Principais motivos de descarte de córneas para transplante na Paraíba: por que o anti-HBc merece atenção?* / Main reasons for discarding corneas for transplant in Paraíba: why does anti-HBc deserve attention?*

RESUMO Objetivo: Identificar o perfil dos doadores de tecidos oculares humanos na área de atuação do Banco de Olhos da Paraíba, destacando o impacto da sorologia positiva para hepatite B no descarte dos tecidos para transplante. Métodos: O estudo é transversal e utilizou dados do Banco de Olhos da Paraíba entre janeiro de 2013 e dezembro de 2022. Dados sobre procedência, idade, sexo, causa do óbito, tempo entre óbito e enucleação, resultados sorológicos e motivo de descarte das córneas dos doadores foram coletados. Resultados: O maior motivo de descarte foi por sorologia positiva (56,5%), sendo positivadas as sorologias positivas para hepatite B e HBsAg em 11,1% e 4,75% dos pacientes, respectivamente. Conclusão: A sorologia positiva para hepatite B como um critério de descarte absoluto é responsável por grande parcela de descartes, apesar da pouca informação sobre suas repercussões e representação de infectividade nos receptores do transplante.

ABSTRACT Objective: To identify the profile of human ocular tissue donors in the area covered by the Eye Bank of Paraíba (PB), highlighting the impact of positive serology for hepatitis B (anti-HBc) in the disposal of tissues for transplantation. Methods: This is a cross-sectional that uses data from the Eye Bank of Paraíba (PB) between January 2013 and December 2022. Data on origin, age, sex, cause of death, time between death and enucleation, serological results, and reason for discarded donor corneas were collected. Results: The main reason for discarding was due to positive serology (56.5%), with positive anti-HBc and HBsAg serology in 11.1% and 4.75% of patients, respectively. Conclusion: Anti-HBc positive serology as an absolute disposal criterion is responsible for great part of disposals, despite little information about its repercussions and representation of infectivity in transplant recipients.

Trends and spatial distribution of hepatitis B in pregnant women in Brazil / Tendência e distribuição espacial da hepatite B em gestantes no Brasil

Abstract Objectives: to analyze the trend and spatial distribution of hepatitis B in pregnant women in Brazil. Methods: ecological study based on all notified cases of hepatitis B in pregnant women through the Information System for Notifiable Diseases - Sinan between 2009 and 2018. Hepatitis B virus (HBV) detection rates were calculated in all municipalities. Spatial analysis was performed using the Global Moran Index for global data and local indicators of spatial association (Lisa) for the 5,570 municipalities. For trend analysis by State, the Prais-Winsten generalized linear regression model was used. Results: 15,253 pregnant women with HBV were reported. High detection rates were observed in the municipalities of São Miguel da Boa Vista-SC (68.96/1000 live births (LB)), Araguaiana-MT (68.18/1000 LB), Reserva do Cabaçal-MT (80, 00/1,000 LB), São Geraldo da Piedade-MG (75/1000 LB), Porto Mauá-RS (111, 11/1000 LB), in the respective bienniums. Moran (I) (I=0.056) showed a positive spatial association. In Lisa, 78 municipalities were included in the high-high cluster, 51.28% in the South region and 48 in the low-low cluster with 72.91% in the Southeast. There was an increasing trend in Maranhão (p=0.004) and Pernambuco (p=0.007) and a decrease in Mato Grosso (p=0.012), Paraná (p=0.031) and Santa Catarina (p=0.008). Conclusion: the detection of hepatitis B in pregnant women was observed in most Brazilian municipalities, with an increasing trend in two states and a decrease in three others.

Scientific evidence on hepatitis B and SARS-CoV-2 infection: An integrative review / Evidências científicas sobre hepatite B e infecção por SARS-CoV-2: revisão integrativa / Evidencias científicas sobre la hepatitis B y la infección por SARS-CoV-2: revisión integradora

Background and Objective: Hepatitis B is an infectious disease caused by a virus from the hepadnaviridae family, with worldwide distribution, and represents a serious global health problem. The pathology may have been affected by the COVID-19 pandemic, caused by the SARS-CoV-2 virus, making it possible for serious outcomes to occur when overlapping viral types. This study sought to describe the levels of scientific evidence of research carried out on the topic, establishing a relationship between hepatitis B virus infection and SARS-CoV-2 infection. Content: integrative literature review, with searches performed in the databases of the Medical Literature Analysis and Retrieval System Online, and Scientific Electronic Library Online, with analysis centered on the description of the methodological design, and on the classification of the level of evidence. Conclusion: the scientific production on hepatitis B associated with SARS-CoV-2 infection corresponds mostly to studies with a low level of evidence. The selected publications presented limitations such as the occurrence of studies with a small number of samples, lack of subsidiary data of patients in treatment, and occurrence of non-randomized selection. The results suggest the need for further investigations for the purpose of technological improvement, identification of risk factors, therapeutic intervention, and advanced clinical investigation, in order to encourage evidence-based healthcare practices.(AU)

