Potential of Apolipoprotein A1 (ApoA1) for Detecting Liver Cirrhosis and Hepatocellular Carcinoma.

objectiveLiver cirrhosis and hepatocellular carcinoma (HCC) are chronic liver diseases that can cause serious health problems. Meanwhile, the methods used to detect liver cirrhosis and HCC are limited. Apolipoprotein A1 (ApoA1) is a protein that makes up high-density lipoprotein (HDL), which plays a role in liver cirrhosis and HCC, and can be used as a biomarker. This study aims to determine the ability of ApoA1 to detect and differentiate liver cirrhosis and hepatocellular carcinoma.

methodsThis cross-sectional study was conducted on 47 patients with liver cirrhosis and HCC at Margono Soekarjo Regional General Hospital, Purwokerto, Indonesia. This study also involved 33 healthy participants from blood donors at the Blood Transfusion Unit, Indonesian Red Cross, Banyumas. Serum ApoA1 levels were analyzed by ELISA method. Receiver Operating Characteristics (ROC) were used to evaluate the diagnostic power of ApoA1 and differentiate between cirrhotic, HCC, and healthy patients. Multivariate binary logistic regression test to determine the most influential variables on the incidence of cirrhosis, HCC, and health.

resultsApoA1 was able to differentiate cirrhosis from HCC, cirrhosis from healthy and HCC from healthy, with sensitivity 56.7%, 86.7%, 70.6%, specificity 70.6%, 93.9%, 84.9%, respectively, and AUC 68.5%, 92.6%, 75.0%. AFP (p = 0.002, OR 1.004) and bilirubin (p = 0.021, OR 1.259) were variables that contributed to cirrhosis - HCC. Age (p = 0.011, OR 0.766) and AST (p = 0.003, OR 0.834) are variables that play a role in health - cirrhosis. ALT (p = 0.024, OR 0.965) and PT (p = 0.004, OR 0.253) are variables that play a role in healthy - HCC.

conclusionApoA1 was best for detecting healthy from cirrhosis, followed by healthy from HCC and cirrhosis from HCC. ApoA1 is not the primary variable determining the incidence of cirrhosis - HCC, healthy - HCC, and healthy - HCC.
