Abstract: En | Text: En | PDF: En

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. There is an urgent need for safe, effective, and accessible new treatments since the currently approved drugs have serious limitations. Drug development for Chagas disease has historically been hampered by the complexity of the disease, critical knowledge gaps, and lack of coordinated R&D efforts. This review covers some of the translational challenges associated with the progression of new chemical entities from preclinical to clinical phases of development, and discusses how recent technological advances might allow the research community to answer key questions relevant to the disease and to overcome hurdles in R&D for Chagas disease. cruzi safe effective limitations gaps RD R D efforts

Abstract: En | Text: En | PDF: En

Chagas disease (CD) still imposes a heavy burden on most Latin American countries. Vector-borne and mother-to-child transmission cause several thousand new infections per year, and at least 5 million people carry Trypanosoma cruzi. Access to diagnosis and medical care, however, is far from universal. Starting in the 1990s, CD-endemic countries and the Pan American Health Organization-World Health Organization (PAHO-WHO) launched a series of multinational initiatives for CD control-surveillance. An overview of the initiatives’ aims, achievements, and challenges reveals some key common themes that we discuss here in the context of the WHO 2030 goals for CD. Transmission of T. cruzi via blood transfusion and organ transplantation is effectively under control. T. cruzi, however, is a zoonotic pathogen with 100+ vector species widely spread across the Americas; interrupting vector-borne transmission seems therefore unfeasible. Stronger surveillance systems are, and will continue to be, needed to monitor and control CD. Prevention of vertical transmission demands boosting current efforts to screen pregnant and childbearing-aged women. Finally, integral patient care is a critical unmet need in most countries. The decades-long experience of the initiatives, in sum, hints at the practical impossibility of interrupting vector-borne T. cruzi transmission in the Americas. The concept of disease control seems to provide a more realistic description of what can in effect be achieved by 2030.

Abstract: En

As the global COVID-19 pandemic advances, it increasingly impacts the vulnerable populations who already bear a heavy burden of neglected tropical diseases. Chagas disease (CD), a neglected parasitic infection, is of particular concern because of its potential to cause cardiac, gastrointestinal, and other complications which could increase susceptibility to COVID-19. The over one million people worldwide with chronic Chagas cardiomyopathy require special consideration because of COVID-19’s potential impact on the heart, yet the pandemic also affects treatment provision to people with acute or chronic indeterminate CD. In this document, a follow-up to the WHF-IASC Roadmap on CD, we assess the implications of coinfection with SARS-CoV-2 and Trypanosoma cruzi, the etiological agent of CD. Based on the limited evidence available, we provide preliminary guidance for testing, treatment, and management of patients affected by both diseases, while highlighting emerging healthcare access challenges and future research needs.

Abstract INTRODUCTION: Congenital transmission (CT) of Trypanosoma cruzi has led to globalization of Chagas disease and its growing relevance as a public health problem. Although the occurrence of CT has been associated with several factors, its mechanisms are still unknown. This study aimed to analyze the geographical and familiar variables of mothers and their association with CT of Chagas disease in a population living in non-endemic areas of Argentina for the last decades. METHODS: We developed a retrospective cohort study in a sample of 2120 mother-child pairs who attended three reference centers in the cities of Buenos Aires, Santa Fe, and Salta between 2002 and 2015. RESULTS: The highest CT rates were observed in children born to Argentinean mothers (10.7%) and in children born to mothers from Buenos Aires (11.7%). Considering the areas of origin of the mothers, those from areas of null-low risk for vector-borne infection had higher CT rates than those from areas of medium-high risk (11.1% vs 8.2%). We also observed a significant intra-familiar “cluster effect,” with CT rates of 35.9% in children with an infected sibling, compared to 8.2% in children without infected siblings (RR=4.4 95% CI 2.3-8.4). CONCLUSIONS: The associations observed suggest a higher CT rate in children born to mothers who acquired the infection congenitally, with familiar antecedents, and from areas without the presence of vectors. These observations are considered new epidemiological evidence about Chagas disease in a contemporary urban population, which may contribute to the study of CT and may also be an interesting finding for healthcare professionals.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

In Argentina, around 1500 children are born each year with Trypanosoma cruzi infection. Mother-to-child transmission is the main source of new cases of Chagas disease and of its occurrence in non-endemic areas. Our objective was to survey the information available on congenital T. cruzi infection, to analyze its evolution and its relation with the index of maternal infection and the risk for vector-borne infection by province of Argentina. Data concerning the public health sector for the period 1997-2014 were retrieved from national and local records. An increase in the number and proportion of pregnant women examined for Chagas was observed, reaching 60.3% coverage in 2014. The prevalence of maternal infection dropped from 9.0% to 2.6%. The control of newborns from infected women was highly variable (23.3%-93.6%), and data quality was deficient, varying amply by province and year. The rate of congenital infection had an irregular evolution and its national average fluctuated between 1.9 and 8.2%. An association was observed between the risk for vector-borne infection and the prevalence of maternal infection by province (Wilcoxon test p = 0.017). The rate of congenital transmission by province was neither associated with the rate of maternal infection (linear regression p = 0.686) nor with the risk for vectorial infection (Kruskal-Wallis test p = 0.3154). The available data show insufficient control of children born from infected mothers, as well as deficient recording of these procedures. Both aspects must be improved to achieve better epidemiological information and to enable timely access of infected children to treatment.

