Emerging infectious diseases
|August 27, 2025
まとめ
ヨーロッパでは,重症なA群の estreptococcus感染が増加しました. コルチコステロイドや 血管圧縮薬のような治療は より悪い結果につながり,公衆衛生の協力の必要性を強調しました.
科学分野:
- 小児科
- 感染症
- 流行病学について
背景:
- 2022年9月以降,ヨーロッパではA群のストリプトコッカス (GAS) 感染症が著しく増加しています.
- 子供の重度のGAS感染は,緊急の臨床治療と流行病学的モニタリングを必要とする.
研究 の 目的:
- 小児の重症なA群の estreptococcus感染の特徴と結果を調査する.
- 子供の重症病と死亡率に関連する危険因子を特定する.
主な方法:
- 2022年9月1日から2024年4月1日まで,フランスの34の病院で402人の小児患者を対象に実施された遡及的および前向きな研究.
- 分析には,臨床表現,治療介入,GAS株の分子分類,患者のアウトカム (後遺症または死亡) が含まれていた.
主要な成果:
- 重度のGAS症例のほとんどは呼吸道感染症 (55%) で,皮膚および軟組織感染症の割合は低い (16%).
- 死亡率は3. 5%でした. ヒドロコルチゾン,コルチコステロイド,および血管圧縮剤の治療は,重大な後遺症または死亡と有意に関連していました.
- Emm1 (73. 0%) と emm12 (10. 8%) が優勢で,M1UKクローンは emm1株の50%を占めていた.
結論:
- 重度の小児GAS感染は主に呼吸器系症状を伴うものであり,有害な結果のリスクが大きい.
- コルチコステロイドや血管圧縮薬を含む特定の治療法は,予後が悪いため,臨床管理において慎重に検討する必要がありました.
- 臨床医,研究者,公衆衛生当局の協力が強化されれば,ガスの子どもたちの健康への影響を効果的に軽減できるでしょう.

Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections II: Preventive Measures
2.8K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
