RESULTS:. The 42 selected articles enrolled 4066 patients. It was observed that oral or oropharyngeal human papillomavirus infections were identified in 738 patients (18.2%; IC 95 17.6-18.8), varying between 0.0% and 91.9%. The prevalences of oral or oropharyngeal human papillomavirus infections were respectively 6.2%, 44.6%, 44.4%, 27.4%, 38.5% and 11.9% for healthy people, those with benign oral lesions, pre-malignant lesions, oral or oropharyngeal squamous cell carcinoma, risk groups (patients with genital human papillomavirus lesions or infected partners) and immunocompromised patients. The risk of human papillomavirus infection was estimated for each subgroup and it was evident that, when compared to the healthy population, the risk of human papillomavirus infection was approximately 1.5-9.0 times higher, especially in patients with an immunodeficiency, oral lesions and squamous cell carcinoma. The rates of the most well-known oncogenic types (human papillomavirus 16 and/or 18) also show ...
Distribution of Human Papilloma Virus Infections of Uterine Cervix among Women of Reproductive Age - a Cross Sectional Hospital-Based Study from North East India Human papilloma virus;cervical cancer;squamous epithelial lesion;PCR;NILM;India; Infection of the uterine cervix by human papilloma viruses (HPV) may be associated with cervical pre-cancer and invasive cervical carcinoma if left untreated. With advance in molecular techniques, it has become easier to detect the resence of HPV DNA long before the appearance of any lesion. This study concerned cervical scrape samples of 310 married non-pregnant women attending a gynecology outpatient department for both Pap and PCR testing to detect HPV DNA. Nested PCR using primers for L1 consensus gene with My9/My11 and GP6+/GP5+followed by multiplex PCR were carried out to detect HPV 16 and HPV18. Result: HPV prevalence was 11.9% out of which 3.67% cases of negative for intra-epithelial lesion or malignancy (NILM) and in 71.1% (27/38) of atypical cervical
Human papillomavirus infection is an infection by human papillomavirus (HPV). Most HPV infections cause no symptoms and resolve spontaneously. In some people, an HPV infection persists and results in warts or precancerous lesions. The precancerous lesions increase the risk of cancer of the cervix, vulva, vagina, penis, anus, mouth, or throat. Nearly all cervical cancer is due to HPV with two types, HPV16 and HPV18, accounting for 70% of cases. Between 60% and 90% of the other cancers are also linked to HPV. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis. An HPV infection is caused by human papillomavirus, a DNA virus from the papillomavirus family, of which over 170 types are known. More than 40 types are transmitted through sexual contact and infect the anus and genitals. Risk factors for persistent HPV infections include early age of first sexual intercourse, multiple partners, smoking, and poor immune function. HPV is typically spread by sustained direct ...

N2 - Background: Cervical cancer, caused by persistent infection with carcinogenic human papillomavirus (HR-HPV), is particularly prevalent in Sub-Saharan Africa and is associated with a high mortality rate. Some studies in West Africa, including our own, have found unusually high HR-HPV across all ages with a slight peak in older women. This increased prevalence at older ages may complicate screen-and-treat programs, which are implemented in regions where HPV prevalence declines with age and typically target women between 30-49 years. A better understanding of the determinants of high HR-HPV prevalence at older ages is ...

In the literature, data on the prevalence of human papillomavirus (HPV) infection in men vary significantly and the exact distribution of specific genotypes is still unclear. As infections usually occur without symptoms, men might only attend their hospital clinic when they have a specific concern, being in most cases genital warts (condylomas), which are often caused by low-risk HPV genotypes. The aim of this study was to assess HPV genotype distribution and prevalence among men attending hospital for HPV-associated conditions and to evaluate infection-associated factors. Samples from men with clinical manifestations of HPV-related infections seen during 2007-2012 at the Clinical Microbiology and Infectious Control Department at Basurto University Hospital were genotyped using Linear Array HPV Genotyping Test kit (Roche Molecular Diagnostics, Germany). Data on probable risk factors were collected and investigated for possible association. Of 184 anogenital samples, 138 (75 %) were tested as positive
Research presented at the 2017 American Society of Clinical Oncology showed that although human papillomavirus (HPV) vaccine reduces the rate of oral HPV infection, the vaccine is still underutilized among teens and young adults.. -----.

