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.

OBJECTIVE@#To measure the burden of hepatitis B-associated diseases in China from 1990 to 2019, and to predict its changes from 2020 to 2030.@*METHODS@#The age-standardized prevalence, incidence, mortality and disability-adjusted life years (DALY) rate of hepatitis B-associated diseases in China from 1990 to 2019 were extracted from the Global Burden of Disease 2019 (GBD 2019) data resources, and the trends in burdens of hepatitis B-associated diseases were evaluated from 1990 to 2019 using estimated annual percentage change (EAPC) and annual percent change (APC). In addition, the changes in the burden of hepatitis B-associated diseases were predicted in China from 2020 to 2023 using the Bayesian model.@*RESULTS@#The overall incidence of hepatitis B-associated diseases reduced from 2 725.98/105 in 1990 to 1 397.31/105 in 2019 in China [estimated annual percentage change (EAPC) = -2.35%, 95% confidential interval (CI): (-2.58%, -2.13%)], with a reduction in the prevalence from 12 239.53/105 in 1990 to 6 566.12/105 in 2019 [EAPC = -2.34%, 95% CI: (-2.54%, -2.14%)], a reduction in the mortality from 24.67/105 in 1990 to 8.07/105 in 2019 [EAPC = -4.92%, 95% CI: (-5.37%, -4.47%)], and a reduction in the DALY rate from 793.38/105 in 1990 to 247.71/105 in 2019 [(EAPC = -5.15%, 95% CI: (-5.64%, -4.66%)]. The DALY rate of hepatitis B-associated diseases were mainly attributed to liver cancer, and the DALY rate of hepatitis B-associated diseases appeared a tendency towards a rise in China from 2012 to 2019 [APC = 1.30%, 95% CI: (0.16%, 2.45%)]. The overall burden of hepatitis Bassociated diseases was higher in males than in females, and the DALY rate of hepatitis B-associated diseases increased with age, with the greatest DALY rate seen among patients at ages of 50 to 69 years. The overall incidence of hepatitis B-associated diseases was projected to be 866.79/105 in China in 2030, with the greatest incidence seen in acute hepatitis B (854.87/105), and the burden of hepatitis B-associated diseases was predicted to decline in China from 2020 to 2030; however, the burden of liver disease was projected to appear a tendency towards a rise.@*CONCLUSIONS@#The burden of hepatitis B-associated diseases appears an overall tendency towards a decline in China from 1990 to 2030; however, the burden of liver cancer appears a tendency towards aggravation. Early diagnosis and treatment of liver cancer should be given a high priority.

Objective: To analyze the repetitive reporting of hepatitis B in Fujian province during 2016-2020, and provide evidence for the improvement of hepatitis B surveillance. Methods: The reporting cards from the China Information System for Disease Control and Prevention were collected and divided into repetitive reporting cards and non-repetitive reporting cards from the report cards collected according to the valid ID number on the cards, and the proportion of repetitive report cards and related factors were analyzed by using software SAS 9.4. Results: A total of 314 551 hepatitis B reporting cards were submitted in Fujian from 2016 to 2020, in which 90.93% (286 020/314 551) were included in the analysis. The repetitive reporting cards accounted for 10.48% (29 982/286 020). The annual proportion of the repetitive reporting cards from 2016 to 2020 was between 2.98% and 3.71%, showing an overall increasing trend year by year (Z=2.26, P=0.024). The proportions of the repetitive reporting cards in 1-5 years were 3.17%, 5.40%, 7.74%, 9.27% and 10.48%, respectively, showing an increase trend with year (Z=128.16, P<0.001). The proportions of the repetitive reporting cards in 10 areas of Fujian ranged from 5.44% to 13.48% with significant difference (χ2=2 050.41, P<0.001) and increased with the increase of reported incidence of hepatitis B (Z=26.92, P<0.001). There were significant differences in relationships between repetitive reporting proportion and sex, age and type of the cases between the areas with high incidence and low incidence of hepatitis B. Conclusions: The reported incidence of hepatitis B was seriously affected by the repetitive reporting in Fujian from 2016 to 2020. A cross-year and cross-area surveillance mechanism for hepatitis B should be established and targeted measures should be taken to strengthen the control of the repetitive reporting and improve the surveillance for hepatitis B.

