Seroprevalence of mucosal and cutaneous human papillomavirus (HPV) types among children and adolescents in the general population in Germany. BMC Infect Dis 2022; 22:44. [PMID: 35012452 PMCID: PMC8751243 DOI: 10.1186/s12879-022-07028-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 12/28/2021] [Indexed: 11/30/2022] Open
Abstract
Background In Germany, HPV vaccination of adolescent girls was introduced in 2007. Nationally representative data on the distribution of vaccine-relevant HPV types in the pre-vaccination era are, however, only available for the adult population. To obtain data in children and adolescents, we assessed the prevalence and determinants of serological response to 16 different HPV types in a representative sample of 12,257 boys and girls aged 1–17 years living in Germany in 2003–2005. Methods Serum samples were tested for antibodies to nine mucosal and seven cutaneous HPV types. The samples had been collected during the nationally representative German Health Interview and Examination Survey for Children and Adolescents in 2003–2006. We calculated age- and gender-specific HPV seroprevalence. We used multivariable regression models to identify associations between demographic and behavioral characteristics and HPV seropositivity. Results We found low but non-zero seroprevalence for the majority of tested HPV types among children and adolescents in Germany. The overall seroprevalence of HPV-16 was 2.6%, with slightly higher values in adolescents. Seroprevalence of all mucosal types but HPV-6 ranged from 0.6% for HPV-33, to 6.4% for HPV-31 and did not differ by gender. We found high overall seroprevalence for HPV-6 with 24.8%. Cutaneous HPV type seroprevalence ranged from 4.0% for HPV-38 to 31.7% for HPV-1. In the majority of cutaneous types, seroprevalence did not differ between boys and girls, but increased sharply with age, (e.g., HPV-1 from 1.5% in 1–3-years-old to 45.1% in 10–11-years-old). Associations between behavioral factors and type-specific HPV prevalence were determined to be heterogeneous. Conclusions We report the first nationally representative data of naturally acquired HPV antibody reactivity in the pre-HPV-vaccination era among children and adolescents living in Germany. These data can be used as baseline estimates for evaluating the impact of the current HPV vaccination strategy targeting 9–14-years-old boys and girls.

Abstract
BACKGROUND Human papillomavirus (HPV) is the most prevalent sexually transmitted infection (STI) worldwide. Immunocompetent hosts have intact defense mechanisms to prevent HPV infection, but immunocompromised patients are at higher risk for complications, including HPV-related cancers. Most of these cancers originate from high-risk HPV strains in sexually active patients. CASE Here we present a case of an immunocompromised adolescent who developed cervical cancer despite no prior sexual activity and only ever having had low-risk type HPV on biopsy. SUMMARY AND CONCLUSIONS To our knowledge, this is the first case report of a cervical cancer arising from a low-risk HPV strain in an immunocompromised, non-sexually active adolescent. This case highlights the importance of preventive and screening mechanisms in immunocompromised populations, as they are have a higher probability of HPV-related complications, even in the absence of traditional risk factors.

Abstract
OBJECTIVES To evaluate the prevalence of HPV colonization in female adolescents and young adults after allogenic hematopoietic stem cell transplantation. STUDY DESIGN In this prospective pilot study, we enrolled 18 girls and young women aged 12-22 years cared for at the SCT (stem cell transplantation) Outpatient Clinic of the St. Anna children's hospital. Vaginal, buccal, and rectal HPV swabs were collected twice at intervals of 2-6 months at the Outpatient Clinic for children's and adolescents' gynecology of the University Clinic for Gynecology Vienna. RESULTS Overall, 3 (16.7%; 95% CL [≥0.0%; 33.9%]) of the 18 patients were vaginally HPV-positive at least at one timepoint. Among these three, two patients belonged to the smaller sub-group (3 patients) of patients after coitarche and one patient belonged to the larger one (15 patients) of patients prior to coitarche. In one of the three vaginally HPV-positive patients, we also found HPV DNA rectally. Orally, HPV DNA could not be detected at all. CONCLUSIONS According to the data of this study, vaginal, buccal, and rectal HPV colonization seems to be of little relevance in girls and young women after HSCT prior to coitarche. As expected, a higher risk for vaginal HPV colonization could be shown by trend for patients after coitarche, but also for those having been treated with total body irradiation as a conditioning regimen and for those showing signs of vaginal hypoestrogenization-which has not been published so far.

