High Risk Hpv

Human papilloma virus (HPV) is the most common sexually transmitted infection in the 21st century. It has been established that infections with specific HPV types are contributing factors to cervical cancer. Approximately 99.7% of cervical cancers are associated with high risk HPV types. HPV testing plays an important role in the prevention, by decreasing the prevalence and the mortality of cervical cancer. There are 16 HPV-centers operating in Hungary, in which patients undergo HPV screening, cervical exams, and treatment based on standardized guidelines. Patients and methods: The first HPV-center was founded in 2007 in Budapest, at the 2nd Department of Obstetrics and Gynecology, Semmelweis University. This study aimed to define the presence and prevalence of HPV-DNA in the cervical swab samples obtained from patients in our center. Authors conducted to assess the age-specific-prevalence, and HPV type distribution, the associated cervical abnormalities, comparing our results with international data. Results: Overall 1155 woman underwent HPV-testing and genotyping, using polymerase chain reaction. Overall, 55.5% of patients had positive test for HPV DNA types, in which 38.5% for high-risk HPV DNA. Overall prevalence was the highest among females aged 15 to 25years (62.9%). The most common HPV type found was the high risk type 16 (19.5% among the patients with positive HPV testing). Presence of high risk HPV with concurrent cervical cytological abnormality was in 32%. More than two-thirds of woman with cytological atypia (70.6%) were infected with two or more high risk HPV types. HPV 16 was detected in 32% of patients with cytological abnormalities. Conclusions: The results suggest that the prevalence of HPV in this study population exceeds the international data. The results attracts the attention the peak prevalence of the high risk types in the youngest age-group, and the higher risk of cervical abnormality in case of presence of two or more HPV types. The dominance of type 16 and 18 was predictable, but the strong attendance of type 51 and 31 among patients who had cytological atypia, was slightly surprising. Orv. Hetil., 2011, 152, 1804–1807.

There is high incidence of cervical cancer in Bihar, India. Vaccination for cervical cancer in developed countries has played a crucial role in limiting the incidence rate of cervical cancer worldwide. In consideration of debate on clinical efficacy of Human Papilloma Virus (HPV) vaccine in India, study on the prevalence of high risk HPV 16/18 strains in different regions of the nation becomes very crucial. Few individual states have started vaccination but centralised vaccination program does not exist due to lack of sufficient genotypic study of Human Papilloma Virus in different parts of India. Bihar is the third most populous state of India and HPV 16/18 distribution has not been reported yet. The nationwide data of HPV 16/18will help to develop a unified centralised vaccination program. We carried out a distribution study of high risk HPV type 16 and 18 in cervical cancer patients attending a tertiary care hospital of Bihar, India.HPV 16/18 types were analysed in cervical cancer tissues (n = 96) of patients attending the regional cancer hospital of Bihar. Tissue samples were analysed for HPV 16 and HPV 18 using a Real Time PCR technique. The results suggest very high prevalence of HPV 16/18. HPV was identified in all the samples (96/96). About, 74 (77.08%) samples presented with HPV 16 whereas, 16 (16.67%) of the samples presented with HPV 18. 6 Co-infection was presented in 6 (6.25%) of the samples of cervical cancer tissues. HPV 16/18 prevalence is more in the women aged between 41 to 61 years.We report 100% prevalence of HPV16/18 in the cervical cancer tissue samples. A way to minimise this gynaecological concern would be to introduce prophylactic vaccines and early screening in the state of Bihar. The data generated would be crucial in drafting for community screening of HPV. We strongly emphasize the prophylactic HPV Vaccination against HPV 16 to control the alarming rate of cervical cancer in one of the most populous state of India, Bihar.

