まとめ
多くの片頭痛患者は,抗カルシトニン遺伝子関連ペプチド (CGRP) 療法から恩恵を受けますが,3ヶ月後に反応する人もいます. これらの遅いおよび超遅い応答者に対して,マイグレーンの有意な緩和を達成するために,最大12ヶ月の治療期間が必要である.
科学分野:
- 神経学
- 薬理学について
- 臨床医学
背景:
- 片頭痛は 世界的に顕著な神経疾患です
- 既存の予防的な治療は 効能と耐容性が限られていることが多い.
- カルシトニン遺伝子関連ペプチド (CGRP) を標的にするモノクローナル抗体は,新しい治療法を提供する.
研究 の 目的:
- 偏頭痛患者の抗CGRP治療に対する遅いおよび超遅い反応の発生をレビューする.
- 遅れた治療反応の潜在的メカニズムと臨床的意義を探求する.
- 標準の3ヶ月以上の治療期間が必要かどうかを評価する.
主な方法:
- 関連する文献の記述的レビューが行われました.
- PubMed,Web of Science,Google Scholarで広範な文献検索が行われました.
- 2025年7月まで発表された研究は,現実世界のデータに焦点を当てて含まれています.
主要な成果:
- 実際の世界での研究では,CGRP治療に初期に反応しなかった患者のかなりの割合が,後に臨床的利益を得ていることが示されています.
- 約3分の1の非応答者は6ヶ月で改善した ("遅い応答者"),さらに12ヶ月で改善した ("超遅い応答者").
- 抗CGRP相互作用を含む中央無敏感化メカニズムは,これらの遅延反応の基礎であると仮定されています.
結論:
- 大多数の片頭痛患者は,抗CGRP療法に対する遅延または超遅延の反応を経験します.
- 治療期間を3ヶ月以上延長して,遅れた効果を捉える必要があります.
- 遅い反応のメカニズムのさらなる研究は,片頭痛管理戦略を最適化するために正当化されています.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
259
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
400
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Myasthenia Gravis: Overview and Treatment
1.9K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Indirect-Acting Cholinergic Agonists: Pharmacological Actions
828
Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
321
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Parkinson's Disease: Treatment
377
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...
