Detecting and genotyping high-risk human papillomavirus among male patients during 2015–2023 in Beijing, China

ABSTRACT Few studies focused on human papillomavirus (HPV) in male patients. This study aimed to explore the detection rate and genotyping of HPV among male patients in Beijing to provide a reference for formulating prevention strategies for HPV infection. The cross-sectional study was conducted in Beijing Chaoyang Hospital from November 2015 to March 2023. It covered male patients from the urology and dermatology departments. Fifteen high-risk HPV genotypes were detected by the multiplex real-time polymerase chain reaction method. The overall detection rate of HPV was 25.19% (1288/5114, 95% confidence interval [CI] 24.00%−26.38%), of which the single infection rate was 16.99% (869/5114, 95% CI 15.97%−18.05%) and the co-infection rate was 8.19% (419/5114, 95% CI 7.46%−8.98%). The detection rate of HPV was 40.77% (521/1278), 35.58% (58/163), 32.69% (101/309), 31.91% (60/188), 12.63% (299/2367), and 32.35% (131/405) among male patients with balanitis, warts, rash, urethritis, prostatitis, and other urinary inflammation, respectively (P < 0.001). The top five HPV genotypes were HPV-52, HPV-58, HPV-16, HPV-51, and HPV-66. After the first positive HPV test, the proportion of male patients who turned negative was 22.47% within 3 months, 26.40% within 3−6 months, 24.72% within 6−12 months, 17.98% within 12−24 months, and 8.43% more than 24 months. The detection rate of HPV was high among male patients from the urology and dermatology departments in Beijing, which should be considered to develop HPV vaccines with better prevention effects.

Logistic regression analysis of mRNA expression changes and prognosis after cervical surgery

Objective: The aim of this study was to investigate the diagnostic value of HPV (human papillomavirus) E6/E7 mRNA combined with thin-layer liquid-based cytology test (TCT) detection in patients with cervical intraepithelial neoplasia (CIN) in the residual and recurrence of lesions after cervical conization. Methods: A total of 154 patients who had undergone cervical conization and were diagnosed with high-grade cervical intraepithelial neoplasia (CIN 1 and CIN 3) by histopathology and had complete follow-up data were enrolled. TCT, HPV-DNA detection, and HPV E6/E7 mRNA detection combined with TCT detection in 12 months can be used to detect abnormal cytology (&amp;gt;atypical squamous epithelium of undetermined significance). Patients with atypical squamous cell of undetermined significance or high-risk HPV-DNA (+) or HPV E6/E7 mRNA combined with TCT (+) underwent colposcopy and cervical biopsy again for pathological diagnosis. Results: There were 9 cases of residual lesions and 22 cases of recurrence. Thirty of the 57 cases with positive HPV-DNA after surgery were still there or came back. Of the 26 cases with positive HPV E6/E7 mRNA combined with TCT, 24 were still there or came back. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy rate of HPV-DNA detection were 96.8%, 78.0%, 52.6%, 99.0%, and 81.8%, respectively; the sensitivity and specificity of HPV E6/E7 mRNA were combined with TCT detection of sex. Conclusion: HPV E6/E7 mRNA combined with TCT detection can be included in follow-up examinations, which can timely and effectively predict the risk of CIN residual or recurrence after cervical conization and reduce excessive examination and treatment.

Prevalence, risk factors and genotype distribution of human papillomavirus infection among women with and without invasive cervical cancer: Findings from a hospital-based study in Bihar, India.

