Human papillomavirus DNA testing with the urine sample is not yet available: the accuracy of two distinct kits

SUMMARY OBJECTIVE: The aim of this study was to assess the results and efficiency of two real-time polymerase chain reaction procedures for detecting human papillomavirus utilizing urine samples. METHODS: This study comprised 151 patients who had previously tested positive for human papillomavirus in their cervical samples. Two different commercial real-time polymerase chain reaction techniques were used for identification and genotyping human papillomavirus in urine specimens. The urine samples of 151 patients were evaluated via the Roche Cobas test, and the urine samples of 91 patients were also evaluated via the Qiagen test. RESULTS: The overall consistency of urine and cervical swab specimens for the identification of human papillomavirus in Roche Cobas and Qiagen tests were 44.8 and 44%, respectively. The rates of positive human papillomavirus results from urine samples were 57 and 70.3%, respectively. The overall concordance among Roche Cobas and Qiagen tests utilizing urine samples for human papillomavirus type 16/18 was 84.3% with a kappa value of 0.675, and for other high-risk-human papillomavirus, it was 75.60% with a kappa value of 0.535. Roche Cobas showed high concordance with Qiagen test. CONCLUSION: human papillomavirus positivity was not detected in all urine samples. It is still inappropriate to recommend the use of urine liquid biopsy for the accurate and reliable detection of human papillomavirus. Due to the lack of a standardized tool, the utilization of urine samples as a screening human papillomavirus test remains a challenge.

Prevalence of high-risk human papillomavirus genotypes among apparently healthy women with normal and abnormal cervical cytology in Kaduna State, Nigeria

Background: About 99.7% of cervical dysplasia and cancer cases are caused by persistent genital high-risk human papillomavirus (hrHPV) infection. Most HPV infections are subclinical and self-limiting but may persists in about 5 to 10% of infected women, resulting in pre-cancerous lesions that can progress to invasive cancer years later. This study is aimed at detecting hrHPV among apparently healthy women of reproductive age in Kaduna State, thus providing more information for effective control of HPV and cervical cancer in Nigeria. Methodology: Cervical smears were taken from 515 randomly selected apparently healthy women across selected secondary and tertiary facilities from 3 Local Government Areas (LGAs) in each Senatorial Zone of Kaduna State, Nigeria. Liquid-based cytology (LBC) technique was used to collect cervical smears and prepare smears for cytology study, while the remaining samples were stored at -80oC for molecular studies. HPV DNA were extracted from the samples and amplified by convectional PCR using specific hrHPV (HPV 16,18,31 and 45) primer sets and a broad spectrum MY09/11 and GP5+/6+ primers for a wider range of HPV genotypes. Data were analysed using the Statistical Package for Social Sciences (SPSS) version 23.0 and relationship between prevalence of hrHPV and socio-demographic factors such as age and marital status were determined using Chisquare or Fisher Exact test with p<0.05 considered statistically significant. Results: The prevalence of total HPV and hrHPV infections in the study population was 11.8% (61/515) and 9.3% (48/515) respectively. A total of 100 HPV genotypes were detected by PCR in the 61 positive smears, with 66 hrHPV types from 48 women, and 34 other HPV types from 13 women. The frequency of hrHPV genotypes detected was HPV 31 (5.8%, n=30), HPV 45 (4.1%, n=21), HPV 16 (1.7%, n=9), and HPV 18 (1.2%, n=6), with other HPV genotypes (6.6%, n=34). The frequency of cervical dysplasia was 6.4% (33/515), which was significantly associated with all HPV genotypes except HPV 16. Single HPV infection was seen in 31 (51.8%) women while multiple infections were seen in 30 (49.2%), with double infection in 21 (34.4%) and triple infections in 9 (14.7%). Conclusion: The prevalence of hrHPV infection was high among women in Kaduna State, Nigeria. DNA-based screening for hrHPV genotypes and production of new vaccine that will protect against the predominant hrHPV genotypes are thus recommended for the prevention of cervical cancer in Nigeria, Africa and beyond.

Research progress on diabetes and human papilloma virus infection and vaccination / 公共卫生与预防医学

Diabetes is a common chronic non-infectious disease. Diabetic patients not only suffer from metabolic disorders, but are also prone to immune deficiencies and are at a higher risk of being infected with human papillomavirus (HPV). Many studies at home and abroad have shown that the HPV infection rate of patients with diabetes is higher than that of non-diabetic patients. Patients with diabetes can benefit from HPV vaccination, and the tolerance is good. HPV vaccination is recommended for diabetic patients. This article reviews the research on diabetes, HPV infection, and HPV vaccine, which will provide references for HPV vaccination in diabetic patients.

