概括
对细胞巨乳病毒 (CMV) 结肠炎的非侵入性血清和便测试显示出低灵敏度,这意味着它们不能取代结肠镜检查. 然而,当结肠镜检查不可能时,积极的结果是可靠的诊断结果.
科学领域:
- 胃肠病学 胃肠病学
- 传染性疾病 传染性疾病
- 诊断医学 诊断医学 诊断医学
背景情况:
- 细胞巨乳病毒 (CMV) 结肠炎的诊断传统上依赖于侵入性结肠镜检查和活检.
- 非侵入性血清和便测试越来越多地被探索用于诊断CMV胆大肠炎,特别是在高风险患者中.
研究的目的:
- 为了评估非侵入性血清和便测试的诊断准确性,以检测CMV大肠炎.
- 为了比较血清CMV聚合酶链反应 (PCR),血清CMV抗原 (Ag) 和便CMVPCR与黄金标准诊断方法的性能.
主要方法:
- 在MEDLINE和Embase上进行了系统的文献搜索,直到2023年10月1日.
- 包括的研究评估了血清CMV PCR,血清CMV Ag和便CMV PCR,以组织组织病理学或PCR作为参考标准.
- 使用随机效应模型的元分析被用于计算聚合诊断性能.
主要成果:
- 包括30项研究:23项用于血清CMV PCR,9项用于血清CMV Ag,7项用于便CMV PCR.
- 聚合灵敏度为62% (血清CMV PCR),38% (血清CMV Ag) 和53% (便CMV PCR) 的情况.
- 聚合的特异性很高:90% (血清CMV PCR),94% (血清CMV Ag) 和91% (便CMV PCR).
结论:
- 血清和便测试对诊断CMV胆固醇炎的敏感性较低,不能取代结肠镜检查.
- 当结肠镜检查不可行时,这些非侵入性测试是有价值的,正确的结果具有高度的特异性.
- 建议在血清和/或便中进行CMV PCR测试,而不是CMV Ag测试,因为它们的性能更好.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
48
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
