Human papillomavirus (HPV)–related carcinoma with adenoid cystic–like features is a rare, recently recognized entity restricted to the sinonasal tract. By definition, it is associated with high-risk HPV infection, particularly with HPV type 33. In most cases, tumors are composed of dual cell populations, including predominant basaloid myoepithelial cells and usually inconspicuous ductal cells. Solid components with focal cribriform or tubular patterns, abrupt keratinization within tumor nests, and squamous dysplasia of the surface epithelium are characteristics of HPV-related carcinoma with adenoid cystic–like features. The immunohistochemistry of p16 followed by high-risk HPV testing may help in the differential diagnosis. Recent studies have demonstrated that the morphologic features of this entity are more diverse than initially believed. Surgical resection is the prime alternative for treatment. According to the limited data, the prognosis of this disease may be better than that of other sinonasal carcinomas.

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.

Abstract In this study, a total of 301,880 woman were recruited from 4 different regions of China. The overall prevalence of HPV was 18.01 %. The high-risk HPV infection rate was 79.14%, the low-risk HPV infection rate was 12.56 %, and the mixed HPV infection rate was 8.30%. The most common 4 HR HPV subtypes were HPV-52, 16, 58 and 53, which accounted for 20.49 %, 19.93 %, 14.54 % and 10.01 %. In LR HPV genotype, HPV-6 ranked the highest (28.17 %), followed by HPV-81 (9.09 %) and HPV-11 (3.78 %). HPV genotype subgroup analysis also showed that single-type infections had the highest prevalence rate (77.26 %) among HPV positive individuals. Among muti-infection genotype, double infection was the most common with frequencies of 76.04 %. This large report showed that the overall prevalence of HPV was high in China, whose distribution exhibits different patterns across different particular age and regions. Viral genotypes HPV 53, 6 were frequently detected in this population, which is worth of significant clinical attention.

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.

Hpv Viral Load

Human papillomavirus (HPV) high risk genotype infection and HPV viral load influences the development of invasive cervical cancer and cervical intra-epithelial neoplasia (CIN). HPV DNA testing for screening of cervical cancers may play a potential role in its early detection and management. The present study detected HPV DNA and estimated HPV viral load in different types of cervical lesions among Bangladeshi women. Using the Hybrid Capture 2 (HC2) assay, HPV DNA was tested among 68 women between 25-70 years of age. A total of 13 (19.1%) cases were positive for HPV DNA. The highest viral load (501 x 10³ copies/ml) was detected in a patient with invasive carcinoma, while the lowest viral load (105 x 10³ copies/ml) was detected from a case of chronic cervicitis. The mean viral load in CIN I was 119.25 x 10³±12.5 x 10³ copies/ml (range: 110 x 10³ - 137 x 10³) and 208.50 x 10³ ± 0.59 x 10³ copies/ml (range: 139 x 10³-305 x 10³) in CIN II / III. Interestingly, HPV DNA was detected from a patient with normal cytological findings. Our study observed a moderate presence of high-risk HPV genotypes among women with cervical lesions. The HPV viral load varied with the age of the patients and stage of cervical lesions. The HC2 assay is a promising tool for diagnosing high-risk HPV infection especially before cytology tests show any abnormality.

Abstract Background The incidence rate of cervical cancer is increasing yearly. The persistent infection of high-risk human papillomavirus (HPV) is the main factor leading to cervical cancer. HPV infection is double peak type. This study aimed at analyzing the HPV distribution characteristics, infection rate, and risk of age in pre- and postmenopausal women. So as to provide reference for the prevention of HPV infection and cervical cancer screening strategy. Methods A retrospective analysis of 4614 women who underwent cervical cytology, and HPV examination from January 2018 to October 2019 at the healthcare department of Wuhan Union Hospital was done. We explored the characteristics and distribution of HPV infections around the menopause, then comparing the infection rate of HPV in postmenopause and over 65 years old, in order to analyze the influence of different ages on HPV infection. Results Generally, the HPV infection rate was 13.10% (539/4115), whereby the high-risk subtype constituted 73.84% (398/539) of all positive cases. On the other hand, the HPV39 infection was more common in postmenopausal women; however, there was no significant difference in the distribution of the other types in the pre- and postmenopausal women. The first four types were 52/53/58/16. The results further showed that the rates of HPV infection before and after menopause were 12.34% (367/2975) and 15.09% (172/1140), respectively, which had no significant difference (P = 0.056), but more susceptible to high-risk HPV infection after the age of 65 (P = 0.041). Except for 40 years old to menopause, the infection rate of high-risk HPV in this age group was different from that in postmenopause (P = 0.023, 0.729 (0.555, 0.957)), other age groups had no significant effect on high-risk HPV infection. Conclusions It was concluded that whether menopause has nothing to do with HPV infection. Moreover, the risk of high-risk HPV infection in women aged 40 to premenopausal is relatively low, but the infection rate increases after 65. Hence the cutoff screening age should be appropriately prolonged.

