[Detection of neutralizing antibodies and DNA of human papillomavirus 16, 18 in women aged 18-45 years in Funing, Jiangsu province].

Objective: To understand the distributions of DNA and neutralizing antibodies of human papillomavirus (HPV)16, 18 in 18-45 year-old women.
Methods: Totally, 1494 women were enrolled through multistage random sampling in Funing, Jiangsu province. Cervical exfoliated cells were collected from them for HPV DNA testing, and serum samples were taken from them for the detection of HPV16, 18 neutralizing antibodies by using pseudovirion-based neutralization assay(PBNA).
Results: Among the 1494 women, 28(1.9%) and 188(12.6%) were positive for DNA and neutralizing antibody of HPV16 respectively, and 15(1.0%) and 60(4.0%) were positive for DNA and neutralizing antibody of HPV18, respectively. There were no significant differences in the detection rates of DNA and neutralizing antibody of HPV16, 18 among different age groups. About 16.7% of the women were infected with HPV16, 18, or both.
Conclusion: In Funing county of Jiangsu province, most women aged 18-45 years has no immunity to HPV16 and 18, indicating that they are appropriate targets for HPV 16/18 vaccination.
