La Unidad Académica Santa Cruz comprometida con el desarrollo científico al servicio de la sociedad boliviana cuenta con dos unidades de investigación en el área de salud: Instituto de investigación en Medicina conformado el año 2012, con más de 6 años de experiencia en proyectos de investigación en el área de enfermedades infecciosas y otros, y la carrea de Odontología, que cuanta con una gran cantidad de producción científica en torno a rehabilitación oral y otras temáticas abordadas desde la clínica odontológica. La participación en investigación de estudiantes de pre grado es fundamental, la misma se ve reflejada y conglomerada en dos sociedades científicas: Sociedad Científica de Estudiantes de Medicina y la Sociedad Científica de estudiantes de Odontología.

    Biomarkers in Trypanosomacruzi -Infected and Uninfected Individuals with Varying Severity of Cardiomyopathy in Santa Cruz, Bolivia
    (PLOS Neglected Tropical Diseases, 2014) Okamoto, Emi E.; Sherbuk, Jacqueline E.; Clark, Eva H.; Marks, Morgan A.; Gandarilla, Omar; Galdos-Cardenas, Gerson; Vasquez-Villar, Angel; Choi, Jeong
    Background: Twenty to thirty percent of persons with Trypanosoma cruzi infection eventually develop cardiomyopathy. If an early indicator were to be identified and validated in longitudinal studies, this could enable treatment to be prioritized for those at highest risk. We evaluated cardiac and extracellular matrix remodeling markers across cardiac stages in T. cruzi infected (Tc+) and uninfected (Tc2) individuals. Methods: Participants were recruited in a public hospital in Santa Cruz, Bolivia and assigned cardiac severity stages by electrocardiogram and echocardiogram. BNP, NTproBNP, CKMB, troponin I, MMP-2, MMP-9, TIMP-1, TIMP-2, TGFb1, and TGFb2 were measured in specimens from 265 individuals using multiplex bead systems. Biomarker levels were compared between Tc+ and Tc2 groups, and across cardiac stages. Receivers operating characteristic (ROC) curves were created; for markers with area under curve.0.60, logistic regression was performed. Results: Analyses stratified by cardiac stage showed no significant differences in biomarker levels by Tc infection status. Among Tc+ individuals, those with cardiac insufficiency had higher levels of BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 than those with normal ejection fraction and left ventricular diameter. No individual marker distinguished between the two earliest Tc+ stages, but in ROC-based analyses, MMP-2/MMP-9 ratio was significantly higher in those with than those without ECG abnormalities. Conclusions: BNP, NTproBNP, troponin I, MMP-2, TIMP-1, and TIMP-2 levels rose with increasing severity stage but did not distinguish between Chagas cardiomyopathy and other cardiomyopathies. Among Tc+ individuals without cardiac insufficiency, only the MMP-2/MMP-9 ratio differed between those with and without ECG changes.
