Active clinical trials for "Papillomavirus Infections"

This transmission pilot study is a prospective study to determine feasibility of enrolling female partners into an international transmission study. Companion study to MCC-13930.

The purpose of the study is to determine the Human Papillomavirus (HPV) prevalence and HPV type distribution among women aged >= 18 years, attending out-patient health services for gynaecological examination and who agree to HPV testing in Egypt .

The purpose of this study is to determine the Human Papillomavirus (HPV) prevalence and HPV type distribution among women ≥ 20 years of age attending routine cervical screening and among women ≥ 16 years of age presenting for post-natal check up in the Kingdom of Bahrain.

The purpose of this study is to gain a better understanding of the body's response to a human papillomavirus (HPV) (sexually transmitted disease), vaccine and booster shot. The study will also determine factors related to adolescents not following vaccination schedules. The HPV vaccine requires 3 doses (shots). Girls sometimes receive the 3 shots at the recommended time and sometimes girls receive the shots at non-recommended times. This study will evaluate if getting the shots at non-recommended times affects the level of protection provided by the vaccine. Participants will include about 1400 girls 9-17 years old receiving a third dose of HPV vaccine from their primary care clinician. The parent/legal guardian of each subject may answer a questionnaire related to the vaccine schedule. Study procedures include: medical history, questionnaires and blood draws. Participants will be involved in the study for about 6 months from time of enrollment.

HPV infection is associated with cervical and other anogenital cancers. HPV may also be associated with the development of prostate cancer. The purpose of the study is to determine the prevalence of HPV infection in men living in South Dakota.

HPV infection has been recognized as the most prevalent sexual transmitted infection worldwide. Burden of many HPV related diseases is well known particularly regarding the different associated cancers (cervical, anal, vaginal, vulvar, oro-pharyngeal) (3) ; however, there is much less available information on the general burden of genital warts, the associated HPV types, the costs of related medical treatments and the knowledge and perceptions towards the disease and its prevention. Objectives: To determine the HPV genotypes distribution in genital warts in the study population. To assess the knowledge about transmission & prevention of HPV infection related diseases To determine the direct medical costs of genital warts attention.

The purpose of this study is to determine the prevalence and type distribution of genital human papillomavirus (HPV) infection in Tanzanian men.

The purpose of this study is to determine whether a model can be created to predict the progression of early anal cancer precursor lesions in HIV using potential predictors such as: HIV treatment history, smoking history, sexual history, human papillomavirus viral load, human papillomavirus protein expression, and cell markers associated with progression of HPV-related lesions.

Purpose Our study involves two hypotheses. One is that genital infection with HPV is associated with increased risk of miscarriage and preterm birth. The second hypothesis is that human papillomavirus can ascend from the vagina to the uterus through the cervix and cross the placental barrier. We wish to verify these hypotheses in our studies. This study will determine the prevalence of HPV in Danish pregnant women and examine HPV's role in the aetiology of spontaneous abortion and preterm birth.

This study evaluates the positive and negative predictive value of E6/E7 mRNA expression for anal HSIL and its capacity to predict incident HSIL in HIV + MSM. We also analyse the cost-effectiveness of this new screening strategy. It is an ambispective study with 355 participants and a follow-up period of 2 to 5 years.