En Argentina nacen alrededor de 1500 niños por año con infección por Trypanosoma cruzi. La transmisión vertical es la principal vía de generación de nuevos casos de Chagas, y de su presencia en zonas no endémicas. Nuestro objetivo fue relevar datos disponibles sobre infección congénita por T. cruzi, analizar su evolución y relación con indicadores de prevalencia materna y riesgo vectorial por regiones de Argentina. Se investigaron fuentes oficiales y bibliografía científica. Se obtuvieron datos nacionales y provinciales del período 1997-2014 del subsector público de salud. Se observó un aumento de embarazadas controladas, que alcanzó una cobertura del 60.3% en 2014. La prevalencia de infección materna descendió de 9.0% a 2.6%. El control en hijos de mujeres infectadas fue variable (entre 23.3% y 93.6% de los niños en riesgo) y la calidad del dato fue deficiente según provincia y año. La tasa de transmisión congénita tuvo una evolución irregular y, según un indicador corregido, la tasa media nacional fluctuó entre 1.9 y 8.2%. Se observó asociación entre la prevalencia materna y el riesgo vectorial en las provincias (test Wilcoxon p = 0.017). La tasa de transmisión congénita provincial no mostró relación con la tasa de infección materna (regresión lineal p = 0.686) ni con el nivel de riesgo vectorial (test Kruskal-Wallis p = 0.3154). Los datos disponibles muestran una deficiencia en los controles de hijos de madres infectadas y de su notificación en el período analizado. Deben mejorar ambos aspectos para obtener información epidemiológica fiable y permitir el acceso oportuno de los niños infectados al tratamiento.

Resumen La transmisión congénita de la enfermedad de Chagas ha sido poco estudiada en Colombia y existen pocos procedimientos rutinarios en el sistema de salud para el manejo de esta enfermedad. Por ello se desarrolló un consenso de expertos dirigido a generar recomendaciones de diagnóstico y tratamiento de Chagas con- génito y orientación a mujeres en edad fértil. Con ese propósito se realizó una búsqueda extensiva de la literatura, empleando una combinación de términos Mes (Chagas, Chagas congénito, prevención, control, diagnóstico, tratamiento y embarazo) para reflejar el estado del arte en cada tema de interés. Después de ello, se leyeron los resúmenes y aquellos seleccionados para análisis del texto completo. La literatura relevante se sintetizo, clasifico y organizo en tablas y se presentó al panel de expertos, el cual estaba constituido por 30 profesionales en diferentes áreas. Mediante la metodología Delphi se realizaron 2 rondas de cuestionarios virtuales y una reunión presencial en los cuales se evaluaron los niveles de acuerdo entre los participantes. Los puntos con falta de consenso durante las 2 rondas virtuales se expusieron durante las mesas de discusión en la ronda presencial. La evidencia utilizada se adaptó a las particularidades nacionales según el caso y se aprobó el contenido del documento final. Se propone que estas recomendaciones sean usadas por profesionales de la salud en Colombia.

Abstract Congenital transmission of Chagas disease has not been extensively studied in Colombia, and there are no standardized processes in the health system regarding the specific diagnosis, treatment and follow-up of this disease. To generate recommendations on congenital Chagas disease and Chagas in women of childbearing age in Colombia, a consensus of experts was developed. An extensive literature search through the Medline database was carried out using the MeSH terms: «Chagas disease/congenital», «prevention and control», «diagnosis», «therapeutics» and «pregnancy». Appropriate abstracts were selected and the full texts were analyzed. The relevant information was synthesized, classified, and organized into tables and figures and was presented to a panel of experts, which was composed of 30 professionals from various fields. Based on the Delphi methodology, three rounds of consultation were conducted. The first and second rounds were based on electronic questionnaires that measured the level of consensus of each question among the participants. The third round was based on a face-to-face discussion focusing on those questions without consensus in the previous consultations. The evidence was adapted to national circumstances on a case-by-case basis, and the content the final document was approved. These recommendations are proposed for use in routine medical practice by health professionals in Colombia.

