The BENEFIT Trial: Evaluation of the Use of an Antiparasital Drug (Benznidazole) in the Treatment of Chronic Chagas' Disease
The purpose of this study is to determine if 60 days of treatment with an antiparasitic drug (benznidazole) could prevent the progression of cardiac disease in patients with Chagas disease.
The BENEFIT study is being conducted by the Population Health Research Institute (in Hamilton, Canada) and the Institute Dante Pazzanese de Cardiologia (Sao Paulo, Brazil) together with an independent Steering Committee.
A randomized double-blind controlled clinical trial investigating the role of benznidazole in patients with chronic Chagas' heart disease.
Chagas disease has 3 phases: acute, undetermined and chronic phases. There are no clinical trials up to date that have investigated the use of antiparasitic drugs in patients that are in the chronic phase.
This study will evaluate the efficacy and safety of benznidazole (an antiparasitic drug) in patients with chronic Chagas' heart disease. It will evaluate if 60 days of drug treatment will reduce mortality and morbidity in patients with chronic Chagas' heart disease on several outcomes. It will be developed in 75 study centres in Argentina, Brazil, Colombia, Venezuela, Peru and Bolivia - countries with high incidence of Chagas Disease.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Medical and Biotech [MESH] Definitions
A disease of the CARDIAC MUSCLE developed subsequent to the initial protozoan infection by TRYPANOSOMA CRUZI. After infection, less than 10% develop acute illness such as MYOCARDITIS (mostly in children). The disease then enters a latent phase without clinical symptoms until about 20 years later. Myocardial symptoms of advanced CHAGAS DISEASE include conduction defects (HEART BLOCK) and CARDIOMEGALY.
Infection with the protozoan parasite TRYPANOSOMA CRUZI, a form of TRYPANOSOMIASIS endemic in Central and South America. It is named after the Brazilian physician Carlos Chagas, who discovered the parasite. Infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of PARASYMPATHETIC GANGLIA; CHAGAS CARDIOMYOPATHY; and dysfunction of the ESOPHAGUS or COLON.
A nitrovinyl furan used as a schistosomicidal agent and proposed for trypanosomiasis, especially Chagas disease.
The agent of South American trypanosomiasis or CHAGAS DISEASE. Its vertebrate hosts are man and various domestic and wild animals. Insects of several species are vectors.
A subfamily of assassin bugs (REDUVIIDAE) that are obligate blood-suckers of vertebrates. Included are the genera TRIATOMA; RHODNIUS; and PANSTRONGYLUS, which are vectors of TRYPANOSOMA CRUZI, the agent of CHAGAS DISEASE in humans.
The investigators propose the evaluation of posaconazole and benznidazole in humans for the treatment of Chagas disease chronical infection. Exploratory trial of posaconazole antiparasitic...
To examine the genetics of human susceptibility to Chagas' disease, a leading cause of heart disease throughout Latin America.
Chagas disease is endemic to the Americas, infecting between 16-18 million individuals. In immigrant populations in the United States from endemic areas, it is estimated up to 4.9% may be...
A detailed review was made of data pertinent to the occurrence of chronic Chagas disease in the United States.
The treatment human African trypanosomiasis (HAT) in the meningoencephalitic phase relies on two molecules officially registered: melarsoprol, the most commonly used, has a poor safety pro...
Drugs available for Chagas disease treatment are toxic and ineffective. We studied the in vivo activity of a new drug, lychnopholide (LYC). LYC was loaded in nanocapsules (NC) and its effects were com...

The Trypanosoma cruzi satellite DNA (satDNA) OligoC-TesT is a standardised PCR format for diagnosis of Chagas disease. The sensitivity of the test is lower for discrete typing unit (DTU) TcI than for...
Kissing bugs, vectors of Trypanosoma cruzi, the parasite that causes Chagas disease are common in the desert Southwest. Following a dispersal flight in summer, adult kissing bugs occasionally gain acc...
The current Chagas disease treatment is based on two drugs, nifurtimox and benznidazole, which is considered unsatisfactory, not only because of the narrow therapeutic range but also because of the as...
