ABSTRACT

Objetivo: Identificar os fatores associados à infecção pelo papilomavírus humano em gestantes. Método: Revisão integrativa realizada nas seguintes bases de dados: BDENF, LILACS, MEDLINE e IBECS. Foram utilizados os seguintes descritores: "Papilomavirus Humano", "HPV", "Gravidez", "Infecções Sexualmente Transmissíveis" e "IST" (com respectivas traduções para o inglês). Resultados: Seis artigos compuseram a amostra final deste estudo. O design de pesquisa mais prevalente foi o estudo transversal (n: 03). Verificou-se que os fatores associados à infecção pelo HPV estavam relacionados a características sociodemográficas (menor idade, baixa escolaridade, estado civil solteira e consumo de álcool na gestação) e maternas (multiparidade). Conclusão: Verificou-se que alguns fatores podem estar associados à presença de infecção pelo HPV em gestantes, como características sociodemográficas e maternas. Faz-se necessário que os profissionais de saúde tenham um olhar mais atento a este público, afim de contribuir para disseminação da informação e consequente prevenção.(AU)


Objective: To identify factors associated with human papillomavirus infection in pregnant women. Method: Integrative review carried out in the following databases: BDENF, LILACS, MEDLINE and IBECS. The following descriptors were used: "Papilomavirus Humano", "HPV", "Gravidez", "Infecções Sexualmente Transmissíveis" and "IST" (with respective translations into English). Results: Six articles made up the final sample of this study. The most prevalent research design was the cross-sectional study (n: 03). It was found that the factors associated with HPV infection were related to sociodemographic (younger age, low education, single marital status and alcohol consumption during pregnancy) and maternal (multiparity) characteristics. Conclusion: It was found that some factors may be associated with the presence of HPV infection in pregnant women, such as sociodemographic and maternal characteristics. It is necessary that health professionals have a closer look at this public, in order to contribute to the dissemination of information and consequent prevention.(AU)

ABSTRACT

Introducción: el cáncer escamocelular (CEC) representa el 90-95% de todos los tipos de cáncer. En México, la frecuencia de CEC bucal (CECB) se ha incrementado y presenta una incidencia entre el 1 y el 5%. El CECB se asocia con sujetos en la quinta y séptima década de la vida, el sexo masculino, positivos a tabaquismo, alcoholismo, factores genéticos, inmunosupresión, infección por virus del papiloma humano (VPH) y estilos de vida poco saludables, entre otros. El objetivo de este trabajo fue presentar un caso clínico como ejemplo de las características emergentes en un paciente con CECB. Caso clínico: mujer de 38 años, con úlcera indurada, parcialmente adherida a planos profundos y dolorosa, asociada con un aumento de volumen, ubicada en vientre y borde lateral de lengua. Se realizó biopsia y con el diagnóstico histopatológico de carcinoma escamocelular invasor bien diferenciado, se procedió a determinar la presencia delVPH y resultó positivo a VPH 16. Se realizó tratamiento oncológico combinado (quirúrgico-radiación-quimioterapia), con buenos resultados para la paciente respecto a la estética y función. Conclusiones: se analizaron varios estudios que evalúan la presencia del VPH en lesiones de CECB, como un factor de riesgo que involucra con mayor frecuencia casos de pacientes jóvenes, la localización en lengua y antecedentes negativospara tabaquismo y alcoholismo frente a casos de CECB no asociados al VPH. Se requieren datos que contribuyan a dilucidar diversos aspectos aún desconocidos sobre la infección bucal por VPH y su relación con el CECB.


Background: Squamous cell cancer (SCC) represents 90-95% of all types of cancer. In Mexico, the frequency of oral SCC (OSCC) has increased, with an incidence between 1 and 5%. OSCC is associated with subjects in the 5 and 7th decade of life, males, positive for smoking, alcoholism, genetic factors, immunosuppression, human papillomavirus (HPV) infection, and unhealthy lifestyles, among others. Theobjectiveof thisworkwas to presenta clinical case as an example of the emerging characteristics in a patient with OSCC. Clinical case: 38-year-old female patient, with indurated ulcer, partially adhered to deep planes and painful, associated with an increase in volume, located on the belly and lateral edge of the tongue. A biopsy was performed and with the histopathological diagnosis of well differentiated invasive squamous cell carcinoma, the presence of HPV was determined, resulting positive for HPV-16. Combined cancer treatment was performed (surgical radiation-chemotherapy), with good results for the patient regarding aesthetics and function. Conclusions: We analyzed several studies evaluating the presence of HPV in lesions of OSCC, as a risk factor that involves more frequently cases of young patients, with location in tongue, and negative antecedents for smoking and alcoholism compared to cases of OSCC not associated with HPV. Data are required to help elucidate various still unknown aspects of oral HPV infection and its relationship with OSCC.