Background Human papillomavirus (HPV) infection is largely responsible for the development of invasive cervical cancer (ICC). Its prevalence, risk factors and genotype distribution among women residing in Bihar (third most populous Indian state) with and without ICC are not well known. Methods In this hospital-based study, we followed up 1439 participants with cytology and HPV report. HPV detection and genotyping were performed using the TaqMan-based real-time PCR method. Clinical and sociodemographic data were collected and analysed using statistical methods. Results The overall prevalence of HPV infection was 37.3% (537/1439) and 11 different types of HPV genotypes were observed. Higher HPV positivity was found in premalignant, intraepithelial and invasive malignant lesions of the cervix; 73.8% (93/126) of atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) and high-grade squamous intraepithelial lesions (HSIL) and 93.4% (114/122) of invasive malignancies were infected with HPV in comparison to only 26.1% (245/938) of negative for intraepithelial lesion or malignancy (NILM) cytology. Moreover, HPV was found in 95.2% (236/248) of histologically confirmed cases of carcinoma cervix. HPV16 and HPV18 infections were reported in 78.2% (194/248) and 8.9% (22/248), respectively. The remaining patients had infection with other high-risk strains/co-infection with multiple strains or were HPV-negative. Various socio-demographic factors including women >50 years of age, >10 years of marriage and high parity were significantly associated with HPV infection. Conclusion Our data suggest that HPV16 infection may be the major cause for ICC among women residing in Bihar. Our findings may serve as a baseline for developing an appropriate screening and vaccination strategy for Bihar.

Factors associated with human papillomavirus persistence after loop electrosurgical excision procedure in patients with cervical squamous intraepithelial lesion.

To seek the high-risk factors of human papillomavirus (HPV) persistence and residual lesion or recurrence after loop electrosurgical excision procedure (LEEP) focus on the predictive value of intraoperative human papilloma virus (IOP-HPV) testing. Intraoperative endocervical sample was obtained with a cytobrush from the remained cervix of 292 patients immediately after LEEP. HPV Genotyping was performed using a polymerase chain reaction technique. All patients followed by HPV genotyping and cytology every 3-6 months. The IOP-HPV testing results and possible risk factors such as age, cytology grade, menopause status, margin involvement, preoperative HPV status, and cervical lesion grade were assessed in predicting persistence of HPV and residual lesion or recurrence after surgery. There were 61 (20.9%) patients presented persistent HPV infection. Multivariate analyses showed that IOP-HPV positive, post-menopause and preoperative HPV multiplex infection was strongly associated with HPV persistence after LEEP, IOP-HPV positive and post-menopause was also associated with residua or recurrent disease after LEEP. IOP-HPV positive, post-menopause, and preoperative HPV multiplex infection are independent predictors of HPV persistence in patients with cervical squamous intraepithelial lesion treated by LEEP. IOP-HPV test is a new approach that may potentially allow for early identification of patients at high risk of HPV persistence and residua or recurrent disease after LEEP, thereby possibly facilitate an attenuated follow-up schedule for negative patients those at low risk of persistent HPV infection.

HPV positivity status in males is related to the acquisition of HPV infection in females in heterosexual couples

PurposeFew studies have focused on the impact of human papillomavirus (HPV) positivity in male partners on female HPV infection and cervical lesions. The purpose of this study was to evaluate the impact of the HPV infection status of husbands on wives’ cervical HPV infection and lesions.MethodsWe surveyed 251 monogamous couples who attended the outpatient department of Fujian Maternity and Child Health Hospital from 2013 to 2021. HPV type analysis was performed on exfoliated cells of the females’ cervix and males’ urethra by the PCR-reverse dot blot method. We analyzed the prevalence and consistency of HPV types in 251 couples. Subsequently, the risk of HPV infection in females with HPV-positive male partners was analyzed. SPSS version 26 (IBM, Chicago, USA) was used for statistical analysis.ResultsIn 251 couples, the most commonly detected high-risk HPV (HR-HPV) genotypes were 52, 51, 16, and 58 for males and 16, 52, 18, and 58 for females. Wives with HPV-positive husbands had higher infection rates for most HR-HPV genotypes. HR-HPV positivity in husbands was a risk factor for the development of cervical lesions in wives (OR = 2.250, P = 0.014). Both single-type (OR = 2.085, P = 0.040) and multiple-type (OR = 2.751, P = 0.036) infection in husbands will contributed to an increased risk of non-HR-HPV infection and cervical lesions in wives.ConclusionHusbands’ HPV positivity increases the burden of non-HR-HPV infection and increases the risk of cervical lesions developing in wives. It is hoped to provide a reference value for cervical cancer prevention in females and HPV vaccination in males.

Detection of Multiple HPV Types in Liquid Biopsies of Cervical Neoplasia.

