COVID-19以降の普遍性脱毛症:自己免疫性脱毛症と再発管理の課題
Journal of drugs in dermatology : JDD
|September 5, 2025
まとめ
COVID-19は,急激な脱毛につながるアルペシア・エリアタの一種である重度のアルペシア・ユニバーサル (AU) を引き起こす可能性があります. このケースは,ウイルスの後に再発する性質を強調し,新しい長期的な管理戦略を必要とします.
科学分野:
- 皮膚科
- 免疫学
- ウイルス学
背景:
- アロペシア・ユニバーサル (AU) は,完全な脱毛を引き起こす,最も重度のアルペシア・エリアタ (AA) です.
- テロゲン流出 (TE) としばしば関連しているが,COVID-19は免疫不調,特にインターフェロン-ガンマ (IFN-γ) 媒介の炎症を誘発する可能性がある.
- 慢性的で再発性であるAUは 長期的な管理上の大きな課題を 提示しています
研究 の 目的:
- COVID-19感染後に突然発症し,再発する全身性脱毛症のユニークな症例を紹介する.
- COVID-19後のAUとイディオパシーAUを区別し,その特徴について議論する.
- ウイルスの再発後の長期治療と再発予防戦略の必要性を強調する.
主な方法:
- 脱毛歴のない79歳の女性です
- COVID-19の回復後1ヶ月で突然発症したAUが記録されています.
- コルチコステロイドによる初期治療の詳細,その後の全身療法,および中止後の再発の観察.
主要な成果:
- 患者はCOVID-19の回復から1ヶ月後に突然発症したAUを経験しました.
- 当初の局所および内傷性コルチコステロイド治療は効果的ではなかった.
- 系統療法により10ヶ月間にわたって毛髪が大きく増えたが,治療中止から3ヶ月後に再発した.
結論:
- この症例は,COVID-19以降のAUの急速な発症と再発の経過を独特に示しています.
- この発見は,潜在的に維持療法を含む,長期の管理戦略の必要性を強調しています.
- JAK阻害剤のような免疫調節療法に関するさらなる研究は,ウイルス後のAUの有効な長期的な制御のために必要である.

Autoimmune Disorders
666
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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...

Accessory Structures of the Skin: Hair Growth and Types
1.6K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Asthma: Pathogenesis and Management
573
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.
