Abstract
The
management of hepatitis C virus (HCV) infection in patients with
decompensated cirrhosis has evolved dramatically over the past few years
mainly due to the availability of all-oral antiviral regimens. The
currently approved all-oral direct-acting antivirals (DAA) containing
sofosbuvir, ledipasvir, daclatasvir and ribavirin, in various
combinations, have shown to be safe and effective in patients with
decompensated cirrhosis with sustained virological response (SVR) rates
nearly comparable to those with well-compensated liver disease. Unique
issues yet remain such as the challenges with renal insufficiency,
tolerability of ribavirin and risk of further hepatic decompensation
with a protease inhibitor-based regimen. While most patients who achieve
SVR have demonstrated improvement in hepatic synthetic function over
the short course of follow, the long-term beneficial effects are
unknown. Further, the baseline predictors of improvement in hepatic
function have not been well delineated and thus have left us in a
quandary as to what we might expect with successful therapy and thus we
are at a loss to well educate our patients. The major concern, in
potential liver transplant candidates, is of unintended 'harm' by
achieving SVR but without improvement in hepatic function to an extent
where the patients might function well. As HCV therapies are as
effective in liver transplant recipients, there is a growing sentiment
in some of the transplant quarters that those with decompensated liver
disease and awaiting liver transplant be treated for HCV after liver
transplant. This strategy would thus eliminate any concern of leaving a
patient in 'no person's' land by treating HCV successfully pretransplant
but not to the point of functional normalcy, while also would maintain
the risk of HCC. Yet a contrarian view would be that not all patients
have access to liver transplantation (LT), cannot bear the cost, have
comorbidities or contraindications to LT. While the debate continues, it
is essential that we develop robust predictors of improvement in liver
function so that we can carefully select our patients for therapy in the
context of liver transplantation.
