Abstract

Objectives and aim: Invasive fungal pneumonia (IFP) has become increasingly common in patients that previously underwent
alloHSCT due to prolonged neutropenia, immunosuppressive therapies to prevent Graft-vs-host disease (GvHD) and widespread
use of broad-spectrum antibiotics. The aim of this study was to determine the role of hyperferritinemia in invasive fungal
pneumonia in patients that underwent alloHSCT.
Materials and Methods: Medical records of 73 patients with pneumonia that underwent alloHSCT were studied retrospectively,
whereby a pre-transplantation serum ferritin level measured up to 100 days prior to transplantation of patients with invasive
fungal pneumonia (IFP) and non-fungal pneumonia (non-IFP) was compared.
Results: Patient records revealed 35 and 38 cases of IFP and non-IFP respectively. All 35 patients diagnosed with IFP also
showed signs of probable pneumonia. Isolated causative microorganisms were Candida spp in five (14.2 %) of the patients and
Aspergillosis in three (8.6 %). In risk evaluation for IFP, age, gender, HLA status, conditioning regimen, CD34+ count, donor
gender, GVHD presence, smoking history, and underlying disease were not significantly different among groups (p > 0.05).
However, performance status (Karnofsky) was significantly lower in patients with IFP (p < 0.05), compared to the control group.
The median ferritin levels were 1705 ng/ml (41 − 7198) in the IFP group and 845 ng/ml (18 − 7099) in non-IFP group and the
difference was found statistically significant (p = 0.001).
Conclusion: Elevated pretransplant serum ferritin level is associated with IFP in patients that underwent alloHSCT, in particular
when values exceed 1550 ng/ml.
