概括
超免疫静脉免疫球蛋白 (hIVIG) 没有改善住院COVID-19患者的结果. 根据先前存在的抗体,安全性有所不同,抗体阳性患者的风险增加.
科学领域:
- 免疫学
- 传染性疾病
- 临床试验
背景情况:
- 从康复的捐赠者获得的高免疫静脉免疫球蛋白 (hIVIG) 是一种潜在的SARS-CoV-2治疗方法.
- 对于hIVIG在COVID-19治疗中的随机临床试验数据有限.
研究的目的:
- 在住院的COVID-19患者中评估hIVIG与安慰剂的疗效和安全性.
- 根据顺序终点和复合安全措施评估结果.
主要方法:
- 一项国际,随机,双盲,安慰剂控制的试验,涉及593名住院的COVID-19患者.
- 患者接受了hIVIG或安慰剂,同时接受了标准治疗,包括remdesivir.
- 在第七天使用七类顺序终点测量主要结果;在第七天和第28天通过复合结果评估安全性.
主要成果:
- 与安慰剂相比,hIVIG在第7天没有显著提高更有利结果的几率 (OR1. 06, p=0. 72).
- 输液反应在hIVIG治疗中更为常见 (18. 6% vs 9. 5%).
- 综合安全结果相似,但观察到异质性:抗体阳性患者的风险增加 (OR 2.21) 和抗体阴性患者的风险降低 (OR 0.51).
结论:
- 在没有终端器官衰竭的情况下,在住院的COVID-19患者中,SARS-CoV-2 hIVIG在标准护理下没有显示出有效性.
- 根据基线内源性中和抗体的存在,hIVIG的安全性可能有所不同.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
755
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 Biologic Agents: Anti-TNF
880
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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
692
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...

Bioavailability Study Design: Healthy Subjects Versus Patients
248
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Myocarditis III: Medical Management
343
Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Acute Coronary Syndrome III: Diagnostic Studies
495
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
