Abstract

AIM: The predictive value of circulating full-length cytokeratin 18 (M65) on prognosis of hepatitis B virus-related liver failure is still not well investigated. The aim of this study was to reveal the association between serum M65 levels and outcomes of hepatitis B virus-related acute-on-chronic liver failure, and to further clarify clinical significance of M65 in lamivudine treatment.

METHODS: Ninety-six patients with hepatitis B virus-related acute-on-chronic liver failure were recruited between January 2011 and December 2013, and 52 of them received lamivudine treatment. Blood were obtained from participants at admission, and M65 were determined by enzyme-linked immunosorbent assay. Other necessary data were collected from medical records.

RESULTS: The liver failure patients were divided into high and low level groups according to the serum M65 levels. After 24-week follow up, survival incidences were significantly higher in the low level group than that in the high level group (odds ratio [OR] = 0.3, 95% confidence interval = 0.1-0.7). In addition, the survival incidences and albumin levels improved in the patients with lamivudine treatment compared with the patients without lamivudine treatment in the low level group (OR = 5.4, 95% CI = 1.1-26.0 and OR = 4.2, 95% CI = 1.3-13.2). A similar improvement was not observed in the high level group.

CONCLUSION: The study suggested that the circulating M65 may serve as a relatively independent prognostic parameter for liver failure. If prospectively validated in further studies, M65 measurement may also be a useful method for optimizing antiviral therapy.
