まとめ
腫瘍死因アルファ (TNF-α) レベルは,関節リウマチ (RA) 患者と症患者との比較が可能です. これは,TNF-αがRAにおける役割にもかかわらず,セプシスの主要な要因ではないことを示唆しています.
科学分野:
- 免疫学
- リウマトロジ
- クリティカル ケア 医療
背景:
- 腫瘍死因アルファ (TNF-α) は,リウマチ性関節炎 (RA) などの炎症性および自己免疫疾患における重要なサイトカインです.
- 抗TNF-α治療はRAでは有効ですが,セプシスでは効果が証明されていません.
- セプシスの病原性におけるTNF-αの役割は不明である.
研究 の 目的:
- RA患者の循環中のTNF-αレベルを定量化するために.
- TNF-αレベルをRAとセプシスで比較する.
- 抗TNFα治療の臨床的影響を調査する.
主な方法:
- ランダム化制御試験と観察研究の体系的レビューとメタ分析.
- 複数のデータベース (Cochrane,Embase,MEDLINEなど) で検索 2023年5月まで
- ランダム効果モデルを用いて,血清/血TNFαの平均を抽出して分析した.
主要な成果:
- 5399人の参加者を含む104件の研究で,RA TNF-αの総平均値は23.1ppg/mlでした.
- DMARD (p=0. 04) とコルチコステロイド (p=0. 01) を使用したRA患者で観察されたTNF-αの低下.
- 調整されたTNF-αレベルは,RAではセプシスと有意に異なるものではありませんでした.
結論:
- 循環中のTNF-αレベルは,RAとセプシス患者の間で,調整後に比較可能である.
- 類似のTNF-α濃度にもかかわらず,RAにおける抗TNF-α療法の有効性は,TNF-αが主な症の要因ではないことを示唆している.
- 研究の異質性は,TNF-α濃度のわずかな変動に寄与する可能性があります.

T Cell Types and Functions
1.4K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
54
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...

The JAK-STAT Signaling Pathway
9.2K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Rheumatic Heart Disease I: Introduction
38
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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
230
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...