More than 95% of cervical cancers and their precancerous lesions are caused by human papillomavirus (HPV). Cell-free (cf) HPV DNA detection in blood samples may serve as a monitoring tool for cervical cancer. In our methodological study, an HPV panel for simultaneous detection of 24 types using mass spectrometry-based analysis was developed for liquid biopsy approaches and tested on HPV positive cell lines, plasmid controls, and cervical high-grade squamous intraepithelial lesions (HSIL) in positive smear samples (n = 52). It was validated in cfDNA blood samples (n = 40) of cervical cancer patients. The HPV panel showed proficient results in cell lines and viral plasmids with a limit of detection of 1 IU (international units)/µL for HPV16/18 and 10GE/µL for HPV11/31/33/39/45/51/52/58/59 and a specificity of 100% for the tested HPV types. In cervical smear samples, HPV DNA was detected with a sensitivity of 98.14%. The overall agreement between the new HPV panel and clinical records was 97.2% (κ = 0.84). In cervical cancer cfDNA, 26/40 (65.0%) tested positive for any HPV type, with most infections due to hrHPV (24/26). HPV positive samples were found in all FIGO stages, with the highest positivity ratio in FIGO III and IV. Even the lowest stage, FIGO I, had 12/23 (52.2%) patients with a positive HPV plasma status. This proof-of-concept paper shows that the described assay produces reliable results for detecting HPV types in a multiplex mass spectrometry-based assay in cervical smear and cfDNA with high specificity and sensitivity in both cohorts. The assay shows potential for liquid biopsy-based applications in monitoring cervical cancer progression.

PD-L1 immunohistochemical expression considering HPV status in oropharyngeal squamous cell carcinoma.

This systematic review aims to determine whether the presence of human papillomavirus (HPV) influences the immunohistochemical expression of programmed cell death-1 ligand (PD-L1) in oropharyngeal squamous cell carcinoma (OPSCC). PD-L1 immunohistochemical expression varies in OPSCC, and the presence of HPV is a plausible explanation for this variability. Comprehending these findings is crucial, as high PD-L1 expression in the tumor microenvironment of OPSCC can help identify patient subgroups that could be suitable for immunotherapy. Therefore, a systematic review was conducted following PRISMA guidelines (CRD42023437800). An electronic literature search was performed without time or language restrictions. The search included PubMed/MEDLINE, Embase, Scopus, Web of Science, https://clinictrials.gov, and relevant journals. A meta-analysis was performed using RStudio. Fourteen studies involving 1,629 participants were included. The sample consisted predominantly of males (81.26%) with a mean age of 58.3 years. Concerning clinical and pathological characteristics, the most frequently described anatomical location was the tonsils (68.54%), and most participants were either current or former smokers (78%) and alcohol users (79%). Advanced TNM IV was the most common stage. Regarding histopathological characteristics, HPV 16 was the only type mentioned, and half of the cases were detected through immunohistochemistry. The SP142 clone (35.7%) and the pattern of membrane immunostaining in tumor cells (71%) were the most commonly employed methods. The most prevalent findings were positive expression of PD-L1 (64.28%) and negative HPV status (57.14%). The association between PD-L1 positivity and HPV positivity (78.57%) was confirmed by meta-analysis. The conclusion was that HPV-positive status has an impact on immunohistochemical expression of PD-L1 in OPSCC.

Significance of negative cervical cytology and positive HPV in the diagnosis of cervical lesions by colposcopy.

The aim of this study was to investigate the significance of colposcopy in diagnosing cervical lesions when negative cervical cytology is combined with positive human papillomavirus (HPV). Overall, 370 patients with cervical epithelial lesions who had negative cervical fluid-based cytology combined with positive HPV results were selected and analysed for severity of cervical lesions and HPV distribution. Among the patients with cervical lesions, 242 had a single HPV infection, and 128 cases had multiple infections. No significant difference was found between HPV single infection and multiple infections in both groups of patients with cervical lesions (P > 0.05). Furthermore, 137 had non-HPV 16 and 18, accounting for 37.30% of all the patients with cervical lesions. Among them, HPV 52, 58, and 33 infections were the most common at 38.69, 30.66 and 29.20%, respectively - significantly higher than other high-risk HPV types (P < 0.05). High-risk HPV testing is crucial in patients with negative cervical fluid-based cytology combined with positive HPV results. Patients with HPV 16 and 18 and those with simple HPV 52, 58, and 33 infections should undergo timely colposcopy.