Objective: To explore the role of nonalcoholic fatty liver disease (NAFLD) in the development of hepatocellular carcinoma (HCC) in patients with prior hepatitis B virus infection (HBsAg-negative and anti-HBC-positive). Methods: 1605 hospitalized patients who were first diagnosed with HCC at Nanfang Hospital between 2015 to 2017 were retrospectively studied. Patients who developed HCC on the basis of active HBV infection (HBsAg-positive, anti-HBc positive) were used as control. Multivariate logistic regression model was used to analyze the relationship between NAFLD and HCC in patients with prior hepatitis B virus infection. Results: Among HCC patients with both HBsAg and anti-HCV negative, the proportion of prior HBV infection accounted for 86.7%. NAFLD prevalence was higher in patients with HCC based on prior HBV infection than active HBV infection (19.7% vs. 8.5%, P < 0.001). After adjusting for gender, age, hypertension, alanine aminotransferase, and liver cirrhosis, patients with HCC based on prior HBV infection were more likely to develop NAFLD (OR: 2.29, 95% CI: 1.40-3.74), and this phenomenon was observed only in patients with non-cirrhosis (OR: 5.26, 95% CI: 2.53-10.96) and aged≥50 years (OR: 2.36, 95% CI: 1.33-4.20). Conclusion: NAFLD may be a risk factor for HCC in a previously infected patients with HBV, especially in non-cirrhotic and population aged≥50 years.

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.

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.

ABSTRACT OBJECTIVE To determine the seroprevalence of hepatitis B and C among immigrants residing refugee camps in Muzaffarabad, Azad Kashmir, Pakistan, and to identify possible risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) transmission. METHODS Around 1,225 individuals inhabiting Muzaffarabad refugee camps, participated in the study. A qualitative Immuno-Chromatographic Technique was used for initial screening and PCR test was used for detection of HBV and HCV in participants. The major risk factors for HBV and HCV transmission were assessed using a questionnaire approach. RESULTS Around 86 (7.0%) individuals were observed for hepatitis B surface antigen (HBsAg) presence, and 215 (17.5%) individuals were found positive for Anti-HCV. Only 32 (2.6%) individuals were confirmed for HBV DNA and 126 (10.3%) individuals were positive for HCV RNA after PCR. Demographically, both HBsAg and Anti-HCV were found more prevalent in female (4.4% HBsAg and 10.8% Anti-HCV) population as compared to male (2.6% HBsAg and 6.7% Anti-HCV) population. Surprisingly, the HBsAg (23.5%) and Anti-HCV (41.1%) appeared to be more frequent in the age group 62-75 years. Previous history of hepatitis in the family (p < 0.0001), blood transfusion (p = 0.0197) dental treatment (p < 0.0001) and tattooing or piercing on any part of the body (p = 0.0028) were assessed as significant risk factors in HBV and HCV transmission. CONCLUSIONS Presence of 7.0% HBsAg and 17.5% Anti-HCV in a small fragment of the migrant population cannot be overlooked. Lack of awareness among people and negligence of health department could escalate the situation.