Genotipificación del virus del papiloma humano en mujeres embarazadas VPH positivas / Genotyping of human papillomavirus in HPV-positive pregnant women

Resumen Antecedentes: Las embarazadas infectadas por el virus del papiloma humano presentan condiciones médicas que influyen en el curso de la enfermedad y pueden potenciar la posibilidad de transmisión vertical. Objetivo: Identificar los genotipos del virus del papiloma humano más frecuentes en mujeres embarazadas. Método: Estudio retrospectivo, observacional y descriptivo. Se emplearon muestras de raspado cervical. La extracción de material genético se hizo por la técnica de fenol-cloroformo y se amplificó empleando iniciadores universales MY09/MY11. Las muestras positivas se genotipificaron con un kit que detecta 37 genotipos diferentes. Resultados: Se identificaron 341 genotipos. Los más frecuentes fueron 16 (10.3%), 52 (8.8%) y 59 (8.6%). En el 75.9% la detección fue con un genotipo y en el 42.7% se detectaron infecciones múltiples. Conclusiones: Es sabido que la infección por virus del papiloma humano en mujeres embarazadas raramente evolucionará a lesiones invasivas. Se deberán considerar tanto las posibles complicaciones obstétricas a corto y largo plazo, así como las posibles repercusiones en la salud del recién nacido. La detección elevada del genotipo 16 sugiere un seguimiento estrecho para considerar un abordaje óptimo posterior a la gestación.

Abstract Background: Pregnant women infected with human papillomavirus have medical conditions that influence the course of the disease and can increase the possibility of vertical transmission. Objective: To identify the most common human papillomavirus genotypes in pregnant women. Method: Retrospective, observational and descriptive study. Cervical scraping samples were used. The extraction of genetic material was done by the phenol-chloroform technique and was amplified using universal primers MY09/MY11. Positive samples were genotyped with a kit that detects 37 different genotypes. Results: Three hundred forty-one genotypes were identified. The most frequent were 16 (10.3%), 52 (8.8%), and 59 (8.6%). In 75.9% the detection was with one genotype and in 42.7% multiple infections were detected. Conclusions: It is known that human papillomavirus infection in pregnant women will rarely evolve to invasive lesions. Both possible short- and long-term obstetric complications, as well as possible repercussions on the health of the newborn, should be considered. The high detection of genotype 16 suggests close follow-up to consider an optimal post-pregnancy approach.

Using High-Resolution Anoscopy to Detect Anal Dysplasia Due to Papillomavirus in Patients with Inflammatory Bowel Disease

Introduction: Anal squamous cell carcinoma is rare, but its incidence and mortality have been increasing globally; 90% of cases are related to human papillomavirus (HPV) infection(1,2). Patients with inflammatory bowel disease (IBD) have a higher risk of infection with this virus; an incidence of 5.5 per 100,000 patients has been identified in the IBD group compared to 1.8 in the non-IBD group(3). Materials and methods: A descriptive case series study was conducted with 21 patients with IBD and no perianal symptoms between January and July 2022 at the Institute of Coloproctology in Medellín. They underwent anal cytology, HPV genotyping, and high-resolution anoscopy after explanation and acceptance of the procedure. If lesions were found, ablative treatment was performed. Results: 23% of this cohort had low-grade squamous lesions, while 14.2% had high-grade lesions with dysplasia changes during anoscopy. Besides, 90.4% had positive HPV genotyping, of which 76.1% were high-grade. Conclusions: Our study suggests that this series of patients with IBD behaves as a high-risk group for developing premalignant lesions in association with HPV. High-resolution anoscopy is a cost-effective, painless, and affordable method that, in expert hands, may impact the diagnosis and management of premalignant lesions and decrease the incidence of anal cancer in patients with IBD.

