  • Congenital Chagas disease in Santa Cruz Department, Bolivia, is dominated by Trypanosoma cruzi lineage V 
    Sanchez, Leny; Messenger, Louisa A.; Bhattacharyya, Tapan; Gilman, Robert Hugh; Mayta, Holger; Colanzi, Rony; Bozo, Ricardo; Verastegui Pimentel, Manuela Renee; Miles, Michael A.; Bern, Caryn (Oxford University Press, 2021)
    BACKGROUND: This study identified Trypanosoma cruzi discrete typing units (DTUs) in maternal and infant specimens collected from two hospitals in Bolivia, using conventional genotyping and DTU-specific serotyping. METHODS: ...
  • Field evaluation of the InBios Chagas detect plus rapid test in serum and whole-blood specimens in Bolivia 
    Shah, Vishal; Ferrufino, Lisbeth; Gilman, Robert Hugh; Ramirez, Margot; Saenza, Eliana; Malaga, Edith; Sanchez, Gerardo; Okamoto, Emi E.; Sherbuck, Jacqueline E.; Clark, Eva H.; Galdos-Cardenas, Gerson; Bozo, Ricardo; Flores-Franco, Jorge Luis; Colanzi, Rony; Verastegui Pimentel, Manuela Renee; Bern, Caryn (American Society for Microbiology, 2014)
    Trypanosoma cruzi causes Chagas disease, which affects an estimated 7 million to 8 million people. Chagas disease is endemic throughout Latin America, with the highest prevalence in Bolivia. Conventional diagnosis requires ...
  • Improved DNA extraction technique from clot for the diagnosis of Chagas disease 
    Mayta, Holger; Romero, Yomara K.; Pando, Alejandra; Verastegui Pimentel, Manuela Renee; Tinajeros, Freddy; Bozo, Ricardo; Henderson-Frost, Josephine; Colanzi, Rony; Flores, Jorge; Lerner, Richard; Bern, Caryn; Gilman, Robert Hugh (Public Library of Science, 2019)
    BACKGROUND: The detection of Trypanosoma cruzi genetic material in clinical samples is considered an important diagnostic tool for Chagas disease. We have previously demonstrated that PCR using clot samples yields greater ...
  • Pupillary Light Reflexes are Associated with Autonomic Dysfunction in Bolivian Diabetics But Not Chagas Disease Patients 
    Halperin, Anthony; Pajuelo Travezaño, Monica Jhenny; Tornheim, Jeffrey A.; Vu, Nancy; Carnero, Andres M.; Galdos-Cardenas, Gerson; Ferrufino, Lisbeth; Camacho, Marilyn; Justiniano, Juan; Colanzi, Rony; Bowman, Natalie M.; Morris, Tiffany; MacDougall, Hamish; Bern, Caryn; Moore, Steven T.; Gilman, Robert Hugh (American Society of Tropical Medicine and Hygiene, 2016)
    Autonomic dysfunction is common in Chagas disease and diabetes. Patients with either condition complicated by cardiac autonomic dysfunction face increased mortality, but no clinical predictors of autonomic dysfunction ...
  • Sustained Domestic Vector Exposure Is Associated With Increased Chagas Cardiomyopathy Risk but Decreased Parasitemia and Congenital Transmission Risk Among Young Women in Bolivia 
    Kaplinski, Michelle; Jois, Malasa; Galdos-Cardenas, Gerson; Rendell, Victoria R.; Shah, Vishal; Do, Rose Q.; Marcus, Rachel; Pena, Melissa S. Burroughs; Abastoflor, Maria del Carmen; LaFuente, Carlos; Bozo, Ricardo; Valencia, Edward; Verastegui Pimentel, Manuela Renee; Colanzi, Rony; Gilman, Robert Hugh; Bern, Caryn (Oxford University Press, 2015)
    BACKGROUND: We studied women and their infants to evaluate risk factors for congenital transmission and cardiomyopathy in Trypanosoma cruzi-infected women. METHODS: Women provided data and blood for serology and quantitative ...
  • Toward Improving Early Diagnosis of Congenital Chagas Disease in an Endemic Setting 
    Messenger, Louisa A.; Gilman, Robert Hugh; Verastegui Pimentel, Manuela Renee; Galdos-Cardenas, Gerson; Sanchez, Gerardo; Valencia, Edward; Sanchez, Leny; Malaga, Edith; Rendell, Victoria R.; Jois, Malasa; Shah, Vishal; Santos, Nicole; Abastoflor, Maria Del Carmen; LaFuente, Carlos; Colanzi, Rony; Bozo, Ricardo; Bern, Caryn (Oxford University Press, 2017)
    Background: Congenital Trypanosoma cruzi transmission is now estimated to account for 22% of new infections, representing a significant public health problem across Latin America and internationally. Treatment during infancy ...
  • Trypanosoma cruzi-infected pregnant women without vector exposure have higher parasitemia levels: implications for congenital transmission risk 
    Rendell, Victoria R.; Gilman, Robert Hugh; Valencia, Edward; Galdos-Cardenas, Gerson; Verastegui Pimentel, Manuela Renee; Sanchez, Leny; Acosta, Janet; Sanchez, Gerardo; Ferrufino, Lisbeth; LaFuente, Carlos; Abastoflor, Maria del Carmen; Colanzi, Rony; Bern, Caryn (Public Library of Science, 2015)
    BACKGROUND: Congenital transmission is a major source of new Trypanosoma cruzi infections, and as vector and blood bank control continue to improve, the proportion due to congenital infection will grow. A major unanswered ...
