Antígeno nativo y no nativo para determinar la seroprevalencia de Trypanosoma cruzi en mujeres embarazadas en el estado de Morelos, México / Native and non-native antigen to determine the seroprevalence of Trypanosoma cruzi in pregnant women from the state of Morelos, Mexico

INTRODUCCIÓN: La enfermedad de Chagas es una infección parasitaria crónica sistémica, de importancia global, causada por Trypanosoma cruzi. OBJETIVO: Determinar la prevalencia de anticuerpos contra T cruzi en mujeres embarazadas en el estado de Morelos, México. MATERIALES Y MÉTODOS: Se analizaron 1.620 sueros de mujeres embarazadas mediante dos pruebas serológicas: ELISAc (antígeno crudo nativo) y ELISAr (antígeno recombinante, no nativo). Las muestras reactivas se analizaron posteriormente mediante hemaglutinación indirecta (HAI). Se utilizaron dos enfoques de detección, en paralelo (son positivas las muestras reactivas por cualquier método) y en serie (son positivas las muestras confirmadas por HAI). Se evaluaron factores sociodemográficos y de salud asociados a la presencia de anticuerpos contra T. cruzi mediante razones de momios al 95%. RESULTADOS: Se obtuvo una seroprevalencia de 4,87% con el diagnóstico en paralelo y de 0,43% en serie. A partir de los resultados en paralelo las mujeres que fueron atendidas en los hospitales generales de Tetecala y Jojutla tuvieron, respectivamente, 2,2 y 2,0 veces mayor posibilidad de presentar anticuerpos contra T cruzi con respecto a las mujeres que fueron atendidas en el Hospital General de Cuautla. CONCLUSIÓN: La prevalencia de anticuerpos contra T cruzi en mujeres embarazadas en el estado de Morelos fluctuó entre 0,43 y 4,87%, según el antígeno y el abordaje utilizado. Es necesario continuar con la vigilancia de la seroprevalencia de anticuerpos contra T cruzi en mujeres embarazadas en el estado de Morelos, México, con las técnicas de mayor sensibilidad y especificidad disponibles.

BACKGROUND: Chagas disease is a globally important chronic systemic parasitic infection caused by Trypanosoma cruzi. AIM: To determine the prevalence of antibodies against T cruzi in pregnant women from the state of Morelos, México. METHODS: 1,620 sera from pregnant women were analyzed using two serological tests: ELISAc (native crude antigen) and ELISAr (recombinant, non-native antigen). Reactive samples were subsequently analyzed by indirect hemagglutination (IHA). Two detection approaches were used, in parallel (reactive samples by any method are positive) and serial (samples confirmed by IHA are positive). Sociodemographic and health factors associated with the presence of antibodies against T cruzi were evaluated using 95% odds ratios. RESULTS: A seroprevalence of 4.87% was obtained with parallel diagnosis and 0.43% in series. From the parallel results, the women who were attended at the general hospitals of Tetecala and Jojutla had respectively 2.2 and 2.0 times greater chance of presenting antibodies against T cruzi compared to the women who were attended at the General Hospital of Cuautla. CONCLUSION: The prevalence of antibodies against T cruzi in pregnant women from the state of Morelos fluctuated between 0.43 and 4.87%, depending on the antigen and the approach used. It is necessary to continue with the surveillance of the seroprevalence of antibodies against T cruzi in pregnant women from the state of Morelos, Mexico, using the techniques with the highest sensitivity and specificity available.

Territory, neglected diseases and the action of community and endemic combat agents / Território, doenças negligenciadas e ação de agentes comunitários e de combate a endemias

ABSTRACT OBJECTIVE To characterize knowledge, practices, and professional experience of community health agents (ACS) and endemic combat agents (ACE) on leprosy and Chagas disease (DC), during participation in an integrated training workshop in the IntegraDTNs-Bahia project. METHODS Descriptive and exploratory case study, involving health agents and endemic combat agents participating in a training workshop on the shared role of these professionals in health care and surveillance processes. The project was developed in the municipalities of Anagé, Tremedal and Vitória da Conquista, in the southwestern State of Bahia, 2019-2020. A specific instrument was applied, with questions related to knowledge and practices of surveillance and care for leprosy and Chagas disease. Descriptive analysis of the data, in addition to consolidation of the lexical analysis, was performed. RESULTS Out of a total of 135 participants (107 ACS and 28 ACE), 80.7% of them have been working for at least 12 years, without previous participation in joint training processes. Only 17.9% of endemic combat agentes reported having participated in training on leprosy and none reported developing specific actions to control the disease. For Chagas disease, 36.4% of community health agents participated in training more than a decade before, while for 60.7% of endemic combat agents the last training was carried out in the last five years. The development of educational actions for Chagas disease was more frequent for endemic combat agents (64.3%). When asked about ways of recognizing diseases, the term "skin spots" was the most reported (38 times) for leprosy and, for Chagas disease, the term "I don't know" (17 times). CONCLUSION Processes of health agents and endemic combat agents action in realities endemic for leprosy and Chagas disease in the interior of Bahia proved to be fragmented in the territories. For these diseases, the distance between surveillance and health care actions is reinforced, including in training processes. The importance of innovative permanent and integrated education actions is reiterated to actually promote changes in practices.

