Published on: July 19, 2007
まとめ
テタノス・トキソイド (TT) 皮膚検査は,カンジダ菌またはマムプス・アンチゲンよりも細胞免疫を評価するのに効果が低い. しかし,TTの皮膚検査は,高齢の成人では,不十分な破傷腫予防接種を示唆する可能性があります.
科学分野:
- 免疫学 免疫学とは
- 感染症 感染症とは
背景:
- 細胞の免疫機能は,さまざまな健康状態の診断と管理に不可欠です.
- 標準的な皮膚検査のアンチゲンであるカンジダ菌やマムプスは,細胞免疫を評価するために一般的に使用されます.
- 免疫評価のための皮膚検査抗原としてのテタヌス毒素 (TT) の有用性は,さらなる調査を必要としています.
研究 の 目的:
- 住院患者における細胞免疫機能を評価するための皮膚検査抗原としてのテタヌストキソイド (TT) の有効性を評価する.
- TTの応答率を他の一般的な皮膚検査抗原 (カンジダ,マムプス,PPD) と比較する.
- TT皮膚検査の反応と,年齢などの患者の人口統計の相関を調査する.
主な方法:
- 入院した患者は,四つの抗原 (テタヌス・トキソイド (TT),カンジダ,マムプス,浄化タンパク質誘導体 (PPD) の皮膚検査を受けた.
- 各抗原に対する応答率を記録し,比較した.
- 患者の年齢と予防接種歴が分析に考慮された.
主要な成果:
- カンジダとマップス抗原は,TTとPPDと比較して,著しく高い陽性反応率を誘発しました.
- TT皮膚検査の応答率の顕著な低下は,高齢の患者で観察されました.
- 一部の患者は,他の一般的な抗原に対して否定的な反応を示しながら,TT反応が陽性であった.
結論:
- テタヌストキソイド (TT) は,入院患者における細胞免疫機能の評価において,カンジダまたはマムプス抗原よりも効果が低い.
- 高齢者のTTに対する反応の低下は,デタックスワクチン接種における潜在的なギャップを示唆しています.
- TT皮膚検査は,免疫状態とエネルギーレベルに関する洞察を提供し,予防接種後の陰性から陽性への変換の可能性があります.

Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Tetanus
Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