ABSTRACT

El cáncer de cuello uterino es la cuarta causa de mortalidad por cáncer en mujeres; 88 % de los casos provienen de países en vías de desarrollo debido al escaso acceso al tamizaje y tratamiento. Debido a esto, en los países de bajo desarrollo humano estrategias como la autotoma para la detección del virus del papiloma humano han adquirido gran importancia en la actualidad, aumentando hasta en un 45 % el tamizaje en estos países. La presente revisión bibliográfica tiene como objetivo determinar si existen diferencias entre técnica convencional para detección del virus del papiloma humano y la autotoma en países de mediano y bajo desarrollo humano, así como las ventajas y limitantes que esta presenta. Se realizó la búsqueda de la literatura mediante las bases de datos PubMed, Google Scholar y SciELO, empleando artículos originales, ensayos clínicos, de revisión, entre otros. Se demostró que la autotoma para la detección del virus del papiloma humano tiene una especificidad similar a la toma convencional por parte de personal médico y que incrementa el tamizaje, ya que es más aceptada que la muestra tomada por el clínico debido a que facilita el acceso y aborda las limitantes socioculturales percibidas por las usuarias


Cervical cancer is the fourth leading cause of cancer mortality in women; 88% of cases come from developing countries due to poor access to screening and treatment. Due to this, in countries with low human development, strategies such as self-testing for the detection of human papillomavirus have become very important today, increasing screening in these countries by up to 45%. The objective of this bibliographical review is to determine if there are differences between the conventional technique for detecting the human papillomavirus and self-testing in countries with medium and low human development, as well as the advantages and limitations that it presents. The literature search was carried out using the PubMed, Google Scholar and SciELO databases, using original articles, clinical trials, reviews, among others. It was shown that self-sampling for the detection of human papillomavirus has a similar specificity to conventional sampling by medical personnel and that it increases screening, since it is more accepted than the sample taken by the clinician because it facilitates access. and addresses the sociocultural limitations perceived by users

ABSTRACT

Resumen Objetivo: Comparar la expresión de mRNA y proteínas de SFRP1, PTPRN, CDO1, EDNRB, CDX2, EPB41L3 y HAND1 en pacientes con lesión intra-epitelial cervical de bajo y alto grado, con posterior progresión o regresión. Material y Método: Se realizó análisis de expresión de genes mediante RT-PCR y análisis de expresión de proteínas por inmunohistoquímica. El análisis estadís tico fue realizado con las pruebas: Wilcoxon, coeficiente de correlación de Spearman e índice de concordancia. Las muestras fueron pareadas en momento 1 y momento 2. Resultados: SFRP1 mostró tendencia de mayor expresión de mRNA en lesión intra-epitelial de bajo grado (momento 2) Vs. alto grado (momento 1). La expresión de proteínas por inmunohistoquímica de SFRP1 en casos de progresión (83,3 %) mostró disminución en su graduación (p = 0,0313*); los demás genes en estudio no tuvieron cambios estadísticamente significativos. Discusión: SFRP1 mostró comportamiento ajustado a resultados de estudios previos donde se encontró hipermetilado en lesiones intra-epiteliales de alto grado; su subexpresión por hipermetilación se reportó en otros canceres, proceso que colabora con su silenciamiento y transición epitelial-mesenquimatosa del cáncer de cuello uterino. Conclusiones. SFRP1 es potencial biomarcador en lesiones preneoplásicas del cuello uterino asociadas al virus de papiloma humano.


Abstract Objective. The aim of this work was to compare the expression of mRNA and proteins of SFRP1, PTPRN, CDO1, EDNRB, CDX2, EPB41L3 and HAND1 in patients with low and high grade cervical intraepithelial lesion, with subsequent progression or regression. Material and Methods: Gene expression analysis was conducted through RT-PCR and protein expression analysis was performed by immunohistochemistry. The statistics analysis were Wilcoxon test, Spearman's correlation coefficient and concordance index. The samples were paired during moment 1 (initial patient diag nosis) and moment 2 (follow-up histological diagnosis). Results: SFRP1 showed a trend of higher mRNA expression in low-grade intra-epithelial lesions (moment 2) Vs. high-grade (moment 1). The expression of proteins by immunohistochemistry of SFRP1 in progression cases (83.3%) showed a decrease in its graduation (p = 0.0313*); the other genes under study had no statistically significant. Discussion: SFRP1 showed a biological behavior adjusted to the results of previous studies where hypermethylation was found in high-grade intra-epithelial lesions; its subexpression by hypermethylation has been reported in other cancers, a process that collaborates with its silencing and epithelial-mesenchymal tran sition of cervical. Conclusions. SFRP1 is a potential biomarker in preneoplastic lesions of the cervix associated with human papillomavirus.