Serological and vaccine evaluation for hepatitis B among Community Health Workers / Avaliação sorológica e vacinal para hepatite B entre Agentes Comunitários de Saúde / Evaluación serológica y vacuna para la hepatitis B entre Agentes Comunitarios de Salud

Abstract Objective: to identify the vaccination and serological status against hepatitis B among community health workers; to vaccinate against hepatitis B virus and to evaluate the immune response of susceptible workers. Method: phase I, cross-sectional and descriptive study, among community health workers in a capital city of the Midwest region, through a self-administered questionnaire, checking of vaccination cards, and blood collection for testing of serological markers for hepatitis B. Phase II, cohort study carried out in vaccinated non-immune workers identified in phase I. They received one dose of vaccine (challenge dose) and serological testing. Results: a total of 109 workers participated in the study. Most had vaccination record (97; 89.0%) and vaccination completeness (75; 77.3%), while the isolated anti-HBs (Antibodies against hepatitis B virus) marker was detected in 78 (71.6%) workers. The prevalence of hepatitis B virus exposure was 8.2%. Of the ten non-immune vaccinated workers, after challenge dose, one remained susceptible. Conclusion: although most workers are vaccinated and show immunological response to hepatitis B, susceptibility after challenge dose was identified. Therefore, it is necessary to have a surveillance program of the vaccination situation and serological status for this virus, to promote these workers' safety.

Reporte de caso: vasculitis leucocitoclastica como forma de presentación de hepatitis b crónica / Case report: leukocytoclastic vasculitis as presenting manifestation of chronic hepatitis b virus infection

La vasculitis leucocitoclástica, también denominada angeitis cutánea leucocitoclástica, es la forma más común de vasculitis. Si bien la mayoría de los casos son idiopáticos, entre los agentes etiológicos que podemos nombrar se encuentran los agentes infecciosos, las enfermedades del tejido conectivos, las reacciones de hipersensibilidad a medicamentos y las neoplasias solidas o hematológicas. Si bien los procesos infecciosos son una causa conocida de vasculitis leucocitoclástica, la infección por virus de Virus de hepatitis B (VHB) es muy infrecuente. Presentamos una mujer de 47 años, sin antecedentes patológicos previos, que consultó por artralgias en rodillas y tobillos, mialgias en gemelos y rash purpúrico con leve prurito en ambos miembros inferiores, de un mes de evolución. La biopsia cutánea de las lesiones de miembros inferiores fue compatible con vasculitis leucocitoclástica. La serología de hepatitis B fue positiva por lo que inició tratamiento antiviral con Tenofovir y Prednisona con buena evolución de sus lesiones cutáneas

Leukocytoclastic vasculitis, also called leukocytoclastic cutaneous angiitis, is the most common form of vasculitis. Although most cases are idiopathic, etiologic agents include infectious agents, connective tissue diseases, drug hypersensitivity reactions, and solid or hematologic malignancies. Although infectious processes are a known cause of leukocytoclastic vasculitis, hepatitis B virus (HBV) infection is very rare. We present a 47-year-old woman, with no previous pathologic history, who consulted for arthralgias in the knees and ankles, myalgia's and purpuric rash with mild pruritus in both lower limbs, of one month evolution. Skin biopsy of lower extremity lesions was compatible with leukocytoclastic vasculitis. Hepatitis B serology was positive, so she started antiviral treatment with tenofovir and prednisone with good evolution of her skin lesions

Sobre la hepatitis aguda grave de etiología desconocida: la situación en México / About severe acute hepatitis of unknown etiology: the situation in Mexico

Introducción: en México, las hepatitis virales son de notificación epidemiológica obligatoria, pero no existe un sistema especial de vigilancia. La información disponible se limita a la distribución por edad y sexo. Ante la alerta de casos de hepatitis aguda grave de etiología desconocida, en la Unión Europea el Consejo Nacional de Vigilancia Epidemiológica (CONAVE) alertó al Sistema Nacional de Salud (SNS) para la atención y vigilancia de estos casos. Desarrollo: la hipótesis más convincente sobre la etiología está relacionada con una respuesta inmunitaria exacerbada que es mediada por superantígenos relacionados con la proteína espiga del SARS-CoV-2, activados por una infección por adenovirus que desencadena una respuesta de linfocitos T que provoca apoptosis de hepatocitos. Con base en la presentación clínica (niños menores de 16 años, con diarrea, dolor abdominal, ictericia, vómito e hipertransaminasemia) se han diseñado definiciones operacionales para su identificación y notificación al Sistema Nacional de Vigilancia Epidemiológica (SINAVE). Hasta junio del 2022, se han identificado 56 casos en México. Conclusiones: este brote de hepatitis representa un reto para el SINAVE. Es necesario incluir la identificación de adenovirus en el algoritmo diagnóstico de enfermedad respiratoria viral, implementar un sistema especial de vigilancia epidemiológica de hepatitis virales y sensibilizar a los profesionales sanitarios en el tema.

