[PMID: 33847377 DOI: 10.1002/jmv.27012] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 02/08/2021] [Accepted: 04/11/2021] [Indexed: 12/16/2022]
Abstract
We aimed to study the infection status and distribution of human papillomavirus (HPV) in Yangzhou City to provide precise guidance for the prevention and treatment of cervical cancer in this area. Reproductive tract secretions were collected from patients admitted at Subei People's Hospital over the past 3 years. Fifteen high-risk HPV (HR-HPV) genotypes were analyzed by fluorescent polymerase chain reaction. The positive rate of HR-HPV in 34 420 subjects was 23.56%. There was no significant difference in the rate of overall infection between males and females (χ 2 = 0.04; p = 0.952 > 0.05). The five genotypes with high infection rates in the population were HPV52, HPV58, HPV16, HPV51, and HPV39. Single infection was found to be dominant, primarily with the HPV52 genotype. The infection rate was higher in patients less than 20 years old and more than 60 years old. Most patients with cervical intraepithelial neoplasms 2/3 and cervical cancer were infected by HPV16, followed by those infected by HPV52 and HPV58. There was a significant difference in the infection rate of HPV16 among patients with different cervical lesions (χ 2 = 31.660; p < 0.01), and the infection rate of HPV16 was higher in patients with cervical cancer than in healthy individuals. Single infection was dominant among the study patients with HPV infection in Yangzhou city. There was no significant difference in infection rate and genotype distribution between males and females. The infection rate in young and old women was higher, and the rate increased with age (>20 years).

Abstract
Human papillomavirus (HPV) can cause various diseases; low-risk strains can cause
genital warts, whereas high-risk strains can cause cervical cancer and cancer of
the vulva in women and cancers of the penis, anus, and oropharynx in men.
Although HPV affects men, literature has reported that the prevalence of HPV
vaccination is far lower among men than among women. Few studies have examined
perceptions and acceptability of the HPV vaccine among men, particularly in
Chinese communities. In this study, the acceptability of the HPV vaccine to men
was investigated using Hong Kong men as a case group. A qualitative research
approach was adopted. Thirty-nine men were purposively sampled for the in-depth
individual semistructured interviews from June to October 2017 to investigate
their perceptions of the HPV vaccine and the barriers for them to receive the
vaccination. Limited knowledge and awareness of HPV-related issues, low
perceived risk of HPV infection, perceived association between HPV vaccine and
promiscuity, and lack of accessible official information on HPV-related topics
were identified as the key barriers. These barriers intermingled with the
sociocultural environment, cultural values of sexuality, and patriarchal gender
values. HPV vaccine is shown to be socially constructed as a vaccine for women
exclusively and for promiscuity. The participants were discouraged from
receiving HPV vaccination because of its signaling of socially deviant
promiscuity. Cultural taboo on sex served as a social oppression of open
discussion about HPV vaccine and affected the participants’ perceived need of
vaccination. Perceived insignificance of reproductive organs also influenced the
participants’ perceived need of vaccination.

Estimating incidence rates of grouped HPV types: A systematic review and comparison of the impact of different epidemiological assumptions. PAPILLOMAVIRUS RESEARCH (AMSTERDAM, NETHERLANDS) 2019; 8:100187. [PMID: 31600572 PMCID: PMC6804437 DOI: 10.1016/j.pvr.2019.100187] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 10/04/2019] [Accepted: 10/06/2019] [Indexed: 01/01/2023]
Abstract
BACKGROUND Some studies on human papillomavirus (HPV) provide not only type-specific incidence rates (IR), but also IRs of HPV groupings (e.g. the nonavalent grouping). We made an inventory of the different approaches used to calculate such IRs and assessed their impact on the estimated IRs of HPV groupings. METHODS We performed a systematic review assessing all approaches used in literature to estimate IRs. Subsequently we applied these approaches to data of a Dutch cohort study on HPV in men who have sex with men (H2M). IRs were estimated for six different HPV groupings. RESULTS The systematic review yielded six different approaches (A-F) for estimating the IRs, varying in exclusion criteria at baseline, and the definitions of an incident event and person-time. Applying these approaches to the H2M dataset (n = 749), we found differences in the number of participants at risk, number of incidents events, person-time, and IR. For example, for the nonavalent grouping, depending on the approach chosen, the IR varied between 3.09 and 6.54 per 100 person-months. CONCLUSION In published studies different epidemiological assumptions are used to estimate IRs of grouped HPV types, leading to widely differing estimates of IRs. IRs between different studies may therefore not be comparable.