Introducción. La seguridad transfusional es el objetivo primordial de los bancos de sangre, sin embargo, conlleva un alto riesgo de eventos adversos como son las infecciones transmisibles por transfusión (ITT). El conocimiento de la prevalencia de estas infecciones fue de particular interés en esta investigación, donde se determinó su frecuencia, coinfección y relación con el tipo de donantes admitidos. Metodología. Estudio observacional retrospectivo de 2017 y 2018, en el que se incluyeron todos los registros de donantes de sangre que contenían datos demográficos y resultados de los marcadores obligatorios en el país (Ecuador), tanto de pruebas serológicas como moleculares. Se obtuvo el permiso del custodio de la información y del subcomité de bioética de investigaciones en seres humanos. Para el análisis de los datos se utilizó estadística descriptiva e inferencial. Resultados. Se determinó una prevalencia del 3,18 % de resultados reactivos para una o más ITT, el rango de edad más prevalente fue de 29 a 40 años, el 89,8 % fueron donantes compensatorios, y de ellos el 90 % fueron reactivos para una o más ITT. El marcador serológico más prevalente fue el anti-core del virus de la hepatitis B (anti-HBc), seguido por el de sífilis y los anticuerpos contra el virus de la hepatitis C (VHC). La coinfección más prevalente fue con sífilis y hepatitis B. Se encontró una diferencia estadísticamente significativa entre los resultados obtenidos en las pruebas serológicas y las moleculares (x2=26,9; p=0,000). Conclusión. Las ITT en los bancos de sangre son un riesgo latente, por lo que es necesario conocer las variaciones epidemiológicas que existen en cada población. El conocimiento de la prevalencia de las ITT en donantes de sangre permite establecer nuevas estrategias de selección del donante, que garanticen la mejor seguridad posible en las transfusiones, además debe verificarse siempre la metodología utilizada y hacer monitoreo permanente del sistema de calidad establecido
Introduction. Transfusion safety is the primary objective of blood banks, however one of the adverse reactions to blood transfusion are the transfusion transmissible infections (TTIs). Knowledge of the prevalence of these infections was of particular interest in this study where we determined their frequency, co-infection and relationship with the type of donors admitted. Methodology. Retrospective observational study during 2017 and 2018, in which all blood donor records containing demographic data and results of the country's (Ecuador) mandatory serological markers of both serological and molecular tests were included. Permission was obtained from the data custodian and the Human Research Bioethics Subcommittee. Descriptive and inferential statistics were used for data analysis. Results. A prevalence of 3,18% of reactive results to one or more TTIs was determined, the most prevalent age range was 29 to 40 years, 89.8% were compensatory donors and 90% of them were reactive to one or more TTIs. The anti- core serological marker of the hepatitis B virus (anti-HBc) was the most prevalent, followed by syphilis and hepatitis C antibodies. Syphilis and hepatitis B were identified as the most prevalent coinfection. The correlation between the results obtained in the serological and molecular tests was determined to be different and statistically significant (x2=26.9; p=0.000). Conclusion. TTIs in blood banks are a latent risk, so it is necessary to know the epidemiological variations that exist in every population. Knowledge of the prevalence of TTIs in blood donors facilitates new donor selection strategies that guarantee the best possible safety in transfusions. In addition, the methodology used must always be verified and the established quality system must be permanently monitored

Objetivo: Apesar da disponibilidade e orientações acerca da vacinação contra o vírus da hepatite B (VHB), observa-se que a cobertura vacinal e o conhecimento entre os profissionais de Odontologia não são satisfatórios, especialmente nos países em desenvolvimento. Como um alerta aos estudantes e profissionais de Odontologia, o objetivo deste estudo é revisar a literatura acerca da infecção pelo VHB na prática odontológica. Materiais e métodos: Trata-se de uma revisão narrativa. Os artigos incluídos foram pesquisados nas bases de dados Pubmed, Scielo e Lilacs, utilizando os descritores "Hepatitis B virus" e "Dentist", no período de 2000 a 2020. Revisão de literatura: Os conhecimentos acerca do VHB devem ser incentivados durante a graduação, uma vez que os cirurgiões-dentistas desempenham papel importante na prevenção desta doença. A hepatite B é mais prevalente entre os cirurgiões-dentistas do que na população geral. Nesses profissionais, a transmissão acontece principal-mente durante o uso e descarte de instrumentos cortan-tes contaminados com sangue ou saliva infectada. Além disso, como as secreções nasofaríngeas carregam o vírus, embora remota, ainda existe a possibilidade de infecção por aerossol. Discussão: Dentre as formas de prevenção, podemos citar a realização do esquema vacinal completo, as orientações para manejo odontológico de pacientes com hepatite, a adoção às normas de biossegurança e os métodos corretos para limpeza e desinfecção e esterilização dos materiais. Conclusão: Os cirurgiões-dentistas possuem um risco maior de exposição à infecção pelo HBV do que o restante da população. Portanto, esses profissionais devem dispor de atenção especial às estratégias de prevenção contra a hepatite
Aim: Despite the availability and guidance regarding the hepatitis B virus (HBV) vaccination, it is observed that the vaccine coverage and knowledge among dental professionals are not satisfactory, especially in developing countries. As a warning to dental students and professionals, the aim of this study is to review the literature on HBV infection in dental practice. Materials and methods: This is a narrative review. The articles included were searched in the Pubmed, Scielo and Lilacs databases, using the des-criptors "Hepatitis B virus" and "Dentist", from 2000 to 2020. Literature review: Knowledge about HBV should be encouraged during graduation, since dentists play an im-portant role in preventing this disease. Hepatitis B is more prevalent among dentists than in the general population. In these professionals, the transmission occurs mainly due to a percutaneous injury involving the use and disposal of cutting instruments contaminated with the infected patient's blood or saliva. In addition, as nasopharyngeal secretions carry the virus, although remote, there is still the possibility of aerosol infection. Discussion: Among the forms of prevention, we can mention the accomplishment of the complete vaccination schedule, the guidelines for the dental management of patients with hepatitis, the adoption of biosafety standards and the correct methods for cleaning, disinfecting and sterilizing the materials. Conclusion: Dentists have higher risk of exposure to HBV infection than the rest of the population. Therefore, these professionals must pay special attention to strategies for preventing hepatitis.

