RESUMO

PURPOSE: Human papillomavirus (HPV) is the most common sexually transmitted infection, responsible for multiple HPV-related diseases, including almost all cervical cancers. The highly effective HPV vaccination has been recommended under the German HPV national immunization program (NIP) since 2007 and is reimbursed by health insurances. Vaccination uptake rates, however, remain suboptimal and data on the real-world impact of HPV vaccination in Germany are lacking. This study aims to demonstrate the population-level impact of Germany's NIP on HPV-related anogenital diseases among young women. METHODS: Retrospective claims data analysis using a classic impact study design comparing disease prevalence among 28- to 33-year-old women before and after introduction of the HPV-immunization program in Germany. Claims data representing approximately two thirds of German health insurances were used. HPV-related disease outcomes included cervical cancer and high grade precancers (cervical intraepithelial neoplasia (CIN) 2+), anogenital warts, as well as vulvar, vaginal, and anal precancer/cancer. RESULTS: Significant declines were seen for CIN2+, anogenital warts, and vaginal precancer/cancer. Prevalence of CIN2+ declined 51.1% from 0.92% (95% CI = 0.78%, 1.08%) to 0.45% (95% CI = 0.38%, 0.53%). There was a 38.6% decline in anogenital warts prevalence from 0.44% (95% CI = 0.36%, 0.54%) to 0.27% (95% CI = 0.22%, 0.32%) and 75.0% decline in vaginal precancer/cancer prevalence from 0.04% (95% CI = 0.02%, 0.07%) to 0.01% (95% CI = 0.00%, 0.02%). CONCLUSION: The German HPV-immunization program has led to significant declines in female anogenital disease among young women in Germany, highlighting the importance of the vaccination. Moreover, the data suggest that increasing vaccination coverage in Germany could further strengthen the public-health impact of its HPV-immunization program.

RESUMO

BACKGROUND: Genital warts, besides their importance as symptoms of sexually transmitted infections, can also threaten the sexual health of couples. The purpose of this study was to explore the sexual compatibility in women with active genital warts. METHODS: A qualitative study with a conventional content analysis approach in Tehran, Iran, from January 2019 to February 2020 was conducted on a purposeful sample of data saturation achieved after interviewing 14 women with genital warts, 2 couples and 3 dermatologists, 1 sexologist and 1 infectious disease specialist. Data were collected through unstructured interviews and analyzed using conventional content analysis approach. RESULTS: After data analysis 224 initial codes, 5 main categories "change in the frequency of sexual activity", "changing types of sexual intercourse", "protected sexual intercourse", "concealment of lesions", "focusing on personal hygiene by couples after sexual activity" and finally a central theme of "adaptation to challenges of sexual intercourse" were extracted. CONCLUSIONS: This study revealed the perceptions and experiences of women with active genital warts about the process of their sexual adaptation. The main concepts found in this study focus on challenges related to sexual intercourse. It seems that recognizing women's sexual adaptation challenges after getting genital warts may help them take effective and practical measures to improve their sexual compatibility and health.

RESUMO

BACKGROUND: Human papillomavirus (HPV) infected keratinocyte dysfunction results in the formation of genital warts, and the specific role of Sonic hedgehog (SHh) signaling in genital warts remains elusive. Thus, this study aimed to identify the correlation between wart formation and SHh signaling. MATERIALS AND METHODS: In this study, nine male patients with genital warts were recruited, and the expression of SHh and its downstream signal molecules Patched-1 and GLI family zinc finger 1 (Ptch1 and Gli1) was detected. Moreover, G2-phase cells in the collected genital warts samples were assessed with normal foreskin samples as a comparison. HPV6/11 were detected via in situ hybridization (ISH), and SHh expression of the corresponding paraffin sections was determined via immunohistochemical staining (IHC). In addition, an in vitro down-regulated SHh model was constructed by siRNA transfection of the HaCaT cell line, and the cell cycle was detected at 36 h by flow cytometry with propidium iodide staining. RESULTS: SHh, Ptch1, and Gli1 in warts were significantly downregulated in the condyloma acuminatum (CA) group compared to the normal foreskin group. G2-phase cells in the middle section of the spinous layer of CA wart tissues were significantly increased. Moreover, the expression of HPV-DNA was amplified and negatively correlated with SHh activity in CA wart tissues. Lastly, the downregulation of SHh-induced G2 arrest in vitro. CONCLUSIONS: The downregulation of the SHh signaling promotes HPV replication and the formation of warts by inducing G2/M arrest in the keratinocytes of CA.

