The actual prevalence of cancer-related human papillomavirus (HPV) genotypes in cervical acetowhite lesions has not been established. In this work, the presence of oncogenic types of HPV in cervical acetowhite tissue was evaluated by molecular means. The presence of HPV DNA was determined in a group of women with and without cervical acetowhite lesions by a polymerase chain reaction (PCR) using the MY09/MY11 primers. The presence of 13 oncogenic HPV types was evaluated using the Hybrid Capture II test, and the prevalence of HPV type 16 (HPV16) was studied using an HPV16-specific PCR. HPV DNA was detected in 85.9% patients with acetowhite lesions; oncogenic HPV types were found in 83.7% of them; HPV16 was identified in 51.1% of the cases. HPV DNA was detected in 87.3% of the patients without acetowhite changes. Interestingly only 16.8% were infected by oncogenic genotypes and 2.5% were positive for the presence of HPV16. In conclusion, subclinical infection by oncogenic HPV genotypes is associated with the presence of acetowhite cervical tissue (p < 0.0005). Therefore, women showing acetowhite lesions might be at risk of developing cervical cancer.
宫颈癌醋酸白病变中与癌症相关的人乳头瘤病毒(HPV)基因型的实际流行情况尚未明确。在本研究中,采用分子手段评估了宫颈癌醋酸白组织中致癌型HPV的存在情况。通过使用MY09/MY11引物的聚合酶链反应(PCR),对一组有或无宫颈癌醋酸白病变的女性进行HPV DNA检测。使用杂交捕获II试验评估13种致癌HPV类型的存在情况,并使用HPV16特异性PCR研究HPV16型的流行情况。在85.9%的醋酸白病变患者中检测到HPV DNA;其中83.7%发现有致癌HPV类型;51.1%的病例中鉴定出HPV16。在无醋酸白变化的患者中,87.3%检测到HPV DNA。有趣的是,只有16.8%的患者感染致癌基因型,2.5%的患者HPV16呈阳性。总之,致癌HPV基因型的亚临床感染与宫颈醋酸白组织的存在相关(p < 0.0005)。因此,出现醋酸白病变的女性可能有患宫颈癌的风险。
