ABSTRACT
Background. The Charlson Comorbidity Index for orthotopic liver transplantation
(CCI-OLT) is a modified clinical score recently proposed to be useful for the assessment
of long-term survival after OLT. It includes 9 associated conditions selected upon a
multivariate analysis of a large cohort of transplant recipients. Its role in predicting early
mortality after OLT has not yet been investigated. We sought to CCI-OLT as a potential
predictor of 1-month mortality after OLT.
Materials/Methods. One hundred ninety-seven OLT were performed in our center
between March 2002 and February 2009. After exclusion of patients who underwent
transplantation for fulminant hepatic failure or those who underwent regrafting, we
included a group of 169 patients. Viral (39%) and alcohol-induced (23%) cirrhosis were
the most common indications for OLT. The CCI-OLT index was assessed in all patients.
Results. In total, 146 (86%) subjects survived and 23 (14%) died within 1 month after
LT. Fifty-one (30%) patients suffered at least 1 comorbidity that was included in the
CCI-OLT. Direct comparison between survivor versus nonsurvivor groups showed no
significant difference in terms of the total frequency of comorbidities (30.1% vs 30.4%; P
.99) or the number or the type of comorbidity. The most commonly associated condition
in both groups was diabetes mellitus.
Conclusion. Unlike the case of long-term survival, CCI-OLT did not seem to predict
early (1-month) mortality after OLT.

REDICTION of posttransplantation survival among
orthotopic liver transplantation (OLT) patients is dif-
ficult. The MELD score has been initially introduced to
assess mortality among patients undergoing the TIPPS
(transjugular intrahepatic portosystemic shunt) procedure.
Since 2002 it has been used for donor liver allocation from
the transplant list in the United States and subsequently in
other countries.

Most recently, MELD has been observed
to be of excellent value to predict mortality among patients
with cirrhosis undergoing various surgical procedures.
However, as clearly demonstrated by Merion et al, MELD
(model for end-stage liver disease) is of no use to predict
the outcomes after transplantation.

Medical conditions,
such as diabetes mellitus (DM), coronary artery disease
(CAD), or chronic obstructive pulmonary disease (COPD),
may exert negative effects on survival after OLT. An index
called the Charlson Comorbidity Index (CCI), which has
been widely used the past, includes various associated
medical conditions.

It has been recently modified and
adopted in the liver transplantation setting, as the Charlson
Comorbidity Index—Orthotopic liver transplantation (CCI-
OLT). It has been shown to be helpful to predict long-term
mortality among patients undergoing OLT.

The aim of this study was to assess the predictive value of
CCI-OLT to assess early mortality after OLT.