Human papillomavirus DNA testing with the urine sample is not yet available: the accuracy of two distinct kits.

The aim of this study was to assess the results and efficiency of two real-time polymerase chain reaction procedures for detecting human papillomavirus utilizing urine samples. This study comprised 151 patients who had previously tested positive for human papillomavirus in their cervical samples. Two different commercial real-time polymerase chain reaction techniques were used for identification and genotyping human papillomavirus in urine specimens. The urine samples of 151 patients were evaluated via the Roche Cobas test, and the urine samples of 91 patients were also evaluated via the Qiagen test. The overall consistency of urine and cervical swab specimens for the identification of human papillomavirus in Roche Cobas and Qiagen tests were 44.8 and 44%, respectively. The rates of positive human papillomavirus results from urine samples were 57 and 70.3%, respectively. The overall concordance among Roche Cobas and Qiagen tests utilizing urine samples for human papillomavirus type 16/18 was 84.3% with a kappa value of 0.675, and for other high-risk-human papillomavirus, it was 75.60% with a kappa value of 0.535. Roche Cobas showed high concordance with Qiagen test. human papillomavirus positivity was not detected in all urine samples. It is still inappropriate to recommend the use of urine liquid biopsy for the accurate and reliable detection of human papillomavirus. Due to the lack of a standardized tool, the utilization of urine samples as a screening human papillomavirus test remains a challenge.

Prevalence and correlates of Human Papillomavirus infection in females from Southern Province, Zambia: A cross-sectional study.

Human papillomavirus (HPV) infection is strongly associated with cervical cancer with almost all cases being associated with the infection. Cervical cancer is the leading cause of cancer death among women in Zambia and the fourth leading cause of cancer death in women worldwide. However, there is limited data on the burden and associated factors of HPV in sub-Saharan Africa. This study therefore aimed to determine the prevalence and correlates of HPV infection in the Southern province of Zambia. This was a cross-sectional study conducted at Livingstone University Teaching Hospital (LUTH) among 4,612 women from different districts of the southern province being screened for HPV infection between September 2021 and August 2022. Demographic and clinical data were collected from an existing laboratory programmatic database. Multivariable logistic regression was used to estimate the factors associated with HPV infection. The study participants had a median age of 39 years [interquartile range (IQR) 30, 47]. The prevalence of HPV infection was 35.56% (95%CI). At multivariable analysis, the factors associated with a positive HPV result were younger age (adjusted odds ratio (AOR) 0.98; 95% confidence interval (CI) 0.98-0.99; p. value 0.001), having provider collected sample (AOR 2.15; 95%CI 1.66-2.79; p. value <0.001) and living with HIV (AOR 1.77; 95%CI 1.22-2.55; p. value <0.002). The prevalence of HPV in women in the southern province of Zambia is high, and likely influenced by age and HIV status. Additionally, the outcome of the HPV test is affected by the sample collection method. Therefore, there is a necessity to enhance HPV and cervical cancer screening, especially among people with HIV.

Factors influencing the intention to engage in cervical cancer preventive behavior in human papillomavirus-infected women: a cross-sectional survey.

This study investigated the influence of cervical cancer knowledge, human papillomavirus (HPV) knowledge, self-efficacy, and uncertainty on the intention to engage in cervical cancer preventive behavior in HPV-infected women. This descriptive correlational study was conducted among 129 adult women aged 20 to 65 years who received positive HPV results at a general hospital in Changwon, Korea. The dataset was analyzed using descriptive statistics, the independent t-test, analysis of variance, the Pearson correlation coefficient, and multiple regression. The mean score for the intention to engage in cervical cancer preventive behavior was high (4.43±0.65). This intention was significantly different according to age at first sexual intercourse (F=7.38, p=.001), HPV type (F=4.79, p=.010), vaccination (t=3.19, p=.002), and condom use (t=3.03, p=.003). The intention to engage in cervical cancer preventive behavior showed significant, weak-to-moderate positive correlations with HPV knowledge (r=.22, p=.012) and self-efficacy (r=.42, p<.001). Self-efficacy (β=.46, p<.001), first sexual intercourse at <20 years (β=.45, p<.001), first sexual intercourse at 20-24 years (β=.29, p=. 018), HPV high- and low-risk group infection (β=.26, p=.019), HPV high-risk group infection (β=.26, p=.026), and vaccination (β=.21, p=.007) significantly influenced the intention to engage in cervical cancer preventive behavior. These variables explained 34.6% of variance in intention. Study findings support the need to develop a program that effectively conveys accurate information about cervical cancer prevention to HPV-infected women and helps them enhance self-efficacy to boost the intention to engage in cervical cancer preventive behavior.