Abstract
Human papillomavirus (HPV) is the most common pathogen of sexually transmitted disease worldwide. While HPV is responsible for low-grade benign lesions in the anogenital area such as condyloma acuminatum, it is also strongly associated with cervical, anal, vulvar/vaginal, and penile carcinomas. In addition to being an oncogenic virus, HPV causes a substantial socioeconomic burden due to the recurrence of benign lesions, the lack of a definitive treatment option that provides a complete cure, and the high cost of treatment. The global incidence of HPV infection is rising, especially among young and sexually active individuals; as a result, in recent years these infections have also become increasingly conspicuous in urology practice, both as incidental findings and primary complaints. The aim of this review is to evaluate the pathogenesis, diagnosis, and treatment modalities of HPV infections in light of the current literature from the urologist's perspective.

Abstract
Cancer is a leading cause of death among people living with HIV/AIDS (PLWHA). We conducted a systematic review and meta-analysis to evaluate prevalence of cancer risk factors among Chinese PLWHA based on 102 articles. Random effects meta-analysis was used to calculate the summary prevalence estimate (sPrev) and 95% confidence interval (CI) for each cancer risk factor by demographic group. Overall, the sPrev for each risk factor among Chinese PLWHA was: 41.1% (95% CI: 35.3–46.9%) for current smoking; 30.3% (95% CI: 23.3–37.4%) for current alcohol consumption; 24.4% (95% CI: 14.7–30.2%) for overweight and obesity; 12.5% (95% CI: 10.6–14.3%) for hepatitis B virus infection; 29.1% (95% CI: 23.6–34.5%) for hepatitis C virus infection; 33.9% (95% CI: 24.3–43.5%) for high-risk human papillomavirus infection from cervical samples and 78.6% (95% CI: 69.4–87.7%) from anal samples; 2.7% (95% CI: 0.7–4.7%) for Epstein-Barr virus (EBV) immunoglobulin M (IgM) positivity, 94.7% (95% CI: 90.7–98.8%) for EBV IgG positivity and 25.6% (95% CI: 12.4–38.8%) for EBV DNA positivity; 14.9% (95% CI: 12.4–17.4%) for human herpes virus 8 infection. The prevalence of major cancer risk factors was high among PLWHA in China, suggesting an urgent need for interventions to reduce cancer risk in this high-risk group.

Abstract
The natural history of oral human papillomavirus (HPV) infection which is linked with the increased incidence of oropharyngeal squamous cell cancer (OPSCC) has been incompletely studied. Oral swab specimens and questionnaire data were obtained bi-annually for up to 6 visits from 4314 healthy adults aged 25-69 in rural Anyang, China. HPV infection status was evaluated with PCR-based sequencing. Participants with at least two consecutive valid HPV results within the study period were included in the incidence and clearance analysis. Among 3289 participants included in this analysis (median follow-up time 18.3 months), incidence rates of mucosal HPV, oncogenic mucosal HPV and cutaneous HPV were 0.53 (95% CI: 0.39-0.73), 0.30 (95% CI: 0.20-0.46), and 4.17 (95% CI: 3.70-4.70) per 1,000 person-months respectively. Most newly acquired infections were cleared within one year. Recent practice of oral sex increased the risk of incident infection with mucosal HPV (Adjusted HR, 5.03; 95% CI, 1.16-21.73) and oncogenic mucosal HPV (Adjusted HR, 10.13; 95% CI, 2.14-48.06). Newly acquired oral mucosal HPV infections are rare and most are cleared within one year in rural Chinese. This study expands understanding of the natural history of oral HPV in countries with a lower incidence of HPV-OPSCC.

Abstract
This study aimed to investigate the presence of human papillomavirus and Epstein-Barr virus in male lichen sclerosus patients. We extracted DNA from formalin-fixed paraffin-embedded foreskin tissue blocks of 47 male LS patients and 30 healthy men and performed real-time PCR test to detect HPV and EBV. None of the 47 LS patients and 30 healthy men had detectable HPV infection. EBV was detected in 18 LS patients (38.3%) and four healthy men (13.3%), the difference is significant (P < 0.05). Tissue blocks with significant inflammatory reaction tend to have higher EBV load. HPV has no significant relationship with LS. Male LS patients have higher EBV infection rate, but the role of EBV in the pathogenesis of LS needs further investigate.

