The efficacy of these interventions, whether administered individually or in combination, is a prominent area of investigation in the management of liver failure among adult populations.

The patient cohort consisted of individuals admitted between January 1, 2021, and June 1, 2024, due to acute liver failure or acute-on-chronic liver failure. The analysis specifically included patients who underwent therapeutic plasma exchange (TPE) or those who received continuous renal replacement therapy in conjunction with TPE.