Introduction: In Mexico viral hepatitis requires mandatory epidemiological notification, but there is no special surveillance system. Available information is limited to distribution of cases by age and sex. Given the alert of cases of severe acute hepatitis of unknown etiology in the European Union, the National Council for Epidemiological Surveillance (Consejo Nacional de Vigilancia Epidemiológica) alerted the entire National Health System to care for and monitor these cases in Mexico. Development: The most convincing hypothesis is an exacerbated immune response mediated by superantigens related to the spike protein of SARS-CoV-2, activated by adenovirus infection that ends in a response of T lymphocytes that causes apoptosis of hepatocytes. Based on clinical presentation (children under 16 years of age, with diarrhoea, abdominal pain, jaundice, vomiting and increase in transaminases) the operational case definitions have been designed for their timely identification and notification to the National System of Epidemiological Surveillance (Sistema Nacional de Vigilancia Epidemiológica). Until June 2022, 56 cases have been identified in Mexico. Conclusions: This hepatitis outbreak represents a challenge for the National System of Epidemiological Surveillance. It is necessary to include the identification of adenovirus in the diagnostic algorithm for viral respiratory disease, to implement a special epidemiological surveillance system for viral hepatitis, and to sensitize health professionals on this subject.

Biomarcadores convencionales y emergentes en hepatitis B / Conventional and emerging biomarkers in hepatitis B

A nivel mundial, 300 millones de personas están infectadas por el virus de la hepatitis B (VHB). A pesar de que existe una vacuna que previene la infección y se dispone de tratamiento antiviral que suprime la replicación del virus, no hay cura aún. El principal problema que evita la recuperación total del paciente, incluso para aquel que recibe tratamiento, es la persistencia de dos formas del genoma viral en los hepatocitos: el ADN circular covalentemente cerrado (ADNccc), el cual se encuentra en forma de episoma y tiene la capacidad de replicarse, y las secuencias lineales subge-nómicas que se integran en el genoma humano, con potencial oncogénico. Hasta el momento se dispone de unos pocos biomarcadores para monitorear o predecir la progresión de la enfermedad y la respuesta al tratamiento. Estos biomarcadores se detectan durante la infección, y son la base para la monitorización de la enfermedad y hacer un diagnóstico de la fase clínica de la infección. Recientemente han surgido nuevos biomarcadores como el antígeno relacionado con el core del virus de la hepatitis B (HBcrAg) y la detección del ARN del VHB, que parecen correlacionarse con los niveles transcripcionales del ADNccc, además, durante el tratamiento parecen ayudar a predecir la respuesta y podrían identificar aquellos a quienes se les puede suspender la terapia sin riesgo de recaída. En esta revisión, se describe la utilidad de los principales biomarcadores convencionales en hepatitis B, y se abordan los dos biomarcadores emergentes más estudiados que prometen evaluar el curso de la infección, al igual que determinar la progresión de la enfermedad y la respuesta al tratamiento.

Globally, 300 million people are infected with hepatitis B virus (HBV). Although there is a vaccine that prevents infection and antiviral treatment that suppresses the replication of the virus, there is still no cure. The main problem that prevents the total recovery of the patient, even for those who recei-ve treatment, is the persistence of two forms of the viral genome in hepatocytes: covalently close circular DNA (cccDNA), which is in the form of an episome that has the ability to replicate, and linear subgenomic sequences that are integrated into the human genome, with oncogenic potential. Few biomarkers are currently available to monitor or predict disease progression and response to treatment. These biomarkers are detected during infection and are the basis for monitoring the di-sease and making a diagnosis of the clinical phase of the infection. New biomarkers have recently emerged, such as hepatitis B core-related antigen (HBcrAg) and HBV RNA detection, which seem to correlate with cccDNA transcriptional levels while during treatment seem to help predict response, and could identify those for whom therapy can be discontinued without risk of relapse. In this review, the usefulness of the main conventional biomarkers in hepatitis B is described, and the two most studied emerging biomarkers are mentioned, which promise to evaluate the course of the infection, as well as to determine disease progression and treatment response.

