概括
在便微生物种移植 (FMT) 后使用抗生素会增加复发性困难 Clostridioides 感染 (CDI) 的风险. 免疫功能低下的状态,先前的抗生素和CDI住院预测FMT后的抗生素使用,需要有针对性的预防策略.
科学领域:
- 微生物学 微生物学
- 胃肠病学 胃肠病学
- 传染性疾病 传染性疾病
背景情况:
- 复发性困难菌感染 (CDI) 源于抗生素诱导的肠道微生物群破坏.
- 便微生物群移植 (FMT) 有效地恢复微生物群以预防CDI,但暴露于抗生素可能会降低其疗效.
- 识别FMT后抗生素使用的风险因素对于管理复发性CDI至关重要.
研究的目的:
- 在患有复发性CDI的患者中,在FMT后与非CDI抗生素治疗相关的风险因素的识别.
主要方法:
- 这是一项前性队列研究,涉及6个美国机构的448名为复发性CDI接受FMT的患者.
- 收集的数据包括患者在FMT给药时和随后的几个月中的病情.
- 统计分析在FMT后2个月内确定了非CDI抗生素使用的风险因素.
主要成果:
- 免疫功能受损状态 (OR,2.2),之前三次以上的非CDI抗生素疗程 (OR,3.1),以及之前的CDI住院治疗 (OR,2.0) 是FMT后非CDI抗生素管理的显著风险因素.
- 尿路感染,呼吸道感染和手术预防是FMT后使用抗生素的最常见原因.
- 这些因素具有统计学意义 (P < .05).
结论:
- 在FMT后暴露于非CDI抗生素显著增加了CDI复发的风险.
- 在FMT后使用抗生素的关键风险因素包括免疫功能受损的状态,多次先前的抗生素疗程和先前的CDI住院治疗.
- 患有这些风险因素的患者可能需要加强或修改预防复发性CDI的策略.

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...

Irritable Bowel Syndrome I: Introduction
211
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Factors Affecting the Risk of Infection
10.7K
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...

What is Monogastric Digestion?
70.3K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Pulmonary Tuberculosis I
214
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
288
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
