まとめ
抗リカバリー抗体関連自己免疫性脳炎(AE)はまれですが治療可能です。免疫療法と抗てんかん薬による早期診断と管理により、てんかんと認知機能障害のある患者の転帰が改善します。
科学分野:
- 神経学; 免疫学; 腫瘍学
背景:
- 自己免疫性脳炎(AE)は、てんかんと神経精神症状を引き起こす自己免疫疾患を包含します。 リカバリー抗体は、通常、腫瘍随伴性網膜症に関連していますが、神経学的および精神医学的状態との関連はまれです。 抗リカバリー抗体関連辺縁系AEの症例はほとんど報告されていません。
研究 の 目的:
- 成人における抗リカバリー抗体陽性辺縁系AEの症例を報告すること。 脳脊髄液(CSF)における抗リカバリー抗体検査の診断的価値を例示すること。 このまれな病状の管理と2年間の予後についての洞察を提供すること。
主な方法:
- 側頭葉てんかん、不眠症、認知機能障害を呈した33歳女性の症例。 診断ワークアップには、EEG、MRI、および血液およびCSF中の抗リカバリー抗体の検査が含まれました。 治療には、静脈内メチルプレドニゾロン、静脈内免疫グロブリン(IVIG)、および抗てんかん薬(レベチラセタム、ラモトリギン)が含まれました。
主要な成果:
- 患者は、血液および脳脊髄液中の抗リカバリー抗体が陽性である確定的な辺縁系AEと診断されました。 脳MRIでは、両側海馬および視床の病変が明らかになりました。 2年間の追跡調査の後、患者は臨床的および放射線学的改善を示し、抗体陽性は持続しましたが減少しました。
結論:
- CSF中の抗リカバリー抗体の検査は、AEのまれな症例の診断に価値があります。 抗リカバリー抗体関連AEは、成人の亜急性脳症およびてんかんの治療可能な原因です。 免疫療法と抗てんかん薬を組み合わせた迅速な管理は、長期的な後遺症を軽減するために重要です。

Autoimmune Disorders
1.8K
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.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Actions
2.9K
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.

Waterproofing and Anti-Bacterial Admixtures in Concrete
244
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.

Antibody Structure and Classes
9.3K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

Radical Anti-Markovnikov Addition to Alkenes: Mechanism
4.8K
The reaction of hydrogen bromide with alkenes in the presence of hydroperoxides or peroxides proceeds via anti-Markovnikov addition. The radical chain reaction comprises initiation, propagation, and termination steps.
The mechanism starts with chain initiation, which involves two steps. In the first chain initiation step, a weak peroxide bond is homolytically cleaved upon mild heating to form two alkoxy radicals. In the second initiation step, a hydrogen atom is abstracted by the alkoxy...
