Journal ArticleDOI
A randomized, blinded, comparative trial of one pepsin-digested and two whole IgG antivenoms for Bothrops snake bites in Uraba, Colombia. The Regional Group on Antivenom Therapy Research (REGATHER).
R. Otero-Patino,J. L. C. Cardoso,Hisako Gondo Higashi,V Núñez,Álvaro Paúl Díaz,María Fabiola Toro,M. E. Garcia,A. Sierra,L. F. Garcia,A. M. Moreno,M. C. Medina,N. Castaneda,J. E. Silva-Diaz,M. Murcia,Silvia Cárdenas,W. D. Dias Da Silva +15 more
TL;DR: It is concluded that the efficacy of the three antivenoms was similar in neutralizing human Bothrops envenomings and that the production of whole IgG antivenom by caprylic acid fractionation is a good alternative for reducing the incidence of EARs.
Journal ArticleDOI
Preclinical assessment of the neutralizing capacity of antivenoms produced in six Latin American countries against medically-relevant Bothrops snake venoms.
Álvaro Segura,M.C. Castillo,Vitelbina Núñez,Armando Yarlequé,Luis Roberto de Camargo Gonçalves,Mauren Villalta,Cesar Bonilla,María Herrera,Marianela Vargas,Maritza Fernandez,Marcio Y. Yano,H.P. Araújo,M.A.A. Boller,P. León,B. Tintaya,Ida S. Sano-Martins,Aarón Gómez,G.P. Fernández,Patricia Geoghegan,Hisako Gondo Higashi,Guillermo León,José María Gutiérrez +21 more
TL;DR: The capacity of these antivenoms to neutralize, in preclinical tests, homologous and heterologous Bothrops venoms in Central and South America is revealed, and quantitative differences in the values of Median Effective Doses (ED50s) between the various antivenOMs are highlighted.
Journal ArticleDOI
Production of the first effective hyperimmune equine serum antivenom against Africanized bees.
Keity Souza Santos,Marco Antonio Stephano,José Roberto Marcelino,Virginia Maria Resende Ferreira,Thalita Rocha,Celso Pereira Caricati,Hisako Gondo Higashi,Ana Maria Moro,Jorge Kalil,Osmar Malaspina,Fabio Fernandes Morato Castro,Mario Sergio Palma +11 more
TL;DR: A F(ab)´2-based antivenom raised in horse as a potential new treatment for victims of multiple bee stings that contains high specific IgG titers and is effective in neutralizing toxic effects, such as hemolysis, cytotoxicity and myotoxicity.
Journal ArticleDOI
Vero-cell rabies vaccine produced using serum-free medium.
N. M. Frazatti-Gallina,Regina Maria Mourão-Fuches,Rosana L. Paoli,Maria L.N. Silva,Cosue Miyaki,Elizabeth Juliana Ghiuro Valentini,Isaias Raw,Hisako Gondo Higashi +7 more
TL;DR: The effective immunogenicity induced in mice by this vaccine, the degree of purity of the product, the high antigen yield and the reduction of the cost of the products due to the virus production and purification processes, makes this technology very important for countries where rabies presents a great public health problem.
Journal ArticleDOI
Neutralization of crotaline snake venoms from Central and South America by antivenoms produced in Brazil and Costa Rica.
Guisella Bogarín,Josefina Farina Morais,I.K. Yamaguchi,Marco Antonio Stephano,José Roberto Marcelino,Amélia Keiko Nishikawa,Rosalvo Guidolin,Gustavo Rojas,Hisako Gondo Higashi,José María Gutiérrez +9 more
TL;DR: Evidence of an extensive cross reactivity between these antivenoms and Central and South American crotaline snake venoms is provided.
