As conventional microbiological documentation of invasive aspergillosis (IA) is difficult to obtain, serum fungal biomarkers are important adjunctive diagnostic tools. Positivity rates and the kinetic profiles of galactomannan (GM), 1,3-β-D-glucan (BDG) and Aspergillus DNA (PCR) were studied in high-risk patients with hematologic malignancies. GM, BDG and PCR data from serial serum specimens (n = 240) from 93 adult hematology patients with probable (n = 8), possible (n = 25) and no (n = 60) IA were retrospectively analyzed. Positivity rates and sensitivity/specificity/positive/negative predictive values (NPV) of each fungal biomarker alone and in combination were estimated. The three markers were compared head-to-head and correlated with various biochemical, demographic and patient characteristics. The positivity rates for patients with probable/possible/no IA were 88%/8%/0 % for GM (X2 = 55, p < 0.001), 62%/46%/35% for BDG (X2 = 2.5, p = 0.29), 62%/33%/27% for PCR (X2 = 3.9, p = 0.15), 50%/4%/0% for GM + BDG and GM + PCR (X2 = 31, p < 0.001), 50%/8%/22% for BDG + PCR (X2 = 6.5, p = 0.038) and 38%/4%/0% for GM + BDG + PCR (X2 = 21, p < 0.001). Higher agreement (76%) and negative correlation (rs = -0.47, p = 0.0017) was found between GM index and PCR Ct values. The sensitivity and NPV was 45-55% and 90-92% when biomarkers assessed alone and increased to 75-90% and 93-97%, respectively when combined. Weak significant correlations were found between GM, PCR and BDG results with renal/liver function markers (r = 0.11–0.57) with most GM+ and PCR+ samples found in the first and second week of clinical assessment, respectively and BDG later on. Different positivity rates, time profiles and performances were found for the three biomarkers advocating the combination of GM with PCR for the early diagnosis of IA, whereas the high NPV of combined biomarkerscould help excluding IA.

Introduction. During the past decades a dramatic increase in the incidence of invasive fungal diseases, especially invasive aspergillosis has been observed. Undiagnosed and diagnosed late invasive aspergillosis is followed by lethality of up to 90%. Detection of early laboratory biomarkers (galactomannan and anti-Aspergillus antibodies) contributes to early diagnosis and is used for screening, as well as for monitoring therapy of aspergillosis. Objective. The aim was to evaluate usefulness of ?non-culture? methods (galactomannan and anti-Aspergillus antibodies IgA, IgM and IgG) for early diagnosis of aspergillosis in high-risk patients. Methods. Prospective two-year study involved 262 high-risk patients for aspergillosis. In pulmonology and haematology patients (adults and children) blood samples were tested on galactomannan and anti-Aspergillus antibodies. Results. Early laboratory biomarkers were statistically significantly higher in pulmonology patients (p=0.00033). However, in haematological patients galactomannan was a more frequently positive finding, while in pulmonology patients it was the finding of anti-Aspergillus antibodies. It is interesting that, despite the possible immunosuppression, in about 1/3 of haematological patients anti-Aspergillus antibodies were confirmed. Conclusion. Early diagnosis and treatment of aspergillosis represent both clinical and laboratory problem. Nowadays, the application of new ?non-culture? methods is of particular importance for the outcome of aspergillosis. Clinical features, laboratory findings of biomarkers and their correct interpretation significantly increase the possibility of timely implementation of appropriate therapy. In this regard, the new organization of reference laboratory for medical mycology has significantly improved the outcome of aspergillosis in high-risk patients in our country. However, further investigations, implementation of European standards and introduction of new diagnostic methods are necessary in this field.
