Condyloma acuminata represents an epidermal manifestation, associated with the epidermotropic human papillomavirus (HPV). They have been reported as the most common sexually transmitted disease, with prevalence exceeding 50%, increased up to 4 times, within the last two decades, as the most common side of affection are the penis, vulva, vagina, cervix, perineum, and perianal area, with increased prevalence in young, sexually active individuals. Increased attention should be focused on lesions, caused by types, with moderate (33, 35, 39, 40, 43, 45, 51-56, 58) or high risk potential (types 16, 18) for malignant transformation, leading to further development of cancers of anus, vagina, vulva and penis, as well as cancers of the head and neck...

Cervical cancer is a leading cause of cancer mortality in women worldwide. Human papillomavirus (HPV) types 16 and 18 cause about 70% of all cervical cancers. Clinical trials have demonstrated that three doses of either commercially available HPV vaccine, Cervarix or Gardasil, prevent most new HPV 16/18 infections and associated precancerous lesions. Based on evidence of immunological non-inferiority, 2-dose regimens have been licensed for adolescents in the United States, European Union, and elsewhere. However, if a single dose were effective, vaccine costs would be reduced substantially and the logistics of vaccination would be greatly simplified, enabling vaccination programs in developing countries...

Recurrent respiratory papillomatosis (RRP) of the larynx represents a significant disease burden to patients and the healthcare system The use of HPV 6/11/16/18 vaccination (Gardasil® ) has previously been thought to impact on disease burden in patients with RRP. Gardasil® vaccination did not impact on the number of endolaryngeal surgical procedures required, the interval between procedures, or the number of patients who achieved disease remission in comparison to a control cohort. This study indicates Gardasil® vaccination does not appear to have any effect on disease burden in patients with RRP...

HPV vaccine Gardasil© is offered to girls in first year of secondary school in Ireland. We aimed to determine the association between HPV vaccine uptake among girls for academic year 2013/2014, by school and school characteristics: socioeconomic disadvantage and religious ethos. The National Schools Immunisation System (SIS) was searched to determine HPV vaccine uptake in schools for 2013/2014 (prior to recent anti-HPV vaccine publicity). The disadvantaged status and ethos of each school was added to the report...

BACKGROUND: Human papillomavirus infection is a global social burden that, every year, leads to thousands new diagnosis of cancer. The introduction of a protocol of immunization, with Gardasil and Cervarix vaccines, has radically changed the way this infection easily spreads among people. Even though vaccination is only preventive and not therapeutic, it is a strong tool capable to avoid the consequences that this pathogen could cause. Gardasil vaccine is not free from side effects and the duration of immunity is not always well determined...

BACKGROUND: Gardasil®, a quadrivalent vaccine targeting low-risk (6, 11) and high-risk (16, 18) human papillomaviruses (HPV), has been offered to 11-14 year-old schoolgirls in Switzerland since 2008. To evaluate its success and its potential impact on cervical cancer screening, HPV genotypes were examined in 18-year-old girls five years later (sub-study 1) and in outpatients participating to cervical cancer screening before and after vaccine implementation (sub-study 2). METHODS: For sub-study 1, 3726 females aged 18 in 2013 were invited to fill a questionnaire on personal demographics and HPV risk factors and to provide a self-collected cervicovaginal sample for HPV genotyping and Chlamydia trachomatis PCR...

Human papillomavirus (HPV) infection is a frequent cause of malignant and non-malignant disease, in particular among persons with HIV. HPV serotype-specific anti L1 antibodies protect against HPV infection but little is known about prophylactic HPV vaccine-induced cell-mediated immunity against HPV in high-risk individuals. We recently showed that both HPV vaccines (Gardasil® and Cervarix®) induce solid, serological immune responses in HIV-infected persons. This study aimed to characterize HPV-specific CD4 T cells in HIV-infected HPV-vaccine recipients, T cell responses being critical for B cell activation and antibody-isotype switching...

A 50-year-old man with widespread manifestation of warts and distinct pruritus for the last 5 years was diagnosed with a reactivated human papillomavirus (HPV) infection by three, genetically verified types (6, 16, 18), which are included in the vaccine Gardasil®. Conventional treatment was not successful, but a rapid and significant reduction of the skin manifestation was observed after vaccination with Gardasil®. To what extent therapy-resistant infections with HPV can be influenced through an active HPV vaccination should be investigated in future trials...

BACKGROUND: Human papilloma virus vaccines are a safe and effective tool for reducing HPV infections that can cause cervical cancer. However, uptake of these vaccines has been suboptimal, with many people holding negative beliefs and misconceptions. Such beliefs have been linked with the experience of unpleasant side effects following medical treatment, and media coverage may heighten such concerns. METHODS: The present study sought to assess the influence of news coverage (number of news articles per month) on adverse event reporting in response to Gardasil vaccination in New Zealand over a 7...

