RESUMO
UNLABELLED: Candidemia is a disease with high morbidity and mortality especially in critical care patients. Early diagnosis enables early treatment. OBJECTIVES: To conduct a systematic review of the literature in order to establish the best laboratory tests for the diagnosis of candidemia in critical patients. MATERIALS AND METHODS: We conducted a systematic review of available literature in PubMed. Serological studies were subjected to meta-analysis in metadisk-Beta 1.1.1. RESULTS: 4 studies of 1286 reviewed were included. Three were about serological tests and one about molecular testing (RT-PCR). The sensitivity and specificity for RT-PCR, antibody testing and antigen and antibody tests were 87% and 100%, 47.5% and 82.6%, 96% and 81%, respectively. Diagnostic Odds Ratio of antigenemia was 1.51 (95% CI = 0,032-70,964, p = 0.001). CONCLUSIONS: RT-PCR has better diagnostic performance, measuring antigenemia plus antibodies improves sensitivity, specificity, LR + and LR-- . There is insufficient evidence to support this.

La candidemia es una patología con alta morbilidad y mortalidad, especialmente en los pacientes sometidos a servicios de cuidado crítico. El diagnóstico precoz permite realizar tratamiento temprano. Objetivos: Realizar una revisión sistemática de la literatura para establecer cuáles son las pruebas de laboratorio con mejor rendimiento diagnóstico y operativo para el diagnóstico de candidemia en cuidado intensivo. Materiales y Métodos: Se realizó una revisión sistemática de la literatura disponible en PubMed, se sometieron a meta-análisis estudios de pruebas serológicas en MetaDisc-Beta 1.1.1. Resultados: Se incluyeron 4 estudios de 1.286 revisados, 3 de pruebas serológicas y 1 de RPC-RT. La sensibilidad y especificidad fue de 87 y 100 por ciento para RPC-RT, 47,5 y 82,6 por ciento para pruebas de anticuerpos, 96 y 81 por ciento para pruebas de antígeno y anticuerpo. La ORD de antigenemia 1,51(IC95 por ciento = 0,03270,964; p = 0,001). Conclusiones: RPC-RT tiene mejor rendimiento diagnóstico, la medición de antigenemia más anticuerpos mejora la sensibilidad, especificidad, LR+ y LR-. No hay suficiente evidencia que soporte esto.
