Anal cancer in systemic lupus erythematosus patients is a neglected condition / Câncer anal em pacientes com lúpus eritematoso sistêmico é uma condição negligenciada

Patients with systemic lupus erythematosus have a higher incidence of neoplasms associated with human papillomavirus infections, such as those that affect the vulva, the vagina, and the cervix; however, little is known about the frequency of anal cancer among these patients. Although there are recommendations for screening for this cancer in immunosuppressed individuals, it is possible that this procedure is not strictly followed. We describe the case of a 47-year-old woman with systemic lupus erythematosus who was treated with immunosuppressants and developed advanced anal squamous cell carcinoma after adequate treatment and healing of a high-grade cervical squamous intraepithelial lesion. Five years after the completion of the anal cancer treatment, the patient presented with cystic hepatic lesions that were histopathologically confirmed to be metastatic squamous cell carcinoma. This report aimed to highlight the need for anal cancer screening in patients with lupus, particularly if there was a history of cervical cytopathological alterations. (AU)

Resumo Pacientes com lúpus eritematoso sistêmico apresentam maior incidência de neoplasias associadas a infecções por HPV, como aquelas que acometem a vulva, a vagina e o colo do útero, mas pouco se sabe sobre a frequência de câncer anal entre essas pacientes. Embora existam recomendações para o rastreamento desse câncer em indivíduos imunossuprimidos, é possível que esse procedimento não esteja sendo rigorosamente seguido. Descrevemos uma mulher de 47 anos com lúpus eritematoso sistêmico, tratada com imunossupressores, que desenvolveu um carcinoma escamocelular anal avançado após tratamento adequado e cicatrização de lesão intraepitelial escamosa cervical de alto grau. Cinco anos após o término do tratamento do câncer anal, a paciente apresentou lesões císticas hepáticas cujo resultado citopatológico confirmou ser carcinoma escamocelular metastático. O presente relato teve como objetivo chamar atenção para a necessidade do rastreamento do câncer anal em pacientes com lúpus, principalmente se houver história prévia de alterações citopatológicas cervicais.

Resumen Introducción: El cáncer de cérvix es el segundo en frecuencia y el tercero en mortalidad; la infección por el virus del papiloma humano (VPH) está asociada al riesgo de cáncer; sin embargo, no se conoce el riesgo acumulado a 1, 2, 3, 5 y 10 años. Objetivo: Determinar el riesgo de las pacientes VPH positivo con evaluación inicial citológica negativa para desarrollar lesión intraepitelial de alto grado a lo largo del tiempo. Método: Se realizó una revisión sistemática de artículos en inglés y español de los últimos 20 años, usando las bases de datos PubMed, Cochrane, LILACS, ProQuest y Embase. Se incluyeron ensayos clínicos aleatorizados en los que se determinaba el estado VPH y se realizaba seguimiento con citología cervicovaginal a 1, 2, 3, 5 y 10 años en mujeres de 20-64 años. Resultados: Se incluyeron siete ensayos clínicos aleatorizados, con un total de 98.521 mujeres, de ellas 8820 VPH positivo y 89.701 VPH negativo al ingreso, seguidas hasta por 10 años con citología cervicovaginal, encontrando que la infección por VPH es un factor de riesgo para desarrollar lesiones intraepiteliales de alto grado a 2, 5 y 10 años, con un riesgo relativo de 110.94 (79.41-154.97), 83.65 (55.22-126.73) y 29.71 (5.72-154.33), respectivamente. Conclusiones: La infección por VPH es un factor de riesgo importante para el desarrollo de lesiones intraepiteliales de alto grado a 2, 5 y 10 años.

Abstract Introduction: Cervical cancer is the second in frequency and the third in mortality, infection by the human papillomavirus (HPV) is associated with the risk of increased cancer; however, the cumulative risk of 1, 2, 3, 5 and 10 years is not known. Objective: To determine the risk of HPV-positive patients with negative initial cytological evaluation for developing high-grade intraepithelial lesion over time. Method: A systematic review of articles in English and Spanish in the last 20 years was carried out, using the PubMed, Cochrane, LILACS, ProQuest and Embase databases. Randomized clinical trials were included in which HPV was performed and subsequent follow-up with cervicovaginal cytology at 1, 2, 3, 5 and 10 years in women aged 20-64 years. Results: Seven randomized clinical trials were included, a total of 98,521 women, 8820 with positive HPV and 89701 negative on admission and followed up for up to 10 years with cervicovaginal cytology. Finding that HPV infection is a risk factor for developing high-grade intraepithelial lesion at 2, 5 and 10 years with a relative risk of 110.94 (79.41-154.97), 83.65 (55.22- 126.73) and 29.71 (5.72-154.33), respectively. Conclusions: HPV infection is an important risk factor for the development of high-grade intraepithelial lesion at 2, 5 and 10 years.

