Rio de Janeiro, RJ, Brasil.Chagas disease (CD), caused by Trypanosoma cruzi, affects approximately 6 to 7 million people in Latin America, with cardiomyopathy being the clinical manifestation most commonly associated with patient death during the acute phase. The etiological treatment of CD is restricted to benznidazole (Bz) and nifurtimox (Nif), which involve long periods of administration, frequent side effects, and low efficacy in the chronic phase. Thus, combined therapies emerge as an important tool in the treatment of CD, allowing the reduction of Bz dose and treatment duration. In this sense, amiodarone (AMD), the most efficient antiarrhythmic drug currently available and prescribed to CD patients, is a potential candidate for combined treatment due to its known trypanocidal activity. However, the efficacy of AMD during the acute phase of CD and its interaction with Bz or Nif are still unknown. In the present study, using a well-established murine model of the acute phase of CD, we observed that the Bz/AMD combination was more effective in reducing the peak parasitemia than both monotherapy treatments. Additionally, the Bz/ AMD combination reduced (i) interleukin-6 (IL-6) levels in cardiac tissue, (ii) P-wave duration, and (iii) frequency of arrhythmia in infected animals and (iv) restored gap junction integrity in cardiac tissue. Therefore, our study validates AMD as a promising candidate for combined therapy with Bz, reinforcing the strategy of combined therapy for CD. IMPORTANCE Chagas disease affects approximately 6 to 7 million people worldwide, with cardiomyopathy being the clinical manifestation that most commonly leads to patient death. The etiological treatment of Chagas disease is limited to drugs (benznidazole and nifurtimox) with relatively high toxicity and therapeutic failures. In this sense, amiodarone, the most effective currently available antiarrhythmic drug prescribed to patients with Chagas disease, is a potential candidate for combined treatment due to its known trypanocidal effect. In the present study, we show that combined treatment with benznidazole and amiodarone improves the trypanocidal effect and reduces cardiac damage in acutely T. cruzi-infected mice.info:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZBarbosa, Juliana Magalhães ChavesRezende, Yasmin PedraMelo, Tatiana Galvão deOliveira, Gabriel deCascabulho, Cynthia MachadoPereira, Evelyn Nunes Goulart da SilvaDaliry, AnissaSalem, Kelly SalomãoLICENSElicense.txtlicense.txttext/plain; charset=utf-82991https://arca.fiocruz.br/bitstreams/b6c854b4-9b8c-4f47-9c63-0d514c69fbb2/download5a560609d32a3863062d77ff32785d58MD51falseAnonymousREADORIGINALJulianaBarbosa_KellySSalem_etal_IOC_2022.pdfJulianaBarbosa_KellySSalem_etal_IOC_2022.pdfapplication/pdf4003437https://arca.fiocruz.br/bitstreams/3cce67df-af2d-490b-add4-50dc01ace113/downloadbc42c220c97b83ff3d1d5f274052b590MD52trueAnonymousREADTEXTJulianaBarbosa_KellySSalem_etal_IOC_2022.pdf.txtJulianaBarbosa_KellySSalem_etal_IOC_2022.pdf.txtExtracted texttext/plain60672https://arca.fiocruz.br/bitstreams/e2dd18d7-043c-4d26-a6e0-9031e34b1697/download04861f0f5feb295da0642234ed1f98e6MD513falseAnonymousREADTHUMBNAILJulianaBarbosa_KellySSalem_etal_IOC_2022.pdf.jpgJulianaBarbosa_KellySSalem_etal_IOC_2022.pdf.jpgGenerated Thumbnailimage/jpeg37903https://arca.fiocruz.br/bitstreams/a3582b12-e79b-4ffa-8f60-83389aa87176/downloadb398dc4e0058ee6a45679d6545e20342MD514falseAnonymousREADicict/515692025-12-10 15:42:01.289open.accessoai:arca.fiocruz.br:icict/51569https://arca.fiocruz.brRepositório InstitucionalPUBhttps://www.arca.fiocruz.br/oai/requestrepositorio.arca@fiocruz.bropendoar:21352025-12-10T18:42:01Repositório Institucional da FIOCRUZ (ARCA) -
