ObjectiveHuman papillomavirus (HPV) surveillance is important to monitor the effectiveness of national HPV vaccination programmes. Positivity of HPV in urine in men varies with different sampling methods. We aimed to determine the positivity for detection of HPV-6/11 in urine samples among men in relation to the position of genital warts and circumcision status.MethodWe analysed stored chlamydia-positive urine specimens in young heterosexual men aged less than 25 years attending Melbourne Sexual Health Centre, Australia, between 2004 and 2015, for HPV genotypes. Positivity of HPV-6/11 and high-risk genotypes were stratified according to the position of genital warts and circumcision status. Positivity of HPV-6/11 was calculated using diagnosis of warts as the gold standard. Warts were classified as proximal penile warts from suprapubic area to midshaft of penis, and distal penile warts from distal shaft of penis to meatus.ResultsOf the 934 specimens, 253 (27.1%) men were positive for any HPV and 82 men (8.8%) had genital warts. The ORs of HPV-6/11 detection in urine were 4.63 (95% CI: 1.68 to 12.78) and 40.20 (95% CI: 19.78 to 81.70) times higher among men who had proximal penile warts and distal penile warts, respectively, compared with men who did not have genital warts. Circumcised men were less likely to have high-risk HPV (OR 0.31; 95% CI: 0.14 to 0.65) than uncircumcised men. Uncircumcised men were more likely to have distal penile warts than circumcised men (OR 8.22; 95% CI: 1.34 to 337.46).ConclusionPositivity of HPV-6/11 in urine increases greatly in men with distal penile warts. Circumcised men are less likely to have distal penile warts, any HPV or high-risk HPV detected. Urine is likely to be an alternative sampling method for HPV-6/11 surveillance programme in men in countries with low circumcision rates.

Herd Protection

Australian-born women aged ≤32 years were eligible for the free female human papillomavirus (HPV) vaccination program introduced in 2007. A total of 1165 heterosexual couples attending the Melbourne Sexual Health Centre between 2011 and 2014 were included in this analysis. Findings showed the odds of having penile warts was 0.52-fold lower among men who had a female partner aged ≤32 years compared with men who had a female partners aged >32 years. This suggests men would have received herd protection from their female partners and hence they are at lower risk of acquiring genital warts.

Second Peak

Background The prevalence of human papillomavirus (HPV) at the cervix varies with age, peaking following sexual debut and declining thereafter in most populations. In some populations, a second peak is observed. Here we describe the prevalence of HPV at the cervix among Australian women before the commencement of the HPV vaccination program. Methods: Women aged 15 to 60 years attending health services for cervical screening between 2005 and 2008 were invited to participate. Liquid based cervical specimens were tested for 37 types of HPV using linear array. The percentage and 95% confidence interval of women with any type of HPV, any of 13 high risk HPV types, and with vaccine-preventable HPV types (types 6, 11, 16 and 18) were estimated in 5-year age bands. Results: Among 1929 women aged 15–60 years, HPV prevalence peaked at 64% at age 15–20 years, then declined gradually to 12% at age 41–45 years, whereafter it rose to 19% in women 51–55 years then returned to 14% in 56–60 year olds. Prevalence curves were similar for high-risk HPV types and vaccine-targeted HPV types 6, 11, 16 and 18 and when results were restricted to women with only normal cytology. Conclusions: The shape of the prevalence curve we observed is similar to those from other Western populations. Variation in prevalence curves is likely due to differences in sexual behaviour between populations and over time, reactivation of HPV during perimenopause, and possibly the presence of cervical screening programs. These data are the first such data from the Oceania region.

PURPOSE Cervical cancer is the leading cause of mortality by cancer in sub-Saharan Africa. The human papillomavirus (HPV) infection is recognized as a necessary and sufficient cause for cervical cancer. Population-specific estimates of HPV prevalence in the Democratic Republic of the Congo (DRC) are unknown. This study aims to estimate the prevalence of HPV and identify predominant genotypes circulating in Kinshasa, DRC. METHODS Between July 2015 and July 2017, women were invited to attend a screening program at Mont-Amba Health Centre in Kinshasa. Cervical specimens were collected using the Preservcyt medium. HPV DNA testing was performed for all specimens using real-time polymerase chain reaction. RESULTS During the 2-year period, a total of 1,870 women age 25 to 82 years were screened. The mean age was 46 years (± 11.4 years). The overall HPV prevalence was 28.2% (95% CI, 26.1% to 30.3%). High-risk HPV prevalence was 24.8% (95% CI, 22.8% to 26.8%). Women younger than 30 years had the highest overall HPV prevalence (42.2%; 95% CI, 34.7% to 49.9%). A second peak of prevalence was observed in women age 60 years and older. HPV68 (5.5%; 95% CI, 4.5% to 6.6%) was the most prevalent HPV type. CONCLUSION The distribution of HPV genotypes among women in our population was different compared with other world regions. A key finding was that HPV68 was the most prevalent high-risk HPV genotype. These findings highlight the need for the determination in our population of the etiologic fraction of different HPV types in invasive cervical cancers.