Discussion. Genital HPV infection is the most common sexually transmitted disease. Taking into consideration of all the cervical cancer cases, 99,8% of the patients were infected by HPV. HPV infection may cause either genital wart, precancerous cervical lesions or cervical cancer. While more than 100 HPV subtypes exist, 30 subtypes may lead to infection in human. According to the oncogenicity potential, HPV types are classified as high risk (HR; type 16, 18, 31, 45, 51, 52, 59, 68) and low risk (LR; type 6 and 11) (1-4).. HPV infection prevalence exhibits regional variations. The incidence of HPV among 14-59 years of age Americans is 26,8% and the most common HPV subtype is type 6 (1,3%) (14), while this incidence is 17% in Spaniens and the most common HPV subtype is type 16 and 18 (15). On the other hand, among Indian women, type 16 is the most common HPV subtype and the incidence is 7,6% (16), in Denmark the percentage of the HPV infected women is 26,4 % type 16 is the most common one (6,0%) ...

In a study in Malawi, HIV-infected women were three times more likely than uninfected women to have persistent human papillomavirus infections (HPV), and twice as likely to have cervical abnormalities, according to NIAID-supported investigators and their colleagues. HPV infection is causally associated with cervical cancer, the most common malignancy among women in the developing world. Scientists estimate that worldwide 500,000 new cases of cervical cancer and 300,000 related deaths occur annually.. As reported in the March 1996 Journal of Infectious Diseases, the researchers found squamous epithelial lesions in 15 percent of 116 HIV-positive women, and 7 percent of 152 HIV-negative women. This heightened occurrence of cervical lesions probably resulted from a greater overall frequency of HPV infections (48 percent vs. 23 percent) in the HIV-positive group, write Paolo G. Miotti, M.D., of NIAIDs Division of AIDS, Keerti V. Shah, M.D., of The Johns Hopkins University School of Hygiene and ...
According to the National Cancer Institute, "The most common test[which?] detects DNA from several high-risk HPV types, but it cannot identify the type(s) that are present. Another test[which?] is specific for DNA from HPV types 16 and 18, the two types that cause most HPV-associated cancers. A third test[which?] can detect DNA from several high-risk HPV types and can indicate whether HPV-16 or HPV-18 is present. A fourth test[which?] detects RNA from the most common high-risk HPV types. These tests can detect HPV infections before cell abnormalities are evident.. "Theoretically, the HPV DNA and RNA tests could be used to identify HPV infections in cells taken from any part of the body. However, the tests are approved by the FDA for only two indications: for follow-up testing of women who seem to have abnormal Pap test results and for cervical cancer screening in combination with a Pap test among women over age 30."

This is the first study from Curaçao to show systematic data on HPV prevalence in cervical cancer and CIN lesions. Interestingly, although the prevalences of HPV16 (38.5%) and HPV18 (13.5%) in cervical cancer of women from Curaçao are still the most prevalent HPV genotypes, their prevalence is lower compared with the world prevalence.19-21. The prevalence of vaccine types HPV31, HPV52, HPV58 and HPV X (DEIA pos. and LiPA neg.) for each HPV type was 3.8%, in total 15.2%. In ADC (n=15), HPV 18 (40.0%), HPV16 (26.7%) and HPV45 (13.3%) were the most prevalent HPV types. Twelve cervical cancers were found to be HPV negative.. We performed several experiments to substantiate absence of HPV in cervical cancer and exclude experimental causes. Review of the slides by two pathologists did not change the diagnosis, and repeated HPV testing and genotyping with SPF10 yielded identical results. Inadequate DNA quality could be excluded by parallel testing with a duplex real-time PCR targeting the human ...
Screening with cervical cytology and/or testing for multiple oncogenic HPV types can lead to the detection of high-grade precancerous cervical lesions and cervical cancer. High-risk HPV genotypes are necessary for the development of cervical cancer. HPV types 16 and 18 are the most carcinogenic genotypes, accounting for 55-60% and 10-15% of all cervical cancers, respectively. Low-risk HPV types are unrelated to cervical cancer and have no clinical role in cervical cancer screening or the evaluation of women with abnormal cytology.. Conventional or liquid-based cytology, with or without reflex to hrHPV testing, is the recommended screening method in women 21-29 years of age and should be performed every 3 years. Cotesting is defined as screening by cytology and HPV testing, and is the preferred screening method in women 30 years and older. This method is more sensitive than cytology alone at detecting cervical abnormalities and has the potential to enable both increased disease detection and ...