Distribution of HPV infection subtypes and HPV vaccination intention in Liaoyang / 公共卫生与预防医学

To analyze the distribution of HPV infection subtypes and HPV vaccination intention in Liaoyang area. Methods A total of 3 612 women in Liaoyang area who underwent HPV screening at the Department of Gynecology and Obstetrics of Liaoyang Central Hospital from November 2017 to December 2019 were enrolled in this study. The HPV infection in the population was analyzed, and the differences in HPV infection and multiple HPV infection of people at different ages were compared. The influencing factors of vaccination willingness were analyzed. Results There were 576 patients with HPV infection, and the infection rate was 15.95%. The difference in HPV infection at different ages was statistically significant (χ2=9.261, P=0.000), and the difference in multiple HPV infections at different ages was statistically significant (P<0.05). Among low-risk infections, HPV55, HPV61, and HPV81 were the main subtypes, and among high-risk infections, HPV16, HPV51, HPV66, and HPV53 were the main subtypes. In the multivariate analysis, the HPV vaccination intention of people with lower age and lower monthly family income, college students and students with non-medical majors was significantly lower. Conclusion The high-risk types of HPV in Liaoyang area are mainly HPV16, HPV51, HPV66, and HPV53. It is recommended to focus on the intervention of young people, people with low family monthly income, college students and students with a non-medical major to reduce the incidence of cervical cancer.

Vacunas terapéuticas del virus del papiloma humano: revisión de la evidencia actual / Therapeutic vaccines of the human papilloma virus: current evidence review

Resumen: OBJETIVO: Evaluar la inmunogenicidad de los distintos tipos de vacunas terapéuticas y de su efecto en las lesiones causadas por el virus del papiloma humano (VPH) después de su aplicación. Además, analizar los estudios de seguridad y las perspectivas de las vacunas terapéuticas contra el VPH. METODOLOGÍA: Estudio retrospectivo efectuado mediante la búsqueda bibliográfica sistemática en la base de datos PubMed, sin restricción de fecha de publicación. Criterio de inclusión: ensayos clínicos aleatorizados (metanálisis y revisiones sistemáticas). Criterios de exclusión: ensayos clínicos en fase preclínica del desarrollo y publicaciones en idiomas distintos al inglés o español. RESULTADOS: Se seleccionaron 30 artículos publicados entre 2000 y 2020. Entre ellos, 5 ensayos clínicos aleatorizados con vacunas terapéuticas que ya han finalizado o aún están en estudio. Las 25 publicaciones restantes incluyen: metanálisis y revisiones sistemáticas de aspectos seleccionados con objetivos primarios y secundarios. CONCLUSIONES: Las vacunas terapéuticas contra VPH se encuentran en fase experimental; hasta ahora se han conseguido resultados prometedores con algunas de ellas. Si bien existen distintos tipos de vacunas terapéuticas, los mejores resultados se han conseguido con las basadas en ADN. Las vacunas VGX-3100 y TS, en fase III, han demostrado diferencias significativas en el aclaramiento viral y la regresión de las lesiones de alto grado en pacientes vacunadas. Una vacuna terapéutica efectiva tendría una repercusión inmediata en la morbilidad y mortalidad por lesiones asociadas al virus.

Abstract: OBJECTIVE: To assess the immunogenicity of different types of therapeutic vaccines and their effect on human papillomavirus (HPV) lesions after application. In addition, to analyze the safety studies and prospects of therapeutic HPV vaccines. METHODOLOGY: Retrospective study based on a systematic literature search of the PubMed database, with no publication date restrictions. Inclusion criteria: randomized clinical trials (meta-analyses and systematic reviews). Exclusion criteria: clinical trials in the pre-clinical phase of development and publications in languages other than English or Spanish. RESULTS: 30 articles published between 2000 and 2020 were selected. Among them, 5 randomized clinical trials with therapeutic vaccines that have already been completed or are still under study. The remaining 25 publications include: meta-analyses and systematic reviews of selected aspects with primary and secondary objectives. CONCLUSIONS: Therapeutic HPV vaccines are in the experimental phase; so far promising results have been achieved with some of them. Although different types of therapeutic vaccines exist, the best results have been achieved with DNA-based vaccines. The VGX-3100 and TS vaccines, in phase III, have demonstrated significant differences in viral clearance and regression of high-grade lesions in vaccinated patients. An effective therapeutic vaccine would have an immediate impact on morbidity and mortality from virus-associated lesions.

Comparison between anal cytology, high-resolution anoscopy and HPV DNA genotyping by polymerase chain reaction in the post-treatment follow-up of condylomata acuminata / Comparação entre citologia anal, colposcopia anal e genotipagem do HPV por reação em cadeia da polimerase no seguimento pós-operatório de condiloma acuminado

ABSTRACT Aim: to evaluate the presence of subclinical HPV-induced anal lesions with anal cytology, High-Resolution Anoscopy (HRA) and HPV genotyping by polymerase chain reaction (PCR) in the follow-up of treated condylomata acuminata (CA). Methods: seventy-nine male patients were included. One month after anal CA eradication, the patients underwent brush samples collection for anal cytology and PCR, and HRA with biopsy of acetowhite lesions. These methods were compared within all patients and between groups, according to Human Immunodeficiency Virus (HIV) infection status: HIV-negative; HIV-positive with TCD4 count above and below 350 cells/mm3. Results: the most frequent HPV types were 6 and 16. HPV DNA was isolated in 92%. HIV infection was associated with a higher number of oncogenic HPV types (p=0.038). All patients with negative PCR had negative HRA and cytology. There were no differences in cytological, HRA or histopathological findings between groups. Conclusion: the association of the findings of cytopathology, HRA and genotyping of HPV refined the diagnosis of HPV-induced lesions. The degree of immunodeficiency was not associated with increase in remnant HPV-induced anal lesions.