ABSTRACT

Introduction: the prevalence of cervical and anal human papillomavirus (HPV) infection in women infected with human immunodeficiency virus (HIV) is high. However, little is known about the differences in the susceptibility of these infections and related lesions. The aim of this study was to describe the association between the prevalence of cervical and anal HPV infection and HPV-related lesions in HIV-positive women. Methods: this study included 88 HIV-positive women attending an outpatient clinic in a university hospital. Ectocervical, endocervical, and anal samples were collected for colpocytology and anal cytology. A polymerase chain reaction-based technique was used to detect HPV deoxyribonucleic acid in endocervical and anal swab samples. Results: the cervical and anal HPV positivity rates were 35.21% and 78.8%, respectively. The presence of HPV-related lesions on colpocytology was associated with anal HPV positivity (P = 0.027). The ratio between cervical HPV infection and cervical HPV-related lesions was 2.5. The ratio between anal HPV infection and anal HPV-related lesions was 4.3. Overall, 30% had concomitant HPV DNA in the cervix and anus. Conclusion: there are differences in the susceptibility of infections and related lesions between the cervix and anus. Despite a higher incidence of anal HPV, the progression to HPV-related lesion does not occur via the same manner in the cervix and anus. Moreover, cervical HPV-related lesions in HIV-positive women may serve as a cue for anal preventive strategies, and further investigations in these women may be useful.


Introdução: as infecções cervicais e anais pelo papilomavírus humano (HPV) em mulheres infectadas com o vírus da imunodeficiência umana (HIV) são muito prevalentes. Entretanto, pouco se sabe sobre as diferenças na suscetibilidade entre essas infecções e as lesões HPV-relacionadas. Objetivo: descrever a associação entre as prevalências de infecção cervical e anal pelo HPV e lesões relacionadas em mulheres HIV-positivas. Metodologia: este estudo incluiu 88 mulheres HIV-positivas atendidas em ambulatório de hospital universitário. Amostras ectocervicais, endocervicais e anais foram coletadas para colpocitologia e citologia anal. Uma técnica baseada na reação em cadeia da polimerase foi usada para detectar o ácido desoxirribonucléico (DNA) do HPV em amostras de swabs endocervical e anal. Resultado: as taxas de positividade do HPV cervical e anal foram de 35,21% e 78,8%, respectivamente. As lesões relacionadas ao HPV na colpocitologia foram associadas à positividade anal para o HPV (P = 0,027). A proporção entre infecção cervical por HPV e lesões cervicais relacionadas foi de 2,5. A proporção entre a infecção anal por HPV e as lesões anais relacionadas foi de 4,3. 30% tinham DNA-HPV concomitante no colo do útero e ânus. Conclusão: existem diferenças na suscetibilidade de infecções e de lesões relacionadas entre o colo e o ânus. Apesar de maior incidência de HPV anal, a progressão para lesões relacionadas não ocorre da mesma forma no colo e no ânus. Além disso, lesões cervicais relacionadas ao HPV em mulheres HIV positivas podem servir como pista para estratégias preventivas anais. Investigações adicionais podem ser úteis.

ABSTRACT

Abstract In this nonsystematic review, the complementary diagnosis, treatment, prevention, and control of human papillomavirus are discussed. The histopathology is addressed regarding its indications, main findings and limitations, as a complementary diagnostic method largely used by dermatologists. Electron microscopy is briefly reviewed, along with its contribution to the accumulated knowledge on HPV, as well as the relevance of research in using this technology for future advances in diagnosis and treatment. Molecular information about the virus is continuously increasing, and the practical applications of HPV serology, molecular identification and genotyping are discussed. Vaccines are a valuable tool in primary HPV infection prevention and are now available in many countries; their composition, indications, and adverse effects are revisited. Local and systemic treatment options are reviewed and off-label prescriptions are discussed. Finally, health education focusing on HPV infection as a sexually transmitted infection of worldwide relevance and the many barriers to improve primary and secondary prevention are addressed.

ABSTRACT

Abstract Infection with human papilloma virus (HPV) is related to a great number of cutaneous and mucosal manifestations. The spectrum of HPV ranges from inapparent infections, through various clinical benign presentations including cutaneous and mucosal disease, to malignant and premalignant conditions. New HPV types are currently described in the literature; many of them are characterized as high-risk types due to their oncogenic potential. Knowledge regarding their epidemiology and pathogenesis is important to understand not only infection and disease processes, but also to formulate the clinical and laboratory basis for diagnosis, therapeutics, and prophylactic measures. This non-systematic review aims to discuss and to update those aspects, with an emphasis on relevant topics for dermatologists. HPV infection and related diseases in the Brazilian scenario are highlighted, including common dermatologic conditions seen at clinics as well as the condition of a public health problem as a sexually transmitted infection. The oncogenicity of the virus and the variety of clinical outcomes - especially in the immunocompromised individuals - are addressed.