The Follow-Up Necessity in Human Papilloma Virus-Positive vs. Human Papilloma Virus-Negative Oral Mucosal Lesions: A Retrospective Study.

Human papilloma virus (HPV) is known as the main cause of cervical cancer. Data also indicate its role in head-neck cancer, especially oropharyngeal cancer. The correlation between high-risk HPV and oral cancer is still controversial. HPV-related lesions of the oral cavity are frequent and, in most cases, benign. The primary aim of this study was to establish if there is a different follow-up necessity between HPV-positive compared to HPV-negative oral lesions. The secondary aim was to evaluate the recurrence of HPV-related lesions. All patients who underwent a surgical procedure of oral biopsy between 2018 and 2022, with ulterior histopathological examination and HPV typing, were examined. A total of 230 patients were included: 75 received traumatic fibroma as diagnosis, 131 HPV-related lesions, 9 proliferative verrucous leukoplakia, and 15 leukoplakia. The frequency and period of follow-up varied in relation to HPV positivity and diagnosis. This study confirms what has already been reported by other authors regarding the absence of recommendations of follow-up necessity in patients with oral mucosal lesions. However, the data demonstrate that there was a statistically significant difference in the sample analyzed regarding the follow-up of HPV-positive vs. HPV-negative patients. It also confirms the low recurrence frequency of HPV-related oral lesions.

Clinical use of the Onclarity test with extended HPV genotyping and phenotyping in patients with suspected squamous intraepithelial lesions.

Human papillomavirus (HPV) is the most widespread virus with oncogenic potential that infects humans and there is a need to look for the most effective screening method among the population. Understanding the role of HPV in cervical dysplasia and viruses typing increased the usage of HPV-based cervical cancer screening tests using genotyping. We aim to assess the usefulness the Onclarity Test with extended genotyping and phenotyping of HPV in detecting cervical squamous intraepithelial lesions in 695 subjects who registered for regular cervical screening or due to abnormal LBC result or positive HPV results. Incidence of positive HPV depended significantly on biopsy outcome (p < 0.001). It was the highest for patients with HSIL (92.5%), lower for patients with LSIL (57.9%) and with HPV outcome of biopsy (50.0%). The sensitivity of positive HPV for detecting HSIL was equal to 92.50% (95% CI: 79.61%-98.43%), and specificity equalled 55.26% (95% CI: 43.41-66.69%). Sensitivity of HPV positive for any of 16, 18, 31, 45, 51 or 52 genotypes but not belonging to the P1, P2 or P3 group for detecting HSIL equalled 62.50% (95% CI: 45.80-77.27%), specificity equalled 72.37% (95% CI: 60.91-82.01%). The Onclarity test is characterised by high sensitivity and specificity in detecting CIN2+ lesions. Extended genotyping enables the identification of the most common oncogenic HPV types in the population. It can be used as a basic tool for secondary prevention or together with LBC.

Efficacy of Cobas HPV testing for predicting grade 2+ cervical intraepithelial neoplasia in a cancer prevention center and a gynecologic oncology clinic: A single-institution experience.

