Human papillomavirus (HPV) infection is one of the causes of cervical cancer which is preventable. The study was a cross-sectional study with the objective was to determine the Human papillomavirus (HPV) vaccination coverage among working women. A total 236 educated working women were selected purposively from different working places in Dhaka city. A pretested semi- structured questionnaire was used for data collection. The knowledge was assessed by using modified Blooms cut off points which was developed with cervical cancer and vaccine knowledge related questions. The study result revealed that among 236 working women 71.2% knew about the risk factor of cervical cancer. It was found that 92.8% knew about the way of prevention of cervical cancer respectively. The overall knowledge on cervical cancer and vaccine was found to be having good knowledge 21.2%, satisfactory knowledge 41.9% and poor knowledge 36.9%. Out of the total working women only 5.1% had HPV vaccination coverage. Reason behind non vaccinations, 50% mentioned had no knowledge about vaccine, 35.3% mentioned can’t decide and 8.9% mentioned high cost of vaccine. Significant association has been observed in between vaccination coverage with over all knowledge of cervical cancer (p value .04). It may be concluded that HPV vaccination coverage is very low which needs awareness program on this issues through mass media, educational session, counseling and so on to reduce human papillomavirus associated cancers as well as economic burden.

Sex With Men

Background: Despite the insupportable burden caused by the human papillomavirus (HPV) and high vaccine acceptability, vaccination programs are not currently available for men who have sex with men (MSM). We aimed to assess HPV infection by examining the willingness for vaccination among MSM and cost-effectiveness of the Chinese 2-valent HPV vaccine.Methods: We recruited MSM in Shenyang, China between July and December 2020 to conduct anal HPV testing and an online survey regarding HPV-related knowledge and vaccine acceptability. We performed a cost-effectiveness analysis to evaluate the incremental cost-effectiveness ratios (ICERs) of the Chinese 2-valent HPV vaccine.Results: A total of 234 participants completed the online survey; of those, 203 were successfully tested for HPV. The median age was 30 years [interquartile range (IQR): 23–38 years]. Most participants had at least undergraduate education (136/234, 58.1%). The acceptability rate for the free HPV vaccine was 57.7% (135/234). The prevalence of HPV types 16 and 18 was 14.9% (18/121) and 26.8% (22/82) in the willing and unwilling to vaccinate groups, respectively (P > 0.05). The prevalence of high-risk HPV among participants aged <30 and ≥50 years was 48.6 and 38.9%, respectively. Using the Chinese per capita gross domestic product (GDP) as a threshold, the Chinese 2-valent HPV vaccine would be a “very cost-effective” strategy, with an ICER value of USD 4,411. This evidence showed that the Chinese 2-valent HPV vaccine was more cost-effective than other imported vaccines.Conclusions: Targeted strategies should be utilized in MSM with different rates of vaccine acceptability. A pilot HPV vaccination program based on the Chinese 2-valent HPV vaccine for MSM is urgently warranted to reduce the burden of HPV and anal cancer.

Abstract Background Human papillomavirus (HPV) infection is a public health problem in Africa because of its frequency and its various consequences in both men and women. In Burkina Faso, there is little data on the carriage of HPV infection in male subjects. This study aimed to determine the carriage of HPV infection in male subjects in Ouagadougou, Burkina Faso.Methods This was a cross-sectional study conducted from December 2015 to September 2016. During this study period, a total of 124 male subjects who gave informed consent were recruited as part of a fertility assessment. Semen samples were analyzed by Real- Time PCR using Real TM Quant High Risk Screen HPV kit to detect 14 high-risk HPV genotypes. The Chi square test was used for comparisons.Results Of the 124 male subjects, 22 were positive for at least one high-risk HPV, with a prevalence of 17.7%. HPV 56 was the most represented genotype with a frequency of 20%, followed by HPV 39 (11%) and HPV 68 (11%), HPV 16 (8%). The genotypes HPV 18, HPV33, HPV35, HPV51 and HPV52 also had the same frequency of 6% each and the HPV 31, 45, 59 and 66 had the same frequency of 3% each. Of the 22 positive cases, 10 were multiple infections. Spermocytogram of patients showed at least one abnormality in 87.9% of cases. Necrozoospermia and oligozoospermia were the most abnormalities observed with 42% and 40% respectively followed by asthenospermia (18%); teratozoospermia (16%) and azoospermia (14%).Conclusion This study showed that like women, men are infected by HPV with a relatively high prevalence. In addition, the predominant genotypes in the male subjects of this study are not those targeted by the HPV vaccines available in our countries. Hence the need to reinforce the strategies for controlling HPV infection and HPV prophylactic vaccination for young boys.

Abstract Background Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. Methods In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. Results The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p<0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16–24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p<0.05). Conclusions HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

ABSTRACT The host’s immune response to cervical human papillomavirus (HPV) infection is poorly understood. In a longitudinal cohort of women with cervical HPV infections, defined by PCR-based HPV DNA testing, we used exfoliated cervical cells and reverse transcription-PCR to examine the cervical mucosal mRNA expression of cytokines involved in regulating cell-mediated immunity. We identified seven HPV-positive subjects who were found to have cleared their HPV infections 4 months later. In all seven, a T-helper type 1 (Th1) cytokine pattern (expression of gamma interferon and absence of interleukin-4) preceded clearance. The more variable cytokine patterns seen in HPV-negative subjects suggest that the Th1 pattern in the women with subsequent clearance was a response to the HPV infection. This contention is supported by additional cross-sectional data showing a Th1 pattern in a majority of HPV-positive women. This study establishes a feasible means for assessing local cytokine expression in the cervical milieu and demonstrates that a Th1 cytokine response is associated with subsequent clearance of cervical HPV infection.