RESUMO Objetivo: avaliar a presença de lesões anais subclínicas HPV-induzidas com citologia anal, colposcopia anal e genotipagem de HPV por reação em cadeia da polimerase (PCR) no seguimento de condilomas anais tratados. Método: foram incluídos 79 pacientes do sexo masculino. Após um mês da erradicação de lesões condilomatosas anais, os participantes voltaram em consulta para coleta de amostras com escova para citologia anal e PCR, e colposcopia anal com biópsia de lesões acetobrancas. Os métodos de detecção das lesões foram comparados entre os pacientes e entre grupos, de acordo com o status de infecção pelo vírus da imunodeficiência humana (HIV): HIV-negativo; HIV-positivo com TCD4 acima ou abaixo de 350 células/mm3. Resultados: os tipos de HPV mais frequentes foram 6 e 16. Infecção pelo HIV foi associada a maior número de tipos de HPV oncogênicos (p=0,038). Todos os pacientes com PCR negativo apresentaram colposcopia e citologia negativos. Não houve diferença nos achados citológico, colposcópico ou histopatológico entre grupos. Conclusão: a associação dos achados citopatológico, colposcópico e PCR melhorou a acurácia do diagnóstico de lesões anais HPV-induzidas. O grau de imunodeficiência não foi associado a maior frequência de lesões anais HPV-induzidas remanescentes.

Knowledge, attitude, and practice among staff associated with Human Papillomavirus vaccine of young children in Iran

@#Introduction: This study aimed to evaluate knowledge, attitudes, practice associated with Human Papillomavirus (HPV) Vaccine for Young Children among lecturers and health staffs of Shahid Beheshti University of Medical Sciences (SBMU). Method: This was a cross-sectional study with 220 adults from five different specialties, randomly selected. Data was collected using 45-item questionnaire on knowledge (12- item), attitude (18-item) and practice (15-item) (KAP) about HPV. The demographic questionnaire included information on age, gender, level of education, occupation, and marital status. Content validity was calculated by content validity ratio (CVR) and content validity index (CVI). Reliability was evaluated using test-retest and by Cronbach’s Alpha coefficient, internal consistency was calculated values >0.81 which considered as satisfactory. Results: The mean age of the studied population was 37.70± 8.07 (23-67) years. Of the 220 participants, 80 (36.4%) were males and 140 (63.6%) were females. In evaluating KAP in the men and women, the mean and standard deviation of knowledge were estimated at good level and one-way ANOVA analysis showed significant differences between women and men (p=0.019). There was no significant difference in men and women related to attitude (p=0.92) and practice (p=0.38). Conclusion: The KAP about HPV among participants was significantly higher at good levels compared to average levels. Women's knowledge was significantly higher than men. Attitude and practice could have been higher because there was consensus to the usage of vaccine among the specialists to prevent HPV.

Meta-analysis on effect of Kushen Gel on high-risk cervical HPV infection / 中草药

Objective: To systematically evaluate the effectiveness of Kushen Gel in the treatment of cervical high-risk human papillomavirus (HR-HPV) infection. Methods: The Cochrane Library, PubMed, Embase, Medline, Wanfang, VIP, CNKI, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on Kushen Gel in the treatment of the cervical high-risk HPV infection from their inception to December 2019. Two researchers screened the articles, extracted the data, assessed the risk of bias of the eligble studies independently, and performed Meta-analysis with RevMan 5.3. Results: A total of 583 cases were included in five RCTs. The Meta-analysis showed that HR-HPV negative rate [RR = 1.38, 95% CI(1.20, 1.58), P 0.05). Conclusion: The therapeutic effect of applying Kushen Gel can increase the rate of clearance of HPV, reduce HPV-DNA load, and reduce postoperative complication. There is no evidence that the use of Kushen Gel after LEEP can reduce the recurrence rate of CIN2/CIN3. Due to the limitation of the quantity and quality of the included studies, the results need to be further verified and updated by more high-quality RCTs.

El impacto de la prueba de VPH en los programas de tamizaje en América Latina: el caso de Argentina / The impact of the HPV test in screening programs in Latin America: The case of Argentina

Resumen: Objetivo: Evaluar el impacto de la prueba de VPH (prueba de VPH) en los problemas que históricamente afectaron al tamizaje de cáncer cervical en América Latina, tomando como caso al Proyecto Demostración para la Introducción de la prueba de VPH en Jujuy (PDJ), Argentina. Material y métodos: Se sintetizó la evidencia sobre los problemas del tamizaje cervical en la región. Se analizó el impacto en los problemas a partir de la introducción de la prueba de VPH. El impacto se clasificó en directo/indirecto y positivo/negativo. Resultados: El impacto directo-positivo se dio en los problemas de adherencia a la edad/frecuencia de tamizaje, laboratorios de citología, baja/moderada sensibilidad de la citología y baja cobertura. El impacto directo-negativo se vinculó con el triaje de autotoma y el envío/etiquetado de muestras. El impacto indirecto-positivo se relacionó con la reorganización programática realizada para introducir la prueba de VPH. Conclusiones: La prueba de VPH representa una ventana de oportunidad para el mejoramiento del tamizaje pero no resuelve los problemas programáticos.

