まとめ
メポリズマブは,慢性鼻炎 (CRS) 患者におけるエオシノフィルとCTスキャンスコアを効果的に低下させた. 症状の改善は様々で,CRSのフェノタイプに対するパーソナライズされた治療アプローチを示唆しています.
科学分野:
- 免疫学 免疫学とは
- 耳鼻喉科 (Otorhinolaryngology) は,耳鼻喉科 (Otorhinolaryngology) を専門とする医療機関である.
- 薬理学 薬理学とは
背景:
- メポリズマブは,IL-5を阻害することによって,エオシノフィルの2型炎症を標的とする.
- メポリズマブに対する限られた実世界のデータは,初次拡散CRSおよび鼻ポリープのないCRS (CRSsNP) で存在します.
- 本研究では,鼻のポリップの状態に関係なく,現実世界の拡散CRS患者におけるメポリズマブの有効性を評価しています.
研究 の 目的:
- メポリズマブの実用的な有効性を評価するために,一次分散型CRS.
- 異なるCRS現象型 (CRSwNP vs. CRSsNP) に関するアウトカムを分析する.
- 前回の内視鼻腔外科手術 (ESS) がメポリズマブ治療の結果に与える影響を評価する.
主な方法:
- メポリズマブを6ヶ月以上治療した277人の成人患者における原発的拡散性CRSの遡及的分析.
- 測定されたアウトカムには,血清エオシノフィルの数,Lund-Mackay CTスコア,Lund-Kennedy内視スコア,SNOT-22症状スコアが含まれていました.
- CRSのフェノタイプとESSの過去の経歴に基づいてサブグループ分析を実施し,生物学的スイッチングと中止を記録しました.
主要な成果:
- メポリズマブは,すべてのサブグループで血清エオシノフィルとLund-Mackay CTスコアを著しく低下させた (p<0.001).
- SNOT-22と内視スコアの改善は,控えめで不一致でした.
- CRSwNP患者は,治療中にESSの可能性が高いことを示したが,治療後の最初のESSまでの時間は,CRSsNPと比較して長かった.
結論:
- メポリズマブは,フェノタイプまたは以前の手術に関係なく,初次拡散CRSにおけるエオシノフィリアと放射線学的疾患を効果的に軽減しました.
- 変数的な症状改善は,IL-5阻害に対する患者の反応の異質性を強調しています.
- 発見は,エンドタイプ主導の生物学的治療法を支持し,選択されたCRSsNP患者に潜在的に利益をもたらします.

Drugs Used in Upper Respiratory Disorders: Overview
725
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
2.0K
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Epistaxis
626
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
