infections after liver transplantation: outcomes and risk factors
revisited in the MELD era.
Abstract: Antifungal prophylaxis is recommended in high-risk patients,
but risk criteria remain unclear and the predictive value of Model of End-
Stage Liver Disease (MELD) score is unknown. In a retrospective, single-
center analysis of 667 liver transplants, potential risk factors for fungal
infection were assessed, including MELD score. Antifungal prophylaxis
was administered in 198 patients (29.4%). During follow-up (mean
43.6 29.6 months), 263 patients (39.4%) developed 1 episode of
fungal infection, and 187 (28.0%) patients developed a probable or
proven invasive fungal infection requiring systemic antifungal treatment.
Patients receiving antifungal prophylaxis had a lower incidence of fungal
infection (29.8% vs. 43.5% without prophylaxis, p < 0.001) and invasive
fungal infection (17.7% vs. 32.4%, p < 0.001). One-yr patient survival
was 91%, 85% and 69%, respectively, in patients with no fungal
infection, fungal colonization and treated invasive fungal infection
(p < 0.001); graft survival was 88%, 85% and 66% (p < 0.001).
Multivariate analysis indicated that MELD score of 20–30 or 30 was
associated with a 2.0-fold or 4.3-fold increase in relative risk of fungal
infection, respectively, and a 2.1-fold or 3.1-fold increase in relative risk
of invasive fungal infection. In conclusion, liver transplant patients with
a MELD score 20, and particularly patients with a score 30, are
candidates for antifungal prophylaxis.

Although the incidence of invasive fungal infection
following liver transplantation has declined since
the mid-1990s (1–3), such infections still develop in
approximately 5–20% of patients (4) and represent
a significant burden in terms of mortality and mor-
bidity (5). Candida and Aspergillus infections
account for 70–90% of invasive fungal infections
in solid organ transplant recipients (4, 6), with liver
transplant patients showing a particularly high sus-
ceptibility to Candida species (7, 8). Candidiasis
and aspergillosis typically occur early post-trans-
plant (4, 8), the time at which the intensity of
immunosuppressive regimens is highest and the
immune status of the recipient is weakened by
illness, the surgical procedure and the hospital
microbiological environment. Despite the absence
of a real consensus, short-term antifungal prophy-
laxis is currently recommended after liver trans-
plantation in patients considered to be at high risk
for fungal infection (9, 10).
The criteria for identifying high-risk recipients,
however, remain unclear. In the mid-1990s, a series
of analyses identified a range of possible risk fac-
tors for invasive infections, including pre-trans-
plant or early post-transplant colonization (2, 11,
12), poor pre-transplant renal function (2, 11), a
complex transplant procedure as indicated by high
use of blood products, choledochojejunostomy
anastomosis or long surgical time (1, 2, 11, 12),
and a difficult post-operative course with extended
stay in the intensive care unit (ICU) or bacterial
infection (1, 12). One of these studies (11) and a