Abstract: Objective: To assess the impact of HPV testing on longstanding problems faced by screening programs in Latin America, using the case of the Jujuy Demonstration Project (JDP) in Argentina. Materials and methods: The study measured the level of impact produced by the introduction of HPV-testing on problems faced by cytology programs by analyzing modifications on specific problems produced during the JDP. Impact was classified as direct/indirect, and positive/ negative. Results: Direct/positive impact was found in issues concerning age and screening frequency, cytology laboratories and screening sensitivity, and low coverage. Direct/negative impact was mainly related to the adherence to triage cytology by HPV+ women with self-collected-tests, and the delivery and labelling of samples. Indirect impact of HPV-Test was mostly positive, and related to the programmatic reorganization which was facilitated by the introduction of HPV testing. Conclusions: HPV testing provides an opportunity window for improving primary screening, but does not solve programmatic problems.

Queratosis seborreica en el fondo de saco de Douglas: reporte de un caso / Seborrheic keratoses in the recto-uterine pouch: Case report

Resumen ANTECEDENTES: Existen pocos reportes de neoplasias epiteliales con apariencia escamosa originadas en el cuello uterino o la vagina. Estas lesiones se clasifican, por su similitud morfológica, en lesiones similares a queratosis seborreica. Cuando ésta aparece en la mucosa de la vulva o vagina debe establecerse la diferenciación con lesiones intraepiteliales escamosas de bajo y alto grado. OBJETIVO: Describir un caso de queratosis seborreica en el saco de Douglas. CASO CLÍNICO: Paciente de 70 años, con pérdida involuntaria de orina con los esfuerzos; se le colocó una cinta suburetral para resolver este problema. Durante el procedimiento se detectó una lesión en la mucosa vaginal, a las seis del reloj, en el fondo del saco de Douglas, de 1.2 x 1 cm, color pardo y consistencia blanda. Durante el procedimiento se tomó una muestra para estudio histopatológico que se reportó como: epidermis con marcada hiperqueratosis, acantosis regular, ensanchamiento y anastomosis de las crestas con formación de perlas córneas, dermis con infiltrado inflamatorio crónico perivascular, negativo para malignidad. Se estableció el diagnóstico de queratosis seborreica hipertrófica, positiva para tinción de P16 que orientó a infección de virus del papiloma. El tratamiento fue: escisión con evolución satisfactoria y seguimiento. CONCLUSIONES: La queratosis seborreica en el fondo de saco de Douglas se reporta de manera excepcional, su comportamiento es benigno y casi siempre se asocia con tipos de virus del papiloma humano de bajo riesgo.

Abstract BACKGROUND: Thera are few repots of intraepithelial neoplasms with origins in the cervix or vagina with squamous appearance. This kind of lesions have been classified because of their morphologic similarities, in the category of "seborrheic keratoses like". When seborrheic keratoses appears in the vaginal or vulvar mucosa, it has to be differentiated from low and high grade intraepithelial squamous lesions. OBJECTIVE: To describe a case of seborrheic keratoses in the recto-uterine pouch. CLINICAL CASE: 70 years old patient, who underwent surgery for stress urinary incontinence with a sub-urethral sling. During the procedure, a lesion in the vaginal mucosa was detected, specifically in the recto-uterine pouch, of 1.2 x 1 cm length, with a light brown color and soft consistency. A specimen was taken from the lesion during the procedure for histopathological study, which reported: hyperkeratosis in the epidermis, regular acanthosis, thickening and anastomosis of the crests with formation of corneal pearls, dermis with inflammatory, chronic, perivascular infiltration, with no signs of malignancy. The diagnosis was hypertrophic seborrheic keratoses, positive for P16 stain which orients to HPV infection. The lesion was removed and the patient continued follow up with her primary care provider. CONCLUSIONS: Seborrheic keratoses in this location is uncommon, with few reports in literature. These lesions are usually benign and are associated to HPV of low risk.

Current Status of Human Papillomavirus Infection and Introduction of Vaccination to the National Immunization Program in Korea: an Overview

Human Papillomavirus (HPV) infection is the most common sexually transmitted infection and is associated with the development of cervical cancer. The purpose of this report is to provide the literature evidences on selecting the HPV vaccine for national immunization program (NIP) in Korea. To complete these tasks, we reviewed domestic and foreign literature on the current status of HPV infection, efficacy and effectiveness of HPV vaccine, safety of vaccine and cost effectiveness analysis of vaccination business. Given that the median age of first sexual intercourse is continuing to fall, this may have serious implications for HPV infection and cervical cancer incidence at the age of 20s. The World Health Organization recommends that the HPV vaccination should be included in the NIP being implemented in each country. Both the bivalent and quadrivalent vaccines have a 90% or greater preventive efficacy on cervical intraepithelial lesion 2–3 and cervical cancer by the HPV 16 or HPV 18. In the future, if HPV vaccination rate as part of NIP increases, it is expected that the incidence of HPV infection, genital warts, and cervical precancerous lesions will be decreased in the vaccination age group. Therefore, in order to increase the HPV vaccination rate at this point in Korea, social consensus and efforts such as the introduction and promotion of HPV vaccine to the NIP according to appropriate cost-effectiveness analysis are required.