RESUMO OBJETIVO Caracterizar conhecimentos, práticas e experiência profissional de agentes comunitários de saúde (ACS) e agentes de controle de endemias (ACE) sobre hanseníase e doença de Chagas (DC), durante participação em oficina de formação integrada no projeto IntegraDTNs-Bahia. MÉTODOS Estudo de caso descritivo e exploratório, envolvendo comunitários de saúde e agentes de controle de endemias, participantes de oficina de formação sobre o papel compartilhado desses profissionais no processo de vigilância e atenção à saúde. Projeto desenvolvido nos municípios de Anagé, Tremedal e Vitória da Conquista, no Sudoeste do Estado da Bahia, 2019-2020. Aplicou-se instrumento específico prévio com questões relativas a conhecimentos e práticas de vigilância e atenção para hanseníase e doença de Chagas. Análise descritiva dos dados, além de consolidação da análise léxica. RESULTADOS Do total de 135 participantes (107 ACS e 28 ACE), 80,7% deles atuam há pelo menos 12 anos, sem participação prévia em processos de formação conjunta. Apenas 17,9% dos agentes de controle de endemias relataram ter participado de capacitações sobre hanseníase e nenhum informou desenvolver ações específicas de controle da doença. Para a doença de Chagas, 36,4% dos agentes comunitários de saúde participaram de capacitações há mais de uma década, enquanto para 60,7% dos agentes de controle de endemias a última capacitação foi realizada nos últimos cinco anos. O desenvolvimento de ações educativas para a doença de Chagas foi mais frequente para agentes de controle de endemias (64,3%). Quando perguntados sobre formas de reconhecimento das doenças, a palavra "manchas na pele" foi a mais relatada (38 vezes) para hanseníase e, para a doença de Chagas, a palavra "não sei" (17 vezes). CONCLUSÃO Os processos de atuação de agentes comunitários de saúde e agentes de controle de endemias em realidades endêmicas para hanseníase e doença de Chagas no interior da Bahia revelaram-se desintegrados nos territórios. Para essas doenças, reforça-se o distanciamento entre ações de vigilância e de atenção à saúde, inclusive nos processos de capacitação. Reitera-se a importância de ações inovadoras de educação permanentes e integradas para promover de fato mudanças nas práticas.

Chronic Chagas cardiomyopathy: characterization of cases and possibilities of action in primary healthcare / Cardiomiopatia chagásica crônica: caracterização de casos e possibilidades para ação na atenção primária à saúde / Miocardiopatía chagásica crónica: caracterización de los casos y posibilidades de actuación de la atención primaria de salud

Despite the drastic decrease in the incidence of Chagas disease in Brazil, past cases still greatly impact health services in the country. Thus, this study aimed to characterize Chagas disease cases regarding their cardiac staging and death prognosis and, based on that, to propose primary healthcare (PHC) case follow-ups. This is a cross-sectional study based on secondary data from the medical records of patients with chronic Chagas cardiomyopathy (CCC). A logistic regression was applied to estimate crude and adjusted odds ratios (OR). A total of 433 medical records were evaluated. More severe CCC cases were associated with a greater number of hospitalizations (OR = 3.41; 95%CI: 1.59-7.30) and longer hospitalization (OR = 3.15; 95%CI: 1.79-5.53). Cases with a higher risk of death were associated with a higher number of hospitalizations (OR = 1.92; 95%CI: 1.09-3.37), longer hospital stays (OR = 2.04; 95%CI: 1.30-3.18), and visits to the outpatient clinic (OR = 2.18; 95%CI: 1.39-3.41) and the emergency department of the assessed hospital (OR = 3.12; 95%CI: 1.27-7.66). Analyzing the medical records at two moments, 72.9% of the cases remained in the stages in which they were initially evaluated. Overall, 44.4% of cases were classified as mild to moderate risk of death and 68.3% as low ones. The cases classified in the most severe stages of CCC and with high or intermediate risk of death were associated with greater hospital dependence. However, most cases were classified as milder forms of the disease, with a low risk of death and clinical stability. These findings aim to promote the role of PHC as a protagonist in the longitudinal follow-up of CCC cases in Brazil.

