概括
在患有稳定儿科非传染性脑膜炎 (PNIU) 的儿童中减少或停止阿达利穆马布 (ADA) 导致炎症复发的高风险. 在最后有效剂量频率下恢复ADA有助于恢复疾病控制.
科学领域:
- 眼科医生 眼科 眼科
- 免疫学 免疫学 免疫学
- 儿科 儿科 儿科
背景情况:
- 儿科非传染性脑膜炎 (PNIU) 需要长期治疗,通常使用生物药物,如阿达利姆巴 (ADA).
- 优化ADA治疗策略,包括剂量减少和戒断,对于儿童的PNIU管理至关重要,同时最大限度地降低治疗负担和潜在的副作用.
研究的目的:
- 评估在患有稳定PNIU的儿童中降低阿达利穆马布剂量和戒断策略的可行性和结果.
- 评估炎症复发的风险和在剂量修改或停止后恢复ADA治疗的有效性.
主要方法:
- 一个开放标签的前性试验试验,涉及18名稳定的PNIU患者 (2-18岁) 接受ADA和甲醇治疗.
- 患者最初的ADA间隔从2周延长到4周,然后如果稳定,则完全停药,随访48周.
- 关键结局包括无复发的生存率,视力敏度,眼睛炎症标志物 (前腔细胞,视炎),黄斑厚度和血清ADA水平.
主要成果:
- 观察到显著的复发率:剂量减少期间33.3% (每4周一次ADA) 和戒断后44.5%.
- 在48周内,只有22.2%的患者没有复发;在4名患者中成功退出治疗,所有患者都被诊断为贝塞特病 (BD).
- 虽然视力敏度和黄斑厚度保持稳定,但眼睛炎症标志物 (前腔细胞,视炎) 呈现上升趋势;血清ADA水平随着时间的推移而下降.
结论:
- 在稳定的PNIU患者中,降低和取消阿达利穆马布的剂量会带来复发炎症的高风险.
- 在最后有效剂量频率恢复阿达利穆马布可以有效控制炎症.
- 在出现复发的患者中监测血清ADA水平可能有助于确定最佳剂量间隔.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
160
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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
116
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
134
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Rational Dosage Regimen: Maintenance Dose and Loading Dose
4.0K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Renal Failure: Dose Adjustments
88
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

Inflammatory Bowel Disease IV: Pharmacological Management
127
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