BACKGROUND: The incidence of oropharyngeal cancer (OPC) in New Zealand (NZ) has more than doubled over the last 14 years with 126 cases in 2010. Overseas studies have shown that human papillomavirus (HPV) plays a significant role in the development of these cancers. However, the role of HPV in OPC and the burden on the NZ health system is unclear. AIM: The aim of the study was to determine the prevalence and the genotypes of HPV associated with OPC in New Zealand...

Human papillomaviruses (HPVs) cause approximately 5% of cancer cases worldwide. Fortunately, three prophylactic vaccines have been approved to protect against HPV infections. Gardasil-9, the most recent HPV vaccine, is predicted to offer protection against the HPV types that cause ∼90% of cervical cancer, 86% of HPV-associated penile cancers, and ∼93% of HPV-associated head & neck cancers. As an alternative to Gardasil-9, we developed and tested a novel candidate vaccine targeting conserved epitopes in the HPV minor capsid protein, L2...

OBJECTIVES: Recurrent respiratory papillomatosis (RRP) is a rare disease, but one with severe morbidity and occasional mortality. The aetiological agent is human papillomavirus (HPV), and HPV types 6 and 11 account for over 90% of all cases. In the active phase of the disease, patients require multiple hospital admissions for surgical removal or ablation of these benign tumors, which are likely to obstruct the airways if left unchecked. Long-term sequelae include scarring of the vocal cords, change in voice timbre, or even muteness if a tracheostomy is required...

Virus-like particles (VLPs) have made giant strides in the field of vaccinology over the last three decades. VLPs constitute versatile tools in vaccine development due to their favourable immunological characteristics such as their size, repetitive surface geometry, ability to induce both innate and adaptive immune responses as well as being safe templates with favourable economics. Several VLP-based vaccines are commercially available including vaccines against Human Papilloma Virus (HPV) such as Cervarix® , Gardasil® & Gardasil9® and Hepatitis B Virus (HBV) including the 3rd generation Sci-B-Vac™...

OBJECTIVE: Although it has been shown that prophylactic vaccination can induce genital immunity, there is inadequate information on human papillomavirus (HPV) vaccine-induced oral immunity, which is of particular interest due to HPV-associated oropharyngeal malignancies and recurrent respiratory papillomatosis. Therefore, we assessed the efficacy of various HPV vaccines against oral HPV pseudovirus (PsV) infection in mice. STUDY DESIGN: Preclinical scientific investigation...

BACKGROUND: In our first report on antibody levels in middle-aged and older men with recurrent laryngeal papillomatosis (RLP), we reported increases in human papillomavirus (HPV) antibody levels similar to those seen in adult women and young men. We posited that HPV antibodies produced in laryngeal mucus by Gardasil would prevent postoperative reinfection in patients with RLP. STUDY DESIGN: This is a case series study. PURPOSE: The purpose of this study was to examine whether Gardasil injection effectively inhibits recurrence of RLP...

Current licensed and commercially available prophylactic human papillomavirus (HPV) vaccines (Cervarix and quadrivalent/nine valents Gardasil) are based on major capsid protein L1 virus-like particles (VLPs) production which are expensive and type specific. Minor capsid L2-RG1 linear epitope (17-36) is a known candidate for induction of cross-neutralizing antibodies to develop low-cost pan-HPV vaccines. Herein, we report construction and expression of a three tandem repeats of L2-RG1 derived from HPV16 and 18 fused with the same head to tail pattern (HPV16:17-36×3+ HPV18:17-36×3; hereafter termed dual-type fusion L2 peptide) in E...

The human papillomavirus (HPV) is a major public health concern affecting both females and males. HPV is associated with cervical, anal, head and neck cancers. About 99% of all cervical cancers are related to HPV. HPV vaccines, Gardasil, Cervarix, and Gardasil 9 are used in the primary prevention of HPV related cancers. Gardasil and Gardasil 9 are available for use in both females and males ages 9 to 26, while Cervarix is available for females ages 9 to 25. Gardasil 9 was approved by the FDA for prevention against additional HPV types...

Capillary electrophoresis (CE) for HPV-VLP quantitation is a very interesting alternative technique compared to those currently used in viral analysis, such as SDS-PAGE, Western blot or protein assay that are destructive and semi-quantitative or non specific. In this study, the quantitative performance of the CE method was evaluated. A main issue in virus quantitation is the absence of reference material. Therefore, the concentration of a HPV16-VLP sample produced in the laboratory was determined using ELISA with Gardasil(®), after adjuvant dissolution, as reference material and conformational H16...
