. Previous studies reported human papillomaviruses (HPVs) in middle ear tumors, whereas these viruses have been poorly investigated in chronic inflammatory middle ear diseases. We investigated HPVs in non-tumor middle ear diseases, including chronic otitis media (COM). . COM specimens (n = 52), including chronic suppurative otitis media (CSOM) (n =38) and cholesteatoma (COMC) (n = 14), as well as normal middle ear (NME) specimens (n = 56) were analyzed. HPV sequences and DNA loads were analyzed by quantitative-PCR. HPV genotyping was performed by direct sequencing. . HPV DNA was detected in 23% (12/52) of COM and in 30.4% (17/56) of NME ( > 0.05). Specifically, HPV DNA sequences were found in 26.3% (10/38) of CSOM and in 14.3% (2/14) of COMC ( > 0.05). Interestingly, the HPV DNA load was higher in COMC (mean 7.47 copy/cell) than in CSOM (mean 1.02 copy/cell) and NME (mean 1.18 copy/cell) (P = 0.03 and P = 0.017 versus CSOM and NME, respectively). HPV16 and HPV18 were the main genotypes detected in COMC, CSOM and NME. . These data suggest that HPV may infect the middle ear mucosa, whereas HPV-positive COMCs are associated with higher viral DNA loads as compared to NME.
以往研究报道过人乳头瘤病毒(HPV)存在于中耳肿瘤中,而这些病毒在慢性炎症性中耳疾病中的研究较少。我们对包括慢性中耳炎(COM)在内的非肿瘤性中耳疾病中的HPV进行了研究。分析了52例COM标本,包括38例慢性化脓性中耳炎(CSOM)和14例胆脂瘤型中耳炎(COMC),以及56例正常中耳(NME)标本。通过定量PCR分析HPV序列和DNA载量。通过直接测序进行HPV基因分型。在23%(12/52)的COM和30.4%(17/56)的NME中检测到HPV DNA(P>0.05)。具体而言,在26.3%(10/38)的CSOM和14.3%(2/14)的COMC中发现了HPV DNA序列(P>0.05)。有趣的是,COMC中的HPV DNA载量(平均7.47拷贝/细胞)高于CSOM(平均1.02拷贝/细胞)和NME(平均1.18拷贝/细胞)(与CSOM和NME相比,P分别为0.03和0.017)。HPV16和HPV18是在COMC、CSOM和NME中检测到的主要基因型。这些数据表明HPV可能感染中耳黏膜,而与NME相比,HPV阳性的COMC与更高的病毒DNA载量相关。
