まとめ
COVID-19は,HAEの病理生理学と同様に,ブラジキニンのレベルを増やすことで,遺伝性血管腫 (HAE) の発作を引き起こす可能性があります. この症例報告は,COVID-19を小児患者の潜在的HAEトリガーとして認識することの重要性を強調しています.
科学分野:
- 免疫学
- ウイルス学
- 小児科
背景:
- 遺伝性血管腫 (HAE) は,ブラジキニンの蓄積による再発性腫を引き起こす珍しい遺伝疾患です.
- SARS-CoV-2感染は,HAEの病理生理学を模倣して,ACE2によるブラジキニンの分解を阻害する.
- COVID-19は成人におけるHAEの悪化と関連付けられていますが,小児の症例はまれです.
研究 の 目的:
- COVID-19によって引き起こされた発作を経験した小児HAE患者の最初の詳細な症例を報告する.
- 子どもにおける潜在的HAEトリガーの1つとして,COVID-19に対する意識を高めること.
- パンデミックの間,小児のHAE発症管理教育の必要性を強調する.
主な方法:
- HAEと診断された小児患者の症例報告
- SARS-CoV-2 感染後の症状の進行と治療のタイムラインの文書化.
- ブラジキニンとACE2の共有病理学的経路のレビュー
主要な成果:
- HAEの小児患者は,COVID-19に感染した後に発作を経験しました.
- フレアのメカニズムは,HAEと一致するSARS-CoV-2誘発のブラジキニン不調を含んでいる.
- この症例は,COVID-19の小児HAE患者の症状発現と管理の詳細なタイムラインを提供します.
結論:
- COVID-19は小児集団におけるHAE発症の重要な引き金となる可能性があります.
- 保健医療提供者は,小児性HAE患者の家族にCOVID-19に関連する発症準備について教育すべきである.
- 継続的な警戒と意識は,SARS-CoV-2の世界的な拡散を考慮して極めて重要です.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
451
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma: Pathogenesis and Management
576
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Allergic Drug Reactions
972
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Nephrotic Syndrome II : Assessment and Medical Management
21
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...