Abstract
PURPOSE This paper reports the results of a clinical study that tested the effect of systemic treatment with the botanical product Gene-Eden-VIR/Novirin on the clearance rate (also called time to clearance) of the human papillomavirus (HPV). The study compared the clearance rate in treated and untreated individuals suffering from a symptomatic HPV infection. The data on the untreated individuals were obtained by reverse engineering of the Kaplan-Meier figures in five published papers. MATERIALS AND METHODS The study included 59 treated participants. All participants were suffering from a symptomatic HPV infection prior to the commencement of treatment. The treatment was one to four capsules of Gene-Eden-VIR/Novirin per day. The duration of treatment was 2-12 months. The study included five groups of external controls with diverse characteristics. RESULTS The mean time to clearance in Gene-Eden-VIR/Novirin-treated individuals was 5.1 months or 151.5 days (95% CI: 4.2-5.9 months or 95% CI: 125.7-177.3 days, respectively). The median time to clearance was 3.5 months. The mean time to clearance in the five untreated groups ranged from 6.9 to 20.0 months (P<0.0001 for the difference between treatment group and each untreated group). Also, 100% of the participants in the treatment group were HPV free at the end of 12 months vs 53%, 52%, 65%, 20%, and 77% in the untreated control groups. The treated participants reported no adverse experiences. CONCLUSION This clinical study has two major contributions. First, it showed that systemic treatment with the natural Gene-Eden-VIR/Novirin decreased the time to HPV clearance, increased the percentage of HPV-free individuals, and caused no adverse experiences in individuals suffering from a symptomatic HPV infection. Since there are no other systemic treatments for symptomatic HPV infections, this study presents highly valuable information on the clinical effects of the first treatment in this category. Second, the study presents a new method for conducting clinical studies that addresses one of the major deficiencies associated with the practice of the randomized controlled trial method.

Abstract
Oncogenic human papillomavirus (HPV) infection is a cause of many anogenital cancers in women and men; however, there is little research on HPV prevalence and risk factors that includes both women and men from the same population. A total of 4687 participants, including 2378 women and 2309 men aged 18–55 years old from the same community, were enrolled in the study in Liuzhou, China. Exfoliated cells were collected from the participants from different anatomic sites and were tested for 13 oncogenic and 3 non-oncogenic HPV types. The prevalence of any oncogenic HPV type was higher in women than in men (18.7% vs 9.4%, P<0.001), whereas the prevalence of HPV 6 and 11 infection was similar (1.4% vs 1.2%, P=0.6832). HPV 52, 58, 16, 39 and 18 were the five most prevalent types in both sexes. Sexual and hygienic behaviors were associated with HPV infection in both women and men. We found that oncogenic HPV DNA detection is more prevalent in women than in men in China, whereas the prevalence of HPV 6 and 11 is similar in both sexes. The data indicate that the interaction of host and virus might be different among high- and low-risk HPV types.

Abstract
Background The effectiveness of health interventions can be impaired by low socio-economic status and poor living conditions of the target population. However, the specifics of this problem in rural China are still unclear, and appropriate strategies should be explored. Methods In 2013, we conducted a questionnaire-based investigation among 410 participants from a population-based esophageal cancer cohort study in rural Anyang, China. Information regarding their demographic characteristics, levels of exposure to four health-risk behaviors, including smoking, alcohol consumption, risky dietary behaviors and poor hygiene, as well as willingness to change these behaviors, and data on potential predictors of willingness to change behaviors were collected. Results In this study, 33.3% (23/69), 25.0% (13/52), 60.7% (68/112) and 62.2% (237/381) of respondents reported that they were willing to change smoking, alcohol consumption, risky dietary behaviors and poor hygiene, respectively. Older people had higher exposure levels and less willingness to change these four health-risk behaviors. The levels of these four health-risk behaviors were negatively associated with willingness to change, while faith in people and behavioral change in surrounding people increased willingness to change risky behaviors. Conclusions In behavior-intervention-based health-promotion programs in rural China, the elderly and highly exposed populations should be the most difficult part and community- or household-based intervention would be more efficient.

