Abstract

Invasive aspergillosis is an opportunistic infection that is mainly caused by Aspergillus fumigatus, which is known to produce several secondary metabolites, including gliotoxin, the most abundant metabolite produced during hyphal growth. The diagnosis of invasive aspergillosis is often made late in the infection because of the lack of reliable and feasible diagnostic techniques; therefore, early detection is critical to begin treatment and avoid more serious complications. The present work reports the development and validation of an HPLC-MS/MS method for the detection of gliotoxin in the serum of patients with suspected aspergillosis. Chromatographic separation was achieved using an XBridge C18 column (150x2.1 mm id; 5 mm particle size) maintained at 25°C with the corresponding guard column (XBridge C18, 10x2.1 mm id, 5 mm particle size). The mobile phase was composed of a gradient of water and acetonitrile/water (95:5 v/v), both containing 1 mM ammonium formate with a flow rate of 0.45 mL min -1 . Data from the validation studies demonstrate that this new method is highly sensitive, selective, linear, precise, accurate and free from matrix interference. The developed method was successfully applied to samples from patients suspected of having aspergillosis. Therefore, the developed method has considerable potential as a diagnostic technique for aspergillosis. © 2014 Cerqueira et al.