Abstract
Currently, three prophylactic HPV vaccines are commercially available to prevent HPV 16/18 infection and associated lesions. The aim of the study was to assess markers of HPV infection in women/girls before vaccination and to ascertain the prevalence and spectrum of post-vaccination HPV types. Three hundred and thirty subjects of which 75 were virgins were enrolled. Before the first dose of the HPV vaccine and 1, 3 and 5 years after the completion of HPV vaccination, the samples for cytology, HPV detection and anti-HPV antibody response were taken. At enrolment, HPV DNA was detected in 38% of sexually active girls/women. At the first, second and third follow-up, HPV DNA was found in 40, 45, and 39% of them. The seroprevalence rates to HPV 6, 11, 16 and 18 in these subjects were 31, 21, 18 and 10%. On the follow-up significantly higher levels of antibodies to HPV 16/18 were found after application of divalent vaccine. Results of the study demonstrate high prevalence of HPV infection in young women. In a substantial number of women, HPV-specific antibodies as well as high-risk HPV types were detected. HPV-specific antibodies were also frequently found in non-sexually active girls. The acquisition of HPV after the onset of sexual life was very fast.

Abstract
STUDY OBJECTIVE To compare the prevalence of human papillomavirus (HPV) genital infection among prepubertal children, sexually active and not sexually active adolescents, and assess potential risk factors for transmission. DESIGN Prospective study. SETTING Outpatient adolescent health clinic. PARTICIPANTS Ninety-five girls aged 2-21 years; 38 sexually active adolescents (group A), 28 not sexually active adolescents (group B), and 29 prepubertal children (group C). INTERVENTIONS Participants' vaginal or cervical specimens were tested for HPV with the CLART HPV 2 assay (Clinical Array Technology, Genomica, Madrid, Spain) and for cytological abnormalities with liquid-based cytology. MAIN OUTCOME MEASURES Differences in prevalence of low- and high-risk HPV infections among the 3 groups. RESULTS Genital HPV was detected in 37.9% (36/95) of all participants; 47.4% (18/38) of group A, 28.6% (8/28) of group B, and 34.5% (10/29)of group C (P = .27). Multiple HPV infection was detected in 26.3% (10/38), 10.7% (3/28), and 13.8% (4/29) of groups A, B, and C, respectively (P = .21). High-risk genotypes were detected in 47.4% (18/38), 28.6% (8/28), and 24.1% (7/29) of groups A, B, and C, respectively (P = .10). Main high-risk genotypes were HPV 16 (27%, 10/37), HPV 31 (21.6%, 8/37 ), HPV 35 (13.5%, 5/37), HPV 53 (13.5%, 5/37), and low-risk HPV 6 (18.9%, 7/37). Sexual activity was associated with increased risk for genital high-risk HPV infection (odds ratio = 3.41; 95% confidence interval, 1.19-9.78); specifically with HPV 33 and HPV 51. Forty percent of sexually active adolescents with normal cervical cytology were infected with high-risk HPV types. Family history of skin HPV was positively associated with genital HPV in the sexually active group (odds ratio = 2.01; 95% confidence interval, 1.17-3.46). CONCLUSION Timeline and target population for HPV vaccination might need to be reappraised, in view of significant nonsexual transmission of genital HPV so early in childhood.

Rogers C, Smith? RJ. Examining Provincial HPV Vaccination Schemes in Canada: Should We Standardise the Grade of Vaccination or the Number of Doses? INTERNATIONAL SCHOLARLY RESEARCH NOTICES 2015; 2015:170236.

