Abstract:
OBJECTIVE:To analyze the relationship between miR451a and occult hepatitis B virus infection (OBI) in voluntary blood donors, and to provide ideas for the identification of OBI.
METHODS:A total of 125 003 blood samples were collected from voluntary blood donors in our center from January 2022 to June 2023, and OBI infection was detected by blood screening. At the same time, 40 HBsAg double reagent reactive samples (S/CO>3.0) were selected as the positive control group, and 40 healthy blood donors were selected as the negative control group (normal group). The plasma miR451a level was detected, and the serum indexes of total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST). The relationship between miR451a and OBI were analyzed.
RESULTS:54 out of 125 003 blood samples were diagnosed as OBI, and the OBI infection rate was 0.043% (54/125 003). Compared with the normal group, the relative expression of plasma miR451a in the OBI group and the positive control group was down-regulated (P < 0.05), but there was no significant difference in the relative expression of plasma miR451a between the OBI group and the positive control group (P >0.05). The HBV DNA load, TBil, ALT and AST levels in the positive control group were higher than those in the OBI group and the normal group (P < 0.05). There was no significant difference in plasma TBil, ALT and AST levels between OBI group and normal group (P >0.05). Logistic regression analysis and receiver operating curve (ROC) showed that plasma miR451a could distinguish OBI group from healthy group, and the area under the curve (AUC) was 0.904 (95%CI : 0.829-0.978). However, plasma miR451a was difficult to distinguish between OBI and HBsAg responders.
CONCLUSION:Plasma miR451a can be used as a potential biomarker for HBV infection, and can be used to identify OBI in HBsAg non-reactive blood donors.
