Filter by:This is a non-randomized, open label study to assess the reduction of Human Papillomavirus (HPV) infectivity and transmission in women positive for HPV16 and/or 18 in a cervical, oral and anal sample and vaccinated with 9vHPV/Gardasil-9™. The primary objective of the study is to demonstrate that vaccination with a 3-dose regimen of 9vHPV will reduce viral infectivity in HPV 16/18/16+18-positive women. This objective rests upon the hypothesis that, since vaccination with 9vHPV triggers the production of type-specific HPV antibodies which are exudated to the cervical and other infected mucosae, these antibodies adhere to and neutralize newly produced HPV 16/18 viral particles also present in the mucosae, thus reducing HPV's infective capacity and transmission to sexual partners. Secondary objectives of the study are: - To determine HPV antibody levels before and after vaccination for each of the 9vHPV-covered HPV types (6, 11, 16, 18, 31, 33, 45, 52, and 58), to distinguish an induced antibody production due to 9vHPV vaccination from a natural response to an HPV infection (when antibody production is expected to be lower). - To demonstrate viral infectivity reduction in HPV 16/18/16+18 after vaccination with 1-dose or 2-dose regimen of 9vHPV. Since antibody production after administration of 2 vaccine doses is not inferior to 3 doses, infectivity reduction is expected to be detected after 2 doses, and at least partially after one dose. The main endpoint of the study is the evaluation of the HPV infective capacity in cervical, anal and oral samples from HPV 16, 18 or 16+18-positive women, using a cellular assay that models in-vitro the cervical mucosa. In brief, the specific HPV biomarker E1^E4 is measured in HaCaT keratinocytes after being cultured with study samples and thus, exposed to HPV16/18 viral particles. A reduction in E1^E4 expression is expected for keratinocytes exposed to samples taken after vaccination with 9vHPV, since the specific HPV antibodies also present in these samples would bind HPV viral particles and prevent infection of cultured keratinocytes. Other endpoints included in the study are: - Detection of antibodies against HPV types covered by 9vHPV (6/11/16/18/31/33/45/52/58) by specific immunoassays (ELISA, cLIA). - HPV16/18 virion detection using ELISA and electronic microscopy. - HPV DNA detection and genotyping, using Anyplex HPV28. These endpoints are performed in cervical, anal and oral samples from HPV 16, 18 or 16+18-positive women - Titration of antibodies against HPV types covered by 9vHPV in serum samples from HPV 16, 18 or 16+18-positive women using ELISA or cLIA. A minimum of 39 and 30 women will be enrolled in two different study population cohorts, respectively: - RIFT-HPV 1 cohort: non-vaccinated adult women aged 35 years or older, positive for HPV16-, 18-, or double positive for 16 and 18, without lesion or with cervical intraepithelial neoplasia (CIN) 1/2 lesion eligible for conservative treatment. - RIFT-HPV 2 cohort: non-vaccinated adult women aged 27 years or older, positive for HPV16-, 18-, or double positive for 16 and 18, with multiple cervical, vulvar and/or anal lesions, with cervical lesions eligible for conservative treatment. Candidates to participate in the study are selected according to the HPV DNA test result in a cervical sample taken in their routine cervical cancer screening visit or in their routine gynaecological follow-up visit. There is no control group in this study: all participants are expected to complete all the per-protocol procedures in a total of 4 study visits within an average of 7 months' duration: Visit 1/ Day1, Visit 2/Month 2, Visit 3/Month 6, and Visit 4/Month 7. The study procedures are the following: - Pregnancy test on a urine sample in Visit 1 (pregnant women are excluded from the study). - Completion of a questionnaire about the participant's health status, use of oral contraception and sexual activity in Visits 1 and 4. - Cervical, anal oral and blood sample collection Visits 1, 2 and 3 before receiving 9vHPV vaccination, and in Visit 4. - Intramuscular administration of 9vHPV in a three-dose regimen in Visits 1, 2 and 3. Regarding data analysis for primary objective assessment, differences in the infectivity rate before (Day 1/ Visit 1) and after vaccination with 3 doses of 9vHPV (Month 7/ Visit 4) will be compared in cervical, anal and oral samples using non-parametric Wilcoxon signed rank test. The same assessment will be done in 1- or 2-dose vaccination scenario. Antibody production before and after vaccination will be summarized for each of the 9vHPV-covered HPV types.
This study is to investigate retrospectively the results of cervical cytology and high-risk human papillomavirus in the past 20 years recorded in Peking Union Medical College Hospital. The histological findings after cervical cancer screening were reviewed. The diagnostic values of different screening strategies were compared based on the results of cervical histology. The primary endpoint is the diagnosis of grade 2 cervical intraepithelial neoplasia (CIN2) or more severe lesions (CIN2+). The secondary endpoints include following objectives: (1) the invasive procedures needed according to the screening results; (2) the diagnosis of vaginal and/or vulval intraepithelial neoplasia; (3) the persistence and recurrence of human papillomavirus infection; and (4) the cost-effectiveness of screening strategies for CIN2+.
