The pathogenesis of Chagas' disease: when autoimmune and parasite-specific immune responses meet
Provedor de dados: 42
Autores: SOARES,MILENA B. P.; PONTES-DE-CARVALHO,LAIN; RIBEIRO-DOS-SANTOS,RICARDO.
Chagas' disease is a major health problem in Latin America, where it constitutes one of the leading causes of heart failure. About one fourth of Trypanosoma cruzi-infected individuals develop chronic chagasic cardiomyopathy (CChC), the most severe form of the disease. CChC is histologically characterized by the presence of multifocal inflammatory infiltrates in the heart, composed mainly by mononuclear cells, usually adhered to myocytes and leading to myocytolysis, and frequently by interstitial fibrosis. The pathogenesis of CChC is still unclear, despite intense investigations both in human beings and in animal models of the disease. Although tissue parasitism is rare in the chronic phase of infection, an immune response targeted to persistent parasites...

Case report about the interaction of chronic myocarditis and General Adaptation Syndrome ("stress") causing rupture of left ventricular wall on a young, female specie of Cygnus atratus (black swan), that came to die at the Country Zoo of Taboão da Serra, in São Paulo, during quarantine, after being taken on a long distance travel, under disfavorable temperature and ventilation conditions.

A case of myopericarditis associated to Campylobacter jejuni infection in the southern hemisphere
Provedor de dados: 55
Autores: Fica,Alberto; Seelmann,Daniela; Porte,Lorena; Eugenin,Daniela; Gallardo,Ricardo.
Myopericarditis is an infrequent complication of acute diarrheal illness due to Campylobacter jejuni, and it has been mainly reported in developed nations. The first case detected in Chile - an upper-middle income country -, that is coincidental with the increasing importance of acute gastroenteritis associated to this pathogen, is described. Recognition of this agent in stools requires special laboratory techniques not widely available, and it was suspected when a young patient presented with acute diarrhea, fever, and chest pain combined with electrocardiogram (EKG) abnormalities and elevated myocardial enzymes. C. jejuni myopericarditis can easily be suspected but its detection requires dedicated laboratory techniques.

Prevalence of hepatitis C and B virus infection in patients with idiopathic dilated cardiomyopathy in Brazil: a pilot study
Provedor de dados: 55
Autores: Reis,Francisco J.F.B.; Viana,Mateus; Oliveira,Manoela; Sousa,Tiago A.; Paraná,Raimundo.
The idiopathic dilated cardiomyopathy (IDMC) is a disease of the cardiac muscle characterized by systolic dilation and/or dysfunction of one or both ventricles, symptoms of congestive heart failure and risk of early death. Several studies in animal models and in humans have supported the hypothesis of the viral infection as initial event in the immunopathogenesis of the ventricular dilation. The objective of this study was to correlate the presence of hepatitis C virus chronic infection and idiopathic dilated cardiomyopathy, comparing samples of cases with IDCM with paired controls with Chagas-type specific dilated cardiomyopathy and ischemic-type specific dilated cardiomyopathy. Only 2.9% (1/34) of IDCM patients were HCV carriers, which strongly argue...

Emerging acute Chagas Disease in Amazonian Brazil: case reports with serious cardiac involvement
Provedor de dados: 55
Autores: Pinto,Ana Yecê das Neves; Valente,Sebastião Aldo da Silva; Valente,Vera da Costa.
Four cases of serious cardiac attacks by autochthonous Trypanosoma cruzi infection from the Brazilian Amazon are reported; three of them occurred in micro-epidemic episodes. The manifestations included sudden fever, myalgia, dyspnea and signs of heart failure. Diagnosis was confirmed by specific exams, especially QBC (Quantitative Buffy Coat) and natural xenodiagnosis. Despite treatment with benznidazol, three patients died with serious myocarditis, renal failure and cardiac tamponade. The authors call attention to the emergence of this disease and reveal a previously unknown pathogenicity of T. cruzi strains in this area, added to a non-usual transmission form.

Endothelin-1 receptors play a minor role in the protection against acute Trypanosoma cruzi infection in mice
Provedor de dados: 56
Autores: Roffê,E.; Souza,A.L.S.; Machado,P.P.; Barcelos,L.S.; Romanha,A.J.; Mariano,F.S.; Silva,J.S.; Machado,C.R.; Tanowitz,H.B.; Teixeira,M.M.
Chagas' disease, caused by the protozoan Trypanosoma cruzi, is a major cause of cardiovascular disability in countries where it is endemic. Damage to the heart microvasculature has been proposed to be an important factor in the pathogenesis of heart dysfunction. Endothelin-1 (ET-1) is a potent vasoconstrictor and exerts its effects via specific ET A and ET B receptors. A few studies have suggested a role for ET-1 and its receptors in the pathogenesis of Chagas' disease. We investigated the effects of treatment with bosentan, an ET A/ET B receptor antagonist, on the course of T. cruzi infection (Y strain) in C57Bl/6 mice. Treatment with bosentan (100 mg kg-1 day-1) was given per os starting day 0 after infection until sacrifice. Bosentan significantly...

Abstract Histophilus somni is a Gram-negative bacterium that is associated with a disease complex (termed histophilosis) that can produce several clinical syndromes predominantly in cattle, but also in sheep. Histophilosis is well described in North America, Canada, and in some European countries. In Brazil, histophilosis has been described in cattle with respiratory, reproductive, and systemic disease, with only one case described in sheep. This report describes the occurrence of Histophilus somni-associated disease in sheep from Southern Brazil. Eight sheep with different clinical manifestations from five farms were investigated by a combination of pathological and molecular diagnostic methods to identify additional cases of histophilosis in sheep from...