Análise da tendência espaço-temporal da hepatite B no estado do Pará, 2006 a 2018 / Analysis of the Spatio-temporal trend of hepatitis B in the state of Pará, 2006 to 2018

Objetivo: o presente estudo tem por objetivo realizar uma análise do perfil espaço-temporal da hepatite B no estado do Pará, entre os anos de 2006 e 2018. Métodos: trata-se de um trabalho epidemiológico, ecológico e descritivo, realizado no estado do Pará por meio de seus municípios e regiões de saúde. A base de dados foi levantada perante consulta ao Departamento de Informática do SUS (DATASUS). Foram calculadas as variações percentuais anuais (APC) nas taxas de incidência de hepatite B, mediante a modelagem pelo método Jointpoint, usando o ano calendário como variável de regressão. Resultados: no estado do Pará, foram notificados, no período do estudo, 3,228 casos, sendo, 48,3% em homens e 51,7% em mulheres, com média de 248,3 casos por ano (61,8 de desvio padrão). A taxa de incidência média entre os anos de 2006 a 2018, nos 144 municípios no estado do Pará, obteve uma grande variação de 0 a 21,54 casos por 100.000 mil habitantes. Conclusão: apesar da dispersão nas taxas de incidência, obteve-se uma tendência crescente da ocorrência de casos de hepatite B no período estudado, sugerindo a necessidade de medidas de saúde pública mais eficazes no combate ao HBV.

Objective: this study aims to analyze the spatiotemporal profile of hepatitis B in the State of Pará from 2006 to 2018. Methods: this is an ecological and descriptive epidemiological study carried out in the State of Pará through its municipalities and health regions. The database was collected from the consultation with the SUS Computer Department (DATASUS). The annual percentage changes (APC) in the hepatitis B incidence rates were calculated through modeling by the Jointpoint method, using the calendar year as a regressive variable. Results: in the state of Pará, 3,228 cases were reported, of which 48.3% were men and 51.7% were women, with an average of 248.3 cases per year (61.8 standard deviations). The average incidence rate between the years 2006 to 2018 in the 144 municipalities in the state of Pará obtained a wide variation from 0 to 21.54 cases per 100,000 inhabitants. Conclusions: despite the dispersion in incidence rates, there was an incre

Prevalencia de vacunación completa para la hepatitis B en el personal de salud de tres grandes hospitales generales del Paraguay / Prevalence of complete vaccination for hepatitis B in health personnel of three large general hospitals in Paraguay

Introducción: El personal de salud constituye un grupo de riesgo para la infección por el virus de las hepatitis B. Objetivos: Evaluar la frecuencia de vacunación contra Hepatitis B en profesionales médicos y de enfermería de tres grandes centros hospitalarios del Departamento Central de Paraguay. Materiales y métodos: Estudio cuantitativo, observacional, descriptivo, de corte transversal. Se aplicó un cuestionario al personal médico y de enfermería en estudio, elaborado según trabajos afines. Resultados: Fueron encuestadas 1097 personas, siendo médicos 412 (37.6%) yersonal de enfermería 685 (62.4%). Se encontró un nivel de vacunación completa del 48.2% sobre el total de encuestados, 49.5% de los varones presentaron esquema completo y 47.7% de las mujeres. Según la profesión, el personal de enfermería tiene mejor acatamiento con 51% de vacunación completa contra 47% del personal médico. En el Hospital Central del Instituto de Previsión Social, casi un 62% tenía esquema completo, el Hospital de Clínicas alcanzó 40.9% y solamente 36.6% de los encuestados del Hospital Nacional de Itauguá tenían todas las dosis de vacuna anti-Hepatitis B. Para riesgo biológico bajo, el nivel de vacunación completa fue del 36.0%, alcanzó el 36.8% para riesgo moderado y 57.3% para los de alto riesgo de exposición. Conclusión: Ante la baja prevalencia de vacunación completa contra Hepatitis B en el personal de salud, esta debe mejorarse considerando el riesgo biológico de exposición. El equipo de control de infecciones y el Departamento de salud laboral deben llevar un registro de vacunación del personal y tener un plan de inmunizaciones obligatorio.

Introduction: Health care personnel constitute a risk group for hepatitis B virus infection. Objectives: To evaluate the frequency of vaccination against Hepatitis B in medical and nursing professionals of three large hospital centers in the Central Department of Paraguay. Materials and methods: Quantitative, observational, descriptive, cross-sectional, cross-sectional study. A questionnaire was administered to medical and nursing personnel included in the study, based on related studies. Results: A total of 1097 people were surveyed, 412 (37.6%) were physicians and 685 (62.4%) were nurses. In general, a complete vaccination level of 48.2% of the total respondents was reached, 49.5% of men had a complete vaccination schedule and 47.7% of women. According to profession, the nursing staff had a better compliance with complete vaccination with 51% versus 47% of the medical staff. In the Hospital Central del Instituto de Previsión Social almost 62% had a complete schedule, the Hospital de Clínicas reached 40.9% and only 36.6% of the respondents of the Hospital Nacional de Itauguá had all the doses of anti-Hepatitis B vaccine. For low biological risk, the level of complete vaccination was 36.0%, reaching 36.8% for moderate risk and 57.3% for those at high risk of exposure. Conclusion: The level of complete vaccination against Hepatitis B in health personnel was low and should be improved, taking into account the biological risk of exposure. The infection control team and the occupational health department should keep a record of staff vaccination and have a mandatory immunization plan for it.