High Risk Hpv

Human papillomaviruses (HPVs) are the etiological agents of several genital cancers, including cancer of the uterine cervix. The detection of HPV infection in genital samples may increase the sensitivity of primary and secondary screenings of cervical cancer. HPV testing may also improve the specificity of screening programs, resulting in the avoidance of overtreatment and cost savings for confirmatory procedures. The major determinants of clinical progression of HPV infection include persistence of HPV infection, involvement of high-risk HPV types, high HPV viral load, integration of viral DNA and presence of several potential cofactors. Signal amplification HPV-DNA detection techniques (Hybrid Capture II, Digene Corporation, USA) are standardized, commercially available, and capable of detecting several high-risk HPV types. They also increase the sensitivity of screening for high-grade lesions in combination with cytology. The sensitivity of these techniques to detect high-grade lesions is higher than that of cytology, but the referral rate for colposcopy is greater. These techniques are approved for the triage to colposcopy of women with cervical smears interpreted as atypical squamous cells of undetermined significance. Triage and screening for cervical cancer using HPV will probably be restricted to women aged 30 years or older because of the high prevalence of infection in younger women. Amplification techniques are ideal for epidemiological studies because they minimize the misclassification of HPV infection status. These techniques can detect low HPV burden infections. Consensus primers amplify most genital types in one reaction, and the reverse hybridization of amplicons with type-specific probes allows for the typing of HPV-positive samples. Consensus PCR assays are currently under evaluation for diagnostic purposes. HPV testing is currently implemented for the clinical management of women.

The primary underlying cause of cervical cancer is infection with one or more high-risk (HR) types of the human papilloma virus (HPV). Detection and typing of HPV have been commonly carried out by PCR-based assays, where HPV detection and typing are two separate procedures. Here, we present a multiplex PCR-based HPV typing assay that detects 20 HPV types (15 HR, 3 probably HR and 2 low risk) using type-specific primers and agarose gel electrophoresis. 46 cervical, urethral, and biopsy samples were analyzed by both Multiplex PCR and PGMY09/11 consensus PCR, and results were compared. 611 samples were further analyzed by Multiplex PCR, 282 were positive for HR HPV, and 101 showed multiple HR HPV infections. The relatively ease and economic accessibility of the method and its improved ability to detect high-risk HPV types in multiple HPV-infected samples make it an attractive option for HPV testing.

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.

Background: Cervical cancer is one of the most common types of cancer affecting women worldwide. Persistent HPV infection plays a major role in cervical cancer. The risk of cervical cancer has increased in parallel with the incidence of certain genotypes of human papilloma virus (HPV). Methods: The study was aimed to detect the distribution of HPV genotypes among cervical cancer patients from a specialized hospital in Dhaka, Bangladesh. HPV DNA testing was done by polymerase chain reaction (PCR) using SPF-10 broad-spectrum primers followed by genotyping by reverse hybridization using the INNO-LIPA genotyping system at the Department of Virology, Bangabandhu Sheikh Mujib Medical University, Dhaka. Results: HPV 16 was more prevalent (72.0%) in cervical cancer patients from Bangladesh followed by type 18 (6.0%) and 45 (2.0%). Genotype 16 and 18 alone and as co-infection were detected in 88.0% cases. Multiple HPV infection was found in 20% patients. Along with high risk (HR) HPV 16, 18 and 45 HR HPV 56, 39, 31 and 58 were also prevalent in multiple infections. Conclusion: Thus the study concluded that HR HPV 16 and HPV 18 were more prevalent genotypes among cervical cancer patients in a specialised hospital in Bangladesh. Along with HR HPV 16 and HPV 18, HR HPV 45, 56, 39, 31 and 58 were also prevalent Bangladesh Med Res Counc Bull 2019; 45: 86-92

SUMMARY Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Identification of precancerous lesions has been primarily by cytologic screening of cervical cells. Cellular abnormalities, however, may be missed or may not be sufficiently distinct, and a portion of patients with borderline or mildly dyskaryotic cytomorphology will have higher-grade disease identified by subsequent colposcopy and biopsy. Sensitive and specific molecular techniques that detect HPV DNA and distinguish high-risk HPV types from low-risk HPV types have been introduced as an adjunct to cytology. Earlier detection of high-risk HPV types may improve triage, treatment, and follow-up in infected patients. Currently, the clearest role for HPV DNA testing is to improve diagnostic accuracy and limit unnecessary colposcopy in patients with borderline or mildly abnormal cytologic test results.