RESUMO

Infantile perianal pyramidal protrusion (IPPP) is a benign condition generally noted in childhood but may persist for several years. Dermoscopy may help to distinguish it from other conditions, particularly genital warts. We report six cases of IPPP and describe the dermoscopic features that will distinguish these lesions from verrucae.

RESUMO

BACKGROUND: Condylomata acuminata, or genital warts (GW), are exceedingly prevalent, with human papilloma virus infection accounting for 90% of cases. It can be treated in a variety of methods, but the high recurrence rate and cervical scars make it difficult to choose the best treatment option. Hence, the study aims to find the effect of laser combined with 5-aminolevulinic acid (ALA) photodynamic therapy for condyloma acuminata in the vulva, vagina, and cervix. METHODS: A total of 106 female patients with GW of the vulva, vagina, and cervical condyloma acuminata were treated in the Dermatology Department of Subei People's Hospital in Yangzhou from May 2020 to July 2021. All these patients were treated with laser combined with 5-ALA photodynamic therapy to observe the therapeutic effect. RESULTS: About 84.9% of patients responded to the first session of ALA-photodynamic treatment. Five patients relapsed in the 2nd week, two patients relapsed in the 4th week, one relapsed in the 8th week, one relapsed in the 12th week, and the relapsed patients were given 1-3 times of photodynamic therapy again, and no recurrence was seen in the 24th week. After four courses of treatment in 106 patients, the wart clearance rate was 100%. CONCLUSION: Laser combined with 5-ALA photodynamic therapy for female vulva, vagina, and cervix condyloma acuminata has a reliable curative effect, low recurrence rate, few adverse reactions, and less pain. It is worth promoting in female vulva, vagina, and cervical condyloma acuminata.

RESUMO

Different therapeutic modalities for ano-genital warts (AGWs) are available but data on the efficacy of 5-fluorouracil 0.5%/salicylic acid 10% solution (5FU/SAsol) in the treatment of AGWs are scarse. We enrolled 17 patients with AGWs (14 males, 3 females with a mean age of 34.2 years) who gave written informed consent to the off-label use of topical 5FU/Sasol. Response to treatment was assessed based on the AGWs number: complete if there was complete clearance of the lesions; partial if there was >50% decrease in the lesion number and none if there was <50% decrease in the lesion number. Considering together partial and complete treatment response, 88% of the patients at 3 months and 94% at 6 months benefited from the 5FU/SAsol treatment. 5FU/SAsol was well tolerated by all the patients except one who experienced a burning sensation immediately after the application. The clearance rate that we found for 5-FU/SAsol after 3 months of treatment is comparable with that of the other commonly used therapeutic modalities (liquid nitrogen cryotherapy, imiquimod 5% cream). However, several patients on imiquimod and almost who underwent cryotherapy reported pain as adverse event while a mild pain was rarely reported with 5-FU/Sasol. In conclusion, although nowadays in Italy 5-FU/SAsol is marketed only for the treatment of actinic keratosis, our study described its effectiveness and tolerability also in the treatment of AGWs. Our data suggest that 5-FU/SAsol should be considered not only in case of resistant/recurrent AGWs but also as the first therapeutic option, especially when the number of lesions is small.

