まとめ
脊髄刺激または慢性疼痛のための内薬剤ポンプ植入を受けた患者の12. 3%にエオシノフィリア,エオシノフィルの値が上昇した状態が発生しました. この発見は,エオシノフィリアと慢性疼痛の免疫状態の間の潜在的な関連を示唆し,悪影響はありません.
科学分野:
- 神経科学
- 免疫学
- 痛みの管理
背景:
- エオシノフィリアは様々な病気に関連していますが,慢性的な痛みとの関連はよく確立されていません.
- 脊髄刺激 (SCS) と内薬物ポンプ (ITP) を含む神経調節は,高インパクトの慢性疼痛に使用されます.
研究 の 目的:
- 慢性疼痛のためにSCSまたはITPの植入を受けた患者のエオシノフィリアの発生率と臨床的関連性を調査する.
- エオシノフィリアが特定の患者の人口統計,診断,または神経調節後の結果と関連しているかどうかを判断する.
主な方法:
- SCSまたはITPの植入を受けた114人の患者の遡及レビュー (2017~2024年).
- エオシノフィリアは,絶対エオシノフィール数 (AEC) ≥350細胞/μLで定義される.
- エオシノフィリアとエオシノフィリアのない患者の人口統計,臨床,検査データを比較する.
主要な成果:
- 患者の12. 3%がエオシノフィリアを示した (AEC平均は547細胞/μL対138細胞/μL).
- 年齢,性別,インプラントの種類,診断,疼痛改善の有意な違いは観察されなかった.
- エオシノフィルのグループでは頭痛や喘息などの併発症が認められ,短期的な合併症や再手術は認められなかった.
結論:
- エオシノフィリアは,神経調節を受けている慢性疼痛患者において,一般患者よりも多い.
- この文脈でのエオシノフィリアは短期的な不良結果と関連していません.
- 慢性的な痛みを伴う 免疫状態を示唆するかもしれません

Nociception
28.4K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Ligand-gated Ion Channels
11.4K
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

Decreased Body Temperature
1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Blood and Nerve Supply to the Bones
15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Analgesia and Pain Management
3.3K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