ABSTRACT

INTRODUCCIÓN: Los problemas sanitarios en los pacientes que padecen cáncer cérvico-uterino influyen en la satisfacción personal y evitan una gran adherencia a la terapia médica, y además están relacionados con un número más notable de efectos secundarios y la estancia en la clínica de emergencia junto afecciones depresivas y problemas de ansiedad. OBJETIVO: Identificar la influencia del cáncer cérvico -uterino en las alteraciones en la salud mental de pacientes menores de 25 años en el Ecuador. METODOLOGÍA: La investigación fue de tipo cuantitativo, descriptivo, y de corte transversal. Se utilizaron encuestas de manera virtual dirigida a pacientes menores de 25 años que padecen de cáncer al cuello uterino en diversas Fundaciones que luchan contra el cáncer, contando con una muestra de 178 mujeres, estas se dividieron en 4 categorías: Salud mental, Estrés, Depresión y Total de escalas. RESULTADOS: El porcentaje que se obtuvo de manera general tuvo un rango variado, el 32,9% dio como resultado que la alteración que causa en la mujer es contundente, seguido del 30,6 que su afección en la salud mental es más baja. CONCLUSIÓN: Se concluye afirmando que el cáncer uterino es el segundo cáncer más prevalente en la mujer, el cual influye de manera progresiva en la salud mental, presentando reacciones negativas y percepciones, falta de control en las emociones, consecuentemente aquello debilita el sistema inmunológico previamente comprometido, generando alteraciones en el curso del tratamiento.


INTRODUCTION: Health problems in patients suffering from cervical-uterine cancer influence personal satisfaction and prevent a high adherence to medical therapy, and are also related to a more notable number of side effects and stay in the emergency clinic together depressive conditions and anxiety problems. OBJECTIVE: To identify the influence of cervical cancer -uterine in the alterations in the mental health of patients under 25 years in Ecuador. MATERIALS AND METHODS: The research was quantitative, descriptive, andcross-sectional. Surveys were used in a virtual way directed at patients under 25 years of age who suffer from cervical cancer in various Foundations that fight against cancer, with a sample of 178 women, these were divided into 4 categories: Mental health, Stress, Depression and Total stopovers. RESULTS: The percentage that was obtained in a general way had a varied range, 32.9% gave as a result that the alteration it causes in women is overwhelming, followed by 30.6 that their mental health condition is lower. CONCLUSION: It is concluded by stating that uterine cancer is the second most prevalent cancer in women, which progressively influences mental health, presenting negative reactions and perceptions, lack of control over emotions, consequently that weakens the previously compromised immune system, generating alterations in the course of treatment.

ABSTRACT

RESUMO: Objetivo: Estimar a cobertura da primeira e da segunda dose da vacina papilomavírus humano (HPV) no Brasil, conforme a microrregião, comparando-se as coortes de meninas com 14, 15 e 16 anos em 2017, e investigar a associação da heterogeneidade espacial na cobertura vacinal com variáveis sociodemográficas. Métodos: A informação sobre doses aplicadas nos anos de 2013 a 2017 por idade foi obtida do Programa Nacional de Imunizações. O número de meninas residentes com sete, oito e nove anos em 2010, em cada microrregião, é oriundo do censo brasileiro de 2010. Para a análise, a cobertura vacinal acumulada por microrregião (n = 558) foi categorizada em baixa (< 80%) e adequada (≥ 80%), e um modelo logístico com intercepto aleatório foi ajustado, tendo cobertura vacinal adequada como desfecho. O efeito aleatório (unidade da federação) foi incluído para captar a correlação entre microrregiões que pertencem ao mesmo estado. Resultados: O percentual de microrregiões que alcançou a cobertura vacinal adequada foi significativamente maior para a primeira dose (entre 91,8 e 159,2%), independentemente da coorte. Observou-se menor cobertura da segunda dose (entre 7 e 79,9%), com heterogeneidade associada ao grau de urbanização e à presença de domicílios com banheiro de uso próprio no município. O efeito aleatório mostrou forte poder explicativo, sugerindo importantes diferenças entre os estados brasileiros no alcance da cobertura vacinal. Conclusão: Apesar de a vacina HPV estar disponível no Programa de Imunização, os achados do presente estudo apontam para uma dificuldade do alcance da cobertura vacinal adequada.


