[Diagnostic methods in candidemia: a systematic review of literature with meta-analysis].

Abstract

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.
