Response to LIVint-15-00100

Although AST-to-platelet ratio index (APRI) and FIB-4 have been compared with liver biopsy in patients with hepatitis C virus (HCV), hepatitis B virus (HBV), HIV/HCV co-infection, and HIV/HBV co-infection, Johannessen and Lemoine stress that they have not been validated in HIV mono-infected populations in SSA. However, this is unlikely to occur because liver biopsy does not play a role in HIV management and the procedure carries its own risks for complication. Clinicians using APRI and FIB-4 in this setting should be aware of this limitation and should interpret test results in the context of each patient's clinical scenario.