ABSTRACT: Objective: To estimate the coverage of the first and second dose of the human papillomavirus (HPV) vaccine in Brazil according to microregion, comparing cohorts of girls aged 14, 15, and 16 years in 2017, and investigate the association between spatial heterogeneity in vaccination coverage and sociodemographic variables. Methods: Information about the doses administered from 2013 to 2017 by age was gathered from the National Immunization Program. The number of girls aged seven, eight, and nine years living in each microregion in 2010 was obtained from the 2010 Brazilian Census. For the analysis, the cumulated vaccination coverage per microregion (n = 558) was categorized as low (< 80%) and adequate (≥ 80%), and a random intercept logistic model was adjusted, with adequate vaccination coverage as the outcome. The random effect (federative unit) was included to identify the correlation between microregions that belong to the same state. Results: The percentage of microregions with adequate vaccination coverage was significantly higher in the first dose (between 91.8 and 159.2%), regardless of the cohort. The coverage of the second dose was lower (between 7 and 79.9%), with heterogeneity associated with the degree of urbanization and households with private bathrooms in the municipality. The random effect showed a strong explanatory power, suggesting important differences among Brazilian states as to the outreach of vaccination coverage. Conclusion: Although the HPV vaccine is available through the Immunization Program, the findings of the present study point to a difficulty in achieving adequate vaccination coverage.

ABSTRACT

BACKGROUND@#Cervical cancer remains a major public health issue for the Uyghur women and other women living mainly in rural areas of Xinjiang. This study aims to investigate the distribution of human papillomavirus (HPV) infection and cervical cancer in rural areas of Xinjiang, China.@*METHODS@#Cervical cancer screening was performed on rural women aged 35 to 64 years from Xinjiang, China in 2017 through gynecological examination, vaginal discharge smear microscopy, cytology, and HPV testing. If necessary, colposcopy and biopsy were performed on women with suspicious or abnormal screening results.@*RESULTS@#Of the 216,754 women screened, 15,518 received HPV testing. The HPV-positive rate was 6.75% (1047/15,518). Compared with the age 35-44 years group, the odds ratios (ORs) of HPV positivity in the age 45-54 years and 55-64 years groups were 1.18 (95% confidence interval [CI]: 1.02-1.37) and 1.84 (95% CI: 1.53-2.21), respectively. Compared with women with primary or lower education level, the ORs for HPV infection rates of women with high school and college education or above were 1.37 (95% CI: 1.09-1.72) and 1.62 (95% CI: 1.23-2.12), respectively. Uyghur women were less likely to have HPV infection than Han women, with an OR (95% CI) of 0.78 (0.61-0.99). The most prevalent HPV types among Xinjiang women were HPV 16 (24.00%), HPV 33 (12.70%), and HPV 52 (11.80%). The detection rate of cervical intraepithelial neoplasia (CIN)2+ was 0.14% and the early diagnosis rate of cervical cancer was 85.91%. The detection rates of vaginitis and cervicitis were 19.28% and 21.32%, respectively.@*CONCLUSIONS@#The HPV infection rate in Xinjiang is low, but the detection rate of cervical cancer and precancerous lesions is higher than the national average level. Cervical cancer is a prominent public health problem in Xinjiang, especially in southern Xinjiang.

ABSTRACT

ABSTRACT Background: Currently, persistent human papillomavirus (HPV) infection has been related in some geographic regions as a risk factor for esophageal squamous cell carcinoma. It results in the immunoexpression of the p16 protein, which has been used as marker of the oncogenic lineage by this etiological agent. Aim: To correlate epidemiological aspects of esophageal squamous cell carcinoma with the prevalence of HPV infection. Methods: Fifty-eight cases were analyzed and submitted to histopathological and immunohistochemical analysis by p16. Results: Of the 58 cases evaluated, 40 were men and 18 women, with a mean age of 63.2 years. p16 immunoexpression was positive in 46.55%. Conclusion: The prevalence of HPV infection is high in esophageal squamous cell carcinoma presenting in almost half of the cases (46.55%), without gender differentiation.


RESUMO Racional: Atualmente a infecção persistente pelo papilomavírus humano (HPV) tem sido relacionada em algumas regiões geográficas como fator de risco para o carcinoma epidermoide do esôfago. Ela resulta na imunoexpressão da proteína p16, que tem sido utilizada como marcadora da linhagem oncogênica por este agente etiológico. Objetivo: Correlacionar aspectos epidemiológicos do carcinoma epidermoide do esôfago com a prevalência de infecção pelo HPV. Métodos: Foram analisados 58 casos buscando-se perfil epidemiológico dos pacientes, com suas peças submetidas à análise histopatológica e imunoistoquímica pelo p16. Resultado: Dos 58 casos avaliados, 40 eram homens e 18 mulheres, com idade média de 63,2 anos. A imunoexpressão pelo p16 foi de 46,55%. Conclusão: A prevalência de infecção pelo HPV é alta no carcinoma epidermoide de esôfago apresentando-se em quase a metade dos casos (46,55%), sem diferenciação de idade quanto aos gêneros.

