口腔eb病毒(EBV)感染与毛状白斑和可能的其他口腔疾病有关。许多口腔EBV感染的研究使用手术标本。本研究测试了一种非侵入性刷活检技术作为外科活检的替代方法来研究口腔EBV感染和疾病。从研究对象处获得配对的、同一部位的舌上皮样本,首先通过刷毛,然后通过手术活检。固定刷细胞和手术标本,准备进行组织学切片和/或处理进行核酸提取。通过常规组织学染色和EBV免疫组织化学或原位杂交,刷细胞颗粒切片证实与手术标本组织切片相当,可用于毛状白斑诊断。EBV序列扩增表明,刷状细胞在敏感性(90% vs. 73%)和阴性预测值(93% vs. 82%)方面都优于手术标本。这种非侵入性的刷活检技术将有助于对口腔EBV感染及其发病机制进行更大规模的前瞻性研究。
Oral Epstein–Barr virus (EBV) infection is associated with hairy leukoplakia and possibly other oral diseases. Many studies of oral EBV infection utilize surgical specimens. This study tested a non-invasive brush biopsy technique as an alternative to surgical biopsy to study oral EBV infection and disease. Paired, same-site, samples of tongue epithelium were obtained from research subjects, first by brush and then by surgical biopsy. Brush cells and surgical specimens were fixed and prepared for histologic sectioning and/or processed for nucleic acid extraction. Brush cell pellet sections proved equivalent to surgical specimen tissue sections for hairy leukoplakia diagnosis by routine histologic staining and EBV immunohistochemistry or in situ hybridization. Amplification of EBV sequences demonstrated superiority of the brush cells over surgical specimens for both sensitivity (90% vs. 73%) and negative predictive value (93% vs. 82%). This non-invasive brush biopsy technique should facilitate larger, prospective studies of oral EBV infection and pathogenesis.
