Abstract
INTRODUÇÃO: Foi realizado um estudo soroepidemiológico e clínico em 152 indivíduos residentes no município de Barcelos, Estado do Amazonas. Avaliou-se a soroprevalência da infecção chagásica e a morbidade da doença de Chagas. MÉTODOS: Os testes sorológicos foram a imunofluorescência indireta, ELISA convencional e recombinante e o Tesa-blot. Foram considerados soropositivos 38 pacientes, duvidosos 31 e soronegativos negativos 83. Os 38 casos soropositivos foram pareados com 38 controles soronegativos da mesma idade, sexo e submetidos à avaliação epidemiológica, clínica, eletro e ecocardiográfica, sendo que, 29 pares fizeram exame radiológico do esôfago. RESULTADOS: A soropositividade foi 19,9 vezes mais frequente nos trabalhadores do extrativismo em geral e 10,4 vezes mais frequente no extrativismo da piaçaba. Aplicou-se o teste de reconhecimento com o vetor local do gênero Rhodnius e 86,7% dos pacientes soropositivos o reconheceram, enquanto somente 34,2% dos soronegativos o fizeram. O ECG mostrou-se alterado em 36,8% nos soropositivos e em 21,5% nos soronegativos, enquanto o ecocardiograma mostrou alterações em 31,6% nos soropositivos e 18,4% nos soronegativos. Precordialgia e palpitações foram mais frequentes nos soropositivos. O estudo clínico do aparelho digestivo e radiológico do esôfago não mostrou alterações significativas. CONCLUSÕES. A doença de Chagas na região estudada pode ser considerada uma doença ocupacional.
INTRODUCTION: A seroepidemiological and clinical study was conducted on 152 autochthonous individuals living in the district of Barcelos, State of Amazonas, to evaluate the seroprevalence of Chagas infection and morbidity of Chagas disease. METHODS: The serological tests used were indirect immunofluorescence, conventional and recombinant ELISA and immunoblot (Tesa-blot). Thirty-eight patients were considered seropositive; 31 were considered serodoubtful; and 83 were considered seronegative. The 38 seropositive cases were paired with 38 seronegative controls of the same age and sex, and underwent epidemiological and clinical evaluations, electrocardiograms and echocardiograms. Twenty-nine pairs underwent radiological examinations of the esophagus. RESULTS: Seropositivity was 19.9 times more frequent among workers gathering plant materials from the forests and 10.4 times more frequent among piassaba gatherers. Eighty six point seven percent of the seropositive individuals recognized the genus Rhodnius as the local vector, while only 34.2% of the seronegative individuals recognized this. The EKG was abnormal in 36.8% of the seropositive individuals and in 21.5% of the seronegative individuals, while the echocardiogram showed abnormalities in 31.6% of the seropositive and 18.4% of the seronegative individuals. Precordialgia and palpitation were more frequent among the seropositive individuals. Clinical evaluation on the digestive system and X-ray on the esophagus did not show significant abnormalities. CONCLUSIONS: Chagas disease in the study region can be considered to be an occupational disease.
