In vitro and in vivo drug combination for the treatment of Trypanosoma cruzi infection: A multivariate approach.

Combination therapies based on the available drugs have been proposed as promising therapeutic alternatives for many diseases. Clomipramine (CLO) has been found to modify the evolution of the experimental infection. The objective of this study was to evaluate the combined effect of benznidazole (BZ) and clomipramine (CLO) against different life-stages of Trypanosoma cruzi in vitro and their efficacy in a murine model.

Quantitative PCR and unconventional serological methods to evaluate clomipramine treatment effectiveness in experimental Trypanosoma cruzi infection.

Clomipramine (CLO), a tricyclic antidepressant drug, has been used for the treatment of mice infected with Trypanosoma cruzi. In this work we evaluated the effectiveness of CLO treatment upon T. cruzi-infected mice in the chronic phase of the experimental infection using Quantitative polymerase chain reaction (qPCR) and recombinant ELISA.

Chronic indeterminate phase of Chagas' disease: mitochondrial involvement in infection with two strains.

Chagasic cardiopathy has become one of the most frequent causes of heart failure and sudden death, as well as one of the most common causes of cardio-embolic stroke in Latin America. The myocyte response to oxidative stress involves the progression of cellular changes, primarily targeting the mitochondria and modifying therefore the energy supply. In this paper we analysed the effect of the infection of mice with 2 different strains of Trypanosoma cruzi (Tulahuen and SGO Z12) in the chronic indeterminate stage (75 days post-infection), upon the structure and function of cardiac mitochondria.
