Aspectos clínicos, sociais e trabalhistas da doença de Chagas em área endêmica sob controle do Estado de Minas Gerais, Brasil

Abstract

Among 301 construction workers examined in Bambuí, Brasil, 11.6% presented positive serology for American trypanosomiasis, with a prevalence of 5.0% in the age group 17-29 years, 13.8% in the 30-39 and 39.4% in the 40-57. Electrocardiographic disturbances were detected in 31.3% of the seropositive and in 7.1% of the seronegative individuals, with a significant difference in the age group 40-57 years. Cardiac enlargement and esophagopathy were detected respectively in 8.6% and 8.6% of the positive and 1.5% and 0.8% of the negative group. Chagasic and non-Chagasic individuals came from the same region and social status, but the seropositive group was more associated with low scholarship and immediate antecedent of rural activities. The effectiveness of the programme of vector control installed in the Region in the years 1970 is once more confirmed by its positive impact on the prevalence and morbidity of human Chagas disease. Congenital and transfusional Chagas disease seem to play a very small epidemiologic role in the Region at the present time.

“…In all functional assessments of prognosis and working capacity of an individual with Chagas disease, the great clinical variability of these cases should be taken into account, even when in the same stage of any classification of cardiac impairment. Often, but not always, advanced disorders of stimulus conduction are associated with the severity of myocardial damage, leading to the need for a complementary evaluation of the degree of myocardial dysfunction, especially in cases where the work requires intense physical activity and involves personal or social risk (e.g., aviation pilots) (270) .…”

II Consenso Brasileiro em Doença de Chagas, 2015

“…Frequentemente, mas nem sempre, transtornos avançados da condução do estímulo associam-se à gravidade do comprometimento miocárdico, levando à necessidade de avaliação complementar do grau de disfunção miocárdica, especialmente nos casos em que o trabalhador exerce atividade física intensa e de risco pessoal ou social (como, por exemplo, pilotos de aviação). 270…”