RESUMO

BACKGROUND: Genital wart (GW) is known as an infectious disease. Besides the infection, it is associated with a higher risk of cervical neoplasia and cancer in the infected population. The present research aimed to explore the predictors of GW preventive behaviors based on the health belief model (HBM). METHODS: The present analytical and cross-sectional research was conducted in 2019 among 720 women between 15 and 49 years of age in Bandar Abbas in the south of Iran. The sample was selected in a multi-stratified clustering method. The participants responded to a reliable and valid researcher-made questionnaire which explored demographic information, knowledge-related items and the model constructs. A multivariate linear regression analysis was run to determine the predictors of adopting GW preventive behaviors. A path analysis was also run to test the direct and indirect effects of the model constructs on the dependent variable. RESULTS: The mean and standard deviation of participants' age was 30.43 ± 8.697 years. As Pearson's correlation coefficients showed, knowledge (r = 0.197, p < 0.001), perceived susceptibility (r = 0.434, p < 0.001), severity (r = 0.463, p < 0.001) and self-efficacy (r = 0.434, p < 0.001) were significantly correlated with the adoption of GWs preventive behaviors. Multiple linear regression analysis showed that self-efficacy (B = - 0.010, p < 0.001), perceived susceptibility (B = 0.070, p < 0.001) and severity (B = 0.078, p < 0.001) were the predictors of GW preventive behaviors. Path analysis showed that perceived susceptibility, severity and self-efficacy directly affected healthy behaviors while perceived benefits and barriers indirectly affected the preventive behaviors. CONCLUSIONS: The present findings help to promote knowledge of the predictors of GW preventive behaviors. HBM can be a useful theoretical framework to evaluate the preventive behavior of the disease and help to reduce the rate of sexually-transmitted infections including GW.

RESUMO

BACKGROUND: Human papillomavirus is the most common sexually transmitted infection, usually passing from one person to another after the first sexual activity. Infection with this virus and the occurrence of genital warts (GWs) could have several effects on patients' health. This study was performed to evaluate the sexual function and sexual quality of life (SQOL) in men with GWs. METHODS: This cross-sectional study was conducted from September 2019 to March 2020 with a sample size of 105 men with GWs in the dermatology clinic of Shahid Faghihi Hospital in Shiraz University of Medical Sciences, Iran. Data were collected using a demographic questionnaire, the International Index of Erectile Function (IIEF), and the Sexual Quality of Life-Men (SQOL-M) questionnaires and analyzed by descriptive and inferential tests with SPSS software version 22. RESULTS: The mean score for overall sexual function in men was 48.50 ± 8.89. About 35.2% of men had overall sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. The mean score for SQOL-M was 38.36 ± 14.47, and 56.2% of them had a good SQOL. CONCLUSIONS: GWs affected men's erection more than the other sexual function domains. SD in men with GWs has a significant impact on their SQOL and ED was associated with impaired SQOL. Therefore, it is recommended to pay more attention to SD screening alongside SQOL assessment of men with GW.

In this cross-sectional study, we examined the sexual function and sexual quality of life (SQOL) in men with GWs. Of the 105 men, 35.2% had sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. 56.2% of them had a good SQOL. SD in men with GWs has a significant impact on their SQOL. Therefore, it is recommended that assessment of sexual function and SQOL should be done when men with GWs refer to health services.

RESUMO

BACKGROUND AND OBJECTIVE: Genital warts are caused by the human papillomavirus (HPV), whose genotypes have traditionally been classified as low risk or high risk (oncogenic). The first 2 prophylactic vaccines included the most common genotypes at the time: HPV-6, HPV-11, HPV-16, and HPV-18. The aim of this study was to evaluate the prevalence of HPV types in our setting 10 years after the introduction of HPV vaccines. MATERIAL AND METHODS: Descriptive, observational, retrospective study of patients diagnosed with genital warts at the sexually transmitted infection unit of a dermatology department between January 2016 and June 2019. RESULTS: In total, 362 patients were diagnosed with genital warts during the study period, and 212 (58.6%) underwent genotyping. Thirty-two distinct HPV types were observed, the most common being HPV-6, HPV-11, HPV-16, and HPV-42. HPV DNA was detected in 93.9% of the samples analyzed, and there were 299 genotypes (mean, 1.5 per patient). Overall, 26.6% of patients had more than a single HPV genotype, while 24.1% had at least 1 high-risk type. No significant associations were found between the presence of high-risk HPV types and any of the study variables. At least 2 of the 4 HPV types targeted in the original vaccines were detected in 94.1% of lesions. CONCLUSIONS: Compared to 10 years ago, the prevalences of HPV types included in the first 2 prophylactic vaccines have decreased, while the proportion of patients with at least 1 of the 4 most common types has remained unchanged. We also observed a slight increase in infections with multiple HPV types or at least 1 high-risk type.

