Background:: Human papillomavirus (HPV) infection is a necessary cause for cervical cancer, but the majority of genital HPV infections clear spontaneously. Human leukocyte antigen (HLA) polymorphism influences immune response and genetic susceptibility, and its association with cervical cancer was extensively investigated, but few reports focused on HPV infection.
Methods:: We performed molecular typing of , , and genes as well as of HPV in 1226 women enrolled in the Ludwig-McGill cohort study and investigated the influence on cumulative HPV positivity. HPV types were grouped according to Alphapapillomavirus subgenera that exhibit similar tissue tropism and biological behavior concerning cancer risk. The associations between HLA polymorphisms and HPV infections were estimated using unconditional logistic regression analysis adjusted for age and race.
Results:: *08 and *15:01 were negatively associated with HPV positivity, and similar effects were observed for HPV Subgenus 2 only, which includes HPV16. 08:07 was associated with overall HPV infection and Subgenus 2 positivity. The haplotypes *08-*03:01-*02:01 and *08:07-*04:02 were negatively and positively associated with cumulative HPV positivity, respectively.
Conclusions:: Our data suggest that HLA class I and II polymorphism can influence HPV natural infection.

Objective: Referring all women who tested positive for human papillomavirus (HPV) 16/18 to colposcopy may lead to potential over-referral issues. Triage tests based on cytology results face challenges in achieving accurate diagnoses. Our study aims to assess the clinical effectiveness of PAX1/JAM3 methylation (CISCER) test as a triage method for HPV 16/18-positive women.

Background: Mixed adenoneuroendocrine carcinoma (MANEC) of the cervix is a rare malignant tumor with high malignancy and poor prognosis, of which large-cell neuroendocrine carcinoma and HPV-independent adenocarcinoma are particularly rare, which have been reported limitedly in the literature. Here, we present 2 cases of MANEC of the cervix and discuss important considerations for diagnosing cervical poorly differentiated carcinoma.
Case Presentation: we reported two cases of mixed large cell neuroendocrine carcinoma and adenocarcinoma of the cervix, one HPV-independent and one HPV-associated, both with vaginal bleeding.

The safety and efficacy of vaccination is a subject contentious in the public mind. Despite overwhelming evidence of their benefits to public health, COVID-19 and human papilloma virus (HPV) vaccines have been the focus of intense concerns. While the original phase III trials and post-market phase IV studies have continued to show their benefits and positive safety profile, some authors have attempted to reassess the original trial data, purporting to showing hidden harms for both COVID-19 and HPV vaccines.