Abstract Objectives: to calculate the prevalence and rate per 1,000 live births of sexually transmitted infections (STI) in pregnant women at a public maternity hospital in Salvador. Methods: this descriptive, cross-sectional study retrospectively collected data from compulsory notifications and medical records of pregnant women with STI seen at a maternity hospital in northeastern Brazil between 2014 and 2017 (n = 520). Prevalence and rate per 1,000 live births were estimated for hepatitis B, hepatitis C, HIV, and syphilis. Associations between STI and other clinical and sociodemographic variables were investigated. Results: most pregnant women were born and resided in Salvador, presented a mean age of 26.4 years, self-reported mixed-race and had unplanned pregnancies. Prevalence and rates per 1,000 live births were, respectively: 0.26% and 3.39 for hepatitis B, 0.06% and 0.79 for hepatitis C, 0.47% and 6.23 for HIV, and 2.46% and 32.2 for syphilis. Conclusion: higher prevalence and rates of infection per 1,000 live births were seen at the maternity hospital in northeastern Brazil compared to official data provided by the Brazilian government, notably with regard to HIV and syphilis. The appropriate epidemiological notification of STI, especially in pregnant women, enables the elaboration of effective preventive strategies incorporating specific sociodemographic and clinical characteristics.
Resumo Objetivos: calcular a prevalência e as taxas por 1000 nascidos vivos de infecções sexualmente transmissíveis (IST) em gestantes de uma maternidade pública de Salvador. Métodos: estudo transversal, descritivo, com dados coletados retrospectivamente a partir das fichas de notificação dos agravos e dos prontuários de todas as gestantes com IST atendidas na maternidade, entre os anos de 2014 e 2017 (n=520). Foram calculadas as prevalências e as taxas por 1000 nascidos vivos de hepatite B, hepatite C, HIV e sífilis para a população de gestantes da maternidade. Associações entre as IST e demais variáveis clínicas e sociodemográficas também foram investigadas. Resultados: a maioria das gestantes era natural e residente de Salvador, pardas, com idade média de 26,4 anos e que não planejaram a gravidez. As prevalências e as taxas por 1000 nascidos vivos foram respectivamente: 0,26% e 3,39 para hepatite B, 0,06% e 0,79 para hepatite C, 0,47% e 6,23 para HIV e 2,46% e 32,2 para sífilis. Conclusão: a maternidade apresenta prevalências e taxas por 1000 nascidos vivos superiores aos dados oficiais do governo brasileiro, especialmente para HIV e sífilis. A correta notificação epidemiológica desses agravos, especialmente em gestantes, permite o desenvolvimento de estratégias preventivas mais eficientes e com enfoque nas características sociodemográficas e clínicas das pacientes.