Luego del llamado realizado por la Asamblea Mundial de la Salud en el 2014, para que los países implementen medidas que garanticen y fortalezcan la vigilancia, la prevención, el acceso al tratamiento y el control de las hepatitis virales en todos los países, nos preguntamos ¿Qué avances hemos tenido? En el 2016, con la finalidad de fortalecer la atención del recién nacido y seguimiento del niño expuesto a madres con hepatitis B en el Perú, se aprobó el documento técnico "Plan Nacional para la Eliminación de la Transmisión Materno Infantil del VIH, Sífilis, y Hepatitis B, en el Perú 2017-2021", en la cual se establece como objetivos acciones para reducir la transmisión infantil de hepatitis B a un 5%. En referido documento se identifican limitantes como: el bajo porcentaje de niñas y niños expuestos tamizados, pérdida del seguimiento de gestantes y de niños y niñas expuestos, y la débil coordinación entre los servicios de la salud.

Retorno social de la inversión tras eliminar la transmisión vertical de chagas, VIH/sida, HB y sífilis: caso de un municipio de la Provincia de Buenos Aires / Social Return on the investment of the elimination of the vertical transmission of Chagas, HIV / AIDS, HB and Syphilis: Case of a Municipality of the Province of Buenos Aires

Resumen Introducción: se busca cuantificar los retornos de la inversión asociados a una intervención en el sistema público de salud de un municipio de la Provincia de Buenos Aires, Argentina, consistente en el fortalecimiento de la estrategia denominada Eliminación de la Transmisión Maternoinfantil de la Infección por VIH, Sífilis, enfermedad de Chagas Congénita e Infección Perinatal por Hepatitis B (ETMI-PLUS). Metodología: el estudio (cuantitativo) se basa en la metodología de Retorno Social de la Inversión (RSI). Se establecieron definiciones ad-hoc para la medición de los retornos sobre la base de los datos disponibles provenientes de diversas fuentes: información primaria de la Secretaría de Salud del MAB; tasas de transmisión congénita de cada enfermedad notificados al Sistema Nacional de Vigilancia de Salud; presupuestos detallados de los recursos asignados al proyecto por parte de la Fundación Mundo Sano y costos de tratamientos e insumos de nomencladores oficiales. Resultados: por cada peso invertido para reforzar la ETMI-PLUS en el MAB, se obtuvo un retorno de casi 4 pesos, gracias a las mejoras en la eliminación vertical de las cuatro enfermedades y al descenso de las complicaciones cardiacas en las mujeres embarazadas diagnosticadas con chagas y tratadas oportunamente. Conclusiones: estos resultados sugieren la existencia de una relación retorno-inversión favorable, analizada bajo una perspectiva conservadora, ya que, se incluyen exclusivamente los ahorros para el sistema de salud y se excluyen otras dimensiones de los retornos vinculadas con las mejoras en los resultados alcanzados.

Abstract Introduction: we seek to quantify the returns on investment associated with an intervention in the public health system of a Municipality of the Province of Buenos Aires, Argentina. This intervention consists of strengthening the strategy for the Elimination of Mother-to-Child Transmission of HIV Infection, Syphilis, Congenital Chagas Disease and Perinatal Hepatitis B Infection, a strategy called ETMI-PLUS. Methodology: the study (quantitative) is based on the Social Return on Investment (RSI) methodology. Ad-hoc definitions are established for the measurement of returns based on the information available from various sources: primary information from the Ministry of Health of the MAB; rates of congenital transmission of each disease reported to the National Health Surveillance System; detailed budgets of the resources assigned to the project by Fundación Mundo Sano and costs of treatments and supplies from official nomenclators. Results: for each argentinean peso invested in strengthening the ETMI-PLUS in the MAB, a return of almost 4 pesos would have been obtained thanks to the improvements in the vertical elimination of the 4 diseases and the reduction of cardiac complications in pregnant women.Conclusions: these results suggest the existence of a return / investment relationship favorable to the intervention, analyzed under a conservative analysis since savings for the health system are exclusively included and other dimensions of returns associated with improvements in results are excluded.

Hepatocellular carcinoma: A real-life experience in a specialized center in Bogotá, Colombia / Hepatocarcinoma: experiencia de la vida real en un centro especializado de Bogotá, Colombia