Human papillomavirus infection and male reproductive health / 中华男科学杂志

Human papillomavirus (HPV) infection is one of the worldwide sexually transmitted diseases (STD), and the DNA of HPV can exist in the normal epithelium of reproductive organs of both men and women. Because the majority of HPV infections are asymptomatic, healthy HPV-carriers become the main source of the infection. Studies show that HPV infection in men is correlated with STD, infertility, tumor of reproductive organs, and infection in the sexual partners. Therefore, measures should be taken to reduce male HPV infection, including circumcision, fewer sexual partners, and condom use.

Prevalência de atipias citológicas e infecção pelo papilomavírus humano de alto risco em mulheres indígenas Panará, povo indígena do Brasil Central / Prevalence of cytological atypia and high-risk human papillomavirus infection in Panará indigenous women in Central Brazil / Prevalencia de atipias citológicas e infección por el virus del papiloma humano de alto riesgo en mujeres indígenas Panará, pueblo indígena de Brasil Central

O objetivo do estudo foi analisar a prevalência das atipias citológicas e infecção pelo papilomavírus humano em mulheres indígenas Panará no período de 2006 a 2007. Trata-se de estudo observacional transversal, com dados obtidos por coleta de amostras cérvico-vaginais para colpocitologia oncótica e captura híbrida, exame de colposcopia e biópsia. O trabalho incluiu 86 mulheres com idades de 12 anos ou mais, com história de vida sexual ativa ou pregressa. Os resultados mostraram que 10,7% das mulheres tinham atipias citológicas e que 28,6% estavam infectadas pelo HPV de alto risco oncogênico, principalmente entre as mais jovens (média = 25,6 anos). Dessas, 41,7% foram positivas para um ou mais dos tipos de HPV de alto risco dos genótipos 16, 18 ou 45, e a maioria, 58,3%, para outros tipos de HPV de alto risco. Conclui-se que é uma população especial, susceptível ao desenvolvimento das lesões precursoras do câncer do colo do útero e vulnerável às DST. Medidas preventivas como o rastreamento populacional sistemático para o câncer cervical e imunização contra o HPV são necessárias.

The aim of this study was to analyze the prevalence of cytological atypia and human papillomavirus infection in Panará indigenous women in 2006-2007. This was a cross-sectional observational study with data obtained from vaginal cervical samples for Pap smear and hybrid capture, colposcopy, and biopsy. The study included 86 females 12 years or older with a history of sexual activity. 10.7% of the women were diagnosed with cytological atypia and 28.6% were infected with high-risk HPV genotypes, which were more common among young women (mean = 25.6 years). Of these, 41.7% were positive for high-risk HPV genotypes 16 and/or 18 and/or 45, and the majority (58.3%) for other high-risk HPV genotypes. The study concludes that this group of indigenous women constitutes a special population, susceptible to develop precursor lesions for cervical cancer and vulnerable to STDs. Preventive measures are required, such as systematic cervical cancer screening and HPV immunization.

Oncogenic human papillomavirus detection in penile lichen sclerosus: An update.

Aims: Aim of this study was to better address a possible association of human papillomavirus (HPV) infection with penile lichen sclerosus (LS). Study Design: Paraffin-embedded penile biopsies obtained from adult patients with genital LS retrieved from institutional pathology files were evaluated. Place and Duration of Study: The study has been performed in the Dermatology Clinic of the University of Catania, Italy, spanning a 19-year period. Methodology: We previously demonstrated a high (17.4%) HPV detection rate in a study on 46 patients with genital LS. In this retrospective analysis we extended the analysis to a larger number of patients in order to strengthen these former data. HPV infection was assessed by polymerase chain reaction (PCR) in paraffin-embedded penile biopsies obtained from the glans or inner foreskin of 92 adult patients with penile LS and in brush cytology smears of penile healthy mucosa from an equal number of randomly selected control males matched for age. Statistical evaluation was performed using conditional logistic regression analysis. Results: PCR disclosed the presence of high risk HPV infection in 22.83% of LS patients (HPV 16:16 cases; HPV 18:1 case; HPV 31:1 case; HPV 45:2 cases; HPV 68:1 case) vs 15.21% of controls, (HPV 16:4 cases; HPV 31:1 case; HPV 53:1 case; HPV 56:1 case; HPV 68:1 case; HPV 70:1 case; HPV 81:5 cases). Statistical regression analysis confirmed that the rate of oncogenic HPV infection was higher among patients with genital LS than among healthy controls (χ2=8.26; P<.01; OR=3.59). Conclusion: These data suggest a possible pathogenetic interplay between LS and oncogenic HPV infection in the development of LS-associated penile cancer.

