POMPILIO, Maurício Antonio et al. Epidemiological, clinical and parasitological aspects of Chagas' disease in Mato Grosso do Sul State. Rev. Soc. Bras. Med. Trop. [online]. 2005, vol.38, n.6, pp.473-478. ISSN 0037-8682.

With the objective of evaluating epidemiologic, clinical and parasitologic aspects of chronic Chagas' disease in patients from the University Hospital of the Federal University of Mato Grosso do Sul, a cross-sectional study was performed with groups of 120 chagasic and non-chagasic patients aged from 16 to 82 years. Epidemiologic aspects were evaluated by means of a questionnaire, cardiopathy by clinical examination, conventional electrocardiogram, radiology and Doppler echocardiograms (only in chagasic patients) and the presence of Trypanosoma cruzi in the blood stream by way of xenodiagnosis and polymerase chain reaction test. The results obtained indicated that the chagasic patients are predominantly alloctones with low-grade schooling, and were exposed to triatomines. The frequency of spontaneous abortion was higher in chagasic women. Chronic chagasic cardiopathy, estimated to occur in 20.2% of the patients, showed 7.5% cardiomegaly, 6.2% aneurysm of the left ventricle, and with a predominance of dyspnea, palpitations and arterial hypertension. Xenodiagnosis was positive for 26.1% of the chagasics and the PCR was positive for 53.7%, and was significantly higher in males and alloctones. An analysis of the results shows that Chagas' disease, in the group studied, presented clinical and parasitologic characteristics demonstrating significant regional differences.
