Human Papillomavirus Prevalence and Genotype Distribution Among Women With Cervical Cytological Abnormalities in Urumqi, Xinjiang, China
ABSTRACTObjectiveTo investigate the genotype distribution and viral loads of human papillomavirus (HPV) among women with cervical cytological abnormalities in Urumqi, Xinjiang, China.MethodsThe HPV genotyping and viral loads were detected in 9351 patients who underwent the ThinPrep cytology test (TCT) using quantitative real‐time polymerase chain reaction.ResultThe overall HPV infection rate was 21.63%, with a predominance of single and high‐risk HPV (hrHPV) infection. The ethnic stratification showed that the infection rates were 17.01% (265/1558) in Uyghur, 21.76% (84/386) in Kazakh, 22.20% (103/464) in Hui, and 22.79% (1490/6539) in Han. The major hrHPV genotype was HPV53 in Kazakh and HPV16 in Uyghur, Han, and Hui ethnic groups. The age‐stratified data suggested that the highest HPV infection rate in Han, Hui, and Kazakh women was among 25–34 year‐olds, but in the 35–44 year‐old group for Uyghur. The infection rates of HPV16 in cervicitis, ASCUS, LSIL, and HSIL groups were significantly different among the five ethnic groups; the viral load of HPV16 showed a positive correlation with the severity of cervical lesions.ConclusionVariations exist in HPV infection and age distribution among different ethnic groups in Xinjiang, while the HPV16 viral load can guide risk stratification of cervical lesion progression.
