まとめ
AQP4-IgG陽性視神経脊髄炎スペクトラム障害(AQP4-IgG+ NMOSD)の患者において、リツキシマブ治療中の感染症は懸念事項である。60歳以上および免疫グロブリンレベルの低下は感染症リスクを予測し、個別化された治療戦略に役立つ。
科学分野:
- 神経学; 免疫学; 薬理学
背景:
- リツキシマブは、アクアポリン4-IgG陽性視神経脊髄炎スペクトラム障害(AQP4-IgG+ NMOSD)の一般的な長期治療法です。
- 感染症は、AQP4-IgG+ NMOSDに対してリツキシマブ療法を受けている患者にとって重大なリスクとなります。
研究 の 目的:
- AQP4-IgG+ NMOSDにおけるリツキシマブとアザチオプリン治療間の感染症発生率と重症度の比較。
- AQP4-IgG+ NMOSD患者におけるリツキシマブ治療中の感染症のリスク因子の特定。
主な方法:
- ドイツ(NEMOS研究グループ)におけるAQP4-IgG+ NMOSD患者の後ろ向き多施設共同コホート研究。
- 人口統計学的および臨床的データ、ならびに実験室マーカー(リンパ球、B細胞、IgG、IgM、IgA)および感染イベントの分析。
- リツキシマブとアザチオプリン治療群間の感染率およびリスク因子の比較。
主要な成果:
- リツキシマブ治療群では170例中92例、アザチオプリン治療群では33例中12例で感染症が発生し、種類とリスクは同等でした(HR=1.24)。
- リツキシマブ治療を受けた60歳以上の患者は、感染症リスクが高かった(HR=1.62)。
- 低ガンマグロブリン血症(低IgGまたは低IgM)およびリンパ球減少症は、リツキシマブ治療中の感染症および入院を予測しました。
結論:
- 60歳以上および低い免疫グロブリン血清レベル(IgG、IgM、IgA)は、リツキシマブ治療を受けているAQP4-IgG+ NMOSD患者における感染症リスクの予測因子です。
- これらの要因は、感染症リスクを軽減するために、AQP4-IgG+ NMOSD患者のリツキシマブ治療決定を個別化するのに役立ちます。

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Serum Studies: Renal Function Tests
441
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Transcytosis of IgG
4.1K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
