まとめ
サルコイドーシス患者の中には,細繊維神経病変による痛みと聴覚障害を経験する人もいます. 定量的な感覚検査と神経繊維密度測定は,この状態が確認され,しばしば自律機能不全が伴う.
科学分野:
- 神経学 神経学とは
- 免疫学 免疫学とは
- 皮膚科 皮膚科について
背景:
- サルコイドーシスは,複数の臓器に影響を与える炎症性疾患です.
- 原因不明の痛みや聴覚不全は,サルコイドーシス患者に報告されています.
- 自律的機能障害は,サルコイドーシスの潜在的な合併症でもある.
研究 の 目的:
- 痛みや自律的機能障害のあるサルコイドーシス患者における小繊維神経症の存在を調査する.
- この集団における小繊維神経症に関連した感覚的欠陥を特徴づける.
主な方法:
- 定量感覚検査 (QST) は,31人のサルコイドーシス患者に実施されました.
- 皮膚内神経繊維密度 (IENFD) は7人の患者の皮膚生検で評価されました.
- QSTは熱感度 (熱と寒さ) を測定した.
主要な成果:
- 31人の患者のうち25人 (80.6%) が,熱感の低下,寒感,またはその両方を示した.
- 皮膚生検を受けた7人の患者全員が,対照群と比較して,IENFDの減少を示した.
- これらの発見は,罹患したサルコイドーシス患者における小繊維神経病変を示しています.
結論:
- 細繊維神経症は,一部のサルコイドーシス患者における痛みと失聴の原因である可能性が高い.
- 自律的関与は,サルコイドーシスにおける小繊維神経症と共存することがあります.
- サルコイドーシスにおける小繊維神経症のメカニズムと管理を調査するために,さらなる研究が必要である.

Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

Disorders of the Nervous Tissue
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Gut-Brain Axis
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
