Human papillomavirus (HPV) infections are a significant public health concern as they cause various cancers, including those of the cervix, vulva, vagina, anus, penis, and oropharynx, in both women and men.

Individuals with immune-mediated inflammatory diseases, particularly systemic lupus erythematosus, have an increased risk of developing persistent HPV infection and subsequent precancerous lesions due to their immunosuppression.

Vaccination and screening for precancerous lesions are 2 central management strategies that must be implemented in patients with immune-mediated inflammatory diseases. Although HPV vaccination has been proven to be safe and effective in these patients, coverage remains low and should be encouraged. Screening for cervical cancer should be more widely implemented in this population, as recommended in guidelines for other immunosuppressed patients.

Catch-up vaccination, vaginal self-sampling screening for HPV detection, and therapeutic vaccination are new options that should be considered.

The relationship of PAX1/JAM3 methylation as well as HPV viral load (VL) with cervical lesions has been reported, but their role in persistent HPV infection without cervical high-grade lesions has not been fully elucidated. A total of 231 females diagnosed with persistent HPV infection and pathologically confirmed absence of high-grade cervical lesions were selected from the Colposcopy Outpatient Clinic of Peking University People's Hospital, from March 2023 to December 2023. They were categorized into two groups based on the duration of HPV infection: the HPV persistent less than 3 years group and the more than 3 years group. PAX1/JAM3 methylation and HPV VL were determined by real-time PCR and BioPerfectus Multiplex Real-Time (BMRT)-HPV reports type-specific VL/10,000 cells, respectively. The average age of individuals with HPV infection lasting more than 3 years was higher compared to those with less than 3 years (48.9 vs. 45.1 years), with a statistically significant difference. Among the participants, 81.8% (189/231) had no previous screening. The methylation levels of JAM3 and PAX1 were significantly higher in individuals with HPV infection persisting for more than 3 years compared to those with less than 3 years, with a statistically significant difference (p < 0.05). There was a significant correlation between PAX1 and JAM3 methylation (p < 0.001), which could be used as cumulative evidence of HPV infection duration before the occurrence of precancerous lesions. The incidence of vaginal intraepithelial lesions was higher in individuals with HPV infection persisting for more than 3 years compared to those with less than 3 years, and HPV VL can be used as an indicative biomarker for concurrent cervical-vaginal lesions, especially for HPV other than 16/18 genotypes.

Human papillomavirus is a predominant sexually transmitted viral pathogen. Our objective was to analyze the relative distribution of genotypes over time and to determine the genotypes associated with adverse clinical lesions. The study was based on data from adult women with cytological abnormalities from whom histological samples were obtained from 2005 to 2021. HPV genotyping was performed using PCR and INNO-LiPA assay (Fujirebio). Among the 1,017 HPV-positive biopsies, 732 (72%) were infected with a single HPV genotype and 285 (28%) were infected with several HPV genotypes. Most of the infections involved the high-risk genotypes 16, 31, and 52. Throughout the study period, HPV 16 was the most encountered genotype (541, 53.2%), while HPV 18 was rather under-represented (46, 4.5%), especially in invasive cervical carcinoma. HVP52 (165, 16.2%) was detected mainly from 2008 to 2014, and its distribution reached 19.7% in 2011. Such epidemiological data underlines the possibility of an emergence of a high-risk genotype. The most detected low-risk HPV in combination with high-risk HPV was HPV 54 in 6.5% of samples. Monoinfection by HPV 16 led statistically more often to severe lesions than multi-infection involving HPV 16 (p < 0.001), while for HPV 52, 31 or 33, multi-infections were significantly associated with severe lesions (p < 0.001 for each of these three genotypes). HPV 16 was involved in 55.2% of high-grade lesions and in situ carcinoma and 76.3% of invasive carcinomas. In severe lesions, HPV 16 participation was predominant, whereas diverse genotypes were seen in low-grade lesions. Importantly, we observed that high-risk genotypes, for example HPV 52, can emerge for a few years then decrease even without vaccine pressure.

