Item type: Item , Antibody drop in newborns congenitally infected by<i>Trypanosoma cruzi</i>treated with benznidazole(Wiley, 2009) Jean‐Philippe Chippaux; Alejandra N. Salas Clavijo; José Santalla; Jorge R. Postigo; Dominik T. Schneider; Laurent BrutusRecovery may be confirmed in most cases at 10 months. The CSP test was compared to Chagatest v3.0 ELISA and appeared to give a reliable response. The decrease rate of antibodies does not depend on treatment modes.Item type: Item , Appraisal of snakebite incidence and mortality in Bolivia(Elsevier BV, 2014) Jean‐Philippe Chippaux; Jorge R. PostigoItem type: Item , Epidemiological evaluation of Chagas disease in a rural area of southern Bolivia(Oxford University Press, 2008) Jean‐Philippe Chippaux; Jorge R. Postigo; José Santalla; Dominik T. Schneider; Laurent BrutusWe evaluated the prevalence of Chagas disease using a rapid screening test (Chagas Stat-Pak), confirmed by ELISA, in Caraparí, a village of 9000 inhabitants in southern Bolivian Chaco. The prevalence of Trypanosoma cruzi was estimated in a sample of 995 people. The prevalence adjusted on age was 51.2% and was proportionally related to age. We also observed a very significant cline from the south to the north of the locality, where the prevalence ranged from 40 to 80%. In children younger than 11 years, the prevalence was 21.5%, which confirmed the importance of residual vector transmission despite several years of vector control. Among women of procreation age, the prevalence was 63.9%, resulting in a high risk of congenital transmission. The control of the disease requires an increase in vector control and improvement of dwellings before considering children's treatment with trypanocide.Item type: Item , Evaluation of compliance to congenital Chagas disease treatment: results of a randomised trial in Bolivia(Oxford University Press, 2012) Jean‐Philippe Chippaux; A. N. Salas-Clavijo; Jorge R. Postigo; Dominique Schneider; José-Antonio Santalla; Laurent BrutusThe short treatment should be preferred as it allows reducing the dose of benznidazole as well as the cost of treatment.Item type: Item , Prevalence of Chagas disease in pregnant women and incidence of congenital transmission in Santa Cruz de la Sierra, Bolivia(Elsevier BV, 2012) Nadin A. Salas Clavijo; Jorge R. Postigo; Dominik T. Schneider; José Santalla; Laurent Brutus; Jean‐Philippe ChippauxItem type: Item , Sensitivity and specificity of Chagas Stat‐Pak<sup>®</sup> test in Bolivia(Wiley, 2009) Jean‐Philippe Chippaux; José Santalla; Jorge R. Postigo; Mario Romero; Nadin A. Salas Clavijo; Dominique Schneider; Laurent BrutusThe test is simple of use, reliable, relatively inexpensive (<2 US$ each test) and its performances are compatible with a field use for large-scale screenings.