Apesar da diminuição importante na incidência da doença de Chagas no Brasil, as infecções ocorridas no passado ainda têm um impacto grande sobre os serviços de saúde no país. Portanto, o estudo buscou caracterizar os casos de doença de Chagas quanto ao estadiamento cardíaco e prognóstico de morte, e com base nisso, propor o seguimento dos casos na atenção primária à saúde (APS). O estudo transversal usou dados secundários dos prontuários de pacientes com cardiomiopatia chagásica crônica (CCC). Foi aplicada a regressão logística para estimar os odds ratios (OR) brutos e ajustados. Foram avaliados 433 prontuários médicos. Casos mais graves de CCC estavam associados com número maior de hospitalizações (OR = 3,41; IC95%: 1,59-7,30) e tempo de internação (OR = 3,15; IC95%: 1,79-5,53). Os casos com risco maior de morte estavam associados com número maior de hospitalizações (OR = 1,92; IC95%: 1,09-3,37), tempo de internação (OR = 2,04; IC95%: 1,30-3,18) e visitas aos ambulatórios (OR = 2,18; IC95%: 1,39-3,41) e serviços de emergência (OR = 3,12; IC95%: 1,27-7,66). Ao analisar os prontuários em dois momentos, 72,9% dos casos permaneceram nos estágios inicialmente avaliados. No total, 44,4% dos casos foram classificados como formas leves a moderadas e 68,3% como risco baixo de morte. Os casos classificados nos estágios mais graves de CCC e com risco de morte alto ou intermediário estavam associados com maior dependência hospitalar. Entretanto, a maioria dos casos foram classificados como formas mais leves da doença, clinicamente estáveis e com baixo risco de morte. Os achados apoiam a promoção do papel da APS como protagonista no seguimento longitudinal dos casos de CCC no Brasil.

A pesar de la drástica disminución de la incidencia de la enfermedad de Chagas en Brasil, los casos infectados en el pasado siguen teniendo un gran impacto en los servicios de salud del país. Por lo tanto, este estudio tuvo como objetivo caracterizar los casos de enfermedad de Chagas en lo que se refiere al estadio cardíaco y al pronóstico de muerte y, con base en eso, proponer el seguimiento de los casos por parte de la atención primaria de salud (APS). Se trata de un estudio transversal basado en datos secundarios de las historias clínicas de los pacientes con miocardiopatía chagásica crónica (MCC). Se aplicó la regresión logística para estimar las odds ratio (OR) crudas y ajustadas. Se evaluaron 433 historias clínicas. Los casos de MCC más graves se asociaron a un mayor número de hospitalizaciones (OR = 3,41; IC95%: 1,59-7,30) y días de hospitalización (OR = 3,15; IC95%: 1,79-5,53). Los casos con mayor riesgo de muerte se asociaron a un mayor número de hospitalizaciones (OR = 1,92; IC95%: 1,09-3,37), días de hospitalización (OR = 2,04; IC95%: 1,30-3,18), y las visitas a los ambulatorios (OR = 2,18; IC95%: 1,39-3,41) y al servicio de urgencias (OR = 3,12; IC95%: 1,27-7,66). Analizando las historias clínicas en dos momentos, el 72,9% de los casos permanecieron en los estadios en los que fueron evaluados inicialmente. En general, el 44,4% de los casos fueron clasificados como formas leves o moderadas y el 68,3% como de bajo riesgo de muerte. Los casos clasificados en los estadios más graves de la MCC y con riesgo de muerte alto o intermedio se asociaron a una mayor dependencia hospitalaria. Sin embargo, la mayoría de los casos fueron clasificados como formas más leves de la enfermedad, con bajo riesgo de muerte y clínicamente estables. Estos resultados pretenden promover el papel de la APS como protagonista en el seguimiento longitudinal de los casos de MCC en Brasil.