Introducción: El carcinoma anal de células escamosas es raro, pero su incidencia y mortalidad han ido en aumento globalmente. El 90% de los casos están relacionados con la infección por el virus del papiloma humano (VPH)1,2 y los pacientes con enfermedad inflamatoria intestinal (EII) tienen un mayor riesgo de infección por este virus; se ha identificado una incidencia de 5,5 por 100.000 pacientes en el grupo de EII frente a 1,8 en el grupo sin EII3. Metodología: Se realizó un estudio descriptivo de serie de casos en el que se incluyó a 21 pacientes con EII, sin síntomas perianales, entre enero y julio de 2022 en el Instituto de Coloproctología de Medellín, a quienes se les realizó citología anal, genotipificación del VPH y anoscopia de alta resolución, previa explicación y aceptación del procedimiento. Si se encontraban lesiones, se realizaba tratamiento ablativo. Resultados: El 23% de esta cohorte tenía lesiones escamosas de bajo grado, mientras que el 14,2% presentaba lesiones de alto grado con cambios de displasia al momento de la anoscopia. El 90,4% tenían genotipificación positiva para VPH, de los cuales el 76,1% eran de alto grado. Conclusiones: Nuestro estudio sugiere que esta serie de pacientes con EII se comporta como un grupo de alto riesgo para desarrollar lesiones premalignas en asociación con el VPH. La anoscopia de alta resolución es un método rentable, indoloro y asequible que, en manos expertas, puede impactar el diagnóstico y manejo de lesiones premalignas y disminuir la incidencia de cáncer anal en pacientes con EII.

Percepción de usuarios de Facebook sobre la vacuna contra el VPH en publicaciones del Ministerio de Salud de Perú a partir de procesamiento de lenguaje natural

El objetivo de este estudio fue describir las percepciones de los usuarios de Facebook que realizaron comentarios, en las publicaciones realizadas desde la cuenta oficial del Ministerio de Salud de Perú (MINSA), referentes a la campaña de vacunación contra el VPH. Se analizaron 2748 comentarios en Python con procesamiento de lenguaje natural. Con este proceso se obtuvieron palabras claves que luego fueron interpretadas de manera manual. Se encontraron mayoritariamente cuatro tipos de discursos dentro de ellos: a) apoyo a la publicación sobre la vacuna contra el VPH; b) rechazo a la vacuna contra el VPH; c) Vacuna contra el VPH en niños; d) Dudas sobre la vacuna contra el VPH. En su mayoría, los usuarios que expresaron una postura de rechazo de esta vacuna se respaldaban de links a noticias donde se presentaba un evento supuestamente atribuido a la vacunación o inmunización pero que carecía de una fuente de información confiable y/o verificable.

The objective of this study was to describe the perceptions of Facebook users who commented on posts made by the official account of the Ministry of Health of Peru (MINSA) regarding the HPV vaccination campaign. We analyzed 2748 comments in Python with natural language processing. With this process we obtained keywords that were then interpreted manually. We found mostly four types of discourse, within them: a) support for the publications of the HPV vaccine; b) refusal of the HPV vaccine; c) HPV vaccine in children; d) doubts about the HPV vaccine. For the most part, users who expressed a position against this vaccine relied on links to online news stories that presented an event supposedly attributed to vaccination or immunization but lacked a reliable and/or verifiable source of information.

Comparación de protocolos de vacunación contra el virus del papiloma humano en Ecuador y América Latina / Comparation of vaccination protocols against the human papillomavirus in Ecuador and Latin America

INTRODUCCIÓN: El virus del papiloma humano (VPH), con más de 100 tipos, es de transmisión sexual. Varios países de América Latina han introducido las vacunas contra el VPH. Aunque América Latina es la región que más rápido avanzó en la vacunación contra el VPH, sus sistemas de seguimiento y vigilancia son aún deficientes. OBJETIVO: Comparar las diferentes estrategias de vacunación contra el VPH en Ecuador y América Latina. MÉTODO: Revisión bibliográfica, en la que se obtuvo información de documentos gubernamentales y artículos indexados en los últimos 5 años sobre las estrategias de vacunación contra el VPH en Ecuador y América Latina. RESULTADOS: La mayoría de los países de América Latina han logrado introducir la vacuna contra el VPH, excepto Venezuela, Martinica, Haití, Nicaragua y Cuba. CONCLUSIONES: Los protocolos de vacunación de Ecuador y América Latina necesitan mejorar sus sistemas de seguimiento y aumentar la expansión de datos de cobertura disponibles de manera consistente. Actualmente siguen existiendo desafíos para introducir las vacunas, lograr una alta cobertura y fortalecer el seguimiento, la evaluación y la notificación.

INTRODUCTION: The human papilloma virus (HPV), with more than 100 types, is a sexual transmission infection. Many Latin American countries have introduced the vaccines against the HPV. Although Latin América is the region which advanced faster against the HPV, its surveillance and follow-up systems are yet deficient. OBJECTIVE: To compare the different strategies to assume the vaccination against the HPV in Ecuador and Latin America. METHOD: Bibliographic review, in which information was obtained from government documents and articles indexed in the last five years on vaccination strategies against HPV in Ecuador and Latin America. RESULTS: Most Latin American countries have managed to introduce the vaccine against the HPV, except Venezuela, Martinica, Haiti, Nicaragua and Cuba. CONCLUSIONS: The vaccination protocols of Ecuador and Latin América need to improve their systems of follow-up and monitoring, and increase the expansion of available data in a consistent manner. Now, there are still existing challenges to introduce the vaccines, manage a high reach and fortify the follow-up, the evaluation, and the notification.