RESUMO

BACKGROUND: Increasing evidence suggests that 1-dose human papillomavirus (HPV) vaccination may protect significantly against HPV-related disease. We provide nationwide, real-world data on the risk of genital warts (GWs) after <3 vaccine doses. METHODS: All Danish women born in 1985-2003 were identified, and individual-level vaccination data were retrieved. The cohort was followed up for first occurrence of GWs until 31 December 2016. Using Poisson regression, we calculated incidence rates (IRs) of GWs per 100 000 person-years and IR ratios (IRRs) with corresponding 95% confidence intervals (CIs) for GWs, according to vaccination status, age at first dose, and calendar time. RESULTS: The cohort comprised 1 076 945 girls and women, of whom 485 408 were vaccinated. For girls initiating vaccination at age 12-14 years and 15-16 years, 1-dose vaccine effectiveness (VE) was 71% (IRR = 0.29; 95% CI, .22-.38) and 62% (0.38; .29-.49), respectively, compared with unvaccinated girls. In the same age groups, 2-dose VE was 78% (IRR, 0.22; 95% CI, .18-.26) and 68% (0.32; .26-.38), respectively. After 2009, the IRRs for 3 versus 1 dose and 2 versus 1 dose increased towards unity over calendar time, being 0.69 (95% CI, .57-.84) and 0.86 (.68-1.08) in 2016, respectively. CONCLUSIONS: In this study, 1 or 2 doses of quadrivalent HPV vaccine was associated with substantial protection against GWs in girls vaccinated at age ≤16 years. The 1-dose VE approached that of 3 or 2 doses over calendar time, probably reflecting the impact of herd protection.

RESUMO

BACKGROUND: Genital warts are a common and highly contagious sexually transmitted disease. They have a large economic burden and affect several aspects of quality of life. Incidence data underestimate the real occurrence of genital warts because this infection is often under-reported, mostly due to their specific characteristics such as the asymptomatic course. METHODS: Genital warts cases for the analysis were obtained from the Catalan public health system database (SIDIAP) for the period 2009-2016. People under 15 and over 94 years old were excluded from the analysis as the incidence of genital warts in this population is negligible. This work introduces a time series model based on a mixture of two distributions, capable of detecting the presence of under-reporting in the data. In order to identify potential differences in the magnitude of the under-reporting issue depending on sex and age, these covariates were included in the model. RESULTS: This work shows that only about 80% in average of genital warts incidence in Catalunya in the period 2009-2016 was registered, although the frequency of under-reporting has been decreasing over the study period. It can also be seen that this issue has a deeper impact on women over 30 years old. CONCLUSIONS: Although this study shows that the quality of the registered data has improved over the considered period of time, the Catalan public health system is underestimating genital warts real burden in almost 10,000 cases, around 23% of the registered cases. The total annual cost is underestimated in about 10 million Euros respect the 54 million Euros annually devoted to genital warts in Catalunya, representing 0.4% of the total budget.

