Randomized Trial of Benznidazole for Chronic Chagas' Cardiomyopathy.

Background: The role of trypanocidal therapy in patients with established Chagas' cardiomyopathy is unproven.

Methods: We conducted a prospective, multicenter, randomized study involving 2854 patients with Chagas' cardiomyopathy who received benznidazole or placebo for up to 80 days and were followed for a mean of 5.4 years.

Developments in the treatment of leishmaniasis and trypanosomiasis.

The leishmaniases and trypanosomiases are diseases caused by related parasites belonging to the kinetoplastidae family. They share common biological traits, which are comparatively better known than for other parasites, and which would favour the identification of common targets. Yet, very few new drugs are on the horizon and treatment relies on old, often toxic and ineffective drugs.

Human infection by Fasciola hepatica in Venezuela: report of a geriatric case.

A new case of human infection due to Fasciola hepatica is reported in the Venezuelan parasitological literature. The patient is an 81-year-old female asymptomatic, with an eosinophilia of 21% and critrosedimentation rate of 26 mm/h and was found during a routine check up. These values were normal at the time of treatment (4 months later), as were several tests of hepatic function, blood chemistry and peripheral blood haematological values.

Strategic emphases for tropical diseases research: a TDR perspective.

Setting priorities for health research is a difficult task, especially for the neglected diseases of the poor. A new approach to priority setting for tropical diseases research has been adopted by the UNDP/World Bank/WHO Special Programme for Research and Training in Tropical Diseases (known as the TDR). Priorities are defined on the basis of a comprehensive analysis of research needs and research opportunities for each of the ten major tropical diseases in the TDR portfolio.