Clinical analysis of 15 cases with vaginal intraepithelial neoplasia and vaginal cancer after operations of cervical cancer or cervical intraepithelial neoplasia / 医学研究生学报

Objective Although the correlation between high risk human papilloma virus (hrHPV) infection and cervical cancer ( CC ) or cervical intraepithelial neoplasia ( CIN ) is well known , vaginal cancer ( VC ) or vaginal intraepithelial neoplasia ( VAIN) also caused by hrHPV has not received enough attention .This article aims to explore the clinical characteristics of VC or VAIN after operations of CC or CIN in order to provide evidence for the treatment of these diseases . Methods The clinical charac-teristics and treatment of 15 cases with VC or VAIN after operations of CC or CIN were reviewed from Jan 2010 to May 2013 in our hos-pital. Results The mean age was (53.6 ±10.82) years, ranged from 39 to 73 years.The duration from the first operation to devel-oped VAIN or VC was (25.07 ±18.31) months, ranged from 1 to 60 months.There are 4 cases developed VC, 4 cases VAINⅢand 2 cases VINⅡfrom 10 CC patients;and 3 cases developed VC , 2 cases VAINⅢfrom 5 CINⅢpatients.hrHPV test were positive in all 15 patients.Treatment in these series were performed including total vaginectomy in 8 patients (3 VC, 4 VAINⅢ and 1 VAINⅡpatients), pelvic lymphonectomy in 1;upper vaginectomy in 2 patients (1 VC, 1 VAINⅢ), radiation or chemo-radiation therapy in 3 (3 VC), interferon muscle injection combined with topical application of estrogen and acyclovir gel in 2 (1 VC, 1 VAINⅡ). Conclusion Careful follow-up after CC or CIN operations are very important because continued hrHPV infection may result VC and VAIN lesions.Vaginectomy may be the best therapy .Interferon muscle injection combined with topical application of estrogen and acyclovir gel are also alternatively therapy , especially for hard to operate patients . Radiation therapy seems to be not very adaptable for VAIN patients .

The impact of glucocorticoids and anti-cd20 therapy on cervical human papillomavirus infection risk in women with systemic lupus erythematosus

OBJECTIVE: To identify the prevalence and factors associated with cervical human papillomavirus infection in women with systemic lupus erythematosus METHODS: This cross-sectional study collected traditional and systemic lupus erythematosus-related disease risk factors, including conventional and biologic therapies. A gynecological evaluation and cervical cytology screen were performed. Human papillomavirus detection and genotyping were undertaken by PCR and linear array assay. RESULTS: A total of 148 patients were included, with a mean age and disease duration of 42.5±11.8 years and 9.7±5.3 years, respectively. The prevalence of squamous intraepithelial lesions was 6.8%. The prevalence of human papillomavirus infection was 29%, with human papillomavirus subtype 59 being the most frequent. Patients with human papillomavirus were younger than those without the infection (38.2±11.2 vs. 44.2±11.5 years, respectively; p = 0.05), and patients with the virus had higher daily prednisone doses (12.8±6.8 vs. 9.7±6.7 mg, respectively; p = 0.01) and cumulative glucocorticoid doses (14.2±9.8 vs. 9.7±7.3 g, respectively; p = 0.005) compared with patients without. Patients with human papillomavirus infection more frequently received rituximab than those without (20.9% vs. 8.5%, respectively; p = 0.03). In the multivariate analysis, only the cumulative glucocorticoid dose was associated with human papillomavirus infection. CONCLUSIONS: The cumulative glucocorticoid dose may increase the risk of human papillomavirus infection. Although rituximab administration was more frequent in patients with human papillomavirus infection, no association was found. Screening for human papillomavirus infection is recommended in women with systemic lupus erythematosus. .

Human papillomavirus risk factors for infection and genotype distribution in aboriginal women from Northern Argentina / Virus papiloma humano (hpv) en mujeres de la etnia Pilagá del nordeste argentino: Factores de riesgo de infección y distribución de tipos virales

The mortality rate for cervical cancer (CC) in Northern Argentina is three times higher than the average for the country (7.8 deaths/100 000 women). We determined the prevalence and genotype distribution of human papillomavirus (HPV) in 227 sexually active women of the native Pilagá community in Formosa, Argentina. We also conducted an HPV-16 variant analysis and studied several community factors that might play a role in viral entry and infection. Endo- and exocervical samples were tested for HPV DNA with MY09/11-PCR or with GP5+/6+-PCR. HPV was detected in 46.7% of the samples and 21 different types were found; the most frequent being HPV-16 (19.4%), -6 and -18 (5.3%), -58 (3.5%) and -31 and -33 (3.1%). In relation to HPV-16 variants, 68.2% were European and 31.8% Asian-American. Among the cofactors analyzed only disposal of human excreta to the open air (P=0.01) was significantly associated with HPV infection. Our prevalence estimates clearly show that Pilagá women are highly exposed to or infected with high risk HPV types and therefore are at a high risk of developing precancerous lesions and eventually CC at the population level.