Human papillomavirus (HPV) infection is the primary cause of cervical cancer and its precursor lesions. The overall prevalence of HPV genotypes in Changzhou has previously been reported. However, the distribution of multiple HPV infections and their roles in cervical injury have less been investigated. We aimed to assess the prevalence of multiple HPV infections among the people in Changzhou. Furthermore, we analyzed whether multiple HPV infections comprising the top five prevalent HPVs were more associated with abnormalities in E6 and E7 (E6/E7) mRNA, liquid-based cytology, and cervical histopathology than a single infection. In the current study, HPV 16, 52, 58, 53, and 81 were the top five prevalent HPV types, both in single and multiple infections. Compared to a single infection, multiple infections containing HPV 16/52/58 were closely linked to positivity for E6/E7 mRNA. In addition to HPV 16, multiple infections containing the remaining top four HPVs conferred a significant advantage on atypical squamous cells of undermined significance or worse in comparison to a single infection. Furthermore, women with multiple infections containing the top five prevalent HPV types were more likely to develop cervical intraepithelial neoplasia grade II or worse than those with a single HPV infection. Our results demonstrate the superiority of multiple HPV infections containing the top five prevalent HPV types in cervical disease progression, which should be closely monitored. These findings are conducive for formulating regional preventive strategies for cervical cancer screening and vaccination in Changzhou.

The precise grading and characterization of cervical intraepithelial neoplasia (CIN) has been the focus of pathologists for a long time. This study aimed to explore known strategies for the grading of CINs.

After routine H&E review, 85 lesions graded CIN 1, 2, or 3 were investigated primarily by HPV RNAscope to detect HR-HPV and LR-HPV, in combination with an HPV-DNA test and P16/Ki67 immunohistochemistry (IHC). Then, the 85 cases were divided into a control group (49 cases) and a test group (36 cases). The former consisted of cases with consistency between morphology, HPV DNA detection and P16/Ki67 IHC. We used them to evaluate HPV RNA distribution patterns in CINs of different grades. The latter were ambiguous cases in which pathologists could not confirm the diagnosis because of inconsistencies between morphology, HPV DNA detection and P16/Ki67 IHC. We reassessed them by comparison to the pattern in the control group.

The expression patterns of HPV mRNA signals were different in different CIN lesions. LSIL/CIN1 lesions were mostly expressed in superficial epithelium with diffuse clustered nuclear or cytoplasmic staining; HSIL/CIN2 were characterised by nuclear/cytoplasmic punctate or diffuse cluster nuclear staining in the mid-surface layer, and scattered nuclear/cytoplasmic punctate staining in basal and parabasal cells; whereas HSIL/CIN3 showed full-thickness nucleus/cytoplasmic scattered staining with a punctate pattern. According to the staining pattern, we corrected the diagnosis of 22 cases (22/36, 61.1%).

Because of its distinct location pattern, HPV RNAscope has obvious advantages over the HPV-DNA test, and combined with P16/Ki67 IHC, it can help pathologists correctly grade CIN. In addition, it can effectively discriminate true CIN from normal or CIN mimic lesions, such as immature squamous metaplasia, atrophy, and inflammatory/reactive changes. Therefore, HPV RNAscope is a valuable auxiliary diagnostic test to avoid the overtreatment and undertreatment of CIN lesions.

The aim of the study was to assess the role of behavioral factors in persistence of human papillomavirus (HPV) genital infection. Out of a cohort of 605 women included in a study of HPV infection prevalence, 142 HPV positive women (aged 18-57) were retested after a 12-month interval. None of the patients underwent surgical treatment during that period. Selected patients were asked for a second smear for cytologic analysis and HPV genotyping. A questionnaire that included information regarding reproductive health, sexual activity and smoking status was filled-in. After 12 months, 46 of 142 (32.39%) women had persistent HPV infection, with genotypes 16 and 18 found in 27 cases. On the other hand, 17 of 142 (11.97%) women had acquired new infections replacing the baseline genotypes. In our study, smoking (OR=2.320, p=0.0330) and sexual behavior (OR=5.333, p=0.0180 for more than three sexual partners; OR=2.427, p=0.0238 for cases where the partner was involved in another sexual relationship) were associated with viral persistence, while long-term contraception did not yield statistically significant results.