To evaluate the efficacy of Cobas human papillomavirus (HPV) testing to predict cervical intraepithelial neoplasia of grade 2 or higher (CIN2+), Cobas HPV testing results were correlated with follow-up biopsy in patients from Cancer Prevention Center (CPC) and Gynecologic Oncology Clinic (GOC) of The University of Texas MD Anderson Cancer Center. Institutional data for patients who underwent Cobas HPV and Papanicolaou (Pap) cytology cotesting from 2019 to 2020 were retrospectively reviewed. Surgical follow-up results were compared with Cobas HPV testing results in two populations. A total of 2226 patients, including 921 women (mean age, 55.2years) seen at the CPC and 1305 women (mean age, 49.3years) seen at the GOC, were included. Specimens from GOC patients had a significantly higher HPV positivity rate than did those from CPC patients (22.9% vs. 10.1%; p<.001). Cobas HPV testing was positive in all seven CPC patients with surgical follow-up results showing CIN2+. Among 36 GOC patients with CIN2+ lesions, five patients had HPV-/Pap+testing results. Although only seven CPC patients had CIN2+, Cobas HPV testing showed 100% sensitivity for predicting CIN2+ in this group. Sensitivity for CIN2+ was 86.5% in the GOC group, whereas 13.9% of GOC patients with CIN2+ had negative HPV testing results. Cobas HPV testing was highly efficacious for predicting CIN2+ lesions in the low-risk CPC population, which supports HPV primary screening for cervical cancer in low-risk populations. For high-risk patients, especially those with a history of CIN2+/cervical cancer, HPV/Pap cotesting may still be necessary to maintain a high clinical sensitivity for CIN2+.

Cytological features of human papillomavirus-infected immature squamous metaplastic cells from cervical intraepithelial neoplasia grade 2.

In reflex cytology, the presence of prominent nucleoli in immature metaplastic squamous cells (IM) may be underdiagnosed due to variations in interpretation. The aim of this study is to identify human papillomaviruses (HPVs) that infect IM clusters in cervical intraepithelial neoplasia 2 (CIN2) on Papanicolaou (Pap) smears to determine the cytological features of lesion-derived cells. Thirty-two patients with a simultaneous diagnosis of CIN2 on biopsy and high-grade squamous intraepithelial lesions (HSIL) on cytology as well as with IM clusters on HSIL smears were included. CIN2 tissues and HSIL and IM clusters on Pap smears were isolated by manual microdissection, and HPV types were identified by PCR-based genotyping. The nuclear area within the IM clusters was also measured. The median nuclear area of HPV-negative IM clusters was 48 μm2 , with a coefficient of variation (CV) of 0.20; those of HPV-positive clusters were 66 μm2 and 0.34, respectively. The cut-off values of the nuclear area and CV for HPV positivity were 62 μm2 and 0.25, respectively. IM clusters composed of cells with a nuclear area of more than twice that of neutrophils or cells with a wide variation in nuclear sizes are likely to be neoplastic cells caused by HPV.

Intracellular Toll-Like Receptors Modulate Adaptive Immune Responses in Head and Neck Cancer.

The percentage of head and neck cancer (HNC) positive for human papillomavirus (HPV) is unknown in most parts of India. How toll-like receptors (TLRs) affect the adaptive immune response in HNC is also mainly unknown. We here assessed the expressions of HPV DNA, p16, inflammation, and TLRs in oral squamous cell carcinoma (OC) and oropharyngeal squamous cell carcinoma (OPC). Patients with OC (n = 31) and OPC (n = 41), diagnosed during 2017-2018 at the Malabar Cancer Centre (tertiary cancer center), Kerala, India, were included in the study. Immunohistochemistry was performed on tumor specimens against p16, TLR3, TLR7, TLR8, TLR9, CD4, and CD8. Quantitate polymerase chain reaction for 14 high-risk HPVs (HPV16/18/31/33/35/39/45/51/52/56/58/59/66/68) was performed. Seven out of 31 OC (22.6%) were p16+ but only 3.2% (1/31) of OC were positive for HPV DNA. While 24.4% (10/41) of OPC were p16+, HPV DNA was found in only one P16+ OPC and in no P16- OPC. TLR3, TLR7, TLR8, and TLR9 were expressed both in OC and in OPC. The expression of TLR7 was significantly higher in OPC compared with OC. TLR8 expression was correlated with and TLR7 tended to be correlated with the inflammatory score in OPC (r = 0.56, p < 0.05 and r = 0.52, p = 0.08, respectively). In conclusion, the role of HPV in OC and OPC is minor, and p16 constitutes a poor biomarker for HPV positivity in Kerala, India. Intracellular TLRs are correlated with the degree of inflammation in OPC but not in OC and may potentially constitute a medical target in the therapy of HNC in the future.

