title: APRI and FIB-4 Scores Are Useful After Liver Transplantation Independently of Etiology.
abstract: Noninvasive liver fibrosis scores are evaluated in hepatitis C virus-infected patients but are less known in liver transplant recipients. Fibrosis is a frequent, multifactorial event in these patients. This preliminary retrospective study reviewed the diagnostic performance of 3 simple scores for liver fibrosis in transplant patients: namely, APRI (aspartate aminotransferase to platelet ratio index), FORNS (platelets, gamma-glutamyltransferase, patient age, and cholesterol), and FIB-4 (patient age, aspartate aminotransferase, alanine aminotransferase, and platelets). Ninety-four biopsies were collected from 50 liver transplant recipients at a mean period after orthotopic liver transplantation (OLT) of 30.7 months (range, 12-108 months). The indications for OLT were hepatitis C in 23% of cases, hepatitis B in 14%, alcoholic disease in 33%, cholestatic disease in 19%, and others in 11%. According to the Metavir classification, 72% of biopsies revealed no significant histological fibrosis (F0-1 = group 1) and 28% showed significant fibrosis (F2-4 = group 2). A correlation was observed between the histological stage of fibrosis and albumin, gamma-glutamyltransferase, aspartate aminotransferase, alanine aminotransferase, and hyaluronic acid levels. APRI and FIB-4 correlated significantly with the histological stage of fibrosis both globally and in the subgroup of nonhepatitis C liver recipients. When APRI and FIB-4 tests were applied to predict fibrosis (area under the receiver operating characteristic curve), the results were 0.87 and 0.78, respectively. Values were not significant with the FORNS test. In conclusion, APRI and FIB-4 enabled accurate prediction of significant fibrosis after OLT. In the nonhepatitis C subgroup, we found similar predictive performances. These simple scores may be applied in clinical practice in the context of follow-up after OLT independent of hepatitis C status.