ABSTRACT

No hace muchos años la aproximación hacia las neoplasias malignas en seres humanos tenía un enfoque diagnóstico principalmente basado en los hallazgos morfológicos, y aunque teníamos conocimiento de la oncogénesis por virus desde hace casi medio siglo, este conocimiento no se había logrado integrar al diagnóstico, prevención y manejo oncológico [1]. En la década de los cincuenta, el entendimiento de la historia natural del cáncer de cuello uterino, con tiempos largos de evolución, permitió la implementación de protocolos de tamización, que hasta hace menos de una década, estaban basados en citologías cervicovaginales seriadas y regulares [2,3], sin mucho protagonismo en los algoritmos diagnósticos de la detección de variantes de alto riesgo del virus del papiloma humano (VPHAR) [4]. A pesar de que las pruebas moleculares se encuentran aprobadas para uso clínico desde aproximadamente el año 2001 [5], solo hasta el 2014 en países como Estados Unidos, se incorporó la detección de genotipos de VPH-AR como prueba de tamización principal, que determina la necesidad de estudios adicionales para la detección temprana del cáncer cervicouterino

ABSTRACT

Cada año, más de medio millón de mujeres en el mundo son diagnosticadas con cáncer cervical, usualmente asociado a la infección por virus del papiloma humano (VPH) de alto riesgo. Aunque la mayoría de las infecciones por VPH se resuelven dentro de un término menor de 2 años, algunos tipos virales, en particular el VPH16, pueden persistir por décadas y originar diferentes tipos de cáncer, siendo el cervical el más común. La historia natural de la infección por VPH de alto riesgo y el periodo prolongado en que ocurre su progresión, permite la prevención de la enfermedad. La infección por VPH de alto riesgo que evoluciona a cáncer incluye varios procesos como la integración del genoma viral, la división celular incontrolada, y la participación de cambios celulares y epigenéticos. La prueba de citología convencional que se viene practicando para la tamización hace más de 50 años continúa teniendo vigencia, especialmente en países de ingresos bajos y medios, pero está siendo reemplazada por otros métodos como las pruebas moleculares que detectan directamente la presencia del virus, con mayor efectividad como prueba de tamización. En 2014, el Ministerio de Salud y Protección Social de Colombia desarrolló una guía de práctica clínica para la detección y manejo de lesiones premalignas de cuello uterino, en la cual se recomienda la prueba de ADN-VPH para la tamización inicial en las mujeres mayores de 30 años. Hasta el momento se han encontrado resultados positivos con la implementación de la prueba, no obstante, se requieren estudios adicionales que confirmen estos hallazgos, dada su importancia en el control de la morbilidad y mortalidad asociadas a la infección


Each year, more than half a million women in the world are diagnosed with cervical cancer, usually associated with high-risk human papillomavirus (HPV) infection. Although most HPV infections resolve within 2 years, some viral types, particularly HPV16, can persist for decades and cause different types of cancer, being the cervical type the most common. The natural history of high-risk HPV infection and the prolonged period in which its progression occurs, allows for the prevention of the disease. High-risk HPV infection that progresses to cancer includes several processes such as viral genome integration, uncontrolled cell division, and the participation of cellular and epigenetic changes. The conventional Pap smear test that has been practiced as a screening method for more than 50 years continues to be used, especially in low- and middle-income countries, but it is being replaced by other methods such as molecular tests that directly detect the presence of the virus, with greater effectiveness as a screening test. In 2014, the Ministry of Health and Social Protection of Colombia developed a clinical practice guide for the detection and management of premalignant cervical lesions, in which the DNA-HPV test is recommended for initial screening in women over 30 years. So far, positive results have been found with the implementation of the test, however, additional studies are required to confirm these findings given its importance in controlling the morbidity and mortality associated with the infection

