CLIF-C AD Score Predicts Development of Acute Decompensations and Survival in Hospitalized Cirrhotic Patients

Patients with decompensated cirrhosis are at increased risk of mortality, even in absence of ACLF. The CLIF-C AD score (CLIF-C ADs) was proposed as a prognostic score but lacks sufficient validation. Our aim was to describe clinical characteristics and hospital evolution according to score groups and evaluate prognostic capability of CLIF-C ADs alone or in combination with other scores.

Two hundred and sixty-six patients (55 ± 14 years, ascites in 63%, MELD 14 ± 5) were included, and classified as high, intermediate and low CLIF-C ADs in 13, 60 and 27% of cases. Development of new complications of cirrhosis during hospitalization and survival at 3 months were evaluated.

Patients with high CLIF-C ADs had more severe systemic inflammation parameters and higher frequency of organ dysfunction. CLIF-C ADs ≥ 60, when compared to intermediate and low groups, was associated with higher incidence of complications of cirrhosis (90% vs 70% and 49%, p < 0.001) and lower survival (93%, 80% and 50%, p < 0.0001). In multivariate analysis, CLIF-C ADs, ascites and MELD were predictors of survival [(AUROC 0.76 (95% CI 0.69-0.83)]. Absence of ascites or MELD < 14 identified patients with intermediate CLIF-C ADs and good survival (89 and 84%, respectively).

CLIF-C ADs predicts survival in cirrhotic patients with AD. High CLIF-C ADs is associated with higher frequency of organ dysfunction, increased risk of new complications of cirrhosis and high short-term mortality. On the contrary, individuals with low CLIF-C ADs, as well as those with intermediate score without ascites or with low MELD have excellent prognoses.
