概括
序列C反应蛋白 (CRP) 变化适度指导抗生素决策,但在疑似感染中强烈预测死亡率. 将CRP与其他因素结合起来,可以优化患者护理和抗生素管理.
科学领域:
- 临床微生物学 临床微生物学
- 传染性疾病 传染性疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 序列C反应蛋白 (CRP) 测量用于监测感染恢复,但其临床实用性仍有争议.
- 之前的研究建立了可疑血流感染 (BSI) 的CRP百分位基准图.
- 这项研究调查了CRP变化,抗生素处方以及疑似感染患者的治疗结果.
研究的目的:
- 评估连续CRP百分位数变化与抗生素处方模式之间的关联.
- 评估CRP变化与患者结果 (包括死亡率) 之间的关系.
- 了解CRP在感染管理临床决策中的作用.
主要方法:
- 分析了来自英国36,578名患者 (2016-2021) 的51544例疑似感染病例.
- 根据血液培养结果对病例进行分类 (格拉姆阳性,格拉姆阴性,多微生物,污染物,培养阴性).
- 统计建模 (逻辑回归,混合模型) 来评估CRP变化,抗生素处方和死亡率之间的关联.
主要成果:
- 抗生素处方显示从宽谱向窄谱的转变,格兰氏阴性/多微生物感染的缓慢降级.
- CRP百分位数的变化与抗生素调整有轻微的联系;低于最佳的恢复与升级相关,与降低升级的更快的恢复.
- 早期的CRP变化 (1-4天) 强烈预测了5-30天的死亡率,表明了预后价值.
结论:
- CRP监测为抗生素管理提供了洞察力,但与处方决策的联系很小.
- 优化感染管理需要将CRP趋势与全面的临床因素集成在一起.
- 在疑似感染的患者中,CRP变化是有价值的预后指标.

Combined Effects of Drugs: Synergism
4.7K
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.

Urine Studies II: Urine Culture and Sensitivity Test
116
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

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...
