- グループ間のサイトカイン濃度の比較:重度の急性喘息,軽度の喘息,慢性喘息,および健康な対照群.
- ステロイド治療を受けている重度の喘息患者のsIL-2Rレベルを連続的にモニターした.
主要な成果:
- 濃度 (GM-CSF) は,重度の喘息患者において,健康な対照群と比較して,著しく高かった.
- プラズマのsIL-2R濃度は,健康な個人と比較して,すべての喘息群で上昇したが,喘息の重症度レベルによって違いはなかった.
- ステロイド治療の7日後にsIL-2R濃度が大幅に低下したが,この変化はピーク排気流の臨床改善と相関していなかった.
結論:
- この研究は,喘息におけるTリンパ球の活性化を確認している.
- プラズマのsIL-2Rは,喘息疾患の活性をモニタリングしたり,治療の有効性を予測したりするための,敏感で信頼性の高いバイオマーカーではありません.

Inflammation
Overview
Inflammatory Response I: Vascular and Cellular
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...
Inflammatory Response
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Acute Respiratory Failure-V
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

Acute Inflammation I: Inflammatory Response
Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Acute Inflammation II: Cellular Phase
The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
