La Tripanosomiasis americana es aún un problema de salud pública en la región Arequipa, por tal razón se realizó un estudio en escolares de la IE San José de Tiabaya; con el objetivo de determinar la seroprevalencia, las características electrocardiográficas (EKG) y ecocardiográficas (ECCG), más frecuentes de los casos seropositivos, así como describir las características epidemiológicas y los conocimientos sobre Triatoma infestans (“Chirimacha”). Para ello se estudiaron 381 escolares, con consentimiento informado, mediante los métodos de ELISA e IFI y se realizaron EKG y ECCG en el HRGHD, y se aplicó una ficha epidemiológica. La seroprevalencia a Trypanosoma cruzi en los escolares fue de 7.09% (27/381), la característica más frecuente de los casos seropositivos a T. cruzi, al EKG y al ECCG es normal con 88.9% y solo el 11.1% presento alteraciones cardiacas, un caso...

Objective: To determine the value of indirect immunofluorescence (IFI) in the diagnosis of leishmaniasis and Chagas disease. Material and method: Indirect immunofluorescence (IFI) was employed for diagnosing leishmaniasis and Chagas disease using Trypanosoma cruzi epimastigota as substrate antigens. A nuclear fluorescence pattern was found in sera from patients with leishmaniasis, and a peripheral pattern was found in those with Chagas disease. Afterwards, we estimated the diagnostic value of IFI for both diseases in a blinded fashion. Results: For diagnosing leishmaniasis, IFI sensitivity was 84.2%, specificity, 100%, positive predictive value, 100%, negative predictive value 82.9%, and accuracy was 91.0%. Conclusions: The immunofluorescence technique using Trypanosoma cruzi epimastigota, considering the proposed color patterns, is useful for diagnosing cutaneous lei...
