概括

以探针为基础的共聚焦激光内显微镜 (pCLE) 进行的光学活检有助于诊断轻微的肺气膜蛋白质症 (PAP). 轻度PAP病变的PCLE图像与严重病例相似,表明可比的膜巨细胞功能障碍.

科学领域:

肺部病理学肺部病理学
医疗成像医学成像
病理学病理学病理学

背景情况:

轻微的肺膜蛋白质症 (PAP) 诊断是具有挑战性的,因为斑点性病变和有限的活检样本.
轻度和严重的PAP之间的病理差异需要进一步阐明.
胸部CT使用量的增加揭示了更多轻度,无症状的PAP病例.

研究的目的:

为了澄清轻度PAP的病理发现.
评估光学活检的诊断效用,使用基于探针的共聚焦激光内分显微镜 (pCLE).

主要方法:

用pCLE进行支气管镜光学活检和组织活检,对5名PAP患者 (3名轻度,2名重度) 进行.
在pCLE图像中比较了轻度和严重的PAP,整合了临床,病理和CT数据.

主要成果:

在PAP中,pCLE揭示了巨细胞,无形物质和薄膜壁.
在轻度PAP中受影响的病变显示了与严重PAP相似的PCLE图像.
轻度PAP病例显示自发改善或稳定;所有患者都有抗GM-CSF抗体.

结论:

pCLE光学活检为轻度PAP提供了特定的诊断结果.
在轻度和严重的PAP中,类似的PCLE发现表明了可比的膜巨细胞功能障碍水平.

Immunofluorescence Microscopy

Immunofluorescence Microscopy

A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.