ABSTRACT

Utilidad clínica de la prueba La relación causal entre el desarrollo de cáncer de cérvix y la infección con genotipos de alto riesgo (AR) del virus del papiloma humano (VPH), ha llevado al desarrollo de estrategias para su detección y caracterización genotípica, como una medida de prevención de este tipo de cáncer. Dado que la presencia del VPH no puede ser determinada mediante los hallazgos clínicos de la paciente, como tampoco en los hallazgos morfológicos en la citología ni en la detección de anticuerpos específicos contra el VPH (pruebas serológicas), su detección y genotipificación recaen en el uso de pruebas moleculares, las cuales en su mayoría están dirigidas a la detección del ADN de los genotipos de alto riesgo, usando la técnica de reacción en cadena de la polimerasa (PCR) convencional y en tiempo real (RT-PCR) [1]. La técnica de PCR permite la amplificación de regiones específicas del ADN del VPH en los genes L1, E6 y E7, los cuales, por sus variaciones en la secuencia, permiten la genotipificación del virus [2,3]. Las pruebas de detección de ADN y/o genotipificación del VPH son consideradas herramientas de tamización en cáncer de cérvix, que detectan la infección causada por VPH. Su aplicación está enfocada en la clasificación de anormalidades citológicas, monitoreo de infecciones persistentes, seguimiento postratamiento de lesiones intraepiteliales de alto grado y vigilancia epidemiológica en salud pública [4-6]. La utilización de la citología y las pruebas de detección de ADN del VPH, aumenta la sensibilidad de la tamización para la detección de cáncer de cérvix y reduce de manera significativa el riesgo de sufrir lesiones cervicales premalignas por un periodo de 5 años [2,7]

ABSTRACT

O câncer de colo de útero é causado pela infecção persistente dos tipos oncogênicos do Papilomavírus Humano (HPV). O diagnóstico na fase inicial aumenta significativamente as chances de cura do câncer cervical. E, por isso, a detecção precoce do câncer é uma importante estratégia que possibilita maior chance de tratamento (INCA, 2021). De acordo com Instituto Nacional do Câncer (INCA, 2016) a colpocitologia oncótica cervical é um teste realizado para detectar alterações nas células do colo do útero que possam predizer a presença de lesões precursoras do câncer ou do próprio câncer. Este exame também é chamado de esfregaço cérvico vaginal, exame citopatológico do colo do útero, exame de Papanicolau ou simplesmente preventivo do colo de útero. A Secretaria de Estado da Saúde do Maranhão (SESMA), por meio da Secretária Adjunta da Política de Atenção Primária e Vigilância em Saúde (SAPAPVS), da Superintendência de Atenção Primária à Saúde (SAPS) e do Departamento de Atenção à Saúde da Mulher (DASMU), elaborou este guia com o intuito de orientar os profissionais que atuam na Atenção Primária, sobre as recomendações nacionais para o rastreamento do câncer de colo de útero, detecção precoce e os procedimentos técnicos para a coleta de colpocitologia oncótica.

ABSTRACT

El Cáncer de Cuello Uterino (CCU) es un problema de Salud pública a nivel mundial. Su indiscutible asociación con el Virus del papiloma humano (HPV) hace necesario su estudio. El objetivo de este trabajo, es conocer la prevalencia de los diferentes genotipos de HPV, en lesiones pre invasoras de alto grado de malignidad (HSIL) y/o cáncer de cuello uterino. Material y Métodos: Todas las Mujeres que fueron derivadas a pol de TGI del H Clínicas entre enero del 2011 y diciembre de 2012, por un PAP sospechoso de lesión y en las que se confirmó luego un HSIL o cáncer cervical fueron tipificadas. Se recabaron datos de edad, tipo de lesión y genotipificación. La extracción de ADN viral se realizó a partir de muestras cervico vaginales conservadas en medio de transporte comercial (Sacace) mediante el kit QIAamp DNA Mini Kit (QIAGEN). Se buscaron 14 genotipos de alto riesgo. Resultados: Se tipificaron 75 pacientes, 19 con CCU y 56 con HSIL. El HPV 16 fue el más prevalente en un 61,5 % para las infecciones únicas y en un casi 100 % para las múltiples y un 60% para el total de las lesiones, seguido en prevalencia por los HPV 31,33 y 45. El HPV 18 fue muy poco prevalente. Conclusiones: En esta muestra, la prevalencia del HPV 16 está acorde con las publicaciones nacionales siendo el más frecuente. El HPV 18 tiene muy baja prevalencia siendo 2 casos en 75, siempre en infecciones múltiples.