Abstract A051: A conceptual framework for disclosure, intimacy, and sexual behaviors among Black women diagnosed with human papillomavirus

Abstract Purpose: Black women suffer disproportionately from Human papillomavirus (HPV) infection and related cancers, including greater associated post-diagnosis mortality. Little research and no frameworks, of which we are aware, have characterized the experiences of patients with a positive HPV diagnosis, including which factors contribute to disclosure of one’s HPV positive status, which has specific implications for intimacy with romantic partners, sexual behaviors, and the spread of HPV. Objective: To propose a conceptual framework regarding disclosure, intimacy with romantic partners, and sexual behaviors among Black women diagnosed with an HPV infection. Development: A working group including diverse perspectives in public health (e.g., infectious disease, women’s health, cancer health) conducted a review of eight existing public health, cancer health equity, and infectious diseases to identify frameworks relevant for our outcomes – i.e., communication about one’s disease status, partnership/relationship outcomes, and sexual health. Examples include Communication Privacy Management Theory, Politeness Theory, Objectification Theory, socioecological models, Maslow’s Hierarchy of Needs model, and models on social relationships and health, including those focused on stress processes. Framework: Our framework first characterizes HPV disclosure which is a multi-dimensional construct, representing the amount and type of information that is communicated to the partner. Multifaceted factors that contribute to disclosure include HPV knowledge, exposure to community stigma (e.g., sexual silence), self-efficacy for disclosure, and anticipated support from partner. These patient-level factors may not only contribute to disclosure, but also influence how HPV disclosure affects relationship outcomes (e.g., intimacy, sexual behaviors). Other theoretical moderators exist at multiple levels, including at the levels of the disclosure, partner, and relationship. At the level of the disclosure, the modality, amount, and type of information communicated may influence partner responsiveness and relationship outcomes (e.g., reduced intimacy, alternative sexual partners). At the partner level, knowledge of HPV, and exposure to community stigma can contribute to the partner’s response and relationship outcomes. At the relationship level, quality, values, and norms of the relationship, including trust, provision/receipt of emotional support, and communication norms, will also likely moderate the impact of disclosure on relationship outcomes. Emerging Research: This framework offers multiple venues for future cancer equity research. We will conduct participatory qualitative research to identify other relevant factors and pathways through which an HPV diagnosis may impact disclosure, intimacy, and subsequent sexual risk. We will subsequently conduct quantitative survey research to test associations and offer targets for future cancer health equity interventions.

Prevalence of Human Papillomavirus Infection and Cervical Abnormalities among Women Attending a Tertiary Care Center in Saudi Arabia over 2 Years.

Human papillomavirus (HPV) genotype distribution varies according to the assessment method and the population targeted. This study aimed to assess HPV infection prevalence in women aged 23 to 82 with abnormal cytology attending King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, using retrospective data collected from January 2021 to December 2022. Cytological distribution included 155 samples of atypical squamous cells of undetermined significance (ASCUS) (n = 83), low-grade squamous intraepithelial lesion (LSIL) (n = 46), high-grade squamous intraepithelial lesion (HSIL) (n = 14), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) (n = 10), and squamous cell carcinoma (SCC) (n = 2). All samples were submitted to HPV detection and genotyping using Xpert HPV assay specimens. The most prevalent epithelial abnormalities were ASCUS (53.50%). Positive HPV infection results were observed in 52.9% of the samples. The highest prevalence of HPV genotypes, accounting for 31%, was attributed to the other high-risk genotypes, including 31, 33, 35, 39, 51, 52, 56, 58, 59, 66, and 68, followed by high-risk genotype 16, which counted in 11.60% of cases. Individuals who tested positive for HPV 16 were at a high risk of ASC-H, HSIL, and LSIL. Those testing positive for HPV 18-45 exhibited an elevated risk of LSIL, and those with positive results for other high-risk HPV genotypes were at an increased risk of ASCUS and LSIL, suggesting a low oncogenic potential. The results suggest that the percentage of association between samples with abnormal cervical presentation and negative high-risk HPV diagnosis is noticeably increasing. This underscores the need for effective screening programs and an understanding of the impact of specific HPV genotypes on cervical abnormalities.

