Quantifying the impact of a novel virus on the economic value of pathogen reduction technology for platelets.

Background: Pathogen reduction technology (PRT) is an intervention designed to proactively reduce the amount of known and unknown pathogens in donated blood. As current screening for known pathogens is highly effective, some previous evaluations have found that the value of PRT largely hinges on a previously unknown pathogen, most likely a novel virus, emerging and entering the blood supply. In such situations, the risk of emergence can and should be modeled and presented transparently in the cost-effectiveness results for deliberation by decision-makers.

The evolution of the liver transplant candidate.

The first successful human liver transplant (LT) was done over 60 years ago; since the early pioneering days, this procedure has become a routine treatment with excellent outcomes for the great majority of recipients. Over the last six decades, indications have evolved. Use of LT for hepatic malignancy is becoming less common as factors that define a successful outcome are being increasingly defined, and alternative therapeutic options become available.

Primary biliary cholangitis drug evaluation and regulatory approval: Where do we go from here?

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease. The management landscape was transformed 20 years ago with the advent of ursodeoxycholic acid. Up to 40% of patients do not, however, respond adequately to ursodeoxycholic acid and therefore still remain at risk of disease progression to cirrhosis.