¿Está la virtud en el punto medio? La incertidumbre del CIN2 y el papel del VPH / Is virtue at the midpoint? The uncertainty of CIN2 and the role of HPV

Objetivo: La biopsia guiada por colposcopia (BGC) marca el manejo de la neoplasia intraepitelial cervical. El objetivo de este estudio fue evaluar la concordancia de los resultados entre la BGC y la escisión amplia de la zona de transformación (LLETZ, large loop excision of the transformation zone), y la utilidad del genotipado del virus del papiloma humano (VPH) para seleccionar a las pacientes con riesgo de lesión intraepitelial escamosa de alto grado/neoplasia intraepitelial cervical 3 (HSIL/CIN3). Método: Se compararon los resultados de la BGC y de la LLETZ, siendo esta última el método de referencia. Se evaluó la relación del genotipo del VPH con el diagnóstico final de HSIL/CIN3. Resultados: La precisión de la biopsia comparada con LLETZ fue del 61,4%. La tasa de concordancia fue del 64,4% para CIN1, del 31,4% para CIN2 y del 77,4% para CIN3. La tasa global de sobrediagnóstico fue del 18,68% y la de subdiagnóstico del 19,89%. En mujeres menores de 30 años, la concordancia fue del 62,79% (CIN1 65%, CIN2 39,58% y CIN3 73,08%), la tasa de sobrediagnóstico del 22,67% y la tasa de subdiagnóstico del 15,11%. La infección por VPH16 tuvo una odds ratio de 3,86 para el diagnóstico final de HSIL/CIN3+. Conclusiones: El diagnóstico de CIN2 por BGC parece insuficiente para seleccionar a las pacientes para tratamiento escisional, principalmente en mujeres jóvenes. El hallazgo de VPH16 es un factor de riesgo de HSIL/CIN3+ independientemente del resultado de la biopsia.

Objective: Colposcopy-guided biopsy (CGB) is a basic tool for the management of cervical intraepithelial neoplasia. The aim of this study is to evaluate the concordance of results between CGB and large loop excision of the transformation zone (LLETZ), and the usefulness of human papillomavirus (HPV) genotyping to select patients at risk of H-SIL/CIN3. Method: The results of colposcopy-guided biopsy and LLETZ were compared, with LLETZ being the gold standard. The relationship of HPV genotype to the final diagnosis of CIN3 was assessed. Results: The accuracy of CGB compared to LLETZ was 61.4%. The concordance rate was 64.4% for CIN1, 31.4% for CIN2 and 77.4% for CIN3. The overall overdiagnosis rate was 18.68% and underdiagnosis rate was 19.89%. In women under 30 years of age the concordance rate was 62.79% (CIN1 65%, CIN2 39.58% and CIN3 73.08%), and the rate of overdiagnosis and underdiagnosis was 22.67% and 15.11%, respectively. HPV16 infection had an odds ratio of 3.86 for the final diagnosis of CIN3+ and the result was significant regardless of the biopsy result. Conclusions: The CGB result as CIN2 is inaccurate and seems insufficient to select patients for excisional treatment, mainly in young women. HPV16 infection is a risk factor for CIN3+ regardless of the colposcopy-guided biopsy result.

Neoplasia cervical e infección por virus del papiloma humano como factores de riesgo para desarrollo de cáncer anal y lesiones precursoras / Cervical neoplasia and human papilloma virus infection as risk factors for the development of anal cancer and precursor lesions

RESUMEN La incidencia del cáncer anal ha presentado un incremento en los últimos 10 años, sobre todo en población considerada vulnerable. Las mujeres con antecedentes de infección por Virus del Papiloma Humano (VPH) en el tracto genital, tienen mayor riesgo de este tipo de cáncer. Se ha demostrado que, la infección con genotipos de VPH de alto riesgo (AR), en la región anogenital, desempeña un papel en la etiopatogenia de dicho cáncer. Se desconocen muchos aspectos de la historia natural de las lesiones anales, pero se considera que la zona de transición anal presenta un alto recambio celular, por lo que se ha planteado un mecanismo fisiopatológico de infección por VPH-AR y desarrollo de lesiones invasoras, similar al del cáncer cervical. El objetivo de este trabajo fue mostrar el estado actual sobre la información epidemiológica que vincula el riesgo de desarrollar cáncer anal en mujeres con lesiones precursoras de cáncer cervical asociadas a la infección por VPH. La relevancia de dicha información es proporcionar una base de recomendaciones para la detección oportuna de cáncer anal en mujeres consideradas de AR de padecerlo y, favorecer la realización de estudios prospectivos en la población.