Abstract
Human papillomavirus (HPV) infection is the most common sexually transmitted infection, which is linked to several cancers and genital warts. Depending on the Canadian province, the quadrivalent vaccine is given to girls in grades 4 through 10 with either a two- or three-dose schedule. We use a mathematical model to address the following research questions: (1) Does the grade at which the girls are vaccinated significantly affect the outcome of the program? (2) What coverage rate must the provinces reach in order to reduce the impact of HPV on the Canadian population? (3) What are the implications of vaccinating with two versus three doses? The model suggests the grade of vaccination and the number of doses do not make a significant difference to the outcome of the public vaccination program. The most significant factor is the coverage rate of children and adults. We recommend that provinces vaccinate as early as possible to avoid vaccine failure due to previous infection. We also recommend that the main focus of the program should be on obtaining a large enough coverage rate for children and/or adults in order to achieve the desired outcome with either two or three doses of the vaccine.

Abstract
OBJECTIVE To investigate the prevalence of high-risk (HR) and low-risk (LR) human papillomavirus (HPV) in prepuces of boys and men without any HPV related lesions. PATIENTS AND METHODS Between 2009 and 2011, a total collective of 250 boys and men were investigated in this prospective study. The samples were subdivided into 3 groups regarding their age, consisting of 125 (50%) children (0-10 years), 38 (15.2%) adolescents (11-20 years) and 87 (34.8%) adults (>20 years). In situ hybridization (ISH) was performed to detect HR and LR virus types within the epithelium, followed by microscopic interpretation and determination between episomal and integrative signal pattern. RESULTS Our results revealed high levels of HPV concentration (HR and LR) in all age groups: HR versus LR positivity was seen in 45.5 versus 35% (children), 60.6 versus 63.6% (adolescents) and 58.3 versus 48.6% (adults). The topmost rate of HR (59.8%)- and LR (50.6%)-positive probes was found in the group with high estimated sexual activity (>14 years). CONCLUSION Concerning the high prevalence of male HPV infection even in children, indicating non-sexual transmission pathways, inclusion of boys in the vaccination program seems to be required reducing their burden of HPV related disease.

Abstract
BACKGROUND Genital human papillomavirus (HPV) infection is believed to be primarily sexually transmitted. Few studies have documented the detection of HPV in the vagina before first vaginal intercourse. METHODS We used a longitudinally followed cohort of adolescent females without prior vaginal intercourse to examine the frequency of detection of vaginal HPV and the association between first reported HPV detection and noncoital sexual behaviors. RESULTS HPV was detected in 45.5% of subjects (10 of 22) before first vaginal sex. Seven of these 10 subjects reported noncoital behaviors that, in part, might have explained genital transmission. CONCLUSIONS HPV can be detected in the vagina before first sexual intercourse, highlighting the need for early vaccination.

Abstract
INTRODUCTION Monitoring the prevalence of type-specific HPV-DNA infections before and shortly after introduction of routine HPV vaccination offers the opportunity to evaluate early effects of the vaccination program. With this aim a cohort study was set up of 14- to 16-year-old girls eligible for HPV vaccination in the Netherlands. Annually, HPV-DNA and antibody status in vaginal self-samples and in serum respectively, will be studied among vaccinated (58%) and unvaccinated girls (42%). Here we present baseline data on vaginal HPV-DNA status in relation to serum antibodies. METHODS The 1800 enrolled girls filled out an internet-based questionnaire and provided a vaginal self-sample for genotype specific HPV-DNA detection using SPF(10) PCR amplification and reverse line probe hybridization. Furthermore, 64% of the girls provided a blood sample for HPV antibody analysis. IgG antibodies against virus-like particles were determined for 7 HPV genotypes. RESULTS At baseline, type-specific HPV-DNA was detected in 4.4% (n = 79) of the 1800 girls: 2.7% (n = 49) concerned a high risk HPV type (hrHPV-DNA). The three most common types were HPV type 16, 18 and 51 (40%). Out of the hrHPV-DNA positive girls, 32% was seropositive vs. 12% in HPV-DNA negative girls (p<0.001). Risk factors independently associated with hrHPV-DNA infection among the sexually active girls were age >15 years vs. 14-15 years (OR = 2.6 (1.2-5.9)), age of sexual debut <14 vs. above 14 years (OR = 3.0 (1.1-8.2)), total number of lifetime partners above two vs. less than two partners (OR = 3.2 (1.3-8.0)) and age of partner >17 vs. under 17 years (OR = 4.2 (1.5-13.0)). CONCLUSION A low hrHPV-DNA prevalence was found in the adolescent girls. The observed vs. expected age-related increase in HPV-DNA prevalence in this cohort in the coming years (with increased sexual activity) will provide understanding of the effect of HPV vaccination. Furthermore, this cohort study will offer the opportunity to improve knowledge of antibody responses following natural infection and vaccination.