Background: Cervical cancer (CC) is the fourth most commonly diagnosed cancer among women. Ghana is a low-middle- income country with annual diagnosed cases of 3,151 and 2,119 deaths. The high prevalence rate of cervical cancer in Ghana is mainly due to ineffective preventive measures and insufficient knowledge about the disease. Therefore, our objective was to evaluate the level of knowledge and awareness of cervical cancer and attitude toward human papillomavirus and its vaccine among Ghanaians.Methods: This descriptive cross-sectional survey on the awareness of cervical cancer and attitude toward human papillomavirus and its vaccine was carried out from March 2019 to February 2020. SPSS v. 23.0 was used in the data analysis. The participants demographic characteristics, knowledge of cervical carcinoma, human papillomavirus vaccine and HPV, and the likelihood to be vaccinated were represented as percentages and frequencies. The difference between males and females was assessed using the chi-square
Background: We assessed the association of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) with various characteristics, CD4 count and use of combination antiretroviral therapy (cART) among HIV-positive women. Methods: Cross-sectional study of 498 HIV-positive women who underwent HPV PCR-based testing, cytology, and systematic cervical biopsy. Results: In all, 68.7% of women were HPV-positive, 52.6% had high-risk (hr) HPV, and 40.2% multiple type infections. High-risk human papillomavirus-positivity did not vary significantly by age but it was negatively associated with education level. The most frequent types in 113 CIN2/3 were HPV16 (26.5%), HPV35 (19.5%), and HPV58 (12.4%). CD4 count was negatively associated with prevalence of hrHPV (Po0.001) and CIN2/3 among non-users of cART (P¼0.013). Combination antiretroviral therapies users (X2 year) had lower hrHPV prevalence (prevalence ratio (PR) vs non-users¼0.77, 95% confidence interval (CI): 0.61-0.96) and multiple
The current study extended a previous investigation on the obesity-HPV association from a specific age group (aged 35-60) [12] to adult women in general (aged 20-59). Overall, we found a null or weak association between obesity or central obesity and HPV infection in this nationally-representative adult female population. However, subgroup analysis showed that obese or centrally-obese women had a significantly reduced HR-HPV infection among those who reported an early sex debut (,16 years) or those included in the fasting subpopulation. We proposed three potential mechanisms for these observed negative correlations.. First, despite the early sex debut, adult women with excessive adiposity might have a lower HPV burden than women with normal BMI or WC. Early studies on adolescents have consistently linked early sex debut to an increased risk for sexually transmitted infections (STI), including HPV infection [30, 31]. The heightened STI risks were reportedly mediated by concomitant risky behaviors ...
A groundbreaking study published in the Asian Pacific Journal of Cancer Prevention, titled, "Clearance of Cervical Human Papillomavirus Infection by Topical Application of Curcumin and Curcumin Containing Polyherbal Cream: A Phase II Randomized Controlled Study," reveals that vaccination and watchful waiting are not the only recourse against HPV infection.. The study is believed to be the first of its kind to find an effective and safe therapeutic intervention for the clearance of established cervical human papillomavirus (HPV) infection. Moreover, the study confirmed that HPV infection is self-limiting and clears on its own in 73.3% of the untreated placebo group within 37 days.. The researchers evaluated the effectiveness of two herbal interventions in eliminating HPV infection from the cervix of women who were determined to have HPV infection through Pap smear and HPV DNA tests (PCR), but whose condition had not yet progressed to high grade cervical neoplasias (i.e. cervical ...
Cervical cancer is by far the most common HPV-related disease. About 99.7% of cervical cancer are caused by persistent genital high-risk human papillomavirus (HPV) infection. Worldwide, cervical cancer is one of the most common cancer in women with an estimated 528,000 new cases reported in 2012. Most HPV infections clear spontaneously but persistent infection with the oncogenic or high-risk types may cause cancer of the oropharynx and anogenital regions. The virus usually infects the mucocutaneous epithelium and produces viral particles in matured epithelial cells and then causes a disruption in normal cell-cycle control and the promotion of uncontrolled cell division leading to the accumulation of genetic damage. There are currently two effective prophylactic vaccines against HPV infection in many developed countries and these comprise of HPV types 16 and 18, and HPV types 6, 11, 16 and 18 virus-like particles. HPV testing in the secondary prevention of cervical cancer is clinically valuable in
The establishment of Human Papillomavirus HPV infection as a necessary risk factor for about 95% of cervical cancers has over the past few years raised the question of how this knowledge should best be used for optimization of cervical cancer screening programs. Key features of the epidemiology of HPV infection are now known. The incidence and...

