Background: The human papillomavirus (HPV) Persistence and Progression Cohort is a natural history study of carcinogenic HPV positive women. Here, we present the HPV genotypes found in first ∼500 cases of cervical intraepithelial neoplasia grade 3 (CIN3) or more severe disease (CIN3+) diagnosed at the study baseline.
Methods: Women aged 30 and older were screened for cervical cancer using Pap smears and tested for carcinogenic HPV using Hybrid Capture 2 (HC2; Qiagen). We randomly selected women who tested HPV positive and were diagnosed with CIN3+ (n = 448) or without CIN3+ (
Results: Among HC2-positive women, HPV16 (48.9%), HPV31 (9.2%), and HPV18 (8.5%) were the most common HPV genotypes in CIN3+. There was a decrease at older ages in the fraction of CIN3 (P(trend) = 0.006), adenocarcinoma in situ (AIS) (P(trend) = 0.08), and CIN3/AIS (P(trend) = 0.002) associated with HPV16. Compared to the other carcinogenic HPV genotypes in aggregate, HPV18 was strongly associated with CIN3+ in women with a normal Pap [odds ratio (OR) = 5.7, 95% CI = 1.2-26] but not in women with abnormal Pap (OR = 1.3, 95% CI = 0.74-2.3).
Conclusions: HPV16 is more strongly associated with cervical precancer diagnosed in younger women (vs. older women). HPV18 infections were linked to precancerous lesions that were missed by cytology.
Impact: The progression timeline of HPV16 differs from other carcinogenic HPV genotypes, which may impact the use of HPV16 detection in the management of HPV-positive women.

Upon infection, human papillomavirus (HPV) manipulates host cell gene expression to create an environment that is supportive of a productive and persistent infection. The virus-induced changes to the host cell's transcriptome are thought to contribute to carcinogenesis. Here, we show by RNA-sequencing that oncogenic HPV18 episome replication in primary human foreskin keratinocytes (HFKs) drives host transcriptional changes that are consistent between multiple HFK donors.

This study examined the relationship between the vaginal microbiome, HPV infection, and cervical intraepithelial neoplasia (CIN) in 173 women. Subjects were grouped by HPV status and cervical lesion severity, ranging from HPV-negative to CIN Grade 2 or higher. Using VALENCIA classification, the study identified different community state types (CSTs) of vaginal microbiota, with CST IV subtypes (Staphylococcus dominated) showing high diversity and increased pathogenic bacteria.

SUMMARYHuman papillomaviruses (HPVs) are small DNA viruses that are responsible for significant disease burdens worldwide, including cancers of the cervix, anogenital tract, and oropharynx. HPVs infect stratified epithelia at a variety of body locations and link their productive life cycles to the differentiation of the host cell. These viruses have evolved sophisticated mechanisms to exploit cellular pathways, such as DNA damage repair (DDR), to regulate their life cycles.

Incorporating molecular testing for human papillomavirus (HPV) into the screening of cervical specimens can improve risk stratification and, in turn, patient management. Infection with a high-risk (HR) HPV genotype is associated with greater risk for persistent infection, viral integration, and progression of cervical neoplasia. Current guidelines consider HPV 16 or HPV 18 clinically actionable with referral to colposcopy; however, 12 Other HR HPV genotypes have been associated with cervical cancer risk, suggesting a benefit of extended genotyping.