RESUMO

BACKGROUND: The introduction of human papillomavirus (HPV) vaccination has resulted in a remarkable decline of genital warts in women and men, but in Germany historical rates of vaccination are relatively low. We report long-term surveillance data on changes in HPV 6 and HPV 11 infection and the prevalence of genital warts in young women in the Wolfsburg HPV epidemiological study (WOLVES). METHODS: Women born in 1983/84, 1988/89, and 1993/94 participated in four cohorts between 2009/10 and 2014/15. Quadrivalent vaccination coverage and prevalence of HPV 6/11 infection and genital warts are reported for participants aged 19-22 years and 24-27 years at the time of sample collection. Statistical analyses were done to compare similarly aged participants using 2 × 2 contingency tables (Röhmel-Mansmann unconditional exact test; two-side alpha of 0.05). RESULTS: A total of 2456 women were recruited. Between 2010 and 2015, there was a statistically significant decrease in the prevalence of HPV 6 infection among women aged 24-27 years (2.1% versus 0.0%; P < 0.0001) and women aged 19-22 years (2.0% versus 0.0%; P = 0.0056). There was no significant decline in HPV 11 infection. In total, 52 of 2341 participants were diagnosed with genital warts. There was a statistically significant drop in the risk of developing genital warts in women aged 24-27 years between 2010 and 2015 (4.7% versus 1.7%, respectively; P = 0.0018). The overall risk of developing genital warts in women aged 19-27 years decreased from 3.1% in 2010 to 1.2% in 2015 (P = 0.0022). CONCLUSIONS: An increase in vaccination coverage was associated with a decreased prevalence of genital warts in young women. A protective effect greater than herd immunity alone was seen despite low vaccination rates. Quadrivalent vaccine had a protective effect on genital HPV 6 infection and an almost fully protective effect on the development of genital warts in the youngest population.

RESUMO

BACKGROUND: Combined with cancer screening programs, vaccination against human papillomavirus (HPV) can significantly reduce the high health and economic burden of HPV-related disease in Japan. The objective of this study was to assess the health impact and cost effectiveness of routine and catch-up vaccination of girls and women aged 11-26 years with a 4-valent (4vHPV) or 9-valent HPV (9vHPV) vaccine in Japan compared with no vaccination. METHODS: We used a mathematical model adapted to the population and healthcare settings in Japan. We compared no vaccination and routine vaccination of 12-16-year old girls with 1) 4vHPV vaccine, 2) 9vHPV vaccine, and 3) 9vHPV vaccine in addition to a temporary catch-up vaccination of 17-26 years old girls and women with 9vHPV. We estimated the expected number of disease cases and deaths, discounted (at 2% per year) future costs (in 2020 ¥) and discounted quality-adjusted life years (QALY), and incremental cost effectiveness ratios (ICER) of each strategy over a time horizon of 100 years. To test the robustness of the conclusions, we conducted scenario and sensitivity analyses. RESULTS: Over 100 years, compared with no vaccination, 9vHPV vaccination was projected to reduce the incidence of 9vHPV-related cervical cancer by 86% (from 15.24 new cases per 100,000 women in 2021 to 2.02 in 2121). A greater number of cervical cancer cases (484,248) and cancer-related deaths (50,102) were avoided through the described catch-up vaccination program. Routine HPV vaccination with 4vHPV or 9vHPV vaccine prevented 5,521,000 cases of anogenital warts among women and men. Around 23,520 and 21,400 diagnosed non-cervical cancers are prevented by catch-up vaccination among women and men, respectively. Compared with no vaccination, the ICER of 4vHPV vaccination was ¥975,364/QALY. Compared to 4vHPV, 9vHPV + Catch-up had an ICER of ¥1,534,493/QALY. CONCLUSIONS: A vaccination program with a 9-valent vaccine targeting 12 to 16 year-old girls together with a temporary catchup program will avert significant numbers of cases of HPV-related diseases among both men and women. Furthermore, such a program was the most cost effective among the vaccination strategies we considered, with an ICER well below a threshold of ¥5000,000/QALY.

