Diagnostic Potential of microRNA-122 for Stage Classification in Patients with HBV-Related Cirrhosis
Objective:
Previous studies have suggested that microRNA-122 has a relatively high diagnostic value for chronic viral hepatitis detection. In this study, we evaluated the diagnostic value of serum microRNA-122 in different stages of HBV-related cirrhosis，and serum microRNA-122 may serve as a potential biomarker for staging HBV related cirrhosis patients..
Methods:
A total of 80 patients with HBV-related cirrhosis were included. Patients were characterized according to Child-Pugh score, laboratory parameters, and complications, and divided into compensated cirrhosis group and decompensated cirrhosis group. Wherein, the compensatory group for liver cirrhosis includes 21 patients, the compensatory group has 59 patients. Blood was collected from all patients, and RT-qPCR analyzed the expression levels of microRNA-122.
Results:
Serum microRNA-122 was decreased, while Child-Pugh score, Meld score, Prothrombin time, total bilirubin, and Direct bilirubin were higher in a decompensated group compared to the compensated group (all P < .05). For further stage classification, the mean serum microRNA-122 level was higher in stage 1 (11.3±5.1, compensated cirrhosis) compared to stage 2~5 (8.5±4.2, 4.9±1.0, 4.7±1.6, 3.5±1.1, decompensated cirrhosis, all P < .05). The expression of serum microRNA-122 independent of Child-Pugh score and complications, including ascites, varices, HCC (P > .05).However it was affected by Meld score and Prothrombin time (P < .05). Moreover, ROC analysis indicated microRNA-122 could differentiate compensated HBV-related cirrhosis (0.97 of AUC, P < .01). Furthermore, it could differentiate patients in stage 1 (compensated cirrhosis without esophageal varices) from HBV-related cirrhosis (0.91 of AUC, P < .01), with a sensitivity of 77.8% and satisfactory specificity of 88.7%. The significance of the relationship between the decrease in serum microRNA-122 levels and the stage of liver cirrhosis will be beneficial.
Conclusion:
Our results strongly support the diagnostic value of serum microRNA-122 as a potential biomarker of stage classification in patients with HBV-related cirrhosis, which could facilitate risk stratification and careful management. Provide new biomarkers for the diagnosis of patients with hepatitis B cirrhosis.
