摘   要:

Invasive pulmonary aspergillosis (IPA) is a life-threatening complication in patients receiving chemotherapy or undergoing allogeneic haematopoietic stem cell transplantation for acute leukemia. The existing tools to diagnose IPA lack specificity or sensitivity, or both; the search for improved diagnostic tools for IPA has focused on novel serologic and molecular methods. Aspergillus Galactomannan enzyme-linked immunosorbent assay (GM) analyses showed sensitivity rates in serum samples ranging in a wide span; testing GM in bronchoalveolar lavage (BAL) originated from the primary site of the infection seems to be more sensitive in patients with IPA. Other novel diagnostic markers to detect fungal DNA directly in clinical samples, rapidly, early, sensitively and specifically, are provided by polymerase chain reaction (PCR) based assays; higher sensitivity and specificity rates have been observed for BAL samples in IPA, even under antifungal treatment. The clinical place value of a diagnostic approach combining PCR and GM in BAL is unclear.