ABSTRACT The incidence of anal cancer has increased in the last 10 years, especially in the population considered to be at risk. Women with a history of infection in the genital tract by Human Papillomavirus (HPV) have higher risk of developing this type of cancer. The presence of high-risk (HR) HPV genotypes in the anogenital region has been shown to play a role in the etiopathogenesis of anal cancer. Many aspects of the natural history of anal lesions are unknown, but the anal transition zone is considered to have a high cell replacement. This is why a pathophysiological mechanism of HR-HPV infection and development of invasive lesions similar to those of cervical cancer has been suggested. The aim of this work was to show the current status of the epidemiological information that links the risk of developing anal cancer in women with cervical cancer precursor lesions associated with HPV infection. The relevance of this information is to provide a basis of recommendations for the timely detection of anal cancer in women considered to be at HR of suffering it, and to encourage more prospective studies in this population.

A New Brazilian Device for Cervical Cancer Screening: Acceptability and Accuracy of Self-sampling / Um Novo Dispositivo Brasileiro para Diagnóstico de Câncer Cervical: Aceitabilidade e Precisão da Autoamostragem

Abstract Objective To evaluate the accuracy and patient acceptability toward self-sampling using a new device - SelfCervix® - for detecting HPV-DNA. Methods A total of 73 women aged 25-65 who underwent regular cervical cancer screening from March to October 2016 were included. Women performed self-sampling followed by a physician-sampling, and the samples were analyzed for HPV-DNA. After that, patients were surveyed about their acceptability of self-sampling. Results HPV-DNA detection rate of self-sampling presented high accuracy and was similar to physician-collection. Sixty-four (87.7%) patients answered the acceptability survey. Most patients (89%) considered the self-sampling comfortable, and 82.5% preferred self-sampling to physician-sampling. The reasons cited were time-saving and convenience. Fifty-one (79.7%) reported that they would recommend self-sampling. Conclusion Self-sampling using the new Brazilian device SelfCervix® is not inferior in HPV-DNA detection rate compared with physician-collection, and patients are supportive of the method. Therefore, it might be an option to reach under-screened populations in Brazil.

Resumo Objetivo Avaliar a acurácia e aceitabilidade da auto-coleta utilizando um novo coletor - SelfCervix® - para a detecção de DNA de HPV. Métodos Foram incluídas no estudo 73 mulheres com idade entre 25-65 anos que realizaram seu rastreamento regular do câncer de colo do útero entre Março e Outubro de 2016. Estas mulheres realizaram a auto-coleta, seguida de coleta profissional e as amostras foram analisadas paraa presença de DNA de HPV. Após, elas responderam um questionário sobre a experiência da auto-coleta. Resultados As taxas de detecção de DNA de HPV por auto-coleta foram altas e similares as da coleta profissional. Sessenta e quatro (87,7%) pacientes responderam o questionário de experiência. A maioria (89%) considerou a auto-coleta confortável, e 82,5% preferiram o método comparado a coleta profissional. As razões citadas foram economia de tempo e conveniência. Cinquenta e uma (79,7%) mulheres confirmaram que recomendariam a auto-coleta. Conclusão Auto-coleta utilizando o novo coletor desenvolvido no Brasil não é inferior na detecção de DNA de HPV quando comparada a coleta profissional, e apresenta uma boa aceitabilidade pelas mulheres. Desta maneira, pode ser uma opção para alcançar populações que não realizam o rastreamento padrão.

