Galactomannan, Beta-D-Glucan and PCR-Based Assays for the Diagnosis of Invasive Fungal Disease in Pediatric Cancer and Hematopoietic Stem Cell Transplantation: A Systematic Review and Meta-Analysis.
Year of Publication
<p>We systematically reviewed and analyzed the available data for galactomannan (GM), beta-D-glucan (BG), and polymerase-chain reaction (PCR)-based assays to detect invasive fungal disease (IFD) in pediatric cancer or hematopoietic stem cell transplantation (HSCT) patients when used as screening tools during immunosuppression or as diagnostic tests in patients presenting with symptoms such as fever during neutropenia (FN). Out of 1,532 studies screened, 25 studies reported on GM (n=19), BG (n=3) and PCR (n=11). All fungal biomarkers demonstrated highly variable sensitivity, specificity and positive predictive values, and these were generally poor in both clinical settings. GM negative predictive values were high, ranging from 85-100% for screening and 70-100% in the diagnostic setting, but failure to identify non-Aspergillus molds limits its usefulness. Future work could focus on the usefulness of combinations of fungal biomarkers in pediatric cancer and HSCT.</p>
