靶向 PCR 与急性眼内炎 (Targeted PCR)
2016年7月29日 更新者：University Hospital, Grenoble
通过实时 PCR 快速分子细菌鉴定在术后急性眼内炎管理中的贡献
眼内炎是一种严重的外源性（手术后、创伤后）或内源性（转移性）眼部感染。 这是诊断和治疗的紧急情况。
每个患有眼内炎的患者都必须立即进行眼部取样、眼内注射抗生素和全身抗生素覆盖。
病原学治疗将根据感染因子进行调整。
研究概览
详细说明
这项前瞻性多中心试验的主要目标是提高眼内炎病例中传染性病原体鉴定的灵敏度和速度，特别是在真实眼部样本的帮助下从眼部样本中鉴定毒性物种（如金黄色葡萄球菌、肺炎链球菌......）时间聚合酶链反应。
这将有助于眼科医生根据细菌的种类更有效率。
数据还将能够比较本研究中使用的两种 PCR 技术。 前瞻性研究的次要目标是通过抗菌谱和耐药基因研究来表征急性眼内炎期间发现的细菌种类的耐药性，以便能够将体外耐药性与体内治疗反应相关联，并获得宝贵的流行病学数据，以适应预防性抗生素。