Abstract Objetive To analyze temporal trends and spatial patterns of mortality due to neglected tropical diseases (NTDs) in Piauí, Brazil, 2001-2018. Methods This was a mixed ecological study, with risk ratio (RR) calculation, spatiotemporal trend analysis, Poisson joinpoint regression, using data from the Mortality Information System. Results There were 2,609 deaths due to NTDs in the period (4.60/100,000 inhabitants), 55.2% were due to Chagas' disease. There was a higher risk of death in male (RR=1.76; 95%CI 1.25;2.46), being aged ≥60 years (RR=40.71; 95%CI 10.01;165.53), municipalities with medium vulnerability social (RR=1.76; 95%CI 1.09;2.84), smaller population size (RR=1.99; 95%CI 1.28;3.10) and the Cerrados macro-region (RR=4.51; 95%CI 2.51;8.11). There was an upward trend in mortality rates from 2001-2008 and a falling trend from 2009-2018. Conclusion Mortality due to NTDs in Piauí remains high, particularly due to Chagas' disease, among groups with greater vulnerability, with concentration of higher rates in the southwest of the Semiarid macro-region and the northeast and south of the Cerrados macro-region.

Seroprevalence of Chagas disease in Southern Brazilian cardiac patients and their knowledge about the parasitosis and vectors / Soroprevalência da doença de Chagas em pacientes cardíacos do sul do Brasil e seu conhecimento sobre a parasitose e vetores

Abstract Chagas disease (CD) is considered a typical low-income population sickness of the developing countries in Latin America. Given the historical relevance of CD in individuals in southern Rio Grande do Sul (RS) State, Brazil, the aim of this study was to identify the knowledge of the CD and its vectors by cardiac patients, and the prevalence of anti-T cruzi antibodies in these individuals in Pelotas, city located in Rio Grande do Sul (RS) state, Brazil. The subjects with cardiac disease were submitted to a semi-structured questionnaire as well as two serological tests in order to detect anti-T. cruzi IgG antibodies. Of the individuals that born in municipalities showing the highest triatomine infestation rates in recent decades, 81.8% were able to recognize the vector insect (p = 0.0042; OR = 5.9), and 83.3% reported either themselves or someone in their families to have CD (p = 0.043, OR = 5.2). Of the 54 patients submitted to serological analysis, only 01 patient (1.9%) was positive for anti-T. cruzi antibodies, a 55 year old man from the rural area of Canguçu county. This study provides support for the evaluation to be extended to other cardiology centers, given the importance of Chagas disease in Brazil.

Resumo A doença de Chagas (DC) é considerada uma doença típica da população de baixa renda dos países em desenvolvimento da América Latina. Dada a relevância histórica da DC em indivíduos do sul do Estado do Rio Grande do Sul (RS), o objetivo deste estudo foi identificar o conhecimento da doença de Chagas (DC) e seus vetores em pacientes cardíacos, e a prevalência de anticorpos anti-T cruzi nesses indivíduos, em Pelotas, cidade localizada no Rio Grande do Sul (RS), Brasil. Os pacientes cardiopatas foram submetidos a um questionário semiestruturado, e também a dois testes sorológicos para detecção de anticorpos anti-T. cruzi IgG. Dos indivíduos que nasceram em municípios com as maiores taxas de infestação por triatomíneos nas últimas décadas, 81,8% foram capazes de reconhecer o inseto vetor (p = 0,0042; OR = 5,9), e 83,3% relataram que eles próprios ou alguém em suas famílias tem DC (p = 0,043, OR = 5,2). Dos 54 pacientes submetidos à análise sorológica, apenas 01 paciente (1,9%) foi positivo para anticorpos anti-T.cruzi, um homem de 55 anos da área rural do município de Canguçu. Este estudo fornece subsídios para que a avaliação seja estendida a outros centros de cardiologia, devido à importância da doença de Chagas no Brasil.

Validation of a documentary on Chagas disease by a population living in an endemic area / Validação de um documentário sobre a doença de Chagas por uma população de área endêmica

Abstract Educational interventions may trigger actions that contribute to prevent parasitic diseases, such as Chagas disease (CD). This study aimed at investigating the impact of an instructional video named "Documentary on Chagas Disease" on knowledge about CD and its vectors displayed by a population that lives in an endemic area in Brazil, so as to validate it as an educational tool. The video was shown to 226 subjects, divided into two groups. Group 1 was composed of users of Basic Health Units (BHU) in Pelotas and Pinheiro Machado, cities located in Rio Grande do Sul (RS) state, Brazil, where CD is endemic. Group 2 consisted of students who attend three public schools located in the rural area in Pinheiro Machado, RS. Two questionnaires with questions about their knowledge about triatomines and CD were applied, before and after the documentary was shown. After the video was shown, there was significant increase in individuals' knowledge (in both groups) about "kissing bugs", their notification, the disease and its prevention. Besides, watchers considered that the quality of the material was satisfactory. Since the "Documentary on CD" can be easily accessed on the internet and was effective in teaching the population that lives in endemic areas, its use should be encouraged in places and meetings connected to health that aim at fighting against triatominae and at exposing an updated view of CD.