Human papillomavirus prevalence and frequency of sexually transmitted diseases in encarcered women by self-sampling approach

SUMMARY OBJECTIVE: This study aimed to assess the sociodemographic and clinical profile of women deprived of their liberty and to identify the prevalence of sexually transmitted diseases and human papillomavirus through self-sampling samples. METHODS: This is an epidemiological, cross-sectional, observational, and descriptive study of the prevalence and correlation of the diagnosis of human papillomavirus infection in 268 encarcered women in Amazonas submitted to self-sampling from June 2019 to September 2020 using the genotyping analysis. Patients with positive and inconclusive results were evaluated by commercialized PCR to detect pathogens causing sexually transmitted diseases. The sample size used was based on a convenience sample. RESULTS: In 268 women, human papillomavirus DNA was detected in 87 (32.5%) of them. Sexually transmitted diseases were detected in 30 (34.48%) of the 87 women with a positive or inconclusive result for human papillomavirus. Women with more than three pregnancies had a higher risk of human papillomavirus detection (p=0.004). CONCLUSION: The prevalence of human papillomavirus and other sexually transmitted diseases in encarcered women in Amazonas is 32.5 and 34.48%, respectively. Most women were single (60.4%) and reported having had more than 15 partners (90.8%).

Small cell neuroendocrine carcinoma with adenocarcinoma and high grade squamous intraepithelial neoplasia of the cervix

ABSTRACT Neuroendocrine neoplasm (NEN) of the cervix is a malignant tumor and is classified into low and intermediate-grade neuroendocrine tumor (NET), and high-grade small cell neuroendocrine carcinoma (SCNEC), and large cells neuroendocrine carcinoma (LCNEC). SCNEC of the cervix is an Infrequent tumor with an incidence of less than 1% of all gynecological malignancies. It is characterized by small to medium-sized tumor cells with scant cytoplasm and neuroendocrine differentiation. Most cases of SCNEC of the cervix manifest in pure forms, and only cases show coexisting, non-neuroendocrine component of HPV-associated adenocarcinoma or squamous cell carcinoma. In this report, reviewing the literature, we present one such unique case of SCNEC of the cervix with adenocarcinoma and high-grade squamous intraepithelial neoplasia.

Clarity of publications on HPV in Instagram profiles of official health agencies in Brazil

Abstract The study analyzed the clarity of publications on human papillomavirus (HPV) in the Instagram profiles of official Brazilian health agencies. An infodemiological study analyzed publications on HPV in the 81 Instagram profiles selected from the Health Ministry, States' Health Departments, and dental councils and associations. The following data were collected: classification of content, type of profiles, type of media, how the content was addressed, number of posts, frequency, likes, comments, viewings, and hashtags, and how the HPV vaccine was addressed. The clarity of the educational publications was assessed using the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis was performed with Spearman's correlation and the Mann-Whitney test (p < 0.05). A total of 504 publications on HPV were found. The average number of likes was 528.3 (SD = 2388.2) and the average BR-CDC-CCI score was 67.1 (SD = 14.1). The quality and clarity of the information was considered adequate (BR-CDC-CCI score ≥ 90) in 6.9% of the publications. A weak positive correlation was found between the number of likes and both the BR-CDC-CCI score (r = 0.195) and number of posts (r = 0.124). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score (72.9) compared to the other profiles analyzed (p = 0.01). Most publications concerned government actions, had low engagement, and written educational information was of low clarity and quality. However, the effort to reach the population was evident, with an increase in publications over the years.

Asociación entre la infección por virus del papiloma humano y el carcinoma de laringe en adultos de 35-75 años de edad en el instituto nacional del cáncer rosa emilia sánchez pérez de tavarez (incart), en el período agosto 2012 - enero 2019, santo domingo, república dominicana / Association between human papillomavirus infection and laryngeal carcinoma in adults between 35 and 75 years of age at the Rosa Emilia Sánchez Pérez de Tavarez National Cancer Institute (INCART), in the period August 2012 - January 2019, Santo Domingo, Dominican Republic

Introducción: el carcinoma de cabeza y cuello comprende un grupo de neoplasias que comparten un origen anatómico similar. Ocupan el sexto lugar mundial entre las neoplasias de todas las localizaciones, y el sitio afectado con mayor frecuencia es la cavidad oral. Ahora se reconoce el rol del virus del papiloma humano como factor independiente en el desarrollo de estas neoplasias. En los últimos 15 años se ha observado un incremento en la incidencia de carcinoma de células escamosas inducido por virus del papiloma humano (VPH). Materiales y métodos: este es un estudio observacional de tipo descriptivo transversal. Se realizó un análisis documental de los expedientes clínicos de los pacientes que cumplan con los criterios de inclusión. Resultados: en este estudio fue encontrada una prevalencia del 14 % del VPH en cánceres laríngeos. El tipo 16 del VPH fue el único identificado y descrito entre los expedientes clínicos de este estudio y, este último, con una prevalencia de un 20 %. Discusión: el VPH puede estar involucrado en el desarrollo de algunos cánceres de laringe y su rol puede ser más predominante en hombres mayores de 50 años.