Abstract
Human Papillomavirus (HPV) is very common in reproductive age women. It has been demonstrated that this infection can be transmitted from mother to infant. Evidence of HPV infection can be seen in infant and toddlers. A review of the literate was undertaken to examine the manner in which HPV can be transmitted, the rate at which transmission occurs, and if HPV can persist. The manifestations of HPV were also reviewed. It is not clear what effect the quadravalent HPV vaccine, given to mothers will have on HPV infections in infants.

Abstract
BACKGROUND Genital human papillomaviruses (HPV) include >40 sexually transmitted viruses. Most HPV infections do not progress to disease, but infection with certain types of HPV can cause cervical and other anogenital and oropharyngeal cancer, and other types of HPV are associated with anogenital warts. HPV vaccines prevent infection with HPV 16 and 18, which account for 70% of cases of cervical cancer, and HPV 6 and 11, which cause 90% of the cases of anogenital warts. METHODS Using data and self-collected cervicovaginal specimens from 4150 females, 14-59 years of age, from consecutive National Health and Nutrition Examination Surveys (2003-2006), we estimated the prevalence of type-specific HPV DNA and examined sociodemographic and sexual determinants. RESULTS The overall prevalence of HPV was 42.5% in females 14-59 years of age and varied significantly by age, race or ethnicity, and number of sex partners. Individual type prevalence was less than 7%, ranging from <0.5% through 6.5%. The most common type was nononcogenic HPV 62 (found in 6.5% of subjects), followed by HPV 53 and HPV 16 (4.7%), both of which are oncogenic types. The most prevalent species was nononcogenic α3. CONCLUSIONS HPV infection is common among US females, with the highest burden of infection found in young females 20-24 years of age. Monitoring trends in HPV type distribution will contribute to our understanding of the early impact of HPV vaccines.

Abstract
OBJECTIVES To characterize the epidemiology of genital human papillomavirus (HPV) infection in children without previous consensual sexual activity, comparing HPV prevalence by certainty of child sexual abuse (CSA). PATIENTS AND METHODS Patients presenting for evaluation of CSA in 8 sites in Atlanta, Houston, Harrisburg, and New York City were recruited along with patients presenting for unrelated health visits. CSA certainty was classified as definite, probable, possible, or no evidence following published guidelines and the results of history, physical examination, and laboratory tests. Urine and swabs of external genitalia were tested for HPV using L1 consensus polymerase chain reaction. RESULTS The study included 576 participants (89.9% female) aged 6 months to 13 years (mean: 7.9); 534 of whom were evaluated for CSA and 42 for unrelated reasons. Of those evaluated for CSA, 14 had genital warts. One or more HPV types were detected in 11.8% (61 of 517) of participants with adequate samples. HPV detection was more likely among abused participants (definite, probable, or possible) than among participants without evidence of CSA (13.7% and 1.3%, respectively; P < .0001) and increased with certainty of abuse (8.4%, 15.6%, and 14.5% in participants with possible, probable, and definite CSA, respectively; P < .0001). Participants aged 10 years or older had a higher prevalence of HPV (20.6%) than others (5.6%) (P < .0001). CSA, anogenital warts, and age were independently associated with HPV detection. CONCLUSIONS HPV detection was associated with CSA and increased with CSA certainty. In this population, genital HPV seemed to behave as a sexually transmitted infection.