La tasa de mortalidad por cáncer cervical (CC) en la región norte de la Argentina es tres veces más alta que la media del país (7.8 muertes/100 000 mujeres). En el presente trabajo se determinó la prevalencia de infección por virus papiloma humano (VPH) y la distribución y frecuencia de los genotipos en 227 mujeres sexualmente activas de la etnia aborigen Pilagá (Formosa, Argentina). También se realizó un análisis de las variantes intratípicas de VPH-16 presentes en la comunidad y se analizaron diversos factores socioculturales que podrían tener algún rol destacado en la transmisión de la infección viral. Se estudiaron muestras de células endo-exocervicales mediante PCR basadas en los cebadores MY09/11 y GP5+/6+ con posterior restricción enzimática y/o hibridación dot-blot. La infección por VPH fue detectada en el 46.7% de las mujeres analizadas. Fueron identificados 21 genotipos, de los cuales los más frecuentes fueron HPV-16 (19.4%), -6 y -18 (5.3%), -58 (3.5%) y -31 y -33 (3.1%). Respecto al HPV-16, se encontraron 68.2% de variantes europeas y 31.8% de asiático-americanas. Entre los cofactores analizados, solo la disposición de excretas al aire libre estuvo significativamente asociada con la infección por VPH (P = 0.01). Los datos obtenidos reflejan que la comunidad Pilagá está altamente expuesta a las infecciones por genotipos de alto riesgo de VPH, lo cual puede estar asociado a una alta incidencia de lesiones cervicales preneoplásicas y neoplásicas.

The value of high-resolution anoscopy in the diagnosis of anal cancer precursor lesions in hiv-positive patients / Anuscopia de alta resolução: valor diagnóstico em lesões precursoras de câncer anal em pacientes soropositivos

CONTEXT: Anal cancer, although a still rare disease, is being observed in ascending rates among some population segments known to be at risk for the development of the disease. Human papillomavirus (HPV) infection, immunodepression and anal intercourse are some factors associated with the development of the malignancy. Its similarities to cervical cancer have led to many studies aiming to establish guidelines for detecting and treating precursor lesions of anal cancer, with the goal of prevention. High-resolution anoscopy is routinely used for the diagnosis of anal cancer precursor lesions in many centers but the medical literature is still deficient concerning the role of this diagnostic modality. OBJECTIVES: To evaluate diagnostic validation and precision measures of high-resolution anoscopy in comparison to histopathological results of anal biopsies performed in HIV-positive patients treated at the Tropical Medicine Foundation of Amazonas, AM, Brazil. To observe any possible association between some risk factors for the development of anal cancer and the presence of anal squamous intraepithelial lesions. METHODS: A hundred and twenty-eight HIV-positive patients were submitted to anal canal cytological sampling for the detection of HPV infection by a PCR based method. High-resolution anoscopy was then performed after topical application of acetic acid 3 percent in the anal canal for 2 minutes. Eventual acetowhite lesions that were detected were recorded in respect to location, and classified by their tinctorial pattern, distribution aspect, relief, surface and vascular pattern. Biopsies of acetowhite lesions were performed under local anesthesia and the specimens sent to histopathological analysis. The patients were interviewed for the presence of anal cancer risk factors. RESULTS: The prevalences of anal HPV infection and of anal squamous intraepithelial lesions in the studied population were, respectively, 79 percent and 39.1 percent. High-resolution anoscopy showed sensibility of 90 percent, specificity of 19.23 percent, positive predictive value of 41.67 percent, negative predictive value of 75 percent, and a kappa coefficient of 0.076. From the analyzed lesions, high-grade squamous intraepithelial lesions was more frequently observed in association to dense (68 percent), flat (61 percent), smooth (61 percent), non-papillary (83 percent) and normal vascular pattern (70 percent) acetowhite lesions, while low-grade squamous intraepithelial lesions tended to be associated to dense (66 percent), flat-raised or raised (68 percent), granular (59 percent), non-papillary (62 percent) and normal vascular pattern (53 percent) acetowhite lesions. No statistical significance was observed as to the association of epidemiological characteristics and of most of the investigated anal cancer risk factors and presence of acetowhite lesions or anal squamous intraepithelial lesions. However, anal receptive sex and anal HPV infection were significantly associated to anal squamous intraepithelial lesions (P = 0.0493 and P = 0.006, respectively). CONCLUSION: High-resolution anoscopy demonstrated to be a sensitive, but not specific test for the detection of anal squamous intraepithelial lesions. Risk factors anal receptive sex and anal HPV infection were significantly associated to the presence of anal squamous intraepithelial lesions. Based on high-resolution anoscopy image data, acetowhite lesions relief and surface pattern were prone to distinguish between low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions.