Abstract Background Human papillomavirus (HPV) causes oral warts and oropharyngeal cancer (OPC). Human papillomavirus-attributable OPC incidence among men is significantly increasing worldwide, yet few studies have reported oral HPV across multiple countries or examined factors associated with low- and high-risk HPV separately. Methods Oral gargles from 3095 men in the multinational HPV Infection in Men (HIM) Study were HPV genotyped. Multivariable models assessed factors independently associated with high-risk and low-risk HPV prevalence. Results The prevalence of high-risk and low-risk HPV was 6.0% and 2.8%, respectively. Greater number of sexual partners was only associated with high-risk HPV (1.88; 95% confidence interval [CI], 1.22–2.90) prevalence. In multivariable models, residing in Mexico (1.66; 95% CI, 1.15–2.40) and smoking (1.66; 95% CI, 1.13–2.44) were significantly associated with high-risk HPV, and history of consistent gum bleeding (2.16; 95% CI, 1.35–3.45) was significantly associated with low-risk HPV. Gender of the sexual partner did not alter the results for either high- or low-risk HPV endpoints. Conclusions Different factors were independently associated with high- and low-risk oral HPV. Oral sexual behaviors were associated with high-risk HPV, and oral health was associated with low-risk HPV. High-risk HPV prevalence differed by country of residence, highlighting the need for additional studies in multiple countries.

Human papillomavirus (HPV) infection is thought to be strongly associated with the precarcinomatous state cervical intraepithelial neoplasia (CIN) and cervical carcinoma. To accurately assess the correlation between HPV detection profiles and CIN, the uniplex E6/E7 polymerase chain reaction (PCR) method was used. We detected HPV (37 genotypes) in 267 CIN cases. The detection of a single high-risk HPV genotype occurred in 69.7% of CIN1 and worse than CIN1 (CIN1+) cases whereas other types were detected in 11.6% of cases. Codetection of high-risk HPV genotypes occurred in 4.9% of CIN1+ cases. The high-risk genotype HPV16 was the most frequently detected genotype in CIN1+ lesions; the genotype HPV34 (not a high-risk type) was detected in some CIN3 cases. Furthermore, HPV codetection may not be associated with CIN grades. These results suggest that various HPV genotypes are associated with CIN across all analyzed cases.

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), originally known as HPV-related carcinoma with adenoid cystic carcinoma-like features, is a recently described neoplasm that presents only in the sinonasal tract, displays features of both a surface-derived carcinoma and a salivary gland carcinoma, and is associated with high-risk HPV, specifically HPV type 33. Majority of the cases display high-grade histologic features, but HMSC paradoxically behaves in a relatively indolent fashion. Distinguishing HMSC from other histologic mimickers is essential as the management and prognosis are significantly different. In this article, we present a unique case of HMSC and review the literature.

Abstract Background High-risk anal human papillomavirus (HPV) infection is prevalent among men living with human immunodeficiency virus (HIV); the association between 9-valent (9v) high-risk HPV (HR-HPV) vaccine types and abnormal cytology has not been well characterized. Methods We followed a prospective cohort study of persons with HIV at 7 HIV clinics in 4 US cities from March 2004 through June 2012. Annually, providers collected separate anal swabs for HPV detection and cytopathologic examination. Among men, we examined prevalence, incidence, and clearance of 9v HR-HPV vaccine types, compared with other HR types, and associations with abnormal cytology to assess potential vaccine impact. Results Baseline prevalence of any anal 9v HR-HPV type among men who have sex with men (MSM) and men who have sex with women (MSW) was 74% and 25% (P < .001), respectively. Among 299 MSM, abnormal cytology was detected in 161 (54%) MSM and was associated with the presence of any 9v HR-HPV (relative risk [RR], 1.8 [95% confidence interval {CI}, 1.3–2.6]; P < .001). Among 61 MSW, abnormal anal cytology was detected in 12 (20%) and was associated with the presence of any 9v HR-HPV (RR, 4.3 [95% CI, 1.6–11.5]; P < .001). Conclusions Among men with HIV, the prevalence of the 7 HR-HPV types in the 9v vaccine was high and was associated with abnormal cytology. These findings indicate that men with HIV could benefit from prophylactic administration of the 9v HPV vaccine.
