The serum galactomannan index predicts mortality in hematopoietic stem cell transplant recipients with invasive aspergillosis.

We examined the relationship between serum and bronchoalveolar lavage (BAL) galactomannan index (GMI) values and mortality in allogeneic hematopoietic cell transplant recipients with invasive pulmonary aspergillosis. Using a clinical sign and symptom-initiated approach, we found that the serum but not the BAL GMI level correlated with 42- and 180-day patient mortality.
