In order to characterize the demographic and clinical profile of patients with digestive manifestations of Chagas' disease, the medical records were reviewed of patients (n = 377) currently attended at Hospital das Clinicas da Faculdade de Medicina de Ribeirão Preto with positive serologic reaction for Chagas' disease and admitted from January 2002 to March 2003. Median age was 67 years and 210...

To compare parasitism and inflammatory process in esophagus and colon from chronic chagasic patients, immunohistochemistry was carried out to research for T. cruzi and to evaluate the inflammatory infiltrate in the muscular and myenteric plexus in 39 esophagi (20 with and 19 without megaesophagus) and 50 colons (25 with and 25 without megacolon). The frequency of T. cruzi in megaesophagus was 2...

BACKGROUND It has always been very controversial to choose an ideal operation for patients with no advanced recurrent megaesophagus after previous treatment. The various existing techniques and the different degrees of disease are the major factors to this difficulty. AIM To evaluate the early and late results of the Serra-Doria esophagocardioplasty in patients who had recurrence of symptoms ...

The persistence of Trypanosoma cruzi in tissue and blood of 52 patients in the digestive form of chronic Chagas disease was studied. These patients had chagasic megaesophagus and underwent corrective surgery. Parasitologic (xenodiagnosis, hemoculture, or both), histopathologic (hematoxylin and eosin, and peroxidase-anti-peroxidase staining), and molecular (polymerase chain reaction [PCR] follow...

Trypanosoma cruzi, the etiological agent of Chagas disease, presents a high degree of intraspecific genetic variability, with possible implications for the clinical forms of the disease, like the development of cardiopathy, megaesophagus, and megacolon, alone or in combination. This tissue tropism involved in the pathogenesis of Chagas disease has still not been totally elucidated. Thus, the cu...

INTRODUCTION Chagasic megaesophagus (CM) is the most common digestive manifestation of Chagas disease in Brazil, and the State of Goiás is one of the most affected regions. In recent decades, the Hospital das Clínicas (HC)/Universidade Federal de Goiás (UFG) has been a reference center for the study and treatment of CM. The objective of this study was to characterize the current epidemiological...