Based on the previous study of NCT03961191 and NCT03960879, we performed this trial to further confirm the accuracy of host DNA PAX1 and JAM3 methylation for cervical cancer screening. This study would provide profound basis for the approval of assay kit of DNA methylation in China for cervical screening. Three hospitals, including Peking Union Medical College Hospital, would enroll eligible patients in this study. The cervical cytology of 3 ml will be collected for the detection of DNA PAX1 and JAM3 methylation, and the results will compared with the cervical histological pathology, which is achieved after collection of cervical cytology, by surgeries including loop electrosurgical excision procedure, cervical conization, total hysterectomy and others. The methylation testing would be double-blinded in operators and analysts. The retrospective and prospective parts will enroll at least 120 patients and at least 339 patients, respectively.
Solid organ transplant recipients (OTRs) receive lifelong immunosuppressive therapy, which puts them at increased risk of cutaneous and mucosal cancers. In particular, OTRs have increased risk of skin cancer and cancers caused by human papillomavirus (HPV), including cervical cancer and oropharyngeal cancer. There is currently limited knowledge on risk factors for HPV infection and skin cancer in OTRs, and limited knowledge on the natural history of HPV infection and cervical neoplasia in OTRs compared with immunocompetent controls. With a continuously increasing number of OTRs, there is a growing need to improve our understanding of the long-term reactions to immunosuppression. The overall aim of this study is to investigate long term effects of immunosuppression on cutaneous and mucosal epithelium in Danish OTRs, including the risk of skin dysplasia and skin cancer, cervical and oral HPV infection and HPV-related dysplasia and cancer in OTRs. This study will be designed as a prospective observational cohort study based on clinical data and data from nationwide Danish registries. A total of 600 female OTRs, 600 male OTRs and 600 female controls will be included from Danish dermatology departments. The study aims to provide knowledge relevant for improving prevention of skin- and HPV-related cancers in OTRs, including personalized screening recommendations according to individual patient risk.
Cervical cancer is the fourth most common cancer in women worldwide. It is caused by an infection with human papillomavirus (HPV). A persistent infection with HPV is associated with increased risk of precancerous lesions, which may further develop into cervical cancer. To reduce the disease burden, accurate and timely diagnosis of cervical precancerous lesions are crucial. To identify cervical precancerous lesions, women are referred to colposcopy, which is the most important diagnostic tools to detect cervical precancerous lesions. It allows close visualization of the cervix in order to collect biopsies in the area called transformation zone (TZ), which is where precancerous lesions develop. It is essential for the physician to identify the TZ during colposcopy in order to obtain correct diagnosis. For women aged ≥50 this is often a challenge as TZ naturally with age, will retract further into the cervical canal, making the area for sampling invisible, and thereby the colposcopy inadequate. Consequently, this increases the risk of developing cancer due to diagnostic delay, and the risk of several colposcopy examinations or overtreatment (cone biopsy), before a final diagnosis is achieved. Few studies suggest that pretreatment with local vaginal estrogen prior to colposcopy may improve visualization of the TZ. Thereby, obtaining more accurate biopsies from the cervix, and thus making a more accurate and timely diagnosis in the first outpatient visit. The primary purpose of this study is to evaluate pre-diagnostic treatment with estrogen to improve the diagnosis of women with cervical precancerous lesions, in order to prevent cervical cancer. The study ia s randomized controlled double-blinded multicenter study. The investigators will use information from Danish National Patient registry, and data from the Danish Pathology Data Bank. Enrollment will take place at the Departments of Gynecology in Denmark. Eligible women aged ≥ 50 years will be randomized 1:1 to receive local vaginal estrogen or placebo prior to the colposcopic examination. The investigators believe the results will provide the prerequisite for obtaining correct diagnosis, and thereby provide basis for choosing the right individualized examination- and treatment plan. The results will also contribute with important knowledge, that may help reduce the incidence and mortality rate of cervical cancer.
Clinically, cervical precancerous lesion is one of the important diseases that endanger the life safety and fertility of young women. Women with histopathologically confirmed CIN2 need regular HPV, cervical cytology, and colposcopic biopsy if necessary to assess the outcome and progression of the disease. In this study, we intend to visit Fujian Maternal and Child Health Hospital, Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science & Technology and other hospitals, including 300 CIN2 participants aged 45 and below diagnosed by histopathology, and collect the remaining cervical secretions and cervical exfoliated cell samples after clinical examination, even if you do not participate in this clinical study. In clinical diagnosis, treatment and follow-up, it is also necessary to collect the above specimens for relevant medical tests. Therefore, it is of great clinical and scientific significance to explore the role of HPV integrated detection in predicting the prognosis of young women with CIN2.
The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objective of the study is to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes.
The aim of the trial is to determine whether organized screening with primary HPV analysis provide higher cancer protection in the age group 23-29 years compared to primary cytology.
Patients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS
Cervical cancer is one of the most common tumors in women, which seriously threatens women's life quality and safety. Human papilloma virus (HPV) infection is the most common cause of cervical cancer. Traditional HPV testing is based on the cells sample shed from the cervix. Recent studies have shown that urine HPV detection can be used as a new HPV detection method. This study intends to include patients undergoing TCT /HPV test/colposcopy in the department of gynecological diseases of the hospital, and collect urine samples and cervical swab samples. Sanger sequencing and cervical swab HPV test results were compared to evaluate the accuracy and clinical validity of urine HPV test combined with clinical diagnosis results of cases.
