Methods: A prospective multicenter analysis of the Fungitell assay was performed on BAL and serum samples obtained from nonselected solid-organ transplantation patients suffering from probable, proven or no IFI according to the revised criteria of the European Organisation for Research and Treatment of Cancer / Mycosis Study Group. The performance characteristics of the Fungitell assay in BAL have been determined by Viracor-Eurofins; there are no established criteria for the interpretation of Fungitell results from BAL fluid. Of these 41 patients, 37 demonstrated serum (13)--D-glucan concentrations above the determined cut-off value. Obayashi T, Sugimoto A, Takigawa C, Sekiya N, Nagasawa J, Ozaki Y. Med Mycol J. Studies have shown that glucan levels become elevated in fungal infection in advance of conventional clinical signs and symptoms. Mattiuzzi European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group, Oxford University Press is a department of the University of Oxford. The diagnoses of invasive fungal infections have historically been made difficult by the need for invasive methods. 1. . MeSH The general outline for the assay procedure is summarized in Figure 3. The chromogen, p-nitroanilide, is colorless when attached to a peptide but changes to a yellow color when cleaved from the synthetic peptide.14 While the original LAL was based on observing the end-point of the gel clot formation, the beta-glucan LAL is a colorimetric assay and the end-point is based on determining the absorbance at 450 nm.11,14 Finally, it has been observed that serum samples have an inherent yellow color that may alter the end-point absorbance (overestimate); therefore, 1 variation of the beta-glucan LAL determines the absorbance of the diazo derivative of p-nitroanilide, which is purple.11. 2021 Aug 26;16(8):e0255172. They established the 6079 pg/mL as the indeterminate range for result reporting, with the negative range for the assay being below 60 pg/mL. . The glucan component is predominantly composed of glucose polymers linked in a linear arrangement by carbons 1 and 3 through a glycosidic bond with a beta configuration (Figure 1) to form the (13)--D-glucan backbone.7 The biosynthesis of this polysaccharide backbone involves the transportation of glucose subunits to the plasma membrane, where they are then transported across the plasma membrane and arranged by a linear (13) glycosidic bond.5 The enzyme responsible for the formation of this polysaccharide backbone is (13)--D-glucan synthase.47 The polysaccharide backbone is typically 1500 glucose subunits in length, but within each chain branching occurs with either a (14) or (16) glycosidic bond.7 The branching assignments are highly variable and specific to the fungal species. Units. Finally, beta-glucan testing might be useful in the diagnosis of other invasive fungal infections (eg, histoplasmosis) with the exception of Mucor, Rhizopus, Blastomyces dermatitidis, and Cryptococcus species, but again, more trials are needed to confirm assay performance and to determine the role of this assay detecting infections with these pathogens.8,9,1517,20,24. In 1968, a carboxy-methylated beta-glucan that was being evaluated as an anti-tumor agent was observed to induce clotting with the LAL despite the absence of demonstratable bacterial contamination.12 A second serine protease zymogen, Factor G, was subsequently determined to be the factor responsible for initiating the LAL clotting cascade by this beta-glucan determinant.12,13 The assays developed specifically to measure fungal beta-glucan typically use serum and rely on the activation of the LAL clotting cascade as the biological principle of detection.4,13 The beta-glucan LAL pathway is summarized in Figure 2. S However, these techniques commonly require invasive sample collection methods (eg, biopsy, bronchoalveolar lavage), which may be contraindicated in certain patients. S et al.
