Epidemiology of Candidemia in Latin America: A Laboratory-Based Survey

Abstract

Background: the epidemiology of candidemia varies depending on the geographic region. Little is known about the epidemiology of candidemia in Latin America.Methods: We conducted a 24-month laboratory-based survey of candidemia in 20 centers of seven Latin American countries. Incidence rates were calculated and the epidemiology of candidemia was characterized.Results: Among 672 episodes of candidemia, 297 (44.2%) occurred in children (23.7% younger than 1 year), 36.2% in adults between 19 and 60 years old and 19.6% in elderly patients. the overall incidence was 1.18 cases per 1,000 admissions, and varied across countries, with the highest incidence in Colombia and the lowest in Chile. Candida albicans (37.6%), C. parapsilosis (26.5%) and C. tropicalis (17.6%) were the leading agents, with great variability in species distribution in the different countries. Most isolates were highly susceptible to fluconazole, voriconazole, amphotericin B and anidulafungin. Fluconazole was the most frequent agent used as primary treatment (65.8%), and the overall 30-day survival was 59.3%.Conclusions: This first large epidemiologic study of candidemia in Latin America showed a high incidence of candidemia, high percentage of children, typical species distribution, with C. albicans, C. parapsilosis and C. tropicalis accounting for the majority of episodes, and low resistance rates.independent medical grant from Pfizer Inc.Univ Fed Rio de Janeiro, Univ Hosp, Rio de Janeiro, BrazilUniv Fed Parana, Hosp Clin, BR-80060000 Curitiba, Parana, BrazilHosp Escuela Tegucigalpa, Tegucigalpa, HondurasHosp Clin Jose San Martin, Buenos Aires, DF, ArgentinaUniv Nacl Colombia, Dept Internal Med, Bogota, ColombiaPontificia Univ Catolica Ecuador, Fac Med, Hosp Vozandes, Quito, EcuadorHosp Vargas de Caracas, Caracas, VenezuelaCtr Med Caracas, Caracas, VenezuelaUniv Chile, Fac Med, Dept Pediat, Hosp Luis Calvo Mackenna, Santiago 7, ChileUniv Desarrollo, Clin Alemana, Dept Med, Infect Dis Unit, Santiago, ChileInst Nacl Ciencias Med & Nutr Salvador Zubiran, Mexico City, DF, MexicoUniv Peruana Cayetano Heredia, Dept Med, Lima, PeruUniversidade Federal de São Paulo, Escola Paulista Med, Div Infect Dis, São Paulo, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, Div Infect Dis, São Paulo, BrazilWeb of Scienc