Abstract Introduction: Hepatocellular carcinoma (HCC) is the most frequent malignant primary liver tumor globally. In 2018, it ranked sixth and represented the fourth cause of death from cancer; the five-year overall survival is 18 %. Most cases of HCC develop in patients with cirrhosis of any etiology, especially because of hepatitis B and C viruses, alcohol, and recently nonalcoholic steatohepatitis (NASH). Aim: To analyze the clinical characteristics, diagnostic methods, treatments, prognostic variables, and survival. Materials and methods: This retrospective descriptive study was conducted on a cohort of patients diagnosed with cirrhosis and treated between January 2011 and December 2020 at a health care center in Bogotá. The diagnosis of HCC was confirmed radiologically or by biopsy. We analyzed the information descriptively with absolute frequency measures in the case of categorical variables. For continuous variables, the information was summarized with measures of central tendency (mean or median) and their relevant measures of dispersion. Results: We included 152 patients diagnosed with HCC, with a mean age of 69.4 years; 51.3 % were men. The leading cause of HCC was nonalcoholic fatty liver disease (NAFLD), which accounted for almost a third of cases (32 %); other causes were alcohol (15 %) and hepatitis C virus (14 %). The median manifestation of the tumor was two nodules with a size close to 4 cm. Besides, 35 % of patients had a BCLC (Barcelona Clinic Liver Cancer) stage with curative options, and 25 % received curative treatment options. The first-line systemic therapy used in this cohort was sorafenib®, used in 35 patients (33.7 %). Survival curves showed that women, Child-Pugh class A, and BCLC stage 0 had higher median survival. Multivariate analysis showed a higher risk of death for males (hazard ratio [HR]: 2.16; confidence interval [CI]: 1.24-3.76), Child-Pugh class B (HR: 2.14; CI 1.16-3.95), and Child-Pugh class C (HR: 7.52; CI 2.88-19.57). Conclusions: NAFLD is the leading cause of HCC in this cohort. A third of patients are diagnosed in early BCLC stages with a curative treatment option, and 25 % are treated with curative therapies. Sorafenib was the first-line therapy in advanced HCC. Overall survival after diagnosis of HCC remains low, being necessary to join forces in the follow-up of patients with cirrhosis to improve these outcomes.

Resumen Introducción: el hepatocarcinoma (HCC) es el tumor hepático primario maligno más frecuente en el mundo: en 2018 ocupó la sexta posición y representó la cuarta causa de muerte por cáncer; la supervivencia global a 5 años es del 18 %. La mayoría de los casos de HCC se desarrolla en pacientes con cirrosis de cualquier etiología, especialmente por virus de la hepatitis B y C, alcohol y, recientemente, por la esteatohepatitis no alcohólica (NASH). Objetivo: analizar las características clínicas, métodos de diagnóstico, tratamientos, variables pronósticas y supervivencia. Metodología: estudio descriptivo retrospectivo de una cohorte de pacientes con diagnóstico de cirrosis atendidos entre enero de 2011 y diciembre de 2020 en un centro de atención médica de Bogotá, con diagnóstico de HCC confirmado radiológicamente o por biopsia. La información se analizó de forma descriptiva con medidas de frecuencia absoluta en el caso de las variables categóricas; para las variables continuas se resumió la información con medidas de tendencia central (media o medianas) y su respectiva medida de dispersión. Resultados: se incluyeron 152 pacientes diagnosticados con HCC, con edad promedio de 69,4 años, 51,3 % eran hombres. La principal causa de HCC fue el hígado graso no alcohólico (NAFLD), que representó casi una tercera parte de los casos (32 %); otras causas fueron el alcohol (15 %) y el virus de la hepatitis C (14 %). La mediana de presentación del tumor fue de 2 nódulos con un tamaño cercano a 4 cm. El 35 % de los pacientes tenía un estadio BCLC (Barcelona Clinic Liver Cancer) con opciones curativas y el 25 % de los pacientes recibió opciones curativas de tratamiento. La terapia sistémica de primera línea utilizada en esta cohorte fue el sorafenib®, que se utilizó en 35 pacientes (33,7 %). Las curvas de supervivencia mostraron que las mujeres, el estadio Child-Pugh A y el estadio BCLC 0 presentaron mayores medianas de supervivencia. El análisis multivariado evidenció un mayor riesgo de muerte al ser hombre (Hazard ratio [HR]: 2,16; intervalo de confianza [IC]: 1,24 a 3,76), estar en los estadios Child-Pugh B (HR: 2,14; IC: 1,16 a 3,95) y Child-Pugh C (HR: 7,52; IC: 2,88 a 19,57). Conclusiones: el NAFLD es la principal causa de HCC en la presente cohorte, una tercera parte de los pacientes se diagnostica en estadios BCLC tempranos con opción curativa de tratamiento, y un 25 % se trata con terapias curativas. El sorafenib fue la terapia de primera línea en HCC avanzado. La supervivencia global luego del diagnóstico de HCC sigue siendo baja, y es necesario aunar esfuerzos en el seguimiento de los pacientes con cirrosis para mejorar estos resultados.