Introduction: Head and neck carcinoma comprises a group of neoplasms with similar anatomical origins. They occupy the sixth place in the world among the neoplasias of all the locations, and the most affected site is the oral cavity. The role of the Human Papillomavirus as an independent factor in the development of these neoplasms is now recognized. In the last 15 years, an increase in the incidence of squamous cell carcinoma induced by Human Papillomavirus (HPV) has been observed. Methods: This is an observational study of transversal descriptive type. A documental analysis of the clinical files of the patients that meet the inclusion criteria was performed. Results: in this study, a 14 % prevalence of HPV in laryngeal cancers was found. Type 16 HPV was the only one identified and described in the clinical files of this study and the latter with a prevalence of 20 % Discussion: HPV may be involved in the development of some laryngeal cancers and its role may be more predominant in men older than 50 years.

HPV immunization in Brazil and proposals to increase adherence to vaccination campaigns / Imunização do HPV no Brasil e propostas para aumento da adesão à campanha de vacinação

ABSTRACT OBJECTIVES To identify the possible causes of low adherence to vaccination campaigns in Brazil, find and analyze campaigns regarding human papillomavirus (HPV) in Brazil and abroad, and apply quality tools to prepare proposals to increase vaccination coverage (VC) and prevent HPV in the country. METHOD This is a qualitative and deductive-hypothetical research. A narrative review of the literature (especially on the narratives and formats applied in vaccination campaigns in Brazil) was the technique used to develop our method. RESULTS Brazil had a 49.6% VC in 2019, unlike countries such as Australia (80.2% in 2017), Mexico (97.5% in 2019), and Peru (91% in 2019). This study found evidence of the use of social marketing strategies to engage communities as good practices in the vaccination campaigns of these countries. CONCLUSION With the retrieved information, three quality tools (Ishikawa diagram, Pareto graph, and 5W2H) classified and quantified the causes of low VC in Brazil and enabled proposals that can direct its Ministry of Health to take more effective strategies to achieve the HPV VC goal recommended by the WHO.

RESUMO OBJETIVOS Identificar as possíveis causas da baixa adesão à campanha de vacinação no Brasil, identificar e analisar as campanhas relacionadas ao papilomavírus humano (HPV) no Brasil e em outras regiões do mundo, e aplicar ferramentas de qualidade para elaboração de propostas para aumento da cobertura vacinal (CV) para prevenção do HPV no país. MÉTODO Pesquisa de natureza qualitativa e dedutiva-hipotética. A técnica utilizada para o desenvolvimento do método é a revisão narrativa da literatura, em particular estudando as narrativas e formatos aplicados nas campanhas de vacinação no Brasil. RESULTADOS Identificou-se que, em 2019, a CV no Brasil foi de 49,6%, diferentemente de países como Austrália (80,2% em 2017), México (97,5% em 2019) e Peru (91% em 2019). Evidências do uso de estratégias de marketing social para engajamento comunitário foram encontradas nas campanhas de vacinação utilizadas como boas práticas nesses países. CONCLUSÃO Com as informações encontradas foram aplicadas três ferramentas de qualidade (diagrama de Ishikawa, gráfico de Pareto e 5W2H) que classificaram e quantificaram as causas da baixa CV no Brasil e, com isso, viabilizaram propostas que podem direcionar o MS à tomada de estratégias mais eficazes para atingimento da meta de CV do HPV recomendada pela OMS.

HPV 18 variants in women with cervical cancer in Northeast Brazil

Abstract Background Human Papillomavirus (HPV) is the main etiological factor for the development of cervical cancer. HPV 18 is the second most frequent type, accounting for up to 65% of all cases. HPV intratypic variation may influence the potential for progression to invasive cancer. The aim of this study was to evaluate the prevalence of human papillomavirus 18 intratypic variants in cervical cancer samples from women in the state of Maranhão, Brazil. Methods The study included 118 women over 18 years of age with a diagnosis of cervical cancer. Tumor fragments were collected and subjected to DNA extraction and Polymerase Chain Reaction (PCR) for HPV detection using the PGMY09/11 and GP+5/6 primers. Positive samples were submitted to automated sequencing for viral genotyping. To determine the HPV 18 lineages, positive samples were submitted to PCR, using specific primers to amplify the LCR and E6 regions of HPV 18 virus. Results HPV was present in 88 women (73.3%). Of those, 48 (54%) were HPV 16, the most prevalent, followed by 12 (13.6%) HPV 18. Histologically, squamous cell carcinoma was predominant (79.1%). Among the HPV 18 variants identified, 10 (80%) belonged to lineage A, and sublineages A1, A2, A3, and A4. Two (29%) HPV 18 B variant was also detected, with the sublineages B1 and B2. In this study, the C variant was not found. There was no statistically significant association between the HPV 18 lineages found and sociodemographic and lifestyle variables (p > 0.05). Conclusions A higher frequency of HPV 16 and 18 were found in women with cervical cancer in the state of Maranhão, Brazil, with a high prevalence of the lineage A among women with HPV 18.