Abstract
PURPOSE The aim of the study was to better characterize the natural history of human papillomavirus (HPV) infections in female adolescents. METHODS Female adolescents were enrolled in a longitudinal study. Self-vaginal samples were obtained every 3 months and tested for HPV. No participants received HPV vaccination. The findings for 40 female adolescents with the longest follow-up are reported in this study. RESULTS Average age at the time of enrollment was 15.2 years (range: 14-17; SD: .97). Mean duration of follow-up was 6.7 years (range: 4.4-9.2; SD: 1.2). In all, 32 participants (80%) reported being involved in sexual activity before their enrollment in the study; all reported being involved in sexual activity before enrollment; all reported being involved in sexual activity during follow-up. Baseline and cumulative prevalence of HPV among participants was 55% and 100%, respectively. During the study, each participant tested positive for a mean of 14 HPV types. Cumulatively, HPV 16 was detected in 29 of 40 participants (72.5%). Mean duration of high- and low-risk infections was 655.9 (median: 433) and 524.1 days (median: 334), respectively. CONCLUSION With prolonged follow-up, HPV infections with multiple types were found in all participants. Most had infection with HPV-16 or HPV-18, the oncogenic types represented in current vaccines, as well as infection with other oncogenic types. These data reinforce the importance of vaccine and non-vaccine strategies for prevention of HPV infections.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection. The effect of HPV on public health is especially related to the burden of anogenital cancers, most notably cervical cancer. Determinants of exposure to HPV are similar to those for most sexually transmitted infections, but determinants of susceptibility and infectivity are much less well established. Gaps exist in understanding of interactions between HPV, HIV, and other sexually transmitted infections. The roles of mucosal immunology, human microbiota at mucosal surfaces, host genetic factors and hormonal concentrations on HPV susceptibility and infectivity are poorly understood, as are the level of effectiveness of some primary or secondary preventive measures other than HPV vaccination (such as condoms, male circumcision, and combination antiretroviral therapy for HIV). Prospective couples studies, studies focusing on mucosal immunology, and in-vitro raft culture studies mimicking HPV infection might increase understanding of the dynamics of HPV transmission.

Abstract
PURPOSE OF REVIEW Studies of the human papillomavirus (HPV) vaccines, Cervarix and Gardasil provide strong evidence for the recommendation that HPV vaccines may minimize the incidence of cervical cancer over time. RECENT FINDINGS Both Cervarix and Gardasil provided more than 90% efficacy in preventing cervical intraepithelial neoplasia grade 2+ (CIN 2+) disease caused by HPV 16 and 18 in women 16-26 years who were seronegative and PCR-negative for HPV 16 and 18 at baseline. Cervarix provides more than 75% efficacy in independent cross-protection against persistent HPV 31 and 45, and 47% efficacy against HPV 33; whereas Gardasil offers 50% efficacy only against persistent HPV 31. A reduction in excisional therapies for CIN 2+ is nearly 70% for Cervarix, and 40% for Gardasil. Cervarix efficacy is documented to 6.4 years; Gardasil's to 5 years. Immunologically, Cervarix induces three to nine-fold higher peak-neutralizing antibody titers to HPV 16/18 than Gardasil, has significantly higher cervicovaginal mucus-neutralizing antibody presence than Gardasil, and significantly higher B memory cell response than Gardasil. Safety reports indicate injection site reactions for both Cervarix and Gardasil. Rare serious adverse events have been reported.

Abstract
Cervarix and Gardasil are two prophylactic HPV vaccines designed primarily for cervical cancer prevention. Cervarix is effective against HPV-16, -18, -31, -33 and -45, the five most common cancer-causing types, including most causes of adenocarcinoma for which we cannot screen adequately. Gardasil is effective against HPV-16, 18 and 31, three common squamous cell cancer-causing types. In addition, Gardasil is effective against HPV-6 and -11, causes of genital warts and respiratory papillomatosis. The most important determinant of vaccine impact to reduce cervical cancer is its duration of efficacy. To date, Cervarix's efficacy is proven for 6.4 years and Gardasil's for 5 years.
