Abstract
Invasive pulmonary aspergillosis (IPA) is an emerging disease associated with high mortality. The diagnosis is difficult, based on a combination of elements that are clinical, radiological and biological. For early detection of cases of IPA, during 25 months, we have systematically carried out on the LBA ( N = 355) of immunocompromised patients ( N = 313) a determination of Aspergillus galactomannan (GM) by ELISA (Platelia ® Aspergillus, BioRad). We observed 14 cases of probable API. The sensitivity of GM compared to direct examination (DE) and culture is, respectively, 64% versus 29% and 57%. The determination of GM is definitely more sensitive than the ED. Excellent specificity (98%) allows its implementation as a screening test in patients at risk.
