Abstract

CORTES, Jorge Alberto; CONCHA M, Alejandro; CEDIEL T, Luis Eduardo  and  CASTILLO, Juan Sebastián. Diagnostic methods in candidemia: a systematic review of literature with meta-analysis. Rev. chil. infectol. [online]. 2011, vol.28, n.5, pp.423-428. ISSN 0716-1018.  http://dx.doi.org/10.4067/S0716-10182011000600006.

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.

Keywords : Fungemia; candidemia; molecular diagnostic techniques; serology; systematic reviews.