RESUMO

INTRODUCTION: In Hong Kong (HK), a single-cohort vaccination program for 10-12-year-old girls with the 9-valent human papillomavirus (HPV) vaccine (9vHPV; types 6/11/16/18/31/33/45/52/58) has been launched. This study assessed the public health impact and cost-effectiveness of implementing routine 9vHPV vaccination (12-year-olds) with or without catch-up 9vHPV vaccination (13-18-year-olds) in HK. METHODS: The health impact and costs of implementing routine 9vHPV vaccination with or without catch-up vaccination over a 100-year time horizon were evaluated using a validated HPV-type transmission dynamic model adapted to the HK population; analyses were performed from a healthcare payer perspective. Routine vaccination (12-year-old girls) and catch-up vaccination (13-18 years) assumed vaccine coverage rates of 70% (base case) and 30%, respectively. The model also assumed herd immunity, lifelong vaccine protection, a discount rate of 3%, and a cost per dose of HK dollars (HKD) 858 [United States dollars (USD) 110] and HKD 1390 (USD 179) for the 2-valent HPV (2vHPV) and 9vHPV vaccines, respectively. HPV disease-related incidence and the incremental cost-effectiveness ratio (ICER) per quality-adjusted-life-year (QALY) were estimated. Cost-effectiveness was determined at a ceiling threshold of HK dollars (HKD) 382,046 (USD 49,142) or 1.0 times the gross domestic product per capita of HK. RESULTS: Compared with routine 9vHPV alone, routine plus catch-up 9vHPV is projected to reduce cervical cancer incidence by 3.4%. Routine plus catch-up 9vHPV will also reduce genital warts incident cases for males/females by 2.6%/5.4%. The incremental cost-effectiveness ratios were HKD 29,911 (USD 3847)/quality-adjusted life-year (QALY) for routine plus catch-up 9vHPV versus routine 9vHPV alone and HKD 25,524 (USD 3283)/QALY for routine 9vHPV alone versus screening only. Sensitivity analyses indicated that routine plus catch-up 9vHPV compared with routine 9vHPV alone remained cost-effective at coverage rates of 30% and 90%. CONCLUSIONS: This analysis predicts that the current HK vaccination strategy can be considered cost-effective and will provide maximum health benefit. These results support addition of the routine 9vHPV vaccine with or without catch-up 9vHPV vaccination to the regional vaccination program in HK.

RESUMO

BACKGROUND: Genital warts, caused by the human papillomavirus, are a common sexually transmitted disease. The warts can regress spontaneously or exhibit a persistent clinical course. Various therapeutic modalities are available, yet none is curative, and there may be recurrences. Retinoids are considered the mainstay of therapy in many dermatologic diseases. Data on their use for genital warts are limited. OBJECTIVE: To systematically review the published evidence on the efficacy and safety of retinoids for the treatment of genital warts. METHODS: A systematic review and meta-analysis of all publications evaluating topical or systemic retinoids for the treatment of genital warts was performed. The primary outcome was complete response (CR); the secondary outcomes were recurrence rate and adverse events. RESULTS: Six publications were evaluated, three randomized controlled trials and three prospective cohort studies, including a total of 141 patients with genital warts treated exclusively with retinoids (90% with isotretinoin). CR rates were 100% for systemic etretinate (3 out of 3 patients, 95% CI 28-81%) and 56% for isotretinoin (95% CI 28-81%; I2 = 84%). Topical etretinate did not induce CR. The most common side effect of topical agents was irritant contact dermatitis (36%) and that of systemic agents mucocutaneous disorders (80%). The relapse rate was 12% for oral isotretinoin and was unavailable for the other modalities. CONCLUSIONS: Current data suggest that unlike topical retinoids, systemic retinoids are an effective and safe treatment for genital warts. Further studies are required to determine their specific role and the most effective regimen for each derivative.

RESUMO

OBJECTIVES: To estimate the cost of six different techniques used to treat Genital Warts and the annual average cost of treating a typical GW patient in Peru. To estimate the annual economic burden diagnosing and treating GW in the Peruvian public healthcare system. METHODS: We developed a prevalence-based, cost-of-illness study from the provider's perspective, the healthcare facilities under the purview of Peruvian Ministry of Health. We used an activity-based costing approach. We conducted primary data collection in three regions in Peru and supplemented it with governmental data. Uncertainty of the costing estimates was assessed via Monte Carlo simulations. We estimated the average cost and associated confidence intervals for six treatment options - three topical and three surgical - and the overall cost per patient. RESULTS: The average treatment cost per patient was 59.9USD (95 %CI 45.5, 77.6). Given a population of 18.4 million adults between 18 and 60 years of age and a GW prevalence of 2.28 %, the annual cost of treating GW was 25.1 million USD (uncertainty interval 16.9, 36.6). CONCLUSIONS: This study provides the first quantification of the economic burden of treating genital warts in Peru and one of the few in Latin America. The costing data did not include other healthcare providers or out-of-pocket expenditures, and hence we present a conservative estimate of the COI of GW in Peru. Our findings bring attention to the financial burden of treating GW, a vaccine-preventable disease.