CONTEXTO: O câncer anal, muito embora ainda seja uma doença rara, vem sendo observado com frequência ascendente em alguns grupos populacionais considerados sob risco para o desenvolvimento da doença. Infecção pelo vírus do papiloma humano (HPV), imunossupressão e o sexo anoreceptivo são alguns dos fatores associados ao desenvolvimento da neoplasia. Suas semelhanças com o câncer do colo do útero levaram muitos estudos voltados para o estabelecimento de regras para a detecção e tratamento de lesões precursoras do câncer anal, tudo com o objetivo de prevenir a doença. A anuscopia com magnificação de imagem é rotineiramente utilizada para o diagnóstico de lesões precursoras do câncer anal em muitos centros, mas a literatura médica ainda é escassa a respeito do papel a ser desempenhado por essa modalidade diagnóstica. OBJETIVOS: Avaliar as medidas de validação e precisão diagnósticas da anuscopia com magnificação de imagem em comparação com resultados histopatológicos de biopsias anais realizadas em pacientes HIV-positivos tratados na Fundação de Medicina Tropical do Amazonas, Manaus, AM, Brasil. Observar qualquer possível associação entre alguns fatores de risco para o desenvolvimento do câncer anal e a presença de lesões intraepiteliais escamosas anais. MÉTODOS: Cento e vinte e oito pacientes HIV-positivos foram submetidos a coleta de material celular anal para a realização da detecção da presença de HPV pela reação em cadeia da polimerase. Anuscopias com magnificação de imagem foram realizadas após a aplicação tópica de ácido acético a 3 por cento no canal anal por 2 minutos. As lesões acetobrancas eventualmente observadas foram registradas com respeito a sua localização e classificadas quanto ao seu padrão tintorial, aspecto de distribuição, relevo, características de sua superfície e vascularidade. Foram realizadas biopsias das lesões acetobrancas sob anestesia local e os espécimes foram remetidos para estudo histopatológico. Os pacientes foram entrevistados em relação à presença de fatores de risco para o câncer anal. RESULTADOS: As prevalências de infecção anal pelo HPV e de lesões intraepiteliais escamosas anais na amostra populacional estudada foram de 79 por cento e 39,1 por cento, respectivamente. A sensibilidade e a especificidade da anuscopia com magnificação de imagem foram, respectivamente, de 90 por cento e 19,23 por cento, enquanto que o valor preditivo positivo foi de 41,67 por cento, o valor preditivo negativo foi de 75 por cento e o coeficiente kappa de 0,076. Com respeito às lesões analisadas de alto grau foram mais frequentemente observadas em associação com lesões acetobrancas densas (68 por cento), planas (61 por cento), lisas (61 por cento), não-papilíferas (83 por cento) e com padrão vascular normal (70 por cento), enquanto que lesões de baixo-grau tenderam a se associar a lesões aetobrancas densas (66 por cento), plano-elevadas ou elevadas (68 por cento), granulares (59 por cento), não-papilíferas (62 por cento) e de padrão vascular normal (53 por cento). Não se observou significância estatística na associação entre características epidemiológicas e a maioria dos fatores de risco para o câncer anal e a presença de lesão acetobrancas ou de lesões intraepiteliais escamosas anais. Entretanto, o sexo anorreceptivo e a detecção de infecção anal por HPV, segundo a técnica da reação da cadeia de polimerase, associaram-se significantemente com lesões intraepiteliais escamosas anais (P = 0,0493 e P =0,006, respectivamente). CONCLUSÕES: A anuscopia com magnificação de imagem demonstrou ser um método diagnostico sensível, mas inespecífico para a detecção de lesões intraepiteliais escamosas anais. Os fatores de risco sexo anorreceptivo e infecção anal pelo HPV associaram-se significantemente à presença de lesões intraepiteliais escamosas anais. Com base nos achados da anuscopia com magnificação de imagem, o relevo e o aspecto morfológico da distribuição das lesões acetobrancas na superfície do canal anal tenderam a permitir a distinção entre lesões de baixo e alto grau.

Resposta imune celular ao papilomavírus humano em mulheres infectadas e não infectadas pelo vírus da imunodeficiência humana / Cellular immune response to human papillomavirus among women infected and noninfected with human immunodeficiency virus

Em razão da alta prevalência da infecção pelo papilomavírus humano (HPV) entre as mulheres, particularmente entre as jovens sexualmente ativas, podendo causar a neoplasia intraepitelial cervical (NIC) e o câncer cervical, é importante abordar os vários fatores associados a essa interação vírus-hospedeiro, e um dos fatores mais importantes é a resposta imune do hospedeiro. Esta, tanto sistêmica quanto local, tem papel crucial para determinar o curso da infecção. Nos casos de infecção persistente, há maior probabilidade de progressão para as NICs e/ou câncer invasor. Esta revisão tem como objetivo avaliar o papel da resposta imune local, em especial a resposta do tipo celular, no curso da infecção pelo HPV e na evolução ou regressão das lesões cervicais, na tentativa de melhor compreensão das diferentes formas de comportamento dessas lesões HPV induzidas, inclusive na associação com o vírus da imunodeficiência humana (HIV).

Given the high prevalence of human papillomavirus infection among women, particularly young sexually active women, and its role in the cause of cervical intraepithelial neoplasia and cervical cancer, it is important to address the several factors associated with this viral-host interaction. Among these factors, the most important is the host immune response. Both systemic and local response have crucial roles in determining the course of infection. In cases of persistent infection, there is a greater likelihood of progression to intraepithelial neoplasia and/or invasive cancer. The objective of this review is to evaluate the role of local immune response, particularly the response of cell type in the course of HPV infection as well as in the progression or regression of cervical lesions in order to better understand the behavior of different forms of HPV induced lesions, including its association with the human immunodeficiency virus.
