- 薬剤耐性(AMR)は、世界的な健康に対する主要な脅威である。
- 治療成績は、耐性遺伝子のみによって決定されるわけではない。
- 細菌集団内および患者間のばらつきは、AMRに大きく影響する。
研究 の 目的:
- AMRにおける微生物および宿主のばらつきの影響を探る。
- 同じ病原体による感染における異なる臨床転帰を説明する。
- 診断と治療法の改善のための経路を特定する。
主な方法:
- 微生物の細胞間ばらつきに関する既存の証拠のレビュー。
- 感染感受性と治療成功に影響を与える宿主関連因子の分析。
- 微生物および宿主のばらつきの概念の統合。
主要な成果:
- 微生物のばらつき(突然変異、遺伝子発現、パーシスター、バイオフィルム)は、抗菌薬ストレス下での生存を可能にする。
- 宿主のばらつき(遺伝学、免疫、併存疾患、マイクロバイオーム、薬物動態)は、感染リスクと治療効果に影響を与える。
- 微生物と宿主のばらつきの組み合わせは、多様な臨床転帰を説明する。
結論:
- AMRに取り組むためには、微生物と宿主の両方のばらつきを理解することが不可欠である。

Development of Antibiotic Resistance
1.1K
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Dosage Regimen: Individualization
151
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Defense Against Bacterial Pathogens
2.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Antimicrobial Effectiveness
876
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
