概括

在Clostridioides difficile感染 (CDI) 治疗期间或之后同时服用的抗生素显著增加了CDI复发的风险. 谨慎的抗菌药物管理对于预防进一步的CDI发作和有效管理感染至关重要.

科学领域:

传染性疾病传染性疾病
微生物学微生物学
药理学药理学是指药理学的学科.

背景情况:

困难菌感染 (CDI) 是一个重要的医疗相关感染.
抗生素使用是发展CDI的主要危险因素.
患有CDI的患者通常需要同时治疗其他疾病的抗生素治疗.

研究的目的:

评估同时使用抗生素对CDI复发 (rCDI) 的影响.
评估在CDI治疗期间或之后接受抗生素的患者的rCDI率.

主要方法:

住院CDI病例的回顾性审查.
患者根据同时使用抗生素的情况分类:noABx,ABxDURING,ABxAFTER,ABxDuringAfter.
主要结局:CDI在14-90天内复发;次要结局包括重症监护室停留,切除术和再入院.

主要成果:

在457名CDI患者中,有64.1%同时接受抗生素治疗.
复发率为4.3% (noABx),6.1% (ABxDURING),13.8% (ABxAFTER) 和19.1% (ABxDuringAfter). 复发率为4.3% (noABx),6.1% (ABxDURING),13.8% (ABxAFTER) 和19.1% (ABxDuringAfter). 复发率为4.3% (noABx),6.1% (ABxDURING),13.8% (ABxAFTER) 和19.1% (ABxDuringAfter). 复发率为4.3% (noABx),6.1% (ABxDURING),13.8% (ABxAFTER) 和19.1% (ABxDuringAfter). 复发率为4.3% (noABx),6.1% (ABxDURINGAfter). 复发率为4.1% (noABx),6.1% (ABxDURINGAfter) 和7.
在CDI治疗期间和之后 (ABxDuringAfter) 同时使用抗生素显著增加了rCDI风险 (OR 5.67).

结论:

在CDI治疗期间或治疗后不久使用非CDI抗生素的大量使用与复发率的增加有关.
同时服用抗微生物药物会破坏肠道微生物群的恢复,加剧失生症并增加rCDI.
抗菌药物管理对于管理CDI和预防复发至关重要.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Combined Effects of Drugs: Synergism

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Antimicrobial Effectiveness

Antimicrobial Effectiveness

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...

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