Signs of Human Papillomavirus including medical signs and symptoms of Human Papillomavirus, symptoms, misdiagnosis, tests, common medical issues, duration, and the correct diagnosis for Human Papillomavirus signs or Human Papillomavirus symptoms.
Lien vers Pubmed [PMID] - 24332295. Vaccine 2013 Dec;31 Suppl 7:H1-31. Infection with human papillomavirus (HPV) is recognized as one of the major causes of infection-related cancer worldwide, as well as the causal factor in other diseases. Strong evidence for a causal etiology with HPV has been stated by the International Agency for Research on Cancer for cancers of the cervix uteri, penis, vulva, vagina, anus and oropharynx (including base of the tongue and tonsils). Of the estimated 12.7 million new cancers occurring in 2008 worldwide, 4.8% were attributable to HPV infection, with substantially higher incidence and mortality rates seen in developing versus developed countries. In recent years, we have gained tremendous knowledge about HPVs and their interactions with host cells, tissues and the immune system; have validated and implemented strategies for safe and efficacious prophylactic vaccination against HPV infections; have developed increasingly sensitive and specific molecular ...
The systematic review by Rambout et al is a high-quality synthesis of the evidence to date on the effectiveness of prophylactic HPV vaccination in preventing persistent HPV infection and precancerous cervical changes in young women. Infection with HPV is common;1 however, current primary prevention strategies, such as condom use, can only reduce the risk of transmission.2 The vaccines included in this review provide highly effective protection against 2 high-risk HPV types (16 and 18), which account for 70% of all cervical cancers. 1 of the vaccines tested provides additional coverage against non-oncogenic HPV types 6 and 11, which have been associated with the development of external genital disease.. Questions remain about the long-term effectiveness of the vaccine in reducing cervical cancer incidence and mortality, effectiveness of the vaccine in real world populations, duration of effect, and the optimal age to immunise young women if the vaccine is publicly funded. Despite these gaps in ...
The prevalence of oral HPV infection among men in the HITCH cohort was 7.2%. To our knowledge, this is the first study to demonstrate higher oral HPV prevalence among men whose female partner had a prevalent genital or oral HPV infection suggesting that transmission may occur through oral or genital routes. Prevalence was also significantly higher among men who had ever smoked, had a high number of lifetime sex partners, or were in nonmonogamous relationships. Our results are largely consistent with previous studies that have found male sex, smoking, and sexual behaviors to be the most significant risk factors for oral HPV infection (2-4, 6, 7, 11).. We found that overall prevalence of oral HPV infection was higher among ever smokers. Others have found that current smoking increases the risk for both prevalent and incident HPV infection (2, 4, 7). Among men in the HPV Infection in Men (HIM) cohort study, the odds of a prevalent infection were increased among current smokers as was the risk of ...
Human papillomavirus (HPV) is a frequently occurring viral infection that is sexually transmitted. HPV infections often present with mild symptoms or are asymptomatic and do not always progress to a disease state. However, some HPV infections can cause cervical or other anogenital carcinomas. If HPV screening is done regularly, most cervical cancers can be prevented. In fact, cervical cancer is one of the most successfully treated cancers. Management of HPV has changed dramatically with the introduction of DNA methods for diagnosis of HPV infections, and vaccines for the prevention of HPV infections. This course is intended to increase your knowledge about HPV and to acquaint you with molecular methods that are currently available for detection of HPV DNA in cervical cells..