Epidemiology of genital human papillomavirus infections in sequential male sex partners of young females

ObjectivesCouple-based studies have considered human papillomavirus (HPV) transmission between current heterosexual partners (male↔female). Using data from young women and their sequential male partners, we analysed HPV transmission from upstream sexual partnerships (male 1↔female) to downstream sex partners (→male 2). MethodsAmong 502 females enrolled in the HPV Infection and Transmission among Couples through Heterosexual activity study (2005–2011, Montréal, Canada), 42 brought one male sex partner at baseline (male 1) and another during follow-up (male 2). Female genital samples, collected at six visits over 24 months, and male genital samples, collected at two visits over 4 months, were tested for 36 HPV types (n = 1512 detectable infections). We calculated observed/expected ratios with 95% CIs for type-specific HPV concordance between males 1 and 2. Using mixed-effects regression, we estimated ORs with 95% CIs for male 2 testing positive for the same HPV type as male 1. ResultsDetection of the same HPV type in males 1 and 2 occurred 2.6 (CI 1.9–3.5) times more often than chance (29 instances observed vs. 10.95 instances expected). The OR for male 2 positivity was 4.2 (CI 2.5–7.0). Adjusting for the number of times the linking female tested positive for the same HPV type attenuated the relationship between male 1 and 2 positivity, suggesting mediation. ConclusionsHigh type-specific HPV concordance between males 1 and 2 confirms HPV's transmissibility in chains of sequential sexual partnerships. HPV positivity in an upstream partnership predicted positivity in a downstream male when the linking female partner was persistently positive.

Outcome and associated factors of high-risk human papillomavirus infection without cervical lesions.

To study the outcome of human papillomavirus (HPV) infection in women with cervical pathology results of non-cervical intraepithelial neoplasia (CIN) or cervical cancer and positive high-risk HPV test, as well as analyze the associated risk factors affecting the outcome of infection. To investigate the outcome of high-risk (HR)-HPV infection in the female genital tract and analyze the associated risk factors affecting their outcome, a total of 196 women with positive HR-HPV test results and non-CIN or cervical cancer cervical pathology results were selected for follow-up at the Cervical Disease Clinic of the Obstetrics and Gynecology Hospital, Zhejiang University School of Medicine from January 2017 to March 2020. The follow-up interval was every 6 months, and both cervical cytology (TCT) and HR-HPV testing were performed at each follow-up visit. If the cervical cytology results were normal upon recheck and the HR-HPV test was negative, the woman was considered to be cleared of the HPV infection and was entered into the routine cervical screening population. When the repeat HR-HPV test remained positive after 6 months, the woman was defined as having a persistent HR-HPV infection. If HR-HPV persisted but the TCT results were normal, follow-up was continued. If HR-HPV persisted and the TCT results were abnormal, a colposcopy-guided biopsy was performed immediately. In this situation, if the histological results were still non-CIN or cervical cancer, the follow-up was continued. If the histological results confirmed the development of CIN or invasive cancer, then enter another study follow-up to further track its development and outcome, and the woman commenced the treatment process. The HPV infection clearance time was analyzed by the Kaplan-Meier method, and the comparison of the HPV clearance rate and infection clearance time between each of the different groups was performed using aχ2 test or Fisher's exact test, as appropriate. After the univariate analysis, several significant factors were included in the Cox model and independent risk factors were analyzed. A total of 163 women were enrolled in this study. The median age was 40.0 years (22-67 years) and the median follow-up time was 11.5 months (6-31 months). The spontaneous clearance rate of HR-HPV infection was 51.5%, and the median time to viral clearance was 14.5 months. Age and the initial viral load were high risk factors affecting the spontaneous clearance of HR-HPV infection. The factors significantly associated with HPV clearance rate and time to HPV clearance consisted of menopause and full-term delivery (P < 0.05). In women with normal or low-grade lesions on the cell smear, the spontaneous clearance rate of HR-HPV infection was 51.5% and the time to clearance was 14.5 months. Age and the initial viral load were independent associated factors affecting the spontaneous clearance of HR-HPV infection in the female genital tract. These findings suggest that non-young women or those with high viral loads have a higher rate of persistent HR-HPV infection. Thus, intensive screening should be recommended.
