Chronic manifestations of Chagas disease present as disabling and life-threatening conditions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mechanisms underlying Trypanosoma cruzi’s infection and the host-parasit...e interactions that follow, prompt diagnosis and treatment remain a challenge, particularly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence
factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.

Chagas disease is a neglected tropical disease caused by the protozoan parasite Trypanosoma cruzi. It is a significant public health problem, affecting millions of people worldwide. And although it was described 110 years ago, only two old nitroheterocyclic drugs, benznidazole and nifurtimox, are cu...rrently available for the treatment of Chagas disease and both have several limitations. Besides the clear unmet medical need, many challenges preclude the development of new treatments, some of them related to a lack of understanding of the pathophysiology of the disease and parasite-host interactions. New knowledge and tools are becoming available, but the number of new chemical entities progressing through the preclinical pipeline is inadequate. Therefore, it is still uncertain whether safe, effective and accessible new drugs will be available in the near future. The Chagas disease research community must commit to even greater collaboration to ensure that patients eventually benefit from better treatments.

Kinetoplastid parasites have caused human disease for millennia. Significant achievements have been made toward developing new treatments for leishmaniasis (particularly on the Indian subcontinent) and for human African trypanosomiasis (HAT). Moreover, the sustained decrease in the incidence of HAT... has made the prospect of elimination a tantalizing reality. Despite the gains, no new chemical or biological entities to treat kinetoplastid diseases have been registered in more than three decades, and more work is needed to discover safe and effective therapies for patients with Chagas disease and leishmaniasis. Advances in tools for drug discovery and novel insights into the biology of the host−parasite interaction may provide opportunities for accelerated progress. Here, we summarize the output from a gathering of scientists and physicians who met to discuss the current status and future directions in drug discovery for kinetoplastid diseases.

Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical man...ifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%-60%), followed by heart failure (25%-30%) and stroke (10%-15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

El desarrollo, desde 1991, de las Iniciativas Subregionales de Control de la Enfermedad de Chagas, y los avances de conocimiento en materia de diagnóstico y manejo de la infección/enfermedad de Chagas, llevan a la necesidad ética, y operativamente imperiosa, de estructurar el diagnóstico, atenci...ón y tratamiento de esta afección.
Una situación particularmente delicada, preocupante y alarmante, se constituye por la escasa einequitativa disponibilidad de los limitados recursos terapéuticos, actualmente disponibles, para el tratamiento etiológico de Chagas, en la mayor parte de los países endémicos de América.
En esta situación, se propone el desarrollo de la Consulta técnica regional OPS/MSF sobre organización y estructura de la atención médica del enfermo e infectado por Trypanosoma cruzi (enfermedad de Chagas), con los objetivos de:
- definir el alcance y estructura de la atención médica al paciente, tanto en diagnóstico, manejo como tratamiento;
- desarrollar modelos alternativos y optativos de atención, asimilables a las estructurassanitarias de los países;
- delinear la atención del chagásico, según su momento biológico-patológico evolutivo,dentro de los niveles de complejidad de la atención médica;
- establecer consideraciones sobre la atención pediátrica, materno-infantil, transfusional y mayor complejidad;
- definir las necesidades y alcances del diagnóstico de la enfermedad;
- establecer los alcances y facilidades que, dentro de los sistemas de atención, deben poseer estos pacientes;
- definir el panorama total de disponibilidad y accesibilidad de los pacientes al tratamiento etiológico de esta dolencia;
- proyectar conceptos y concepciones marco sobre el costo, impacto y efectividad del
desarrollo de este componente de morbilidad y atención en enfermedad de Chagas; y
- establecer las necesidades de investigación operativa y de gestión para avanzar en el
desarrollo de la atención médica a este grupo de pacientes.
Esta consulta, desarrollada en la ciudad de Montevideo, el 13 y 14 de octubre de 2005, pretende marcar la elaboración de una guía conceptual para comentarla y diseminarla en el año 2006, desde las cinco Iniciativas Intergubernamentales Subregionales de Control de Enfermedad de Chagas.

Chagas disease (American trypanosomiasis) is endemic in 21 countries of the Americas, where control is largely focused on elimination of the domestic insect vectors (Triatominae) coupled with measures to extend and improve the screening of blood donors in order to avoid tranfusional transmission. Th...rough national programmes and multinational initiatives coordinated by WHO-PAHO, much has been accomplished in these domains in terms of reducing transmission. Attention now turns to consolidating the successes in interrupting transmission, and improved treatment for those already infected and those who may become affected in the future. This article, based on technical discussions at the "Epidemiological and Sociological Determinants of Chagas Disease, Basic Information to Establish a Surveillance and Control Policy " meeting in Rio de Janeiro, is designed to open the debate on appropriate strategies for continuation of the successful initiatives against Chagas disease.

Chagas disease is a zoonosis caused by the protozoa Trypanosoma cruzi. It is transmitted to humans by contact of triatomine bug faeces with a break in the skin (often caused by a bite from the triatomine bug), or with mucous membranes. Transmission by contaminated blood transfusion, accidental expos...ure to blood, mother-to-child (during pregnancy or childbirth) or consumption of contaminated food and water is also possible.
Chagas disease has two phases: an acute phase, which lasts approximately 4 to 6 weeks, and a chronic phase, which is lifelong if left untreated.
The disease is primarily found on the American continent. It is significantly underdiagnosed.

Chagas disease is a parasitic zoonosis caused by Trypanosoma cruzi, a protozoan whose transmission to humans is primarily vector-borne. It is estimated that 6–8 million people worldwide are inf...ected and that 65–100 million people are at risk of becoming infected. Its clinical spectrum is very broad. During the acute phase, non-specific manifestations develop that may go unnoticed. During the chronic phase, specific manifestations develop that are diagnosed late and increase the morbidity and mortality of those suffering from it.

This is a tool meant to share and train the healthcare workers with precise and updated information about Chagas disease, in order to increase the amount of diagnostics and treatments amongst the affected people.
This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline dev...elopment (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.
