Tacrolimus for the prevention and treatment of rejection of solid organ transplants.

Since its introduction to the antirejection armamentarium in 1994, tacrolimus has become the workhorse of transplant professionals for avoidance of solid organ transplant rejection. Not only does tacrolimus have potent immunosuppressive qualities that prevent rejection, but dosing is straight forward and it is generally well tolerated. However, in the long term, conditions such as calcineurin inhibitor nephrotoxicity can become a problem.

The benefit of sirolimus maintenance immunosuppression and rabbit antithymocyte globulin induction in liver transplant recipients that develop acute kidney injury in the early postoperative period.

Published data are limited describing renal outcomes in orthotopic liver transplant (OLT) recipients prescribed sirolimus (SRL) maintenance immunosuppression (MIS) and rabbit antithymocyte globulin (rATG) induction. We investigated whether SRL MIS and rATG induction facilitated recovery of acute kidney injury in the early postoperative period. This retrospective descriptive study screened 308 consecutive OLTs performed between 2006 and 2009.

Direct acting inhibitors of ammoniagenesis: a role in post-TIPS encephalopathy?

A limited number of medications are typically considered for the management of hepatic encephalopathy occurring as a complication of transjugular intrahepatic portosystemic shunt (TIPS) placement. Multiple alternative compounds aimed at disrupting ammoniagenesis are or will soon be available, though their use tends to be limited by a lack of large data sets and of clinical awareness. In this review, we provide a targeted overview of the mechanisms and availability of five anti-ammoniagenic compounds (sodium phenylbutyrate, glycerol phenylbutyrate, sodium benzoate, L-ornithine L-aspartate, and ornithine phenylacetate) identified as possibly useful alternative therapeutic agents for cirrhotic encephalopathy.
