Difficulties in using 1,3-{beta}-D-glucan as the screening test for the early diagnosis of invasive fungal infections in patients with haematological malignancies--high frequency of false-positive results and their analysis

Popis výsledku v původním jazyce

We have evaluated the contribution of 1,3-ß-D-glucan (BG) assay for screening of invasive fungal diseases (IFI) in patients with hematological malignancies. Serum samples from patients at risk of IFI were collected twice a week and retrospectively testedusing the BG assay. BG screening was performed on 1143 samples from 91 patients during 104 anticancer treatment cycles. Proven and probable cases of IFI occurred in 9 (8.7%) treatment cycles. Depending on the criterion of positivity used (1> 60 or 1> 80pg/ml and 2> 60 or 2> 80 pg/ml) the sensitivity was 89%, 89%, 67% and 44%. Although the test was marked as positive in 82%, 68%, 54% and 45% of all the treatment cycles, in the majority of cases, these positivities were probably false. The major limit of the BG test was extremely low PPV (10% to 12%). Thus, the BG detection has a limited usefulness as a screening method for invasive fungal infections in patients with hematological malignancies.
