Role of continuous renal replacement therapy in management of the preliver transplant patient.

Purpose of review: Highlight the importance of acute kidney injury (AKI) among liver transplant candidates, its importance of survival and the vital role of continuous renal replacement therapy (CRRT) as a supportive therapy.

Recent findings: Kidney dysfunction is common in the preliver transplant patient. Early recognition, broad diagnostic work up, and therapeutic interventions are vital in minimizing morbidity and mortality in this critically ill group of patients. Liver dysfunction can impact kidney function in multiple ways, leading to worsening of clinical illness. High mortality and poor prognosis in those with AKI without CRRT and Liver Transplant are highlighted.

Summary: Etiology of AKI may not be as important as is the potential for liver transplant (LT) listing in offering CRRT. Non eligibility for a LT does not by default imply non eligibility for CRRT. Multidisciplinary approach should be adopted among those with a need for CRRT in the setting of end-stage liver disease. Goals of care conversations are key, in evaluating the role of CRRT in this group of individuals as they have a very high risk of mortality.