Abstract Background Understanding the source of newly detected human papillomavirus (HPV) in middle-aged women is important to inform preventive strategies, such as screening and HPV vaccination. Methods We conducted a prospective cohort study in Baltimore, Maryland. Women aged 35–60 years underwent HPV testing and completed health and sexual behavior questionnaires every 6 months over a 2-year period. New detection/loss of detection rates were calculated and adjusted hazard ratios were used to identify risk factors for new detection. Results The new and loss of detection analyses included 731 women, and 104 positive for high-risk HPV. The rate of new high-risk HPV detection was 5.0 per 1000 woman-months. Reporting a new sex partner was associated with higher detection rates (adjusted hazard ratio, 8.1; 95% confidence interval, 3.5–18.6), but accounted only for 19.4% of all new detections. Among monogamous and sexually abstinent women, new detection was higher in women reporting ≥5 lifetime sexual partners than in those reporting <5 (adjusted hazard ratio, 2.2; 95% confidence interval, 1.2–4.2). Conclusion Although women remain at risk of HPV acquisition from new sex partners as they age, our results suggest that most new detections in middle-aged women reflect recurrence of previously acquired HPV.

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

In developing countries, cervical cancer is the most common cause of cancer related to mortality in women. But the epidemiology of human papillomavirus (HPV) in different areas of Bangladesh is largely unknown both in risk groups and in the general population. The objective of the present study was to determine the risk factors associated with having HPV and the prevalence of high-risk HPV types among women with highrisk behaviour and to assess its potential impact on preventive strategies as the sex workers are at increased risk for sexually transmitted infections (STI), HPV and hence cervical cancer. Cervical swab from 293 sex workers in Dhaka City between August and September 2003 and between February 2005 and May 2006 were screened for HPV DNA using an HPV short fragment (E6) polymerase chain reaction (PCR) based assay. HPV positive samples were genotyped with nested multiplex polymerase chain reaction (NMPCR) for the highrisk types. The overall HPV prevalence in sex workers was 75.8%, whereas for the high risk type it was 49.8%. Prevalence of single genotype and multiple types of HPV was 33.1 and 16.7% respectively. The most prevalent high-risk HPV types, in order of prevalence rate, were HPV16, HPV18, HPV58, HPV45, HPV31 and HPV33. Both HPV 16 and HPV 18 were present in 21% of the cases. Targeting HPV 16 and 18 with prophylactic vaccines could possibly have an important impact on the incidence of invasive cervical carcinoma in this group of women. Primary prevention and cervical cancer screening programmes should be optimized more and run yearly among the general population. It is proposed to screen sex workers when they enter prostitution regardless of their age.

Almost all cervical cancers are associated with human papillomavirus (HPV); however, the majority of women infected with this virus do not develop cervical cancer. Therefore, new markers are needed for reliable screening of cervical cancer, especially in relation to HPV infection. We aimed to identify potential microRNAs that may serve as diagnostic markers for cervical cancer development in high-risk HPV-positive patients. We evaluated the microRNA expression profiles in 12 cervical tissues using the hybridization method and verified them by quantitative polymerase chain reaction (qPCR). Finally, we evaluated the effects of HPV16 oncoproteins on the expression of selected microRNAs using cervical cancer cells (CaSki and SiHa) and RNA interference. With the hybridization method, eight microRNAs (miR-9-5p, miR-136-5p, miR-148a-3p, miR-190a-5p, miR-199b-5p, miR-382-5p, miR-597-5p, and miR-655-3p) were found to be expressed differently in the HPV16-positive cervical cancer group and HPV16-positive normal group (fold change ≥ 2). The results of qPCR showed that miR-148a-3p, miR-190a-5p, miR-199b-5p, and miR-655-3p levels significantly decreased in the cancer group compared with the normal group. Upon silencing of HPV16 E5 and E6/E7, miR-148a-3p levels increased in both cell lines. Silencing of E6/E7 in SiHa cells led to the increase in miR-199b-5p and miR-190a-5p levels. Three HPV16 oncoproteins (E5, E6, and E7) downregulate miR-148a-3p, while E6/E7 inhibit miR-199b-5p and miR-190a-5p expression in cervical carcinoma. The three microRNAs, miR-148a-3p, miR-199b-5p, and miR-190a-5p, may be novel diagnostic biomarkers for cervical cancer development in high-risk HPV-positive patients.