Resumo Intervenções educacionais podem desencadear ações que contribuam para a prevenção de doenças parasitárias, como a doença de Chagas (DC). Este estudo teve como objetivo investigar o impacto de um vídeo instrucional denominado "Documentário Doença de Chagas" no conhecimento sobre DC e seus vetores exibidos a uma população que vive em área endêmica no Brasil, para validá-lo como uma ferramenta educacional. O vídeo foi exibido para 226 indivíduos, divididos em dois grupos. O grupo 1 foi composto por usuários das Unidades Básicas de Saúde (UBS) de Pelotas e Pinheiro Machado, cidades do estado do Rio Grande do Sul (RS), Brasil, onde a DC é endêmica. O grupo 2 foi formado por estudantes que frequentam três escolas públicas localizadas na zona rural de Pinheiro Machado, RS. Dois questionários com perguntas sobre conhecimentos sobre triatomíneos e DC foram aplicados, antes e depois da exibição do documentário. Após a exibição do vídeo, houve um aumento significativo no conhecimento dos indivíduos (em ambos os grupos) sobre "triatomíneos", sua notificação, a doença e sua prevenção. Além disso, os observadores consideraram que a qualidade do material era satisfatória. Como o "Documentário DC" pode ser facilmente acessado na Internet e ser eficaz no ensino à população que vive em áreas endêmicas, seu uso deve ser incentivado em locais e reuniões relacionadas à saúde, que visam combater os triatomíneos e exibir uma informação atualizada sobre a DC.

Diseño y validación de cuestionario de conocimientos, actitudes y prácticas de la enfermedad de Chagas / Design and validation of the survey of knowledge, attitudes and practices of Chagas disease

La enfermedad de Chagas es considerada una afección desatendida a nivel mundial que afecta principalmente a la población de escasos recursos en Latinoamérica, con aproximadamente 10 millones de personas afectadas. Se estima que en Ecuador más de 200000 personas son seropositivas para T. cruzi y 4.400 adquieren la infección anualmente. Se han realizado estudios en zonas endémicas como Loja, Manabí, Guayas y El Oro, las cuales constituyen el hábitat de cinco especies de triatómicos, responsables de la transmisión vectorial de la enfermedad, no obstante, se requiere información epidemiológica actualizada en áreas consideradas prioritarias. Es por ello, que se realizó un estudio descriptivo transversal para diseñar y validar un cuestionario de conocimientos, actitudes y prácticas de la enfermedad de Chagas en las 5 áreas prioritarias en Ecuador. Se diseñó un cuestionario inicial de 36 ítems, empleado para un estudio piloto con 5 expertos claves que validaron dicho instrumento, Para evaluar la validez de contenido se empleó la V de Aiken (0,82) y la validez del constructo fue evaluada a través del análisis factorial exploratorio, del cual se obtuvieron 3 dimensiones; ´ mientras que la prueba de alfa de Cronbach (>0,7) demostró la consistencia interna del instrumento. La versión final del cuestionario contentiva de 31 ítems fue aplicada a 20 participantes con características epidemiológicas diferentes de cada área prioritaria, demostrando que el mismo reúne todas las condiciones de validación y confiabilidad y puede ser aplicado en otros estudios epidemiológicos relacionados con la enfermedad de Chagas(AU)

Chagas disease is considered a neglected condition worldwide which mainly affects the poor population in Latin America, with approximately 10 million people affected. It is estimated that in Ecuador more than 200,000 people are seropositive for T. cruzi and 4,400 acquire the infection annually. Studies have been carried out in endemic areas such as Loja, Manabí, Guayas and El Oro, which constitute the habitat of five species of triatomics, responsible for the vector transmission of the disease, however, updated epidemiological information is required in areas considered priority. For this reason, a cross-sectional descriptive study was carried out to design and validate a questionnaire on knowledge, attitudes and practices of Chagas disease in the 5 priority areas in Ecuador. An initial questionnaire of 36 items was designed, used for a pilot study with 5 key experts who validated said instrument. To evaluate the content validity, Aiken's V (0.82) was used and the validity of the construct was evaluated through the exploratory factor analysis, from which 3 dimensions were obtained; While the Cronbach's alpha test (> 0.7) demonstrated the internal consistency of the instrument. The final version of the questionnaire containing 31 items was applied to 20 participants with different epidemiological characteristics from each priority area, showing that it meets all the validation and reliability conditions and can be applied in other epidemiological studies related to Chagas disease(AU)

