INTRODUCTION: The aim of this study was to evaluate the correlation of High-mobility group box 1 (HMGB1) expression in the serum with chronic hepatitis B (CHB) related liver fibrosis, severe hepatitis B and acute-on-chronic liver failure (ACLF).
EVIDENCE ACQUISITION: We made a literature search in PubMed, Embase, Web of Science, Medline, Google Scholar, China National Knowledge Infrastructure, WanFang with no language restriction. Pooled data were analyzed and mean difference with corresponding 95% confidence intervals were calculated.
EVIDENCE SYNTHESIS: A total of 16 relevant studies were identified. HMGB1 serum levels were higher in severe hepatitis B or ACLF patients than those in CHB patients. Pooled mean differences of HMGB1 in severe hepatitis B and ACLF patients compared with CHB patients were 4.32 (95% CI: 0.34-8.29, Z=2.13, I2=59%, P=0.03) and 15.96 (95% CI: -0.37-32.28, Z=1.92, P=0.06). Four studies showed there was a different HMGB1 expression in mild, moderate and severe CHB patients (P values were <0.05, <0.05, <0.05 and <0.01, respectively). Pooled mean difference of HMGB1 in low liver fibrosis patients compared with high liver fibrosis was -125.38 (95% CI: -539.44-288.68, Z=0.59, I2=98%, P=0.55).
CONCLUSIONS: The results suggested that HMGB1 levels in the serum were statistically higher in severe hepatitis B and ACLF patients. Therefore, HMGB1 may be a useful therapeutic target for severe hepatitis B and ACLF diagnosis.
