Predictors of clinical trajectories of patients with acutely decompensated cirrhosis. An external validation of the PREDICT study

Abstract

AbstractBackground and AimsThe PREDICT study recently showed that acutely decompensated (AD) patients with cirrhosis can present three different clinical phenotypes in the 90 days after admission: (1) pre‐ACLF, developing acute‐on‐chronic liver failure (ACLF); (2) unstable decompensated cirrhosis (UDC), being re‐admitted for AD without ACLF and (3) stable decompensated cirrhosis (SDC), not presenting readmission or ACLF. This study aimed to externally validate the existence of these three distinct trajectories and to identify predictors for the occurrence of each trajectory.MethodsBaseline data, 3‐month ACLF and readmission incidence and 1‐year survival were analysed in a prospective cohort of patients admitted for AD. A multinomial multivariable model was used to evaluate the association between baseline features and clinical trajectories.ResultsOf the 311 patients enrolled, 55% met the criteria for SDC, 18% for UDC and 27% for pre‐ACLF, presenting a significantly different 1‐year mortality: pre‐ACLF 65%, UDC 46%, SDC 21% (p < .001). The presence of hepatic encephalopathy (HE) was associated with UDC (p = .043), while the absence of ascites to SDC (p = .017). Among laboratory parameters, an increase in MELD‐Na (p = .001) and C‐reactive protein (p = .009) and a decrease in haemoglobin (p = .004) and albumin (p = .008) levels were associated with pre‐ACLF.ConclusionThe present study confirms that AD patients have three different clinical trajectories with different mortality rates. Besides the severity of cirrhosis, the association with C‐reactive protein supports the predominant role of systemic inflammation in ACLF pathophysiology. Finally, HE is associated with the UDC phenotype highlighting the need for better management of this complication after discharge.