Cervical cytology is the best single method for large screening of the population in identifying precancerous lesions of the uterine cervix.

To estimate the frequency of human papillomavirus (HPV) positivity in a group of Albanian women, the prevalence of vaginal coinfections, and the relationship of coinfections with HPV, as well as their role in metaplasia or cervical intraepithelial lesions (CIN).

In this retrospective study, 2075 vaginal smears were examined. The Papanicolaou stain was used for all slides. The New Bethesda System 2001 was used for the interpretations of the smears. Data analysis was completed using the Statistical Package for the Social Sciences version 19.0.

Prevalence of HPV positivity was 43.9% with an average age of 35.48 ± 9.27 years. Candida coinfection resulted in 57.8% of HPV positive women with a significant relationship between them. Gardnerella coinfection resulted in 36 (23%), mixed flora in 34 (8%), and Trichomonas vaginalis in 50% of HPV positive woman. Among the women with positive HPV, 19% had CIN, 8% had metaplasia, and 1% had metaplasia and CIN; 9% of the women with HPV had CIN1 and one of the coinfections.

There is a strong relationship between CIN1 and HPV positivity as well as between CIN1 and coinfections. HPV infection is a major factor contributing to metaplasia, and bacterial coinfections in HPV positive women have a statistically significant impact in the development of metaplasia.

The International Agency for Research on Cancer and the National Cancer Institute have acknowledged human papillomavirus (HPV)-16 as an independent risk factor for oropharyngeal cancer (OPC). HPV-positive oropharyngeal cancer (HPVOPC) is a sexually transmitted entity that is on the rise; within the next 10 years, the annual number of HPV-associated OPC cases is projected to exceed the annual number of cervical cancer cases in the United States. Recognition of HPV status in OPC has broad implications beyond the traditional oncological concerns of timely diagnosis, accurate staging, and appropriate treatment of cancer patients. The National Comprehensive Cancer Network recommends testing the tumor site for HPV-status during OPC management; it is likely this will become a standard component of care for patients with high-probability tumors of the oropharynx. As the practice of HPV testing becomes more common, it behooves providers to be able to adequately address the concerns of patients with HPVOPC. Although there are currently few relevant studies focusing on this population, existing literature on HPV-infected women and patients with cervical cancer strongly supports the concept that patients with HPVOPC need education to optimally address concerns such as self-blame, guilt, intimacy, and interpersonal relationships. When HPV testing is done, it should be accompanied by evidence-driven and patient-centered counseling to best minimize negative psychosocial outcomes and ensure optimum health promotion. Based on the current state of the literature, this article is intended to be a reference for physicians to effectively manage psychosocial outcomes when diagnosing patients with HPV-associated OPC.

The aim of this study was to compare the novel human papillomavirus (HPV) detection method, the HPV 4 Auto-capillary Electrophoresis (ACE) test with the hybrid capture (HC) 2 assay for the detection of high-risk HPVs. In addition, we compared the HPV 4 ACE test with the polymerase chain reaction HPV Typing Set test for the detection of HPV 16 and HPV 18 genotypes. One hundred ninety-nine cervical swab samples obtained from women with previous abnormal Pap smears were subjected to testing with the three HPV tests. The HPV 4 ACE test and the HC 2 assay showed substantial agreement for detection of high-risk HPVs (85.4%, kappa=0.71). The HPV 4 ACE test also showed substantial agreement with the PCR HPV Typing Set test in the detection of HPV 16 and HP V 18 genotypes (89.9%, kappa=0.65). In correlation with cytologic results, the sensitivities and specificities of the HPV 4 ACE test and HC 2 assay were 92.9% vs. 92.9% and 48.1% vs. 50.8%, respectively, when high-grade squamous intraepithelial lesions were regarded as abnormal cytologies. The novel HPV 4 ACE test is a valuable tool for the detection of high-risk HPVs and for genotyping of HPV 16 and HPV 18.