HIV, Hepatitis B, Hepatitis C, and Syphilis: prevalence and serodiscordance between women and their partners / HIV, hepatite B, hepatite C e sífilis: prevalência e sorodiscordância entre mulheres e seus companheiros

Introduction: The prevention of vertical transmission of sexually transmitted diseases is the object of research by several authors, who reinforce the importance of knowing the serological status of a woman's sexual partner. Objective: To evaluate the prevalence and serodiscordance of HIV, hepatitis B, hepatitis C, and syphilis infections among women admitted to a maternity hospital in southern Brazil and their partners. Methods: 350 women and their partners were interviewed in a service-based cross-sectional study conducted from August 16 to November 23, 2018. Results: 4.0% of the women and 4.3% of the men had one of the infections studied. Among women, 2.0% already knew they were HIV positive, 2.0% had a positive rapid test for syphilis and there was no positive result for hepatitis B or C. A total of 299 (85.4%) partners were located. Of these, 293 (98.0%) agreed to answer the study questionnaire. Of all men interviewed, 281 (95.9%) agreed to undergo an rapid test. Among men, 1.4% already knew they were HIV positive and 0.4% had chronic hepatitis B disease. There was a similar percentage of men with a positive rapid test for syphilis and hepatitis C (1.4%). Regarding couples, 6.8% had some positive test. Most of the positive test subjects were in a serodiscordant relationship (16 serodiscordant couples and 3 positive concordant couples). Conclusion: These results reinforce the importance of testing men to prevent the infection of a negative partner and the vertical transmission of sexually transmitted infections. The high acceptance, by men, to undergo an rapid test at the time of the woman's hospitalization demonstrated the viability of this strategy in the maternity ward.

Introdução: A prevenção da transmissão vertical de doenças sexualmente transmissíveis é objeto de pesquisa de diversos autores, os quais reforçam a importância do status sorológico do parceiro sexual da mulher. Objetivo: Avaliar a prevalência e a sorodiscordância de infecções por HIV, hepatite B, hepatite C e sífilis em mulheres internadas em uma maternidade localizada no Sul do Brasil e seus parceiros. Métodos: Foram entrevistadas 350 mulheres e seus parceiros em um estudo transversal de base de serviço realizado de 16 de agosto a 23 de novembro de 2018. Resultados: Do grupo consultado, 4,0% das mulheres e 4,3% dos homens apresentaram alguma das infecções estudadas. Entre as mulheres, 2% já sabiam ser HIV positivas e 2% apresentaram teste rápido positivo para sífilis. Para hepatite B ou C, não se registrou nenhum resultado positivo. Foram localizados 299 (85,4%) companheiros, destes, 293 (98,0%) aceitaram responder ao questionário do estudo. Do total de homens entrevistados, 281 (95,9%) concordaram em se submeter aos testes rápidos, entre eles, 1,4% já sabiam ser HIV positivos, 0,4% eram portadores crônicos de hepatite B e 1,4% apresentaram testes rápidos positivos para sífilis e hepatite C. Em relação aos casais, 6,8% possuíam algum teste positivo, a maioria (16) era formada de indivíduos sorodiscordantes e 3 de concordantes positivos. Conclusão: Esses resultados reforçam a importância da testagem masculina com a intenção de evitar a infecção do cônjuge negativo e a transmissão vertical das infecções sexualmente transmissíveis. A alta aceitação masculina de se submeter ao teste rápido durante a internação da mulher demonstrou a viabilidade dessa estratégia de testagem na maternidade.

Evaluation of Aids and Hepatitis-B knowledge and job satisfaction among hairdressers and barbers in Turkey

Blood-borne viruses, includingthe human immunodeficiency virus and hepatitis B virus, have certain common epidemiological characteristics and these viruses infect millions of people worldwide. This study aimed to determine the job satisfaction and the level of knowledge and practices regarding infectious diseases of employees working as hairdressers and barbers.This descriptive and cross-sectional study comprised 1200 hairdressers and barbers. The study sample comprised 628 people who consented to participate in the study. The mean age of the participants who participated in the study was 28, 13 ± 6. 9 years. The mean job satisfaction score of the participants was 3.85 ± 0.58. The job satisfaction score was found to be higher among those with sufficient knowledge of hepatitis B (p < 0.005).

It is recommended that employees be encouraged to wear gloves and gowns to protect their health and prevent contamination.

Serological prevalence of hepatitis B virus (HBV) in Mardan district, Khyber Pakhtunkhwa, Pakistan / Prevalência sorológica do vírus da hepatite B (HBV) no distrito de Mardan, Khyber Pakhtunkhwa, Paquistão

Hepatitis B virus infection is perilous among the five types of Hepatitis, as it remains clinically asymptomatic. The present study draws up-to-date prevalence of Hepatitis B virus (HBV) in the general population of Mardan, Khyber Pakhtunkhwa Pakistan. The blood samples from 4803 individuals including 2399 male and 2404 females were investigated. All the suspected samples were analyzed for hepatitis B surface antigen using Immuno-chromatographic test (ICT), Enzyme-linked immunosorbent assay (ELISA), and followed by Reverse transcription-polymerase chain reaction (RT-PCR). Results showed that 312 (13.00%) out of 2399 individuals contained antibodies in their blood against HBV, while among the different age groups, the highest incidences of HBV antibodies were found in the age of 21-30 groups (10.73%). Furthermore, the ICT positive samples were screened by nested polymerase chain reaction to detect the existence of active HBV-DNA. It was observed that 169 (7.04%) out of (2399) male of the total population (4803) tested was positive. On the other hand, the female 463 (19.25%) possessed antibodies in their blood against HBV. Accumulatively, our results showed a higher percentage of HBV prevalence in males than females in the age group 21-30 years. The total HCV infected in Mardan general population was recorded at 5.7% comprising both male and female.

