Chronic chagasic cardiomyopathy, which is caused by the protozoan Trypanosoma cruzi, is a major cause of heart failure in Latin America. It is a disease for which effective treatment in its advanced clinical forms is lacking. We have previously shown that bone marrow mononuclear cell (BMC) transplantation is effective in reducing inflammation and fibrosis in the mouse model of Chagas disease. The present study used magnetic resonance un-aging to assess changes in the cardiac morphology of infected mice after therapy with BMCs. Serial imaging of the BMC-treated mice revealed regression of the right ventricular dilatation typically observed in the chagasic mouse model.

    Background: Chagas disease, resulting from infection with the parasite Trypanosoma cruzi (T. cruzi), is a major cause of cardiomyopathy in Latin America. Drug therapy for acute and chronic disease is limited. Stem cell therapy with bone marrow mesenchymal cells (MSCs) has emerged as a novel...

    Chagasic megacolon has been reported in the southern cone countries of South America and is mainly associated with Trypanosoma cruzi II infection. Herein, we report the first case in Colombia of chagasic megacolon with cardiomyopathy associated with the T. cruzi I lineage. This finding suggests...

    Chagas disease, which is caused by the parasite Trypanosoma cruzi, is an important cause of cardiomyopathy in Latin America. It is estimated that 10%-30% of all infected individuals will acquire chronic chagasic cardiomyopathy (CCC). The etiology of CCC is multifactorial and involves parasite...

    We have previously shown that clomipramine and allopurinol used separately are effective in preventing chronic chagasic cardiomyopathy. The aim of the present study was to evaluate the effect of the association of clomipramine (Clo-5 mg/kg/day/90 days) and allopurinol (Allo-5, 10, or 15...

    The prevalence of chronic Chagas' heart disease as a cause of dilated cardiomyopathy is unknown in the State of Campeche, Mexico. A study was conducted to determine the prevalence of positive serology for Trypanosoma cruzi in patients with clinical diagnosis of dilated cardiomyopathy. Of a total...

    Summary: The pathogenesis of chronic chagasic cardiopathy is still under discussion; there is considerable evidence that inflammatory infiltrates and their mediators have a direct effect on cardiac cells. Here we studied the structure and function of cardiac mitochondria in chronic chagasic...

    Trypanosoma cruzi infection in humans and experimental animals causes Chagas disease which is often accompanied by myocarditis, cardiomyopathy, and vasculopathy. T. cruzi-derived thromboxane A (TXA) modulates vasculopathy and other pathophysiological features of Chagasic cardiomyopathy. Here, we...
