The study purpose was to investigate the association of human papillomavirus (HPV) infection with prostate cancer. The presence and type of HPV DNA were investigated by polymerase chain reaction in the preservation fluid of 60 consecutive prostate core biopsies (29 benign, 31 malignant). The material was inadequate (no DNA found at β-globin testing) in four benign and five cancer biopsies. HPV DNA was found in 17 of 26 (65.3%) cancer and 12 of 25 (48.0%) benign biopsies (χ2 = 0.94, p = 0.33). High-risk HPV type positivity was observed in 14 of 26 (53.8%) cancer and in five of 25 (20.0%) benign biopsies (χ2 = 4.38, p = 0.03). Twenty-three of 29 cases were positive at L1 region testing with MY09/11 primers; testing with primers directed to the E6/E7 region revealed six further HPV-positive cases (four cancer, two benign). The presence of HPV in prostate tissue suggests a possible reservoir for sexual transmission of types with oncogenic potential. Our findings also suggest a possible role of high-risk HPV infection in the etiology of prostate cancer and encourage further research into this issue.

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.

The Impact

Abstract Study question Is there any correlation between men infertility and HPV infection and its impairment on sperm quality? Summary answer There is a significantly higher prevalence of high-risk HPV in infertile men than fertile men. HPV infection does not impair sperm quality. What is known already Many factors may cause the infertility in males and females. Human papillomavirus are the most frequently sexually transmitted DNA viruses and etiological agents of cervical cancers. There is association between HPV infection in females and adverse pregnancy outcomes such as spontaneous abortion and spontaneous preterm delivery. Previous studies have reported the detection of HPV DNA in semen and in different sites of the male reproductive tract, such as glans penis and scrotum. Recent reports suggested that HPV may affect sperm parameters and lead to male infertility. The impact of HPV infection upon male fertility abnormality has received far less attention. Study design, size, duration In this study case control study we examined 38 fertile and 36 men from infertle couples. Participants/materials, setting, methods we examined the swabs of the entire penile surface and semen samples for HPV detection and genotyping from 38 fertile men and 36 from men from infertile couples.HPV were detected with PCR method. Sperm was also examined for its motility, sperm quantity and morphology . Main results and the role of chance Among 36 confirmed infertile males, only 8 (22.22%) cases were tested positive for HPV of semen samples and 2 among fertile men were HPV-positive (5.26%) of semen samples. Among infertile males 14 (38.88%) had HPV positive penile swabs, and only 1 (2,63%) had positive HPV swab among fertile men. The most prevalent HPV types in the male external genitalia were HPV–16. The most prevalent HPV types in semen were HPV–53. This data revealed a significant association between high-risk HPV and male infertility (P = 0.03). Sperm quality (morphology and motility) did not differ significantly between men with seminal HPV infection and uninfected men. Limitations, reasons for caution There were some limitations in the study such as differences in age. sample sizes and the number of HPV genotypes detected. Wider implications of the findings: We need larger studies and more further investigations to confirm the impact of HPV on male infertility. Trial registration number 2

High Risk Hpv

Recent decades have witnessed a reduction in the incidence of cervical cancer in countries where screening programmes have achieved broad coverage. The recognized importance of high-risk HPV (human papillomavirus) infection in the aetiology of cervical cancer may introduce a role for HPV DNA testing in cervical screening programmes. Positive HPV DNA tests indicate women at risk of cervical cancer with greater sensitivity, but reduced specificity, compared with exfoliative cytology. Combining HPV testing with cytology may be useful in the triage of minor cytological abnormalities into those requiring referral to colposcopy (HPV positive) compared with those who can be safely managed by cytological surveillance (HPV negative). With its high sensitivity and high-negative-predictive value, HPV testing may also be useful for predicting treatment failure, since residual disease is very unlikely in the event of a negative HPV test. Ultimately, prevention is better than cure, and the advent of HPV prophylactic vaccines may obviate the need for population-based cervical screening programmes in the future. A multivalent vaccine administered to adolescents prior to the onset of sexual activity and boosted at regular intervals throughout their sexually active life may provide protection against type-specific HPV infection, malignant precursors and invasive cervical disease. Several large randomized placebo-controlled trials have been conducted with promising results. For those generations of women already exposed to high-risk HPV infection, therapeutic vaccines may offer advantages over conventional treatment, although much work still needs to be done.

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.