Context Cervical cancer affects 12 000 women in the United States annually. However, despite its prevalence, there remains no good methodology to detect its recurrence. Objective To identify the role of cervicovaginal high-risk human papilloma virus (hr-HPV) testing in predicting cervical cancer recurrence. Design This is a retrospective study of patients who underwent hr-HPV testing as part of their routine surveillance for cervical cancer. Standard statistical analyses, including χ2 test and multivariable logistic regression, were performed with IBM SPSS 19.0. Results A total of 133 patients were identified, of whom 107 (80%) had squamous cell carcinoma. Ninety patients (68%) had bulky disease and were treated primarily with chemoradiation and brachytherapy. Of patients whose disease recurred, 5 patients (42%) had tested positive for hr-HPV during their surveillance period, compared to 13 patients (11%) for whom disease did not recur (relative risk: 3.88, P = .002). On multivariate logistic regression, hr-HPV status remained significantly predictive of disease recurrence (odds ratio: 12.3, P = .02, 95% confidence interval: 1.5–99.6). Using 2 × 2 table analysis, we found that while cervicovaginal cytology has limited specificity (5.7%) in predicting recurrence, the combination of cytology with hr-HPV testing increases the specificity of testing to 89.3%. Conclusions Persistence of hr-HPV is a risk factor for disease recurrence. High-risk–HPV testing is not routinely used during surveillance for cervical cancer, but this study suggests that large, prospective trials investigating the role of hr-HPV testing in cervical cancer surveillance are needed.

In the past decade an among aetiologic association between infection with high risk human papilloma virus and development of cervical cancer has been increased. The study was aimed at studying the prevalence and determinants of high risk human papilloma virus in these patients.Methods: This study was conducted for a period of one year to know the prevalence and determinants of high risk human papilloma virus in the patients attending gynaec out patient department. A total of 266 married women between 15-75 were randomly selected for the study.Results: There is high prevalence of HPV in low (43.3%)/mid (37.4%) socio economic class (17.6%). But the result was not statistically significant (p=0.149). higher prevalence of HPV was found in multiparas (39.4%) compared to multiparas (33.3%) which was not statistically significant (p=0.233). Husbands of 252 women were circumcised out of which 96 wives were positive for HPV DNA (38.1%). Among 14 women with no history of circumcision in their husband HPV DNA positive (28.6%). Correlation of cytology with HPV DNA among different age groups showed increasing prevalence with age but the result was not statistically significant (p=0.115). the result showed that age at marriage, higher the prevalence of HPV DNA. The result was statistically significant (p=0.017). with increasing state of education, the prevalence of HPV infection decreased, but the result was not statically significant (p=0.142).51.3% of women of who were not education were positive for HPV as against only 25% of graduates were HPV positive.Conclusions: Genital hygiene, genetic polymorphisms and other environmental cofactors among HPV DNA positive women, which prevent oncogenesis.

Abstract Background and aim This cross-sectional study investigated the prevalence and risk factors of high-risk human papilloma virus (HPV) infection, especially types 16 and 18, and cervical neoplasia in female Inflammatory bowel disease (IBD) patients. Methods From July 2014 to January 2017, sexually active, female, Chinese IBD patients (21–60 years) and age-matched controls underwent cervical ThinPrep cytology testing (TCT) and high-risk HPV-DNA detection, and completed questionnaires about awareness of cervical cancer and HPV. Cervical dysplasia was categorized as cervical intraepithelial neoplasia (CIN) 1, 2 and 3. Results Of 124 IBD patients (30 ulcerative colitis and 94 Crohn’s disease), 17 (13.7%) had high-risk HPV among whom 9 (7.3%) had HPV 16/18 infection and 4 (3.2%) had cervical CIN (3 CIN 3, 1 CIN 1) by pathology. Among 372 controls, 33 (8.9%) had high-risk HPV and only 1 (0.3%) had HPV 16 infection. Cervical TCT detected atypical squamous cells of unknown significance in one control; no control had CIN. The HPV 16/18 infection rate and CIN prevalence were significantly higher in IBD patients than controls (both P < 0.001). The HPV-infection rate was higher in patients administered methotrexate [P = 0.005, odds ratio (95% confidence interval) 4.76 (1.471–15.402)] or more than two immunosuppressants [P = 0.013, odds ratio (95% confidence interval) 3.64 (1.255–10.562)]. Thiopurine, steroid, infliximab and disease behavior/location were not associated with HPV infection. Only 29.3% of patients had undergone cervical-cancer screening. Awareness of HPV infection and HPV-related cervical cancer was poor (28.2%). Conclusions Female IBD patients are at increased risk of high-risk HPV infection and cervical neoplasia, which may be associated with immunosuppressants. Education and routine follow-up with HPV-DNA testing and TCT are recommended, especially in female Chinese IBD patients.
