Abstract

BACKGROUND:

Incidence, characteristics, and risk-factors for invasive aspergillosis (IA)-associated immune reconstitution syndrome (IRS) in lung transplant recipients are not known.

METHODS:

Patients comprised 68 lung transplant recipients with proven/probable IA followed for 12 months. IRS was defined based on previously proposed criteria.

RESULTS:

In all, 7.3% (5/68) of the patients developed IRS based on aforementioned criteria, a median of 56 days after initiation of antifungal therapy. This entity was associated with heart-lung transplantation (p=0.006), anti T-cell agent use (p=0.003), discontinuation of calcineurin inhibitor agent (p=0.002), and disseminated IA (p=0.069). In a risk assessment model, IRS developed in 0% (0/55) of the patients with none of the aforementioned factors, 28.6% (2/7) with one, 33.3% (1/3) with two, and in 1/1 patient with 3 factors (X(2) for trend p=0.0001). Three out of 5 patients with IRS died and 2 of 3 deaths in this group were due to chronic rejection.

CONCLUSIONS:

Overall 7% of the lung transplant recipients with IA appear to develop an IRS-like entity. Clinically assessable factors can identify patients at risk for post-transplant IA-associated IRS. Deaths due to chronic rejection were significantly higher in patients with IRS than those without IRS.