Preanalytical conditions determine the reliability and validity of bioassays. Therefore, the analytic performances of biological tests need to be determined when preanalytical steps differ from those recommended by the manufacturer. The objective of the study was to assess the analytic performance of the hc2 test for the detection of high-risk HPV DNA from cells stored in the new Novaprep® HQ+ medium. Repeatability, reproducibility, method comparison and stability (-20 °C, +4 °C, +20 °C and +40 °C up to six months) were evaluated from HPV16 and HPV18 positive cell lines diluted in the Novaprep® HQ+ medium and the reference Specimen Transport Medium (STM). A series of cervical samples with atypical squamous cells of undetermined significance (ASC-US) cytology and stored in the Novaprep® HQ+ medium was also tested. Coefficients of variation for repeatability and reproducibility were less than 8 %. Method comparison showed perfect agreement in hc2 results when the HPV-positive cells were diluted in
Human Papillomavirus (HPV). Genital human papillomavirus (also called HPV) is the most common sexually transmitted infection (STI). There are more than 40 HPV types that can infect the genital areas of males and females. These HPV types can also infect the mouth and throat. Most people who become infected with HPV do not even know they have it. HPV is not the same as herpes or HIV (the virus that causes AIDS). These are all viruses that can be passed on during sex, but they cause different symptoms and health problems.. How do people get HPV?. HPV is passed on through genital contact, most often during vaginal and anal sex. HPV may also be passed on during oral sex and genital-to-genital contact. HPV can be passed on between straight and same-sex partners-even when the infected partner has no signs or symptoms. A person can have HPV even if years have passed since he or she had sexual contact with an infected person. Most infected persons do not realize they are infected or that they are passing ...
Genital human papillomavirus (HPV) is the most common of the STDs. There are over 40 types that can infect the genital areas of men and women, including the penis; vulva; anus; and the rectal, cervical, and vaginal linings. Genital warts (one type of HPV) are circumscribed, elevated skin lesions, usually seen on the external genitalia or near the anus. Approximately 20 million Americans are currently infected with HPV. Most persons do not realize they are infected or that they are passing the virus to their partner.. Etiology. Genital HPV is typically spread from person to person during intimate sexual contact. A pregnant woman can pass HPV to her neonate during vaginal delivery. Genital warts have a prolonged incubation period of 1 to 6 months and grow rapidly in the presence of heavy perspiration, poor hygiene, or pregnancy.. Signs and Symptoms. Most individuals with HPV do not develop symptoms. However, some types of HPV (usually known as "low-risk") are the cause of genital warts. Clients ...
Human papillomavirus (HPV) DNA testing with cytology triage is more sensitive than conventional cytology screening for detecting cervical lesions, according to a new study published online November 9 in the Journal of the National Cancer Institute. Cytology triage in HPV-positive women can improve specificity.. HPV DNA testing has shown higher sensitivity than conventional cytology screening for detecting cervical lesions, but it is uncertain whether the higher sensitivity is dependent on the age of the woman being screened.. Maarit Leinonen, M.D., of the Mass Screening Registry, Finnish Cancer Registry in Helsinki, and colleagues compared the age-specific performance of primary HPV DNA screening with that of conventional cytology screening. Finnish women aged 25-65 years were sent randomized invitations for HPV DNA testing with cytology triage or conventional screening.. Overall, primary HPV DNA screening with cytology triage was more sensitive than conventional screening for detecting cervical ...

Background: The establishment of the causal relationship between high-risk human papillomavirus (HR-HPV) infection and cervical cancer and its precursors has resulted in the development of HPV DNA detection systems. Currently, real-time PCR assays for the detection of HPV, such as the RealTime High Risk (HR) HPV assay (Abbott) and the cobas® 4800 HPV Test (Roche Molecular Diagnostics) are commercially available. However, none of them enables the detection and typing of all HR-HPV types in a clinical high-throughput setting. This paper describes the laboratory workflow and the validation of a type-specific real-time quantitative PCR (qPCR) assay for high-throughput HPV detection, genotyping and quantification. This assay is routinely applied in a liquid-based cytology screening setting (700 samples in 24 h) and was used in many epidemiological and clinical studies. Methods: The TaqMan-based qPCR assay enables the detection of 17 HPV genotypes and β-globin in seven multiplex reactions. These HPV ...

According to Gillison, most sexually active people-both men and women-contract HPV at some point in their lives. Why, she wondered, are the rates of HPV-positive head and neck cancer increasing, and why are they higher in men?. To answer these questions, Gillison examined the prevalence of oral HPV infection within the United States as part of the National Health and Nutrition Examination Survey.. She found that around seven percent of the population had an oral HPV infection, and men were three to five times more likely to have one than women. The key difference was in the relationship between the number of sexual partners and oral HPV infection. In men, the prevalence of oral HPV increases with each additional sexual partner until it reaches a plateau at 30 partners. In women, this plateau arrives more quickly, after only three sexual partners. Gillison attributes the overall rise in HPV-related cancers to the sexual revolution, which made it socially acceptable for people to have more ...
Introduction: Cervical cancer probably represents the best-studied human cancer caused by a viral infection and the causal association of this preventable cancer with human papilloma virus (HPV) is well established. Worldwide there is a scarcity of data regarding HPV prevalence with vast differences existing among populations. Objective: The aim of this meta-analysis was to determine the community-based HPV prevalence estimates among asymptomatic women from urban and rural set ups and in participants of cancer screening clinics. Study design: Systematic review and meta-analysis. Methods: PubMed-Medline, CINAHL, Scopus, and Google scholar were systematically searched for studies providing prevalence data for HPV infection among asymptomatic women between 1986 and 2016. Results: The final analysis included 32 studies comprising a population of 224,320 asymptomatic women. The overall pooled HPV prevalence was 11% (95% confidence interval (CI), 9%-12%). The pooled HPV prevalence of 11% (95% CI, 9%-11%)