ABSTRACT BACKGROUND: Viral hepatitis is a global phenomenon, with the disease burden varying on a daily basis. Amongst chronic infections, hepatitis B virus and hepatitis C virus (HCV) are egregiously linked to severe health-related complications, with a worldwide prevalence of 248 million and 71 million respectively. Amongst the developing world, a hand full of countries are exhibiting a gross decline in chronic viral infection prevalence, like Bangladesh. While countries such as India have a consistent prevalence, Pakistan bears one of the largest proportions of chronic viral hepatitis globally with increasing trends shown year-by-year. Various old literature texts have stated an approximate national prevalence rate around 2.6% and 5.3% of hepatitis B and C respectively. OBJECTIVE: The objective of this study was to determine the current seroprevalence rates of chronic viral hepatitis amongst the general population of rural Sindh using a screening program to determine the current disease burden. METHODS: An observational, cross-sectional survey based on a screening program was conducted in 5 districts with a combined population of over 6.5 million. The screening was carried out via the administration of various camps with the assistance of local social workers and welfare organizations. A total of 24,322 individuals met the inclusion criteria and were screened through (HBsAg/HCV) rapid test cassette (WC) Imu-Med one-step diagnostic test. RESULTS: Hepatitis B was found positive in 964 (3.96%) individuals including 421 (43.67%) males and 543 (56.32%) females, while hepatitis C was positive in 2872 (11.80%) individuals including 1474 (51.32%) males and 1398 (48.67%) females. The prevalence amongst the districts varied between 0.97% and 9.06% for hepatitis B, and 1.61% and 29.50% for hepatitis C, respectively. Umerkot was found to be the most prevalent district amongst rural Sindh, while Badin had the least number of seropositive people. The second most prevalent district of the study population was found to be Tando Allahyar followed by Mirpur Khas. The combined seroprevalence of 15.76% was calculated for hepatitis B and C together amongst the five studied districts of rural and peri-urban Sindh. CONCLUSION: The alarmingly high prevalence rates revealed in our study warrant the urgent need to generate multiple effective strategies in the region to enhance awareness amongst the general population regarding screening, prevention, and prompt treatment of the disease.
RESUMO CONTEXTO: A hepatite viral é um fenômeno global, com a intensidade da doença variando diariamente. Entre as infecções crônicas, o vírus da hepatite B e o vírus da hepatite C (VHC) estão fortemente ligados a complicações graves relacionadas à saúde, com prevalência mundial de 248 milhões e 71 milhões, respectivamente. Entre o mundo em desenvolvimento, uma quantidade de países está exibindo um declínio bruto na prevalência de infecção viral crônica, tal como Bangladesh. Embora países como a Índia tenham uma prevalência consistente, o Paquistão tem uma das maiores proporções globais de hepatite viral crônica, com tendências crescentes mostradas ano a ano. Vários textos da menos recentes têm declarado uma taxa de prevalência nacional aproximada em torno de 2,6% e 5,3% da hepatite B e C, respectivamente. OBJETIVO: O objetivo deste estudo foi determinar as atuais taxas de soroprevalência da hepatite viral crônica entre a população geral do Sindh rural utilizando um programa de triagem para determinar a carga atual da doença. MÉTODOS: Foi realizada uma pesquisa observacional e transversal baseada em um programa de triagem combinada em cinco distritos com população de mais de 6,5 milhões. A triagem foi realizada por meio da administração de diversos acampamentos com o auxílio de assistentes sociais locais e organizações de assistência social. Um total de 24.322 indivíduos atenderam aos critérios de inclusão e foram examinados através do teste rápido (HBsAg/VHC) Imu-Med em uma etapa. RESULTADOS: Hepatite B positiva foi encontrada em 964 (3,96%) indivíduos incluindo 421 (43,67%) homens e 543 (56,32%) mulheres, enquanto hepatite C foi positiva em 2.872 (11,80%) indivíduos incluindo 1.474 (51,32%) homens e 1.398 (48,67%) mulheres. A prevalência entre os distritos variou entre 0,97% e 9,06% para hepatite B, e 1,61% e 29,50% para hepatite C, respectivamente. Umerkot foi encontrado como o distrito mais prevalente entre Sindh rural, enquanto Badin tinha o menor número de pessoas soropositivas. O segundo distrito mais prevalente da população de estudos foi encontrado como Tando Allahyar, seguido por Mirpur Khas. A soroprevalência combinada de 15,76% foi calculada para hepatite B e C em conjunto entre os cinco distritos estudados do Sindh rural e periurbano. CONCLUSÃO: As taxas de prevalência alarmantemente reveladas em nosso estudo justificam a necessidade urgente de gerar múltiplas estratégias efetivas na região para aumentar a conscientização da população em geral sobre rastreamento, prevenção e tratamento rápido da doença.

