Item Active surveillance of candidemia in children from Latin America: a key requirement for improving disease outcome.(Lippincott Williams & Wilkins, 2014) Santolaya, María; Alvarado-Matute, Tito; Queiroz-Telles, Flavio; Colombo, Arnaldo; Zurita, Jeanette; Tiraboschi, Iris; Cortes, Jorge; Thompson, Luis; Guzman, Manuel; Sifuentes, José; Echevarria, Juan; Nucci, Marcio; Latin American Invasive Mycosis NetworkBACKGROUND: Active surveillance is necessary for improving the management and outcomes of patients with candidemia. The aim of this study was to describe the epidemiologic and clinical features of candidemia in pediatric patients in Latin America. METHOD: Prospective, multicenter, surveillance study of candidemia in a pediatric population from 23 hospitals in 8 Latin America countries between November 2008 and October 2010. RESULTS: Three hundred and two cases of candidemia were reported with a median incidence of 0.81/1000 admissions. Eighty nine (29%) were neonates. The main risk factors were prematurity, intensive care unit (ICU) admission, parenteral nutrition, respiratory disease and mechanical ventilation in neonates and malignancy, neutropenia, neurological disease and previous use of corticosteroids in children. The main species isolated in neonates and children were Candida albicans (43.8% and 35.7%), Candida parapsilosis (27.0% and 26.3%) and Candida tropicalis (14.6% and 14.6%), respectively. The most frequent antifungal therapy used in neonates and children was deoxycholate-amphotericin-B (43.8% and 29.1%) and fluconazole (28.1% and 53.1%). Seventeen neonates (19.1%) and 20 children (9.4%) did not receive antifungal therapy. The 30-day survival rate was 60% in neonates and 72% in children (P = 0.02). Survival was significantly higher in treated than in nontreated neonates (72% vs. 24%; P < 0.001). A multivariate analysis showed that independent predictors for 30-day mortality in children were renal disease (odds ratio: 4.38, 95% confidence interval: 1.92-10.1, P < 0.001) and receipt of corticosteroids (odds ratio: 2.08, 95% confidence interval: 1.04-4.17, P = 0.04). CONCLUSIONS: To our knowledge, this is the first prospective, multicenter surveillance study of candidemia in children in Latin America. This epidemiologic information may provide us with methods to improve preventive, diagnostic and therapeutic strategies in our continent.Item Recommendations for the diagnosis of candidemia in Latin America(Asociacion Española de Micologia, 2013) Colombo, Arnaldo; Cortes, Jorge; Zurita, Jeannete; Guzman-Blanco, Manuel; Alvarado-Matute, Tito; de Queiroz Telles, Flavio; Santolaya, María; Tiraboschi, Iris; Echevarría, Juan; Sifuentes, Jose; Thompson-Moya, Luis; Nucci, MarcioCandidemia is one of the most frequent opportunistic mycoses worldwide. Limited epidemiological studies in Latin America indicate that incidence rates are higher in this region than in the Northern Hemisphere. Diagnosis is often made late in the infection, affecting the initiation of antifungal therapy. A more scientific approach, based on specific parameters, for diagnosis and management of candidemia in Latin America is warranted. 'Recommendations for the diagnosis and management of candidemia' are a series of manuscripts that have been developed by members of the Latin America Invasive Mycosis Network. They aim to provide a set of best-evidence recommendations for the diagnosis and management of candidemia. This publication, 'Recommendations for the diagnosis of candidemia in Latin America', was written to provide guidance to healthcare professionals on the diagnosis of candidemia, as well as on the usefulness and application of susceptibility testing in patients who have a confirmed diagnosis of candidemia. Computerized searches of existing literature were performed by PubMed. The data were extensively reviewed and analyzed by members of the group. The group also met on two occasions to pose questions, discuss conflicting views, and deliberate on a series of management recommendations. 'Recommendations for the diagnosis of candidemia in Latin America' includes diagnostic methods used to detect candidemia, Candida species identification, and susceptibility testing. The availability of methods, their costs and treatment settings are considered. This manuscript is the first of this series that deals with diagnosis and treatment of invasive candidiasis. Other publications in this series include: 'Recommendations for the management of candidemia in adults in Latin America', 'Recommendations for the management of candidemia in children in Latin America', and 'Recommendations for the management of candidemia in neonates in Latin America'.
