Brief Summary:
Since other genital infections enhance HIV susceptibility by inducing inflammation, the investigators study the relationship between the vaginal microbiota composition and the persistence infection and clearance of HPV infection.
Detailed Description:
Persistent infection with oncogenic Human Papillomavirus (HPV) is necessary but not sufficient for the development of cervical cancer. Additional factors correlated with HPV persistence include immunodeficiency caused by HIV, smoking, use of oral contraceptives and, more recently reported, vaginal dysbiosis. In a state of dysbiosis, there is a marked reduction of Lactobacillus and a high diversity of bacteria, with increased abundance of anaerobic bacterial species. High-risk HPV cervical infections are common in young, sexually active women. Most of these infections are transient and do not cause clinical symptoms. After 12-30 months of HPV infection, 70-90% of patients can be cleared naturally, but there are still a small number of patients with high-risk HPV infection can not be eliminated by itself and continue to infect, and can develop into cervical intraepithelial neoplasia, eventually progressing to invasive cervical cancer. Persistent infection of high-risk HPV is a necessary condition for the occurrence of cervical cancer and precancerous lesions. Early blocking of persistent infection of high-risk HPV and timely treatment of cervical precancerous lesions are of great significance in preventing the occurrence of cervical cancer. This project intends to study the relationship between vaginal microbial composition and persistent HPV infection, and determine the related strains and their molecular mechanisms, so as to provide new ideas and basis for its treatment.