Estrategias para la detección precoz y vigilancia entomológica del mal de Chagas en Ecuador: entre el olvido y la reemergencia / Strategies for the early detection and entomological surveillance of Chagas disease in Ecuador: between oblivion and reemergence

La enfermedad de Chagas (EC) es originada por el protozoario Trypanosoma cruzi, constituyendo un problema social y de salud pública en las Américas. En los últimos años en Ecuador existe un repunte sostenido de casos de EC y la Organización Mundial de la Salud (OMS) en el año 2020, enfatizó la necesidad de aplicar estrategias para control de enfermedades tropicales desatendidas 2021-2030, incorporando lineamientos relacionados con la EC. Se realizó un estudio descriptivo con el fin de verificar la adopción por parte del estado ecuatoriano de estrategias para detección precoz y vigilancia entomológica de EC, de acuerdo a la hoja de ruta propuesta por la OMS. Para ello, se consultó la epidemiología de EC durante el período 2013-2020, se revisó lineamientos y estrategias para eliminación de enfermedades desatendidas, se realizó análisis epidemiológico de EC y se categorizaron las estrategias para detección precoz de EC. Se observó un incremento de casos de EC crónica respecto a la EC aguda (n=432; 78,26% vs 21,74%). Además, el estado ecuatoriano aplica lineamientos de interrupción de transmisión vectorial domiciliaria y transfusional, eliminación de EC congénita y cobertura de tratamiento antiparasitario de la población en riesgo, no obstante, no se aplican medidas para la interrupción de transmisión por trasplante de órganos(AU)

Chagas disease (CD) is caused by the protozoan Trypanosoma cruzi, constituting a social and public health problem in the Americas. In recent years in Ecuador there has been a sustained rebound in CD cases and the World Health Organization (WHO) in 2020, emphasized the need to apply strategies for the control of neglected tropical diseases 2021-2030, incorporating guidelines related to the EC. A descriptive study was carried out in order to verify the adoption by the Ecuadorian state of strategies for early detection and entomological surveillance of CD, according to the roadmap proposed by the WHO. To do this, the epidemiology of CD was consulted during the 2013-2020 period, guidelines and strategies for elimination of neglected diseases were reviewed, epidemiological analysis of CD was carried out, and strategies for early detection of CD were categorized. An increase in chronic CD cases was observed compared to acute CD (n = 432; 78.26% vs 21.74%). In addition, the Ecuadorian state applies guidelines for the interruption of domiciliary and transfusion vector transmission, elimination of congenital CD and coverage of antiparasitic treatment of the population at risk, however, no measures are applied for the interruption of transmission by organ transplantation. In this sense, it is necessary to implement strategies and protocols, aimed at detecting parasitosis in transplanted patients, as well as training communities around the interruption of vector transmission of CD(AU)

Infección por trypanosoma cruzi y bloqueo cardíaco del nodo auriculoventricular en el salvador / Trypanosoma cruzi infection and atrioventricular-nodal heart block in El Salvador

Resumen La enfermedad de Chagas es endémica en América Latina y sigue siendo un problema regional a pesar de que su frecuencia ha disminuido gracias a importantes avances en salud ambiental. Para determinar su frecuencia en pacientes con enfermedades miocárdicas de El Salvador, se llevó a cabo una in vestigación observacional retrospectiva en nuestro hospital que es un centro de referencia de nivel nacional. Se revisó el registro del Laboratorio de Chagas en el período 2013-2015 para conocer cuántos individuos internados en la Unidad Cardiológica eran positivos por serología para infección chagásica y cuáles fueron sus diagnósticos. Se realizó un total de 1472 pruebas a pacientes individuales durante los 36 meses del período de estudio. De los 557 pacientes con serología positiva para Chagas, 97 (17.4%) fueron eventualmente hospitalizados en la Unidad Cardiológica. A su vez, estos 97 pacientes representaron el 33.7% de los 288 pacientes con cardiopatías. Entre los 97 con cardiopatía chagásica, 40 (41.2%) cumplieron criterios para colocación de marcapaso permanente, mientras que solo 13 de 191 (6.8%) enfermos con cardiopatías no chagásicas cumplieron esos criterios. La frecuencia de bloqueos auriculoventriculares asociados a infección por Trypanosoma cruzi resultó mucho mayor que las publicadas en estudios previos realizados en Sudamérica.