Background: The role of human papillomavirus (HPV) as single or multiple infections in pregnant women would be relevant to determining the time to progression and/or the time to regression of cervical lesions. Objective: In this preliminary study, we determined the prevalence of HPV as single or multiple infections in pregnant women from Northeastern Mexico. Materials and Methods: Samples from 31 pregnant and 62 nonpregnant women were examined between January 2015 and November 2015 at UMAE-23 of the Instituto Mexicano del Seguro Social (IMSS). The samples of cervicovaginal exudate were obtained for HPV DNA detection using the INNO-LiPA test, and HPV infections were analyzed as single or multiple infections. Participants completed a questionnaire on sociodemographic, gynecological, obstetric, and sexual behavior characteristics. Results: The mean age of the pregnant women was 25.7 ± 4.8 yr, with an average time of pregnancy of 6 ± 1 months at the time of the study. With respect to age, parity, smoking history, or oral contraceptive use no statistically significant differences between the two studied groups was observed. The HPV infection was 2.7 times higher in pregnant women (35%) than in the control group (13%). In total, 78% of the pregnant women who were HPV-positive presented with single infections compared with 28% of the nonpregnant women. Conclusion: A higher prevalence of HPV as a single infection was found in this sample of pregnant Mexican women. Follow-up is necessary to evaluate the persistence or regression of the infection.

Abstract Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases. To define the HPV-associated microbial community among a high vaccination coverage population, we carried out a cross-sectional study with 345 young Swedish women. The microbial composition and its association with HPV infection, including 27 HPV types, were analyzed. Microbial alpha-diversity was found significantly higher in the HPV-infected group (especially with oncogenic HPV types and multiple HPV types), compared with the HPV negative group. The vaginal microbiota among HPV-infected women was characterized by a larger number of bacterial vaginosis-associated bacteria (BVAB), Sneathia, Prevotella, and Megasphaera. In addition, the correlation analysis demonstrated that twice as many women with non-Lactobacillus-dominant vaginal microbiota were infected with oncogenic HPV types, compared with L. crispatus-dominated vaginal microbiota. The data suggest that HPV infection, especially oncogenic HPV types, is strongly associated with a non-Lactobacillus-dominant vaginal microbiota, regardless of age and vaccination status.

Objective Oral human papillomavirus (HPV) infection is the precursor for a growing subset of oropharyngeal squamous cell carcinomas (OPSCCs) in the developed world. This study was designed to characterize oral HPV infection and OPSCC in a region with high rates of HPV-driven cervical cancer. Study Design Cross-sectional cohort study, retrospective case series. Setting Northwest Cameroon referral hospital. Subjects and Methods Individuals infected with human immunodeficiency virus attending an outpatient clinic were evaluated for oral HPV infection with oral swabs or rinses that were tested for 51 HPV types. HNSCCs diagnosed and/or treated at the same hospital from 2011 to 2017 were retrospectively reviewed to ascertain demographic and tumor characteristics, and available OPSCCs were tested for HPV. Results The oral HPV infection study population comprised 101 participants. Most (69%) were female and never-smokers (84%). Participants had median 4 lifetime sexual partners (interquartile range, 3-7; range, 1-100). Five participants (5%) had oral HPV infection; one had 2 HPV types. HPV types detected were HPV68 (n = 2), HPV82 (n = 2), HPV32 (n = 1), and unknown (n = 1). No significant demographic or behavioral differences were detected among individuals with vs without oral HPV infection. OPSCCs comprised just 8% (n = 11) of 131 HNSCCs in the retrospective study population. Two of 7 OPSCCs were HPV positive. Conclusion The low prevalence of OPSCC observed in northwest Cameroon together with the rarity of oral HPV infection suggests low rates of HPV-driven oropharyngeal carcinogenesis in the region. Future research should examine how geographic differences in oral HPV infection are influenced by cultural norms and affect HPV-OPSCC epidemiology.

Cervical Infection

Human papillomavirus cervical infection was investigated in a series of 300 unselected women by comparing morphological diagnoses (cytology and histology) with results of DNA hybridization techniques (filter in situ hybridization of DNA from exfoliated cervical cells and Southern blot analysis of HPV-DNA in cervical biopsy specimens). The prevalence of HPV cervical infection diagnosed by PAP smears was 11.6 %. Despite disadvantages, filter in situ hybridization was confirmed to be particularly useful for screening purposes to detect HPV in cervical scrapings. In 3 cases it was the only applicable method for diagnosing « high-risk » HPV infection. Southern blot hybridization of tissue DNA with HPV 16-DNA revealed the presence of this virus in 8 cases, and HPV 31-DNA and HPV 42-DNA in 1 case each.