A infecção pelo vírus da hepatite B é perigosa entre os cinco tipos de hepatite, pois permanece clinicamente assintomática. O presente estudo traça a prevalência atualizada do vírus da hepatite B (HBV) na população geral de Mardan, Khyber Pakhtunkhwa, no Paquistão. Amostras de sangue de 4.803 indivíduos, incluindo 2.399 homens e 2.404 mulheres, foram investigadas. Todas as amostras suspeitas foram analisadas para o antígeno de superfície da hepatite B usando teste imunocromatográfico (ICT), enzyme-linked immunosorbent assay (ELISA), seguido por transcrição reversa-reação em cadeia da polimerase (RT-PCR). Os resultados mostraram que 312 (13,00%) de 2.399 indivíduos continham anticorpos no sangue contra o VHB, enquanto, entre as diferentes faixas etárias, as maiores incidências de anticorpos VHB foram encontradas nos grupos de 21 a 30 anos (10,73%). Além disso, amostras positivas para ICT foram rastreadas por reação em cadeia da polimerase aninhada para detectar a existência de HBV-DNA ativo. Observou-se que 169 (7,04%) de 2.399 homens do total da população (4803) testados foram positivos. Por outro lado, 463 mulheres (19,25%) possuíam anticorpos no sangue contra VHB. Acumulativamente, nossos resultados mostraram uma porcentagem maior de prevalência de HBV em homens do que em mulheres na faixa etária de 21 a 30 anos. O total de HCV infectados na população geral de Mardan foi registrado em 5,7%, incluindo homens e mulheres.

Epidemiological profile of viral hepatitis infection in the population treated at a reference hospital in Alagoas / Perfil epidemiológico da infecção por hepatite viral na população atendida em hospital de referência em Alagoas

Viral hepatitis are widely spread infectious diseases caused by a variety of etiological agents that displays liver tropism as a common characteristic. A descriptive, cross-sectional, observational and retrospective study was conducted through the analysis of viral hepatitis medical records treated and diagnosed from 2010 to 2015. The relationship between the variables were made through the chi-square test. 632 viral hepatitis medical records were analyzed. The highest number of cases happened in 2011. Hepatitis A virus (HAV) infection was predominant. The most affected age group was < 20 years and the highest number of cases observed in this age group was related to HAV (p<0.001). The acute clinical form was predominant, with 70.2% of the cases. 92.3% of which corresponded to HAV infection (p<0.001). Most of the cases occurred in the brown race and male gender. Moreover, regarding the probable source/mechanism of infection, the contact with suspicious water/food for hepatitis A cases was highlighted. The sexual form predominated in HBV infection and previous history of blood transfusion in cases of hepatitis C. Most cases were spotted in the mesoregion of Eastern Alagoas, especially in the capital Maceió. It must be observed the importance of knowing the profile of this disease in order to understand its dissemination and thus have subsidies for the creation of actions and strategies to combat the infection.

A hepatite viral é uma doença infecciosa amplamente difundida causada por uma variedade de agentes etiológicos que exibem o tropismo hepático como uma característica comum. Um estudo descritivo, transversal, observacional e retrospectivo foi realizado por meio da análise de prontuários de hepatites virais tratados e diagnosticados de 2010 a 2015. A relação entre as variáveis foi feita através do teste qui-quadrado. Foram analisados 632 prontuários de hepatite sustero. O maior número de casos aconteceu em 2011. A infecção pelo vírus da hepatite A (HAV) foi predominante. A faixa etária mais atingida foi < 20 anos e o maior número de casos observados nessa faixa etária foi relacionado ao HAV (p<0,001). A forma clínica aguda foi predominante, com 70,2% dos casos. 92,3% dos quais corresponderam à infecção por HAV (p<0,001). A maioria dos casos ocorreu na raça parda e no sexo masculino. Além disso, quanto à provável fonte/mecanismo de infecção, foi destacado o contato com água/alimento suspeitos para os casos de hepatite A. A forma sexual predominou na infecção pelo HbV e histórico anterior de transfusão de sangue em casos de hepatite C. A maioria dos casos foi avistada na mesorregião do Leste de Alagoas, especialmente na capital Maceió. Deve-se observar a importância de conhecer o perfil dessa doença para entender sua disseminação e, assim, contar com subsídios para a criação de ações e estratégias de combate à infecção.