Background. Cardiovascular diseases are leading causes of death worldwide. Recent studies suggest that infection by some viruses, including the human papillomavirus (HPV), may increase the risk of developing atheromatous lesions on coronary arteries. However, there is a lack of data regarding the possible association between HPV infection and coronary artery disease (CAD) in women. Objective. To investigate whether HPV infection is associated with the occurrence of CAD among climacteric women. Methods. The presence of CAD and cervical HPV DNA was investigated in 52 climacteric women. Social and demographic variables and metabolic profiles were also investigated. Results. Among 27 women with CAD, 16 were positive for HPV, whereas 11 were negative. The presence of cervical HPV was strongly associated with CAD, after adjusting for demographic variables, health and sexual behaviors, comorbidities, and known cardiovascular risk factors. HPV-positive women showed a greater likelihood of having CAD (odds ratio [OR] = 3.74; 95% confidence interval [CI]: 1.16 to 11.96) as compared with HPV-negative women, particularly those infected with high-risk HPV types (OR = 4.90; 95% CI: 1.26 to 19.08). Conclusion. These results support the hypothesis that HPV infection might be associated with CAD among climacteric women, though further studies are needed to investigate the mechanisms involved.

Objective. Animal data suggest that cocaine has an immunosuppressive effect, but no human studies have been conducted to assess the relation of cocaine use with human papillomavirus (HPV) infection, the viral cause of cervical cancer. Since both cocaine use and HPV infection are common among HIV-positive women, we sought to determine whether use of cocaine and/or crack influences the natural history of HPV among women with or at high risk of HIV.Methods. Women enrolled in the Women's Interagency HIV Study (2278 HIV-seropositive and 826 high-risk seronegative women) were examined every six months for up to 9.5 years with Pap smear, collection of cervicovaginal lavage (CVL) samples, and detailed questionnaires regarding health and behavior, including use of crack and cocaine (crack/cocaine). CVLs were tested for HPV DNA by PCR, with genotyping for over forty HPV types.Results. In multivariate logistic regression models, censoring women treated for cervical neoplasia, crack/cocaine use within the last six months was associated with prevalent detection of oncogenic HPV DNA (odds ratio [OR] = 1.30 (1.09–1.55)), and with oncogenic HPV-positive squamous intraepithelial lesions (SIL) (OR = 1.70 (1.27–2.27)), following adjustment for age, race, HIV-serostatus, and CD4+ T-cell count, the number of sexual partners in the past six months, and smoking. In multivariate Cox models crack/cocaine use was also associated with a trend that approached significance in regard to incident detection of oncogenic HPV-positive SIL (HR = 1.51, 95% CI 0.99–2.30), and while the rate of oncogenic HPV clearance was not related to cocaine use, the clearance of any SIL was significantly lower in those with versus those without recent crack/cocaine use (HR = 0.57, 95% CI 0.34–0.97).Conclusions. Cocaine use is associated with an increased risk of detection of both prevalent and incident oncogenic HPV infection, as well as an increased risk of HPV-positive SIL over time.

ObjectivesPersistent infection with specific genotypes of human papillomaviruses (HPVs) is the main cause of invasive cervical cancer (ICC). Only a few of the various HPV types account for most of the cases worldwide, and geographical differences in their distribution are evident. Data from locally prevalent genotypes are essential in view of introduction of HPV type-specific prophylactic vaccines.MethodsIn this work, we have investigated HPV type distribution in samples of ICC cases that occurred in Uruguayan women. DNA extracted from ICC treated in Centro Hospitalario Pereira Rossell of Montevideo between 1999 and 2007 were analyzed. Search and typing were performed by polymerase chain reaction using generic GP5+/GP6+ primers and specific primers for HPV types 16, 18, 33, and 45. Positive GP5+/GP6+ samples, which were negative for all 4 high-risk HPV-specific types screened were further analyzed by sequencing.ResultsHuman papillomavirus DNA sequences were found in 163 (92.6%) of 176 cases. The most prevalent genotypes were HPV16 (67.6%) and HPV18 (8.5%) followed by HPV45 (6.8%) and HPV33 (3.4%), as single or mixed infection. Other less frequent genotypes were HPV31, HPV35, HPV39, HPV51, HPV52, HPV58, HPV66, and HPV73. The viral type could not be determined (HPV X) in 1 case (0.6%) of the HPV DNA–positive cervical cancers and double infections were found in 1.7% of the cases. The higher percentage of most aggressive HPV (16/18/45) genotypes was detected in cases diagnosed at younger than 60 years old, whereas these genotypes were less frequent in older patients.ConclusionWe conclude that HPV types 16, 18, and 45 have a very high prevalence in ICC of Uruguayan women. Results provide evidence that 16 of 18 infections are more aggressive, but most cancers could be vaccine preventable.