Abstract Chagas disease is endemic in Latin America and remains a regional problem despite improvements in en vironmental health conditions that have helped to control its transmission. To know more about its prevalence in heart disease patients, we carried out a survey in our national (El Salvador) reference hospital. We reviewed the Chagas Lab´s records 2013-2015 to find out how many of the patients admitted to the Hospital´s Heart Unit were serologically positives for Trypanosoma cruzi infection and which the associated diagnoses were. A total of 1472 patients were tested along the 36-month study period. Out of 557 (37.8%) patients with positive serology for Chagas infection, 97 (17.4%) were eventually admitted to the Heart Unit. Among these 97 Chagas infected patients with heart disease, 40 (41.2%) met the criteria for permanent pacemaker placement, while only 13 of 191 (6.8%) patients with non-chagasic heart disease met these criteria. The frequency of heart atrioventricular block associated with Trypanosoma cruzi infection was higher than frequencies reported in South American studies.

Chagas Disease in the Western Brazilian Amazon: Epidemiological Overview from 2007 to 2018 / Doença de Chagas na Amazônia Ocidental Brasileira: panorama epidemiológico no período de 2007 a 2018

INTRODUCTION: Chagas disease (CD) is a disease caused by the protozoan flagellates of the Kinetoplastid order Trypanosoma cruzi. Approximately 8,000,000 people are infected worldwide, mainly in Latin America, causing disabilities and more than 10,000 deaths per year OBJECTIVE: This study aimed to describe the epidemiological panorama of CD in the Western Brazilian Amazon from 2007 to 2018. METHODS: In this ecological study, secondary data regarding the confirmed cases of T. cruzi infection in the states of Acre, Amazonas, Rondônia, and Roraima were collected from the Single Health System Notification Information System of the Department of Informatics of the Single Health System and were analyzed. The data were used to characterize the epidemiological profile of T. cruzi infection and to determine the frequency of infection in Western Amazonia. RESULTS: A total of 184 cases of CD were reported in Western Amazonia, and the highest number of cases was reported in the states of Amazonas and Acre. CONCLUSION: The epidemiological panorama of the Western Brazilian Amazon from 2007 to 2018 includes a greater number of cases of T. cruzi infection in men aged 20-39 years and those living in rural areas. Oral transmission was prevalent in the region during the study, and the highest number of cases was reported in the months of April and December. Epidemiological data are an important resource for understanding the dynamics of CD and the main aspects related to the health-disease process.

Introducción: La Enfermedad de Chagas es una zoonosis parasitaria causada porTrypanosoma cruzi, un protozoario que se transmite principalmente de manera vectorial al ser humano. Estudios de campo predicen que un tercio de un estimado de 18 millones de personas infectadas en Latinoamérica morirán de Enfermedad de Chagas. Objetivo: El objetivo de este estudio fue determinar la seroprevalencia de la infección por Trypanosoma cruzi y factores asociados en población del municipio de Cumaral, Meta, Colombia. Material y Métodos: Se realizó un estudio descriptivo de tipo transversal, en el cual se recolectaron sueros de toda persona habitante del municipio de Cumaral por más de seis meses y que habitara en área urbana o rural. Se utilizó el método de ELISA de extractos totales (Primera prueba) para la detección de IgG antiTripanosoma cruzy; a los positivos se les realizó prueba confirmatoria por ELISA recombinante; los resultados dudosos fueron enviados al Instituto Nacional de Salud para su confirmación mediante la inmunofluorescencia indirecta. Para el análisis de la información se utilizó el paquete estadístico Prism versión 8.2.1 para MacOS. Resultados: En la tamización de la prueba para Chagas del presente estudio, resultó positivo 2,7 por ciento de los evaluados; al contrastar los sujetos con resultado positivo con los negativos, se observaron diferencias en la edad, la escolaridad y el material de las paredes de sus viviendas. Conclusiones: Los resultados proporcionan información útil de condiciones de vivienda y seroprevalencia de la enfermedad, que ayudan a evaluar la efectividad del acuerdo que facilita y fortalece el acceso al diagnóstico y tratamiento de la enfermedad(AU)