Prevalence and Associated Risk Factors of Human Papillomavirus in Healthy Skin Specimens Collected from Rural Anyang, China, 2006-2008. J Invest Dermatol 2016; 136:1191-1198. [PMID: 26916390 DOI: 10.1016/j.jid.2016.02.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2015] [Revised: 02/02/2016] [Accepted: 02/05/2016] [Indexed: 12/20/2022]
Abstract
Skin infections with cutaneous human papillomavirus (HPV) have been linked to the development of non-melanoma skin cancer, in which mucosal HPV may also play a crucial role. However, systematic investigations of the distribution and associated factors of HPV infection in healthy skin of the general population are scarce. HPV DNA from palmar exfoliated cells of 2,087 individuals was detected by FAP6085/64 and SPF1/GP6+ primers followed by sequencing. A total of 338 papillomavirus types were detected, with HPV-3, HPV-57, and HPV-49 being the most dominant types. The overall prevalence for HPV DNA on skin was 79.92% and for alpha-, beta-, and gamma-HPV were 27.07%, 38.76%, and 29.56%, respectively. Having multiple lifetime sexual partners (adjusted odds ratio 1.60), being a migrant worker (adjusted odds ratio 2.05, reference: farmers), and frequent bathing (Ptrend = 0.001) were associated with alpha-HPV DNA presence. Advancing age increased the detection risk of beta-HPV (Ptrend = 0.001). Higher education (Ptrend = 0.017) and frequent bathing (Ptrend = 0.001) were positively related to gamma-HPV positivity. This study demonstrates that alpha-HPV commonly exists on healthy skin of the general population in rural China, and alpha- and gamma-HPV infections are related to certain behaviors, different from beta-HPV infection. These findings are crucial to better understanding the biology of HPV infection and may be suggestive of the potential transmission of these viruses.

Abstract
The acceptability of HPV vaccination among university students in China is not well understood. Our study was of cross-sectional study design. We collected a questionnaire about socio-demographic characteristics, knowledge of, attitude toward and acceptability of HPV vaccination. A total of 351 students were included in data analyses, among whom 47.6% were males and 70.0% aged 19-21. Only 10.3% had previously heard of HPV and 5.4% HPV vaccine. Male and female students were equally likely to accept HPV vaccine (71.8 vs 69.4%, p = 0.634) and recommend it to sexual partners (73.1 vs 76.7%, p = 0.441). The great majority of students could only afford RMB 300 (USD 50) or less for HPV vaccination. HPV vaccination acceptance was associated with being in year-one (Adjusted odds ratio (AOR) = 3.78, 95% confidence interval (CI): 2.12-6.75), being from a key university (AOR = 1.88, 95%CI: 1.07-3.31), having heard of HPV-related morbidities (AOR = 1.88, 95% CI: 1.05-3.35), being concerned about HPV-related morbidities (AOR = 2.23, 95% CI: 1.16-4.27) and believing the vaccine should be given before first sexual contact (AOR = 2.44, 95% CI: 1.38-4.29). Female students were more likely to anticipate a late uptake of HPV vaccination (p = 0.002). The relatively lower levels of HPV knowledge but higher levels of vaccine acceptance among undergraduates highlighted the need for education on the roles of sexual behaviors in HPV transmission.

Abstract
HPV transmission dynamics have rarely been studied in the general population, especially in China. We followed the genital HPV infection status of both partners in 874 couples aged 25-65 years from rural China for up to 7 bi-annual visits during 2009-2013. The positive HPV concordance and transmission rate for partners in a couple were evaluated and relevant risk factors were assessed. The concordance of any, oncogenic, and non-oncogenic HPV was 15.52%, 16.18% and 10.41%, respectively. Male-to-female transmission rate was 7.11, 12.13 and 4.77/1000 person months for any, oncogenic and non-oncogenic HPV respectively. The female-to-male transmission rate was 5.56, 2.37, and 17.01/1000 person months for any, oncogenic and non-oncogenic HPV respectively. The risk of male-to-female transmission was significantly higher than that of female-to-male transmission for oncogenic types. However, for non-oncogenic types, the risk of male-to-female transmission was significantly lower than that of female-to-male transmission. Younger couples, persistent infection with HPV, higher numbers of sexual partners and higher frequency of sexual intercourse were positively associated with HPV transmission in couples. Our results indicate that men in rural China play a more important role than men in western populations as a source of cervical oncogenic HPV infection in women.