Abstract Objective To evaluate the seroprevalence of positive markers for syphilis, human immunodeficiency virus (HIV) I and II, human T cell lymphotropic virus (HTLV) I and II, and hepatitis B and C among women undergoing in vitro fertilization (IVF). Methods We conducted a retrospective analysis among patients who underwent IVF, between January 2013 and February 2016, and who had complete screening records. Results We analyzed 1,008 patients who underwent IVF, amounting to 2,445 cycles. Two patients (0.2%) tested positive for HIV I and II and none for HTLV I and II. Three patients (0.3%) had positive screening for syphilis, and two (0.2%) had positive hepatitis C antibody test (anti-HCV). A positive hepatitis B virus surface antigen (HbsAg) test was observed in 4 patients (0.4%), while 47 (4.7%) patients were positive for IgG antibody to hepatitis B core antigen (anti-HbC IgG), and only 1 (0.1%) was positive for IgM antibody to hepatitis B core antigen (anti-HbC IgM). The anti-HbS test was negative in 659 patients (65.3%). Only 34.7% of the patients had immunity against the Hepatitis B virus. Patients with an anti-HbS negative result were older than those with a hepatitis B test (anti-HbS) positive result (36.3 versus 34.9; p<0.001). Conclusion The present study showed lower infection rates than the Brazilian ones for the diseases studied in patients undergoing IVF. Only a few patients were immunized against hepatitis B.
Resumo Objetivo Avaliar a soroprevalência de marcadores positivos para sífilis, vírus da imunodeficiência humana (HIV) I e II, vírus linfotrópicos de células T humanas (HTLV) I e II e hepatite B e C em mulheres submetidas a fertilização in vitro (FIV). Métodos Realizamos uma análise retrospectiva entre as pacientes submetidas a FIV, entre janeiro de 2013 e fevereiro de 2016, e que possuíam prontuários completos. Resultados Foram analisadas 1.008 pacientes submetidas a FIV, totalizando 2,445 ciclos. Duas pacientes (0,2%) apresentaram resultado positivo para HIV I e II, e nenhuma para HTLV I e II. Três pacientes (0,3%) apresentaram triagem positiva para sífilis, e duas (0,2%) apresentaram teste de pesquisa de anticorpos anti-HCV (anti-HCV) positivo. Um teste de antígeno de superfície do vírus da hepatite B (HbsAg) positivo foi observado em 4 pacientes (0,4%), enquanto 47 (4,7%) pacientes foram positivas para anticorpos IgG contra o antígeno de superfície da hepatite B (IgG anti-HbC), e apenas 1 (0,1%) foi positiva para anticorpos IgM contra o antígeno central da hepatite B (IgM anti-HbC). O teste de anticorpos contra hepatite B (anti-HbS) foi negativo em 659 pacientes (65,3%). Apenas 34,7% das pacientes tinham imunidade contra o vírus da hepatite B. Pacientes comresultado negativo anti-HbS erammais velhas do que aquelas com resultado positivo anti-HbS (36,3 versus 34,9; p<0,001). Conclusão Este estudo mostrou taxas de infecção inferiores às taxas brasileiras para as doenças estudadas em pacientes submetidas à FIV. Apenas alguns pacientes foram imunizados contra a hepatite B.

Resumo O objetivo deste artigo é analisar a distribuição espacial da vacina contra Hepatite B (VCHB) de gestantes. Estudo transversal, realizado com 266 puérperas. O registro da VCHB foi obtido por meio da caderneta de pré-natal. Para a detecção do cluster de risco para presença de registro ou ausência de VCHB foi utilizada a técnica de varredura espacial. Posteriormente a esta identificação do cluster, procedeu-se à comparação das variáveis individuais e ambientais entre as Áreas de Abrangência da Unidade Básica de Saúde (AA-UBS). A prevalência média de não VCHB foi de 88,34%. A análise de varredura espacial Scan observou-se um cluster de alta prevalência de puérperas que apresentava o registro da VCHB em suas cadernetas. Análises comparativas demonstraram que trabalho remunerado e o número de consultas realizadas no pré-natal estão associados positivamente a VCHB. Este trabalho suscita uma reflexão de possíveis disparidades com as demais AA-UBS, além da perspectiva a nível ambiental. Ressalta-se que a situação vacinal sofre influência não somente de fatores intrínsecos aos indivíduos, entretanto, nesse estudo, os resultados apontam que as variáveis individuais são majoritariamente mandatórias na decisão das gestantes em vacinarem.
Abstract The objective of this article is to analyze the spatial distribution of Hepatitis B vaccine (HBVAC) of pregnant women. This is a cross-sectional study carried with 266 puerperae. The HBVAC record was obtained through the prenatal care booklet. The spatial scanning technique was used to detect a cluster of risk for the presence or absence of an HBVAC record. After this cluster identification, the individual and environmental variables were compared between the Coverage Areas of Basic Health Units (CAs-BHUs). The mean prevalence of non-HBVAC was 88.34%. Scan spatial scan analysis observed a cluster of a high prevalence of puerperae with a HBVAC record. Comparative analyses have shown that paid work and the number of prenatal visits are positively associated with an HBVAC record. Given the above, this work brings a reflection on possible disparities with other CAs-BHUs, besides the influence of the environmental perspective. It should be emphasized that the vaccination situation is influenced not only by factors intrinsic to the individuals. However, in this study, the results indicate that individual variables are predominantly mandatory in the decision of HBVAC uptake among pregnant women.