Introduction: Chagas disease is a parasitic zoonosis caused byTrypanosoma cruzi, a vector-born protozoan that is transmitted to humans. Field studies predict that one-third of around 18 millionT cruzi-infected humans will die of Chagas disease in Latin America. Objective: To determine the seroprevalence of the infection with Trypanosoma cruzi and to identify some risk factors associated with this condition in Cumaral, Meta, Colombia. Material and Methods: A descriptive, cross-sectional study was conducted. Blood samples were collected from subjects that had been living in urban and rural areas of Cumaral municipality for more than six months. An ELISA-IgG method with total extracts (first test) was used for the detection of Trypanosoma cruzy IgG. A recombinant-based ELISA was performed as a confirmatory test. Doubtful results were sent to the National Institute for Health for confirmation by indirect immunofluorescence assay. Prism 8 for MacOS (version 8.2.1) was used for statistical analysis. Results: In the screening for Chagas disease, 2,7 percent of all the cases tested were positive. When comparingsubjects with positiveandnegative results, differences between age, scholarship and materials used in the construction of house walls were evidenced. Conclusions: The results provide useful information about housing conditions and seroprevalence of the disease that help to evaluate the effectiveness of the arrangement that provides and strengthens the access to the diagnosis and treatment of the disease(AU)

Occurrence of Panstrongylus megistus (Burmeister, 1835) in an area under entomological surveillance in the Southeast Region of Brazil

Abstract INTRODUCTION: Panstrongylus megistus is the main triatomine involved in the human transmission of Trypanosoma cruzi in Minas Gerais, Brazil. We analyzed the occurrence of triatomines in the Itaúna micro-regions for healthcare. METHODS: Data were collected as part of routine entomological surveillance activities, including the species identity, capture site, developmental stage, and trypanosome infection. RESULTS: In total, 503 specimens from five species were captured (495 P. megistus). Adults were mainly captured by residents inside their homes, whereas nymphs were mostly captured by public health professionals outside. CONCLUSIONS: The epidemiologically important triatomine, P. megistus, continues to persist in our study region.

Do the new triatomine species pose new challenges or strategies for monitoring Chagas disease? An overview from 1979-2021

Chagas disease persists as one of the most important, and yet most neglected, diseases in the world, and several changes in its epidemiological aspects have been recorded since its discovery. Currently, some of the most relevant changes are related to: (i) the reduction in the incidence of the endemic due to the control of the most important vectors, Triatoma infestans and Rhodnius prolixus, in many countries; (ii) the migration of human populations spreading cases of the disease throughout the world, from endemic to non-endemic areas, transforming Chagas disease into a global threat; and (iii) new acute cases and deaths caused by oral transmission, especially in the north of Brazil. Despite the reduction in the number of cases, new challenges need to be responded to, including monitoring and control activities aiming to prevent house infestation by the secondary vectors from occurring. In 1979, Lent & Wygodzinsky(1) published the most complete review of the subfamily Triatominae, encompassing 111 recognised species in the taxon. Forty-two years later, 46 new species and one subspecies have been described or revalidated. Here we summarise the new species and contextualise them regarding their ecology, epidemiologic importance, and the obstacles they pose to the control of Chagas disease around the world.

Temporal changes in the clinical-epidemiological profile of patients with Chagas disease at a referral center in Brazil

Abstract INTRODUCTION We aimed to describe the sociodemographic, epidemiological, and clinical characteristics of patients with chronic Chagas disease (CD) at an infectious disease referral center. Changes in patient profiles over time were also evaluated. METHODS This retrospective study included patients with CD from November 1986-December 2019. All patients underwent an evaluation protocol that included sociodemographic profile; epidemiological history; anamnesis; and physical, cardiologic, and digestive examinations. Trend differences for each 5-year period from 1986 to 2019 were tested using a nonparametric trend test for continuous and generalized linear models with binomial distribution for categorical variables. RESULTS A total of 2,168 patients (52.2% women) were included, with a mean age of 47.8 years old. White patients with low levels of education predominated. The reported transmission mode was vectorial in 90.2% of cases. The majority came from areas with a high prevalence (52.2%) and morbidity (67.8%) of CD. The most common clinical presentation was the indeterminate form (44.9%). The number of patients referred gradually decreased and the age at admission increased during the study period, as did the patients' levels of education. CONCLUSIONS The clinical profile of CD is characterized by a predominance of the indeterminate form of the disease. Regarding the patients who were followed up at the referral center, there was a progressive increase in the mean age and a concomitant decrease in the number of new patients. This reflects the successful control of vector and transfusion transmission in Brazil as well as the aging population of patients with CD.
