者提供更好的结果. 这项现实研究表明,SC MTX可能会在两年内改善疾病活动和疼痛管理.
科学领域:
- 类风湿病学 类风湿病学
- 药理学 药理学 是一个学科.
- 临床研究 临床研究
背景情况:
- 早期类风湿性关节炎 (RA) 需要迅速有效的治疗策略.
- 甲托雷克萨特 (MTX) 是一种治疗RA的基石,可用于皮下 (SC) 和口腔 (PO) 配方.
- 了解初始SC与PO MTX在现实环境中的比较有效性对于优化患者护理至关重要.
研究的目的:
- 在早期的RA患者中比较两年来疾病活动和疼痛轨迹,开始SC或PO甲索特雷克萨.
- 分析治疗失败,定义为对生物DMARDs (bDMARDs) 的需求,以及MTX配方的药物存活率.
- 在早期的RA中提供关于使用SC与PO甲索特雷克萨特初始治疗策略的现实世界的证据.
主要方法:
- 来自芬兰登记的4655名早期RA患者的回顾性分析 (1.1.201631.12.2023).
- 利用局部估计的散射图平滑 (LOESS) 来检测疾病活动和疼痛轨迹.
- 根据年龄和性别调整的考克斯回归分析,以评估治疗失败 (避免bDMARDs) 并计算两年后的MTX购买比例.
主要成果:
- 与POMTX (n=3579) 相比,开始SCMTX的患者 (n=1076) 在两年内显示出更有利的疾病活动和疼痛轨迹.
- 避免bDMARDs的概率在SC MTX启动器 (0.87) 与PO MTX启动器 (0.91) 中较高,尽管PO显示避免bDMARDs的概率略高 (p<0.001).
- 两年后的MTX购买率在两组中都是相似的 (SC的80%对PO的79%).
结论:
- 作为早期类风湿性关节炎的第一个治疗策略的一部分,开始皮下注射甲状腺素可能会导致两年内比口服甲状腺素更有利的疾病活性和疼痛结果.
- 这种现实世界的证据支持将SC MTX视为管理早期RA的潜在更有效的初始选择.
- 进一步的研究可以探索与SC相比PO MTX在RA治疗中的长期结果和患者报告的益处.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
447
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Therapeutic Drug Monitoring: Affecting Factors
163
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Drug Delivery: Miscellaneous Routes
690
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Dosage Interval and Administration Route: Determination Methods
187
A medication’s effectiveness largely depends on its appropriate dosage and the route of administration. Dosage ensures that a sufficient drug concentration is maintained in the bloodstream to elicit the desired therapeutic effect without causing toxicity. The route of administration affects the drug's bioavailability, rate of absorption, and onset of action, which are crucial for achieving optimal therapeutic outcomes. Drug dosage calculations are critical to tailoring therapy to...

Additional Routes of Drug Administration
4.6K
Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Factors Affecting Drug Response: Overview
2.8K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