Cervical Cancer (CC) is a public health problem worldwide. Its indisputable association with the Human Papilloma Virus (HPV) makes its study necessary. The objective of this work is to know the prevalence of the different HPV genotypes, in pre-invasive high-grade malignant lesions (HSIL) and / or cervical cancer. Material and Methods: All women who were referred to Low genital tract service in the Hospital de Clinicas between January 2011 and December 2012, for a PAP suspected of injury and in which HSIL or cervical cancer was later confirmed were typified. Data on age, type of lesion and genotyping were collected. The viral DNA extraction was carried out from cervico-vaginal samples preserved in commercial transport medium (Sacace) using the QIAamp DNA Mini Kit (QIAGEN). 14 high-risk genotypes were searched. Results: 75 patients were typified, 19 with CCU and 56 with HSIL. HPV 16 was the most prevalent in 61.5% for single infections and almost 100% for multiple infections and 60% for all lesions, followed in prevalence by HPV 31,33 and 45. The HPV 18 was very rare. Conclusions: In this sample, the prevalence of HPV 16 is in accordance with national publications, being the most frequent. HPV 18 has a very low prevalence, being 2 cases in 75, always in multiple infections.

ABSTRACT

Resumen Introducción: aunque en la última década el concepto de biomedicalización ha sido relevante en América Latina para entender algunos procesos mediante los cuales la biomedicina participa en la constitución de sujetos y sus padecimientos, poco se ha explorado su relación con la conformación de la sexualidad. Desarrollo: el objetivo de este texto es analizar, desde una perspectiva sociológico-feminista, la biomedicalización del riesgo sexual al virus de inmunodeficiencia humana, mediante la profilaxis preexposición, y al virus del papiloma humano, mediante la aplicación de la vacuna de prevención en México, Colombia y Brasil. Primero, se presenta la noción de biomedicalización, sus usos teóricos en la sociología y los estudios de la ciencia, la tecnología y la biomedicina. Posteriormente, se abordan algunos textos que analizan algunas vicisitudes de la biomedicalización del riesgo sexual, mediante estas biotecnologías en los países mencionados. Finalmente, se problematizan algunas de las ventajas y retos teóricos del uso del concepto de biomedicalización en diversos contextos de América Latina y se señala cuál es su relevancia para comprender las relaciones y diferencias de género en la región. Conclusiones: en estos días, con el auge de la biomedicina y de las farmacéuticas transnacionales, se hace necesario analizar las implicaciones históricas, sociales y políticas de la biomedicalización de la sexualidad en contextos poscoloniales como el latinoamericano.


Abstract Introduction: In the last decade, the concept of "biomedicalization" has played a relevant role in Latin American Science, Technology, and Biomedicine (STS) studies amidst sociological and academic debates on the implications of biomedical interventions in the production of subjects and diseases. However, its relationship with sexuality has scarcely been evaluated. Development: This article aimed to analyze how sexual risk to avoid acquiring both human immunodeficiency virus through PrEP implementation and human papilloma virus through the preventive vaccine implementation in Mexico, Colombia, and Brazil has been thoroughly biomedicalized, from a sociological feminist perspective. First, the concept of biomedicalization and its theoretical uses in medical sociology and STS are briefly introduced. Then, few relevant texts are discussed that approach some aspects concerning the increase in biomedicalization of sexual risk within these biotechnologies in the three countries. Finally, we analyzed the advantages and challenges of introducing the concept of biomedicalization in the Latin American context and its relevance in terms of understanding sex-related relationships and differences. Conclusions: With the recent development of the biomedicine and transnational pharmaceutical industry, it is necessary to analyze the historical, social, and political implications of the biomedicalization of sexuality in the postcolonial contexts, such as those found in Latin America.


Resumo Introdução: ainda que na última década o conceito de biomedicalização tem sido relevante na América Latina para entender alguns processos mediante os quais a biomedicina participa na constituição de sujeitos e seus padecimentos, sua relação com a conformação da sexualidade tem sido pouco explorada. Desenvolvimento: o objetivo deste texto é analisar, desde uma perspectiva sociológico-feminista, a bio-medicalização do risco sexual ao vírus da imunodeficiência humana (VIH) mediante a Profilaxia pre-ex-posição (PrEP, por suas siglas em inglês), e ao vírus do papiloma humano (VPH) mediante a aplicação da vacuna de prevenção no México, na Colômbia, e no Brasil. Primeiro, se apresenta a noção de biomedi-calização, seus usos teóricos na sociologia e os STS (estudos da ciência, a tecnologia e a biomedicina, por suas siglas em inglês). Posteriormente se abordam alguns textos que analisam algumas variabilidades da biomedicalização do risco sexual, mediante estas biotecnologias nos países mencionados. Finalmente, se problematizam algumas das vantagens e desafios teóricos do uso do conceito de biomedicalização em diversos contextos da América Latina e se assinala qual é sua relevância para compreender as relações e diferenças de gênero na região. Conclusões: em nossos dias, com o auge da biomedicina e das farmacêuticas transacionais, se faz necessário analisar as implicações históricas, sociais e políticas da biomedicalização da sexualidade em contextos pós-coloniais, como o Latino-Americano.
