ABSTRACT
BACKGROUND:
It is important to assess the relationship between specific HPV genotype or multiple infection and cervical cytology. The protection provided by the HPV vaccine is type-specific, and the epidemiology feature of coinfections needs to be investigated. The aim is to provide baseline information for developing HPV vaccination and management of HPV-positive populations in the region.METHODS:
A total of 3649 HPV-positive women were collected from 25,572 women who underwent 15 HR-HPV genotypes and ThinPrep cytologic test (TCT) results. Logistic regression was used to determine the correlation between the risk of cytology abnormalities and specific HPV infection. We calculated odds ratios (ORs) to assess coinfection patterns for the common two-type HPV infections. chi-squared test was used to estimate the relationship between single or multiple HPV (divided into species groups) infection and cytology results.RESULTS:
The results showed there was a positive correlation between HPV16 (OR = 4.742; 95% CI 3.063-7.342) and HPV33 (OR = 4.361; 95% CI 2.307-8.243) infection and HSIL positive. There was a positive correlation between HPV66 (OR = 2.445; 95% CI 1.579-3.787), HPV51 (OR = 1.651; 95% CI 1.086-2.510) and HPV58(OR = 1.661; 95% CI 1.166-2.366) infection and LSIL. Multiple HPV infections with α9 species (OR = 1.995; 95% CI 1.101-3.616) were associated with a higher risk of high-grade intraepithelial lesions (HSIL) compared with single HPV infection. There were positive correlations between HPV66 and HPV56 (α6) (OR = 3.321; 95% CI 2.329-4.735) and HPV39 and HPV68 (α7). (OR = 1.677; 95% CI 1.127-2.495). There were negative correlations between HPV52, 58, 16 and the other HPV gene subtypes.CONCLUSION:
HPV33 may be equally managed with HPV16. The management of multiple infections with α9 may be strengthened. The 9-valent vaccine may provide better protection for the population in Chongqing currently. The development of future vaccines against HPV51 and HPV66 may be considered in this region.Palabras clave
