Abstract

The diagnosis of invasive aspergillosis in neutropenic individuals is difficult and lengthy since non-invasive diagnostic tests lack sensitivity and specificity. The diagnosis of invasive aspergillosis in 154 prolonged neutropenic patients was prospectively bi-weekly validated by screening circulating galactomannan. The global sensitivity was 73% and specificity was 96%. The positive and negative predictive values were 73% and 98% respectively. False positive reactions occurred at a rate of 2%. Antigenemia was detected before clinical suspicion of invasive aspergillosis (median, 6 days before) in 30% of patients and anticipated the onset of radiologic signs 9 days in 60% of patients.

CONCLUSION:

the prospective screening of galactomannan is a sensitive and non-invasive tool for early diagnosis of invasive aspergillosis in high-risk adult hematology patients.
