概括
在类风湿性关节炎中,瑞图西马布 (RTX) 治疗在几个月内显著降低了乙型肝炎表面抗体 (抗HBs) 标位. 较低的基线抗HBs和类固醇使用增加了保护的丧失,需要监测.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 药理学 药理学是指药理学的学科.
背景情况:
- 里图西马布 (RTX) 用于类风湿性关节炎 (RA).
- RTX会影响B细胞,可能会影响抗体标位.
- 在接受RTX治疗的RA患者中,长度抗HBs标位和血清保护并未得到很好的定义.
研究的目的:
- 评估接受RTX的RA患者抗HBs标位的纵向变化.
- 为了确定RTX治疗期间血清保护损失的决定因素.
主要方法:
- 在RTX的RA患者中对抗HBs标位的长度研究.
- 统计分析包括弗里德曼,威尔科克森签名等级,麦克纳马的测试,斯皮尔曼相关性和多变量后勤回归.
- 分析用SPSS进行,并用Python进行交叉验证.
主要成果:
- 抗HBs标位在RTX开始后3个月内急剧下降 (463.2至218.3 IU/L),并持续下降至6个月.
- 在12-24个月后,标位趋于平稳 (119.3 IU/L).
- 较低的基线抗HBs (OR 0.65) 和皮质类固醇使用 (OR 1.94) 预测了保护的丧失;较高的IgG是保护性的 (OR 0.72).
结论:
- 在RA患者中,RTX疗法导致抗HBs标位的显著,时间依赖的减少.
- 基线抗HBs标位和同时使用类固醇是失去血清保护的关键风险因素.
- 建议进行治疗前查,潜在的补丁疫苗接种和监测.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
460
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic Heart Disease I: Introduction
415
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease III: Medical Management
268
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
465
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 Immunomodulatory Agents
469
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...