Impacto da imunização contra o papilomavírus humano na prevenção do câncer do colo do útero: uma revisão integrativa / Impact of immunization against human papillomavirus in the prevention of cervical cancer: an integrative review / Impacto de la inmunización contra el virus del papiloma humano en la prevención del cáncer de cuello uterino: una revisión integradora

Esta revisão integrativa teve como objetivo identificar na literatura a produção científica que estabeleça uma relação entre a vacinação contra o HPV e a prevenção do câncer do colo uterino. No período entre 24 de março e 28 de abril de 2023, foi realizada a busca bibliográfica seguindo os critérios de inclusão: artigos publicados nos últimos cinco anos, em português, inglês ou espanhol e Qualis CAPES mínimo B2. Para alcançar os objetivos dessa revisão, foram selecionados artigos a partir da análise dos títulos, dos resumos e da leitura integral, excluindo em cada etapa os que não se enquadravam nos critérios pré-estabelecidos. Após busca na base de dados, foram localizados um total de 973 artigos, 58 na PubMed e 915 na Biblioteca Virtual em Saúde. Destes, apenas oito artigos atenderam a todos os critérios e foram incluídos na presente revisão. Os trabalhos incluídos foram publicados, entre os anos de 2018 e 2022, em periódicos internacionais. Existem diversas evidências da relação entre a vacinação contra o HPV e a prevenção do câncer de colo uterino. Porém, a taxa de adesão à vacina ainda é muito baixa, por mais que esta tenha um papel fundamental na prevenção do câncer cervical, bem como na prevenção do câncer de pênis, anal e orofaríngeo e outras infecções pelo HPV.

This integrative review aimed to identify in the literature the scientific production that establishes a relationship between the immunization against HPV and the prevention of cervical cancer. In the period between 24 March and 28 April 2023 it was made a bibliography research following the inclusion criteria: articles published in the last five years, in Portuguese, English or Spanish, and Qualis CAPES minimum as B2. To reach this review goals, there were selected articles based on title analysis, summary and unabridged reading, excluding, in every stage, those that did not enter the preestablished criteria. After the research in the data base, there was found the total of 973 articles, 58 in PubMed and 915 in Virtual Health Library. Only eight articles met all criteria and were included in this review. All the articles included were published, between 2018 and 2022, in international periodicals. There is evidence of a link between HPV vaccination and the prevention to cervical cancer. However, the adhesion to the vaccine is still very low, even if it has a fundamental role in the prevention to cervical, penile, anal and oropharyngeal cancer, as well as in the prevention of other HPV infections.

High prevalence of HPV 18 and multiple infections with oncogenic HPV genotypes in women at risk of cervical cancer examined in Manaus, Brazil

Cervical cancer is a serious public health problem in Brazil, especially in Manaus (Amazonas), the city with the highest incidence rate of cervical cancer in the country. Persistent infection with oncogenic human papillomavirus (HPV) genotypes is the cause of disease development. The aim of this study was to investigate the prevalence of oncogenic genotypes in women at high risk for cervical precancer examined in two policlinics in Manaus. One hundred and two patients who underwent colposcopy took part in the research. The DNA samples obtained from the cervical epithelium were analyzed by PCR with type-specific primers for the detection of eight oncogenic genotypes, which were chosen based on previous studies. The presence of HPV virus was detected in all samples. The most prevalent oncogenic genotypes were 18 (47.1%) and 16 (45.1%). Interestingly, HPV 18 was considered uncommon in this region. In addition to these, genotypes 31 (19.6%), 58 (19.6%), 33 (18.6%), and 45 (15.7%) also had a relatively high frequency in this population. Fifty-six women (54.9%) had multiple infections with up to five oncogenic types. Also, the presence of genotypes other than 16 and 18 was observed in most samples (57.8%), which also deserves attention since they are not covered by currently available vaccines against HPV in Brazil. The high prevalence and multiple infections with several oncogenic HPV genotypes in association with precursor lesions for cervical cancer highlighted the need to improve strategies to prevent this disease in Amazonas.