RESUMO

Anogenital warts (AGWs) are caused by human papilloma virus (HPV) and are transmitted by sexual route. The available options for the treatment of AGWs are cumbersome, require multiple sittings and are associated with recurrence. This is a case report of a male with condyloma acuminata who was treated successfully using injection vitamin D3. No recurrence was observed in a follow-up period of 6 months.

RESUMO

Human papillomavirus (HPV)-induced cutaneous disease is a common complaint for patients presenting for dermatology evaluation. Infection by HPV is the major etiologic factor in the development of cutaneous warts, epidermodysplasia verruciformis, and possibly a subset of cutaneous squamous cell carcinoma. Carcinoma of the genitourinary tract, most notably cervical carcinoma, is the most severe manifestation of infection with specific serotypes of HPV. For this reason, the HPV immunization (Gardasil) was developed in 2006 and upgraded in 2018 to a nonavalent formulation that includes serotypes 6, 11, 16, 18, 31, 33, 45, 52, 58. While immunization is highly effective at preventing infection with serotypes included in the formulation, it is less clear if the immunization can aid in managing active HPV infection. This review examines the available literature regarding the role of HPV immunization in managing common warts, genital warts, keratinocyte carcinoma, and epidermodysplasia verruciformis.

RESUMO

Cervical cancer is an important cause of death in women worldwide. About 99.7% of all cervical cancers have been related to human papillomavirus, especially types 16 and 18. Types 6 and 11 cause genital warts. We aimed to determine the prevalence of common HPV genotypes among women in the general population and women with cervical cancer. A total of 571 healthy women cytology specimens and 113 tissue samples of cervical cancer were investigated using HPV type-specific primers. HPV DNA was detected in 24% of healthy women: 3.3% were positive for high-risk HPV and 11.6% for low-risk HPV. HPV6 (9.3%) had the highest prevalence followed by HPV11 (2.3%), HPV16 (1.8%), HPV18 (1.2%), and 9.1% of samples were positive for unknown types. Among cervical cancer samples, HPV DNA was found in 78.8% including 43.4% HPV16, 8% HPV18, and 27.4% an unknown HPV type. HPV6 and HPV11 were not detected in any cervical cancer cases and 21.2% were negative for HPV. We found no association between HPV-16/18 and age in cervical cancer. The prevalence of HPV infection is relatively high in Iran without vaccination backgrounds. HPV DNA screening and vaccination programs can prevent cervical cancer and health problems caused by genital warts.

RESUMO

Human papillomaviruses (HPVs) can cause both benign and malignant tumors. To date, more than 200 HPV types have been discovered, of which 12 are currently classified as high risk for cervical cancer. HPV types that affect the anogenital tract are sexually transmitted. Since 2006, prophylactic HPV vaccines have been available and should be administered before first sexual contact.HPVs infect epithelial cells and are worldwide the most common sexually transmitted viruses. Apart from cervical cancer, HPVs cause other anogenital cancers such as vulvar, vaginal, and anal cancer but also oropharyngeal cancer (or head and neck cancers). HPV types 16 and 18 are also found at these sites. HPV types 6 and 11 are associated with genital warts; other HPV types can cause harmless skin warts.HPV vaccines are safe and highly effective, if they are administered before exposure to HPV. Systematic reviews and meta-analyses have shown that HPV vaccination effectively prevents HPV infection, but also precancerous lesions of the anogenital tract and genital warts. Recent vaccination data also demonstrate reductions in cervical cancer incidence.The uptake rates of HPV vaccination vary worldwide by program and acceptance. In comparison to other European countries, Germany has a low uptake rate. The Standing Committee on Vaccination (STIKO) recommends HPV vaccinations for all girls and boys ages 9 to 14 years in Germany. In 2018, only half of all 18-year-old girls in Germany were completely immunized against HPV.Organized vaccination programs, whether population-based or school-based, are necessary in order to increase vaccination uptake rates.