Visando a aumentar a precisão do diagnóstico, a Organização Mundial da Saúde recomenda executar dois ou mais testes imunoserológicos para o diagnóstico na fase crônica da doença de Chagas. O objetivo deste trabalho foi fazer uma revisão sistemática rápida sobre o desempenho de técnicas imunoserológicas e métodos moleculares na população em geral. Foram identificados 178 estudos dos quais se incluíram nove. Técnicas de ELISA mostraram a maior sensibilidade (82-98%) e especificidade (96-100%). Métodos rápidos apresentaram valores de sensibilidade e especificidade de 88-93% e 97-100%, respectivamente enquanto que os métodos moleculares (PCR) tinham níveis extremamente variáveis de sensibilidade (22-92%) e especificidade (70-100%). Estes resultados mostram que as técnicas de ELISA possuem sensibilidade e especificidade adequadas. A PCR, bem como os métodos rápidos, mostrou grande variabilidade nos resultados, principalmente devido à heterogeneidade das técnicas e profusão de métodos desenvolvidos de modo in house.

In order to increase diagnostic accuracy, the World Health Organization recommends performing two or more immunoserological tests for the diagnosis of Chagas disease in chronic stage. The aim of this work was to make a rapid systematic review of the performance of immunoserological techniques and molecular methods in the general population. A total of 178 studies were identified, nine ofwhich were included. ELISA techniques showed the highest sensitivity (82-98%) and specificity (96-100%). Rapid methods presented values of sensitivity between 88-93% and 97-100% of specificity, while the molecular methods (PCR) showed highly variable levels of sensitivity (22-92%) and specificity (70-100%). These results indicate that ELISA techniques have adequate sensitivity and specificity. PCR, as well as rapid methods, showed great variability in the results, mainly due to the heterogeneity of the techniques and abundance of “in-house” methods.

Abstract: En | Text: En | PDF: En

Chagas disease or American trypanosomiasis is, together with geohelminths, the neglected disease that causes more loss of years of healthy life due to disability in Latin America. Chagas disease, as determined by the factors and determinants, shows that different contexts require different actions, preventing new cases or reducing the burden of disease. Control strategies must combine two general courses of action including prevention of transmission to prevent the occurrence of new cases (these measures are cost effective), as well as opportune diagnosis and treatment of infected individuals in order to prevent the clinical evolution of the disease and to allow them to recuperate their health. All actions should be implemented as fully as possible and with an integrated way, to maximise the impact. Chagas disease cannot be eradicated due because of the demonstrated existence of infected wild triatomines in permanent contact with domestic cycles and it contributes to the occurrence of at least few new cases. However, it is possible to interrupt the transmission ofTrypanosoma cruziin a large territory and to eliminate Chagas disease as a public health problem with a dramatic reduction of burden of the disease.

Abstract: En | Text: En | PDF: En

Congenital infection with Trypanosoma cruzi is a global problem, occurring on average in 5% of children born from chronically infected mothers in endemic areas, with variations depending on the region. This presentation aims to focus on and update epidemiological data, research methods, involved factors, control strategy and possible prevention of congenital infection with T. cruzi. Considering that etiological treatment of the child is always effective if performed before one year of age, the diagnosis of infection in pregnant women and their newborns has to become the standard of care and integrated into the surveillance programs of syphilis and human immunodeficiency virus. In addition to the standard tests, polymerase chain reaction performed on blood of neonates of infected mothers one month after birth might improve the diagnosis of congenital infection. Recent data bring out that its transmission can be prevented through treatment of infected women before they become pregnant. The role of parasite genotypes and host genetic factors in parasite transmission and development of infection in foetuses/neonates has to be more investigated in order to better estimate the risk factors and impact on health of congenital infection with T. cruzi.

In order to generate recommendations on congenital Chagas disease and Chagas in women of childbearing age in Colombia, a consensus of experts was developed. An extensive literature search through the Medline database was carried out using the MeSH terms: " Chagas disease/congenital " , " prevention and control " , " diagnosis " , " therapeutics " and " pregnancy " . Appropriate abstracts were selected and the full texts were analyzed. The relevant information was synthesized, classified, and organized into tables and figures and was presented to a panel of experts, which was composed of 30 professionals from various fields. Based on the Delphi methodology, three rounds of consultation were conducted. The first and second rounds were based on electronic questionnaires that measured the level of consensus of each question among the participants. The third round was based on a face-toface discussion focusing on those questions without consensus in the previous consultations. The evidence was adapted to national circumstances on a case-by-case basis, and the content the final document was approved. These recommendations are proposed for use in routine medical practice by health professionals in Colombia.

O objetivo foi detectar a infecção do Trypanosoma cruzi em 32 crianças nacidas de 16 jovens mulheres cronicamente infectadas e tratadas com benzinadol, em Salta, Argentina. Testes foram feitos para avaliar a eficácia após 14 anos do tratamento. Ao final do seguimento 87.5% das mulheres foram não reativas ao EIA, 62.5% ao IHA e 43.8% ao IFA. 62.5% das mulheres foram não reativas de acordo a 3 ou 2 testes serológicos. Nenhuma criança infectada foi detectada entre os recém-nascidos de mães tratadas antes da gravidez.
